10 1342705 It appears that immune responses that preferentially involve T helper 1 cells (secretors of interleukin-2-and interferon-gamma) tend to be protective, whereas T helper 2 cells (secretors of IL-4, IL-5, IL-6, and IL-10), a population that antagonizes T helper cells, mediate disease susceptibility and are involved in immunopathological reactions.
11 1342705 Administration of IL-2 and IFN-gamma has beneficial effects in many infections mediated by viruses, bacteria, and protozoa.
12 1356911 Various membrane proteins of Francisella tularensis induce interferon-gamma production in both CD4+ and CD8+ T cells of primed humans.

14 1356911 CD4+ T cells, but not CD8+ T cells, proliferated and produced IFN-gamma.
15 1356911 However, when CD8+ T cells were isolated from bulk cultures of lymphocytes, which had been stimulated with antigen for 3 days, they responded to an extent similar to that of CD4+ T cells.
16 1356911 Purified CD8+ T cells also responded when they were supplemented with interleukin-2 (IL-2).
17 1356911 There was a direct quantitative correlation between the proliferative response of CD4+ and CD8+ T cells and their production of IFN-gamma.
18 1356911 IL-2 was produced in the cultures, the amounts being higher in the cultures of CD4+ than in those of CD8+ cells.
19 1356911 When proliferating, these clones did invariably produce IL-2 and IFN-gamma but no IL-4.
20 1356911 In conclusion, both CD4+ and CD8+ T cells of tularaemia-vaccinated individuals respond with proliferation to various protein antigens of F. tularensis, and the proliferative response is strictly associated with IFN-gamma production.
21 1356911 The CD8+ T-cell response seems to depend on cytokines supplied by proliferating CD4+ T cells.
22 1356933 A single injection of monoclonal antibody to gamma interferon administered in conjunction with a live Candida albicans yeast cell vaccine resulted in the detection of nonprotective Th2 rather than protective Th1 responses and altered the early expression of interleukin 4 and gamma interferon mRNA in CD4+ cells.

51 1670604 When stimulated with crude tachyzoite Ag in vitro, CD4+ cells from vaccinated mice produced high levels of TH1 cytokines (IL-2 and IFN-gamma) but not TH2 cytokines (IL-4 and IL-5).
52 1670604 CD8+ cells, in contrast, produced less IFN-gamma and no detectable IL-2.
53 1670604 Nevertheless, they could be induced to synthesize IFN-gamma when exposed in culture to exogenous IL-2.
54 1670604 These results suggest that although IFN-gamma and IL-2-producing CD4+ lymphocytes are induced by vaccination, IFN-gamma-producing CD8+ T cells are the major effectors of immunity in vivo.
55 1670604 Nevertheless, CD4+ lymphocytes appear to play a synergistic role in vaccine-induced immunity, probably through the augmentation of IFN-gamma synthesis by the CD8+ effector cells.
56 1690777 All but one of the clones were CD4+, CD5+, Th cells.
57 1690777 One clone, 35, produced Il-2 and IFN-gamma and was designated a TH1 clone.
58 1690777 IFN-gamma and TNF-alpha were essential to the killing mechanism whereas Il-1, Il-2, and Il-4 were not required.
59 1704342 For this purpose short synthetic peptides corresponding to these epitopes were used to study the induction of in vitro expression of IL-4 mRNA, IFN-gamma secretion, proliferation and B cell help for antibody production.
60 1729188 These T cells produced interleukin 2 and gamma interferon but no detectable interleukin 4 and interleukin 5.
61 1827920 We have established a large panel of T-cell clones (TCCs) specific for Dermatophagoides pteronyssinus and Lolium perenne group I grass pollen allergens (total, 61) and for tetanus toxoid and protein purified derivative bacterial antigens (total, 38) from the peripheral blood of two atopic individuals and then analyzed their ability to produce interleukin 4 (IL-4), IL-5, and interferon gamma (IFN-gamma).
62 1827920 Upon stimulation with phorbol 12-myristate 13-acetate plus anti-CD3 antibody, the great majority of TCCs specific for bacterial components was able to produce both IL-4 and IFN-gamma, whereas most D. pteronyssinus- and L. perenne group I-specific TCCs produced IL-4, but no, or limited, IFN-gamma.
63 1827920 Moreover, the mean amounts of IL-4 and IFN-gamma released by allergen-specific TCCs were significantly higher and lower, respectively, than the mean amounts produced by TCCs specific for bacterial components.
64 1827920 Under these experimental conditions, all allergen-specific TCCs, but only one-third of TCCs specific for bacterial components that produced IL-4 but no, or little, IFN-gamma induced the synthesis of detectable amounts of IgE.
65 1827920 The demonstration that most allergen-specific helper T cells in atopic individuals are able to produce high amounts of IL-4 (and IL-5), but no IFN-gamma, may explain why allergens induce production of IgE antibodies and increase eosinophils.

73 1827920 Moreover, the mean amounts of IL-4 and IFN-gamma released by allergen-specific TCCs were significantly higher and lower, respectively, than the mean amounts produced by TCCs specific for bacterial components.
74 1827920 Under these experimental conditions, all allergen-specific TCCs, but only one-third of TCCs specific for bacterial components that produced IL-4 but no, or little, IFN-gamma induced the synthesis of detectable amounts of IgE.
75 1827920 The demonstration that most allergen-specific helper T cells in atopic individuals are able to produce high amounts of IL-4 (and IL-5), but no IFN-gamma, may explain why allergens induce production of IgE antibodies and increase eosinophils.

87 1833466 Resistance to Leishmania major in mice is associated with the generation of distinct CD4+ Th subsets, termed TH1 and TH2.
88 1833466 Lymph node (LN) cells collected 3 days after infection of BALB/c mice secreted IL-4 and IL-5 in vitro, but little IFN-gamma, whereas LN cells from a resistant strain, C3H/HeN, secreted IFN-gamma and no IL-4 or IL-5.
89 1833466 Cytokine production was eliminated in both cases by in vivo or in vitro depletion of CD4+ cells, but not after depletion of CD8+ cells.
90 1833466 We next investigated whether IFN-gamma was important in the differentiation of Th1 and Th2 cells.
91 1833466 We confirmed this observation and found that the abrogation of resistance was associated with enhanced production of IL-4 and IL-5, and decreased production of IFN-gamma by cells taken from these mice.
92 1833466 Conversely, LN cells from BALB/c mice inoculated with parasites plus IFN-gamma produced significantly higher levels of IFN-gamma, and decreased levels of IL-4 and IL-5, than mice infected with parasites alone.
93 1833466 We found that s.c. immunization with soluble leishmanial Ag, the bacterial adjuvant, Corynebacterium parvum and IFN-gamma could protect mice against L. major infection, and that this protection was associated with induction of Th1 responses.
94 1833466 From these data we conclude that levels of IFN-gamma at the time of infection or immunization dramatically alters the type of response elicited: high levels of IFN-gamma favor Th1 type responses, whereas low levels promote a Th2 response.

120 1901883 In the non-curing B10.D2/n strain, late phase of infection was associated with the decreased ability to produce cytokines in response to Ag and not with the production of IL-4 or IL-5 in response to Ag or mitogen.
121 1901883 Together, these data suggest that over-expansion of Th2-type cells and production of their specific cytokines (IL-4 and IL-5) is not a contributing factor to the variable long term course of L. donovani infection in these strains of mice.

131 1909711 Positive in vitro T-cell responses in the form of lymphocyte proliferation and lymphokine interleukin 2 (IL-2) and gamma interferon (IFN-gamma) secretion are found in memory immunity.
132 1909711 Positive reactions, i.e., responses exceeding those on day 0, were reached on day 10 with regard to the whole blood culture DNA synthesis response and IL-2 and IFN-gamma secretion and on day 14 with regard to the mononuclear cell DNA synthesis response and tumor necrosis factor alpha (TNF-alpha) secretion.
133 1909711 If it is shown later that specific T cells produce it, the TNF-alpha response and the negative IL-4 finding may speak for the importance of the Th1-like pattern in immunity to F. tularensis.

136 1967279 In the present study, we investigated the lymphokine production patterns in a series of CD4+ and CD8+ host-reactive T cell clones isolated from PBL of a SCID patient, who was immunologically reconstituted by two allogeneic fetal liver and thymus transplantations 13 years ago.
137 1967279 In contrast, CD4+ tetanus toxin-specific T cell clones isolated from the same patient and having the same HLA phenotype produced normal amounts of IL-4 upon activation.
138 1967279 Furthermore, different modes of activation resulted in simultaneous production of IL-5, IL-2, IFN-gamma, granulocyte/macrophage-CSF, and transcription of the TNF-beta gene by the host-reactive clones, indicating that the lack of IL-4 production is not related to the mode of activation.

208 2115172 Production by activated human T cells of interleukin 4 but not interferon-gamma is associated with elevated levels of serum antibodies to activating malaria antigens.
209 2115172 Activation was measured as induction of interferon-gamma secretion, T-cell proliferation (DNA synthesis), or transcription and translation of interleukin 4 (IL-4) mRNA.

221 2123823 Mycobacterium-specific T cells from both BALB/c and B10.D2 mice produced interleukin-2 and no interleukin-4.
222 2123823 This suggests that tumor necrosis factor, in addition to gamma interferon, may be involved in resistance to L. major and that interleukin-4 may inhibit the leishmanicidal activity of tumor necrosis factor and/or gamma interferon.

225 2144549 The activated T cells are mainly CD4+ and secrete IL-2 and IFN-gamma but no IL-4.
226 2526739 Levels of cytokine mRNA coding for granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon-gamma (IFN-gamma), interleukin (IL) 2, IL 1 beta, IL 4 or IL 6 have been measured by Northern blot analysis after antigen stimulation.
227 2526739 With some variations among donors, antigens clearly induced measurable levels of IFN-gamma, GM-CSF and IL 2 mRNA.
228 2971718 The IL-4-mediated IgG and IgM production was neither suppressed by IFN-gamma nor by anti-CD23 mAb 25, whereas these agents have been shown earlier to inhibit IgE production of enriched B cells cultured in the presence of IL-4.
229 7483764 In cultures of RS virus primed LNC challenged with whole virus there was a switch of cytokine production from 70% IL-2 at day 3 to 80% IL-4 by 6 days of culture.
230 7483764 These data suggest that after 6 days of challenge with viral antigen, the RS virus-primed LNC response consists of T helper cells which are predominantly of the Th2 subset, secreting IL-4, whilst F protein-primed LNC secrete large quantities of IL-2 and can therefore be classified as predominantly of the Th1 subset.

233 7489749 We, therefore, generated DC from peripheral blood of normal donors in the presence of granulocyte/macrophage colony-stimulating factor and interleukin-4.
234 7489749 Flow cytometric analysis of the cells during a 2-week culture revealed a loss of CD14 and CD34 expression, a concomittent increase of CD1a, CD11a,b and c, CD44, CD45, CD54, HLA-class I and II, and intermediate levels of CD26, CD80 and CD86.
235 7492350 A similar effect by exogenous IL-2, or the same concentration of IL-4, was observed in 8/11 (P = 0.02) and 5/6 respectively DH, and 3/4 normal gut T cell lines.
236 7493774 Tuberculin-induced expression of IFN-gamma, IL2, IL4, IL10 and TNF-alpha mRNA occurred in the skin biopsies of all of the lesioned, M. bovis inoculated animals except for an absence of tuberculin-induced TNF-alpha mRNA expression in two animals.
237 7493774 By 28 weeks after vaccination, the three BCG-vaccinated, sham-inoculated cattle displayed minimal skin swelling response to tuberculin, but tuberculin-induced expression of IFN-gamma, IL2, IL4, IL10 and TNF-alpha mRNA was observed in skin biopsies of all of these animals.

240 7513306 Likewise, cells from recovered animals released gamma interferon and either interleukin 2 (IL-2) or IL-4 into culture media in response to both of the above-mentioned antigens, whereas cells from control animals did not.
241 7513919 Lymph node cells from immunised mice produced IL-2 and IL-4 when specifically recalled in vitro, indicating stimulation of both Th1 and Th2 helper cell compartments.
242 7525715 Relative efficacy of IL-2, IL-4, and granulocyte-macrophage colony-stimulating factor.
243 7525715 Here, we demonstrate that fusion proteins with IL-2 or IL-4 can also be highly immunogenic.

251 7525727 A similar, although less dramatic, increase in two other macrophage-activating cytokines, TNF-alpha and IL-2, also was observed.
252 7525727 In contrast, although the Th2 cytokines IL-4, IL-5, IL-10, and IL-13 were elevated in challenged vaccinated animals, only IL-10 and IL-13 showed increases that were significant with respect to the mRNA levels observed in challenged controls.
253 7525727 Neutralization of IFN-gamma reduced immunity in vaccinated animals and resulted in decreased IFN-gamma, IL-2, IL-10, TNF-alpha, and IL-12 p40 but markedly increased IL-4, IL-5, and IL-13 mRNA expression and serum IgE levels.
254 7525727 Furthermore, the observation that the down-regulatory cytokines IL-4, IL-10, and IL-13 are induced together with IFN-gamma may provide an explanation for the failure of this vaccine to provide complete protection.
255 7525727 A similar, although less dramatic, increase in two other macrophage-activating cytokines, TNF-alpha and IL-2, also was observed.

263 7538449 These T cell lines proliferated and produced interleukin-2 (IL-2) and/or IL-4, but only in the presence of the relevant BRM and BALB/c spleen cells as the antigen and antigen-presenting cells respectively.
264 7544248 We report here that by conjugating to ISCAR a 19mer peptide containing linear B epitopes, a T helper (Th) epitope, and a H-2b-restricted T cytotoxic (CTL) epitope of E7 protein of human papillomavirus type 16 (HPV16), and immunizing C57B1/6 (H-2b) mice, we elicited (i) specific IgG2a and IgG1 antibodies; (ii) IL-2 and IL-4 production by specifically recalled lymph node cells in vitro; (iii) cytotoxic T lymphocytes which specifically killed both E7 peptide-pulsed, and whole E7 gene-transfected tumour target cells; and (iv) in vivo protection against an E7 gene-transfected tumour cell inoculum.
265 7553683 We tested biopsy specimens of eight subcutaneous metastases that had developed inflammation following vaccine treatment for expression of mRNA for interferon gamma (IFN gamma), interleukin-4 (IL-4), tumor necrosis factor alpha (TNF alpha), and IL-10.
266 7553683 Post-vaccine, inflamed biopsies contained mRNA for IFN gamma (5/8), IL-4 (4/8) or both (3/8), and for TNF alpha (4/7).
267 7553683 In contrast, IFN gamma mRNA was detected in only 1/17 and TNF alpha mRNA in 2/16 control specimens (pre-treatment lymph node metastases or non-inflamed subcutaneous metastases). mRNA for IL-10, a cytokine with anti-inflammatory properties, was detected in 24/25 melanoma metastases and was independent of lymphoid content; in situ the reverse transcriptase/polymerase chain reaction confirmed that melanoma cells were the major source.

271 7553882 We have investigated the role of cytokines (IL-2, IL-3, IL-4, IL-6, IFN-gamma, and GM-CSF) in the generation of primary cytotoxic T lymphocytes (CTL), within a single tumor system.
272 7553882 Most cytokines stimulated nonspecific killers, but IL-2 and IL-3 stimulated primary CTL.
273 7553882 While IFN-gamma alone did not generate primary CTL, coexpression of IFN-gamma with IL-2 resulted in CTL generation.
274 7554398 Iscoms stimulated more secretion of IL-2 and interferon-gamma (IFN-gamma) than the micelles, but both antigenic forms stimulated secretion of IL-4.
275 7554398 DC and B cells pulsed with iscoms stimulated most efficiently the secretion of IL-2 and IFN-gamma.
276 7561146 Interferon-gamma or interleukin-2 are specific and reliable readouts; other cytokines can be measured to further characterize the TH1 and TH2 elements of the T cell responses, although tetanus-stimulated IL-4 production is detected in only a minority of healthy individuals.
277 7571418 More CD4+ than CD8+ gLN T cells were detected by flow cytometric analysis following primary vaginal inoculation and the majority of HSV-specific gLN T cells detected by ELISPOT were CD4+ and Th1-like based on secretion of IFN gamma and not IL-4 or IL-5.
278 7571418 These data suggest that the urogenital cellular immune response elicited in mice following genital inoculation with HSV-2 tk- is predominantly CD4+ and Th1-like, resembling that observed in humans.
279 7589080 CD8+ T cells did not proliferate in vitro even in the presence of the appropriate peptide epitope and exogenous interleukin (IL)-2.
280 7589080 Primed popliteal lymph node cells produced IL-2, IL-5 and interferon (IFN)-gamma, but not IL-4 when restimulated with OVA in vitro.

288 7595213 In addition, T cells purified from the lymph nodes of BALB/c mice immunized with L. donovani or infected with L. major, and from CBA/J mice infected with L. amazonensis were stimulated to proliferate by the recombinant Ldp 23 and produced high levels of IFN-gamma and no IL 4.
289 7612219 Roles for interferon-gamma (IFN-gamma), interleukin 12 (IL-12), and IL-4 in Th1 and Th2 maturation have been demonstrated, although additional undefined signals are required.
290 7614735 In vitro T-cell responses were measured by proliferation and IL2, IFN-gamma, and IL4 release.
291 7620165 We investigated the production of cytokines by highly purified T helper cells from B-cell chronic lymphocytic leukemia (B-CLL) patients stimulated by different activation pathways, and we studied the influence of various accessory cell populations on the pattern of the secretion of cytokines, including interleukin (IL)-2, IL-4, interferon-gamma (IFN-gamma), and IL-10.
292 7620165 Neither a qualitative nor a quantitative difference in cytokine production and proliferative capacity was observed in CLL-derived purified T cells compared with normal individuals, when T cells were stimulated by different pathways, including CD3, CD2, and costimulation with CD28.
293 7620165 CLL cells as aAC caused a marked increase of IL-2, whereas IFN-gamma was only slightly induced and IL-4 was not influenced.

311 7621248 The transduced cells expressed the cytokine gene, secreted biologically active gamma IFN, and exhibited enhanced expression of MHC class I and class II (HLA-DR), and ICAM-1 surface antigens.
312 7621248 Lymphocyte cultures that displayed increases in cytotoxicity after stimulation with the gamma IFN-transduced melanoma cells also exhibited enhanced expression or induction of one or more of the following lymphokines: IL-4, IL-1 alpha, IL-1 beta, gamma IFN, and TNF-alpha.
313 7622110 Like the parental cell line (UCI-107), UCI 107E IL-4 GS cells expressed MHC class I and Her-2/neu surface antigens but did not express detectable MHC class II, ICAM 1, CA 125, or IL-4 receptors.
314 7625646 TH1 cells, which secrete IFN gamma and IL-2, are associated with CMI, rather than humoral responses, and afford protection against intracellular infections including parasites.
315 7625646 In contrast, TH2 cells secrete IL-4, IL-5, and IL-10; elicit high-titer antibody responses and poor CMI; and are associated with susceptibility to infection with intracellular pathogens.

320 7636200 Although not affecting the outcome of primary challenge, serologic ablation of TGF-beta in the former animals abrogated development of acquired resistance and resulted in impaired production of IL-12/IFN-gamma and higher expression of IL-4/IL-10 at the time of reinfection with virulent yeast.
321 7636200 In addition to previous evidence for an obligatory role of IFN-gamma and IL-12 in Candida-driven Th1 cell differentiation in vivo, the present data establish TGF-beta as a third cytokine, the presence of which may be required for optimal Th1 development leading to long-lived anticandidal resistance.
322 7660067 The addition of IL-2, IL-4, and anti-CD40 or anti-CD28 antibodies or the removal of antigen did not restore the B cell response.
323 7678098 CD4+ T-cell clones derived by stimulation with the intact Bb-1 fusion protein were used to identify two T-cell epitopes in the Bb-1A protein, consisting of amino acids SVVLLSAFSGN VWANEAEVSQVVK and FSDVDKTKSTEKT (residues 23 to 46 and 82 to 94).
324 7678098 Biological assays and Northern (RNA) blot analyses for cytokines revealed that following activation with concanavalin A, T-cell clones reactive against the two Bb-1A epitopes produced interleukin-2, gamma interferon, and tumor necrosis factors beta and alpha, but not interleukin-4, suggesting that the Bb-1 antigen preferentially stimulates the Th1 subset of CD4+ T cells in cattle.
325 7679048 The potential of tumor cells (J558L) engineered to produce one of 5 different cytokines (interleukin 2, interleukin 4, interleukin 7, tumor necrosis factor, or gamma-interferon) to give rise to systemic immunity protective against a contralateral challenge with the parental cells was analyzed.
326 7690528 This clone overproduces IL-4 and IL-5, cytokines that promote IgE synthesis.
327 7690528 When these cells are rendered nonresponsive by incubation with a supraoptimal concentration of their allergen peptide determinant, they lose their ability to secrete IL-4 but maintain interferon gamma production.

331 7699320 The current understanding of the function of CD4+ T helper (Th) cells in immunity to infectious diseases is that Th1 cells, which secrete interleukin (IL)-2 and interferon-gamma, induce cellular immune responses, whereas Th2 cells, which secrete IL-4, IL-5, IL-6, and IL-10, provide helper function for humoral immunity.
332 7699320 We have used a panel of poliovirus-specific murine CD4+ T cell clones and mice transgenic for the human poliovirus receptor to evaluate the role of Th cell subpopulations in protective immunity to poliovirus.
333 7699320 The majority of T cell clones, as well as polyclonal T cells generated from mice infected or immunized with poliovirus, secreted IL-2 and interferon-gamma, but not IL-4, IL-5, or IL-10, a profile typical of Th1 cells.

338 7702748 Of the two T-cell subsets (CD4+, CD8+) carrying alpha/beta T-cell receptors, the CD4+ T cells are of major importance for the development of blood stage immunity in both experimental and human malaria.
339 7702748 In some rodent malarias, TH1 cells producing IFN-gamma and IL-2 are important for controlling infection in its early phases, while TH2 cells, producing i.a.
340 7702748 IL-4 and IL-10, together with antibodies, are important for parasite clearance in later phases of infection.

(2) The blunted proliferative response of uraemic CD4 T cells isolated from non-responders and stimulated for 6 days by autologous monocytes presenting HBsAg was associated with the decreased density of the TCR/CD3 receptors. (3) Moreover, in uraemic non-responders the expression of adhesion and accessory molecules on monocytes (intercellular adhesion molecule-1/ICAM-1, HLA-DR/Ia/) was significantly decreased following the culture with autologous monocytes serving as HBsAg-presenting cells.
476 7910675 CD4 molecules and lymphocyte function antigen-1 beta/LFA-1 beta/ on helper-inducer T cells were increased before and after the culture. (4) These findings were also associated with a diminished binding capacity of IL-1 beta and IL-6 to their receptors on helper-inducer T cells. (5) IL-2, IFN-gamma and IL-4 production was decreased in uraemic non-responders, especially after 72 h of the culture. (6) Inhibited proliferation of helper-inducer T cells in uraemic non-responders was only partially reversible in the presence of exogenous IL-1 beta, IL-6, IL-2 and IFN-gamma. (7) HLA typing of uraemic non-responders was associated with extended haplotype: HLA A1,B8,DR3,DR7,DQ2.
477 7911046 It has been shown to be necessary for the T cell independent induction of interferon (IFN)-gamma, critical for the initial suppression of bacterial and parasitic infection; for the development of a Th1 response, critical for effective host defense against intracellular pathogens; and for the activation of differentiated T lymphocytes of both CD4+ and CD8+ phenotype.
478 7911046 In addition to the therapeutic potential associated with IL-12 activity in these disease models, the understanding of its role in immune development and interaction with other cytokines, particularly antagonists, such as IL-4 and IL-10, has clarified and extended our understanding of immune regulation and should lead to significant developments in understanding the progression of AIDS and the development of vaccine adjuvants able to direct the immune response.
479 7929809 We here report the unexpected observations that IL-12 exerts differential effects on the maturation of "native" human CD4 T cells isolated from umbilical cord blood or from the blood of healthy adults.
480 7929809 After priming in the presence of IL-12, naive cells of adult donors, defined as CD45R0- CD4+ T cells, acquire a Th1 phenotype whereas neonatal cells develop into effector cells producing high levels of IL-4 in addition to IFN-gamma.
481 7929809 This effect of IL-12 on neonatal T cells is direct inasmuch as it is observed on highly purified CD4 T cells, however, it is not inhibited by CD8 T cells and natural killer cells.
482 7929809 Given that IL-4 is a potent antagonist of Th1 responses, the finding that IL-12 promotes the maturation of neonatal T cells into IL-4 producers may explain the increased susceptibility of neonates to intracellular pathogens and should be taken into account for the development of vaccines to be used in the perinatal period.

487 7930566 Finally, the inhibitory effect induced by rolipram is independent of its stereochemistry and cannot be exclusively attributed to deficits in IL-2 or IL-4.
488 7930610 Pooled mouse sera were analyzed by ELISA at various times after immunization for IL-1 alpha, IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, IFN-gamma, and TNF-alpha.
489 7930610 In naive mice, vaccine alone induced low levels of IL-3 and IL-5 only; vaccine plus alum induced a low IL-6 response as well.
490 7930610 The MF59-based adjuvants significantly increased the IL-5 and IL-6 levels, whereas Quil A LTC induced strong IFN-gamma and measurable IL-2 responses, in addition to moderate IL-5 and IL-6.
491 7930610 In previously infected mice, MF59 and MF59/MTP-PE were capable of generating IFN-gamma responses, as well as IL-5 and IL-6.
492 7962541 This was associated with an augmented CD8+ cytotoxic T lymphocyte (CTL) activity, increased expression of IFN-gamma mRNA relative to IL-4 mRNA, and a higher titer of RSV-specific IgG2a in the anti-IL-4 treated mice before challenge.
493 7962541 These results suggest that inhibition of IL-4 action at immunization can shift the selective activation of lymphocytes to a more Th1-like response.

597 8056039 Two patterns of cytokine synthesis were induced by TT: (i) T lymphocytes expressed a number of lymphokines (interleukin (IL)-2, IL-3, IL-4, IL-10, interferon (IFN)-gamma and tumor necrosis factor (TNF)-beta), each with distinct kinetics of synthesis.
598 8056039 Cells producing IL-2, IFN-gamma and particularly TNF-beta dominated this in vitro response.

615 8096699 This hypothesis is based on the authors' findings that: (1) progression to AIDS is characterized by loss of IL-2- and IFN-gamma production concomitant with increases in IL-4 and IL-10; and (2) many seronegative, HIV-exposed individuals generate strong TH1-type responses to HIV antigens.
616 8103743 Mycobacteria induce CD4+ T cells that are cytotoxic and display Th1-like cytokine secretion profile: heterogeneity in cytotoxic activity and cytokine secretion levels.

646 8172330 The TH1 cells, which secrete interferon-gamma and interleukin-2 (IL-2), are associated with cell-mediated immunity (CMI), rather than humoral responses, and afford protection against intracellular infections, including those caused by parasites.
647 8172330 In contrast, the TH2 cells secrete IL-4, IL-5, and IL-10, elicit high titer antibody responses, provide poor CMI, and are often correlated with susceptibility to infection.

709 8260457 The mechanisms responsible for differential commitment of effector T cells to the production of either the IL-4/5/10 group or to the IL-2/IFN-gamma group of lymphokines during an immune response have not yet been clearly elucidated.
710 8260457 Intraperitoneal immunization with live bacteria induces an IFN-gamma-dominant immune response associated with a strong DTH reaction and relatively higher levels of specific antibodies belonging to the IFN-gamma-dependent IgG2a isotype rather than the IL-4-dependent IgG1 isotype.
711 8260457 IL-2 production in the responses generated by the two modes of immunization, however, is not preferentially associated with IFN-gamma production, unlike the reported profiles of long-lived murine T cell clones in vitro.

715 8315390 Whereas in vivo administration of ovalbumin (OVA) induces cytokine synthesis that is neither Th1 nor Th2 dominated, administration of glutaraldehyde polymerized, high relative molecular weight OVA (OA-POL) leads to 20-fold increase in the ratio of interferon gamma (IFN-gamma)/IL-4 and IFN-gamma/IL-10 synthesis observed after short-term, antigen-mediated restimulation directly ex vivo.
716 8315390 In contrast, concurrent in vivo administration of anti-IFN-gamma mAb and OVA or OA-POL results in marked increases in IL-4 and IL-10, and decreased IFN-gamma production, reflecting a polarization of the response towards a Th2-like pattern of cytokine synthesis.

719 8326127 Lymphokine assays demonstrated that IL-2 and IL-4 was generally reduced after multiple vaccinations and varied qualitatively as well as quantitatively between mouse strains.
720 8326127 This study substantiates that the five Ag, paramyosin, heat shock protein 70, triosephosphate isomerase, glutathione S-transferase, and the integral membrane protein Sm23, are important candidates for a defined antischistosomal vaccine.
721 8335349 Spleen cells from mice convalescing from a B. pertussis infection exhibited extensive in vitro T-cell proliferation and secreted high levels of interleukin-2 (IL-2) and gamma interferon but not IL-4 or IL-5, a cytokine profile typical of CD4+ Th1 cells.
722 8335349 In contrast, mice immunized with an acellular pertussis vaccine had high levels of B. pertussis antibodies and spleen cells secreting IL-5 but not gamma interferon, a profile characteristic of CD4+ Th2 cells.
723 8345194 In contrast, challenge of mice primed with live RSV by parenteral or mucosal routes induced a Th1-like pattern of cytokine mRNA expression (relative decrease in IL-4 mRNA expression compared to IFN-gamma mRNA expression).
724 8359898 The effects of in vivo administration of monoclonal antibodies against NK-1.1-bearing cells on the early production of gamma interferon (IFN-gamma) in vitro and development of Th1-associated immunity were studied in mice infected with a live vaccine strain of Candida albicans.
725 8359898 In addition, the antibody-treated and infected mice demonstrated unchanged T helper cell responses, as measured by yeast-specific footpad reactions, resistance to reinfection, occurrence of antibodies of different isotypes, and production in vitro of interleukin-2 (IL-2), IFN-gamma, IL-4, and IL-10 by CD4+ cells.
726 8370397 Moreover, several-fold stronger cytokine production, i.e. interleukin (IL)-2, IL-4, IL-5, IL-6, IL-10 and interferon-gamma accompanied the enhanced proliferative response of T cells from CT adjuvant-treated mice.
727 8370397 Phenotypic and functional analyses clearly demonstrated that CT adjuvant primarily enhanced priming of CD4+ rather than CD8+ T cells and the pattern of lymphokine secretion disclosed that CT most probably promoted antigen priming of both Th1 and Th2 type of CD4+ T precursor cells.

746 8470427 Different antigens induced helper T cells with distinct cytokine secretion profiles: some released IL-2, and others predominantly IL-4 and 5.
747 8495971 Monoclonal antibodies to four cytokines were used to find that eosinophilopoiesis was mediated by interleukin-5 (IL-5), whichever the adjuvant, and that IgE production in mice treated with alum was regulated by both IL-4 and IL-5.
748 8495971 The lack of increase in IgE production was not due to suppression by interferon-gamma (IFN-gamma) or by CD8+ T cells.
749 8495971 By the polymerase chain reaction, both IL-4 and IL-5 mRNA were detected in cells from mice given alum, but only IL-5 mRNA was found in cells from mice given CFA.
750 8495971 The dissociation between eosinophilopoiesis and IgE production shown in the mice given CFA could be due to the dissociation between the expression of mRNA of the cytokines IL-4 and IL-5 in vivo.

759 8513449 CD8+ T lymphocytes, purified by fluorescence-activated cell sorting, were cloned directly from the peripheral blood without antigen-presenting cells in the presence of irradiated autologous melanoma cells and recombinant interleukin-2 (IL-2) and IL-4.
760 8513449 Of the 8 clones, 3 expressed both CD4 and CD8, but dual expression was not correlated with specificity of lysis.
761 8513449 Two CD8+ and 2 CD4+ CD8+ clones were specific for the autologous melanoma cells, the other 4 were also reactive against other HLA-A2-positive melanomas.
762 8519092 There was no change in the proportion of PBMC that were CD4+ T cells, CD8+ T cells, NK cells, or B cells as analyzed by flow cytometry.
763 8519092 Analysis for cytokines after vaccination showed spontaneous production of high levels of IL-4 (vaccinees 99 +/- 23; controls 5.6 +/- 5.6 ng/ml, P = 0.031) and TNF alpha (vaccinees 140 +/- 45; controls 42 +/- 14 pg/ml, P = 0.072) accompanied by low levels of IFN-gamma (vaccinees 1.3 +/- 0.6; controls 14.3 +/- 10.1 U/ml), IL-1 alpha (vaccinees 111 +/- 22; controls 442 +/- 107 pg/ml, P = 0.0001), and PGE2 (vaccinees 75 +/- 39; controls 300 +/- 72 pg/ml, P = 0.048).
764 8519092 Increased amounts of IL-4 were also produced after stimulation with PHA (vaccinees 140 +/- 25; controls 40 +/- 40 ng/ml, P = 0.013) while levels of IFN-gamma and soluble IL-2 receptor were similar to controls and levels of IL-1 alpha (vaccinees 443 +/- 67; controls 792 +/- 118 pg/ml, P = 0.026) remained low.
765 8519092 There was no change in the proportion of PBMC that were CD4+ T cells, CD8+ T cells, NK cells, or B cells as analyzed by flow cytometry.
766 8519092 Analysis for cytokines after vaccination showed spontaneous production of high levels of IL-4 (vaccinees 99 +/- 23; controls 5.6 +/- 5.6 ng/ml, P = 0.031) and TNF alpha (vaccinees 140 +/- 45; controls 42 +/- 14 pg/ml, P = 0.072) accompanied by low levels of IFN-gamma (vaccinees 1.3 +/- 0.6; controls 14.3 +/- 10.1 U/ml), IL-1 alpha (vaccinees 111 +/- 22; controls 442 +/- 107 pg/ml, P = 0.0001), and PGE2 (vaccinees 75 +/- 39; controls 300 +/- 72 pg/ml, P = 0.048).

768 8537675 Peripheral blood mononuclear cells (PBMC) from vaccinated infected subjects and vaccinated uninfected controls were evaluated for their ability to produce cytokines characteristic of Th1 or Th2 cells (interferon [IFN]-gamma or interleukin [IL]-4, respectively) after in vitro restimulation with TT.
769 8546393 Cytokine assays of the cell supernatants showed that approximately 100-fold more gamma-interferon than IL-4 was secreted during culture indicating that these vaccines elicited TH1-like responses.
770 8551248 Furthermore, depletion of either CD4+ or CD8+ T cells from tumor-bearing mice before therapy totally suppressed the therapeutic efficacy of DC pulsed with tumor-derived peptides.
771 8551248 The analysis of the cytokine pattern in the draining lymph nodes and spleens of tumor-bearing mice immunized with DC pulsed with tumor-eluted peptides revealed a marked upregulation of interleukin (IL) 4 and interferon (IFN) gamma production, as compared with mice immunized with DC alone or DC pulsed with irrelevant peptides.
772 8551248 DC-induced antitumor effects were completely blocked by coadministration of neutralizing monoclonal antibody directed against T helper cell 1-associated cytokines (such as IL-12, tumor necrosis factor alpha, IFN-gamma), and eventually, but not initially, blocked by anti-mIL-4 mAb.
773 8566039 A proliferative response occurred only late after immunization and the primed T lymphocytes produced interleukin-2, but no interleukin-4.
774 8567952 Antigen presentation by human monocytes was recently found to be enhanced in vitro through the high-affinity Fc receptor for IgG (Fc gamma RI; CD64), which is exclusively present on myeloid cells.
775 8567952 As in humans, expression was properly regulated by the cytokines IFN-gamma, G-CSF, IL-4, and IL-10, and was up-regulated during inflammation.
776 8568254 CD4+ T cells produced IFN-gamma and IL-2 as well as IL-10, but not IL-4 or IL-5.
777 8568254 Although IL-6 was elevated, further purification of cells from in vitro cultures into CD4+ Mac-1- T cells and Mac-1+ CD4- cells revealed that only the latter cell population had consistently elevated IL-6 gene expression, whereas both sorted populations exhibited increased IFN-gamma and IL-10 gene expression.
778 8568254 Our results are consistent with the suggestion that Ag-specific Th1 cells and their derived cytokines, IFN-gamma and IL-2, and Th2-derived IL-10 together with IL-6 produced by macrophages provide important signals for the development of mucosal IgA and serum IgG subclass responses in the absence of preferential expression of Th2 cytokines IL-4 and IL-5.
779 8568254 CD4+ T cells produced IFN-gamma and IL-2 as well as IL-10, but not IL-4 or IL-5.

782 8574153 PBMC from HIV-infected patients (asymptomatic, age 22-36, symptomatic, age 30-59 and pediatric, < 2 years old) were co-cultured with PHA-stimulated PBMC from uninfected individuals in medium containing IL-2 and PAI.
783 8574153 HIV-p24 ag and cytokine profiles (IL-1 beta, IL-2, IL-4, IFN-gamma and TNF-alpha) were determined on supernatants on day 14.
784 8574153 Peripheral blood samples from each patient were evaluated at the beginning of the experiment as to total CD3, total CD19, CD3/CD4, CD3/CD8, CD16/CD56, CD8/HLA-DR and CD8/CD38 markers through flow cytometry.
785 8574153 PAI was able to induce the production of IFN-gamma and TNF-alpha while that of IL-4 and IL-1 beta was reduced.
786 8574153 The predominant cell type detected in the blood samples of the studied subjects were CD8+, CD8+/CD38+ or CD8+/HLA-DR+.

792 8604226 Kinetics of IL-2 and IFN-gamma mRNA expression were comparable in both strains, but IFN-gamma mRNA expression was higher in SJL than in Balb/c.
793 8604226 In addition, studies of IL-12 p4O and IL-10 mRNA expression following immunization with BPO-TT showed a greater IL-12 p4O mRNA expression in Balb/c mice and a slightly higher IL-10 mRNA expression in SJL.
794 8604226 Taken together, our data suggest that Th1 or Th2 differentiation in primary immune responses to haptenic compounds such as penicillin may be driven by the kinetics and the level of IL-4 production rather than by the level of IFN-gamma.
795 8604226 Additional cytokines such as IL-10 and IL-12 are likely to contribute to the regulation of this response.
796 8606065 Lymph node lymphocytes exposed in situ to the immunomodulatory influences of the hormone 1 alpha, 25-dihydroxy vitamin D 3 were found to produce less gamma interferon and interleukin-2 (IL-2) and far more IL-4, IL-5 and IL-10 than lymphocytes from control animals.
797 8611017 On the other hand, oral immunization with rSalmonella expressing Tox C results in Th1-type responses as well as Th2 cell-derived IL-10 and macrophage-derived IL-6, which correlate with mucosal IgA and serum IgG2a antibody responses.
798 8611017 Two major conclusions can be drawn from our studies with these two regimens in normal, IFN-gamma-/-, and IL-4-/- mice.
799 8611017 First, oral administration of rSalmonella, which elicits classical Th1-type responses also induces significant mucosal IgA responses when given to mice with defective Th1- (IFN-gamma-/-) or Th2- (IL-4-/-) cytokine pathways.
800 8611017 Interestingly, we detect Th2-type cells producing IL-10 and macrophage-secreting IL-6 in both normal and cytokine-deficient mice, and we postulate that these two cytokines are of most importance for murine IgA responses.

805 8613355 Oral immunization of interleukin-4 (IL-4) knockout mice with a recombinant Salmonella strain or cholera toxin reveals that CD4+ Th2 cells producing IL-6 and IL-10 are associated with mucosal immunoglobulin A responses.
806 8613355 TT-specific CD4+ T cells from spleen or Peyer's patches produced gamma interferon, indicative of Th1 responses; however, IL-6 and IL-10 were also seen.
807 8613355 Oral immunization of IL-4-/- mice with TT and CT induced weak mucosal IgA to TT; however, brisk IgA anti-CT-B responses and CT-B-specific CD4+ T cells producing IL-6 and IL-10 were also noted.
808 8613355 These result suggest that certain cytokines, i.e., IL-6 and IL-10 from Th2-type cells, play an important compensatory role in the induction and regulation of mucosal IgA responses.

828 8621924 Eradication of pre-established systemic lymphoma was achieved following immunization with lymphoma cells engineered to produce granulocyte-macrophage (GM)-CSF, and to a lesser extent cells producing IL-4, whereas vaccination with lymphoma cells transfected with the genes encoding IL-2 or B7-1 had no effect.

834 8647175 Better knowledge of major histocompatibility complex (MHC)-peptide-T cell receptor (TcR) interactions in the CD4+ T cell response should result in a better design of immunizing peptides and is a prerequisite for the development of vaccines or anti-cytomegalovirus therapy.
835 8647175 CI --> AA substitution induced strong potentiation of HLA-DR8 binding, proliferation and interferon-gamma and interleukin-4 production, possibly due to the removal of negative effects of Cys, Ile, or both side chains.
836 8648120 Immunization of mice with one or two doses of SLAP + IL-12 elicited a dominant population of Ag-specific Th1 lymphocytes in the draining lymph nodes, as judged by the secretion of abundant IFN-gamma but undetectable levels of IL-4, upon antigenic restimulation in vitro.
837 8648120 In contrast, SLAP alone induced a mixed population of Th1 and Th2 cells with secretion of IFN-gamma, IL-4, and IL-10.
838 8648120 The development of a biased Th1 cell population in mice immunized with SLAP + IL-12 was reflected in enhanced levels of Ag-specific IgG2a but decreased levels of IgG1 and total IgE serum Abs.
839 8648120 Ablation of NK1.1+ cells before the administration of a single dose of SLAP + IL-12 reduced Th cell proliferation and almost completely inhibited secretion of IFN-gamma by in vitro-cultured lymph node cells.
840 8648120 Finally, it is demonstrated that the delivery of two doses of SLAP + IL-12 to mice is sufficient to elicit moderate but highly significant levels of protective immunity against challenge infection.

884 8665571 Neither IL-2 nor IFN gamma secretion resulted in the induction of immune T cells.
885 8665571 By contrast, GM-CSF and IL-4 secretion were found to induce immune T cells in the TDLN with GM-CSF being superior to IL-4.
886 8665571 The combined secretion of GM-CSF and IL-4 did not lead to enhanced induction of immune T cells.
887 8665571 Nevertheless, GM-CSF and IL-4 secretion significantly enhanced T cell immune reactivity to the poorly immunogenic BL6 tumor.

1031 8679459 Treatment of established tumours with a single injection of lethally irradiated tumour cells expressing IL-2 + IL-4 was sufficient to either reject tumours, or at least delay further tumour development.
1032 8679459 However, although successful in treatment studies, neither wild-type nor combined IL-2 + IL-4 expressing cells were able to vaccinate animals against a subsequent challenge with live wild-type tumour.
1033 8679459 These results indicate a potential therapeutic benefit with the use of combination IL-2 + IL-4 transduction of autologous cancer cells.

1035 8698391 Cultures of airway leucocytes from C57BL/6 mice produced abundant IFN-gamma whilst those from IFN-gamma R-/- mice produced interleukin-4 (IL-4), IL-5 and IL-10, indicating default to the Th2 pathway; the WT animals showed an intermediate response.
1036 8701598 To clarify the difference in adjuvant effect of these adjuvants, secretion of cytokines, especially interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) which regulate IgE production, was estimated ex vivo.
1037 8701598 Overnight culture of splenic cells obtained from mice immunized with liposomes encapsulating OVA elicits IFN-gamma secretion, but not IL-4 secretion.

1040 8706049 Bacillus Calmette-Guérin plus interleukin-2 and/or granulocyte/macrophage-colony-stimulating factor enhances immunocompetent cell production of interferon-gamma, which inhibits B16F10 melanoma cell growth in vitro.
1041 8706049 Tumor necrosis factor alpha was substantially weaker (IC50 > 10 ng/ml) but provided synergy with IFN gamma.
1042 8706049 None of the other cytokines such as interleukin-2 (IL-2), IL-4, IL-6, IL-10, IL-12, or granulocyte/macrophage-colony-stimulating factor had direct antitumor activity against B16F10 melanoma cells.
1043 8706049 However, when IL-2 and/or GM-CSF were combined with BCG either by exogenous addition or through endogenous production by novel cytokine-secreting recombinant BCG (rBCG), a substantial increase in INF gamma production by splenocytes was observed.
1044 8706049 These results suggest that BCG may exert part of its antitumor action on melanoma through the induction of IFN gamma, which can be greatly enhanced through the concomitant addition of IL-2 and/or GM-CSF.
1045 8709236 These data show that intramuscular inoculation leads to Th1-like responses due to elevated IgG2a levels, production of gamma interferon, CTL activity, and lack of IL-4.
1046 8717406 We have used two delivery systems, soluble tetanus toxoid (TT) with the mucosal adjuvant cholera toxin (CT) and recombinant Salmonella expressing Tox C, a fragment of TT, to assess the nature of CD4+ T helper (Th) cells and derived cytokines which support mucosal IgA responses in both normal and cytokine knockout (interferon gamma knockout; IFN-gamma-/- and IL-4-/-) mice.
1047 8717406 Whereas TT coadministered with CT induces predominant TT-specific Th2-type responses, rSalmonella delivery of Tox C induced dominant Th1-type responses along with synthesis of the Th2-cytokine IL-10.
1048 8717406 Further oral immunization of IFN-gamma-/- and IL-4-/- mice with rSalmonella Tox C also induced macrophage-derived IL-6 and Th2-derived IL-10 as well as S-IgA responses, suggesting that IFN-gamma from Th1-type cells as well as traditional Th2 cells producing IL-4 and IL-5 are not essential for mucosal IgA responses.
1049 8717406 Rather, induction of second level Th2 cells producing IL-10 together with high levels of IL-6 from other cell sources may be sufficient for mucosal IgA responses in the absence of traditional Th2 cells.
1050 8717406 We have used two delivery systems, soluble tetanus toxoid (TT) with the mucosal adjuvant cholera toxin (CT) and recombinant Salmonella expressing Tox C, a fragment of TT, to assess the nature of CD4+ T helper (Th) cells and derived cytokines which support mucosal IgA responses in both normal and cytokine knockout (interferon gamma knockout; IFN-gamma-/- and IL-4-/-) mice.

1054 8733915 Both forms of BHV-1 gD antigen induced good levels of cell-mediated immunity, as evaluated by antigen-specific proliferative response and cytokine (IFN-gamma and IL-4) production.
1055 8742064 To investigate the spectrum of cytokines expressed by peripheral blood mononuclear cells (PBMC) from cynomolgus macaques (Macaca fascicularis), we used a semi-quantitative RT-PCR to determine levels of mRNA coding for IL-1 beta, IL-2, IL-4, IL-6, IL-10, IFN-gamma, and TNF-alpha.
1056 8742064 While transcripts or IL-2, IL-4 and IFN-gamma were either low or not detected in unmanipulated PBMCs, varying levels of IL-1 beta, IL-5, IL-10, and TNF-alpha were readily detected in the same samples.

1059 8778021 The cytokine profiles of B. pertussis-specific T cells in immune animals were determined using antigen-stimulated ex vivo spleen cells or CD4+ T-cell lines and clones established in the presence of interleukin-2 (IL-2) or IL-4.
1060 8778021 However, a proportion of T cells from convalescent mice, especially when cultured in the presence of IL-4, secreted IL-4 and IL-5 with or without detectable IL-2 and interferon-gamma (IFN-gamma), suggesting that Th0 or Th2 cells were also primed during natural infection in vivo.
1061 8778021 Furthermore, when mice were assessed 6 months after infection, spleen cells produced significant levels of IL-4 and IL-5, which were not evident at 6 weeks.

1068 8814247 In the absence of adjuvant, there was an overall reduction in antibody production to OVA in IL-4 -/- mice and significantly greater amounts of interferon (IFN)-gamma were produced following restimulation of splenocytes with antigen in vitro compared with immunocompetent controls (IL-4 +/+).
1069 8814247 Similarly, increased production in vitro by splenocytes of the Th1 cytokine IFN-gamma, equivalent to that produced after inoculation with FCA/OVA, was only detected in IL-4 -/- mice inoculated with alum/OVA.
1070 8814247 However, although production of the Th2 cytokine IL-5 was totally inhibited in IL-4-deficient mice inoculated with FCA/OVA, there was no significant difference in IL-5 production between the two strains when alum was used as adjuvant.

1077 8816812 To determine what barriers the "immunologically privileged" CNS would pose to cytokine-assisted tumor vaccines and what cytokines would be most efficacious against tumors within the CNS, we irradiated B16 murine melanoma cells producing murine interleukin 2 (IL-2), IL-3, IL-4, IL-6, gamma-interferon, or granulocyte-macrophage colony stimulating factor (GM-CSF) and used these cells as subcutaneous vaccines against tumors within the brain.
1078 8816812 Under conditions where untransfected B16 cells had no effect, cells producing IL-3, IL-6, or GM-CSF increased the survival of mice challenged with viable B16 cells in the brain.
1079 8816812 Vaccination with B16 cells producing IL-4 or gamma-interferon had no effect, and vaccination with B16 cells producing IL-2 decreased survival time.
1080 8816812 The response elicited by GM-CSF-producing vaccines was found to be specific to tumor type and to be abrogated by depletion of CD8+ cells.
1081 8816812 Unlike the immunity generated against subcutaneous tumors by GM-CSF, however, the effector responses generated against tumors in the CNS were not dependent on CD4+ cells.

1087 8816970 Interventional approaches that have been successful in delaying insulin-dependent diabetes mellitus (IDDM) using antigen-based immunotherapies include parenteral immunization.
1088 8816970 We have previously shown that immunization with insulin and insulin B chain but not A chain in incomplete Freund's adjuvant (IFA) prevented diabetes by reducing IFN-gamma mRNA in the insulitis lesions.
1089 8816970 When Diphtheria-Tetanus toxoid-Acellular Pertussis (DTP) vaccine was used as the adjuvant vehicle, DTP itself induced significant protection (P < 0.003) which was associated with a Th2-like cytokine producing insulitis profile, IL-4 driven IgG1 antibody responses to insulin, GAD in the periphery and an augmentation of the autoimmune response to GAD.
1090 8839846 Here, we show that the sequential use of early-acting hematopoietic growth factors, stem cell factor, interleukin (IL)-3, and IL-6, followed on day 8 by differentiation in the two-factor combination IL-4 plus granulocytemacrophage colony-stimulating factor (GM-CSF) (CC4GM) is more efficient and allows the cells to be arrested in the LC stage for more than 1 week while continuous maturation occurs in CC7-7.
1091 8839846 LC were CD1a+2 DR+2, CD23+, CD36+, CD80-, CD86-, and CD25-, while DC were CD1a+/- DR+3, CD23-, CD36-, CD80+, CD86+2, and CD25+, CD40 and CD32 were moderately expressed and nearly unchanged on maturation, in contrast to monocyte-derived DC.
1092 8843636 Splenic cells of LC-p467 immunized mice stimulated in vitro with LC-p467 displayed strong proliferative responses and secretion of IL-2, IFN-tau and GM-CSF (but not IL-4 and IL-10) suggesting that immunization with the lipopeptide induced the TH1 type cytokine responses associated with cell-mediated immunity.
1093 8855293 In the 38C13 lymphoma model, we observed that low doses of free granulocyte/macrophage colony-stimulating factor (GM-CSF) 10,000 units i.p. or locally s.c. daily for 4 days significantly enhanced protective antitumor immunity induced by s.c.
1094 8855293 This effect was critically dependent upon effector CD4+ and CD8+ T cells and was not associated with any increased anti-idiotypic antibody production.
1095 8855293 Lymphocytes from spleens and draining lymph nodes of mice primed with Id-KLH plus GM-CSF, but not with Id-KLH alone, demonstrated significant proliferation to Id in vitro without any biased production of interferon gamma or interleukin 4 protein or mRNA.
1096 8861035 Production and specificity of antibodies, cytotoxic responses of macrophages and NK-cells, spontaneous production ex vivo of cytokines IL-1 alpha, IL-2, IL-4, IL-6, IL-10, IFN-gamma, and TNF-alpha in spleen cell cultures in C3H/HeJ (Lps(d)) mice in comparison with C3H/HeN (Lps(n)) mice were tested.
1097 8890192 Accessory function could also be provided by the cytokine interleukin-1 (IL-1), IL-4, or IL-5 but not IL-2 or IL-6.
1098 8892615 We show here that highly purified CD14(bright) peripheral blood monocytes supplemented with granulocyte-monocyte (GM)-CSF plus IL-4 develop with high efficacy (>95% of input cells) into DC.
1099 8892615 They neo-expressed CD1a, CD1b, CD1c, CD80, and CD5; they massively up-regulated CD40 (109-fold) and HLA-DQ and DP (125- and 87-fold); and significantly (>5-fold) up-regulated HLA-DR, CD4, CD11b, CD11c, CD43, CD45, CD45R0, CD54, CD58, and CD59.
1100 8892615 CD14, CD15s, CD64, and CDw65 molecules were down-regulated to background levels, and no major changes were observed for HLA class I, CD11a, CD32, CD33, CD48, CD50, CD86, CDw92, CD93, or CD97.
1101 8892615 Monocytes cultured in parallel with GM-CSF plus TNF-alpha were more heterogeneous in expression densities but otherwise similar in their surface molecule repertoire.
1102 8892615 Only GM-CSF plus IL-4-cultured cells were found to be potent stimulators in allogeneic and autologous MLR and they presented tetanus toxoid 100- to 1000-fold more efficiently than other cell populations tested.

1108 8894351 More recently, cells other than CD4+ T cells, including CD8+ T cells, monocytes, NK cells, B cells, eosinophils, mast cells, basophils, and other cells, have been shown to be capable of producing "Th1" and "Th2" cytokines.
1109 8894351 In this review, we examine the literature on human diseases, using the nomenclature of type 1 (Th1-like) and type 2 (Th2-like) cytokines, which includes all cell types producing these cytokines rather than only CD4+ T cells.
1110 8894351 Type 1 cytokines include interleukin-2 (IL-2), gamma interferon, IL-12 and tumor necrosis factor beta, while type 2 cytokines include IL-4, IL-5, IL-6, IL-10, and IL-13.
1111 8894351 For example, gamma interferon and IL-12 decrease the levels of type 2 cytokines whereas IL-4 and IL-10 decrease the levels of type 1 cytokines.

1116 8898937 The outer surface lipoprotein OspA of Borrelia burgdorferi provides co-stimulatory signals to normal human peripheral CD4+ and CD8+ T lymphocytes.
1117 8898937 Furthermore, incubation of CD2+ T cells or selected CD4+ as well as CD8+ subpopulations with rlip-OspA, but not with rNS1-OspA led to the production of interferon (IFN)-gamma, interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha, but not IL-4.
1118 8898937 In contrast, co-stimulation of the respective T cell populations with anti-CD28 antibodies resulted in the generation of IFN-gamma, IL-4 and TNF-alpha, but not IL-6.
1119 8898937 In light of the fact that inflamed tissues of B. burgdorferi-infected hosts contain blood leukocytes together with spirochetes, their degradation products, or both, these results suggest that infiltrating CD4+ and CD8+ T cells of any specificities, including spirochetes, autoantigens, or both, participate in the pathogenesis of Lyme disease.

1153 8918692 This was accompanied by augmentation of the IRBP-specific IgG1 antibody (Th2) response and down-regulation of the IRBP-specific IgG2a (Th1) response.
1154 8918692 Consistent with this is the observation that two of two T cell lines established from p518-529-primed mice produced Th2-type cytokines (IL-4 and IL-10), whereas three of three T cell lines obtained from IRBP-primed mice produced Th1-type cytokines (IL-2 and IFN-gamma).

1289 9058819 Since tumor Ags can be presented either directly by tumor cells or indirectly by host APC (cross-priming), we asked whether B7.1 and IL-7 or IL-4 complemented each other by improving preferentially one or both pathways of Ag presentation.
1290 9058819 We used TS/A (H-2d) tumor cells and their IL-7, B7, and IL-7/B7 transfectants, and MCA205 (H-2b) tumor cells and their IL-4 and B7 transfectants. beta-galactosidase (beta-gal) was chosen as surrogate tumor Ag. beta-gal has different predominant MHC class I epitopes in H-2d and H-2b mice.
1291 9058819 In conclusion, indirect Ag presentation was augmented by B7, IL-7, and IL-4, while direct Ag presentation was improved only by B7.

1307 9097923 All parameters of T cell activation were normal, including proliferation mediated by CD2, CD3-T cell receptor (TCR) complex, and CD28; acquisition of responsiveness to exogenous IL-2 and IL-4; activation of proteinkinase C (PKC) by phorbol ester and calcium influx by addition of ionomycin.
1308 9100988 We have previously demonstrated that immunization of HIV-1-infected individuals with the common recall antigen, tetanus, induced transient increases in plasma viremia as well as an increased ability to isolate virus from CD8+ T cell-depleted peripheral blood mononuclear cells (PBMCs) under minimally stimulated culture conditions (IL-2 plus IL-4) postimmunization.
1309 9100988 In four of these patients, virus could also be isolated from CD8+ T cell-depleted PBMCs in the presence of tetanus without the addition of any exogenous IL-2.
1310 9100988 HIV-1 was isolated predominantly from CD4+ T cells with a CD45RO+, CD25+ phenotype and was associated with a trend to elevated levels in culture supernatants of IFN-gamma, IL-6, TNF-alpha, and IL-4.

1314 9103465 Cytokine-in-adjuvant steering of the immune response phenotype to HIV-1 vaccine constructs: granulocyte-macrophage colony-stimulating factor and TNF-alpha synergize with IL-12 to enhance induction of cytotoxic T lymphocytes.
1315 9103465 Here we study the effects of IL-2, IL-4, IL-7, IL-1beta, IL-12, IFN-gamma, TNF-alpha, and granulocyte-macrophage CSF (GM-CSF) incorporated with peptide in adjuvant on a variety of responses elicited: CTL, T cell proliferation, cytokine production and message, and Ab isotype.
1316 9103465 GM-CSF synergized with IL-12 for CTL induction in BALB/c mice concomitant with suppression of Th2 cytokines IL-4 and IL-10.
1317 9103465 TNF-alpha also synergized with IL-12, but by a different mechanism, inducing IFN-gamma production in BALB/c mice and thus shifting the response to a Th1 phenotype.
1318 9103465 The results presented here suggest that in addition to IL-2, optimum induction of CD8+ CTL in vivo requires a combination of cytokines, including GM-CSF (probably acting to enhance Ag presentation and CD4+ cell help) and IL-12 (steering the Th response toward Th1 cytokines).

1324 9104786 Peripheral blood mononuclear cells (PBMC) and T cell lines from old and young healthy individuals were therefore analyzed for their production of interferon gamma (IFN-gamma) and interleukin 4 (IL-4).
1325 9104786 When stimulated with TT, PBMC from young and old individuals expressed IL-4, but produced little IFN-gamma.

1340 9109198 On the basis of these findings, a model system for the delivery of vaccine antigens to the immune system in vaccinia, fowlpox or DNA plasmid vectors along with type-2 cytokines, such as interleukin-4 (IL-4), IL-5 and IL-6, as B cell adjuvants is presented.
1341 9122615 The H-2(d) and H-2(k) mice were characterized as low or high responders in respect to the level of specific anti-gp340 antibodies, secretion of IgG2a isotype, antigen-specific lymphoproliferative capacity, interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) production in the basic immunizations with gp340.
1342 9122615 The enhanced antigen-specific secretion of IL-2 and IFN-gamma together with the abrogation of IL-10 and the absence of IL-4 indicates that the responses were driven towards a Th1-type rather than Th2-type immune response.
1343 9125535 In contrast, no increases in interleukin-4 production were observed in the first 24 h and tumor necrosis factor alpha levels increased equally in both nonlethal and lethal infections.
1344 9125535 Infecting mice with increasing numbers of lethal P. yoelii and Plasmodium berghei parasites did not increase the amount of gamma interferon, interleukin-4, and tumor necrosis factor alpha produced in a dose-dependent fashion.

1347 9127013 HIV-1 env DNA vaccine administered to rhesus monkeys elicits MHC class II-restricted CD4+ T helper cells that secrete IFN-gamma and TNF-alpha.
1348 9127013 All of the CD4+ T cell lines responded to Env peptide by secreting IFN-gamma and TNF-alpha without appreciable IL-4 production.
1349 9127013 Demonstration of a nucleotide vaccine eliciting a Th1-like immune response is consistent with the well documented ability of naked DNA vaccines to induce durable CD8+ CTL responses.
1350 9129542 Interleukin-2 (IL-2), IL-4, IL-13, and interferon-gamma were selected as lymphokine mRNAs of interest, since expression of these cytokines helps define the type of T helper lymphocyte response (i.e., TH1 versus TH2).
1351 9129542 Finally, partial sequences of owl monkey coding regions for IL-2, IL-13, and interferon-gamma were determined and compared for homology with their human counterparts.
1352 9140097 Thus, ovalbumin (OVA) iscoms induced higher levels of antigen-specific IgG1 and IgG2a antibodies and increased the production of both IFN-gamma and IL-4 compared with OVA administered without adjuvant.
1353 9140097 In contrast, OVA formulated in Al(OH)3 elicited IgG1 and IgE antibodies and primed spleen cells producing IL-4 and IL-10, suggesting the activation of primarily Th2-like cells.

1356 9140115 Two cytokine genes, granulocyte-macrophage colony-stimulating factor and interleukin-4, were introduced into glioma cells by sequential transduction with two single-expression GK vectors.
1357 9144226 Both S61F and native CT enhanced the induction of ovalbumin-specific CD4(+) T cells in lung and splenic tissues, and these T cells produced a Th2-type cytokine pattern of interleukin 4 (IL-4), IL-5, IL-6, and IL-10 as determined by analysis of secreted proteins and by quantitation of cytokine-specific mRNA.
1358 9151790 Although treatment with antibody against IL-4 or recombinant IL-12 (rIL-12) at the time of formalin-inactivated RSV vaccination induced a similar shift in the pattern of cytokine mRNA expression upon live virus challenge, anti-IL-4 treated mice had increased CD8+ cytotoxic T lymphocyte activity and reduced illness compared with rIL-12-treated mice.
1359 9151790 To define effector mechanisms responsible for these patterns, CD4+ and/or CD8+ T lymphocytes were selectively depleted in vivo at the time of RSV challenge.
1360 9151790 In rIL-12-treated mice, CD4+ lymphocytes made the largest contribution to IFN-gamma mRNA, RSV clearance, and illness, while in anti-IL-4 treated mice, CD8+ lymphocytes were the major effector.

1365 9164952 Rhesus macaques were orally immunized with a mucosal vaccine consisting of two different concentrations (1 mg vs 250 microg) of recombinant SIV p55gag (p55) with or without cholera toxin (CT, 50 microg) as a mucosal adjuvant.
1366 9164952 When culture supernatants from these p55-stimulated PBMCs were examined for Th1 (IFN-gamma) and Th2 (IL-4 and IL-10) cytokines, both IFN-gamma and IL-10 were present, but IL-4 was absent.
1367 9164952 CD4+ T cells isolated from these p55-stimulated PBMCs contained IFN-gamma spot-forming cells (SFCs) but not IL-4 SFCs.
1368 9164952 These results were further confirmed by cytokine-specific reverse transcriptase PCR analysis, where p55-specific CD4+ T cells expressed mRNA for IFN-gamma, IL-6, and IL-10, but not IL-4.
1369 9164952 These findings suggest that oral immunization of nonhuman primates induced both IFN-gamma-secreting Th1 and select Th2 cytokine (e.g., IL-6 and IL-10)-producing CD4+ Th cells, which accounted for the generation of p55-specific systemic and mucosal Ab responses.

1380 9169747 Antigen-stimulated PBMC of responsive wP recipients were characterized by an elevated production of T-helper-cell type 1 cytokines gamma interferon (IFN-gamma) and interleukin 2 (IL-2), low to minimal production of IL-5, and no production of IL-4.
1381 9169747 The PBMC of aP vaccine-responsive recipients showed, in addition to the elevated IFN-gamma production, a consistent, antigen-dependent production of type 2 cytokines (IL-4 and IL-5), with PRN being the most and PT being the least effective antigen.
1382 9169747 Type 2 cytokine induction was more pronounced in aP-SB than in aP-CB recipients, as shown by the presence of IL-4 mRNA transcripts and higher IL-5 production in the former (161.6 +/- 36 and 47.9 +/- 44 pg/ml [mean +/- standard error for five subjects each], respectively, after PRN stimulation).

1389 9178456 The pattern of expression of interleukin-4 (IL-4) and interferon-7 (IFN-gamma 1 mRNA was established by day 4 after challenge and was maintained at least through day 12, and was not affected by the concentration of priming immunogen or virus challenge.
1390 9178456 An enzyme-linked immunospot assay demonstrated that CD4+ T cells were responsible for the production of IL-4, while many cell types secreted IFN-gamma.
1391 9178456 These experiments begin to define the kinetics of cytokine expression and phenotypes of cytokine-producing cells following RSV infection, supporting previous findings that suggested aberrant infiltration of CD4+ T lymphocytes and excessive IL-4 secretion may play a role in the vaccine-enhanced disease associated with RSV.

1398 9178643 Both the ratio of IL-4:IFN-gamma-secreting cells and the isotype of antibodies produced by these mice were altered by primary immunization.
1399 9184629 These CSF cell populations consist of approximately 60% CD4+ T-cells, half of which bear IL-2 receptors, indicating these activated T-cells may be part of the pathogenic process in MS.
1400 9184629 When these activated CD4+ T-cells were selectively expanded in IL-2/IL-4 supplemented cultures, an over-representation of several TCRV beta families was noted in 39/47 patients, the most frequent being V beta 6.5, V beta 6.7, V beta 2, V beta 5 and V beta 4.
1401 9190958 Analysis of IFN-gamma and IL-4 production by CD4+ T cell clones obtained from cultures stimulated with anti-CD3 mAb or the env peptides showed an increased proportion of Th2 and Th0 clones in HIV-infected children with lower HIV-specific CTL activity, whereas children with high CTL activity had increased numbers of Th1 clones.
1402 9191335 Modulation of bovine T cell responses by IL-12 and the influence of IL-4 on interferon-gamma responses to respiratory syncytial virus.
1403 9191837 We also examined the influence of MV infection on the production of the cytokines IL-4, IL-6, IL-10, and IFN-gamma by T lymphocytes.
1404 9191837 By comparing infected versus uninfected antigen-specific T cell lines, we found that MV infection of antigen-specific activated T cells caused no substantial change in generation of IFN-gamma, IL-6, or IL-10.
1405 9199462 A murine model of pneumonia due to the mouse pneumonitis agent (MoPn [murine Chlamydia trachomatis]) in mice deficient in CD4+ T-cell function (major histocompatibility complex [MHC] class II function [class II-/-], CD8+ T-cell function (beta2-microglobulin deficient, MHC class I deficient [Beta2m-/-]), B-cell function (C57BL/10J-Igh(tm1Cgn) [Igh-/-]), and gamma interferon (IFN-gamma) (C57BL/6-Ifg(tm1) [Ifg-/-]) or interleukin-4 (C57BL/6J(tm1Cgn29) [IL4-/-]) production was employed to determine if each of these mechanisms was critical to resistance against reinfection by C. trachomatis or if alternate compensatory mechanisms existed in their absence which could potentially be exploited in vaccine development.
1406 9199462 CD4 T-cell-deficient MHC class II-/- mice were very susceptible to reinfection with MoPn, showing the critical importance of this cell to resistance.
1407 9199462 These mice lacked antibody production but did produce IFN-gamma, apparently by mechanisms involving NK and CD8+ T cells.
1408 9199462 Levels of lung IFN-gamma and TNF-alpha were elevated in Igh-/- mice compared to those in controls.
1409 9199462 Of most importance, however, congenitally IFN-gamma-deficient Ifg-/- mice (which have elevated levels of other cytokines, including TNF-alpha and granulocyte-macrophage colony-stimulating factor) are paradoxically more resistant to MoPn rechallenge than controls, showing that IFN-gamma is not an absolute requirement for acquired resistance and implying the presence of very effective compensatory host defense mechanism(s).
1410 9199462 Thus, resistance to reinfection in this model is flexible and multifactorial and is heavily dependent on CD4+ T cells, with a probable role for IFN-gamma and TNF-alpha and a possible modest role for Th1-dependent antibody.
1411 9199462 Since IFN-gamma was dispensable in host defense, the highly effective mechanism or mechanisms which can compensate for its absence (which include TNF-alpha) deserve further study.
1412 9200470 Analysis of intracellular cytokines by flow cytometry showed that IFN-gamma production during challenge was increased, and IL-4 and IL-5 levels were reduced by IL-12 treatment.
1413 9203655 Compared with responses in placebo recipients, vaccinees had greater postvaccination H3(Beijing/32) HA (H3)-specific lymphoproliferation and interleukin (IL)-2, IL-10, and interferon-gamma (IFN-gamma) production.
1414 9203655 Mean increases in the production of IL-10 (> or = 20-fold) and IL-2 (10-fold) were relatively greater than that of IFN-gamma (4-fold) or IL-4 (no change).
1415 9203655 Serum H3 antibodies were induced in 80% of rHA recipients, and the rise in antibody titer was significantly correlated with changes in IL-2, IL-10, and IFN-gamma concentrations.

1459 9234539 Mice immunized with gp120 DNA developed strong antigen-specific antibody responses, CD8+ cytotoxic T lymphocytes (CTL) (following in vitro restimulation with gp120-derived peptide), and showed in vitro proliferation and Th1-like cytokine secretion [gamma-interferon, interleukin (IL)-2 with little or no IL-4] by lymphocytes obtained from all lymphatic compartments tested (spleen, blood, and inguinal, iliac, and mesenteric lymph nodes).
1460 9234766 Analysis of cytokine production revealed mRNA for Th1-type cytokines (interleukin 2 [IL-2] and gamma interferon) as well as Th2-type cytokines (IL-4 and IL-10) in the spleens of both protected and susceptible animals.
1461 9257854 However, in vitro restimulation of the accompanying virus-specific T cell populations from the two sites did not reveal any significant difference in lymphokine output, and isotype expression was not altered substantially in mice lacking IL-4 or IL-6 genes.
1462 9261953 After a single subcutaneous injection, iscoms were delivered to the draining LN where they induced a transient population of LN cells which responded with proliferation and secretion of interleukin-2 (IL-2), gamma-interferon (IFN-gamma) and interleukin-4 (IL-4) after restimulation.
1463 9261953 The response in the spleen developed more slowly, sustained for 12 weeks and was characterized by cells producing in particular IL-2 and IFN-gamma but also IL-4.

1466 9272363 In an investigation of cell-mediated immunity against Bordetella pertussis, we found that B. pertussis infection in infants and in mice was associated with the induction of antigen-specific T cells that secrete IFN-g and IL-2, but not IL-4 or IL-5.
1467 9272363 An examination of cytokine production following immunization with a three-component acellular vaccine, comprising inactive PT, FHA and pertactin adsorbed to alum, demonstrated that spleen cells from vaccinated mice produced high levels of IL-5, but no detectable IFN-g and low levels of IL-2.

1470 9278182 In addition, we have shown that whereas IL-2 and interferon-gamma production is dramatically impaired by the drug, IL-4 production is not significantly altered.
1471 9286367 The originally developed culture system to generate DC from peripheral human blood with GM-CSF and IL-4 was dependent on the use of fetal calf serum.

1492 9341744 Detection of CD4+CD45RO+ T lymphocytes producing IL-4 in response to antigens on Plasmodium falciparum erythrocytes: an in vitro correlate of protective immunity induced with attenuated Plasmodium falciparum sporozoites.
1493 9341744 We have previously reported that although considered stage specific based on antibody and CD8+ cytolytic T lymphocyte responses directed against preerythrocytic stage antigens, in particular, the circumsporozoite protein and sporozoite surface protein 2, protective immunity induced in humans by attenuated Plasmodium falciparum SPZ may also involve CD4+ T cell responding to antigens present on parasitized red blood cells (pRBC).

1555 9384286 Cellular activation induced by Mycobacterium bovis bacillus Calmette-Guérin (BCG) and heat shock proteins (HSP) leads to the production of proinflammatory cytokines such as interleukin-1beta (IL-1beta) and IL-6.

1599 9393799 Gamma interferon (IFN-gamma) production driven by LSA1 peptides ranged from 34 to more than 3,500 pg/2 x 10(6) cells, was derived primarily from CD8+ cells, and was dissociated from T-cell proliferation.
1600 9393799 In contrast to proliferation and IFN-gamma, interleukin 4 (IL-4) and/or IL-5 responses to LSA1 peptides were detected in only 18% of the subjects.
1601 9393799 The dominance of type 1 CD8 cell IFN-gamma responses is consistent with a role for this T-cell population in immunity to liver-stage Plasmodium falciparum in humans.
1602 9394185 CD4+ and CD8+ T1 cells, through the agency of IL-2 and IFN-gamma, direct the response towards cell-mediated immunity involving cytotoxicity and macrophage activation, whereas T2 cells, through the agency of IL-4 and IL-10, direct the response towards antibody production.
1603 9394185 The two poles are counter-regulatory in that IFN-gamma inhibits antibody formation and IL-4 and IL-10 inhibit macrophage activation.
1604 9394185 However, immune responses are not immutable and can be artificially driven towards one or other pole, for example IFN-gamma, IL-2 and IL-12 favour T1 responses, whereas IL-4 and IL-10 favour the T2 type.
1605 9394185 For example, in experimental leishmaniasis, protective immune responses can be induced by the incorporation of genes for IL-2 and IFN-gamma into recombinant Salmonella typhimurium vectors and nucleic acid vaccines.

1614 9398398 IL-12 and IL-10 were selectively or preferentially expressed by the regressor mice, and this correlated with the detection of functional type 1 reactivity in vivo (i.e., delayed-type hypersensitivity).
1615 9398398 Other cytokines were produced by the regressor mice only in vitro (IFN-gamma) or were not detected at all with either type of tumor recipient (IL-4).
1616 9399949 We used an animal model, experimental myasthenia gravis induced in C57Bl/6 mice by immunization with Torpedo acetylcholine receptor (TAChR), to demonstrate that nasal administration of synthetic sequences of the TAChR alpha-subunit- forming epitopes recognized by anti-TAChR CD4+ T helper cells (residues alpha150-169, alpha181-200, and alpha360-378), given before and during immunization with TAChR, causes decreased CD4+ responsiveness to those epitopes and to TAChR, reduced synthesis of anti-TAChR Ab, and prevented experimental myasthenia gravis.
1617 9399949 Secretion of IL-2, IL-4, and IL-10 by spleen T cells from TAChR immunized mice, in response to challenge with TAChR in vitro, indicated that in sham-tolerized mice only Th1 cells responded to TAChR, while peptide-treated mice had also an AChR-specific Th2 response.
1618 9400611 Hantavirus pulmonary syndrome: CD8+ and CD4+ cytotoxic T lymphocytes to epitopes on Sin Nombre virus nucleocapsid protein isolated during acute illness.
1619 9400611 We isolated a CD8+ cytotoxic T lymphocyte (CTL) clone directly from the blood of a patient with the acute hantavirus pulmonary syndrome (HPS) which recognizes a SNV specific epitope on the virus nucleocapsid protein (aa 234-242) that is restricted by HLA C7 and produces IFN gamma but not IL-4.
1620 9400611 We identified a second CD8+ CTL epitope located within another site aa 131-139 on the nucleocapsid protein, which is HLA B35 restricted, and a CD4+ CTL epitope located on a third site on nucleocapsid protein aa 372-380 using lymphocytes obtained during HPS from another patient that were stimulated in vitro.
1621 9400611 Hantavirus specific CD8+ and CD4+ CTL may contribute to the immunopathology and capillary leak syndrome observed in the HPS.

1623 9414288 In this report, we question whether CD86 (B7.2) or the cytokines granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-4 (IL-4), or tumor necrosis factor-alpha (TNF-alpha) can improve the vaccination potential of AML cells.
1624 9414288 Our studies show that (1) mice vaccinated with a leukemogenic number of AML cells engineered to express B7.2 (B7.2-AML) or to secrete GM-CSF, IL-4, or TNF-alpha (GM-, IL-4-, TNF-alpha-AML) do not develop leukemia; (2) GM-AML cells are tumorigenic in sublethally irradiated SJL/J mice but not in Swiss nu/nu mice, indicating that killing of tumor cells is not T-cell-dependent; (3) vaccines with irradiated GM-AML, but not B7.2-, IL-4-, or TNF-alpha-AML cells, can elicit leukemia-specific protective and therapeutic immunity; and (4) in head-to-head comparison experiments, vaccination with irradiated GM-AML is more potent than B7.1-AML, curing 80% and providing 20% prolonged survival of the leukemic mice at week 2, as opposed to cures only up to 1 week with B7.1-AML vaccines.

1628 9419445 Immunization of BALB/c mice with bone marrow-derived dendritic cells (DC) generated in the presence of GM-CSF/IL-4 and prepulsed with the H-2Kd-binding wild-type p53(232-240) peptide has been shown to induce anti-peptide CTL.
1629 9423854 During infection or after immunization, CD4+/CD8- and CD8+/CD4- hsp65-reactive T cells increased equally in spleens.
1630 9423854 During infection, the majority of these cells were weakly CD44 positive (CD44(lo)) and produced interleukin 4 (IL-4) whereas after immunization the majority were highly CD44 positive (CD44(hi)) and produced gamma interferon (IFN-gamma).
1631 9423854 When the cells were separated into CD4+/CD8- and CD8+/CD4- types and then into CD44(hi) and CD44(lo) types, CD44(lo) cells were essentially unable to transfer protection, the most protective CD44(hi) cells were CD8+/CD4-, and those from immunized mice were much more protective than those from infected mice.
1632 9423854 Thus, whereas the CD44(lo) IL-4-producing phenotype prevailed during infection, protection was associated with the CD8+/CD44(hi) IFN-gamma-producing phenotype that predominated after immunization.

1726 9551367 Autologous peripheral blood dendritic cells (DCs), which were easily generated from all donors when cultured in the presence of recombinant human interleukin-4 and recombinant human granulocyte-macrophage colony-stimulating factor were pulsed with melanoma peptides and used to "prime" and/or "boost" CTL cultures in vitro.

1787 9643372 Because polysaccharides of the bacterial cell wall stimulate TNF-alpha production by monocyte-macrophages and TNF-alpha was shown to stimulate HIV replication directly on activation of NF-kappa b after binding the long terminal repeat (LTR) sequences of HIV, we measured TNF-alpha production and observed a significant increase in both groups of vaccines.
1788 9643387 Th 1 type helper cells that produce type 1 class cytokines, such as interferon gamma and interleukin-2 (IL-2), are known to be important in cellular immunity to Legionella as well as to other opportunistic intracellular bacteria.
1789 9643387 In contrast, Th 2 type helper cells, which secrete type 2 class cytokines such as IL-4, IL-5, and IL-6, activate B lymphocytes to produce humoral antibodies important in resistance to extracellular bacteria which secrete toxins and extracellular factors as compared to intracellular bacteria such as Legionella.
1790 9645357 Rather, P splenocytes produce two-to threefold higher amounts of IL-4 and IL-10, cytokines which down-regulate the cytotoxic potential of IFN-gamma-treated macrophages.

1847 9686195 Elevated levels of IL-12 (p40 mRNA) were detected in the lymph nodes (LN) and the lungs of vaccinated mice, whilst treatment of vaccinated mice with anti-IL-12 antibodies decreased the ratio of IFN gamma:IL-4 secreted by in vitro-cultured LN cells.
1848 9686195 Soluble antigens from the lung-stage of the parasite (SLAP) appeared to be efficient stimulators of IFN gamma and IL-12 secretion.
1849 9686195 These antigens when used to immunise mice in conjunction with IL-12 as an adjuvant, elicited a polarised Th1 response with abundant IFN gamma secretion but no IL-4.
1850 9686195 The induction of a dominant Th1 response using SLAP + IL-12 probably operates via IFN gamma production by natural killer (NK) cells stimulated by IL-12, since in vivo ablation of NK cells using anti-NK1.1 antibody reduced CD4(+)-dependent IFN gamma production from cultured LN cells by over 97%.
1851 9686195 Nevertheless, in mice with a genetic disruption of the IFN gamma receptor, administration of SLAP + IL-12 induced levels of IFN gamma equal to those in wild-type mice, thus showing that in this model IL-12 can directly prime T cells independent of IFN gamma.

1894 9717833 Analysis of the specificity and restriction of the cytokine responses to G89 by G89-stimulated T cells revealed that these cells secreted significantly higher levels of IFN-gamma than interleukin 4 and interleukin 10, suggesting priming for a Th0-T helper 1 response.
1895 9723654 Studies in peripheral blood and within the target organ have demonstrated a shift in the balance of T-cell subsets away from TH2-type (producing particularly IL-4 and IL-5) in favor of a TH1-type T-lymphocyte response (with the preferential production of IFN-gamma).
1896 9724877 Mice deficient in gamma-delta T cells, classical major histocompatibility complex class I, non-classical antigen presentation pathways, the cytokines interferon-gamma, interleukin-4, interleukin-6 and the cytolytic effector molecules perforin or FasL were completely immune to secondary infection.
1897 9725246 Both groups produced significant levels of IL-4 and IL-5.

1899 9741428 CD4 T lymphocytes from gp63-pcDNA-3-immunized mice proliferated and produced IFN-gamma (but not IL-4) when stimulated in vitro with freeze-thawed parasites, consistent with a Th1 immune response.
1900 9741428 In contrast, lymphocyte proliferation in animals immunized with freeze-thawed parasites was associated with IL-4 (but not IFN-gamma) production, suggesting a nonprotective Th2 response.
1901 9741428 CD4 T lymphocytes from gp63-pcDNA-3-immunized mice proliferated and produced IFN-gamma (but not IL-4) when stimulated in vitro with freeze-thawed parasites, consistent with a Th1 immune response.
1902 9741428 In contrast, lymphocyte proliferation in animals immunized with freeze-thawed parasites was associated with IL-4 (but not IFN-gamma) production, suggesting a nonprotective Th2 response.
1903 9743368 L-selectin(low/-) T cells exhibited tumor-specific cytokine release that was type 2 (IL-4, IL-10) following vaccination with native D5 and type 1 (IFN-gamma) following vaccination with gene-modified D5-Kd.
1904 9754570 Cultured lymph node cells from KO mice had markedly altered cytokine profiles with significantly decreased production of IFN-gamma increased IL-4.
1905 9754570 After challenge, cells recovered from the lungs of KO mice secreted abundant IL-4 and IL-5 but little IFN-gamma, while flow cytometric and histological analysis of lung cell populations recorded a very high proportion of eosinophils.

1910 9756643 The MBP-selected line could likewise be rendered unresponsive by incubation with supraoptimal concentrations of immunodominant peptide and anergy induction was accompanied by IL-10 release.
1911 9767429 Restimulated immune lymphoid cells showed enhanced production of both IL-2 and interferon-gamma and reduced secretion of IL-4.
1912 9767601 Antigen-stimulated production of the Th1 cytokine IFN-gamma by splenocytes increased progressively up to 14 weeks post infection, (four weeks after the onset of parasite egg production), before declining swiftly.
1913 9767601 Levels of the Th2 cytokine IL-4 in the same cultures remained low until 14 weeks, after which they rose rapidly as IFN-gamma declined.
1914 9767601 High levels of IL-10 coincided with the peak in IFN-gamma production, suggesting a non Th2-restricted role for this cytokine.
1915 9776139 IFN-gamma, TNF-alpha, IL-4 and IL-10 were evaluated in the PFMC supernatants stimulated by these antigens.
1916 9776139 Both crude and 70-kDa antigens induced higher levels of IFN-gamma, TNF-alpha and IL-10.

1922 9780187 Neutralization of IL-12 activity at the time of HKL administration blocked the enhancement of IFN-gamma and reduction of IL-4 production, indicating that IL-12, induced by HKL, was responsible for the adjuvant effects on cytokine production.
1923 9780187 Moreover, administration of KLH with HKL as an adjuvant reversed established immune responses dominated by the production of Th2 cytokines and high levels of KLH-specific IgE and induced a Th1-type response with high levels of IFN-gamma and IgG2a and low levels of IgE and IL-4.

1926 9784552 Analysis of the cytokines expressed by the Th cells revealed that all clones expressed gamma interferon and tumor necrosis factor alpha, and most coexpressed interleukin-4.
1927 9789195 In order to improve upon preclinical tumor vaccine strategies that employ dendritic cells (DC), we now have compared short-term cultures of spleen- and GM-CSF/IL-4-stimulated bone marrow (BM) to determine if differences exist in phenotype and function of murine DC derived from primary and secondary hematolymphoid organs.
1928 9795387 The MF59 induced higher levels of serum IL-4 and IL-5 cytokines, suggesting a more Th2 type of response.
1929 9811500 The cytokine secretion profiles of the T cells consisted of high levels of interferon-gamma with undetectable levels of interleukin-4 and interleukin-10.
1930 9811500 Moreover, incorporation of MPLA in the MUC1 peptide-loaded PLGA microspheres resulted in an increase in interferon-gamma production.
1931 9811501 The cytokine profiles showed significant production of interferon-gamma (IFN-gamma, a Th1-type cytokine) and extremely low levels of interleukin-4 (IL-4, a Th2-type cytokine).
1932 9811501 The control group of C57BL/6 mice immunized with peptide plus alum showed a very low level of T cell proliferation, and no increase was seen in IFN-gamma or IL-4 production.

1935 9824496 Determination of cytokine co-expression in individual splenic CD4+ and CD8+ T cells from influenza virus-immune mice.
1936 9824496 We have studied the patterns of interleukin-2 (IL-2), IL-4 and interferon-gamma (IFN-gamma) co-expression displayed by individual splenic CD4+ and CD8+ T cells in response to influenza virus immunization.
1937 9824496 The frequencies of CD4+ and CD8+ T cells expressing IL-2, IL-4 and IFN-gamma were determined by three-colour flow cytometric analysis of fixed and saponin-permeabilized cells fluorescent-stained for either CD4 or CD8 surface molecules and for one of the following combinations of two intracellular cytokines: IL-2/IL-4, IL-2/IFN-gamma and IL-4/IFN-gamma.
1938 9824496 The results showed that immunization with influenza virus induces in both CD4+ and CD8+ T cells a heterogeneity of cytokine response patterns that do not follow the type 1/type 2 polarized response model, but with substantial differences between the two populations.
1939 9824496 IL-4/IL-2, IL-4/IFN-gamma and IL-2/IFN-gamma), whereas immune CD4+ T cells were seen to express almost exclusively a single cytokine per cell.
1940 9824496 The observed patterns of cytokine production suggest that influenza virus immunization induces the expression of a type 0 cytokine pattern at both population and single cell levels in CD8+ T cells and exclusively at the population level in CD4+ T cells.

1942 9824496 We have studied the patterns of interleukin-2 (IL-2), IL-4 and interferon-gamma (IFN-gamma) co-expression displayed by individual splenic CD4+ and CD8+ T cells in response to influenza virus immunization.
1943 9824496 The frequencies of CD4+ and CD8+ T cells expressing IL-2, IL-4 and IFN-gamma were determined by three-colour flow cytometric analysis of fixed and saponin-permeabilized cells fluorescent-stained for either CD4 or CD8 surface molecules and for one of the following combinations of two intracellular cytokines: IL-2/IL-4, IL-2/IFN-gamma and IL-4/IFN-gamma.
1944 9824496 The results showed that immunization with influenza virus induces in both CD4+ and CD8+ T cells a heterogeneity of cytokine response patterns that do not follow the type 1/type 2 polarized response model, but with substantial differences between the two populations.
1945 9824496 IL-4/IL-2, IL-4/IFN-gamma and IL-2/IFN-gamma), whereas immune CD4+ T cells were seen to express almost exclusively a single cytokine per cell.

1953 9829733 High enrichment of CD34+ HSCs was obtained using an immunomagnetic bead cell separation device.
1954 9829733 After separation, the negative fraction of mobilized PBMCs from normal donors and cancer patients contained undetectable levels of CD34+ HSCs by flow cytometry.
1955 9829733 This fraction of cells was then subjected to plastic adherence, and the adherent cells were cultured for 7 days in GM-CSF (100 ng/ml) and interleukin 4 (50 ng/ml) followed by an additional 7 days in GM-CSF, interleukin 4, and tumor necrosis factor alpha (10 ng/ml) to generate DCs.
1956 9829733 Harvested DCs represented yields of 4.1+/-1.4 and 5.8+/-5.4% of the initial cells plated from the CD34+ cell-depleted mobilized PBMCs of normal donors and cancer patients, respectively, and displayed a high level expression of CD80, CD86, HLA-DR, and CD11c but not CD14.
1957 9829733 Collectively, these results demonstrate the feasibility of obtaining both DCs and CD34+ HSCs from the same leukapheresis collection from G-CSF-primed normal donors and cancer patients in sufficient numbers for the purpose of combined PBSCT and immunization strategies.
1958 9834103 LeIF: a recombinant Leishmania protein that induces an IL-12-mediated Th1 cytokine profile.
1959 9834103 When lymph node cells from infected BALB/c mice were stimulated in vitro with LeIF, only IFN-gamma (and no detectable IL-4) was found in the culture supernatant.
1960 9834103 We found that LeIF stimulated fresh spleen cells from naive SCID mice to secrete IFN-gamma by IL-12/IL-18-dependent mechanisms.
1961 9847356 To investigate whether the Th1- or Th2-type immune responses are more important for protection from HSV-2 infection, we codelivered the DNA expression construct encoding the HSV-2 gD protein with the gene plasmids encoding the Th1-type (interleukin-2 [IL-2], IL-12, IL-15, and IL-18) and Th2-type (IL-4 and IL-10) cytokines in an effort to drive immunity induced by vaccination.
1962 9851359 The CTLs were cross-reactive against multiple strains of type A influenza viruses and produced IFNgamma but no IL-4.
1963 9862710 Immunologic analysis of Ab isotype during infection and splenocyte IFN-gamma, IL-2, and IL-4 production following stimulation with Leishmania Ag or Con A indicates that there was a significant shift from a predominantly Th2-associated immune response in mice infected with wild-type L. mexicana to a Th1-associated response in mice inoculated with delta cpb or delta cpa/cpb.
1964 9862872 After in vitro stimulation with HBsAg, peripheral blood mononuclear cells (PBMC) of only 1 of 5 acute and 1 of 6 chronic HBV patients, but of all 6 vaccine recipients, secreted varying amounts of interferon gamma (IFN-gamma), but no interleukin-4 (IL-4) or IL-5.
1965 9862872 Furthermore, the addition of IFN-gamma, but not of IL-2, -4, -12, or IFN-alpha, resulted in strong increases of anti-HBs-secreting B cells in vaccine recipients and chronic carriers.
1966 9864210 Previous studies demonstrated that cattle immunized with native protein that were subsequently protected against challenge had a strong IFN-gamma and weaker interleukin-4 (IL-4) response in immune lymph node lymphocytes that reflected the cytokine profile of the majority of CD4(+) T-cell clones obtained from peripheral blood.
1967 9864210 RAP-1-specific T helper (Th) cell clones that coexpress IFN-gamma and IL-4 are typical of numerous parasite-specific clones examined.
1968 9864210 The capacity to enhance IgG2 production was associated with production of IFN-gamma by Th cells cocultured with B cells, antigen, and IL-2.
1969 9864210 Previous studies demonstrated that cattle immunized with native protein that were subsequently protected against challenge had a strong IFN-gamma and weaker interleukin-4 (IL-4) response in immune lymph node lymphocytes that reflected the cytokine profile of the majority of CD4(+) T-cell clones obtained from peripheral blood.
1970 9864210 RAP-1-specific T helper (Th) cell clones that coexpress IFN-gamma and IL-4 are typical of numerous parasite-specific clones examined.
1971 9864210 The capacity to enhance IgG2 production was associated with production of IFN-gamma by Th cells cocultured with B cells, antigen, and IL-2.
1972 9865740 To characterize the antibody (Ab) response against a known antigen, colon carcinoma C26 cells and C26 variants engineered to produce interleukin (IL) 12 or IL-4 were further transduced to express the human tumor-associated antigen gp38 folate receptor (FR) alpha.
1973 9865740 Irradiated IL-12- and IL-4-producing C26/FR alpha cell vaccines cured 50 and 30% of mice bearing C26/FR alpha lung micrometastases.
1974 9865740 Treatment induced a rapid, CD4-dependent Ab production dominated by IgG2a and IgG1 in response to the IL-12 or IL-4 vaccine, respectively.
1975 9865740 Sera from mice cured by the IL-12 vaccine displayed a higher binding activity, a higher anti-FR alpha IgG2a content, and a higher complement-mediated tumor cell lysis in vitro compared to the sera from nonresponder mice.
1976 9865740 To characterize the antibody (Ab) response against a known antigen, colon carcinoma C26 cells and C26 variants engineered to produce interleukin (IL) 12 or IL-4 were further transduced to express the human tumor-associated antigen gp38 folate receptor (FR) alpha.
1977 9865740 Irradiated IL-12- and IL-4-producing C26/FR alpha cell vaccines cured 50 and 30% of mice bearing C26/FR alpha lung micrometastases.
1978 9865740 Treatment induced a rapid, CD4-dependent Ab production dominated by IgG2a and IgG1 in response to the IL-12 or IL-4 vaccine, respectively.
1979 9865740 Sera from mice cured by the IL-12 vaccine displayed a higher binding activity, a higher anti-FR alpha IgG2a content, and a higher complement-mediated tumor cell lysis in vitro compared to the sera from nonresponder mice.
1980 9865740 To characterize the antibody (Ab) response against a known antigen, colon carcinoma C26 cells and C26 variants engineered to produce interleukin (IL) 12 or IL-4 were further transduced to express the human tumor-associated antigen gp38 folate receptor (FR) alpha.
1981 9865740 Irradiated IL-12- and IL-4-producing C26/FR alpha cell vaccines cured 50 and 30% of mice bearing C26/FR alpha lung micrometastases.
1982 9865740 Treatment induced a rapid, CD4-dependent Ab production dominated by IgG2a and IgG1 in response to the IL-12 or IL-4 vaccine, respectively.
1983 9865740 Sera from mice cured by the IL-12 vaccine displayed a higher binding activity, a higher anti-FR alpha IgG2a content, and a higher complement-mediated tumor cell lysis in vitro compared to the sera from nonresponder mice.
1984 9865738 The induction of in vivo proliferation of long-lived CD44hi CD8+ T cells after the injection of tumor cells expressing IFN-alpha1 into syngeneic mice.
1985 9865738 The injection of viable cells producing IFN-alpha or IL-12 caused a marked proliferation of CD8+ T lymphocytes in both the spleen and lymph nodes.
1986 9865738 In contrast, proliferation of CD8+ T cells did not occur in mice injected with control cells or with cells expressing IL-4, granulocyte colony-stimulating factor, or IFN-gamma.
1987 9865738 Pulse-chase studies in mice injected with IFN-alpha-producing cells showed that a proportion of proliferating CD8+ T cells survived for at least 70 days, suggesting that long-lived memory cells are induced using such an approach.
1988 9878011 Immunohistochemical staining was used to enumerate cytokine-producing cells (monokines: interleukin [IL]-1alpha, IL-1beta, IL-6, and tumor necrosis factor [TNF]-alpha; lymphokines: interferon-gamma, IL-2, IL-4, and TNF-beta) in tissues obtained at autopsy from subjects with HPS.
1989 9878081 Since autoimmune responses to glutamic acid decarboxylase (GAD) are up-regulated in insulin-dependent diabetes mellitus (IDDM), in this study GAD67-specific antibody, T cell proliferation and lymphokine production patterns were analysed in the adjuvant-treated mice to characterize the regulatory mechanisms underlying the protection.
1990 9878081 Upon in vitro stimulation with GAD67, draining lymph node and spleen cells from CFA-immunized NOD mice or syngeneic islet-grafted and BCG-protected NOD mice produced much more IL-4, whereas there was no significant change in IFN-gamma production.
1991 9886376 CT inhibited IL-12-induced IFN-gamma secretion both in vivo and in vitro.
1992 9886376 This shift of the CT-induced immune response toward Th1 type was associated with TT-specific CD4+ T cells secreting IFN-gamma and reduced levels of Th2-type cytokines (i.e., IL-4, IL-5, IL-6, and IL-10).
1993 9886376 IFN-gamma secretion by TT-specific CD4+ T cells was also enhanced; however, Th2-type cytokine responses were predominant.
1994 9886377 We addressed the effects of two cytokines, IL-6 and IL-12, derived from APCs, for the development of mucosal IgA Ab responses following their nasal delivery with the protein vaccine tetanus toxoid (TT).
1995 9886377 Coadministration of IL-6 and IL-12 with TT did not enhance the mucosal or serum Ab responses over those seen with IL-12 alone.
1996 9886377 TT-specific CD4+ T cells from mice given TT with IL-6 or IL-12 produced higher levels of IFN-gamma, IL-6, and IL-10 than did those from control mice, but only negligible levels of IL-4 and IL-5.
1997 9886377 In summary, both intranasal IL-6 and IL-12 induced serum Abs that protected mice from systemic challenge with TT, whereas only IL-12 induced mucosal S-IgA Ab responses.
1998 9886383 BmDC cultured under various conditions (granulocyte-macrophage CSF (GM-CSF) or GM-CSF plus IL-4 alone or in combination with Flt3 ligand, TNF-alpha, LPS, or CD40 ligand (CD40L)) were analyzed morphologically, phenotypically, and functionally and were tested for their ability to promote prophylactic and/or therapeutic antitumor immunity.
1999 9886383 Whereas cells cultured in GM-CSF alone were functionally immature, cells incubated with CD40L or LPS were mature BmDC, as evident by morphology, capacity to internalize Ag, migration into regional lymph nodes, IL-12 secretion, and alloantigen or peptide Ag presentation in vitro.
2000 9924700 Eleven of the 26 patients tested had evidence of an anti-STn TH1 antigen-specific T-cell response as determined by interferon-gamma, but not interleukin (IL)-4, production.
2001 9973457 Mucosally induced systemic T cell unresponsiveness to ovalbumin requires CD40 ligand-CD40 interactions.
2002 9973457 CD40 ligand (CD40L) gene-disrupted (CD40L-/-) mice were employed to examine the role of costimulatory signals via CD40L-CD40 interactions in mucosally induced tolerance.
2003 9973457 Further, cytokine analysis of splenic CD4+ T cells showed that both Th1-type (e.g., IFN-gamma and IL-2) and Th2-type (e.g., IL-4, IL-5, IL-6, and IL-10) responses were maintained in CD40L-/- mice orally immunized with OVA, whereas these cytokine responses in CD40L+/+ mice were significantly reduced.
2004 9973457 In addition, splenic CD4+ T cells from CD40L-/- mice orally immunized with OVA provided B cell help in Ag-specific Ab-forming cells when the cells were cultured with naive B cells in the presence of Ag and CD40L-transfected cell lines.
2005 9973457 In contrast, an identical culture condition containing splenic CD4+ T cells from orally tolerized CD40L+/+ mice did not exhibit helper activity.
2006 9973457 Taken together, these findings indicate that CD40L and CD40 interactions are essential for the induction of systemic T cell unresponsiveness to orally administered Ag.
2007 9973465 Lymphotactin (Lptn) is a C chemokine produced predominantly by NK and CD8-positive (CD8+) T cells including gammadelta TCR-positive (TCR+) intraepithelial lymphocytes.
2008 9973465 CD4-positive (CD4+) T cells isolated from mucosal compartments and spleens of mice intranasally immunized with OVA plus Lptn displayed higher OVA-specific proliferative responses and greater synthesis of IFN-gamma, IL-2, IL-4, IL-5, IL-6, and IL-10 than did CD4+ T cells from mice given OVA without Lptn.
2009 9987172 Spleen cells from BALB/c mice immunized intramuscularly with this vaccine were stimulated to secrete IFN gamma and IL-4 when exposed to PA in vitro.

2052 9988446 Mononuclear cell cytokine responses to house-dust mite were measured at 6-monthly intervals from birth to 2 years of age, using ELISA (IL-10, IL-13, IFN-gamma) and sqRT/PCR (IL-4, IL-5, IL-9, IFN-gamma) in normal infants (n = 14) with no family history or allergic symptoms, and infants with a family history and definite atopy by 2 years (n = 16).
2053 10037196 Here, we demonstrate that functional DCs can be generated from peripheral blood of patients with metastatic renal cell carcinoma (RCC) by culture of monocytes/macrophages (CD14+) in autologous serum containing medium (RPMI) in the presence of granulocyte macrophage colony-stimulating factor and interleukin (IL) 4.
2054 10037196 A synergistic effect of DC-TuLy and IL-2 in stimulating a T cell-dependent immune response was demonstrated by: (a) the increase of growth expansion of TILs (9.4-14.3-fold; day 21); (b) the up-regulation of the CD3+ CD56- TcR+ (both CD4+ and CD8+) cell population; (c) the augmentation of T cell-restricted autologous tumor lysis; and (d) the enhancement of IFN-gamma, tumor necrosis factor-alpha, granulocyte macrophage colony-stimulating factor, and IL-6 mRNA expression by TILs.
2055 10048771 To further engineer the immune response in vivo, we investigated the induction and regulation of immune responses from the codelivery of Thl cytokines (interleukin-2 [IL-2] and IL-12), Th2 cytokines (IL-4 and IL-10), and granulocyte-macrophage colony-stimulating factor (GM-CSF) genes along with a DNA vaccine construct encoding for simian immunodeficiency virus (SIV) gag/pol proteins.
2056 10048771 We observed that coinjection with IL-2, IL-4, IL-10, and GM-CSF resulted in increased levels of antigen-specific antibodies.
2057 10048771 We also observed that coadministration of IL-2, IL-12, and GM-CSF genes resulted in a dramatic enhancement of Th proliferation responses.
2058 10048771 To further engineer the immune response in vivo, we investigated the induction and regulation of immune responses from the codelivery of Thl cytokines (interleukin-2 [IL-2] and IL-12), Th2 cytokines (IL-4 and IL-10), and granulocyte-macrophage colony-stimulating factor (GM-CSF) genes along with a DNA vaccine construct encoding for simian immunodeficiency virus (SIV) gag/pol proteins.

2060 10048771 We also observed that coadministration of IL-2, IL-12, and GM-CSF genes resulted in a dramatic enhancement of Th proliferation responses.
2061 10067692 Restimulated immune lymphoid cells from mice which received both agents showed enhanced production of interferon-gamma (IFN-gamma) and reduced secretion of IL-4.
2062 10067692 However, administration of DNA vaccine with IL-15 and IL-2 or IL-12 expression plasmids did not alter the effect of IL-15 expression plasmid on the DNA vaccine.
2063 10067692 These results indicate that intranasal administration of DNA vaccine and IL-15 expression plasmid is capable of enhancing the T helper type 1 (Th1) dependent HIV-1-specific cell-mediated immunity, and that the IL-15 and IL-2 or IL-12 expression plasmids may not have a synergistic effect on the immune response induced by DNA vaccine in vivo.
2064 10072509 IL-4 plays a clear role as an inhibitor of CD4+ Th1 cells; however, its role in CD8+ T cell regulation appears to be more complex.
2065 10072509 Thus, IL-4 may augment CD8+ T cell growth, but also limit effector function.
2066 10072509 This report investigates these disparate roles of IL-4 in CD8+ T lymphocyte regulation by comparing T cell responses specific for a single HIV-IIIIB gp120-derived epitope in BALB/c mice deficient in IL-4 to those in wild-type controls.
2067 10072509 Secretion of IL-2 and IFN-gamma by CD8+ T cells from IL-4-deficient mice was also elevated, reflecting their enhanced activation.
2068 10072509 Thus, IL-4 appears to limit the activation, expansion, and differentiation of CD8+ T cells with high cytolytic potential.
2069 10072509 IL-4 plays a clear role as an inhibitor of CD4+ Th1 cells; however, its role in CD8+ T cell regulation appears to be more complex.

2078 10072509 Thus, IL-4 appears to limit the activation, expansion, and differentiation of CD8+ T cells with high cytolytic potential.
2079 10072509 IL-4 plays a clear role as an inhibitor of CD4+ Th1 cells; however, its role in CD8+ T cell regulation appears to be more complex.
2080 10072509 Thus, IL-4 may augment CD8+ T cell growth, but also limit effector function.

2089 10072541 IL-12 gene as a DNA vaccine adjuvant in a herpes mouse model: IL-12 enhances Th1-type CD4+ T cell-mediated protective immunity against herpes simplex virus-2 challenge.
2090 10072541 In contrast, Th cell proliferative responses and secretion of cytokines (IL-2 and IFN-gamma) and chemokines (RANTES and macrophage inflammatory protein-1alpha) were significantly increased by IL-12 coinjection.
2091 10072541 However, the production of cytokines (IL-4 and IL-10) and chemokine (MCP-1) was inhibited by IL-12 coinjection.
2092 10072541 Thus, IL-12 cDNA as a DNA vaccine adjuvant drives Ag-specific Th1 type CD4+ T cell responses that result in reduced HSV-2-derived morbidity as well as mortality.
2093 10073728 In order to determine the effects of various cytokines on long-term protection against the influenza virus, mice were intramuscularly coinoculated with plasmids that encoded either the granulocyte-macrophage colony-stimulating factor (GMCSF), interleukin-4 (IL-4), interleukin-12 (IL-12), or the interleukin-6 (IL-6) gene, in the presence of two plasmids that encoded the nucleoprotein (NP) and the hemagglutinin (HA) gene of the influenza A virus.
2094 10073728 The coadministration of IL-4, IL-6 and IL-12 transiently enhanced antibody responses against influenza virus in early time points (4 to 7 week post immunization) after post inoculation.
2095 10073728 Mice that received either the IL-12 or the IL-6 gene had enhanced NP-specific CTL responses.

2098 10073728 Mice that received either the IL-12 or the IL-6 gene had enhanced NP-specific CTL responses.
2099 10074183 Antigen-specific gamma interferon (IFN-gamma) T-helper (type 1-like) responses were detected in the DNA-immunized group, but only after the fourth immunization, and the rgp120/MF59 group generated both IFN-gamma and interleukin-4 (IL-4) (type 2-like) responses that appeared after the third immunization.
2100 10074183 In contrast, rgp120/ISCOM-immunized animals rapidly developed marked IL-2, IFN-gamma (type 1-like), and IL-4 responses that peaked after the second immunization.
2101 10074183 Antigen-specific gamma interferon (IFN-gamma) T-helper (type 1-like) responses were detected in the DNA-immunized group, but only after the fourth immunization, and the rgp120/MF59 group generated both IFN-gamma and interleukin-4 (IL-4) (type 2-like) responses that appeared after the third immunization.

2103 10077215 We observed enhanced cytotoxic T-lymphocyte activity accompanied by increased secretion of IL-6, IFNgamma and GM-CSF.
2104 10077215 Enhanced IFNgamma but unchanged IL-4 secretion suggested a T-helper 1-mediated anti-tumor immune response.
2105 10078605 Mice infected with recombinant S. typhimurium had elevated IFN-gamma levels over non-recombinant S. typhimurium and placebo controls. but IL-4 and IL-5 levels were low and did not differ significantly between these groups.
2106 10087178 Antigen-specific and polyclonally induced T cell responses were analyzed in 10 HIV-infected individuals and in 14 controls by enumerating the numbers of tetanus toxoid (TT)-specific and phytohemagglutinin (PHA)-induced IFN-gamma-secreting cells (SC) and IL-4-SC using an enzyme-linked immunospot assay.
2107 10087178 Cell depletion experiments indicated that this difference was related to an impairment of CD4(+) T-cell-mediated TT-specific IFN-gamma secretion.
2108 10191208 The role of interleukin (IL)-2 and IL-4 in herpes simplex virus type 1 ocular replication and eye disease.
2109 10191208 To assess the relative effect of interleukin (IL)-2- and IL-4-dependent immune responses on herpes simplex virus (HSV)-1 infection, naive, vaccinated, and mock-vaccinated IL-20/0 and IL-40/0 knockout mice were challenged ocularly with HSV-1.
2110 10191208 Recombinant (r) IL-2 treatment of the IL-20/0 mice significantly reduced ocular HSV-1 replications, but rIL-4 treatment of IL-40/0 mice significantly increased ocular HSV-1 replications.
2111 10191208 Th1 (IL-2) cytokine responses may help protect mice against ocular HSV-1 challenge and reduce ocular HSV-1 replication.

2122 10195637 A novel influenza subunit vaccine composed of liposome-encapsulated haemagglutinin/neuraminidase and IL-2 or GM-CSF.
2123 10195637 This study was aimed at analyzing, in parallel, the humoral and cellular immune responses elicited in mice immunized with liposomal influenza A (Shangdong/9/93) subunit vaccines composed of haemagglutinin/neuraminidase (H3N2) and IL-2 or GM-CSF.
2124 10195637 The main findings were: (a) the combined liposomal vaccines consisting of encapsulated antigen and encapsulated cytokine, but not the free antigen, elicited a high titer of serum IgG1, IgG2a, IgG3 and IgM antibodies; (b) the combined liposomal vaccines were efficient following administration by the various routes, and induced a local (in lung) IgA response in i.n. vaccinated mice; (c) the liposomal vaccines triggered DTH and cytotoxic responses, as well as cytokine (mainly IL-4) production.
2125 10201894 We show that CD4 T cells are readily activated and produce IL-2, IFN-gamma and IL-4, characteristics of an uncommitted phenotype.
2126 10203054 If Ag-specific IFN-gamma and/or IL-4 as well as lymphoproliferative (LP) responses were found with the lack of a detectable IL-2 response, then protection was not observed.
2127 10209035 Hapten-specific, colonic patch T cells from both mouse groups exhibited a Th2 phenotype with interleukin (IL)-4 and IL-5 production.
2128 10209035 TNBS colitis in normal mice treated with anti-IL-4 antibodies or in IL-4(-/-) mice was less severe than in either IFN-gamma+/+ or IFN-gamma-/- mice.
2129 10209035 Hapten-specific, colonic patch T cells from both mouse groups exhibited a Th2 phenotype with interleukin (IL)-4 and IL-5 production.
2130 10209035 TNBS colitis in normal mice treated with anti-IL-4 antibodies or in IL-4(-/-) mice was less severe than in either IFN-gamma+/+ or IFN-gamma-/- mice.
2131 10211787 Using flow cytometric detection methods we observe alterations of the intracellular cytokines IFN-gamma, IL-2, and IL-4 at the single-cell level during the course of immunization.
2132 10211787 There was a strong increase of intracellular IFN-gamma and IL-2 characteristic for a Th1 cell type immune response after treatment with ACA125.
2133 10216760 Six nucleic acids distinguished between IL3 and IL4, three of which were predicted to be expressed as amino acids.
2134 10225917 Marked expression of gamma interferon mRNA was detected in the stomach of all protected mice, and 50% of these mice expressed interleukin 4 (IL-4) or IL-5 mRNA.
2135 10228040 These noncytolytic CD4+ T cells synthesize large quantities of type 2 cytokines such as IL-4 and IL-10 on stimulation with the autologous APC or tumor cells in an MHC class II-restricted manner.
2136 10228040 The supernatant factor also exhibits a marked inhibitory effect on the expression of the costimulatory molecules, CD80 and CD86, by APC.
2137 10228044 Addition of IL-2 or IL-7, but not IL-4 or IL-12, also restored proliferation of acute PBMC stimulated with anti-CD3.
2138 10233736 While IL-2 and interferon-gamma (IFN-gamma) levels did not differ significantly between the two groups, the level of IL-4 was found to be lower in the group given rBCG/IL-2.
2139 10233736 This resulted in a strong interferon-gamma:IL-4 ratio, suggesting a skewing of the immune response towards a Type 1 response.
2140 10233736 While IL-2 and interferon-gamma (IFN-gamma) levels did not differ significantly between the two groups, the level of IL-4 was found to be lower in the group given rBCG/IL-2.
2141 10233736 This resulted in a strong interferon-gamma:IL-4 ratio, suggesting a skewing of the immune response towards a Type 1 response.
2142 10233743 In a murine model, we analysed the in vitro effects of granulocyte-macrophage colony-stimulating factor (GM-CSF) alone or combined with interleukin-4 (IL-4) or Flt3 ligand (Flt3-L) on the number, immunophenotype and functions of bone marrow-derived DC.
2143 10233743 In GM-CSF cultures, we have identified two populations based on their level of expression of major histocompatibility complex (MHC) class II molecules: MHC-IIhi cells, exhibiting the typical morphology and immunophenotype of myeloid DC (CD11c+ 33D1+ DEC-205+ F4/80+), and MHC-IIlo cells, heterogeneous for DC markers (30% CD11c+; 50% 33D1+; DEC-205-; F4/80+).
2144 10233743 In contrast, after addition of IL-4 to GM-CSF, the two populations displayed a very similar phenotype (CD11c+ 33D1- DEC-205+ F4/80-), differing only in their expression levels of MHC class II and costimulatory molecules, and showed similar stimulatory activity in mixed leucocyte reaction.
2145 10233743 In a murine model, we analysed the in vitro effects of granulocyte-macrophage colony-stimulating factor (GM-CSF) alone or combined with interleukin-4 (IL-4) or Flt3 ligand (Flt3-L) on the number, immunophenotype and functions of bone marrow-derived DC.
2146 10233743 In GM-CSF cultures, we have identified two populations based on their level of expression of major histocompatibility complex (MHC) class II molecules: MHC-IIhi cells, exhibiting the typical morphology and immunophenotype of myeloid DC (CD11c+ 33D1+ DEC-205+ F4/80+), and MHC-IIlo cells, heterogeneous for DC markers (30% CD11c+; 50% 33D1+; DEC-205-; F4/80+).
2147 10233743 In contrast, after addition of IL-4 to GM-CSF, the two populations displayed a very similar phenotype (CD11c+ 33D1- DEC-205+ F4/80-), differing only in their expression levels of MHC class II and costimulatory molecules, and showed similar stimulatory activity in mixed leucocyte reaction.
2148 10233752 In the present study, we were able to detect by Elispot analysis high frequencies of immunoglobulin G (IgG)-secreting B cells and mitogen-responsive interferon-gamma (IFN-gamma) or interleukin-4 (IL-4)-secreting T cells in peritoneum and spleen of human/BALB/c chimeric mice during the first 3 weeks after PBMC transfer.
2149 10233752 High numbers of TT-specific IFN-gamma-secreting T cells persisted in the peritoneum of vaccinated, but not of unvaccinated, animals during the entire observation period, but only low numbers of specific IL-4-secreting T cells were found in vaccinated mice.
2150 10233752 In the present study, we were able to detect by Elispot analysis high frequencies of immunoglobulin G (IgG)-secreting B cells and mitogen-responsive interferon-gamma (IFN-gamma) or interleukin-4 (IL-4)-secreting T cells in peritoneum and spleen of human/BALB/c chimeric mice during the first 3 weeks after PBMC transfer.
2151 10233752 High numbers of TT-specific IFN-gamma-secreting T cells persisted in the peritoneum of vaccinated, but not of unvaccinated, animals during the entire observation period, but only low numbers of specific IL-4-secreting T cells were found in vaccinated mice.
2152 10321955 Interestingly, though gamma-interferon (gammaIfn) and IL-10 were both secreted in response to stimulation by NS3 antigen, IL-2 was not.
2153 10321955 Lack of IL-2 induction was confirmed by a failure to amplify IL-2 mRNA upon NS3 antigen stimulation, whereas IL-4, IL-15, and gammaIfn mRNA were seen as early as 24 h.
2154 10321955 The predominance of IL-4 and IL-10 and the lack of IL-2 suggests that in vitro responses to at least some HCV antigens are biased towards a Th2 phenotype, which may be conducive to viral persistence.
2155 10321955 Interestingly, though gamma-interferon (gammaIfn) and IL-10 were both secreted in response to stimulation by NS3 antigen, IL-2 was not.
2156 10321955 Lack of IL-2 induction was confirmed by a failure to amplify IL-2 mRNA upon NS3 antigen stimulation, whereas IL-4, IL-15, and gammaIfn mRNA were seen as early as 24 h.
2157 10321955 The predominance of IL-4 and IL-10 and the lack of IL-2 suggests that in vitro responses to at least some HCV antigens are biased towards a Th2 phenotype, which may be conducive to viral persistence.
2158 10352290 The vaginal B cell response could further be enhanced by using the Th2-type cytokines IL-4 or IL-5 as genetic adjuvants concomitantly with the DNA vaccine before intranasal booster immunization with the recombinant vaccine.
2159 10359214 This response was augmented following the pretreatment of KS-CD80 cells with interferon-gamma and tumor necrosis factor-alpha.
2160 10359214 Interleukin-4 (IL-4), IL-7, and IL-12 further increased T-cell expansion.
2161 10361131 We found that mixtures of irradiated cells expressing granulocyte-macrophage colony-stimulating factor (GM-CSF) plus those expressing interleukin-4 (IL-4) or tumor necrosis factor alpha (TNFalpha) protected mice against WEHI-3B-induced leukemias.
2162 10361131 When bone marrow mononuclear cells (BMMNCs) obtained from mice that had been injected with irradiated, cytokine-expressing tumor cells were injected into tumor-bearing mice, the survival of the latter was significantly prolonged; the longest survival was observed in mice receiving BMMNCs containing an increased number of DCs from animals injected with a mixture of tumor cells expressing GM-CSF with those expressing IL-4.
2163 10361131 We found that mixtures of irradiated cells expressing granulocyte-macrophage colony-stimulating factor (GM-CSF) plus those expressing interleukin-4 (IL-4) or tumor necrosis factor alpha (TNFalpha) protected mice against WEHI-3B-induced leukemias.
2164 10361131 When bone marrow mononuclear cells (BMMNCs) obtained from mice that had been injected with irradiated, cytokine-expressing tumor cells were injected into tumor-bearing mice, the survival of the latter was significantly prolonged; the longest survival was observed in mice receiving BMMNCs containing an increased number of DCs from animals injected with a mixture of tumor cells expressing GM-CSF with those expressing IL-4.
2165 10367950 However, both synthetic genes induced an equally strong and more pronounced Th2 response with higher IgG1/IgG2a and IFNgamma/IL-4 ratios than the wt.gp160 gene.
2166 10382757 Another important pre-erythrocytic malaria antigen, the thrombospondin-related adhesive protein (TRAP), can induce protection in animal models of malaria, but knowledge of human T cell responses is limited to the identification of CD8 T cell epitopes, with no CD4 epitopes identified to date.
2167 10382757 A total of 50 naturally exposed Gambian adults were assessed to define 26 T cell epitopes in PfTRAP capable of inducing rapid IFN-gamma or IL-4 production, as assessed by enzyme-linked immunospot assays.
2168 10383946 Antigen-specific lympho-proliferative responses in vitro were reduced by 65% in the pretreated group; IL-5 and IL-4, but not IFN-gamma, production were markedly decreased in responder cells of lungs and spleens of nasally pretreated mice.
2169 10383946 In contrast, mucosal administration of rBet v 1-CTB conjugates prior to sensitization led to an up-regulation of allergen-specific IgE, IgG1 and IgG2a, increased in vitro lympho-proliferative responses as well as augmented production of IL-5, IL-4, IL-10 and IFN-gamma.
2170 10383946 Antigen-specific lympho-proliferative responses in vitro were reduced by 65% in the pretreated group; IL-5 and IL-4, but not IFN-gamma, production were markedly decreased in responder cells of lungs and spleens of nasally pretreated mice.
2171 10383946 In contrast, mucosal administration of rBet v 1-CTB conjugates prior to sensitization led to an up-regulation of allergen-specific IgE, IgG1 and IgG2a, increased in vitro lympho-proliferative responses as well as augmented production of IL-5, IL-4, IL-10 and IFN-gamma.
2172 10384115 A model for CD8+ CTL tumor immunosurveillance and regulation of tumor escape by CD4 T cells through an effect on quality of CTL.
2173 10384115 Regression was dependent on CD8 T cells, and recurrent tumors were resistant to CTL, had substantially reduced expression of epitope mRNA, but retained the gp160 gene, MHC, and processing apparatus.
2174 10384115 Unexpectedly, CD4 cell depletion protected mice from tumor recurrence, whereas IL-4 knockout mice, deficient in Th2 cells, did not show this protection, and IFN-gamma knockout mice were more susceptible.
2175 10384115 Purified CD8 T cells from CD4-depleted mice following tumor regression had more IFN-gamma mRNA and lysed tumor cells without stimulation ex vivo, in contrast to CD4-intact mice.
2176 10384115 Thus, the quality as well as quantity of CD8+ CTL determines the completeness of immunosurveillance and is controlled by CD4 T cells but not solely Th2 cytokines.
2177 10389910 CTLs recognizing the HLA-A2.1-restricted, wild-type sequence p53 epitopes p53(149-157) and p53(264-272) were generated from CD8-enriched populations of nonadherent peripheral blood lymphocytes (PBLs) obtained from healthy donors.
2178 10389910 The PBLs were restimulated in vitro with peptide-pulsed granulocyte macrophage colony-stimulating factor- and interleukin (IL)-4-induced autologous dendritic cells in the presence of IL-6 and IL-12 and subsequently cultivated with IL-1alpha, IL-2, IL-4, IL-6, and IL-7.
2179 10392620 Splenic lymphocytes from mice immunized with replicons alone, or replicons plus recombinant ureB produced abundant interferon-gamma and no detectable interleukin-4 upon stimulation with recombinant ureB.
2180 10395689 We have addressed this central issue by using the radiation-attenuated cercariae vaccine in mice genetically engineered to exhibit highly polarized type 1 (IL-10/IL-4-deficient) or type 2 (IL-10/IL-12-deficient) cytokine and Ab phenotypes.
2181 10395689 This immunity in IL-10-deficient mice correlated with higher parasite-specific Ab titers, greater proliferative capacity of lymphocytes, increased frequency of IFN-gamma- and IL-4-secreting cells, elevated perivascular/peribronchial inflammatory responses in the lung, and greater in vitro schistosomulacidal capacity of parasite Ag-elicited cells.
2182 10395689 We have addressed this central issue by using the radiation-attenuated cercariae vaccine in mice genetically engineered to exhibit highly polarized type 1 (IL-10/IL-4-deficient) or type 2 (IL-10/IL-12-deficient) cytokine and Ab phenotypes.
2183 10395689 This immunity in IL-10-deficient mice correlated with higher parasite-specific Ab titers, greater proliferative capacity of lymphocytes, increased frequency of IFN-gamma- and IL-4-secreting cells, elevated perivascular/peribronchial inflammatory responses in the lung, and greater in vitro schistosomulacidal capacity of parasite Ag-elicited cells.
2184 10395703 Production of IFN-gamma, IL-3, and IL-5 by liver cells was also markedly reduced after i.n. treatment of CTB-Sm28GST, whereas IL-4 production was not impaired.
2185 10403923 Both Th1 and Th2 cytokines (interferon-gamma (IFN-gamma) and IL-4) were lower in the spleens of the DNA-immunized animals compared with the protein-Ribi-immunized animals, possibly suggesting a different level of helper T cell response to the two different modes of immunization.
2186 10411548 Mice expressing lymphocytic choriomeningitis virus nucleoprotein (LCMV-NP) as a transgene in their beta cells develop insulin-dependent diabetes mellitus (IDDM) only after LCMV infection.
2187 10411548 Inoculation of plasmid DNA encoding the insulin B chain reduced the incidence of IDDM by 50% in this model.
2188 10411548 The insulin B-chain DNA vaccination was effective through induction of regulatory CD4 lymphocytes that react with the insulin B chain, secrete IL-4, and locally reduce activity of LCMV-NP-autoreactive cytotoxic T lymphocytes in the pancreatic draining lymph node.
2189 10413189 Serum has been analyzed for IgE, specific titers to Rubella vaccine, sCD25 (the soluble form of the IL2 receptor), sCD27 (the soluble form of the lymphocyte specific member of the tumor necrosis factor receptor family), and IL4 (the cytokine interleukin 4).
2190 10417149 Predominance of CD4 Th1 and CD8 Tc1 cells revealed by characterization of the cellular immune response generated by immunization with a DNA vaccine containing a Trypanosoma cruzi gene.
2191 10417149 As several studies provided strong evidence that during infection CD4 Th1 and CD8 T cytotoxic type 1 (Tc1) cells are important factors in host resistance, the present study was designed to evaluate which T-cell types were activated in DNA-vaccinated BALB/c mice.
2192 10417149 We found that bulk cells from DNA-immunized mice had CD4 and CD8 T cells that produced gamma interferon (IFN-gamma) but not interleukin-4 (IL-4) or IL-10.
2193 10417149 To characterize the TS-specific T cells at the clonal level, we generated CD4 and CD8 clones.
2194 10417149 We obtained cytotoxic CD4 clones of the Th1 type that secreted large amounts of IFN-gamma but not IL-4 or IL-10.
2195 10417149 Unexpectedly, we obtained other CD4 clones with a Th2 phenotype, secreting IL-4 and IL-10 but not IFN-gamma.
2196 10417149 All CD8 clones were cytotoxic and produced IFN-gamma.
2197 10417149 IL-4 and IL-10 were not secreted by these cells.
2198 10417149 The antiparasitic activity of a CD4 Th1 and a CD8 Tc1 clone was assessed in vitro.
2199 10417149 CD4 or CD8 T cells significantly inhibited T. cruzi development in infected macrophages or fibroblasts, respectively.
2200 10417149 We concluded that DNA vaccine efficiently generates potentially protective CD4 Th1 and CD8 Tc1 cells specific for a T. cruzi antigen, therefore reinforcing the possibility of using this strategy for developing a preventive or therapeutic vaccine against Chagas' disease.
2201 10417149 Predominance of CD4 Th1 and CD8 Tc1 cells revealed by characterization of the cellular immune response generated by immunization with a DNA vaccine containing a Trypanosoma cruzi gene.
2202 10417149 As several studies provided strong evidence that during infection CD4 Th1 and CD8 T cytotoxic type 1 (Tc1) cells are important factors in host resistance, the present study was designed to evaluate which T-cell types were activated in DNA-vaccinated BALB/c mice.
2203 10417149 We found that bulk cells from DNA-immunized mice had CD4 and CD8 T cells that produced gamma interferon (IFN-gamma) but not interleukin-4 (IL-4) or IL-10.
2204 10417149 To characterize the TS-specific T cells at the clonal level, we generated CD4 and CD8 clones.
2205 10417149 We obtained cytotoxic CD4 clones of the Th1 type that secreted large amounts of IFN-gamma but not IL-4 or IL-10.
2206 10417149 Unexpectedly, we obtained other CD4 clones with a Th2 phenotype, secreting IL-4 and IL-10 but not IFN-gamma.

2213 10417149 As several studies provided strong evidence that during infection CD4 Th1 and CD8 T cytotoxic type 1 (Tc1) cells are important factors in host resistance, the present study was designed to evaluate which T-cell types were activated in DNA-vaccinated BALB/c mice.
2214 10417149 We found that bulk cells from DNA-immunized mice had CD4 and CD8 T cells that produced gamma interferon (IFN-gamma) but not interleukin-4 (IL-4) or IL-10.

2259 10430099 We have recently demonstrated that a synthetic vaccine representing five copies of the MUC1 tandem repeat peptide can be used to prime MUC1-specific human CD4+ T cells in vitro.
2260 10430099 Immunization induced MUC1-specific IFN-gamma but not interleukin 4 expression in CD4+ T cells from PBMCs and draining lymph nodes.

2267 10438927 CD8+ lymphocytes from IL-4-vaccinated IFN-gamma knockout (KO), but not from IL-4 KO, mice cured lung metastases, thus indicating that IL-4 produced by Tc2 cells was instrumental for tumor rejection.
2268 10447773 Although MSP119 alone could induce a small but detectable T-cell response, which included interleukin-4 (IL-4) secretion, this response was significantly increased by the presence of IL-2.
2269 10447773 In addition, IL-4 was shown to synergize with IL-2 for the induction of antigen-specific T-cell responses.
2270 10447773 If interferon-gamma (IFN-gamma), IL-12, or neutralizing anti-IL-4 antibody was present at the time of priming, the T-cell responses were abolished.
2271 10447773 Parasite-specific immunoglobulin G (IgG) could be detected after secondary restimulation with MSP119, IL-10 and anti-CD40 monoclonal antibody in cultures containing MSP119 primed T cells, autologous B cells, IL-2 and IL-4.

2284 10456874 Supernatants from rHag B-stimulated splenic lymphoid cell cultures from immunized rats contained high levels of gamma interferon, followed by interleukin-2 (IL-2), IL-10, and then IL-4.
2285 10456906 Immunization of mice with recombinant TolT generates a population of CD4(+) T lymphocytes that recognize T. cruzi-infected macrophages, resulting in the production of gamma interferon (IFN-gamma), which leads to NO production and a 50 to 60% reduction in parasite numbers compared to that seen with infected macrophages incubated with naive T cells.
2286 10456906 This population of T cells also produces both IFN-gamma and interleukin 2 (IL-2) but not IL-4 or IL-5 when incubated with spleen cells stimulated with TolT antigen, indicating that they are of the T-helper 1 type.
2287 10457199 Expression of IFN-gamma or TNF was protective.
2288 10457199 Interleukin-4 exacerbation was T cell independent and was reflected in the failure of macrophage activation, possibly due to suppression of NK cells, which are a source of IFN-gamma early in infection.
2289 10462233 Low doses of IL-12 (10 ng) reduced IL-4 and IL-5 secretion (but did not affect IL-10 production) and decreased inflammatory signs whereas high doses of IL-12 had no effects.
2290 10473523 Cytokine reconstitution experiments demonstrated that while addition of recombinant IL-12 (rIL-12) plus anti-IL-4 restored PPD-specific responses in the NN group, it had no effect in the PN group.
2291 10477587 CD40-CD40 ligand costimulation is required for generating antiviral CD4 T cell responses but is dispensable for CD8 T cell responses.
2292 10477587 This study documents a striking dichotomy between CD4 and CD8 T cells in terms of their requirements for CD40-CD40 ligand (CD40L) costimulation.
2293 10477587 CD40L-deficient (-/-) mice made potent virus-specific CD8 T cell responses to dominant as well as subdominant epitopes following infection with lymphocytic choriomeningitis virus.
2294 10477587 There were 10-fold fewer virus-specific CD4 T cells in CD40L-/- mice compared with those in CD40L+/+ mice, and this inhibition was seen for both Th1 (IFN-gamma, IL-2) and Th2 (IL-4) responses.
2295 10482309 Recent studies have indicated that type 1 T cell responses (potent interferon-gamma and cytolytic responses, with absence of interleukin-4 production) are important for protective immunity against mycobacteria.
2296 10501236 Enhanced production of interferon-gamma (IFN-gamma) and complete absence of interleukin-4 (IL-4) in splenocytes of pCMXENV-immunized mice on restimulation with JEV antigens in vitro indicated that the protection is likely to be mediated by T helper (Th) lymphocytes of the Th1 sub-type.
2297 10501247 The fully protective aqueous vaccine group produced higher levels of interferon gamma (IFNgamma) and interleukin 4 (IL-4) than the water-in-oil vaccine group following a live parasite challenge infection.
2298 10501247 Furthermore, mice vaccinated with the aqueous vaccine displayed prolonged IFNgamma and IL-4 response as compared to mice that received the same antigens without adjuvants.
2299 10501247 These data support the hypothesis that both the Th1 cytokine IFNgamma, and the Th2 cytokine IL-4 are modulated by the vaccine vehicle and adjuvant used for vaccination, thus possibly affecting expression of protective immune responses.
2300 10501247 The fully protective aqueous vaccine group produced higher levels of interferon gamma (IFNgamma) and interleukin 4 (IL-4) than the water-in-oil vaccine group following a live parasite challenge infection.

2306 10501612 Whereas cells from mice infected only with T. spiralis produced the cytokine IL-4 and little or no IFNgamma when stimulated in vitro, cells from animals infected with T. spiralis and with trypanosomes released large amounts of IFNgamma but no IL-4.
2307 10505110 DC were derived from the adherent fraction of PBMC by culture in defined medium containing GM-CSF and IL-4.
2308 10505849 Induced immunity by expression of interleukin-2 or GM-CSF gene in murine neuroblastoma cells can generate antitumor response to established tumors.
2309 10505849 For that purpose, we transduced low immunogenic C1300 cells with interleukin-2 (IL-2), GM-CSF, or IL-4 genes.
2310 10505849 A loss of tumorigenicity in syngeneic mice was observed using IL-2- and GM-CSF- but not IL-4-producing C1300 cells, although their in vitro growth rates were not affected by the transduction.
2311 10505849 The syngeneic mice that had rejected IL-2 or GM-CSF producers did not develop tumors of wt cells inoculated subsequently, but formed tumors of irrelevant syngeneic mammary tumor cells.
2312 10505849 Accordingly, the inoculation of IL-2 or GM-CSF producers into immunocompetent mice generated tumor-specific acquired immunity.
2313 10505849 The induced immunity using IL-2 or GM-CSF producers was also effective in eradicating established subcutaneous tumors of wt cells and in reducing the number of preexisting metastatic foci in the liver.
2314 10505849 These data suggest a potential application of IL-2- or GM-CSF-producing syngeneic tumor cells for the treatment of low immunogenic neuroblastomas.
2315 10505849 Induced immunity by expression of interleukin-2 or GM-CSF gene in murine neuroblastoma cells can generate antitumor response to established tumors.

2322 10508191 Antigen-specific lympho-proliferative responses in vitro were reduced by 65% in the pretreated group; IL-5 and IL-4 production were decreased in responder cells of lungs and spleens of nasally pretreated mice.
2323 10508191 In contrast, mucosal administration of rBet v 1-CTB conjugates prior to sensitization led to an up-regulation of allergen-specific IgE, IgG1 and IgG2a, increased in vitro lympho-proliferative responses as well as augmented production of IL-5, IL-4, IL-10 and IFN-gamma.
2324 10508191 Antigen-specific lympho-proliferative responses in vitro were reduced by 65% in the pretreated group; IL-5 and IL-4 production were decreased in responder cells of lungs and spleens of nasally pretreated mice.

2326 10508258 In contrast, most in vitro as well as in vivo human studies involve the use of DC generated from adherent peripheral blood-derived monocytes in the presence of GM-CSF and IL-4.
2327 10510388 Tumor regression after adoptive transfer of effector T cells is independent of perforin or Fas ligand (APO-1L/CD95L).
2328 10510388 Perforin- and Fas ligand (APO-1/CD95 ligand)-mediated cytotoxicity have been proposed as mechanisms for T cell-mediated tumor destruction.
2329 10510388 To determine the role of perforin and Fas ligand (FasL) in T cell-mediated tumor regression in a murine melanoma model, B16BL6-D5 (D5), we generated D5-specific effector T cells from tumor vaccine-draining lymph nodes of wild type (wt), perforin knock out (PKO), or FasL mutant (gld) mice and treated established D5 metastases in mice with the same genotype.
2330 10510388 Therapeutic T cells from wt, PKO, or gld mice exhibit a tumor-specific type 1 cytokine profile; they secrete IFN-gamma, but not IL-4.
2331 10510390 No increase in IL-4 or IL-10 was found in cell culture supernatants from either control or experimental groups.
2332 10515123 Initial rise of all splenic cytokines and serum anti-SEA IgE levels at 6 weeks p.i. was observed, followed by a dramatic drop in the levels of the proinflammatory cytokines IL-2, IFNgamma, IL-4 and TNF-alpha and IgE at 8 weeks of infection.
2333 10515829 Several epitopes in the circumsporozoite protein (CSP) were identified as targets of cultured interferon (IFN)-gamma-secreting CD4+ T cells.
2334 10515829 RTS,S-specific IFN-gamma-secreting effector T cells were induced in 8 subjects; this ex vivo response mapped to a single peptide in Th2R.
2335 10515829 CSP-specific CD8+ cytotoxic T lymphocytes were not detected.
2336 10515829 RTS, S-specific IFN-gamma production was universal, whereas interleukin-4 and -5 production was rare.
2337 10525444 Iscoms prominently enhance the antigen targeting, uptake, and activity of antigen presenting cells including dendritic and B cells and macrophages resulting in the production of proinflammatory cytokines, above all interleukin (IL)-1, IL-6, and IL-12.
2338 10525444 The expression of costimulatory molecules major histocompatibility complex (MHC) class II, B7.1 and B7.2, is also enhanced.
2339 10525444 Iscoms enhance the Th1 type of response with increased production of IL-2 and interferon gamma.
2340 10525444 IL-4, IL-2, and interferon gamma (IFNgamma) together with the beta chemokines MIP-1alpha and MIP-1beta correlated with protection against challenge infection with a chimeric virus (simian immunodeficiency virus-human immunodeficiency virus).
2341 10528174 We also studied the possible impact of coinjection of plasmid DNA encoding rat cytokines IL-4, IL-10, GM-CSF, and TNF-alpha with the ISS-containing DNA vaccine.
2342 10528174 Coinjection of IL-4-, IL-10-, or TNF-alpha-coding cDNA inhibited the suppressive effect of the DNA vaccine on EAE, whereas GM-CSF-coding cDNA had no effect.

2345 10537336 Selective in vivo mobilization with granulocyte macrophage colony-stimulating factor (GM-CSF)/granulocyte-CSF as compared to G-CSF alone of dendritic cell progenitors from peripheral blood progenitor cells in patients with advanced breast cancer undergoing autologous transplantation.
2346 10537336 DCs develop from myeloid progenitor populations under the influence of granulocyte macrophage colony-stimulating factor (GM-CSF) and pass through an intermediate stage of maturation that is characterized by CD14 expression.
2347 10537336 PBPCs mobilized in 10 patients with GM-CSF for 1 week, followed by the combination of GM-CSF and G-CSF, were compared with those obtained from patients receiving G-CSF alone with respect to the presence of DC progenitors and the capacity to generate functionally active mature DCs.
2348 10537336 PBPCs mobilized with GM-CSF/G-CSF were markedly enriched for CD14+ DC progenitor cells as compared with those mobilized with G-CSF alone.
2349 10537336 Consistent with an immature progenitor population, the CD14+ cells express Ki-67 antigen but not nonspecific esterase.

2390 10570193 To better understand the role that CD4(+) T helper responses may play in mediating protection in this model, we characterized SIV-specific proliferative and cytokine responses in macaques immunized with live attenuated SIV strains.
2391 10570193 SIV-specific stimulation of lymphocytes from vaccinated macaques resulted in secretion of interferon-gamma, IL-2, regulated-upon-activation, normal T cells expressed and secreted (RANTES), macrophage inflammatory protein (MIP)-1alpha, and MIP-1beta but not IL-4 or IL-10.

2393 10579123 Type 1 T helper (Th1) cells produce interferon-gamma, interleukin (IL)-2, and tumour necrosis factor (TNF)-beta, which activate macrophages and are responsible for cell-mediated immunity and phagocyte-dependent protective responses.
2394 10579123 By contrast, type 2 Th (Th2) cells produce IL-4, IL-5, IL-10, and IL-13, which are responsible for strong antibody production, eosinophil activation, and inhibition of several macrophage functions, thus providing phagocyte-independent protective responses.
2395 10586074 As a measure for the induction of a Th1 and/or Th2 response, we determined specific IgG subclasses and examined IFN-gamma, Il-4, and Il-5 induction.

2435 10614503 With respect to IgA antibody production in the gut whereas IL-4 and TGF-beta have been implicated in isotype switching of precursor cells to IgA commitment, their subsequent localisation, proliferation and effector activity expression is dependent on IL-5 and IL-6 expression locally.
2436 10614503 Whereas IgA+ cells of the B2 lineage are IL-6 dependent but IL-5 independent, B1-derived IgA+ cells are IL-5 dependent and IL-6 independent.

2440 10614729 As shown by adoptive cell transfer, both CD4+ and CD8+ T cells from pDNA immunized mice inhibited an IgE response to beta-gal in alum in the recipient mice. pDNA immunization also inhibited the eosinophilic infiltration of the lung of ovalbumin (OVA) immunized mice after OVA inhalation challenge in an animal model of the late phase reaction.

2451 10623812 Vaccination with mouse mammary adenocarcinoma cells coexpressing B7-1 (CD80) and B7-2 (CD86) discloses the dominant effect of B7-1 in the induction of antitumor immunity.
2452 10623812 Nonreplicating TS/A mammary adenocarcinoma cells expressing B7-2 (CD86) (TS/A-2) are more immunogenic than those expressing B7-1 (CD80) (TS/A-1), indicating that B7-1 and B7-2 display nonredundant costimulatory effects in inducing antitumor responses.
2453 10623812 The expression of B7-1 also modifies quantitatively the balance of endogenous IFN-gamma and IL-4 induced in vivo by TS/A-2 vaccines.
2454 10623812 In fact, we find that vaccination with TS/A-2/1 cells results in the production of more IFN-gamma and less IL-4 than TS/A-2 vaccines, a pattern comparable to that induced by TS/A-1 cells.

2459 10623847 However, a role for IL-10, B7.1, and CD40 expression in Th2 response inhibition was suggested.
2460 10623847 The role of IL-10 was demonstrated in mice exhibiting combined deficiencies in IL-12 and IL-10.
2461 10623847 Here, a marked increase in egg-specific IL-4/IL-5-producing cells confirmed a role for both cytokines in Th2 response inhibition.
2462 10623847 However, in marked contrast to IL-12-deficient animals, a significant increase in IFN-gamma-producing cells likely explains the reduced Th2 response in IL-10/IL-12-deficient mice.
2463 10623847 Thus, a novel IL-12-independent type 1-inducing pathway was revealed in the combined absence of IL-12 and IL-10.
2464 10623847 Together, these data demonstrate 1) that the Th1-promoting activity of CpG DNA is controlled by IL-12 and IL-10, and 2) that Th2 response inhibition by CpG ODN involves IL-12-independent changes in IL-10 and costimulatory molecule expression.

2471 10652120 The results of the present study show that Th1 cytokines predominated in the early inflammatory response and might be involved in control of levels of acute parasitaemia whereas the Th2-associated responses, including expression of IL-4 and IL-10 and the production of parasite-specific IgG, might be the functional means for the reduction and clearance of the parasite from the body.

2477 10657678 Following inoculation, PBMC from 95 and 87% of volunteers exhibited an increased production of IFN-gamma and IL-10, respectively, in response to Shigella Ags.
2478 10657678 No IL-4 or IL-5 responses were detected.
2479 10678904 The cytokine response to Shigella-specific antigens observed in volunteers' PBMC following vaccination suggested a Th1 pattern with stimulation of gamma interferon and absence of interleukin 4 (IL-4) or IL-5.
2480 10678951 Conversely, during infection local production of IL-6 and IL-1ra was significantly greater in mice immunized with Pa than in those immunized with Pw.
2481 10678951 Furthermore, the levels of IL-1beta, IL-6, and IL-1ra in Pa-immunized IL-4(-/-) mice were comparable to those in mice immunized with Pw.
2482 10678966 Susceptibility of BALB/c mice to Leishmania major infection has been correlated to the preferential development of Th2 CD4 T cells through an early production of interleukin 4 (IL-4) by a restricted population of CD4 T cells which react to a single parasite antigen, LACK (stands for Leishmania homologue of receptors for activated C kinase).
2483 10678966 Experimental vaccination with LACK can redirect the differentiation of CD4(+) T cells towards the Th1 pathway if LACK is coadministrated with IL-12.
2484 10678966 After a single injection of LACK-expressing L. monocytogenes, IL-12/p40 transcripts showed a rapid burst, and peaks of gamma interferon (IFN-gamma)-secreting LACK-specific Th1 cells were detected around day 5 in the spleens and livers of mice of both strains.
2485 10678966 Thus, our results demonstrate that, in addition of its recognized use for the induction of effector CD8 T cells, L. monocytogenes can also be used as a live recombinant vector to favor the development of potentially protective IFN-gamma-secreting Th1 CD4 T lymphocytes.
2486 10687150 These transiently transduced dendritic cells, derived from melanoma patients' monocytes cultured with granulocyte-macrophage colony-stimulating factor and interleukin-4, express the transgene and can stimulate patients' CD8+ T cells to elicit an antitumor immune response comparable to dendritic cells loaded with a defined peptide.
2487 10689136 The generation of DC from blood monocytes in response to GM-CSF and IL-4 treatment was similar in cells from young and old persons.
2488 10689136 The DC population thus obtained had a typical dendritic morphology and expressed DC surface markers, such as HLA class II, CD1a, CD11c, CD54, CD80 and CD86, but not CD14 for a period of up to three weeks in culture.
2489 10689136 DC from young and old persons produced IL-12 and TNF-alpha and responded equally well to maturation-inducing stimuli.
2490 10689152 No significant IL-4 secretion was observed in any subject, whereas the presence of IFN-gamma secretion was found to correlate with good responder status.

2497 10699330 These results indicate that the BCG-Leishmania vaccine stimulates the production of IL-12 and IFN-gamma, but inhibits that of IL-10 and is without effect on IL-4 when mice are infected with T. cruzi.
2498 10699330 This highlights the key role of endogenously produced IFN-gamma, IL-10 and IL-12 in the control of T. cruzi acute and chronic infection in mice and the favorable modulation of their balance by a vaccination combining BCG and Leishmania.

2507 10706700 The importance of these S-100+ cells or both CD8+ and CD11c+ cells, especially that of dendritic cells (DCs), was also studied.

2513 10713654 Although culture conditions are extremely diverse, the majority of protocols grow DCs in GM-CSF and either TNF-alpha and/or IL-4.
2514 10713654 The addition of other growth factors such as SCF and Flt-3 ligand can dramatically enhance DC recovery.
2515 10715522 The immune responses induced by each formulation were characterised by antigen specific total and subclass serum responses, and by lymphocyte proliferation and cytokine (interleukin-2 (IL-2), interleukin-4 (IL-4) and interferon-gamma (IFN-gamma)) production by in vitro restimulated spleen cells.
2516 10715522 Higher IgG2a and neutralising antibody levels, IL-2 and IFN-gamma levels and lymphoproliferative responses were noted in mice immunised with the HSV-2 ISCOM formulated vaccine preparation.
2517 10715522 Furthermore, although HSV-2 antigens formulated in dehydration-rehydration NISV, or entrapped in NISV by freeze-thawing at 30 degrees C (HSV-2 NISV 30), also elicited relatively high antibody, IL-2 and IFN-gamma levels and relatively high lymphoproliferative responses, formulation of HSV-2 antigens by freeze-thawing with NISV at 60 degrees C (HSV-2 NISV 60) did not.
2518 10722593 Despite this strong protective response, LPS purified from F. tularensis LVS did not activate murine B cells for proliferation or polyclonal immunoglobulin secretion, nor did it activate murine splenocytes for secretion of interleukin-4 (IL-4), IL-6, IL-12, or gamma interferon (IFN-gamma).

2529 10725728 In addition, these animals showed dramatic increases in IFN-gamma-, IL-2-, and IL-4-secreting cells, and in IgG2a Ab levels upon adult challenge compared with mice primed with vaccine alone.

2535 10741391 However, CD4+ T lymphocytes from mice immunized with the constitutive promoter secreted IL-4, IL-5, IL-6, IL-10 and IFN-gamma (Th1/Th2 pattern), whereas CD4+ cells mainly secreted IFN-gamma (Th1 pattern) when the second construct was used.
2536 10741704 The detection of tumor-specific T cells in immunized cancer patients usually relies on lengthy and difficult CTL assays; we now report on flow cytometry to detect the intracellular cytokines interleukin 2 (IL-2), IL-4, IFN-gamma, and tumor necrosis factor alpha (TNF-alpha) produced by CD4+CD69+ and CD8+CD69+ activated T cells after MUC1 antigen stimulation.
2537 10741704 After stimulation in vitro with MUC1-variable number of tandem repeats peptides, CD8+CD69+ T cells from all immunized patients generated 3-9 times higher levels of TNF-alpha(P < 0.038) and IFN-gamma (P <0.010) than did cells from 12 normal subjects; minor increases in IL-4 occurred.
2538 10741704 By contrast, CD4+CD69+ cells showed no overall alteration in TNF-alpha and IFN-gamma cytokine production, although in some patients, their measurement was informative; the measurement of IL-2 was not useful in either CD4+CD69+ or CD8+CD69+ cells.

2582 10770625 Enhanced antitumoral effect of adenovirus-mediated cytosine deaminase gene therapy by induction of antigen-presenting cells through stem cell factor/granulocyte-macrophage colony-stimulating factor gene transfer.
2583 10770625 We preinjected the mice with murine stem cell factor (SCF)-encoding adenovirus (AdSCF) and murine granulocyte-macrophage colony-stimulating factor (GM-CSF)-encoding adenovirus (AdGM-CSF); after 7 days, the mice were inoculated with CT26 colon adenocarcinoma.
2584 10770625 Cytotoxic T-lymphocyte activity was induced efficiently after the combined therapy, and mRNA of tumor necrosis factor-alpha, interleukin-4, interferon-gamma, and interleukin-2 was present in the tumor mass after combined therapy, suggesting that a more potent antitumoral response was induced by enhanced APCs.
2585 10775783 Immune responses were defined by: (i) SU antibody titers; (ii) the ratio of SU IgG1 and IgG2 antibodies; (iii) interferon gamma (IFNgamma) and IL-4 gene expression and proliferative response of SU stimulated lymph node mononuclear cells (LNMC).

2589 10775795 Immunohistochemical analysis of cytokine-producing cells in the gut villi showed no significant induction of the cytokines IL-1alpha, IFN-gamma, IL-4 or IL-10 after oral administration of wild type Lactobacillus strains.
2590 10775795 In contrast, oral administration of L. reuteri and L. brevis induced expression of the proinflammatory/Th1 cytokines TNF-alpha, IL-2 and/or IL-1beta.
2591 10792505 Rhesus macaques were immunized by a modified targeted lymph nodes (TLN) route with recombinant simian immunodeficiency virus (SIV) glycoprotein 120 (gp120) and p27 in alum, and adsorbed recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) with either interleukin (IL)-2 or IL-4.
2592 10792505 Immunization induced significant increases in the concentrations of CD8 cell-derived suppressor factor (CD8-SF), regulated on activation normal T cells expressed and secreted (RANTES), macrophage inflammatory protein (MIP)-1alpha and MIP-1beta, and down-modulation of the proportion of cells expressing CCR5 (r = 0.737, P<0.05).

2596 10811123 In additional adoptive transfer experiments, an essential role for CD4+ T cells in immunity was observed because their depletion from among splenocytes of 9LmIL4-immunized rats eliminated the protective effective against 9L, whereas depletion of CD8+ cells resulted in a more limited effect on protection against 9L.

2598 10811870 Type I IFNs induced a surprisingly rapid maturation of monocytes into short-lived tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-expressing DCs endowed with potent functional activities, superior with respect to the interleukin (IL)-4/GM-CSF treatment, as shown by FACS((R)) analyses, mixed leukocyte reaction assays with allogeneic PBLs, and lymphocyte proliferation responses to HIV-1-pulsed autologous DCs.

2604 10816449 The UbA64 DNA vaccine induced a weak humoral response compared to UbG64, and a mixed population of interleukin-4 (IL-4)- and gamma interferon (IFN-gamma)-secreting cells.
2605 10816449 Vaccination with the UbGR64 plasmid generated a strong Th1 cell response (high IFN-gamma, low IL-4) in the absence of a detectable humoral response.
2606 10816449 The expression of mycobacterial antigens from DNA vaccines as fusion proteins with a destabilizing ubiquitin molecule (UbA or UbGR) shifted the host response toward a stronger Th1-type immunity which was characterized by low specific antibody levels, high numbers of IFN-gamma-secreting cells, and significant resistance to a tuberculous challenge.

2610 10816476 Mice vaccinated with either of the beta-galactosidase-expressing recombinant RB51 strains developed specific antibodies of predominantly the immunoglobulin G2a (IgG2a) isotype, and in vitro stimulation of their splenocytes with beta-galactosidase induced the secretion of gamma interferon (IFN-gamma), but not interleukin-4 (IL-4).
2611 10816476 A Th1 type of immune response to HSP65, as indicated by the presence of specific serum IgG2a, but not IgG1, antibodies, and IFN-gamma, but not IL-4, secretion by the specific-antigen-stimulated splenocytes, was also detected in mice vaccinated with strain RB51 containing pBBgroE/hsp65.
2612 10816476 Mice vaccinated with either of the beta-galactosidase-expressing recombinant RB51 strains developed specific antibodies of predominantly the immunoglobulin G2a (IgG2a) isotype, and in vitro stimulation of their splenocytes with beta-galactosidase induced the secretion of gamma interferon (IFN-gamma), but not interleukin-4 (IL-4).

2614 10820246 These bovine insulin-primed CTL displayed a type 0 CTL phenotype, producing IL-4, IL-5, IL-10, low levels of IFN-gamma, but no TNF-alpha.
2615 10820246 By contrast, CTL generated from C57BL/6 mice primed with OVA in CFA produced IFN-gamma and TNF-alpha but no IL-4, IL-5, or IL-10 and therefore were classified as type 1 CTL.
2616 10820246 Although both types of CTL express many of the same cell-surface Ags, OVA-specific CTL but not bovine insulin-primed CTL expressed CT-1, a carbohydrate epitope of CD45, and bovine insulin-primed CTL but not OVA-specific CTL expressed Fas constitutively.
2617 10820246 Neither endogenous IL-4 nor the dose of priming Ag altered the CTL phenotypes, but the antigenic peptides of OVA and bovine insulin were key to determining the differentiation of either type 1 or type 0 CTL.
2618 10820246 These bovine insulin-primed CTL displayed a type 0 CTL phenotype, producing IL-4, IL-5, IL-10, low levels of IFN-gamma, but no TNF-alpha.

2626 10825606 Proliferating PBMC secreted peak levels of interleukin-2 (IL-2) at 2 days and peak levels of tumor necrosis factor-beta (TNF-beta), interferon-gamma (IFN-gamma), IL-4 and IL-10 at 3-6 days post-stimulation.
2627 10825606 In contrast, nonproliferating PBMC (whether from nonresponders, naive subjects or weak responders) did not produce detectable levels of TNF-beta or IFN-gamma, nor was IL-4 or IL-10 produced significantly, and that produced had a different kinetic profile from that of proliferating PBMC.
2628 10825606 Proliferating PBMC secreted peak levels of interleukin-2 (IL-2) at 2 days and peak levels of tumor necrosis factor-beta (TNF-beta), interferon-gamma (IFN-gamma), IL-4 and IL-10 at 3-6 days post-stimulation.
2629 10825606 In contrast, nonproliferating PBMC (whether from nonresponders, naive subjects or weak responders) did not produce detectable levels of TNF-beta or IFN-gamma, nor was IL-4 or IL-10 produced significantly, and that produced had a different kinetic profile from that of proliferating PBMC.
2630 10841077 For example, coadministration of costimulatory molecules (CD80 and CD86), proinflammatory cytokines (interleukin-1alpha [IL-1alpha], tumor necrosis factor-alpha [TNF-alpha, and TNF-beta), Th1 cytokines (interleukin-2 [IL-2], IL-12, IL-15, and IL-18), Th2 cytokines (IL-4, IL-5, and IL-10), and granulocytes-macrophage colony-stimulating factor (GM-CSF) with DNA vaccine constructs leads to modulation of the magnitude and direction (humoral or cellular) of the immune responses.
2631 10841077 To further engineer the immune response in vivo, we compared the induction and regulation of immune responses from the codelivery of chemokine (IL-8, interferon-gamma-inducible protein-10 [gammaIP-10], macrophage inhibitory protein-1alpha [MIP-1alpha], and RANTES) genes with codelivery of cytokine genes.
2632 10841077 We observed that coimmunization with IL-8, gammaIP-10, and MIP-1alpha genes increased the antibody response.
2633 10841077 We also found that coinjection with IL-8, gammaIP-10, and RANTES resulted in a dramatic enhancement of T helper (Th) proliferation response.
2634 10841077 This enhancement of CTL responses observed from the coinjection with RANTES was CD8+ T cell dependent.
2635 10843701 Thus, LPS-matured dendritic cells (DC1) promote a Th1 response (increased generation of IFN-gamma and reduced production of IL-4) by Ag-stimulated CD4+ T cells from the DO.11.10 transgenic mouse expressing a TCR specific for an OVA peptide (OVA323-339).
2636 10843701 In contrast, a phosphorylcholine-containing glycoprotein, ES-62, secreted by the filarial nematode, Acanthocheilonema viteae, which generates a Th2 Ab response in vivo, is found to induce the maturation of dendritic cells (DC2) with the capacity to induce Th2 responses (increased IL-4 and decreased IFN-gamma).
2637 10843701 In addition, we show that the switch to either Th1 or Th2 responses is not effected by differential regulation through CD80 or CD86 and that a Th2 response is achieved in the presence of IL-12.
2638 10843701 Thus, LPS-matured dendritic cells (DC1) promote a Th1 response (increased generation of IFN-gamma and reduced production of IL-4) by Ag-stimulated CD4+ T cells from the DO.11.10 transgenic mouse expressing a TCR specific for an OVA peptide (OVA323-339).
2639 10843701 In contrast, a phosphorylcholine-containing glycoprotein, ES-62, secreted by the filarial nematode, Acanthocheilonema viteae, which generates a Th2 Ab response in vivo, is found to induce the maturation of dendritic cells (DC2) with the capacity to induce Th2 responses (increased IL-4 and decreased IFN-gamma).
2640 10843701 In addition, we show that the switch to either Th1 or Th2 responses is not effected by differential regulation through CD80 or CD86 and that a Th2 response is achieved in the presence of IL-12.
2641 10845721 Chimeric forms of IL-4 with the type I transmembrane protein CD4 or type II transmembrane protein TNF were designed to express IL-4 in opposite orientations on the tumor cell surface.
2642 10845721 Expression of the IL-4/TNF chimeric protein on MethA cells elicited antitumor immunity and protected from MethA tumor challenge.
2643 10845721 Chimeric forms of IL-4 with the type I transmembrane protein CD4 or type II transmembrane protein TNF were designed to express IL-4 in opposite orientations on the tumor cell surface.
2644 10845721 Expression of the IL-4/TNF chimeric protein on MethA cells elicited antitumor immunity and protected from MethA tumor challenge.
2645 10856789 However, they differed in the isotype profile albeit only transiently, with the IL-4-transduced DC group showing higher IgE and lower IgG2a responses, and in the cytokine profile, with spleen cells isolated from the IL-4-transduced DC group producing higher IL-13 and lower IL-12.
2646 10856799 Cytokine profiles in immunized C57BL/6 mice demonstrated Th1 bias, with IFN-gamma and IL-2 production and lack of IL-4 and IL-5.
2647 10858197 Antigen-specific production of interleukin-4 (IL-4), IL-5, IL-6, IL-9, IL-10, IL-13, and gamma interferon (IFN-gamma) was determined at each sample point, in parallel with polyclonal (phytohemagglutinin PHA-induced) cytokine responses.
2648 10858219 Beryllium is associated with a human pulmonary granulomatosis characterized by an accumulation of CD4(+) T cells in the lungs and a heightened specific lymphocyte proliferative response to beryllium (Be) with gamma interferon (IFN-gamma) release (i.e., a T helper 1 [Th1] response).
2649 10858219 If interleukin-12 (IL-12) is given during in vivo sensitization with SLA, markedly increased IFN-gamma production and decreased IL-4 production are detected.
2650 10858219 We show here that when beryllium sulfate (BeSO(4)) was added during in vivo sensitization of BALB/c mice with SLA and IL-12, significantly increased IFN-gamma production and decreased IL-4 production from lymph node and spleen cells were detected upon in vitro SLA restimulation.
2651 10858219 In vivo, when Be was added to SLA and IL-12 for sensitization of BALB/c mice, more effective control of Leishmania infection was achieved.
2652 10858219 Beryllium is associated with a human pulmonary granulomatosis characterized by an accumulation of CD4(+) T cells in the lungs and a heightened specific lymphocyte proliferative response to beryllium (Be) with gamma interferon (IFN-gamma) release (i.e., a T helper 1 [Th1] response).
2653 10858219 If interleukin-12 (IL-12) is given during in vivo sensitization with SLA, markedly increased IFN-gamma production and decreased IL-4 production are detected.
2654 10858219 We show here that when beryllium sulfate (BeSO(4)) was added during in vivo sensitization of BALB/c mice with SLA and IL-12, significantly increased IFN-gamma production and decreased IL-4 production from lymph node and spleen cells were detected upon in vitro SLA restimulation.
2655 10858219 In vivo, when Be was added to SLA and IL-12 for sensitization of BALB/c mice, more effective control of Leishmania infection was achieved.
2656 10861075 Similar to what occurred upon nasal exposure to viable A. fumigatus conidia, treatment of immunocompetent mice with Aspergillus crude culture filtrate Ags resulted in the development of local and peripheral protective Th1 memory responses, mediated by Ag-specific CD4+ T cells producing IFN-gamma and IL-2 capable of conferring protection upon adoptive transfer to naive recipients.
2657 10861075 Protective Th1 responses could not be observed in mice deficient of IFN-gamma or IL-12 and did not occur in response to Asp f 2, which, on the contrary, elicited high level production of inhibitory IL-4.
2658 10869296 Interestingly, splenic lymphocytes derived from pS/pD-inoculated mice demonstrated significant proliferation responses to recombinant HBsAg and HDAg, and resulted in a Th1-like immune response as suggested by the production of interferon gamma (INF-gamma) and interleukin-2 (IL-2), but not IL-4.
2659 10869769 Co-injection of an expression cassette for the granulocyte-macrophage colony-stimulating factor (GM-CSF) increased both the humoral and cell-mediated immune response with both gD and DeltagD.
2660 10869769 A strong activation of IL-4-secreting cells was observed in the spleen and DLN together with an increase in the number of IFN-gamma-secreting cells.
2661 10874214 The T cells of seven HLA-A31( +) patients with gastric cancers were stimulated in vitro by F4.2-pulsed autologous dendritic cells which had been induced from peripheral blood of each patient by incubation in the presence of granulocyte macrophage colony-stimulating factor (GM-CSF) and IL-4.
2662 10886404 A strong delayed-type hypersensitivity (DTH) reaction was induced in mice co-injected via the intradermal (i.d.) route with a eukaryotic expression plasmid encoding the CD80 molecule (pCD80) and a plasmid encoding the glycoprotein D of the HSV-2 (pgD).
2663 10886404 Furthermore, when spleen cells from these mice were cultured in the presence of inactivated HSV, a significant increase in the expression of interleukin-2 receptor (IL-2R) was observed in the CD4 subset compared with mice immunized only with pgD.
2664 10886404 Analysis of cytokine synthesis at the single-cell level indicated that CD80 genes induce a significant increase in the number of interferon-gamma (IFN-gamma)-, IL-2- and IL-4-secreting cells in the spleen.
2665 10886404 When a plasmid carrying the CD86 gene (pCD86) was co-injected via the i.m. route with the pgD plasmid, a small decrease in the number of IFN-gamma-secreting cells was observed.
2666 10886404 This down-regulation of the immune response was also observed when eukaryotic expression cassettes for CD80 and for CD86 were co-administered with the pgD plasmid via the i.d. route.
2667 10886779 None of the antigen preparations stimulated interleukin (IL)-4 production but, in contrast to the other antigens, whole E. coli, as well as purified O6 LPS, induced large quantities of IL-10.
2668 10886779 Blocking of IL-10 by neutralizing antibodies increased both E. coli-induced proliferation and IFN-gamma production markedly.
2669 10886779 Conversely, the addition of whole E. coli or LPS to cultures stimulated with other antigens (C. albicans or Staphylococcus aureus) down-regulated proliferative and IFN-gamma responses, an effect which was at least partly IL-10 dependent.
2670 10886779 The results indicate a substantial T-cell memory to commensal E. coli, but suggest that the evidence of such memory, e.g. proliferation and IFN-gamma production, is effectively prevented by IL-10 and perhaps other factors produced by monocytes in response to bacteria.
2671 10915558 LFA-3 plasmid DNA enhances Ag-specific humoral- and cellular-mediated protective immunity against herpes simplex virus-2 in vivo: involvement of CD4+ T cells in protection.
2672 10915558 Adhesion molecules lymphocyte function-associated antigen (LFA)-1 and CD2 on T cells recognize intercellular adhesion molecule (ICAM)-1 and LFA-3 on APCs, respectively.
2673 10915558 To investigate specific roles of adhesion molecules in immune induction we coimmunized LFA-3 and ICAM-1 cDNAs with a gD plasmid vaccine and then analyzed immune modulatory effects and protection against lethal herpes simplex virus (HSV)-2 challenge.
2674 10915558 LFA-3 also enhanced Th cell proliferative responses and production of interleukin (IL)-2, interferon-gamma, IL-4, and IL-10 from splenocytes.
2675 10915558 In contrast, ICAM-1 showed slightly increasing effects on T-cell proliferation responses and cytokine production. beta-Chemokine production (RANTES, MIP-1alpha, and MCP-1) was also influenced by LFA-3 or ICAM-1.
2676 10915558 When animals were challenged with a lethal dose of HSV-2, LFA-3-coimmunized animals exhibited an enhanced survival rate, as compared to animals given ICAM-1 or gD DNA vaccine alone.
2677 10915558 These studies demonstrate that adhesion molecule LFA-3 can play an important role in generating protective antigen-specific immunity in the HSV model system through increased induction of CD4+ Th1 T-cell subset.
2678 10916759 Phase 1 study in patients with metastatic melanoma of immunization with dendritic cells presenting epitopes derived from the melanoma-associated antigens MART-1 and gp100.
2679 10916759 Furthermore, DC-like function can be elicited from peripheral blood monocytes cultured in vitro with interleukin-4 and granulocyte-macrophage colony-stimulating factor.
2680 10916759 The DCs were generated by 5- to 7-day incubation in interleukin-4 (1,000 U/mL) and granulocyte-macrophage colony-stimulating factor (1,000 U/mL) of peripheral blood monocytes obtained by leukapheresis.
2681 10916759 Before administration, the DCs were pulsed separately with the HLA-A*0201-associated melanoma epitopes MART-1(27-35) and gp-100-209-2M.
2682 10916759 Phase 1 study in patients with metastatic melanoma of immunization with dendritic cells presenting epitopes derived from the melanoma-associated antigens MART-1 and gp100.
2683 10916759 Furthermore, DC-like function can be elicited from peripheral blood monocytes cultured in vitro with interleukin-4 and granulocyte-macrophage colony-stimulating factor.
2684 10916759 The DCs were generated by 5- to 7-day incubation in interleukin-4 (1,000 U/mL) and granulocyte-macrophage colony-stimulating factor (1,000 U/mL) of peripheral blood monocytes obtained by leukapheresis.

2686 10925361 Transfer of IFNgamma-depleted CD4(+) T cells together with CD8(+) T cells leads to rejection of murine kidney sarcoma in mice.
2687 10925361 Immunity is dependent both on CD8(+) cytotoxic T cells and on CD4(+) T-helper cells.
2688 10925361 By intracytoplasmic staining of CD4(+) cells, IFNgamma-producing (Th1), IL-4-producing (Th2), and IL-10-expressing cells could be identified in vaccinated and non-vaccinated animals responding to tumor growth.
2689 10925361 In contrast, in non-vaccinated mice succumbing to the tumor, the immunosuppressive IL-10-producing cells became more abundant and the frequency of IFNgamma-expressing cells dropped at later time points.
2690 10929063 In BALB/c mice infected via the trachea with Mycobacterium tuberculosis H37Rv there is an initial phase of partial resistance dominated by type 1 cytokines plus tumour necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1), followed by a phase of progressive disease.
2691 10929063 This progressive phase is accompanied by increasing expression of IL-4, and diminished expression of IL-1 and TNF-alpha.
2692 10931131 Peripheral blood mononuclear cells (PBMC) from the majority of children secreted interferon-gamma (IFN-gamma) and a smaller proportion IL-5, in response to specific antigen stimulation in vitro.
2693 10931131 However, following booster immunization, significantly higher concentrations of IL-5, but not IFN-gamma, were produced by PBMC in response to B. pertussis antigens.
2694 10931131 Furthermore, plasma IL-4 and IL-5 concentrations were increased, whereas IFN-gamma concentrations were reduced following booster immunization.
2695 10931142 Lymph node clones from either strain could be categorized as either Th1 or Th0 on the basis of interferon-gamma (IFN-gamma)/IL-4 production.
2696 10931142 Both B6 lung T cell clones were Th1-like and produced IFN-gamma but not IL-4 and IL-10, whereas four BALB/c lung T cell clones were Th2-like and produced IL-4 and IL-10 but not IFN-gamma.
2697 10931142 Lymph node clones from either strain could be categorized as either Th1 or Th0 on the basis of interferon-gamma (IFN-gamma)/IL-4 production.
2698 10931142 Both B6 lung T cell clones were Th1-like and produced IFN-gamma but not IL-4 and IL-10, whereas four BALB/c lung T cell clones were Th2-like and produced IL-4 and IL-10 but not IFN-gamma.
2699 10931381 Here, we describe a culture system for the generation of murine dendritic cells from adherent peripheral blood mononuclear cells by culturing in the presence of granulocyte-macrophage colony stimulating factor and interleukin-4.
2700 10931388 After a short decrease, probably owing to seasonal variation, the birch-pollen-specific proliferation and the interleukin (IL)-4, IL-5, and IL-10 production significantly increased when reaching the maintenance dose and during the subsequent pollen season.
2701 10948100 Spleen cells from rBCG-S1PT-vaccinated mice showed elevated gamma interferon (IFN-gamma) and low interleukin-4 (IL-4) production, as well as increased proliferation, upon pertussis toxin (PT) stimulation, characterizing a strong antigen-specific Th1-dominant cellular response.
2702 10948138 GXM-APC (or APC) immunization caused small increases in the expression of type-2 cytokines (IL-4 and IL-5), but the increases were not always statistically significant.
2703 10948138 The CFA-induced PEC had an activated phenotype characterized by increased numbers of F4/80(+) cells that expressed CD40, B7-1, and B7-2 on their membranes.
2704 10953979 Upon culture with granulocyte-macrophage colony-stimulating factor (GM-CSF) plus interleukin-4 (IL-4) plus tumor necrosis factor alpha (TNFalpha), CMML cells develop DC morphology and acquire the phenotypic characteristics of DCs.
2705 11012616 It has been detected in rheumatoid arthritis (RA) synovial membrane and found to stimulate the production of the proinflammatory cytokines IL-6, IL-8, tumour necrosis factor-alpha (TNF-alpha) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in vitro.
2706 11012616 We therefore investigated the in vitro IL-17 response to a variety of mitogens and antigens, and compared the IL-17 response to interferon-gamma (IFN-gamma), IL-4, IL-10 and TNF-alpha.
2707 11012616 The antigens TT and PPD significantly increased IL-17 mRNA expression over time, but failed to have such an effect at the protein level.
2708 11012616 IL-17 production did not correlate with either the type-1 cytokine IFN-gamma or TNF-alpha or the type-2 cytokine IL-4 or IL-10 at either the mRNA or protein level.
2709 11012616 It has been detected in rheumatoid arthritis (RA) synovial membrane and found to stimulate the production of the proinflammatory cytokines IL-6, IL-8, tumour necrosis factor-alpha (TNF-alpha) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in vitro.
2710 11012616 We therefore investigated the in vitro IL-17 response to a variety of mitogens and antigens, and compared the IL-17 response to interferon-gamma (IFN-gamma), IL-4, IL-10 and TNF-alpha.
2711 11012616 The antigens TT and PPD significantly increased IL-17 mRNA expression over time, but failed to have such an effect at the protein level.
2712 11012616 IL-17 production did not correlate with either the type-1 cytokine IFN-gamma or TNF-alpha or the type-2 cytokine IL-4 or IL-10 at either the mRNA or protein level.
2713 11024117 No evidence was found for interleukin 4 (IL-4) or IL-5 production by isolated lymphocytes from children or adults.
2714 11024117 In contrast, lymphocytes from convalescent adults produced a typical type 1 response associated with high levels of IL-2 and gamma interferon (IFN-gamma).
2715 11035735 CD4+ alpha beta T cells and gamma interferon (IFN-gamma) are centrally implicated in the primary immunoprotective response.
2716 11035735 We find that a full-strength primary response depends on beta(2)-microglobulin (class I major histocompatibility complex [MHC] and class II MHC and on IFN-gamma and interleukin-6 (IL-6) but not on TAP1, perforin, IL-4, Fas ligand, or inducible nitric oxide synthetase.
2717 11035735 Indeed, MHC class II-deficient and IFN-gamma-deficient mice are as susceptible to primary infection as mice deficient in all alpha beta T cells.
2718 11035735 Strikingly, the requirements for a highly effective alpha beta-T-cell-driven memory response are less stringent, requiring neither IFN-gamma nor IL-6 nor class I MHC.
2719 11042280 We generated monocyte-derived DC from leukapheresis products by using GM-CSF and IL-4 and showed that amongst several known maturation stimuli the cocktail consisting of TNF-alpha+IL-1 beta+IL-6+PGE(2) achieved the highest survival of mature DC.
2720 11042280 The addition of CD40L or TRANCE/RANKL further improved DC survival.
2721 11042288 Additionally, cellular immunity was measured by an increased level of IFN-gamma mRNA detected in PBMC of cattle immunized with the gD gene or with the commercial vaccine, whereas augmented levels of IL-4 were not detected following vaccination.
2722 11046071 When the Ag-induced cytokine responses were examined at both protein and mRNA levels, CD4(+) T cells from spleen and Peyer's patches of young adult mice revealed elevated levels of IL-4 production; however, these cytokine responses were significantly diminished in aged mice.
2723 11054277 Here, pigs were vaccinated by a single coinjection of three plasmids encoding PRV glycoproteins gB, gC, and gD, with plasmid expressing porcine granulocytemacrophage colony-stimulating factor (GM-CSF) or porcine interferon-alpha (IFN-alpha).
2724 11054277 DNA immunization induced a primary T cell-mediated response characterized by low rates of IFN-gamma, interleukin-2 (IL-2), and IL4 mRNA in peripheral blood mononuclear cells (PBMC).
2725 11054277 Codelivery of plasmid expressing GM-CSF or IFN-alpha had no effect on cytokine mRNA expression or on B cell response.
2726 11054277 Codelivery of GMCSF gene significantly increased both Th immune response (i.e., IFN-gamma and IL-4 mRNA expression) and clinical protection but had no effect on secondary B immune response.
2727 11054277 Here, pigs were vaccinated by a single coinjection of three plasmids encoding PRV glycoproteins gB, gC, and gD, with plasmid expressing porcine granulocytemacrophage colony-stimulating factor (GM-CSF) or porcine interferon-alpha (IFN-alpha).
2728 11054277 DNA immunization induced a primary T cell-mediated response characterized by low rates of IFN-gamma, interleukin-2 (IL-2), and IL4 mRNA in peripheral blood mononuclear cells (PBMC).
2729 11054277 Codelivery of plasmid expressing GM-CSF or IFN-alpha had no effect on cytokine mRNA expression or on B cell response.
2730 11054277 Codelivery of GMCSF gene significantly increased both Th immune response (i.e., IFN-gamma and IL-4 mRNA expression) and clinical protection but had no effect on secondary B immune response.
2731 11060692 Allergic individuals respond to an environmental allergen encounter by producing T-cell cytokines, predominantly IL-4 and IL-5, which in turn drive the production of allergen-specific IgE antibodies and recruitment of an eosinophil-rich inflammatory infiltrate.
2732 11075550 Expression of interleukin-1 (IL-1), IL-6, IL-12 and tumour necrosis factor-alpha (TNF-alpha), but not of IL-10, was detected in INMD-stimulated alveolar macrophages.
2733 11075550 Stimulated PBMC expressed IL-1, IL-2, IL-4, IL-6, IL-10 and IL-12 and secreted interferon-gamma (IFN-gamma).
2734 11085581 Macaque fibrocytes displayed the characteristic cellular morphology and stained positive for CD34 and collagen, as observed in human and murine fibrocytes.
2735 11085581 Macaque DCs were generated from monocytes by culturing in granulocyte-macrophage colony stimulating factor and interleukin-4 (IL-4).
2736 11086107 Dendritic cells, infected with vesicular stomatitis virus-pseudotyped HIV-1, present viral antigens to CD4+ and CD8+ T cells from HIV-1-infected individuals.
2737 11086107 The nonreplicating, VSV/HIV-1 efficiently infected the immature stage of DC development, in this case represented by monocytes cultured with GM-CSF and IL-4.
2738 11086107 The infected populations were further matured with CD40 ligand, leading to strong stimulation of autologous T cells from HIV-1-infected individuals, but not controls.
2739 11086107 Enriched CD8(+) T cells from 12/12 donors released IFN-gamma (50-300 enzyme-linked immunospots/200,000 T cells) and proliferated.
2740 11086107 Presentation to CD8(+) T cells, but not to CD4(+), was primarily through an endogenous pathway, because the responses were markedly reduced if envelope-defective virus particles or reverse transcriptase inhibitors were added.
2741 11086107 Therefore, nonreplicating vaccines can be targeted to immature DCs, which upon further maturation induce combined and robust CD4(+) and CD8(+) immunity.
2742 11101874 We found that interleukin 4 receptor (IL-4R) knockout and downstream signal transducer and activator of transcription 6 (STAT6) knockout, but not IL-4 knockout, mice resisted tumor recurrence, which implicated IL-13, the only other cytokine that uses the IL-4R-STAT6 pathway.
2743 11104791 Lymph node cells and CD4(+) T-cell lines raised with CW/M antigen transfer protective immunity when they release type 1 cytokine IFN-gamma, but not when they release IL-4, and neutralization of IFN-gamma confirmed its role in vivo.
2744 11106257 Induction of antitumor immunity with combination of HER2/neu DNA vaccine and interleukin 2 gene-modified tumor vaccine.
2745 11106257 Cytokine-secreting MBT-2 cells were obtained by infecting cells with retroviral particles containing interleukin (IL) 2-, IL-4-, or granulocyte-macrophage colony-stimulating factor (GM-CSF)-expression vector.
2746 11106257 MBT-2-IL-2, -IL-4, and -GM-CSF cells were killed by irradiation and tested as tumor vaccines.
2747 11106257 On the other hand, irradiated MBT-2-IL-4 and MBT-2-GM-CSF cells were less effective.
2748 11106257 Immunohistochemical analysis of tumor infiltrate revealed massive increase of CD4+ lymphoid cells in the group of mice treated with both DNA vaccine and IL-2-secreted tumor vaccine.
2749 11106257 The results indicate the combination of DNA vaccine and IL-2-secreting tumor vaccine can additionally improve therapeutic efficacy, and the efficacy is correlated with the increase of CD4+ T lymphocytes and anti-neu antibody.

2759 11106257 On the other hand, irradiated MBT-2-IL-4 and MBT-2-GM-CSF cells were less effective.
2760 11106257 Immunohistochemical analysis of tumor infiltrate revealed massive increase of CD4+ lymphoid cells in the group of mice treated with both DNA vaccine and IL-2-secreted tumor vaccine.
2761 11106257 The results indicate the combination of DNA vaccine and IL-2-secreting tumor vaccine can additionally improve therapeutic efficacy, and the efficacy is correlated with the increase of CD4+ T lymphocytes and anti-neu antibody.
2762 11106942 This is a simple method that allows reliable determination of the differing regulation of cytokine mRNAs specific for porcine interleukin (IL)-2, -4 and -10, interferon gamma (IFN-gamma) and the housekeeping gene, GAPDH, as an endogenous control.
2763 11106942 The results demonstrated that restimulation with PRV significantly enhanced the transcription of Th1-type cytokines (IL-2 and IFN-gamma) but not of Th2-type cytokines (IL-4 and IL-10).
2764 11106942 Notably, PBMC derived from immune and naive pigs constitutively produced relatively high amounts of IL-10-specific mRNA, exceeding that of GAPDH mRNA, independently of the addition of viral antigen or the mitogen concanavalin A (Con A).
2765 11118387 T helper type 1 (Th1) lymphocytes secrete secrete interleukin (IL)-2, interferon-gamma, and lymphotoxin-alpha and stimulate type 1 immunity, which is characterized by intense phagocytic activity.
2766 11118387 Conversely, Th2 cells secrete IL-4, IL-5, IL-9, IL-10, and IL-13 and stimulate type 2 immunity, which is characterized by high antibody titers.
2767 11119510 Signaling via interleukin-4 receptor alpha chain is required for successful vaccination against schistosomiasis in BALB/c mice.
2768 11119510 We show that in BALB/c mice deficient for the IL-4 receptor alpha chain (IL-4Ralpha(-/-)), which are unresponsive to IL-4 and IL-13, vaccine-induced protection is abrogated compared with that in wild-type (WT) mice.
2769 11119510 In vaccinated IL-4Ralpha(-/-) mice, IL-12p40 production by cells from the skin exposure site was elevated, although gamma interferon (IFN-gamma) production in draining lymphoid tissues was similar in WT and IL-4Ralpha(-/-) mice.
2770 11119510 Nevertheless, the effector response in IL-4Ralpha(-/-) mice was Th1 biased with elevated IFN-gamma in the lungs and higher immunoglobulin G2a (IgG2a) and IgG2b titers but negligible quantities of Th2-associated IgG1 and IgE.
2771 11119510 Interestingly, levels of IL-4 were equivalent in WT and IL-4Ralpha(-/-) mice, indicating that Th2 responses were not dependent upon signaling by IL-4 or IL-13.

2775 11119510 Nevertheless, the effector response in IL-4Ralpha(-/-) mice was Th1 biased with elevated IFN-gamma in the lungs and higher immunoglobulin G2a (IgG2a) and IgG2b titers but negligible quantities of Th2-associated IgG1 and IgE.
2776 11119510 Interestingly, levels of IL-4 were equivalent in WT and IL-4Ralpha(-/-) mice, indicating that Th2 responses were not dependent upon signaling by IL-4 or IL-13.

2781 11119510 Interestingly, levels of IL-4 were equivalent in WT and IL-4Ralpha(-/-) mice, indicating that Th2 responses were not dependent upon signaling by IL-4 or IL-13.
2782 11119511 Amino acid microsequencing of p42 revealed that it consists predominantly of schistosome glyceraldehyde 3-phosphate dehydrogenase (SG3PDH).
2783 11119511 Lymphoproliferation and production of interleukin-4 and gamma interferon (IFN-gamma) after in vitro stimulation with rSG3PDH and serum isotype responses to rSG3PDH were examined in individuals with extremes of resistance and susceptibility to reinfection after treatment of previous S. mansoni or S. haematobium infection.
2784 11119511 Lymphoproliferation and IFN-gamma production in response to rSG3PDH and the presence of serum immunoglobulin G1 (IgG1), IgG3, and IgA antibodies to rSG3PDH generally characterized individuals who are resistant to reinfection after chemotherapy.
2785 11122109 In these five patients, detection of cytokines by real-time reverse transcription polymerase chain reaction (RT-PCR) revealed that granulocyte-macrophage colony-stimulating factor (GM-CSF) was the most abundant cytokine gene expressed by the T cells that recognized the autologous tumour B cells.
2786 11122109 Other activated cytokine genes were gamma-interferon (IFN), interleukin (IL)-2 and tumour necrosis factor (TNF)-alpha, but not IL-4.
2787 11122109 CD80 and CD54 were relatively downregulated on the native tumour B cells compared with control normal B cells.
2788 11122109 CD80 and CD54 monoclonal antibodies inhibited the specific T-cell DNA synthesis proliferation.
2789 11122109 The specific cytokine gene expression could be found in isolated CD4, as well as CD8, T-cell subsets.
2790 11122109 This study demonstrated the presence of a potential natural specific CD4, as well as a CD8 type 1 T-cell immunity against the leukaemic CLL tumour B cells in CLL.
2791 11128522 Culture supernatants of splenocytes from immune DBA/2 mice, which were stimulated with crude C. ruminantium antigens or recombinant major antigenic proteins 1 or 2, contained significant levels of interferon (IFN)-gamma and interleukin (IL)-6, but insignificant levels of IL-1alpha, IL-2, IL-4, IL-5, IL-10, IL-12, tumor necrosis factor-alpha (TNF), and nitric oxide.
2792 11133829 Pretreatment of mice with CpG ODN mixed with rAed a 2 successfully inhibited subsequent induction of serum rAed a 2-specific IgE (but not IgG1) and antigen-induced IL-4 and IL-5 production in spleen cells.
2793 11133829 This was associated with an increase of serum IgG2a and IL-12, and increased IFN-gamma and IL-12 production by spleen cells.
2794 11134269 The CC chemokines macrophage inflammatory protein 1beta (MIP-1beta) and monocyte chemotactic protein 1 (MCP-1) biased the immunity to the Th2-type pattern as judged by the ratio of immunoglobulin isotypes and interleukin-4 cytokine levels produced by CD4(+) T cells.
2795 11134269 The CXC chemokine MIP-2 and the CC chemokine MIP-1alpha, however, mounted immune responses of the Th1-type pattern, and such a response rendered recipients more resistant to HSV vaginal infection.
2796 11134269 In addition, MIP-1alpha appeared to act via the upregulation of antigen-presenting cell (APC) function and the expression of costimulatory molecules (B7-1 and B7-2), whereas MIP-2 enhanced Th1-type CD4(+) T-cell-mediated adaptive immunity by increasing gamma interferon secretion from activated NK cells.
2797 11134279 Role of interleukin-4 (IL-4), IL-12, and gamma interferon in primary and vaccine-primed immune responses to Friend retrovirus infection.
2798 11134279 The immunological resistance of a host to viral infections may be strongly influenced by cytokines such as interleukin-12 (IL-12) and gamma interferon (IFN-gamma), which promote T helper type 1 responses, and IL-4, which promotes T helper type 2 responses.
2799 11134279 IL-4- and IL-12-deficient mice were comparable to wild-type B6 mice in the ability to control acute and persistent Friend virus infections.
2800 11134279 Role of interleukin-4 (IL-4), IL-12, and gamma interferon in primary and vaccine-primed immune responses to Friend retrovirus infection.
2801 11134279 The immunological resistance of a host to viral infections may be strongly influenced by cytokines such as interleukin-12 (IL-12) and gamma interferon (IFN-gamma), which promote T helper type 1 responses, and IL-4, which promotes T helper type 2 responses.

2803 11134279 Role of interleukin-4 (IL-4), IL-12, and gamma interferon in primary and vaccine-primed immune responses to Friend retrovirus infection.
2804 11134279 The immunological resistance of a host to viral infections may be strongly influenced by cytokines such as interleukin-12 (IL-12) and gamma interferon (IFN-gamma), which promote T helper type 1 responses, and IL-4, which promotes T helper type 2 responses.
2805 11134279 IL-4- and IL-12-deficient mice were comparable to wild-type B6 mice in the ability to control acute and persistent Friend virus infections.
2806 11137237 Gene gun delivery of DNA-F elicited a T helper-2 (Th2) biased immune response that could not be modulated by the co-delivery of plasmids encoding IL-2, IL-12 or IFNgamma.
2807 11137237 Thus, all gene gun vaccinated mice produced a predominant Th2 biased pulmonary immune response characterised by the production of IL-4 and IL-5 with little IFNgamma following RSV challenge.
2808 11140881 Following culture in cytokines GM-CSF/IL-4/CD40L, which induced differentiation of AML blasts to dendritic-like cells, transduction efficiency was increased between two- and eightfold in 6 out of the 15 cases that underwent differentiation.
2809 11145673 The protection appeared to be mediated by IFN-gamma and CD8(+) cells because treatment of mice with neutralizing anti-IFN-gamma mAb or with depleting anti-CD8 mAb abolished the protective effect.
2810 11145673 Moreover, vaccination of mice with preexisting AHR with the OVA-IL-18 fusion DNA, but not with the OVA cDNA plasmid, reversed established AHR, reduced allergen-specific IL-4, and increased allergen-specific IFN-gamma production.
2811 11145714 Mutations in the common gamma-chain (gamma(c)) of cytokine receptors, including those for IL-2, IL-4, IL-7, IL-9, and IL-15, are responsible for an X-linked form of the disease, while mutations of several other genes, including Janus-associated kinase-3, may cause autosomal recessive forms of SCID.
2812 11145714 We report here that a homozygous 6-bp deletion in the gene encoding CD45 (PTPRC, gene map locus 1q31-32), which results in a loss of glutamic acid 339 and tyrosine 340 in the first fibronectin type III module of the extracellular domain of CD45, is associated with failure of surface expression of CD45 and SCID.
2813 11145720 Numerous immunostimulatory protocols inhibit the development of T cell-mediated autoimmune insulin-dependent diabetes mellitus (IDDM) in the nonobese diabetic (NOD) mouse model.
2814 11145720 Many of these protocols, including treatment with the nonspecific immunostimulatory agents CFA or bacillus Calmette-Guérin (BCG) vaccine, have been reported to mediate protection by skewing the pattern of cytokines produced by pancreatic beta-cell autoreactive T cells from a Th1 (IFN-gamma) to a Th2 (IL-4 and IL-10) profile.
2815 11145720 To partially address this issue we produced NOD mice genetically deficient in IFN-gamma, IL-4, or IL-10.
2816 11145720 Additional experiments using these mice confirmed that CFA- or BCG-elicited diabetes protection is associated with a decreased IFN-gamma to IL-4 mRNA ratio within T cell-infiltrated pancreatic islets, but this is a secondary consequence rather than the cause of disease resistance.
2817 11145720 Unexpectedly, we also found that the ability of BCG and, to a lesser extent, CFA to inhibit IDDM development in standard NOD mice is actually dependent upon the presence of the Th1 cytokine, IFN-gamma.

2828 11145848 We have studied the ability of this OMV vaccine preparation to induce secretion of pro-inflammatory cytokines, tumour necrosis factor alpha (TNF-alpha), interleukin 1beta (IL-1beta), interleukin 6 (IL-6), interleukin 8 (IL-8) and anti-inflammatory cytokines, interleukin 4 (IL-4), interleukin 10 (IL-10) and interleukin 13 (IL-13) in a human whole blood model.
2829 11145848 Plasma levels of TNF-alpha, IL-1beta, IL-6 and IL-8 were massively increased; mean peak levels of TNF-alpha 44 696+/-7764, IL-1beta 38 043+/-5411, IL-6 10 057+/-1619 and IL-8 30 449+/-5397 pg/ml were obtained with an OMV-LPS concentration of 1 microg/ml; corresponding levels in control plasmas were below the detection limit of the assay.
2830 11145848 OMV-LPS did not induce release of IL-4 and IL-13 in doses from 0.001-10 microg/ml.

2833 11145848 OMV-LPS did not induce release of IL-4 and IL-13 in doses from 0.001-10 microg/ml.
2834 11150544 We demonstrated significant correlations of cytokine mRNA and protein expression for TNF alpha, IL10, and IFN gamma.
2835 11150544 Expression of IL2 mRNA at 16 h was correlated with proliferation indices at 96 h whereas IL4 mRNA levels were negatively correlated.
2836 11160013 Thus, flow cytometry analyses showed an increase in the expression of major histocompatibility complex (MHC) class II, CD40, CD54, CD58, CD83, and CD86 molecules on the monocytes.
2837 11160013 The increase in cell surface expression of MHC class II did not occur in the presence of neutralizing IL-4 antibody or in cultures of highly purified monocytes or CD4-depleted mononuclear cells.
2838 11160013 Activated Th2 cells release IL-4, which in turn can induce an increase in the expression of MHC class II molecules on monocytes.

2842 11160264 In this study, we have investigated the use of plasmid DNA (pDNA) vaccination to elicit Th2 effector cell function in an Ag-specific manner and in turn prevent insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice. pDNA recombinants were engineered encoding a secreted fusion protein consisting of a fragment of glutamic acid decarboxylase 65 (GAD65) linked to IgGFc, and IL-4.
2843 11160264 Intramuscular injection of pDNA encoding GAD65-IgGFc and IL-4 effectively prevented diabetes in NOD mice treated at early or late preclinical stages of IDDM.
2844 11160264 This protection was GAD65-specific since NOD mice immunized with pDNA encoding hen egg lysozyme-IgGFc and IL-4 continued to develop diabetes.
2845 11160264 Importantly, GAD65-specific immune deviation was dependent on pDNA-encoded IL-4.

2862 11160664 As for Ctx-CtxB, rEtxB resulted in a Th2-biased immune response with high immunoglobulin G1 (IgG1)/IgG2a antibody ratios and production of interleukin 4 (IL-4) and IL-10 as well as gamma interferon by proliferating T cells.
2863 11164109 To optimize antigen pulsing of DCs, we investigated mechanisms of antigen uptake and evaluated various laboratory parameters including class of myeloma protein, antigen exposure time, and DC maturational stage.DCs were generated by culturing peripheral blood stem cells from myeloma patients in granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4).
2864 11165924 Cells from susceptible L. amazonensis-infected CBA mice produced interleukin (IL)-4 and IL-10 but no interferon (IFN)-gamma.
2865 11165924 On the other hand, resistant L. major-infected CBA mice produced IFN-gamma and IL-10, but IL-4 was detected only in the first week of infection.
2866 11165924 Cells from susceptible L. amazonensis-infected CBA mice produced interleukin (IL)-4 and IL-10 but no interferon (IFN)-gamma.
2867 11165924 On the other hand, resistant L. major-infected CBA mice produced IFN-gamma and IL-10, but IL-4 was detected only in the first week of infection.
2868 11166891 Numerous antigen-specific T cells synthesising IFN-gamma (Th1) and IL-4 (Th2) were detectable using both intracellular staining and ELISPOT assays.
2869 11166908 The data showed a concomitant expression of interleukin (IL)-4 and interferon-gamma in PBMC of vaccinated foxes.
2870 11166908 No change was detected in the level of IL-2, IL-10 and IL-12 synthesis, whereas the pro-inflammatory cytokine tumour necrosis factor-alpha seemed involved in the activation of naive T lymphocytes.
2871 11207323 Splenocytes recovered at 5-6 mo after the last DNA administration exhibited a sustained IFN-gamma and IL-10 secretion and reduced IL-4 production.
2872 11207323 Recall challenge with PLA(2) boosted IFN-gamma and IL-10 secretion, suggesting the reactivation of quiescent memory Th1 lymphocytes.
2873 11228534 IL-12 DNA administration induces long-lasting systemic IFN -gamma production, whereas IL-4 and TNF-alpha levels remained undetectable.
2874 11233801 Bacillus Calmette-Guerin down-regulates CD1b induction by granulocyte-macrophage colony stimulating factor in human peripheral blood monocytes.
2875 11233801 Since vaccination with Bacillus Calmette-Guerin (BCG) has limited efficacy, the influence of viable BCG organisms on the induction of CD1b antigen by granulocyte macrophage-colony stimulating factor (GM-CSF) has been tested in adherent mononuclear cells obtained from peripheral blood of healthy donors.
2876 11233801 The results indicate that the vaccine reduces substantially CD1b induction by GM-CSF.
2877 11233801 Attempts to reverse the antagonistic effects of BCG on GM-CSF with high concentrations of GM-CSF, alone, or associated with IL-4, were unsuccessful.
2878 11233843 A new approach reveals that the largest cytokine change in tuberculosis is a 1-2 log increase in copy number for mRNAs encoding IL-4 and IL-13, accompanied by a small decrease in expression of mRNA encoding interferon-gamma.
2879 11238201 Up-regulation of CD40 ligand and induction of a Th2 response in children immunized with pneumococcal polysaccharide vaccines.
2880 11238201 We wished to determine whether pneumococcal polysaccharide antigens induce mRNA expression of CD40 ligand (CD40L) and Th1 or Th2 cytokines in unimmunized individuals in vitro and whether immunization with the 23-valent pneumococcal polysaccharide vaccine induces changes in CD40L and cytokine mRNA expression.
2881 11238201 Quantification of mRNA expression of CD40L, interleukin-4 (IL-4), IL-12p40, and gamma interferon (IFN-gamma) was performed by reverse transcription-PCR and enzyme-linked immunosorbent assay (ELISA)-PCR with resting and stimulated peripheral blood mononuclear cells.
2882 11238201 The results showed a significant increase in the expression of mRNAs for CD40L and IL-4, but not IL-12p40 or IFN-gamma, in stimulated cultures from unimmunized individuals.
2883 11238201 CD40L and IL-4 mRNA expression was significantly higher in postimmunization than in preimmunization samples stimulated with the individual pneumococcal serotypes.
2884 11238201 Up-regulation of CD40 ligand and induction of a Th2 response in children immunized with pneumococcal polysaccharide vaccines.

2886 11238201 Quantification of mRNA expression of CD40L, interleukin-4 (IL-4), IL-12p40, and gamma interferon (IFN-gamma) was performed by reverse transcription-PCR and enzyme-linked immunosorbent assay (ELISA)-PCR with resting and stimulated peripheral blood mononuclear cells.
2887 11238201 The results showed a significant increase in the expression of mRNAs for CD40L and IL-4, but not IL-12p40 or IFN-gamma, in stimulated cultures from unimmunized individuals.
2888 11238201 CD40L and IL-4 mRNA expression was significantly higher in postimmunization than in preimmunization samples stimulated with the individual pneumococcal serotypes.
2889 11238201 Up-regulation of CD40 ligand and induction of a Th2 response in children immunized with pneumococcal polysaccharide vaccines.
2890 11238201 We wished to determine whether pneumococcal polysaccharide antigens induce mRNA expression of CD40 ligand (CD40L) and Th1 or Th2 cytokines in unimmunized individuals in vitro and whether immunization with the 23-valent pneumococcal polysaccharide vaccine induces changes in CD40L and cytokine mRNA expression.
2891 11238201 Quantification of mRNA expression of CD40L, interleukin-4 (IL-4), IL-12p40, and gamma interferon (IFN-gamma) was performed by reverse transcription-PCR and enzyme-linked immunosorbent assay (ELISA)-PCR with resting and stimulated peripheral blood mononuclear cells.
2892 11238201 The results showed a significant increase in the expression of mRNAs for CD40L and IL-4, but not IL-12p40 or IFN-gamma, in stimulated cultures from unimmunized individuals.
2893 11238201 CD40L and IL-4 mRNA expression was significantly higher in postimmunization than in preimmunization samples stimulated with the individual pneumococcal serotypes.
2894 11238679 Following enrichment, DC developed an activated phenotype with up-regulation of CD80, CD86, and CD83 expression.
2895 11238679 During culture, the DC maintained their levels of various adhesion molecules, including CD44, LFA-1, cutaneous lymphocyte-associated Ag, and CD49d, up-regulated CCR7, but lost CD62 ligand and CCR5.
2896 11238679 Induction of IFN-gamma production, however, was seen only with i.d. and i.l. routes of administration, and no IL-4 responses were seen regardless of route, consistent with the induction of Th1-type immunity.
2897 11248075 Higher levels of CD4(+) T-cell-derived IFN-gamma, IL-4, IL-5, and IL-10 syntheses were noted in Peyer's patch-null mice fed OVA, whereas OVA-fed normal mice had suppressed cytokine levels.
2898 11248361 Prophylactic administration of HSV-2 ISCOM vaccine to mice elicits local antibody detectable in nasal washings, serum antibody and the presence of cytokines IL-2, IFN-gamma and IL-4 in supernatants from spleen cell cultures stimulated in vitro with HSV-2 antigens.
2899 11248361 Treatment of HSV-2 infected mice with the HSV-2 ISCOM vaccine also induces higher levels of the cytokines IL-2, IFN-gamma and IL-4, in in vitro stimulated spleen cell cultures.
2900 11248361 Prophylactic administration of HSV-2 ISCOM vaccine to mice elicits local antibody detectable in nasal washings, serum antibody and the presence of cytokines IL-2, IFN-gamma and IL-4 in supernatants from spleen cell cultures stimulated in vitro with HSV-2 antigens.
2901 11248361 Treatment of HSV-2 infected mice with the HSV-2 ISCOM vaccine also induces higher levels of the cytokines IL-2, IFN-gamma and IL-4, in in vitro stimulated spleen cell cultures.
2902 11251876 Both LT and CT induce B7-2 expression on antigen-presenting cells (APCs) for subsequent co-stimulatory signalling to CD4+ T cells.
2903 11251876 CT directly affects CD4+ T cells activated via the TCR-CD3 complex with selective inhibition of Th1 responses whereas LT maintains Th1 cytokine responses with inhibition of interleukin (IL)-4 production.
2904 11251876 Nontoxic mutant (m)CTs (S61F and E112K) retain adjuvant properties by inducing CD4+ Th2 cells, which provided effective help for the Ag-specific mucosal immunoglobulin (Ig)A, as well as serum IgG1, IgE and IgA Ab responses.
2905 11251876 Firstly, mCT enhanced the B7-2 expression of APCs.
2906 11254580 The characteristic interleukin 4 (IL-4) switch that occurs in the CD4 T-cell population after an acute blood stage P. c. chabaudi infection was only consistently observed in the response to the amino acid 900 to 1507 MSP1 fragment.
2907 11257383 Modulation of antigen-specific cellular immune responses to DNA vaccination in rhesus macaques through the use of IL-2, IFN-gamma, or IL-4 gene adjuvants.
2908 11257383 We co-immunized rhesus macaques with expression plasmids encoding for IL-2, IFN-gamma or IL-4 cytokines along with the DNA vaccine constructs encoding for HIV env/rev (pCEnv) and SIV gag/pol (pCSGag/pol) proteins.
2909 11257383 We observed that coadministration of IL-2 and IFN-gamma cDNA resulted in enhancement of antigen-specific T cell-mediated immune responses.
2910 11257383 Modulation of antigen-specific cellular immune responses to DNA vaccination in rhesus macaques through the use of IL-2, IFN-gamma, or IL-4 gene adjuvants.
2911 11257383 We co-immunized rhesus macaques with expression plasmids encoding for IL-2, IFN-gamma or IL-4 cytokines along with the DNA vaccine constructs encoding for HIV env/rev (pCEnv) and SIV gag/pol (pCSGag/pol) proteins.
2912 11257383 We observed that coadministration of IL-2 and IFN-gamma cDNA resulted in enhancement of antigen-specific T cell-mediated immune responses.
2913 11257386 Oral immunisation with the blastospore yeast form (but not subcutaneous immunisation) induced clinical immunity, with a shift in parameters of cytokine response characterised by an early and sustained production of both IFN-gamma and IL-4 from antigen-stimulated cervical node T lymphocytes.
2914 11260324 In order to address this issue a murine melanoma cell line (K1735) was transfected to secrete interleukin (IL)-2, IL-4, IL-7 or granulocyte-macrophage colony-stimulating factor (GM-CSF); cytokines currently in use in trials.
2915 11260324 Anti-tumour cytotoxic T-lymphocyte (CTL) activity was detected in both models but did not correlate well with protection, whilst in vitro anti-tumour interferon-gamma (IFN-gamma) secretion tended to be higher following the GM-CSF-secreting vaccine.
2916 11269272 These studies showed a significant increase in the levels of IL-4 and IL-10 message in the skin in areas of cercarial penetration.
2917 11269272 The IL-4 message was detectable in the skin as early as 8 h after infection and the message for IL-10 appeared from 16 h after infection.
2918 11269272 In sharp contrast, vaccination with irradiated cercariae induced IFN-gamma and IL-2 responses in the skin within 24 h.
2919 11269272 Analysis of the cytokine profile of cells isolated from the skin during these early time points showed that T cells are probably not a source of IL-4 or IL-10 in the skin of mice infected with normal cercariae.
2920 11269272 Analysis of the CD4/CD8 ratio showed a significant decrease in the skin following vaccination suggesting an increase in CD8+ cells.
2921 11269272 These studies showed a significant increase in the levels of IL-4 and IL-10 message in the skin in areas of cercarial penetration.
2922 11269272 The IL-4 message was detectable in the skin as early as 8 h after infection and the message for IL-10 appeared from 16 h after infection.
2923 11269272 In sharp contrast, vaccination with irradiated cercariae induced IFN-gamma and IL-2 responses in the skin within 24 h.
2924 11269272 Analysis of the cytokine profile of cells isolated from the skin during these early time points showed that T cells are probably not a source of IL-4 or IL-10 in the skin of mice infected with normal cercariae.
2925 11269272 Analysis of the CD4/CD8 ratio showed a significant decrease in the skin following vaccination suggesting an increase in CD8+ cells.
2926 11269272 These studies showed a significant increase in the levels of IL-4 and IL-10 message in the skin in areas of cercarial penetration.
2927 11269272 The IL-4 message was detectable in the skin as early as 8 h after infection and the message for IL-10 appeared from 16 h after infection.
2928 11269272 In sharp contrast, vaccination with irradiated cercariae induced IFN-gamma and IL-2 responses in the skin within 24 h.
2929 11269272 Analysis of the cytokine profile of cells isolated from the skin during these early time points showed that T cells are probably not a source of IL-4 or IL-10 in the skin of mice infected with normal cercariae.
2930 11269272 Analysis of the CD4/CD8 ratio showed a significant decrease in the skin following vaccination suggesting an increase in CD8+ cells.
2931 11269323 Furthermore, these levels were increased by the coinoculation of cytokine (IFN-gamma, IL-4, GM-CSF, or IL-12) expression plasmid.
2932 11269323 In respect to the SERA-specific Ig subclasses, coinoculation of IFN-gamma, GM-CSF, or IL-12 expression plasmid increased the levels of SERA-specific IgG2a, and these were much higher than that in mice immunized with SERA expression plasmid alone.
2933 11282190 Intramuscular injection of mixed DNA constructs encoding for HIV-1 Gag, Tat and Nef proteins, co-administered with the DNA encoding for interleukin-18 (IL-18) have been used.
2934 11282190 It was demonstrated that at least two DNA immunizations were necessary to generate virus specific Th-1 responses detected by the presence of cytotoxic T lymphocyte (CTL) and by the secretion of IL-2 and IFN-gamma, but not IL-4 and IL-10, in antigen-stimulated splenocyte cultures.
2935 11282190 Interestingly, co-delivery of Th-1-inducing IL-18 gene was able to shorten by 2 weeks, the CTL induction time, and to increase the antigen-induced secretion of IL-2 and IFN-gamma.
2936 11282206 These findings are supported by a high interferon-gamma but a low interleukin-4 level detected in the supernatant of splenic cell cultures obtained from mucosally immunized mice.
2937 11282986 Differential effect of CD8(+) and CD8(-) dendritic cells in the stimulation of secondary CD4(+) T cells.
2938 11282986 Subsets of mature murine DC isolated directly from the spleen have been shown to differ in their ability to induce proliferative responses in both primary CD4(+) and primary CD8(+) T cells; the myeloid-related CD8alpha(-) DC induce a more intense or prolonged proliferation of naive T cells than do the lymphoid-related DC bearing CD8alpha despite similar expression of MHC and co-stimulatory molecules.
2939 11282986 We show that influenza virus-specific CD4(+) T cell clones and splenic T cells from peptide-primed animals proliferated in response to antigen presented by separated splenic CD8(-) DC.
2940 11282986 The differential between the two DC types in inducing proliferation was even more pronounced than previously seen with primary T cells and did not reflect differential longevity of the DC in culture, altered response kinetics or deviation from IL-2 to IL-4 induction with CD8(+) DC, but was related to the levels of IL-2 induced.
2941 11282986 These results show that lymphoid-related CD8(+) splenic DC, despite their mature phenotype, fail to provide appropriate signals to secondary CD4(+) T cells to sustain their proliferation.
2942 11283156 B7-DC fails to bind the B7.1/2 receptors CD28 and cytotoxic T lymphocyte-associated antigen (CTLA)-4, but does bind PD-1, a receptor for B7-H1/PD-L1.
2943 11283156 In particular, B7-DC strongly costimulates interferon gamma but not interleukin (IL)-4 or IL-10 production from isolated naive T cells.
2944 11285124 Cell-mediated responses were analyzed on days 0, 14 and 28 after vaccination by measuring lymphocyte proliferation and production of interferon (IFN)-gamma (Th1 marker) or interleukin (IL)-4 and IL-5 (Th2 markers) cytokines after in vitro stimulation with the PS and protein components of the vaccines.
2945 11300494 A majority of the patients had reduced TCRzeta chain expression and interleukin 4 production by T cells, and all of the patients showed decreased production of IFN-gamma of their peripheral T cells when compared with healthy individuals.
2946 11313269 In this study, blasts from 40 patients with acute myeloid leukemia (AML) were cultured with combinations of granulocyte-macrophage colony-stimulating factor, interleukin 4, and tumor necrosis factor alpha, and development to DCs was assessed.
2947 11313269 After culture, cells from 24 samples exhibited morphological and immunophenotypic features of DCs, including expression of major histocompatibility complex class II, CD1a, CD83, and CD86, and were potent stimulators in an allogeneic mixed lymphocyte reaction (MLR).
2948 11313782 We previously found that recombinant vaccinia and naked DNA vaccines containing the chimeric Sig/E7/LAMP-1 gene were capable of controlling the growth of HPV-16 E7-expressing tumor cells (TC-1).
2949 11313782 At a dose of 1 x 10(6) TC-1 cells per mouse, Sig/E7/LAMP-1 DNA provided 100% protection against subcutaneous growth of tumors, while Vac-Sig/E7/LAMP-1 protected only 40% of the mice.
2950 11313782 Furthermore, Sig/E7/LAMP-1 DNA vaccines are capable of protecting against challenge with a more stringent subclone of TC-1 (TC-1 P2) established from TC-1 tumors that survived initial Sig/E7/LAMP-1 vaccinia vaccination.
2951 11313782 Interestingly, Sig/E7/LAMP-1 vaccinia induced both E7-specific IFN-gamma- and IL4-secreting CD4(+) T cell precursors while Sig/E7/LAMP-1 DNA induced only E7-specific IFN-gamma-secreting CD4(+) T cell precursors.
2952 11313782 We also found that IL-4 knockout C57BL/6 mice vaccinated with Sig/E7/LAMP-1 vaccinia exhibited a more potent antitumor effect than vaccinated wild-type C57BL/6 mice in our tumor protection experiments.
2953 11313782 We previously found that recombinant vaccinia and naked DNA vaccines containing the chimeric Sig/E7/LAMP-1 gene were capable of controlling the growth of HPV-16 E7-expressing tumor cells (TC-1).
2954 11313782 At a dose of 1 x 10(6) TC-1 cells per mouse, Sig/E7/LAMP-1 DNA provided 100% protection against subcutaneous growth of tumors, while Vac-Sig/E7/LAMP-1 protected only 40% of the mice.
2955 11313782 Furthermore, Sig/E7/LAMP-1 DNA vaccines are capable of protecting against challenge with a more stringent subclone of TC-1 (TC-1 P2) established from TC-1 tumors that survived initial Sig/E7/LAMP-1 vaccinia vaccination.
2956 11313782 Interestingly, Sig/E7/LAMP-1 vaccinia induced both E7-specific IFN-gamma- and IL4-secreting CD4(+) T cell precursors while Sig/E7/LAMP-1 DNA induced only E7-specific IFN-gamma-secreting CD4(+) T cell precursors.
2957 11313782 We also found that IL-4 knockout C57BL/6 mice vaccinated with Sig/E7/LAMP-1 vaccinia exhibited a more potent antitumor effect than vaccinated wild-type C57BL/6 mice in our tumor protection experiments.
2958 11321239 As a correlate, interleukin-4 (IL-4) production significantly decreased and interferon-gamma (IFN-gamma) slightly increased, resulting in a markedly decreased ratio of IL-4-IFN-gamma in OVA-presensitized rats with BCG infection.
2959 11334498 In vitro, both activate signal transduction pathways that result in the expression of cytokines, particularly of IL-4 and IFNgamma.
2960 11348719 Protective procedures elicited high frequencies of antigen-reactive alphabeta T cells with CD4+/CD8- and CD8+/CD4- phenotypes.
2961 11348719 Protection correlated with the abundance of hsp65-dependent cytotoxic CD8+/CD4-/CD44hi cells.
2962 11348719 IFN-gamma predominated over IL-4 among the hsp65-reactive CD8+/CD4- and CD4+/CD8- populations after J774-hsp65-, hsp65-liposome-, and hsp65-DNA-mediated immunizations, but similar levels of these cytokines prevailed after BCG vaccination.
2963 11371766 Similarly the demonstration of a very large relative increase in interleukin (IL)-4 and IL-13 expression, (together with IL-4delta2, the IL-4 splice variant), that correlates with lung damage, has been supported by data from flow cytometry and in situ hybridization, and indicates that a subversive T helper-2 (Th2) component in the response to M. tuberculosis may undermine the efficacy of immunity and contribute to immunopathology.
2964 11395213 Furthermore, Vaxfectin had no effect on IFN-gamma or IL-4 production by splenocytes re-stimulated with antigen, suggesting that the Th1 type responses typical of intramuscular pDNA immunization were not altered.
2965 11401992 The presence of gamma interferon IFN-gamma and interleukin-2 (IL-2) mRNAs but absence of IL-4, IL-5, and IL-10 mRNAs were observed in peripheral blood mononuclear cells from immunized subjects after in vitro challenge with outer membrane vesicles.
2966 11418309 In vivo transfection and/or cross-priming of dendritic cells following DNA and adenoviral immunizations for immunotherapy of cancer--changes in peripheral mononuclear subsets and intracellular IL-4 and IFN-gamma lymphokine profile.
2967 11418309 One approach is to genetically manipulate tumor cells to either secrete lymphokines (GM-CSF, IL-12, IL-15) or express membrane bound molecules (CD80, CD86).
2968 11418309 We have successfully completed a phase I and phase II clinical trials on immunotherapy of prostate cancer using naked DNA and adenoviral immunizations against the prostate-specific membrane antigen (PSMA) and phase I clinical trial on colorectal cancer using naked DNA immunization against the carcinoembryonic antigen (CEA).
2969 11418677 Lymphocyte trafficking in the gastrointestinal tract is primarily mediated by interactions with the mucosal addressin cell adhesion molecule 1 and its lymphocyte ligand, alpha(4)beta(7), and partly by L-selectin (L-Sel) interactions with peripheral node addressin coexpressed on some mucosal addressin cell adhesion molecule 1.
2970 11418677 L-Sel(-/-) Peyer's patch (PP) CD4(+) Th cells revealed IFN-gamma-dominated responses and an unprecedented absence of IL-4, whereas the expected mixed Th cell phenotype developed in L-Sel(+/+) mice.
2971 11418698 We previously demonstrated that administration of plasmid DNAs (pDNAs) encoding IL-4 and a fragment of glutamic acid decarboxylase 65 (GAD65) fused to IgGFc induces GAD65-specific Th2 cells and prevents insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice.
2972 11418698 Insulin was chosen based on studies demonstrating that administration of insulin or insulin B chain by a variety of strategies prevents IDDM in NOD mice.
2973 11418698 Surprisingly, young NOD mice receiving i.m. injections of pDNA encoding insulin B chain-IgGFc with or without IL-4 exhibited an accelerated progression of insulitis and developed early diabetes.
2974 11418698 Exacerbation of IDDM correlated with an increased frequency of IFN-gamma-secreting CD4(+) and CD8(+) T cells in response to insulin B chain-specific peptides compared with untreated mice.
2975 11418698 In contrast, treatment with pDNAs encoding insulin A chain-IgGFc and IL-4 elicited a low frequency of IL-4-secreting Th cells and had no effect on the progression of IDDM.
2976 11418698 Vaccination with pDNAs encoding GAD65-IgGFc and IL-4, however, prevented IDDM.
2977 11418698 These results demonstrate that insulin- and GAD65-specific T cell reactivity induced by pDNA vaccination has distinct effects on the progression of IDDM.

2996 11418698 In contrast, treatment with pDNAs encoding insulin A chain-IgGFc and IL-4 elicited a low frequency of IL-4-secreting Th cells and had no effect on the progression of IDDM.
2997 11418698 Vaccination with pDNAs encoding GAD65-IgGFc and IL-4, however, prevented IDDM.

3000 11427282 Co-delivery of the EG95 DNA vaccine with DNA encoding GM-CSF enhanced the antibody titre to EG95 while co-delivery of IFN-gamma or IL-4 encoding DNA appeared to reduce the ability of the DNA vaccine to prime an IgG antibody response.
3001 11427282 A large-scale DNA vaccination trial was performed in sheep to investigate whether co-delivery of the cytokine genes IL-4, IL-5, IL-15, GM-CSF or IFN-gamma could modulate the immune response generated to an antigen, in a DNA prime-recombinant protein boost regime.
3002 11427282 Co-delivery of the EG95 DNA vaccine with DNA encoding GM-CSF enhanced the antibody titre to EG95 while co-delivery of IFN-gamma or IL-4 encoding DNA appeared to reduce the ability of the DNA vaccine to prime an IgG antibody response.

3010 11447143 We demonstrate here that although the LACK DNA vaccine induced a robust parasite-specific Th1 immune response (IFN-gamma but not IL-4 production) and primed for an in vivo T-cell response to inoculated parasites, it did not induce protection against cutaneous or systemic L. donovani challenge.
3011 11447158 Our results confirmed that DNA immunization with pXJ38 induces strong CD8(+) CTL and Th1 responses (high gamma interferon [IFN-gamma], low interleukin-4 [IL-4]).
3012 11447158 Small or undetectable amounts of IL-4 were observed, which indicates the induction of a Th1-like response.

3014 11447158 Small or undetectable amounts of IL-4 were observed, which indicates the induction of a Th1-like response.
3015 11454067 C57Bl/6 mice immunized with this vaccine developed a strong T helper 1 (Th1) response characterized by an increased production of interferon-gamma (IFN-gamma) secreted by CD4+ T cells.
3016 11454067 Neutralization of IL-6 during in vivo priming resulted in marked reduction in the ability of T cells to secrete IFN-gamma and IL-2 and to proliferate.
3017 11454067 IL-6 gene-disrupted mice primed with the vaccine showed a decrease in the number of IFN-gamma-producing cells and an increase in IL-4-secreting cells as compared to control mice.
3018 11454067 In contrast, neutralization of IL-6 during a boost of the vaccine in previously primed mice did not affect the development of IFN-gamma-producing cells but still increased the number of IL-4-producing cells.
3019 11454067 C57Bl/6 mice immunized with this vaccine developed a strong T helper 1 (Th1) response characterized by an increased production of interferon-gamma (IFN-gamma) secreted by CD4+ T cells.

3024 11457534 Intramuscular injection of C57BL/6 mice with the pOVA/IL-18 DNA efficiently increased the production of both OVA-specific IFN-gamma and anti-OVA IgG2a isotype, compared with the injection with the pOVA DNA.
3025 11457534 In addition, the pOVA/IL-18 was more efficient than a simple mixture of pOVA and pIL-18 in inducing antigen-specific, Th1 immune responses and in inhibiting OVA-specific, IL-4 production.

3028 11465110 Infants and adults produced only low concentrations of IL-4 and IL-5.
3029 11465110 CD4+ T lymphocytes were the main source of IFN-gamma.
3030 11465110 This study demonstrates that the human neonatal immune response to BCG is not biased towards Th2 and is characterized by the predominant production of IFN-gamma by CD4+ T lymphocytes.
3031 11485734 We also show that DNA vaccines can be used to reverse established EAE by covaccination with the genes for myelin oligodendrocyte glycoprotein and IL-4.

3038 11500439 HLA DRB1* allele-dependent IFN-gamma expression was identified only in controls, suggesting a skewing of the immune response in patients.
3039 11500439 In contrast to the case for IFN-gamma, only some patients and controls expressed IL-4 or IL-10 (Th2 profile); thus, the Th1 profile was identifiable only by a nonexpression of IL-4 or IL-10 in this area of endemicity.
3040 11500439 To elaborate these ideas, we studied gamma interferon (IFN-gamma), interleukin-4 (IL-4), and IL-10 cytokine expression in 71 adult pulmonary tuberculosis patients and 74 controls from areas of endemicity in south India by 48-h microculture and reverse transcription-PCR.
3041 11500439 HLA DRB1* allele-dependent IFN-gamma expression was identified only in controls, suggesting a skewing of the immune response in patients.
3042 11500439 In contrast to the case for IFN-gamma, only some patients and controls expressed IL-4 or IL-10 (Th2 profile); thus, the Th1 profile was identifiable only by a nonexpression of IL-4 or IL-10 in this area of endemicity.
3043 11509644 This was associated with a T2 shift in spleen, expansion of IL-4-producing and, to a lesser extent, of IFN-gamma-secreting T cells in pancreatic lymph nodes, as well as intermolecular Th2 epitope spreading to glutamic acid decarboxylase determinants.
3044 11509946 To provide a means for comparing strategies for cytokine gene therapy against intracranial (i.c.) tumors, we generated rat gliosarcoma 9L cells transfected with interleukin-4 (9L-IL4), interleukin-12 (9L-IL12), granulocyte-macrophage colony-stimulating factor (9L-GMCSF) or interferon-alpha (9L-IFNalpha).
3045 11514719 Co-expression of IL-4 increased vaccinia virus vector titres, while IFN-gamma co-expression reduced vaccinia virus replication in BALB/c mice and in C57BL/6 mice infected with some recombinant viruses.
3046 11535317 The CCR7 ligands, secondary lymphoid tissue chemokine (SLC) and Epstein-Barr virus-induced molecule 1 ligand chemokine (ELC), were recently recognized as key molecules in establishing functional microenvironments for the initiation of immune responses in secondary lymphoid tissue.
3047 11535317 Systemic co-transfer of both CCR7 ligands enhanced serum gB-specific IgG Ab but failed to elicit enhancement of distal mucosal IgA responses.
3048 11535317 CCR7 ligands also enhanced T cell-mediated immunity as measured by CD4+ T helper cell proliferation and CD8+ T cell-mediated CTL activity.
3049 11535317 Of particular interest, is the observation that SLC significantly increased the production of Th1-type cytokines (IL-2 and IFN-gamma) (P<0.05), whereas ELC increased the production of both Th1-type and Th2-type (IL-4) cytokines (P<0.05).
3050 11535318 Production of interferon-gamma, but not IL-4, was observed in response to DV stimulation.

3058 11552998 The number of DC obtained with 2% HSA-supplemented cultures containing granulocyte-macrophage colony-stimulating factor and interleukin 4 were consistently higher than in cultures with various concentrations of autologous plasma or serum.
3059 11555409 To evaluate the type of immunological response, mRNA transcription level for interleukin (IL)-4, IL-10, IL-12 and interferon (IFN)-gamma were determined using semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) technique in PBMCs of these volunteers.
3060 11555409 The results clearly demonstrated a high level of IL-4 expression in nonhealing cases of CL and a low expression level of transcripts for IFN-gamma and IL-12.
3061 11555409 In contrast, a high level of IFN-gamma and IL-12 expression and a low level of IL-4 and IL-10 expression were detected in the healing cases.

3069 11561730 Especially, the co-administration of IL-4, or the GM-CSF gene with the RSV-F gene construct, enhanced the production of anti-RSV-F Ab.
3070 11562066 Specifically, we examined the effect of mycobacterial antigens, Bacillus Calmette-Guerin (BCG) vaccine and Mycobacterium vaccae, on antigen-induced bronchoconstriction, airway hyperresponsiveness to methacholine, bronchoalveolar lavage eosinophilia, and plasma IL-4 and IL-12 levels in ovalbumin (OVA)-sensitized and challenged Balb/c mice.
3071 11564796 Th-modified IL-5 DNA vaccination reduces the expression of IL-5 and IL-4 by approximately 50% in the airways of allergen-challenged mice.
3072 11571536 Once tumors were established, the surgical site tumor was debulked and vaccination of syngeneic tumor transfectants encoding genes for IL-4, IL-2, GM-CSF, B7-1 or allogeneic MHC molecules commenced at a site away from both tumors, and tumor growth was measured.
3073 11580228 A chimeric construct of an MHC class II binding peptide from the c-erb oncogene (Her-2/neu) containing the N-terminal flanking region of CLIP elicited potent antitumor activity against a Her-2/neu-positive tumor in a rat model system.
3074 11580228 The induction of effective antitumor immunity, however, required presentation of the chimeric peptide construct on irradiated tumor cells or the peptide construct in concert with a Her-2/neu MHC class I-restricted peptide from Her-2/neu.
3075 11580228 Additionally, in vitro analysis revealed that immunization with the parent peptide resulted in a weak immune response to the unmodified peptide consisting of both type 1 (IL-2, IFN-gamma) and type 2 (IL-4, IL-10) cytokine-producing cells analyzed by RT-PCR (qualitative and quantitative) and by limiting dilution assay.
3076 11587806 Formalin-treated RSV vaccination has been linked specifically to the induction of Th2 cells, which make IL-4 and IL-5 and induce a strong pulmonary eosinophilic response.
3077 11591779 The major T cell population in the lungs of naive mice was CD4(+), and these cells were shown to be predominantly of Th2 type as in vitro polyclonal stimulation resulted in IL-4, but not IFN-gamma, production.
3078 11591779 After nasal immunization with influenza Ag alone, Th2 cytokine mRNA (IL-4 and IL-5) levels were increased, whereas there was no change in Th1 cytokine (IL-2 and IFN-gamma) mRNA expression.
3079 11591779 Coincidentally, both macrophage-inflammatory protein-1alpha (MIP-1alpha) and MIP-1beta mRNA expression increased in the lungs after immunization with Ag plus CT, while only MIP-1beta expression increased when mice were given influenza Ag alone.
3080 11591779 The major T cell population in the lungs of naive mice was CD4(+), and these cells were shown to be predominantly of Th2 type as in vitro polyclonal stimulation resulted in IL-4, but not IFN-gamma, production.

3108 11672898 We also tested the adjuvant activity of IL-12 and IL-4 on humoral responses to Sm23.
3109 11672898 Co-administration of plasmids encoding either IL-12 or IL-4 did not significantly enhance this protective effect.

3112 11672912 Many bulk T cell lines induced IFN-gamma, IL-5, but not IL-4.
3113 11672912 Thus, it appears that T cell response to MMP II is restricted by the HLA-DRB1 molecule, but not by DQ and DP molecules, which results in the induction of IFN-gamma production.
3114 11678901 The IL-4 was produced mainly by CD4+ cells, in contrast to IFN-gamma which was produced equally by CD4+, CD8+ and TCR-gammadelta+ cells.

3132 11691814 When combined with interleukin 4 (IL-4; 1000 units/ml), FP (0.34 microg/ml) induces differentiation of monocytes (CD14+) into dendritic cells (DCs) expressing surface markers characteristic for antigen-presenting cells.
3133 11691814 Up-regulation of mature DCs (CD83+CD19-; 17% versus 6%) with enhanced expression of HLA class I and class II antigens was detected in FP-cultured DCs as compared with DCs cultured with recombinant GM-CSF.
3134 11691814 Treatment of peripheral blood mononuclear cells (PBMCs) with FP alone (2.7 microg/10(7) cells) augments both T-cell helper 1 (Th1) and Th2 cytokine mRNA expression (IL-2, IL-4, GM-CSF, IFN-gamma, and tumor necrosis factor-alpha).
3135 11691814 Comparison of various immune manipulation strategies in parallel, bulk PBMCs treated with FP (0.34 microg/ml) plus IL-4 (1000 units/ml) for 1 week and restimulated weekly with FP plus IL-2 (20 IU/ml) induced maximal growth expansion of active T cells expressing the T-cell receptor and specific anti-RCC cytotoxicity, which could be blocked by the addition of anti-HLA class I, anti-CD3, or anti-CD8 antibodies.
3136 11691814 These results suggest that GM-CSF-G250 FP is a potent immunostimulant with the capacity for activating immunomodulatory DCs and inducing a T-helper cell-supported, G250-targeted, and CD8+-mediated antitumor response.

3149 11696194 A reduction of SEA-driven lymphoproliferation and of interferon (IFN)-gamma, interleukin (IL)-4 and IL-5 production, together with an increase in transforming growth factor (TGF)-beta1 production, were observed in splenic cells from CTB-Sm-p40-treated SEA-sensitized mice, as well as in liver leukocytes from CTB-Sm-p40-treated schistosome-infected mice.
3150 11696586 Combined allogeneic tumor cell vaccination and systemic interleukin 12 prevents mammary carcinogenesis in HER-2/neu transgenic mice.
3151 11696586 A significant improvement in tumor prevention was sought by administering allogeneic mammary carcinoma cells expressing HER-2/neu combined with systemic IL-12.
3152 11696586 The mammary glands of mice receiving the combined treatment displayed a markedly reduced epithelial cell proliferation, angiogenesis, and HER-2/neu expression, while the few hyperplastic foci were heavily infiltrated by granulocytes, macrophages, and CD8(+) lymphocytes.
3153 11696586 Specific anti-HER-2/neu antibodies were produced and a nonpolarized activation of CD4(+) and CD8(+) cells secreting IL-4 and interferon (IFN)-gamma were evident.
3154 11696586 A central role for IFN-gamma in the preventive effect was proven by the lack of efficacy of vaccination in IFN-gamma gene knockout HER-2/neu transgenic Balb/c mice.
3155 11696586 A possible requirement for IFN-gamma is related to its effect on antibody production, in particular on IgG2a and IgG2b subclasses, that were not induced in IFN-gamma knockout HER-2/neu mice.
3156 11696586 In conclusion, our data show that an allogeneic HER-2/neu-expressing cell vaccine combined with IL-12 systemic treatment can prevent the onset of genetically determined tumors.
3157 11703320 We have analysed the functional capability of DC generated in vitro from blood CD14(+) cells of chronic lymphocytic leukaemia (CLL) patients and healthy donors by culturing for 10 d with granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 4 (IL-4) and tumour necrosis factor-alpha (TNF-alpha).
3158 11703320 Most of the DC generated from both patients and controls exhibited a mature phenotype indicated by CD83 and major histocompatibility complex (MHC) class II expression, as well as by a characteristic morphology.
3159 11703320 CLL DC had a similar expression of accessory molecules (CD54, CD80 and CD86) as control DC.
3160 11703320 The mean fluorescence intensity of CD80 and MHC class I molecules was significantly higher on CLL DC than on control DC (P < 0.05).
3161 11703320 The expression of IL-4 and TNF-alpha was similar to that of control DC.
3162 11703320 We have analysed the functional capability of DC generated in vitro from blood CD14(+) cells of chronic lymphocytic leukaemia (CLL) patients and healthy donors by culturing for 10 d with granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 4 (IL-4) and tumour necrosis factor-alpha (TNF-alpha).
3163 11703320 Most of the DC generated from both patients and controls exhibited a mature phenotype indicated by CD83 and major histocompatibility complex (MHC) class II expression, as well as by a characteristic morphology.
3164 11703320 CLL DC had a similar expression of accessory molecules (CD54, CD80 and CD86) as control DC.
3165 11703320 The mean fluorescence intensity of CD80 and MHC class I molecules was significantly higher on CLL DC than on control DC (P < 0.05).
3166 11703320 The expression of IL-4 and TNF-alpha was similar to that of control DC.
3167 11709285 However, the inhibition is not alleviated by blocking with antibodies to IL-4, IL-10 or TGF-beta.
3168 11709285 Fractionation of the splenocyte population from S. mansoni-infected mice shows that the suppression is mediated by a non-B, non-T cell that expresses CD16 and Mac-1, but not FcepsilonR or NK1.1.
3169 11711604 Granulocyte-macrophage colony-stimulating factor expressed by recombinant respiratory syncytial virus attenuates viral replication and increases the level of pulmonary antigen-presenting cells.
3170 11711604 To investigate methods to augment the immune response, recombinant RSV (rRSV) was constructed that expresses murine granulocyte-macrophage colony-stimulating factor (mGM-CSF) from a transcription cassette inserted into the G-F intergenic region.
3171 11711604 Mice infected with rRSV/mGM-CSF had elevated levels of pulmonary mRNA for gamma interferon (IFN-gamma) and interleukin 12 (IL-12) p40 compared to animals infected by wild-type rRSV.
3172 11711604 The accumulation of total pulmonary mononuclear cells and total CD4(+) T lymphocytes was accelerated in animals infected with rRSV/mGM-CSF compared to that in animals infected with the control virus, and the level of IFN-gamma-positive or IL-4-positive pulmonary CD4(+) cells was elevated approximately twofold.
3173 11716105 By use of flow cytometry for the intracellular detection of cytokines an overall expansion of CD4+ and CD8+ T cells producing the Type 1 cytokines interleukin (IL)-2 and interferon (IFN)-gamma was observed in adults when compared with children, giving credit to the cumulative effect of contacts with environmental antigens.
3174 11716105 The CD4+ cells expressing the Type 2 cytokines IL-4 and IL-13, however, increased only in Africans, probably reflecting continuously present challenges with antigens that preferentially drive Type 2 responses.
3175 11726219 Generation of CD4(+) and CD8(+) T lymphocyte responses by dendritic cells armed with PSA/anti-PSA (antigen/antibody) complexes.
3176 11726219 We compared the capacity of DC to generate CD4(+) and CD8(+) T cell responses after exposure to prostate-specific antigen (PSA) alone, PSA targeted to the mannose receptor (mannosylated PSA (PSA-m)), or PSA targeted to Fc receptors by combining PSA with an anti-PSA antibody (AR47.47).
3177 11726219 Autologous CD3(+) T cells were added to monocyte-derived immature DC that had been cultured with GM-CSF/IL-4 for 4 days, exposed to antigen, and matured with CD40L or TNFalpha/IFN-alpha.
3178 11726219 Both CD4(+) and CD8(+) T cell responses were observed after stimulation with DC exposed to the PSA/anti-PSA complexes, whereas CD4(+) predominated over CD8(+) T cell responses after stimulation with PSA-armed DC or PSA-m.
3179 11726219 These CD8(+) T cells responded when rechallenged with DC pulsed with HLA allele-restricted PSA peptides.
3180 11731436 The vaccine used immature DC (CD14-, CD80+, CD86+, CD83-, and HLA-DR+) generated from peripheral blood monocytes in the presence of granulocyte/monocyte colony-stimulating factor and interleukin-4.
3181 11738755 The cytokine profile produced by splenocytes showed a high level of IL-4 in the inactivated virus group, high levels of IFN-gamma and IL-12 in the DNA vaccine group, and high levels of IL-10 and IFN-gamma in the VP1 protein group.
3182 11739538 These responses were associated with Ag-specific IFN-gamma and/or TNF-alpha secretion, but not IL-4, consistent with induction of Th1 immunity.
3183 11739872 Assessment of immune function by mitogen T cell proliferation, mitogen-induced interferon-gamma and interleukin-4 levels, IgG antibody responses and natural killer cell activity were not significantly different in mild to moderately biotin-deficient rats compared with biotin-sufficient controls.
3184 11745358 We found that, mainly CD8 T cells produced high levels of IL-13, while producing low levels of IL-4, IL-10 and IFN-gamma, upon primary and secondary stimulation.
3185 11754351 Lower expression levels in beta-cells support immune regulation resulting in induction of autoreactive, regulatory cells characterized by increased IL-4 production (Th2-like), whereas higher levels favor Th1-like autoaggressive responses characterized by augmented IFN-gamma generation.
3186 11756976 In vivo production of IL-12 was decreased during the viremic phase of the illness, and production of IL-4 was increased during and after atypical measles, compared with measles.
3187 11759072 Dendritic cells were derived from bone marrow and cultured in granulocyte-macrophage colony-stimulating factor/interleukin 4 before pulsation with tumor lysate.
3188 11759072 Multiple subcutaneous administrations of tumor lysate-pulsed dendritic cells (TP-DCs) resulted in an approximately eightfold hypertrophy of the vaccine draining nodes, with an increased influx of dendritic (CD11c+/CD80+) cells and B (B220+) cells.
3189 11759072 The vaccine-primed lymph node (VPLN) cells were secondarily activated with anti-CD3/interleukin 2 and exhibited specific interferon-gamma release to tumor antigen.
3190 11764291 A high level of HIV-1-specific cytotoxic T lymphocyte response was also observed, and a high level of IFN-gamma and IL-4 production was induced by the improved skin application of DNA vaccine.
3191 11764291 High levels of both HIV-specific cytotoxic T lymphocyte and delayed type hypersensitivity in topical application were induced by coadministration of the DNA vaccine with IL-12 expression plasmids and granulocyte-macrophage colony-stimulating factor expression plasmids.
3192 11803084 These responses were characterized by production of IFN-gamma, IL-2 and anti-MAP1 antibodies of predominantly IgG2a isotype, and were critical for protection against C. ruminantium infection.
3193 11803084 In addition, DBA/2 mice immunized with the recombinant MAP1 protein without DNA vaccine priming produced non-protective T(H2) type immune responses which were characterized by production of IL-4, IL-5, IL-10 and IgG1 anti-MAP1 antibodies.
3194 11803949 Gene gun immunisation induced a ThO type of immune response in mice characterised by a high IgG1/IgG2a ratio, and IL-4 and interferon (IFN)-gamma production.
3195 11826917 Interleukin-12 and interleukin-18 are macrophage products that favor the development of Th1 type of protective immune response.
3196 11826917 The production of anti-inflammatory cytokines such as IL-10, TGF-beta and IL-4 in response to M. tuberculosis may down regulate the immune response and limit tissue injury by inhibiting excessive inflammatory response.
3197 11836673 Systems studied have included lysis by interleukin-2 (IL-2)-activated lymphokine-activated killer (LAK) cells, tumor necrosis factor-alpha (TNF-alpha), a p16-expressing adenovirus vector, suicide gene therapy using the herpes simplex virus-tyrosine kinase (HSV-tk) followed by ganciclovir, and immunomodulatory gene therapy with IL-2, IL-4, interferon-gamma (IFN-gamma), IFN-alpha, TNF-alpha, granulocyte-macrophage colony-stimulating factor (GM-CSF), IL-6, and IL-1beta transfected into tumors.
3198 11836673 Since platelet-derived growth factor (PDGF) is thought to be an autocrine growth factor for mesothelioma STI-571 (Gleevec; Novartis, Basel, Switzerland), a highly selective inhibitor of the PDGF receptor tyrosine kinase, is being tested in a phase II trial.
3199 11840267 Leukaemia cells derived from 42 patients with AML were cultured in vitro with cytokines GM-CSF, IL-4 and TNFalpha/CD40L.
3200 11845255 Vaccination of stage IV patients with allogeneic IL-4- or IL-2-gene-transduced melanoma cells generates functional antibodies against vaccinating and autologous melanoma cells.
3201 11845255 The antibody (Ab) response to allogeneic Me14932 and autologous melanoma cells was analyzed in 13 Stage IV (AJCC) melanoma patients immunized with Me14932 cells transduced with the IL-4 (Me14932/IL-4) ( n=10) or IL-2 (Me14932/IL-2) ( n=3) gene.

3216 11854228 In this phase I trial of MSP-1(19), immunization of nonexposed human volunteers with either of the two allelic forms of recombinant MSP-1(19) induced high levels of antigen-specific Th1 (gamma interferon) and Th2 (interleukin 4 [IL-4] and IL-10) type lymphokines.
3217 11857339 Cellular and molecular requirements for the recall of IL-4-producing memory CD4(+)CD45RO(+)CD27(-) T cells during protection induced by attenuated Plasmodium falciparum sporozoites.
3218 11857339 We have previously demonstrated a recall of IL-4-producing memory CD4(+)CD45RO(+) T cells with parasitized red blood cells (pRBC) in persons protected by radiation-attenuated Plasmodium falciparum sporozoites (gamma-spz).
3219 11857339 Using the CD27 marker, we have now identified two subsets of CD4(+)CD45RO(+) T cells: CD4(+)CD45RO(+)CD27(+) T cells representing an early memory and CD4(+)CD45RO(+)CD27() T cells representing a terminally differentiated memory cells.
3220 11857339 A small subset of CD4(+)CD45RO(+)CD27(-) T cells also expressed CD70, the CD27 ligand.
3221 11857339 The addition of anti-CD70 monoclonal antibody (mAb) to pRBC-stimulated cultures significantly inhibited the conversion of CD27(+) to CD27(-) subset without profoundly affecting IL-4 production.
3222 11857339 In contrast, the inclusion of anti-CD27 mAb in parallel cultures abrogated IL-4 production without interfering with conscription of T cells into the CD27(-) T cell set.
3223 11857339 We propose that the persistence of memory CD4(+) T cells depends on Ag-driven conscription of a mature memory phenotype through co-ligation of CD27 and CD70 expressed, respectively, on CD27(+) and CD27(-) T cells.
3224 11857339 Hence, protracted protection in malaria depends in part on memory CD4(+) T cells that require specific Ag presumably from the repositories of liver-and blood-stage antigens and the delivery of a second signal from the CD27:CD70 interaction.

3247 11857339 We propose that the persistence of memory CD4(+) T cells depends on Ag-driven conscription of a mature memory phenotype through co-ligation of CD27 and CD70 expressed, respectively, on CD27(+) and CD27(-) T cells.
3248 11857339 Hence, protracted protection in malaria depends in part on memory CD4(+) T cells that require specific Ag presumably from the repositories of liver-and blood-stage antigens and the delivery of a second signal from the CD27:CD70 interaction.
3249 11858876 A study was conducted to evaluate the immunogenicity of the Brucella melitensis ribosome recycling factor (RRF)-homologous protein (CP24).
3250 11858876 Spleen cells from pcDNACP24-immunised mice did not produce interleukin (IL)-4, IL-10 or up-regulation of IL-2 mRNA.
3251 11858876 Cells from rCP24-immunised mice produced IL-10, up-regulated IL-2 mRNA but did not produce IL-4.
3252 11858876 However, the potential of CP24 for a Brucella diagnostic test based on an in vitro antigen (Ag)-specific IFN-gamma production or DTH test would be worth testing.

3257 11860706 Cytotoxic T lymphocyte antigen 4 (CTLA-4 or CD152) is a strong negative regulator of T cell activity.
3258 11860706 Like CD28 (a positive regulator) it binds to B7-1 and B7-2, and there is no known natural selective ligand.
3259 11860706 However, a single amino acid substitution in B7-1 (W88 > A; denoted B7-1wa) abrogates binding to CD28 but not to CTLA-4.
3260 11860706 Interferon-gamma and interleukin-4 were both depressed, arguing against a Th2 bias.
3261 11867164 We have examined T cell responses against recombinant analogues of the surface-exposed C. ruminantium major antigen 1 (MAP1) a 28.8 kDa protein and MAP2 (21 kDa) antigen in cattle immunised by infection and treatment.
3262 11867164 MAP1-specific responses were predominantly restricted to cluster of differentiation four antigen positive T cells (CD4+ T cells).
3263 11867164 Reverse transcription polymerase chain reaction (RT-PCR) analysis of cytokine expression by T cell lines derived from this population revealed strong expression of interferon gamma (IFN-gamma), interferon alpha (IFN-alpha), tumour necrosis factor alpha (TNF-alpha), tumour necrosis factor beta (TNF-beta), interleukin-2 receptor alpha (IL-2Ralpha) transcripts, and weak expression of IL-2 and IL-4.
3264 11867164 CD4+ T cell clones specific for MAP1 were generated.
3265 11867164 RT-PCR analysis of cytokine expression by T cell lines which were dominated by gammadelta T cells revealed expression of IFN-gamma, TNF-alpha, TNF-beta, IL-2Ralpha transcripts.
3266 11867164 Our findings indicate that immunisation of cattle by infection with C. ruminantium results in generation of MAP1- and MAP2-specific T cell responses that may play a role in protection against the pathogen.
3267 11872096 Furthermore, the bias towards Th2-type of responses stimulated by CT was shifted towards Th1 as demonstrated (i) by the increase of interferon-gamma and decrease of IL-4 cytokine levels measured in culture supernatants, (ii) by the predominance of IG2a anti-CT antibodies in the serum, and (iii) by the down-regulation of total serum IgE antibody levels.
3268 11874860 Lymphocyte proliferative responses, phenotypic characterization of CD4(+) and CD8(+) Leishmania-reactive T cells, and cytokine production were assayed.
3269 11874860 Patients with active ML and CL showed higher proportions of CD4(+) than CD8(+) T cells.
3270 11874860 In CL, the healing process was associated with a decrease of CD4(+) and an increase of CD8(+), leading to similar CD4(+) and CD8(+) proportions.
3271 11874860 Long-term follow-up of patients with CL showed a positive CD4(+)/CD8(+) ratio as observed during the active disease, although the percentages of these T cell subsets were significantly lower.
3272 11874860 Patients with CL did not show significant differences between gamma interferon (IFN-gamma) and interleukin-5 (IL-5) production during the period of study.
3273 11874860 Patients with active ML presented higher IFN-gamma and IL-5 levels compared to patients with active CL.
3274 11874860 Patients long term after cure from ML showed increasing production of IFN-gamma, significant decrease of IL-5, and no IL-4 production.
3275 11874860 Two apparently beneficial immunological parameters were detected in tegumentary leishmaniasis: (i) decreasing proportions of CD4(+) Leishmania-reactive T cells in the absence of IL-4 production associated with cure of CL and ML and (ii) decreasing levels of IL-5 long after cure, better detected in patients with ML.

3284 11877289 We found HBenvAg-specific T lymphocytes producing interferon-gamma, interleukin-4, or both in the peripheral blood of XLA patients up to at least 24 months after completing the standard anti-HBV immunization protocol.
3285 11877289 By combining cell purification and enzyme-linked immunospot assay, we found that effector CD27- T cells, which promptly produced cytokines in response to antigen (Ag), and memory-resting CD27+ T cells, which required Ag restimulation to perform their functions, were maintained in both XLA patients and controls for up to 24 months after the last vaccination boost.
3286 11884461 Ingestion of yeasts activates DC for production of IL-12 and Th1 priming, while ingestion of hyphae induces IL-4 production and Th2 priming.
3287 11884461 It was found that DC, from either spleens or bone marrow, transfected with yeast, but not hyphal, RNA 1) express fungal mannoproteins on their surface; 2) undergo functional maturation, as revealed by the up-regulated expression of MHC class II Ags and costimulatory molecules; 3) produce IL-12 but no IL-4; 4) are capable of inducing Th1-dependent antifungal resistance when delivered s.c. in vivo in nontransplanted mice; and 5) provide protection against the fungus in allogeneic bone marrow-transplanted mice, by accelerating the functional recovery of Candida-specific IFN-gamma-producing CD4(+) donor lymphocytes.

3290 11884466 In this study we demonstrate a similar pattern of enhanced disease severity following primary RSV infection of IFN-nonresponsive STAT1(-/-) mice.
3291 11884466 Histologically, STAT1(-/-) animals had eosinophilic and neutrophilic pulmonary infiltrates not present in wild-type or IFN-gamma(-/-)-infected mice.
3292 11884466 In cytokine analyses of infected lung tissue, IFN-gamma was induced in both STAT1(-/-) and wild-type mice, with preferential IL-4, IL-5, and IL-13 induction only in the STAT1(-/-) animals.
3293 11884466 Eotaxin was detected in the lungs of both wild-type and STAT1(-/-) mice following infection, with a 1.7-fold increase over wild-type in the STAT1(-/-) mice.
3294 11884466 Using a peptide epitope newly identified in the RSV fusion protein, we were able to demonstrate that wild-type memory CD4(+) T cells stimulated by this peptide produce primarily IFN-gamma, while STAT1(-/-)CD4(+) cells produce primarily IL-13.
3295 11884466 These findings suggest that STAT1 activation by both type I (alphabeta) and type II (gamma) IFNs plays an important role in establishing a protective, Th1 Ag-specific immune response to RSV infection.
3296 11904731 DC were generated from peripheral mononuclear cells by co-cultivation with granulocyte/macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4).
3297 11904731 After the cells had been pulsed with tumor antigens and co-cultured with autologous lymphocytes, the production of interferon-gamma (IFN-gamma) and IL-12 was analyzed, and lymphocyte proliferative response and cytotoxicity against the target tumor cell line were assessed.

3299 11904734 The authors performed a clinical study of a vaccine using autologous dendritic cells (DCs) pulsed with CEA652 and adjuvant cytokines, natural human interferon alpha (nhuIFN-alpha), and natural human tumor necrosis factor alpha (nhuTNF-alpha), for the treatment of patients with CEA-expressing advanced metastatic malignancies.
3300 11904734 DCs were generated from plastic adherent monocytes of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (PBMCs) in the presence of granulocyte/macrophage colony-stimulating factor (GM-CSF) and interleukin 4 (IL-4).
3301 11906763 In contrast, sensitization with recombinant Der f 11 (rDf11) and alum induced Th2 responses characterized by IgE responses and spleen cell secretion of IL-4 and IL-5.
3302 11906763 The debate whether CD4+ or CD8+ T cells were the regulatory cells to inhibit IgE responses by DNA vaccination was also examined.
3303 11906763 Secondly, adoptive transfer of either CD4- or CD8-depleted spleen cells from pDf11-vaccinated mice suppressed IgE responses.
3304 11906763 Both CD4+ and CD8+ T cells are crucial for the immunomodulation of IgE responses by pDf11.
3305 11906778 Immunisation with the oxidised conjugate resulted in significant antigen specific proliferative responses, IL-2, IFN-gamma and IL-4 production when compared to unconjugated controls.

3330 11918691 As interferon-gamma (IFN-gamma)-secreting CD4(+), T helper 1 (Th1) lymphocytes promote CTL activity and help maintain memory CTL, identifying broadly recognized EIAV Th1 epitopes would contribute significantly to vaccine strategies seeking to promote strong CTL responses among horses with varying class I haplotypes.
3331 11918691 Gag peptide-responsive PBMC produced only IFN-gamma, indicating a Th1 response, while Pol 323-344-responsive PBMC produced IFN-gamma both with and without interleukin-4.
3332 11918691 Finally, CD4(+) T lymphocytes were required for proliferation responses, as shown by assays using CD4- versus CD8-depleted PBMC.

3345 11929777 The combination of recombinant granulocyte macrophage-colony-stimulating factor (rGM-CSF) and recombinant interleukin-4 (rIL-4) provides an important stimulus for generating DCs from murine bone marrow precursors in vitro.
3346 11929777 DCs were highly concentrated in the T-cell areas of white pulp after rGM-CSF/IL-4 administration, whereas they were diffusely distributed throughout white pulp, marginal zones, and red pulp in mice treated with rGM-CSF alone. rGM-CSF/rIL-4 also significantly increased the expression of major histocompatibility complex (MHC) class I and MHC class II on CD11c(+) cells and increased their capacity to take up antigens by macropinocytosis and receptor-mediated endocytosis.

3373 11947931 In this study we provide evidence that a prolonged increase in the plasma levels of IL-2, but not IL-1beta, IL-4, IL-10, IL-2R or TNF-alpha occured in patients affected by bladder cancer following effective BCG treatment.
3374 11953366 Also, splenocytes from the inoculated mice expressed interleukin 2 (IL-2), gamma interferon, and small amounts of IL-4 and IL-5, and more IL-10 cytokine in the presence of the homologous antigen.
3375 11953389 Antibodies to the encoded BLS included immunoglobulin G1 (IgG1) IgG2a, IgG2b, IgG3, and IgM isotypes.
3376 11953389 In addition, spleen cells from vaccinated animals produced interleukin-2 and gamma interferon but not IL-10 or IL-4 after in vitro stimulation with recombinant BLS (rBLS), suggesting the induction of a Th1 response.
3377 11964715 IL-10 initiates anergy in T cells by blocking tyrosine phosphorylation of CD28 and inhibiting the CD28 co-stimulatory signal.
3378 11964715 Restimulation in the presence of IL-2, IL-15 and possibly IL-12 leads to a T helper type 1 cytokine pattern (immunity:effective immunotherapy) and with IL-4 a T helper type 2 pattern (persistence of allergy:relapse).
3379 11983254 Protective T-helper responses were not skewed towards an IFN-gamma (Th1) or IL-4 (Th2) type response, but were balanced and characterised by the presence of a strong Ag-specific IL-2 response.
3380 11986232 Specific proliferation and secretion of interleukin 4 and interferon gamma by mouse spleen cells in response to the immunizing peptides were also demonstrated.
3381 12007887 Distinct T (CD4+, CD8+, gammadelta-TCR+) and B (CD21+, CD45R+) lymphocyte staining patterns were observed within and around follicles of the rectal mucosa.
3382 12007887 RT-PCR examination of the cytokines expressed in the rectal mucosal tissue revealed consistently high levels of TGFbeta and IL-8 mRNA, low levels of IL-2 mRNA and no detectable IL-4 mRNA.
3383 12010483 On the other hand, the levels of IgG3 were significantly increased by IL-4, but unchanged by IL-12.
3384 12010483 However, the protective effect of the vaccine was not affected by coadministering plasmids encoding either IL-12 or IL-4 using the microseeding technique.

3388 12012014 In this study, we constructed a recombinant BCG-MUC1-IL2, which expresses a high level of human MUC1 VNTR core protein and secretes functional interleukin 2 (IL2).
3389 12012014 The mucin-specific IFN-gamma was secreted only by the lymphocytes derived from animals immunized with BCG-MUC1-IL2, but not with BCG-vector or purified mucin protein for the vaccination.
3390 12012014 In contrast, in vitro secretion of IL4 by the immunized lymphocytes was only seen in the group of animals which received native MUC1 protein, but not BCG-MUC1-IL2 and BCG-vector.
3391 12034099 The immune response generated by the CVP constructs showed a marked TH1 bias, as determined by a predominantly IgG(2a) isotype peptide-specific antibody response and the release of IFN-gamma but not IL-4 or IL-5 from lymphocytes exposed to antigen in vitro.
3392 12043855 To investigate whether a preexisting T helper (T(H)) 2 type immune response could be suppressed by Calmette-Guérin Bacillus (BCG) immunization in atopic children with asthma, we determined interferon (IFN)-gamma, interleukin (IL)-2, IL-4, and IL-5 and total IgE level in the supernatant of peripheral blood mononuclear cells (PBMC) of six atopic and five nonatopic children in response to phytohemagglutinin A (PHA), purified protein derivate (PPD), and Dermatophagoides pteronyssinus II allergen (Der p II) both before and after BCG vaccination.
3393 12057610 To study whether SIV VLPs represent effective mucosal immunogens, we immunized groups of mice with VLPs alone or VLPs plus the mucosal adjuvant cholera toxin (CT) by the intranasal (i.n.) route.
3394 12057610 High levels of serum IgG antibody production were achieved in mice immunized intranasally with SIV VLPs, and the antibody response was found to be antigen dose-dependent.
3395 12057610 The IgG1 and IgG2a ratio indicates that immune responses induced by SIV VLPs are Th1 oriented.
3396 12057610 Moreover, increased numbers of MHC I-restricted peptide-specific IFN-gamma and IL-4 producing T cells were detected in both splenocytes and lymph nodes by intranasal immunization of SIV VLP plus CT.
3397 12060497 HER-2/neu peptides have recently been shown to induce a proliferative response by peripheral CD4(+) T cells in breast cancer patients.
3398 12060497 The levels of the cytokines interferon-gamma (IFN-gamma), interleukin-4 (IL-4), and IL-10 were determined at priming and at restimulation with HER-2/neu peptides using a cytokine-specific, double-sandwich, enzyme-linked immunosorbent assay (ELISA).
3399 12060497 A Th1-specific cytokine production pattern was maintained at priming and restimulation with HER-2/neu peptides and was amplified with IL-12 costimulation.
3400 12069532 A pronounced increase in the frequency of FAS+ CD8+ lymphocytes was observed following SIVmacJ5 infection only.
3401 12069532 A transient increase in lymphocytes positive for intracellular IFN-gamma and IL-4 was observed following primary infection with either virus.
3402 12074699 Immunization with the pIDKE2 also generated a positive cellular immune response against the core antigen, determined by interferon-gamma enzyme-linked immunospot (ELISPOT) assay, and induced detectable levels of interferon-gamma but not interleukin-4 in vaccinated mice.
3403 12077226 We propose a classification of human CD4(+)CD45RO(+) memory T cells into three new subsets based on cell surface expression levels of CD43.
3404 12077226 The first subset consists of cells whose CD43 expression is relatively high; this subset also contains the highest proportion of recall Ag-reactive precursors, and its constituent cells respond far more strongly than cells in either of the other subsets to immobilized CD3 Ab in addition to secreting substantially more IFN-gamma and IL-4.
3405 12079558 Using synthetic RNA standards, we quantified mRNAs of IL-2, IL-4, IL-6, IL-10, IL-12 p40, interferon gamma (IFN-gamma), tumor necrosis factor alpha (TNF-alpha), RANTES, macrophage inflammatory protein 1 alpha (MIP-1 alpha), and MIP-1 beta in unstimulated peripheral blood mononuclear cells (PBMCs) and lymph nodes from macaques chronically infected with SIV or SHIV.
3406 12079558 Viremic monkeys with decreased CD4(+) T cell counts (<500 cells/microl) had significantly higher IL-10 mRNA expression than uninfected controls, which parallels the findings in HIV-1-infected humans.
3407 12079558 In addition, MIP-1 alpha, MIP-1 beta, and RANTES mRNA expression increased in viremic monkeys with decreased CD4(+) T cell counts; gene expression was inversely correlated with CD4(+) T cell counts, but not viral load.
3408 12094019 Peripheral CD4(+) and CD8(+) T cell populations were significantly lower in tg than in Ntg, df, or Ndf mice.
3409 12094019 No significant differences were found in CD4(+):CD8(+) T cell ratios, interleukin (IL)-4 concentrations or interferon (IFN)-gamma levels between tg,Ntg, df, and Ndf mice.
3410 12094019 Thus, high endogenous GH levels inhibit specific Ab production and peripheral T cell populations but not peripheral B cell numbers, Th2 cell populations, or IL-4 or IFN-gamma production.
3411 12094019 Peripheral CD4(+) and CD8(+) T cell populations were significantly lower in tg than in Ntg, df, or Ndf mice.
3412 12094019 No significant differences were found in CD4(+):CD8(+) T cell ratios, interleukin (IL)-4 concentrations or interferon (IFN)-gamma levels between tg,Ntg, df, and Ndf mice.
3413 12094019 Thus, high endogenous GH levels inhibit specific Ab production and peripheral T cell populations but not peripheral B cell numbers, Th2 cell populations, or IL-4 or IFN-gamma production.
3414 12096033 In vitro DC can be generated from human CD34(+) bone marrow cells and CD14(+) peripheral blood monocytes after culture with different cytokine combinations.
3415 12096033 Leukemic cells could be induced in the presence of IL-4 and CD40L to exhibit a DC morphology with a phenotype of mature DC-like cells.
3416 12096033 In addition, they expressed chemokine receptor CCR7 and CD62L, and could drive T cells towards a T(h)1 response with secretion of IFN-gamma.
3417 12096039 In this study we have demonstrated that a recombinant BCG (rBCG) secreting biologically active IL-2 has the ability to induce a T(h)1 profile in both immunocompromised and in IL-4 transgenic (Tg) mice.
3418 12096039 In the IL-4 Tg model, mice vaccinated with rBCG again produced a strong T(h)1 immune response, exhibiting a high antigen-specific IFN-gamma:IL-4 ratio and a concomitantly high IgG2a:IgG1 ratio.
3419 12096039 In this study we have demonstrated that a recombinant BCG (rBCG) secreting biologically active IL-2 has the ability to induce a T(h)1 profile in both immunocompromised and in IL-4 transgenic (Tg) mice.
3420 12096039 In the IL-4 Tg model, mice vaccinated with rBCG again produced a strong T(h)1 immune response, exhibiting a high antigen-specific IFN-gamma:IL-4 ratio and a concomitantly high IgG2a:IgG1 ratio.
3421 12104046 Hamster enriched DCs were prepared from bone marrow (BM) by a culture for 7 days in the presence of mouse GM-CSF and mouse IL-4, and characterized by the expression of specific DC markers (DEC205, DC-SIGN) mRNA using in situ hybridization (ISH).
3422 12110485 The production of interleukin-4 in response to each of the antigens tested was detected but was lower than that of IFN-gamma.
3423 12111121 Molecular requirements for CD8-mediated rejection of a MUC1-expressing pancreatic carcinoma: implications for tumor vaccines.
3424 12111121 We confirmed that a CD8(+) effector cell was required to eliminate MUC1-expressing Panc02 tumors, and demonstrated that T cells expressing TCR-alpha/beta and co-stimulation through CD28 and CD40:CD40L interactions played critical roles during the initiation of the anti-Panc02.MUC1 immune response.
3425 12111121 TCR-alpha/beta(+) cells were required to eliminate Panc02.MUC1 tumors, while TCR-gamma/delta(+) cells played a suppressive non-MUC1-specific role in anti-Panc02 tumor immunity.
3426 12111121 Type 1 cytokine interferon-gamma (IFN-gamma), but not interleukin-12 (IL-12), was essential for eliminating MUC1-expressing tumors, while neither IL-4 nor IL-10 (type 2 cytokines) were required for tumor rejection.
3427 12111121 In vitro studies demonstrated that IFN-gamma upregulated MHC class I, but not MHC class II, on Panc02.MUC1 tumor cells.
3428 12111121 Surprisingly, both perforin and FasL played unique roles during the effector phase of immunity to Panc02.MUC1, while lymphotoxin-alpha, but not TNFR-1, was required for immunity against Panc02.MUC1 tumors.
3429 12114290 In vitro cellular and humoral immune responses were measured to detect functional abnormalities in antigen presenting cells (autologous mixed leukocyte reactions and expression of interleukin (IL)-1beta, IL-6, IL-10, and tumor necrosis factor-alpha); T cells (lymphocyte proliferation using the polyclonal T-cell activators phytohemagglutinin and Concanavalin A; primary immune responses in allogeneic mixed leukocyte reactions; secondary immune response using the recall antigens tetanus toxoid, Candida albicans, and anthrax vaccine; and soluble IL-2 receptor expression); type-1 T-helper cells (gamma interferon expression); type-2 T-helper cells (IL-4 and IL-10 expression); and B cells (polyclonal B-cell activator pokeweed mitogen-induced immunoglobulin production).
3430 12117936 Oral immunization of mice with a Salmonella vaccine expressing colonization factor antigen I (CFA/I) from enterotoxigenic Escherichia coli results in the rapid onset of interleukin-4 (IL-4) and IL-5 production, which explains the observed elevations in mucosal immunoglobulin A (IgA) and serum IgG1 antibodies.
3431 12117936 Upon measurement of proinflammatory cytokines, minimal to no tumor necrosis factor alpha (TNF-alpha), IL-1alpha, IL-1beta, or IL-6 was produced by Salmonella-CFA/I-infected RAW 264.7 or peritoneal macrophages, but production was greatly induced in Salmonella vector-infected macrophages.
3432 12117936 Only minute levels of IL-12 p70 were induced by Salmonella vector-infected macrophages, and none was induced by Salmonella-CFA/I-infected macrophages.
3433 12117936 The absence of IL-12 was not due to overt increases in production of either IL-12 p40 or IL-10.
3434 12117942 Animals were primed with a mixture of DNA plasmids encoding two preerythrocytic-stage proteins and two erythrocytic-stage proteins from P. knowlesi and combinations of the cytokines granulocyte-macrophage colony-stimulating factor, interleukin-4, and tumor necrosis factor alpha and were boosted with a mixture of four recombinant, attenuated vaccinia virus strains encoding the four P. knowlesi antigens.
3435 12118725 Mice were inoculated s.c. with APC, either bone marrow-derived dendritic cells differentiated in medium supplemented with GM-CSF and IL-4 (BMDC), or with established dendritic cell lines DC2.4 or JAWS II.
3436 12133976 The s.c. administration of M. vaccae 3 wk before the immunization significantly reduced Ag-induced airway hyperreactivity and the increase in the numbers of eosinophils observed in the bronchoalveolar lavage fluid, blood, and bone marrow, even though no detectable changes in either cytokine (IL-4, IL-13, IL-5, and IFN-gamma) or total IgE levels were observed.
3437 12134231 Both native PT (nPT) and genetically detoxified PT (dPT) efficiently promoted expression on DCs of CD80, CD86, human leukocyte antigen-DR, and CD83 markers, alloreactive antigen presentation, and cytokine production, primarily interferon (IFN)-gamma.
3438 12134231 Although they did not affect interleukin (IL)-10 production by lipopolysaccharide (LPS)-stimulated DCs, both nPT and dPT strongly synergized with LPS for IL-12 production.
3439 12134231 PTs plus LPS-stimulated DCs secreted soluble factors fostering IFN-gamma but not IL-4 and IL-5 production by naive T cells.
3440 12149420 Although BRSV did not appear to replicate in MoDC or to affect expression of major histocompatibility complex (MHC) class I, MHC class II, or CD80/86, a higher percentage of cells exposed to live virus appeared to undergo apoptosis/necrosis.
3441 12149420 Exposure of MoDC to live BRSV induced more interleukin (IL)-10 mRNA and markedly less IL-12p40 and IL-15 mRNA than did heat-inactivated virus.
3442 12149420 Stimulation of CD4(+) T cells induced similar levels of IL-2-and IL-4-like activity and interferon-gamma.
3443 12149420 These observations suggest that while IL-10, produced by MoDC as a result of exposure to live BRSV, may affect IL-12 and IL-15 synthesis by MoDC, it does not appear to affect the cytokine response of BRSV-specific memory CD4(+) T cells.
3444 12151317 No significant differences were found with respect to frequencies of IFNgamma- or interleukin-4-producing cells in the lung in both rat strains.
3445 12164822 Both forms of the schistosome enzyme induced significant proliferation of splenocytes recovered from vaccinated mice, and expression of interferon (IFN)-gamma, interleukin (IL)-4 and IL-10 mRNA in these cells was detected using reverse transcriptase-polymerase chain reaction.
3446 12164822 Secretion of IFN-gamma, IL-4 and IL-10 by splenocytes from vaccinated mice was confirmed and quantified using enzyme-linked immunosorbent assay.
3447 12164822 IFN-gamma was the most abundant cytokine produced, followed by IL-4 and IL-10 in rank order.
3448 12164822 Both forms of the schistosome enzyme induced significant proliferation of splenocytes recovered from vaccinated mice, and expression of interferon (IFN)-gamma, interleukin (IL)-4 and IL-10 mRNA in these cells was detected using reverse transcriptase-polymerase chain reaction.
3449 12164822 Secretion of IFN-gamma, IL-4 and IL-10 by splenocytes from vaccinated mice was confirmed and quantified using enzyme-linked immunosorbent assay.
3450 12164822 IFN-gamma was the most abundant cytokine produced, followed by IL-4 and IL-10 in rank order.
3451 12164822 Both forms of the schistosome enzyme induced significant proliferation of splenocytes recovered from vaccinated mice, and expression of interferon (IFN)-gamma, interleukin (IL)-4 and IL-10 mRNA in these cells was detected using reverse transcriptase-polymerase chain reaction.
3452 12164822 Secretion of IFN-gamma, IL-4 and IL-10 by splenocytes from vaccinated mice was confirmed and quantified using enzyme-linked immunosorbent assay.
3453 12164822 IFN-gamma was the most abundant cytokine produced, followed by IL-4 and IL-10 in rank order.
3454 12174744 Expression of interferon gamma and interleukin 4 (a preliminary study)].
3455 12180110 The frequencies of CD8+ and CD4+ T cells responsive to cytomegalovirus (CMV), varicella zoster virus (VZV), and tetanus in antigen-activated whole blood were determined by flow cytometric analysis of CD69, TNF alpha, IFN gamma and IL-4 expression.
3456 12180110 In spite of a continuously reduced CD4 to CD8 ratio after transplantation, recovery of CD4+ T cells usually occurred prior to CD8+ recovery and often to a higher level.
3457 12191517 Monocytes were enriched from apheresis products by adherence and then cultured in the presence of AB serum or autologous plasma and GM-CSF and IL-4 for 6 days.
3458 12193722 Multiple Chlamydia pneumoniae antigens prime CD8+ Tc1 responses that inhibit intracellular growth of this vacuolar pathogen.
3459 12193722 Eighteen H-2(b) binding peptides representing sequences from 12 Cpn Ags sensitized target cells for MHC class I-restricted lysis by CD8(+) CTL generated from the spleens and lungs of infected mice.
3460 12193722 Peptide-specific IFN-gamma-secreting CD8(+) T cells were present in local and systemic compartments after primary infection, and these cells expanded after pathogen re-exposure.
3461 12193722 CD8(+) T cell lines to the 18 Cpn epitope-bearing peptides were cytotoxic, displayed a memory phenotype, and secreted IFN-gamma and TNF-alpha, but not IL-4.
3462 12193722 Finally, Cpn peptide-specific CD8(+) CTL suppressed chlamydial growth in vitro by direct lysis of infected cells and by secretion of IFN-gamma and other soluble factors.
3463 12193724 Clearance of facultative intracellular pathogens such as Salmonella requires IFN-gamma from CD4 T cells.
3464 12193724 Even transient attenuation of Ag presentation early during infection specifically abrogates the IFN-gamma component of the resulting CD4 T cell response.
3465 12193724 Furthermore, macrophages from IL-4-null mice secrete high levels of both IL-12 and IL-18 in response to stimulation in vivo even with dead bacteria, but this does not lead to induction of IFN-gamma-secreting T cells in response to immunization with dead S. typhimurium.
3466 12193724 Early IL-4 is contributed by triggering of CD4 NK T cells by dead, but not live, bacteria.
3467 12193724 Thus, Ag presentation-related IL-12-independent events and IL-4-sensitive IL-12-dependent events play crucial complementary roles in the generation of the IFN-gamma-committed CD4 T cell component of the immune response in Salmonella infection.
3468 12193724 Clearance of facultative intracellular pathogens such as Salmonella requires IFN-gamma from CD4 T cells.
3469 12193724 Even transient attenuation of Ag presentation early during infection specifically abrogates the IFN-gamma component of the resulting CD4 T cell response.
3470 12193724 Furthermore, macrophages from IL-4-null mice secrete high levels of both IL-12 and IL-18 in response to stimulation in vivo even with dead bacteria, but this does not lead to induction of IFN-gamma-secreting T cells in response to immunization with dead S. typhimurium.
3471 12193724 Early IL-4 is contributed by triggering of CD4 NK T cells by dead, but not live, bacteria.
3472 12193724 Thus, Ag presentation-related IL-12-independent events and IL-4-sensitive IL-12-dependent events play crucial complementary roles in the generation of the IFN-gamma-committed CD4 T cell component of the immune response in Salmonella infection.

3475 12193724 Furthermore, macrophages from IL-4-null mice secrete high levels of both IL-12 and IL-18 in response to stimulation in vivo even with dead bacteria, but this does not lead to induction of IFN-gamma-secreting T cells in response to immunization with dead S. typhimurium.
3476 12193724 Early IL-4 is contributed by triggering of CD4 NK T cells by dead, but not live, bacteria.
3477 12193724 Thus, Ag presentation-related IL-12-independent events and IL-4-sensitive IL-12-dependent events play crucial complementary roles in the generation of the IFN-gamma-committed CD4 T cell component of the immune response in Salmonella infection.
3478 12193742 IFN-gamma-inducible protein 10 (IP-10) is a CXC chemokine that is thought to manifest a proinflammatory role because it stimulates the directional migration of activated T cells, particularly Th1 cells.
3479 12193742 Self-specific Ab to IP-10 developed in protected animals, as well as neutralizing Ab to IP-10 that we have generated in rabbits, could inhibit leukocyte migration, alter the in vivo and in vitro Th1/Th2 balance toward low IFN-gamma, low TNF-alpha, high IL-4-producing T cells, and adoptively transfer disease suppression.
3480 12193742 After all, we did not neutralize the activity of other chemokines that bind CXCR3 (i.e., macrophage-induced gene and IFN-inducible T cell alpha chemoattractant) and yet significantly blocked not only adjuvant-induced arthritis but also the in vivo competence to mount delayed-type hypersensitivity.
3481 12198661 Bacterial motif DNA as an adjuvant for the breakdown of immune self-tolerance to pyruvate dehydrogenase complex.
3482 12198661 We therefore studied the effects of CpG motif-containing oligodeoxynucleotides (ODN) on responses to pyruvate dehydrogenase complex (PDC, the autoantigen in PBC) in a murine model.
3483 12198661 Administration of CpG ODN to SJL/J mice at the time of sensitization with PDC resulted in a significant skewing of splenic T-cell response to self-PDC, with significant augmentation of the Th1 cytokine response (interleukin [IL] 2 and interferon [IFN] gamma) and reduction of the Th2 response (IL-4 and IL-10).
3484 12208610 Spleen cells from immunized mice, after exposure to recombinant MPT SOD (MPT rSOD), produced significant levels of IFNgamma, TNFalpha and IL-6.
3485 12208610 IFNgamma and TNFalpha production was increased by the addition of Ribi.
3486 12208610 In contrast, low levels of NO, IL-4 and IL-10 were secreted by spleen cells culture from immunized mice.
3487 12209640 Moreover, the mucosal route resulted in the preferential induction of IFN-gamma producing T cells and of IgG2a antibody production, as compared to the dominant IL-4 and IgG1 responses obtained by the s.c. route, thus bringing a distinct advantage in the field of many infectious diseases and allergy.
3488 12218149 Despite the induction of significant anti-viral CD8+-mediated cytotoxic T lymphocyte and IFN-gamma responses, initial neonatal priming led to a lower frequency of virus-specific T cells compared with adult priming.
3489 12218149 A nonspecific and transient CD4+-mediated IL-4 response was present in all groups after secondary challenge with Cas or medium, indicating that this rise in type 2 cytokine production was not unique to mice that had been primed as neonates.
3490 12220808 FCA augmented IL-4, IL-5 and IL-10 production suggesting a strong Th2 response, while IFN-gamma and IL-12 remained low; poly I:C enhanced IFN-gamma, IL-12 and TNF-alpha eliciting a Th1 response; poly A:U resulted in a IL-10, IL-5, IL-6 and IL-12 secretion; and LPS enhanced the IL-10, IL-6 and TNF-alpha production.
3491 12228286 We designed a series of genetic constructs in which coding sequences for PsaA were linked to sequences encoding either murine interleukin-2 (mIL-2), mIL-4, or two copies of an immunostimulatory nonapeptide derived from mIL-1beta.
3492 12228286 Mice immunized twice with PsaA-IL-2, or PsaA-IL-4 responded with PsaA-specific antibody production comparable in magnitude to that of mice primed with PsaA in CFA and boosted with PsaA in incomplete Freund's adjuvant (PsaA-Adj).
3493 12228286 Antibodies elicited by PsaA-Adj were predominantly of the immunoglobulin G1 (IgG1) subclass, while PsaA-IL-2 and PsaA-IL-4 elicited substantial amounts of IgG2a in addition to IgG1.
3494 12228286 We designed a series of genetic constructs in which coding sequences for PsaA were linked to sequences encoding either murine interleukin-2 (mIL-2), mIL-4, or two copies of an immunostimulatory nonapeptide derived from mIL-1beta.
3495 12228286 Mice immunized twice with PsaA-IL-2, or PsaA-IL-4 responded with PsaA-specific antibody production comparable in magnitude to that of mice primed with PsaA in CFA and boosted with PsaA in incomplete Freund's adjuvant (PsaA-Adj).
3496 12228286 Antibodies elicited by PsaA-Adj were predominantly of the immunoglobulin G1 (IgG1) subclass, while PsaA-IL-2 and PsaA-IL-4 elicited substantial amounts of IgG2a in addition to IgG1.
3497 12228286 We designed a series of genetic constructs in which coding sequences for PsaA were linked to sequences encoding either murine interleukin-2 (mIL-2), mIL-4, or two copies of an immunostimulatory nonapeptide derived from mIL-1beta.
3498 12228286 Mice immunized twice with PsaA-IL-2, or PsaA-IL-4 responded with PsaA-specific antibody production comparable in magnitude to that of mice primed with PsaA in CFA and boosted with PsaA in incomplete Freund's adjuvant (PsaA-Adj).
3499 12228286 Antibodies elicited by PsaA-Adj were predominantly of the immunoglobulin G1 (IgG1) subclass, while PsaA-IL-2 and PsaA-IL-4 elicited substantial amounts of IgG2a in addition to IgG1.
3500 12236413 The full length cDNA encoding SjCTPI and P35, P40 amplified from pUC19-SjCTPI and murine IL-12 by PCR were subcloned into an eukaryotic expression vector (pcDNA3.1).
3501 12236413 Forty-five female C57BL/6 mice were divided into three groups; each mouse of the control group was injected with 100 pg of pcDNA3.1 by i.m. route; the TPI group was injected with 100 microg of pcDNA3. 1-SjCTPI; the TPI+IL- 12 group was injected with 100 microg of pcDNA3.1-SjCTPI and 100 pg of mixture of pcDNA3.1-P35 and pcDNA3.1-P40.
3502 12236413 Culture of spleen cells showed the production of IL-2, IL-4, IL-10 and IFN-gamma with the stimulation of specific antigen before and after challenge.
3503 12236413 The obvious rising of IL-2 in TPI group and TPI+IL-12 group before and after challenge was seen.
3504 12236413 The anti-rTPI antibody detection with Western-blot showed that ten serum samples from the control group were negative; nine of ten serum samples from the TPI group were weakly positive, eight of ten from the TPI+IL-12 group were weakly positive.
3505 12236413 The worm and egg reduction rates of TPI group and TPI+IL- 12 group were 27.9% and 13.7%, 31.9% and 18.6% respectively in comparison with the pcDNA group. pcDNA3.1-TPI DNA vaccine could confer partial protection against a subsequent challenge of Schistosoma japonicum in C57BL/6 mice and might therefore be a potential DNA vaccine.
3506 12270727 Cruzipain-specific type 1 cytokine responses characterized by the production of IFN-gamma but not IL-4 were also detectable during murine infection.
3507 12270727 The induction of serum antibody, mucosal IgA, Th1 cytokine and CTL responses by cruzipain in mice supports the use of this parasite protein for further efforts in T. cruzi vaccine development.
3508 12297400 OVA-specific proliferative response as well as interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) secretion in lymph node cell cultures of immunised mice were studied.
3509 12297400 PGM treatment in addition to OVA resulted in an increase of lymph node cellularity, stimulation of OVA-specific IFN-gamma and IL-4 production as well as of OVA-specific proliferative response.
3510 12297400 OVA-specific proliferative response as well as interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) secretion in lymph node cell cultures of immunised mice were studied.
3511 12297400 PGM treatment in addition to OVA resulted in an increase of lymph node cellularity, stimulation of OVA-specific IFN-gamma and IL-4 production as well as of OVA-specific proliferative response.
3512 12357348 In particular, ex vivo culture of ALL cells with CD40 ligand, incubation of AML cells with granulocyte-macrophage colony-stimulating factor and interleukin-4 (GM-CSF/IL-4) and lentiviral transduction of ALL and AML cells for expression of immunomodulators (CD80 and GM-CSF) are current approaches under investigation for the development of autologous acute leukemia cell vaccines.
3513 12379697 These infants also had lower median percentages of lymphocytes spontaneously making interleukin-4 (IL-4) or tumor necrosis factor alpha (TNF-alpha) and lower ratios of T cells spontaneously making IL-4 to T cells making IL-6.
3514 12385032 In experiments designed to get insights into the interactions between PTX and circulating immune cells, we first observed that addition of PTX to adult whole blood induced the release of IL-12 and TNF-alpha as well as maturation of myeloid dendritic cells (DC).
3515 12385032 Secondly, studies on DC generated in vitro by culturing monocytes with IL-4 and GM-CSF showed that PTX directly stimulates MHC class II and costimulatory molecules up-regulation, cytokine synthesis and NF-kappa B activation.

3561 12399972 Our results demonstrate that leukemic DC generated in the presence of GM-CSF, IL-4 and matured with CD40L, are composed of two major subsets: DC derived from CD14(+) leukemic cells and leukemic DC derived from in vivo expanded circulating blood myeloid DC (MDC).
3562 12406650 For example, IFN-gamma has been linked to IgG2a and IgG3 production, IL-4 to IgG1 and IgE production and TGF-beta to IgA production.
3563 12406650 That is, IgG1 expression is positively regulated by IL-4 and IgG2 expression is positively regulated by IFN-gamma.
3564 12406650 For example, IFN-gamma has been linked to IgG2a and IgG3 production, IL-4 to IgG1 and IgE production and TGF-beta to IgA production.

3566 12406881 Local and systemic effects of an allogeneic tumor cell vaccine combining transgenic human lymphotactin with interleukin-2 in patients with advanced or refractory neuroblastoma.
3567 12406881 They received up to 8 subcutaneous injections of a vaccine combining lymphotactin (Lptn)- and interleukin-2 (IL-2)-secreting allogeneic neuroblastoma cells in a dose-escalating scheme.
3568 12406881 Injection-site biopsies revealed increased cellularity caused by infiltration of CD4+ and CD8+ lymphocytes, eosinophils, and Langerhans cells.
3569 12406881 Systemically, the vaccine produced a 2-fold (P =.035) expansion of CD4+ T cells, a 3.5-fold (P =.039) expansion of natural killer (NK) cells, a 2.1-fold (P =.014) expansion of eosinophils, and a 1.6-fold (P =.049) increase in serum IL-5.
3570 12406881 Supernatant collected from restimulated cells showed increased amounts of IL-4 (11.4-fold; P =.021) and IL-5 (8.7-fold; P =.002).
3571 12406881 Hence, allogeneic tumor cell vaccines combining transgenic Lptn with IL-2 appear to have little toxicity in humans and can induce an antitumor immune response.
3572 12415308 Established models of T-helper-2-cell dominance in BALB/c mice infected with Leishmania major -- involving the early production of interleukin-4 by a small subset of Leishmania-specific CD4+ T cells -- have been refined by accumulating evidence that this response is not sufficient and, under some circumstances, not required to promote susceptibility.
3573 12438346 Intranasal vaccinations were given with recombinant interleukin-12 (IL-12)- and IL-4-neutralizing antibody (Ab) for type 1 immune bias, or recombinant IL-4 and gamma interferon-neutralizing Ab for type 2 immune bias.
3574 12441072 Enhanced clearance of herpes simplex virus type 1 and reduced herpetic eye disease in STAT6 knockout mice is associated with increased IL-2.
3575 12441072 STAT6 (signal transducers and activators of transcription 6)-deficient (STAT6-/-) mice have defects in IL-4- and IL-13-mediated functions and thus have a reduced T(H)2-mediated immune response.
3576 12441072 Lymphocytes from both vaccinated and mock-vaccinated STAT6-/- mice secreted higher amounts of IL-2 than lymphocytes from BALB/c mice, in the presence or absence of stimulation with UV-inactivated HSV-1.
3577 12441072 Finally, depletion of IL-2 increased ocular virus replication in STAT6-/- mice to levels similar to that measured in BALB/c mice.
3578 12441072 Our results suggest that in the absence of the STAT6 pathway, IL-2-mediated immune responses are up-regulated.
3579 12444136 B7/CD28-dependent CD4+CD25+ regulatory T cells are essential components of the memory-protective immunity to Candida albicans.
3580 12444136 Here we show that CD4(+)CD25(+) T cells, negatively regulating antifungal Th1 reactivity, are generated in mice with candidiasis.
3581 12444136 CD4(+)CD25(+) T cells were not generated in B7-2- or CD28-deficient mice or in condition of IL-10 signaling deficiency.
3582 12444136 CD4(+)CD25(+) T cells poorly proliferated in vitro; were highly enriched for cells producing IL-4, IL-10, and TGF-beta; and required IL-10-producing, Candida hypha-activated dendritic cells for generation.
3583 12444136 Adoptive transfer of CD4(+)CD25(+) T cells or IL-10-producing dendritic cells restored resistance to reinfection and decreased inflammation in B7-2-deficient mice.
3584 12460198 Alum-bound rPhl p 5b induced a preferential allergen-specific Th2-response characterized by high immunoglobulin G1 (IgG1) antibody levels and elevated interleukin (IL)-4 and IL-5 production in cultured splenocytes.
3585 12460198 By contrast, CBP-bound rPhl p 5b, but not rPhl p 5b alone or coadministered with CBP, induced a mixed allergen-specific T helper 1 (Th1)/Th2 immune response characterized by the additional production of allergen-specific IgG2a/b antibody responses and elevated interferon-gamma production.
3586 12477285 By contrast, T helper 2 responses (IL-4 and IL 10 release) correlate with disease exacerbation and pathology.
3587 12496190 Clearance of parasites from the skin was correlated with an inflammatory response and the infiltration and activation of CD4(+) and CD8(+) T cells.
3588 12496190 In contrast, in lymphoid tissue (lymph node or spleen), the production of Th1/Th2 cytokines (interleukin-4 [IL-4], IL-10, and gamma interferon) appeared to correlate with parasite burden and pathogenesis.
3589 12496431 Previous studies have shown that nCT as mucosal adjuvant requires IL-4 and induces CD4-positive (CD4+) Th2-type responses, while nLT up-regulates Th1 cell production of IFN-gamma and IL-4-independent Th2-type responses.

3659 12512800 Forty to fifty percent of both samples, frozen/thawed as well as fresh BMDC, exhibited characteristic DC morphology, and the DC obtained from the frozen/thawed samples expressed a similar level of MHC class I-, MHC class II-, CD80-, CD86-, CD11c-, CD11b-, CD54- and CD205-molecule as fresh DC.
3660 12513792 The phenotype of DC was detected by FCM with CD1a, CD40, CD80, CD86, HLA-A, B, C and HLA-DR monoclonal antibodies.
3661 12513792 The level of IL-12 and IFN-gamma in supernatant of DC culture was measured by ELISA.
3662 12513792 A high expression of phenotypes was found in HL-60-DC and THP-1-DC stimulated by GM-CSF + IL-4 + TNF-gamma and K562-DC with GM-CSF + IL-4 + IL-12.
3663 12513913 Endogenous interleukin-4 downregulates the type 1 CD4 T cell-mediated immune response induced by intramuscular DNA immunization.
3664 12513913 IL-4-deficient mice had a significantly lower ratio of specific serum IgG1/IgG2a, and on in vitro restimulation with antigen, their spleen cells secreted significantly higher amounts of interferon-gamma (IFN-gamma).
3665 12513913 In contrast, absence of IL-4 did not affect total serum antibody response, T cell proliferative responses, or activation of IFN-gamma-producing CD8(+) T cells.
3666 12513913 To our knowledge, our study provides the first evidence that endogenous IL-4 selectively downregulates the type 1 CD4(+) T cell-mediated immune response induced by i.m. genetic immunization, a fact that may have implications for the design of certain DNA vaccines.

3679 12516566 Here, we studied the allergen-specific CD4+ and CD8+ T cell populations induced following immunization of allergic and non-allergic mice with DNA vaccine vectors encoding discrete epitopes of the house dust mite (HDM) Dermatophagoides pteronyssinus group I (Der p 1) allergen.
3680 12516566 Using Elispot analysis, we demonstrate that allergic/vaccinated mice generate a mixed Th1/Th2 response against the allergen with high numbers of allergen-specific CD4+ T cells secreting IFN-gamma or IL-4, whereas in non-allergic/vaccinated mice a polarized Th1 response was dominant.
3681 12516566 Allergen-specific CD8+ T cells secreting IFN-gamma were induced at equal frequencies in both allergic and non-allergic mice.
3682 12522051 Fifteen human cytokines (interleukin 1alpha [IL-1alpha], IL-1beta, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-15, IL-17, IL-18, gamma interferon, and tumor necrosis factor alpha) were validated with a panel of healthy individuals, rheumatoid arthritis patients, and juvenile idiopathic arthritis patients.
3683 12526058 Spleen cells from mice immunized nasally with the vaccine and toxin produced interleukin-2 (IL-2) at the same level on restimulation in vitro with glycoprotein H: glycoprotein L (gH:gL), gB, and gE:gI, but not IL-4.

3685 12526058 Immunization with gH:gL and the toxin showed increased thymidine uptake and production of IL-2 and interferon-gamma (IFN-gamma) of the spleen cells, but not IL-4, depending on the dose of gH:gL used for immunization and restimulation in vitro.

3692 12531338 Previous studies had demonstrated that enhanced clearance was linked to increased production of both Th1 and Th2 cytokines (IFN-gamma and IL-4, respectively) in regional lymph nodes, and increased secretion of IFN-gamma and NO in saliva.
3693 12531338 Compared to control mice, those given the oral vaccine had a 4 log reduction in colonisation on day 2, associated with twice the levels of secretion of IFN-gamma and IL-4 from the regional node cells, five times the level of nitric oxide in saliva, and suppression of NO production with MMLA induced a 2 log increase in oral colonisation.
3694 12531338 Thus while both IFN-gamma and IL-4 appear to contribute to clearance of oral C. albicans, IL-4 appears to act through a paracrine enhancement of NO production.

3701 12531363 Plasmids encoding mouse IL-4 and IL-18 under cytomegalovirus promoter were constructed and transformed into live attenuated Salmonella enterica serovar Typhi strain CVD 908-htrA, and Salmonella enterica serovar Typhimurium strain SL3261.
3702 12531644 Our data showed that i.n. route of immunization induced the most favorable stimulation of mucosal antigen-specific IgA responses supported by mixed Th cells producing IL-4, IL-5, IFN-gamma.
3703 12536236 The ability of acute myeloid leukaemia (AML) cells to acquire dendritic cell (DC)-like characteristics in vitro with a rapid culture method based either on the phorbol ester PMA or calcium ionophores has been studied in comparison to conventional AML-DC cultures with the cytokines granulocyte-macrophage colony-stimulating factor (GM-CSF), tumour necrosis factor-alpha (TNF-alpha), interleukin-3 (IL-3), SCF, FLT3-L and IL-4.
3704 12536236 The most mature APC were generated by calcium ionophore A23187 plus IL-4, as evidenced by the higher expression of CD40, CD80, CD86 and HLA-DR.

3707 12538699 Then, in the course of infection the initial IFN-gamma response to these two epitopes shifted to a mixed IFN-gamma/IL-4 response.
3708 12540559 We here report that BALB/c interleukin-4 knockout (IL-4(-/-)) mice are weakly overcolonized compared to the wt strain but that the IL-12(-/-) knockout results in a strong overcolonization (500%).
3709 12540559 The IL-4(-/-) mutation caused a 50% reduction and the IL-12(-/-) knockout caused a 95% reduction compared to the wt colonization rate.
3710 12540559 For C57BL/6J mice we further analyzed the IL-18(-/-) and Toll-like receptor 2 knockout mutations, which showed reductions to 66 and 57%, respectively, whereas mice with the IL-10(-/-) phenotype were hardly infected at all (5%).
3711 12540559 In contrast, the tumor necrosis factor receptor knockout (p55(-/-) and p55/75(-/-)) mice showed an overcolonization compared to the C57BL/6J wt strain.
3712 12540559 With exception of the low-level infected C57BL/6J IL-10(-/-) and IL-12(-/-) knockout mice, all knockout mutants were accessible to a prophylactic vaccination and their vaccination behavior was comparable to that of the wt strains.
3713 12540559 We here report that BALB/c interleukin-4 knockout (IL-4(-/-)) mice are weakly overcolonized compared to the wt strain but that the IL-12(-/-) knockout results in a strong overcolonization (500%).

3718 12540573 Vaccine-induced reduction of Helicobacter pylori colonization in mice is interleukin-12 dependent but gamma interferon and inducible nitric oxide synthase independent.
3719 12540573 Elevated levels of mRNA for interleukin-12p40 (IL-12p40), gamma interferon (IFN-gamma), tumor necrosis factor alpha, and inducible nitric oxide synthase (iNOS) were associated with protection in immunized-challenged (I/C) mice, but Th2 cytokine (IL-4, IL-5, IL-10, and IL-13) and chemokine (KC, MIP-2, and MCP-1) expression was not associated with protection.
3720 12540573 Despite the association of IFN-gamma and iNOS message with protection, I/C mice genetically lacking either of these products were able to reduce the bacterial load as well as the wild-type I/C controls.
3721 12540573 We conclude that neither IFN-gamma nor iNOS is essential for vaccine-induced protection from H. pylori infection.
3722 12540573 The p40 subunit of IL-12, which is a component of both IL-12 and IL-23, is necessary for protection in immunized mice.
3723 12547348 RT-PCR analyses of mRNAs in the skin of vaccinated animals indicated increased expression of interleukin (IL)-4 relative to gamma-interferon (gamma-IFN).
3724 12547597 The cells were cultured in a serum-free medium with different cytokine combinations including GM-CSF, TNF-alpha, Flt-3, CD40L, IFN-gamma, IL-1alpha, IL-6, PGE1, and IL-4.
3725 12547598 Immature human DC were generated from peripheral blood monocytes cultured with GM-CSF and IL-4.
3726 12547598 Uptake of antigen by DC and the degree of expression of the cell surface markers MHC class II, CD80, CD86 and the DC maturation marker CD83, was investigated by flow cytometry following incubation with liposomes or solution containing FITC-conjugated antigen.
3727 12560579 This allowed a semi-quantitative analysis of IFN-gamma, IL-2, IL-4, IL-10 and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene expression levels from porcine peripheral blood mononuclear cells (PBMCs).
3728 12560579 In addition, when PBMCs from pigs immunized previously with classical swine fever virus (CSFV) vaccine were cultivated with the recall antigen, CSFV, in the presence of PRRSV, significant upregulation of IL-10 gene expression and reduction of IFN-gamma gene expression were observed.
3729 12562379 IFN-gamma and TNF-alpha, the two major cytokines associated with DTH, were efficiently induced by BCG.
3730 12562379 Constitutive levels of IL4 and IL5 were observed, but neither IL4 nor IL5 were modulated by BCG.
3731 12562379 Production of Th1 (T helper type 1) cytokines (IFN-gamma, IL2 and IL12) preceded that of the Th2 (T helper type 2) cytokine IL10.
3732 12562379 A tendency toward higher ratios of IFN-gamma versus IL10 for BCG responders also was observed.
3733 12568121 Firstly, BALB/c mice were immunized with cDNAs for G2s and the TSHr, alone or in tandem with cDNAs for interleukin (IL)4 or IL12.
3734 12568121 Antibody levels in mice immunized with G2s + TSHr or G2s + IL12 were generally higher than those in mice immunized with G2s only.
3735 12568121 TRAb levels were greatest in mice immunized with both G2s and the TSHr in the presence of TL4, but not IL12.
3736 12568121 Overall, the greatest histological changes were observed in CD-1 mice immunized with both G2s + TSHr + IL4.
3737 12568121 These results indicate that we have established a valid model for human ophthalmopathy using the novel thyroid and eye muscle expressed protein G2s, now recognized as a fragment of the winged-helix transcription factor Foxp1, and TSHr, and that G2s and the TSHr are both primary antigens in TAO.

3753 12574338 Inoculation of CPB2.8 (< or =5 microg) into the footpads of BALB/c mice not only up-regulated mRNA transcripts for IL-4 and IL-4 production in the draining popliteal lymph nodes, but also polarized splenocyte anti-CD3 stimulated responses toward a Th2 bias as measured by increased IL-5 production compared with controls.
3754 12574338 Furthermore, enzymatically active (<0.1 U/ml) but not E-64-inactivated CPB2.8 was able to proteolytically cleave CD23 and CD25, although not B220 or CD4 from murine lymphocytes.
3755 12574345 We failed to detect any effects on ex vivo MOG-peptide-induced IFN-gamma, TNF-alpha, IL-6, IL-4, IL-10, and brain-derived neurotropic factor expression in splenocytes or CNS-derived lymphocytes.
3756 12574345 In CNS-derived lymphocytes, Fas ligand expression was down-regulated in DNA-vaccinated rats compared with controls.
3757 12574374 Although well studied in settings of helminth infection and allergen sensitization, the combined contributions of IL-4 and IL-13 and their signaling pathways in models of viral pathogenesis have not been reported.
3758 12574374 Using a murine model of respiratory syncytial virus (RSV) infection, we evaluated the contribution of IL-13, alone and in conjunction with IL-4, during immunization with recombinant vaccinia virus expressing RSV G glycoprotein (vvGs) or with formalin-inactivated RSV (FI-RSV).
3759 12574374 We showed that both IL-4 and IL-13 activity must be inhibited to modulate G-specific responses resulting in severe RSV-induced disease.
3760 12574374 Inhibition of IL-4 or IL-13 activity alone had minimal impact on disease in vvGs-immunized mice.
3761 12574374 However, treatment of IL-4-deficient mice with IL-13Ra during vvGs immunization reduced IL-5, IL-13, and eotaxin production and pulmonary eosinophilia after RSV challenge.
3762 12574374 In contrast, FI-RSV-induced immune responses were diminished when either IL-4 or IL-13 activity was blocked.
3763 12574374 Our data suggest that secreted vvGs uses mechanisms requiring signaling through the IL-4Ralpha-chain by either IL-4 or IL-13 for induction of eosinophilia and is the first description of the relative contributions of IL-4, IL-13, and their receptors in viral pathogenesis.

3787 12574374 We showed that both IL-4 and IL-13 activity must be inhibited to modulate G-specific responses resulting in severe RSV-induced disease.
3788 12574374 Inhibition of IL-4 or IL-13 activity alone had minimal impact on disease in vvGs-immunized mice.
3789 12574374 However, treatment of IL-4-deficient mice with IL-13Ra during vvGs immunization reduced IL-5, IL-13, and eotaxin production and pulmonary eosinophilia after RSV challenge.
3790 12574374 In contrast, FI-RSV-induced immune responses were diminished when either IL-4 or IL-13 activity was blocked.
3791 12574374 Our data suggest that secreted vvGs uses mechanisms requiring signaling through the IL-4Ralpha-chain by either IL-4 or IL-13 for induction of eosinophilia and is the first description of the relative contributions of IL-4, IL-13, and their receptors in viral pathogenesis.

3806 12586483 Differentiation of porcine dendritic cells by granulocyte-macrophage colony-stimulating factor expressed in Pichia pastoris.
3807 12586483 Strategies to enhance their function, such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-4 treatment to induce DC differentiation from peripheral blood monocytes, may therefore be useful as vaccine adjuvants.
3808 12589958 Real-time PCR confirmed the memory effect on T-cell subsets secreting interleukin-4 and interferon-gamma, as a consequence of stimulation of both arms of the immune system.
3809 12594331 We generated CD4(+) T cell lines to fractions of native antigens from the blood stages of the rodent parasite, Plasmodium yoelii, and identified fraction-specific T cells that had a Th1 phenotype (producing IL-2, IFN-gamma, and tumor necrosis factor-alpha, but not IL-4, after antigenic stimulation).
3810 12594570 The purpose of this work was to optimize the ex-vivo production of functional TAA-loaded DC that would produce interleukin-2 (IL-12) and enhance the T cell response.
3811 12594570 We generated ex-vivo DC from human monocytes with granulocyte macrophage-colony stimulating factor (GM-CSF) and IL-4, and whole necrotic tumor cells (cell lysates) of cancer cell lines were used as model TAA.
3812 12594570 TNF-alpha matured DC phenotypically, but additional interferon-gamma (IFN-gamma) treatment was necessary to achieve functional maturation, the production of significant amounts of IL-12.
3813 12594570 Our results suggest that after allowing 4 h of tumor lysate uptake by immature DC, further treatment with TNF-alpha and IFN-gamma for 24 h provides the optimal conditions to obtain functional TAA-loaded DC.
3814 12595418 The dynamics of gamma interferon (IFN-gamma)- and interleukin-4 (IL-4)-secreting CD4 T cells were analyzed after priming through intragastric delivery of an attenuated delta actA recombinant L. monocytogenes strain expressing the Leishmania major LACK protein; a peptide of this protein, LACK(158-173) peptide (pLACK), is a well-characterized CD4 T-cell target in BALB/c mice.
3815 12595418 Efficient priming of IFN-gamma-secreting pLACK-reactive CD4 T cells was observed in all tested compartments.

3820 12595427 The levels of interleukin-2 (IL-2), IL-4, and gamma interferon mRNAs in the immunized animals were elevated, and the proliferation of spleen cells was also enhanced in the immunized animals.
3821 12603608 A significant correlation (P < 0.025) between immunogenicity and the ratio of tumour-specific interferon-gamma : interleukin-4 (IL-4) secretion by TVDLN T cells was identified.
3822 12603608 We then documented that non-therapeutic T cells primed by the poorly immunogenic D5, recognized "tumour-rejection" antigens and that reprogramming their cytokine response, by in vitro culture with IL-12 and anti-IL-4, to a T1 profile uncovered therapeutic efficacy.

3825 12605698 The cells were stimulated in vitro with recombinant HBsAg and PHA mitogen and concentrations of IL-4, IL-10 and IFN-gamma were quantified in culture supernatants by sandwich ELISA.
3826 12605698 Our results demonstrated significantly increased production of all cytokines, including IL-4 (P < 0.001), IL-10 (P < 0.002) and IFN-gamma (P < 0.01) in responder compared to nonresponder vaccinees.

3829 12607723 CFSE-labeled PBMC were stimulated with a superantigen (SEB), a recall antigen (tetanus toxoid), an allergen (grass pollen) and an autoantigen (nucleosomes) and stained after cultivation with CD4-, CD8- and CD19-antibodies.
3830 12607723 Analyzing the cytokine secretion pattern of allergen-reactive proliferated Th cells after polyclonal restimulation we found differences in the expression of IL-13 and IL-4 between an atopic and a healthy donor.
3831 12607723 After stimulation of PBMC from TT-vaccinated donors TT-specific proliferated B cells were detected in high frequencies and showed a plasmablast-typical CD20(low) CD27(high) phenotype with only low frequencies expressing CD138 (= Syndecan-1).
3832 12610137 After intranasal coadministration with VLPs, RANTES or CpG ODN also induced increased levels of gamma interferon (IFN-gamma)-producing lymphocyte and cytotoxic T-lymphocyte activities in both spleen and lymph nodes but did not increase the levels of interleukin-4-producing lymphocytes.
3833 12611171 Priority data on the induction, by using a Russian live cold-adapted reassortant influenza vaccine (LIV), of the cellular and humoral immunity with regard for attenuation and genetic reassortment of vaccine stains as well as with regard for the age of vaccinated persons and the production of Th1 (IFNY, IL-2) and Th2 (IL-4) cytokine markers in vitro are presented.
3834 12611171 LIV was found to stimulate well enough the production of IFN and IL-2 in both young and old persons.
3835 12615427 This immunization resulted in a Th1-type response with predominance of IgG2a and a specific T-cell proliferation with high levels of interferon-gamma (IFN-gamma) secretion, whereas no IL-4 was detected.

3839 12616109 The authors hypothesized that systemic administration of granulocyte-macrophage colony-stimulating factor (GM-CSF) plus interleukin (IL)-4 might lead to the differentiation of DC from their precursors and enhance their number and function in vivo, as it does in vitro.

3874 12618487 In a previous study we showed that immunization with dendritic cells (DC) pulsed with idiotype (Id) fused with CD40 ligand (CD40L) could break the tolerance to Id which is expressed on B lymphoma cells and restored the responsiveness of T(h) cells, and, subsequently, induced IgG antibody response.
3875 12618487 On examining the mechanism for this isotype change, we found that IFN-gamma production by CD4(+) T cells is not the only determining factor for achieving a successful therapy.
3876 12618487 The deciding factor appears to be the abrogation of IL-4 production that was achieved by combing with IL-12 gene therapy.
3877 12626574 In vivo depletion of CD4(+) T lymphocytes could completely abrogate the antitumor activity, whereas the depletion of CD8(+) cells showed partial abrogation.
3878 12626574 The adoptive transfer of CD4-depleted (CD8(+)) or CD8-depleted (CD4(+)) T lymphocytes isolated from mice immunized with hEe-p vaccine showed the antitumor activity.
3879 12626574 In addition, the increase in level of both IFN-gamma and IL-4 was found.
3880 12639485 All groups demonstrated a heavy bias toward a Th1 immune response, as evidenced by high serum IgG2a/IgG1 ratios and the predominance of IFN-gamma over IL-4 secretion from cultured splenocytes.
3881 12639819 OM-197 upregulated the expression of HLA-DR, CD80, CD86, CD83, CD40 and CD54 at the surface of myeloid DC naturally present in blood as well as of DC generated in vitro from monocytes using IL-4 and GM-CSF.
3882 12639819 OM-197 also induced the release of IL-12 and TNF-alpha from DC.
3883 12639819 Finally, DC incubated with OM-197 after pulsing with hepatitis B surface antigen (HBs Ag) induced in vitro expansion of IFN-gamma-secreting HBs Ag-specific CD4(+) T lymphocytes from naive individuals.
3884 12641655 Peripheral blood monocytes were differentiated into immature DCs with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor, and pulsed with an immunogenic tetanus toxoid peptide.
3885 12641655 However, stimulation with antigen-pulsed DCs overexpressing IotakappaBetaalpha, the endogenous inhibitor of NF-kappaB, led to a significant reduction in T-cell proliferation, and decreased production of interferon-gamma, IL-4 and IL-10, whereas transforming growth factor-beta production was low throughout.

3888 12654796 Neonatal mice immunized with a single dose of vaccine in complete Freund's adjuvant (CFA) generated antigen-specific gamma interferon-, interleukin-2 (IL-2)-, IL-4-, and IL-5-secreting T cells in numbers similar to those in immunized adult mice, while vaccine administered to neonates in incomplete Freund's adjuvant (IFA) induced such cells in reduced numbers compared to those in adult mice.
3889 12654810 The Apa protein of Mycobacterium tuberculosis stimulates gamma interferon-secreting CD4+ and CD8+ T cells from purified protein derivative-positive individuals and affords protection in a guinea pig model.
3890 12654810 While traditionally the CD4(+) populations of T cells were believed to predominantly serve this protective function, a pivotal role for CD8(+) T cells in this task has been increasingly appreciated.
3891 12654810 We show that the 50- to 55-kDa Apa protein, specified by the Rv1860 gene of M. tuberculosis, can elicit both lymphoproliferative response and gamma interferon (IFN-gamma) production from peripheral blood mononuclear cells (PBMC) of purified protein derivative (PPD)-positive individuals, with significant differences recorded in the levels of responsiveness between PPD-positive healthy controls and pulmonary tuberculosis patients.
3892 12654810 Flow cytometric analysis of whole blood stimulated with the recombinant Apa protein revealed a sizeable proportion of CD8(+) T cells in addition to CD4(+) T cells contributing to IFN-gamma secretion.
3893 12654810 PBMC responding to the Apa protein produced no interleukin-4, revealing a Th1 phenotype.
3894 12667676 Immunohistological studies of liver sections revealed that, irrespective of the delivered peptide, cells infiltrating the liver towards microbeads were mainly CD3(+) T lymphocytes, both CD4(+) (70 to 80%) and CD8(+) (20 to 30%) subtypes, macrophages and dendritic cells.
3895 12667676 Cells infiltrating the granuloma had features of activated cells, with evidence of VLA-4 cell-surface expression, and production of IFN-gamma and IL-4.
3896 12669245 In vitro culture of immature DC generated from adherent peripheral blood mononuclear cells (PBMC) using granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4) with OK432 at various doses (0.01 to 0.1 KE/ml) for 2 days resulted in increased cell surface expression of CD80, CD83, CD86 and ICAM-1 in a dose-dependent manner.
3897 12669245 Assay of cytokine production in OK-DC after 2 days in culture revealed that OK432 was a strong inducer of IL-12 and interferon-gamma (IFN-gamma).
3898 12672905 We showed that BCG could promote cord blood monocyte-derived DC maturation by up-regulation of CD80, CD83, CD86, CD40, and MHC class II molecules and down-regulation of mannose receptor.
3899 12672905 BCG was able to induce similar levels of tumor necrosis factor-alpha and IL-10 but no bioactive IL-12p70 production from cord blood DCs as from adult blood DCs.
3900 12672905 Both non-BCG-treated and BCG-treated cord blood DCs efficiently induced a high level of IL-10, medium level of interferon-gamma, but little IL-4 production by cord blood naïve CD4+ T cells.
3901 12672905 Heat shock protein 65, a key component of BCG, had no effect on cord blood DC maturation in terms of CD86, MHC class II, and mannose receptor up-regulation.
3902 12682236 It is widely believed that generation of mature dendritic cells (DCs) with full T cell stimulatory capacity from human monocytes in vitro requires 5-7 days of differentiation with GM-CSF and IL-4, followed by 2-3 days of activation.

3916 12682236 The increase in intracellular calcium in response to 6Ckine showed that chemokine receptor 7 expression was functional.
3917 12696126 When spleen cells from mice immunized once with the vaccine and cholera toxin or its B subunit were restimulated with the live vaccine in vitro, there was greater thymidine uptake and production of interleukin- 2 (IL-2) than controls, but only a low level of IL-4 production.
3918 12697387 For in vitro cytokine release, immunization with pDNA-coated nanoparticles by jet injection enhanced IFN-gamma and IL-4 release over pDNA alone by 6- and 5-fold, respectively.
3919 12697387 SC injection of pDNA-coated nanoparticles also resulted in enhanced IFN-gamma and IL-4 release over pDNA alone although with less magnitude.

3989 12738640 Frequency of measles virus-specific CD4+ and CD8+ T cells in subjects seronegative or highly seropositive for measles vaccine.
3990 12738640 Little is known about cell-mediated immunity (CMI) to measles vaccine virus, the relative contribution of CD4(+) and CD8(+) T cells to variability in such immune responses, and the immunologic longevity of the CMI after measles vaccination in humans.

4007 12744869 Antigen entrapped in the escheriosomes leads to the generation of CD4(+) helper and CD8(+) cytotoxic T cell response.
4008 12744869 Our present study demonstrates that antigen encapsulated in escheriosomes could be successfully delivered simultaneously to the cytosolic as well as endosomal processing pathways of antigen presenting cells, leading to the generation of both CD4(+) T-helper and CD8(+) cytotoxic T cell response.
4009 12744869 In contrast, encapsulation of same antigen in egg phosphatidyl-choline (egg PC) liposomes, just like antigen-incomplete Freund's adjuvant (IFA) complex, has inefficient access to the cytosolic pathway of MHC I-dependent antigen presentation and failed to generate antigen-specific CD8(+) cytotoxic T cell response.
4010 12744869 Furthermore, antigen entrapped in escheriosomes stimulates antigen-specific CD4(+) T cell proliferation and also enhances the level of IL-2, IFN-gamma and IL-4 in the immunized animals.
4011 12744881 The interleukin 4 (IL-4), interferon gamma (IFNgamma) and IL-12 (p40 subunit) cytokine mRNA expression profiles in PBMC as well as lymphocyte proliferative response and the IgG2/IgG1 ratios specific for LACK suggest that in vaccinated animals there is triggering of cellular immune responses.
4012 12744885 Splenocytes from E7 gene vaccinated animals responded to re-stimulation in vitro with C3R cells by producing IL-4 but background levels of IFN-gamma.
4013 12750275 LAG-3 enables DNA vaccination to persistently prevent mammary carcinogenesis in HER-2/neu transgenic BALB/c mice.
4014 12750275 A stronger and enduring r-p185(neu)-specific cytotoxicity, a sustained release of IFN-gamma and interleukin 4, and a marked expansion of both CD8(+)/CD11b(+)/CD28(+) effector and CD8(+)/CD11b(+)/CD28(-) memory effector T-cell populations were induced in immunized mice.
4015 12759444 The PA-specific CD4(+) T cells from mice nasally immunized with rPA and CT as adjuvant secreted low levels of CD4(+) Th1-type cytokines in vitro, but exhibited elevated IL-4, IL-5, IL-6, and IL-10 responses.
4016 12761151 Thus, IL-4 and IL-5 are not essential for protection.
4017 12763481 TCC were then characterized for their ability to produce cytokines known to be important for T cell expansion (interleukin-2, IL-2) and/or effector functions (IL-4, IFN-gamma, IL-10).
4018 12771426 Lymphocytes obtained from the spleens of immunized and control mice were stimulated in vitro with JEV for 48 h and the supernatants were assayed for the presence of the cytokines IL-4 and IFN-gamma.
4019 12778487 Polarized Th1 cells (inducers) raised the frequency of IFN-gamma(+) cells within a naive (target) population, whereas Th2 inducers raised the frequency of IL-4(+) and reduced that of IL-2(+) cells.
4020 12782590 Immune-splenic lymphocytes when stimulated in vitro with 3H1 or CEA, showed increased proliferative CD4(+) Th1 type T-cell response and secreted significantly high levels of Th1 cytokines [IFN-gamma, interleukin (IL)-2] and low levels of Th2 cytokines (IL-4, IL-10).
4021 12782590 This vaccine also induced MHC class I antigen-restricted CD8(+) T-cell responses.
4022 12782590 The up-regulation of activation markers CD69 and CD25 on CD8(+) CTLs correlated with antigen-specific strong CTL responses in vitro.
4023 12791648 We found that both human and murine DCs pulsed with live fungi or transfected with fungal RNA underwent functional maturation, as revealed by the up-regulated expression of histocompatibility class II antigen and costimulatory molecules and the production of interleukin 12 (IL-12) in response to conidia or conidial RNA and of IL-4/IL-10 in response to hyphae or hyphal RNA.
4024 12794148 Both lymphotoxin-alpha and TNF are crucial for control of Toxoplasma gondii in the central nervous system.
4025 12794148 Immunity to Toxoplasma gondii critically depends on TNFR type I-mediated immune reactions, but the precise role of the individual ligands of TNFR1, TNF and lymphotoxin-alpha (LTalpha), is still unknown.
4026 12794148 Upon oral infection with T. gondii, TNF(-/-), LTalpha(-/-), and TNF/LTalpha(-/-) mice failed to control intracerebral T. gondii and succumbed to an acute necrotizing Toxoplasma encephalitis, whereas wild-type (WT) mice survived.
4027 12794148 Additionally, peritoneal macrophages produced reduced levels of NO upon infection with T. gondii and had significantly reduced toxoplasmastatic activity in TNF(-/-), LTalpha(-/-), and TNF/LTalpha(-/-) mice as compared with WT animals.
4028 12794148 Frequencies of parasite-specific IFN-gamma-producing T cells, intracerebral and splenic IFN-gamma production, and T. gondii-specific IgM and IgG titers in LTalpha(-/-) and TNF/LTalpha(-/-) mice were reduced only early after infection.
4029 12794148 In contrast, intracerebral IL-10 and IL-12p40 mRNA expression and splenic IL-2, IL-4, and IL-12 production were identical in all genotypes.
4030 12794148 In addition, TNF(-/-), LTalpha(-/-), and TNF/LTalpha(-/-), but not WT, mice succumbed to infection with the highly attenuated ts-4 strain of T. gondii or to a subsequent challenge infection with virulent RH toxoplasms, although they had identical frequencies of IFN-gamma-producing T cells as compared with WT mice.
4031 12794148 Generation and infection of bone marrow reconstitution chimeras demonstrated an exclusive role of hematogeneously produced TNF and LTalpha for survival of toxoplasmosis.
4032 12794148 These findings demonstrate the crucial role of both LTalpha and TNF for control of intracerebral toxoplasms.
4033 12798635 In all species so far studied, IgG isotype expression is controlled by Type 1 (IFN-gamma, IL-12) and Type 2 (IL-4, IL-10) cytokines which dictate immune response polarization to cell-mediated (CMI) or antibody-mediated immunity (AMI), respectively.
4034 12798635 Immunoglobulin isotype production by porcine B-cells cultured in the presence of recombinant porcine (rp) cytokines varies by individual, however pigs tend to generate a high IgG(1):IgG(2) ratio in response to rp IL-10 and the inverse in response to rp IFN-gamma or rp IL-12.
4035 12810878 This study shows that inactivated parapoxvirus ovis (Orf virus), strain D1701 (PPVO), induces an autoregulatory cytokine response that involves the upregulation of IL-12, IL-18, IFN-gamma and other T helper 1-type cytokines and their subsequent downregulation, which is accompanied by induction of IL-4.
4036 12810878 PPVO induces IL-12, TNF-alpha and, together with a suboptimal concentration of Concanavalin A, IFN-gamma in human peripheral blood leukocytes as well.
4037 12814694 Kinetics of the production of serum antibody levels and Th1 (IL-2, IFN-gamma) and Th2 (IL-4, IL-10) cytokines was studied in five pigs vaccinated with a synthetic tri-peptide vaccine (S3Pvac) against Taenia solium, a vaccine that has been shown protects pigs against naturally acquired infection.
4038 12814694 Peripheral blood mononuclear cells (PBMCs) of vaccinated pigs showed a significant increment in the production of Th1 cytokines (IL-2 and IFN-gamma) but not of Th2 cytokines (IL-4 and IL-10) after specific PBLs stimulation with all the individual peptides.
4039 12814694 Kinetics of the production of serum antibody levels and Th1 (IL-2, IFN-gamma) and Th2 (IL-4, IL-10) cytokines was studied in five pigs vaccinated with a synthetic tri-peptide vaccine (S3Pvac) against Taenia solium, a vaccine that has been shown protects pigs against naturally acquired infection.
4040 12814694 Peripheral blood mononuclear cells (PBMCs) of vaccinated pigs showed a significant increment in the production of Th1 cytokines (IL-2 and IFN-gamma) but not of Th2 cytokines (IL-4 and IL-10) after specific PBLs stimulation with all the individual peptides.
4041 12817004 Expansion of clonal populations of Ag (OVA and pigeon cytochrome c-specific) CD4(+) T cells was limited at higher precursor frequencies, presumably reflecting intraclonal competition.
4042 12817004 In contrast, a strong enhancement of the number of cells expressing IFN-gamma, IL-4, and IL-2 was observed in populations of cells at low precursor frequency in the presence of a high frequency of activated cells of a different Ag specificity.
4043 12817032 NOD recipient mice immunized with pDNA encoding a glutamic acid decarboxylase 65 (GAD65)-IgFc fusion protein (JwGAD65), IL-4 (JwIL4), and IL-10 (pIL10) exhibited an increased number of intact pro-islets expressing high levels of insulin 15 wk posttransplant, relative to NOD recipient mice immunized with pDNA encoding a hen egg lysozyme (HEL)-IgFc fusion protein (JwHEL)+JwIL4 and pIL10 or left untreated.
4044 12817032 Efficient protection of pro-islet grafts correlated with a marked reduction in GAD65-specific IFN-gamma reactivity and an increase in IL-10-secreting T cells.
4045 12819068 Induction of protective immunity against Schistosoma mansoni via DNA priming and boosting with the large subunit of calpain (Sm-p80): adjuvant effects of granulocyte-macrophage colony-stimulating factor and interleukin-4.
4046 12819068 In the present study, we have employed DNA immunization protocols using Sm-p80 with plasmids encoding granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4).
4047 12819068 Statistically, the protection conferred by including GM-CSF, but not IL-4, was significantly greater than that when only Sm-p80 was used.
4048 12819068 The introduction of GM-CSF DNA with Sm-p80 DNA led to distinct increases in total IgG and IgG1 titers, whereas the coadministration of IL-4 DNA with Sm-p80 DNA resulted in a slight elevation of IgG1 and IgG3 titers and in some reduction of IgG2A and IgG2B titers.

4061 12834622 Costimulatory function of umbilical cord blood CD14+ and CD34+ derived dendritic cells.
4062 12834622 Dendritic cells (DCs) consist of a heterogeneous population of hematopoietic cells characterized by their unique dendritic morphology, their efficient antigen-presenting capability to activate naive CD4(+) and CD8(+) T cells, and their lack of lineage specific markers.
4063 12834622 CD14(+) monocytes and CD34(+) stem cells were isolated from human umbilical cord blood and were induced to differentiate into dendritic cells using 100 ng/mL granulocyte-macrophage colony stimulating factor (GM-CSF), 25 ng/mL IL-4, 2.5 ng/mL tumor necrosis factor-alpha (TNF-alpha), 100 ng/mL GM-CSF, 25 ng/mL stem cell factor, and 2.5 ng/mL TNF-alpha, respectively.
4064 12834622 Flow cytometric analysis revealed that the 14-day-old dendritic cells were CD80(+), CD86(+), CD83(+), CD54(+), CD1a(+), CD11b(+), CD11c(+), HLA-DR(+), CD34(-), CD3(-), CD19(-), CD14(-), and CD16(-).
4065 12834622 Reverse transcription polymerase chain reaction was employed to detect expression of mRNA for CD80 and CD86.
4066 12834622 Differentiating monocytes initially expressed CD86 while CD80 appeared on day 2.
4067 12834622 Differentiating stem cells expressed CD80 and CD86 on day 2 of culture.
4068 12834622 The surface expression of CD80 and CD86 was studied over the course of differentiation.
4069 12834622 Prior to the functional assay, CD14(+) and CD34(+) derived DCs were stimulated for 18 h with 0.1 mg/mL and 1.0 mg/mL E. coli lipopolyssacharide, respectively.
4070 12834622 Monoclonal antibodies (mabs) to CD80 and CD86 were employed to assess their costimulatory roles.
4071 12834622 A decrease of stimulation as depicted by decreased T cell activation was significant with mabs to both CD80 and CD86 on monocyte-derived DCs while only mabs to CD86 induced decreased T cell activation by stem cell-derived DCs.
4072 12834622 The varied functional role of CD80 and CD86 costimulatory molecules is associated with DC differentiation from distinct cord blood isolated hematopoietic lineages.
4073 12842611 In a subset of ponies, lymphocytes from peripheral blood (PBLs), nasopharyngeal mucosal tissue, or lymph nodes (LNLs) were collected for measurement of influenza virus-specific lymphoproliferative responses, local antibody production and IL-2, IL-4 and IFN-gamma mRNA production by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR).
4074 12847225 IL-21 activates both innate and adaptive immunity to generate potent antitumor responses that require perforin but are independent of IFN-gamma.
4075 12847225 We show that IL-21 activates NK and CD8(+) T cells in vivo, thus mediating complete rejection of poorly immunogenic tumors.
4076 12847225 Rejection of IL-21-secreting tumors requires the presence of cognate IL-21R and does not depend on CD4(+) T cell help.
4077 12847225 Interestingly, perforin, but not IFN-gamma or other major Th1 and Th2 cytokines (IL-12, IL-4, or IL-10), is required for the IL-21-mediated antitumor response.
4078 12847242 Treatment of OVA-sensitized Nramp1(s) mice with M. vaccae suppressed airway hyperresponsiveness, airway eosinophilia, Ag-specific IgE, and IL-4 and IL-5 production after OVA aerosol challenge.
4079 12850480 Pre-clinical evaluation of this approach in murine models has demonstrated efficient anti-leukemic responses with the expression of immunomodulators, in particular GM-CSF and CD80, in irradiated cell vaccines.
4080 12850480 We have previously shown efficient insertion of GM-CSF and CD80 genes into primary human leukemia cells with the use of second and third generation self-inactivating (SIN) lentiviral vectors (Blood 96 (2000), 1317; Leukemia 16 (2002), 1645).
4081 12850480 In this work, we evaluated the insertion of the central polypurine tract and the central termination sequence into a SIN lentiviral vector encoding for GM-CSF and CD80, which significantly enhanced the transduction efficiency of primary leukemia cells and provided higher levels of GM-CSF and CD80 co-expression.
4082 12850480 We also demonstrate a methodology to deliver simultaneously a combination of immunomodulatory molecules (GM-CSF, CD80, IL-4, and CD40L) to activate different pathways of immune stimulation.
4083 12850495 Both interleukin-4 and CD40 ligand are important for optimal dendritic cell differentiation and maturation.

4094 12851699 Glioma-specific CTL activity was equivalently induced in the rats vaccinated s.c. with irradiated 9L, irradiated IL-2-producing 9L cells or the mixed population of irradiated 9L and C1300/IL-2 cells, while the activity was relatively lower in the rats vaccinated with irradiated 9L cells mixed with either C1300/IL-4 or C1300/GM-CSF cells.
4095 12851699 In the rats immunized s.c. with irradiated 9L cells, intracerebral (i.c.) 9L tumors implanted together with either C1300/IL-2 or C1300/IL-4 were completely rejected.
4096 12871175 In sera, we found reduced levels of both Interferon-gamma and Interleukin (IL)-4.
4097 12874015 DCs generated from peripheral blood using granulocyte macrophage colony-stimulating factor and interleukin (IL)-4 showed immunophenotypes consistent with immature DCs (iDCs).
4098 12874015 Furthermore, OK-DCs showed significantly higher production of IL-12 and IFN-gamma compared with DCs with other stimulations.
4099 12874015 Furthermore, OK-432 does not activate nuclear factor kappaB through Toll-like receptor 2 or Toll-like receptor 4 in the indicator cell system; however, it induces IL-12 production through the beta(2) integrin system on DCs.
4100 12874303 After 2 to 4 weeks, L. amazonensis-infected mice had significantly delayed and depressed expression of inflammatory cytokines (interleukin-12 [IL-12], gamma interferon, IL-1 alpha, IL-1 beta), CC chemokines (CC chemokine ligand 3 [CCL3]/macrophage inflammatory protein 1 alpha [MIP-1 alpha], CCL4/MIP-1 beta, CCL5/RANTES, MIP-2), and chemokine receptors (CCR1, CCR2, CCR5) in foot tissues and draining lymph nodes compared to the expression in L. major-infected controls.
4101 12874303 Studies with gene knockout mice suggested that IL-10, but not IL-4, contributed partially to compromised immunity in L. amazonensis-infected hosts.
4102 12874362 Rpf-like proteins elicit immunoglobulin G1 (IgG1) and IgG2a responses and T-cell proliferation and stimulate production of gamma interferon, interleukin-10 (IL-10), and IL-12 but not IL-4 or IL-5.
4103 12885891 Neutralizing antibodies against human RANTES, MIP-1alpha, MIP-1beta, alpha interferon (IFN-alpha), IFN-beta, IFN-gamma, interleukin-4 (IL-4), IL-10, IL-13, IL-16, MCP-1, MCP-3, tumor necrosis factor alpha (TNF-alpha), or TNF-beta failed to reverse the HIV-1-suppressive activity.

4152 12922080 Both IFN-gamma and IL-10, but not IL-4 were greatly elevated in the mesenteric lymph nodes whereas only IFN-gamma was increased in the peripheral lymph nodes, compatible with a TH1 cytokine response.
4153 12922130 To gain further insight into the cytokine production profile in response to measles vaccination, we studied interferon-gamma (IFN-gamma), tumor necrosis factor (TNF-alpha), soluble IL-2 receptor (sIL-2R), interleukin-2 (IL-2), interleukin-4 (IL-4), and interleukin-6 (IL-6) in both supernatants from peripheral blood mononuclear cells (PBMC) stimulated with phytohaemagglutinin (PHA), and plasma.
4154 12922130 However, plasma levels of Th1 cytokines (IFN-gamma, sIL-2R and TNF-alpha) were preferentially activated by measles virus after the first dose of measles vaccination.
4155 12924094 An experimental double immunization of BALB/c mice with a vaccine against tick-borne encephalitis was accompanied by the production of IL-1b, IL-2, IL-4, IL-6, IL-10, IL-12, TNFa and gamma-IFN in the blood serum of animals.
4156 12924094 After the second immunization and unlike the first one, there were changes in the production only of IL-10, IL-12 and gamma-IFN, which can be indicative of a regulation of balance between Th1 and Th2.
4157 12933826 In addition, the DNA vaccine elicited a T-cell-proliferative response and also induced the production of gamma interferon, but not interleukin-10 (IL-10) or IL-4, upon restimulation with either recombinant SOD or crude Brucella protein, suggesting the induction of a typical T-helper-1-dominated immune response in mice.
4158 12933862 Prior to challenge infection, immunization of genetically susceptible A/J mice with the combination of malaria antigen plus recombinant interleukin-12 (IL-12) in alum induced a Th1 immune response with production of high levels of gamma interferon (IFN-gamma) and diminished IL-4 levels by spleen cells stimulated in vitro with parasite antigen compared to mice immunized with antigen alone, antigen in alum, or antigen plus IL-12.
4159 12933862 Protective immunity was dependent on CD4(+) T cells, IFN-gamma, and B cells and was long-lasting.
4160 12940963 Such in vitro binding assays, using HLA DRB1* 0101, -0401, -0701 and -1101 alleles, demonstrated that two peptide sequences (DEEFNKKMQEQNAKFFADKP and FKHKFAELLEQQKAAQYPSK) exhibited high HLA DRB1* 0401 allele binding capacity. rKMP-11 specific T-cell proliferation and cytokine production, derived from 13 volunteers exposed to the parasite, suggested that using autologous DCs as APCs becomes advantageous in uncovering T-cell epitopes promoting proliferation and differences in IFN-gamma and IL-4 production in T-cells from volunteers with ACTIVE and CURED undetectable disease when other APCs were used.
4161 12941145 We found that oral or intranasal (i.n.) followed by i.m. immunizations induced significantly higher serum titres against NAP and CagA compared to i.n. alone, oral alone, i.m. alone, i.m. followed by i.n. or i.m. followed by oral immunizations.
4162 12941145 Any single route or combination of immunization routes with NAP and CagA preferentially induced antigen-specific splenic interleukin-4-secreting cells and far fewer interferon-gamma-secreting cells in the spleen.
4163 12946436 Retrovirus-transfected bone marrow cells cultured with GMCSF and IL-4 for 7 days demonstrated 70-80% of DCs with high CD11c, CD80, CD86, and MHC class I (I-Kd) expression.
4164 12946436 Immunization of DCs encoding SSP2 gene resulted in identification of two K(d) restricted CTL epitopes and induction of IFN-gamma-secreting cytolytic CD8+ T cells.
4165 12950681 Using antibody depletion and coculture systems, we show that rCTB directly costimulates KLH-specific CD4+ and CD8+ T-cell proliferation but not B cells.
4166 12950681 Enzyme-linked immunospot (ELISPOT) assays revealed that rCTB also enhanced the KLH-specific CD4+ T-cell-mediated production of interleukin-2 (IL-2), IL-4 and interferon-gamma(IFN-gamma) by four to fivefold.
4167 12950681 Together these data show that rCTB can act as a strong adjuvant, by directly costimulating antigen-primed CD4+ and CD8+ T cell in a dose-dependent manner.
4168 12952282 Immunohistochemistry with biopsy samples taken from the vaccine sites demonstrated that the infiltration level of CD4, CD8 and CD1a positive cells increased proportionally to the amount of IL-4 produced at the each site, suggesting that there was local immune response induced at the vaccine site.
4169 12957792 To understand the pathogenesis of vaccine-modified measles (VMM), we measured plasma levels of IFN-gamma and IL-2 (Th1 cytokines), IL-4 and IL-10 (Th2 cytokines), IL-12, TNF-alpha and TGF-beta1 in children with uncomplicated measles, who had anti-measles IgG antibodies and with a history of immunization on admission (day 0), day 14 and day 60.
4170 12957792 Plasma levels of IFN-gamma, IL-2 and IL-12 were significantly higher in VMM patients on day 0 compared to healthy controls (p = 0.023; p = 0.018; p = 0.001) respectively.
4171 12957792 Kinetically, IFN-gamma and IL-10 levels decreased consistently from day 0 to days 14 and 60 in VMM patients.
4172 12959322 During the course of HIV-1 infection secretion of T-helper type 1 (Th1) cytokines, such as interleukin (IL)-2, and antiviral interferon (IFN)-gamma, is generally decreased, whereas production of T helper type 2 (Th2) cytokines, IL-4, IL-10, proinflammatory cytokines (IL-1, IL-6, IL-8) and tumour necrosis factor (TNF)-alpha, is increased.
4173 12959322 HIV-inductive cytokines include: TNF-alpha, TNF-beta, IL-1 and IL-6, which stimulate HIV-1 replication in T cells and monocyte-derived macrophages (MDM), IL-2, IL-7 and IL-15, which upregulate HIV-1 in T cells, and macrophage-colony stimulating factor, which stimulates HIV-1 in MDM.
4174 12959322 HIV-suppressive cytokines include: IFN-alpha, IFN-beta and IL-16, which inhibit HIV-1 replication in T cells and MDM, and IL-10 and IL-13, which inhibit HIV-1 in MDM.
4175 12959322 Bifunctional cytokines such as IFN-gamma, IL-4 and granulocyte-macrophage colony-stimulating factor have been shown to have both inhibitory and stimulatory effects on HIV-1.
4176 12959322 The beta-chemokines, macrophage-inflammatory protein (MIP)-1alpha, MIP-1beta and RANTES are important inhibitors of macrophage-tropic strains of HIV-1, whereas the alpha-chemokine stromal-derived factor-1 suppresses infection of T-tropic strains of HIV-1.
4177 12959322 During the course of HIV-1 infection secretion of T-helper type 1 (Th1) cytokines, such as interleukin (IL)-2, and antiviral interferon (IFN)-gamma, is generally decreased, whereas production of T helper type 2 (Th2) cytokines, IL-4, IL-10, proinflammatory cytokines (IL-1, IL-6, IL-8) and tumour necrosis factor (TNF)-alpha, is increased.

4181 12959322 The beta-chemokines, macrophage-inflammatory protein (MIP)-1alpha, MIP-1beta and RANTES are important inhibitors of macrophage-tropic strains of HIV-1, whereas the alpha-chemokine stromal-derived factor-1 suppresses infection of T-tropic strains of HIV-1.
4182 12973030 Dendritic cells were generated from peripheral blood CD14+ precursors cultured in the presence of GM-CSF, IL-4, and 10% autologous serum.
4183 13679640 Although some groups isolate dendritic cells from peripheral blood, most have found it more efficient to generate large numbers from peripheral blood progenitors, particularly plastic adherent or CD14+ monocytes, in media supplemented with GM-CSF and IL-4.
4184 13680192 Combination of monocyte-derived dendritic cells and activated T cells which express CD40 ligand: a new approach to cancer immunotherapy.
4185 13680192 To develop the basis for a new DC-based cancer vaccine, we investigated cell-to-cell interactions between human monocyte-derived DCs and autologous T cells that are activated to express the CD40 ligand (CD40L).
4186 13680192 Peripheral blood monocytes were cultured in the presence of granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 4 (IL-4) to induce differentiation of DCs.
4187 13680192 Coculture of these DCs and ATs induced significant production of interleukin 12 (IL-12) and also enhanced the production of interferon gamma (IFN-gamma).
4188 13680192 Furthermore, coculture of DCs and ATs induced DCs to upregulate CD83 expression and stimulated migration of DCs toward the macrophage inflammatory protein 3-beta (MIP-3beta).
4189 14500496 In addition, after in vitro stimulation with rBLS, spleen cells from BLS-IFA-, BLS-Al-, or BLS-MPA-immunized mice proliferated and produced interleukin-2 (IL-2), gamma interferon (IFN-gamma), IL-10, and IL-4, suggesting the induction of a mixed Th1-Th2 response.
4190 14502281 IL-4 was crucial for the priming of vaccine-specific CD8(+) T cells, and we defined the primary source of IL-4 as a CD11b(+)CD11c(lo) phagocyte.
4191 14502281 Similarly, no IL-4 response or CD8(+) T-cell priming was seen in C1qa(-/-) mice.
4192 14502281 IL-4 was crucial for the priming of vaccine-specific CD8(+) T cells, and we defined the primary source of IL-4 as a CD11b(+)CD11c(lo) phagocyte.
4193 14502281 Similarly, no IL-4 response or CD8(+) T-cell priming was seen in C1qa(-/-) mice.
4194 14505892 More potent responses to two MHC class II epitopes, HIV gp160(843-852) or HIV gag(279-292), occurred in mice immunized with Ii-Key hybrid peptides than with epitope-only peptides, as measured in IL-4 and IFN-gamma ELISPOT assays of splenic lymphocytes stimulated in vitro by epitope-only peptides.
4195 14506743 Examination of the cytokines produced by these Th-cells showed that a majority of the proliferative p53-specific T cell cultures produced none of the key cytokines (IFNgamma, TNFalpha, IL-4, IL-5 or IL-10), indicating that these p53-specific Th-responses are not polarized.
4196 14506743 In patients who exhibited p53-specific reactivity against multiple p53-epitopes, non-polarized responses could be found side by side with polarized Th-responses that produced INFgamma or other cytokines such as IL-10.
4197 14512794 Autologous monocytes were harvested from a single apheresis and cultured for 7 days with granulocyte-macrophage colony-stimulating factor and interleukin-4, yielding immature dendritic cells (iDCs), which were then cryopreserved until use.
4198 14512794 In vitro, melanoma patient-derived dendritic cells (DCs) showed reduced cell surface expression of CD1a antigen on iDCs and reduced CD86 and HLA-DR expression on mDCs.
4199 14522457 The pattern of cytokine levels was in the following order: interferon-gamma>interleukin-2>interleukin-4.
4200 14530326 In the present study we evaluated the ability of a heat shock complex of HSP110 with the intracellular domain (ICD) of human HER-2/neu to elicit effective antitumor immune responses and to inhibit spontaneous mammary tumors in FVB-neu (FVBN202) transgenic mice.
4201 14530326 This vaccine induced ICD-specific IFN-gamma and IL-4 production.
4202 14530326 Depletion studies revealed that CD8(+) T cells were involved in protection against challenge with mouse mammary tumors, whereas CD4(+) T cells revealed partial protection.
4203 14530326 Increased IgG2a Ab titer in the sera of tumor-free animals after vaccination and elevated CD4(+) CD25(+) regulatory T cells in the PBL of tumor-bearing animals suggested that IFN-gamma-producing Th1 cells may be responsible for partial protection of CD4(+) T cells against the mammary tumor challenge, whereas CD4(+)CD25(+) regulatory T cells (Th2 cells) may suppress the antitumor immune responses.
4204 14530326 Together, these results suggest that HSP110-ICD complex can elicit effective IFN-gamma-producing T cells against spontaneous mammary tumors and that up-regulation of CD4(+) CD25(+) regulatory T cells may prevent complete eradication of the tumor following immunotherapy.

4235 14561701 Protection mediated by mAb's was associated with enhanced levels of IL-4, IL-6, and IFN-gamma in the lungs of infected mice.
4236 14561701 The antigen was identified as a histone H2B-like protein.
4237 14568420 Splenic cells from immunized mice secreted in vitro IFN-gamma, but not IL-4, after stimulation with Ole e 1.
4238 14575151 Analysis of Th2 induction in vitro indicates that this polarization develops gradually in T cells activated by anti-CD3 in the presence of IL-4; conversely anti-CD3 and IFNgamma induce Th1 cells.
4239 14594508 Differentiation of CD14(+) cells into mature monocyte-derived DC was induced by incubation with IL-4, GM-CSF, TNF-alpha, PGE(2), IL-1 beta, and IL-6.
4240 14594508 Mature DC showed a high expression of CD83, HLA-DR, and the co-stimulatory molecules CD80 and CD86.
4241 14600790 Nineteen patients received DCs plus autologous lysates and 14 patients DCs plus peptides from the melanoma antigens MAGE-3.A2, tyrosinase, gp100, and MART-1.
4242 14600790 DCs were produced from adherent cells in blood lymphocytes (monocytic DCs), grown in IL-4 and GM-CSF without a maturation step.
4243 14607876 Proliferating cells were lymphocytes, which mostly secreted interleukin 4 (IL-4) and IL-10 for the three serologic groups.
4244 14610620 Major mediators of anti-tumor immunity are CD4(+) T(h)1 cells and CD8(+) cytotoxic T lymphocytes (CTLs).
4245 14610620 IL-13 is one of the T(h)2 cytokines that has very similar features to IL-4 through sharing some receptor components and Stat6 signal transduction.
4246 14610620 It has been thought that IL-13 is not as critical for immune deviation as IL-4 since it cannot directly act on T cells.

4250 14613519 BACKGROUND: Allergic subjects produce relatively low amounts of IFN-gamma, a pleiotropic Th-1 cytokine that downregulates Th2-associated airway inflammation and hyperresponsiveness (AHR), the hallmarks of allergic asthma.
4251 14613519 Adenovirus-mediated IFN-gamma gene transfer reduces AHR, Th2 cytokine levels and lung inflammation in mice, but its use would be limited by the frequency of gene delivery required; therefore, we tested chitosan/IFN-gamma pDNA nanoparticles (CIN) for in situ production of IFN-gamma and its in vivo effects.
4252 14613519 Production of IFN-gamma is increased after CIN treatment while the Th2-cytokines, IL-4 and IL-5, and OVA-specific serum IgE are reduced compared to control mice.
4253 14613519 Experiments performed on STAT4-defective mice do not show reduction in AHR with CIN treatment, thus implicating STAT4 signaling in the mechanism of CIN action.
4254 14616120 The BCG vaccination improved lung function in both groups, and the Repeated BCG group showed a significant increase in the peripheral blood interferon gamma/interleukin 4 ratio.
4255 14616791 The LST and in vitro proliferative response (stimulation index, SI), interferon gamma (IFN-gamma) production and, in a few cases, interleukin (IL)-4 production of peripheral blood mononuclear cells to soluble Leishmania antigens were measured.
4256 14618088 The immunological events that lead to AD disease, the activation of the T-helper 2 (Th2) immune response, the synthesis of the cytokines IL-4, IL-5, IL-13, and the inhibition of the T-helper 1 (Th1) damage the capacity of the host to develop anti-VV cytotoxic cells (CTLs).
4257 14618645 We hypothesized that cytokines produced by asthmatic lung inflammation bias the immune response to antigens administered systemically toward a Th2 response, as assessed by serum IgE antibody and lymphocyte-secreted IL-4 and IL-5.
4258 14618645 The asthmatic population demonstrated an increased amount of Th2-mediated serum IgE anti-Hep B antibody, as compared to nonasthmatic children; but comparable amounts of IgG1, IgG2, IgG3, IgA, and IgM anti-Hep B antibody and lymphocyte IFNgamma, IL4, and IL5.
4259 14618645 We hypothesized that cytokines produced by asthmatic lung inflammation bias the immune response to antigens administered systemically toward a Th2 response, as assessed by serum IgE antibody and lymphocyte-secreted IL-4 and IL-5.
4260 14618645 The asthmatic population demonstrated an increased amount of Th2-mediated serum IgE anti-Hep B antibody, as compared to nonasthmatic children; but comparable amounts of IgG1, IgG2, IgG3, IgA, and IgM anti-Hep B antibody and lymphocyte IFNgamma, IL4, and IL5.
4261 14624382 To determine the effect of IL-12 supplementation, rhesus macaques were vaccinated with a recombinant MV expressing IL-12; these macaques had increased interferon-gamma production by CD4(+) T cells, decreased production of IL-4, and lower levels of MV-specific immunoglobulin G4 and neutralizing antibody.
4262 14627128 Immature monocyte-derived dendritic cells (imMo-DCs) isolated from human peripheral blood monocytes stimulated with granulocyte-macrophage colony stimulating factor and interleukin-4 were exposed to maturation factors, i.e., lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-alpha) plus prostaglandin E2 (PGE2), and OK-432 for 2 days.
4263 14627128 OK-432 increased expression of activation- and maturation-related molecules such as HLA-DR, CD80, CD83, and CD86 in imMo-DCs at levels similar to that of TNF-alpha plus PGE2, and higher than that of LPS.
4264 14627128 Only OK-432 caused significant production of interleukin-12 (IL-12) p70 and interferon gamma (IFN-gamma) at both the mRNA and protein levels in imMo-DCs.
4265 14627128 Neutralizing antibody against IL-12 p70 blocked IFN-gamma secretion from OK-432-stimulated Mo-DCs.
4266 14627128 IL-12 p70 produced by OK-432-stimulated imMo-DCs induced secretion of IFN-gamma by CD4+ T cells.
4267 14627128 Both secretion of IL-12 p70 and IFN-gamma and activation of NF-kappaB induced by OK-432 were suppressed when imMo-DCs were pretreated with cytochalasin B.
4268 14627128 These results indicate that uptake of OK-432 by imMo-DCs is an early critical event for IL-12 p70 production and that NF-kappaB activation induced by OK-432 also contributes partially to IL-12 p70 production.
4269 14629630 Peripheral blood mononuclear cells (PBMCs) obtained by leukapheresis were enriched for monocytes by immunomagnetic depletion of CD19+ B cells and CD2+ T cells employing the ISOLEX 300i device.
4270 14629630 After 5 days of culture of enriched monocytes in gas permeable Teflon bags, using serum-free medium supplemented with granulocyte/macrophage-colony stimulating factor and interleukin-4 (IL-4), immature DCs were generated.
4271 14629630 The generated matured transfected DCs show high expression of the antigens CD83, CD80, CD86 and human leucocyte antigen-DR.
4272 14635022 Antigen-specific cellular responses were characterized based on the balance of Th2 (IL-4, IL-5) and Th1 (IFN-gamma) cytokines in vitro.
4273 14635031 Active immunization with fibrillar beta-amyloid peptide (Abeta(42)) as well as passive transfer of anti-Abeta antibodies significantly reduces Abeta plaque deposition, neuritic dystrophy, and astrogliosis in the brain of mutant amyloid precursor protein (APP)-transgenic mice.
4274 14635031 We constructed a DNA minigene with Abeta fused to mouse interleukin-4 (pAbeta(42)-IL-4) as a molecular adjuvant to generate anti-Abeta antibodies and enhance the Th2-type of immune responses.
4275 14656542 Messenger RNA for interferon gamma (IFN-gamma), interleukin 2 (IL-2) and IL-4 was measured on days 0-10 by semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR) of RNA of LDL.
4276 14657224 Transforming growth factor-beta production and myeloid cells are an effector mechanism through which CD1d-restricted T cells block cytotoxic T lymphocyte-mediated tumor immunosurveillance: abrogation prevents tumor recurrence.
4277 14657224 Our previous work demonstrated that cytotoxic T lymphocyte (CTL)-mediated tumor immunosurveillance of the 15-12RM tumor could be suppressed by a CD1d-restricted lymphocyte, most likely a natural killer (NK) T cell, which produces interleukin (IL)-13.
4278 14657224 T cell-reconstituted recombination activating gene (RAG)2 knockout (KO) and RAG2/IL-4 receptor alpha double KO mice showed that inhibition of immunosurveillance requires IL-13 responsiveness by a non-T non-B cell.
4279 14657224 Such nonlymphoid splenocytes from tumor-bearing mice produced more transforming growth factor (TGF)-beta, a potent inhibitor of CTL, ex vivo than such cells from naive mice, and this TGF-beta production was dependent on the presence in vivo of both IL-13 and CD1d-restricted T cells.
4280 14657224 Further, blocking TGF-beta or depleting Gr-1+ cells in vivo prevented the tumor recurrence, implying that TGF-beta made by a CD11b+ Gr-1+ myeloid cell, in an IL-13 and CD1d-restricted T cell-dependent mechanism, is necessary for down-regulation of tumor immunosurveillance.
4281 14657224 Identification of this stepwise regulation of immunosurveillance, involving CD1-restricted T cells, IL-13, myeloid cells, and TGF-beta, explains previous observations on myeloid suppressor cells or TGF-beta and provides insights for targeted approaches for cancer immunotherapy, including synergistic blockade of TGF-beta and IL-13.
4282 14670333 IL-12 enhances protective immunity in mice engendered by immunization with recombinant 14 kDa Schistosoma mansoni fatty acid-binding protein through an IFN-gamma and TNF-alpha dependent pathway.
4283 14670333 Regarding other cytokines, significant amounts of IFN-gamma were measured in splenocyte culture supernatants of rSm14/IL-12 or rSm14 vaccinated mice and no IL-4 was detected.
4284 14670333 In an attempt to determine the role of IFN-gamma and TNF-alpha in IL-12 induced immunity, IFN-gamma and TNFR-p55 knockout mice were immunized with rSm14/IL-12 and no protection was achieved.
4285 14670333 Therefore, protection induced by rSm14/IL-12 was shown to be dependent on endogenous IFN-gamma and TNF-alpha.
4286 14671086 Peptide-specific cytokine responses and HLA-DRB1 allele associations revealed that, for the MV-P peptide, the allele with the strongest association with both IFN-gamma (P = 0.02) and IL-4 (P = 0.03) secretion was DRB1*0301.
4287 14671086 For MV-N, the allele with the strongest association with IFN-gamma secretion was DRB1*1501 (P = 0.04), and the alleles with the strongest associations with IL-4 secretion were DRB1*1103 and DRB1*1303 (P = 0.01).
4288 14671086 Peptide-specific cytokine responses and HLA-DRB1 allele associations revealed that, for the MV-P peptide, the allele with the strongest association with both IFN-gamma (P = 0.02) and IL-4 (P = 0.03) secretion was DRB1*0301.
4289 14671086 For MV-N, the allele with the strongest association with IFN-gamma secretion was DRB1*1501 (P = 0.04), and the alleles with the strongest associations with IL-4 secretion were DRB1*1103 and DRB1*1303 (P = 0.01).
4290 14671100 Immunization induced antibodies, peptide-specific gamma interferon (IFN-gamma), protein-specific lymphoproliferative responses, IFN-gamma, interleukin-2 (IL-2), and IL-4 T-helper responses in both vaccinees.
4291 14678262 Graves' hyperthyroidism and thyroiditis in HLA-DRB1*0301 (DR3) transgenic mice after immunization with thyrotropin receptor DNA.
4292 14678262 Two groups of mice were also coimmunized with plasmid DNA for IL-4 or GM-CSF.
4293 14685154 However, in EBV-positive Hodgkin's disease (HD) the efficacy of adoptively transferred EBV-specific CTL may be limited by tumor-derived immunosuppressive factors, such as T-cell growth factor (TGF) beta, interleukin (IL)13 and the chemokine TARC.
4294 14685154 EBV-specific CTL transduced with a retrovirus vector expressing the p40 and p35 subunits of IL12 as a single molecule (Flexi-IL12), produced IL12 following antigenic stimulation.
4295 14685154 This resulted in an elevated production of Th1 cytokines, including interferon gamma and tumor necrosis factor alpha, and a reduction in the Th2 cytokines IL4 and IL5.
4296 14685154 Flexi-IL12-transduced CTL resisted the antiproliferative and anticytotoxic effects of exogenous TGFbeta, likely by antagonizing the TGFbeta-induced downregulation of the Th1 transcriptional factor T-bet.
4297 14687950 On challenge, mice vaccinated initially with KV and boosted with either KV or LV expressed significantly skewed ratios of IL-4 to IFN-gamma mRNA and IgG1 to IgG2a antibody, when compared to those vaccinated initially with LV.
4298 14688338 Third, the application of cholera toxin to the intact skin of NOD/Lt mice, with or without insulin B peptide 9-23, exacerbated insulitis and T lymphocyte-derived IFN-gamma and IL-4 production in the islets of Langerhans, resulting in an increased incidence and rate of onset of autoimmune diabetes.
4299 14688363 IL-23 induces stronger sustained CTL and Th1 immune responses than IL-12 in hepatitis C virus envelope protein 2 DNA immunization.
4300 14688363 In this study, we investigated whether IL-23 could influence envelope protein 2 (E2)-specific cell-mediated immunity induced by immunization of hepatitis C virus E2 DNA.
4301 14688363 Interestingly, IL-23N220L, an N-glycosylation mutant showing reduced expression of excess p40 without changing the level of IL-23, exhibited a higher ratio of IFN-gamma- to IL-4-producing CD4(+) T cell frequency than did wild-type IL-23, suggesting a negative regulatory effect of p40 on Th1-prone immune response induced by IL-23.
4302 14704372 T cells from mice immunized with antigen in the presence of CT produced high levels of interleukin (IL)-10 and IL-5 and low levels of IL-4 and interferon-gamma (IFN-gamma).
4303 14704372 Here, we demonstrate that immunization with antigen in the presence of CT induced a population of antigen-specific CD4(+) T cells that produced IL-10 in the absence of IL-4, in addition to cells that coexpressed IL-4 and IL-10 or produced IL-4 only.
4304 14704372 Previous data showed that CT can modulate the expression of costimulatory molecules and inhibit the production of chemokines and cytokines, including IL-12 and tumor necrosis factor alpha and enhance IL-10 production.
4305 14704372 Here, we show that CT synergizes with LPS to induce IL-6 and IL-1beta in addition to IL-10 production by immature DC.
4306 14704372 T cells from mice immunized with antigen in the presence of CT produced high levels of interleukin (IL)-10 and IL-5 and low levels of IL-4 and interferon-gamma (IFN-gamma).

4310 14708863 Proliferation, cytokine profile in culture supernatants from antigen-stimulated peripheral blood mononuclear cells and specific IgG1, IgG3, IgG4, IgA, IgM & IgE levels were assessed.
4311 14708863 The evaluation of the cytokine profile [IL-2, IL-4 & IFN-gamma] in response to this antigen showed a significant increase as demonstrated by ELISA.
4312 14708863 Specifically, IFN-gamma and IL-2 were significantly detected by flow cytometry.
4313 14712315 Tumor cells were transfected with murine granulocyte-macrophage colony-stimulating factor (GM-CSF) or IL-4 plasmids employing the cationic lipid DOTAP, were irradiated (150 Gy) and kept frozen until use.
4314 14712315 While cell clones secreting GM-CSF were the most effective in wild-type tumor cell rejection, little or no effect was observed with clones secreting IL-4.
4315 14712315 Tumor cells were transfected with murine granulocyte-macrophage colony-stimulating factor (GM-CSF) or IL-4 plasmids employing the cationic lipid DOTAP, were irradiated (150 Gy) and kept frozen until use.
4316 14712315 While cell clones secreting GM-CSF were the most effective in wild-type tumor cell rejection, little or no effect was observed with clones secreting IL-4.
4317 14735319 In this pilot study, we have used the peptide-pulsed dendritic cells (DCs) generated from peripheral blood mononuclear cells (PBMCs) supplemented with GM-CSF and IL-4 as the source of the vaccine.
4318 14735319 Furthermore, A24/CEA peptide tetramer assay revealed an increase in peptide-specific T-cell precursor frequency in vaccinated patients.
4319 14739648 The studies on allergen-induced Th2 cells revealed that the Th2 cytokine IL-4 induces B cells to synthesize IgE, and cytokine IL-5 is the inducer of eosinophilia, just as in HIV-1 infection.
4320 14740954 Little interleukin-4 (IL-4) or IL-10 secretion was detected, indicating a T(H)1 type of T cell response.
4321 14740954 T cell depletion studies showed that the interferon-gamma was being secreted by CD4+ T lymphocytes and/or by cells other than CD8+ T lymphocytes that were being stimulated by the CD4+ T lymphocytes.
4322 14740954 CD3+ or CD8+ T cell depletion showed that granzyme B mRNA expression correlated with the presence of CD4+ T lymphocytes.
4323 14740954 However, depletion of CD4+ T cells after four days of stimulation indicated that the granzyme B mRNA was produced by cells in culture other than lymphocytes.
4324 14750178 CD4+ T cell-mediated HER-2/neu-specific tumor rejection in the absence of B cells.
4325 14750178 We asked whether B cells/antibodies are needed for tumor immunity induced by plasmid (HER-2 and GM-CSF) immunization.
4326 14750178 HER-2 specific tumor immunity relied completely on both CD4+ and CD8+ T cells.
4327 14750178 IFN-gamma, and to a lesser extent IL-4, seemed to be crucial cytokines during tumor rejection.
4328 14770083 In a murine model of experimental bladder cancer, intravesical instillation of rBCG-IFNgamma resulted in an enhanced recruitment of CD4+ T-cells into the bladder and further induced the local expression of IL-2 and IL-4 cytokines (mRNA) compared to control rBCG.
4329 14969600 Serum samples obtained prior to (week 0) and after three vaccinations (week 4) were assayed for interleukin (IL)-2, interferon (IFN)-gamma, IL-4, and IL-10.
4330 14969600 Results (mean +/- SD) for 30 patients who had matching serum samples obtained at weeks 0 and 4 were: week 0, IL-2, 122 +/- 320 pg/mL; IFN-gamma, 0.1 +/- 0.4 IU/mL; IL-4, 10.0 +/- 19 pg/mL; IL-10, 159 +/- 237 pg/mL; week 4: 119 +/- 308 for IL-2; 0.1 +/- 0.4 for IFN-gamma; 16 +/- 29 for IL-4, and 210 +/- 273 for IL-10.

4334 14971031 DC progenitors can be stimulated to differentiate into immature DC by various growth factors, including GM-CSF and IL-4.
4335 14971031 Here we show that IL-15, in combination with GM-CSF, is a growth factor for murine DC.
4336 14971031 Murine bone marrow cells, depleted of T cells, B cells, I-A+ cells and Gr-1+ granulocytes, and cultured in the presence of GM-CSF plus IL-15 (IL-15 DC), yielded DC expressing high levels of CD11c and MHC class II molecules, as well as CD11b.
4337 14971031 These cells expressed significant levels of CD40, CD80 and CD86, and could stimulate allogeneic CD4+ T cells efficiently.
4338 14971031 Interestingly, IL-15 DC were far superior to DC generated with GM-CSF plus IL-4 in stimulating allogeneic CD8+ T cells in vitro.
4339 14971031 Consistent with this, IL-15 DC induced much more potent antigen-specific CD8+ T cell responses with high levels of Th1 cytokines in vivo, compared to DC generated with GM-CSF plus IL-4, or with GM-CSF plus TGF-beta, or with GM-CSF alone.
4340 14971031 Together, these data suggest that IL-15 promotes the development of DC, which induce potent Th1 and Tc1 responses in vivo.

4357 14984494 Retroviral transduction of acute myeloid leukaemia-derived dendritic cells with OX40 ligand augments their antigen presenting activity.
4358 14984494 In the present study, we examined whether the transduction of leukaemia-DCs with OX40 ligand (OX40L), a member of the tumour necrosis factor (TNF) family, resulted in augmentation of their antigen presenting activity.
4359 14984494 Fresh leukaemic cells from five patients with acute myeloid leukaemia (AML) were isolated and retrovirally transduced with OX40L during the culture with a combination of cytokines from stem cell factor, fms-like tyrosine kinase (Flt)-3 ligand, granulocyte-macrophage colony stimulating factor (GM-CSF), interleukin-4 (IL-4) and TNF-alpha.
4360 14984494 After 7 d, the majority of cells showed DC-like morphology, and expressed higher levels of CD80, CD86 and HLA-DR than fresh leukaemic cells.
4361 14984494 Co-culture of allogeneic CD4+ T cells with OX40L-transduced leukaemia-DCs was superior in the generation of interferon (IFN)-gamma producing CD4+ T cells and in production of IFN-gamma.
4362 14984598 However, CD8low T cells express IFN-gamma and substantial amounts of IL-4, the signature cytokines of type 1 and type 2 T-cell polarization, respectively.
4363 14984598 Here, we argue that the CD8low phenotype is an alternative career choice for any naive CD8+ T cell during primary activation but that the probability of choosing this option is greatly enhanced by both IL-4 and strong activation conditions.

4366 14997036 In particular, we focused on peripheral blood Th1/Th2 balance by measuring intracellular production of IFN-gamma, IL-2 (Th1), IL-4 (Th2), and IL-10 by CD4 T cells, using a nested case control study design within a large epidemiological survey.
4367 14997036 In particular, ongoing Th1-type immune activation was associated with multisymptom illness in GWVs, with sick veterans having significantly elevated levels of IFN-gamma and IL-2 producing CD4+ cells in the absence of in vitro stimulation compared with wGWVs (P = 0.01 and P =0.001).
4368 14997038 We showed previously that DC derived from a monocyte subset expressing CD16 (16+mDC) stimulated allogeneic naïve T lymphocytes to secrete higher levels of IL-4 than DC derived from regular CD14(high)CD16(-) monocytes (16-mDC).
4369 14997038 Before treatment, the IFN-gamma/IL-4 ratio against TuLy and KLH was higher when using 16-mDC as APC, but after vaccination four of five patients had an increased ratio for TuLy with 16+mDC.
4370 14997038 We showed previously that DC derived from a monocyte subset expressing CD16 (16+mDC) stimulated allogeneic naïve T lymphocytes to secrete higher levels of IL-4 than DC derived from regular CD14(high)CD16(-) monocytes (16-mDC).

4372 14999431 The vaccine used mature DCs (CD1a+++, CD40++, CD80++, CD83+, and CD86+++) generated from peripheral blood monocytes in the presence of GM-CSF and IL-4.
4373 14999431 After 7 days, DCs were matured with a defined cocktail of cytokines (IL-1+IL-6+TNF-alpha+PGE2) and simultaneously pulsed with lysates of heterologous melanoma cell lines, for 2 days.
4374 15003644 Production of both IFN-gamma and IL-4 by splenic T cells, and serum IgG1 and IgG2a, suggest induction of a mixed Th1/Th2 response following immunization.
4375 15003644 Increased production of NO and IFN-gamma by spleen cells, and down regulation of IL-4, demonstrate that an initial stimulation of a mixed Th1/Th2 response by vaccination instructs Th1 responses and resistance against a progressive infection by L. donovani.

4382 15004163 Nasal Flt3 ligand cDNA elicits CD11c+CD8+ dendritic cells for enhanced mucosal immunity.
4383 15004163 In addition, significant levels of OVA-specific CD4+ T cell proliferative responses and OVA-induced IL-4 and IL-2 production were noted in spleen and cervical lymph nodes.
4384 15004163 Further, marked increases in FL protein occurred in the nasal lamina propria and submandibular glands and the frequencies of CD11c+CD8+ dendritic cells (DCs) significantly increased in the mucosal tissues.
4385 15004163 Moreover, these DCs expressed high levels of CD40, CD80, CD86, and MHC class II molecules.
4386 15004184 In response to leishmanial Ag stimulation, cells from lpg2--infected mice produced minimal levels of IL-4 and IL-10, as well as very low levels of IFN-gamma.
4387 15010829 DCs were generated from the patients' autologous monocyte-enriched fractions of granulocyte colony-stimulating factor-mobilized peripheral blood mononuclear cells in the presence of granulocyte/macrophage colony-stimulating factor and interleukin-4.
4388 15013994 Three ophthalmic sponges, Weck-Cel, Ultracell, and Merocel, were loaded in vitro with interleukin-1 beta (IL-1 beta), IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-15, IL-18, gamma interferon (IFN-gamma), granulocyte-macrophage colony-stimulating factor (GM-CSF), immunoglobulin A (IgA), or IgG, and sponges were extracted and evaluated for total recovery by enzyme-linked immunosorbent assay (ELISA).
4389 15013994 There was excellent (>75%) recovery for all immune markers from all three devices except for IL-6, which was poorly recovered (<60%) for all sponge types, IFN-gamma, which was poorly recovered from both Weck-Cel and Ultracell sponges but was completely recovered from Merocel sponges, and IL-4, which was poorly recovered from Weck-Cel sponges but was completely recovered from Ultracell or Merocel sponges.
4390 15013994 We then compared the absolute recovery of selected markers (IL-10, IL-12, IgG, and IgA) from cervical secretion specimens collected from women using each type of sponge.
4391 15013994 There were no significant differences in the recoveries of IL-10, IL-12, and IgG from cervical specimens collected by any type of ophthalmic sponge, but there was reduced IgA recovery from Merocel sponges.
4392 15013994 We infer from our data that the three collection devices are adequate for the measurements of IL-1 beta, IL-2, IL-5, IL-12, IL-15, IL-18, and IgG.
4393 15013994 Merocel may be a better ophthalmic sponge for the collection of cervical secretions and measurements of IL-4, IL-8, IL-10, GM-CSF, and IFN-gamma, but our data from clinical specimens, not in vitro-loaded sponges, suggested the possibility of reduced recovery of IgA.

4406 15015780 Subcutaneous vaccination using granulocyte-macrophage colony-stimulating factor (GM-CSF)-transduced glioma cells substantially prolongs survival in the mouse GL261 glioma model.
4407 15015780 To potentiate the efficacy of GM-CSF-based vaccination, syngeneic C57BL/6 mice bearing pre-implanted intracerebral GL261 gliomas were vaccinated twice subcutaneously with various combinations of glioma cells retrovirally engineered to release GM-CSF, interleukin (IL)-4 or macrophage inflammatory protein (MIP)-1alpha.
4408 15015780 More than 80% of the animals vaccinated with GM-CSF-secreting or GM-CSF- and IL-4-secreting cells were long-term survivors (> 120 days).
4409 15015780 The combination of IL-4 with GM-CSF did not provide a survival advantage over GM-CSF alone, regardless of whether the animals carried a small or large intracranial tumor load.
4410 15015780 Further, when the animals were vaccinated with a mixture of GM-CSF-, IL-4- and MIP-1alpha-secreting cells, the median survival was 37 days, and only 22% of the animals in this group were long-term survivors, similar to the vaccination effect of non-modified glioma cells.
4411 15015780 Thus, unexpectedly, the co-expression of MIP-1alpha, which was meant to attract T cells for stimulation by GM-CSF- and IL-4-stimulated dendritic cells, nullified the induction of an immune response against the GL261 glioma by a GM-CSF- and IL-4-expressing subcutaneous vaccine.

4423 15015780 Thus, unexpectedly, the co-expression of MIP-1alpha, which was meant to attract T cells for stimulation by GM-CSF- and IL-4-stimulated dendritic cells, nullified the induction of an immune response against the GL261 glioma by a GM-CSF- and IL-4-expressing subcutaneous vaccine.
4424 15015780 Subcutaneous vaccination using granulocyte-macrophage colony-stimulating factor (GM-CSF)-transduced glioma cells substantially prolongs survival in the mouse GL261 glioma model.
4425 15015780 To potentiate the efficacy of GM-CSF-based vaccination, syngeneic C57BL/6 mice bearing pre-implanted intracerebral GL261 gliomas were vaccinated twice subcutaneously with various combinations of glioma cells retrovirally engineered to release GM-CSF, interleukin (IL)-4 or macrophage inflammatory protein (MIP)-1alpha.
4426 15015780 More than 80% of the animals vaccinated with GM-CSF-secreting or GM-CSF- and IL-4-secreting cells were long-term survivors (> 120 days).
4427 15015780 The combination of IL-4 with GM-CSF did not provide a survival advantage over GM-CSF alone, regardless of whether the animals carried a small or large intracranial tumor load.
4428 15015780 Further, when the animals were vaccinated with a mixture of GM-CSF-, IL-4- and MIP-1alpha-secreting cells, the median survival was 37 days, and only 22% of the animals in this group were long-term survivors, similar to the vaccination effect of non-modified glioma cells.

4430 15015780 Subcutaneous vaccination using granulocyte-macrophage colony-stimulating factor (GM-CSF)-transduced glioma cells substantially prolongs survival in the mouse GL261 glioma model.
4431 15015780 To potentiate the efficacy of GM-CSF-based vaccination, syngeneic C57BL/6 mice bearing pre-implanted intracerebral GL261 gliomas were vaccinated twice subcutaneously with various combinations of glioma cells retrovirally engineered to release GM-CSF, interleukin (IL)-4 or macrophage inflammatory protein (MIP)-1alpha.
4432 15015780 More than 80% of the animals vaccinated with GM-CSF-secreting or GM-CSF- and IL-4-secreting cells were long-term survivors (> 120 days).

4435 15015780 Thus, unexpectedly, the co-expression of MIP-1alpha, which was meant to attract T cells for stimulation by GM-CSF- and IL-4-stimulated dendritic cells, nullified the induction of an immune response against the GL261 glioma by a GM-CSF- and IL-4-expressing subcutaneous vaccine.
4436 15016855 Interestingly, one animal that was completely protected from infection had the strongest IFN-gamma and interleukin-2 (IL-2) responses prior to challenge, in addition to very strong IL-4 responses to Gag and Env.
4437 15016857 Role of interleukin-4 (IL-4) and IL-10 in serum immunoglobulin G antibody responses following mucosal or systemic reovirus infection.
4438 15016857 However, we observed that mRNA for the T helper 2 cytokine IL-10 was suppressed in the Peyer's patches and mesenteric lymph nodes and IL-4 mRNA was suppressed in the mesenteric lymph nodes compared to noninfected controls, following oral infection.
4439 15016857 Role of interleukin-4 (IL-4) and IL-10 in serum immunoglobulin G antibody responses following mucosal or systemic reovirus infection.
4440 15016857 However, we observed that mRNA for the T helper 2 cytokine IL-10 was suppressed in the Peyer's patches and mesenteric lymph nodes and IL-4 mRNA was suppressed in the mesenteric lymph nodes compared to noninfected controls, following oral infection.
4441 15039330 Intraspleen delivery of a DNA vaccine coding for superoxide dismutase (SOD) of Brucella abortus induces SOD-specific CD4+ and CD8+ T cells.
4442 15039330 Animals vaccinated with pcDNA-SOD did not develop SOD-specific antibodies, at least until week 4 after immunization (the end of the experiment), and in vitro stimulation of their splenocytes with either recombinant Cu-Zn SOD or crude Brucella protein induced the secretion of gamma interferon (IFN-gamma), but not interleukin-4, and elicited the induction of cytotoxic-T-lymphocyte activity.
4443 15039330 Upon analyzing the SOD-specific T-cell responses, the pcDNA-SOD vaccination was found to be stimulating both CD4(+)- and CD8(+)-T-cell populations.
4444 15039330 However, only the CD4(+) population was able to produce IFN-gamma and only the CD8(+) population was able to induce cytotoxic activity.
4445 15039330 Based on these results, we conclude that i.s. immunization with pcDNA-SOD vaccine efficiently induced a Th1 type of immune response and a protective response that could be related to IFN-gamma production and cytotoxic activity against infected cells by SOD-specific CD4(+) and CD8(+) T cells, respectively.
4446 15045561 Peripheral blood mononuclear cells (PBMC) isolated from vaccinated macaques were stimulated with inactivated viral particles for 24 h, and the production of IL-2, IL-4, IL-6, IL-10, IL-12, TNF-alpha and IFN-gamma was determined by ELISA and flow cytometry.
4447 15047852 For this study, we used DNA-based immunizations to elicit gamma interferon-producing (Tc1) or interleukin 4 (IL-4)-producing (Tc2) CD8 T cells to the influenza virus nucleoprotein.
4448 15057902 Further associations were observed with single nucleotide polymorphisms (SNPs) at the IL2 and IL4 loci along with insertion/deletion variants at the IL12B locus (P =.003-.01).
4449 15057902 Host genetic associations were independent of one another as well as other HLA (A, B, C, and DQB1) and cytokine gene (IL4R, IL6, IL10, and TNF) variants.
4450 15061718 Unlike humans, the blastogenic as well as cytokine responses (IFN-gamma, IL-2 and IL-4) to Con A was considerably higher as compared to PHA.
4451 15064826 Resistance in visceral leishmaniasis involves both CD4+ and CD8+ T cells, and interleukin (IL)-2, interferon (IFN)-gamma, and IL-12, the latter in a mechanism independent of IFN-gamma and linked to transforming growth factor (TGF)-beta production.
4452 15064826 Susceptibility involves IL-10 but not IL-4, and B cells.
4453 15064826 In immune animals, upon re-infection, the elements involved in resistance are different, i.e., CD8+ T cells and IL-2.
4454 15064826 Interactions of the co-stimulatory molecule family B7-CTLA-4 leading to increased level of TGF-beta as well as apoptosis of CD4+ T cells and inhibition of macrophage apoptosis by Leishmania infection are other components participating in immunosuppression.
4455 15068861 In contrast, mice vaccinated with sgp120-mC3d-DNA had splenocytes that secreted both IL-4 and interferon-gamma (INF-gamma) indicating a mixed T helper response.
4456 15068864 Imiquimod was found to increase the number and maturation status of dendritic cells in draining lymph nodes, and to enhance antigen-specific CD4(+) and CD8(+) T cell responses, as assessed by analyses of clonal expansion, and the quantity and kinetics of cytokine production from these cells in lymph nodes and spleens collected after vaccination.
4457 15068864 A more substantial increase in IFN-gamma-producing, compared with IL-4-producing CD4(+) T cells suggested that imiquimod biased the immune response towards a predominance of Th1 cells.
4458 15076142 Phase I trial of antigen-specific gene therapy using a recombinant vaccinia virus encoding MUC-1 and IL-2 in MUC-1-positive patients with advanced prostate cancer.
4459 15076142 The purpose of this phase 1 clinical trial was to determine the maximum tolerated dose, safety of a multiple-dose regimen, and the immunologic effect of vaccinia virus expressing MUC-1 and IL-2 genes (VV/MUC-1/IL-2) in patients with advanced prostate cancer.
4460 15076142 Systemic immune modulation in this patient included (1) up-regulation of IL-2 (CD25) and T cell (TcR alphabeta) receptors, (2) increase in the CD4/CD8 ratio (2.5-fold) (3) augmentation of T-helper type 1 cell (TH1) (interferon-gamma and tumor necrosis factor-alpha) but not TH2 (IL-4) cytokine mRNA expression, (4) induction of natural killer cell activity and MHC independent MUC-1 specific cytotoxic T-cell activity, and (5) normalization of mRNA expression of T-cell-associated signal transduction molecules TcR-zeta and p56lck.
4461 15076142 These results suggest that VV/MUC-1/IL-2 gene therapy with a maximum tolerated dose of 5 x 10(7) pfu is safe and well tolerated.
4462 15083197 We constructed a recombinant adenovirus expressing the full-length cDNA of HCA661 gene and then transduced immature DCs, which had been generated with GM-CSF and IL-4 from peripheral blood mononuclear cell of HLA-A2(+) healthy donors.
4463 15083197 The resulting adenovirus-transduced DCs differentiated in the presence of monocyte-conditioned medium and poly [I] : poly [C], expressing the surface markers of mature DCs, including CD83, CD80, CD86 and HLA-DR.
4464 15099757 Dendritic cell-like cells (Mo-DCs) generated from peripheral blood monocytes with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor (GM-CSF) have been used as tools to treat cancer patients (DC-vaccines).
4465 15099757 In addition, we collected Mo-DCs from the collagen gels by collagenase treatment and analyzed the expression of antigen presentation-related molecules such as HLA-DR, CD80, CD83, and CD86 on Mo-DCs.
4466 15115073 The expression of SjC23 and p35, p40 in muscle tissue was determined by immunohistochemical method.
4467 15115073 By culture of spleen cells, the production of IL-2, IL-4, IL-10 and IFN-gamma with the stimulation of specific antigen of the recombinant hydrophilic domain of SjC23 (rSjC23-HD) was determined after the last immunization (before challenge).
4468 15115073 The results showed that SjC23 and p35, p40 of mouse IL-12 were expressed on the membrane and in the plasma of the muscle cells of immunized C57BL/6 mice.
4469 15115073 A rise of IL-2 and IFN-gamma in the SjC23 group and SjC23+IL-12 group was observed; No changes were found in IL-4 and IL-10.
4470 15115073 The expression of SjC23 and p35, p40 in muscle tissue was determined by immunohistochemical method.
4471 15115073 By culture of spleen cells, the production of IL-2, IL-4, IL-10 and IFN-gamma with the stimulation of specific antigen of the recombinant hydrophilic domain of SjC23 (rSjC23-HD) was determined after the last immunization (before challenge).
4472 15115073 The results showed that SjC23 and p35, p40 of mouse IL-12 were expressed on the membrane and in the plasma of the muscle cells of immunized C57BL/6 mice.
4473 15115073 A rise of IL-2 and IFN-gamma in the SjC23 group and SjC23+IL-12 group was observed; No changes were found in IL-4 and IL-10.
4474 15122523 Increased pulmonary expression of interleukin (IL)-4, IL-5, and IL-13 mRNA and aggravated alveolitis and hypertrophy of mucus-producing cells were observed only when OVA-sensitized mice were inoculated with RSV shortly before or during challenge with OVA.
4475 15122754 HCs upregulate surface expression of major histocompatibility complex (MHC) class I molecules and CD1d but not MHC class II molecules Qa-1, CD80, CD86, CD54, or CD95; in addition, they expressed/secreted interleukin (IL)-10 and IL-4 but not IL-1, IL-6, IL-13, interferon (IFN)-gamma, tumor necrosis factor (TNF), IL-4, or IL-27 (i.e., they acquire the HC* phenotype).
4476 15122754 HCs* (but not HCs) induced specific activation, proliferation, and IFN-gamma, TNF, and IL-13 release of cocultured naïve CD8(+) T cells.
4477 15122754 Only recently activated CD8(+) T blasts (but not recently activated CD4(+) T blasts or activated cells of the innate immune system, including natural killer T [NKT] cells) induced the HC* phenotype that is prominent from day 10 to day 20 postvaccination (i.e., time points at which peak numbers of recently primed CD8(+) T blasts are found in the liver).
4478 15146294 Primed DCs were assessed by the in vitro activation of B3Z OVA-specific CD8 T cells and the proliferation of OVA-specific CD8 and CD4 T cells from OT-I and OT-II TCR transgenic mice, respectively.
4479 15146294 Quantification of IL-2, IL-4, IL-5, IFN-gamma, and TNF-alpha by cytometric bead array (CBA) assay determined the polarization of TH1/TH2 responses, whereas H-2 Kb/SIINFEKL tetramers monitored the expansion of OVA-specific T cells.
4480 15146294 The hybrids also induced the most potent CTLs, offered the highest protection against established EG7 tumors and also induced the highest stimulation of IFN-gamma and TNF-alpha production.
4481 15147040 These analyses revealed that the expansion of antigen specific CD8+T cells is the most effective when T cells were activated by fully maturated DCs by culturing monocytes for 5 days in the presence of GM-CSF and IL-4, followed by 2-3 days of maturation with pro-inflammatory mediators including TNFalpha, IL-6, IL-1beta and PGE2.
4482 15147576 Modulation of immune responses to bovine herpesvirus-1 in cattle by immunization with a DNA vaccine encoding glycoprotein D as a fusion protein with bovine CD154.
4483 15147576 The objective of this study was to determine whether a DNA vaccine encoding bovine CD154 linked to a truncated version of bovine herpesvirus-1 (BHV-1) glycoprotein D (tgD-CD154) induces enhanced tgD-specific immune responses in cattle.
4484 15147576 In vitro characterization demonstrated that tgD and tgD-CD154 both bind to cultured bovine B cells, whereas only tgD-CD154 induces interleukin-4-dependent proliferation, suggesting that tgD-CD154 specifically binds the CD40 receptor and induces receptor signalling.

4486 15158774 Adult-like in vitro cytotoxicity against hRSV-infected targets and precursor cytotoxic T cell frequencies were observed within one week of neonatal priming and hRSV-ISCOM A-primed neonates showed virtually complete protection against subsequent viral challenge. hRSV challenge was associated with some pulmonary eosinophilia in both age groups, with higher IL-4 production by lung CD4+ T cells in mice primed as neonates.
4487 15161079 To examine the effects of cytokine environment at the time of antigenic exposure on T-cell cytokine profiles following T-cell-antigen presenting cell (APC) interaction, pig monocyte-derived dendritic cells (mDCs) were treated with hen egg white lysozyme (HEWL) or killed Mycobacterium tuberculosis (Mtb) alone or with a recombinant pig cytokine (TNF-alpha, interleukin (IL)-12, IL-10, interferon (IFN)-gamma or IL-6) and then incubated with autologous T-cell-enriched lymphocytes.
4488 15161079 Messenger RNA was isolated from the T-cells and used to evaluate the effects of treatment on IL-12p35, IFN-gamma, IL-4, IL-10 and IL-13 expression using RT-PCR.
4489 15161079 T-cells exposed to HEWL-treated mDCs expressed high IL-13 and moderate IL-10 and IFN-gamma, suggesting T-helper 2 (Th-2) bias.
4490 15161079 Addition of any cytokine during HEWL treatment of mDCs reduced subsequent expression of IL-10 and IL-13 by T-cells.
4491 15161079 Added IL-12 increased IFN-gamma mRNA.
4492 15161079 T-cells exposed to Mtb-treated mDCs expressed increased IFN-gamma and decreased IL-10 suggesting Th-1 bias.
4493 15161079 Addition of cytokines to mDCs treated with Mtb altered T-cell cytokine mRNA expression such that TNF-alpha, IFN-gamma or IL-12 increased IFN-gamma; IL-12 and IFN-gamma suppressed IL-10, while IL-10 and IL-12 enhanced IL-13.
4494 15162431 Similar to naive CD4 T cells, Thpp cells expressed IL-2 but not the cytokines characteristic of differentiated Th1 or Th2 cells, such as IFN-gamma, IL-4, or IL-5.
4495 15162431 However, Thpp, Th1 and Th2 cells, but not naive cells, expressed several CC chemokines including CCL1/TCA3, CCL5/RANTES, CCL3/MIP-1 alpha, CCL4/MIP-1 beta, and CCL9/MIP-1 gamma.
4496 15162438 RNA interference technology has been used to modulate dendritic cell (DC) function by targeting the expression of genes such as IL-12 and NF-kappa B.
4497 15162438 Inhibition of IL-10 by siRNA was accompanied by increased CD40 expression and IL-12 production after maturation, which endowed DC with the ability to significantly enhance allogeneic T cell proliferation.
4498 15162438 IL-10 siRNA transfection did not affect MHC class II, CD86, CD83, or CD54 expression in mature DC.
4499 15162438 To further test the ability of IL-10 siRNA-treated DC to induce a T cell response, naive CD4 T cells were stimulated by autologous DC pulsed with KLH.
4500 15162438 The results indicated that IL-10 siRNA-transfected DC enhanced Th1 responses by increasing IFN-gamma and decreasing IL-4 production.
4501 15173014 Immunoprevention of HER-2/neu transgenic mammary carcinoma through an interleukin 12-engineered allogeneic cell vaccine.
4502 15173014 Repeated vaccinations with cells engineered to release interleukin (IL)-2, IL-12, IL-15, or IFN-gamma showed that IL-12-engineered cell vaccines had the most powerful immunopreventive activity, with >80% of 1-year-old BALB-neuT mice free of tumors.
4503 15173014 The IL-12-engineered cell vaccine elicited a high production of IFN-gamma and IL-4 and a strong anti-HER-2/neu antibody response.
4504 15173014 The protection afforded by the IL-12-engineered cell vaccine was equal to that provided by the systemic administration of recombinant IL-12 in combination with HER-2/neu H-2(q) cell vaccine.
4505 15173014 However, IL-12-engineered cell vaccine induced much lower circulating IL-12 and IFN-gamma, and therefore lower potential side effects and systemic toxicity.
4506 15181281 Thus, interleukin-4 (IL-4) is known to induce IL-4 production in T cells; conversely IL-12 and interferon-gamma (IFN-gamma) are known to induce IFN-gamma production by T cells.
4507 15195249 Notable observations were that the lymphocytes obtained from the vaccinated mice proliferated and secreted mainly interferon- gamma and IgG2a, but not interleukin-4 and IgG1.
4508 15198641 Differences between both groups suggest that in order for 'preimmune' mice to survive a lethal challenge, a predominantly TH2-type response is required, with a higher mRNA expression level of IL-4 and IL-10, and a lower mRNA expression of IFN-gamma.
4509 15203922 Regarding cellular immunity, high levels of IFN-gamma and no IL-4 were detected in primed mouse splenocytes and partial protection against infection was reached in animals vaccinated with the Brucella library compared to the control group.
4510 15213150 In contrast, LTK63, LTR72, and LTwt significantly augmented NadA-specific gamma interferon, interleukin-4 (IL-4), IL-5, and IL-10 production by spleen and lymph node cells, suggesting that both Th1 and Th2 cells were induced in vivo.
4511 15218165 A series of mutated open reading frames encoding F proteins that lacked the entire pep27, that contained an arbitrarily chosen 23 aa sequence instead of pep27 or in which pep27 was replaced by the amino acid sequences for the bovine cytokines interleukin 2 (boIL2), interleukin 4 (boIL4) or gamma interferon (boIFN-gamma) was constructed.
4512 15225293 BALB/c mice immunized with a total soluble antigen of T. gondii (TSA2) mixed with ODN-containing CpG sequences developed a typical TH1 response, as determined by antibody isotypes and interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) production by spleen cells.
4513 15225296 To better characterize protective cellular immunity, E. ruminantium-specific IFN-gamma and IL-4 recall responses in major T-cell subsets were analysed by flow cytometry during immunization of goats with a killed vaccine and following a virulent challenge.
4514 15225296 The killed vaccine elicited both CD8+ and CD4+ subsets to produce cytoplasmic IFN-gamma in the absence of IL-4, thus indicating a biased T1 response.
4515 15225296 The relative capacity of CD8+ T-cells to produce IFN-gamma was significantly higher than CD4+ T-cells but the final contribution of both subsets was comparable.
4516 15225296 Circulating ER-specific CD4 and CD8 effectors substantially decreased in numbers after the booster injection and could not be detected in most animals during challenge, which warrants further investigation in immune compartments other than blood.
4517 15225296 To better characterize protective cellular immunity, E. ruminantium-specific IFN-gamma and IL-4 recall responses in major T-cell subsets were analysed by flow cytometry during immunization of goats with a killed vaccine and following a virulent challenge.
4518 15225296 The killed vaccine elicited both CD8+ and CD4+ subsets to produce cytoplasmic IFN-gamma in the absence of IL-4, thus indicating a biased T1 response.
4519 15225296 The relative capacity of CD8+ T-cells to produce IFN-gamma was significantly higher than CD4+ T-cells but the final contribution of both subsets was comparable.
4520 15225296 Circulating ER-specific CD4 and CD8 effectors substantially decreased in numbers after the booster injection and could not be detected in most animals during challenge, which warrants further investigation in immune compartments other than blood.
4521 15240755 We found that monocytes infected with BCG differentiate into CD1a- DCs (BCG-DCs) in the presence of granulocyte macrophage-colony stimulating factor and interleukin (IL)-4 and acquired a mature phenotype in the absence of maturation stimuli.
4522 15240755 In addition, BCG-DCs produced proinflammatory cytokines (tumor necrosis factor alpha, IL-1beta, IL-6) and IL-10 but not IL-12.
4523 15242811 Human monocytes were cultured with GM-CSF and IL-4 for 6 days, followed by another 2 days in the presence of M1, M4 or TNF-alpha as a maturation stimulus.
4524 15242811 Stimulation with 20 microM of M1 or M4 increased expression level of CD80, CD83 and CD86 as expressed by mean fluorescence intensity (MFI) and decreased endocytic activity.
4525 15242811 In CTL assay, the production of IFN-gamma and 51Cr release on M4-primed mature DCs was more augmented than of immature DCs or TNF-alpha-primed mature DCs.
4526 15242946 Additionally, coadministration of pCtB enhanced the production of interleukin-2 and gamma interferon by spleen cells but did not affect the production of interleukin-4, suggesting a Th1-type helper response.
4527 15253152 We found that both humoral and Th1-type (high IFN-gamma, low IL-4) cellular responses obtained from the divalent DNA vaccine group were significantly higher than that conferred by BCG.
4528 15270734 Treatment of animals with B. pertussis DNA significantly decreased the Th2 cytokine (interleukins IL-4 and IL-5) concentrations in the airways without increasing Th1 cytokines.
4529 15270735 Notably, there was a reduction in levels of interleukin (IL)-5 and IL-13 produced by systemic Der p 1 reactive CD4(+) Th2 cells on in vitro stimulation as well as in IL-4 and IL-5 levels in BAL fluid.
4530 15270841 However, DNA vaccination encoding microbial or reporter antigens is known to induce specific long-lasting CD4 Th1 and strong cytolytic CD8 T cell responses.
4531 15270841 Simultaneously, DNA immunization induced GAD-specific CD4 T cells secreting interleukin (IL)-4 (P < 0.05) and transforming growth factor (TGF)-beta (P = 0.03).
4532 15270841 Furthermore, vaccination produced high amounts of Th2 cytokine-related IgG1 (P < 3.10(-3)) and TGF-beta-related IgG2b to GAD (P = 0.015).
4533 15270841 Surprisingly, diabetes onset was correlated positively with Th2-related GAD-specific IgG1 (P < 10(-4)) and TGF-beta-related IgG2b (P < 3.10(-3)).
4534 15271379 We describe the use of a recently developed technique, real-time quantitative RT-PCR, to quantify several Aotus monkey cytokine mRNAs involved in Th1/Th2 responses (IL-4, IL-10, TNF-beta and IFN-gamma).
4535 15279716 Dendritic cells were derived from freshly isolated monocytes after 7 days of culture with IL-4 and granulocyte-macrophage colony-stimulating factor, pulsed with autologous tumor RNA, and then cryopreserved.
4536 15293452 Spleen cells collected from plasmid-vaccinated BALB/c mice produced PA-specific interleukin-4, interleukin-5, and interferon-gamma in vitro.
4537 15294176 We investigated the feasibility of using N-terminal rat neu DNA immunization on mouse tumor overexpressing endogenous p185neu and enhancing the therapeutic efficacy of this vaccine by fusion to various cytokine genes, including interleukin-2 (IL-2), interleukin-4 (IL-4), or granulocyte-macrophage colony-stimulating factor.
4538 15294176 In a therapeutic model, N'-neu-IL-2 DNA vaccine was significantly better than N'-neu DNA vaccine, and N'-neu DNA vaccine was significantly better than control DNA or N'-neu-IL-4 DNA vaccine.
4539 15294176 Depletion of CD8+ T cells completely abolished the therapeutic effects of N'-neu-IL-2 DNA vaccine and N'-neu DNA vaccine.
4540 15294176 Depletion of CD4+ T cells after tumor implantation had no influence on N'-neu-IL-2 DNA vaccine, but enhanced the therapeutic efficacy of N'-neu DNA vaccine.
4541 15294176 Depletion of CD4+ T cells or fusion to the IL-2 gene can thus further enhance the therapeutic effects of N'-neu DNA immunization on mouse tumor expressing endogenous p185neu.
4542 15294176 We investigated the feasibility of using N-terminal rat neu DNA immunization on mouse tumor overexpressing endogenous p185neu and enhancing the therapeutic efficacy of this vaccine by fusion to various cytokine genes, including interleukin-2 (IL-2), interleukin-4 (IL-4), or granulocyte-macrophage colony-stimulating factor.
4543 15294176 In a therapeutic model, N'-neu-IL-2 DNA vaccine was significantly better than N'-neu DNA vaccine, and N'-neu DNA vaccine was significantly better than control DNA or N'-neu-IL-4 DNA vaccine.
4544 15294176 Depletion of CD8+ T cells completely abolished the therapeutic effects of N'-neu-IL-2 DNA vaccine and N'-neu DNA vaccine.
4545 15294176 Depletion of CD4+ T cells after tumor implantation had no influence on N'-neu-IL-2 DNA vaccine, but enhanced the therapeutic efficacy of N'-neu DNA vaccine.
4546 15294176 Depletion of CD4+ T cells or fusion to the IL-2 gene can thus further enhance the therapeutic effects of N'-neu DNA immunization on mouse tumor expressing endogenous p185neu.
4547 15294987 When aged mice were immunized with PV PSVs encoding human IL-2, specific Th cells were generated, producing murine IL-2, IL-4, and IFN-gamma.
4548 15295005 In the presence of GM-CSF, TNF-alpha, and/or IL-4, leukemia-derived DC are obtained that display features of immature DC (i-DC).
4549 15295005 Using CD40L as maturating agent, we show that leukemic i-DC can differentiate into cells that fulfill the phenotypic criteria of m-DC and, compared with normal counterparts, are functionally competent in vitro in terms of: 1) production of cytokines that support T cell activation and proliferation and drive Th1 polarization; 2) generation of autologous CD8(+) CTLs and CD4(+) T cells that are MHC-restricted and leukemia-specific; 3) migration from tissues to lymph nodes; 4) amplification of Ag presentation by monocyte attraction; 5) attraction of naive/resting and activated T cells.
4550 15312141 In addition, splenocytes from ISS-ODN but not C-ODN treated mice displayed attenuated OVA-specific interleukin (IL)-4, IL-5, and IL-13 but increased interferon-gamma responses.
4551 15314040 Furthermore, the UV-inactivated virion induced regional lymph node T-cell proliferation and significant levels of cytokine production (IL-2, IL-4, IL-5, IFN-gamma and TNF-alpha) upon restimulation with inactivated SARS-CoV virion in vitro.
4552 15315840 The latter included the shifting in serum levels of IL4 and IL5 to IL2 suggesting a switching from a T helper 2 (Th2) to a T helper 1 (Th1) subset.
4553 15315856 Nasal immunization of mice with ovalbumin (OVA) plus the Stx1-B or mStx1 induced OVA-specific serum IgG and mucosal IgA responses.
4554 15315856 IgG subclass analysis revealed that mStx1 and Stx1-B as mucosal adjuvants supported Ag-specific IgG1 followed by IgG2b Abs.
4555 15315856 The co-administration of either mStx1 or Stx1-B with OVA enhanced the production of IL-4, IL-5, IL-6 and IL-10 with low IFN-gamma, by OVA-specific CD4+ T cells.
4556 15315856 To better elucidate the mechanisms underlying mStx1's and Stx1-B's adjuvant activity, we next sought to examine whether or not dendritic cells (DC) residing in the nasopharyngeal-associated lymphoreticular tissue (NALT) were activated by nasal administration of Stx1-B or mStx1.
4557 15315856 We found that mice nasally administered with Stx1-B or mStx1 showed an up-regulation in the expression of CD80, CD86 and especially CD40 on NALT DCs.
4558 15315856 Taken together, these results suggest that non-toxic Stx derivatives could be effective mucosal adjuvants for the induction of Th2-type, CD4+ T cell mediated, antigen-specific mucosal IgA and systemic IgG Ab responses, and that they likely owe their adjuvant activity to the up-regulation of co-stimulatory molecules including CD80, CD86 and CD40 on NALT DCs.
4559 15315860 We tested the capacity of peripheral blood lymphocytes from 121 health care professionals, including 76 non-responders, to proliferate to four HBV vaccines, examined the proliferating cells' subset, production of IFN-gamma, IL-4 and IL-10, and for 22 subjects, the cytokine production genotype.
4560 15315861 However, neither IL-4 nor IL-5 was produced in any of the groups.
4561 15317270 We have investigated the effects of Parietaria-SIT on rhinitis symptoms, BHR to inhaled methacholine, eosinophilic inflammation and cytokine production (interferon gamma and interleukin-4) in the sputum.

4563 15322030 Here we show that, by contrast, maturation-arrested DC in vitro are capable of the successful induction of antigen-specific gamma interferon (IFN-gamma) and interleukin 4 (IL-4) T-cell responses, antibody responses, and potent protection against lethal blood-stage malaria challenge in vivo.
4564 15322030 Antibody-independent, T-cell- and IL-12-associated protection was observed early after immunization, followed by antibody and IL-4-associated, IFN-gamma-independent protection in long-term studies.
4565 15322030 Here we show that, by contrast, maturation-arrested DC in vitro are capable of the successful induction of antigen-specific gamma interferon (IFN-gamma) and interleukin 4 (IL-4) T-cell responses, antibody responses, and potent protection against lethal blood-stage malaria challenge in vivo.
4566 15322030 Antibody-independent, T-cell- and IL-12-associated protection was observed early after immunization, followed by antibody and IL-4-associated, IFN-gamma-independent protection in long-term studies.
4567 15331695 Compared to mice immunized with SHIV VLPs alone, mice coimmunized with SHIV VLPs and inactivated influenza virus showed significant increases in serum immunoglobulin G (IgG) and mucosal IgA antibodies specific to the human immunodeficiency virus envelope protein, neutralizing activities, numbers of gamma interferon- and interleukin 4-secreting lymphocytes, and cytotoxic-T-lymphocyte activities.
4568 15342937 Selective generation of different dendritic cell precursors from CD34+ cells by interleukin-6 and interleukin-3.
4569 15342937 Several cytokines, especially stem cell factor (SCF) and FLT3-ligand (FL), have been identified as essential to produce large numbers of myeloid precursors and even to increase DC yield obtained by the action of granulocyte-macrophage colony-stimulating factor (GM-CSF) and tumor necrosis factor alpha (TNF-alpha).
4570 15342937 We report here that in the absence of serum, SCF, FL, and thrombopoietin (TPO) plus interleukin-6 (IL-6) and SCF, FL, and TPO plus IL-3 were able to generate CD14+CD1a- and CD14- CD1a+ myeloid DC precursors from CD34+ cells, but IL-6 had an inhibitory effect on the generation of CD14- CD1a+ cells.
4571 15342937 Both DC precursors differentiated into mature DCs by GM-CSF, IL-4, and TNF-alpha, and DCs obtained from both types of culture exhibited equal allostimulatory capacity.
4572 15342937 CD1a+ DCs generated could be identified on the basis of DC-specific intracellular adhesion molecule-grabbing nonintegrin (DC-SIGN) expression, a novel C-type lectin receptor expressed on dermal DCs but not on Langerhans cells.
4573 15342937 In addition, the inclusion of IL-3 to the culture medium induced the appearance of CD13- cells that differentiated into plasmacytoid DC (DC2) on the addition of TNF-alpha, allowing the identification of developmental stages of DC2.
4574 15356430 Urinary tract diseases revealed after DTP vaccination in infants and young children: cytokine irregularities and down-regulation of cytochrome P-450 enzymes induced by the vaccine may uncover latent diseases in genetically predisposed subjects.
4575 15356430 It is suggested that the whole-cell pertussis present in DTP vaccine, acting as an excessive stimulus in these patients, produced symptoms reminiscent of biologic responses to circulating proinflammatory monokines such as IL-1beta, TNF-alpha, and IL-6 because earlier it was reported that in vitro the whole-cell vaccine induced significantly more such cytokine production than did the acellular pertussis or diphtheria-tetanus-only vaccine.
4576 15356430 Analysis of the cellular immune disturbances previously reported in urinary tract infection/inflammation (increased serum and/or urinary IL-1alpha, IL-1 receptor antagonist, IL-6 and IL-8), steroid-sensitive nephrotic syndrome (increased IL-2, IFN-gamma, TNF-alpha, and decreased or increased IL-4, depending on the cells studied), and atopic dermatitis (decreased IFN-gamma and increased IL-4 production), may suggest that similar subclinical chronic cytokine-mediated abnormalities produced in the course of latent diseases revealed in our patients, combined with those caused by DTP vaccination stimulus, were responsible for the pathomechanism of these clinical entities.
4577 15356430 This speculation is in agreement with the reports on the long-lasting induction of cytokine release and down-regulation of hepatic cytochrome P-450 isoenzyme activities after administration of DTP vaccine to mice and may be supported by the fact that TH1 phenotype is associated with the up-regulation of intercellular adhesion molecule-1 and RANTES, whereas TH2 phenotype is associated with the up-regulation of the vascular cell adhesion molecule and P-selectin, which are key players in the migration into inflamed tissues and localization of lymphocytes and other allergic effector and inflammatory cells.
4578 15356430 Because several inflammatory cytokines down-regulate gene expression of major cytochrome P-450 and/or other enzymes with the specific effects on mRNA levels, protein expression, and enzyme activity, thus affecting the metabolism of several endogenous lipophilic substances such as steroids, lipid-soluble vitamins, prostaglandins, leukotrienes, thromboxanes, and exogenous substances, their irregularities in the body may eventually lead to the flare of latent diseases in some predisposed subjects.
4579 15356430 Also, interleukin genetic polymorphisms, especially the constellation of TNF-alpha and IL-6 genetic variants, might predispose some infants with infection to a more than usually intense inflammatory response in the kidneys after vaccination.
4580 15357215 There was a preferential production of IFN-gamma compared to IL-4, which indicated the induction of a protective Th1 response, by the DNA vaccine.
4581 15359643 Peripheral blood CD14+ monocytes from multiple myeloma (MM) patients can be induced to differentiate into fully functional, mature, CD83+ dendritic cells (DCs) which are highly efficient in priming autologous T lymphocytes in response to the patient-specific tumor idiotype (Id).
4582 15359643 Cells were then cultured, according to Good Manufacturing Practice guidelines, in FCS-free medium in cell culture bags, and differentiated to DCs with GM-CSF plus IL-4 followed by TNF-alpha or, more recently, by a cocktail of IL-1beta, IL-6, TNF-alpha and prostaglandin-E2.
4583 15359643 Notably, the cytokine cocktail induced a significantly higher percentage and yield (31+/-10.9 of initial CD14+ cells) of DCs than TNF-alpha alone, secretion of larger amounts of IL-12, potent stimulatory activity on allogeneic and autologous T cells.
4584 15364433 In a first stage, the immune response elicited by the intramuscular injection of a mixture of four plasmid DNAs, encoding the L. infantum histones H2A, H2B, H3 and H4, was determined in BALB/c mice.
4585 15364433 It was found that the immunized animals developed a specific Th1 immune response, which was associated with an antigen-specific production of interferon (IFN-gamma) and a limited humoral response against histones (dominated by antibodies of the IgG2a isotype).
4586 15364433 The protection in mice vaccinated with histone-DNAs was associated with a low humoral response against leishmanial antigens, an enhanced IFN-gamma production and little, if any, IL-4 production.
4587 15364433 The relative contribution of both CD8(+) and CD4(+) T cells to the IFN-gamma production, and the IL-12 dependence were also evaluated.
4588 15364433 All these data indicated that DNA vaccination with Leishmania histones genes results in a specific Th1-like response during L. major infection, and that both CD4(+) and CD8(+) T cells contribute to the resistance of vaccinated mice to cutaneous leishmaniasis.
4589 15364448 We demonstrate a strong positive association between TT-specific cellular immunity as evidenced by increased IL-4, IL-5 and IL-13 responses, and maternal TT-specific IgG.
4590 15385477 Lymphocytes from animals in the PvMSP-1(42)- and PvMSP-1(19)-immunized groups showed proliferative responses upon stimulation with the respective antigens, and high levels of interleukin-4 (IL-4), IL-5, and gamma interferon were detected in the culture supernatants.
4591 15385926 Real-time PCR confirmed higher expression of genes for IL-2 and IFN-gamma in T cells stimulated with Apo-DC.
4592 15385926 Concurrently, no IL-10 and low IL-4 responses indicated that the immune response was primarily of the Th1 type.
4593 15456623 The cytokine profile (interleukin [IL]-4, 5, 10 and 2, interferon [IFN-gamma], and tumor necrosis factor [TNF-alpha]) was determined before the start of treatment and at the end of follow-up (4-5 months).
4594 15456623 Levels of IL-4, 5 and 10 (Th2 profile) decreased while those of IL-2, IFN-gamma, and TNF-alpha (Th1 profile) decreased.
4595 15456623 The cytokine profile (interleukin [IL]-4, 5, 10 and 2, interferon [IFN-gamma], and tumor necrosis factor [TNF-alpha]) was determined before the start of treatment and at the end of follow-up (4-5 months).
4596 15456623 Levels of IL-4, 5 and 10 (Th2 profile) decreased while those of IL-2, IFN-gamma, and TNF-alpha (Th1 profile) decreased.
4597 15458778 Stat 6(-/-) mice which are unable to utilise the type 2 cytokines IL-4 and IL-13 and so should have reduced IgG1 responses were utilised in order to determine whether an immune system biased towards the type 1 axis could mount an effective response to the vaccine.
4598 15474968 Human monocyte-derived DC (MoDC) generated in vitro in the presence of GM-CSF and IL-4 are regarded equivalent to immature DC.
4599 15482515 Spontaneous interleukin (IL)-4 and interferon (IFN)-gamma production from duodenal specimens were measured, and the inflammatory cells were quantitated in specimens from different sections of the GI tract.
4600 15482515 Administration of BCG simultaneously with BLG resulted in reduced IgE concentration in serum, while the specific IgG(1) and IgG(2a) antibody responses and the spontaneous secretion of IL-4 and IFN-gamma were not affected.
4601 15482515 Spontaneous interleukin (IL)-4 and interferon (IFN)-gamma production from duodenal specimens were measured, and the inflammatory cells were quantitated in specimens from different sections of the GI tract.
4602 15482515 Administration of BCG simultaneously with BLG resulted in reduced IgE concentration in serum, while the specific IgG(1) and IgG(2a) antibody responses and the spontaneous secretion of IL-4 and IFN-gamma were not affected.
4603 15482516 Interleukin (IL)-4 and interferon (IFN)-gamma measured in the supernatant of stimulated cultured blood mononuclear cells did not change in the BCG group (10.8 +/- 2.3 vs. 17.9 +/- 5.7 pg/ml, and 348.6 +/- 118.0 vs. 354.8 +/- 139.0 pg/ml, respectively), while in the control group IL-4 increased (from 6.7 +/- 1.3 to 16.1 +/- 6.0 pg/ml, p < 0.05), and IFN-gamma decreased (from 279.9 +/- 82.1 to 232.1 +/- 109.6 pg/ml, p = 0.01).
4604 15494483 We used 12-color flow cytometry to characterize Ag-specific T cells elicited by vaccines or natural infection to determine lineage and differentiation status as well as the capacity to produce four cytokines (IFN-gamma, TNF-alpha, IL-2, and IL-4) and a chemokine (MIP1beta).
4605 15496383 Anti-CD3 stimulation of reconstituted T-cells showed 'mean' levels of CD4 and CD25 were enhanced by 34.5 and 31.1 % in immunized mice, which was comparable to 53.2 and 50.7 %, respectively, in challenged-immunized mice, and were dominant over CD8+ T-cells.
4606 15496383 Macrophage migration inhibition factor (MIF) and IL4 responses during anti-CD3 stimulation of immunized mice indicated that the role of anti-CD3 in generation of O2- is due to a synergistic effect by Th1 subsets of Th0 cells.
4607 15496603 FN had higher numbers and percentages of memory/effector (M/E) cytotoxic/suppressor (CD45R0(+)CD8(+), RMA) T, Fas(+) M/E (CD45R0(+)CD95(+)CD3(+), 6 mo) T, and CD56(+)CD16(-) NK cells (CD56(+)CD16(-)CD3(-)CD8(-), 12 mo), and higher percentages of M/E helper (CD45R0(+)CD4(+), RMA) T, Tc1 (IFN gamma(+)CD4(-)CD3(+), RMA), total interferon (IFN)gamma T (IFN gamma(+)CD4(+/-)CD3(+), RMA), Th2 (IL-4(+)CD4(+)CD3(+), 7 mo), and CD57(+) NK-T cells (CD57(+)CD56(-)CD3(+), 6 mo, 7 mo) compared with F.
4608 15496603 Percentages of naive helper T (CD45RA(+)CD4(+), 12 mo) and numbers and percentages of CD56(+) NK-T cells (CD56(+)CD16(-)CD3(+)CD8(-), 2 mo, 6 mo) were lower in FN than F.
4609 15496603 Percentages of M/E cytotoxic/suppressor, Th2, and CD56(+)CD16(-) NK cells in FN were significantly higher than F but were not different from HMF, whereas F was significantly lower than HMF.
4610 15523692 Unmasking immunosurveillance against a syngeneic colon cancer by elimination of CD4+ NKT regulatory cells and IL-13.
4611 15523692 Here, we investigated whether hidden spontaneous antitumor immunosurveillance, in the absence of a vaccine, could be revealed by disruption of this negative regulatory pathway involving CD4+ NKT cells and interleukin-13 (IL-13), in a murine pulmonary metastasis model of a nontransfected, nonregressor, syngeneic tumor, the CT26 colon carcinoma.
4612 15523692 CD1-knock out (CD1-KO) mice, which have conventional CD4+ T cells and CD4+CD25+ regulatory T cells but lack CD1-restricted CD4+ NKT cells, were significantly resistant to lung metastasis of CT26.
4613 15523692 CD8+ T cells were found to act as effectors in antitumor immune responses, since the inhibition of lung metastases observed in naive CD1-KO or CD4+ T cell-depleted mice was abrogated by depletion of CD8+ T cells.
4614 15523692 Lung metastases were significantly decreased by treatment of mice with an IL-13 inhibitor, but not by deficiency or inhibition of IL-4.
4615 15523692 Thus, even for a nonregressor tumor, immunosurveillance exists but is negatively regulated via CD4+ NKT cells possibly mediated by IL-13, and can be unmasked by removal of these negative regulatory components.
4616 15530685 Significant increases in mRNA and protein production of T-helper 1 (Th1) cytokines (IL-2, IFNgamma), mRNA production of a cytotoxic-effector molecule (perforin), and lymphoproliferation response were observed in peripheral blood mononuclear cells (PBMC) from dual-subtype FIV-vaccinated cats after in vitro stimulation with inactivated FIV.
4617 15530685 In contrast, no statistically significant increase in FIV-stimulated mRNA production of Th2 cytokines (IL-4, IL-6) or other cytotoxic-effector molecules (TNFalpha, FasL) was observed in the PBMC from dual-subtype vaccinated cats.
4618 15530685 Moreover, no FIV-specific increases in the IFNgamma, IL-2, and perforin mRNA productions and in the IFNgamma bioactivity and lymphoproliferation responses were observed in the PBMC from cell-immunized cats.
4619 15530685 These observations suggest that IFNgamma induction, lymphoproliferation, and significant portion of IL-2 and perforin productions in the PBMC from dual-subtype vaccinated cats are clearly specific for viral antigens.
4620 15530685 Overall, dual-subtype FIV vaccine elicited strong Th1 response (IFN(, IL-2), which may contribute to the vaccine protection by enhancing the perforin-mediated cytotoxic-cell activity against FIV.
4621 15531037 We examined the immune response of outbred domestic rabbits to the individual myxoma virus antigens M055R, M073R, M115L and M121R, delivered as DNA vaccines co-expressing rabbit interleukin-2 or interleukin-4.
4622 15531040 MVA recombinants induced cytokine responses biased towards IFNgamma and IL-12, while FI-RSV induced strong IL-4/5 responses in the lungs during RSV challenge.
4623 15541044 Elicitation of both CD4 and CD8 T-cell-mediated specific immune responses to HCA587 protein by autologous dendritic cells.
4624 15541044 Enzyme-linked immunospot analysis for interferon-gamma (IFN-gamma) secretion demonstrated HCA587-specific CD8(+) T cells in the antigen-stimulated peripheral blood lymphocytes, and the analysis of CD4(+) T cells by proliferation assay also showed antigen-specific reactivities in normal donors.
4625 15541044 Two-colour flow cytometric analysis of surface markers and intracellular cytokine expression demonstrated that HCA587-specific cytotoxic T lymphocytes exhibited a heterogeneous CD8(+)/CD56(+) expression, and a striking T-helper 1 cytokine bias (IFN-gamma(high)/IL-4(low)) was observed for both CD4(+) and CD8(+) HCA587-specific lymphocyte populations.
4626 15541044 We conclude that HCA587 is a potent immunogen that can induce CD4(+) and CD8(+) T-cell-mediated specific immune responses, and these findings propose HCA587 as a good candidate for the development of a therapeutic protein-based DC tumour vaccine for the treatment of HCC patients.
4627 15548712 Anti-CD137 polarized the cytokine release of VPLNs and spleen cells in response to tumor antigen toward a type 1 (interferon-gamma) versus a type 2 (interleukin-4) profile.
4628 15548712 Cell depletion and the use of knockout animals identified that CD8(+), CD4(+), and NK cells were involved in the tumor rejection response and that CD8(+) cells had the major effector role.
4629 15548712 Polarization toward type 1 (interferon-gamma) versus type 2 (interleukin-4) was also observed with the OT-1 cells from VPLNs and spleen cells after anti-CD137 injections.
4630 15548712 Anti-CD137 polarized the cytokine release of VPLNs and spleen cells in response to tumor antigen toward a type 1 (interferon-gamma) versus a type 2 (interleukin-4) profile.
4631 15548712 Cell depletion and the use of knockout animals identified that CD8(+), CD4(+), and NK cells were involved in the tumor rejection response and that CD8(+) cells had the major effector role.
4632 15548712 Polarization toward type 1 (interferon-gamma) versus type 2 (interleukin-4) was also observed with the OT-1 cells from VPLNs and spleen cells after anti-CD137 injections.
4633 15553669 Monocytes were separated from the peripheral blood collected by leukapheresis, and were cultured with GM-CSF and IL-4 for 6 days.
4634 15553669 Then, TNF-alpha, IL-1beta, IL-6 and PGE2 were added for maturation of DC.
4635 15553669 Th1/Th2 and Tc1/Tc2 balances improved in six of the nine patients after vaccination.
4636 15553669 In this study, it was shown that immunosuppressive factors, such as IAP and TGF-beta, and Th1 balance are useful as markers of immunomonitoring for tumor-DC fusion vaccine in patients with advanced or recurrent gastrointestinal patients.
4637 15557179 Macaques given nasal gp120 with either mCT E112K or nCT showed elevated gp120-specific IgG and IgA Ab responses with virus-neutralizing activity in both their plasma and mucosal external secretions, as well as higher numbers of gp120-specific IgA Ab-forming cells in their mucosal and peripheral lymphoid tissues and of IL-4-producing Th2-type CD4-positive (CD4(+)) T cells than did controls.
4638 15574787 In contrast with the NKT cell agonist alpha-galactosylceramide, which induces both IFN-gamma and IL-4 production by NKT cells, CpG-liposome only induced IFN-gamma production by NKT cells.
4639 15574787 In addition to TLR9, at least two other factors, IL-12 production by DCs and direct contact between DCs and NK or NKT cells, were essential for inducing type 1 innate immunity by CpG-liposome.
4640 15582530 Human Peripheral Blood Mononuclear Cells (PBMC) showed higher levels of IFN-gamma than IL-4 when stimulated with peptides containing Th epitopes.
4641 15603887 Moreover, OM delivery of peptides-CpG2007 induced local IFN-gamma and IL-2 responses and low IL-4 production, demonstrating the polarization towards a Th1 response.
4642 15603899 Responses to gp120pDNA switched to a Th1-type in IL-10-defective mice and to exclusively IgG2a antibodies in IL-4-defective mice.
4643 15603899 Plasmid DNA stimulated IL-10 and IL-12 production by macrophages and dendritic cells (DCs) in vitro and anti-IL-10 antibodies enhanced IL-12 production and DC maturation in response to gp120pDNA.
4644 15604017 Monocytes were differentiated with GM-CSF and interleukin-4 into a viable, non-apoptotic population of immature dendritic cells.
4645 15606613 Low IL-10 responses were evident but IL-4 was not detected.
4646 15607548 SRL172, non-specific immunological adjuvant downregulates interleukin-4, upregulates interleukin-2 production, switching towards a T-helper-1 response, induces an increase in natural killer cells and activates antigen presenting cells.

4650 15621303 Generation of dendritic cells from rabbit bone marrow mononuclear cell cultures supplemented with hGM-CSF and hIL-4.
4651 15621303 Here we show that DCs can be generated in vitro from rabbit bone marrow mononuclear cells (BMMCs) cultured in the presence of the human cytokines GM-CSF and IL-4 and matured with lipopolysaccharide (LPS).
4652 15621303 These cells show upregulation of MHC class II and CD86, as well as downregulation of CD14, do not have non-specific esterase activity, are able to perform receptor-mediated endocytosis, and are potent stimulators of allogeneic T cell proliferation in mixed lymphocyte reactions.

4656 15626469 A panel of three CpG-oligodeoxynucleotides (ODN) and three eukaryotic expression vectors currently used in experimental DNA vaccines in pigs (pcDNA1, pcDNA3.1 and pCI) were screened for their immunostimulatory activity on porcine PBMC by evaluating in vitro the lymphocyte proliferative responses and cytokine profiles (IL-1alpha, IL-2, IL-4, IL-6, IL-10, IFN-gamma, TGF-beta, TNF-alpha).
4657 15626469 Furthermore, CpG-ODN A significantly induced IL-6 and TNF-alpha together with elevated levels of IFN-gamma and IL-2 mRNA expression even though considerable heterogeneity was observed in the response of individual pigs.
4658 15626469 For pcDNA1, proliferation was absent together with significantly decreased levels of IL-6 and IFN-gamma.
4659 15654965 TT-coupled mimotopes induced T helper (Th)1 (interleukin (IL)-2, interferon-gamma) and Th2 (IL-4, IL-5) cytokines, whereas uncoupled mimotopes induced a Th1-biased T cell response.
4660 15661380 In addition, spleen cells from S. mansoni infected mice were found to produce significantly less IFN-gamma and nitric oxide when stimulated in vitro with PPD and several fold higher soluble egg antigen (SEA) and Concanavalin A induced IL-4 and IL-5 secretion.
4661 15664925 Invariant Valpha14 chain NKT cells promote Plasmodium berghei circumsporozoite protein-specific gamma interferon- and tumor necrosis factor alpha-producing CD8+ T cells in the liver after poxvirus vaccination of mice.
4662 15664925 Most studies in mice have focused on splenic and peripheral blood T cells and identified gamma interferon (IFN-gamma)-producing CD8+ T cells as correlates of protection, which can be induced by prime-boost vaccination with recombinant poxviruses.
4663 15664925 We show that intradermal vaccination with recombinant poxviruses activated Valpha14iNKT cells and NK cells in the livers of BALB/c mice while inducing IFN-gamma- and tumor necrosis factor alpha (TNF-alpha)-producing pre-erythrocytic stage antigen-specific CD8+ T cells.
4664 15664925 Greater numbers of hepatic Valpha14iNKT cells secreted interleukin-4 than IFN-gamma.
4665 15664925 Vaccinated Valpha14iNKT-cell-deficient mice had lower, but still protective levels of hepatic and splenic IFN-gamma+ and TNF-alpha+ CD8+ T cells and better protection rates later after challenge with Plasmodium berghei sporozoites.
4666 15664925 Furthermore, double-positive INF-gamma+/TNF-alpha+ CD8+ T cells were enriched in protected livers, suggesting that cells expressing both of these cytokines may be most relevant for protection.
4667 15671528 Interestingly, allogeneic DC-cancer fusion cells were superior in that they efficiently induced Th1-type cytokines but not the Th2-type cytokines interleukin (IL)-10 and IL-4, whereas syngeneic DC-cancer fusion cells were powerful inducers of both Th1 and Th2 cytokines.
4668 15681158 All three formulations induced various degrees of Th1 bias response with prominent production of IFN-gamma being 10-50 times higher than that of IL-4 and IL-5.

4671 15683451 The lymph node homing chemokine receptor CCR-7 expression was induced by TNF-alpha + IL-1beta + IL-6 + prostaglandin E2 but was not induced by Poly I:C + TNF-alpha.
4672 15683451 In general, DC from patients had an intermediate maturity phenotype with a significantly higher expression of CD40 and CD54 compared with healthy donors.
4673 15688366 To determine the mechanism of the anti-tumor effect, intrasplenic lymphocyte populations were analyzed by FACS for NKT, CD4+ and CD8+ lymphocyte subpopulations; STAT 1, 4 and 6 expression in splenocytes was assessed by Western blot, and serum cytokine levels were measured by ELISA.
4674 15688366 NKT/CD4 and CD8/CD4 ratios were significantly increased in groups A and E (12.3 and 17.6 in groups A and D, respectively, compared to 6.4, 4.8 and 5.6 in groups B, C and D, respectively, for the NKT/CD4 ratio; 41 and 19.8 in groups A and E, respectively, compared to 6.5, 11.8 and 3.2 in groups B, C, and D, respectively, for the CD8/CD4 ratio).
4675 15688366 Serum IFNgamma, IL12 and IL4 levels were increased in groups A and E.
4676 15688366 NKT-mediated anti-tumor activity was associated increased NKT and CD8+ T lymphocyte numbers, increased expression of STAT4, a marker for IL-12 activity and elevated serum levels of the proinflammatory cytokines IFNgamma and IL12, and of IL4.
4677 15693140 Dendritic cells derived from metastatic cancer patients vaccinated with allogeneic dendritic cell-autologous tumor cell hybrids express more CD86 and induce higher levels of interferon-gamma in mixed lymphocyte reactions.
4678 15693140 Mononuclear cells were isolated from patients' peripheral blood by density gradient centrifugation, and adherent cells were cultured in medium containing GM-CSF plus IL-4 and, after 5 days, TNF-alpha.
4679 15693140 After 2 more days, Mo-DCs were harvested and their CD80, CD86, and CD83 expression was assessed by flow cytometry.
4680 15693140 They were also used as stimulators in mixed lymphocyte reactions (MLR), where IFN-gamma production was measured by ELISA.
4681 15693140 Mo-DCs from unvaccinated patients expressed significantly lower levels of CD86, and tended to express lower levels of CD83 than Mo-DCs from healthy donors.
4682 15693140 However, Mo-DCs generated after hybrid cell vaccination presented increased expression of the same markers and induced significantly higher levels of IFN-gamma in MLR.

4703 15699483 LFA-1 co-stimulation inhibits T(h)2 differentiation by down-modulating IL-4 responsiveness.
4704 15699483 Specifically, CD28 co-stimulation promotes T(h)2 differentiation, whereas leukocyte function-associated antigen-1 (LFA-1) co-stimulation promotes T(h)1 differentiation and inhibits T(h)2 differentiation.
4705 15699483 We show that co-stimulation through LFA-1 does not decrease early IL-4 secretion, but rather induces a loss in IL-4 responsiveness.
4706 15699483 T cells primed in the context of LFA-1 co-stimulation require a 5-fold increase in the concentration of IL-4 required to drive T(h)2 differentiation, which is not mediated by a loss in IL-4R expression.
4707 15699483 To determine whether LFA-1 co-stimulation impacts on proximal signaling from the IL-4R, we first identified a kinetic window where we could separate IL-4-driven T(h)2 differentiation from initial T cell priming.
4708 15699483 Proximal IL-4R signaling, as evidenced by tyrosine phosphorylation of signal transducer and activator of transcription-6 (STAT6), was not inhibited by initial co-stimulation through LFA-1, yet these T cells still required higher amounts of IL-4 and corresponding higher levels of STAT6 activation to up-regulate GATA-3 and induce T(h)2 differentiation.
4709 15699483 Thus, LFA-1 co-stimulation appears to interfere with GATA-3 expression downstream of STAT6.
4710 15699483 These results suggest that LFA-1 co-stimulation functions as a threshold modulator of T(h)2 differentiation, increasing the effective concentration of IL-4 required to drive T(h)2 responses.

4751 15710900 Lactobacillus-exposed MDCs up-regulated HLA-DR, CD83, CD40, CD80, and CD86 and secreted high levels of IL-12 and IL-18, but not IL-10.
4752 15710900 IL-12 was sustained in MDCs exposed to all three Lactobacillus species in the presence of LPS from Escherichia coli, whereas LPS-induced IL-10 was greatly inhibited.
4753 15710900 MDCs activated with lactobacilli clearly skewed CD4(+) and CD8(+) T cells to T helper 1 and Tc1 polarization, as evidenced by secretion of IFN-gamma, but not IL-4 or IL-13.
4754 15710912 Instead, we found that C3d suppressed the protective immunity against Plasmodium berghei malaria infection and deviated immunity, most notably by suppressing the induction of antibodies specific for the CSP C-terminal flanking sequence and by suppressing the induction of CSP-specific IL-4-producing spleen cells.
4755 15712014 To understand the genetic factors that influence variation in IFN-gamma and IL-4 responses following measles immunization and to provide insight into the factors influencing both cellular and humoral immunity to measles, we assessed associations between human leukocyte antigen (HLA) class II genes and measles-specific Th1 and Th2-type cytokine responses in peripheral blood lymphocytes from 339 children previously vaccinated with two doses of measles-mumps-rubella vaccine (MMR-II).
4756 15712014 Median values for measles-specific IFN-gamma and IL-4 secretion levels were 40.73 and 9.71 pg/ml, respectively.
4757 15712014 The global tests suggested associations between measles-specific IFN-gamma response and alleles of the DRB1 and DQB1 loci (P=0.07 and P=0.02, respectively).

4774 15712014 Median values for measles-specific IFN-gamma and IL-4 secretion levels were 40.73 and 9.71 pg/ml, respectively.
4775 15712014 The global tests suggested associations between measles-specific IFN-gamma response and alleles of the DRB1 and DQB1 loci (P=0.07 and P=0.02, respectively).
4776 15712014 Th1 cytokine responses and DQB1 allele associations revealed that the alleles with the strongest association with IFN-gamma secretion were DQB1*0201, *0303, *0402, and *0602.
4777 15712014 In addition, DPB1*0101, *0201, and *0601 alleles provided suggestive evidence of an HLA association with measles-induced IFN-gamma response, while DPB1*0501 was associated with an IL-4 response.
4778 15712014 These data suggest that IFN-gamma and IL-4 cytokine responses to measles may be genetically restricted in part by HLA class II genes, which in turn can restrict the cellular immune response to measles vaccine.
4779 15713517 The CD14+ cells were placed in culture in the presence of granulocyte macrophage colony stimulating factor (GMCSF) and Interleukin 4 (IL-4).
4780 15714585 Many more Fas ligand-expressing and apoptotic cells were present after peptide immunization than after whole-protein immunization.
4781 15714585 Localization of IL-4-, IL-2- and IFN-gamma-producing cells to the lymphocyte-containing splenic white pulp was only observed with whole-protein immunization.
4782 15720438 A soluble LAG-3 (CD223) molecule (sLAG-3) is a natural, high-affinity ligand for MHC class II.
4783 15720438 It is known to induce maturation of monocyte-derived dendritic cells in vitro and is used as a vaccine adjuvant to induce CD4 T helper type 1 responses and CD8 T-cell responses in vivo.
4784 15720438 Here, we demonstrate that sLAG-3 (but not an MHC class II-specific monoclonal antibody) reduces the differentiation of monocytes into macrophages in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) as well as their differentiation into dendritic cells in the presence of GM-CSF and interleukin-4, as shown by a decrease in CD14 and CD1a expression, respectively.

4816 15745223 Regarding the IFN-gamma production, OMP and IMP induced a high response at 120 h.
4817 15745223 Subcellular fractions of Brucella ovis distinctively induce the production of interleukin-2, interleukin-4, and interferon-gamma in mice.

4820 15748813 However, cytokine analysis demonstrated a mixed pulmonary cytokine response (increases in IL-4, and MCP-1) with no induction of IFN-gamma.
4821 15755506 Compared with pR (encoding the extracellular region of M-CSFR(J6-1)), pF was more effective in inducing humoral and cytotoxic immune response, prolonging survival of mice challenged with SP2/0-CSFR(J6-1) tumor cells, and inducing IFN-gamma and IL-4 release by splenocytes.
4822 15773403 As revealed in this study, neutrophilokines regulate the synthesis of IL-2 by T helpers of type 1, IL-4 and IL-5 by T helpers of type 2, IL-1 by B lymphocytes, as well as the expression of receptors IL-2 by immunocompetent cells.
4823 15780449 The serum levels of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) were increased, while no significant increase was observed in interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10) or tumor necrosis factor-alpha (TNF-alpha).
4824 15780483 (1) Helminths evade or suppress host immune responses, by producing anti-inflammatory and other immunomodulatory molecules. (2) Helminths induce chronic Th2 activation, which can modify cytokine profiles and immunological responses to heat shock proteins, Chlamydia pneumoniae and cytomegalovirus. (3) The chronic Th2 profile may modulate monocyte activation and chemotaxis to inflammatory sites (atherosclerotic plaques). (4) Chronic Th2 activation may lead to a cytokine profile that could be beneficial for attenuation of atherosclerosis development (upregulation of IL-4, IL-10 and IL-13 and downregulation of proinflammatory cytokines). (5) Helminthic infections may reduce plasma LDL level not only by affecting the host nutrition, but also via modulation of naturally occurring antibodies to cholesterol.
4825 15781125 Interestingly, ECTV-IL-4-mediated immune suppression was not accompanied by a reduction in systemic IFN-gamma expression, suggestive of an alternative or highly localized suppressive mechanism.
4826 15787742 Murine bone marrow-derived dendritic cells (DC) can be generated by culture in the presence of granulocyte/macrophage colony-stimulating factor (GM-CSF) alone or GM-CSF in conjunction with interleukin-4 (IL-4).
4827 15787742 Also, the four culture conditions generated CD11c+ DC with comparable levels of major histocompatibility complex (MHC) class II, CD40, CD80 and CD86 expression, with the exception of cells cultured under serum-free conditions in the absence of IL-4, which displayed suboptimal levels of these markers.
4828 15787742 However, both DC populations displayed a similar capacity to take up fluorescein isothiocyanate (FITC)-albumin by macropinocytosis and FITC-Dextran by the mannose receptor and to secrete IL-12 in response to stimulation with lipopolysaccharide (LPS) or an agonistic anti-CD40 monoclonal antibody.
4829 15787742 Therefore, we conclude that although both DC culture methods result in the production of DC with similar functional abilities, under serum-free conditions, DC cultured in GM-CSF and IL-4 show an increased stimulatory potential over DC cultured in GM-CSF alone.

4848 15806292 Our preliminary study on the transcription levels of IFN-gamma and IL-4 in splenic CD4+ T cells revealed that attenuated cercariae elicited predominantly a Th1 response in mice at the early stage, whereas normal cercariae stimulated primarily Th2-dependent responses.
4849 15806292 However, for IL-12 and IL-4, the potent inducers of Th1 and Th2 responses, respectively, as well as IL-10, there were no differences over the course of the experiment between the infected and vaccinated mice.

4853 15807859 Depletion of CD4 cells prior to culture and MV stimulation completely abrogated both IFN-gamma and IL-4 production, whereas depletion of CD8 cells did not diminish production, suggesting that CD4+CD8- T cells were principally involved in production of these cytokines.

4861 15814696 Interestingly, we found that IgG4 production in the coculture correlated with the TCC production of IL-10 (r2 = 0.352, p = 0.0001), but not with IL-2, IL-4, nor IFN-gamma.
4862 15817260 CD8+-dependent CNS demyelination following ocular infection of mice with a recombinant HSV-1 expressing murine IL-2.
4863 15817260 In contrast, mice infected with HSV-IFN-gamma or HSV-IL-4, which are identical to HSV-IL-2 but express IFN-gamma or IL-4 instead of IL-2, did not exhibit demyelination.

4883 15845642 Mycobacterium bovis Bacillus Calmette-Guerin infects DC-SIGN- dendritic cell and causes the inhibition of IL-12 and the enhancement of IL-10 production.
4884 15845642 Recent studies have shown that BCG and Mtb target the DC-specific C-type lectin intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) to infect DC and inhibit their immunostimulatory function.
4885 15845642 This would occur through the interaction of the mycobacterial mannosylated lipoarabinomannan to DC-SIGN, which would prevent DC maturation and induce the immunosuppressive cytokine interleukin (IL)-10 synthesis.
4886 15845642 Here, we confirm that DC-SIGN is expressed in DC derived from monocytes cultured in granulocyte macrophage-colony stimulating factor (GM-CSF) and IL-4 and show that it is not expressed in DC derived from monocytes cultured in GM-CSF and interferon-alpha (IFN-alpha).
4887 15845642 We also demonstrate that DC-SIGN(-) DC cultured in GM-CSF and IFN-alpha are able to phagocytose BCG and to undergo a maturation program as well as DC-SIGN(+) DC cultured in IL-4 and GM-CSF.
4888 15845642 We also show that BCG causes the impairment of IL-12 and the induction of IL-10 secretion by DC, irrespective of DC-SIGN expression.

4899 15877606 Monocyte-derived dendritic cells (mDC), the most frequently applied DC subset in clinical studies, which can be obtained easily from peripheral blood monocytes after incubation with GM-CSF and IL-4, have not been clearly demonstrated to be activated by CpG oligodeoxynucleotides (ODN).
4900 15877606 However, we did not observe increased expression of maturation-associated and functionally relevant surface antigens (CD14, HLA-DR, CD40, CD83, CD80 and CD86), significant secretion of IL-12 and IFN-alpha in culture supernatant, or enhanced antitumour activation of cytokine-induced killer cells.
4901 15879106 CpG-independent synergistic induction of beta-chemokines and a dendritic cell phenotype by orthophosphorothioate oligodeoxynucleotides and granulocyte-macrophage colony-stimulating factor in elutriated human primary monocytes.
4902 15879106 High levels of the Th1-attracting, HIV-1-inhibitory chemokines, CCL3/MIP-1alpha and CCL4/MIP-1beta, were induced in human primary monocytes when CpG- or non-CpG-ODN was combined with GM-CSF, but not with IL-4 or IFN-gamma.
4903 15879106 Cells treated with non-CpG PS-ODN and GM-CSF expressed dendritic cell marker CD83 and high levels of HLA-DR and costimulatory molecules, and were CD14(-) or CD14(dim), consistent with monocyte differentiation into a dendritic cell phenotype.
4904 15879106 Secreted CCL3 and CCL4 were detected as a heterodimer.
4905 15885128 Analysis of the cytokine profiles of draining lymph nodes or lymph-node-derived mononuclear cells from different groups by real-time reverse transcription-polymerase chain reaction revealed that, while gene-gun-bombardment induced a Th2-type cytokine microenvironment with increased interleukin-4 (IL-4) and IL-10 mRNA expression and almost no increase in IL-12 and interferon-gamma mRNA expression in draining lymph nodes, intradermal injection as well as subcutaneous injection of muscle induced the opposite.
4906 15890793 Enhanced leukocyte infiltration may be driven by increased levels of the type 1 cytokines, IL-2 and IFN-gamma, and TNF-alpha, observed at the site of antigen reexposure in animals that had been stressed at the time of primary immunization.
4907 15890793 In contrast, no differences were observed in type 2 cytokines, IL-4 or IL-5.
4908 15894487 It was observed that the levels of IFN-gamma and IL-2 production rather than IL-4 and IL-6 were increased as the disease became more severe.
4909 15894487 On comparison, the subsequent values of IL-6, IFN-gamma, IL-4 and IL-2 were found to be less significant in healthy primed T-cell cultures.
4910 15894487 It was observed that the levels of IFN-gamma and IL-2 production rather than IL-4 and IL-6 were increased as the disease became more severe.
4911 15894487 On comparison, the subsequent values of IL-6, IFN-gamma, IL-4 and IL-2 were found to be less significant in healthy primed T-cell cultures.
4912 15905560 Kinetoplastid membrane protein-11 DNA vaccination induces complete protection against both pentavalent antimonial-sensitive and -resistant strains of Leishmania donovani that correlates with inducible nitric oxide synthase activity and IL-4 generation: evidence for mixed Th1- and Th2-like responses in visceral leishmaniasis.
4913 15905560 KMP-11 DNA vaccinated hamsters were protected by a surge in IFN-gamma, TNF-alpha, and IL-12 levels along with extreme down-regulation of IL-10.
4914 15905564 IL-12/23 p40(-/-) and IFN-gamma(-/-) mice, which were able to reject the initial inoculation of IL-4 expressing tumors, failed to mount a sustained systemic response against parental (nontransfected) tumor cells.
4915 15905564 Adoptive transfer of TIDCs isolated from vaccinated wild-type, but not IL-12/23 p40(-/-), mice were capable of promoting tumor-specific CTL responses in syngeneic recipient animals.
4916 15905564 Interestingly, both STAT4(-/-) and STAT6(-/-) mice failed to reject IL-4-transfected tumors in concert with the reduced capacity of TIDCs to produce IL-12p70 and to promote specific antitumor CTL reactivity.
4917 15905564 IL-12/23 p40(-/-) and IFN-gamma(-/-) mice, which were able to reject the initial inoculation of IL-4 expressing tumors, failed to mount a sustained systemic response against parental (nontransfected) tumor cells.
4918 15905564 Adoptive transfer of TIDCs isolated from vaccinated wild-type, but not IL-12/23 p40(-/-), mice were capable of promoting tumor-specific CTL responses in syngeneic recipient animals.
4919 15905564 Interestingly, both STAT4(-/-) and STAT6(-/-) mice failed to reject IL-4-transfected tumors in concert with the reduced capacity of TIDCs to produce IL-12p70 and to promote specific antitumor CTL reactivity.
4920 15908354 In vitro stimulation of splenocytes from the vaccinated mice with either recombinant Cu,Zn SOD (rSOD) or crude Brucella protein resulted in a T-cell proliferative response and the induction of gamma interferon secretion but not interleukin-4.
4921 15919138 However, it was not known if B7-1/Ig acted only by binding CD28 (amplifying a stimulatory signal) or by blocking CTLA-4 on T cells (removing inhibitory signals).
4922 15919138 Here, we aimed to determine this using a plasmid encoding mutant B7-1/Ig (B7-1wa/Ig), which binds only to CTLA-4 but not to CD28.
4923 15919138 We found that, in vitro, a significant fraction of CD3/CD28-activated T cells (in the absence of DCs) expressed CTLA-4 and B7-1.
4924 15919138 Primed T cells of CTLA-4(+)B7-1(+/-) phenotype acted as regulatory T cells by inhibiting IFNgamma production by re-stimulated CTLA-4(-)B7-1(-) cells, and this was reversed by antibodies against IL-10 or TGF-beta1.
4925 15919138 Both B7-1wa/Ig and CTLA-4/Ig, which bind to CTLA-4 and B7-1/B7-2 respectively, enhanced IFNgamma production, but not the proliferation or IL-4 release in mixed T-cell populations containing these two cell types.
4926 15919138 In contrast, CTLA-4(-)B7-1(-) T cells produced IFNgamma which was not affected by B7-1wa/Ig or CTLA-4/Ig.
4927 15927322 Both IgG1 and IgG2a hMPV-specific antibodies were found in sera, while interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) were found in bronchoalveolar lavage.
4928 15944302 Whereas RA reduced type 1 cytokines (IFN-gamma and IL-12), PIC enhanced both type 1 and type 2 cytokines (IL-4 and IL-12) and cytokine-related transcription factors.
4929 15944302 Despite the presence of PIC, the IL-4:IFN-gamma ratio was significantly elevated by RA.
4930 15944302 In addition, RA and/or PIC modulated NK/NKT cell populations and the level of expression of the costimulatory molecules CD80/CD86, evident 3 days after priming.
4931 15944302 Notably, the NKT:NK and CD80:CD86 ratios were correlated with the IL-4:IFN-gamma ratio, indicative of multiple converging modes of regulation.

4939 15944302 Notably, the NKT:NK and CD80:CD86 ratios were correlated with the IL-4:IFN-gamma ratio, indicative of multiple converging modes of regulation.
4940 15944732 In mice vaccinated and supplemented with Imiquimod, a small but significant increase of rat p185neu-specific cytotoxicity and of IFN-gamma and IL-2-producing CD8T cells, together with a reduction of IL-4-producing CD4T cells, and a switch from an IgG1 towards a IgG2a phenotype of anti-p185neu antibodies, suggested a TH1 polarization of the immune response.
4941 15946922 Accordingly, in spleen cell supernatants the Th1-associated cytokine IFN-gamma was increased, and the Th2-associated cytokine IL-4 was downregulated.
4942 15947427 In presence of anti-CD3, the 57 kDa antigen was found to increase the level of IL-2 significantly instead of IL-4.
4943 15947427 Furthermore, the protein tyrosine kinase was activated during anti-CD3 stimulation, which up-regulated the phosphatidylinositol kinase of p85-mediated serine kinase protein kinase-C of p70.
4944 15958066 It induced lower but progressive production of interferon (IFN)-gamma, interleukin (IL)-4 and tumour necrosis factor (TNF)-alpha.
4945 15958067 Enhanced clearance of Candida albicans correlated with both early mRNA gene expression for interleukin (IL)-4 and interferon (IFN)-gamma and expression of their secreted products in cultures of cervical lymph nodes stimulated with Candida antigen.
4946 15958067 Delayed clearance, less pronounced levels of the cytokine response, saliva IFN-gamma and nitric oxide, and later mRNA expression for IL-4 and IFN-gamma relative to feeding with the L. acidophilus isolate were noted in mice fed a different Lactobacillus isolate (L. fermentum).
4947 15958067 Enhanced clearance of Candida albicans correlated with both early mRNA gene expression for interleukin (IL)-4 and interferon (IFN)-gamma and expression of their secreted products in cultures of cervical lymph nodes stimulated with Candida antigen.
4948 15958067 Delayed clearance, less pronounced levels of the cytokine response, saliva IFN-gamma and nitric oxide, and later mRNA expression for IL-4 and IFN-gamma relative to feeding with the L. acidophilus isolate were noted in mice fed a different Lactobacillus isolate (L. fermentum).
4949 15961574 To identify DCs with differing abilities to direct Th1/Th2 cell differentiation, we cultured mouse bone marrow progenitors in granulocyte macrophage-colony stimulating factor (GM), GM + interleukin (IL)-4, or GM + IL-15 and generated three distinct DC populations.

4967 15972497 Our results showed that StxB1 and mStx1, but not native Stx1 (nStx1), resulted in enhanced expression of CD86, CD40, and major histocompatibility complex (MHC) class II molecules and, to some extent, also enhanced the expression of CD80 on bone marrow-derived DCs.
4968 15972497 StxB1-treated DCs exhibited an increase in tumor necrosis factor alpha and interleukin-12 (IL-12) production, a stimulation of DO11.10 T-cell proliferation, and the production of both Th1 and Th2 cytokines, including gamma interferon (IFN-gamma), IL-4, IL-5, IL-6, and IL-10.
4969 15972497 When mice were given StxB1 subcutaneously, the levels of CD80, CD86, and CD40, as well as MHC class II expression by splenic DCs, were enhanced.

4975 15985227 Vaccination via intranasal and subcutaneous routes triggered immune activation in the spleen and cervical lymph node, while the former route of vaccination lead to higher antigen-specific lymphocyte proliferation, interferon-gamma, interleukin-12 and interleukin-4 responses in cervical lymph node and induction of antigen-specific IgA responses at mucosal level of the respiratory tract.
4976 15989657 Other factors may, however, influence responses in vivo, including host genetic make-up, microbial load and the induction of antagonistic cytokine pathways, notably IL-4 and IL-10.
4977 16000953 A homologous series of Ii-Key/gp100(46-58) hybrids was synthesized to test the influence of spacer length (between Ii-Key and the gp100(48-58) epitope) on in vivo enhancement of gp100(48-58)-specific CD4+ T-lymphocyte responses.
4978 16000953 As measured by IFN-gamma and IL-4 ELISPOT cytokine assays, the most effective vaccine hybrid was the one with a shorter linker between Ii-Key and the epitope.
4979 16000958 In this study six patients with hormone-refractory prostate cancer were monitored for their ability to mount PSA-specific cellular responses after receiving a pVAX/PSA DNA vaccine (patients 1-3, 100 microg; patients 7-9, 900 microg) with recombinant GM-CSF and IL-2 as adjuvants.
4980 16000958 IFNgamma ELISPOT showed that naturally processed PSA protein and PSA peptides are recognized by T cells in the blood of some prostate cancer patients after a PSA DNA vaccine.
4981 16000958 Analysis of other cytokines showed the production of IL-4 and IL-6 but importantly did not show an increase in the number of IL-10-producing cells after vaccination in any of the patients.
4982 16002678 Treatment of naive mice with the COX-2 inhibitor, SC-58236, skewed splenocytes toward a type 1 cytokine response, inducing IFN-gamma, IL-12, and IFN-gamma-inducible protein 10, whereas the type 2 cytokines IL-4, IL-5, and IL-10 remained unaltered.
4983 16002678 Studies performed in CD4 and CD8 knockout mice revealed a requirement for the CD4 T lymphocyte subset for the complete rejection of tumors.
4984 16002678 In vivo depletion of IFN-gamma abrogated the COX-2 inhibitor-mediated enhancement of the vaccination effect.
4985 16014914 In the first few days postinfection, RSV/IL-4 was associated with a small but significant acceleration in the expansion of pulmonary T lymphocytes specific for an RSV CD8(+) cytotoxic T-lymphocyte (CTL) epitope presented as a major histocompatibility complex class I tetramer.
4986 16014914 Following a challenge with wt RSV, there was an increase in Th2 cytokines in the animals that had previously been infected with RSV/IL-4 compared to those previously infected with wt RSV, but the CD8(+) CTL response and the amount of pulmonary inflammation were not significantly different.

4990 16037410 Classically, mature monocyte-derived DC are generated in vitro in the presence of interleukin (IL)-4, granulocyte macrophage-colony stimulating factor, and inflammatory cytokines (G4-DC).
4991 16037410 Recently, it has been described that DC can also be generated in the presence of IL-3 and interferon (IFN)-beta and that these DC are efficiently matured using polyriboinosinic polyribocytidylic acid (I3-DC).
4992 16037410 Phenotypic characterization of the DC revealed differences in the expression of the monocyte marker CD14 and the maturation marker CD83.
4993 16037410 Low expression of CD14 and high expression of CD83 characterized G4-DC, whereas I3-DC displayed intermediate expression of CD14 and CD83.
4994 16037410 Upon CD40 ligation, G4-DC produced lower amounts of IFN-alpha and pulmonary and activation-regulated chemokine, similar amounts of IL-6, macrophage-inflammatory protein (MIP)-1alpha, and MIP-1beta, and higher amounts of IL-12 p70, tumor necrosis factor alpha, and MIP-3beta than I3-DC.
4995 16037410 Finally, in vitro stimulations showed that fresh and frozen peptide-loaded I3-DC are more potent inducers of Melan-A-specific CD8(+) T cell responses than G4-DC.
4996 16041007 Mucosal type 2/3 responses (producing interleukin-4 [IL-4], IL-6 and/or transforming growth factor beta) could be necessary for optimal induction of protective secretory immunoglobulin A responses.
4997 16041007 On the other hand, systemic type 1 responses (including gamma interferon [IFN-gamma], tumor necrosis factor alpha, and optimal cytotoxic T-cell responses) are likely to be critical for protection against the disseminated intracellular replication that occurs after mucosal invasion.

5013 16051244 Decreased congenital transmission among immunized mice correlated with a predominately Th2 immune response compared to non-immunized mice as indicated by an increased ratio of interleukin 4 (IL-4) to interferon gamma (IFN-gamma) secretion from antigen-stimulated splenocytes.
5014 16053938 The level of IFN-gamma, IL-4 and TNF-alpha released by spleen lymphocytes stimulated with PPD was detected with ELISA.
5015 16053938 Vaccination with pcD85B induced high level of IFN-gamma and TNF-alpha.
5016 16081596 Anti-CTLA-4 treatment enhanced the antibody production in SCID/SCID mice reconstituted with B lymphocytes and CD4(+) and CD8(+) T lymphocytes but not in SCID/SCID mice reconstituted with B lymphocytes in the absence of CD4(+) and/or CD8(+) cells.
5017 16081596 Administration of anti-CTLA-4 in BALB/c mice but not in nu/nu mice resulted in a markedly increased production of interleukin (IL)-2, IL-4, and interferon-gamma.
5018 16081824 Polarized Th1 vs Th2 responses in Leishmania major-infected mice suggested that a shift in balance from IL-4 to IFN-gamma was the key to vaccine success.
5019 16081824 Both induced low IL-4 and high IFN-gamma prechallenge.
5020 16081824 Strikingly, high prechallenge CD4 T cell-derived IL-10 predicted vaccine failure using LACK, whereas low IL-10 predicted protection with TRYP.
5021 16081824 The ratio of IFN-gamma:IL-10 was thus a clear prechallenge indicator of vaccine success.
5022 16081824 Challenge infection caused further polarization to high IL-10/low IFN-gamma with LACK and low IL-10/high IFN-gamma with TRYP.
5023 16081824 Ex vivo quantitative RT-PCR and in vitro depletion and suppression experiments demonstrated that Ag-driven CD4+ CD25+ T regulatory 1-like cells were the primary source of IL-10 in LACK-vaccinated mice.
5024 16081824 Anti-IL-10R treatment in vivo demonstrated that IL-10 was functional in determining vaccine failure, rendering LACK protective in the presence of high IFN-gamma/low IL-5 responses.

5032 16081851 Mice bearing intracranial GL261 glioma or MCA205 sarcoma received peripheral immunizations with corresponding irradiated tumor cells engineered to express IL-4 or GM-CSFs, respectively, as well as intratumoral delivery of DC-IFN-alpha.
5033 16081851 This regimen prolonged survival of the animals and induced tumor-specific CTLs that expressed TRAIL, which in concert with perforin and Fas ligand (FasL) was involved in the tumor-specific CTL activity of these cells.
5034 16081851 The in vivo antitumor activity associated with this approach was abrogated by administration of neutralizing mAbs against TRAIL or FasL and was not observed in perforin-/-, IFN-gamma-/-, or FasL-/- mice.
5035 16081851 Transduction of the tumor cells with antiapoptotic protein cellular FLIP rendered the gene-modified cells resistant to TRAIL- or FasL-mediated apoptosis and to CTL killing activity in vitro.

5049 16125469 Mice bearing SCCVII/SF cells in the oral cavity were vaccinated subcutaneously with irradiated, rvv-IL-2-infected tumor cells combined with intratumoral injection of rvv-IL-2, resulting in recruitment of larger numbers of CD3+ CD8+ and CD3+ CD4+ T cells in the spleen (Sp) and tumor-draining lymph nodes (TDLN) compared to control vaccine rvv-lacZ.
5050 16125469 Tumor-specific CD8+ T and CD4+ helper T cell activities in the Sp and TDLN were significantly increased in rvv-IL-2-treated mice.
5051 16125469 Sp and TDLN cells from rvv-IL-2-treated mice secreted significantly higher levels of IL-2 and IFN-gamma compared to rvv-lacZ-treated mice, while the levels of IL-4 and IL-5 were comparable.

5097 16169588 The titres of specific antibodies and serum IgG1/IgG2 ratio to PRV vaccine, the proliferation of peripheral blood mononuclear cells (PBMCs), IL-4 and interferon-gamma(IFN-gamma) in piglets serum were examined to identify the immune response of the newborn piglets.
5098 16169588 The results showed that piglets immunized with PRV vaccine and CpG ODN presented high titers of PRV-specific antibodies and IgG2 isotype, a Th1-dominated (IFN-gamma) cytokine profile, together with inducing higher proliferation of PBMCs.
5099 16178761 Other areas include the development of humanised monoclonal antibodies for asthma therapy including those against IgE, IL-4 and IL-5 together with the inhibition of adhesion pathways and/or chemokines responsible for inflammatory cell accumulation in the asthmatic lung.

5158 16272329 Such suppression was also evident upon the Salmonella-CFA/I infection of macrophages resulting in diminished TNF-alpha, IL-1, and IL-6 production and suggesting that the CFA/I fimbrial expression by Salmonella may protect against a proinflammatory disease.
5159 16272329 This protective effect was accompanied by a loss of encephalitogenic IFN-gamma-secreting Th cells and was replaced with an increase in IL-4, IL-10, and IL-13 secretion.
5160 16278080 Tumour necrosis factor alpha (TNF-alpha) was measured in the supernates of cultured cells and both TNF-alpha and interleukin-4 (IL-4) were measured in serum samples.
5161 16278301 The levels of allergen-specific CD4(+) T cell-derived allergy-associated T helper 2 cytokine production of IL-4, IL-5, and IL-13 and histamine release in serum were significantly decreased.
5162 16279537 The generation of ripe dendrite cells (DC) of marrow origin was obtained with the use of the vaccine Immunovac-BN-4, an immunomodulator of microbial origin, as well as Klebsiella pneumoniae LPS and TNF-alpha, as ripening inducers.
5163 16279537 The immunophenotype of cells altered from CD34+, CD38-, CD40-, CD80-, CD86-, MHC I-, MHC II-, F4/80- to CD34-, CD38+, CD40+, CD80+, MHC I+, MHC II+, F4/ 80(low).
5164 16279537 In culture medium with ripe DC the levels of such cytokines as IL-1b, IL-6, IL-12, IFN-gamma, TNF-alpha significantly increased and the production of IL-4 decreased.
5165 16279537 The content of IL-2 and IL-10 remained unchanged.
5166 16283303 Patients were vaccinated either by intradermal injection of PSA-peptide and GM-CSF or by intravenous administration of autologous dendritic cells pulsed with PSA-peptide at weeks 1, 4 and 10.
5167 16283303 The phenotype of recovered T cells demonstrated variable proportions of CD4+CD8-, CD4-CD8+ and CD4+CD8+ T cell populations.
5168 16283303 Cytokine analysis of PSA-peptide stimulated T cells per bead array assay exhibited specific IFN-gamma and TNF-alpha response in six of seven patients.
5169 16283303 Specific IL-4 response was observed in five patients, while IL-10 response was detected in one patient.
5170 16286158 Vaccines containing the ginseng-fraction Rb1 induced serum-detectable amounts of IL-4 and IL-10 as early as 24h after primary injection that was confirmed in sera collected at 24 and 72 h post re-vaccination.
5171 16286158 Five weeks after booster, immune lymphocytes were still producing large amounts of cytokines including IFN-gamma, IL-2, IL-4, IL-10 and TNF-alpha and the antibody titres were still similar to those titres recorded 1 week post booster.

5174 16297162 We examined measles-specific antibodies, lymphoproliferation and the Th1/Th2 signature cytokines, interferon (IFN)-gamma and interleukin (IL)-4, in a population-based cohort of healthy children from Olmsted County, Minnesota after two doses of measles-mumps-rubella-II (MMR-II) vaccine.
5175 16297162 However, a small proportion of subjects demonstrated an immune response skewed towards the Th2 type, characterized by the presence of either IL-4 and/or measles-specific antibodies and a lack of IFN-gamma production.
5176 16297162 Further, we observed a significant positive correlation between lymphoproliferation and secretion of IFN-gamma (r = 0.20, P = 0.0002) and IL-4 (r = 0.15, P = 0.005).
5177 16297162 Further, a positive correlation between lymphoproliferation and IL-4 and IFN-gamma suggests that immunity to measles may be maintained by both Th1 and Th2 cells.

5190 16299302 In addition, spleen cells from rOmp31-immunized mice produced interleukin 2 (IL-2) and gamma interferon, but not IL-10 or IL-4, after in vitro stimulation with rOmp31, suggesting the induction of a T helper 1 (Th1) response.
5191 16299302 In vitro T-cell subset depletion indicated that rOmp31 immunization elicited specific CD4+ T cells that secrete IL-2 and gamma interferon, while CD8+ T cells induced cytotoxic-T-lymphocyte activity.
5192 16299302 In vivo depletion of T-cell subsets showed that the rOmp31-elicited protection against B. melitensis infection is mediated by CD4+ T cells while the contribution of CD8+ T cells may be limited.
5193 16301667 Peptide-induced T cell clones were of the Th0 subset, secreting high levels of IFN-gamma as well as variable levels of Th2-type cytokines (IL-4, IL-6).
5194 16310897 Intramuscular vaccination of foxhounds with a Leishmania multicomponent (10 antigen) DNA vaccine resulted in antigen-induced lymphoproliferative and IFN-gamma (but not IL-4) responses.
5195 16310897 This response was not augmented by co-administration of canine IL-12 or GM-CSF DNA adjuvants.
5196 16313365 A marked increase in FPE was observed in 1 hr interleukin (IL)-4 and granulocyte macrophage-colony stimulating factor (GM-CSF)-stimulated monocytes.
5197 16315029 Immature bone marrow derived DC grown in vitro with IL-4 and GM-CSF were pulsed with B16-CD44.
5198 16315029 After 48 h of pulsing, maturation of DC was demonstrated by production of IL-12 and upregulation of CD80 and CD40 expression.
5199 16315029 To test the efficacy of vaccination with DC+B16-CD44, mice were vaccinated subcutaneously Lymphocytes from mice vaccinated with DC+B16-CD44 produced IFN-gamma in response to B16 melanoma lysates as well as an MHC class I restricted B16 melanoma-associated peptide, indicating B16 specific CD8 T cell activation.
5200 16331510 Immunologic significance of HLA class I genes in measles virus-specific IFN-gamma and IL-4 cytokine immune responses.
5201 16331510 Median values for measles-specific interferon gamma (IFN-gamma) and interleukin-4 (IL-4) cytokines were 40.7 pg/ml [interquartile range (IQR) 8.1-176.7] and 9.7 pg/ml (IQR 2.8-24.3), respectively.
5202 16331510 Class I HLA-A (*0101 and *3101) and HLA-Cw (*0303 and *0501) alleles were significantly associated with measles-virus-induced IFN-gamma secretion.
5203 16331510 HLA-A*3101 and Cw*0303 were associated with a higher median IFN-gamma response, while A*0101 and Cw*0501 were associated with lower measles-specific IFN-gamma response.
5204 16331510 We found limited associations between HLA class I gene polymorphisms and Th2-like (IL-4) immune responses after measles vaccination, indicating that HLA class I molecules may have a limited effect on measles-vaccine-induced IL-4 secretion.
5205 16331510 Immunologic significance of HLA class I genes in measles virus-specific IFN-gamma and IL-4 cytokine immune responses.

5215 16331615 This triple combination therapy elicits a tumor-specific immune response evidenced by elevated IFN-gamma and IL-4 secretion by CD4+ T cells and results in increased infiltration of CD4+ and CD8+ T cells to the tumor site.
5216 16332516 Dendritic cells incubated with irradiated tumor cells effectively stimulate T lymphocyte activation and induce enhanced expression of CD69, CD25 as well as production of IFNgamma and IL4.
5217 16332516 The T lymphocyte activation was assessed by determination of expression of CD25, CD69, and intracellular IFNgamma and IL4 production.
5218 16332516 Activated DC significantly increased the proportion of CD25+ and CD69+ cells as well as IFNgamma+ and IL4+ cells among CD3+ T lymphocytes.

5225 16341143 Interestingly, the modified plasmid vaccine predominantly enhanced the type 2 immune responses manifested by an increased IgG1 to IgG2a antibody ratio and a greater induction of GATA-3 and IL-4 mRNA than that of T-bet and IFN-gamma mRNA in spleen cells from vaccinated mice.
5226 16341143 In addition, protection against tumor challenge in vaccinated mice showed that there was no significant change in mice survival after in vivo CD8+CTL depletion, indicating that antitumor immunity augmented by plasmid encoding GM-CSF and target PDTRP gene vaccine was dominated by Th2 immune response.
5227 16352562 To understand the role of cytokines during rotavirus infection, we assessed the kinetics of tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) (proinflammatory), IL-12 (Th1 inducer), gamma interferon (IFN-gamma) (Th1), IL-4 and IL-10 (Th2), and transforming growth factor beta (Th3) cytokine responses by enzyme-linked immunosorbent assay in serum and intestinal contents of neonatal gnotobiotic pigs and IL-12, IFN-gamma, IL-4, and IL-10 cytokine-secreting cell (CSC) responses of mononuclear cells from ileum, spleen, and blood by ELISPOT.
5228 16352562 In serum, IL-6 was significantly elevated at postinoculation day (PID) 1 in the VirHRV group and at PID 3 in both HRV groups.
5229 16352562 A significantly higher percentage of pigs had IFN-gamma and IL-10 responses in serum after VirHRV infection than after AttHRV infection or in controls.
5230 16352562 Higher protection rates may be associated with more balanced Th1- and Th2-type responses, but induction of higher earlier IFN-gamma (Th1) and proinflammatory cytokines triggered by VirHRV may also play an important role in the higher intestinal immunoglobulin A responses and protection rates induced by VirHRV.
5231 16356602 As a result, IL-4 production in splenocytes and anti-OVA IgG1 level were preferentially elicited by particle bombardment with OVA-loaded PLG MS compared with IFN-gamma and anti-OVA IgG2a level.
5232 16367942 Peripheral blood mononuclear cells were analysed with ELISPOT analysis for number of spontaneous or antigen/mitogen stimulated IFN-gamma, IL-4, IL-10 and IL-12 secreting cells or with ELISA for concentration of spontaneous or antigen/mitogen stimulated IFN-gamma, IL-5 and IL-10.
5233 16367942 Individuals with a history of gangrenous appendicitis demonstrated ability to increased IL-10 and IFN-gamma production.
5234 16367942 The increased IFN-gamma may support the notion of gangrenous appendicitis as an uncontrolled Th1 mediated inflammatory response and increased IL-10 may speculatively indicate the involvement of cytotoxic cells in the progression to perforation.
5235 16367944 Immunization led to significant production of interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha by antigen-stimulated lymphocytes.
5236 16367944 In contrast, no significant induction of interleukin (IL)-4 or IL-10 was observed.
5237 16368992 A Th2 bias in the following cytokine ratios, interleukin-4 (IL-4)/IL-12, IL-5/IL-12, IL-13/IL-12, IL-4/gamma-IFN (IFN-gamma), IL-5/IFN-gamma, and IL-13/IFN-gamma, in response to SWAP predicted a 1.4- to 2.9-month longer time to reinfection (P < 0.05) and a 27 to 55% lower intensity of reinfection (P < 0.05).
5238 16368992 Only a high IL-5/IL-10 ratio in response to Sj22.6 predicted a 3.0-month-longer time to reinfection (P = 0.03).
5239 16386313 We show here that a canine IL-12 DNA, constructed by fusing the p35 and p40 subunit cDNAs with an interspacing linker, generated stable IL-12 transcripts when placed under control of a strong constitutive promoter.
5240 16386313 The protein expressed from this fused cDNA was fully functional in promoting a type 1 (IFN-gamma) and suppressing a type 2 (IL-4) cytokine response following both in vitro transfection of a canine cell line and in vivo delivery to dogs.
5241 16387339 In contrast, N-GST elicited strong T cell IL-4 but minimal IFN-gamma responses and a much greater antibody response.
5242 16387339 The pronounced Th-2 and humoral response to N protein plus adjuvant are in contrast to the balanced IFN-gamma and IL-4 responses and strong memory CTL responses to the LAMP-N chimera.
5243 16387339 In contrast, N-GST elicited strong T cell IL-4 but minimal IFN-gamma responses and a much greater antibody response.
5244 16387339 The pronounced Th-2 and humoral response to N protein plus adjuvant are in contrast to the balanced IFN-gamma and IL-4 responses and strong memory CTL responses to the LAMP-N chimera.

5269 16389614 Moreover, we observed that the production of IL-4 and IL-10 increased in mice vaccinated with hCGbeta-C3d3-DNAs and the ratio of IL-4/IFN-(gamma) showed a Th2 bias of immune response in the mice immunized with hCGbeta-C3d3-DNAs.
5270 16397274 Tumor-derived interleukin-4 reduces tumor clearance and deviates the cytokine and granzyme profile of tumor-induced CD8+ T cells.
5271 16397274 An interleukin (IL)-4-containing tumor environment is reported to be beneficial for immune clearance of tumor cells in vivo; however, the effect of IL-4 on the effector CD8+ T cells contributing to tumor clearance is not well defined.
5272 16397274 We have used the immunogenic HLA-CW3-expressing P815 (P.CW3) mastocytoma and investigated whether IL-4 expression by the tumor affects tumor clearance and, if so, whether it alters the tumor-induced Vbeta10+ CD8+ T-cell response.
5273 16397274 P.CW3 were stably transfected with IL-4 or the empty control vector, and independent cell lines were injected i.p. into syngeneic DBA/2 mice.
5274 16397274 The IL-4-secreting P.CW3 tumor cells led to markedly higher mRNA expression of IL-4 and granzyme A and B but no differences in IFN-gamma and IL-2 production, cell proliferation, or ex vivo CTL activity in primary Vbeta10+ CD8+ T cells when compared with the control tumor cells.
5275 16397274 We concluded that tumor-derived IL-4 selectively changed the quality of the tumor-induced CD8+ T-cell response and resulted in unexpected negative effects on tumor clearance.

5286 16397274 The IL-4-secreting P.CW3 tumor cells led to markedly higher mRNA expression of IL-4 and granzyme A and B but no differences in IFN-gamma and IL-2 production, cell proliferation, or ex vivo CTL activity in primary Vbeta10+ CD8+ T cells when compared with the control tumor cells.
5287 16397274 We concluded that tumor-derived IL-4 selectively changed the quality of the tumor-induced CD8+ T-cell response and resulted in unexpected negative effects on tumor clearance.
5288 16397274 Tumor-derived interleukin-4 reduces tumor clearance and deviates the cytokine and granzyme profile of tumor-induced CD8+ T cells.
5289 16397274 An interleukin (IL)-4-containing tumor environment is reported to be beneficial for immune clearance of tumor cells in vivo; however, the effect of IL-4 on the effector CD8+ T cells contributing to tumor clearance is not well defined.

5306 16406168 In addition, the DNA vaccine elicited the production of IFN-gamma, but not IL-4 in splenocytes, suggesting the induction of a typical Th-1 dominated immune response in rats.
5307 16421599 Taking advantage of the HSVQuik system, we constructed three oncolytic HSV vectors that express mouse IL4, CD40 ligand and 6CK, respectively.
5308 16424174 Protein vaccines induce uncommitted IL-2-secreting human and mouse CD4 T cells, whereas infections induce more IFN-gamma-secreting cells.
5309 16424174 Mouse and human CD4 T cells primed during an immune response may differentiate into effector phenotypes such as Th1 (secreting IFN-gamma) or Th2 (secreting IL-4) that mediate effective immunity against different classes of pathogen.
5310 16424174 However, primed CD4 T cells can also remain uncommitted, secreting IL-2 and chemokines, but not IFN-gamma or IL-4.
5311 16424174 We now show that human CD4 T cells primed by protein vaccines mostly secreted IL-2, but not IFN-gamma, whereas in the same individuals most CD4 T cells initially primed by infection with live pathogens secreted IFN-gamma.
5312 16424174 We further demonstrate that many tetanus-specific IL-2+IFN-gamma- cells are uncommitted and that a single IL-2+IFN-gamma- cell can differentiate into Th1 or Th2 phenotypes following in vitro stimulation under appropriate polarizing conditions.
5313 16424174 In contrast, influenza-specific IL-2+IFN-gamma- CD4 cells maintained a Th1-like phenotype even under Th2-polarizing conditions.
5314 16424174 Similarly, adoptively transferred OTII transgenic mouse T cells secreted mainly IL-2 after priming with OVA in alum, but were biased toward IFN-gamma secretion when primed with the same OVA peptide presented as a pathogen Ag during live infection.

5322 16425132 Ten weeks after vaccination of neonates, percutaneous Japanese BCG had induced significantly higher frequencies of BCG-specific interferon- gamma -producing CD4(+) and CD8(+) T cells in BCG-stimulated whole blood than did intradermal Danish BCG.
5323 16425132 Similarly, percutaneous vaccination with Japanese BCG resulted in significantly greater secretion of the T helper 1-type cytokines interferon- gamma, tumor necrosis factor- alpha , and interleukin-2; significantly lower secretion of the T helper 2-type cytokine interleukin-4; and greater CD4(+) and CD8(+) T cell proliferation.
5324 16430961 The present study aimed to compare recombinant (r) and native (n) glutathione-S-transferase (GST) from Alternaria alternata.
5325 16430961 Cell supernatant revealed higher IL-4 and IL-5 levels with low levels of IFN-gamma.
5326 16432754 Although high levels of interferon-gamma and low levels of interleukin (IL)-4 and IL-10 were detected in mice immunized with DNA-hsp65 or MHSP/TDM, only animals immunized with MHSP/TDM displayed a consistent Th1 immune response, i.e., significantly higher levels of anti-soluble Leishmania antigen (SLA) immunoglobulin G (IgG)2a and low anti-SLA IgG1 antibodies.
5327 16439559 In addition, we show that levels of Th2-type cytokines (IL-10 and IL-4) are significantly lower in hMPV CTL epitope-vaccinated mice challenged with hMPV.
5328 16439580 The impact of BCG vaccination on anti-asthma in mice was not dependent on interferon-gamma, IL-4, and IL-10 levels.
5329 16446017 Oral vaccination stimulated the secretion of IFN-gamma and inhibited the secretion of IL-4 in spleen and mesenteric lymph nodes (MLN) of BALB/c mice.
5330 16446017 In vaccinated mice the proportion of CD4+ cells increased (p<0.05) in Peyer's patches (PP) and decreased (p<0.05) in spleen whereas the proportion of CD19+ cells decreased (p<0.05) in both PP and spleen, with regard to unvaccinated controls.
5331 16446174 Mice immunized with rSm22.6 induced production of IgG1 and IgG2a and synthesis of IFN-gamma and IL-4 in cultured mouse splenocytes.
5332 16446175 Culturing in the presence of granulocyte monocyte colony stimulating factor (GM-CSF) increased the in vitro differentiation and maturation of these cells into BM-derived DCs (CD11c+ and MHC class II+).
5333 16446175 Maturation of DCs was determined by increased CD80 and CD86 expression, IL-4 and IL-12 production, reduction in phagocytic capacity and increase in the antigen presenting ability to primed or naïve T lymphocytes.
5334 16465379 After co-culture with FO, IFN-gamma released from immunized T helper cells increased >10-fold, while IL-4 remained unchanged in comparison with control T cells.
5335 16466810 Interestingly, IL-4 was not produced in the absence of IL-12 in response to infection with L. amazonensis.

5345 16490926 In contrast, the co-administration of GM-CSF DNA enhanced the T cell-mediated immunity biased to the Th1-type, as judged by the significantly higher level of cytokine IL-2 and IFN-gamma production but not IL-4.
5346 16493050 Myeloid cells had a CD4+CD11b+CD11c+CD16+CD123(low)HLA-DR- phenotype, expressed myeloperoxidase, and included a population of M-CSFR+ monocyte-lineage committed cells.
5347 16493050 Further culture of myeloid cells in serum-free medium with GM-CSF and IL-4 generated cells that had typical dendritic morphology; expressed high levels of MHC class I and II molecules, CD1a, CD11c, CD80, CD86, DC-SIGN, and CD40; and were capable of Ag processing, triggering naive T cells in MLR, and presenting Ags to specific T cell clones through the MHC class I pathway.
5348 16493050 Incubation of DCs with A23187 calcium ionophore for 48 h induced an expression of mature DC markers CD83 and fascin.
5349 16493050 The combination of GM-CSF with IL-4 provided the best conditions for DC differentiation.

5356 16495544 Two and 4 months after challenge, delayed-type hypersensitivity (DTH) response, lung tissue affected by pneumonia, CFU, T-cell counts, and cytokine expression (interleukin-2 [IL-2], IL-4, IL-10, and gamma interferon) were determined.
5357 16499569 In addition, the DNA vaccine elicited the production of IFN-gamma, but not the production of IL-4 in spleen cells stimulated with recombinant FABP.
5358 16499575 These cells can be generated from peripheral blood monocytes cultured with granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4).
5359 16499575 We found that 24-h IFN-alpha co-culture of day 7 monocyte-derived DC generated with GM-CSF and IL-4 induces increased numbers of DC positive for CD54 and CD40 together with the co-stimulatory molecule CD80 but not the activation marker CD83.
5360 16499575 Also, IFN-alpha maturation leads to an increase in IP-10 and MCP-1 chemokine secretion, but only a minor increase in IL-12p40 secretion.

5364 16503117 DCs were from human peripheral blood monocytes cultured in the presence of granulocyte-macrophage colony stimulating factor, interleukin 4 and/or tumour necrosis factor alpha, and stimulated with Tca8113 cell lysate prepared by the freeze-thaw method.
5365 16503368 Results showed that a significant enhancement of proliferative and cytotoxic activities accompanied with increased IFN-gamma and TNF-alpha production as well as decreased IL-4 production were obtained from the mice vaccinated with 4T1-ITAC.
5366 16525093 A panel of naturally occurring polymorphic variant epitope peptides were made to the most commonly recognized epitope regions and tested for ability to elicit IFN-gamma, IL-4, and IL-10 production.
5367 16531819 The CD34(+) human acute myeloid leukemia-derived cell line MUTZ-3 is dependent on hematopoietic growth factors for its proliferation and is able to differentiate into dendritic cells (DCs) in response to the combination of granulocyte-macrophage colony-stimulating factor, interleukin-4, and tumor necrosis factor-alpha.

5385 16552035 Animals primed with the F. novicida DeltaiglC (KKF24) mutant induced robust splenic gamma interferon (IFN-gamma) and interleukin-12 (IL-12) recall responses with negligible IL-4 production as well as the production of antigen-specific serum immunoglobulin G1 (IgG1) and IgG2a antibodies.
5386 16552043 In response to nematode and malarial antigens, spleen cells from immunized nematode-infected mice produced significantly lower levels of gamma interferon but more interleukin-4 (IL-4), IL-13, and IL-10 in vitro than spleen cells from immunized nematode-free mice produced.
5387 16552043 Furthermore, H. polygyrus infection also induced a strong transforming growth factor beta1 response in vivo and in vitro.
5388 16552042 Immunization with CyaA-85A or CyaA-ESAT-6 in the absence of any adjuvant induced strong antigen-specific lymphoproliferative, interleukin-2 (IL-2) and gamma interferon (IFN-gamma) cytokine responses, in the absence of any IL-4 or IL-5 production.
5389 16571413 We detected a spectrum of lymphoproliferative response (median stimulation indices of 3.4), low precursor frequencies of interferon-gamma (median 0.11%) and interleukin-4 (median 0.05%) by Elispot, and cosecretion of Th1 and Th2 cytokines after measles virus stimulation.

5391 16579818 When stimulated with N. caninum tachyzoite lysates, splenocytes of vaccinated mice, cultured 5 and 10 wk after vaccination, secreted significant (P<0.05) levels of interferon gamma, interleukin (IL)-10, and small amounts of IL-4.
5392 16585215 CD1d-restricted natural killer T cells can down-regulate tumor immunosurveillance independent of interleukin-4 receptor-signal transducer and activator of transcription 6 or transforming growth factor-beta.
5393 16585215 Further, we examined the role of CD4(+) and/or CD8(+) cells by depleting the cells in vivo and measuring CTL activity in vitro.

5395 16585215 Further studies suggested that the rejection of tumor in CD1d KO mice was dependent on CD8(+) lymphocytes.
5396 16585215 Distinct from other murine tumor models, the negative regulation induced by CD1d-restricted NKT cells was not dependent on IL-4Ralpha-STAT6 signaling, including IL-13, or on TGF-beta.

5402 16596628 Expression of both Th1 cytokines (IL-2 and IFN-gamma) and Th2 cytokines (IL-4 and IL-10) was enhanced after DNA vaccination as compared to controls, with a bias towards Th1 response.
5403 16603096 We also evaluated the influence of specific immunotherapy on the serum level of IFN-G, sIL-2R, IL-4, IL-5 and IL-10 before treatment and after 4 years of therapy with the quantitative 2-step colorimetric sandwich ELISA method (R and D Systems).
5404 16603096 In the control group, a significant increase of serum IL-4 (p<0.01) as well as IL-5 (p<0.05) was registered at the end of the observation period.

5407 16603588 In B10.A mice, neutrophil depletion resulted in increased levels of interleukin (IL)-12 and IL-4 in the lungs, high levels of hepatic cytokines, and increased synthesis of T helper cell type 1 (Th1)- and Th2-regulated antibodies [immunoglobulin G1 (IgG1), IgA, and IgG3].
5408 16603588 In neutrophil-depleted A/J mice, high levels of pulmonary IL-12 and granulocyte macrophage-colony stimulating factor were concomitant to diminished levels of hepatic cytokines and increased amounts of Th1-regulated isotypes (IgG2a, IgG2b, and IgG3).
5409 16603614 These antigen-specific immunoproteins are thought to have immunoregulatory properties in the suppression of cell-mediated immunity (CMI) because they often associate with interleukin-10 (IL-10) and transforming growth factor beta.
5410 16603614 For 14 participants, the effect of mannan stimulation on TABM production and gamma interferon (IFN-gamma) and IL-4 mRNA expression by peripheral blood lymphocytes was also studied.
5411 16603614 In addition, the CAM-TABM level was directly related to mRNA expression for IL-4 but not IFN-gamma.

5419 16616574 MIC1/4-stimulated spleen cells from immunized mice produced IL-2, IL-12, IFN-gamma, IL-10, but not IL-4, suggesting the induction of a polarized Th1 type immune response.
5420 16616574 Our data demonstrate that MIC1 and MIC4 triggered a protective response against toxoplasmosis, and that these antigens are targets for the further development of a vaccine.
5421 16620826 While susceptibility to chronic infection is propagated by T helper cell type 1 cytokine responses (characterised by production of IL-12, IL-18 and interferon-gamma), immunity to intestinal-dwelling adult nematode worms is critically dependent on a type 2 cytokine response (controlled by CD4+T helper type 2 cells that secrete the cytokines IL-4, IL-5, IL-9 and IL-13).
5422 16621176 Naïve splenocytes produced high levels of TNF-alpha and IL-10 after incubation with LPS+ sonicate, while cells incubated with LPS- sonicate did not.
5423 16621176 Mice immunized with LPS+ sonicate developed a prominent innate response characterized by increased TNF-alpha and IL-10, as well as a strong antigen specific Th1 response including, IFN-gamma, IL-2 and high IgG2a serum titers.
5424 16621176 Mice that received LPS- sonicate were strongly Th2 biased in their immune response, with significantly more IL-4 than IFN-gamma and serum IgG1 titers higher than IgG2a.
5425 16622224 The OVA-specific immune response was characterized by high levels of serum IgG1 and increased production of interleukin-4 (IL-4), IL-5, or IL-10 from lymphoid cells of immunized animals, suggesting a Th2 response.
5426 16630673 These preliminary studies implicate conventional CD4+ T cells as the sole potential producers of IL-4 following immunisation with antigen prepared in aluminium adjuvants.
5427 16634802 The effect of M. bovis infection, 4 months post-challenge, was to suppress the expression of anti-inflammatory cytokines interleukin (IL)-4 and IL-10 as well as the pro-inflammatory cytokines tumour necrosis factor (TNF) and IL-6.
5428 16634802 Expression of interferon (IFN)-gamma and IL-12 was maintained.

5430 16634802 Also, vaccinated animals had higher levels of IL-4 and IL-10 transcripts compared to unvaccinated animals following challenge.
5431 16634802 These changes in cytokine expression levels led to a significant shift in the IFN-gamma/IL-4 or IFN-gamma/IL-10 ratio within the lymph node following challenge.

5451 16638213 BM-derived DCs were generated from bone marrow of 615 mice by culturing for 9 - 10 days in culture medium supplemented with GM-CSF and IL-4.
5452 16641286 Neonatal mice immunized intranasally with VP6/LT(R192G) were unprotected at 10 days postimmunization (dpi) and had no detectable rotavirus B-cell (antibody) or CD4(+) CD8(+) T-cell (rotavirus-inducible, Th1 [gamma interferon and interleukin-2 {IL-2}]-, Th2 [IL-5 and IL-4]-, or ThIL-17 [IL-17]-producing spleen cells) responses.
5453 16647169 IL-12- and IL-4-deficient mice were immunized to study the individual roles of Th1 and Th2 cells, respectively.
5454 16647169 While IL-4-deficient mice developed a protective immune response similar to that found in wild-type mice, it was not possible to induce protective immunity in the highly susceptible IL-12-deficient mice due to severe disease symptoms and death following inoculation of the SE vaccine strain (doses >or=5 x 10(2)CFU were lethal for IL-12-deficient mice).
5455 16647169 IL-12- and IL-4-deficient mice were immunized to study the individual roles of Th1 and Th2 cells, respectively.
5456 16647169 While IL-4-deficient mice developed a protective immune response similar to that found in wild-type mice, it was not possible to induce protective immunity in the highly susceptible IL-12-deficient mice due to severe disease symptoms and death following inoculation of the SE vaccine strain (doses >or=5 x 10(2)CFU were lethal for IL-12-deficient mice).
5457 16678312 IC31, the combination of a novel immunostimulatory oligodeoxynucleotide containing deoxy-Inosine/deoxy-Cytosine (ODN1a) and the antimicrobial peptide KLKL(5)KLK, represents a promising novel adjuvant signaling via the TLR9/MyD88-dependent pathway of the innate immune system.
5458 16678312 Activation of murine dendritic cells by IC31 induced efficiently proliferation of naïve CD4(+) TCR transgenic T cells (DO.11.10) as well as their differentiation into IFN-gamma- and IL-4-producing T cells in vitro.
5459 16699033 Following immunization of three different strains of mice (C57BL/6, BALB/c, and CBA) with either an equal number of Ad particles (resulting in a different total HA copy number) or different Ad particle numbers (to achieve the same HA copy number), the highest primary (immunoglobulin M [IgM]) and secondary (IgG) anti-HA humoral and cellular CD4 gamma interferon and interleukin-4 responses against HA were always achieved with the Ad vector carrying the HA epitope in fiber knob.
5460 16706787 We also identified a new chaperonin-10 promoter that was hyperexpressive compared with the heat shock protein-65 promoter.
5461 16706787 Splenocytes from recombinant bacillus Calmette-Guérin-immunized mice showed enhanced lymphocyte proliferation and interleukin-4 (but not interferon-gamma) secretion.
5462 16709016 The IL-4 and IL-13 pseudomonas exotoxins: new hope for brain tumor therapy.
5463 16709016 The authors have discovered that receptors for two cytokines, interleukin (IL)-4 and IL-13, are overexpressed on tumor biopsy samples and on cell lines derived from a variety of human tumors, including brain tumors.
5464 16709016 In human solid tumor cells, IL-4 binds to two chains (IL-4Ra and IL-13Ra1), whereas IL- 13 binds to three chains in many solid tumor cells, including glioma cells (to IL-4Ra, IL-13Ra1, and IL-13Ra2).
5465 16709016 To target IL-4Rs and IL-13Rs, the authors generated two recombinant fusion cytotoxins composed of IL-4 or IL-13 and a mutated form of pseudomonas exotoxin (PE), which for simplicity are called IL4-PE and IL13-PE in this paper.

5478 16712895 Levels of interleukin-10 (IL-10) produced by peripheral blood mononuclear cells (PBMC) seemed to inversely correlate with interferon-gamma responses.
5479 16712895 IL-2, IL-4 or transforming growth factor-beta responses were not detected at any time for neither of the vaccines.
5480 16712895 These results indicated a strong involvement of IFN-gamma, and maybe IL-10, in the development of immunity against PRRS virus.
5481 16714073 We studied the association between class II human leukocyte antigen (HLA)-DRB1*0301 presented measles virus (MV) peptide-specific cytokine responses and DQB1 and DPB1 alleles among 313 individuals who received two doses of measles-mumps-rubella-II vaccine.
5482 16714073 The overall median IFN-gamma secretion levels (first and third quartiles) for the 19-amino acid MV phosphoprotein (MV-P)- and 14-amino acid MV nucleoprotein (MV-N)-derived peptides were 27.7 pg/ml (1.8, 109.4) and 1.9 pg/ml (-6.2, 13.0), respectively; median IL-4 secretion levels were -0.6 pg/ml (-7.1, 6.2) and 2.4 pg/ml (-3.2, 9.3), respectively.
5483 16714073 A marginally significant increase in the frequency of the DQB1*0604 (p=0.02) allele was found among subjects who demonstrated detectable IL-4 levels to the MV-P peptide.
5484 16714073 Examination of IFN-gamma responses to MV-P and MV-N indicated that none of the individual alleles of the DQB1 and DPB1 loci were associated with peptide-induced T cell response.
5485 16714073 These data further confirm that HLA-DRB1 alleles are the major restriction molecules for MV-P and MV-N measles virus antigen presentation to T cells.
5486 16714073 We speculate that MV-P and MV-N peptides derived from DRB1*0301 could potentially be recognized in association with different HLA molecules, including DQB1 and DPB1; however, statistical adjustments for the effect of HLA-DR locus could potentially alter these genetic relationships.

5493 16734116 On the other hand, 20-30% of the schistosomiasis resistant individuals showed detectable levels of IL-2, IL-4 and IFN-gamma after stimulation with SmCaR, and 59% of them showed had anti SmCaR IgM specific antibodies.
5494 16737046 The second objective was to identify differences in CD4 and CD8 T cell numbers/kinetics/functions and levels of TH2 cytokines (IL4 and IL10) in different groups during the three-dose vaccination regimen. 40 HIV/AIDS patients were subdivided into groups 1A where patients had a high CD4 (> 200/mm3) count and IB where patients had a low CD4 (< 200/mm3) count.
5495 16737046 Detection of CD4 and CD8 cells was done by flowcytometry.
5496 16737046 TH2 type of cytokines IL4 and IL10 were estimated in the culture supernatant of PHA stimulated leukocyte rich plasma by sandwich ELISA.
5497 16737046 Both CD4 and CD8 cells increased significantly after vaccination in all the groups irrespective of the disease status.
5498 16737046 On the other hand, IL4/IL10 responses to PHA stimulation in the HIV-positive groups were much lower than in controls (P< 0.1).
5499 16737046 Cytokines IL4 and IL10 which regulate antibody response, were also lower in-patients and this together with a low CD4 count possibly accounted for the low anti-HBs levels.

5518 16760321 Peripheral blood leukocytes (PBL) from infected WTD expressed more gamma interferon (IFN-gamma), interleukin-12p40 (IL-12p40), granulocyte-monocyte colony-stimulating factor, and IL-4 mRNA than did PBL from uninfected deer; however, differences were not detected in expression of IL-10 and transforming growth factor-beta mRNA.
5519 16764688 Prior epicutaneous immunization results in reduced production of antigen-specific interferon-gamma and immunoglobulin G2a (IgG2a) and enhanced interleukin-4, IgG1 and IgE responses to immunization with CFA.
5520 16764688 Moreover, epicutaneous immunization converts an established Th1 response to a Th2 response, as demonstrated by the specific reduction of interferon-gamma and IgG2a and the enhancement of interleukin-4 and IgE.

5523 16790792 In order to quantify in vivo the mRNAs of cytokines which play important roles in leptospirosis, we have developed quantitative real-time PCR assays for interleukin-2 (IL-2), IL-4, IL-10, IL-12p40, tumor necrosis factor alpha (TNF-alpha), gamma interferon (IFN-gamma), transforming growth factor beta, and two housekeeping genes (encoding beta-actin and hypoxanthine phosphoribosyltransferase).
5524 16790792 In this kinetic study, there was pronounced expression of Th1 cytokine mRNA (TNF-alpha, IFN-gamma, and IL-12), with transcripts being detected as early as 1 h postinfection.
5525 16790792 Expression of anti-inflammatory cytokines, such as IL-4 and IL-10, was prominent in delayed samples from 1 to 4 days postinfection in response to infection with Leptospira interrogans.

5529 16790806 Both events require binding of Inv to beta1 integrins, which initiates signaling cascades including activation of focal adhesion complexes, Rac1, mitogen-activated protein kinase, and NF-kappaB.
5530 16790806 OVA-specific CD4 T cells produced both gamma interferon (IFN-gamma) and IL-4 as determined by enzyme-linked immunosorbent assay.
5531 16790806 Likewise, pronounced OVA-specific CD8 T-cell responses associated with IFN-gamma production were observed.
5532 16790806 Together, these results suggest that Inv might be an attractive tool in vaccination as it confers both host cell uptake and adjuvant activity by engagement of beta1 integrins of host cells, which leads to CD4 as well as CD8 T-cell responses.
5533 16801138 In the bronchoalveolar lavage fluid, the number of total cells and eosinophils was reduced, and regarding the change of cytokines, the concentration of IL-4 was also decreased, but interferon-gamma was increased in the co-administration group, opposed to the asthma group.
5534 16821115 A significant decrease of CD4 and CD8 naïve T cells and a corresponding increase of CD4 and CD8 memory T cells were found.
5535 16821115 The in vitro stimulation of PBMCs from elderly subjects with influenza antigens increased their proliferative capacity and the production of both IFNgamma and IL-4.
5536 16831210 Intranasal vaccination with antigen85A and antigen85B induced a significantly higher level of interferon-gamma, interleukin-12 and interleukin-4 in cervical lymph nodes together with IgA and IgG, predominantly IgG2a isotype in nasal secretion over subcutaneous vaccination.
5537 16842269 Cellular immune responses toward a Th1 subset mediated by IFN-gamma and TNF-alpha predominate in asymptomatic dogs exhibiting apparent resistance to visceral leishmaniasis.
5538 16842269 On the other hand, while the role of Th2 cytokines, such as IL-4 and IL-10, in symptomatic animals is still controversial, there is increasing evidence for a correlation of these cytokines with progressive disease.
5539 16860446 Splenocytes from immunized mice, stimulated in vitro, manifested a significant proliferative response accompanied by the production of high levels of interferon-gamma, but moderately elevated levels of interleukin-4, indicative of a predominantly Th1 type response.
5540 16862385 Assays of antibody isotype and IFN-gamma and IL-4 content in post-immunization serum showed that the fusion protein elicited a higher IgG2a titer and higher levels of IFN-gamma suggesting a potentiation of the Th1 immune response.
5541 16872726 The adjuvant RLJ-NE-299A up-regulated remarkably the expression of Th1 cytokines IL-2, IL-12, IFN-gamma, TNF alpha and Th2 cytokine IL-4 in lymph node cell cultures after 2 weeks of primary immunization with HBsAg.
5542 16874456 The IFN-gamma and IL-4 levels were quantified in the supernatants of specifically stimulated spleen cells.
5543 16874456 A respective 61%, 38% and 39% egg reduction was determined relative to those mice that only received the empty pVIVO2 plasmid. pVIVO(2)SjFABP-23 immunization increased IgG levels against SWAP and SEA.
5544 16885908 Similar effects using different cytokines such as GM-CSF, TNF-alpha, and IL-4 can be observed in acute myeloid leukemia and myelodysplastic syndromes.
5545 16887241 In the present study DnaJ (HSP40) of Salmonella enterica serovar Typhi has been evaluated for its immunogenicity and efficacy in protecting mice against lethal challenge by S. enterica serovar Typhimurium infection.
5546 16887241 Further there was an appreciable increase in IL-2, IL-4, IFN-gamma production in lymphocytes isolated from immunised mice as compared to control.
5547 16887980 The high transduction efficiency is in line with high expression levels of CD46 detected on migratory cutaneous DC, which proved to be further increased upon intradermal administration of GM-CSF and IL-4.
5548 16893994 Regarding cellular immunity, significant levels of gamma interferon (IFN-gamma) (1,100 +/- 157 pg/ml) and tumor necrosis factor alpha (650 +/- 42 pg/ml) but not interleukin-4 were detected in splenocyte culture supernatants of pCI-Ag85B-vaccinated mice following stimulation with recombinant Ag85B.
5549 16893994 Further, the main source of IFN-gamma is CD8(+) T cells, as demonstrated by intracellular cytokine staining.
5550 16901590 However, only the immunization with the PFR2-HSP70 fused genes triggers in spleen cells a statistically significant enhancement of expression of IL-12 and IFN-gamma and a decrease in the percentage of cells expressing IL-4.
5551 16914241 Impact of genetic variants in IL-4, IL-4 RA and IL-13 on the anti-pneumococcal antibody response.
5552 16914349 However, the use of pCI/IL-12 as adjuvant to pCI/Sm14 immunization failed to enhance protection against challenge infection.
5553 16914349 Protection induced by pCI/Sm14 immunization correlates with specific IgG antibody production against Sm14, Th1 type of immune response with high levels of interferon (IFN)-gamma and low levels of IL-4 in splenocyte culture supernatants and in bronchoalveolar lavage after challenge infection.
5554 16914349 IL-12 co-administration with pCI/Sm14 induced a significant production of nitric oxide in splenocyte culture supernatants and also lymphocyte suppression, with reduced percentage of T cells producing IFN-gamma and tumor necrosis factor-alpha.
5555 16918131 Autologous DCs were generated in vitro from peripheral blood monocytes in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4).
5556 16918131 DCs were pulsed with melanoma cell lysate from a cloned and selected melanoma cell line enriched in expression of MAGE-A antigens and deficient in expression of melanoma differentiation antigens: tyrosinase, MART-1 and gp100.
5557 16938461 The genes investigated were those that code for interleukin (IL)-1alpha, IL-1beta, IL-1R, IL-1RA, IL-4RA, IL-2, IL-4, IL-6, IL-10, IL-12, interferon-gamma (IFN-gamma), transforming growth factor-beta (TGF-beta), and tumor necrosis factor-alpha (TNF-alpha).
5558 16938461 Analyses of the data identified TGF-beta codon 25 GG (92.85% vs. 64.44%, p=0.04, OR=7.17), IL-4 -1098 GG (16.6% vs. 0.0%, p=0.05, OR=18.33), IL-10 -1082 GG (28.5% vs. 6.8%, p=0.05, OR=5.47), and IL-10 -1082 GCC/GCC (28.57% vs. 4.5%, p=0.025, OR=8.4) polymorphisms as risk factors for progression of bladder cancer.
5559 16938461 The genes investigated were those that code for interleukin (IL)-1alpha, IL-1beta, IL-1R, IL-1RA, IL-4RA, IL-2, IL-4, IL-6, IL-10, IL-12, interferon-gamma (IFN-gamma), transforming growth factor-beta (TGF-beta), and tumor necrosis factor-alpha (TNF-alpha).
5560 16938461 Analyses of the data identified TGF-beta codon 25 GG (92.85% vs. 64.44%, p=0.04, OR=7.17), IL-4 -1098 GG (16.6% vs. 0.0%, p=0.05, OR=18.33), IL-10 -1082 GG (28.5% vs. 6.8%, p=0.05, OR=5.47), and IL-10 -1082 GCC/GCC (28.57% vs. 4.5%, p=0.025, OR=8.4) polymorphisms as risk factors for progression of bladder cancer.
5561 16945454 Salviae co-administration significantly enhanced IFN-gamma and IL-2 cytokine producing splenocytes while ginseng induced high levels of IL-4 and IL-5 cytokine producing cells after challenge infection.
5562 16945454 Cells expressing an early activation marker CD69 and levels of a pro-inflammatory cytokine IL-6 were highly elevated in lungs from naïve mice during challenge virus infection, which might be a mechanism in lung inflammation leading to death.
5563 16945454 In contrast, immunized mice that were co-administered ginseng or Salviae modulated CD69 expressing immune cells, did not produce IL-6, and showed significant enhancement of influenza virus specific IgA antibody in lungs after challenge virus infection.
5564 16949577 Schistosoma mansoni infection was established using irradiated cercariae in Cercopithecus aethiops aethiops (Grivet monkey) to describe immune responses of the serum cytokines, IL-4, IL-10, IL-12, IFN- gamma, and TNF-alpha.
5565 16949577 In primary infection, IL-4 was significantly raised (p=0.03) in the immunized monkeys, and there was an insignificant increase (p>0.05) in IL-10.
5566 16949577 However, ova excretion did not influence the cytokines, except in the controls where both IL-4 and IL-10 were significantly increased (p<0.05).
5567 16949577 Schistosoma mansoni infection was established using irradiated cercariae in Cercopithecus aethiops aethiops (Grivet monkey) to describe immune responses of the serum cytokines, IL-4, IL-10, IL-12, IFN- gamma, and TNF-alpha.
5568 16949577 In primary infection, IL-4 was significantly raised (p=0.03) in the immunized monkeys, and there was an insignificant increase (p>0.05) in IL-10.
5569 16949577 However, ova excretion did not influence the cytokines, except in the controls where both IL-4 and IL-10 were significantly increased (p<0.05).
5570 16949577 Schistosoma mansoni infection was established using irradiated cercariae in Cercopithecus aethiops aethiops (Grivet monkey) to describe immune responses of the serum cytokines, IL-4, IL-10, IL-12, IFN- gamma, and TNF-alpha.
5571 16949577 In primary infection, IL-4 was significantly raised (p=0.03) in the immunized monkeys, and there was an insignificant increase (p>0.05) in IL-10.
5572 16949577 However, ova excretion did not influence the cytokines, except in the controls where both IL-4 and IL-10 were significantly increased (p<0.05).
5573 16950547 Rd significantly enhanced the interleukin-2 (IL-2), interferon-gamma (IFN-gamma), IL-4, and IL-10 mRNA expression in mice splenocyte induced by Con A.
5574 16951805 The obtained results showed that there is no statistical difference in interferon-g, interleukin (IL)-4 and IL-13 levels obtained with Smp40 stimulation compared with the control group (P > 0.05 for each).
5575 16951805 On the other hand, there were significant differences after Smp40 stimulation in IL-5 (P = 0.006) and IL-10 levels (P < 0.001) compared with the control group.
5576 16956640 Profiles of cytokines such as IFN-gamma, IL-2, IL-4, IL-5 and TGF-beta in immunized mice showed a naive T-cells bias to Th1 and Th3 polarization.
5577 16971810 Dendritic cells loaded with killed allogeneic melanoma cells can induce objective clinical responses and MART-1 specific CD8+ T-cell immunity.
5578 16971810 DCs were generated by culturing monocytes with granulocyte macrophage-colony stimulating factor (granulocyte macrophage-colony stimulating factor) and interleukin (IL-4) and activated by additional culture with tumor necrosis factor and CD40 ligand.
5579 16971810 Three out of 13 analyzed patients showed T-cell immunity to melanoma antigen recognized by autologous T cells (MART-1) tissue differentiation antigen.
5580 16971810 Two of 3 patients showed improved immune function after vaccinations demonstrated by improved secretion of interferon (IFN)-gamma or T-cell proliferation in response to MART-1 derived peptides.
5581 16971810 In one of these patients, vaccination led to elicitation of CD8 T-cell immunity specific to a novel peptide-derived from MART-1 antigen, suggesting that cross-priming/presentation of melanoma antigens by DC vaccine had occurred.
5582 16972041 Respiratory syncytial virus(RSV)-induced allergy may be controlled by IL-4 and CX3C fractalkine antagonists and CpG ODN as adjuvant: hypothesis and implications for treatment.
5583 16972041 Together with CpG ODNs that induce Toll-like receptor 9(+) (TLR9(+)) plasmacytoid dendritic cells to release type I IFN-alpha and -beta will reactivate the inhibited Th1 cells and the antiviral cytotoxic T leukocytes.
5584 16972040 It is hypothesized that the viral-soluble G glycoprotein (sG) contains a T cell superantigen (Tsag) that is capable of binding to the V(H)3 domain of IgE/FcepsilonRI(+) hematopoietic cells, basophils, mast cells and monocytes, similar to the case of allergens, and that this aggregation causes these innate system cells to degranulate and release large amounts of Th2 cytokines (IL-4, IL-5, IL-10, IL-13) into the blood.
5585 16972040 The review of the molecular research on the role of the viral fusion (F) and attachment (G) glycoproteins of RSV provided information on their role in the virus infection: early in infection the F glycoprotein induces Th1 cells to release the Th1 cytokines IL-2, IL-12 and IFN-gamma to activate precursors CTLs (pCTLs) to become anti-RSV CTLs.
5586 16972040 The gradual increase of sG molecules creates a gradient of fractalkine (FKN) which directs IL-5-activated eosinophils to the lungs of the patient.
5587 16987066 Our data indicate that 80% of the tumors expressed low levels of CD4 mRNA, with all of them expressing higher CD8 mRNA levels.
5588 16987066 Most tumors expressed interleukin (IL)-4 and IL-10 mRNAs and, most importantly, all of them expressed transforming growth factor (TGF)-beta1 and interferon gamma mRNA.
5589 16987066 None of the tumors studied expressed IL-12, IL-6, or tumor necrosis factor (TNF) mRNA.
5590 16988248 Elevated background levels of interleukin-6 (IL-6) (37.1 pg/ml versus 10.9 pg/ml [P = 0.04]), IL-4 (27.7 pg/ml versus 6.9 pg/ml [P = 0.02]), IL-10 (18.2 pg/ml versus 7.2 pg/ml [P < 0.001]), and gamma interferon (18.2 pg/ml versus 4.7 pg/ml [P = 0.006]) were noted in Sch(+) children compared to Sch(-) children without malaria.
5591 16988248 IL-6 and IL-10 levels were elevated in association with acute malaria, but the levels appeared to be blunted in Sch(+) children compared to Sch(-) children who were 4 to 8 years old (for IL-6, 96.2 pg/ml versus 137.2 pg/ml [P = 0.08]; for IL-10, 195.9 pg/ml versus 282.2 pg/ml [P = 0.06]).
5592 16996661 In this study aimed at developing a vaccine for humans, West Nile virus (WNV) envelope protein (E) and non-structural protein 1 (NS1) were produced in the Drosophila S2 cell expression system.
5593 16996661 The proteins were purified by immunoaffinity chromatography (IAC) using monoclonal antibodies that were flavivirus envelope protein group specific (for the 80E) or flavivirus NS1 group specific (for NS1).
5594 16996661 Splenocytes from immunized mice, cultured in vitro with the vaccine antigens as stimulants, showed excellent proliferation and production of cytokines (IFN-gamma, IL-4, IL-5, and IL-10).
5595 16997788 The frequency of Interferon-gamma and Interleukin (IL)-2 expressing CD4+/CD8+ T-cell subsets was significantly higher with a concomitant reduction in IL-4 and IL-10 expressing T-cells in the vaccine treated group as compared with the untreated controls.
5596 17011637 CD4(+) T lymphocytes and IL-4 rather than IL-10, or IFN-gamma were found to be the predominant cytokines associated with the clinical onset of allergic symptoms in C57BL/6 mice.
5597 17023392 N-linked glycosylation of IL-13R alpha2 is essential for optimal IL-13 inhibitory activity.
5598 17023392 The extracellular domain of IL-13R alpha2 (ECD alpha2) could be cleaved, which serves as a decoy receptor.
5599 17023392 The purified glycosylated ECD alpha2 efficiently inhibited IL-13-induced STAT6 phosphorylation in immune and Hodgkin's lymphoma cell lines, IL-13 binding, and cytotoxicity of IL-13 cytotoxin in various cancer cell lines.
5600 17023392 ECD alpha2 did not inhibit IL-4-induced STAT6 phosphorylation, indicating that inhibitory effects of ECD alpha2 are receptor specific.
5601 17028079 Both types of spores induced spleen and mesenteric lymph nodes cell proliferation as well as production of IFNgamma but not of IL-4 and IL-10 in both districts.
5602 17030407 The latter result was complied with a significant rise of IL-4 but not IFN-gamma positive CD4+ T-lymphocytes in NALT.
5603 17033714 Six weeks after BALB/c mice (H-2d) were immunized with 106 colony forming units (CFUs) BCG or rBCG, splenocyte proliferation was determined with MTT [3-(4,5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide] assay, IL-4 and interferon (IFN)-gamma produced by splenocytes were tested by enzyme linked immunosorbent assay (ELISA,) and the cytotoxicity of splenocytes from immunized mice to P815 cells (H-2d) expressing ESAT-6 protein was measured using CytoTox 96 Non-Radioactive Cytotoxicity Assay.
5604 17034859 The content of IgG, IgA, IgM, IL-2, IL-4, IL-6 and specific antibody titer as well as the number of immunocompetent cells were systematically analyzed in the vaccinated mice.
5605 17052667 This study reports immunological indices, including leukocyte phenotypes, intracellular cytokines IFN-gamma and IL-4 and antibody responses against vaccine antigens.
5606 17055124 The results showed that, compared to Tris-EDTA buffer (TE, 1 mM Tris, 0.1 mM EDTA, pH 8.0) injected mice, the expressions of Th1 type cytokine IFN-gamma, IL-2 and IL-12 were increased in hybrid phage, KLH-C, and wild phage immunized mice, and there were no differences between mice immunized with hybrid phage and KLH-C.
5607 17055124 While the expression of Th2 type cytokine IL-10 was similar in all mice, IL-4 was not detected.
5608 17055651 Measurement of interleukine (IL) levels (IL-4, IL-5, IL-12(p40)) and interferon-gamma (IFN-gamma) in the sera of mice immunized with pBMC2 indicated high levels of IL-4 and IL-5, although there were also significant levels of IFN-gamma.
5609 17058109 This immunization resulted in an enhanced Th1 immune response as measured by IgG2a antibody production and increased splenocyte IFN-gamma production, whereas no IL-4 was detected.
5610 17070626 Compared to unvaccinated infected chickens, vaccinated protected birds had lower expression of interleukin (IL)-6, IL-10 and IL-18 genes in spleen.
5611 17070626 However, there was no difference between these two groups of birds in the expression of interferon (IFN)-gamma, IL-4, IL-12 and inducible nitric oxide synthase (iNOS) genes on day 21 post-infection.
5612 17074291 The first assessment criteria was the follow-up of selected immunological parameters such as, antibody levels, lymphoproliferation, double positive CD4+CD8+ T lymphocytes and cytokine production (IL-2, IL-4, IFN-gamma).
5613 17074291 This better protection of BioMed animals seems to be correlated mainly with higher levels of antibodies and to a lesser extent with a slightly better CMI response and probably with the production of memory CD4+CD8+ T cells.
5614 17086102 The residue 129 polymorphism was also associated with distinct patterns of cytokine response: PrP 128-141 [129M] inducing IL-4 and IL-6 production, which was not seen in response to PrP 128-141 [129V].
5615 17086422 We further showed that the mechanisms involved in the inhibitory effect of C3d3 might be possible due to impairing the function of antigen presenting B lymphocytes and reducing the expression of transcription factors (T-bet and GATA-3) and cytokine IL-4.
5616 17090392 Intranasal vaccination with dmSEC induced the production of SEC-specific antibodies such as IgG1, IgG2b and IgA. dmSEC-vaccinated mice elicited significantly higher titers of interleukin-4 (IL-4) and IL-10, and lower levels of interferon-gamma (IFN-gamma) after challenge with S. aureus compared with the control group.
5617 17090392 Furthermore, the sera from dmSEC-immunized mice significantly inhibited IFN-gamma and tumor necrosis factor-alpha production in vitro.
5618 17092436 IgE levels in serum and IL-4/IL-13 levels in BALF were determined by ELISA.
5619 17092436 Expressions of STAT6 and NF-kappaB in lung were determined by immunohistochemistry staining.
5620 17092436 Significant reductions of eosinophil infiltration and levels of IL-4 and IL-13 in BALF were observed after vaccination.
5621 17092436 Further more, DNA vaccination inhibited STAT6 and NF-kappaB expression in lung tissue in Der p 2-immunized mice.
5622 17092436 IgE levels in serum and IL-4/IL-13 levels in BALF were determined by ELISA.
5623 17092436 Expressions of STAT6 and NF-kappaB in lung were determined by immunohistochemistry staining.
5624 17092436 Significant reductions of eosinophil infiltration and levels of IL-4 and IL-13 in BALF were observed after vaccination.
5625 17092436 Further more, DNA vaccination inhibited STAT6 and NF-kappaB expression in lung tissue in Der p 2-immunized mice.
5626 17101651 While vaccination with native CD increased the number of interleukin-2 (IL-2)- and gamma interferon-producing cells, rCD mainly stimulated IL-4-secreting cells.
5627 17114502 The current study shows that coadministration of plasmid DNA vaccines encoding IL-10 together with a plasmid encoding a myelin basic protein (MBP) encephalitogenic determinant during an ongoing disease rapidly amplifies this Tr1-mediated response, in a disease-specific manner.
5628 17114502 Tolerance could be transferred by MBP-specific primary T cells isolated from protected donors and reversed by neutralizing Abs to IL-10 but not to IL-4.
5629 17116174 To evaluate the effect of the genetic adjuvant of chemokines on the adaptive immune responses induced by a plasmid DNA vaccine expressing glycorotein B (gB) of the pseudorabies virus (PrV), a PrV DNA vaccine was co-inoculated with plasmid DNA expressing certain chemokines including CCL3 (MIP-1alpha), CCL4 (MIP-1beta), CCL5 (RANTES), CXCL8 (MIP-2), and CXCL10 (IP-10).
5630 17116174 A co-injection of the CCL3 plasmid DNA induced immunity that was biased to the T helper type 2 (Th2) pattern, as judged by the ratio of immunoglobulin G isotypes and the production of interleukin-4 cytokine generated from stimulated immune T cells.
5631 17116174 However, CCL5 and CXCL10 induced immune responses of the Th1-type, which rendered the recipients more resistant to a virulent virus infection.
5632 17118987 Intranasal immunization using recombinant CPAF (rCPAF) plus interleukin-12 (IL-12) (rCPAF+IL-12 immunization) was used to assess the protective immunity against genital Chlamydia muridarum infection in BALB/c mice. rCPAF+IL-12 immunization induced robust gamma interferon (IFN-gamma) production and minimal IL-4 production by splenocytes upon in vitro recall with rCPAF.
5633 17118987 This vaccination regimen also reduced the development of fibrosis and the influx of neutrophils into the upper genital tract when the animals were compared to mock-immunized (phosphate-buffered saline) animals after bacterial challenge. rCPAF+IL-12-mediated resolution of the bacterial infection and protection against Chlamydia-induced inflammatory disease were highly dependent on endogenous IFN-gamma production.
5634 17140708 In contrast, PCEP was associated with production of both IFNgamma and IL-4.
5635 17146974 The levels of IL-2 and RANTES showing a Th1 immune response were significantly increased, but there was no change in the level of IL-4 (Th2 immune response) in any of the immunized groups.
5636 17152936 Vaccinated neonatal BALB/c mice resisted infection with L. major, and lymphoid cells from the mice proliferated when restimulation with LmSEAgs and produced interferon-gamma and some interleukin-4.
5637 17152936 In addition, LmSEAgs stimulated human peripheral blood mononuclear cells to produce large amounts of interferon-gamma and some interleukin-5.
5638 17178178 Further, quantification of the gene expression induced by the stimulation with P-8 in asymptomatically infected dogs showed an up-regulation of IFN-gamma and TNF-alpha, which were three to 4-fold higher than that induced by soluble Leishmania antigen (SLA).
5639 17178178 While no measurable induction of IL-10 was observed, low levels of IL-4 mRNA were observed in response to both P-8 and SLA antigens.
5640 17179660 Protective immunity against Bordetella pertussis by a recombinant DNA vaccine and the effect of coinjection with a granulocyte-macrophage colony stimulating factor gene.
5641 17179660 Compared to those injected with pVAX1, the mice injected with pVAX1/ppf significantly elicited more antigen specific antibody anti-PTS1, anti-PRN, anti-FHA and cytokine IL-10, IFN-gamma.
5642 17179660 When pGM-CSF was coinjected with pVAX1/ppf, the mice showed significantly increases of the three antibodies and cytokine IL-10, IL-4, IFN-gamma and TNF-alpha compared to those injected with pVAX1 only.
5643 17179660 The mice in group pVAX1/ppf & pGM-CSF, in particular; induced much more anti-PTS1, IL-4 and TNF-alpha than those in group pVAX1/ppf.

5646 17179660 When pGM-CSF was coinjected with pVAX1/ppf, the mice showed significantly increases of the three antibodies and cytokine IL-10, IL-4, IFN-gamma and TNF-alpha compared to those injected with pVAX1 only.
5647 17179660 The mice in group pVAX1/ppf & pGM-CSF, in particular; induced much more anti-PTS1, IL-4 and TNF-alpha than those in group pVAX1/ppf.
5648 17182155 In these clinical trials we observed that CVD 909 immunization elicits a wide array of CMI, including cytotoxic T cells (CTL), IFN-gamma, TNF-alpha and IL-10 (but not IL-2, IL-4 or IL-5) production, and proliferation to S.
5649 17188704 Proteins incorporating rat sequences of IL-1RA, IL-2, IL-4, IL-10, or IL-13 were expressed as fusion proteins containing the major encephalitogenic region of myelin basic protein (MBP).
5650 17188704 In the case of the IL-2 and IL-4 fusion proteins, covalent linkage of the cytokine and neuroantigen domains resulted in synergistic antigen presentation.
5651 17188704 Proteins incorporating rat sequences of IL-1RA, IL-2, IL-4, IL-10, or IL-13 were expressed as fusion proteins containing the major encephalitogenic region of myelin basic protein (MBP).
5652 17188704 In the case of the IL-2 and IL-4 fusion proteins, covalent linkage of the cytokine and neuroantigen domains resulted in synergistic antigen presentation.
5653 17196231 Both MLV and IAV induced a different nature of immunity biased to Th1- and Th2-type, respectively, as judged by the ratio of PrV-specific IgG isotypes (IgG2a/IgG1) and the profile of cytokine IL-2, IL-4, and IFN-gamma production.
5654 17198083 DC pulsed with P. carinii did not demonstrate increased expression of the cell surface markers MHC II, CD40, CD54, CD80 (B7.1), and CD86 (B7.2).
5655 17198083 The release of interleukin (IL)-4 was increased, but there was no increase in the release of interleukin (IL)-12p40, IL-10, tumor necrosis factor-alpha, IL-6, and nitrite compared with naive DC.
5656 17198083 In vivo administration of DC pulsed with P. carinii induced a P. carinii-specific response, generating CD4+ cells that proliferated and released IL-4, but not interferon-gamma, in response to P. carinii-pulsed DC in vitro.
5657 17198083 DC pulsed with P. carinii did not demonstrate increased expression of the cell surface markers MHC II, CD40, CD54, CD80 (B7.1), and CD86 (B7.2).
5658 17198083 The release of interleukin (IL)-4 was increased, but there was no increase in the release of interleukin (IL)-12p40, IL-10, tumor necrosis factor-alpha, IL-6, and nitrite compared with naive DC.
5659 17198083 In vivo administration of DC pulsed with P. carinii induced a P. carinii-specific response, generating CD4+ cells that proliferated and released IL-4, but not interferon-gamma, in response to P. carinii-pulsed DC in vitro.
5660 17201665 Cytokines (interleukin [IL]-2, IL-4, and interferon-) in culture supernatants were determined by enzyme-linked immunosorbent assay.
5661 17213956 After the challenge infection, Sj22.7-driven interferon (IFN)-gamma and interleukin (IL)-4 was also quantified.
5662 17213956 The culture of spleen cells showed that secretion of IFN-gamma increased but IL-4 decreased.
5663 17213956 After the challenge infection, Sj22.7-driven interferon (IFN)-gamma and interleukin (IL)-4 was also quantified.
5664 17213956 The culture of spleen cells showed that secretion of IFN-gamma increased but IL-4 decreased.
5665 17223146 The titre of IgG and IgG1/IgG2 isotype to SPML vaccine in serum, the proliferation of lymphocytes, SPML-specific interferon-gamma (IFN-gamma) and IL-6, TNF-alpha, IL-4 production of PBMCs in vitro and IFN-gamma, IL-6, TNF-alpha, IL-4, IL-10 in piglets serum were examined to identify the immune responses of the piglets.
5666 17223970 Production of interleukin (IL)-5 and IL-10 accompanies T helper cell type 1 (Th1) cytokine responses to a major thyroid self-antigen, thyroglobulin, in health and autoimmune thyroid disease.
5667 17223970 Tumour necrosis factor (TNF)-alpha and interferon (IFN)-gamma exert detrimental effects in organ-specific autoimmune disease, while both destructive and protective roles have been demonstrated for interleukin (IL)-10, IL-4 and IL-5.
5668 17223970 Initially, TNF-alpha and IL-2 were produced in all three groups, accompanied by IL-10.
5669 17223970 Release of IFN-gamma, IL-4 and, notably, IL-5 ensued.
5670 17223970 Both patient groups exhibited increased TNF-alpha, IL-2, IFN-gamma and IL-10 responses, and PBMC from HT patients secreted lower amounts of IL-5 than male, but not female, controls.
5671 17223970 Conversely, higher production of TNF-alpha and IL-5 occurred in the presence of autologous sera than in the presence of pooled normal sera in both patient groups, indicating a dependency on serum constituents.
5672 17223970 Complement appeared to promote the production of IL-2 and particularly IL-5, the levels of which were reduced by neutralization of complement by heat- or zymosan treatment.
5673 17223970 The production of IFN-gamma and IL-2 of the three groups together correlated directly with the serum anti-Tg activity.
5674 17223970 Moreover, TNF-alpha, IFN-gamma, IL-5 and IL-10 responses were markedly inhibited by partial denaturation of Tg by boiling.
5675 17223970 Production of interleukin (IL)-5 and IL-10 accompanies T helper cell type 1 (Th1) cytokine responses to a major thyroid self-antigen, thyroglobulin, in health and autoimmune thyroid disease.
5676 17223970 Tumour necrosis factor (TNF)-alpha and interferon (IFN)-gamma exert detrimental effects in organ-specific autoimmune disease, while both destructive and protective roles have been demonstrated for interleukin (IL)-10, IL-4 and IL-5.
5677 17223970 Initially, TNF-alpha and IL-2 were produced in all three groups, accompanied by IL-10.
5678 17223970 Release of IFN-gamma, IL-4 and, notably, IL-5 ensued.
5679 17223970 Both patient groups exhibited increased TNF-alpha, IL-2, IFN-gamma and IL-10 responses, and PBMC from HT patients secreted lower amounts of IL-5 than male, but not female, controls.
5680 17223970 Conversely, higher production of TNF-alpha and IL-5 occurred in the presence of autologous sera than in the presence of pooled normal sera in both patient groups, indicating a dependency on serum constituents.
5681 17223970 Complement appeared to promote the production of IL-2 and particularly IL-5, the levels of which were reduced by neutralization of complement by heat- or zymosan treatment.
5682 17223970 The production of IFN-gamma and IL-2 of the three groups together correlated directly with the serum anti-Tg activity.
5683 17223970 Moreover, TNF-alpha, IFN-gamma, IL-5 and IL-10 responses were markedly inhibited by partial denaturation of Tg by boiling.
5684 17223975 Infection of Balb/c mice with M. tuberculosis SO2 was associated with comparatively lower levels of interferon (IFN)-gamma, interleukin (IL)-4 and tumour necrosis factor (TNF)-alpha and higher levels of inducible nitric oxide synthase (iNOS) during the late stage of infection, when compared with M. tuberculosis MT103 infection.
5685 17224210 Plasmids (pCI) carrying the genes of different cytokines including ovine IL-4(pCI-IL4), IL-10(pCI-IL10), GM-CSF(pCI-GMCSF), and MCP-1alpha(pCI-MCP1alpha), and pCI-IL4+pCI-GMCSF were co-delivered with pNPA.
5686 17224216 This led us to study bacterial clearance, lung pathology, lung TNF-alpha expression, and parameters of immediate hypersensitivity (IH), being serum IgE levels, eosinophil numbers in the bronchoalveolar lavage fluid, and ex vivo IL-4, IL-5, IL-10, IL-13, and IFN-gamma production by the bronchial lymph node cells.
5687 17229606 With immunotherapy, concentrations of both interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) were elevated in patients' sera, suggesting an intensification of the T helper1/ T helper 2-mediated responses in the XPV-treated patients.
5688 17239501 Chlamydia-specific cytokines including tumour necrosis factor-alpha (TNF-alpha) interleukin-10 (IL-10), interleukin-4 (IL-4), interleukin-12 (IL-12) and interferon-gamma (IFN-gamma) were detected in mice immunized either with selected DNA clones in spleen cells (0.2-135.2 pg/mL) or lymph nodes (0.15-84.9 pg/mL).
5689 17240003 The spleen cells of vaccinated mice produced significantly increased IFN-gamma and IL-4 concomitant with decreased IL-10 production during infection.
5690 17242926 Results showed that vaccination with GFT cells resulted in increased serum antibody to a PAIII cell lysate; reduced weight of the prostate/seminal vesicle complex and reduced incidence of prostate cancer in nude mice; increased splenocyte supernatant levels of TNF-alpha, IL-2, IFN-gamma and IL-12, cytokines associated with Th1 immunity; and increased splenocyte supernatant levels of IL-4 and IL-10, cytokines associated with Th2 immunity.
5691 17250802 Mice immunized with M720(+CpG) developed the highest HCVcp-specific titers of total IgG, IgG1, 2a, 2b, and that of IFN-gamma and IL-4 cytokines compared to all other groups.
5692 17250802 Hence, HCVcp formulated in M720 (with a synergistic effect by inclusion of CpG) could induce balanced and strong Th1/Th2 responses with long-lived CD4(-)CD8(+) CTLs.
5693 17257077 The mature human DCs generated from peripheral blood mononuclear cells (PBMCs) in the presence of granulocyte macrophage-colony-stimulating factor (GM-CSF), interleukin (IL)-4, and tumor necrosis factor (TNF)-alpha have widely contributed to their growing use in cancer vaccination trials.
5694 17257077 Our data show that mature DCs can be generated from PBMCs in both Dulbecco's modified Eagle's medium plus 10% FCS and serum-free AIM-V medium containing GM-CSF (100 ng/mL), IL-4 (100 ng/mL), and TNF-alpha (10 ng/mL).

5696 17257077 Our data show that mature DCs can be generated from PBMCs in both Dulbecco's modified Eagle's medium plus 10% FCS and serum-free AIM-V medium containing GM-CSF (100 ng/mL), IL-4 (100 ng/mL), and TNF-alpha (10 ng/mL).
5697 17258500 Human peripheral blood mononuclear cells from malaria-exposed immune adults (IA), malaria patients with varying severity, and malaria unexposed healthy donors were stimulated with recombinant exon2 protein and six synthetic peptides from its sequence to estimate the proliferative, IFN-gamma, and IL-4 responses.
5698 17258500 Positive proliferative, IFN-gamma, and IL-4 responses in IA group each were 60% with recombinant exon2 protein and 27-47% with different synthetic peptides.
5699 17258500 In malaria patients, frequency and magnitude of proliferative response, IL-4 concentration, and antibody recognition were far less than immune adults but IFN-gamma response was almost similar.

5704 17258500 Positive proliferative, IFN-gamma, and IL-4 responses in IA group each were 60% with recombinant exon2 protein and 27-47% with different synthetic peptides.
5705 17258500 In malaria patients, frequency and magnitude of proliferative response, IL-4 concentration, and antibody recognition were far less than immune adults but IFN-gamma response was almost similar.
5706 17258887 With immunotherapy concentrations of both interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) detectably elevated in patients' sera, suggesting intensification of T helper 1-/T helper 2-mediated responses in the XPV-treated patients.
5707 17270319 Enhanced production of IL-4 and IFN-gamma by CD4+ T cells indicated the participation of Th2- and Th1-type cells.
5708 17273752 Levels of 22 cytokines consisting of interleukin (IL)-1alpha, -1beta, -2, -4, -5, -6, -7, -8, -10, -12, -13, -15, -17, IFN-gamma, G-CSF, GM-CSF, TNF-alpha, IP-10, MIP-1alpha, RANTES, eotaxin and monocyte chemotactic protein-1 (MCP-1) were assessed.
5709 17273752 MCP-1, eotaxin, RANTES and GM-CSF levels were significantly elevated in BCa (P<0.009) and IL-1alpha and IL-4 levels were significantly decreased in BCa (P<0.015).
5710 17273752 Cytokine levels were generally elevated in NN patients compared to NP patients with the exception of eotaxin and IL-13, which were increased in NP patients.
5711 17273752 Three cytokines, IL-6, MIP-1alpha and G-CSF reached statistical significance (P<0.05).
5712 17273752 In 34 vaccinated BCa, MCP-1, eotaxin and IL-13 were significantly elevated post-vaccination with MCP-1 demonstrating the most significant response (median, 145.8-217.0 pg/ml, P=0.003).
5713 17274665 When beads were used as antigen carriers, bead size influenced antibody responses and induction of IFN-gamma-producing CD4 and CD8 T cells.
5714 17274665 Herein, we examine immunity induced by minute differences in nanobead size, specifically within a narrow viral-sized range (20, 40, 49, 67, 93, 101, and 123 nm), to see if bead carrier size influenced the induction of type 1 or type 2 cells as demonstrated by the production of IFN-gamma or IL-4.
5715 17274665 After one immunization with beads-OVA, IFN-gamma responses to both OVA and SIINFEKL were significantly better with 40 and 49 nm beads than other sizes, while, in contrast, IL-4 responses to OVA were higher after immunization with OVA conjugated to larger beads (93, 101, and 123 nm).
5716 17274665 Thus IFN-gamma induction from CD8 T cells was limited to 40-49 nm beads, while CD4 T cell activation and IL-4 were induced by 93-123 nm beads-OVA.
5717 17274665 After two immunizations, there were comparable high levels of IFN-gamma produced with 40 and 49 beads and IL-4 reactivity was still higher for larger beads (93, 101, 123 nm).
5718 17274665 Since protection against respiratory syncytial virus (RSV) depends on strong IFN responses, while IL-4 responses are reported to cause asthma-like symptoms, immunization with RSV antigens on the 49 nm carrier beads could provide the basis for a suitable vaccine.
5719 17274665 When the 49 nm beads were conjugated to RSV proteins G88 (surface) or M2.1 (internal capsid), one immunization with G88 induced high levels of IFN-gamma and low levels of IL-4.

5755 17275522 DC were propagated from C3H (H2(k)) bone marrow (BM) using granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4).
5756 17275522 Expression of major histocompatibility complex (MHC) class I and II was not affected, while CD40, CD80, and CD86 costimulatory molecules on DC were significantly inhibited by treatment with TGF-beta.
5757 17275522 This observation correlated with reduced interferon-gamma (IFN-gamma) and increased IL-10 production.
5758 17280751 While all three iscom preparations induced N. caninum specific antibodies at similar levels, His6-SA-SRS2' coupled to biotinylated matrix generated the strongest cellular responses measured as in vitro proliferation and production of interferon-gamma and interleukin-4 after antigen stimulation of spleen cells.
5759 17285277 Leukemic cells were stimulated (or not) with CD40L and IL-4.
5760 17285277 Elements of the antigen-processing machinery (MB1, LMP2, LMP7, LMP10, TAP1, TAP2, calnexin, calreticulin, tapasin, ERp57, zeta, delta) were determined by real-time PCR technique.
5761 17285277 The expression of important costimulatory and adhesion molecules considered as DC markers (CD40, CD54, CD80, CD83, CD86) were determined at the mRNA (PCR) and protein (flow cytometry) levels.
5762 17299718 Immunosuppression during active tuberculosis is characterized by decreased interferon- gamma production and CD25 expression with elevated forkhead box P3, transforming growth factor- beta , and interleukin-4 mRNA levels.
5763 17299718 All 3 groups displayed BCG-induced increases in effector and regulatory T cell phenotypes as defined by CD4(+)CD25(lo) and CD4(+)CD25(hi) T cells, respectively.
5764 17299718 In case patients with active disease, BCG stimulation induced the lowest increase of CD25, CD4(+)CD25(hi), CTLA-4, and interferon- gamma .
5765 17299718 However, these case patients expressed the highest mRNA levels of forkhead box P3, transforming growth factor (TGF)- beta , and interleukin (IL)-4 and a lower T-bet : GATA-3 ratio.
5766 17299718 There were no significant differences in IL-4 delta 2, IL-10, or TGF- beta receptor-II mRNA expression between groups.

5777 17301216 Virulence of R. equi depends on the presence of a large plasmid, which encodes a family of seven virulence-associated proteins (VapA and VapC to VapH).
5778 17301216 VapA and VapC induced the strongest lymphoproliferative responses for foals and adult horses.
5779 17301216 The ratio of IFN-gamma to IL-4 was significantly higher for foals than for adult horses for most Vap proteins.
5780 17301362 ELISA assays were performed on supernatants for measurement of IL-4, INF-gamma and IL-5.
5781 17306360 These should be directed at the level of gene selection and delivery, in order to identify the optimal cytokine and achieve efficient and durable cytokine expression, and at the level of improving immune stimulation, i.e. by co-administration of co-stimulatory molecules including B7 and CD40, or boosting the expression of tumor antigens or MHC class I molecules.
5782 17306360 Interestingly, some of the cytokines which have shown encouraging anti-tumor activity, including IFNs, IL-4, IL-12 and TNF-alpha, are endowed with anti-angiogenic or vasculotoxic effects, which may significantly contribute to local tumor control.
5783 17310492 Importantly, pcDS2 plus these co-stimulatory molecules elicited a higher level of IFN-gamma and IL-4 in CD4(+) T cells and a higher level of IFN-gamma in CD8(+) T cells.
5784 17310492 In addition, a significantly robust antigen-specific cytotoxic T lymphocyte (CTL) response and the production of long-term memory CD8(+) T cells were also observed in the groups immunized with pcDS2 plus 4-1BBL, OX40L, or CD70.
5785 17310492 Consistently, as late as 100 days after immunization, upregulated expressions of BCL-2, Spi2A, IL-7Ra, and IL-15Ra were still observed in mice immunized with pcDS2 plus these co-stimulatory molecules, suggesting the generation of memory T cells in these groups.
5786 17311933 It is noteworthy that in response to heat stress, mature DC produced higher levels of IL-12p70 and TNF-alpha, which are two cytokines involved in the stimulation of inflammatory reaction, whereas IL-10 production remained low.
5787 17311933 After heat-stress exposure, mature DC have the full ability to stimulate naive T cells with Th1 response polarization (high IFN-gamma and low IL-4 production) in an allogeneic MLR.
5788 17321645 IL-4 or IL-18 had little or no effect.
5789 17325890 Monocyte-derived DC cultured in the presence of granulocyte-macrophage colony-stimulating factor, interleukin (IL)-4 and tumor necrosis factor (TNF)-alpha expressed maturation markers, produced IL-12 and loaded apoptotic bodies to a similar extent to normal DC.
5790 17325890 Patients' circulating T and NK lymphocytes were normally represented and, after stimulation, were capable of producing TNF-alpha and interferon-gamma to a similar extent to control lymphocytes.
5791 17335944 ELISA analysis revealed there were predominant production of IFNgamma and IL-2 cytokines as compared to IL-4, and IL-10 productions in DS-treated mice.
5792 17335944 Our studies show that DS protects mice against disseminated candidiasis by the CD4+ Th1 immune response.
5793 17346135 To determine whether our vaccine strategy induced Th1 or Th2 immune responses, IFN-gamma and IL-4/IL-5 were measured.
5794 17346135 Intracellular IFN-gamma staining confirmed the ELISPOT results and demonstrated that the combined HIV/HCV group had significantly higher percentages of HIV and HCV-specific CD8+ T cells in comparison to the groups receiving the HIV or HCV vaccines.
5795 17346436 For all 26 patients blood samples were drawn just before (T0) and after 3 months of PMBL treatment (T3) to evaluate plasma IgE levels (total and allergen-specific) and the cytokine production involved in the allergic response (IL-4, IFN-gamma).
5796 17360887 This protection corresponded to significant increases in gamma interferon and low production of interleukin-4 (IL-4) IL-4 or IL-10, which suggested an enhanced type 1 response.
5797 17374885 Immunization with Rv1818c DNA induced a strong CD8+ cytotoxic lymphocyte and Th1-type response, with high levels of gamma interferon (IFN-gamma) and low levels of interleukin-4.
5798 17374885 Two nonameric peptides (Peptide(6-14) and Peptide(385-393)) from Rv1818c were identified by their ability to induce the production of IFN-gamma by CD8+ T cells in mice immunized with Rv1818c DNA.
5799 17375074 We programmed mouse bone marrow (BM) cells with lentiviral vectors (LV-GI4) so that they produced granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in an autonomous manner.

5801 17378240 CD40L and IL-4 stimulation of acute lymphoblastic leukemia cells results in upregulation of mRNA level of FLICE--an important component of apoptosis.
5802 17378240 Since it is still unclear whether CD40 ligation drives neoplastic B-cells to apoptosis or not, we assessed the mRNA expression of FLICE, FAS, FADD and TRADD - important components of apoptosis machinery, using real-time PCR in acute lymphoblastic leukemia cells before and after CD40 and IL-4 stimulation.
5803 17378240 ALL cells stimulated with CD40L/IL-4 expressed dendritic cell phenotype at mRNA and protein levels (upregulation of main costimulatory and adhesion molecules noted in real-time RT PCR and flow cytometry); they also expressed higher amounts of mRNA for FLICE, TRADD and FADD after CD40L/IL-4 stimulation.

5817 17385694 In the present study, DCs were generated from woodchuck peripheral blood mononuclear cells (wDCs) in the presence of human granulocyte macrophage colony-stimulating factor (hGM-CSF) and human interleukin 4 (hIL-4).
5818 17386022 Furthermore, the modified VLP displayed a significantly stronger immunogenicity than other five recombinant proteins and GST-BTB with a higher titer of peptide-specific and virus-specific antibody, elevated IFN-gamma and interleukin-4 production, especially enhanced lymphocyte proliferation.
5819 17397893 The association between HLA homozygosity and measles-specific Th(1) (IFN-gamma, IL-2 and IL-12p40) and Th(2) (IL-4 and IL-10) cytokine responses were assessed in a group of 339 healthy schoolchildren 12-18 years of age previously immunized with two doses of live-attenuated measles virus vaccine.
5820 17409222 Clearance of R. equi depends mainly on gamma interferon (IFN-gamma) production by T lymphocytes, whereas the predominance of interleukin 4 (IL-4) is detrimental.
5821 17409222 Infected foals had significantly lower IL-4 mRNA expression but significantly higher IFN-gamma expression and IFN-gamma/IL-4 ratio in R. equi-stimulated BLN lymphocytes than did infected adults.
5822 17409222 This study demonstrates that the immune response to R. equi in foals is not biased toward IL-4 and is characterized by the predominant induction of IFN-gamma.
5823 17409222 Clearance of R. equi depends mainly on gamma interferon (IFN-gamma) production by T lymphocytes, whereas the predominance of interleukin 4 (IL-4) is detrimental.

5829 17410612 Recombinant bacteria carrying eukaryotic expression vectors encoding the murine IL-4 or IL-18 genes were administered to groups of mice with established subcutaneous melanoma tumors.
5830 17412629 Immunoprotection led to reversal of DTH anergy, increased levels of antibodies and pulmonary IL-12, IL-2 and IL-4 indicating a balanced type 1/type 2 response.
5831 17412629 Depletion experiments showed that immunoprotection required the cooperative action of CD4(+) and CD8(+) T cells in association with IFN-gamma and IL-12.
5832 17430546 In response to in vitro stimulation with SLA, spleen cells from mice that had received oligomannose-coated liposomes encasing SLA (SLA-OML) displayed greater interferon (IFN)-gamma and interleukin (IL)-2 production and lower IL-4 and IL-5 production than spleen cells from mice that had received SLA alone, indicating that the SLA-specific Th1 immune response had predominantly been induced in the mice that had received SLA-OML.
5833 17442307 Analysis of the protective immune responses showed that the protein immunization promoted a Th2-biased response with an increase in IL-4, IL-5 and IgG1 responses, whereas, the DNA vaccine promoted a Th1-biased response with profound IFN-gamma and IgG2a responses.
5834 17451293 Thus, Th l type cells produce IL-2 and IFN y, whereas Th 2 cells produce IL-4 and IL-5.
5835 17451465 Mice were immunized with recombinant NS3 protein (rNS3) and poly (I:C) emulsified in Montanide ISA 720 (M720).
5836 17451465 Cytokine production was assayed by enzyme-linked immunospot assay, and CD4(+) IFN-gamma(+) T helper (Th) cells or CD8(+) IFN-gamma(+) cytotoxic T lymphocytes were detected by flow cytometry.
5837 17451465 The cytokine profiles showed that this formulation induced a Th1-biased immune response with several-fold more interferon-gamma (IFN-gamma)-producing cells than interleukin-4-producing cells.
5838 17451465 The frequency of IFN-gamma-producing CD4(+) and CD8(+) cells induced by rNS3 in poly (I:C) and M720 was significantly higher than that induced by rNS3, rNS3 in M720, or rNS3 in poly (I:C), and was comparable to that induced by rNS3 in CpG-ODN with M720.
5839 17451739 Here we describe extensive studies to optimize and quantitatively validate the 8-color ICS assay for use in clinical trials of candidate vaccines, which includes measurement of viable IFN-gamma, IL-2, TNF-alpha and IL-4 producing CD4+ and CD8+ T cells.
5840 17464770 The frequency of IFN-gamma and IL-2 expressing CD4(+)/CD8(+)T-cell subsets was significantly higher with a concomitant reduction in IL-4 and IL-10 expression in the vaccine-treated group (p<0.0001) compared with the untreated controls.
5841 17466906 The adjuvant effect of beta-glu6 was evident in the increase of T and B cell activation in response to HBsAg, as judged by the percentage of CD69-positive CD4(+) and CD19(+) lymphocytes in the spleen. beta-glu6 could significantly enhance the number of IL-4-producing cells in response to HBsAg, while it had no effect on the number of IFN-gamma-producing lymphocytes, suggesting a Th2 bias of the immune response.
5842 17485153 Both aluminum-containing adjuvants significantly increased the expression of CD86 on DCs but only aluminum hydroxide adjuvant also induced moderate expression of CD80.
5843 17485153 Aluminum-containing adjuvants stimulated the release of IL-1beta and IL-18 from DCs via caspase-1 activation.

5845 17485153 Addition of neutralizing anti-IL-1beta antibodies decreased IL-5 production and addition of anti-IL-18 antibodies decreased both IL-4 and IL-5 production.
5846 17485153 Inhibition of IL-1beta and IL-18 secretion by DCs via inhibition of caspase-1 also led to a marked decrease of IL-4 and IL-5 by CD4(+) T cells.
5847 17485153 These results indicate that aluminum-containing adjuvants activate DCs and influence their ability to direct T(H)1 and T(H)2 responses through the secretion of IL-1beta and IL-18.
5848 17485153 Both aluminum-containing adjuvants significantly increased the expression of CD86 on DCs but only aluminum hydroxide adjuvant also induced moderate expression of CD80.

5860 17485322 The therapeutic efficacy of the DC vaccine was associated with increased tumor-specific IFN-g and IL-4 T-cell responses and cytolytic activity of splenic T cells.
5861 17485453 In the absence of CD154, administration of interleukin-12 restores Th1 responses but not protective immunity to Schistosoma mansoni.
5862 17485453 Here we demonstrate the importance of CD40/CD154 in vaccine-induced immunity, as CD154(-/-) mice exposed to RA schistosomes develop no protection to challenge infection.
5863 17485453 We showed that vaccinated CD154(-/-) mice have defective Th1-associated immune responses in the skin-draining lymph nodes and the lungs, with reduced or absent levels of interleukin-12p40 (IL-12p40), gamma interferon, and nitric oxide, but elevated levels of lung IL-4 and IL-5.
5864 17485453 On the other hand, the administration of recombinant IL-12 (rIL-12) to CD154(-/-) mice shortly after vaccination caused elevated and sustained levels of Th1-associated cytokines, rescued MHC-II expression by lung CD11c(+) cells, and restored the appearance of inflammatory effector foci in the lungs.
5865 17494641 Vaccination with either LPS analog resulted in reduced lung eosinophilia, reduced eosinophil numbers in the bronchoalveolar lavage fluid, and the ex vivo production of interleukin-4 (IL-4) by bronchial lymph node cells and IL-5 by spleen cells, suggesting reduced type I hypersensitivity.
5866 17497212 As a result, although the plasmid encoding only VP1 could elicit virus-binding antibody detected by ELISA, splenocyte proliferation, IL-4 and IFN-gamma production, the levels were significantly less than C3d/M28-VP1 fusion.
5867 17498814 Blood samples of probiotic-treated piglets showed a significantly lower frequency of CD8(high)/CD3+ T cells and CD8(low)/CD3+ T cells and a significant higher CD4+/CD8+ ratio.
5868 17498814 IL-4 and IFN-gamma production of polyclonally stimulated PBMCs was on average higher in the probiotic group.
5869 17498851 The effect was determined in the form of protective anti-HBsAg titers, neutralizing antibodies (IgG1 and IgG2a), spleen cell lymphocyte proliferation by using MTT assay, Th1 (IFN-gamma and TNF-alpha) and Th2 (IL-4) cytokines as well as T-lymphocyte subsets (CD4/CD8) and intracellular cytokines (IFN-gamma/IL-4), these responses were highest in BOS 2000 immunized mice.
5870 17498851 In contrast, BOS 2000 was associated with production of both IFN-gamma and IL-4.
5871 17498851 The effect was determined in the form of protective anti-HBsAg titers, neutralizing antibodies (IgG1 and IgG2a), spleen cell lymphocyte proliferation by using MTT assay, Th1 (IFN-gamma and TNF-alpha) and Th2 (IL-4) cytokines as well as T-lymphocyte subsets (CD4/CD8) and intracellular cytokines (IFN-gamma/IL-4), these responses were highest in BOS 2000 immunized mice.

5873 17504117 The presence of a background mixed IFN-gamma and Th2 response to mycobacterial antigens before infection with M. tuberculosis (Mtb), and the development of a large IL-4 response during progressive TB, are characteristics of individuals in the locations where BCG fails, which are also seen in animal models in the same countries.
5874 17504117 We outline how IL-4 (and IL-13) can undermine Th1-mediated immunity and drive inappropriate alternative activation of macrophages.
5875 17504117 The mechanisms of the effects of IL-4 include impaired antimicrobial activity due to reduced TNF-alpha-mediated apoptosis of infected cells, reduced activity of iNOS, increased availability of iron to intracellular Mtb, and increased proliferation of antigen-specific FOXP-3+ regulatory T cells.
5876 17504117 IL-4 also increases the toxicity of TNF-alpha and drives pulmonary fibrosis, thus enhancing immunopathology.

5889 17532057 Human peripheral blood CD14(+) monocytes were purified by using a magnetic separation column and cultured with GM-CSF and IL-4 to differentiate into immature DCs (iDCs).
5890 17532057 In the presence of Talpha1, iDC surface markers CD40, CD80, MHC class I and class II molecules were significantly upregulated as measured by flow cytemotry analysis.
5891 17532057 Thus, Talpha1 significantly enhances DC differentiation, activation, and functions from human peripheral blood CD14(+) monocytes possibly through a mechanism of the activation of p38 MAPK and NFkappaB pathways.
5892 17543425 Animals were sacrificed on days 4, 7, and 10 post-challenge and lungs were removed for viral quantitation, histopathology, and cytokine mRNA expression analysis (interferon-gamma (IFN-gamma) and interleukin-4 (IL-4)).
5893 17548134 CD4(+) T-cell responses were also elicited as shown by the enhancement of T-cell proliferation, IFN-gamma and IL-4 level.
5894 17548173 Both fusion protein-induced Th1-like cytokine (IFN-gamma) and Th2-like cytokine (IL-4) were identified.
5895 17563737 PBMC were collected at 6, 9 and 15 months after transplantation and stimulated with a combination of CD2 and CD28 monoclonal antibodies, with PHA or with tetanus toxoid as recall antigen.
5896 17563737 A multiplex enzyme linked immunoassay was used to determine levels of Th1 cytokines IL-2, IFN-gamma and tumour-necrosis factor-alpha (TNF-alpha), Th2 cytokines IL-4, IL-5 and IL-13, the regulatory cytokine IL-10 and the proinflammatory cytokines IL-1alpha, IL-1beta, IL-6 and the chemokine IL-8.
5897 17563737 Production of Th2 cytokines IL-5 and IL-13 was superior to production of Th1 cytokines IFN-gamma and TNF-alpha.
5898 17570105 This pathway involves enhanced induction of CD8(+) cytotoxic T lymphocytes (CTLs) and down-regulation of interleukin-4 and transforming growth factor- beta , leading to further enhancement of the activity of CD8(+) CTLs and of other microbicidal pathways.
5899 17570108 Fever after smallpox vaccination is associated with specific haplotypes in the interleukin (IL)-1 gene complex and in the IL18 gene.

5937 17585683 And they are adding cytokines such as granulocyte macrophage colony stimulating factor or interleukin 4 during dendritic cell growth or maturation or at the site of vaccination to try to boost response.
5938 17587500 The production of IL-12 and IFN-gamma, for example, resulting from exposure to many bacterial, viral, and protozoan pathogens is responsible for Th1-derived protective responses that also can inhibit development of Th2-cells expressing IL-4-dependent immunity to extracellular helminth parasites and vice versa.
5939 17596432 In vaccine recipients, incubation with L1 VLP in vitro led to a statistically significant increase in production of Th1 (granulocyte-macrophage colony-stimulating factor, interleukin-2 [IL-2], gamma interferon; P < 0.0007) and Th2 (IL-4, IL-5, IL-10, IL-13; P < 0.0017) cytokines and the chemokine IP-10 (P = 0.0021) at month 2 after immunization, compared to levels seen prior to vaccination.
5940 17616706 Further characterizing the expression of a panel of homing receptors on Tc1 and Tc2 cells, we found that very late antigen (VLA)-4 (a heterodimer of CD49d and CD29), but none of other receptors evaluated, was expressed at significantly higher levels on Tc1 cells than on Tc2 cells.
5941 17616706 Although CD49d (alpha(4) integrin) can form heterodimers with both beta(1) (CD29) and beta(7) integrins, alpha(4)beta(7) complexes were not expressed by either Tc1 or Tc2 cells, suggesting that CD49d is solely expressed in VLA-4 complexes.
5942 17616706 VLA-4 expression on Tc2 cells was down-regulated in an interleukin (IL)-4 dose-dependent manner but not by other type 2 cytokines, such as IL-10 and IL-13, suggesting that IL-4 uniquely down-regulates VLA-4 expression on these cells.
5943 17616706 Finally, the efficient trafficking of Tc1 cells into intracranial M05 lesions in vivo was efficiently blocked by administration of monoclonal antibodies against CD49d or VCAM-1 or small interfering RNA-mediated silencing of CD49d on Tc1 cells.
5944 17628695 Expression of IFN-gamma, TNF-alpha, iNOS and IL-4 by PBMC increased in response to infection, whereas, IL-10 expression decreased.
5945 17628695 Cells from animals in the high pathology group expressed more IFN-gamma, TNF-alpha, iNOS and IL-4 than did animals in the low pathology group at early time points.
5946 17628695 IFN-gamma and iNOS gene expression were significantly greater in tissues from infected animals compared to tissues from uninfected animals.
5947 17628695 Expression of IFN-gamma, TNF-alpha, iNOS and IL-4 by PBMC increased in response to infection, whereas, IL-10 expression decreased.
5948 17628695 Cells from animals in the high pathology group expressed more IFN-gamma, TNF-alpha, iNOS and IL-4 than did animals in the low pathology group at early time points.
5949 17628695 IFN-gamma and iNOS gene expression were significantly greater in tissues from infected animals compared to tissues from uninfected animals.
5950 17629370 In contrast, the absence of endogenous IL-12/IL-23 or IL-4 had little impact on the magnitude of the antibody response but instead caused a dramatic change in the pattern of IgG isotypes.
5951 17629370 IFN-gamma was produced by NK, dendritic cells, CD4+ and CD8+ T cells stimulated in vitro with CpG ODN.
5952 17629370 Adoptive transfer experiments confirmed that CD4+ or CD8+ T cells were in fact relevant sources of IFN-gamma in vivo.
5953 17629370 Following CpG ODN injection, splenic dendritic cells from IFN-gamma deficient mice did not up-regulate CD86 or CD40 expression, suggesting a role for these molecules.
5954 17629370 The importance of CD28 (CD86 ligand) was confirmed using CD28 deficient mice which presented severely impaired immune responses following CpG ODN-assisted immunization.
5955 17629372 The mice immunized with Lip-rgp63-CpG ODN also showed the lowest spleen parasite burden, highest IgG2a/IgG1 ratio and IFN-gamma production and the lowest IL-4 production compared to the other groups.
5956 17629376 The Th(1) (TNF-alpha, IL-12p70, IFN-gamma, IL-2) and Th(2) (IL-10, IL-4 and IL-5) cytokine profiles were analyzed after stimulation of spleen cells from mice immunized with purified RF-412 protein.
5957 17641838 Peripheral blood monocytes were cultured in vitro with GM-CSF, IL-4 for 6 days, then TNF-(the TNF-group) or TNF-, IL-1, IL-6, PGE2 (the cytokine mixture group) were added to promote maturation.
5958 17641838 Cell number was counted by hematology analyzer, and phenotype study (CD1a, CD14, CD83) was carried out by flow cytometry, and the function of DCs was examined by mixed lymphocyte reaction.
5959 17641838 The phenotypes were as follows: CD1a+ (74.65+/-4.45)%, CD83+ (39.50+/-4.16)%, CD14+ (2.90+/-1.76)% in TNF-alpha group, and CD1a+ (81.86+/-5.87)%, CD83+ (81.65+/-6.36)%, CD14+ (2.46+/-1.68)% in the cytokine mixture group.
5960 17641838 It was concluded that leucapheresis may be a feasible way to provide large number of peripheral blood monocytes for DC generation, and combined administration of TNF-, IL-1, IL-6, and PGE2 may greatly promote maturity.
5961 17644455 Immunization with either A2 (A2-pCDNA3) or NH (NH-VR1012) DNA induced an elevated IFN-gamma production before infection; however, only A2 DNA immunized mice were protected against both Leishmania species and displayed a sustained IFN-gamma production and very low IL-4 and IL-10 levels, after challenge.
5962 17644455 Mice immunized with NH/A2 DNA produced higher levels of IFN-gamma in response to both specific recombinant proteins (rNH or rA2), but displayed higher IL-4 and IL-10 levels and increased edema and parasite loads after L. amazonensis infection, as compared to A2 DNA immunized animals.
5963 17644455 Immunization with either A2 (A2-pCDNA3) or NH (NH-VR1012) DNA induced an elevated IFN-gamma production before infection; however, only A2 DNA immunized mice were protected against both Leishmania species and displayed a sustained IFN-gamma production and very low IL-4 and IL-10 levels, after challenge.
5964 17644455 Mice immunized with NH/A2 DNA produced higher levels of IFN-gamma in response to both specific recombinant proteins (rNH or rA2), but displayed higher IL-4 and IL-10 levels and increased edema and parasite loads after L. amazonensis infection, as compared to A2 DNA immunized animals.
5965 17655984 Production of both IFN-gamma and IL-4 with a dominance of Th1 response following immunization was required for optimum success against L. donovani infection in BALB/c mice.
5966 17655984 The success of immunotherapy exhibited an immune modulation with surge in Th1 cytokines, IFN-gamma and IL-12 with extreme down regulation of disease promoting IL-4 and IL-10.
5967 17655984 Production of both IFN-gamma and IL-4 with a dominance of Th1 response following immunization was required for optimum success against L. donovani infection in BALB/c mice.
5968 17655984 The success of immunotherapy exhibited an immune modulation with surge in Th1 cytokines, IFN-gamma and IL-12 with extreme down regulation of disease promoting IL-4 and IL-10.
5969 17659370 ITAC-recruited TILs exhibited 4T1-specific proliferation and cytotoxicity, and an increased IFN-gamma but decreased IL-4 production.
5970 17678715 Cytokine levels (IL-4, IL-10, IL-18 and IFN-gamma) were measured by ELISA in plasma and washes from the terminal small bowel 24h after oral challenge.
5971 17678715 Unlike the infection with the wild type strain, no IFN-gamma response and low IL-18 intestinal levels were found in pigs infected with the protease mutants.
5972 17678715 IFN-gamma and IL-18 response therefore did not correlate with the virulence of Salmonella Typhimurium.
5973 17680799 In addition, VLPs elicited cell-mediated immunity as demonstrated by enhanced interferon-gamma and interleukin-4 production.
5974 17681650 The DNA-IL-12(+) group had stronger antigen-specific IFN-gamma ELISPOT activities and higher levels of antigen-specific CD4(+) and CD8(+) T cell responses than either the DNA-IL-12(-) or positive control groups.
5975 17681650 In addition, its mean concentrations of IFN-gamma and IL-2 were about 2.5- to 4.5-fold higher than those observed in the DNA-IL-12(-)-treated mice, and were significantly higher than control groups (P<0.01 or P<0.001), whereas IL-4 and IL-10 secretion were lower.
5976 17682721 [CD8+ and CD4+ T lymphocyte responses against malaria].
5977 17682721 The development and maintenance of memory CD8+ T cell response are closely related to the CD4+ T cells together with interleukin (IL)-4, IL-7, IL-15 and IL-2.
5978 17682721 CD4+ T cells also play a triple role in the immune response to malaria parasites; by activating B cells to produce high level of antimalarial antibodies, by enhancing the induction of CD8+ T cell responses, and by inhibiting the development of liver stage parasites.
5979 17682721 Although it has been known much about CD8+ T and CD4+ T cell responses, cross-talking mechanisms of these cells, and other factors which contribute to this response during malaria so far, many questions also need to be answered in the future.
5980 17682721 In this review article, CD8+ T and CD4+ T cell responses to malaria infection have been discussed in the light of current literature.
5981 17686554 In addition, after in vitro stimulation with rSurA, spleen cells from rSurA-immunized mice produced interleukin-2 (IL-2), interferon (IFN)-gamma, IL-4 and IL-5.
5982 17686554 Spleen cells from mice immunized with rDnaK plus adjuvant secreted IFN-gamma and IL-2 upon stimulation with rDnaK and induced a specific cytotoxic response.
5983 17700709 These CD4(+)KJI-26(+) cells were only transiently activated and produced IL-10 and IL-4 and not IFN-gamma.
5984 17707955 The immune responses observed in the vaccinated animals showed that the production of IFNgamma and the absence of IL-4, accompanied by a strong humoral response, are insufficient to elicit protection against S. mansoni.
5985 17725100 For this purpose, eighteen patients with relapsed or refractory cancer were vaccinated with peripheral monocyte-derived DCs generated with GM-CSF and IL-4, and pulsed consequently with 100 microg/ml of tumor lysate before maturation in culture in the presence of IL-1beta, PGE2 and TNF alpha for two days.
5986 17785828 After priming with IFN-gamma and stimulation with NadADelta351-405, mo-DCs strongly up-regulated maturation markers CD83, CD86, CD80, and HLA-DR, secreted moderate quantities of TNF-alpha, IL-6, and IL-8, and produced a slight, although significant, amount of IL-12p70.
5987 17785828 Costimulation of mo-DCs with NadADelta351-405 and the imidoazoquinoline drug R-848, believed to mimic bacterial RNA, increased CD86 in an additive way, but strongly synergized the secretion of IL-12p70, IL-1, IL-6, TNF-alpha, and MIP-1alpha, especially after IFN-gamma priming.
5988 17785828 CD86/CD80 overexpression correlated with the occupation of high-(kd approximately 80 nM) and low-(kd approximately 4 muM) affinity binding sites for NadADelta351-405.
5989 17785828 Alternatively, secretion of IL-12p70 and TNF-alpha, IL-6, and IL-8 corresponded to the occupation of high- or low-affinity receptors, respectively.
5990 17785828 Mo-DCs matured by IFN-gamma and NadADelta351-405 supported the proliferation of naive CD4+ T lymphocytes, inducing the differentiation of both IFN-gamma and IL-4 producing phenotypes.
5991 17850587 Antigen (Ag)-presenting and co-stimulatory capacity of neonatal B-cells was evaluated by staining for major histocompatibility complex (MHC)II, CD80, CD86 and CD40.
5992 17850587 Spleen cells from mice receiving LT-K63 showed enhanced proliferation and interferon (IFN)-gamma, interleukin (IL)-4, IL-5 and IL-10 secretion upon TT stimulation, whereas cells from mice receiving CpG2006 could only enhance IL-10 secretion.
5993 17850592 T-cell response to cytomegalovirus (CMV), varicella zoster virus (VZV) and tetanus toxoid (TT) was determined by flow cytometry analysis for CD69, TNFalpha, IFNgamma, IL-4 expression and cell proliferation.
5994 17850592 In spite of a general reduction of the CD4/CD8 ratio following transplantation, recovery of antigen specific CD4(+) T cells reactivity generally occurred prior to CD8(+) recovery and often to a higher level.
5995 17855518 We therefore tested recombinant RSV (rRSV) candidates expressing prototypic murine Th1 (gamma interferon [IFN-gamma]) or Th2 (interleukin-4 [IL-4]) cytokines, with detailed monitoring of responses to subsequent infections with RSV or (as a control) influenza A virus.
5996 17855518 Although priming with either recombinant vector reduced viral load during RSV challenge, enhanced weight loss and enhanced pulmonary influx of RSV-specific CD8+ T cells were observed after challenge in mice primed with rRSV/IFN-gamma.
5997 17868957 Experiments were conducted to investigate the effect of a fusion gene of porcine IL-4 and IL-6 (PIL4/IL6) packaged with chitosan nanoparticles (CNPs) in terms of the development of a novel effective adjuvant.
5998 17868957 Furthermore, the levels of IL-2, IL-4 and IL-6 increased remarkably in the sera of immunized mice (P<0.05).
5999 17868957 Experiments were conducted to investigate the effect of a fusion gene of porcine IL-4 and IL-6 (PIL4/IL6) packaged with chitosan nanoparticles (CNPs) in terms of the development of a novel effective adjuvant.
6000 17868957 Furthermore, the levels of IL-2, IL-4 and IL-6 increased remarkably in the sera of immunized mice (P<0.05).
6001 17886372 Suppression of APF was observed along with suppression of proinflammatory cytokines (IL-1beta, IL-6, TNF-alpha) as well as B-lymphocytes growth factor (IL-4).
6002 17905435 The secretion level of IFN-gamma was much higher than that of IL-4 in vAc-N or vAc-S immunized groups, suggesting a strong Th1 bias towards cellular immune responses.
6003 17908806 Hybrid cell vaccination resolves Leishmania donovani infection by eliciting a strong CD8+ cytotoxic T-lymphocyte response with concomitant suppression of interleukin-10 (IL-10) but not IL-4 or IL-13.
6004 17908806 Moreover, splenic lymphocytes of HCV-treated mice not only showed the enhancement of gamma interferon but also marked an elevated expression of the Th2 cytokines interleukin-4 (IL-4) and IL-13 at both transcriptional and translational levels.
6005 17908806 Interestingly, CD8+ T-cell depletion completely abrogated HCV-induced immunity, resulting in a marked increase of IL-10 but not of IL-4 and IL-13.
6006 17908806 Hybrid cell vaccination resolves Leishmania donovani infection by eliciting a strong CD8+ cytotoxic T-lymphocyte response with concomitant suppression of interleukin-10 (IL-10) but not IL-4 or IL-13.
6007 17908806 Moreover, splenic lymphocytes of HCV-treated mice not only showed the enhancement of gamma interferon but also marked an elevated expression of the Th2 cytokines interleukin-4 (IL-4) and IL-13 at both transcriptional and translational levels.
6008 17908806 Interestingly, CD8+ T-cell depletion completely abrogated HCV-induced immunity, resulting in a marked increase of IL-10 but not of IL-4 and IL-13.
6009 17908806 Hybrid cell vaccination resolves Leishmania donovani infection by eliciting a strong CD8+ cytotoxic T-lymphocyte response with concomitant suppression of interleukin-10 (IL-10) but not IL-4 or IL-13.
6010 17908806 Moreover, splenic lymphocytes of HCV-treated mice not only showed the enhancement of gamma interferon but also marked an elevated expression of the Th2 cytokines interleukin-4 (IL-4) and IL-13 at both transcriptional and translational levels.
6011 17908806 Interestingly, CD8+ T-cell depletion completely abrogated HCV-induced immunity, resulting in a marked increase of IL-10 but not of IL-4 and IL-13.
6012 17917970 CD14(+) cells were cultured in the presence of GM-CSF and IL-4.
6013 17919443 We observed that this vaccine caused a significant reduction in parasite load in liver and spleen and induced a high production of IFN-gamma and IL-4 by spleen cells from vaccinated mice in response to Leishmania antigen.
6014 17929411 In the study, concentrations of IFN-gamma/Il-2 and 1l-4/Il-5 in supernatants of cultured mice splenocytes have been determined to evaluate differences in Th1 or Th2 lymphocytes subpopulation response.
6015 17929411 Simultaneously, studies of intracellular expression of genes encoding of Il-2, Il-12, IFN-gamma and Il-4, Il-5, Il-10, Il-13 in mice splenocytes, and genes encoding factors involved in inflammatory process in the lung tissue (GM-CSF, TNF-alpha, Il-1beta, Il-6 i TGF-beta) have been performed on RNA level.
6016 17931755 Positive prognostic indicators associated with reduced pathology in the BCG-vaccinated group were decreased antigen induced IFN-gamma, iNOS, IL-4, and MIP1-alpha responses, increased antigen induced FoxP3 expression, and a diminished activation phenotype (i.e., downward arrow CD25+ and CD44+ cells and upward arrow CD62L+ cells) in mycobacterial-stimulated mononuclear cell cultures.
6017 17942922 We have observed that 42 of 70 (60%) tumor samples from patients with PDA express moderate- to high-density surface IL-4 receptor (IL-4R), whereas normal pancreatic samples express no or low-density IL-4R.
6018 17951990 Leishmanin skin test (LST) response, proliferative response of lymphocyte (PRL) to L. major antigen, IFN-gamma and IL-4 production, and percentage of L. major-specific CD4+, CD8+ and CD16+/CD56+ cells in peripheral blood mononuclear cells were assessed.
6019 17959278 The blood was weekly collected to detect the change of IgG, IgA, IgM, specific antibody, IL-2, IL-4 and IL-6 by ELISA.
6020 17977633 Subcutaneous immunization with a mixture of HA vaccine and gamma-PGA-NPs induced higher mononuclear cell proliferation and the production of gamma-interferon (IFN-gamma), interleukin (IL)-4, and IL-6 upon HA restimulation, and enhanced not only anti-HA neutralizing antibody production but also the influenza virus-specific cell-mediated immune response, including CTL activity, compared with immunization with HA alone or a mixture of HA and aluminum adjuvant.
6021 17978011 We used a multiplex, suspension-array-based immunoassay method to measure 10 proinflammatory (interleukin-1beta [IL-1beta], IL-6, and IL-8) and immunoregulatory (gamma interferon [IFN-gamma], IL-2, IL-4, IL-5, IL-10, IL-12, and IL-13) cytokines in cervical mucus specimens collected via ophthalmic sponge from 72 healthy, nonpregnant women and correlate their levels with biologic and behavioral covariates in a cross-sectional design.
6022 17978011 Among the covariates examined, the most striking finding was the significant (P < or = 0.05) association between depressed levels of the cytokines IFN-gamma, IL-1beta, IL-6, and IL-10 and cigarette smoking.
6023 17980939 Immune responses of two recombinant adenoviruses expressing VP1 antigens of FMDV fused with porcine granulocyte macrophage colony-stimulating factor.
6024 17980939 In the present report, we constructed and characterized the immune responses conferred by two recombinant adenoviruses expressing VP1 epitopes (three amino acid residues 21-60, 141-160 and 200-213 in VP1, designated VPe) or VP1 protein of FMDV fused with porcine granulocyte macrophage colony-stimulating factor (named rAd-GMCSF-VPe and rAd-GMCSF-VP1).
6025 17980939 The results showed that the highest levels of FMDV-specific T cell proliferation, IFN-gamma and IL-4 could be induced by rAd-GMCSF-VPe expressing fusion GMCSF-VPe, and the highest level of FMDV-specific humoral immune responses could be induced by rAd-GMCSF-VP1 expressing fusion GMCSF-VP1 in mice.
6026 17996993 In contrast, the vaccine powder delivered by the pulmonary route, induced not only systemic humoral (IgG) responses, but also cell-mediated (Il-4, IFN-gamma) and mucosal immune responses (IgA, IgG).
6027 17996992 Antigenic stimulation of peripheral blood CD4+ T cells from BCG-vaccinated cattle enhanced expression of perforin and IFNgamma in cells expressing a CD45RA-CD45RO+CD62L+ cell surface phenotype, enhanced transcription of granulysin, IFNgamma, perforin, IL-4, IL-13, and IL-21, and enhanced anti-mycobacterial activity of CD4+ T cells against BCG-infected macrophages.
6028 17998917 Single oral immunization with live BCG also invoked an interleukin-2 response (but not TNF-alpha or IL-4), although the magnitude was not elevated by multiple immunizations.
6029 18003817 The cytokines analyzed in this study were gamma interferon, vascular endothelial growth factor, tumor necrosis factor alpha, interleukin-6 (IL-6), macrophage inflammatory protein 1beta, monocyte chemoattractant protein 1, IL-12p40, and IL-4.
6030 18006850 The immune responses elicited in transgenic mice comprised the activation of lung granulocytes and macrophages and of systemic adaptive responses based on helper T cells and their cytokines (IFN-gamma and IL-4) and anti-HER-2/neu antibodies.
6031 18024219 There was a significant increase in lymphocyte proliferation, interleukin-4 and interferon-gamma levels in cells isolated from immunized mice as compared to control.
6032 18024909 There was more significant lung inflammation associated with eosinophilic infiltration, as well as increased levels of interleukin-4 (IL-4) and IL-5, in the bronchoalveolar lavages of mice immunized with hMPV alone or with the adjuvant.
6033 18054415 Allergen immunotherapy in intermittent allergic rhinitis reduces the intracellular expression of IL-4 by CD8+ T cells.
6034 18056374 Interaction between GATA-3 and the transcriptional coregulator Pias1 is important for the regulation of Th2 immune responses.
6035 18056374 Here, we reported a number of GATA-3 associated proteins in Th2 cells, and one of such proteins Pias1 functioned as a positive transcriptional coregulator for GATA-3.
6036 18056374 When overexpressed in Th2 cells, Pias1 enhanced the expression of IL-13, and to lesser degrees, IL-4 and -5.
6037 18056374 In Leishmania major infection, manipulating Pias1 expression in parasite-reactive CD4 T cells altered severity of disease caused by Th2 responses.
6038 18056374 Mechanistically, Pias1 markedly potentiated GATA-3-mediated activation of the IL-13 promoter by facilitating the recruitment of GATA-3 to the promoter.
6039 18056374 In contrast, IL-5 promoter was modestly enhanced by Pias1 and no effect was observed on IL-4 promoter.
6040 18056374 Interaction between GATA-3 and the transcriptional coregulator Pias1 is important for the regulation of Th2 immune responses.
6041 18056374 Here, we reported a number of GATA-3 associated proteins in Th2 cells, and one of such proteins Pias1 functioned as a positive transcriptional coregulator for GATA-3.
6042 18056374 When overexpressed in Th2 cells, Pias1 enhanced the expression of IL-13, and to lesser degrees, IL-4 and -5.
6043 18056374 In Leishmania major infection, manipulating Pias1 expression in parasite-reactive CD4 T cells altered severity of disease caused by Th2 responses.
6044 18056374 Mechanistically, Pias1 markedly potentiated GATA-3-mediated activation of the IL-13 promoter by facilitating the recruitment of GATA-3 to the promoter.
6045 18056374 In contrast, IL-5 promoter was modestly enhanced by Pias1 and no effect was observed on IL-4 promoter.
6046 18063448 The proliferation of peripheral blood mononuclear cells (PBMCs), IFN-gamma and IL-4 in serum, and the titre of IgG, IgG2/IgG1 isotype in serum and IgA in intestinal washings and feces to PRV vaccine were tested at different time-points.
6047 18068331 Low Sociable animals also showed alterations in lymph node expression of the immunoregulatory cytokine genes IFNG and IL4, and lower secondary IgG responses to tetanus vaccination.
6048 18083279 Outstanding IFN-gamma/IL-4 ratio besides low levels of IgG1 with subsequent high IgG2a/IgG1 ratio further characterized a Type-1 polarized immunological profile in pcDNA-IL-12-vaccinated animals.
6049 18086017 Exudates of rats vaccinated with Na-ASP-2 showed an increase of cytokines such as IL-4, IL-10, IFN-gamma and especially, IL-5, as well as IgG1 and IgG2 antibodies.
6050 18094185 Interestingly, neither gamma interferon- nor interleukin-4-producing CD4 T cells directed to I-E(d)-restricted epitope were detected in the lungs of rAd/3xG-immune mice upon challenge, whereas priming with vaccinia virus expressing RSV G (vvG) elicited strong Th1/Th2 mixed CD4 T-cell responses.
6051 18097046 Suppression of lethal Plasmodium yoelii malaria following protective immunization requires antibody-, IL-4-, and IFN-gamma-dependent responses induced by vaccination and/or challenge infection.
6052 18097046 Studies with cytokine-deficient mice showed that protection was induced by immunization of C57BL/6 mice only when IL-4 and IFN-gamma were both present.
6053 18097046 In BALB/c mice, the absence of either IL-4 or IFN-gamma led to predictable shifts in the IgG isotype profile but did not reduce the magnitude of the Ab response induced by rPyMSP-8 immunization.
6054 18097046 Combined, the data indicate that induction of protective responses by merozoite surface protein-based vaccines depends on IL-4 and IFN-gamma-dependent pathways and that vaccine efficacy is significantly influenced by host responses elicited upon infection.

6066 18097046 Combined, the data indicate that induction of protective responses by merozoite surface protein-based vaccines depends on IL-4 and IFN-gamma-dependent pathways and that vaccine efficacy is significantly influenced by host responses elicited upon infection.
6067 18156796 After immunization of mice with HPV16 L1 VLPs, we measured splenocytes proliferation and the levels of IFNgamma, IL2, IL4, and IL5.
6068 18158729 Monocyte-derived DCs from healthy donors were infected with the recombinant adenovirus (Ad) harboring HCV NS3 (AdNS3), NS4 (NS4A and NS4B; AdNS4), NS5 (NS5A and NS5B; AdNS5), NS3/NS4 (AdNS3/NS4), and NS4/NS5 (AdNS4/NS5) genes, and then used to stimulate autologous lymphocytes in vitro.
6069 18158729 Antigen-specific cellular immune responses were detected by interferon-gamma (IFN-gamma), interleukin 4 (IL-4), and Granzyme B (GrB) enzyme-linked immunospot assays (ELISPOT).
6070 18158729 DCs transduced with NS3/NS4 or NS4/NS5 had similar ability to elicit specific immune responses to HCV.
6071 18162346 The analysis of the cytokine profile from spleen cells revealed that BSA-microparticles induced the secretion of both interferon-gamma (IFN-gamma) and interleukin-4 (IL-4).
6072 18164561 Both vaccines were able to induce a non-significant secretion of gamma interferon and did not induce the secretion of IL-4 or tumor necrosis factor (TNF)-alpha.
6073 18164706 After B. microti infection, the levels of interleukin (IL)-2, IL-4, IL-5, IL-10, IL-12p70, and tumor necrosis factor (TNF)-alpha in the treated group were significantly lower than in the control group.
6074 18191231 The effect was determined in the form of protective anti-JEV E titers, antibodies (IgG1 and IgG2a), spleen cell lymphocyte proliferation, the levels of interferon-gamma and interleukin-4 cytokines, and the T-lymphocyte sub-type composition.
6075 18191231 The IgG2a titer and interferon-gamma level suggested that the E-BD protein potentiates the Th1 immune response.
6076 18191307 Specific antibodies in serum and cytokines (IL-2, IL-4 and IFN-gamma) from splenocytes were detected by indirect ELISA.
6077 18191308 PLG formulation greatly reduced lung eosinophilia and prevented the induction of IL-4 and IL-5 during challenge, accompanied by a less marked CD4+ T cell response and a restoration of the CD8+ T cell recruitment seen during infection of non-vaccinated animals.
6078 18191311 High titers of IgG1 and IgG2b were detected as well as production of IL-4, IL-10, IL-12 and INF-gamma in response to Nlac PorB, consistent with induction of both a Th1-type and a Th2-type immune response.
6079 18202753 Recently, we have demonstrated up-regulation of a new member of the LOX family, lysyl oxidase-like 4 (LOXL4), in invasive HNC revealed a significant correlation between LOXL4 expression and local lymph node metastases and higher tumour stages.
6080 18202753 The successfully transfected immature dendritic cells (DCs) were induced to mature with GM-CSF, IL-4, IL-1beta, TNF-alpha, IL-6, and PGE2, and then used to stimulate T cell enriched non-adherent fraction of PBMC.
6081 18202753 LOXL4 specific T cell stimulation induced cytotoxic T lymphocyte (CTL) response was monitored using IFN-gamma secretion from the non-adherent PBMC fraction exposed to mature, LOXL4 transfected DCs acting as the antigen presenting target cells.
6082 18245488 Our results show the induction of an immune response against a newly defined PSCA epitope that is mediated primarily by CD8 T cells.
6083 18245488 The prostates of PSCA-vaccinated mice were infiltrated by CD4-positive, CD8-positive, CD11b-positive, and CD11c-positive cells.
6084 18245488 Vaccination induced MHC class I expression and cytokine production [IFN-gamma, tumor necrosis factor-alpha, interleukin 2 (IL-2), IL-4, and IL-5] within prostate tumors.
6085 18271251 Western blot showed that the expression product (SP(Usp45)-INS protein) targeted mainly at the cell wall while little was found in cytoplasm or supernatant.
6086 18271251 ELISA and Western blot results showed that the recombinant strain could induce SP(Usp45)-INS-specific antibodies and raise IL-4 level (38.583 +/- 2.083 pg/mL, P < 0.05) in the mice' s sera.
6087 18279956 The blood was weekly collected from mice after vaccination to detect the changes of immunoglobulins, specific antibodies, IL-2, IL-4, IL-6 and immune cells. 28 days after vaccination, the mice were orally challenged with virulent Pasteurella multocida.
6088 18292584 Ex vivo stimulation of whole blood with BCG for 12 h induced expression of predominantly IFN-gamma, IL-2, and TNF-alpha in CD4+ T cells in seven distinct cytokine combinations.
6089 18292584 IL-4 and IL-10 expression was detected in CD4+ T cells at low frequencies and only in cells that did not coexpress type 1 cytokines.
6090 18292584 Specific CD8+ T cells were less frequent than CD4+ T cells and produced mainly IFN-gamma and/or IL-2 and less TNF-alpha, IL-4, and IL-10.
6091 18292584 Importantly, many mycobacteria-specific CD4+ and CD8+ T cells did not produce IFN-gamma.
6092 18292584 Among five phenotypic patterns of CD4+ T cells, central memory cells were more likely to be IL-2+ and effector cells were more likely to be IFN-gamma+.
6093 18292584 Ex vivo stimulation of whole blood with BCG for 12 h induced expression of predominantly IFN-gamma, IL-2, and TNF-alpha in CD4+ T cells in seven distinct cytokine combinations.
6094 18292584 IL-4 and IL-10 expression was detected in CD4+ T cells at low frequencies and only in cells that did not coexpress type 1 cytokines.
6095 18292584 Specific CD8+ T cells were less frequent than CD4+ T cells and produced mainly IFN-gamma and/or IL-2 and less TNF-alpha, IL-4, and IL-10.
6096 18292584 Importantly, many mycobacteria-specific CD4+ and CD8+ T cells did not produce IFN-gamma.
6097 18292584 Among five phenotypic patterns of CD4+ T cells, central memory cells were more likely to be IL-2+ and effector cells were more likely to be IFN-gamma+.
6098 18299268 Interleukin-21 (IL-21) is a newly described, typical, four-helix cytokine showing significant homology with IL-2, IL-4 and IL-15.
6099 18299268 Prevalence and level of IL-21, total IgG and subclass (IgG1, IgG2, IgG3 and IgG4) titers were determined in plasma by enzyme-linked immunosorbent assay (ELISA).
6100 18299268 Plasma IL-21 levels correlated with IgG1 and IgG3 levels.
6101 18299268 Additionally, plasma IL-21 levels correlated with hemoglobin levels in younger children and with parasite density.
6102 18299268 Here we describe the relationship between IL-21 and antibodies for erythrocyte-binding antigen-175 (EBA-175) peptide 4, a malaria vaccine candidate in Gabonese children with acute falciparum malaria.
6103 18300038 Very little interleukin-4 (IL-4) was released by cells from mice immunized with PIMs and OVA, whereas cells from animals immunized with complete Freund's adjuvant (CFA) and OVA released IL-4 as well as IFN-gamma.
6104 18314558 The vaccine response of aged animals was characterized by a 6-fold increase in interleukin-4 and a 3-fold increase in interferon-gamma (IFN-gamma) secreting cells, whereas in young animals immunization only stimulated the production of the type 1 cytokine IFN-gamma.
6105 18319583 The results revealed that IFN-gamma and IL-6 were upregulated during the first week post-vaccination.
6106 18319583 Low level expressions of IL-1alpha, IL-1beta, TNFalpha and IL-10 and no expression of IL-2 and IL-4 were observed compared with the control camels.
6107 18321614 HSP-70 and PFR-2 also produced an increase of the TNF-alpha transcripts abundance.
6108 18321614 No measurable induction of IL-10 was observed and low levels of IL-4 mRNA were produced in response to the three mentioned recombinant antigens.
6109 18325643 Specific SNPs in the TLR 2, 3, 4, 5, 6, MyD88 and MD2 genes were associated with measles-specific humoral and cellular immunity.
6110 18325643 Heterozygous variants for rs4986790 (Gly299Asp) and rs4986791 (Ile399Thr) in the TLR4 gene demonstrated higher levels of (p <or= 0.02) IL-4 secretion.
6111 18325643 Heterozygous variants for SNPs in TLR5 (rs5744174) and TLR6 (rs5743818) were associated with higher levels of (p <or= 0.02) IFN-gamma secretion.
6112 18325643 In addition, SNPs in MyD88 and MD2, intracellular molecules that associate with TLRs, also demonstrated associations with variations in antibody and IL-10 production (p <or= 0.03).
6113 18329193 Because cytokines play a key role in immunity, the expression levels of TGF-beta, IFN-gamma, IL-4 and IL-6 were measured, by RT-PCR in the spleen, the ileum and the mesenteric lymph node of the animals at the end of the experiment.
6114 18329193 In the mesenteric lymph node, a significantly lower expression of both TGF-beta and IFN-gamma mRNA expression levels is observed in animals feed with DON when compared with control piglets.
6115 18329759 The splenocytes collected from the VLP-immunized mice exhibited significant cell proliferation and produced high levels of IFN-gamma, IL-2 and IL-4 after stimulation, indicating the induction of Th1 and Th2 immune responses by VLP immunization.
6116 18343889 Accordingly, depletion of IL-4 or Gr1+ cells in alum-injected mice had no effect on the ability of alum to improve expansion of primary CD4 T cells.
6117 18343889 These data suggest that alum affects the immune response in at least two ways: one, independent of Gr1+ cells and IL-4, that promotes CD4 T cell proliferation and another, via Gr1+IL-4+ cells, that participates in the polarization of the response.
6118 18343889 Accordingly, depletion of IL-4 or Gr1+ cells in alum-injected mice had no effect on the ability of alum to improve expansion of primary CD4 T cells.
6119 18343889 These data suggest that alum affects the immune response in at least two ways: one, independent of Gr1+ cells and IL-4, that promotes CD4 T cell proliferation and another, via Gr1+IL-4+ cells, that participates in the polarization of the response.
6120 18353921 Vaccination with the DNA construct generated a good cellular immune response with significant increases in gamma interferon and interleukin-2 (IL-2) cytokine levels (Th1), but no increase in IL-4 levels (Th2).
6121 18362129 Cytokine secretion from spleen cells of mice vaccinated with the encapsulated vjbR::Tn5 revealed elevated secretion of gamma interferon and interleukin-12, but no interleukin-4, suggesting an induction of a T helper 1 response reflecting the enhanced immunity associated with microencapsulation.
6122 18378159 Thus, we have analyzed two T(H)1/T(H)2 signature cytokines (IFN-gamma and IL-4) from 12 healthy first-time adults vaccinated with YF17DD virus.
6123 18405984 In addition, induction of IFNgamma, IL4, IL10, IL12 secretion in presence of GSPL was investigated in PBMC from normal individuals.
6124 18405984 ROS and RNI in addition to IFNgamma and IL12 were induced by GSPL.
6125 18419471 In contrast, CD3(+), CD4(+), or CD8(+) T lymphocytes from immunized animals transferred protection, and the vaccine was efficacious in IL-4-deficient mice but not in IFN-gamma-deficient mice.
6126 18435687 Although both Th1 (IFN-gamma, TNF-alpha and IL-12) and Th2 (IL-4 and IL-10) cytokines were secreted by the PBMCs of the P. vivax-exposed individuals in response to PvTRAg, the overall response was more inclined towards Th2.
6127 18442785 Also, exposure of DCs to EP54 (50 microg/ml) induced the activation of genes specific for the Th1 cytokines IL-6, IL-12, INFgamma, and TNFalpha as well as the Th2 cytokine IL-4.
6128 18462845 The effects of IL-6 and TNF-alpha as molecular adjuvants on immune responses to FMDV and maturation of dendritic cells by DNA vaccination.
6129 18462845 In this study, we investigated whether co-inoculation of a construct expressing either IL-6 or TNF-alpha as the molecular adjuvant with FMDV DNA vaccine, pcD-VP1, can increase immune responses.
6130 18462845 Compared to the group immunized with pcD-VP1 alone, the co-inoculation with either molecular adjuvant induced a higher ratio of IgG2a/IgG1, higher levels of expression of IFN-gamma in CD4+ and CD8+ T cells, IL-4 in CD4+ T cells, and in vivo antigen-specific cytotoxic response.
6131 18462845 Together, the results demonstrate that IL-6 and TNF-alpha used as molecular adjuvants can enhance the antigen-specific cell-mediated responses elicited by VP1 DNA vaccine.
6132 18468738 Moreover, mice receiving RT-ODCsig gene mounted a mixed Th1/Th2 response characterized by the in vitro secretion of IFN-gamma, IL-2, TNF-alpha, IL-4, and IL-10 upon stimulation of splenocytes with RT protein or RT derived peptides.
6133 18481222 The secretion of Th type 1 (TNF, IFN-gamma and IL-2) and Th type 2 (IL-4 and IL-6) cytokines was tested in the medium fluid of purified PBL and splenocyte cultures; their absolute values were expressed in relative indexes.
6134 18481222 The PBL from FpgD1/313 immunized mice showed increased secretion of both T(H)1 (TNF) as well as T(H)2 (IL-4) cytokines (7-10-fold, respectively).
6135 18481222 The secretion of Th type 1 (TNF, IFN-gamma and IL-2) and Th type 2 (IL-4 and IL-6) cytokines was tested in the medium fluid of purified PBL and splenocyte cultures; their absolute values were expressed in relative indexes.
6136 18481222 The PBL from FpgD1/313 immunized mice showed increased secretion of both T(H)1 (TNF) as well as T(H)2 (IL-4) cytokines (7-10-fold, respectively).
6137 18486913 Accordingly, the potency and adjuvanticity of eight adjuvant formulations based on Montanide ISA720, MF59, monophosphoryl lipid A (MPL), QS21 (saponin derivative), MPL-SE (stable emulsion of a MPL derivative), and MPL-AF (MPL in aqueous formulation) were studied in immune gene knockout mice, IFN-gamma -/-, IL-4 -/-, and STAT6 -/-, using the P. falciparum MSP1 vaccine, P30P2MSP1-19 as a model immunogen.
6138 18502198 In addition, CIM significantly promotes an elevated level of IL-4 and IFN-gamma in antigen-specific CD4(+) T cells and a robust antigen-specific cytotoxic response in the animals immunized with pcD-S2 plus CIM.
6139 18502198 Further, CIM induces pro-inflammatory cytokine expression such as the IL-12 and down-regulates anti-inflammatory cytokine expression such as IL-10 and TGF-beta, which may lead to an impairment of CD4(+)CD25(+) Treg cell-mediated suppression.
6140 18519743 Pulmonary eosinophilia requires interleukin-5, eotaxin-1, and CD4+ T cells in mice immunized with respiratory syncytial virus G glycoprotein.
6141 18519743 We have shown IL-4 and IL-13 activity must be simultaneously inhibited to reduce disease severity.
6142 18519743 We now address the contributions of IL-5, eotaxin-1, and CD4+ and CD8+ T cells to the induction of disease-enhancing immune responses.
6143 18519743 Depletion of CD4+ T cells during immunization prevented IL-4, IL-13, and eotaxin-1 production, diminished eosinophilia, and reduced weight loss.
6144 18519743 Conversely, CD8+ T cell depletion did not decrease eosinophilia, weight loss, or type 2 cytokines but did dramatically reduce mucus production and increase eotaxin production.
6145 18519743 We conclude CD4+ T cell production of IL-5 and induction of eotaxin-1 are required for vvGs-induced eosinophilia following RSV challenge, while CD8+ T cells appear to down-regulate eotaxin-1 and mucus production.
6146 18519743 Pulmonary eosinophilia requires interleukin-5, eotaxin-1, and CD4+ T cells in mice immunized with respiratory syncytial virus G glycoprotein.
6147 18519743 We have shown IL-4 and IL-13 activity must be simultaneously inhibited to reduce disease severity.
6148 18519743 We now address the contributions of IL-5, eotaxin-1, and CD4+ and CD8+ T cells to the induction of disease-enhancing immune responses.
6149 18519743 Depletion of CD4+ T cells during immunization prevented IL-4, IL-13, and eotaxin-1 production, diminished eosinophilia, and reduced weight loss.
6150 18519743 Conversely, CD8+ T cell depletion did not decrease eosinophilia, weight loss, or type 2 cytokines but did dramatically reduce mucus production and increase eotaxin production.
6151 18519743 We conclude CD4+ T cell production of IL-5 and induction of eotaxin-1 are required for vvGs-induced eosinophilia following RSV challenge, while CD8+ T cells appear to down-regulate eotaxin-1 and mucus production.
6152 18523277 Previously, we showed that nasal administration of a naked cDNA plasmid expressing Flt3 ligand (FL) cDNA (pFL) enhanced CD4(+) Th2-type, cytokine-mediated mucosal immunity and increased lymphoid-type dendritic cell (DC) numbers.
6153 18523277 Nasal immunization of mice with OVA plus Ad-FL as mucosal adjuvant elicited high levels of OVA-specific Ab responses in external secretions and plasma as well as significant levels of OVA-specific CD4(+) T cell proliferative responses and OVA-induced IFN-gamma and IL-4 production in NALT, cervical lymph nodes, and spleen.
6154 18523277 Notably, the number of CD11b(+)CD11c(+) DCs expressing high levels of costimulatory molecules was preferentially increased.
6155 18523277 Taken together, these results suggest that the use of Ad-FL as a nasal adjuvant preferentially induces mature-type NALT CD11b(+)CD11c(+) DCs that migrate to effector sites for subsequent CD4(+) Th1- and Th2-type cytokine-mediated, Ag-specific Ab and CTL responses.
6156 18523296 The central memory CD4+ T cell population generated during Leishmania major infection requires IL-12 to produce IFN-gamma.
6157 18523296 In this study, we show that the Leishmania-specific central memory CD4(+) T cells require IL-12 to produce IFN-gamma, demonstrating that this population needs additional signals to develop into Th1 cells.
6158 18523296 In addition, we found that when central memory CD4(+) T cells were adoptively transferred into IL-12-deficient hosts, many of the cells became IL-4 producers.
6159 18523314 Additionally, anti-OVA specific IgE and production of IL-4 and IL-5 of T cells stimulated by OVA were significantly decreased in CD40 siRNA-treated mice.
6160 18524884 Infant monkeys developed sustained neutralizing antibody and T cells secreting IFN-gamma and interleukin-4.
6161 18528294 The vaccine consisted of autologous DCs obtained from peripheral blood mononuclear cells (PBMCs) cultured in granulocyte macrophage-colony stimulating factor and IL-4 then pulsed with autologous tumor cell lysate and keyhole limpet hemocyanin (KLH).
6162 18549446 However, interleukin (IL)-4 and IL-5 secretion were enhanced only in spleen and lymph node cells from neonatally primed mice.
6163 18550809 This B cell response is absent in CD1d(-/-) and Jalpha18(-/-) mice but not CD4(-/-) mice.
6164 18550809 The antibody response to NP-alphaGalCer is dominated by the IgM, IgG3, and IgG2c isotypes, and marginal zone B cells stimulate better in vitro lipid antigen-driven proliferation than follicular B cells, suggesting an important role for this B cell subset. iNK T cell help for B cells is shown to involve cognate help from CD1d-instructed lipid-specific iNK T cells, with help provided via CD40L, B7-1/B7-2, and IFN-gamma, but not IL-4.
6165 18552348 For example, aspartylglucosaminidase (AGA), PLA2, SIAT8B, GALNT7, or B3GAT1 metabolize chemical ligands to which the influenza virus, herpes simplex, cytomegalovirus (CMV), rubella, or Toxoplasma gondii bind.
6166 18552348 The epidermal growth factor receptor (EGR/EGFR) is used by the CMV to gain entry to cells, and a CMV gene codes for an interleukin (IL-10) mimic that binds the host cognate receptor, IL10R.
6167 18552348 The fibroblast growth factor receptor (FGFR1) is used by herpes simplex.
6168 18552348 KPNA3 and RANBP5 control the nuclear import of the influenza virus.
6169 18552348 Disrupted in schizophrenia 1 (DISC1) controls the microtubule network that is used by viruses as a route to the nucleus, while DTNBP1, MUTED, and BLOC1S3 regulate endosomal to lysosomal routing that is also important in viral traffic.
6170 18552348 Neuregulin 1 activates ERBB receptors releasing a factor, EBP1, known to inhibit the influenza virus transcriptase.
6171 18552348 Other viral or bacterial components bind to genes or proteins encoded by CALR, FEZ1, FYN, HSPA1B, IL2, HTR2A, KPNA3, MED12, MED15, MICB, NQO2, PAX6, PIK3C3, RANBP5, or TP53, while the cerebral infectivity of the herpes simplex virus is modified by Apolipoprotein E (APOE).
6172 18552348 Genes encoding for proteins related to the innate immune response, including cytokine related (CCR5, CSF2RA, CSF2RB, IL1B, IL1RN, IL2, IL3, IL3RA, IL4, IL10, IL10RA, IL18RAP, lymphotoxin-alpha, tumor necrosis factor alpha [TNF]), human leukocyte antigen (HLA) antigens (HLA-A10, HLA-B, HLA-DRB1), and genes involved in antigen processing (angiotensin-converting enzyme and tripeptidyl peptidase 2) are all concerned with defense against invading pathogens.
6173 18552348 Human microRNAs (Hsa-mir-198 and Hsa-mir-206) are predicted to bind to influenza, rubella, or poliovirus genes.
6174 18563891 A number of cyclic analogues were tested for their ability to inhibit (antagonize) Th1 (IFN-gamma) responses, and cyclo(83-99)[A (91)]MBP 83-99 mutant peptide was found to be the most efficient inhibitor.
6175 18563891 We demonstrated that cyclo(83-99)[A (91)]MBP 83-99 peptide emulsified in CFA enhanced Th2 (IL-4) and antibody responses in vivo.
6176 18563891 Moreover, immunization of mice with antagonist cyclo(83-99)[A (91)]MBP 83-99 peptide conjugated to reduced mannan enhanced IL-4 responses compared to cyclo(83-99)MBP 83-99 peptide.

6180 18566382 Coligation of the hepatitis C virus receptor CD81 with CD28 primes naive T lymphocytes to acquire type 2 effector function.
6181 18566382 In this study, we describe for the first time that coligation of the tetraspanins CD81, CD82, or CD9 with the costimulatory molecule CD28 in vitro leads to proliferation of naive T cells.
6182 18566382 When activated through this pathway, both CD4+ and CD8+ naive T cells differentiate into type 2 effector cells, which produce IL-4, IL-5, IL-13, and IL-10, together with IL-2 and TNF-alpha, but little to no IFN-gamma.
6183 18566382 These effector cells descend from precursors that display early and strong production of IL-4, STAT6 phosphorylation, and up-regulation of the transcription factor GATA-3, suggesting a direct skewing toward Th2 differentiation without a Th0 intermediate.
6184 18566382 The hepatitis C virus envelope protein E2 is the only ligand known for CD81.

6190 18566640 Immunostaining and confocal microscopy revealed hepatic accumulation of IFNgamma+ Th1 and IL-4+ Th2 cells in animals from groups II and IV, respectively.
6191 18569071 We investigated if ELISpot, measuring cytokine production at the single cell level, facilitated a better detection of the Th2 cytokines IL-4 and IL-5.
6192 18569071 The low IL-5 response to TT was associated with a higher induction of the down-regulatory cytokine IL-10 by TT as compared to nickel (p < 0.001).
6193 18569071 Overall, ELISpot displayed a better detection of IL-4 as well as low intensity IL-5 responses thus emphasizing the importance of selecting suitable methods for the measurement of cytokine production ex vivo.

6197 18573897 In addition, testing of TB patients' PBMC for secretion of proinflammatory cytokines (tumor necrosis factor alpha [TNF-alpha], interleukin 6 [IL-6], IL-8, and IL-1beta), Th1 cytokines (IFN-gamma, IL-2, and TNF-beta), and Th2 cytokines (IL-4, IL-5, and IL-10) showed differential effects of RD peptides in the secretion of IFN-gamma and IL-10, with high IFN-gamma/IL-10 ratios (32 to 5.0) in response to RD1, RD5, RD7, RD9, and RD10 and low IFN-gamma/IL-10 ratios (<1.0) in response to RD12, RD13, and RD15.
6198 18573897 In conclusion, our results suggest that M. tuberculosis RDs can be divided into two major groups--one group that activates PBMC to preferentially secrete IFN-gamma and another group that activates preferential secretion of IL-10--and that these two groups of RDs may have roles in protection against and pathogenesis of TB, respectively.
6199 18579264 The stimulated T cells produced higher amount of IL-4 and IL-10 than IFN-gamma, TNF-alpha, and IL-12 indicating a Th2 type of response bias.
6200 18579694 Differential expression of interleukin-4 (IL-4) and IL-4 delta 2 mRNA, but not transforming growth factor beta (TGF-beta), TGF-beta RII, Foxp3, gamma interferon, T-bet, or GATA-3 mRNA, in patients with fast and slow responses to antituberculosis treatment.
6201 18579694 This study investigated interleukin-4 (IL-4), IL-4 delta 2, transforming growth factor beta (TGF-beta), TGF-beta RII, Foxp3, GATA-3, T-bet, and gamma interferon (IFN-gamma) transcription in peripheral blood samples of adult pulmonary tuberculosis patients prior to and after 1 week of therapy.
6202 18579694 There were no significant differences in expression of TGF-beta, TGF-beta RII, Foxp3, IFN-gamma, and GATA-3 between the groups.
6203 18579694 Differential expression of interleukin-4 (IL-4) and IL-4 delta 2 mRNA, but not transforming growth factor beta (TGF-beta), TGF-beta RII, Foxp3, gamma interferon, T-bet, or GATA-3 mRNA, in patients with fast and slow responses to antituberculosis treatment.
6204 18579694 This study investigated interleukin-4 (IL-4), IL-4 delta 2, transforming growth factor beta (TGF-beta), TGF-beta RII, Foxp3, GATA-3, T-bet, and gamma interferon (IFN-gamma) transcription in peripheral blood samples of adult pulmonary tuberculosis patients prior to and after 1 week of therapy.

6206 18590786 Lymphocyte proliferation assays using splenocytes from immunized mice showed significant proliferative responses and cytokines interleukin-2 (IL-2), IL-4, IL-10 and IFN-gamma presence in the culture supernatants.
6207 18598729 However, mice immunized with pIRES-ESAT-6-FL presented a more stronger T helper 1 (Th1)-biased response, accompanied by higher levels of lymphocytes proliferation, elevated production of Th1 cytokines (IFN-gamma and IL-2) by spleen cells, as well as increased specific antibody in sera, together with lower levels of Th2 cytokines (IL-4 and IL-10).
6208 18603012 This protection was associated with the induction of an IL-12 dependent specific-IFN-gamma response mediated mainly by CD4(+) T cell, albeit a minor contribution of CD8(+) T cells cannot be ruled out.
6209 18603012 A marked reduction of IgG1 antibody titer against parasite antigens besides an impaired IL-4 and IL-10 cytokine production by parasite specific T cells was observed.
6210 18603012 In this strain protection was associated with a LRP specific IFN-gamma production in lymph nodes draining the challenge site.
6211 18606550 It has been found that the PRR bind unit structures of PAMP, and that PAMP-binding involves several other humoral and cell membrane proteins, exemplified by the more or less simultaneous LPS recognition displayed by MD-2, CD-14 and TLR4 on the cell membrane.
6212 18606550 In turn, this may activate Th1 and Th2 immune responses with production of Th1 or Th2 signature molecules such as IFN-gamma and IL-4, respectively [2-4].
6213 18628832 Such BVLPs up-regulated the level of CD40, CD80, CD86, CD83, and enhanced the secretion of IL-6, IL-10 and TNF-alpha in immature dendritic cells (DCs).
6214 18628832 BVLPs showed a stronger ability to stimulate DCs in terms of cytokine induction as evidenced by 2 to 6 fold higher production of IL-6 and TNF-alpha.
6215 18628832 Further study indicated that IFN-gamma+ and IL-4+ populations in CD4+ T cells increased upon co-cultivation with DCs pre-exposed with BVLPs or SARS-CoV VLPs.
6216 18633632 Both therapies were associated with significant suppression of immediate type response, clinical appearance, dermal cell infiltration, reduced IL-4 production, and augmented IFN-gamma mRNA expression compared to placebo-treated mice.
6217 18642727 Vaccine therapy significantly reduces plasma level of IFN-gamma and increases IL-4 level.
6218 18653385 The effect of beta-interferon therapy on myelin basic protein-elicited CD4+ T cell proliferation and cytokine production in multiple sclerosis.
6219 18653385 We analysed the CD4+ T cell proliferation and cytokine responses elicited by myelin basic protein (MBP) and a foreign recall antigen, tetanus toxoid (TT), in mononuclear cell cultures from fourteen MS patients undergoing IFN-beta therapy.
6220 18653385 The MBP-elicited IFN-gamma-, TNF-alpha- and IL-10 production decreased during therapy (p<0.007-0.03), while the IL-6 production increased (p<0.03).
6221 18653385 No significant change was observed in the MBP-induced CD4+ T cell proliferation, or in the production of IL-4, IL-5 and brain-derived neurotrophic factor.
6222 18653385 In comparison, IFN-beta therapy reduced IFN-gamma and IL-4 responses to TT (p<0.003 and p<0.04).
6223 18653385 Thus, IFN-beta inhibits IFN-gamma production in general, presumably alleviating the detrimental influence of IFN-gamma in MS.
6224 18653385 However, the increase in proinflammatory IL-6 and the decrease in anti-inflammatory IL-10 responses suggest that IFN-beta has more diverse effects than previously assumed.

6226 18653385 We analysed the CD4+ T cell proliferation and cytokine responses elicited by myelin basic protein (MBP) and a foreign recall antigen, tetanus toxoid (TT), in mononuclear cell cultures from fourteen MS patients undergoing IFN-beta therapy.
6227 18653385 The MBP-elicited IFN-gamma-, TNF-alpha- and IL-10 production decreased during therapy (p<0.007-0.03), while the IL-6 production increased (p<0.03).
6228 18653385 No significant change was observed in the MBP-induced CD4+ T cell proliferation, or in the production of IL-4, IL-5 and brain-derived neurotrophic factor.
6229 18653385 In comparison, IFN-beta therapy reduced IFN-gamma and IL-4 responses to TT (p<0.003 and p<0.04).
6230 18653385 Thus, IFN-beta inhibits IFN-gamma production in general, presumably alleviating the detrimental influence of IFN-gamma in MS.
6231 18653385 However, the increase in proinflammatory IL-6 and the decrease in anti-inflammatory IL-10 responses suggest that IFN-beta has more diverse effects than previously assumed.

6237 18675465 The double mutant [R(91), A(96)]MBP(83-99) was able to antagonize IFN-gamma production in vitro by T cells against the native MBP(83-99) peptide.
6238 18675592 Whereas intramuscular injection of pGAD65 promoted a predominant type 1 CD4(+) T cell response and failed to suppress ongoing beta cell autoimmunity, gene gun vaccination preferentially induced IL-4 secreting CD4(+) T cells and significantly delayed the onset of diabetes.
6239 18675866 Antigen-specific T-cell proliferation, IL-4, IL-2 and IFN-gamma producing cells, and secretory IgA were mostly detected in animals receiving MALP-2 as adjuvant.
6240 18677602 In the Abeta(42) group, IL2 and IFN-gamma were relatively low and IL4 and IL10 were relatively high.
6241 18677602 By contrast, IL4 and IL10 were much higher in the Abeta(1-15) group and IL2 and IFN-gamma were much higher in the Abeta(36-42) group.
6242 18677602 In the Abeta(42) group, IL2 and IFN-gamma were relatively low and IL4 and IL10 were relatively high.
6243 18677602 By contrast, IL4 and IL10 were much higher in the Abeta(1-15) group and IL2 and IFN-gamma were much higher in the Abeta(36-42) group.

6245 18684965 A Salmonella vector expressing colonization factor Ag I (CFA/I), shown to behave as an anti-inflammatory vaccine, stimulates the production of CD4(+)CD25(+) T cells and regulatory cytokines.
6246 18684965 In this work, we queried whether Salmonella-CFA/I can protect DBA/1 mice from collagen-induced arthritis.
6247 18684965 Clinical findings were accompanied by the suppression of inflammatory cytokines TNF-alpha, IL-1beta, IL-6, and IL-27.
6248 18684965 Vaccination evoked a multi-tier response consisting of IL-4 producing Th2 cells, an increased production of TGF-beta by CD4(+) T cells, and suppression of collagen II-specific CD4(+) T cell proliferation.

6280 18703465 Recently, it has been demonstrated that interaction between dendritic cells (DCs) and thymic stromal lymphopoietin (TSLP), an IL-7-like cytokine, is essential for evoking T(h)2 responses in allergy.
6281 18703465 We demonstrated that BCG redirects TSLP-DCs away from inducing inflammatory T(h)2 cells that produce IL-4, IL-5, IL-13 and tumor necrosis factor (TNF)-alpha and toward regulatory T(h)1 cells that produce IFN-gamma and IL-10.
6282 18703465 We also demonstrated that this functional alteration of TSLP-DCs by BCG depended on both production of IL-12 from DCs and down-regulation of OX40 ligand, a member of the TNF family, on DCs.
6283 18716452 Using these samples, RT-PCR and ELISA analysis were carried out for the comparative study of the cytokines, including TNF-alpha, INF-gamma, IL-2, IL-4, IL-10 and IL-12.
6284 18716452 In the Pohang-infected mice at 120 h, the liver showed a 53 times higher level of TNF-alpha and a 42 times higher level of IFN-gamma than the respective levels at the early time points after infection.
6285 18716452 The levels of TNF-alpha and IFN-gamma induced by LVS were 5 times lower than those induced by the Pohang isolate.
6286 18716452 Also, the organs from the Pohang-infected mice showed higher levels of TNF-alpha, IFN-gamma, IL-10 and IL-12 than the levels in the LVS-infected mice.
6287 18716452 The blood from the Pohang-infected mice at 120 h revealed about a 40 times increased level of IFN-gamma, and IL-10 was also increased by 4 times at 96 h compared to an early infection time point, while IL-4 was not induced during the whole infection period.
6288 18716452 Using these samples, RT-PCR and ELISA analysis were carried out for the comparative study of the cytokines, including TNF-alpha, INF-gamma, IL-2, IL-4, IL-10 and IL-12.
6289 18716452 In the Pohang-infected mice at 120 h, the liver showed a 53 times higher level of TNF-alpha and a 42 times higher level of IFN-gamma than the respective levels at the early time points after infection.
6290 18716452 The levels of TNF-alpha and IFN-gamma induced by LVS were 5 times lower than those induced by the Pohang isolate.
6291 18716452 Also, the organs from the Pohang-infected mice showed higher levels of TNF-alpha, IFN-gamma, IL-10 and IL-12 than the levels in the LVS-infected mice.
6292 18716452 The blood from the Pohang-infected mice at 120 h revealed about a 40 times increased level of IFN-gamma, and IL-10 was also increased by 4 times at 96 h compared to an early infection time point, while IL-4 was not induced during the whole infection period.
6293 18719176 Immunization with either DNA construct induced a significant number of CD8+-type T cells and a strong Th1-type response, with high gamma interferon (IFN-gamma) and low interleukin-4 responses.
6294 18751727 Effect of dose and route of inoculation on the generation of CD4+ Th1/Th2 type of immune response in murine visceral leishmaniasis.
6295 18751727 A potential vaccine candidate for visceral leishmaniasis should favour the development of CD4+ Th1 type of immune response which is further dependent on the dose of antigen and the route of inoculation.
6296 18751727 The present study was carried out to check the effective dose (low, medium and high) and route (subcutaneous, intradermal, intraperitoneal and intracardiac) of inoculation for the development of a CD4+ Th1 type of immune response in BALB/c mice.
6297 18751727 Low-dose inoculation with subcutaneous route elicited maximum IFN-gamma levels, which points towards the generation of Th1 response.
6298 18751727 Maximum IL-4 and IL-10 levels were detected in high-dose inoculation through intracardiac route suggesting the development of Th2 response.
6299 18761388 Through the assay of the amount of interferon (IFN)-gamma and interleukin (IL)-4 in the serum, swine immunized with the fusion protein increased IFN-gamma in the serum which showed that M.T hsp70 potentiated Th1 immune response.
6300 18772925 Lactococcus lactis NZ administered orally stimulated the IgA cycle, increased IgA+ cells in intestine and bronchus, and improved production of BAL IL-4 and IL-10 during infection.
6301 18791167 We reported previously that administration of MIP-1alpha mobilized a population of F4/80(-)B220(-)CD11c+ DC precursors into peripheral blood by the expression of CCR1 and CCR5.
6302 18791167 In this study, we identified a new subset of CCR6+CCR1(-)CCR5(-)B220(-)CD11c(+) cells in MIP-1alpha-administered mice.
6303 18791167 When cultured with GM-CSF, IL-4, and TNF-alpha, these cells differentiated into mature DCs, possessing the typical morphologic characteristics, phenotypes, and antigen-presenting function (termed CCR6+ DC precursors).
6304 18791167 Taken together, this study further demonstrates the mechanism of DC precursor mobilization induced by MIP-1alpha; that is, besides mobilizing DC precursors with CCR1 and CCR5 expressions, MIP-1alpha recruited F4/80+CD11c(-) monocyte/macrophage-producing MIP-3alpha, which finally mobilized the CCR6+ DC precursor subset to amplify the B220(-)CD11c+ DC precursor population.
6305 18793758 The monocytes were then cultured in a closed system using gas permeable Vuelife fluoroethylene propylene (FEP) bags and X-vivo-15 media containing 10 ng/ml granulocyte-macrophage colony-stimulation factor (GM-CSF) and 5 ng/ml Interleukin (IL) 4.
6306 18802458 A critical role of interleukin (IL)-17A was demonstrated: mice lacking interferon-gamma or IL-4 were protected, but not mice lacking IL-17A receptor or mice with neutrophil depletion.
6307 18809450 Immunisation of mice with spores that co-expressed LLO with Protective Antigen (PA) of Bacillus anthracis generated an increase in IgG2a against PA, toxin-neutralising activity coupled with specific IFN-gamma and IL-12 (and reduced IL-4) responses of splenocytes, both indicative of an enhanced Th1 response.
6308 18809757 Clinical responses were significantly associated with a reduction in CD4(+)CD25(+)FOXP3(+) regulatory T cells, an increase in CD3(-)CD56(dim)CD16(+) natural killer (NK) cells, and maturation of lymphocytes to the effector memory stage in either postvaccination peripheral blood or tumor specimen samples.
6309 18809757 In one HLA-A*0201(+) patient who achieved CR, IL-4 release by circulating T cells in response to tumor-specific IgH-encoded peptides was also documented.
6310 18810669 In this study, DCs isolated from peripheral blood monocytes of three pediatric patients with advanced (stage IV) NPC were incubated with whole-tumor-antigen preparations and differentiated into immature DCs in the presence of granulocyte-macrophage colony-stimulating factor and interleukin-4, and then underwent maturation when exposed to tumor necrosis factor-alpha.
6311 18813280 Mice immunized with these dual-delivery carriers demonstrated a significant "switch" toward Th1 response as evidenced by increase in interferon gamma (IFN-gamma) production and decrease in IL-4 production by CD4+ T cells.
6312 18815231 Gamma interferon (IFN-gamma), interleukin 10 (IL-10), IL-12, and low levels of IL-13 and IL-5 but no IL-4 were secreted into the culture supernatant of cord blood mononuclear cells.
6313 18815231 Intracellular staining showed that IL-10 and IL-12 were produced by monocytes and that IFN-gamma was produced by natural killer (NK) cells but not by CD4(+) or CD8(+) T cells.
6314 18815231 In contrast, in the peripheral blood samples collected from babies 13 weeks post-BCG vaccination, IFN-gamma was detected within CD4(+) and CD8(+) cells.
6315 18819411 Influence of immunomodulator of bacterial origin - purified staphylococcal toxoid (PST) - on the synthesisof proinlammatory (IL-1beta, IL-6, TNFalpha, IFN-gamma) and anti-inflammatory (IL- 10) cytokines, as well as cytokines directing the immune response to Th1 (IL-12) or Th2 (IL-4) type was studied in mice.
6316 18819411 Synthesis of several serum interleukins (IL-2, IL-10) did not changed 4 and 24 hours after inoculation irrespective from dose of PST.
6317 18819411 For example, increase of number of cells secreting antibodies to sheep erythrocytes was registered both during increased synthesis of cytokines (4 hours, IL-1beta, IL-6, IL-12) and during period of its depression (IL-6, TNF-alpha, IFN-gamma), as well as during stable production of cytokines (IL-1beta, IL-6, IFN-gamma).
6318 18827187 The levels of proinflammatory cytokines (gamma interferon, tumor necrosis factor alpha, interleukin-1beta [IL-1beta], IL-2) and anti-inflammatory cytokines (IL-4, IL-10), in addition to those of IL-6, were assessed on days 1, 3, and 5 postinfection by enzyme-linked immunosorbent assay, and the ratios of proinflammatory cytokines to anti-inflammatory cytokines were calculated.
6319 18827195 Throughout the infection (until 120 days), we monitored outcome (CFU), molecules involved in the development of immunoregulation (Foxp3, hemoxygenase 1, idoleamine 2,3-dioxygenase, and transforming growth factor beta [TGF-beta]), and indicators of cytokine balance (tumor necrosis factor, inducible nitric oxide synthase, interleukin-4 [IL-4], and IL-4delta2; an inhibitory splice variant of IL-4 associated with improved outcome in human TB).
6320 18827195 Oral M. vaccae had a significant effect on CFU and led to increased expression of Th1 markers and of IL-4delta2, while suppressing IL-4, Foxp3, and TGF-beta.
6321 18827195 Throughout the infection (until 120 days), we monitored outcome (CFU), molecules involved in the development of immunoregulation (Foxp3, hemoxygenase 1, idoleamine 2,3-dioxygenase, and transforming growth factor beta [TGF-beta]), and indicators of cytokine balance (tumor necrosis factor, inducible nitric oxide synthase, interleukin-4 [IL-4], and IL-4delta2; an inhibitory splice variant of IL-4 associated with improved outcome in human TB).
6322 18827195 Oral M. vaccae had a significant effect on CFU and led to increased expression of Th1 markers and of IL-4delta2, while suppressing IL-4, Foxp3, and TGF-beta.
6323 18829103 For example, DCs cultured on collagen and vitronectin substrates generate higher levels of IL-12p40, whereas DCs cultured on albumin and serum-coated tissue culture-treated substrates produce the higher levels of IL-10 compared to other substrates.
6324 18829103 Specifically, we show that substrate-dependent modulation of DC IL-12p40 cytokine production correlates with CD4(+) T-cell proliferation and T(h)1 type response in terms of IFN-gamma producing T-helper cells.
6325 18829103 Furthermore, our results suggest substrate-dependent trends in DC-mediated stimulation of IL-4 producing T-cells, but this T(h)2 type response is not dependent on DC production of IL-10 cytokine.
6326 18838173 Recent data indicate CD4+ lymphocytes are required for effective protection against disease; in particular, cross talk between CD4+ and CD8+ lymphocytes must be functional.
6327 18838173 Interferon (IFN) gamma and interleukin (IL)-4 expressing CD4+ lymphocytes significantly increased 14 days following initial vaccination compared to unvaccinated horses (P<0.05).
6328 18838173 IFN-gamma expressing CD8+ lymphocytes also increased and remained elevated for 110 days.
6329 18838173 Our data indicate that WNV vaccination with an inactivated product effectively induced an antigen-specific antibody responses, as well as CD4+ and CD8+ lymphocyte activation.
6330 18923431 Combining information from previous studies on AEs related to smallpox vaccination with the genetic and proteomic attributes identified by RF, we built a comprehensive model of AE development that includes the cytokines intercellular adhesion molecule-1 (ICAM-1 or CD54), interleukin-10 (IL-10), and colony stimulating factor-3 (CSF-3 or G-CSF) and a genetic polymorphism in the cytokine gene interleukin-4 (IL4).
6331 18923553 The presence of both IgG1 and IgG2a anti-PppA antibodies in serum and BAL and the production of both interferon gamma and interleukin-4 by spleen cells from immunized mice indicated that L. lactis PppA+ stimulated a mixture of Th1 and Th2 responses.
6332 18941225 Furthermore, LC16mOrVV-N-immunized mice upon infection exhibited significant up-regulation of both Th1 (IFN-gamma, IL-2) and Th2 (IL-4, IL-5) cytokines and down-regulation of anti-inflammatory cytokines (IL-10, TGF-beta), resulting in robust infiltration of neutrophils, eosinophils, and lymphocytes into the lung, as well as thickening of the alveolar epithelium.

6339 18981522 Hamsters were immunized with killed L. interrogans serovar Autumnalis before challenge to study cytokine mRNA expression levels (interferon [IFN]-gamma, tumor necrosis factor [TNF]-alpha, interleukin [IL]-10, and IL-4).
6340 18981522 IFN-gamma and TNF-alpha mRNA expression levels correlated with the severity of infection and lung pathology, whereas IL-4 and IL-10 expression levels were significantly higher in vaccinated groups.

6342 18988742 Interferon-gamma and interleukin-4 reciprocally regulate CD8 expression in CD8+ T cells.
6343 18988742 Here we show that IFN-gamma and IL-4 exert opposing effects on the expression of CD8alpha mRNA and surface CD8 protein during CD8(+) T cell activation.
6344 18988742 IL-4 caused down-regulation of surface CD8 on ovalbumin (OVA)(257-264)-specific TCR-transgenic OT-I CD8(+) T cells activated with OVA(257-264)-coated antigen presenting cells or polyclonal stimuli, and on wild type CD8(+) T cells activated with polyclonal stimuli.
6345 18988742 When WT or IFN-gamma-deficient OT-I CD8(+) T cells were analyzed 9 days after co-injection with control or IL-4-expressing OVA(+) tumor cells into RAG-2(-/-)gamma c(-/-) mice, CD8 levels were highest on WT donor cells from mice that received the control tumor and lowest on IFN-gamma-deficient donor cells from mice that received the IL-4-expressing tumor.

6361 18988742 The data reveal an unexpected role for IFN-gamma in tuning the CD8 co-receptor during primary CD8(+) T cell activation both in vitro and in vivo.
6362 18996429 Immunization with antigen (sAg) encapsulated in saccharosome resulted in enhancement of CD4+ and CD8+ T cell populations and also up-regulated the expression of CD80 and CD86 molecules on the surface of antigen presenting cells.
6363 18996429 Further, immunization with saccharosome-encapsulated sAg-induced elevated levels of both IFN-gamma and IL-4 cytokines in the immunized mice when compared to egg PC liposome encapsulated sAg or its IFA emulsified form.
6364 19006834 It was revealed that fractions of neutrophilokines regulate IL-2 synthesis by Th1-helpers, IL-4 and IL-5 synthesis by Th2-helpers and also expression of IL-2 receptors by immunocompetent cells.
6365 19006832 Serum concentrations of cytokines (IFN-gamma, TNF-alpha, IL-2, IL-4, IL-6, IL-8) and antibody levels to influenza virus antigens were studied in adults vaccinated with split-vaccine against influenza.
6366 19006832 Study of cytokine profile showed absence of significant changes of IFN-gamma, TNF-alpha, IL-2, IL-4 levels and considerable variability of IL-6 and IL-8 baseline levels as well as their dynamics after vaccination.
6367 19006832 Direct correlation between IL-6 and IL-8 levels was observed during whole period post-immunization.
6368 19006832 Serum concentrations of cytokines (IFN-gamma, TNF-alpha, IL-2, IL-4, IL-6, IL-8) and antibody levels to influenza virus antigens were studied in adults vaccinated with split-vaccine against influenza.
6369 19006832 Study of cytokine profile showed absence of significant changes of IFN-gamma, TNF-alpha, IL-2, IL-4 levels and considerable variability of IL-6 and IL-8 baseline levels as well as their dynamics after vaccination.
6370 19006832 Direct correlation between IL-6 and IL-8 levels was observed during whole period post-immunization.
6371 19008134 Furthermore, the highest levels of interleukin (IL)-2, interferon-gamma and IL-4 were induced following priming with the DNA vaccine and boosting with the recombinant protein.
6372 19020105 The lymphoproliferative and cytokine responses (interleukin-2 [IL-2], IL-4, IL-5, IL-10, gamma interferon, and tumor necrosis factor alpha) were assessed for 11 HIV-seropositive, Cryptosporidium-positive (group I) patients; 20 HIV-seropositive, Cryptosporidium-negative (group II) patients; 10 HIV-seronegative, Cryptosporidium-positive (group III) patients, including four post-renal transplant (group IIIa) and 6 presumably immunocompetent (group IIIb) patients; and 20 HIV-seronegative, Cryptosporidium-negative healthy individuals (group IV).
6373 19022317 Our results indicate that both liposomes and microspheres prove to be better adjuvants compared to conventional alum as revealed by enhanced antibody titers, lymphocyte proliferation and significant enhancement in both Th1(IL-12, IFN-gamma) and Th2 (IL-4, IL-10) cytokines.
6374 19023533 The mice given CIA07 plus alum also showed a marked increase in the number of IFN-gamma-, IL-2-, and IL-4-producing CD4(+) T cells among their splenocytes.
6375 19042022 However, upon immunization, the H164V APL considerably downregulated proliferation and cytokine responses to the wild type LACK 161-175 peptide, while immunization with the weak agonist, MHC contact APL S171K, increased the IFN-gamma/IL-4 ratio to the wild type peptide.
6376 19054565 Proliferation in 5-day assays was carried out via tritiated-thymidine incorporation, while IL4 and IFNgamma production was assessed via sandwich enzyme-linked immunosorbent tests (ELISA) of TCL culture supernatants.
6377 19054578 In this study, we evaluated the patterns of TLR2-, TLR3- and TLR9-expressing antigen presenting cells (APCs) in spleen and blood of gnotobiotic (Gn) pigs after colonization with a mixture of two strains of lactic acid bacteria (LAB), Lactobacillus acidophilus and Lactobacillus reuteri or infection with the virulent human rotavirus (HRV) Wa strain.
6378 19054578 We demonstrated that LAB induced strong TLR2-expressing APC responses in blood and spleen, HRV induced a TLR3 response in spleen, and TLR9 responses were induced by either HRV (in spleen) or LAB (in blood).
6379 19054578 LAB and HRV have an additive effect on TLR2- and TLR9-expressing APC responses, consistent with the adjuvant effect of LAB.
6380 19054578 LAB enhanced the IFN-gamma and IL-4 responses in serum, but it had a suppressive effect on the TLR3- and TLR9-expressing CD14- APC responses in spleen and the serum IFN-alpha response induced by HRV.
6381 19054578 These results elucidated the systemic TLR2-, TLR3-, and TLR9-expressing monocyte/macrophage and cDC responses after HRV infection, LAB colonization, and the two combined.
6382 19054933 RT-PCR revealed that all allergen-treated mice had marked increase of IL-13, IL-4 and TNF-alpha gene expressions, slight increase of IL-5 gene expression, and absence of detectable IFN-gamma gene expression in comparison to the non-allergenic controls.
6383 19070639 Moreover, the fusion of HSP70 markedly induced both IFN-gamma and IL-4 in pigs' sera.
6384 19070678 Our results demonstrate that immunization with LigB produced strong humoral immune responses as revealed by high titers against each fragment and significant enhancement in Th2 cytokines (IL-4, IL-10).
6385 19091870 Higher CS also correlated with higher levels of mRNAs for PD-1, CD4, CD8, F4/80, interleukin-4, gamma interferon, granzyme A, and granzyme B in both cornea and TG.
6386 19091870 These results suggest that (i) the immunopathology induced by HSV-1 infection does not correlate with primary virus replication in the eye; (ii) increased CS appears to correlate with increased latency in the TG, although the possible cause-and-effect relationship is not known; and (iii) increased latency in mouse TG correlates with higher levels of PD-1 mRNA, suggesting exhaustion of CD8+ T cells.
6387 19095381 Statistical analysis of qRT-PCR data revealed that four genes, complement component C3, IFN-gamma, IL-4 and RANTES were downregulated in infected animals (P<0.05).
6388 19095381 The mRNA levels of IFN-gamma and C3 showed a peak (>15-fold increase) at 5 wpi, whereas transcripts for RANTES and IL-4 showed a peak (>2-fold increase) at 13 wpi in BCG-immunized animals when compared to non-immunized controls.
6389 19095381 Statistical analysis of qRT-PCR data revealed that four genes, complement component C3, IFN-gamma, IL-4 and RANTES were downregulated in infected animals (P<0.05).
6390 19095381 The mRNA levels of IFN-gamma and C3 showed a peak (>15-fold increase) at 5 wpi, whereas transcripts for RANTES and IL-4 showed a peak (>2-fold increase) at 13 wpi in BCG-immunized animals when compared to non-immunized controls.
6391 19103226 PBMCs from the BT-PrV-gB-N-term groups, isolated after the peptide boost injection, produced IFN-gamma and IL-4 mRNAs in vitro when stimulated with FMDV peptides.
6392 19110023 Our data identified distinct immunological profiles elicited by Leishvaccine and Leishmune, with the Leishvaccine triggering a mixed, IFN-gamma and IL-4, cytokine pattern in addition to high levels of anti-Leishmania IgG1, whereas the Leishmune induced an immunological pattern characterized by enhanced levels of IFN-gamma, NO and anti-Leishmania chagasi IgG2.
6393 19110625 With the perspective of bioengineering DCs from the inside-out, we also describe a one-hit LV transduction method for constitutive expression of GM-CSF and IL-4 genes, which allows self-differentiation of mouse and human hematopoietic precursor cells into highly viable and potent DCs.
6394 19111573 A construct coding for the complete Phl p 5 induced T-cell activation, IFN-gamma and IL-4 production.
6395 19116444 and IL-4 production than other constructs, except IL-2 production.
6396 19124761 Harvested early, these cells produced IFN-gamma, TNF, and RANTES after ex vivo stimulation.
6397 19124761 By contrast, those recruited 5 days after challenge made IL-4, IL-5, and IL-10.
6398 19129466 Among the patients with active TB, we found (i) normal to slightly elevated peripheral CD4(+) and CD8(+) T-cell counts but a significant reduction in the number of NK cells; (ii) CD4(+) T cells were the major cell type producing IFN-gamma, a type 1 cytokine; (iii) small percentages of CD8(+) T cells were also primed for IFN-gamma production; (iv) the production of interleukin-4 (IL-4), a type 2 cytokine, was not prominent; and (v) the sensitivity and the specificity of the QFT-G assay were 88.2% and 18%, respectively, and those of the ICC assay were 94.1% and 36.4%, respectively.
6399 19139565 By contrast, TLR9 was not highly expressed by naturally occurring CD4+CD25+ Treg or by Th1 and Th2 effector cells.
6400 19139565 Furthermore, ingestion of calcitriol (1alpha25VitD3) by human volunteers led to an increase of both IL-10 and TLR9 expression by CD3+CD4+ T cells analyzed directly ex vivo.
6401 19139565 Stimulation of 1alpha25VitD3-induced IL-10-secreting Treg with TLR9 agonists, CpG oligonucleotides, resulted in decreased IL-10 and IFN-gamma synthesis and a concurrent loss of regulatory function, but, unexpectedly, increased IL-4 synthesis.
6402 19145371 The serum concentration of IFN-gamma decreased about 2-fold 1.5-2.0 years after the start of vaccine therapy, whereas the concentration of IL-4 increased 2-3 fold.
6403 19150742 In vitro stimulation of splenocytes from vaccinated mice with either recombinant IF3 (rIF3) or crude Brucella protein extracts resulted in a T-cell proliferative response and induction of interferon gamma secretion, but not interleukin-4.
6404 19168736 Again, mice vaccinated through the i.p. and i.v. routes showed high levels of NO production after challenge infection. s.c. vaccination resulted in an increased capacity of the spleen cells to produce prechallenge transforming growth factor beta (TGF-beta) levels during the in vitro antigen recall response, whereas i.p. immunization induced production of prechallenge gamma interferon, interleukin-12 (IL-12), and IL-4 levels, with a Th1 bias.
6405 19181353 However, IL-4, IL-10, TNF-alpha and IFN-gamma were expressed in significantly higher levels by survivors (for all the four cytokines in lymph nodes; for IL-4, IL-10 and TNF-alpha in spleen; for IL-4, TNF-alpha and IFN-gamma in lung, and only for TNF-alpha in brain), thus suggesting a role of these four cytokines in the adaptive response, which might contribute to protection against H. parasuis infection.
6406 19188665 Experimental tumor vaccination and adoptive T-cell therapies show that interferon-gamma (IFN-gamma)-producing CD4(+) T helper cells (Th1) can be highly effective in tumor prevention and therapy.
6407 19188665 Th-cell priming against EpCAM inevitably resulted in interleukin-4 (IL-4)-dominated Th2 responses, even under most stringent Th1-inducing conditions.
6408 19188665 To analyze the role of IL-4 in tumor immune evasion, we generated EpCAM-reactive Th1 cells from IL-4.ko mice.
6409 19188665 Inhibition of tumor growth by Th1 cells resulted in intra-tumoral expression of cytokines of the IL-12 family and of IFN-gamma.
6410 19188665 Experimental tumor vaccination and adoptive T-cell therapies show that interferon-gamma (IFN-gamma)-producing CD4(+) T helper cells (Th1) can be highly effective in tumor prevention and therapy.
6411 19188665 Th-cell priming against EpCAM inevitably resulted in interleukin-4 (IL-4)-dominated Th2 responses, even under most stringent Th1-inducing conditions.
6412 19188665 To analyze the role of IL-4 in tumor immune evasion, we generated EpCAM-reactive Th1 cells from IL-4.ko mice.
6413 19188665 Inhibition of tumor growth by Th1 cells resulted in intra-tumoral expression of cytokines of the IL-12 family and of IFN-gamma.
6414 19191902 Analysis of interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) levels in bronchoalveolar lavage fluid (BALF) and lung tissue revealed that the suppression was associated with a shift from a Th2 response to a Th1 response.
6415 19191902 At the same time, rBCG induced a CD4(+) CD25(+) Foxp3(+) T-cell subtype that could suppress the proliferation of Th2 effector cells in vitro in an antigen-specific manner.
6416 19191902 Moreover, suppression of CD4(+) CD25(+) T cells could be adoptively transferred.
6417 19191902 The generic immune response is associated with a shift from a Th2 to a Th1 cytokine response, whereas the specific immune response against Der p2 appears to be related to the expansion of transforming growth factor-beta (TGF-beta)-producing CD4(+) CD25(+) Foxp3(+) regulatory T cells. rBCG can suppress asthmatic airway inflammation through both immune deviation and immune suppression and may be a feasible, efficient immunotherapy for asthma.
6418 19195490 In vitro cell proliferation studies in the presence of GPI-attached PA63 peptides revealed that there was a clonal expansion of CD4(+) NK1.1(+) helper T cell population which rapidly produced IL-4 in response to T cell receptor ligation.
6419 19195490 In addition, the group pTPA.GPI-PA63 also displayed low magnitude MHC-II restricted (CD1d-independent) NKT cell and CD4(+) T cell helper responses in response to non-GPI attached PA63 peptides which overall resulted in the heightened responses seen for this group.
6420 19204092 Anti-PCM vaccine formulations based on the secreted fungal cell wall protein (gp43) or the derived P10 sequence containing a CD4(+) T-cell-specific epitope have shown promising results.
6421 19204092 BALB/c mice immunized with gp43 developed high-specific-serum immunoglobulin G1 responses and enhanced interleukin-4 (IL-4) and IL-10 levels.
6422 19221745 CD4(-)CD8(-) T cell clones display unconventional cytotoxicity and specifically kill tumor cells expressing mutated TGFbeta receptor II.
6423 19221745 Cytokine profiling on the long-term survivors demonstrates high IFN gamma/IL10-ratios, favoring immunity over tolerance, and secretion of multiple chemokines likely to mobilize the innate and adaptive immune system.
6424 19221745 Most IFN gamma(high)/IL4(low)/IL10(low) cultures include high concentrations of hallmark Th2-cytokines IL-5 and IL-13.
6425 19248157 Results showed that specific T lymphocyte proliferation and the expression of the Th1-type cytokines (IL-2 and IFN-gamma) were higher in the gp120N-IFN-gamma group than the other two groups (P < 0.05).
6426 19248157 No difference was observed in the expression levels of the Th2-type cytokines (IL-4 and IL-10; P > 0.05).
6427 19252490 Using an interleukin 4-reporter system, we show here that CD4(+) follicular helper T cells constituted essentially all of the cytokine-secreting T cells in lymph nodes and were functionally distinct from T cells secreting the same cytokine in peripheral tissues.
6428 19261771 CD3(+), CD4(+), CD8(+), and T-cell receptor gammadelta-positive (gammadelta(+)) cells were identified in the gate of blast lymphocytes.
6429 19261771 Gamma interferon, tumor necrosis factor alpha, interleukin-4 (IL-4), and IL-10 levels in supernatants and serum anti-PT IgG levels were determined using enzyme-linked immunosorbent assay (ELISA).
6430 19261771 The frequencies of proliferating CD4(+), CD8(+), and gammadelta(+) cells, cytokine concentrations in supernatants, and the geometric mean titers of anti-PT IgG were similar for the two vaccination groups.
6431 19291915 Blast cells of two relapsed AML patients were harvested for DC generation in serum-free culture medium containing clinical-grade cytokines GM-CSF, IL-4 and TNF-alpha.
6432 19291915 These DC vaccines exhibited mature DC surface phenotypic markers of CD83, CD86 and HLA-DR, and negative for haemopoietic markers.
6433 19292768 The Th2 cytokines IL-4 and IL-13 drive this response, whereas IL-10, IL13Ralpha2, IFN-gamma and a subset of regulatory T-cells act to limit schistosome induced pathology.
6434 19303121 Using real-time PCR quantification assay, expression of Th1 (IL-2, IL-12p40, IFNgamma); Th2 (IL-4, IL-10) and inflammatory (IL-6, TNFalpha) cytokines were quantified weekly for the entire three-week duration of the experiment.
6435 19303121 It was noted that IFNgamma, IL-10 and TNFalpha had peaked on week three post-vaccination while the remaining cytokines peaked on the second week and decreased by the third week.
6436 19303121 The counteraction between IFNgamma and IL-4 was noted as well as the possible suppressive action of IL-10 to that of IL-2 and IL-12, which is a common phenomenon between Th1 and Th2 cytokines.
6437 19303121 Synergy between TNFa and IL-6 was also observed.
6438 19303121 Using real-time PCR quantification assay, expression of Th1 (IL-2, IL-12p40, IFNgamma); Th2 (IL-4, IL-10) and inflammatory (IL-6, TNFalpha) cytokines were quantified weekly for the entire three-week duration of the experiment.
6439 19303121 It was noted that IFNgamma, IL-10 and TNFalpha had peaked on week three post-vaccination while the remaining cytokines peaked on the second week and decreased by the third week.
6440 19303121 The counteraction between IFNgamma and IL-4 was noted as well as the possible suppressive action of IL-10 to that of IL-2 and IL-12, which is a common phenomenon between Th1 and Th2 cytokines.
6441 19303121 Synergy between TNFa and IL-6 was also observed.
6442 19307173 The mRNA expression of interleukin-2 (IL-2), interferon-γ (IFN-γ), interleukin-4 (IL-4) and interleukin-12 (IL-12) was determined using a semi-quantitative RT-PCR assay.
6443 19307173 GGS altered the expression of IL-4 and IL-12 in T lymphocytes.
6444 19307173 The mRNA expression of interleukin-2 (IL-2), interferon-γ (IFN-γ), interleukin-4 (IL-4) and interleukin-12 (IL-12) was determined using a semi-quantitative RT-PCR assay.
6445 19307173 GGS altered the expression of IL-4 and IL-12 in T lymphocytes.
6446 19338001 Our results have revealed an unexpected dichotomy in the effector phase following cancer vaccination where anti-tumor immunity is mediated via a STAT6 and IL-4-dependent pathway, whereas autoimmune pathology is mediated via STAT4 through a mechanism that relies partially on IFN-gamma.
6447 19342965 Immature dendritic cells (iDCs) are often produced by the stimulation of peripheral blood monocytes with interleukin (IL)-4 and granulocyte macrophage-colony stimulating factor.
6448 19342965 The purpose of this study was to determine if the DC maturation cocktail LPS plus IFN-gamma could be improved by the addition of 2 other DC maturation agents IL-1beta and tumor necrosis factor (TNF)-alpha.
6449 19342965 Monocytes were isolated from the peripheral blood mononuclear cell concentrates by elutriation and were incubated for 3 days with granulocyte macrophage-colony stimulating factor and IL-4 to produce iDCs. iDCs from each subject were divided into 3 and were incubated for 24 hours with LPS plus IFN-gamma; LPS, IFN-gamma, plus IL-1beta; or LPS, IFN-gamma, IL-1beta, plus TNF-alpha to produce mDCs.
6450 19342965 The DCs were compared by measuring the expression of costimulator and antigen presenting molecules (CD80, CD83, CD86, and human leukocyte antigen-DR) by flow cytometry, cytokine production (IL-12p70 and IL-10) by enzyme-linked immunosorbent assay and global gene expression using an oligonucleotide microarray.
6451 19342965 There was no benefit of adding IL-1beta and TNF-alpha to LPS and IFN-gamma to produce mDCs.
6452 19342965 Immature dendritic cells (iDCs) are often produced by the stimulation of peripheral blood monocytes with interleukin (IL)-4 and granulocyte macrophage-colony stimulating factor.
6453 19342965 The purpose of this study was to determine if the DC maturation cocktail LPS plus IFN-gamma could be improved by the addition of 2 other DC maturation agents IL-1beta and tumor necrosis factor (TNF)-alpha.
6454 19342965 Monocytes were isolated from the peripheral blood mononuclear cell concentrates by elutriation and were incubated for 3 days with granulocyte macrophage-colony stimulating factor and IL-4 to produce iDCs. iDCs from each subject were divided into 3 and were incubated for 24 hours with LPS plus IFN-gamma; LPS, IFN-gamma, plus IL-1beta; or LPS, IFN-gamma, IL-1beta, plus TNF-alpha to produce mDCs.
6455 19342965 The DCs were compared by measuring the expression of costimulator and antigen presenting molecules (CD80, CD83, CD86, and human leukocyte antigen-DR) by flow cytometry, cytokine production (IL-12p70 and IL-10) by enzyme-linked immunosorbent assay and global gene expression using an oligonucleotide microarray.
6456 19342965 There was no benefit of adding IL-1beta and TNF-alpha to LPS and IFN-gamma to produce mDCs.
6457 19350415 The cytokines IL-4, IL-10, and IFN-gamma were produced in mice of Group 1.
6458 19352703 The results revealed that cytokine production by CD4(+) T cells was induced as early as 5 days after infection and the maintenance of higher levels of IL-4 and IL-10 may be associated with the protection of BALB/c mice from early death.
6459 19393709 Moreover, the use of MPLA and Al(OH)(3) combination led to the induction of the highest IgG levels together with the secretion of both IFN-gamma and IL-4.
6460 19406102 TNF superfamily member, TL1A, is a potential mucosal vaccine adjuvant.
6461 19406102 Among the TNFS cytokines, intranasal immunization with OVA plus APRIL, TL1A, and TNF-alpha exhibited stronger immune response than those immunized with OVA alone.
6462 19406102 The OVA-specific immune response of TL1A was characterized by high levels of serum IgG1 and increased production of IL-4 and IL-5 from splenocytes of immunized mice, suggesting that TL1A might induce Th2-type responses.
6463 19410625 The histopathological staging and collagen assessment for fibrosis showed that the cocktail PDDV presented an obvious down-regulation effect on hepatic fibrosis caused by chronic S. japonicum infection (P<0.05), and IFN-gamma, IL-4 and IL-13 mRNAs in liver detected by RT-PCR also showed that the cocktail PDDV represented the ability to up-regulate Th1-type responses, which paralleled with a decrease expression of alpha-SMA (P<0.05) and the up-regulated MMP9/TIMP1 balance (P<0.05) when compared to the control groups.
6464 19410625 Therefore, it is indicated that the cocktail PDDV can significantly attenuate hepatic fibrosis, in parallel with the decreased HSCs activation and the up-regulated MMP9/TIMP1 balance in favor of matrix degradation, which may be partially dependent on the increased Th1 response to restore the Th1/Th2 balance.
6465 19414765 PI cytokines also induced significant production of effector cytokines, including IL-4, IFN-gamma, IL-17, and IL-21, by both young and aged CD4 T cells.
6466 19428861 Cells from mice inoculated with killed parasites produced significantly more antigen-specific IL-4 and less IFN-gamma than those from mice injected with live parasites.
6467 19428861 Inclusion of CpG ODN into killed parasite preparations changed the early response to killed parasites from IL-4 to a predominantly IFN-gamma response, resulting in better protection following secondary high dose virulent L. major challenge.
6468 19428861 Cells from mice inoculated with killed parasites produced significantly more antigen-specific IL-4 and less IFN-gamma than those from mice injected with live parasites.
6469 19428861 Inclusion of CpG ODN into killed parasite preparations changed the early response to killed parasites from IL-4 to a predominantly IFN-gamma response, resulting in better protection following secondary high dose virulent L. major challenge.
6470 19428897 Our results show that rPvRAP2 is immunogenic in both formulations, finding a trend of higher cytokine levels in immunized monkeys, specially in IL-4 levels (using Freund's adjuvant) and IL-5 (using Alum hydroxide).
6471 19447110 Of the dams, the groups receiving either recNcROP2 alone or the combination of all three antigens did not exhibit any morbidity, the groups receiving ROP2 mixed with either MIC1 or MIC3 exhibited reduced numbers of deaths, and in the infection control group and the adjuvant group 50% and 43% of mice, respectively, succumbed to disease.
6472 19447110 Serological analysis of humoral (total IgG, IgG1 and IgG2a) and serum cytokine (IL-4 and IFN-gamma) responses showed that this effect was associated with a Th-2-biased immune response, with a clearly elevated IL-4/IFN-gamma ratio in the mice receiving all three antigens in combination.
6473 19484809 Further, there was an appreciable increase in interleukin-2 (IL-2) and IL-4 production in lymphocytes isolated from immunized mice as compared with control.
6474 19501551 Moreover, high levels of IL-4, IL-10 and anti-CD25 antibody were produced by splenocytes of vaccinated mice after CD25 protein restimulation in vitro.
6475 19503834 Analysis of the cytokine responses in immunized mice revealed that all the vaccinated groups produced prechallenge interferon-gamma, interleukin-12 and interleukin-4.
6476 19523911 During vaccination of rN protein, the expression of IFN-gamma and IL-10 was evidently up-regulated in splenocytes at different time points, while the expression of IL-2 and IL-4 was not.
6477 19542458 The efficacy was supported by a surge in inducible NO synthase, IFN-gamma, TNF-alpha, and IL-12 mRNA levels along with extreme down-regulation of TGF-beta, IL-4, and IL-10.
6478 19542471 Specifically, we detect elevated levels of IL-4, IL-5, IL-13, and eosinophils in bronchoalveolar lavage fluid of PVM-infected mice that were vaccinated with PVM Ags, but not among mice vaccinated with formalin-inactivated Ags from uninfected cells (control Ags).
6479 19542471 We found that eosinophil deficiency had no impact on virus titer in PVM Ag-vaccinated mice, nor on weight loss or levels of CCL11 (eotaxin-1), IFN-gamma, IL-5, or IL-13 in bronchoalveolar lavage fluid.
6480 19542471 However, levels of both IL-4 and CCL3 (macrophage inflammatory protein-1alpha) in bronchoalveolar lavage fluid were markedly diminished in PVM Ag-vaccinated, PVM-infected eosinophil-deficient mice when compared with wild-type controls.

6484 19578511 Human monocytes were cultured with GM-CSF and IL-4 for 6 days under standard conditions, followed by another 2 days in the presence of M1, M4, T-cadinol or calamenene.
6485 19578511 The expression levels of CD1a, CD80, CD83, CD86 and HLA-DR on M1-primed DC, M4-primed DC, T-cadinol-primed DC and calamenene-primed DC were enhanced with a concomitant decrease in endocytic activity.
6486 19578511 Naïve T cells co-cultured with allogeneic M1-primed DC, M4-primed DC, T-cadinol-primed DC or calamenene-primed DC turned into typical Th1 cells, which produced large quantities of IFN-gamma and released small amounts of IL-4 depending on IL-12 secretion.
6487 19578511 In the CTL assay (cytotoxic T-lymphocyte assay), the production of IFN-gamma and (51)Cr release on M4-primed DC was more augmented than of immature DC or TNF-alpha-primed DC.

6508 19615870 Evaluation of lesion development and splenic parasite burden after challenge with L. major, evaluation of Th1 cytokine (IFN-gamma) and Th2 cytokine (IL-4), and titration of IgG isotypes were carried out to assess the type of generated immune response and extent of protection.
6509 19622401 Production of Th2 cytokines (IL-4, IL-5 and IL-13) by splenocytes of the rAd-F0DeltaTM and rAd-F0 immunized mice was markedly lower than those released by animals administered with heat-inactivated RSV-B1 (HIRSV-B1).
6510 19628058 WSL enhanced Th1 cytokine IFN-gamma expression in Con A primed splenocytes in vitro.
6511 19628058 When given orally for 2 weeks to BALB/c mice immunized with emulsion of OVA in Freund's adjuvant (OVA-FCA), it caused dose-dependent proliferation of T cells and improved their ability to secrete IL-2 and IFN-gamma, but moderately down-regulated Th2 cytokine IL-4.
6512 19628058 Flow cytometric analysis of lymphocyte surface markers of T cells CD3(+), CD4(+) and CD8(+), and B cells CD19(+) indicated prominent enhancement in proliferation and differentiation of lymphocytes.
6513 19628058 Further, the effect of WSL in immunized mice elicited up-regulation of beta-integrins LFA (CD11a) and Mac-1 (CD11b) in splenocytes.
6514 19628058 Co-stimulatory molecules CD80 and CD86 that are important secondary signals for the activation of immune system elicited remarkable enhanced expression when observed in spleen-derived macrophages isolated from WSL treated mice.
6515 19637624 Compared with the control, the levels of IL-2, IFN-gamma, IL-4, and IL-10 expression by splenic lymphocytes from mice immunized with pA and pEA were significantly increased.
6516 19637624 In addition, we found that the levels of IL-2, IFN-gamma and IL-4 from the mice immunized with pEA was higher than mice immunized with pA did.
6517 19637624 Compared with the control, the levels of IL-2, IFN-gamma, IL-4, and IL-10 expression by splenic lymphocytes from mice immunized with pA and pEA were significantly increased.
6518 19637624 In addition, we found that the levels of IL-2, IFN-gamma and IL-4 from the mice immunized with pEA was higher than mice immunized with pA did.
6519 19638322 The immunization preferentially stimulates the production of IFN-gamma and IL-2 in splenocytes which suggests a Th1 type response with a concomitant down-regulation of IL-10 and IL-4.
6520 19649391 All experimental groups (N = 10 mice per group) showed statistically significant increases in antigen-specific antibodies, in cytokines IL-4 and IL-10, as well as in the microscopic agglutination test and splenocyte proliferation compared with the pVAX1 control group.
6521 19651872 Circumsporozoite protein (CSP)-specific responses were detected in approximately half of RTS,S-immunized infants and included gamma interferon (IFN-gamma), interleukin-2 (IL-2), and combined IL-2/IL-4 responses.
6522 19651872 The median stimulation indices of cytokine-producing CD4(+) and CD8(+) cells were very low but significantly higher in RTS,S-immunized infants than in infants that received the comparator vaccine.
6523 19651872 Protection against subsequent malarial infection tended to be associated with a higher percentage of individuals with CSP-specific IL-2 in the supernatant (P = 0.053) and with higher CSP-specific IFN-gamma-producing CD8(+) T-cell responses (P = 0.07).
6524 19654068 However, a mixed Th1/Th2 cell response was evidenced in BLG-reactivated splenocytes from mice intranasally pretreated, with enhanced secretions of Th1 cytokines (IFN-gamma and IL-12) and Th2 cytokines (IL-4 and IL-5) whereas only production of Th1 cytokines, but not Th2 cytokines, was enhanced in BLG-reactivated splenocytes from mice orally pretreated.
6525 19656994 Bone-marrow derived DCs (BMDCs) were cultured in the presence of granulocyte-macrophage colony-stimulating factor and interleukin-4.
6526 19658096 All individuals demonstrated stable IFN-gamma, IL-2 and IL-4 ex vivo ELISPOT effector responses against P. falciparum-infected RBC (iRBC) Ag, 28 and 90 days after challenge.
6527 19658096 However, infected RBC-specific central memory responses, as measured by IFN-gamma cultured ELISPOT, were low and unstable over time, despite CD4(+) T cells being highly proliferative by CFSE dilution, and showed an inverse relationship to parasite density.
6528 19658096 This activity could not be accounted for by the expression of IL-10, TGF-beta, FOXP3 or CTLA-4, but proliferating T cells expressed high levels of CD95, indicating a pro-apoptotic phenotype.
6529 19669608 These cells were cultured with cytokines GM-CSF, IL-4, and TNFalpha to induce their maturation.
6530 19669608 Phenotypically, FACS analysis showed that they expressed high levels of MHC II, CD11b, CD80, and CD86 antigen, and were negative for CD8alpha.
6531 19697061 A rapid increase of activated cells (CD25(+), CD44(high), and CD62L(low)) and production of both interferon-gamma and interleukin-4 was found in spleens of both malaria-infected mouse strains.
6532 19706340 Naloxone can improve the anti-tumor immunity by reducing the CD4+CD25+Foxp3+ regulatory T cells in BALB/c mice.
6533 19706340 Tumor and spleen CD4+CD25+Foxp3+ regulatory T lymphocytes, cytotoxic activity of the splenocytes, IFN-gamma and IL-4 secretion were assessed to describe the anti-tumor immune response.
6534 19706340 Our findings showed that co-administration of gp96 and naloxone has resulted in a significant reduction in CD4+CD25+Foxp3+ regulatory T cells in the spleen.
6535 19720368 The results showed that the group immunized with pVAX-MIC6 developed a high level of specific antibody responses against T. gondii lysate antigen (TLA), a strong lymphoproliferative response, and significant levels of IFN-gamma, IL-2, IL-4 and IL-10 production, compared with the other groups immunized with empty plasmid or phosphate-buffered saline, respectively.
6536 19725226 RNA electroporated CD40 ligand-activated B cells can induce cytotoxic T-lymphocyte response in vitro.
6537 19725226 C57BL/6 mouse spleen B cells were activated by anti-mouse CD40 antibody, recombinant interleukin-4, and cyclosporin A, and then electroporated with total RNA from Hepal-6 cells (Hepal-6 RNA-CD40mAb-B cells).
6538 19729088 Our results demonstrate that leptosome are better adjuvant than PC-liposomes as revealed by enhanced long term antibody response, lymphocyte proliferation and significant enhancement of both Th1 (IFN-gamma) and Th2 (IL-4 and IL-10) cytokines.
6539 19747578 The PBMC mRNA levels of IL4, RANTES, C3, IFN-gamma and methylmalonyl-CoA mutase (MUT) were analyzed at several days post-vaccination (dpi).
6540 19752029 The protection was associated with high levels of antigen-specific IFN-gamma and interleukin-17 (IL-17) and low IL-4 production.
6541 19752029 Moreover, different immunological parameters, such as IFN-gamma and IL-17 and tightly regulated IL-4 secretion, seem to contribute to the efficacy of this tuberculosis vaccine.
6542 19752029 The protection was associated with high levels of antigen-specific IFN-gamma and interleukin-17 (IL-17) and low IL-4 production.
6543 19752029 Moreover, different immunological parameters, such as IFN-gamma and IL-17 and tightly regulated IL-4 secretion, seem to contribute to the efficacy of this tuberculosis vaccine.
6544 19768458 Here, we report that a therapeutic whole cell vaccine formulated with IL-2 adsorbed onto aluminum hydroxide as cytokine-depot formulation elicits potent antitumor immunity and induces delayed tumor growth, control of tumor dissemination and longer survival in mice challenged with A20-lymphoma.
6545 19768458 Therapeutic vaccination induced higher numbers of tumor's infiltrating lymphocytes (CD4(+) and CD8(+) T cells and NK cells), and the production of IFN-gamma and IL-4 by intratumoral CD4(+) T cells.
6546 19768458 Both the A20-derived antigenic material and the IL-2 depot formulation were required for induction of an effective immune response that impacted on cancer progression.
6547 19768458 All mice receiving any form of IL-2, either as part of the vaccine or alone as control, showed higher numbers of CD4(+)CD25(+/high)Foxp3(+) regulatory T cells (Treg) in the tumor, which might have a role in tumor progression in these animals.
6548 19777806 And there was significant increase. of IFN-gamma and IL-4 contents in the supernatant of spleen cell culture in immunized group.
6549 19789093 Analysis of HBsAg-specific cytokines revealed that yeast-HBsAg is associated with production of both IFN-gamma and IL-4, but neither IFN-gamma nor IL-4 was detected in the HBsAg+alum-immunized group.
6550 19819209 Significant associations were observed between SNPs in the TNFalpha, IL-12B, IL-4Ralpha, and IL-10 genes and vaccine-specific immune responses (p<0.05).
6551 19819209 In addition, SNPs in the IL-1beta, TNFalpha, IL-2, IL-4, IL-10, IL-4Ralpha, and IL-12B genes were associated with variations in serum levels of immunoglobulins (IgG, IgA, IgM) and IgG isotypes (IgG1-IgG3) (p<0.05).
6552 19845795 The self-antigen, thyroglobulin, induces antigen-experienced CD4+ T cells from healthy donors to proliferate and promote production of the regulatory cytokine, interleukin-10, by monocytes.
6553 19845795 Whereas TT induced pro-inflammatory cytokines [interleukin-2 (IL-2)/interferon-gamma (IFN-gamma)/IL-4/IL-5], TG evoked persistent release of the regulatory IL-10.
6554 19845795 Some donors, however, also responded with late IFN-gamma production, suggesting that the regulation by IL-10 could be overridden.
6555 19845795 Although monocytes were prime producers of IL-10 in the early TG response, a few IL-10-secreting CD4(+) T cells, primarily with CD45RO(+) memory phenotype, were also detected.
6556 19863224 GM-CSF, IL-2, IL-6, TNF-alpha, IFN-gamma, IL-4, IL-8, IL-1b, IL-5, IL-10, IL-12, MIP-1b, IP-10 and Eotaxin were analyzed in a multiplex assay with a Luminex 100 instrument.
6557 19863224 CEA and TIMP-1 were analysed on ELISA platforms.
6558 19863224 Patients achieving stable disease showed increasing levels of plasma GM-CSF, TNF-alpha, IFN-gamma, IL-2, and IL-5.
6559 19863224 Patients with progressive disease showed significant increase in CEA and TIMP-1 levels, while patients with stable disease showed relatively unaltered levels.
6560 19878357 During the chronic infection, parasitism and inducible nitric oxide synthase (iNOS) as well as interleukin (IL)-4+ and, mainly, interferon (IFN)-gamma+ cells were more elevated in the heart tissue of pfp(-/-) mice.
6561 19878357 Higher levels of circulating NO and anti-parasite immunoglobulin (Ig)G2c and IgG3, paralleled by a prominent frequency of IFN-gamma+ and IL-10+ splenocytes, were present in pfp(-/-)-infected mice.
6562 19878357 Further, perforin deficiency resulted in lower activity of creatine kinase-muscle brain isoform (CK-MB) isoenzyme in serum and a more restricted connexin 43 loss, both of which are markers of the cardiomyocyte lesion.
6563 19906894 The patient exhibited a decreased level of expression of Fc-gammaR in monocytes (CD16, CD32, and CD64), along with increased levels of NK T cells (an increased CD3(+) CD16(+/-) CD56(+/-)/CD3(+) ratio), activated T cells (CD4(+) and CD8(+) cells), and B lymphocytes.
6564 19906894 Enhanced levels of plasmatic cytokines (interleukin-6 [IL-6], IL-17, IL-4, IL-5, and IL-10) as well as an exacerbated ex vivo intracytoplasmic cytokine pattern, mainly observed within NK cells (gamma interferon positive [IFN-gamma(+)], tumor necrosis factor alpha positive [TNF-alpha(+)], and IL-4 positive [IL-4(+)]), CD8(+) T cells (IL-4(+) and IL-5(+)), and B lymphocytes (TNF-alpha(+), IL-4(+), and IL-10(+)).
6565 19906894 The analysis of CD4(+) T cells revealed a complex profile that consisted of an increased frequency of IL-12(+) and IFN-gamma(+) cells and a decreased percentage of TNF-alpha(+), IL-4(+), and IL-5(+) cells.
6566 19906894 The patient exhibited a decreased level of expression of Fc-gammaR in monocytes (CD16, CD32, and CD64), along with increased levels of NK T cells (an increased CD3(+) CD16(+/-) CD56(+/-)/CD3(+) ratio), activated T cells (CD4(+) and CD8(+) cells), and B lymphocytes.
6567 19906894 Enhanced levels of plasmatic cytokines (interleukin-6 [IL-6], IL-17, IL-4, IL-5, and IL-10) as well as an exacerbated ex vivo intracytoplasmic cytokine pattern, mainly observed within NK cells (gamma interferon positive [IFN-gamma(+)], tumor necrosis factor alpha positive [TNF-alpha(+)], and IL-4 positive [IL-4(+)]), CD8(+) T cells (IL-4(+) and IL-5(+)), and B lymphocytes (TNF-alpha(+), IL-4(+), and IL-10(+)).
6568 19906894 The analysis of CD4(+) T cells revealed a complex profile that consisted of an increased frequency of IL-12(+) and IFN-gamma(+) cells and a decreased percentage of TNF-alpha(+), IL-4(+), and IL-5(+) cells.
6569 19923568 The relationship between immune responses and disease severity within the PB group was investigated more closely; significant positive correlations were observed between disease severity and both the CD8(+) population in the circulating blood and the expression of interleukin-4 mRNA in antigen-stimulated blood samples ex vivo.
6570 19930042 Immunization of mice with these altered peptide ligands emulsified in complete Freund's adjuvant induced both interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) responses compared with only IFN-gamma responses induced to the native MBP(87-99) peptide.
6571 19930042 It was of interest that [R(91), A(96)]MBP(87-99) conjugated to reduced mannan induced 70% less IFN-gamma compared with the native MBP(87-99) peptide.
6572 19930042 However, [A(91), A(96)]MBP(87-99) conjugated to reduced mannan did not induce IFN-gamma-secreting T cells, but elicited very high levels of interleukin-4 (IL-4).

6575 19930042 However, [A(91), A(96)]MBP(87-99) conjugated to reduced mannan did not induce IFN-gamma-secreting T cells, but elicited very high levels of interleukin-4 (IL-4).
6576 19933862 Analysis of the cellular immune responses of ubiquitin-conjugated ORFF (UBQ-ORFF) DNA-immunized, uninfected BALB/c mice demonstrated that the vaccine induced enhanced IFN-gamma-producing CD4(+) and CD8(+) T cells compared with nonubiquitinated ORFF DNA vaccine.
6577 19933862 Higher levels of IL-12 and IFN-gamma and the low levels of IL-4 and IL-10 further indicated that the immune responses with UBQ-ORFF were mediated toward the Th1 rather than Th2 type.
6578 19933862 UBQ-ORFF DNA-immunized and -infected mice showed a significant increase in IL-12 and IFN-gamma and significant down-regulation of IL-10.
6579 20005853 Unexpectedly, vaccinated mice developed larger cutaneous lesions, harbored significantly more parasites, and cells from lymph nodes produced higher amounts of parasite-specific IL-4, IL-10 and IFN-gamma in cultures.
6580 20013309 Moreover, the B. abortus S-19 vaccinated mice showed highest production of IL-4 and IFN-gamma.
6581 20031926 The tumor necrosis factor-alpha response for most of the fractions did not significantly differ in the tested groups, and the interleukin-4 response was below the detectable range for all fractions and both study groups.
6582 20032499 WAS(-/-) CD4(+) T cells mediated protective T-helper 1 (Th1) responses to Leishmania major in vivo, but were unable to support Th2 immunity to Nippostrongylus brasiliensis or L major.
6583 20032499 WAS(-/-) CD4(+) T cells up-regulated IL-4 and GATA3 mRNA and secreted IL-4 protein during Th2 differentiation.
6584 20032499 WAS(-/-) Th2s failed to produce IL-4 protein on restimulation despite elevated IL-4/GATA3 mRNA.
6585 20032499 Moreover, dominant-negative WASp expression in WT effector T cells blocked IL-4 production, but had no effect on IFNgamma.

6593 20032499 Moreover, dominant-negative WASp expression in WT effector T cells blocked IL-4 production, but had no effect on IFNgamma.
6594 20039802 Healthy donor plasma had high immunoglobulin G titers (median, 1:51,200) and lower immunoglobulin A (median, 1:3,200) and immunoglobulin E (median, 1:128) titers to rAls3p-N by enzyme-linked immunosorbent assay. rAls3p-N stimulated interferon gamma (IFN-gamma) and interleukin (IL)-17, but not IL-4, from donor lymphocytes by enzyme-linked immunosorbent spot assay and IL-12 p70, IFN-gamma, IL-17, and IL-10 by cytometric bead array.
6595 20053873 Mice born to immunized mothers produced higher titers of PspA-specific antibodies in the blood and mucosa and greater numbers of PspA-specific interleukin-4 (IL-4)-secreting cells than mice born to naïve mothers.
6596 20056184 Splenocytes from i.n. immunized mice produced high level of IFN-gamma but not IL-4 in response to Leish-111f.
6597 20056331 Changes in the levels of rabbit interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor-alpha (TNFalpha), and interferon-gamma (IFNgamma) mRNA were determined.
6598 20056331 All cytokine mRNAs were found at detectable levels; however, the levels of IFNgamma, TNFalpha, IL-2 and IL-10 were significantly higher in the vaccinated group compared to the non-vaccinated group.
6599 20060944 Of note, PCPP administration resulted in mixed Th1 and Th2 type responses (i.e., high levels of IgG2a and IgG1 as well as IFN-gamma and IL-4).
6600 20072623 After in vitro stimulation, spleen cells of immunized mice produce high levels of Th1 cytokines and show a prominent mRNA expression of the Th1 transcription factor T-bet, in detriment of the Th2 transcription factor GATA-3.
6601 20072623 Following R. equi challenge, a high H2O2, NO, IL-12, and IFN-gamma content is detected in the organs of immunized mice.
6602 20072623 On the other hand, TNF-alpha and IL-4 levels are markedly lower in the organs of vaccinated mice, compared with the non-vaccinated ones.
6603 20072623 A greater incidence of CD4+ and CD8+ T cells and B lymphocytes is verified in vaccinated mice.
6604 20072623 However, there is no difference between vaccinated and non-vaccinated mice in terms of the frequency of CD4+CD25+Foxp3+ T cells.
6605 20080728 Undetectable levels of interferon-gamma, IL-2, and IL-4 in cultures of peptide-challenged splenocytes from immunized mice suggested that the antibody responses did not involve significant T cell help.
6606 20087984 Moreover, 1 significantly promoted the production of Th1 (IL-2 and IFN-gamma) and Th2 (IL-4 and IL-10) cytokines from splenocytes in the HBsAg-immunized mice (P<0.001).
6607 20116467 SL-applied CTB enhanced the production of interleukin-4 and interferon-gamma from stimulated CD4+ T cells.
6608 20116467 Moreover, interferon-gamma-producing CD8+ T cell responses were increased 1.7-fold after co-treatment with SL CTB and HPV16L1.
6609 20116862 The activation markers included major histocompatibility complex class II (MHC II), intracellular interferon gamma (IFN-gamma) and interleukin 4 (IL-4).
6610 20116862 Following EHV-1 stimulation, the MHC II expression index (EI) increased significantly in CD2+CD4+CD8- and CD2+CD4-CD8+ subsets of the infected group.
6611 20116862 At 4 days after incubation, the non-antigen stimulated CD2+CD4-CD8- subset of the infected group expressed a high percentage (61.1%) of MHC II.
6612 20116862 The IFN-gamma EI was significantly higher in infected foals in all major T cell subsets (CD2+) while only the CD2+CD4+CD8- subset showed a significant increase in intracellular IL-4 EI.
6613 20116862 The high MHC II expression in the CD2+CD4-CD8- subset suggests that this T cell subset may represent a gammadelta TCR repertoire and thereby plays an important role as antigen presenting cells in the horse, as reported in other species.
6614 20116862 The activation markers included major histocompatibility complex class II (MHC II), intracellular interferon gamma (IFN-gamma) and interleukin 4 (IL-4).
6615 20116862 Following EHV-1 stimulation, the MHC II expression index (EI) increased significantly in CD2+CD4+CD8- and CD2+CD4-CD8+ subsets of the infected group.
6616 20116862 At 4 days after incubation, the non-antigen stimulated CD2+CD4-CD8- subset of the infected group expressed a high percentage (61.1%) of MHC II.
6617 20116862 The IFN-gamma EI was significantly higher in infected foals in all major T cell subsets (CD2+) while only the CD2+CD4+CD8- subset showed a significant increase in intracellular IL-4 EI.
6618 20116862 The high MHC II expression in the CD2+CD4-CD8- subset suggests that this T cell subset may represent a gammadelta TCR repertoire and thereby plays an important role as antigen presenting cells in the horse, as reported in other species.
6619 20130127 The cytokines studied included interleukin-2 (IL-2), IL-4, and IL-10.
6620 20130127 The VOC group was notable for remarkably elevated levels of IL-4, among the three cytokines tested, compared with those for the SCD and NHC groups.
6621 20130127 Patients with VOC also differed from stable SCD patients and NHC by having notably lower IL-10 levels, as well as the lowest ratio of CD4(+) to CD8(+) T cells (0.7).
6622 20130127 The patterns of the proinflammatory cytokine IL-2 did not differ between VOC and stable SCD patients, but NHC had significantly lower IL-2 levels than both the VOC and SCD groups.
6623 20130127 The cytokines studied included interleukin-2 (IL-2), IL-4, and IL-10.
6624 20130127 The VOC group was notable for remarkably elevated levels of IL-4, among the three cytokines tested, compared with those for the SCD and NHC groups.

6626 20130127 The patterns of the proinflammatory cytokine IL-2 did not differ between VOC and stable SCD patients, but NHC had significantly lower IL-2 levels than both the VOC and SCD groups.
6627 20132920 The antigen-specific T cell immune response elicited both Th1 and Th2 cytokines including high titers of IFN-gamma, IL-2 and IL-4, and drove a Th1 isotype-switched antibody response.
6628 20132994 Diminished CD4+/CD25+ T cell and increased IFN-gamma levels occur in dogs vaccinated with Leishmune in an endemic area for visceral leishmaniasis.
6629 20132994 Cytokines IFN-gamma, IL-4 and TNF-alpha were measured in culture supernatant and CD4+/CD25+ and CD8+/CD25+ T cell presence was determined.
6630 20132994 Analysis of the data indicated that the vaccine conferred humoral responses (100%) against both antigens and cellular immunity to FML (85%) and total antigen (80%), the supernatant of cultured cells stimulated with TAg and FML showed an increase in IFN-gamma (P<0.05), and the vaccine reduced CD4+/CD25+ T cell presence compared to that observed before vaccination.
6631 20136620 In vitro, AcF1 was shown to activate total splenocytes, CD4+ T cells, and B cells, inducing remarkable increases in CD69 expression, profound proliferation, and increased IL-4 and IFN-gamma expression by the naïve splenic cells in a concentration-dependent manner.
6632 20145701 Thus, cell cultures established from spleens and the draining lymph node of the secondary site of infection produced high levels of parasite specific IFN-gamma in the absence of IL-4 and IL-10 cytokine production.
6633 20153353 The mRNA expression levels of interleukin-2 (IL-2), interferon-gamma (IFN-gamma), interleukin-4 (IL-4), and interleukin-12 (IL-12) were determined using a semi-quantitative RT-PCR assay.
6634 20153353 The rPLF administration significantly increased chicken intestinal villous lengths and also enhanced the expression of IFN-gamma and IL-12 in chicken T lymphocytes.
6635 20153792 Furthermore, immunohistochemical studies revealed that the Prx-immunized group exhibited reduced infiltration of CD4(+), CD8(+), IFN-gamma(+) and TCR(+) (p<0.05); and CD2(+) and IL-4(+) (p<0.001) in hepatic lesions.
6636 20177910 Levels of IgG antibody, gamma-interferon (IFN-gamma), interleukin-2 (IL-2), interleukin-4, and interleukin-10 were detected.
6637 20177910 The high level of IFN-gamma, IL-2, and IgG antibody indicated that mice vaccinated with recombinant pVAX-MIC8 plasmid could elicit strong cellular and humoral immune responses and showed a significantly increased survival time (10.3 +/- 0.9 days) compared with control mice which died within 5 days of challenge infection.
6638 20195541 Individual, yet overlapping peptides, 15 amino acids in length revealed residues 199 to 246 of PspA (PspA(199-246)) consistently caused the greatest IFN-gamma, IL-2, IL-5 and proliferation as well as moderate IL-10 and IL-4 responses by ex vivo stimulated splenic and CLN CD4(+) T cells isolated from S. pneumonia strain EF3030-challeged F(1) (B6xBALB/c) mice.
6639 20200251 We previously developed recombinant RSV vectors expressing IFN-gamma and interleukin-4 (IL-4) that allow us to explore the role of these key Th1 and Th2 cytokines during infection.
6640 20219540 Both IFN-gamma and IL-4 in chicken's lymphocytes were produced by this strategy.
6641 20219669 Differences in cytokines production were found for IL-10, IL-4, TNF-alpha, and Arginase-1, which, in some conditions, resulted higher in r-BCG as compared to wt BCG-immunised mice.
6642 20219878 Compared to the levels in the controls, the levels of alpha interferon (IFN-alpha), interleukin-1beta (IL-1beta), IL-12, and IFN-gamma were increased in TBLN homogenates from PRV-infected pigs at 1 dpi, whereas the IL-18 levels were decreased from 3 to 6 dpi.
6643 20219878 The protein levels of IL-4 and IL-10 did not differ between the controls and the PRV-infected pigs at any time point.
6644 20219878 Flow cytometric analysis of TBLN homogenates of PRV-infected pigs and the controls revealed increases in the percentages of B cells at 6 dpi, CD4(+) cells at 14 dpi, and CD25 expression in TBLN homogenates (in the total mononuclear fraction and on B cells) in the PRV-infected pigs.
6645 20221274 The PBSCs were cultured in the X-VIVO 20 medium supplemented with the Flt-3 Ligand (FL), GM-CSF, IL-4 and TNF-alpha for 12 days.
6646 20333282 In all experiments, an early relatively high level of IFN-gamma and IgG2a during the acute phase of the infection, and later elevation of IL-4 and IgG1, suggested that there was a sequential Th1/Th2 response.
6647 20381647 Lactic acid bacteria enhance autophagic ability of mononuclear phagocytes by increasing Th1 autophagy-promoting cytokine (IFN-gamma) and nitric oxide (NO) levels and reducing Th2 autophagy-restraining cytokines (IL-4 and IL-13) in response to Mycobacterium tuberculosis antigen.

6689 20394723 The studies showed that PTD-HBcAg not only induced significantly higher antibody responses, but also increased production of cytokine (IFN-gamma, IL-2, IL-4 and IL-10) compared to HBcAg alone and PBS.
6690 20394723 Moreover, PTD-HBcAg fusion protein increased significantly the percentages of IFN-gamma+CD8+ T cells and HBcAg-specific (CTL) responses.
6691 20404924 Further, circulating levels of IFN-gamma, TNF-alpha, IL-10, IL-6, IL-4 and IL-2 were analysed in VL patients (n = 29) by Cytometric Bead Array to evaluate correlation with parasitic load.
6692 20406664 Increased anti-GAD65 IgG1, serum IgA and unchanged IgG2a antibodies titers; together with an increase of IL-4, IL-10 production and a decrease of IFN-gamma production suggested possible activation of GAD65-specific Th2 immune responses.
6693 20421972 VEE/SIN-H-induced T cells produced IFN-gamma and IL-4 both spontaneously ex vivo and after stimulation, while FI-MV-induced T cells produced IL-4 only after stimulation.
6694 20434553 Splenocytes were separated for detection of lymphocyte proliferation in responses to concanavalin A (Con A), lipopolysaccharide (LPS) and OVA, and mRNA expression of Th1 cytokines (IFN-gamma and IL-12), Th2 cytokines (IL-10 and IL-5) and transcription factors T-bet/GATA-3 (Th1/Th2 switcher).
6695 20434553 In addition, up-regulated T-bet/GATA-3 together with significantly increased mRNA expression of IL-4, IL-10, IFN-gamma and IL-12 by splenocytes, as well as the proliferative responses of splenocytes to Con A, LPS and OVA were observed in paclitaxel-adjuvanted groups.
6696 20434553 Incubation of a murine macrophage-like cell line with paclitaxel significantly increased TNF-alpha and -10 released from the cells and expression of microRNAs such as miR-155, miR-147, miR-146a and miR-132.
6697 20450288 The cytokine measurement profile of IFN-gamma, TNF-alpha, IL-2, IL-4 and IL-10 in culture supernatants of cells primed with peptide antigens in microparticles co-encapsulating CpG ODN showed higher levels of IFN- gamma followed by TNF-alpha and IL-2, with relatively low levels of IL-4 and IL-10.
6698 20452455 We herein characterized the cytokines response ESP, e.g., SG3PDH, 14-3-3-like protein, TPX, and calpain induce in the natural context of infection, and defined the global cytokine profile conducive to effective schistosome larvae killing.
6699 20452455 Recombinant SG3PDH was the only test ESP to additionally activate SC from S. mansoni-infected BALB/c mice to release higher IL-4 levels than unstimulated SC and mediate significant (P < 0.0001) in vitro attrition of lung-stage larvae.
6700 20471443 Incorporation of CD40 ligand into SHIV virus-like particles (VLP) enhances SHIV-VLP-induced dendritic cell activation and boosts immune responses against HIV.
6701 20471443 Engagement of CD40 with CD40L induces dendritic cell (DC) maturation and activation, thereby promoting immune responses.
6702 20471443 We found that CD83, CD40, and CD86 were significantly up-regulated and significantly increased cytokines production were observed after hCD40L/SHIV-VLP treatment in human CD14(+) monocyte-derived DCs as compared to SHIV-VLP treatment.
6703 20471443 Mice immunized with mCD40L/SHIV-VLP showed more than a two-fold increase in HIV Env-specific IgG antibody production, an increase in SIV Gag and HIV Env-specific IFN-gamma and IL-4 producing cells, and an increase in HIV Env-specific cytotoxic activity compared to that in SHIV-VLP immunized mice.
6704 20471443 Furthermore, multifunctional CD4(+) Th1 cells, which simultaneously produce IFN-gamma, IL-2 and TNF-alpha triple cytokines, and CD8(+) T-cells, which produce IFN-gamma were elevated in the mCD40L/SHIV-VLP immunized group.
6705 20471443 Therefore, incorporation of CD40L into VLP may represent a novel strategy to develop effective HIV vaccines.
6706 20472030 In vitro, soluble proteases isolated from LaAg (LaSP-Sol) directly activated IL-4, IL-10 and TGF-beta production by immune cells.
6707 20483237 In fish, prior to pufferfish (Fugu rubripes and Tetraodon nigroviridis) and zebrafish (Danio rerio) genome sequencing, only a handful of cytokines like IL-1beta, TNF-alpha, TGFbeta, some CXC (including IL-8) and CC chemokine genes were identified.
6708 20483237 Pro-inflammatory cytokines like TNF's, IL-6 and IL-17 family have been cloned.
6709 20483237 Among the T(H)1 type interleukins, IL-2, IL-15, IL-12alpha, IL-12beta, IL-18 have been cloned.
6710 20483237 Among IL-10 and its family members, IL-10, IL-19/20, IL-22 and IL-26 have been discovered.
6711 20483237 However, T(H)2 cytokines (IL-4, IL-5 and IL-13), IL-3, IL-7 and IL-9 are yet to be discovered from fish.
6712 20488263 This FMIA simultaneously detects innate (IL-1 beta, IL-8, IFN-alpha, TNF-alpha, IL-12), regulatory (IL-10), Th1 (IFN-gamma) and Th2 (IL-4) cytokines.
6713 20495560 Here we demonstrate that cysteine protease-induced T(H)2 responses occur via 'cooperation' between migratory dermal dendritic cells (DCs) and basophils positive for interleukin 4 (IL-4).
6714 20495560 ROS orchestrated T(H)2 responses by inducing oxidized lipids that triggered the induction of thymic stromal lymphopoietin (TSLP) by epithelial cells mediated by Toll-like receptor 4 (TLR4) and the adaptor protein TRIF; by suppressing production of the T(H)1-inducing molecules IL-12 and CD70 in lymph node DCs; and by inducing the DC-derived chemokine CCL7, which mediated recruitment of IL-4(+) basophils to the lymph node.
6715 20495560 Here we demonstrate that cysteine protease-induced T(H)2 responses occur via 'cooperation' between migratory dermal dendritic cells (DCs) and basophils positive for interleukin 4 (IL-4).

6717 20502628 The 40K-OMP-specific CD4(+) T cells induced by oral 40K-OMP plus CpG ODN produced both Th1 (IFN-gamma) and Th2 (IL-4) cytokines.
6718 20502628 Furthermore, increased frequencies of CD11c(+)B220(+) DCs and CD11c(+)CD11b(+) DCs with up-regulated expression of CD80, CD86, CD40 and MHC II molecules were noted in spleen, Peyer's patches and cervical lymph nodes.
6719 20525889 Germinal center T follicular helper cell IL-4 production is dependent on signaling lymphocytic activation molecule receptor (CD150).
6720 20525889 Signaling lymphocytic activation molecule (SLAM)-associated protein (SAP [SH2D1A]) expression in CD4 T cells is essential for GC development.

6739 20544406 Co-administration of GP96 and Her2/neu DNA vaccine in a Her2 breast cancer model.
6740 20544406 In this study, animals with Her2-expressing tumors were vaccinated by co-administration of GP96+ Her2/neu DNA vaccines.
6741 20544406 Analyses of the immune response, 2 weeks after the last immunization revealed decreased CD4+ CD25+ Foxp3+ naturally occurring regulatory T cells (Tregs) at the tumor site and increased IFN-γ/IL-4 level.
6742 20562818 Mice immunized with low dose of Alum-ALM mixed with either BCG or low M. vaccae showed a significantly higher IFN-gamma production and a lower IL-4 level and a significantly lower parasite burden compared to the control PBS injected group.
6743 20575435 The effect was determined in the form of protective anti-IBDV VP2 titers, antibodies (IgG1 and IgG2a), lymphocyte proliferation, the levels of interferon-gamma and interleukin-4 cytokines, and challenge experiment.
6744 20575435 The seem result elicited from cytokines ELISA test, secretion of both of Th1 (gamma-IFN) and Th2 (IL-4) were induced by the rVP2-IL-2 fusion protein.

6747 20599915 Ursolic acid isolated from Uncaria rhynchophylla activates human dendritic cells via TLR2 and/or TLR4 and induces the production of IFN-gamma by CD4+ naïve T cells.
6748 20599915 The expression levels of CD1a, CD80, CD83, CD86, HLA-DR and CCR7 on Ursolic acid-primed dendritic cells was slightly enhanced.
6749 20599915 Moreover, Ursolic acid-primed dendritic cells expressed levels of mRNA coding for both TLR2 and TLR4.
6750 20599915 The majority of cells produced considerable interferon-gamma (IFN-gamma), but also small amounts of interleukin (IL-4)-4.
6751 20599915 Ursolic acid-primed dendritic cells have an intermediate migratory capacity towards CCL19 and CCL21.
6752 20599915 These results suggest that Ursolic acid modulates human dendritic cells function in a fashion that favors Th1 polarization via the activation of IL-12p70 dependent on TLR2 and/or TLR4, and may be used on dendritic cells-based vaccines for cancer immunotherapy.
6753 20601076 Mice vaccinated with parasite ribosomal proteins purified from Leishmania infantum plus saponin showed a specific production of IFN-γ, IL-12 and GM-CSF after in vitro stimulation with L. infantum ribosomal proteins.
6754 20601076 In both models, protection was correlated to an IL-12-dependent production of IFN-γ by CD4(+) and CD8(+) T cells that activate macrophages for the synthesis of NO.
6755 20601076 In the protected mice a decrease in the parasite-mediated IL-4 and IL-10 responses was also observed.
6756 20601170 High ratios of IFN-gamma/IL-4 were shown in mice inoculated by strain of Dehloran (3.17) and Damghan (2.66), but not in mice infected by other strains, 8 weeks post-infection.
6757 20601170 The highest and lowest ratios of CD4(+)/CD8(+) T cells were found in LN cells of mice infected with Kashan (1.82) and Dehloran (1.00) strains, respectively.
6758 20601170 Results indicate that the lowest and intermediate loads of parasites induced by Damghan and Dehloran strains along with higher ratio of IFN-gamma/IL-4 produced by both strains in LN of inoculated mice suggest that these strains have the capacity to shift the immune responses to a predominant Th1 response after 8 weeks infection in BALB/c mice and might be the ideal strains for vaccine studies and development of candidate vaccine against leishmaniasis.
6759 20601170 High ratios of IFN-gamma/IL-4 were shown in mice inoculated by strain of Dehloran (3.17) and Damghan (2.66), but not in mice infected by other strains, 8 weeks post-infection.
6760 20601170 The highest and lowest ratios of CD4(+)/CD8(+) T cells were found in LN cells of mice infected with Kashan (1.82) and Dehloran (1.00) strains, respectively.
6761 20601170 Results indicate that the lowest and intermediate loads of parasites induced by Damghan and Dehloran strains along with higher ratio of IFN-gamma/IL-4 produced by both strains in LN of inoculated mice suggest that these strains have the capacity to shift the immune responses to a predominant Th1 response after 8 weeks infection in BALB/c mice and might be the ideal strains for vaccine studies and development of candidate vaccine against leishmaniasis.
6762 20635971 Moreover, treatment of tuberculous mice with Ag85AB-CpG-DDA induced higher production of type-I cytokines, generated more CD44-positive T cells and suppresses secretion of IL-4 as compared with untreated animals.
6763 20638483 Geometric mean values of IL-12, IFN-γ, TNF-α, IL-4 and IL-10 in PBMC culture supernatants of P. vivax exposed individuals were 182.02, 60.3, 62.84, 196.01 and 177.17 pg/ml against PvTRAg 35.2 and 185.27, 58.15, 64.56, 142.01 and 157.2 pg/ml against PvTRAg 80.6 showing mixed immune response with distinct biased towards anti-inflammatory Th2 phenotype.
6764 20696860 The differentiation of CD4(+) T cells into the Th2 subset is controlled by the transcription factor GATA-3.
6765 20696860 We show in this study that IL-4 stimulation induces GATA-3 mRNA upregulation, but the level of GATA-3 protein induced is insufficient for Th2 differentiation.
6766 20696860 The levels of GATA-3 protein and Th2 differentiation are enhanced by concomitant TCR signaling through the PI3K/mammalian target of rapamycin pathway.
6767 20696860 The PI3K-mediated increase in GATA-3 protein occurs without increasing the GATA-3 mRNA level.
6768 20696860 Rather, TCR signaling through PI3K specifically enhances the translation rate of GATA-3 without affecting the protein stability.
6769 20696860 Thus, TCR signaling through PI3K may play a critical role in Th2 differentiation by the specific enhancement of GATA-3 translation.
6770 20703434 Differential effects of cytokines IFN-gamma and IL-4 in the development of inflammatory macrophages, and the distinct developmental pathways of proinflammatory or tissue-repair-associated monocytes suggest that controlling the activity of these monocytes could be part of an immune intervention strategy to prevent T1D.
6771 20709105 Expression of selected gene groups was tested via qPCR at 7 different time-points: cytokines (IL-2, IFN-γ, IL-4, IL-6, and IL-10), type I interferons (IFN-α4, IFN-α11, IFN-α12, and IFN-β), toll-like receptors (TLR2, TLR3, TLR7, and TLR9), iNOS and CCR7.
6772 20709105 Intranasally administered DBF and the mixture of virus+DBF induced an elevated expression of IFN-γ, IL-6 and IL-10 cytokines, type I interferons, iNOS, and pDC markers in NALT.
6773 20732465 Increased frequency of IL-10(+) monocytes was observed at day 15 and day 30, and decreased percentage of IL-4(+) NK-cells were detected at day 7, day 15 and day 30.
6774 20732465 Time-dependent and oscillating cytokine pattern was observed in CD4(+) T-cells, with low percentage of IL-12(+), IL-4(+) and IL-10(+) cells at day 7 and increased frequency of TNF-α(+) cells at day 15 besides IFN-γ(+) and IL-5(+) cells at day 15 and day 30.
6775 20732465 Later changes with increased percentage of IL-12(+) and IL-5(+)CD8(+) T-cells were observed at day 30.
6776 20732465 Increased frequency of IL-10(+) monocytes was observed at day 15 and day 30, and decreased percentage of IL-4(+) NK-cells were detected at day 7, day 15 and day 30.
6777 20732465 Time-dependent and oscillating cytokine pattern was observed in CD4(+) T-cells, with low percentage of IL-12(+), IL-4(+) and IL-10(+) cells at day 7 and increased frequency of TNF-α(+) cells at day 15 besides IFN-γ(+) and IL-5(+) cells at day 15 and day 30.
6778 20732465 Later changes with increased percentage of IL-12(+) and IL-5(+)CD8(+) T-cells were observed at day 30.
6779 20738198 All tachyzoite and antigen preparations at high doses stimulated high levels of interleukin (IL) -12, interferon (IFN) -gamma, and tumor necrosis factor (TNF) -alpha, except for heat-killed tachyzoites and sNcAg, which induced moderate level of IL-12 and very low levels of IFN-gamma and TNF-alpha.
6780 20738198 In general, whole N. caninum tachyzoites were more effective in inducing IL-12, IFN-gamma, and TNF-alpha than the lysate antigen preparations.
6781 20738198 It appears that the heat-killed N. caninum tachyzoites were less potent in eliciting IFN-gamma or IL-10, but more effective in inducing IL-4.
6782 20812236 The DEC-targeted LcrV induced polarized Th1 immunity, whereas DCIR2-targeted LcrV induced fewer CD4(+) T cells secreting IFN-γ, but higher IL-4, IL-5, IL-10, and IL-13 production.
6783 20816019 The immunological consequences of the treatment were evaluated with plasma- and serum-levels of inflammatory and non-inflammatory markers (the following 10 cytokines: GM-CSF, INF-gamma, IL-1beta, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, and TNF-alpha, and in addition the inflammatory chemokines MIP-1beta, Eotaxin and IP-10) and biomarkers CEA and TIMP-1.
6784 20816019 These analyses showed that the vaccine induced increasing levels of Th1 cytokines such as GM-CSF, TNF-alpha, IFN-gamma, and IL-2 in patients achieving stable disease.
6785 20816019 Patients with progressive disease had increasing levels of CEA and TIMP-1, while patients achieving stable disease maintained relatively stable levels.
6786 20835620 The nature of the local immune response was assessed by examining the distribution of CD2+, CD4+, CD8+ and γ´+ T lymphocytes along with IgG+, IL-4+ and IFN-γ+ cells in the liver and hepatic lymph nodes (HLN).
6787 20835620 Immunization with rSm14 in Quil A adjuvant induced a reduction in gross hepatic lesions of 56.6% (p < 0.001) and reduced hepatic and HLN infiltration of CD2+, CD4+, CD8+ and γ´+ T lymphocytes as well as IL-4+ and IFN-γ+ cells (p < 0.05).
6788 20835620 The nature of the local immune response was assessed by examining the distribution of CD2+, CD4+, CD8+ and γ´+ T lymphocytes along with IgG+, IL-4+ and IFN-γ+ cells in the liver and hepatic lymph nodes (HLN).
6789 20835620 Immunization with rSm14 in Quil A adjuvant induced a reduction in gross hepatic lesions of 56.6% (p < 0.001) and reduced hepatic and HLN infiltration of CD2+, CD4+, CD8+ and γ´+ T lymphocytes as well as IL-4+ and IFN-γ+ cells (p < 0.05).
6790 20838241 Vaccinations targeting extracellular superoxide dismutase 1 (SOD1) mutants are beneficial in mouse models of amyotrophic lateral sclerosis (ALS).
6791 20838241 The vaccines potentiated TH2 deviation in the spinal cord as determined by the ratio of interleukin-4 to interferon-γ (IFNγ) or tumor necrosis factor and induced C1q deposition around motor neurons.
6792 20838241 On the other hand, the sera from G93A SOD1-vaccinated mice showed higher IFNγ or tumor necrosis factor and yielded a lower IgG1/IgG2c ratio than the sera from WT-apo-vaccinated mice.
6793 20850939 Protective immune responses induced by in ovo immunization with recombinant adenoviruses expressing spike (S1) glycoprotein of infectious bronchitis virus fused/co-administered with granulocyte-macrophage colony stimulating factor.
6794 20850939 In the present report, the recombinant adenoviruses expressing chicken granulocyte-macrophage colony stimulating factor (GM-CSF) and S1 gene of nephropathogenic IBV were constructed and characterized.
6795 20850939 Moreover, the fusion of the GM-CSF markedly increased spleen cell proliferation and IFN-γ production while mild increased in IL-4 production, which demonstrated the enhancement of cell-mediated immune responses.
6796 20870310 However, only the chimeric vaccine was able to enhance Th1/Th2 cytokine secretion in response to class II GAG peptide and to enhance IL-4-secreting cells against GAG peptides and p24 protein stimuli.
6797 20883735 After administration into BALB/c mice, all three vectors elicited HA-specific humoral (IgG1, IgG2a and hemagglutination inhibition titers), mucosal (IgA titers) and cellular (interferon (IFN)-γ and IL-4 producing T cells and IFN-γ(+)/CD8(+) T cells) immune responses.
6798 20926697 Simultaneous measurement of antigen-stimulated interleukin-1 beta and gamma interferon production enhances test sensitivity for the detection of Mycobacterium bovis infection in cattle.
6799 20926697 In order to identify cytokines that may be useful as candidates for inclusion in diagnostic tests for Mycobacterium bovis infection in cattle, we compared the levels of gamma interferon (IFN-γ), interleukin 1β (IL-1β), IL-4, IL-10, IL-12, macrophage inflammatory protein 1β (MIP-1β), and tumor necrosis factor alpha (TNF-α) in whole-blood cultures from tuberculosis (TB) reactor animals or TB-free controls following stimulation with M. bovis-specific antigens (purified protein derivative from M. bovis [PPD-B] or ESAT-6/CFP-10).
6800 20944999 Antigenic extracts of Leishmania braziliensis and Leishmania amazonensis associated with saponin partially protects BALB/c mice against Leishmania chagasi infection by suppressing IL-10 and IL-4 production.
6801 20944999 This protection was associated with a suppression of both interleukin (IL)-10 and IL-4 cytokines by spleen cells in response to L. chagasi antigen.
6802 20944999 Antigenic extracts of Leishmania braziliensis and Leishmania amazonensis associated with saponin partially protects BALB/c mice against Leishmania chagasi infection by suppressing IL-10 and IL-4 production.
6803 20944999 This protection was associated with a suppression of both interleukin (IL)-10 and IL-4 cytokines by spleen cells in response to L. chagasi antigen.
6804 20955167 Additionally, the different epitopes elicited various CD4(+) T-cell responses, as shown by the resulting lymphocyte proliferation and varied IFN-γ and IL-4 levels determined by EILSPOT; however, each could be distinctly recognized by sera derived from malaria patients.
6805 21030562 We have completed a phase 1 study in which patients with multiple myeloma underwent serial vaccination with the DC/multiple myeloma fusions in conjunction with granulocyte-macrophage colony-stimulating factor.
6806 21030562 DCs were generated from adherent mononuclear cells cultured with granulocyte-macrophage colony-stimulating factor, interleukin-4, and tumor necrosis factor-α and fused with myeloma cells obtained from marrow aspirates.
6807 21030562 Vaccination resulted in the expansion of circulating CD4 and CD8 lymphocytes reactive with autologous myeloma cells in 11 of 15 evaluable patients.
6808 21035197 No specific increase in cell-mediated immune (CMI) response was induced by the vaccine as determined by EIV-specific lymphoproliferation and the detection of EIV-specific IFNγ(+) CD5(+)T cells, IFNγ, IL-2, IL-4 and IL-13 mRNA expression.
6809 21035507 Cell proliferation, cytokines (IL-2, IFN-γ and IL-4), and lymphocyte sub-populations (CD4/CD8, CD3 and CD19) were determined in splenocytes from mice administered subcutaneously with test substances.
6810 21035507 In these cells CD4/CD8 derived IFN-γ release was also determined.
6811 21039466 Immature MoDCs were generated by incubating peripheral blood monocytes with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4.
6812 21039466 MoLCs showed a lower expression of CD83, CD86, HLA-DR and CCR7 compared with MoDCs, regardless of their maturational status.
6813 21039466 Both immature and mature MoLCs secreted higher quantities of IL-23 compared with MoDCs and this finding correlated with a higher secretion of IL-17 in co-culture of MoLCs with allogeneic CD4(+) T cells.
6814 21039466 Mature MoLCs, which produced higher levels of IL-12 and lower levels of IL-10 compared with mature MoDCs, were more potent at inducing interferon-γ (IFN-γ) production by CD4(+) T cells in the co-culture system.
6815 21039737 To compare SV1 and SV2 (200 μg F1+100 μg rV270) with live attenuated vaccine EV76, antibody responses, protective efficacy, cytokines (IFN-γ, TNF-α, IL-2, IL-4, IL-10 and IL-12) production, CD4/CD8 ratio and CD69(+) T-cell activation marker were determined in sera of the immunized Chinese-origin rhesus macaques, Macaca mulatta.
6816 21039737 There were no statistical changes for CD4/CD8 ratios, IL-4 and CD69 levels between the three-vaccine immunized groups.
6817 21039737 To compare SV1 and SV2 (200 μg F1+100 μg rV270) with live attenuated vaccine EV76, antibody responses, protective efficacy, cytokines (IFN-γ, TNF-α, IL-2, IL-4, IL-10 and IL-12) production, CD4/CD8 ratio and CD69(+) T-cell activation marker were determined in sera of the immunized Chinese-origin rhesus macaques, Macaca mulatta.
6818 21039737 There were no statistical changes for CD4/CD8 ratios, IL-4 and CD69 levels between the three-vaccine immunized groups.
6819 21057930 The output of an ELISpot assay is a formation of colored spots which appear at the sites of cells releasing cytokines, with each individual spot representing a single cytokine-releasing cell.We have shown that hydrogen peroxide-induced oxidative stress was causing ∼twofold decrease in the number of lymphocytes secreting the TH1 cytokines IFN-gamma and IL-2, as well as chemokine IL-8 and cytokine TNF alpha.
6820 21057930 However, the number of cells secreting TH2 cytokines IL-4 and IL-5 in hydrogen peroxide-treated group did not change.
6821 21057930 We adopted ELISpot assay for studying oxidative stress in human peripheral blood lymphocytes by analyzing the acute effect of hydrogen peroxide treatment on the frequency of cells secreting IFN-gamma, IL-2, IL-4, IL-5, IL-8, and TNF-alpha.

6825 21076061 Immunologically, SLIT resulted in increased IL-10 production, programmed cell death ligand 1 expression, and concentration of allergen-specific IgG4, as well as in the reduction of CD80 and CD86 expression and IL-4 production.
6826 21105162 Compared with OVA-NPs-treated BMDCs, stimulation with OVA-NPs/protamine led to significantly upregulation of CD80, CD86, and CD83, increased secretion of IL-12p70, and decreased production of IL-4 by BMDCs.
6827 21106776 The serum levels of interleukin-2 (IL-2), gamma interferon (IFN-γ), tumor necrosis factor alpha (TNF-α), IL-4, IL-6, and IL-10 of pneumonic plague patients were determined by enzyme-linked immunosorbent assay.
6828 21106780 The results showed that mice immunized with pVAX-ROP16 developed a high level of specific antibody responses against T. gondii ROP16 expressed in Escherichia coli, a strong lymphoproliferative response, and significant levels of gamma interferon (IFN-γ), interleukin-2 (IL-2), IL-4, and IL-10 production compared with results for other mice immunized with either empty plasmid or phosphate-buffered saline, respectively.
6829 21115722 Nasal immunization with a fusion protein consisting of the hemagglutinin A antigenic region and the maltose-binding protein elicits CD11c(+) CD8(+) dendritic cells for induced long-term protective immunity.
6830 21115722 Analysis of cytokine responses showed that nasal administration of 25k-hagA-MBP induced antigen-specific CD4(+) T cells producing interleukin 4 (IL-4) and IL-5, but not gamma interferon (IFN-γ), in the spleen and cervical lymph nodes (CLNs).
6831 21115722 Furthermore, increased numbers of CD11c(+) CD8α(+), but not CD11c(+) CD11b(+) or CD11c(+) B220(+), dendritic cells with upregulated expression of CD80, CD86, CD40, and major histocompatibility complex class II (MHC II) molecules were noted in the spleen, CLNs, and nasopharynx-associated lymphoreticular tissues (NALT).
6832 21167782 Previous studies suggested an important role for IL-4 in susceptibility to pulmonary tuberculosis; however, the role of IL-4 has not been studied in the guinea pig, a highly relevant model for this disease.
6833 21185849 The results showed that the nanoparticles containing DNA vaccine pRSC-gD-IL-21 induced mice to generate higher levels of specific neutralizing antibody, sIgA in tears, and IFN-γ, IL-4 in serum, and to enhance the cytotoxicities of NK cells and splenocytes as well as splenocyte proliferative response to glycoprotein D compared with those of the control mice.
6834 21236236 Compared to the mice unvaccinated or vaccinated with empty plasmid, CD11c(+) cells at the dLN from naïve B6 mice expressed prominent IL-12 mRNA after the T.g.HSP70 gene vaccine.
6835 21236236 Also, CD4(+) cells at the dLN from the mice expressed prominent interferon-γ, but not IL-4 or IL-17, mRNA at a maximum level at day 5 following vaccination.
6836 21236236 This T.g.HSP70 gene vaccine-induced DC activation and Th1 polarization were also observed in TRIF-deficient mice, but not MyD88-deficient mice with B6 background indicating the involvement of TLR4/MyD88 signal transduction cascade in the vaccine effects with T.g.HSP70 gene.
6837 21236236 The T.g.HSP70 gene vaccine (twice at a 2-week interval) has been shown to limit T. gondii loads in the mesenteric LN of WT, TLR2-deficient and TRIF-deficient mice, but neither TLR4-deficient nor MyD88-deficient mice, at an acute phase of toxoplasmosis.
6838 21236236 The T.g.HSP70 gene vaccine also limited cyst number in the brains of WT, TLR2-deficient and TRIF-deficient mice, but not TLR4-deficient mice at a chronic phase of toxoplasmosis.
6839 21244466 In this study, the secretion of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-8 and IL-1β; Th1 cytokines interferon-gamma (IFN-γ), IL-2 and tumor necrosis factor-beta (TNF-β); and Th2 cytokines IL-4, IL-5 and IL-10 by the peripheral blood mononuclear cells (PBMCs) of pulmonary tuberculosis patients was studied.
6840 21244466 PBMCs from the majority of patients (53-100%) spontaneously secreted detectable concentrations of all cytokines tested, except for IL2 (29%) and IL-10 (41%).
6841 21245658 The cytokine (IL-4, IL-6, IL-10, IL-12 and IL-23) profiles of DCs induced by individual TLR agonists have been evaluated.
6842 21245658 Using various mitogen-activated protein kinase (MAPK) inhibitors (c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK) and p38 MAPK) we have demonstrated the importance of p38 MAPK and ERK signaling pathways in IL-12p70 and IL-12p40 production in DCs induced by TLR stimulation, whereas the JNK pathway appeared to have a negative regulatory role on cytokine production in DCs stimulated with certain TLR agonists.
6843 21252390 Additionally, the lungs, thymus, and lymph nodes of IL-4/Luc/CNS-1 Tg mice evidenced high luciferase activity in response to allergens such as phthalic anhydride (PA), trimellitic anhydride, ovalbumin, gelatin, Dermatophagoides pteronyssinus extracts, and Japanese cedar pollen, whereas key allergy-related indicators including ear thickness, Immunoglobulin E concentration, and the infiltration of inflammatory leukocytes in response to PA were unaltered in the Tg mice relative to the non-Tg mice.
6844 21268002 MOG-pσ1's protective capacity was abrogated in IL-10(-/-) mice, but restored when adoptively transferred with MOG-pσ1-induced Treg.
6845 21268002 MOG-pσ1-treated mice showed elevated IL-4, IL-10, and IL-28 production by CD4(+) T cells, unlike rMOG treated or control mice that produced elevated IFN-γ or IL-17, respectively.
6846 21336991 The molecular weight (23 kDa) and immunogenicity of p23 gene expressed by L. casei Zhang were similar to that of the native P23 protein.
6847 21336991 Furthermore, the expression of cytokines such as IL-4, IL-6, and IFN-γ in splenocytes of mice was detected by real-time PCR after oral immunization.
6848 21340352 Additionally, we studied the effects triggered by antigen-antibodies binding and the levels of key cytokines involved in the humoral response, such as IL-4, IL-5 and IL-6.
6849 21346053 Vaccination with a high dose of OVA-CTLA-4-pcDNA₃.₁ significantly decreased interleukin-4 (IL-4) and IL-5 levels and eosinophil counts and prevented OVA-induced reduction of the gamma interferon level in the bronchoalveolar lavage fluid.
6850 21346228 Typical Th2 cytokines such as IL-10 or IL-4 were undetectable in 2.5mi(+) T cells, arguing against a mechanism of immune deviation.
6851 21354479 Although the elevation of IL-12p40 and IFN-γ was marginal (P≥0.354) in the coated group, interleukin-4 levels were significantly higher (P≥0.013) in the coated group than in the naked or control group, suggesting a predominant Th2-type CD4(+) T cell response.
6852 21408149 To obtain data on Th1 or Th2 dominance of the immune response in adolescents receiving an aP booster immunization after a wcP or aP primary immunization, we analyzed the concentration of Th1 (IL-2, TNF-α, INF-γ) and Th2 (IL-4, IL-5, IL-10) cytokines in supernatants of lymphocyte cultures specifically stimulated with pertussis antigens.
6853 21408149 The vaccination also induces an increase in peripheral CD8(+)CD69(+) activated pertussis-specific memory T cells four weeks after vaccination.
6854 21412284 We have found that coinfection of HSV-IL-2-infected mice with recombinant viruses expressing IL-12p35, IL-12p40 or IL-12p35+IL-12p40 did not block the CNS demyelination, and that coinfection with a recombinant virus expressing interferon (IFN)-γ exacerbated it.
6855 21412284 In contrast, coinfection with a recombinant virus expressing IL-4 reduced demyelination, whereas coinfection of HSV-IL-2-infected mice with a recombinant HSV-1 expressing the IL-12 heterodimer (HSV-IL-12p70) blocked the CNS demyelination in a dose-dependent manner.
6856 21412284 Injection of mice with IL-12p35 DNA, IL-12p40 DNA, IL-12p35+IL-12p40 DNA or IL-23 DNA did not have any effect on HSV-IL-2-induced demyelination, whereas injection of IL-27 DNA increased the severity of the CNS demyelination in the HSV-IL-2-infected mice.
6857 21412284 This study demonstrates for the first time that IL-12p70 can block HSV-IL-2-induced CNS demyelination and that IL-35 can also reduce this demyelination, whereas IFN-γ and IL-27 exacerbated the demyelination in the CNS of the HSV-IL-2-infected mice.
6858 21443963 Supernatants from in vitro stimulated PBMC were tested for cytokines associated with a T(H)1 or T(H)2 T-cell response (IL-2, TNF-α, IFN-γ, IL-4, IL-10, IL-5) and only IFN-γ was associated with protection against fever and/or viremia.
6859 21444117 To address this, CD8(+) T cells from normal OT-I mice or OT-I mice deficient in IFNγ (IFNγ(-/-)) or the IFNγ receptor (IFNγR(-/-)) were activated in vitro in the presence of IFNγ or IL-4 to generate a series of effector populations (Tc1 and Tc2-like respectively) that secreted different levels of IFNγ and expressed different levels of HSV-specific cytolytic function.
6860 21444117 Compared with Tc1 cells, Tc2-like cells produced the type 2 cytokines IL-4 and IL-5, exhibited decreased IFNγ secretion, diminished proliferation in vitro, and decreased antigen-specific cytolysis in vivo.
6861 21444117 To address this, CD8(+) T cells from normal OT-I mice or OT-I mice deficient in IFNγ (IFNγ(-/-)) or the IFNγ receptor (IFNγR(-/-)) were activated in vitro in the presence of IFNγ or IL-4 to generate a series of effector populations (Tc1 and Tc2-like respectively) that secreted different levels of IFNγ and expressed different levels of HSV-specific cytolytic function.
6862 21444117 Compared with Tc1 cells, Tc2-like cells produced the type 2 cytokines IL-4 and IL-5, exhibited decreased IFNγ secretion, diminished proliferation in vitro, and decreased antigen-specific cytolysis in vivo.
6863 21448311 Similar levels of IL-2, IFN-γ, IL-4, and IL-10 cytokines were detected in serum of vaccinated compared with non vaccinated subjects (p > 0.05), as well as between vaccinated adults compared with vaccinated children and non vaccinated subjects (p > 0.05).
6864 21450979 Splenocytes from mice who had received OMPC with the pneumococcal conjugate vaccine produced significantly more interleukin-2 (IL-2), IL-4, IL-6, IL-10, tumor necrosis factor alpha (TNF-α), and gamma interferon (IFN-γ) than splenocytes from mice who received phosphate-buffered saline (PBS) plus the conjugate vaccine.
6865 21463625 DCs were generated from peripheral blood monocytes with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor (GM-CSF).
6866 21463625 Compared to DCs treated with E7 in a 2-D culture model, the expression of co-stimulatory molecules CD80 and CD40 were significantly increased in the 3-D model (p<0.05), and a remarkable increase of IL-12 p70 was observed.
6867 21469087 CD38 identifies a hypo-proliferative IL-13-secreting CD4+ T-cell subset that does not fit into existing naive and memory phenotype paradigms.
6868 21469087 Herein, we show that CD38 expression identifies a hypo-proliferative CD4(+) T-cell subset that, following TCR stimulation, retains expression of naive cell surface markers including CD45RA, CD62L and CCR7.
6869 21469087 Hypo-proliferation was mediated by reduced CD25 up-regulation upon TCR stimulation compared to CD4(+) CD38(-) cells and lack of responsiveness to exogenous IL-2.
6870 21469087 Instead, CD4(+) CD38(+) T cells expressed CD127, and hypo-proliferation was reversed by addition of IL-7, further associated with increased STAT5 phosphorylation.
6871 21469087 Activated CD4(+) CD38(+) cells had a bias towards IL-13 secretion, but not other Th2 cytokines such as IL-4 or IL-5.
6872 21469087 In comparison, the CD4(+) CD38(-) cells had a clear bias towards secretion of Th1-associated cytokines IFN-γ and TNF.
6873 21469087 The existence of such CD4(+) CD38(+) T cells may play an important role in pathologies such as asthma, which are associated with IL-13, but not IL-4 and IL-5.
6874 21469087 Coupled with responsiveness to IL-7 but not IL-2, and the involvement of CD38 ligation, our results highlight a unique T-cell subpopulation that does not fit into existing naive and memory cell paradigms.

6883 21469112 In this study, we show that, in mice, immunization with soluble, recombinant FliC protein flagellin (sFliC) induces Th2 responses as evidenced by Ag-specific GATA-3, IL-4 mRNA, and protein induction in CD62L(lo) CD4(+) T cells without associated IFN-γ production.
6884 21469112 Salmonella infection in sFliC-immunized mice resulted in augmented Th1 responses, with greater bacterial clearance and increased numbers of IFN-γ-producing CD4(+) T cells, despite the early induction of Th2 features to sFliC.
6885 21469117 Here, we show that IL-4 and IL-13 production is NF-κB1-dependent in mouse OVA-specific CD4(+) (OTII) T cells responding to alum-precipitated OVA (alumOVA) immunization.
6886 21469117 More surprisingly, we found that NF-κB1 deficiency in OTII cells also selectively impairs their CXCR5 induction by alumOVA without affecting upregulation of BCL6, IL-21, OX40 and CXCR4 mRNA and PD-1 protein.
6887 21469117 The selective effects of NF-κB1-deficiency on Th2 and follicular helper T cell induction do not appear to be due to altered expression of the Th2-associated transcription factors - GATA-3, c-Maf and Ikaros.
6888 21469117 Altogether, these results suggest that NF-κB1 regulates the expression of CXCR5 on CD4(+) T cells primed in vivo, and thus selectively controls the T-cell-dependent germinal center component of B-cell response to alumOVA.
6889 21482422 The result showed that three adjuvants could enhance antibody titer, T lymphocyte proliferation, IL-2 and IL-4 secretion of splenic lymphocyte.
6890 21482422 The result showed that propolis and oilemulsion could enhance the antibody titer, IL-2 and IL-4 content in serum and decrease the PPV content in blood and viscera.

6893 21536790 NWs and BALF as well as plasma of mice given nasal rPspA plus pFL contained increased levels of rPspA-specific secretory IgA and IgG Ab responses that were correlated with elevated numbers of CD8(+) and CD11b(+) DCs and interleukin 2 (IL-2)- and IL-4-producing CD4(+) T cells in the nasal mucosa-associated lymphoid tissues (NALT) and cervical lymph nodes (CLNs).
6894 21565244 SL immunization promoted a mixed Th1/Th2 response, based on cytokine analysis (IL-2, IL-4, IL-10 and INFγ).
6895 21593356 The levels of DNP-KLH-specific IgG in the sera as well as keyhole limpet hemocyanin-specific IFNγ and IL-4 production by splenic CD4(+) cells were similar in the Lyc and Con pups.
6896 21596404 A significant increase was observed in IL-2, IL-4 and IFN-γ levels in the culture supernatants of splenocytes isolated from immunized mice.
6897 21697351 Infection with either virus resulted in elevated expression of several pro- and anti-inflammatory cytokines [interleukin (IL)-1β, IL-4, IL-6, IL-8, IL-10 and tumour necrosis factor-α) with a corresponding increase in transcription.
6898 21717080 The protective effect, as a result of vaccination, correlated with an increase in the levels of IL-10 and IL-4 cytokines as well as a skewing to Th2-dependent isotype antibodies in serum.
6899 21722668 In the present work we demonstrated that recombinant human calcineurin subunit B (rhCnB) stimulated the expression of the surface molecules CD83, CD80, CD86, CD40, and HLA-DR.
6900 21722668 It also promoted secretion of inflammatory cytokines IL-6, TNF-α, and IL-1β by human PBMC-derived dendritic cells.
6901 21722668 Transcript levels of cytokines such as IL-4, IL-10, and IFN-γ in the splenocytes were also upregulated when in vitro stimulated with pneumolysin.
6902 21742003 In this study, a novel SSI fusion protein that contains the critical toxin-antigens Stx2B and Stx1B, and the critical adhesion-antigen fragment Int281 was constructed.
6903 21742003 The dominant increase in IgG1 and the high level of Th2-typical cytokine (IL-4 and IL-10) expression showed that SSI significantly induced Th2-mediated humoral immune response.
6904 21742003 In the mouse model, the SSI fusion protein not only elicited neutralizing antibodies against both Stx1 and Stx2 toxins, but also induced a high level of anti-adhesion antibodies.
6905 21760754 Cytokine responses of antigen-responding cells in the spleen secreted predominantly IFN-γ and IL-5 in response to BmVAL-1, and IL-4, and IL-5 in response to BmALT-2.
6906 21782860 To better understand the potential role of cytokines in the pathogenesis of EIAV infection and resulting immune response, we used branched DNA technology to compare the mRNA expression levels of 12 cytokines and chemokines, including IL-1α, IL-1β, IL-4, IL-10, TNF-α, IFN-γ, IP-10, IL-8, MIP-1α, MIP-1β, MCP-1, and MCP-2, in equine monocyte-derived macrophages (eMDMs) infected with the EIAV(DLV121) vaccine strain or the parental EIAV(DLV34) pathogenic strain.
6907 21782860 In the early stage of infection with EIAV(DLV34) (0-24h), the expression of the pro-inflammatory cytokines TNF-α and IL-1β were significantly up-regulated, while with EIAV(DLV121), expression of the anti-inflammatory cytokine IL-4 was markedly up-regulated.
6908 21782860 During the first 4 days after infection, the expression level of IL-4 in cells infected with the pathogenic strain were significantly higher than that in cells infected with the vaccine strain, but the expression of IL-1α and IL-1β induced by the vaccine strain was significantly higher than that observed with the pathogenic strain.
6909 21782860 To better understand the potential role of cytokines in the pathogenesis of EIAV infection and resulting immune response, we used branched DNA technology to compare the mRNA expression levels of 12 cytokines and chemokines, including IL-1α, IL-1β, IL-4, IL-10, TNF-α, IFN-γ, IP-10, IL-8, MIP-1α, MIP-1β, MCP-1, and MCP-2, in equine monocyte-derived macrophages (eMDMs) infected with the EIAV(DLV121) vaccine strain or the parental EIAV(DLV34) pathogenic strain.
6910 21782860 In the early stage of infection with EIAV(DLV34) (0-24h), the expression of the pro-inflammatory cytokines TNF-α and IL-1β were significantly up-regulated, while with EIAV(DLV121), expression of the anti-inflammatory cytokine IL-4 was markedly up-regulated.
6911 21782860 During the first 4 days after infection, the expression level of IL-4 in cells infected with the pathogenic strain were significantly higher than that in cells infected with the vaccine strain, but the expression of IL-1α and IL-1β induced by the vaccine strain was significantly higher than that observed with the pathogenic strain.
6912 21782860 To better understand the potential role of cytokines in the pathogenesis of EIAV infection and resulting immune response, we used branched DNA technology to compare the mRNA expression levels of 12 cytokines and chemokines, including IL-1α, IL-1β, IL-4, IL-10, TNF-α, IFN-γ, IP-10, IL-8, MIP-1α, MIP-1β, MCP-1, and MCP-2, in equine monocyte-derived macrophages (eMDMs) infected with the EIAV(DLV121) vaccine strain or the parental EIAV(DLV34) pathogenic strain.
6913 21782860 In the early stage of infection with EIAV(DLV34) (0-24h), the expression of the pro-inflammatory cytokines TNF-α and IL-1β were significantly up-regulated, while with EIAV(DLV121), expression of the anti-inflammatory cytokine IL-4 was markedly up-regulated.
6914 21782860 During the first 4 days after infection, the expression level of IL-4 in cells infected with the pathogenic strain were significantly higher than that in cells infected with the vaccine strain, but the expression of IL-1α and IL-1β induced by the vaccine strain was significantly higher than that observed with the pathogenic strain.
6915 21795462 The results suggested that BP5 markedly elevated serum hemagglutination inhibition (HI) titers and antigen-specific antihemagglutinin (anti-HA) antibody (IgG) levels, induced both Th1 (interleukin 2 [IL-2] and gamma interferon [IFN-γ])- and Th2 (IL-4)-type cytokines, promoted the proliferation of peripheral blood lymphocytes, and increased populations of CD3(+) T cells and their subsets CD4(+) (CD3(+) CD4(+)) T cells and CD8(+) (CD3(+) CD8(+)) T cells.
6916 21820185 The basic objective of this study was to enumerate whether co-administration of interferon-γ (IFN-γ) and/or interleukin-4 (IL-4) gene along with a bivalent Newcastle disease (ND) DNA vaccine construct could modulate the immune response to the DNA vaccine in chickens. pVIVO2 vector carrying Haemaglutinin-Neuraminidase (HN) and Fusion (F) genes of Newcastle disease virus (NDV) at its two cloning sites was used as a DNA vaccine.
6917 21822116 Serum cytokines [interleukin-2 (IL-2), IL-4, IL-6, interferon gamma, and tumor necrosis factor alpha] were assayed using standardized methodology.
6918 21856352 When the plasmid contained both motifs, transfected murine macrophage-like RAW264.7 cells showed markedly increased levels of mRNA for immune molecules of Th1 (IFN-α, IL-12) and Th17 (IL-17, IL-23 and IL-6) responses and for T cell co-stimulatory molecules (CD80 and CD86) but not for a Th2 response (IL-4 and IL-10).
6919 21879287 In this paper we have studied memory/naïve B cells in the elderly, evaluating surface immunoglobulin expression, production of the pro- and anti-inflammatory cytokines, tumor necrosis factor (TNF)-α and interleukin (IL)-10, and presence of somatic hypermutation, focusing on the IgG(+)IgD(-)CD27(-) double negative (DN) B cells that are expanded in the elderly.
6920 21879287 Our results show that naïve B cells from young donors need a sufficiently strong stimulus to be activated "in vitro", while naïve B cells from old subjects are able to produce IL-10 and TNF-α when stimulated "physiologically" (α-CD40/IL-4), suggesting that these cells might play a role in the control of the immuno-inflammatory environment in the elderly.
6921 21880854 Dexamethasone reduced IFNG transcription by day 12 and IL-8 and IL-18 by days 7 to 9 and increased IL-4 on day 7.
6922 21880854 The ratio of IL-10 to IFNG was increased by dexamethasone on day 9.
6923 21882046 LsPass1-challenged mice showed no protection, however, a strong degree of protection associated to smaller lesions and high expression of IFN-γ and TNF-α by CD4(+) T, CD8(+) T and double negative CD4CD8 cells was achieved in LsPass3-challenged mice.
6924 21882046 Furthermore, LsPass2-challenged mice showed an intermediated degree of protection associated to high levels of IFN-γ, IL-4 and IL-10 mRNA.
6925 21882046 In spite of increased expression of IFN-γ and TNF-α, high amounts of IL-4 and IL-10 mRNA were also detected in LsPass3-challenged mice indicating a possible contribution of these cytokines for the persistence of a residual number of parasites that may be important in inducing long-lasting immunity.
6926 21882046 LsPass1-challenged mice showed no protection, however, a strong degree of protection associated to smaller lesions and high expression of IFN-γ and TNF-α by CD4(+) T, CD8(+) T and double negative CD4CD8 cells was achieved in LsPass3-challenged mice.

6928 21882046 In spite of increased expression of IFN-γ and TNF-α, high amounts of IL-4 and IL-10 mRNA were also detected in LsPass3-challenged mice indicating a possible contribution of these cytokines for the persistence of a residual number of parasites that may be important in inducing long-lasting immunity.
6929 21906881 The production levels of IFN-γ, IL-2, IL-4, and IL-10, as well as the percentage of CD4(+) cells in mice vaccinated with pVAX-ROM1 were significantly increased respectively, compared to controls receiving either pVAX1 alone or PBS.
6930 21914064 The DNA of HBV S gene and the cDNA of the extracellular domain of human CD40 ligand were linked by cloning.
6931 21914064 Peripheral blood mononuclear cells (PBMC) from healthy adults were incubated and induced into dendritic cells (DC) in presence of granulocyte/macrophage colony-stimulating factor (GM-CSF) and interleukin-4(IL-4).
6932 21914064 We find that, compared with control groups, modification of DCs with HBV S-ecdCD40L fusion gene resulted in the activation of DCs with upregulated expression of immunologically important cell surface molecules (CD80, CD86 and HLA-DR) and proinflammatory cytokines (IL-12).
6933 21945176 Protective immunity in mice was associated with high titers of rP22-specific IgG antibodies; elevated production of IFN-γ, TNF-α and IL-10; and a reduced level of IL-4.
6934 21945255 We found elevated levels of the Th1 associated cytokine INF-γ, the Th2-cytokine IL-4, the proinflammatory IL-6 and IL-17A, and the regulatory cytokine IL-10.
6935 21945396 Recently it has been shown that IgG antibody secreting cells (ASCs) can be generated by in vitro maturation of blood cells with Interleukin- (IL-)15 and CpG DNA or other stimulation cocktails, while IgE-ASCs develop upon cultivation with anti-CD40 and IL-4.
6936 21956503 We worked out a protocol to study oxidative stress in human peripheral blood lymphocytes by determining their potency to secrete IFN-gamma, IL-2, IL-4, IL-5, IL-8, and TNF-alpha in response to acute treatment with hydrogen peroxide.
6937 21956503 We show that hydrogen peroxide-induced oxidative stress can cause a ∼twofold decrease in the number of lymphocytes secreting the TH1 cytokines IFN-gamma and IL-2, as well as chemokines IL-8 and TNF-alpha.
6938 21956503 However, the number of cells secreting TH2 cytokines IL-4 and IL-5 in hydrogen -peroxide-treated group did not change.
6939 21956503 We worked out a protocol to study oxidative stress in human peripheral blood lymphocytes by determining their potency to secrete IFN-gamma, IL-2, IL-4, IL-5, IL-8, and TNF-alpha in response to acute treatment with hydrogen peroxide.
6940 21956503 We show that hydrogen peroxide-induced oxidative stress can cause a ∼twofold decrease in the number of lymphocytes secreting the TH1 cytokines IFN-gamma and IL-2, as well as chemokines IL-8 and TNF-alpha.
6941 21956503 However, the number of cells secreting TH2 cytokines IL-4 and IL-5 in hydrogen -peroxide-treated group did not change.
6942 21958369 We measured multiple VACV-specific immune responses: neutralizing antibody titer, the level of 12 secreted cytokines in peripheral blood mononuclear cell (PBMC) cultures (IL-1β, IL-2, IL-4, IL-6, IL-10, IL-12p40, IL-12p70, TNF-α, IFN-γ, IFN-α, IFN-β, and IL-18), and the number of IFN-γ- and CD8(+) IFN-γ-secreting cells.
6943 21958369 We also detected strong correlations between the proinflammatory cytokines IL-1β, TNF-α, IL-6, and IL-12p40 (p<0.0001).
6944 21972614 Levels of IFN-gamma and IL-4 in the splenocyte culture supernatants were determined by ELISA.
6945 22052597 A total of 10 single nucleotide polymorphisms distributed in 6 genes (TNFRSF1A, IL12A, IL12B, IFNG, IL4, and IL10) were genotyped in 214 high-responders [hepatitis B surface antibody (anti-HBs) ≥1,000 mIU/ml] and 107 low-responders (anti-HBs: 10-99 mIU/ml).
6946 22052597 In addition, a significant gene-gene interaction was found: the frequency of the combined genotypes IL12A rs2243115 TT and IL12B rs17860508 CTCTAA/CTCTAA was significantly higher in the low-response group than in the high-response group (P = 0.008, odds ratio = 2.19, 95% confidence interval = 1.23-3.93).
6947 22052597 These findings suggest that polymorphisms in the IL12A and IL12B genes might play an important role jointly in determining the response to hepatitis B vaccination.
6948 22063002 Immunization with particulate formulations led to significantly increased IL-2, IL-4, IL-10 and IFN-γ production by splenic CD4+ T-cells compared to control animals.
6949 22066023 Mucosae-associated epithelial chemokine (MEC or CCL28) binds to CCR3 and CCR10 and recruits IgA-secreting plasma cells (IgA-ASCs) in the mucosal lamina propria.
6950 22066023 Mice receiving either HIV-1(IIIB) VLPs alone, CCL28 alone, or the irrelevant CCL19 chemokine were used as controls.
6951 22066023 Results showed a significantly increased CCR3 and CCR10 expression on CD19(+) splenocytes of HIV-1(IIIB) VPL-CCL28-treated mice.
6952 22066023 HIV-1 Env-specific IFN-γ, IL-4 and IL-5 production, total IgA, anti-Env IgA as well as gastro-intestinal mucosal IgA-secreting plasma cells were also significantly augmented in these mice.
6953 22067741 Yeast-surface expressed BVDV E2 protein induces a Th1/Th2 response in naïve T cells.
6954 22067741 S. cerevisiae activates the innate immune system by engaging pattern recognition receptors such as toll like receptor 2 (TLR2) and dectin-1.
6955 22067741 Additionally, bovine macrophages primed with S. cerevisiae expressing viral envelope proteins had a greater capacity for stimulating proliferation of CD4+ T-cells from BVDV-free animals compared to macrophages primed with envelope protein alone or S. cerevisiae without envelope protein expression.
6956 22067741 Additionally, heat-inactivation of recombinant S. cerevisiae induced less INFγ and IL-4 but equal amounts of IL-10 compared to live yeast T-cell cultures.
6957 22072720 Increased amounts of antigen-specific gamma interferon, interleukin-17A (IL-17A), IL-6, and tumor necrosis factor alpha were produced from splenocytes postvaccination, but no or minimal IL-4, IL-5, or IL-10 was produced, indicating Th1- and Th17-biased T cell responses.
6958 22079980 The soluble L. donovani Ag stimulated PBMCs of cured/exposed and Leishmania patients to produce a mixed Thl/Th2-type cytokine profile, whereas rLelF-2 stimulated the production of IFN-γ, IL-12, and TNF-α but not IL-4 or IL-10.
6959 22079980 Further, rLelF-2 downregulated LPS-induced IL-10 as well as soluble L. donovani Ag-induced IL-4 production by Leishmania patient PBMCs.
6960 22079980 The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFN-γ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.
6961 22079980 The soluble L. donovani Ag stimulated PBMCs of cured/exposed and Leishmania patients to produce a mixed Thl/Th2-type cytokine profile, whereas rLelF-2 stimulated the production of IFN-γ, IL-12, and TNF-α but not IL-4 or IL-10.
6962 22079980 Further, rLelF-2 downregulated LPS-induced IL-10 as well as soluble L. donovani Ag-induced IL-4 production by Leishmania patient PBMCs.
6963 22079980 The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFN-γ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.
6964 22079980 The soluble L. donovani Ag stimulated PBMCs of cured/exposed and Leishmania patients to produce a mixed Thl/Th2-type cytokine profile, whereas rLelF-2 stimulated the production of IFN-γ, IL-12, and TNF-α but not IL-4 or IL-10.
6965 22079980 Further, rLelF-2 downregulated LPS-induced IL-10 as well as soluble L. donovani Ag-induced IL-4 production by Leishmania patient PBMCs.
6966 22079980 The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFN-γ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.
6967 22087247 Results showed that SIS affected cytokine and chemokines microenvironments such as up-regulation of IL-4 and CD30-ligand and activation of chemotactic factors LIX and KC (neutrophil chemotactic factors), MCP-1 (monocytes chemotactic factors), MIP 1-α (macrophage chemotactic factor) and lymphotactin, as well as, growth factors like M-CSF.
6968 22087247 However, in contrast to alum, SIS had no effects on pro-inflammatory cytokines (IL-6, IL-1β, TNF-α) or NLRP3, but it appeared to promote both Th1 and Th2 responses under different conditions.
6969 22089247 The protective response mediated by the injection of primed DCs was characterized mainly by an increased production of gamma interferon (IFN-γ) and interleukin 12 (IL-12) and a reduction in IL-10 and IL-4 compared to those of infected mice that received saline or unprimed DCs.
6970 22114877 Evaluation of the immune response induced by DNA vaccines expressing MIF and MCD-1 genes of Trichinella spiralis in BALB/c mice.
6971 22114877 Plasmids expressing macrophage migration inhibitory factor (MIF) of Trichinella spiralis (TsMIF), multi-cystatin-like domain protein (MCD-1) of T. spiralis (TsMCD-1), or co-expressing TsMIF and TsMCD-1 were constructed with a pVAX1 vector.
6972 22114877 Specific antibody levels (IgG, IgG1, IgG2a, IgG2b, IgM, IgA, IgE) against the recombinant protein TsMIF-TsMCD-1, serum cytokines (interferon (IFN)-γ, interleukin (IL)-4, IL-5, transforming growth factor (TGF)-β1 and IL-17) and CD4+/CD8+ T cells were monitored.
6973 22114877 Vaccination with pVAX1-Tsmif induced moderate serum IFN-γ and increases of CD4+ and CD8+ T cells, but no specific immunoglobulin antibody response.
6974 22114877 Importantly, co-expression of TsMIF and TsMCD-1 in DNA immunization produced more serum IFN-γ and markedly enhanced CD4+ and CD8+ T cells than the single DNA vaccine of the two genes.
6975 22119401 The cytokine interleukin-1 beta (IL-1β) is a potent inflammatory mediator in response to infection, and can be used as an immunological adjuvant.
6976 22119401 The expression of various cytokines from peripheral blood mononuclear cells measured by fluorescent microsphere immunoassay showed that IL-1β, IL-4 and IFN-γ expression levels were up-regulated in pigs infected with vP129/swIL1β at 7 and 14 days post-infection.
6977 22120532 Co-stimulation with TLR3 and TLR21 ligands synergistically up-regulates Th1-cytokine IFN-γ and regulatory cytokine IL-10 expression in chicken monocytes.
6978 22120532 Chicken TLR3 and TLR21 (avian equivalent to mammalian TLR9) recognize poly I:C (double-stranded RNA) and CpG-ODN (a CpG-motif containing oligodeoxydinucleotide), respectively.
6979 22120532 The objective of the present study was to investigate the effect of the interaction between poly I:C and CpG-ODN on the mRNA expression levels of IFN-α and IFN-β, Th1 cytokines IFN-γ and IL-12, Th2 cytokine IL-4, and regulatory IL-10 in chicken monocytes.
6980 22125550 Determinations of peripheral blood cytokine and chemokine profiles following individual protein immunizations show that interleukin-2 (IL-2) and IL-4 are elicited by the three confirmed candidates, but unexpectedly interferon-γ and tumor necrosis factor-α are not.
6981 22131355 The results showed that both LA4356-pH and DLD17-pH could significantly increase the specific anti-HA(1) IgA antibody level in the mucosa and the anti-HA(1) IgG level in serum, as well as stimulating the splenic lymphocyte proliferative reaction through increased expression of interleukin-4 (IL-4).
6982 22200492 Furthermore, Ad-FL activated DCs induced IFN-γ, IL-2 and IL-4 producing CD4(+) T cells.
6983 22207133 A mixed T(h)-cell response was induced as evident by the enhanced IL-4, IL-10, IFN-γ and TNF-α-specific cytokine-forming cells.
6984 22210400 When antibody titers were measured from immunized animals together with IL-2, IL-4 and IFNγ production from splenocytes in vitro, we found that proteins displayed on λ were superior at eliciting an immune response in comparison to genetic immunization with λ.
6985 22211657 Results of cytokine and ELISpot assays also showed the capability of VLP+OMV immunogen for effective induction of IFN-gamma; and IL4 secreting cells and further suggested the promotion of Th1-oriented response that was evidenced with the increased IFN-γ/IL4 secretion ratio.
6986 22294447 Two weeks after three subcutaneous doses of DNA vaccine, the mice were challenged intranasally with 1 LD50 of A/Puerto Rico/8/34 (H1N1) virus, and PB1- and HA-specific antibodies, survival rate, body weight change, viral mRNA load, infectious virus titer in the lungs, cytokines IL-2, IL-4 and IL-10, and granzyme-B were measured.
6987 22308307 This issue is especially pertinent given recent data showing that memory-like CD8 T cells can be generated in the thymus, in a bystander response to IL-4.
6988 22310204 The results showed that the group immunized with pcDNA-IMP1 developed a high level of specific antibody responses against Escherichia coli expressed recombinant TgIMP1, with high IgG antibody titers, predominance of IgG2a production, a strong lymphoproliferative response, and significant levels of IFN-γ, IL-2, IL-4 and IL-10 production compared with the control groups.
6989 22327491 Adoptive transfer of in vitro isolated lymphocyte subsets revealed that reconstituting mice with IsdB specific CD3+ or CD4+ T-cells conferred antigen specific protection while CD8(+) T-cells, CD19(+) B-cells and plasma cells (CD138(high)B220(int)CD19(lo)) alone were not protective.
6990 22327491 A combination of CD3(+) T-cells plus CD19(+) B-cells conferred protection in CB-17 SCID mice, whereas bovine serum albumin (BSA) immune lymphocytes did not confer protection.
6991 22327491 In vitro assays indicated that isolated IsdB specific splenocytes from immunized mice produced abundant IL-17A, much less IFN-γ and no detectable IL-4.
6992 22327491 IL-23 deficient mice were not protected from a lethal challenge by IsdB vaccination, pointing to a critical role for CD4(+) Th17 in IsdB-mediated vaccination.
6993 22327491 Neutralizing IL-17A, but not IL-22 in vivo significantly increased mortality in IsdB immunized mice; whereas, neutralizing IFN-γ did not alter IsdB-mediated protection.
6994 22342709 BCG vaccination did not significantly modulate the levels of serum IFN-γ and the frequency of splenic PPD-reactive IFN-γ-secreting T cells, but significantly decreased the levels of serum TNF-α and PPD-specific IL-4 responses at 3 weeks post challenge.
6995 22365841 Murine bone marrow-derived DCs were cultured and matured with LPS, IL-4 and IFN-γ (type-1 polarized DCs), and with LPS alone (non-polarized DCs).
6996 22379063 Levels of IgG antibody, gamma interferon (IFN-γ), interleukin 2 (IL-2), IL-12, IL-4, and IL-10 were examined.
6997 22379063 The levels of Toxoplasma-specific IgG, IFN-γ, IL-2, and IL-12 increased significantly, and the numbers of cysts in brains decreased more obviously, in the group immunized with plasmid pIRESneo/MIC6/PLP1 than in the other groups (P < 0.05).
6998 22386518 Vaccination with VLP and α-galactosylceramide activated splenic iNKT cells to produce IFN-γ and IL-4, led to the generation of antigen-specific T cells that protected prophylactically against subcutaneous tumor challenge, and was more effective at generating anti-tumor immune responses than either component individually.
6999 22427637 Bcl6 and Maf cooperate to instruct human follicular helper CD4 T cell differentiation.
7000 22427637 The introduction of Bcl6 expression in primary human CD4 T cells resulted in the regulation of a core set of migration genes that enable trafficking to germinal centers: CXCR4, CXCR5, CCR7, and EBI2.
7001 22427637 Bcl6 expression also induced a module of protein expression critical for T-B interactions, including SAP, CD40L, PD-1, ICOS, and CXCL13.
7002 22427637 This constitutes direct evidence for Bcl6 control of most of these functions and includes three genes known to be loci of severe human genetic immunodeficiencies (CD40L, SH2D1A, and ICOS).
7003 22427637 Introduction of Bcl6 did not alter the expression of IL-21 or IL-4, the primary cytokines of human Tfh cells.
7004 22427637 Coexpression of Bcl6 and Maf revealed that Bcl6 and Maf cooperate in the induction of CXCR4, PD-1, and ICOS.
7005 22427637 Altogether, these findings reveal that Bcl6 and Maf collaborate to orchestrate a suite of genes that define core characteristics of human Tfh cell biology.
7006 22428079 The large extracellular loop of the Schistosoma mansoni tetraspanin, Sm-TSP-2, when fused to a thioredoxin partner and formulated with Freund's adjuvants, has been shown to be an efficacious vaccine against murine schistosomiasis.
7007 22428079 The enhanced protection obtained with the chimeric fusion protein was associated with increased production of anti-Sm-TSP-2 antibodies and IL-4, IL-10 and IFN-γ from spleen cells of vaccinated animals.
7008 22441393 Short-term HAART resulted in a moderate increase in the expression of PD-1 on both CD4(+) and CD8(+) T cells; yet, there was still a significant reduction in viral load and recovery of CD4(+) T cells.
7009 22441393 There were no significant changes in the proinflammatory cytokine interleukin-2 (IL-2) or Th-2 cytokines (IL-4, IL-5, and IL-10) in the corresponding samples.
7010 22465737 The results showed that the mice immunized with pVAX-Enol developed a high level of specific antibody responses against A. suum, a strong lymphoproliferative response, and significant levels of IFN-γ, IL-2, IL-4 and IL-10 production, compared with the other groups immunized with empty plasmid or blank controls, respectively.
7011 22507968 Furthermore, CD8(+) splenocytes for IFN-γ positive cell assay and the release profile of Th1/Th2 type cytokines (IFN-γ, IL-2, IL-10, and IL-4) showed that hydrogel/Ad-GPZ generated an overwhelmingly enhanced Th1 biased cellular immune response.
7012 22511971 Peripheral blood mononuclear cells (PBMC) stimulated in vitro with inactivated CpHV-1 produced high levels of soluble IFN-gamma and exhibited high frequencies of IFN-gamma producing cells while soluble IL-4 was undetectable.
7013 22518008 However, mice that were vaccinated twice with the DNA vaccine and boosted with the IPV could mount a sufficient neutralizing antibody response against live PHE-CoV, with little variation in IgG1 and IgG2a levels, and showed high levels of IL-2 and IL-4.
7014 22521604 Analysis of cytokine production by stimulated splenocytes demonstrated that prenatal Cd exposure decreased IL-2 and IL-4 production by cells from female offspring at 2weeks of age.
7015 22521604 CD4(+)FoxP3(+)CD25(+) (nTreg) cell percentages were increased in the spleen and thymus in all Cd-exposed offspring except in the female spleen where a decrease was seen.
7016 22521604 CD8(+)CD223(+) T cells were markedly decreased in the spleens in all offspring at 7weeks of age.
7017 22552442 We found that pcDNA3.1-T-bet-Ag85B not only induced evidently higher IgG2a antibody responses, but also increased the production of interferon-γ (IFN-γ) and interleukin (IL)-2 with the concomitant repression of IL-4 and IL-10 compared with pcDNA3.1-Ag85B alone or the empty vector.
7018 22582289 In both experiments I and II, a 15-μg IL-4-plasmid injection decreased fecal oocyst shedding, decreased the number of CD8(+) cells in the cecal tonsils, and decreased cecal tonsil lymphocyte cell proliferation postcoccidia challenge.
7019 22648753 Blood samples were obtained weekly to determine serum neutralizing (SN) antibody titers to IBRV, BVDV-1, BVDV-2, and PI-3 and cytokine levels for IL-4, IL-6, TNF-α (tumor necrosis factor-α), and IFN-γ (interferon-gamma).
7020 22675156 Concentrations of interleukin 1β (IL-1β), IL-4, IL-6, CXCL8 (IL-8), IL-10, IL-12p70, IL-17, CCL2 (monocyte chemoattractant protein 1), tumor necrosis factor alpha (TNF-α), and gamma interferon (IFN-γ) were measured by multiplex cytokine array.
7021 22675156 When M. tuberculosis-infected macrophages were cocultured with monocyte-depleted peripheral blood mononuclear cells, IFN-γ (P = 0.01), TNF-α (P = 0.04), IL-10 (P < 0.001), and IL-6 (P = 0.03) exhibited similar continua of responses, with uninfected persons producing the lowest levels, followed by extrapulmonary tuberculosis cases, pulmonary tuberculosis controls, and persons with latent M. tuberculosis infection.
7022 22675156 A similar pattern was observed with CXCL8 (P = 0.04), IL-10 (P = 0.02), and CCL2 (P = 0.03) when monocyte-depleted peripheral blood mononuclear cells from the four groups were cultured alone.
7023 22704924 Protection was associated with a pronounced enhancement of parasite-specific IFNγ-producing cells and reduction of cells producing IL-10, whereas IL-4 production was comparable in protected and non-protected mice.
7024 22705080 The cellular immune response levels in the co-inoculation groups were higher than those groups receiving the PPV oil emulsion vaccine alone, with the phenomena of higher level of IFN-γ, a little IL-6 and a trace of IL-4 in serum, and a vigorous T-cell response.
7025 22720235 While T cells loaded with a class I-restricted peptide induced proliferation but not effector differentiation of antigen-specific CD8 T cells, injection of T cells co-pulsed with αGC strongly induced IFNγ and Granzyme B expression in T cells and complete lysis of target cells in vivo.
7026 22720235 Of note, the generation of this cytotoxic T cell response was independent of IL-4, IFNγ, IL-12, IL-21 and costimulation.
7027 22735846 The expression of intracellular cytokines (IL-2, IL-4 and IFNγ) in CD4+- and CD8+-cells was also enhanced following in-vitro stimulation with SE22.
7028 22745375 Expanded Vγ2Vδ2 T cells could evolve into effector cells producing IFN-γ, TNF-α, IL-4, IL-17, or perforin after L. monocytogenes infection, and some effector Vγ2Vδ2 T cells could coproduce IL-17 and IFN-γ, IL-4 and IFN-γ, or TNF-α and perforin.
7029 22798686 Type II NKT cells facilitated production of IL-4, IL-5, IL-10, IL-13, and antibody by LN and splenocyte cultures following Alum/antigen administration in vivo and antigen restimulation in vitro.
7030 22798686 Addition of IL-4 and IL-5 to type II NKT-deficient cultures restored in vitro antibody production.
7031 22798686 Type II NKT cells facilitated production of IL-4, IL-5, IL-10, IL-13, and antibody by LN and splenocyte cultures following Alum/antigen administration in vivo and antigen restimulation in vitro.
7032 22798686 Addition of IL-4 and IL-5 to type II NKT-deficient cultures restored in vitro antibody production.
7033 22802961 CD4(+)CD25(+) regulatory T cells (Tregs) do not only influence self-antigen specific immune responses, but also dampen the protective effect induced by a number of vaccines.
7034 22802961 The impact of CD4(+)CD25(+) Tregs on vaccines against schistosomiasis, a neglected tropical disease that is a major public health concern, however, has not been examined.
7035 22802961 IFN-γ, GM-CSF and IL-4) and an anti-inflammatory cytokine (e.g.
7036 22802961 IL-10), with CD4(+)CD25(-) T cells being one of the major sources of both IFN-γ and IL-10.
7037 22802961 These findings indicate that partial CD25(+) cell depletion fails to enhance the effectiveness of the schistosome vaccine, possibly due to IL-10 production by CD4(+)CD25(-) T cells, or other cell types, after CD25(+) cell depletion during vaccination.
7038 22802978 Dendritic cell-mediated vaccination relies on interleukin-4 receptor signaling to avoid tissue damage after Leishmania major infection of BALB/c mice.
7039 22825591 Several studies provided evidence of innate interferons (IFNs) regulating T(H)2 cytokine production using purified CD4(+) memory cells and T(H)2 polarisation via interleukin-4 (IL-4).
7040 22825591 IFN-γ, IL-5 and IL-13 protein levels were measured by ELISA.
7041 22829882 With regard to cytokines, the SAP led to production of interleukin (IL)-2, IL-6, and IL-4.
7042 22829882 IFA promoted production of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-6, IL-17, IL-4, and IL-10.
7043 22829882 We also observed that MPL induced high production of IL-2, TNF-α, and IFN-γ, in addition to IL-6, IL-17, and IL-10.
7044 22829882 With regard to cytokines, the SAP led to production of interleukin (IL)-2, IL-6, and IL-4.
7045 22829882 IFA promoted production of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-6, IL-17, IL-4, and IL-10.
7046 22829882 We also observed that MPL induced high production of IL-2, TNF-α, and IFN-γ, in addition to IL-6, IL-17, and IL-10.
7047 22846987 Furthermore, the elicited IL-2, IL-4 and γ-IFN levels showed good correlation with the degree of protection.
7048 22855393 The response is contact dependent and major histocompatibility complex class II dependent and primarily involves CD3(+) CD4(+) CD8(-) T cells.
7049 22855393 Although many of these FoxP3(+) T cells are capable of producing the effector cytokines interleukin-4 (IL-4) and gamma interferon (IFN-γ), they are more likely to produce IL-10 and less likely to produce IFN-γ than equivalent FoxP3(-) cells.
7050 22861368 Multi-parameter flow cytometry was used to delineate CD4(+) T cell populations and phenotypes producing interferon (IFN)-γ, interleukin (IL)-2, tumour necrosis factor (TNF)-α and IL-4.
7051 22861368 Based on surface CD69 expression, infants demonstrated activation of vaccine antigen-specific CD4(+) T cells similar to adults.
7052 22861368 However, among infants, Boolean combinations of gates suggested that type 1 (Th-1) CD4(+) T cell responses were confined largely to TNF-α(+) IL-2(+) IFN-γ(-) or TNF-α(+) IL-2(-) IFN-γ(-) .
7053 22861368 A significantly lower percentage of polyfunctional T helper type 1 (Th1) responses (TNF-α(+) IFN-γ(+) IL-2(+) ) and type 2 (Th2) responses (IL-4) were present in the infants compared to adults.
7054 22861368 Moreover, a significantly higher percentage of infants' functional CD4(+) T cells were restricted to CD45RA(-) CCR7(+) CD27(+) phenotype, consistent with early-stage differentiated pertussis-specific memory CD4(+) T cells.

7060 22894948 The combination of chemotherapy with P10 immunization showed additive protective effect even after 30 d of infection or in anergic mice, rendering in general, increased production of IL-12 and IFN-γ and reduction of IL-4 and IL-10.
7061 22894960 The CD3(+), CD127(+), CD4(+)CD25(+) and CD4(+)Foxp3(+) cells were increased significantly post vaccination.
7062 22894960 The plasma level of the transforming growth factor (TGF-β), but not interleukin (IL)-2, IL-4, IL-5, IL-10, IFN-γ, TNF-α, was also found to increase significantly after vaccination.
7063 22896622 In a Th2-skewed formalin-inactivated (FI)-RSV vaccination model, the prebiotic diet reduced RSV-specific Th2 cytokine (interleukin-4 [IL-4], IL-5, and IL-13)-producing CD4(+) T cells in the lung and the magnitude of airway eosinophilia at day 4 and 6 after infection.
7064 22896622 This was accompanied by a decreased influx of inflammatory dendritic cells (CD11b(+)/CD11c(+)) and increased numbers of IFN-γ-producing CD4(+) and CD8(+) T cells at day 8 after viral challenge.
7065 22896622 These findings suggest that specific dietary oligosaccharides can influence trafficking and/or effector functions of innate immune, CD4(+), and CD8(+) T cell subsets in the lungs of RSV-infected mice.
7066 22904313 Peripheral blood monocytes were treated with GM-CSF and IL-4 to yield immature DCs, which were matured by addition of LPS and CD40 ligand (CD40L), with or without ESAT-6.
7067 22904313 ESAT-6 inhibited LPS/CD40L-induced DC expression of costimulatory molecules, reduced DC-stimulated allogeneic T cell proliferation and IL-2 and IFN-γ production, and enhanced IL-17 production.
7068 22904313 ESAT-6 inhibited LPS/CD40L-induced DC production of IL-12 and enhanced that of IL-23 and IL-1β, without affecting secretion of TNF-α, IL-6, or IL-8 through specific interaction with immature DCs.
7069 22904313 Medium from ESAT-6-conditioned DCs increased IL-17 and reduced IFN-γ production by T cells stimulated with anti-CD3 plus anti-CD28, and ESAT-6-induced IL-17 production was blocked by neutralizing both IL-23 and IL-1β.
7070 22904313 ESAT-6 reduced LPS/CD40L-stimulated transcription of IL-12p35 and enhanced that of IL-23p19 through inhibition of IFN regulatory factor-1 and upregulation of activating transcription factor-2 and c-Jun, transcriptional regulators of IL-12p35 and IL-23p19, respectively.
7071 22904313 We conclude that ESAT-6 increases DC production of IL-23 and IL-1β while inhibiting that of IL-12, thus enhancing Th17 at the expense of protective Th1 responses.

7136 23251517 We found that vaccination of cattle with BCG overexpressing Ag85B induced higher production of IL-17 and IL-4 mRNA upon purified protein derivative (PPDB) stimulation of peripheral blood mononuclear cells (PBMCs) than vaccination with BCG.
7137 23252743 Immunization with the rTs-Adsp antigen induced both humoral and cellular immune responses, which manifested as elevated specific anti-rTs-Adsp IgG and IgE antibodies and a mixed Th1-Th2 response, as determined by Th1 (IFN-γ and IL-2) and Th2 (IL-4, IL-10, and IL-13) cytokine profiling, with the Th2 predominant.

7177 23439080 Cell-mediated immune responses at 2 (n=56) and 6 (n=54) months of age were examined by ELISpot assays for interferon(IFN)-γ, interleukin(IL)-2, and IL-4 responder cell frequencies to three antigens: hepatitis B surface antigen, tetanus toxoid, and phytohaemagglutinin (PHA).
7178 23439322 Obese DCs produced twofold more of the immunosuppressive cytokine interleukin (IL)-10 than lean controls, and in turn stimulated fourfold more IL-4-production from allogenic naive T cells.
7179 23453731 IN, but not IR, immunization of mice with 2/6-VLP alone induced antigen-specific IL-10 and IL-17 secreting T cells.
7180 23453731 IL-10-, in contrast to IL-17-, secreting T cells did not migrate to the mesenteric lymph nodes (MLN) whereas they were detected in cervical lymph nodes (CLN) and spleen.
7181 23453731 With the IN route, the adjuvant allowed to complete this profile with the secretion of IL-2 and IL-4, increased IL-17 secretion and induced antigen specific CD4+CD25+Foxp3+ and Foxp3- T cells in all studied organs (CLN, spleen and MLN) but did not impact on IL-10 secreting T cells.
7182 23453731 With the IR route, the adjuvant induced IL-2 and IL-17 secretion but, in contrast to the IN route, did not allow IL-4 production.

7191 23467777 The vaccine significantly enhanced the production of gamma interferon (IFN-γ) and interleukin 2 (IL-2) after one immunization and enhanced the production of IL-4 and IL-10 after two immunizations.
7192 23467777 In addition, real-time PCR indicated that the expression of major histocompatibility complex I (MHC-I), as well as that of CD40 and CD154 molecules, was significantly increased after one immunization, and the expressions of both MHC-I and MHC-II molecules were increased after two immunizations.
7193 23474022 The two molecules stimulated the proliferation of T-lymphocyte sub-sets (CD4/CD8) as well as the production of soluble mediators of Th1 (IL-2 and IFN-γ) and Th2 response (IL-4) in spleen cell culture supernatant.
7194 23474022 Furthermore, the two lipidated tripeptides enhanced the CD4, CD8, CD3 and CD19 cell populations as well as CD4/CD8 derived IL-2, IL-4, IFN-γ and TNF-α in whole blood of treated mice.
7195 23474022 Moreover, the two lipidated tripeptides enhanced the population of CD80 and CD86 in spleen-derived macrophages and did not show any hemolytic effect on rabbit RBCs.
7196 23474022 The two molecules stimulated the proliferation of T-lymphocyte sub-sets (CD4/CD8) as well as the production of soluble mediators of Th1 (IL-2 and IFN-γ) and Th2 response (IL-4) in spleen cell culture supernatant.

7198 23474022 Moreover, the two lipidated tripeptides enhanced the population of CD80 and CD86 in spleen-derived macrophages and did not show any hemolytic effect on rabbit RBCs.
7199 23486418 In addition, children with active TB had significantly elevated levels of C-reactive protein, α-2 macroglobulin, and haptoglobin, as well as hemoxygenase 1.
7200 23486418 Markers of innate immune activation (lipopolysaccharide [LPS] and lipopolysaccharide-binding protein [LBP]) were significantly lower in ETB than in PTB children.
7201 23486418 Although there were no significant differences between the two groups in their levels of cytokines (type 1 [gamma interferon (IFN-γ), tumor necrosis factor α (TNF-α), interleukin 2 (IL-2), and IL-12], type 2 [IL-4, IL-5, IL-13, and IL-33], and most type 17 [IL-17A, IL-22, IL-1β, and IL-6] and type 1 interferons [IFN-α and IFN-β]) or most of the cytokines associated with immune modulation (IL-10 and IL-20), pediatric TB was associated with elevated plasma transforming growth factor β (TGF-β), IL-21, and IL-23 levels.
7202 23497910 Specific cellular immunity was also induced after LTB-IAVe immunization, as evidenced by up-regulating of IL-1β, IL-8, and IL-4 expression in peripheral blood mononuclear cells (PBMCs) of vaccinated pigs.
7203 23499484 CXCL9 and CXCL10 were increased in the infection group and decreased in the infection-tumor group.
7204 23499484 Although SDF-1 and IL-4 were increased in the infection group, there was no significant change in expression in the infection-tumor group or the infection-metastasis group.
7205 23499484 These results suggest that T. spiralis infection reduced tumor growth and metastasis through a complex transition in cytokine regulation profiles including CXCL9, CXCL10, and CXCL13.
7206 23539949 No difference was observed in the level of IL-10 and IL-4 in immunized and GST control group.
7207 23541883 According to the results of IFN-γ, IL-4, total IgG, IgG1, and IgG2a measurement and the MTT assay, IL-22 obviously caused an increase in IFN-γ production and a decrease in IL-4 production before and after the challenge (p<0.05).
7208 23555672 C57BL/6 mice immunized with TcVac3 elicited a strong antigen-specific, high-avidity, trypanolytic antibody response (IgG2b>IgG1); and a robust antigen- and Tc-specific CD8(+)T cell response with type-1 cytokine (IFN-γ(+)TNF-α>IL-4(+)IL-10) and cytolytic effector (CD8(+)CD107a(+)IFN-γ(+)Perforin(+)) phenotype.
7209 23555672 Co-delivery of IL-12 and GMCSF cytokine adjuvants didn't enhance the TcVac3-induced resistance to T. cruzi.
7210 23555672 In chronic phase, vaccinated/infected mice exhibited a significant decline (up to 70%) in IFN-γ(+)CD8(+)T cells, a predominance of immunoregulatory IL-10(+)/CD4(+)T and IL10(+)/CD8(+)T cells, and presented undetectable tissue parasitism, inflammatory infiltrate, and fibrosis in vaccinated/infected mice.
7211 23577175 The pro-inflammatory cytokines tested Interleukin (IL)-6, IL17A, tumour necrosis factor (TNF)-α did not influence IFN-α responses except TNF-α, which promoted responses induced by FMDV.
7212 23577175 The haematopoietic cytokines Fms-related tyrosine kinase 3 ligand (Flt3-L) and granulocyte-macrophage colony-stimulating factor (GM-CSF) had enhancing effects on pDC activation at least in one of the protocols tested.
7213 23577175 Interestingly, also the Th2 cytokine IL-4 was an efficient promoter of pDC activity, while IL-10 was the only negative regulator of IFN-α in pDC identified.
7214 23583463 Total specific antibody, IgG1, IgG2a, IgG2b, IgM, interleukin-4 (IL-4) and interferon-gamma (IFN-γ) levels were examined by the ELISA method.
7215 23587997 On days 7, 14, 21, 28, 35 and 42 after the first vaccination, the lymphocyte proliferation, serum antibody titre and interferon-gamma and interleukin-4 were measured.

7218 23587997 The results showed that CMP40 and CMP50 at suitable dose could significantly promote lymphocyte proliferation, enhance serum antibody titre, and improve serum interferon-gamma and interleukin-4 concentrations.
7219 23588087 The ΔyscB mutant could induce the secretion of both Th1-associated cytokines (IFN-γ, IL-2 and TNF-α) and Th2-associated cytokines (IL-4 and IL-10).
7220 23595505 Genetic variants in toll-like receptor 2 (TLR2), TLR4, TLR9, and FCγ receptor II are associated with antibody response to quadrivalent meningococcal conjugate vaccine in HIV-infected youth.
7221 23595505 Genetic variants associated with severity of meningococcal disease, including the IgG Fc receptor (FCγRII)-A484T, interleukin-10 (IL-10)-A1082G, -C819T, and -C627A, IL-4-C589T, mannose binding lectin-2 (MBL2)-A/O, -H/L, -P/Q, and -X/Y, toll-like receptor 2 (TLR2)-G2408A, TLR4-A12874G and -C13174T, and TLR9-T1237C and -T1486C were determined by real-time PCR (RT-PCR) for 271 HIV-infected subjects (median, 17 years).
7222 23595505 These findings suggest that for HIV-infected youth, the initial antibody response to MCV4 is associated with variants in TLR2 and TLR4 while the long-term response is associated with genetic polymorphisms in TLR9 and FcγRIIa.
7223 23597085 For allergic individuals, allergen-stimulated T cells largely secrete IL-4, IL-5 and IL-13 (Th2-type cytokines), whereas non-allergics show predominant IFN-γ secretion (Th1-type).
7224 23597869 WITHDRAWN: Co-administration of CCL5 and IL4 enhances DNA vaccine-induced protective immunity to Ascaris suum infection in mice.
7225 23602433 Quantitative real time PCR (qPCR) was used to determine transcript levels of IL-4, IL-6, IL-10, IL-12, IFN-γ and IFN-α from these cells.
7226 23607394 OprF-specific cellular responses in lung T cells isolated from mice immunized with AdC7OprF.RGD and AdC7OprF were similar for T helper type 1 (Th1) [interferon (IFN)-γ in CD8(+) and interleukin (IL)-12 in CD4(+)], Th2 (IL-4, IL-5 and IL-13 in CD4(+)) and Th17 (IL-17 in CD4(+)).
7227 23607482 No differences were observed in γδ T cells for the same patient in either situation, and a tendency to lower percentages of CD4(+) CD25(hi) T cells was observed under stability.
7228 23607482 A significantly lower production of tumour necrosis factor (TNF)-α and a significantly higher production of interleukin (IL)-5 was observed in asthma patients compared to healthy individuals, but no differences could be observed for IL-4, IL-13 or IL-10.
7229 23623859 We analyzed cellular (IL-2, IL-4, IL-5, IL-10, IL-12, IL-13, IFN-γ, TNF-α, GM-CSF) and humoral (IgG and IgM) immune response in 81 HIV-infected and 30 HIV-negative subjects, before (T0) and 4 weeks (T1) after receiving a single dose of trivalent MF59-adjuvanted influenza vaccine.
7230 23645103 The immunogenicity of the vaccine schedules was determined by measuring human immunodeficiency virus (HIV)-specific binding antibody levels and cytokine (interleukin-2 and interleukin-4) concentrations in peripheral blood, analyzing lymphocyte proliferation capacity against HIV epitopes and CD4(+)/CD8(+) cell ratio, and monitoring interferon-gamma levels at different times post-immunization.
7231 23686120 Analysis of the cytokines from mice immunized with NP-RAS showed a significant increase in the production of IFN-g and a decreased production of IL-10 and IL-4 compared to controls without RAS.
7232 23697573 Blood plasma cytokine concentrations did not differ between the ORS cases and controls for most cytokines measured (interleukin 4 [IL-4], IL-5, IL-10, IL-13, IL-1α, IL-8, tumor necrosis factor alpha [TNF-α], gamma interferon [IFN-γ], and IL-17A).
7233 23697573 However, ORS cases had higher levels of IL-10 and IL-3 than the controls at visits 1 and 2, even after all symptoms had subsided.
7234 23697573 Persistent higher levels of IL-10 and IL-3 in ORS cases suggest that host factors may have predisposed these individuals to develop ORS following influenza vaccination.
7235 23707076 Previous published studies showed that vaccination with Ag85A/ESAT-6 bio-beads induced antigen-specific IFN-γ, IL-17A, IL-6, TNF-α and IL-2 in splenocytes, but no significant increase in IL-4, IL-5 or IL-10.
7236 23707076 New results showed that antigen-specific IFN-γ release was induced by both CD4 and CD8 T cells in mice vaccinated with the Ag85A/ESAT-6 bio-beads.

7240 23749087 Compared to controls, the pcDNA/MIC11 immunized mice had high production of IFN-γ, IL-12, and IL-2 (p < 0.05), but not IL-4 (p > 0.05), indicating that a predominant Th1 type response was developed.
7241 23777951 Vaccine-induced cellular immune responses to parasite antigen were substantially decreased in basophil-depleted mice, with significant decreases in CD4(+) T-cell production of IL-4, IL-5, IL-10, and IFN-γ.
7242 23785233 Flow cytometric analyses revealed that spleen cells from BALB/c mice immunized with PLGA-rMOMP had elevated numbers of CD4+ and CD8+ T cell subsets, and secreted more rMOMP-specific interferon-gamma (Th1) and interleukin (IL)-12p40 (Th1/Th17) than IL-4 and IL-10 (Th2) cytokines.
7243 23804713 Although this vaccination induced CD4(+) CXCR5(+) PD-1(+) TFH cells in newborns, their frequency, as well as their Bcl6 expression and IL-21 and IL-4 mRNA induction, was decreased in early life.
7244 23804713 In addition, IL-4 dampened expression of Th17-related molecules in neonatal TFH cells, as TFH cells from immunized IL-4-deficient neonates displayed enhanced expression of RORγt and IL-17.
7245 23804713 Although this vaccination induced CD4(+) CXCR5(+) PD-1(+) TFH cells in newborns, their frequency, as well as their Bcl6 expression and IL-21 and IL-4 mRNA induction, was decreased in early life.
7246 23804713 In addition, IL-4 dampened expression of Th17-related molecules in neonatal TFH cells, as TFH cells from immunized IL-4-deficient neonates displayed enhanced expression of RORγt and IL-17.
7247 23825956 As early as two weeks after infection of these mice with L. major, T cell-specific and complete IL-10-deficient animals showed significantly increased lesion development accompanied by a markedly elevated secretion of IFN-γ or IFN-γ and IL-4 in the lymph nodes draining the lesions of the C57BL/6 or BALB/c mutants, respectively.
7248 23827994 The synthesised DNA was subcloned into the pET41a+ vector and expressed in Escherichia coli as a fusion to glutathione-S-transferase protein (GST).
7249 23827994 The production of interferon-γ was significantly higher in the immunised mice than in the control mice (> 1,300 pg/mL), but interleukin (IL)-10 and IL-4 production was not statistically different between the two groups.
7250 23844022 Stimulation of bone marrow-derived dendritic cells induced production of regulatory cytokines IL-10 and TGF-beta.
7251 23844022 Furthermore, eMOD prevented the development of airway inflammation, as demonstrated by attenuation of bronchoalveolar lavages eosinophil influx, peribronchial inflammatory infiltrate, and mucus secretion in lungs and IL-4 and IL-5 levels in lung cell cultures.

7267 23846426 Invariant natural killer T cells (iNKT cells) are unique lymphocytes with characteristic features, such as expression of an invariant T-cell antigen receptor (TCR) α-chain, recognition of glycolipid antigens presented by CD1d molecules, and ability to rapidly produce large amounts of cytokines, including interferon-γ (IFN-γ) and interleukin 4 (IL-4) upon TCR stimulation.
7268 23859640 The conjugates biased the immune responses towards Th1 and Th17 with respect to the prevalence of interferon-gamma (IFN-γ) and interleukin (IL)-17 (IL-17) over IL-4 and IL-10 levels.
7269 23873619 Expression of IL-2 (4.5-fold) and IFN-γ (3.2-fold), followed by IL-6 (1.7-fold) and IL-4 (1.6-fold), with downregulation of TNF-α and IL-10 was observed in response to F. gigantica infection in these animals.
7270 23873619 However, there was a sharp increase in the expression of the IL-4 (211.93 and 111.81-fold) and IL-6 mRNA (219.22 and 48.29-fold) to GST and FABP immunizations, respectively.
7271 23873619 A downregulation of the IL-1α, a Th1 cytokine in response to FABP and GST immunization in these calves, was also observed.
7272 23873619 Expression of IL-2 (4.5-fold) and IFN-γ (3.2-fold), followed by IL-6 (1.7-fold) and IL-4 (1.6-fold), with downregulation of TNF-α and IL-10 was observed in response to F. gigantica infection in these animals.
7273 23873619 However, there was a sharp increase in the expression of the IL-4 (211.93 and 111.81-fold) and IL-6 mRNA (219.22 and 48.29-fold) to GST and FABP immunizations, respectively.
7274 23873619 A downregulation of the IL-1α, a Th1 cytokine in response to FABP and GST immunization in these calves, was also observed.
7275 23883369 This study demonstrated that the enteric stage of T. spiralis infection could inhibit the proliferative response of spleen lymphocytes to hepatitis B surface antigen (HBsAg) and lead to lower levels of anti-HBsAg antibodies, interferon-γ, and interleukin (IL)-2, along with higher levels of IL-4 and IL-5.
7276 23911411 Dogs immunized with LBSap vaccine displayed high levels of IL-12 and IL-10 cytokines and CCL4, CCL5 and CXCL8 chemokines in the dermis.
7277 23911411 Herein, we inoculated dogs with Leishmania braziliensis antigens plus saponin (the LBSap vaccine), as well as with the vaccine components, and then used real-time PCR to evaluate the kinetics of dermal expression of mRNAs of cytokines (IL-12, IFN-γ, TNF-α, IL-4, IL-13, TGF-β and IL-10) and chemokines (CCL2, CCL4, CCL5, CCL21 and CXCL8) 1, 12, 24 and 48 h after inoculation.
7278 23911411 The LBSap vaccine induced high levels of IL-12 and IL-10 expression at 12 and 24 h, respectively.
7279 23911411 Furthermore, we observed positive correlations between IL-12 and IL-13 expression, IFN-γ and IL-13 expression, and IL-13 and TGF-β expression, suggesting that a mixed cytokine microenvironment developed after immunization with the vaccine.
7280 23911411 CCL4 and CXCL8 chemokine expression was up regulated by the LBSap vaccine.
7281 23926442 We examined the immune response mediated by macrophages (CD14+), natural killer cells (CD56+), and B lymphocytes (CD19+) by flow cytometry and assessed the expression of Th1 (IFN-γ, TNF-α, IL-2, and IL-12), Th2 (IL-4), and Treg (TGF-β) cytokines by flow cytometry and an enzyme-linked immunosorbent assay.
7282 23926442 The CD14+ TNF-α+ population was significantly increased (P < 0.04) when patients received the vaccine; IL-2 expression in both NK cells and in B lymphocytes was increased after a transient initial increase showed a nearly significant decrease (P < 0.07 and P < 0.06 respectively), whereas the CD19+ and CD56+ populations did not show significant changes.
7283 23928268 Twenty-four hours after the last challenge, BCG prevented the triggering of pro-inflammatory cytokines, probably by increasing Foxp3 and interleukin (IL)-10, modulating eosinophil infiltration and collagen fiber deposition, thus reducing airway hyperresponsiveness.
7284 23928268 These beneficial effects may be related to the increase in regulatory T cells and to IL-10 production in tandem with decreased Th2 cytokines (IL-4, IL-5, and IL-13).
7285 23928481 Our previous study established that Poly-ICLC is the most potent individual maturation stimulus for human DCs as assessed by an upregulation of CD83 and CD86, induction of interleukin-12 (IL-12), tumor necrosis factor (TNF), interferon gamma-induced protein 10 (IP-10), interleukmin 1 (IL-1), and type I interferons (IFN), and minimal interleukin 10 (IL-10) production.
7286 23928481 After incubation, the lymphocytes are washed off and the adherent monocytes are cultured for 5 days in the presence of interleukin-4 (IL-4) and granulocyte macrophage-colony stimulating factor (GM-CSF) to differentiate to immature DCs.
7287 23933364 IL-4 and IL-13 mediated down-regulation of CD8 expression levels can dampen anti-viral CD8⁺ T cell avidity following HIV-1 recombinant pox viral vaccination.
7288 23933364 We have shown that mucosal HIV-1 recombinant pox viral vaccination can induce high, avidity HIV-specific CD8(+) T cells with reduced interleukin (IL)-4 and IL-13 expression compared to, systemic vaccine delivery.
7289 23933364 Out of a panel of T cell avidity markers tested, only CD8 expression levels were found to be enhanced on, KdGag197-205 (HIV)-specific CD8(+) T cells obtained from IL-13(-/-), IL-4(-/-) and signal transducer and, activator of transcription of 6 (STAT6)(-/-) mice compared to wild-type (WT) controls following, vaccination.
7290 23933364 Elevated CD8 expression levels in this instance also correlated with polyfunctionality, (interferon (IFN)-γ, tumour necorsis factor (TNF)-α and IL-2 production) and the avidity of HIVspecific CD8(+) T cells.
7291 23933364 IL-13Rα2) vaccines significantly enhanced CD8 expression levels on HIV-specific CD8(+), T cells, which correlated with avidity.
7292 23933364 Using anti-CD8 antibodies that blocked CD8 availability on CD8(+), T cells, it was established that CD8 played an important role in increasing HIV-specific CD8(+) T cell avidity and polyfunctionality in IL-4(-/-), IL-13(-/-) and STAT6(-/-) mice compared to WT controls, following vaccination.
7293 23933364 Collectively, our data demonstrate that IL-4 and IL-13 dampen CD8 expression levels on anti-viral CD8(+) T cells, which can down-regulate anti-viral CD8(+) T cell avidity and, polyfunctionality following HIV-1 recombinant pox viral vaccination.

7416 24259557 Consistent with these results, WBM-fed mice had higher interferon-γ, tumor necrosis factor (TNF)-α, and interleukin (IL)-17A production and unchanged IL-4 production in their splenocytes after polyclonal (anti-CD3/CD28) or antigen-specific stimulation.
7417 24269617 Finally, A. galli significantly increased local mRNA expression of IL-4 and IL-13 and significantly decreased TGF-ß4 expression in the jejunum two weeks after infection with A. galli.

7422 24336457 Furthermore, an in vitro mechanistic study showed that wolfberry supplementation enhanced maturation and activity of antigen-presenting dendritic cells (DCs) in aged mice, as indicated by phenotypic change in expression of DC activation markers major histocompatibility complex class II, cluster of differentiation (CD) 40, CD80, and CD86, and functional change in DC production of cytokines interleukin-12 and tumor necrosis factor-α as well as DC endocytosis.
7423 24336457 Also, adoptive transfer of wolfberry-treated bone marrow DCs (loaded with ovalbumin(323-339)-peptide) promoted antigen-specific T cell proliferation as well as interleukin-4 and interferon-γ production in CD4(+) T cells.

7428 24338307 Furthermore, TV elicited higher level of cellular proliferative response together with elevated levels of IFN-γ, IL-4 and IL-5 indicating a Th1/Th2 balanced response.
7429 24349306 Mice were vaccinated with an adenoviral vector which encodes and displays the Friend Virus (FV) surface envelope protein gp70 (Ad.pIXgp70) in combination with adenoviral vectors encoding the interleukins IL4, IL5, IL6, IL7 or IL23.
7430 24349306 Mice co-immunized with adenoviral vectors encoding IL5 or IL23 showed increased neutralizing antibody responses while mice co-immunized with Ad.IL6 or Ad.IL23 showed improved FV-specific CD4(+) T cell responses compared to mice immunized with Ad.pIXgp70 alone.

7432 24357081 The results showed that CD40 as a molecular adjuvant significantly enhanced the production of serum anti-HA antibodies and increased the levels of the Th2 cytokines IL-4 and IL-6, suggesting that co-immunization with CD40 upregulated the humoral immune responses to the DNA vaccine in BALB/c mice.
7433 24357081 The titers of serum HA-specific antibodies were determined by ELISA, and the expression levels of the cytokines IL-2, IL-4, IL-6 and TNF-α were determined by real-time PCR.
7434 24357081 The results showed that CD40 as a molecular adjuvant significantly enhanced the production of serum anti-HA antibodies and increased the levels of the Th2 cytokines IL-4 and IL-6, suggesting that co-immunization with CD40 upregulated the humoral immune responses to the DNA vaccine in BALB/c mice.

7443 24370734 Moreover, rLdTPR reasonably stimulated PBMCs of cured Leishmania patients to produce IFNγ, IL-12, and TNF-α but not IL-4 or IL-10.
7444 24370734 On the other hand, the protein downregulated LPS-induced IL-10 as well as soluble L. donovani antigen-induced IL-4 production in PBMCs of Leishmania patients.
7445 24370734 The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFNγ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.

7453 24375062 Quantiation of IL-4, IL-10 and IFN-γ genes expression after immunization of mice with CFP-10 and ESAT-6 containing vectors.
7454 24386114 The systemic immune response was associated with increased production of Th1 (IFN-γ and IL-2), Th2 (IL-4) and Treg (IL-10) cytokines, indicating that not only Th1-type response was induced, but also Th2- and Treg-types responses were induced, and the splenocyte stimulation index (SI) was increased in the mice immunised with rTgACT.
7455 24421046 Macrophages incubated with sera from vaccinated infected mice exhibited M2 surface markers (CD16, CD32, CD200, and CD206), moderate proliferation, a low oxidative/nitrosative burst, and a regulatory/anti-inflammatory cytokine response (interleukin-4 [IL-4] plus IL-10 > tumor necrosis factor alpha [TNF-α]).
7456 24421046 In comparison, macrophages incubated with sera from nonvaccinated infected mice exhibited M1 surface markers, vigorous proliferation, a substantial oxidative/nitrosative burst, and a proinflammatory cytokine response (TNF-α ≫ IL-4 plus IL-10).
7457 24421046 Macrophages incubated with sera from vaccinated infected mice exhibited M2 surface markers (CD16, CD32, CD200, and CD206), moderate proliferation, a low oxidative/nitrosative burst, and a regulatory/anti-inflammatory cytokine response (interleukin-4 [IL-4] plus IL-10 > tumor necrosis factor alpha [TNF-α]).
7458 24421046 In comparison, macrophages incubated with sera from nonvaccinated infected mice exhibited M1 surface markers, vigorous proliferation, a substantial oxidative/nitrosative burst, and a proinflammatory cytokine response (TNF-α ≫ IL-4 plus IL-10).
7459 24423464 The result show that the vaccine can stimulate mice to produce specific IgG in serum and remarkable special s-IgA in lung lavage fluid, at the same time, the contents of cytokines IL-2 and IFN-γ of the experimental group were significant higher than those of the control group (P < 0.01), however, the contents of cytokines IL-4 was not different to the all groups.
7460 24428931 IL-4 contributes to failure, and colludes with IL-10 to exacerbate Leishmania donovani infection following administration of a subcutaneous leishmanial antigen vaccine.
7461 24440206 Antigen-specific IgG1 and IgG2b subclass antibody levels, proportion of CD4 and CD8T cells producing IFN-γ in the splenocytes and IL-4, IFN-γ, IL-12 and TNF-α levels in the sera and in the supernatants from ex vivo splenocytes culture were all enhanced by the NP-coated PyTAM DNA vaccine.
7462 24440303 After two immunizations, the mice vaccinated with antigen plus mixed CpG/poly (I:C) adjuvant exhibited significantly stronger IFN-gamma responses and generated high-level CD4(+) cell responses for the cytokines IL-2, IL-4, and IFN-γ and CD8(+) T cell responses for the cytokines IL-2 and IFN-γ compared to the mice vaccinated with the corresponding antigen plus CpG or poly(I:C) alone.
7463 24448242 Two biologically active isoforms of IL-33 exist that are full-length or mature, but the ability of either isoform to function as a vaccine adjuvant that influences CD4 T helper 1 or CD8 T-cell immune responses is not defined.
7464 24448242 In addition, although both IL-33 isoforms drove robust IFN-γ responses, neither elevated secretion of IL-4 or immunoglobulin E levels.
7465 24448242 Further, both isoforms augmented vaccine-induced antigen-specific polyfunctional CD4(+) and CD8(+) T-cell responses, with a large proportion of CD8(+) T cells undergoing plurifunctional cytolytic degranulation.
7466 24448242 Moreover, IL-33 could expand the magnitude of antigen-specific CD8(+) T-cell responses and elicit effector-memory CD8(+) T cells.
7467 24453241 Vaccine-induced T cells produced IFN-γ, IL-2, TNF-α, IL-17, IL-4, IL-5, and IL-10.
7468 24465412 A TH2 immune response characterized by the secretion of IL-4 and IL-5 in medium of BLG reactivated splenocytes was detected after either oral or intranasal administration of LL-FnBPA+ BLG.
7469 24475071 Assessment of their prophylactic potentials revealed ∼ 90% decrease in parasitic burden in rLdEno vaccinated hamsters against Leishmania challenge, strongly supported by an increase in mRNA expression levels of iNOS, IFN-γ, TNF-α and IL-12 transcripts along with extreme down-regulation of TGF-β, IL-4 and IL-10.
7470 24478103 In this study, we found that macrophages, dendritic cells, neutrophils, and both CD8(+) and CD4(+) T cells recruited to Coccidioides posadasii-infected lungs of nonvaccinated and vaccinated mice contributed to the production of IL-10.
7471 24478103 The major IL-10-producing leukocytes were CD8(+) T cells, neutrophils, and macrophages in lungs of nonvaccinated mice, while both Foxp3(+) and Foxp3(-) subsets of IL-10(+) CD4(+) T cells were significantly elevated in vaccinated mice.
7472 24478103 Profiles of the recruited leukocytes in lungs revealed that only CD4(+) T cells were significantly increased in IL-10(-/-) knockout mice compared to their wild-type counterparts.
7473 24478103 Furthermore, ex vivo recall assays showed that CD4(+) T cells isolated from vaccinated IL-10(-/-) mice compared to vaccinated wild-type mice produced significantly higher amounts of IL-2, gamma interferon (IFN-γ), IL-4, IL-6, and IL-17A in the presence of a coccidioidal antigen, indicating that IL-10 suppresses Th1, Th2, and Th17 immunity to Coccidioides infection.
7474 24478103 Analysis of absolute numbers of CD44(+) CD62L(-) CD4(+) T effector memory T cells (TEM) and IFN-γ- and IL-17A-producing CD4(+) T cells in the lungs of Coccidioides-infected mice correlated with better fungal clearance in nonvaccinated IL-10(-/-) mice than in nonvaccinated wild-type mice.
7475 24478103 Our results suggest that IL-10 suppresses CD4(+) T-cell immunity in nonvaccinated mice during Coccidioides infection but does not impede the development of a memory response nor exacerbate immunopathology of vaccinated mice over at least a 4-month period after the last immunization.
7476 24485693 Flax oil, but not fish oil, decreased the expression of IL-4 and tended to decrease expression of osteopontin and IL-8.
7477 24488178 Lmdd-CD24 effectively increased the number of interferon (IFN)-γ-producing CD8(+) T cells and IFN-γ secretion.
7478 24488178 Lmdd-CD24 also enhanced the number of IL-4- and IL-10-producing T helper 2 cells.
7479 24493438 Several observations are remarkable: the high efficacy of local cytokines to induce an antitumor response in the absence of systemic toxicity; a surprisingly large number of cytokines possess antitumor activity in this assay (IL-1, IL-2, IL-4, IL-6, IL-7, TNF, LT, IFN-γ, MCAF, G-CSF, GM-CSF, IP-10); and in several models, cytokine-producing tumors were heavily infiltrated by T-lymphocytes that contributed to tumor destruction (for review see ref. 1).
7480 24493438 Currently, three cytokine gene therapy variations with IL-2, IL-4, TNF, IFN-γ, or GM-CSF genes are tested: transfected autologous tumor cells; transfected allogeneic tumor cells; and transfected autologous fibroblasts mixed with tumor cells as vaccine.

7483 24498941 Enzyme-linked immunosorbent spot was applied to determine the levels of IFN-γ, IL-2 and IL-4 secreted by splenic lymphocytes.
7484 24498941 The stimulation index of spleen lymphocytes and the levels of IFN-γ, IL-2 and IL-4 of pcDNA-Rv1733c-immunized mice were both higher than those of saline-immunized mice (P < 0.05).
7485 24498941 Enzyme-linked immunosorbent spot was applied to determine the levels of IFN-γ, IL-2 and IL-4 secreted by splenic lymphocytes.
7486 24498941 The stimulation index of spleen lymphocytes and the levels of IFN-γ, IL-2 and IL-4 of pcDNA-Rv1733c-immunized mice were both higher than those of saline-immunized mice (P < 0.05).
7487 24503579 In addition, E-specific IL-4 T-cell immune responses were detected by ELISPOT after protein boost and CD8(+) specific IFN-γ expression was observed by flow cytometry.
7488 24516564 Prevention of intestinal allergy in mice by rflaA:Ova is associated with enforced antigen processing and TLR5-dependent IL-10 secretion by mDC.
7489 24516564 Using TLR5(-/-) mDC the rflaA:Ova induced IL-10 secretion was shown to be TLR5 dependent.
7490 24516564 In co-cultures of IL-10(-/-) mDC with DO11.10 T cells the lack of rflaA:Ova-mediated IL-10 secretion resulted in enhanced levels of both TH2 (IL-4, IL-5) and TH1 (IL-2 and IFN-y) cytokines.
7491 24589970 No significant difference was observed in cytokine levels of IL-1β, IL-4, IL-6, IL-10, IL-12, IFN-γ, MIP-1, TNF-α, and prostaglandin E2 (PGE2) in sera between the two groups.
7492 24598447 Fusion protein of mutant B7-DC and Fc enhances the antitumor immune effect of GM-CSF-secreting whole-cell vaccine.
7493 24598447 In addition to its coinhibitory receptor, programmed death receptor 1 (PD-1), evidence suggests that B7-DC interacts with an unidentified costimulatory receptor on T cells.
7494 24598447 B7-DC mutants with selective binding capacity for the costimulatory receptor may be effective in stimulating antitumor immune responses, while avoiding the inhibitory effects of PD-1.
7495 24598447 In this study, we concomitantly administered a GM-CSF-secreting whole-cell vaccine together with a fusion protein of mutant B7-DC and Fc portion (mB7-DC-Fc), which binds selectively to the costimulatory receptor.
7496 24598447 In addition, mB7-DC-Fc increased IFN-γ and IL-2 production and decreased IL-4 and IL-10 production in vitro, indicating that mB7-DC-Fc tips the Th1/Th2 balance toward Th1 dominance, which is more favorable for antitumor immunity.
7497 24598447 Furthermore, mB7-DC-Fc decreased the PD-1(+) proportion of CD8(+) T cells in vitro and tumor-infiltrating CD8(+) T cells in vivo, suggesting that mB7-DC-Fc may maintain tumor-infiltrating CD8(+) T cells in a nonexhausted state.
7498 24632732 In a PP cell culture system, b240 promoted the production of immunoglobulin A (IgA), interleukin (IL)-6, IL-10, interferon (IFN)-γ, and tumor necrosis factor, but not IL-4, IL-5, B-cell activating factors, IFN-α, IFN-β, and transforming growth factor-β1.
7499 24632732 The enhanced IgA production by b240 was attenuated by neutralizing IL-6, a potent IgA-enhancing cytokine. b240 stimulated DCs to produce an elevated amount of IL-6 in a Toll-like receptor (TLR) 2-, but not TLR4- or TLR9-dependent manner.
7500 24632732 Finally, we demonstrated that TLR2-mediated IL-6 production from PP DCs in response to b240 activated B cells to produce a large amount of IgA in a DC-B cell co-culture system.
7501 24633313 Accordingly, following T-cell vaccination the number of IFNγ-producing CD4(+) and CD8(+) T-cells was decreased by 1.6-1.8-fold, which was paralleled by 1.7-fold increases in IL-4-producing CD4(+) T-cells.
7502 24633313 In addition, the present study showed 5-7-fold increase in the CD8(+)CD45RO(+)CD62L(-) effector memory T-cells and central memory T-cells (both CD4(+) CD45RO(+)CD62L(+) T-cells and CD8(+)CD45RO(+)CD62L(+) T-cells) in RA patients, as compared with healthy individuals.
7503 24633313 We observed significant reduction in CD4(+) and CD8(+) central memory T-cells, as well as reduction in CD8(+) effector memory T-cells in vaccinated patients in the course of the treatment.
7504 24633313 We also demonstrated that CD4(+)CD25(+)FoxP3(+) regulatory T-cell levels were significantly up-regulated in the peripheral blood of RA patients following T-cell vaccination.
7505 24633313 However, CD4(+)CD25(-)FoxP3(+) Т-cell levels did not significantly change during the entire T-cell vaccination course.
7506 24636301 Additionally, positive prognostic indicators of bovine TB vaccine efficacy (i.e., responses measured after infection) include: reduced antigen-specific IFN-γ, iNOS, IL-4, and MIP1-α responses; reduced antigen-specific expansion of CD4(+) T cells; and a diminished activation profile on T cells within antigen stimulated cultures.
7507 24648995 In this study, we evaluated a TLR9 ligand (CpG oligodeoxynucleotide 1826, CpG) as an adjuvant for a partially protective DNA vaccine encoding a 26-kDa glutathione S-transferase of Schistosoma japonicum (pVAX1-Sj26GST).
7508 24648995 Vaccination with pVAX1-Sj26GST in combination with CpG inhibited Treg immunosuppressive function, upregulated the production of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-4, IL-10, IL-2 and IL-6, and decreased CD4+CD8+Foxp3+ expression in vitro, which may contribute to the escape from Treg-mediated suppression during vaccination, allowing expansion of antigen-specific T cells against pathogens.
7509 24649223 Peripheral blood mononuclear cells obtained by leukapheresis were cultured with granulocyte-macrophage colony-stimulating factor, interleukin-4, OK-432 and prostaglandin E2 to generate DCs, which were pulsed with autologous tumor lysates or tumor-specific peptides, such as WT1.
7510 24668365 Gene expression analysis showed that Salmonella treatment induced expression of iNOS, arginase-1 (ARG1), and IFN-γ in the spleen, but down-regulated IL-4 and TGF-β.
7511 24668365 Within the tumor, expression of iNOS, IFN-γ, and S100A9 was markedly increased, but ARG1, IL-4, TGF-β, and VEGF were inhibited.
7512 24668365 Gene expression analysis showed that Salmonella treatment induced expression of iNOS, arginase-1 (ARG1), and IFN-γ in the spleen, but down-regulated IL-4 and TGF-β.
7513 24668365 Within the tumor, expression of iNOS, IFN-γ, and S100A9 was markedly increased, but ARG1, IL-4, TGF-β, and VEGF were inhibited.
7514 24668628 Real-time PCR was used to detect the mRNA expression levels of the regulatory cytokines IL-4, IL-10, IL-12p40, and IFN-γ in pig peripheral blood mononuclear cells, after in vitro single vaccination and co-inoculation with PCV2 and the PRV.
7515 24668628 We found that PRV causes upregulation of IL-4, IL-12p40, and IFN-γ mRNA expression, while PCV2 causes mRNA upregulation of IL-4, IL-10, and IL-12p40.
7516 24668628 Real-time PCR was used to detect the mRNA expression levels of the regulatory cytokines IL-4, IL-10, IL-12p40, and IFN-γ in pig peripheral blood mononuclear cells, after in vitro single vaccination and co-inoculation with PCV2 and the PRV.
7517 24668628 We found that PRV causes upregulation of IL-4, IL-12p40, and IFN-γ mRNA expression, while PCV2 causes mRNA upregulation of IL-4, IL-10, and IL-12p40.
7518 24680943 Different time points after boosting, we measured serum antibodies in blood samples and separated splenocytes to detect lymphocyte proliferation and the production of IL-4, IL-10, IL-12, and IFN-γ in vitro.
7519 24680943 We also compared immunizations containing 20μl RV and 20μl RV adjuvanted with Re (5.00mg/kg) for the expression of CD4(+) and CD8(+) T-cell subsets at different time points.
7520 24680943 Results indicated that co-administration of Re significantly enhanced serum antibody titers, increased the CD4(+):CD8(+) ratio, and enhanced both proliferation responses and IL-4, IL-10, IL-12 and IFN-γ secretions.

7535 24688858 In this study we have used cytokine sequences from four marsupial genomes to identify mRNA sequences for key T regulatory, Th1 and Th2 cytokines interleukin 4 (IL-4), interleukin 6 (IL-6), interleukin 10 (IL-10) and interferon gamma (IFNγ) along with CD4 and CD8β.
7536 24688858 Phorbol myristate acetate/ionomycin was found to be the most effective mitogen to up-regulate the production of IL-4, IL-10 and IFNγ.
7537 24690608 Splenocytes from mice immunized with the VLPs also produced significantly greater quantities of interferon (IFN)-γ than interleukin (IL)-4 and IL-10.
7538 24709142 While the presence of memory CD4 T cell subsets has been associated with lasting protection in humans exposed to multiple bites from Anopheles mosquitoes infected with attenuated Plasmodium falciparum, memory CD8 T cells maintain protection induced with Plasmodium yoelii and Plasmodium berghei γ-spz in murine models.
7539 24709142 In this review, we discuss our observations that show memory CD8 T cells specific for antigens expressed by P. berghei liver stage parasites as an indispensable component for the maintenance of protracted protective immunity against experimental malaria infection; moreover, the provision of an Ag-depot assures a quick recall of memory T cells as IFN-γ-producing effector CD8 T cells and IL-4- producing CD4 T cells that collaborate with B cells for an effective antibody response.
7540 24718267 Mice with HSV-IL-2- and myelin oligodendrocyte glycoprotein (MOG)-induced demyelinating diseases demonstrated a similar pattern and distribution of demyelination in their brain, spinal cord (SC) and optic nerves (ONs).
7541 24718267 In contrast, no demyelination was detected in the ONs of myelin basic protein (MBP)- and proteolipid protein (PLP)-injected mice.
7542 24718267 Interferon-β (IFN-β) injections significantly reduced demyelination in brains of all groups, in the SCs of the MOG and MBP groups, and completely blocked it in the SCs of the PLP and HSV-IL-2 groups as well as in ONs of MOG and HSV-IL-2 groups.
7543 24718267 In contrast to IFN-β treatment, IL-12p70 protected the HSV-IL-2 group from demyelination, whereas IL-4 was not effective at all in preventing demyelination.
7544 24718267 Collectively, the results indicate that the HSV-IL-2 model and the MOG model complement each other and, together, provide unique insights into the heterogeneity of human MS.
7545 24729069 Compared to the pVAX1 control group, the PAR DNA vaccination group showed the higher levels of IgG, IgG1, IgG2a, IgE, IgM, stronger lymphocyte proliferation in mouse spleen, and larger production of IL-2, IL-4, IL-5, and IFN-γ in the supernatant of cultures from splenocytes.
7546 24740005 Cytokine ELISA measurements performed using in vitro PBMC culture supernatants demonstrated significantly higher levels of TNF-α, IL-2, IL-4, IL-6, IL-10, and TGF-β1 in the H. pylori-infected subjects, whereas IL-17A expression was not related to the subjects H. pylori-infection status.
7547 24747611 Further maximum protection was provided by SSG+KLD+MPL-A and it was most effective as depicted by 98.5% reduction in parasite load, a potent increase in IFN-γ levels and a significant decrease in IL-10 and IL-4 levels thus skewing the immune response towards Th1 type.
7548 24777831 PIAS1 and STAT-3 impair the tumoricidal potential of IFN-γ-stimulated mouse dendritic cells generated with IL-15.
7549 24777831 We report here that the tumoricidal potential of mouse DCs generated from myeloid precursors with GM-CSF and IL-15 (IL-15 DCs) can be triggered with the Toll-like receptor (TLR) 4 ligand lipopolysaccharide to a similar extent compared with that of their counterparts, conventionally generated with IL-4 (IL-4 DCs).
7550 24777831 In contrast, interferon (IFN)-γ induces the cytotoxic activity of IL-4 but not IL-15 DCs.
7551 24777831 Although the IFN-γ-STAT-1 signaling pathway is overall functional in IL-15 DCs, IFN-γ fails to induce iNOS expression in these cells. iNOS expression is negatively controlled in IFN-γ-stimulated IL-15 DCs by the cooperation between the E3 SUMO ligase PIAS1 and STAT-3, and can be partially restored with PIAS1 siRNA and STAT-3 inhibitors.
7552 24777831 PIAS1 and STAT-3 impair the tumoricidal potential of IFN-γ-stimulated mouse dendritic cells generated with IL-15.
7553 24777831 We report here that the tumoricidal potential of mouse DCs generated from myeloid precursors with GM-CSF and IL-15 (IL-15 DCs) can be triggered with the Toll-like receptor (TLR) 4 ligand lipopolysaccharide to a similar extent compared with that of their counterparts, conventionally generated with IL-4 (IL-4 DCs).
7554 24777831 In contrast, interferon (IFN)-γ induces the cytotoxic activity of IL-4 but not IL-15 DCs.
7555 24777831 Although the IFN-γ-STAT-1 signaling pathway is overall functional in IL-15 DCs, IFN-γ fails to induce iNOS expression in these cells. iNOS expression is negatively controlled in IFN-γ-stimulated IL-15 DCs by the cooperation between the E3 SUMO ligase PIAS1 and STAT-3, and can be partially restored with PIAS1 siRNA and STAT-3 inhibitors.
7556 24777970 Vaccination of patients with ovarian cancer with overlapping long peptides (OLP) from cancer-testis antigen NY-ESO-1 and poly-ICLC in Montanide-ISA-51 (Montanide) was found to consistently induce integrated immune responses (antibody, CD4(+), and CD8(+) T cells).
7557 24777970 Using detailed methods, we investigated the respective effects of poly-ICLC and Montanide adjuvant on pre- and postvaccine NY-ESO-1-specific CD4(+) T cells, because of their central function for induction and maintenance of both antibody and CD8(+) T cells.
7558 24777970 Polyclonal NY-ESO-1-specific CD4(+) T-cell lines were generated from 12 patients using CD154-based selection of precursors before and after vaccination with (i) OLP alone, (ii) OLP in Montanide, or (iii) OLP and poly-ICLC in Montanide.
7559 24777970 Vaccination with OLP alone did not elicit CD4(+) T-cell responses; it suppressed high-avidity CD4(+) T-cell precursors that recognized naturally processed NY-ESO-1 protein before vaccination.
7560 24777970 Emulsification of OLP in Montanide was required for the expansion of high-avidity NY-ESO-1-specific CD4(+) T-cell precursors.
7561 24777970 Poly-ICLC significantly enhanced CD4(+) Th1 responses while suppressing the induction of interleukin (IL)-4-producing Th2 and IL-9-producing Th9 cells.
7562 24788814 Cytokine diversity in the Th1-dominated human anti-influenza response caused by variable cytokine expression by Th1 cells, and a minor population of uncommitted IL-2+IFNγ- Thpp cells.
7563 24788814 To test for short-term variability, in vitro-stimulated influenza-specific human memory CD4+ T cells were sorted according to IL-2 and IFNγ expression, cultured briefly in vitro, and cytokine patterns measured after restimulation.
7564 24788814 Both cell types yielded IFNγ-secreting cells in Th1 conditions, but only IL-2+IFNγ- cells were able to differentiate into IL-4-producing cells.
7565 24789795 The levels of gamma interferon (IFN-γ), interleukin 2 (IL-2), and IL-12(p70) and the percentages of CD3(+) CD4(+) and CD3(+) CD8(+) cells in mice vaccinated with pVAX-CDPK5 were significantly increased.
7566 24789795 However, IL-4 and IL-10 were not produced in the vaccinated mice.
7567 24810641 Then, as tolerance to self-antigens can be broken by the activation of CD4 T-cell help, we tried to enhance the immunogenicity of legumain by the insertion of a foreign helper epitope, namely the p30 epitope from the tetanus toxin.
7568 24810641 The addition of the p30 helper epitope induced the specific production of IFN-γ by T cells, but did not significantly increase legumain-specific immunity activated after mutagenesis in the RGD motif which might be caused by simultaneous activation of a Th2 response demonstrated by the production of IL-4.
7569 24810641 However, the beneficial effect of the helper epitope on legumain-specific response was proved after the depletion of regulatory T cells by antibody against CD25 that preferentially stimulated Th1 immunity.
7570 24812238 Taurine reduced the expression of tumor necrosis factor-α mRNA in all 3 rearing patterns, IL-4 mRNA expression in the high-density group, and IL-10 in the low-density group (P < 0.05).
7571 24813415 The mice immunised with rTgRACK1 also displayed increased levels of rTgRACK1-specific IgA, total IgG, IgG1 and in particular IgG2a in their blood sera, increased production of IFN-γ, IL-2 and IL-4 but not IL-10 from their isolated spleen cells, and enhanced splenocyte proliferation in vitro. rTgRACK1-vaccinated mice were effectively protected against infection with T. gondii RH strain, showing over 50% reduction of tachyzoite burdens in their liver and brain tissues during a chronic infection, and also a 45% increase in their survivals during a lethal challenge.
7572 24814525 Our results show that administration of tuzin DNA protected BALB/c mice against L. donovani challenge and that protective immunity was associated with higher levels of IFN-γ and IL-12 production in comparison to IL-4 and IL-10.
7573 24815404 The results indicated that PPSB significantly enhanced specific antibody titers IgG, IgG1, IgG2b, and concentration of IL-2 and IL-4 in sera of mice immunized with pD-HSP90C (p<0.05).
7574 24882496 Pigs inoculated with pVAX1-EU-ORF3-ORF5 developed significantly higher (P<0.05) PRRSV-specific antibody responses, neutralizing antibodies and levels of IL-4 and IL-10 than those given pVAX1-EU-ORF3, pVAX1-EU-ORF5 or pVAX1.
7575 24882496 Moreover, pigs immunized with pVAX1-EU-ORF3-ORF5 had markedly increased levels of IFN-γ and IL-2 in serum and T-lymphocytes (CD3(+)CD4(+) and CD3(+)CD8(+) T cells) in peripheral blood.
7576 24888320 Wb20/22 elicited very high levels of IL-10 and diminished levels of IL-4 and IL-5 which could be the reason for low antibody titre.
7577 24899075 In addition, oral immunization with spray-dried NPs loaded with peanut proteins was associated with a significant decrease in splenic T(H)2 cytokines (interleukin 4 [IL-4], IL-5, and IL-6) and enhancement of both T(H)1 (gamma interferon [IFN-γ]) and regulatory (IL-10) cytokines.
7578 24901123 Our study found that the vaccine could promote the proliferation of antigen-specific T cells, enhance the killing activity of cytotoxic lymphocytes (CTL), promote Th1-type cells mediated secretion of cytokines IFN-gamma and IL-2 while inhibiting Th2-type cells mediated secretion of IL-4, and inhibit the secretion of TGF-beta.
7579 24906778 Co-administration of CS3 to BALB/c mice immunized with HBsAg significantly enhanced the influx of macrophages and dendritic cells in spleen, increased antigen-specific CD4+ and CD8+ cell numbers, and promoted splenocyte proliferation.
7580 24906778 The higher expression of interferon (IFN)-γ, lower expression of interleukin (IL)-4, and higher IgG2a/IgG1 ratio within the anti-HBsAg antibodies in mice immunized with HBsAg plus CS3 than those in mice receiving HBsAg alone indicated that CS3 induced a shift toward a Th1-biased immune response.
7581 24906994 After incubated with CotC-CsLAP2, the levels of IFN-γ, IL-6, IL-10, IL-17A, and TNF significantly increased in the supernatant of splenocytes isolated from mice orally treated with CotC-CsLAP2 spores, while there was no statistically significant difference of IL-4 level representing Th2 response among the groups.
7582 24910129 Here we demonstrate that activated but not resting B cells induce maturation of DCs with distinct features to polarize Th2 cells that secrete interleukin (IL)-5, IL-4 and IL-13.
7583 24910129 B-cell-induced maturation of DCs is contact dependent and implicates signalling of B-cell activation molecules CD69, B-cell-activating factor receptor, and transmembrane activator and calcium-modulating cyclophilin ligand interactor.
7584 24926810 Female BALB/c mice were immunized by intraperitoneal inoculation of rNspA, glutathione S-transferase (GST) or phosphate-buffered saline (PBS).
7585 24926810 The levels of specific immunoglobulin (Ig) A (SIgA), IgG, IgG1, IgG2a, IgG2b and IgG3 of mice in the rNspA group peaked at week six and were higher than those in the mice in the GST and PBS groups.
7586 24926810 The levels of stimulation index, interleukin-4 and interferon-γ in the culture supernatant of the spleen lymphocytes of the rNspA group increased in a time-dependent manner and were higher than those of the mice in the GST and PBS groups over the same period.
7587 24931647 Serum immunoglobulin (Ig)G titers and the secretions of both Th1-type (IFN-γ and IL-2) and Th2-type (IL-4 and IL-10) cytokines were higher in ducklings that had been vaccinated with LMS.
7588 24941746 BALB/c mice were subcutaneously immunized with Rv2628 protein, the production of IFN-gamma and IL-4 in the spleen cells was determined by Sandwich ELISA, in the Rv2628 immunized group, the level of IFN-gamma was significantly higher than that of IL-4 (P < 0.000 1).
7589 24962751 The results demonstrated that rTs-Hsp70 activated DC maturation that was characterized by the secretion of IL-1β, IL-12p70, TNF-α, and IL-6 and the increased surface expression of CD11c, MHC II, CD40, CD80, and CD86.
7590 24962751 The rTs-Hsp70-activated DCs enabled the stimulation, proliferation and secretion of Th1/2 cytokines (i.e., INF-γ, IL-2, IL-4 and IL-6) in CD4(+) T cells from T. spiralis-infected mice.
7591 24962751 This partial protection was correlated with Th1 and Th2 mixed anti-Ts-Hsp70-specific immune responses that included high titers of total IgG, IgG1 and IgG2a and increased levels of Th1/2 cytokines (i.e., IFN-γ, IL-2, IL-4, IL-6).
7592 24962751 The results demonstrated that rTs-Hsp70 activated DC maturation that was characterized by the secretion of IL-1β, IL-12p70, TNF-α, and IL-6 and the increased surface expression of CD11c, MHC II, CD40, CD80, and CD86.
7593 24962751 The rTs-Hsp70-activated DCs enabled the stimulation, proliferation and secretion of Th1/2 cytokines (i.e., INF-γ, IL-2, IL-4 and IL-6) in CD4(+) T cells from T. spiralis-infected mice.
7594 24962751 This partial protection was correlated with Th1 and Th2 mixed anti-Ts-Hsp70-specific immune responses that included high titers of total IgG, IgG1 and IgG2a and increased levels of Th1/2 cytokines (i.e., IFN-γ, IL-2, IL-4, IL-6).
7595 24967908 Arg1 expression was amplified by, but did not require, IL-4, and required de novo synthesis of unknown protein(s).
7596 24967908 Analysis of growth factors and their signaling pathways revealed that the Fibroblast Growth Factor Receptor 1 (FGFR-1) and Insulin-like Growth Factor 1 Receptor (IGF-1R) and a number of downstream signaling proteins were activated in splenic macrophages isolated from hamsters infected with L. donovani.
7597 24967908 Recombinant FGF-2 and IGF-1 increased the expression of arg1 in L. donovani infected hamster macrophages, and this induction was augmented by IL-4.
7598 24967908 Inhibition of FGFR-1 and IGF-1R decreased arg1 expression and restricted L. donovani replication in both in vitro and ex vivo models of infection.
7599 24967908 STAT6 was activated in infected macrophages exposed to either FGF-2 or IGF-1, and STAT6 was critical to the FGFR-1- and IGF-1R-mediated expression of arg1.
7600 24967908 The converse was also true as inhibition of FGFR-1 and IGF-1R reduced the activation of STAT6 in infected macrophages.
7601 24967908 Collectively, these data indicate that the FGFR/IGF-1R and IL-4 signaling pathways converge at STAT6 to promote pathologic arg1 expression and intracellular parasite survival in VL.
7602 24967908 Arg1 expression was amplified by, but did not require, IL-4, and required de novo synthesis of unknown protein(s).

7616 24968940 We found that helminth infection, characterized by the induction of the cytokine interleukin-4 (IL-4) and the activation of the transcription factor Stat6, reactivated murine γ-herpesvirus infection in vivo.
7617 24968940 IL-4 promoted viral replication and blocked the antiviral effects of interferon-γ (IFNγ) by inducing Stat6 binding to the promoter for an important viral transcriptional transactivator.
7618 24968940 We found that helminth infection, characterized by the induction of the cytokine interleukin-4 (IL-4) and the activation of the transcription factor Stat6, reactivated murine γ-herpesvirus infection in vivo.
7619 24968940 IL-4 promoted viral replication and blocked the antiviral effects of interferon-γ (IFNγ) by inducing Stat6 binding to the promoter for an important viral transcriptional transactivator.
7620 24972567 Mice were co-immunized with pCCL20 developed higher levels of core specific IFN-γ/IL-4 ratio and IL-2 release, IFN-γ producing cells, lymphocyte proliferation and cytotoxic Grenzyme B release in both draining lymph nodes and spleen cells of immunized mice.
7621 24982958 The efficacy of passive immunizations (colostral passive immunity by mare vaccination and artificial passive immunity by HI plasma administration) was evaluated based on clinical signs, complete blood count, blood gas analysis, serological response (ELISA), interleukin-4 (IL-4) and interferon gamma (IFN- γ ), total cell count of the bronchoalveolar lavage fluids (BALF) samples, reisolation rate of R. equi from BALF samples (CFU/mL), lung samples (CFU/gr), and lesion scores of the organs and tissue according to pathological findings after necropsy in the foals.
7622 24994009 Moreover, Δery induced an anti-Brucella-specific IgG (immunoglobulin G) response and stimulated the expression of interferon-gamma (INF-γ) and interleukin-4 (IL-4).
7623 24995396 In lymphocyte transformation assay, splenocytes of immunized mice exhibited a strong recall proliferative response with high amounts of IFN-γ, IL-12, IL-10 and IL-6 and very low levels of IL-5 and IL-4 production.
7624 25009233 Mice treated with the IL-4/anti-IL-4 immune complexes, shown previously to sustain levels of circulating IL-4, increased the RSV-induced AAM markers arginase-1 and mannose receptor and decreased the lung pathology.
7625 25066736 Allergic diseases are characterized by immune dysregulation, with increases in IL-4 and IL-6, both of which exert negative effects on Treg function.
7626 25073113 Quantitative-PCR and immunofluorescence staining results indicate that SARS-CoV is capable of replication in HL-CZ cells, and of displaying virus-induced cytopathic effects and increased levels of TNF-α, IL-4 and IL-6 two days post-infection.
7627 25073113 According to flow cytometry data, the HL-CZ cells also expressed angiotensin converting enzyme 2 (ACE2, a SARS-CoV receptor) and higher levels of the FcγRII receptor.
7628 25102355 Up to this time, they produced higher levels of IFN-γ, IL-2, IL-4, IL-17A and IL-10 and higher specific antibody response than control non-vaccinated mice.
7629 25111185 Peptide-specific IFN-γ production by splenic T cells obtained at 5 weeks post-immunization was quantified by ELISpot assay; additionally, the production of IL-4, IL-10 and TNF-α were quantified by cytokine bead array.
7630 25111185 Splenocytes derived from vaccinated HLA-A2/DRB1 transgenic mice exhibited peptide-specific cytokine production to the vast majority of the vaccine-encoded HLA class I- and class II-restricted T cell epitopes.
7631 25114104 In this article, we report that C57BL/6 mice lacking the adapter protein MyD88, which mediates signaling by TLRs and IL-1 family members, showed enhanced immunity to H. polygyrus infection.
7632 25114104 Alongside increased parasite expulsion, MyD88-deficient mice showed heightened IL-4 and IL-17A production from mesenteric lymph node CD4(+) cells.
7633 25114104 In addition, MyD88(-/-) mice developed substantial numbers of intestinal granulomas around the site of infection, which were not seen in MyD88-sufficient C57BL/6 mice, nor when signaling through the adapter protein TRIF (TIR domain-containing adapter-inducing IFN-β adapter protein) was also ablated.
7634 25114104 Mice deficient solely in TLR2, TLR4, TLR5, or TLR9 did not show enhanced parasite expulsion, suggesting that these TLRs signal redundantly to maintain H. polygyrus susceptibility in wild-type mice.
7635 25114104 Like IL-1R1(-/-) and MyD88(-/-) mice, animals lacking signaling through the type 1 IFN receptor (i.e., IFNAR1(-/-)) also developed intestinal granulomas.
7636 25114104 Hence, IL-1R1, MyD88, and type 1 IFN receptor signaling may provide pathways to impede granuloma formation in vivo, but additional MyD88-mediated signals are associated with inhibition of protective immunity in susceptible C57BL/6 mice.
7637 25118374 The titers of neutralizing antibodies against EV71 were determined using cytopathic effect-based neutralizing assay, and levels of cytokines (IFN-gamma and IL-4) secreted from in vitro-cultured rabbit splenic lymphocytes under antigen stimulation were also determined by ELISA.
7638 25118374 Levels of IFN-gamma and IL-4 in the group immunized with rVP1 plus chitosan were significantly higher than those in the group immunized with rVP1 only or those in the control groups.
7639 25118374 The titers of neutralizing antibodies against EV71 were determined using cytopathic effect-based neutralizing assay, and levels of cytokines (IFN-gamma and IL-4) secreted from in vitro-cultured rabbit splenic lymphocytes under antigen stimulation were also determined by ELISA.
7640 25118374 Levels of IFN-gamma and IL-4 in the group immunized with rVP1 plus chitosan were significantly higher than those in the group immunized with rVP1 only or those in the control groups.
7641 25122166 Immunisation of mice with peptides so-called B1, B2, B5, B6, T14, T15 and T16 induced high levels of total IgG, IgG1 and IgG2a (p<0.05) and a mixed Th1/Th2/Th17/Treg immune response, according to IFN-γ, IL-4, IL-17 and IL-10 levels, accompanied by increased CD62L+ T-cell populations.
7642 25148775 The cellular immune response was assessed by detection of IFN-γ, IL-10 and IL-4 in splenocyte culture supernatants.
7643 25149304 The most utilized Elispot assay is the interferon-gamma (IFN-γ) test, a marker for CD8(+) CTL activation, but Elispot can also be used to distinguish different subsets of activated T cells by using other cytokines such as T-helper (Th) 1-type cells (characterized by the production of IFN-γ, IL-2, IL-6, IL-12, IL-21, and TNF-α), Th2 (producing cytokines like IL-4, IL-5, IL-10, and IL-13), and Th17 (IL-17) cells.
7644 25149432 Subcutaneous inverse vaccination with PLGA particles loaded with a MOG peptide and IL-10 decreases the severity of experimental autoimmune encephalomyelitis.
7645 25149432 This problem has been overcome by DNA-based vaccines encoding for myelin autoantigens alone or in combination with "adjuvant" molecules, such as interleukin (IL)-4 or IL-10, that support regulatory immune responses.
7646 25149432 The aim of this work was to test the effectiveness of PLGA-NP loaded with the myelin oligodendrocyte glycoprotein (MOG)35-55 autoantigen and recombinant (r) IL-10 to inverse vaccinate mice with EAE.
7647 25149432 Moreover, they decreased the histopathologic lesions in the central nervous tissue and the secretion of IL-17 and interferon (IFN)-γ induced by MOG35-55 in splenic T cells in vitro.
7648 25151041 We have established that the efficacy of a heterologous poxvirus vectored HIV vaccine, fowlpox virus (FPV)-HIV gag/pol prime followed by attenuated vaccinia virus (VV)-HIV gag/pol booster immunisation, is strongly influenced by the cytokine milieu at the priming vaccination site, with endogenous IL-13 detrimental to the quality of the HIV specific CD8+ T cell response induced.
7649 25151041 In our vaccine system, the mutant IL-4C118 can bind to IL-4 type I and II receptors with high affinity, and transiently prevent the signalling of both IL-4 and IL-13 at the vaccination site.
7650 25151041 When this IL-4C118 adjuvanted vaccine was used in an intranasal rFPV/intramuscular rVV prime-boost immunisation strategy, greatly enhanced mucosal/systemic HIV specific CD8+ T cells with higher functional avidity, expressing IFN-γ, TNF-α and IL-2 and greater protective efficacy were detected.
7651 25151041 More interestingly, our recently tested IL-13Rα2 adjuvanted vaccine which only inhibited IL-13 activity, even though induced excellent high avidity HIV-specific CD8+ T cells, had a detrimental impact on the induction of gag-specific IgG2a antibody immunity.
7652 25151041 Our observations suggest that (i) IL-4 cell-signalling in the absence of IL-13 retarded gag-specific antibody isotype class switching, or (ii) IL-13Rα2 signalling was involved in inducing good gag-specific B cell immunity.
7653 25151041 We have established that the efficacy of a heterologous poxvirus vectored HIV vaccine, fowlpox virus (FPV)-HIV gag/pol prime followed by attenuated vaccinia virus (VV)-HIV gag/pol booster immunisation, is strongly influenced by the cytokine milieu at the priming vaccination site, with endogenous IL-13 detrimental to the quality of the HIV specific CD8+ T cell response induced.
7654 25151041 In our vaccine system, the mutant IL-4C118 can bind to IL-4 type I and II receptors with high affinity, and transiently prevent the signalling of both IL-4 and IL-13 at the vaccination site.
7655 25151041 When this IL-4C118 adjuvanted vaccine was used in an intranasal rFPV/intramuscular rVV prime-boost immunisation strategy, greatly enhanced mucosal/systemic HIV specific CD8+ T cells with higher functional avidity, expressing IFN-γ, TNF-α and IL-2 and greater protective efficacy were detected.
7656 25151041 More interestingly, our recently tested IL-13Rα2 adjuvanted vaccine which only inhibited IL-13 activity, even though induced excellent high avidity HIV-specific CD8+ T cells, had a detrimental impact on the induction of gag-specific IgG2a antibody immunity.
7657 25151041 Our observations suggest that (i) IL-4 cell-signalling in the absence of IL-13 retarded gag-specific antibody isotype class switching, or (ii) IL-13Rα2 signalling was involved in inducing good gag-specific B cell immunity.
7658 25156362 In contrast, substantial inhibition of IL-10, IL-4, and IL-13 expression and the absence of degranulated mast cells and less influx of eosinophils within the ears of immunized/challenged mice suggested a controlled anti-inflammatory response.
7659 25156362 L. mexicana Ag-stimulated lymph node cell culture from the immunized/challenged mice revealed induction of IFN-γ secretion by the CD4 and CD8 T cells compared with non-immunized/challenged mice.
7660 25159217 IL-4 and IL-13 receptors: Roles in immunity and powerful vaccine adjuvants.
7661 25159217 The roles of interleukin (IL)-4 and IL-13 during both innate and adaptive Th2 mediated immunity have received considerable scrutiny, however, mechanisms by which these cytokines influence the cellular interactions involved in negatively modulating the development of effective Th1 immunity are poorly characterized.

7669 25173481 In mice, the AS03- and AS25-adjuvanted i.m. vaccines generated a mixed Th1-Th2 response at 6 and 19 weeks after the last immunization as shown by the production of IgG1 and IgG2a antibodies as well as the production of IL-2, IL-4 and IFN-γ by CD4+ and CD8+ T cells.
7670 25173485 Analysis of IFN-γ, IL-4, IL-17 and TGF-β1 cytokines after immunization and compared with the control groups showed significant increments in pTgGR group.
7671 25173485 Additionally, T lymphocytes subpopulation CD4(+) T was positively recruited with significant percentage detected, while subset CD8(+) appeared not to be involved in response to this antigen.
7672 25174880 Here, we compared phenotype and functional characteristics of human monocyte-derived dendritic cells (DCs) generated in the presence of IL-4/GM-CSF (IL4-DCs) and IFNα/GM-CSF (IFN-DCs).
7673 25174880 We showed that IFN-DCs displayed semi-mature phenotype and expressed higher level of CD123, TNF-related apoptosis-inducing ligand (TRAIL) and B7-H1 molecules in comparison with IL4-DCs.
7674 25174880 LPS-stimulated IFN-DCs were characterized by greater production of Th1/pro-inflammatory (IFN-γ, IL-2, IL-1β, TNF-α, IL-17), Тh2/anti-inflammatory cytokines (IL-10, IL-5), hematopoietic growth factors (G-CSF) and chemokines (MCP-1).
7675 25174880 LPS-stimulated IFN-DCs possessed higher direct cytotoxic activity against TRAIL-sensitive tumor cell line Jurkat and similar cytotoxicity against TRAIL-resistant tumor HEp-2 cells.
7676 25174880 Besides, IFN-DCs and IL4-DCs equally induced apoptosis of activated CD4(+) and CD8(+) T cells.
7677 25178151 In addition, in pnd 17 spleen cells, αGalCer significantly stimulated the production of NK T cytokines, interleukin (IL)-4 and interferon (IFN)-γ, and promoted the proliferation of CD23(+) B cells, a subset of B cells enriched in germinal centres.
7678 25187406 The humoral immunity was evaluated by measuring the specific and total IgG levels, and also the T-cell immune response of mice was evaluated by measuring different cytokines such as IFN-γ, TNF-α, IL-4, IL-10 and IL-17.
7679 25187406 Co-administration of HPV-16 L1VLPs with R-LPS elicited the highest levels of splenocytes cytokines (IFN-γ, IL-4, IL-17 and TNF-α) and also effectively induced improvement of a Th1-type cytokine response characterized with a high ratio of IFN-γ/IL-10.
7680 25187406 The humoral immunity was evaluated by measuring the specific and total IgG levels, and also the T-cell immune response of mice was evaluated by measuring different cytokines such as IFN-γ, TNF-α, IL-4, IL-10 and IL-17.
7681 25187406 Co-administration of HPV-16 L1VLPs with R-LPS elicited the highest levels of splenocytes cytokines (IFN-γ, IL-4, IL-17 and TNF-α) and also effectively induced improvement of a Th1-type cytokine response characterized with a high ratio of IFN-γ/IL-10.
7682 25197336 The findings showed that the cytokine repertoire in the murine model was shifted after SIT, including stronger secretion of IFN-γ and IL-10, and a decreased production of IL-4 and IL-17.
7683 25200734 The peritoneal and consequently spleen CD19(+) cells are activated by the F. tularensis LVS infection to express the activation markers from MHC class II, CD25, CD54, CD69, and the co-stimulatory molecules CD80 and CD86.
7684 25200734 As early as 12 h post-infection, the peritoneal CD19(+) cells produce IFN-γ, IL-1β, IL-4, IL-6, IL-12, IL-17, IL-23, and TNF-α.
7685 25202304 The CD8(+) T cell-mediated protective immune response against CSP is dependent on the interleukin loop involving IL-4 receptor expression on CD8(+) cells and IL-4 secretion by CD4(+) T cell helpers.
7686 25202304 In the liver, the hepatic sinusoids are enriched with cells, such as dendritic, sinusoidal endothelial and Kupffer cells, that are able to cross-present MHC class I antigens to intrahepatic CD8(+) T cells.
7687 25206904 In the AdCpG(Aβ3-10)10 group, levels of interleukin (IL)-4 and IL-10 were increased, while those of IL-2 and interferon-γ were decreased.
7688 25206904 In the Aβ42 group, levels of IL-4, IL-10, IL-2 and interferon-γ were all increased.
7689 25206904 In the AdCpG(Aβ3-10)10 group, levels of interleukin (IL)-4 and IL-10 were increased, while those of IL-2 and interferon-γ were decreased.
7690 25206904 In the Aβ42 group, levels of IL-4, IL-10, IL-2 and interferon-γ were all increased.
7691 25208941 Interleukin-4 receptor alpha overexpression in human bladder cancer correlates with the pathological grade and stage of the disease.
7692 25208941 Previously, we have demonstrated that interleukin-4 receptor α (IL-4Rα) is overexpressed on a variety of human cancers and can serve as target for IL-4 immunotoxin comprised of IL-4 and a mutated Pseudomonas exotoxin.
7693 25208941 Two other chains of IL-4 receptor complex, IL-2RγC and IL-13Rα1, were absent or weakly expressed.

7700 25211769 CD4-positive T cells from mice primed with OVA-NPs produced substantial levels of IL-21 and IL-4, comparable to those from OVA-alum group.
7701 25211769 Moreover, when OVA-NPs-primed, but not OVA-alum-primed, B cells were cultured in the presence of anti-CD40 monoclonal antibody, IL-4, and IL-21, or LPS plus TGF-β in vitro, OVA-specific IgG1 or IgG2b antibody responses were elicited, suggesting that immunization with OVA-NPs modulates B cells to generate IgG1 and IgG2b responses.
7702 25211769 CD4-positive T cells from mice primed with OVA-NPs produced substantial levels of IL-21 and IL-4, comparable to those from OVA-alum group.
7703 25211769 Moreover, when OVA-NPs-primed, but not OVA-alum-primed, B cells were cultured in the presence of anti-CD40 monoclonal antibody, IL-4, and IL-21, or LPS plus TGF-β in vitro, OVA-specific IgG1 or IgG2b antibody responses were elicited, suggesting that immunization with OVA-NPs modulates B cells to generate IgG1 and IgG2b responses.
7704 25218192 The aims of this study were to address the protective immune response induced by S19 vaccination (n=10) and RB51 revaccination, in pregnant (n=9) and non-pregnant (n=10) S19 calfhood-vaccinated cattle as follows: evaluate the in vitro CD4(+) and CD8(+) T-lymphocytes specific proliferation, and in vitro expression of IFN-γ by CD4(+) and CD8(+) T-cells and IL-4 by CD4(+), CD8(+) and CD21(+) lymphocytes subset.
7705 25218192 Upon in vitro stimulation with γ-irradiated Brucella abortus 2308, blood mononuclear cells from S19 vaccinated and RB51 revaccinated cows exhibited significantly higher proliferation of CD4(+) and CD8(+) T-lymphocytes and CD4(+)IFN-γ(+) T-cells compared to non-vaccinated animals.
7706 25218192 RB51 revaccination, regardless of the pregnancy status, did not enhance the proliferation of CD4(+) or CD8(+) T-cells nor IFN-γ or IL-4 production.
7707 25218192 Data from the present study suggest that cattle's cellular immune response induced after brucellosis vaccination and revaccination is due to CD4(+) and CD8(+) T-lymphocytes, being CD4(+) T-cells the main source of IFN-γ.
7708 25218192 The aims of this study were to address the protective immune response induced by S19 vaccination (n=10) and RB51 revaccination, in pregnant (n=9) and non-pregnant (n=10) S19 calfhood-vaccinated cattle as follows: evaluate the in vitro CD4(+) and CD8(+) T-lymphocytes specific proliferation, and in vitro expression of IFN-γ by CD4(+) and CD8(+) T-cells and IL-4 by CD4(+), CD8(+) and CD21(+) lymphocytes subset.
7709 25218192 Upon in vitro stimulation with γ-irradiated Brucella abortus 2308, blood mononuclear cells from S19 vaccinated and RB51 revaccinated cows exhibited significantly higher proliferation of CD4(+) and CD8(+) T-lymphocytes and CD4(+)IFN-γ(+) T-cells compared to non-vaccinated animals.
7710 25218192 RB51 revaccination, regardless of the pregnancy status, did not enhance the proliferation of CD4(+) or CD8(+) T-cells nor IFN-γ or IL-4 production.
7711 25218192 Data from the present study suggest that cattle's cellular immune response induced after brucellosis vaccination and revaccination is due to CD4(+) and CD8(+) T-lymphocytes, being CD4(+) T-cells the main source of IFN-γ.
7712 25240754 Although comparable levels of antigen-specific IgG2a and IgG1 were observed in immunized mice, high amounts of IFN-γ, IL-12 and IL-6, no detectable level of IL-4 and very low levels of IL-10 and IL-5 were produced by splenocytes of vaccinated mice suggesting induction of a Th1 dominant immune response by DnaK.
7713 25242652 Spleen cells from mice receiving galactosylated liposomes were restimulated with OVA and showed significantly augmented levels of IFN-γ, IL-4, IL-5 and IL-6.
7714 25244501 Analysis of cytokine profiles revealed significant increases of IFN-γ, IL-4 and IL-17, while no significant changes were detected in TGF-β1.
7715 25244501 In cell-mediated response, both T lymphocytes subpopulations CD4(+) and CD8(+) were positively recruited as significant percentages were recorded in response to immunization with TgMDH.
7716 25253666 One month after booster vaccination (age 16 to 19 months), our study revealed significant increase in gamma interferon (IFN-γ) production in response to the PT and FIM antigens, a significant increase in IL-2 production with the PT, FHA, and PRN antigens, and a lack of significant interleukin-4 (IL-4) secretion with any of the antigens.
7717 25253667 Interleukin-10- and transforming growth factor β-independent regulation of CD8⁺ T cells expressing type 1 and type 2 cytokines in human lymphatic filariasis.
7718 25253667 INF individuals exhibited significant decreases in the frequencies of CD8⁺ T cells expressing tumor necrosis factor alpha (TNF-α), gamma interferon (IFN-γ), and interleukin-22 (IL-22) at baseline and/or in response to filarial antigens, compared with CP and EN individuals.
7719 25253667 In contrast, the same individuals exhibited significant increases in the frequencies of CD8⁺ T cells expressing IL-4, IL-5, IL-9, IL-13, and IL-21, compared with CP and/or EN individuals.
7720 25253667 Finally, the regulation of these responses appears to be independent of IL-10 and transforming growth factor β (TGF-β), since blockade of IL-10 or TGF-β signaling did not significantly alter the frequencies of type 1 or type 2 cytokine-expressing CD8⁺ T cells.
7721 25254971 We found no activation or even reduction in base-line expression for multiple molecules (IL-7, IL-4, IL-13, GATA3, ROR-γt, and CXCL12) at 2, 6 and 10 days post-infection.
7722 25254971 This selective impairment in type 2-related immune responses correlated with a significant activation of the genes for IL-1β, IL-6, IL-10, TNF-α, IFN-γ, as well as CXCR3- and CXCR1-related chemokines in inflamed tissues.
7723 25254971 The elevated angiopoietin (Ang)-2 expression and Ang-2/Ang-1 ratios suggested excessive inflammation and the loss of endothelial integrity.
7724 25255141 In this study, RH strain T. gondii rhoptry protein 17 was expressed in bacteria as a fusion with glutathione S-transferase (GST) and the recombinant proteins (rTgROP17) were purified via GST-affinity chromatography.
7725 25255141 The systemic immune response was associated with increased production of Th1 (IFN-γand IL-2) and Th2 (IL-4) cytokines, and enhanced lymphoproliferation (stimulation index, SI) in the mice immunised with rTgROP17.
7726 25261870 Compared to the standard i.n. recombinant fowlpox virus (FPV)-HIV vaccination, the FPV-HIV IL-13Rα2 or IL-4Rα antagonist adjuvanted vaccines that induced higher avidity CD8(+) T cells, also recruited significantly elevated MHCII(+) CD11c(+) CD11b(+) CD103(-) CD64(-) MAR-1(-) conventional DC (cDCs) to the lung mucosae (hierarchy: IL-4R antagonist>IL-13Rα2>unadjuvanted).
7727 25261870 In contrast, elevated CD11b(-) CD103(+) LDCs were detected in animals that received recombinant HIV vaccinia virus (rVV) or Modified Vaccinia Ankara virus (MVA) vector-based vaccines.
7728 25261870 Adoptive transfer studies indicated that CD11b(-) CD103(+) LDCs significantly dampened HIV-specific CD8(+) T cell avidity compared to CD11b(+) CD103(-) LDCs.
7729 25261870 Collectively; our observations revealed that rFPV vector prime and transient inhibition of IL-4/IL-13 at the vaccination site favoured the recruitment of unique LDCs, associated with the induction of high quality immunity.
7730 25268700 Based on this, we have previously identified several Th1-stimulatory proteins of Leishmania donovani -triose phosphate isomerase (TPI), protein disulfide isomerase (PDI) and elongation factor-2 (EL-2) etc. including heat shock protein 70 (HSP70) which induced Th1-type of cellular responses in both cured Leishmania patients/hamsters.
7731 25268700 Therefore, in this study, we checked whether HSP70 can further enhance the immunogenicity and protective responses of the above said Th1-stimulatory proteins.
7732 25268700 Since, in most of the studies, immunogenicity of HSP70 of L. donovani was assessed in native condition, herein we generated recombinant HSP70 and tested its potential to stimulate immune responses in lymphocytes of cured Leishmania infected hamsters as well as in the peripheral blood mononuclear cells (PBMCs) of cured patients of VL either individually or in combination with above mentioned recombinant proteins. rLdHSP70 alone elicited strong cellular responses along with remarkable up-regulation of IFN-γ and IL-12 cytokines and extremely lower level of IL-4 and IL-10.
7733 25268700 These observations indicated that vaccine(s) based on combination of HSP70 with Th1-stimulatory protein(s) may be a viable proposition against intracellular pathogens.
7734 25282449 WIV antigen alone induced mainly Th1 cytokines secretion, whereas BLP showed increased secretion of Th1 and Th2 cytokines, including interleukin (IL)-2, interferon-γ (IFN-γ) and IL-4, but not IL-10, and may be resembles a Th0 like response.
7735 25282449 BLP significantly promoted growth and expansion of natural killer cells and of CD4(+) and CD8(+) T-cell subsets in the spleen.
7736 25288644 The level of IFN-γ was higher in the GIT group than in the IsdB group (P<0.05), and the level of IL-4 was higher in the GIT group than in the GapC or TRAP groups (P<0.05).
7737 25293397 This protective immunity might be attributed to enhanced cell-mediated immunity, which is interpreted as increased lymphocytes proliferation, increased levels of Th1-type (IFN-γ) and Th2-type (IL-4) cytokines production and increased CD4(+) to CD8(+) ratios, resulting from the injection of four tandem repeats of the ectodomain of the conserved influenza matrix protein M2 (4×M2e) genetically fused to C-terminus of Mycobacterium tuberculosis HSP70 (mHSP70c).
7738 25307140 Interestingly, IL-4 and IFN-γ levels were obviously increased both in the serum and hippocampus of the AIV+Pre group (with a T helper-1 like response; Th1) compared with the Pre group (with a T helper-2 like response; Th2) at G14, whereas the expression of IL-6 and TNF-α, the proinflammatory factors, was significantly reduced.
7739 25355794 ChIL-18 markedly elevated serum hemagglutination inhibition (HI) titers and anti-hemagglutinin-neuraminidase (anti-HN)-specific antibody levels, induced the secretion of both Th1- (IFN-γ) and Th2- (interleukin-4) type cytokines, promoted the proliferation of T and B lymphocytes, and increased the populations of CD3(+) T cells and their subsets, CD3(+) CD4(+) and CD3(+) CD8(+) T cells.
7740 25369453 The production of eicosanoids from Arachidonic Acid (AA) can be hampered due to suppression of the enzyme phospholipase A2 by IL-4, an essential cytokine required for the differentiation of DCs.
7741 25369453 Thus addition of AA to the culture media is skewing the DCs towards the secretion of more IL-12 and less of IL-10 along with the restoration of eicosanoids levels in a COX-2 mediated pathway thereby enhancing the functionality of these cells to be used as a potent cellular vaccine.
7742 25400929 Total IgE, serum-specific inmunoglobulins (IgE and IgG4) to Dermatophagoides pteronyssinus and relevant cytokines (IFN-γ, IL-4, IL-5, IL-10 and IL-13) were assessed.
7743 25400929 No significant changes were observed in concentrations of total IgE, specific IgE or cytokines (IFN-γ, IL-4, IL-5, IL-10 and IL-13).
7744 25400929 Total IgE, serum-specific inmunoglobulins (IgE and IgG4) to Dermatophagoides pteronyssinus and relevant cytokines (IFN-γ, IL-4, IL-5, IL-10 and IL-13) were assessed.
7745 25400929 No significant changes were observed in concentrations of total IgE, specific IgE or cytokines (IFN-γ, IL-4, IL-5, IL-10 and IL-13).
7746 25449852 Circulating Th1, Th2 and Th17 effector cells were identified by intracellular staining for IFN-γ, IL-4 and IL-17, respectively, upon in vitro stimulation with PMA and calcium ionophore.
7747 25461799 CPMVs-immunized mice generated long lasting serum IgG, IgA, IgM as well as mucosal sIgA and also elicited a higher percentage of CD4+ T cell distribution in spleen.
7748 25461799 Our study revealed that in vitro CPMVs-activated dendritic cells were secreting T cell polarizing cytokines, IL-12p40, IL-4, IL-6 and IL-1β.
7749 25461799 Moreover, purified splenic CD4+ T cells of immunized mice also secreted IL-4, IL-13 and IL-17 cytokines, indicating the initiation of Th2 and Th17 cell mediated immune responses.
7750 25461799 CPMVs-immunized mice generated long lasting serum IgG, IgA, IgM as well as mucosal sIgA and also elicited a higher percentage of CD4+ T cell distribution in spleen.
7751 25461799 Our study revealed that in vitro CPMVs-activated dendritic cells were secreting T cell polarizing cytokines, IL-12p40, IL-4, IL-6 and IL-1β.
7752 25461799 Moreover, purified splenic CD4+ T cells of immunized mice also secreted IL-4, IL-13 and IL-17 cytokines, indicating the initiation of Th2 and Th17 cell mediated immune responses.
7753 25466267 In vitro, the MP-based vaccine significantly increased dendritic cell (DC) activation with up-regulated CD40 and CD80 expression and IL-12 production compared to alum-based vaccine.
7754 25466267 Moreover, subcutaneous and intramuscular immunizations with MP-based vaccine augmented Granzyme B, Th1-type cytokines (IL-2, IL-12, and IFN-γ), and Th2 cytokine IL-4 secretions.
7755 25475955 Previously, we have reported on the induction of strong immunogenicity in dogs upon vaccination with LdCen(-/-) including an increase in immunoglobulin isotypes, higher lymphoproliferative response, higher frequencies of activated CD4(+) and CD8(+) T cells, IFN-γ production by CD8(+) T cells, increased secretion of TNF-α and IL-12/IL-23p40 and, finally, decreased secretion of IL-4.
7756 25475955 The protection was associated with antibody production and CD4(+) and CD8(+) proliferative responses, as well as T cell activation and significantly higher production of IFN-γ, IL-12/IL-23p40 and TNF-α, which was comparable to responses induced by immunization with Leishmune(®), with significant differences when compared to control animals (Placebo).
7757 25493691 IL-17A expression in HIV-specific CD8 T cells is regulated by IL-4/IL-13 following HIV-1 prime-boost immunization.
7758 25493691 Our previous studies have shown that vaccination of IL-4 and IL-13 gene knockout (KO) mice can induce high-avidity HIV K(d)Gag197-205-specific CD8 T cells with better protective efficacy.
7759 25493691 In this study, when IL-13, IL-4, STAT6 KO, and wild-type BALB/c mice were prime-boost immunized with an HIV poxviral modality, elevated numbers of IL-17A(+) splenic K(d)Gag197-205-specific CD8 T cells were observed in all the KO mice compared with the wt BALB/c control.
7760 25493691 Similarly, when wt BALB/c mice were immunized with IL-13Rα2-adjuvanted HIV vaccines (that transiently inhibited IL-13 activity and induced high-avidity CD8 T cells with enhanced protective efficacy), elevated IL-17A(+) K(d)Gag197-205-specific CD8 T cells were detected both in the lung and the spleen.

7792 25500018 Lipopolysaccharide (LPS) and resiquimod (R-848) are TLR agonists that are recognized by TLR4 and TLR7, respectively.
7793 25500018 LPS and R-848 synergistically up-regulated the transcripts of interferon-β (IFN-β), IFN-γ, IL-4 and IL-1β as compared to the individual response (P<0.05).
7794 25503988 IL-28B, a member of the interferon (IFN)-λ family, has variable expression due to single nucleotide polymorphisms (SNPs).
7795 25503988 While type-I IFNs are well known to modulate adaptive immunity, the impact of IL-28B on B- and T-cell vaccine responses is unclear.
7796 25503988 In vitro, recombinant IL-28B increased Th1-cytokines (e.g.
7797 25503988 IL-4, IL-5, and IL-13), H1N1-stimulated B-cell proliferation (reduced 70%), and IgG-production (reduced>70%).
7798 25503988 Since IL-28B inhibited B-cell responses, we designed antagonistic peptides to block the IL-28 receptor α-subunit (IL28RA).
7799 25514604 Further PLA encapsulated antigens induced higher levels of cellular proliferation together with significant (P<0.0001) levels of cytokine response [PLA-TV induced high levels of IL-4(Th2) and IFN-γ (Th1) cytokines whereas PLA-FEP showed high levels of IL-5(Th2) and IFN-γ (Th1)] indicating a balanced response elicited by PLA antigens.
7800 25514671 The five most significant cytokines in decreasing order of importance were IL-7, IL-4, TNF-α, IL-13, and IL-17F.
7801 25532779 The antibody response towards the SC and the levels of Interferon (IFN)γ and Interleukin-4 expressed in peripheral blood mononuclear cells were assessed along or at the end of the study period respectively.
7802 25536171 B cell TLR1/2, TLR4, TLR7 and TLR9 interact in induction of class switch DNA recombination: modulation by BCR and CD40, and relevance to T-independent antibody responses.
7803 25536171 Here, we have addressed cross-regulation between two different TLRs or between a TLR and CD40 in CSR induction by using a B cell stimulation system involving lipopolysaccharides (LPS).
7804 25536171 Consistent with the requirement for dual TLR and BCR engagement in CSR induction, LPS, which engages TLR4 through its lipid A moiety, triggered cytosolic Ca2+ flux in B cells through its BCR-engaging polysaccharidic moiety.
7805 25536171 In the presence of BCR crosslinking, LPS synergized with a TLR1/2 ligand (Pam3CSK4) in CSR induction, but much less efficiently with a TLR7 (R-848) or TLR9 (CpG) ligand.
7806 25536171 In the absence of BCR crosslinking, R-848 and CpG, which per se induced marginal CSR, virtually abrogated CSR to IgG1, IgG2a, IgG2b, IgG3 and/or IgA, as induced by LPS or CD154 (CD40 ligand) plus IL-4, IFN-γ or TGF-β, and reduced secretion of class-switched Igs, without affecting B cell proliferation or IgM expression.
7807 25536171 The CSR inhibition by TLR9 was associated with the reduction in AID expression and/or IgH germline IH-S-CH transcription, and required co-stimulation of B cells by CpG with LPS or CD154.
7808 25536171 Unexpectedly, B cells also failed to undergo CSR or plasma cell differentiation when co-stimulated by LPS and CD154.
7809 25536171 Overall, by addressing the interaction of TLR1/2, TLR4, TLR7 and TLR9 in the induction of CSR and modulation of TLR-dependent CSR by BCR and CD40, our study suggests the complexity of how different stimuli cross-regulate an important B cell differentiation process and an important role of TLRs in inducing effective T-independent antibody responses to microbial pathogens, allergens and vaccines.
7810 25565478 Compared to mice immunized with naked PsaA, levels of IFN-γ, IL-17A and IL-4 in spleen lymphocytes, the systemic (IgG in serum) and mucosal (IgA in mucosal lavage) specific antibodies were enhanced significantly in mice inoculated with chitosan-PsaA.
7811 25566261 We report that Vγ9Vδ2 T cells induced expression of CD86, HLA-DR, and CD40 by B cells and stimulated the release of IL-4, IL-6, TNF-α, and IgG, IgA, and IgM.
7812 25566261 In contrast, Vγ9Vδ2 T cells induced expression of CD86 and HLA-DR and the release of IFN-γ, IL-6, and TNF-α by DC and these DC stimulated proliferation and IFN-γ production by conventional T cells.

7823 25610730 Injection of either fluorescently-labelled ACRs or blebs alone did not affect the number or distribution of migrated DC subsets from skin biopsies after 48 hours, but resulted in a general up-regulation of the co-stimulatory molecules CD83 and CD86 on skin DCs that had ingested apoptotic material.
7824 25610730 We have previously shown that i.d. administration of GM-CSF and IL-4 resulted in preferential migration of a mature and highly T cell-stimulatory CD11hiCD1a+CD14- dermal DC subset.
7825 25610730 Here, we found that co-injection of GM-CSF and IL-4 together with either ACRs or blebs resulted in uptake efficiencies within this dermal DC subset of 7.6% (±6.1%) and 19.1% (±15.9%), respectively, thus revealing a significantly higher uptake frequency of blebs (P < 0.02).
7826 25610730 Nevertheless, in contrast to i.d. administration of ACR, the injection of blebs lead to effective cross-presentation of MART-1 to specific CD8+ effector T cells.

7833 25632844 Using a super gene expression (SGE) system that we previously established to amplify the production of a recombinant protein, significant amounts of PAP-fused cytokines [human GMCSF, interleukin-2 (IL2), IL4, IL7 and mouse GMCSF and IL4] were obtained.
7834 25632844 We also investigated the in vivo therapeutic effects of multiple PAP-fused cytokines in a mouse prostate cancer model bearing prostate-specific antigen (PSA)- and PAP-expressing tumors.
7835 25632844 The simultaneous intraperitoneal administration of PAP-GMCSF, -IL2, -IL4 and -IL7 significantly prevented tumor induction and inhibited the tumor growth in the PAP-expressing tumors, yet not in the PSA-expressing tumors.

7859 25698486 We found that delivery of rPmp18D with VCG was more effective than with CpG+FL in up-regulating the expression of molecules critically involved in T cell activation and differentiation, including MHC II, CD40, CD80, and CD86, activation of TLRs and NLRP3 inflammasome engagement, and secretion of IL-1β and TNF-α but not IL-10 and IL-4. rVCG-Pmp18D-immunized mice elicited more robust antigen-specific IFN-γ, IgA and IgG2c antibody responses compared to CpG+FL-delivered rPmp18D.

7869 25733024 Cytokine profiling also showed a significant increase in the Th1 (IFN-γ, IL-2) and Th2 (IL-4, 10) responses in splenocytes of immunized mice upon stimulation with the rTsNd.
7870 25737202 Moreover, Th1 (TNF-α, IL-2, IFN-γ) and Th2 (IL-4, IL-5, IL-10) cytokines were expressed by both groups, yet only the intranasal group expressed the Th17 marker IL-17.
7871 25763999 Here, we used enzyme-linked immunosorbent assays with anti-CII IgG antibodies, quantified the expression levels of Th1, Th2, and Th3 cytokines, and performed flow cytometric analyses of different T-cell subsets, including Th1, Th2, Th17, Tc, Ts, Treg, and CD4(+)CD29(+)T cells to systemically evaluate humoral and cellular immune responses to pcDNA-CCOL2A1 vaccine in normal rats.
7872 25763999 Furthermore, no significant changes were observed in the expression levels of pro-inflammatory cytokines interleukin (IL)-1α, IL-5, IL-6, IL-12(IL-23p40), monocyte chemotactic protein (MCP)-1, macrophage inflammatory protein (MIP)-1α, regulated on activation in normal T-cell expressed and secreted (RANTES), receptor activator for nuclear factor-κB ligand (RANKL), and granulocyte colony-stimulating factor (G-CSF) or anti-inflammatory cytokines IL-4 and IL-10 in vaccinated normal rats relative to that in controls(P > 0.05).
7873 25763999 However, transforming growth factor (TGF)-β levels were significantly increased on days 10 and 14, while interferon (IFN)-γ and tumor necrosis factor (TNF)-α levels were significantly decreased on days 28 and 35 after vaccination(P < 0.05).
7874 25763999 Similarly, there were no significant differences in the percentages of Tc, Ts, Th1/Th2, and Th17 cells between the 2 groups(P > 0.05), with the exception of Treg cells, which were significantly reduced on days 14 and 21 after vaccination (P < 0.05), and CD4(+)CD29(+)T cells, which were significantly increased on days 7 and 14 after vaccination(P < 0.05).Taken together, these results suggested that pcDNA-CCOL2A1 vaccine did not markedly affect the balance of immune system components in vaccinated normal rats, indicating that this DNA vaccine may have clinical applications in the treatment of RA.
7875 25768031 To develop a more effective and safe vaccine against rabies, we have constructed a chimeric rabies virus-like particle (VLP), which containing glycoprotein (G) and matrix protein (M) of rabies virus (RABV) Evelyn-Rokitnicki-Abelseth (ERA) strain, and membrane-anchored granulocyte-macrophage colony-stimulating factor (GM-CSF), and it was named of EVLP-G.
7876 25768031 The EVLP-G also elicited significantly more IFN-γ- or IL-4-secreting CD4+ and CD8+ T cells than the sRVLP.
7877 25775390 Furthermore, sRCPS increased the levels of IL-4, IL-2, and IFN-γ in CD4(+)T cells and the level of IFN-γ in CD8(+)T cells.
7878 25775390 In addition, sRCPS enhanced the expression of CD40(+), CD80(+), CD86(+), MHC I and MHC II in dendritic cells (DCs) and upregulated the mRNA levels of MHC I, MHC II. sRCPS downregulated the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells. sRCPS increased both cellular and humoral immune responses by upregulating DC maturation, and suppressing the frequency of Treg cells.
7879 25784906 Mouse studies demonstrated that both EVLP-F and EVLP-L induced faster and larger virus-neutralizing antibodies (VNAs) responses and elicited greater numbers of CD4(+) and CD8(+) T cells secreting IFN-γ or IL-4 compared with a standard rabies VLP (sRVLP) containing only G and M.
7880 25796990 And the recombinant virus induced the production of HIV-1 p24 specific immunoglobulin G (IgG), IL-2 and IL-4.
7881 25799221 We observed a significant intracellular production of IL-4, but not IFN-γ, by CD4+ T-cells in spleen of mice following immunisation with Flg-2M2eh2M2ek.
7882 25816012 Concerted activity of IgG1 antibodies and IL-4/IL-25-dependent effector cells trap helminth larvae in the tissues following vaccination with defined secreted antigens, providing sterile immunity to challenge infection.
7883 25817256 4Aβ1-15-Derived Monoclonal Antibody Reduces More Aβ Burdens and Neuroinflammation than Homologous Vaccine in APP/PS1 Mice.
7884 25817256 The objective of our study was to observe the effects of 5C8H5, a novel monoclonal antibody derived from 4Aβ1-15, on brain Aβ pathology in an APP/PS1 mouse model of AD.
7885 25817256 The levels of proinflammatory factors, including IL-1β, IL-6, TNF-α and IFN-γ, were significantly decreased in the CNS, while the level of antiinflammatory IL-4 was increased.
7886 25845753 Two of the tested six fractions (namely F2 and F4) were characterized as polysaccharide-rich fractions, and were able to induce high levels of IFN-γ, and low levels of IL-4 and IL-10 in the spleen cells.
7887 25845753 The associations between LiHyp1/F2 and LiHyp1/F4 were able to induce an in vivo Th1 response, which was primed by high levels of IFN-γ, IL-12, and GM-CSF, by low levels of IL-4 and IL-10; as well as by a predominance of IgG2a antibodies in the vaccinated animals.
7888 25845753 Two of the tested six fractions (namely F2 and F4) were characterized as polysaccharide-rich fractions, and were able to induce high levels of IFN-γ, and low levels of IL-4 and IL-10 in the spleen cells.
7889 25845753 The associations between LiHyp1/F2 and LiHyp1/F4 were able to induce an in vivo Th1 response, which was primed by high levels of IFN-γ, IL-12, and GM-CSF, by low levels of IL-4 and IL-10; as well as by a predominance of IgG2a antibodies in the vaccinated animals.
7890 25847793 We aimed to compare their efficacy in treatment of multiple warts and investigate their effect on serum interleukin (IL)-4 and IL-12.
7891 25847793 After treatment, the control group showed the lowest serum IL-12 and IL-4 levels compared with the MMR- and PPD-treated groups with statistically significant difference in between.
7892 25847793 We aimed to compare their efficacy in treatment of multiple warts and investigate their effect on serum interleukin (IL)-4 and IL-12.
7893 25847793 After treatment, the control group showed the lowest serum IL-12 and IL-4 levels compared with the MMR- and PPD-treated groups with statistically significant difference in between.
7894 25855976 Activation of VLP-specific CD4+ and CD8+/IFN-γ T cells associated with Th1/Th2-balanced IFN-ɣ, IL-17, IL-4, and IL-13 was induced; in contrast, FI-EV71 induced only Th2-mediated neutralizing antibody against EV71 and low VLP-specific CD4+ and CD8+ T cell responses.
7895 25855976 Although antisera had no neutralizing activity against CVA16, the 3C-specific CD4+ and CD8+/IFN-γ T cells were identified, which could mediate protection against CVA16 challenge.
7896 25919308 This modified method enhanced staining of IL-2 and IL-4, but not IFNγ, tumor necrosis factor alpha (TNFα), or IL-5.
7897 25932130 The results were verified by measuring the contents of IL-4, IL-10, IL-17 and IFN-γ changed in both bronchoalveolar lavage fluid (BALF) and supernatant of splenocyte culture as well as level changes of specific IgE and IgG2a in the serum.
7898 25932130 In addition, we observed lower serum contents of the specific IgE antibody and lower levels of IL-4, IL-17 in BALF and splenic cells in mice undergone SIT, whereas specific IgG2a, IFN-γ and IL-10 in BALF and supernatant of splenocyte culture were higher as compared to the asthma group.
7899 25932130 The results were verified by measuring the contents of IL-4, IL-10, IL-17 and IFN-γ changed in both bronchoalveolar lavage fluid (BALF) and supernatant of splenocyte culture as well as level changes of specific IgE and IgG2a in the serum.
7900 25932130 In addition, we observed lower serum contents of the specific IgE antibody and lower levels of IL-4, IL-17 in BALF and splenic cells in mice undergone SIT, whereas specific IgG2a, IFN-γ and IL-10 in BALF and supernatant of splenocyte culture were higher as compared to the asthma group.
7901 25934108 Moreover, CVPS increased the expression of IL-2, IFN-γ, and IL-4 in CD4(+) T cells and IFN-γ expression in CD8(+) T cells.
7902 25934108 Additionally, CVPS enhanced CD40(+), CD80(+), and CD86(+) expression on DCs.
7903 25934108 In contrast, CVPS downregulated TGF-β mRNA expression and the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells.
7904 25934108 Taken together, these results indicate that administering CVPS as an adjuvant enhances both cellular and humoral immune responses via the TLR-2 and TLR-4 signalling pathways, thereby promoting DC maturation and suppressing TGF-β expression and Treg frequency.
7905 25936981 Immunization of BALB/c mice showed high levels of TNFα, IFNγ, interleukin (IL)-2, IL-6, and IL-4 in splenocyte supernatant culture and also high levels of serum specific anti-rFh15 IgG, IgG1, IgG2a IgE and IgM antibodies suggesting a mixed Th1/Th2 immune response.
7906 25939375 In lymphocyte proliferation assay, splenocytes from IP and SC-vaccinated mice displayed a strong recall proliferative response with high amounts of IL-4, IL-12 and IFN-γ production.
7907 25942359 A novel recombinant BCG-expressing pro-apoptotic protein BAX enhances Th1 protective immune responses in mice.
7908 25942359 In addition, it significantly enhanced Ag85B-specific IFN-γ enzyme-linked immunospot responses, IFN-γ secretion, IL-2 secretion and the ratio of Ag85B-specific IgG2b/IgG1, and it significantly decreased Ag85B-specific IL-4.
7909 25942359 In conclusion, these results suggest that the rBCG::BAX strain elicited predominantly a Th1 protective immune responses and might be a potential tuberculosis vaccine candidate for further study.
7910 25942636 We observed higher production of Th1 cytokines, such as TNF-α and IFN-γ, in vaccinated mice and no significant production of IL-4 and IL-5.
7911 25951230 In a head-to-head comparison with "IL-4 DCs" used routinely for clinical studies, IL-15 DCs were found to induce a more activated, cytotoxic effector phenotype in NK cells, in particular in the CD56bright NK cell subset.
7912 25951230 With the exception of GM-CSF, no significant enhancement of cytokine/chemokine secretion was observed following co-culture of NK cells with IL-15 DCs.
7913 25951230 IL-15 DCs, but not IL-4 DCs, promoted NK cell tumoricidal activity towards both NK-sensitive and NK-resistant targets.
7914 25951230 The observed lack of membrane-bound IL-15 on "gold-standard" IL-4 DCs and their consequent inability to effectively promote NK cell cytotoxicity may have important implications for the future design of DC-based cancer vaccine studies.
7915 25951230 In a head-to-head comparison with "IL-4 DCs" used routinely for clinical studies, IL-15 DCs were found to induce a more activated, cytotoxic effector phenotype in NK cells, in particular in the CD56bright NK cell subset.
7916 25951230 With the exception of GM-CSF, no significant enhancement of cytokine/chemokine secretion was observed following co-culture of NK cells with IL-15 DCs.

7920 25951230 With the exception of GM-CSF, no significant enhancement of cytokine/chemokine secretion was observed following co-culture of NK cells with IL-15 DCs.
7921 25951230 IL-15 DCs, but not IL-4 DCs, promoted NK cell tumoricidal activity towards both NK-sensitive and NK-resistant targets.
7922 25951230 The observed lack of membrane-bound IL-15 on "gold-standard" IL-4 DCs and their consequent inability to effectively promote NK cell cytotoxicity may have important implications for the future design of DC-based cancer vaccine studies.
7923 25954597 Thus, we engineered a collection of lentivectors that simultaneously co-expressed an antigen, a PD-L1-silencing shRNA, and various T cell-polarising cytokines, including interferon γ (IFNγ), transforming growth factor β (TGFβ) or interleukins (IL12, IL15, IL23, IL17A, IL6, IL10, IL4).
7924 25954597 In a syngeneic B16F0 melanoma model and using tyrosinase related protein 1 (TRP1) as a vaccine antigen, we found that simultaneous delivery of IL12 and a PD-L1-silencing shRNA was the only combination that exhibited therapeutically relevant anti-melanoma activities.
7925 25959574 After challenge with E. tarda, live cell (LC)-vaccinated fish showed high survival rates, high IFN-g and T-bet gene expression levels, and increased cytotoxic T lymphocytes (CTLs).
7926 25959574 In addition, FKC vaccination induced high IL-4/13A and IL-10 expression levels and increased antibody titers, whereas Th1-like responses were suppressed.
7927 25965393 Monocytes were directly induced to self-differentiate into DCs (SmartDC-TRP2) upon transduction with a tricistronic LV encoding for cytokines (granulocyte macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4)) and a melanoma antigen (tyrosinase-related protein 2 (TRP2)).
7928 26022514 In mice, BSG demonstrated a similar capacity of inducing pathogen-specific serum IgG antibody response, spleen CD3(+) and CD4(+) T cell responses, induce secretion of gamma interferon and interleukin-4, and protection levels against Brucella melitensis 16M challenge, as the attenuated B. suis live vaccine.
7929 26034171 Besides promoting Th2 programs, IL-4 is captured by the IL-4 heteroreceptor (IL-4Rα/IL-13Rα1) expressed on dendritic cells and instigates IL-12 downregulation.
7930 26040192 Mice only immunized with pVAX1-SOD presented increased frequencies of CD4(+) IFN-γ(+), CD8(+)IFN-γ(+) and CD8(+)IL-4(+) lymphocytes; moreover, high levels of IgG2a were detected.
7931 26040192 After challenge, mice that were immunized with pVAX1-SOD had increased frequencies of the CD4(+)IL-4(+), CD8(+)IFN-γ(+) and CD8(+)IL-4(+) T lymphocytes.
7932 26040192 Mice only immunized with pVAX1-SOD presented increased frequencies of CD4(+) IFN-γ(+), CD8(+)IFN-γ(+) and CD8(+)IL-4(+) lymphocytes; moreover, high levels of IgG2a were detected.
7933 26040192 After challenge, mice that were immunized with pVAX1-SOD had increased frequencies of the CD4(+)IL-4(+), CD8(+)IFN-γ(+) and CD8(+)IL-4(+) T lymphocytes.
7934 26041038 The supernatant was then assayed for gamma interferon (IFN-γ), interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-α), IL-4, IL-6, IL-10, and IL-17A.
7935 26041038 In addition, IL-6 concentrations were higher while IL-2 and IFN-γ concentrations were significantly lower in those with nonmeningeal disseminated disease diagnosed within 12 months than in those with acute pneumonia (for all, P < 0.05).
7936 26053794 Upon analysis of spleen cells, both, vaccination and treatment with rEmP29, resulted in low ratios of Th2/Th1 (IL-4/IFN-γ) cytokine mRNA and low levels of mRNA coding for IL-10 and IL-2.
7937 26072304 Serum from chickens immunized with pVAX1-MIC2 and rEmMIC2 protein displayed significantly high levels of IL-2, IFN-γ, IL-10, IL-17, TGF-β and IL-4 (P<0.05) compared to those of negative controls.
7938 26072430 Furthermore, DA39 showed higher expression of Ifng and Il12 mRNA at week 8 post-infection while the ratio of its Ifng/Il4 mRNA expressions was higher than other strains.
7939 26099574 Both clones showed a specific production of interferon-gamma (IFN-γ), interleukin-12 (IL-12) and granulocyte/macrophage colony-stimulating factor (GM-CSF) after in vitro spleen cells stimulation, and they were able to induce a partial protection against infection.
7940 26099574 Protection was associated with an IL-12-dependent production of IFN-γ, mediated mainly by CD8(+) T cells, against parasite proteins.
7941 26099574 Protected mice also presented low levels of IL-4 and IL-10, as well as increased levels of parasite-specific IgG2a antibodies.
7942 26104380 To date, recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF) combined with interleukin-4 (rhIL-4) has been a classic culture combination to DCs.
7943 26104380 What's more, we conclude that IFN-λ1 combined with GM-CSF and IL-4 can induce DCs maturation, which could become a possibility to be applied to the autologus dendritic cell vaccine to treat chronic hepatitis B.
7944 26104380 To date, recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF) combined with interleukin-4 (rhIL-4) has been a classic culture combination to DCs.
7945 26104380 What's more, we conclude that IFN-λ1 combined with GM-CSF and IL-4 can induce DCs maturation, which could become a possibility to be applied to the autologus dendritic cell vaccine to treat chronic hepatitis B.
7946 26115373 In general, an inverse correlation was observed between IFN-γ, IL-4, IL-17, KC, MIP-2 and LIX mRNA expression and H. suis colonization density, whereas lower IL-10 expression levels were observed in partially protected animals.
7947 26148331 We observed that at d 3-4 post vaccination, 6 genes were down-regulated, namely APC, CD3G, FASLG, IL7, CD8A and TLR1.
7948 26148331 Meanwhile at 6-7 days post vaccination, 9 genes were significantly up-regulated, including RIPK2, TGFB1, MICB, SOCS1, IL2RA, MS4A1, PTPRC, IL2 and IL8.
7949 26148331 By days 12-15 the genes RIPK2, IL4, IL12B and TLR2 were overexpressed.
7950 26150163 A novel cytokine, GIFT4, engineered by fusing GM-CSF and interleukin-4, was previously found to simulate B cell proliferation and effector function.
7951 26150163 Thus, the novel GPI-GIFT4-containging VLPs have the potential to be developed into a prophylactic HIV vaccine.
7952 26181095 Serum from chickens immunized with pVAX1-MIC7 and rEmMIC7 displayed significantly high levels of interleukin-2, interferon-γ, IL-10, IL-17, tumour growth factor-β and IL-4 (P < .05) compared to those of negative controls.
7953 26185907 With respect to immunomodulation, immature DCs incubated with wild type or L. plantarum-NY-ESO-1 upregulated the expression of co-stimulatory molecules and secreted a large amount of interleukin (IL)-12, TNF-α, but not IL-4.
7954 26185907 Moreover, they upregulated the expression of immunosuppressive factors such as IL-10 and indoleamine 2,3-dioxygenase.
7955 26188265 Furthermore, the highest levels of lymphocyte proliferation response, IL-4, IL-12 and IFN-γ production were induced following priming with the DNA vaccine and boosting with the rgD protein.
7956 26192354 LTT stimulation index (P ≤ 0.01) as well as CD4(+) and CD8(+) cells in flow cytometry (P<0.05) were significantly high and maximum in group D.
7957 26192354 Resiquimod significantly up-regulated the expression of IFN-α, IFN-β, IFN-γ, IL-1β, IL-4, iNOS and MHC-II genes (P<0.01).
7958 26196232 In comparison with naïve and live RSV re-infected mice, the high levels of eosinophils, neutrophils, plasmacytoid and CD11b(+) dendritic cells, and IL-4(+) CD4(+) T cells were found to be contributing to pulmonary inflammation in FI-RSV immune mice despite lung viral clearance.
7959 26227587 The splenic lymphocyte proliferation and the levels of IL-4, IL-6 and IL-12 of the inoculated mice were significantly increased, and the T- and B-cell populations were also elevated.
7960 26232344 Pups immunized with Advax had significantly higher splenocyte influenza-stimulated IFN-γ, IL-2, IL-4, and IL-10 production by CBA and a 3-10 fold higher frequency of IFN-γ, IL-2, IL-4 or IL-17 secreting T cells by ELISPOT.
7961 26263201 Sperm surface protein (Sp17) is a protein aberrantly expressed in primary as well as in metastatic lesions in >83% of ovarian cancer patients.
7962 26263201 However, one of the 6 peptides, hSp17111-142, induced high levels of antibodies and IFN-γ producing T cells (but not IL-17 or IL-4) both in C57BL/6 and in C57BL/6-HLA-A2.1 transgenic mice.
7963 26266750 Furthermore, vaccination generated high antibody titers of 1:12,800 against serotypes 1, 2, and 10 strains and enhanced production of interleukin 2 (IL-2) and IL-4 in ducks.
7964 26268065 Levels of interleukin (IL)-4, IL-10, IL-12p70, IL-17A and tumor necrosis factor (TNF)-α in serum were higher in the immunized mice compared to those in the adjuvant control group.
7965 26277277 The ratio of IgG1/IgG2c and profile of IL-4/IFN-γ in OMV (PagL)+Bap (1-487aa) formulation shows the humoral and cellular immune responses have been induced robustly and have created a full protection against A. baumannii ATCC 19606 and MDR AB-44 strains.
7966 26294082 Levels of serum tumour necrosis factor-alpha (TNF-α), interleukin-10 (IL-10), interleukin-4 (IL-4) as well as parasite-specific IgM, IgG, IgG1, IgG2a, IgG2b and IgG3 antibody responses were determined using enzyme-linked immunosorbent assay (ELISA).
7967 26312747 These mice also had significantly more IL-2 and less IL-4 Env-specific CD8+ T cells than controls, correlating with an increased percentage of Env-specific central memory CD4+ and CD8+ T cells.
7968 26318856 The PE25/PPE41 protein complex induced maturation of isolated mouse DCs in vitro, increasing expression of cell surface markers (CD80, CD86 and MHC-II), thereby promoting Th2 polarization via secretion of pro-inflammatory cytokines IL-4 and IL-10.
7969 26318856 In addition, PE25/PPE41 protein complex-activated DCs induced proliferation of mouse CD4(+) and CD8(+) T cells, and a strong humoral response in immunized mice.
7970 26332129 OM instruct DCs to stimulate Th1 responses via IL-12p70 production, which depends on the phosphorylation of p38, RM barely induce IL-12p70, but IL-10 and IL-4, and magnitude of ERK phosphorylation, which results in a Th2 bias.
7971 26373723 Both multistage vaccines induced very strong IL-12 and IFN-γ secretion from splenic cells; the Fc-tagged subunit vaccine induced a more effective Th1 immune response (IFN-γ, 910 pg/mL, and IL-12, 854 pg/mL) with a very low increase in IL-17 (∼0.1 pg/mL) and IL-4 (37 pg/mL) and a mild increase in TGF-β (543 pg/mL) compared to the BCG or ESAT6:HspX:His primed and boosted groups.
7972 26376930 Production of tumor necrosis factor alpha (TNF-α), gamma interferon, interleukin-17A (IL-17A), IL-10, and IL-4 was measured in CD4(+) effector memory (EM) T cells after 24 h by flow cytometry.
7973 26376930 We found the number of IL-17A-producing CD4(+) EM T cells, as well as that of cells simultaneously producing both IL-17A and TNF-α, to be significantly elevated in the Giardia-exposed individuals after 24 h of antigen stimulation.
7974 26376930 We conclude that symptomatic Giardia infection in humans induces a CD4(+) EM T cell response of which IL-17A production seems to be an important component.
7975 26382600 Immunized ducks triggered Omp-specific IgG, IgM, and IgA responses and raised IL-2 and IFN-γ levels in the serum coupled with IL-4 suppression.
7976 26388420 Subsequent to vaccination, the percentage of natural killer cells and T cells (CD3(+) CD4(+) CD8(-) and CD3(+) CD4(-) CD8(+) T cells) were significantly increased in the non-selected line but remained unchanged in the immunity-selected Large White line.
7977 26388420 Expression of interleukin (IL)-4 and IL-6 messenger RNA in hilar lymph nodes was significantly lower in the immunity-selected Large White line than in the non-selected line.
7978 26398499 The synthesized bis-heterocycles (8a-l) were subjected to in vitro lymphocyte proliferation assays followed by in vivo studies of the more active compounds (8g and 8h) to assess their influence on various aspects of the immune system like ex vivo splenocyte proliferation (T- and B-cell proliferation), antibody production (HA titer), delayed-type hypersensitivity reaction, T-cell subtypes (CD4 and CD8), cytokine production (IL-2, IFN-γ, and IL-4), NO (macrophage) production, and toxic effects.
7979 26404189 In addition, interleukin 4 (IL-4) levels in restimulated splenocytes were significantly less, while interferon-γ (IFN-γ), interleukin-10 (IL-10), and transforming growth factor-β (TGF-β) levels, as well as Foxp3 expression, were significantly greater than in the control groups.
7980 26421596 Analysis of cytokine profiles revealed significant increases of IFN-γ, IL-4 and IL-17, while no significant changes were detected in TGF-β1.
7981 26421596 Additionally, we found that pVAX-ESA10 enhanced the activation of CD4(+) and CD8(+) T cells and the expression of MHC-I and MHC-II molecules in spleen in mice.
7982 26424604 Multicolor flow cytometry was used to evaluate expression of CD4, CD25, and intracellular Foxp3 on PBMCs.
7983 26424604 Cell culture supernatants from BSA re-stimulated lymphocytes were evaluated for concentrations of IL-2, IL-4, IL-10, and IFN-γ.
7984 26450924 Additionally, the vaccine redirected Th2 (T-helper cell type 2) responses toward Th1 (T-helper cell type 1) responses with increases in IL-2, IFN-γ expression and decreases in IL-4 and IL-5 expression after immunization with tumour-Gal with CpG1826.
