19 1318491 A marked level of cell-mediated immunity (CMI) to Salmonella typhimurium-infection in mice, as determined by acquired resistance, delayed-type hypersensitivity, interleukin-2 production and interferon-gamma production, was induced by immunization with porin or viable cells but not with killed cells of S. typhimurium LT2.
20 1318491 Interleukin-1 (IL-1) production of macrophages to each immunogen was also examined; the result showed that immunization with porin or viable cells could induce a notable level of IL-1 production, while killed cells could not.
21 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.
22 1342705 Administration of IL-2 and IFN-gamma has beneficial effects in many infections mediated by viruses, bacteria, and protozoa.

26 1350916 BA elicited IFN gamma from CD4+ and CD8+ T cells, although CD4+ T cells secrete significantly more (p less than 0.05) IFN gamma than CD8+ T cells.
27 1350916 The ability of BA to elicit IFN gamma from human T cells was inhibited in the presence of anti-Tac, suggesting that BA also induces IL-2 secretion and that IL-2 is involved in BA-mediated IFN gamma secretion.
28 1350916 Exogenous IL-2 acted synergistically with BA to enhance IFN gamma secretion, suggesting that the amount of IL-2 released by BA alone was insufficient for optimal IFN gamma release.
29 1350916 Furthermore, addition of IL-2 to T cells from individuals with poor or absent responses to BA, including individuals infected with HIV-1, restored their ability to secrete IFN gamma in response to BA.

64 1356911 There was a direct quantitative correlation between the proliferative response of CD4+ and CD8+ T cells and their production of IFN-gamma.
65 1356911 IL-2 was produced in the cultures, the amounts being higher in the cultures of CD4+ than in those of CD8+ cells.
66 1356911 When proliferating, these clones did invariably produce IL-2 and IFN-gamma but no IL-4.
67 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.
68 1356911 The CD8+ T-cell response seems to depend on cytokines supplied by proliferating CD4+ T cells.
69 1358974 Role of neutrophils and CD4+ T lymphocytes in the primary and memory response to nonimmunogenic murine mammary adenocarcinoma made immunogenic by IL-2 gene.
70 1358974 NK cells and CD4+ lymphocytes are uninfluential, whereas CD8+ lymphocytes play only a minor role.
71 1358988 Anti-CD4, anti-CD8, or anti-interferon-gamma (IFN-gamma) antibodies or combinations of them were administered in the early stages of chronic infection of mice with a Candida albicans live vaccine strain, and the animals were monitored for course of primary infection, development of delayed-type hypersensitivity, resistance to reinfection, production of interleukin 2 (IL-2) and IFN-gamma in vitro by splenic lymphocytes, and levels of IL-2 and IFN-gamma transcripts in these cells.
72 1358988 CD4+ cell and IFN-gamma depletion resulted in the development of fatal candidiasis by the attenuated yeast vaccine.
73 1358988 Our data thus indicate that both IFN-gamma and CD4+ cells participate in resistance to primary infection with attenuated yeast cells and are critical in the induction of persistent systemic anticandidal immunity.
74 1373261 In the present study, primary antibody responses were assessed in cattle immunized with either 2 or 50 micrograms of gIV, and treated with multiple doses of IL-2 or combinations of IL-2 and IFN-alpha or IL-2 and IFN-gamma.
75 1373261 Addition of IFN-alpha or IFN-gamma to the IL-2/gIV/Avridine formulation did not affect any of the immune parameters tested.
76 1373261 As IFN-alpha is an effective immunoprophylactic agent for infectious bovine rhinotracheitis (IBR), combination vaccine-immunoprophylaxis may become feasible using IL-2 as a co-adjuvant.
77 1373261 In the present study, primary antibody responses were assessed in cattle immunized with either 2 or 50 micrograms of gIV, and treated with multiple doses of IL-2 or combinations of IL-2 and IFN-alpha or IL-2 and IFN-gamma.

83 1374103 To determine the functional differences between TACR and TDTH, we assessed IL-2 and IFN-gamma production from TACR and TDTH after stimulation with PPD in vitro.
84 1374103 These results suggest that CD4+ protective T cells generated by immunization with vBCG are characterized by the ability to produce IFN-gamma after stimulation with specific Ag.
85 1378932 The immune recognition of a molecule naturally presented as a monomeric or an oligomeric structure is analyzed using the human chorionic gonadotropin alpha subunit (hCG-alpha) as a model.
86 1378932 Indeed, hCG-alpha circulates as either a free subunit or combined to the beta subunit (hCG-beta) to form the dimeric hCG hormone.
87 1378932 Mice were immunized with the free hCG-alpha or the dimeric hCG alpha/beta, and their lymph node cells were challenged in vitro with either alpha subunits from different species, hCG or peptides spanning the entire primary structure of hCG-alpha.
88 1378932 Proliferation and IL-2 assays demonstrated that hCG-alpha-primed lymph node cells responded equally well to hCG-alpha and hCG alpha/beta, suggesting that both the free and combined hCG-alpha subunits are processed in a similar way.
89 1378932 In contrast, T cells primed with peptides mimicking immunodominant sites recognized differently the hCG-alpha and the hCG alpha/beta antigens.
90 1378932 Antibodies elicited against the hCG-alpha(59-92) or (32-59) peptide were capable of recognizing the alpha subunit in its free form but not in the alpha/beta hCG dimer.

129 1532378 On secondary exposure to schistosome antigen in vitro, these cells were capable of proliferating and secreting high levels of interferon-gamma (IFN-gamma) and interleukin-3 (IL-3).
130 1532378 These cells secreted high levels of IFN-gamma and IL-3 in vitro, but not IL-2 and IL-4.
131 1532378 Moreover these cells failed to secrete IFN-gamma and IL-3.
132 1533656 Schistosoma mansoni infection in the mouse has been shown to be accompanied by a down-regulation in parasite-Ag- and mitogen-induced Th1 cytokine secretion (IL-2 and IFN-gamma) with a simultaneous increase in the production of Th2 cytokines (IL-4, IL-5, and IL-10), suggesting a generalized imbalance in lymphocyte function.
133 1533656 When spleen cells (SC) from schistosome-infected SwMb-immunized animals were stimulated with SwMb, their production of IL-2 and IFN-gamma per CD4+ cell was found to be significantly reduced (by 45% and 59%, respectively) compared with the responses observed in immunized uninfected animals.
134 1533656 Moreover, SwMb-induced secretion of IL-4 per CD4+ cell was increased threefold in SC cultures from infected mice.
135 1533656 No myoglobin-induced IL-5 was detected in the same cultures.
136 1533656 Addition to SC cultures of a neutralizing mAb specific for IL-10 partly restored the suppressed IFN-gamma response to SwMb seen in infected mice, suggesting a role for IL-10 in the observed down-regulation.

184 1560752 Antigen-specific T lymphocytes were stimulated by CJ11 cells to proliferate and release interleukins (IL-2 and IL-3).
185 1560752 Thus, production of ML65hsp within the host cytoplasm resulted in association of the antigen with both MHC class I and MHC class II antigen-presenting structures and evoked both lymphocyte proliferation and cytotoxicity towards the antigen-presenting cell.
186 1561827 Animals treated with four weekly doses of liposome-formulated IL-2 (2.7 x 10(5) U kg-1 dose) overlapping two biweekly doses of an HSV-recombinant glycoprotein D (rgD) treatment demonstrated approximately 70% reduction in HSV-2 recurrent disease compared with placebo (p less than 0.005).
187 1593713 Increases in CD3+ T cell infiltration of the lamina propria and that of the CD4+ "Helper" subset which predominated were significant up to 3 months post-therapy and these cells showed evidence of increased immunological activation as shown by increased interleukin-2 receptor and MHC Class II antigen expression.
188 1593713 There were also significant increases in CD68+ macrophage and the incidence of CD22+ B cell aggregates but CD57+ NK cells were sparse both before and after therapy.
189 1593713 Also the degree of T cell infiltration (CD3, CD4 and CD8) was significantly greater in the eight patients deemed to have had a complete response compared to those seven with a partial response or treatment failure.
190 1615287 We have demonstrated that interferon-gamma (IFN-gamma) produced by natural killer (NK) cells and other immunocytes in response to the virus-encoded interleukin-2 (IL-2) is crucial to recovery.
191 1652468 In order to enhance the immunogenicity of recombinant viral protein, herpes simplex virus type 1 (HSV-1) glycoprotein D (gD), we genetically created a fusion protein consisting of gD and human IL-2.
192 1670604 Synergistic role of CD4+ and CD8+ T lymphocytes in IFN-gamma production and protective immunity induced by an attenuated Toxoplasma gondii vaccine.
193 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).
194 1670604 CD8+ cells, in contrast, produced less IFN-gamma and no detectable IL-2.
195 1670604 Nevertheless, they could be induced to synthesize IFN-gamma when exposed in culture to exogenous IL-2.
196 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.
197 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.

211 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).
212 1670604 CD8+ cells, in contrast, produced less IFN-gamma and no detectable IL-2.
213 1670604 Nevertheless, they could be induced to synthesize IFN-gamma when exposed in culture to exogenous IL-2.
214 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.
215 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.

255 1728399 We have administered the cytokines interleukin 2 (IL-2), alpha-interferon (IFN-alpha), and gamma-interferon (IFN-gamma) to mice and measured the alterations in hepatic drug-metabolizing enzyme activities.

266 1807258 Studies of human leprosy lesions in situ using suction-induced blisters: cell changes with IgM antibody to PGL-1 and interleukin-2 receptor in clinical subgroups of erythema nodosum leprosum.
267 1807258 During ENL reactions: a) the lesions in chronic ENL showed a decreased number of CD8+ (T-suppressor) cells and increased helper/suppressor ratio as compared to those in acute ENL and non-reactional leprosy; b) Tac peptide and IgM antibody to PGL-1 levels were elevated in the chronic ENL lesions; c) and systemic administration of corticosteroids appeared to cause a reduction in the intralesional CD4+ cell population and IgM antibody to PGL-1 but did not change CD8+ cell population and the levels of Tac peptide in the lesions.
268 1807258 We conclude that spontaneous lymphocyte activation in situ, primarily of decreased CD8+ and relatively increased CD4+ cells, are important features of chronic, recurrent ENL reactions and may be an intermittent or cyclic phenomenon during the reaction.
269 1810454 The cytokines IL1, IL2, IL6 and TNF alpha were also increased after BCG instillations.
270 1835213 Specific aspects of induced CMI responses investigated were macrophage activation (IL-1 production), helper T cell activation (IL-2 production), and release of soluble suppressor factor(s).

274 1851808 Immunization of BALB/c mice with a single dose of the Sabin type 1, type 2 or type 3 poliovirus vaccine strains stimulated cross-reactive T helper cell responses detected by both in vitro proliferation and interleukin (IL)-2/IL-4 production.
275 1878894 The percentage of lymphocytes with interleukin-2 (IL-2) receptors (CD25+) was significantly increased at 24 h and 48 h, compared to pre-instillation values (19 +/- 11% and 10 +/- 4% vs 3 +/- 3% respectively).
276 1878894 Natural killer cells (CD16+ and/or CD56+) and B cells (CD19+) were less numerous (10% and 19% at t0 respectively).
277 1888490 The potency of different rabies vaccines was measured via cell mediated immunity (CMI) assessed by the production of interleukin-2 (IL-2) by CD4+CD8- lymphocytes.
278 1901422 Nevertheless, antibodies to IL-2 as well as interleukin 4 (IL-4), significantly inhibited proliferation of synovial fluid lymphocytes by AP-MT.
279 1901422 We conclude that AP-MT induced proliferation by synovial fluid lymphocytes is mediated by both IL-2 and IL-4.
280 1901422 Nevertheless, antibodies to IL-2 as well as interleukin 4 (IL-4), significantly inhibited proliferation of synovial fluid lymphocytes by AP-MT.

282 1901883 In Leishmania major infections, cure vs progressive disease correlates with the expansion of Th1-like or Th2-like CD4+ populations, respectively.
283 1901883 Splenic lymphocytes from infected Lsh congenic C57BL/10 (Lshs;H-2b) and B10.L-Lshr (Lshr;H-2b) mice and MHC congenic non-curing B10.D2/n (Lshs;H-2d) mice were examined for the production of cytokines representative of these CD4+ populations (IL-2, IL-3, IL-4, IL-5, and IFN-gamma).
284 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.
285 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.

300 1967213 Purified gp120 suppressed the proliferative responses of the T-cell clones with concomitant suppression of IL-2 secretion; proliferative responses of CD8+ T cells preincubated with gp120 were not inhibited.

303 1967279 Host-reactive CD4+ and CD8+ T cell clones isolated from a human chimera produce IL-5, IL-2, IFN-gamma and granulocyte/macrophage-colony-stimulating factor but not IL-4.
304 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.
305 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.
306 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.
307 1967279 The finding that some of these clones produce significant levels of IL-5 but no IL-4 indicates that the IL-4 and IL-5 genes are not always coexpressed in activated human T cells.
308 1967279 Host-reactive CD4+ and CD8+ T cell clones isolated from a human chimera produce IL-5, IL-2, IFN-gamma and granulocyte/macrophage-colony-stimulating factor but not IL-4.

313 1972164 Secretion of IL-2, IL-4, and IFN-gamma was determined after specific stimulation of these TLC, using autologous monocytes as APC.
314 1972164 With respect to the production of IL-4 and IFN-gamma, clearly distinct profiles were observed.
315 1972164 All Dp-specific TLC from both atopic donors produced IL-4 but not IFN-gamma, whereas the Dp-specific TLC from NAD, as well as the tetanus toxoid- and C. albicans-specific TLC from AD1, all produced IFN-gamma but not or small quantities of IL-4.
316 1972164 The functional consequence of these restricted lymphokine profiles was stressed by the observation that, whereas Dp-specific TLC from AD1 and AD2 supported in vitro IgE production, this support could be abrogated by a Dp-specific TLC from NAD.
317 1972164 The present results suggest that CD4+ T lymphocytes that produce IL-4, but not IFN-gamma, occur in high frequencies in the allergen-specific T cell repertoires of atopic donors, which may have important implications for the pathomechanism of atopic disease.
318 1987026 Results are discussed in terms of the role of PGE2 as it impinges on immune functions involving macrophage activation (IL-1 production) and T lymphocyte activation (IL-2 production).
319 1988163 Recombinant diphtheria toxin-related interleukin-2 fusion protein (DAB486IL-2) is specifically cytotoxic for cells bearing the high-affinity IL-2 receptor (p55/75).
320 1988163 The induction of the p55 (Tac) subunit of the IL-2R was demonstrable by two-color flow cytometry on a small percentage (5%) of B cells and on a higher percentage (10%) of non-B cells 3 days after exposure to TT-coupled Sepharose.
321 1997399 T cells induced by p146-171 and p467-171 or a mixture of these two peptides were mainly CD4+ and produced interleukin (IL-2) and interferon-gamma (IFN-gamma) but not IL-4 upon antigen stimulation in vitro.

335 2104221 In an attempt to monitor the immunological effects of this therapy, we analyzed the urine of patients following the sixth intravessical instillation, to show the presence of the monokines TNF and IL 1 and the lymphokine IL 2.
336 2104221 Within 24 hours following the instillation, all (n = 10) patients exhibited a strong increase in urinary cytokine secretion, which was significantly different from the control group (n = 10), with respect to TNF L929 biological assay (P less than 0.01), TNF sandwich-ELISA (P less than 0.01), IL 2 CTL 6 biological assay (P less than 0.05), IL 2 sandwich-ELISA (P less than 0.005), and IL 1 sandwich-ELISA (P less than 0.05), but not to the IL 1 fibroblast biological assay.

343 2108928 After immunization with killed-bacterial vaccine, T-cell responsiveness to interleukin 2 (IL-2) never developed but a lower level of responsiveness to IL-1 appeared later than with T cells from mice immunized with viable bacteria.
344 2123823 Mycobacterium-specific T cells from both BALB/c and B10.D2 mice produced interleukin-2 and no interleukin-4.
345 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.
346 2125574 Staphylococcal enterotoxin A induced interferon (IFN)-gamma production in spleen cells from BCG-immunized mice: the IFN production is dependent on leukotriene C4 but not dependent on interleukin 2.
347 2125574 In analyzing the phenomenon in vitro, we showed that SEA induced IFN-gamma in the supernatant of the spleen cell culture from BCG immunized B6 mice and that leukotriene C4 (LTC4) from BCG activated macrophages in the spleen was involved in the IFN production from Ly 1+ T cells.
348 2125574 On the other hand, interleukin-2 (IL-2) has reported to play an important role in the regulation of synthesis of IFN-gamma by T cells.
349 2125574 In the present study, we examined whether IL-2 is involved in SEA-induced IFN production.

387 2168340 Mice immunized orally with the nucleoprotein-expressing bacteria mounted a strong anti-viral antibody response and spleen cells from such mice proliferated specifically to virus challenge in vitro, producing interferon-gamma (IFN-gamma) and interleukin-2 (IL-2).
388 2181071 We examined the kinetics of the in vitro proliferative response to PHA and IL-2 and found that while the response of lymphocytes primed in vivo with IL-2 to PHA was depressed at all times during the 2 week in vitro exposure, the response to IL-2 peaked earlier and higher than did the response to IL-2 by lymphocytes obtained prior to IL-2 therapy.

411 2493675 We made use of a recombinant vaccinia virus encoding and expressing the murine IL-2 gene and recombinant IL-2 to test the role of IL-2 in the expression of major histocompatibility complex (MHC) class I determined immune response (Ir) gene defects in the response to vaccinia virus.
412 2509329 (ii) Interleukin-2 (IL-2), interferon-gamma (IFN-gamma) and N-acetyl muramyl-L-threonyl-D-isoglutamine ([Thr1]MDP), but not its liposoluble 6-O-stearoyl derivative (6-O-S-[Thr1]MDP), co-entrapped with the toxoid at appropriate phospholipid to toxoid ratios, generally reduced primary response to levels below those achieved with liposomes containing the antigen alone.
413 2509329 Further, responses obtained with 6-O-S[Thr1]MDP coentrapped with the toxoid or separately entrapped were higher than those seen with [Thr1]MDP in similar formulations.
414 2525677 The values were related to age, duration of hemodialysis, body weight, creatinine, urea nitrogen, serum concentrations of beta 2-microglobulin and soluble interleukin-2 receptor (IL-2R).
415 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.
416 2526739 With some variations among donors, antigens clearly induced measurable levels of IFN-gamma, GM-CSF and IL 2 mRNA.

419 2527276 The suppressed PHA blastogenic response on day 7 was not enhanced by the addition of interleukin-2 or indomethacin even though an increase in cell number expressing CD25 was observed.
420 2527276 The removal of CD4+ or CD8+ cells enhanced the PHA response but only on days 2 or 4 and not at other sampling times, which suggests that the suppression is mediated by CD4+ or CD8+ cells.
421 2563003 Systemic production of antibodies against hepatitis B surface antigen was initiated in those immunodeficient patients whose cellular interleukin-2 receptor levels were found to be enhanced.
422 2574188 The earliest TH defect is the loss of responses to FLU and TET, indicating a selective defect in CD4+ MHC self-restricted TH function.
423 2574188 The later loss of ALLO and PHA IL-2 responses suggests more severe TH dysfunction involving both CD4+ and CD8+ T cells.
424 2659274 It is also possible to contemplate using the avirulent Salmonella to target expression of various modulators of the immune system such as interleukin-2 and interferon-gamma to the GALT and thus further enhance the immune response.
425 2810255 The addition of exogenous interleukin 2 augmented responses to the tetanus toxoid, however, no such enhancement with type II collagen was noted in our patients.
426 2826591 We determined that recombinant interleukin 2 (rIL-2) administered in conjunction with herpes simplex virus (HSV) crude extract or recombinant glycoprotein D subunit vaccine enhances the protective effect of either antigen preparation against HSV type 2 genital infection in guinea pigs.
427 2894392 Human memory T lymphocytes express increased levels of three cell adhesion molecules (LFA-3, CD2, and LFA-1) and three other molecules (UCHL1, CDw29, and Pgp-1) and have enhanced IFN-gamma production.
428 2894392 Studies of cell-surface molecules involved in human T cell interaction reveal that differential expression of each of three adhesion molecules (LFA-3, CD2, and LFA-1) subdivides human peripheral blood T cells into major subpopulations.
429 2894392 Systematic analysis of the relationship between expression of these and other markers of T cell subsets demonstrates a single major subset of human peripheral blood T lymphocytes distinguished by enhanced expression of LFA-3, CD2, LFA-1, and three other markers (CDw29 [4B4], UCHL1, and Pgp-1).
430 2894392 Large differences in relative expression are observed for UCHL1 (29-fold) and LFA-3 (greater than 8-fold), and smaller differences (2- to 4-fold) are seen for CDw29, CD2, LFA-1, and Pgp-1.
431 2894392 Bimodal distribution of LFA-3 is found on both CD4+ cells and on CD8+ cells as well as on B lymphocytes (CD19+).
432 2894392 Neonatal T cells (CD3+) are comprised almost exclusively of the subset expressing low LFA-3, CD2, LFA-1, CDw29, and UCHL1.
433 2894392 Furthermore, the LFA-3+ subset made greater than fivefold more IFN-gamma than the LFA-3- subset in response to PHA, despite the fact that both subsets made equivalent amounts of IL-2.
434 2894392 This phenotypic and functional analysis of resting and activated newborn and adult T cells indicates that human memory T cells express enhanced levels of LFA-3, CD2, LFA-1, UCHL1, CDw29, and Pgp-1; we speculate that the increase in expression of T cell adhesion molecules LFA-3, CD2, and LFA-1 on memory cells is functionally important in their enhanced responsiveness.

436 2904885 Limiting dilution culture of the activated T lymphoblasts in interleukin 2-containing medium generated stable CD3+CD4+CD8- T cell clones.
437 2932383 Since previous work had indicated that suppression involved the inhibition of the production of interleukin-2 (IL-2), the effects of BCG on interleukin-1 (IL-1), a monokine required for IL-2 production, were investigated.
438 2939948 This was concomitant with restoration and maintenance of normal interleukin-2 (IL-2) and interleukin-3 (IL-3) levels and prevention of suppressor cell development in mice injected with both tumor cells and vaccine.
439 2939948 Our finding of C. parvum-induced maintenance of IL-2 and IL-3 levels and apparent lack of suppressor cell formation lends support to the idea of local C. parvum antitumor action possibly being mediated by CTL arising via the interleukin cascade.

449 3070530 (table; see text) These include two major areas of focus at the present time: (1) the use of IL-2 +/- LAK in combination with a variety of agents which have been shown to be synergistic with it, including other biological response modifiers (such as interferons), agents which may act both as interferon inducers as well as by other mechanisms (poly-IC:LC and flavone-8-acetic acid), and chemotherapeutic agents (especially cyclophosphamide, doxorubicin and agents which have some activity against the disease being treated such as DTIC for melanoma), and (2) various approaches aimed at inducing and expanding tumor-specific immune cells which appear to have greater antitumor activity than LAK cells and which may be major contributors to the antitumor efficacy of IL-2 therapy.

459 3097138 Although splenocytes from immunized P mice demonstrated deficiencies in production of macrophage-activating lymphokine(s) in response to either antigenic or mitogenic stimulation, other aspects of T lymphocyte responsiveness including blastogenesis, production of interleukin 2, interleukin 3 and macrophage chemotactic factor, as well as helper cell function for secondary plaque-forming cell response to a T-dependent antigen and allospecific cytolytic T cell reactivity, appeared to be comparable with those of C57BL/6 mice, a strain that is protected by vaccination against S. mansoni.
460 3119733 Is recombinant interleukin-2 the best way to deliver interferon-gamma in human disease?

491 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.
492 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.

495 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.
496 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.
497 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.

500 7499443 Induction of antitumor immunity and treatment of preestablished tumor by interleukin-6-gene-transfected melanoma cells combined with low-dose interleukin-2.
501 7499443 These data demonstrated that IL-6-gene-transfected cancer vaccine has a potent antitumor effect via efficient induction of antitumor immunity, and a better therapeutic effect could be achieved when the vaccine is combined with low-dose IL-2 as adjuvant.

504 7504709 In this study we increase the evidence that schistosome TPI is a potential vaccine Ag by showing that it also a potent inducer of IL-2 and IFN-gamma production (Th1 responses), driving production of these cytokines in the same cell populations of infected animals that have high Th2 responses directed at other parasite egg Ag.
505 7504709 Finally we showed that both the full-length TPI molecule and the final version of the MAP were immunogenic to T cells in naive animals and induced cross-recognition in the form of IL-2 and IFN-gamma production.

508 7513036 MBV's effect on interleukin-2 (IL-2) production, plasma interferon (IFN) and tumor necrosis factor (TNF) levels was monitored.
509 7513036 In general there was little correlation between IL-2 and IFN levels or with the response to therapy.
510 7513036 MBV's effect on interleukin-2 (IL-2) production, plasma interferon (IFN) and tumor necrosis factor (TNF) levels was monitored.
511 7513036 In general there was little correlation between IL-2 and IFN levels or with the response to therapy.
512 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.
513 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.
514 7520417 OspA and OspB also induced the production of high levels (40 to 150 ng/ml) of IFN-gamma in cultures of macrophages incubated with interleukin-2 (IL-2)-elicited cells from normal (T and NK cells) and scid (NK cells) mice but not in macrophages or IL-2-elicited cells cultured individually.
515 7520417 Reverse transcriptase rapid PCR demonstrated that OspA and sonicated B. burgdorferi stimulated production of several inflammatory cytokines in macrophage cultures, including IL-1, IL-6, IL-12, IFN-beta, and tumor necrosis factor alpha.
516 7520417 As tumor necrosis factor alpha, IFN-beta, and IL-12 are potent activators of IFN-gamma production by T and NK cells, their presence in these cocultures could be responsible for the IFN-gamma production.
517 7525715 Relative efficacy of IL-2, IL-4, and granulocyte-macrophage colony-stimulating factor.
518 7525715 Here, we demonstrate that fusion proteins with IL-2 or IL-4 can also be highly immunogenic.
519 7525715 Furthermore, the Id-IL-2 fusion protein induced high titers of IgG2a and IgG3 anti-Id Abs, whereas the Id-IL-4 and Id-GM-CSF fusion proteins did not.

526 7525727 A similar, although less dramatic, increase in two other macrophage-activating cytokines, TNF-alpha and IL-2, also was observed.
527 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.
528 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.
529 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.
530 7525727 A similar, although less dramatic, increase in two other macrophage-activating cytokines, TNF-alpha and IL-2, also was observed.
531 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.

533 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.
534 7533857 To increase the inherently weak immunogenicity of synthetic peptide vaccines, we used recombinant DNA techniques to generate chimeras between immunogenic determinants of human immunodeficiency virus type 1 (HIV-1) gp120 and antibody Fab fragments reactive with surface structures displayed specifically on human antigen-presenting cells (APCs), including surface immunoglobulin D (sIgD) and class II major histocompatibility complex (MHC) molecules.
535 7533857 Furthermore, such recombinant immunotargeted HIV-1 peptide antigens demonstrated improved immunogenicity over equivalent nonimmunotargeted control antigens, as shown by their ability to stimulate interleukin-2 production by CD4+ T-helper cells from human donors exposed to HIV-1 antigens.
536 7533857 These data suggest that immunotargeting of recombinant peptide antigens via the attached Fab fragments facilitates uptake by human APCs with subsequent access to the MHC class II processing pathway, thereby validating the immunotargeting concept for such recombinant subunit vaccines in an in vitro human system.
537 7537831 Japanese national references of IL-2 and TNF alpha were calibrated by collaboration with related companies and NIH Japan and the concluded results are obtained as follows.
538 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.
539 7543537 Although both C57BL/10 (B10) and BALB/c mice bear the susceptible phenotype of innate resistance, Calmette-Guérin bacillus (BCG) vaccination generated efficient API in B10 but not in BALB/c mice.
540 7543537 Employing a specific nitric oxide (NO) synthase inhibitor, we revealed that NO production plays a pivotal role in the API of B10 mice.
541 7543537 Furthermore, IFN-gamma, a potent inducer of iNOS, and mRNAs for IL-12 (p40); an inducer of IFN-gamma and IL-2 were also vigorously expressed in the spleen of B10 mice compared with that of BALB/c mice.
542 7543537 We found that multiple functions of macrophages, which include capacities to express IL-12 (p40) mRNA in response to BCG and to express mRNAs for iNOS and IL-12 (p40) in response to IFN-gamma, were impaired in BALB/c mice as compared with B10 mice.
543 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.
544 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.
545 7553882 Most cytokines stimulated nonspecific killers, but IL-2 and IL-3 stimulated primary CTL.
546 7553882 While IFN-gamma alone did not generate primary CTL, coexpression of IFN-gamma with IL-2 resulted in CTL generation.

553 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.
554 7554398 DC and B cells pulsed with iscoms stimulated most efficiently the secretion of IL-2 and IFN-gamma.
555 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.
556 7554398 DC and B cells pulsed with iscoms stimulated most efficiently the secretion of IL-2 and IFN-gamma.
557 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.
558 7585534 We have analyzed and compared in detail the malignant phenotypes of, the immune mechanisms induced by, and the immunotherapeutic potentials of B16-F10.9 melanoma cells manipulated by gene transfer to express syngeneic H-2Kb molecules or to secrete the cytokines interleukin 2 (IL-2) or IL-6.
559 7585534 Local tumor growth in the footpad of transduced cells is mainly retarded by expression of H-2Kb and IL-2 genes and less by expression of IL-6.
560 7585534 After i.v. inoculation, mice given injections of F10.9-Kb expressors did not develop experimental lung metastases; mice given injections of F10.9-IL-6 secretors developed reduced metastatic loads; whereas mice given injections of F10.9-IL-2 secretors developed high loads of lung metastases.
561 7585534 On the basis of injections into nude mice, in vivo depletions of CD4+, CD8+, and NK1.1+ cells, and in vitro CTL and natural killer (NK) assays, we show that all F10.9-modified cells induce CD8+ tumor-specific CTL activity and that F10.9-IL-2 secretors also induce nonspecific NK/lymphokine-activated killer cell activity.

574 7589080 CD8+ T cells did not proliferate in vitro even in the presence of the appropriate peptide epitope and exogenous interleukin (IL)-2.
575 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.

577 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.
578 7590827 Levels can be increased dramatically by coinjection of DNA plasmids encoding either IL-2 or GM-CSF, and specific proliferative anti-idiotypic T cells are induced.
579 7594484 In addition to the Ag-specific production of IL-2 by CD4+ peritoneal cells that was elicited, several other correlates of protective responses were noted, including dramatic induction of CD3+ and alpha beta TCR+ cell populations in the peritoneal cavity and increased expression of class II MHC and production of IL-12 (upon in vitro restimulation) by peritoneal macrophages.
580 7614735 In vitro T-cell responses were measured by proliferation and IL2, IFN-gamma, and IL4 release.
581 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.
582 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.
583 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.
584 7620165 In contrast, in normal individuals addition of aAC, which predominantly consisted of monocytes, resulted in a significant increase of IFN-gamma and a reduction of IL-4 secretion.
585 7620165 On the other hand, purified monocytes from CLL patients and controls both induced IFN-gamma production and inhibited IL-4 secretion.

591 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.
592 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.
593 7627623 Other therapies include CTL stimulation, via the macrophage route, by erythrocytes, into which MHC binding HIV-CTL epitope polypeptide fragments have been inserted; passive immunization, virion-trapping by CD4 analogs or CD4 expressing erythrocytes; and combination therapies with AZT, IL-2.
594 7635511 The activated T cells secreted interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) which was abrogated by treatment with anti-CD4 but not with anti-CD8 antibody.
595 7639014 All three forms of immunization appeared to stimulate T-cell responses as assessed by in vitro antigen-specific spleen cell proliferation and IL-2 secretion indicative of a Th1 type response, however, cells from i.p. immunized mice only secreted low levels of IL-5.
596 7648281 Predominantly CD8+ T-cell lines generated from PBMC by nonspecific stimulation with PHA and IL-2 were screened after three to four weeks of culture for cytolytic activity against autologous targets infected with vaccinia vectors encoding envLAI, RT, gag, and lacZ control.
597 7650382 In wild-type mice administration of recombinant IFN-gamma but not IL-2 mimicked the immune-stimulating activity of IL-12; it is therefore likely that the IL-12 adjuvant activity is largely mediated by physiologic IFN-gamma.
598 7658307 Resolution of lesions and subsequent protection against ringworm is primarily associated with the development of a cell-mediated immune (CMI) response, in which stimulation of Type-1 lymphocytes and cytokines such as interleukin-2 (IL-2), IL-12 and interferon gamma are significant.
599 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.
600 7664800 Systemic immunization induces protective CD4+ and CD8+ T cell-mediated immune responses in murine Listeria monocytogenes meningoencephalitis.
601 7664800 The immune mechanisms underlying immunization-induced protection of mice from lethal central nervous system (CNS) listeriosis were evaluated by immunohistochemistry, flow cytometry of leukocytes isolated from the brain, reverse transcription-polymerase chain reaction analysis of intracerebral (i.c.) tumor-necrosis factor-alpha, interferon-gamma, interleukin (IL)-2, IL-1 beta, IL-10, granulocyte/macrophage colony-stimulating factor, and inducible nitric oxide synthase mRNA expression, and T cell depletion experiments.
602 7664800 The data demonstrate that active immunization of mice prior to an i.c. infection with Listeria monocytogenes prevents the development of a fatal necrotizing encephalitis and accelerates the recruitment of an increased number of alpha beta T cell receptor (TcR)+ CD4+ and CD8+ T cells, gamma delta TcR+ T cells, B cells, granulocytes and macrophages to the brain compared to non-immunized animals.
603 7664800 The protective effects of immunization were completely abolished by depletion of CD4+, CD8+, or both T cell subsets.
604 7664800 The severity of disease was only slightly different between CD4+, CD8+ and CD4+/CD8+ T cell depleted mice, indicating that both subsets of T cells are required for an effective i.c. immune response to L. monocytogenes.
605 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).
606 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.
607 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.

613 7687626 Taken together, we have shown that human T cell clones immortalized with H. saimiri express functional CD3, CD4, and IL-2R.
614 7688563 The proliferating T cells produce levels of IL-2 and IFN-gamma, that indicate antigen-specific T helper type 1 cells are present in significant numbers.

620 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.
621 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.
622 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.

627 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.
628 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.
629 7702748 IL-4 and IL-10, together with antibodies, are important for parasite clearance in later phases of infection.
630 7702748 In contrast to the CD4+ T cells, the role of CD8+ T cells in blood stage infection appears to be limited, but suppression of some CD4+ activities has been reported for both experimental and human malaria.
631 7703440 Studies employing rodent tumor models with little or no intrinsic immunogenicity have shown that genitically modified tumor cell preparations consisting of irradiated tumor cells transduced with and expressing cytokines such as IL-2, IL-6, IFN-gamma or GM-CSF were capable of inducing the regression of a preexisting tumor burden and cure animals from their disease.
632 7719917 In ex vivo CD4+ subsets, this interleukin-2 response was paralleled by a > 10% increase in the proportion of cells expressing the CD45RO+ phenotype following vaccination (p < 0.0001).
633 7722322 Exposure to supernatant fluids (SNs) from Ag stimulated spleen cells of i.d., but not i.v. or i.m., immunized mice activated inflammatory M phi for in vitro killing of schistosome larvae, through a mechanism dependent on both IFN gamma and TNF-alpha.
634 7722322 No evidence was observed for the preferential induction of the M phi activating Th1 cytokines IFN-gamma and IL-2 in i.d. immunized mice, nor did spleen cells from nonprotected animals produce higher levels of the Th2 associated cytokines IL-4 and IL-10, which are known to prevent M phi activation.

639 7750991 Spleen and lymph node cells from the immunized mice produced significant amounts of interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) but no detectable IL-4 when cultured with L. major antigens in vitro.
640 7761694 The purified T cells proliferated very weakly in response to Salmonella in the absence of interferon-gamma and interleukin 2/4 production.
641 7776443 Furthermore, the cleavage postulate that, in vivo, LAK cells activated by IL-2 produced by BCG activated CD4+ cells may induce bladder cancer cells to undergo apoptosis.
642 7777545 Although both CD4+ and CD8+ T cells are clearly required to generate long-lasting anti-tumor immunity induced by s.c. vaccination with interleukin 2 (IL-2)-transfected, irradiated M-3 clone murine melanoma cells, some controversy continues about the site and mode of T-cell activation in this system.
643 7782155 Thus, although both liposomal antigens are capable of inducing potent humoral responses characterized by increased production of IgM and IgG2a, covalently linked antigen stimulates a quasi-polyclonal blastogenic response accompanied by the simultaneous secretion of IL-2 and IFN gamma, while encapsulated antigen which is less blastogenic mainly induces IL-2 secretion.

667 7810061 Natural killer cells were not the major cell type involved, but CD4+ lymphocytes themselves seemed to respond to IL-2 irrespective of the presence of antigen.
668 7855624 We also are studying two approaches for stimulating T-cells in tumor-conditioned hosts. (1) We have shown that IL-7 has potent costimulatory effects on T cells as well as some antitumor effects. (2) We are developing a comprehensive vaccine-type gene therapy approach whereby T cells and antigen-presenting dendritic cells are recruited through the use of antigen, chemokines and GM-CSF.
669 7855624 Studies are in progress to determine whether the activity of these recruited cells can then be potentiated by Renca or fibroblast transfectants that express T-cell costimulatory cytokines (IL-2, IL-4, IL-7, or IL-12).
670 7868269 We have previously demonstrated that spleen cells from Brucella-infected mice produced gamma interferon (IFN-gamma) and interleukin-2 (IL-2) in response to Brucella antigens in vitro, while spleen cells from mice immunized with soluble Brucella proteins (SBP) produced substantial amounts of IL-2 but no detectable amount of IFN-gamma.
671 7868269 In this study, we further analyzed the response of T cells from Brucella-infected mice and SBP-immunized mice and demonstrated that CD4(+)-enriched cells from SBP-immunized mice also produced significant amounts of IL-4, which was not detected in bulk cultures of spleen cells from infected mice.
672 7868269 Limiting dilution analysis showed that infection resulted in a higher precursor frequency of IFN-gamma-producing CD4+ T cells and a lower precursor frequency of IL-4-producing CD4+ T cells, while immunization with SBP resulted in a higher precursor frequency of IL-4-producing cells and a very low frequency of IFN-gamma-producing cells.
673 7868269 Furthermore, IFN-gamma-producing CD4+ T cells from infected donor mice were capable of mediating resistance against challenge infection in recipient mice, but IL-4-producing CD4+ T cells from immunized mice failed to do so.

682 7881637 Therapeutic effect of a vaccinia colon oncolysate prepared with interleukin-2 (IL-2) gene-encoded vaccinia virus (IL-2VCO) in combination with recombinant interferon-alpha (IFN-alpha) was studied in a syngeneic murine CC-36 colon hepatic metastasis model.
683 7881637 The only treatment that produced a survival rate similar to the survival rate of IL-2VCO+IFN-alpha was VCO+IL-2 + IFN-alpha (survival rate was 67%).
684 7881637 The mechanism of the induction of antitumor response by the VCO+IL-2+IFN-alpha treatment was analyzed by measuring the direct cytotoxic activity of IFN-alpha on CC-36 tumor cells and by measuring the induction of cytolytic T-cell activity against CC-36 tumor cells.
685 7881637 It was found that the survival rate was affected in mice depleted with CD8-positive T cells and treated with IL-2VCO+IFN-alpha when compared to control mice which had no T-cell depletion and were treated with IL-2VCO+IFN-alpha.
686 7881637 This study suggests that the addition of IFN-alpha along with IL-2VCO increased the survival rate of mice having CC-36 hepatic metastases through the induction of CD8-positive T cells.

710 7897222 Using a receptor-mediated, adenovirus-augmented gene delivery system (transferrinfection) we have shown that, upon transfection with an IL-2 gene construct, MHC class I+/class II- murine M-3 cells lose their tumorigenicity in both athymic and euthymic mice.
711 7897222 Transfer of either CD4+ or CD8+ T cells led to only partial protection against challenge with wild-type M-3 cells.
712 7897222 Our further observations that T cell-enriched, but not T cell-depleted splenocytes of immunized animals are capable of tumor-specific lytic activity and that this activity resides in the CD8+ cell population are compatible with the assumption that MHC class I-restricted T cell cytotoxicity is a biologically relevant effector mechanism in this model.
713 7901150 This is recognized by immune CD4 T cells which function as essential helper cells in the generation of the CD8 CTL response.
714 7901150 The existence of two types of cognate T cell responses in a syngeneic anti-tumour response was directly proved by the establishment of two types of tumour specific T cell lines which required as co-stimulator either MHC class II positive APC or IL-2.
715 7901150 The generation of the tumour specific CTL response could be blocked by monoclonal antibodies against all the molecules involved in the cognate interactions (i.e. class I MHC, CD8, class II MHC, CD4 and TCR) but not by anti-CD2 or anti-IgG.
716 7901150 The strict requirement for helper cells and APC could be bypassed by the addition of recombinant IL-2 but optimal triggering of CD8 CTL-precursor required viable tumour stimulator cells.
717 7901150 This well characterized in vitro assay may be useful (i) for monitoring the immune status of CD4 and CD8 immune T cells separately, for instance of tumour bearing and/or treated animals and (ii) for the development and testing of potent tumour cell vaccines with T cell stimulatory and/or co-stimulatory activities.

723 7902215 In vitro synthesis of IL-4 by human CD4+ T cells requires repeated antigenic stimulation.
724 7902215 Although Th2 helper cell clones produce IL-4 and IL-5, CD4+ T cells taken fresh from lymphoid organs of mice produce IL-2 and some IFN-gamma, but not IL-4 or IL-5.
725 7902215 The exact parameters that enhance the synthesis of IL-4, IL-5, and particularly IL-10 from resting antigen-specific CD4+ T cells is not yet clear.

727 7902215 We demonstrated that in vitro stimulation of human peripheral blood lymphocytes with antigen (tetanus toxoid or a viral antigen, Varicella zoster) for several days resulted in the production of IL-2 and IFN-gamma, but little or no IL-4 or IL-5.
728 7902215 Furthermore, we observed that human CD4+ T cells from either allergic or nonallergic individuals failed to produce significant quantities of IL-4, IL-5, or IL-10 even after several rounds of stimulation with soluble protein (nonallergen) antigens such as tetanus toxoid or Var. z.
729 7902215 In addition, substantial quantities of IL-4, IL-5, and IL-10 were produced by CD4+ T cells from allergic subjects in the absence of exogenous IL-4, but only after two stimulations in vitro with allergens such as rye grass pollen or dust mite allergen.
730 7902215 These results indicate that the development of IL-4 and IL-5 synthesis occurs in peripheral blood CD4+ T cells in a stepwise fashion, first with the production of IL-2 and IFN-gamma, and later with the production of IL-4 and IL-5.

747 7910675 We have found that the cause of the blunted response to HBV vaccination is multifactorial and seems to be associated with the following: (1) A reduced number of TCR/CD3 antigen receptor complexes on freshly isolated uraemic CD4 T cells, especially in non-responders. (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.
748 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.
749 7923243 The median fraction of cells that were T cells in post-vaccine tumors was 41%, as compared with 9% in pre-treatment tumors, and those T cells were predominantly CD8+ (mean CD8/CD4 ratio = 5.0).
750 7923243 These changes were not accompanied by increased cell-surface expression of interleukin-2 (IL-2) receptors, either CD25 or p75, which were expressed by 1%-2% and 12% of tumor-infiltrating lymphocytes (TIL), respectively.
751 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.
752 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.
753 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.
754 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.
755 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.
756 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.

760 7954527 Tumor necrosis factor alpha (TNF alpha) and interleukin-1 beta (IL-1 beta) were detected at markedly high levels at 24 h, and interferon gamma (IFN gamma) was detected at 120 h.
761 7954527 IL-2 and macrophage-colony-stimulating factor were not detected.
762 7963714 PBMC from 22 subjects previously infected with RSV usually had RSV-specific increases in TH1 cytokine-specific mRNA (interferon-gamma [IFN-gamma] mRNA, 20; interleukin [IL]-2 mRNA, 12; IL-5 mRNA, 6; and IL-4 mRNA, 0).
763 7963714 PBMC from RSV antibody-negative children had no RSV-specific increases in IFN-gamma, IL-2, or IL-4 mRNA; 1 of 7 had an increase in IL-5 mRNA.
764 7963714 PBMC from 22 subjects previously infected with RSV usually had RSV-specific increases in TH1 cytokine-specific mRNA (interferon-gamma [IFN-gamma] mRNA, 20; interleukin [IL]-2 mRNA, 12; IL-5 mRNA, 6; and IL-4 mRNA, 0).
765 7963714 PBMC from RSV antibody-negative children had no RSV-specific increases in IFN-gamma, IL-2, or IL-4 mRNA; 1 of 7 had an increase in IL-5 mRNA.
766 7963713 Mice transgenic for beta 2-microglobulin deletion (beta 2M-/-) were immunized intranasally with either a recombinant vaccinia virus that expressed both nucleoprotein and interleukin-2 or by infection with H3N2 influenza virus; 3-4 weeks later they were challenged with H1N1 influenza virus.
767 7975832 The CD4+ T cells isolated from PP and SP of mice orally immunized with CT were stimulated in vitro with CT-B-coated latex microspheres for 1-6 days, and the induction of IL-2 and interferon gamma (IFN-gamma) (Th1-type) or IL-4 and IL-5 (Th2-type) producing SFCs were analysed by a cytokine-specific ELISPOT and cytokine-specific mRNA was detected by reverse transcriptase (RT)-PCR assays.
768 7983727 Local expression of tumor necrosis factor alpha and interleukin-2 correlates with protection against corneal scarring after ocular challenge of vaccinated mice with herpes simplex virus type 1.
769 7983727 Infiltration into the cornea of CD4+ T cells, CD8+ T cells, macrophages, and cells containing various lymphokines was monitored on days 0, 1, 3, 7, and 10 postchallenge by immunocytochemistry of corneal sections.
770 7983727 In response to the ocular challenge, these mice developed high local levels of infiltrating CD4+ T cells and cells containing interleukin-2 (IL-2), IL-4, IL-6, or tumor necrosis factor alpha (TNF-alpha).
771 7983727 In contrast, only low levels of infiltrating CD8+ T cells were found, and gamma interferon (IFN-gamma)-containing cells were not present until day 10. gE-vaccinated mice developed neutralizing antibody titers in serum almost as high as those of the KOS-vaccinated mice (> 1:320).
772 7983727 Compared with KOS-vaccinated mice, the gE-vaccinated mice had a similar pattern of IFN-gamma, but a delay in the appearance of CD4+ T cells, CD8+ T cells, and IL-4-, IL-6-, and TNF-alpha-containing cells.

778 7990015 Gingival cell IL-2 and IL-4 in early-onset periodontitis.
779 7990015 The purpose of this study was to compare, using cell blot analysis, the association of gingival tissue mononuclear cells (GTMC) isolated from lesions displaying histories of early-onset periodontitis (EOP; typically B-lymphocyte dominated) and gingivitis (typically T-lymphocyte dominated) with the B-cell stimulating cytokine, interleukin (IL)-4, and the T-cell stimulating cytokine, IL-2.
780 7990015 Membranes were treated with monoclonal anti-IL-2 or anti-IL-4, followed by a biotin-conjugated second layer, streptavidin-alkaline phosphatase and nitro blue tetrazolium/5-bromo-4-chloro-indolyl-phosphate (NBT/BCIP) color development.

787 7997190 Our results show that all T cells reactive with bacteria produce interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha), but no interleukin (IL)-4 and no or very little IL-2 and IL-10 and, thus, belong to the Th1 subset, while T cells reactive with tetanus toxoid or Anisakis belong to the Th0 subset with production of IFN-gamma, IL-2, IL-4, IL-10 and TNF-alpha.
788 8012975 In this study we have compared the effectiveness of several cytokines and found that while IL-1 alpha, IL-1 beta, and gamma-interferon were only weakly effective in the therapeutic vaccination protocol, granulocyte-macrophage colony-stimulating factor was almost as effective as but not superior to IL-2, as reported previously for another tumor model system.
789 8013962 High responders displayed a typical Th1-like profile since their PBMC produced interleukin-2 (IL-2) and gamma-interferon (IFN gamma) and no detectable IL-4 or IL-5 upon stimulation with HBsAg.

791 8035532 In the present studies, we sought to determine the relative contributions of gamma interferon (IFN-gamma), IL-2, IL-4, and IL-10 to the lymphocytic infiltration into the lungs observed following RSV challenge of mice previously immunized with FI-RSV.
792 8035532 Mice previously immunized with FI-RSV or infected with RSV were depleted of IFN-gamma, IL-2, IL-4, or IL-10 immediately before RSV challenge, and the magnitude of inflammatory cell infiltration around bronchioles and pulmonary blood vessels was quantified.
793 8035532 Simultaneous depletion of both IL-4 and IL-10 completely abrogated pulmonary histopathology in FI-RSV-immunized mice.
794 8035532 Depletion of IFN-gamma, IL-2, or both together had no effect on the observed histopathology.
795 8035532 These data indicate that FI-RSV immunization primes for a Th2-, IL-4-, and IL-10-dependent inflammatory response to subsequent RSV infection.

808 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.
809 8056039 Cells producing IL-2, IFN-gamma and particularly TNF-beta dominated this in vitro response.
810 8056039 The addition of IL-2 to the cultures caused a fourfold increase and a kinetics shift in the production of TNF-beta, which peaked already at 24 h.
811 8056039 Exogenously added IL-2 also caused a five- to tenfold increase in the number of IL-2 and IFN-gamma producers but no apparent change in the kinetics of intracellular lymphokine appearance.

828 8087858 House dust mite-responsive human T cells require both interleukin 2 (IL2) and interleukin 4 for optimal proliferation, whereas IL2 alone is sufficient for proliferation of tetanus toxoid-responsive T cells.
829 8087858 Peripheral blood lymphocytes were cultured with either house dust mite (HDM) or tetanus toxoid under limiting dilution conditions with interleukin 2 (IL2) alone or IL2+IL4.
830 8087858 The combination of IL2+IL4 resulted in the highest proportion of responding HDM-specific T cells.
831 8087858 These HDM and Der pI responsive cells were found to be CD4+CD8-.
832 8087858 House dust mite-responsive human T cells require both interleukin 2 (IL2) and interleukin 4 for optimal proliferation, whereas IL2 alone is sufficient for proliferation of tetanus toxoid-responsive T cells.

840 8093707 Elevated serum IgG1, IgA, and IgE responses, weak or absent footpad reactions, sustained production in vitro of Th2 (IL-4 and IL-10) but not Th1 (IL-2 and IFN-gamma) cytokines by CD4+ cells, and eosinophilia were all detected in DBA/2 mice after infection with the attenuated vaccine.
841 8094096 We also detected cytokines in the skin lesions: (1) interleukin-1 alpha and tumor necrosis factor alpha were strongly positive in all patients with acute Kawasaki disease, (2) interleukin-2 and interferon gamma were weakly or partially positive, (3) no cytokines were detected in the convalescent phase, and (4) the amounts of cytokines at the site of BCG vaccine inoculations were larger than those at the site of the polymorphous exanthem.
842 8094096 These findings suggest that CD4+ T lymphocytes and CD13+ macrophages are activated and interleukin-1 alpha and tumor necrosis factor alpha may be involved in the pathogenesis of the inflammation of acute Kawasaki disease.
843 8096062 Vaccination of mice with the protective F3G3 antigen of Toxoplasma gondii activates CD4+ but not CD8+ T cells and induces Toxoplasma specific IgG antibody.
844 8096062 CD4+ but not CD8+ T cells from immune animals proliferated and produced IL-2 upon restimulation with either Toxoplasma sonicate or F3G3-Ag in vitro.
845 8096062 Taken together the results show that the cytoplasmic F3G3-Ag of T. gondii induces CD4+ T helper cells, Toxoplasma specific IgG antibodies and long term protection against Toxoplasma infection, but does not induce detectable sensitization of the CD8+ T cell compartment.
846 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.
847 8097759 An HIV-1 envelope protein vaccine elicits a functionally complex human CD4+ T cell response that includes cytolytic T lymphocytes.
848 8097759 Antibody blocking and single cell cloning experiments demonstrated that the vaccine-induced cytolytic activity was mediated by CD4+, MHC class II-restricted T cells.
849 8097759 Longitudinal and cross-sectional studies revealed that the CD4+ CTL response was regulated in a complex manner and was not clearly correlated with MHC class II genotype, Ag dose, or number of immunizations.
850 8097759 Analysis of cytokine secretion by gp160-specific CD4+ T cell clones revealed Th0-, Th1-, and Th2-like patterns, with CD4+ CTL clones showing Th0- or T'1-like patterns.
851 8097759 Interestingly, many Th0- and Th1-like CTL clones produced very little IL-2, a finding that may explain the complicated regulation of this response.
852 8102828 Evidence for the role of human immunodeficiency virus type 1 Nef protein as a growth inhibitor to CD4+ T lymphocytes and for the blocking of the Nef function by anti-Nef antibodies.
853 8102828 To examine the functional role of HIV-1 Nef protein on the marked loss of CD4+ cells, Nef protein was expressed in and purified from Escherichia coli as a fusion protein with T7 phage gene10 product (Nef-gene10).
854 8102828 When peripheral blood mononuclear cells (PBMC) from healthy donors were cultivated in the presence of Nef-gene10 or the gene10 product as well as interleukin-2 (IL-2), it was found that the Nef-gene10, but not the gene10 product, induced a remarkable decline in the CD4/CD8 ratio and in the response to phytohaemagglutinin of PBMC as well as of nylon wool-passed purified T cells.
855 8102828 This suppression of the IL-2-dependent proliferation of CD4+ cells by Nef-gene10 seemed to be due to enhanced production of several lymphokines, especially of interferon-gamma.
856 8102828 Thus, Nef protein might be partly responsible for the selective depletion of CD4+ cells in HIV-1 infection.
857 8102828 Furthermore, the Nef-induced decline in the CD4/CD8 ratio was interrupted by anti-Nef antibodies, suggesting the possibility that a vaccine which resulted in the production of such functional Nef antibodies would be useful in the treatment of HIV-1-induced immunodysfunction.

864 8103069 Neither does injection of exogenous IL-2 compensate for the absence of CD4+ cells.
865 8103069 Mice immunized while depleted of CD4+ cells have normal numbers of CD8+ T cells infiltrating their livers.
866 8103069 Thus, it appears that although CD8+ cells have been activated in the absence of CD4+ cells, they cannot protect mice against malaria.
867 8103069 We conclude that a successful vaccine against the pre-erythrocytic stages of malaria must activate both CD4+ and CD8+ T cells.
868 8113740 Modulation of antiviral immune responses by exogenous cytokines: effects of tumour necrosis factor-alpha, interleukin-1 alpha, interleukin-2 and interferon-gamma on the immunogenicity of an inactivated rabies vaccine.
869 8113740 We investigated the effects of tumour necrosis factor-alpha (TNF-alpha), interleukin-1 alpha (IL-1 alpha), interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) on the immune response elicited by inactivated rabies virus vaccine in a mouse model.
870 8113740 A single dose of 1.3 ng TNF-alpha or IL-1 alpha, when injected shortly before vaccination, only marginally stimulated resistance to challenge infection (four- and seven-fold, respectively) without enhancing virus neutralizing antibody (VNAb) responses.
871 8113740 In contrast, a single injection of 10(3) units of IFN-gamma or five daily injections of 1.6 micrograms IL-2 increased vaccine dilutions protecting 50% of mice (PD50 values) 77- to 50-fold, respectively, with a concomitant enhancement of VNAb.
872 8113740 At a 1:10,000 dilution of a standard inactivated rabies vaccine preparation both IFN-gamma and IL-2 increased protective immunity without enhancing VNAb responses; in non-vaccinated animals this treatment had no effect on resistance to challenge.
873 8113740 Combined administration of IFN-gamma and IL-2 synergistically enhanced VNAb responses.

934 8252811 The present study analyses (i) the capacity of Q-Vax to induce T cell sensitization which leads to IFN-gamma responses on antigen stimulation, and (ii) the immunomodulatory, (down-regulatory) effects of the Phase I lipopolysaccharide (LPS) of the organism, which interacts with monocyte/macrophages to limit IL-2 production and production of IFN-gamma by sensitized T lymphocytes.
935 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.
936 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.

987 8270266 This paper describes the bacterial expression and purification of bioactive recombinant ovine interleukin-2 (rovIL-2), interleukin-1 alpha (rovIL-1 alpha) and tumour necrosis factor alpha.
988 8279092 A 24-h treatment of T24 cells with BCG resulted in a tenfold higher secretion of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF alpha) when compared with T24 cells treated with Escherichia coli, Streptococcus faecalis or a cell wall preparation of Nocardia rubra (N-CWS).
989 8279092 No secretion of IL-1 beta and IL-2 was detected.
990 8279092 Pre-exposing T24 cells to BCG for various periods of time indicated that a minimum exposure time of 0.5-1 h was required to upregulate IL-6 and TNF alpha production.
991 8279092 The amounts of these cytokines secreted in the presence of BCG-conditioned medium did not differ significantly from the constitutively secreted amounts, excluding an effect of products possibly secreted by BCG on the upregulation of IL-6 and TNF alpha.
992 8288319 IL-1 and tumour necrosis factor-alpha (TNF-alpha) remained undetectable in both instances.
993 8288319 Spleen cells taken at intervals after infection and cultured with brucella antigens produced high titres of IL-6, IL-1 and TNF-alpha.
994 8288319 Of the characteristically T-cell-derived lymphokines, interferon-gamma (IFN-gamma) production rose 2 weeks after infection, peaking at 6 weeks, while IL-2 was not detected until 6 weeks post-infection.
995 8288319 Granulocyte-macrophage colony-stimulating factor (GM-CSF) was produced in substantial amounts, but IL-3 production was minimal.
996 8288319 In contrast, spleen cells from mice immunized with SBP produced IL-2 but failed to produce IFN-gamma.

1002 8319241 The results were compared with the cytotoxicity exerted by lymphokine-activated killer (LAK) cells generated by interleukin-2 (IL-2) and interferon gamma (IFN gamma).
1003 8319241 BCG-stimulated PBMC showed a cytotoxic potential against BT-A and BT-B comparable to that of IFN gamma-generated LAK cells, but this did not reach the level of IL-2-generated LAK cells.
1004 8319241 We could demonstrate the presence of the cytokines IFN gamma, IL-2, tumour necrosis factor alpha (TNF alpha) and TNF beta in the supernatants harvested during the generation of BAK cells.
1005 8319241 The cells effective in BCG-activated killing of bladder tumour cells could be localized within the CD8+/CD56+ lymphocyte subset.
1006 8319241 Our findings imply that the activation by BCG of CD8+/CD56+ killer cells might be an important antitumoral mechanism during BCG therapy against superficial urothelial bladder cancer.

1017 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.
1018 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.
1019 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.
1020 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.
1021 8348563 Concanavalin-A-induced production of interleukin-2 (IL-2), IL-6, interferon gamma and tumour necrosis factor alpha was detected in more than 70% of the microcultures.
1022 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.
1023 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.
1024 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.
1025 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.
1026 8376936 Interestingly, both PP and SP CD4+ T cell cultures showed increased numbers of IL-4- and IL-5 (Th2-type)-producing, spot-forming cells (SFCs) after 21 d of immunization, while essentially no interferon-gamma (IFN-gamma) or IL-2 (Th1-type) SFCs were noted.

1101 8568254 CD4+ T cells produced IFN-gamma and IL-2 as well as IL-10, but not IL-4 or IL-5.
1102 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.
1103 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.

1135 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.
1136 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.
1137 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.
1138 8604226 Additional cytokines such as IL-10 and IL-12 are likely to contribute to the regulation of this response.
1139 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.

1143 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.
1144 8621924 The systemic immunity generated by GM-CSF- or IL-4-transfected lymphoma required both CD4+ and CD8+ T cells.

1159 8625312 Cellular immune assays revealed that the addition of IL-2 to rV-CEA immunization significantly increased the CEA-specific T-cell proliferative responses as well as the cytolytic T-cell responses when compared with rV-CEA immunization alone.
1160 8625312 The enhanced CEA-specific immune response, coupled with the improved experimental therapeutic outcome following IL-2 administration, suggests that treatment with that cytokine may effectively substitute for multiple rV-CEA immunizations in active-specific immunotherapy clinical protocols directed at CEA-expressing tumors.
1161 8653680 We further show that in vitro stimulation of the postimmunization peripheral blood lymphocytes with the MAGE-1 nonapeptide-loaded antigen presenting cell and interleukin-2 leads to significant expansion of peptide-specific and autologous melanoma-reactive CTL response.
1162 8665571 We evaluated the in vivo response to the poorly immunogenic B16-BL6 (BL6) murine melanoma genetically altered to secrete interleukin-2 (IL-2), IL-4, interferon gamma (IFN gamma) and granulocyte/macrophage-colony-stimulating factor (GM-CSF).
1163 8665571 Secretion of IL-2 abrogated the tumorigenicity of BL6, while IFN gamma and IL-4 partially reduced tumorigenicity, and GM-CSF had no effect.
1164 8665571 Protective immunity to wild-type tumor challenge could not be achieved by vaccination with irradiated cytokine-secreting tumors, although IL-2 and IL-4 secretion appeared to retard the growth of the challenge inoculum significantly.

1486 8877133 IL-12 and IL-15 at doses up to 10 ng/ml had little effect on basal HIV-1 p24 antigen production by chronically HIV-infected T (ACH-2) and monocytic (U1) cell lines.
1487 8877133 For ACH-2 cells stimulated with phorbol 12-myristate 13-acetate (PMA; 50 ng/ml), IL-12 and IL-15 significantly increased p24 antigen production by 20 and 30%, respectively (n = 6).
1488 8877133 In contrast, IL-12 and IL-15 (10 ng/ml) treatment of PMA-stimulated U1 cells decreased p24 antigen production by 16 and 15%, respectively (n = 6).
1489 8877133 We next studied the effect of IL-12 and IL-15 on HIV-infected peripheral blood mononuclear cells (PBMCs).

1491 8877133 For the low-response pattern, IL-12 and IL-15 increased viral replication by 97-fold and 100-fold, respectively (P = 0.05 and 0.004, respectively).

1533 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.
1534 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.
1535 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.
1536 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.

1538 8901428 While tetanus toxoid antigen alone induced a typical Th1-like cytokine pattern with high levels of IL2 and IFN gamma, equivalent or antibody-excess immune complexes induced a marked secretion of IL6 and IL10 while failing to induce IL2 and IFN gamma secretion.

1609 8933818 Northern blot analysis revealed that 2 h after CA-5d, PECs expressed a high level of IL-2, IFN-gamma, IL-1 beta and a low level of IL-10 and TNF-alpha mRNAs, while IL-4 and IL-5 mRNAs were absent, suggesting the development of TH1 subset.

1618 8954146 Our results suggest that the CD8+ T lymphocytes are implicated in the anti-tumour reaction elicited by the IL-2-transfected cells.
1619 8955168 We have recently described the cDNA and predicted protein structure of a natural soluble CD4 ligand, IL-16.
1620 8955168 IL-16 is chemotactic for CD4+ T cells and induces functional IL-2 receptors in CD4+ T cells.
1621 8955168 The binding of IL-16 to CD4 results in activation of p56(lck), whose adaptor function is essential for the chemotactic response.
1622 8955168 Because of the similarities between these signals and functions and those noted for the CD4 ligand HIV-1 gp120, we investigated the potential regulatory effects of IL-16 on CD3/TCR-mediated lymphocyte activation.
1623 8955168 In addition, IL-16 had no effect on surface expression of CD3 or CD4.
1624 8955168 These studies indicate that while the interaction of CD4 with its natural ligand, IL-16, results in Ag-independent chemotaxis and IL-2R expression, this pro-inflammatory state is associated with subsequent transient inhibition of responsiveness via the CD3/TCR complex.

1653 8988846 Th1 cells have been characterised by the production of gamma-interferon, interleukin (IL)-2, tumour necrosis factor-beta (lymphotoxin-alpha) and the ability to mediate delayed-type hypersensitivity responses, and Th2 cells by their production of IL-4, IL-5, IL-6 and IL-10 and the ability to stimulate production of mast cells, eosinophils and IgE.
1654 8993754 These include the ability to augment and accelerate reactions of delayed hypersensitivity against antigens to which the test subject has been previously sensitized, and the ability to enhance the expression in vitro on CD4 lymphocytes of the p55 subunit of the receptor for Interleukin-2.
1655 8993754 We also report our observation that in a patient with advanced HIV disease whose lymphocytes had lost there ability to properly express the IL-2 receptor, treatment with IMREGR-1 over a period of months restored the expression of the IL-2 receptor on the patient's CD4+ lymphocytes towards normal.

1737 9052739 In control experiments, immunization using purified CAP antigen induced a predominant, but not exclusive, Th2-like profile as determined by the splenic production of IL-4 and IL-10.
1738 9052739 For all CAP immunogens, MHC haplotype of immunized mice was found to influence seroconversion rates but not the type of cytokines produced in vitro.
1739 9053442 Intraperitoneal administration of rmIL-12 shifted TT-specific responses toward Th1-type and resulted in CD4+ T cells producing IFN-gamma and IL-2 with markedly reduced levels of Th2-type cytokines.

1756 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.
1757 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.
1758 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.
1759 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.
1760 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).

1766 9108412 Our results show that CD8+ T cells from leukemic mice 1 and 2 weeks after leukemia inoculation proliferate more vigorously in response to in vitro activation than cells from normal mice and produce Th1-type cytokines interleukin-2 and interferon-gamma.
1767 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.
1768 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.

1874 9220581 After activation of T-lymphocytes with antigen there is an increase in the expression of interleukin-2 receptor-alpha (IL-2R-alpha) followed by the release of a soluble form of the molecule (sIL-2R-alpha) from the membrane of the stimulated cells.

1877 9220585 The pGEX-2T vector contained glutathione-S-transferase (GST) as the affinity handle and resulted in high level expression of the GST-IL-2 fusion protein.
1878 9220585 An alternative vector, pT7-7 was used with a 6 x histidine tag followed by a thrombin cleavage site at the amino terminus of the mature ovine IL-2 protein to allow affinity purification by Ni-NTA resin.

1881 9224970 Th1 favor rejection (tumoral, fetal or of transplants) through the elaboration of IL-2, IFN and TNF while Th2 led to tolerance or acceptation through the production of IL-4, IL-5 and IL-10: both functions neutralize each other establishing a "normal" equilibrium Th1 vs Th2.
1882 9226467 In order to improve suppressed immunogenicity of QRpP cells with the high levels of PGE2, the author transfected QRpP cells with an effective expression vector containing cDNA for IL-2, IFN-gamma and TNF-alpha.
1883 9226467 These transfected clones expressed mRNA for IL-2, IFN-gamma and TNF-alpha, respectively, and produced high levels of cytokines in their culture supernatants.
1884 9226467 Consequentry, QRpP cells transfected with IL-2 (QRpP-IL-2), IFN-gamma (QRpP-IFN-gamma), IL-2 and IFN-gamma (QRpP-IL-2/IFN-gamma), TNF-alpha (QRpP-TNF-alpha) lowered in tumorigenicity.

1891 9226836 Unexpectedly, iscom adjuvants also impaired immunity and, despite the highest DTH response, produced a low IgG2a response, suggesting that iscomization of the antigen produced a low interferon gamma and high interleukin 2 response.
1892 9233612 FACS analysis of T cells from MLN and lung tissue demonstrated that T cells expressing any of the activation markers tested (LFA-1, CD25, CD44, CD45RB, CD49d, CD62L) always expressed high levels of CD44 and LFA-1.
1893 9233612 These double-high T cells produced >99% of all anti-CD3 mAb-induced IL-4 and IFN-gamma.
1894 9233612 Despite their similar phenotype, purified double-high lung parenchyma T cells produced markedly higher levels of IL-2, IL-4, and IFN-gamma, and contained a higher frequency of cytokine producers than their MLN counterparts.
1895 9233612 Activation of the extracellular signal-regulated kinase (ERK)-2 in response to TCR cross-linking was detected in double-high T cells from lung tissue but not MLN.
1896 9233612 The requirement for ERK signaling for maximal IFN-gamma synthesis could nevertheless be demonstrated in both populations by blockade with the inhibitor PD98509.
1897 9234526 Ag85A and Ag85B encoding plasmids induced a robust Th1-like response towards native Ag85, characterized by elevated levels of interleukin (IL)-2, interferon-gamma, and TNF-alpha.
1898 9234526 Levels of IL-4, IL-6, and IL-10 were low or undetectable.
1899 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).
1900 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.
1901 9242454 At fibroblast: tumor cell ratios of < or=1, allogeneic and syngeneic granulocyte macrophage colony-stimulating factor-secreting fibroblasts enhanced T-cell reactivity to tumor cells.
1902 9242454 However, at ratios of 2.4, the adjuvant effect induced by granulocyte macrophage colony-stimulating factor was not evident.
1903 9242454 Allogeneic fibroblasts transduced to secrete interleukin 2 or IFN-gamma also induced diminished tumor reactivity of primed LN cells.
1904 9246204 Significant sustained interleukin-2 and interferon-gamma production towards BCG antigens was only found in M. scrofulaceum infection.
1905 9247574 We have previously reported decreased tumorigenicity of the murine plasmacytoma J558L [major histocompatibility complex (MHC) class I+ and class II-] expressing IL-2 or B7.1.
1906 9247574 We examined the mechanism underlying this unexpected result: 6 days after injection of J558-IL2/B7.1 cells, tumor were nearly completely destroyed and were almost devoid of CD8+ cells, while CD8+ cells were increased in both IL-2- and B7.1-transfected tumors.
1907 9247574 We have previously reported decreased tumorigenicity of the murine plasmacytoma J558L [major histocompatibility complex (MHC) class I+ and class II-] expressing IL-2 or B7.1.
1908 9247574 We examined the mechanism underlying this unexpected result: 6 days after injection of J558-IL2/B7.1 cells, tumor were nearly completely destroyed and were almost devoid of CD8+ cells, while CD8+ cells were increased in both IL-2- and B7.1-transfected tumors.
1909 9255766 The culture supernatants collected from 71-kDa stimulated lymphocytes stimulated exhibited increased interferon-gamma and interleukin-2 production.
1910 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.
1911 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.
1912 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.
1913 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.
1914 9272137 The identification of these minimal residual tumor (MRT) cells and systematic evaluation of their biologic characteristics may guide strategies to target these cells specifically; such strategies may include modification of chemotherapy, tumor vaccination, or other forms of biologic therapy, such as replacement of RB, 3p, and/or p53 function; interference with autocrine or paracrine growth loops; or immunologic therapy [interleukin (IL)-2, IL-12, immunotoxins, and tumor vaccines], which would be most effective in the setting of MRT.
1915 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.
1916 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.

1922 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.
1923 9272363 In contrast, peripheral blood mononuclear cells from vaccinated infants produced IL-2, IL-5 and IFN-g.
1924 9278182 We have also shown that tetanus toxoid (TT) specific CD4+ T cell clones, with a known cytokine production profile, were sensitive to the inhibitory effects of thiopental and exhibited decreased proliferation to TT as well as decreased secretion of IL-2.
1925 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.
1926 9278182 We have also shown that tetanus toxoid (TT) specific CD4+ T cell clones, with a known cytokine production profile, were sensitive to the inhibitory effects of thiopental and exhibited decreased proliferation to TT as well as decreased secretion of IL-2.
1927 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.
1928 9285313 Influence of some immune factors on the IL-6 and soluble IL-2 receptors in haemodialysed patients.
1929 9285313 The purpose of our study was to evaluate the effect of uraemic and haemodialysis factors on the interleukin-6 and interleukin-2 soluble receptor levels and the reactivity after influenza vaccination.
1930 9285313 We have found that IL-6 and IL-2 receptor levels were statistically significantly elevated (98.8 +/- 39 pg/ml and 1557 +/- 544 U/ml, respectively) in serum of haemodialysed patients.
1931 9285313 We conclude that the interleukin disturbance and the elevated interleukin-2 receptor levels together with the presence of circulating immune complexes can influence in some way the immune response of haemodialysed patients.

1944 9292418 C. neoformans-stimulated control PBMC released IL-2, IFN-gamma, and IL-10 into the supernatant with peak or near peak concentrations of these three cytokines generally seen by day 1.
1945 9292418 In contrast, C. neoformans-stimulated patient PBMC released IFN-gamma, which peaked on day 7, as well as IL-4, IL-10, and in one of two patients, IL-2.
1946 9292418 C. neoformans-stimulated control PBMC released IL-2, IFN-gamma, and IL-10 into the supernatant with peak or near peak concentrations of these three cytokines generally seen by day 1.
1947 9292418 In contrast, C. neoformans-stimulated patient PBMC released IFN-gamma, which peaked on day 7, as well as IL-4, IL-10, and in one of two patients, IL-2.
1948 9302743 The codelivery of vectors encoding IL-2, IL-7, or IL-12 blocked this effect by markedly enhancing gp120-specific interferon gamma production, and suppressing IL-4 and IgG1 responses.
1949 9302743 In this case, IFN-gamma production following in vitro stimulation increased by over 1000-fold, while IL-4, IgG1, and IgG2a responses were elevated as well.
1950 9302743 Interestingly, cytokine gene codelivery, in the context of the longer resting period, provided no additional stimulation of Th1-like responses such as IFN-gamma and IgG2a production, although there was still some suppression of IL-4 production.
1951 9310492 Bulk peripheral blood mononuclear cells (PBMCs) or enriched CD8+ T cells were stimulated for 10 days with autologous ALVAC-infected PBMCs in the presence of different cytokine combinations (interleukin-2 [IL-2], IL-4, IL-7, and IL-12).
1952 9310492 The ALVAC activation of CTLp was IL-2 dependent and enhanced by the addition of IL-7, whereas IL-4 and IL-12 failed to augment cytotoxic reactivities elicited by these constructs.
1953 9310492 The expansion of enriched CD8+ T cells after activation with vCP300 was higher in patients with CD4 counts greater than 400 cells/microL.
1954 9310492 Bulk peripheral blood mononuclear cells (PBMCs) or enriched CD8+ T cells were stimulated for 10 days with autologous ALVAC-infected PBMCs in the presence of different cytokine combinations (interleukin-2 [IL-2], IL-4, IL-7, and IL-12).
1955 9310492 The ALVAC activation of CTLp was IL-2 dependent and enhanced by the addition of IL-7, whereas IL-4 and IL-12 failed to augment cytotoxic reactivities elicited by these constructs.
1956 9310492 The expansion of enriched CD8+ T cells after activation with vCP300 was higher in patients with CD4 counts greater than 400 cells/microL.
1957 9314076 Extensive studies of the molecular basis of the latter phenomenon led to the conclusion that the most decisive step from non-specific microabscess formation to granulomatous inflammation is the activation of non-specifically invading CD4+ T cells, which results in high local concentrations of TNF-alpha and IFN-gamma in the presence of IL-2.
1958 9314076 Because any attempt to neutralize the effects of TNF-alpha and IFN-gamma to modulate T-cell-mediated inflammation will also dramatically decrease host resistance, other anti-inflammatory strategies based on the modulation of TNF-alpha and IFN-gamma-induced mechanisms of monocyte accumulation must be developed.
1959 9315484 A variety of cytokines such as granulocyte/macrophage colony-stimulating factor (GM-CSF), IL-2, IL-4, IL-12 and IFN-gamma, as well as the costimulatory molecule B7.1, have been tested to date for their ability to amplify the immune response to genetic vaccines.
1960 9336741 We have transfected human melanoma cell line 518A2 with the cDNA encoding interleukin-2 (IL-2) or granulocyte-macrophage colony-stimulating factor (GM-CSF), and compared cytokine-producing clones for their ability to induce melanoma-specific cytotoxic T lymphocytes (CTL) from autologous peripheral blood mononuclear cells (PBMC) in vitro.
1961 9336741 The parental cell line expressed HLA-A1, HLA-A2, ICAM-1, LFA-3, in addition to the common CTL antigens MAGE-1, MAGE-3, tyrosinase, gp100, and Melan-A/MART-1.
1962 9341783 Therefore, we analyzed the C26 murine colon carcinoma genetically modified to release interleukin (IL)-2, IL-4, IL-12, granulocyte colony-stimulating-factor (CSF) or granulocyte-macrophage (GM)-CSF for immunostaining with the monoclonal antibody NDLC145 recognizing the DEC205 determinant which, on tumor sections, is virtually restricted to DC.
1963 9341783 Infiltrating leukocytes were also characterized for expression of co-stimulatory molecules like CD54, CD86 and major histocompatibility complex class II.
1964 9341783 The intratumoral DC content was dependent on the type of transduced cytokines with C26/IL-4 being the most abundant in DEC205+ cells.
1965 9341783 In comparison with C26/GM-CSF, C26/IL-4 had more B7.2+ cells but less Ia+ cells.
1966 9341783 Furthermore, the hypertrophic skin overlaying tumors producing GM-CSF showed numerous Langerhans cells stained by NDLC145 and the draining lymph nodes showed abundance and paucity of DC in C26/GM-CSF and C26/IL-4, respectively.
1967 9341783 When injected into the ear pinna, C26/GM-CSF stimulated, whereas C26/IL-4 inhibited DC-mediated priming of delayed-type hypersensitivity reaction by 2,4-dinitro-1-fluorobenzene.
1968 9349474 The intravenous infection of the C8 variant of the SIVmac251/32H virus, carrying an in-frame 12 bp deletion in the nef gene, did not affect the CD4+ and CD8+ cell counts, and a persistent infection associated with an extremely low virus burden in peripheral blood mononuclear cells (PBMCs) was established.
1969 9349474 Furthermore, in contrast to the control monkeys, the vaccinated monkeys showed normal levels for CD4+ and CD8+ cells, minimal lymphoid hyperplasia and no clinical signs of infection.
1970 9349474 This appears to be dependent on the ability of the C8 variant to establish a persistent but attenuated infection which is necessary for inducing an immune response, as suggested by the persistence of a strong immune B cell memory and by the over-expression of interleukin (IL)-2, interferon-gamma and IL-15 mRNAs in PBMCs of C8-vaccinated monkeys but not in those of control monkeys.
1971 9363590 Serial plasma collected from the volunteers from day 0 (before infection) to day 17 after infection were examined for levels of soluble interleukin-2 receptor (sIL-2R), soluble CD4 (sCD4), soluble CD8 (sCD8), interleukin-2 (IL-2) and interferon gamma (INF gamma).
1972 9363590 Elevation of the levels of sIL-2R, IFN gamma, sCD4 and IL-2 became obvious during the period of viremia and was followed by a later increase in the level of sCD8.
1973 9363590 T cells are activated in vivo by dengue virus infection ii. activation of CD4+ T cells occurs during the period of viremia iii. activation of CD8+ T cells follows CD4+ T cell activation.
1974 9363590 Serial plasma collected from the volunteers from day 0 (before infection) to day 17 after infection were examined for levels of soluble interleukin-2 receptor (sIL-2R), soluble CD4 (sCD4), soluble CD8 (sCD8), interleukin-2 (IL-2) and interferon gamma (INF gamma).
1975 9363590 Elevation of the levels of sIL-2R, IFN gamma, sCD4 and IL-2 became obvious during the period of viremia and was followed by a later increase in the level of sCD8.
1976 9363590 T cells are activated in vivo by dengue virus infection ii. activation of CD4+ T cells occurs during the period of viremia iii. activation of CD8+ T cells follows CD4+ T cell activation.
1977 9364701 To test this concept, expression vectors were constructed containing the ovalbumin (OVA) gene either alone, or linked to cytokine genes including GM-CSF, IFN-gamma, IL-2, IL-4, IL-12, or a sequence encoding nine amino acids of IL-1 beta.
1978 9364701 However, lymphocytes from BALB/c mice vaccinated with OVA-IL-12 and OVA-IL-1 beta constructs produced more IFN-gamma and less IL-4 during in vitro restimulation assays than did other groups.
1979 9366440 Furthermore, we determined if coadministration of an IL-2 or GM-CSF DNA expression plasmid with a plasmid expressing the HCV core protein (pHCV2-2) would reverse the inhibitory effects of chronic ethanol feeding on cellular immune responses.
1980 9366440 Coimmunization of chronic ethanol-fed mice with either IL-2 or GM-CSF expression plasmids restored cellular immunity and induced CD4+ inflammatory T cell and CD8+ CTL responses comparable with control mice immunized with pHCV2-2 alone.
1981 9366440 Furthermore, we determined if coadministration of an IL-2 or GM-CSF DNA expression plasmid with a plasmid expressing the HCV core protein (pHCV2-2) would reverse the inhibitory effects of chronic ethanol feeding on cellular immune responses.
1982 9366440 Coimmunization of chronic ethanol-fed mice with either IL-2 or GM-CSF expression plasmids restored cellular immunity and induced CD4+ inflammatory T cell and CD8+ CTL responses comparable with control mice immunized with pHCV2-2 alone.
1983 9379055 Purified populations of bovine immune and naive CD8+ T cells were cocultured with autologous T. parva-infected lymphoblasts (TpL) in the presence or absence of immune CD4+ T cells or cytokine preparations.
1984 9379055 Neither population developed CTL activity when cultured with TpL alone, whereas incorporation of immune CD4+ T cells in the cultures supported the generation of parasite-specific CTL from both immune and naive CD8+ precursors.
1985 9379055 The helper function of parasite-specific CD4+ T cells for immune, but not naive, CTL precursors could be replaced by CD4+ T cells responding to an unrelated Ag or by the addition of T cell growth factors or recombinant bovine IL-2.
1986 9379055 In experiments with two-chamber culture plates, in which cocultures of CD4+ and CD8+ T cells with TpL were separated by a semipermeable membrane, CTL activity was observed to develop only in immune precursor populations.
1987 9379055 Hence, although bovine T. parva-specific CD8+ memory T cells need no helper signals other than IL-2 for activation, their naive counterparts require close contact with responding parasite-specific CD4+ T cells.
1988 9379055 Purified populations of bovine immune and naive CD8+ T cells were cocultured with autologous T. parva-infected lymphoblasts (TpL) in the presence or absence of immune CD4+ T cells or cytokine preparations.
1989 9379055 Neither population developed CTL activity when cultured with TpL alone, whereas incorporation of immune CD4+ T cells in the cultures supported the generation of parasite-specific CTL from both immune and naive CD8+ precursors.
1990 9379055 The helper function of parasite-specific CD4+ T cells for immune, but not naive, CTL precursors could be replaced by CD4+ T cells responding to an unrelated Ag or by the addition of T cell growth factors or recombinant bovine IL-2.
1991 9379055 In experiments with two-chamber culture plates, in which cocultures of CD4+ and CD8+ T cells with TpL were separated by a semipermeable membrane, CTL activity was observed to develop only in immune precursor populations.
1992 9379055 Hence, although bovine T. parva-specific CD8+ memory T cells need no helper signals other than IL-2 for activation, their naive counterparts require close contact with responding parasite-specific CD4+ T cells.
1993 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.
1994 9384286 In this study, we found that IL-4 significantly suppressed IL-1beta secretion induced by BCG and the 70- and 65-kDa HSP.
1995 9384286 When exogenous recombinant human IL-4 was added to human mononuclear cells, a dose- and time-related inhibition of the 70-kDa HSP- and BCG-induced IL-1beta secretion was observed.
1996 9384286 In addition, IL-2, another T-cell-derived cytokine acting on monocytes, had no effect on IL-1beta secretion induced by either BCG or the 70-kDa HSP, indicating that in these experiments not all cytokines could immunoregulate IL-1beta secretion.

2180 9621023 Protective CD4+ and CD8+ T cells against influenza virus induced by vaccination with nucleoprotein DNA.
2181 9621023 In the present study, we have characterized in more detail the cellular immune responses induced by NP DNA, which included robust lymphoproliferation and Th1-type cytokine secretion (high levels of gamma interferon and interleukin-2 [IL-2], with little IL-4 or IL-10) in response to antigen-specific restimulation of splenocytes in vitro.

2199 9632584 Mucosal delivery of murine interleukin-2 (IL-2) and IL-6 by recombinant strains of Lactococcus lactis coexpressing antigen and cytokine.
2200 9632584 To determine whether lactococci can also deliver cytokines to the immune system, we have constructed novel constitutive expression strains of L. lactis which accumulate a test antigen, tetanus toxin fragment C (TTFC), within the cytoplasmic compartment and also secrete either murine interleukin-2 (IL-2) or IL-6.

2255 9652756 Our data indicate that B7.1- and B7.2-transduced melanoma cells trigger lymphocytic proliferation with transcription of IL-10, IL-2 and IFN-gamma.
2256 9656448 For instance, at high doses IL-2 can induce autoimmune disease and interferon gamma can have a suppressive effect.
2257 9656453 In addition, the cytokine profiles support the T1rT2 differentiation with these immunizations, in that oxidized mannan antigen gives IFNg, IL-2 and IL-12 production, whereas in the absence of oxidization, IL-4 and not the other cytokines is produced.
2258 9664134 We also compared the immunogenic activity of vaccines made from B16 melanoma cells transfected with genes encoding murine IL-2 or GM-CSF, and effects on tumor bearing mice were compared with or without therapy using the corresponding lymphokines.
2259 9670850 However, they produced high levels of IL2, TNFalpha and IL10.
2260 9670986 Coculture with CD4+ T cells induced optimal gamma delta T cell expansion, although IL-2 alone could provide this helper function in the absence of CD4+ T cells.
2261 9670986 Gamma delta T cells were found to provide helper functions for mycobacterial specific CD4+ and CD8+ T cells as well, demonstrating reciprocal stimulatory interactions between gamma delta T cells and other T cell subsets.
2262 9673264 The expression of mRNA of gamma interferon (IFN-gamma), interleukin-2 (IL-2), IL-4, and IL-5 in the peripheral blood mononuclear cells (PBMCs) was assayed by reverse transcription-PCR.
2263 9673264 At least one of the antigens induced mRNA for IL-4 and/or IL-5 in the cells of 93% of tested vaccinees and patients, and FHA induced IFN-gamma mRNA in the cells of two-thirds of them.

2289 9682333 Gp63-ISCOMs primed spleen cells restimulated in vitro with soluble Leishmania antigen (SLA) or live parasites displayed strong gp63-specific proliferative responses and secreted high levels of interleukin-2, interferon gamma and interleukin-10 but not interleukin-4.
2290 9682357 After oral immunization of BALB/c mice with two 1 x 10(9) colony forming unit doses given 21 days apart, CVD 908 omega (delta aroC::Ptac-gp63) elicited a broad T cell-mediated immune response against L. m. mexicana gp63 as demonstrated by: (1) lymphoproliferative response to fixed whole L. m. mexicana promastigotes; (2) activation of IL-2 (but not IL-4)-producing lymphocytes; (3) appearance of cytotoxic T cells against mouse mastocytoma cells expressing gp63.
2291 9682365 Ocular pre-exposure to DNA encoding the cytokines interleukin (IL)-4 or IL-10, but not IL-2 or interferon-gamma, modulated the severity of the immunoinflammatory response to subsequent corneal infection with HSV.
2292 9682366 Administration of human growth hormone at the time of gp120 immunization provokes a change in the cytokine production pattern, with lower IL-4 and higher gamma-IFN and IL-2 synthesis levels, indicating a preferential switch in stimulation from Th2 to Th1 cells.
2293 9682391 To evaluate vaccinia virus as a delivery system for recombinant antigen in cattle, calves were immunized with a recombinant vaccinia virus (rVV) expressing the sporozoite surface antigen (p67) of Theileria parva (V-67) combined with those expressing bovine IL-4 (V-IL4) or IL-2 (V-IL2).
2294 9682391 Vaccination with a recombinant virus expressing a chimaeric p67(p583)/IL2 product gave rise to a lower level of protection, whereas V-IL2 provided no immunity.
2295 9682391 To evaluate vaccinia virus as a delivery system for recombinant antigen in cattle, calves were immunized with a recombinant vaccinia virus (rVV) expressing the sporozoite surface antigen (p67) of Theileria parva (V-67) combined with those expressing bovine IL-4 (V-IL4) or IL-2 (V-IL2).
2296 9682391 Vaccination with a recombinant virus expressing a chimaeric p67(p583)/IL2 product gave rise to a lower level of protection, whereas V-IL2 provided no immunity.
2297 9689679 This phase corresponds to the early release of so-called inflammatory cytokines (IL-1, IL-6, IL-8).
2298 9689679 The second phase consists of recognition of bacterial antigens by CD4 lymphocytes, which release mainly IL-2 and IFN-gamma(TH1 response).
2299 9689679 This cell activation leads to the third phase, which consists of amplification of cytotoxic-populations: CD8, gamma delta lymphocytes, macrophages, NK, LAK, BAK.
2300 9694595 The most common profile of urinary cytokines is interleukin-2 and interferon-gamma, suggesting the predominant involvement of the Th1 lymphocyte subpopulation.
2301 9695135 Ten weeks post-vaccination there were no differences between the experimental and control groups in serum levels of interleukin-1 beta, interferon-gamma, soluble interleukin-2 receptors (sIL-2r), and cortisol.
2302 9697728 B. pertussis antigen stimulation resulted in a preferential induction of type 1 cytokine profile, as shown by interferon-gamma and interleukin-2 (but no interleukin-4 or interleukin-5) gene transcripts and actual cytokine production by T cells.
2303 9697988 IL-2 therapy results in a significant increase in peripheral blood CD4+ lymphocyte count, but this increase is not associated with quantifiable improvements in lymphoproliferative responses to mitogens, recall or HIV antigens.
2304 9699714 The nature of the immune response depends on the route, method, and timing of DNA delivery and can also be influenced by co-delivery of plasmids encoding immunomodulating cytokines like IFN-alpha, IL-2, or IL-12 and costimulatory molecules like B7-1.
2305 9711781 Maturation of human neonatal CD4+ and CD8+ T lymphocytes into Th1/Th2 effectors.
2306 9711781 The activation and maturation of neonatal CD4+ T cells is particularly dependent upon the strength of CD28-mediated cosignal which dictates not only the cytokine profile released upon primary activation but also the response to IL-12.
2307 9711781 Activation of adult as well as neonatal CD4+ T cells in the context of low CD28 costimulation yields to the production of low levels of only one cytokine, i.e.
2308 9711781 In contrast, strong CD28 costimulation supports the production of high levels of type 1 (IL-2, IFN gamma and TNF beta) and low levels of type 2 (IL-4 and IL-13) cytokines by neonatal T cells.
2309 9711781 The low levels of naive T cell-derived IL-4 are sufficient to support their development into high IL-4/IL-5 producers by an autocrine pathway.
2310 9711781 The ability of IL-12 to prime neonatal CD4+ T cells for increased production of IL-4 (in addition to IFN gamma) is observed only when CD28 cosignal is minimal.
2311 9711781 Unlike CD4+ T cells, neonatal CD8+ T cells strictly require exogenous IL-4 to develop into IL-4/IL-5 producers.
2312 9711781 Most importantly, anti-CD3/B7-activated neonatal CD8 T cells coexpress CD4 as well as CCR5 and CXCR4 and are susceptible to HIV-1 infection in vitro.
2313 9712080 Intradermal vCP-LAIgp160 injection induced an intradermal perivascular human lymphocytic infiltrate and an epidermic network of CD1a+, CD80+, and CD86+ cells.

2317 9712369 The TIL cultures were initiated using OKT3 mAb in the presence of moderate concentrations (25-50 U/ml) of IL-2, followed by 100 U/ml of tumor necrosis factor (TNF)-alpha.
2318 9712369 TAL were not stimulated with OKT3 mAb, but all were successfully expanded in culture in the presence of IL-2 alone or together with TNF-alpha.
2319 9720647 Here we describe that aging is associated with the emergence of an unusual CD4 T cell subset characterized by the loss of CD28 expression.
2320 9720647 Despite the deficiency of CD28, these unusual T cells remain functionally active and produce high concentrations of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2).
2321 9720647 The loss of CD28 expression is correlated with a lack of CD40 ligand expression rendering these CD4 T cells incapable of promoting B cell differentiation and immunoglobulin secretion.
2322 9720647 We propose that the emergence of CD28-deficient CD4 T cells in the elderly can partially explain age-specific aberrations in immune responsiveness.
2323 9725227 A plasmid encoding murine granulocyte-macrophage colony-stimulating factor increases protection conferred by a malaria DNA vaccine.
2324 9725227 We now report that mixing a new plasmid PyCSP1012 with a plasmid encoding murine granulocyte-macrophage colony-stimulating factor (GM-CSF) increases protection against malaria, and we have characterized in detail the increased immune responses due to GM-CSF.
2325 9725227 GM-CSF plasmid increased Abs to PyCSP of IgG1, IgG2a, and IgG2b isotypes, but not IgG3 or IgM.
2326 9725227 IFN-gamma responses of CD8+ T cells to the PyCSP 280-288 amino acid epitope increased but CTL activity did not change.
2327 9725227 The most dramatic changes after adding GM-CSF plasmid were increases in Ag-specific IL-2 production and CD4+ T cell proliferation.
2328 9725227 We hypothesize that GM-CSF may act on dendritic cells to enhance presentation of the PyCSP Ag, with enhanced IL-2 production and CD4+ T cell activation driving the increases in Abs and CD8+ T cell function.

2334 9725227 We hypothesize that GM-CSF may act on dendritic cells to enhance presentation of the PyCSP Ag, with enhanced IL-2 production and CD4+ T cell activation driving the increases in Abs and CD8+ T cell function.
2335 9733821 To modulate the antiviral immune response induced by live attenuated SIV vaccines, we had previously infected rhesus monkeys with a nef deletion mutant of SIV expressing interleukin 2 (SIV-IL2) (B.
2336 9733821 Since the SIV-MLV hybrid uses the MLV Env receptor Pit2 and not CD4 and a coreceptor for virus entry, chemokine inhibition and receptor interference phenomena were not involved in protection.
2337 9733872 To address these issues, we quantitated virus-specific CD4 Th1 (interleukin 2 [IL-2] and gamma-interferon) and Th2 (IL-4) responses in mice acutely infected with lymphocytic choriomeningitis virus (LCMV).

2350 9767429 Restimulated immune lymphoid cells showed enhanced production of both IL-2 and interferon-gamma and reduced secretion of IL-4.
2351 9814600 The detection of specific antibody became possible when antigen-selected B cells were cultured for 7 days in the CD40 system to induce clonal expansion, followed by the addition of IL-2 and IL-10 for an additional 7 days to induce plasma-cell differentiation.
2352 9815634 The clinical and immunological effects of a vaccine consisting of CTP37, a synthetic peptide corresponding to the COOH-terminal peptide (CTP) of beta-human chorionic gonadotropin (beta-hCG) conjugated to diphtheria toxoid, combined with CRL 1005, a novel synthetic nonionic block copolymer adjuvant, were examined.
2353 9815634 Responding PBMCs specifically secreted the TH1-associated cytokines IFN-gamma and interleukin (IL)-2 as well as the TH2-associated IL-5 and IL-10.
2354 9815634 Increased expression of IFN gamma and IL-5 mRNAs by PBMCs 4 h after immunization was also observed.
2355 9815645 We report here the serial phenotypic characterization of a CTL line directed against an immunodominant epitope (YLSGANLNL, designated CAP-1) of human carcinoembryonic antigen (CEA).
2356 9815645 This CTL line was derived from peripheral blood mononuclear cells of a patient with metastatic carcinoma who had been treated with a recombinant CEA-vaccinia vaccine in a Phase I trial; the CTLs were analyzed through 20 in vitro cycle passages of stimulation with CAP-1 peptide and interleukin 2 in the presence of autologous antigen-presenting cells.
2357 9815645 The CTL line was shown to be phenotypically stable in terms of high levels of cytokine (IFN-gamma, tumor necrosis factor, and granulocyte-macrophage colony-stimulating factor) production, expression of homing-adhesion molecules, ability to lyse peptide-pulsed targets, and ability to lyse human carcinoma cells endogenously expressing CEA in a MHC-restricted manner.
2358 9815761 Granulocyte-macrophage colony-stimulating factor (GM-CSF; 100 microgram) and MART-1(27-35) peptide (128 microgram in DMSO) were formulated into p-GlcNAc.

2364 9822287 Blood-derived DC up-regulated MHC class II, CD54, CD80 and CD86 after exposure to WV vaccine, indicating their functional maturation, but were only moderately affected by subunit (SU) vaccines.
2365 9822287 The production of IL-2 and interferon-gamma (IFN-gamma) by PBMC was also strongly stimulated by WV, but much less by SU vaccines, among which the v-SU vaccine was a better stimulator of IL-2 secretion.
2366 9824496 Determination of cytokine co-expression in individual splenic CD4+ and CD8+ T cells from influenza virus-immune mice.
2367 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.
2368 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.
2369 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.

2384 9826461 Combination of transforming growth factor beta antisense and interleukin-2 gene therapy in the murine ovarian teratoma model.
2385 9826461 The immunosuppressive protein transforming growth factor beta (TGF-beta) inhibits the activation of various immune effector cells including cytotoxic T lymphocytes and may therefore inhibit the efficacy of immunostimulatory interleukin-2 (IL-2) gene therapy.
2386 9826461 In this study, we investigated the effect of TGF-beta downregulation on IL-2 gene therapy in the intraperitoneal model of murine ovarian teratoma (MOT).
2387 9826461 Subcutaneous immunization of C3H mice with a mixture of IL-2 gene-transduced fibroblasts and TGF-beta antisense-modified MOT cells induced significantly better protection against a subsequent intraperitoneal tumor challenge compared with immunization with unmodified MOT cells alone [11/16 (69%) vs 4/21 (19%) tumor-free animals, P < 0.01].
2388 9826461 Immunization with either a mixture of IL-2 gene modified fibroblasts and unmodified MOT cells [2/12 (17%) tumor-free animals] or TGF-beta antisense-modified MOT cells alone (0/13 tumor free animals) failed to induce significant protection compared with immunization with unmodified MOT cells.
2389 9826461 These data show that combined TGF-beta antisense and IL-2 gene therapy is required to generate effective antitumor responses in the MOT model.

2394 9826461 Immunization with either a mixture of IL-2 gene modified fibroblasts and unmodified MOT cells [2/12 (17%) tumor-free animals] or TGF-beta antisense-modified MOT cells alone (0/13 tumor free animals) failed to induce significant protection compared with immunization with unmodified MOT cells.
2395 9826461 These data show that combined TGF-beta antisense and IL-2 gene therapy is required to generate effective antitumor responses in the MOT model.

2420 9829759 However, delayed type hypersensitivity to CEA and CEA-specific interleukin-2 release were observed only in the i.m. group, suggesting a qualitative difference in the character of the immune response elicited by the two techniques of DNA immunization.
2421 9834076 Female rhesus macaques were nasally immunized with p55gag (p55) of SIV and cholera toxin as a mucosal adjuvant.
2422 9834076 Furthermore, high numbers of p55-specific IgA and IgG Ab-forming cells were induced in mucosal effector sites, i.e., uterine cervix, intestinal lamina propria, and nasal passage. p55-specific CD4+ T cells in both systemic and mucosal compartments expressed IFN-gamma and IL-2 (Th1-type)- as well as IL-5, IL-6, and IL-10 (Th2-type)-specific mRNA.
2423 9834076 These results show that nasal immunization with SIV p55 with cholera toxin elicits both Th1- and selective Th2-type cytokine responses associated with the induction of SIV-specific mucosal and serum Abs, and CTL activity.
2424 9842896 Enhancement of protective humoral (Th2) and cell-mediated (Th1) immune responses against herpes simplex virus-2 through co-delivery of granulocyte-macrophage colony-stimulating factor expression cassettes.
2425 9842896 Granulocyte-macrophage colony-stimulating factor (GM-CSF) could in theory attract antigen-presenting cells in muscle following intramuscular DNA immunization, resulting in enhanced antigen-specific immune responses.
2426 9842896 GM-CSF cDNA co-injection enhanced levels of specific IgG, IgE and IgA against HSV-2 gD protein significantly higher than gD plasmid vaccination alone.
2427 9842896 T helper cell proliferation and secretion of cytokines (IL-2 and IFN-gamma) were significantly increased by GM-CSF cDNA co-injection.
2428 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.
2429 9858908 Using immunohistochemical analysis we demonstrated that after treating with lethally irradiated MBT-2 tumor cells (IRMBT-2) + IL-2 cells of CD4+, CD8+, CD44+ and CD11b+ phenotypes prominently infiltrate the subcutaneous local injection sites.
2430 9858908 In contrast, only scanty immune responding cells could be seen locally if treated with IRMBT-2 + IFN-alpha 2b, albeit in the presence of interleukin-2 (IL-2).
2431 9858908 However, the spleens of D17TBM treated with IRMBT-2 + IFN-alpha 2b contained the highest percentage of CD44+ memory T cells and cells of the CD11b+ phenotype; moreover, their natural killer (NK), lymphokine activated killer (LAK) and cytotoxic T lymphocytes (CTL) activities were significantly augmented.
2432 9858908 Using immunohistochemical analysis we demonstrated that after treating with lethally irradiated MBT-2 tumor cells (IRMBT-2) + IL-2 cells of CD4+, CD8+, CD44+ and CD11b+ phenotypes prominently infiltrate the subcutaneous local injection sites.
2433 9858908 In contrast, only scanty immune responding cells could be seen locally if treated with IRMBT-2 + IFN-alpha 2b, albeit in the presence of interleukin-2 (IL-2).
2434 9858908 However, the spleens of D17TBM treated with IRMBT-2 + IFN-alpha 2b contained the highest percentage of CD44+ memory T cells and cells of the CD11b+ phenotype; moreover, their natural killer (NK), lymphokine activated killer (LAK) and cytotoxic T lymphocytes (CTL) activities were significantly augmented.
2435 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.
2436 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.
2437 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.
2438 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.
2439 9864210 RAP-1-specific T helper (Th) cell clones that coexpress IFN-gamma and IL-4 are typical of numerous parasite-specific clones examined.
2440 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.
2441 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.
2442 9916741 Significant levels of highly Ag-specific Abs and Th1-type cytokines IL-2 and IFN-gamma could be detected following vaccination with each of the three genes.
2443 9930305 In this study we describe the generation and characterization of replication incompetent herpes simplex virus type 1 (HSV-1) vectors (HX86Z or HX86G) carrying distinct and independently regulated expression cassettes for five transgenes (hIL-2, hGM-CSF, hB7.1, HSV-tk and lacZ or hIFN gamma).
2444 9930305 Deletion of the immediate--early genes ICP4, ICP22 and ICP27 substantially reduced vector cytotoxicity, prevented early and late viral gene expression and left intact MHC class I antigen expression.
2445 9933432 Urine of patients showed increased levels of IL-1beta, IL-2, IL-6, tumour necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) and macrophage colony-stimulating factor (M-CSF) after BCG instillation.
2446 9933432 Levels of IL-2 and IFN-gamma in the serum also increased after BCG instillation, but IL-1beta, IL-6, TNF-alpha and M-CSF were not detectable.
2447 9933432 Maximal levels of IL-2 and IFN-gamma in the urine or serum were shown after the fourth instillation.
2448 9933432 Urine of patients showed increased levels of IL-1beta, IL-2, IL-6, tumour necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) and macrophage colony-stimulating factor (M-CSF) after BCG instillation.
2449 9933432 Levels of IL-2 and IFN-gamma in the serum also increased after BCG instillation, but IL-1beta, IL-6, TNF-alpha and M-CSF were not detectable.

2451 9933432 Urine of patients showed increased levels of IL-1beta, IL-2, IL-6, tumour necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) and macrophage colony-stimulating factor (M-CSF) after BCG instillation.
2452 9933432 Levels of IL-2 and IFN-gamma in the serum also increased after BCG instillation, but IL-1beta, IL-6, TNF-alpha and M-CSF were not detectable.
2453 9933432 Maximal levels of IL-2 and IFN-gamma in the urine or serum were shown after the fourth instillation.
2454 9935185 Anti-tumor activity of interleukin-2-producing tumor cells and recombinant interleukin 12 against mouse glioma cells located in the central nervous system.
2455 9935185 Although IL-12 itself activates strong anti-tumor activity, the combination of vaccine therapy with IL-2-transduced tumor cells and systemic rIL-12 has been shown to cure tumor-bearing mice more effectively than either rIL-12 or IL-2-transduced tumor vaccines alone.
2456 9935185 In the present study, regression of brain tumors established in naive mice was obtained by combined administration of an intratumoral injection of a single dose of IL-2-producing glioma cells (SR/IL-2 cells) and recombinant IL-12.

2462 9935185 In the present study, regression of brain tumors established in naive mice was obtained by combined administration of an intratumoral injection of a single dose of IL-2-producing glioma cells (SR/IL-2 cells) and recombinant IL-12.
2463 9973457 Mucosally induced systemic T cell unresponsiveness to ovalbumin requires CD40 ligand-CD40 interactions.
2464 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.
2465 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.
2466 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.
2467 9973457 In contrast, an identical culture condition containing splenic CD4+ T cells from orally tolerized CD40L+/+ mice did not exhibit helper activity.
2468 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.
2469 9973465 Lymphotactin (Lptn) is a C chemokine produced predominantly by NK and CD8-positive (CD8+) T cells including gammadelta TCR-positive (TCR+) intraepithelial lymphocytes.
2470 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.
2471 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.
2472 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.
2473 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.
2474 10048771 We observed that coinjection with IL-2, IL-4, IL-10, and GM-CSF resulted in increased levels of antigen-specific antibodies.
2475 10048771 We also observed that coadministration of IL-2, IL-12, and GM-CSF genes resulted in a dramatic enhancement of Th proliferation responses.
2476 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.

2479 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.
2480 10048771 We observed that coinjection with IL-2, IL-4, IL-10, and GM-CSF resulted in increased levels of antigen-specific antibodies.
2481 10048771 We also observed that coadministration of IL-2, IL-12, and GM-CSF genes resulted in a dramatic enhancement of Th proliferation responses.
2482 10051503 On HBsAg stimulation, leukocyte samples from a significantly higher proportion of subjects produced cytokines (81% of T cells produced interleukin-2 [IL-2] and 100% produced IL-5).
2483 10051503 Cellular immunity was augmented with a positive rate of 58%, 90%, and 100% for HBsAg-induced T-cell proliferation, IL-2 production, and IL-5 production, respectively.
2484 10051503 On HBsAg stimulation, leukocyte samples from a significantly higher proportion of subjects produced cytokines (81% of T cells produced interleukin-2 [IL-2] and 100% produced IL-5).
2485 10051503 Cellular immunity was augmented with a positive rate of 58%, 90%, and 100% for HBsAg-induced T-cell proliferation, IL-2 production, and IL-5 production, respectively.
2486 10051630 IL-2 could augment the efficacy of tumor lysate-pulsed DC to induce protective immunity to lethal tumor challenge as well as enhance splenic cytotoxic T lymphocyte activity and interferon-gamma production in these treated mice.
2487 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.
2488 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.
2489 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.
2490 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.
2491 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.
2492 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.
2493 10068569 Soluble CD8 and soluble interleukin-2 receptor levels were also elevated in children with DHF compared with those with DF.
2494 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.
2495 10072509 Thus, IL-4 may augment CD8+ T cell growth, but also limit effector function.
2496 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.
2497 10072509 Secretion of IL-2 and IFN-gamma by CD8+ T cells from IL-4-deficient mice was also elevated, reflecting their enhanced activation.
2498 10072509 Thus, IL-4 appears to limit the activation, expansion, and differentiation of CD8+ T cells with high cytolytic potential.
2499 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.
2500 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.
2501 10072541 However, the production of cytokines (IL-4 and IL-10) and chemokine (MCP-1) was inhibited by IL-12 coinjection.
2502 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.
2503 10072562 Despite normal proliferation and IL-2 secretion, IL-12 and IFN-gamma secretion in vitro in response to the vaccine was reduced compared with healthy volunteers.
2504 10072562 Finally, experiments in HBV transgenic mice indicated that the nonnatural Pan DR HTL epitope, PADRE, is capable of inducing high levels of IFN-gamma secretion and that its inclusion in a lipopeptide incorporating an immunodominant Ld-restricted CTL epitope resulted in breaking tolerance at the CTL level.
2505 10073726 In order to enhance the level of HIV-1 specific immunity, we have engineered HIV-1 DNA constructs which contained various cytokine genes such as interleukin-2 (IL-2), granulocyte-macrophage colony stimulating factor (GM-CSF) and interferon-gamma (IFN-gamma) gene.
2506 10073726 However, inoculations of HIV-1 DNA that contained the GM-CSF or the IL-2 gene significantly enhanced humoral and proliferative T cell responses, respectively.
2507 10073726 In order to enhance the level of HIV-1 specific immunity, we have engineered HIV-1 DNA constructs which contained various cytokine genes such as interleukin-2 (IL-2), granulocyte-macrophage colony stimulating factor (GM-CSF) and interferon-gamma (IFN-gamma) gene.
2508 10073726 However, inoculations of HIV-1 DNA that contained the GM-CSF or the IL-2 gene significantly enhanced humoral and proliferative T cell responses, respectively.
2509 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.
2510 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.
2511 10077167 Long-term survival and complete cures of B16 melanoma-carrying animals after therapy with tumor-targeted IL-2 and SEA.
2512 10077167 In contrast, the immune response after combination therapy was characterized by substantially augmented IFN-gamma and TNF-alpha production and strong CTL activity.
2513 10092787 Proliferative responses and production of the Th1 cytokines, IL-2 and IFN-gamma, were reduced in T cells responsive to PLP139-151.
2514 10092787 In the brains of mice that were successfully vaccinated, mRNA for IL-2, IL-15, and IFN-gamma were reduced.

2539 10195636 The following results were obtained: (1) The efficiency of encapsulation in liposomes was 95, 90 and 38% for HN, IL-2 and GM-CSF, respectively, and the liposomal preparations were highly stable as an aqueous dispersion for > 2 months at 4 degrees C. (2) Following immunization with 0.5 microg Lip-HN, there was an earlier, up to 50-fold stronger, and 3-5 times longer response than that obtained with nonliposomal HN. (3) Coimmunization with free cytokines further increased the response 2-20 times and the two cytokines had an additive effect. (4) Liposomal cytokines were 2-20 times more effective than the free cytokines and their stimulatory effect was more durable. (5) A 100% seroconversion (HI titer > or = 40) was achieved with only 10-25% of the routinely used antigen dose, by encapsulating either antigen or cytokine. (6) The level of protection following vaccination with the combined liposomal vaccines was 70-100% versus 0-25% in mice immunized with Al-HN alone, and no toxicity was observed.

2583 10233683 Further study to find the mechanism underlying this revealed that there was up-regulation of major histocompatibility complex (MHC) class II, CD86 antigens on DC and increased production of interleukin-12 (IL-12) by DC and of IL-2, and tumour necrosis factor-alpha (TNF-alpha) in DC/T-cell cultures when vaccine containing HBsAg was injected in HBV-Tg with potent DC function but not in HBV-Tg with poor DC function.
2584 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.
2585 10233736 This resulted in a strong interferon-gamma:IL-4 ratio, suggesting a skewing of the immune response towards a Type 1 response.

2597 10333238 Vaccinated animals, but not unvaccinated animals, had CD3+, CD4+, and gamma-delta T cells that significantly (p < 0.05) increased expression of CD25 when incubated with BHV1.
2598 10333238 CD8+ T cells from vaccinated animals did not consistently increase CD25 expression when incubated with inactivated BHV1.
2599 10353870 Cytokine analysis showed that interferon-gamma, interleukin (IL)-2, IL-5, IL-6, and IL-10 were induced by nasal immunization, suggesting that Th2- and Th1-type cells were generated.

2602 10386864 Human IL-2 or IL-15-induced CTLL proliferation was not blocked by rChIL-2 or polyclonal anti-rChIL-2 antibodies, indicating that chicken IL-2 cannot act as an antagonist of the mammalian IL-2 response.
2603 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.
2604 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.

2631 10404432 Renca/IFN-gamma produced subcutaneous (s.c.) tumors in all Balb/c nude mice, but Renca/IL-2 and Renca/GM-CSF did not.
2632 10404432 To test the elicitation of antitumor activity, Balb/c mice were injected intravenously with 1 x 10(5) W/Renca on day 0, vaccinated, s.c., with 1 x 10(6) cells each of 5,000 rad preirradiated Renca/IL-2, Renca/IFN-gamma, and Renca/GM-CSF or 3 x 10(6) cells of preirradiated W/Renca on days 1, 7, and 14, and radiated with 300 rad to both lungs on day 5.

2669 10419048 Immunohistochemical analysis revealed cellular infiltrates (granulocytes, macrophages, and CD4+ and CD8+ T cells) at both the vaccine site and the tumor site, indicating that immune responses were similarly activated when tumor vaccine was inoculated in the brain, as at the subcutis.
2670 10419048 Additional studies demonstrated that the therapeutic effects of tumor vaccines on the large tumors or the long-existing tumors were enhanced by strategies such as increasing the dosage of tumor vaccines, using combined vaccines consisting of mGM-CSF and human interleukin-2, or combining tumor vaccine with herpes simplex virus thymidine kinase/ganciclovir treatment.

2687 10447775 The splenocytes of vaccinated mice compared with controls produced significantly higher amounts of interferon-gamma (IFN-gamma) (P<0. 01) and interleukin-2 (IL-2) (P<0.05) and lower amounts of IL-5 (P<0. 01).
2688 10447932 In order to investigate the role of B7-1 and B7-2, the human RCC cell line, MZ1257RC, which expresses normal levels of adhesion molecules and major histocompatibility complex (MHC) class I surface antigens, was transfected with B7-1 and B7-2 expression vectors, respectively.

2693 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.
2694 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.
2695 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.
2696 10459843 This results in the synthesis of interleukin-10 (IL-10), which suppresses the formation of interferon-gamma (INF-gamma) and IL-2, and of IL-6, which suppresses T-cell responses.

2746 10496363 Peripheral blood lymphocytes from 41 normal donors were stimulated by these peptides in culture media containing 15 IU ml(-1) interleukin-2, 25 IU ml(-1) interleukin-7 and 500 IU ml(-1) granulocyte-macrophage colony-stimulating factor.
2747 10498243 Combination of CD80 and granulocyte-macrophage colony-stimulating factor coexpression by a leukemia cell vaccine: preclinical studies in a murine model recapitulating Philadelphia chromosome-positive acute lymphoblastic leukemia.
2748 10498243 We compared the efficacy of BM185 cell vaccine expressing CD80 alone or in combination with IL-2 or GM-CSF.
2749 10498243 Mice injected with viable BM185 leukemia cells modified to express CD80 and GM-CSF (BM185/CD80+GM-CSF) showed the highest leukemia rejection rates.
2750 10498243 Cell vaccines consisting of irradiated BM185/CD80+GM-CSF cells administered subcutaneously stimulated a potent cytotoxic T lymphocyte (CTL) response against parental BM185.
2751 10498243 Administration of the BM185/CD80+GM-CSF cell vaccine before intravenous challenge with parental cells caused strong inhibition of leukemia development.
2752 10498243 The immunization efficacy of the BM185/CD80+ GM-CSF cell vaccine was directly correlated with the percentage of cells expressing the transgenes.

2755 10505849 Induced immunity by expression of interleukin-2 or GM-CSF gene in murine neuroblastoma cells can generate antitumor response to established tumors.
2756 10505849 For that purpose, we transduced low immunogenic C1300 cells with interleukin-2 (IL-2), GM-CSF, or IL-4 genes.
2757 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.
2758 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.
2759 10505849 Accordingly, the inoculation of IL-2 or GM-CSF producers into immunocompetent mice generated tumor-specific acquired immunity.
2760 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.
2761 10505849 These data suggest a potential application of IL-2- or GM-CSF-producing syngeneic tumor cells for the treatment of low immunogenic neuroblastomas.

2833 10570751 The RenCa mouse renal carcinoma and the B16 mouse melanoma were used as animal tumor models, with interleukin-2 (IL-2) as a cytokine and liposomes as a depot form.
2834 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.
2835 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.

2881 10600341 We found that glutamine at an optimal concentration (0.6 mM) significantly enhanced PHA-stimulated lymphocyte proliferation as well as Th1 [interferon-gamma (IFN-gamma) and interleukin-2 (IL-2)] and Th2 cytokine (IL-4 and IL-10) production.
2882 10600341 Interestingly, addition of glutamine promoted the BCG-elicited Th1 cytokine response (IFN-gamma), but suppressed the measles-induced Th2 cytokine response (IL-10).

2901 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.
2902 10656428 Pre- and postvaccination peripheral blood mononuclear cells (PMBCs) of the eight patients positive for HLA-class I A2 allele, were incubated with the HLA-A2-CEA peptide CAP-1 and interleukin 2.

2977 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.
2978 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.

2986 10741724 Of six p53-derived peptides possessing an HLA-A24 binding motif, the p53 peptide 125-134 (p53(125-134)) was found to have a high binding capacity and induced peptide-specific CTLs from peripheral blood mononuclear cells, using peptide-pulsed autologous dendritic cells and subsequent cultivation with cytokines interleukin 2 and interleukin 7.

3027 10770624 On the contrary, when IL-7- or IL-7-IL-2-producing cells were used as stimulators, only a delay in leukemic cell overgrowth was observed, and lymphocytes were completely cleared from the cultures after day 60.
3028 10770624 IL-7 production by the different clones ranged between 11 and 36 ng/mL/10(6) cells/72 hours, whereas the highest IL-2-producing IL-7-IL-2 clone released 50 IU/mL/10(6) cells/72 hours of IL-2.
3029 10770624 Autologous and allogeneic long-term MLTCs (up to 35 days) with ST4/IL-2#A7 as the stimulator were capable of generating cytotoxic effectors equally endowed with both major histocompatibility complex (MHC) class I-unrestricted and -restricted activity against parental ST4 cells.

3068 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.
3069 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.
3070 10772979 Increased T-cell activation by vp18 was confirmed by higher numbers of both p18-specific IFN-gamma-secreting splenocytes and activated CD8(+) and CD4(+) T cells.
3071 10772979 Despite modest in vivo activation, SINp18-induced CD4(+) T cells secreted substantial amounts of IFN-gamma and IL-2, potentially contributing to sustained CD8(+) memory.
3072 10773410 In the tumor establishment model in nude mice, IL-2 and interferon-gamma (IFN-gamma) at high concentrations were detected in the sera of mice transplanted with KB/IL-2 cells.
3073 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.
3074 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.

3078 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.
3079 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).
3080 10792843 Macrophages from mice vaccinated with SP of M. habana produced enhanced levels of interleukin(IL)-2, interleukin-12 and interferon(IFN)-gamma.
3081 10811476 Because IL-12 and IL-2 have been found to have synergistic antitumoral activity, we further analyzed the biologic activity of tumor cells cotransduced by separate HSV vectors carrying genes coding for these two cytokines.

3088 10820273 These studies show that coincident expression of CD40L enhances the Th1 (IL-2 and IFN-gamma) cytokine responses, increases the expression of TNF-alpha and NO, accelerates virus clearance, and increases the anti-F and anti-G Ab responses.
3089 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.
3090 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.
3091 10838666 Generation of monocyte-derived dendritic cells from patients with renal cell cancer: modulation of their functional properties after therapy with biological response modifiers (IFN-alpha plus IL-2 and IL-12).
3092 10838666 The combination of interferon-alpha (IFN-alpha) plus interleukin (IL-2) has been accepted in the treatment of metastatic renal cell carcinoma (MRCC), whereas vaccines based on IL-12 or dendritic cells (DCs) are still being investigated.
3093 10838666 Eight and 13 MRCC patients received IL-2 plus IFN-alpha or IL-12 immunotherapy, respectively.
3094 10838666 The adherent fraction of mononuclear cells from patients' blood drawn before, during, and after immunotherapy was incubated in clinically approved culture medium supplemented with 5% autologous serum, rhu granulocyte macrophage colony-stimulating factor, and rhuIL-4 for a week.

3109 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.
3110 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.
3111 10841077 We observed that coimmunization with IL-8, gammaIP-10, and MIP-1alpha genes increased the antibody response.
3112 10841077 We also found that coinjection with IL-8, gammaIP-10, and RANTES resulted in a dramatic enhancement of T helper (Th) proliferation response.
3113 10841077 This enhancement of CTL responses observed from the coinjection with RANTES was CD8+ T cell dependent.
3114 10854647 T cell vaccination (TCV) was also associated with a decline of myelin-specific IL-2- and IFN-gamma-secreting T cells.
3115 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.
3116 10857759 After vaccination of breast cancer patients with a combination of tumour-associated antigens and biological adjuvants (IL-2 and GM-CSF), the concentration of IL-6 decreased significantly (P<0.05) to 8.1 +/- 14.6 pg/ml (n=85).
3117 10857759 Other studies have shown that oestrogen suppresses IL-6 production in oestrogen receptor positive breast cancer cells.
3118 10857759 We have demonstrated that the decrease in IL-6 associated with vaccination is related to the oestrogen receptor status of the tumours from breast cancer patients, as a decrease in IL-6 from 124.0 +/- 267.5 pg/ml (n=26) to 6.2 +/- 11.0 pg/ml (n=34) only occurs in patients with oestrogen receptor negative tumours.
3119 10857759 The IL-6 concentration in breast cancer patients with oestrogen receptor positive tumours remained unchanged (9.5 pg/ml before vaccination, and 9.3 pg/ml after vaccination).
3120 10858194 Interleukin-2 (IL-2) and gamma interferon (IFN-gamma) secretion, however, was much lower in gg-immunized than in i.m.
3121 10858194 On the other hand, C57BL mice reacted only very weakly to gg immunization, whereas elevated Ag85A-specific antibody, IL-2, and IFN-gamma responses (significantly higher than in BALB/c mice) were detected following vaccination by the i.m. route.
3122 10858194 Interleukin-2 (IL-2) and gamma interferon (IFN-gamma) secretion, however, was much lower in gg-immunized than in i.m.
3123 10858194 On the other hand, C57BL mice reacted only very weakly to gg immunization, whereas elevated Ag85A-specific antibody, IL-2, and IFN-gamma responses (significantly higher than in BALB/c mice) were detected following vaccination by the i.m. route.
3124 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.
3125 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.
3126 10866836 It has been proposed that the more aggressive liver disease observed in individuals infected with HAV in addition to chronic HBV/HCV is a result of the induction of interferon (IFN)-alpha during acute HAV infection.
3127 10866836 Alternatively, HAV may indirectly stimulate the T helper 1 (Th1)-type cytokine responses, such as interleukin (IL)-2, IFN-gamma and tumour necrosis factor (TNF)-alpha, which directly promote the antiviral CTL response.
3128 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.
3129 10870026 Many of them utilise methods of gene therapy, but follow different strategies: (1) reintroduction of the tumour suppressor p53 into a background lacking functional p53; (2) suicide gene therapy with ganciclovir and a transduced gene for herpes simplex virus thymidine kinase controlled by the thyroglobulin promoter; (3) strengthening of the antitumour immune response by expression of an adenovirus-delivered interleukin-2 (IL-2) gene; (4) induction of an immune response by DNA vaccination against the tumour marker calcitonin; (5) transduction of the thyroid sodium/iodide transporter gene to make tissues that do not accumulate iodide treatable by radioiodide therapy; (6) blocking of the expression of the oncogene c-myc by antisense oligonucleotides.

3131 10879922 Although their role in eliminating Eimeria infection remains to be completely elucidated, T cells have been implicated in parasite transport, and their activity is augmented by interferon-gamma and interleukin-2.

3135 10880017 Allogeneic vaccination was not effective in another model, against the B16F10 melanoma in C57BL/6 mice, irrespective of genetic modification with the IL-2 or granulocyte-macrophage colony-stimulating factor genes.
3136 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).
3137 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.
3138 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.
3139 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.
3140 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.
3141 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).
3142 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.
3143 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.
3144 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.
3145 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.
3146 10892997 The use of plasmids expressing interleukin-2 (IL-2) and granulocyte-macrophage colony-stimulating-factor (GM-CSF) in conjunction with pcDNA-ORF2 enhanced the antibody responses generated by pORF-2.
3147 10892998 Immunization with the JE vaccine induced T-cell activation in vivo, demonstrated by increase in the plasma levels of interleukin (IL)-2 and soluble CD8.
3148 10911917 The colorectal cancer antigen GA733 (also termed CO17-1A, KSI-4, Ep-CAM, KSA) has proved to be a useful target in passive immunotherapy with monoclonal antibody and in active immunotherapy with antiidiotypic antibodies in cancer patients.
3149 10911917 AV mEGP, only when combined with interleukin-2, significantly inhibited growth of established mEGP-positive tumors.
3150 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.
3151 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.
3152 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.
3153 10915558 LFA-3 also enhanced Th cell proliferative responses and production of interleukin (IL)-2, interferon-gamma, IL-4, and IL-10 from splenocytes.
3154 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.
3155 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.
3156 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.
3157 10918200 IL-15 is an immunostimulatory cytokine with IL-2-like activities.
3158 10918200 Significant IL-15 secretion was achieved only by the use of a modified cDNA encoding for an IL-15 pre-protein bearing the IgK light chain signal peptide.
3159 10918200 TS/A IL-15 was restored in animals depleted of CD8(+) lymphocytes or of natural killer cells and partially in CD4(+)-depleted mice.
3160 10918200 Cytolytic T lymphocyte (CTL) activity, specifically inhibited by anti-CD3 antibodies, was inducible in the splenocytes of TS/A IL-15-immunized animals by mixed lymphocyte/tumor culture (MLTC), and IFN-gamma was released in the supernatant of MLTC, mainly by CD8(+) cells.
3161 10918200 Immunohistochemistry of the TS/A IL-15 tumor area revealed the presence of an inflammatory infiltrate with predominant natural killer, macrophage, and granulocyte components and expression of IFN-gamma as a distinctive secondary cytokine.
3162 10925363 After s.c. injection of SBCC, the recently activated T cells, which were identified by their reduced expression of CD62L (L-selectin), were isolated from the draining lymph nodes, expanded with anti-CD3 and IL-2, and their cytokine response to tumor cells in vitro was analyzed.
3163 10936091 One of these viral proteins, p12(I), encoded by HTLV-I orfI, is a weak oncogene that binds the 16-kDa subunit of the vacuolar ATPase and interacts with the immature beta and gamma(c) chains of the IL-2 receptor.
3164 10944482 Retinoic acid and polyriboinosinic acid act synergistically to enhance the antibody response to tetanus toxoid during vitamin A deficiency: possible involvement of interleukin-2 receptor-beta, signal transducer and activator of transcription-1, and interferon regulatory factor-1.
3165 10944482 In VA-deficient spleens, mRNAs were low for interleukin (IL)-2 receptor-beta, interferon regulatory factor-1, and signal transducer and activator of transcription 1.
3166 10944482 Conversely, IL-12 and IL-10 mRNAs were elevated in VA deficiency and were induced by PIC and suppressed by RA.

3168 10944482 In VA-deficient spleens, mRNAs were low for interleukin (IL)-2 receptor-beta, interferon regulatory factor-1, and signal transducer and activator of transcription 1.
3169 10944482 Conversely, IL-12 and IL-10 mRNAs were elevated in VA deficiency and were induced by PIC and suppressed by RA.
3170 10948159 Consistent with the latter finding, non-ADP-ribosylating exotoxins, including an oligonucleotide DNA sequence, as well as several cytokines (interleukin-1beta [IL-1beta] fragment, IL-2, IL-12, and tumor necrosis factor alpha) and lipopolysaccharide also elicited detectable anti-DTx immunoglobulin G titers in the immunized mice.
3171 10950372 Key biological interactions between virus and host, mediated by oncogenic, immunomodulatory, and antiapoptotic viral proteins, should become the main target for new drug development. (3) Immune reconstitution with HAART and immunostimulatory cytokines such as interleukin-2 (IL-2) and IL-12, combined with drugs that downregulate the replication or gene expression of tumor-associated viruses such as Epstein-Barr virus (EBV) and human herpes virus-8 (HHV-8), possibly in combination, should remain a primary goal in the treatment of HIV-NHL.
3172 10956396 IFN-gamma, IL-12, IL-2, and IL-6 production by stimulated PBMCs was compared to unstimulated controls and the phenotype of expanded cells analyzed by flow cytometry (FACS analysis).
3173 10956396 Live BCG and most of its subcomponents (with the exception of cytosol, PstS-2 and -3) significantly enhanced IFN-gamma and IL-12 secretion, expanded CD3(-)CD56(+) cells and the non-MHC-restricted cytotoxicity against bladder tumor cells compared to unstimulated controls (all P < 0.001, t-test).
3174 10973449 In an effort to clarify this unusual conflict, we compared IL-7 along with IL-12 (Th1 control) and IL-10 (Th2 control) for its ability to induce antigen (Ag)-specific CTL and Th1- versus Th2-type immune responses using a well established DNA vaccine model.
3175 10973449 IL-7 coinjection also decreased production of Th1-type cytokine IL-2, gamma interferon, and the chemokine RANTES but increased production of the Th2-type cytokine IL-10 and the similarly biased chemokine MCP-1.
3176 10973449 In herpes simplex virus (HSV) challenge studies, IL-7 coinjection decreased the survival rate after lethal HSV type 2 (HSV-2) challenge compared with gD plasmid vaccine alone in a manner similar to IL-10 coinjection, whereas IL-12 coinjection enhanced the protection, further supporting that IL-7 drives immune responses to the Th2 type, resulting in reduced protection against HSV-2 challenge.
3177 10973449 Moreover, coinjection with human immunodeficiency virus type 1 env and gag/pol genes plus IL-12 or IL-7 cDNA enhanced Ag-specific CTLs, while coinjection with IL-10 cDNA failed to influence CTL induction.

3179 10975812 In this study, we tested the role of IL-2 in allospecific CD8+ T cell memory by analyzing the long-term survival, phenotype, and functional characteristics of IL-2-replete (IL-2+/+) and IL-2-deficient (IL-2-/-) CD8+ TCR-transgenic lymphocytes in an adoptive transfer model.
3180 10975812 We found that IL-2 is not essential for the in vivo generation, maintenance, or recall response of CD8+ memory T cells.
3181 10975812 However, IL-2 increased the size of the CD8+ memory pool if present at the time of initial T cell activation but reduced the size of the pool if present during memory maintenance by inhibiting the proliferation of CD8+ memory T cells.
3182 10975812 Thus, IL-2-based vaccine strategies or immunosuppressive regimens that target IL-2 should take into account the divergent roles of IL-2 in CD8+ T cell immunity.

3203 10992493 The percentage of survivor mice was higher in DNA-immunized mice than in animals immunized with a recombinant rPcMSP1(19)- glutathione S-transferase fusion protein administered in Freund adjuvant.
3204 10992493 The coinjection of Th1-type cytokine-expressing plasmids (gamma interferon, interleukin-2, and granulocyte-macrophage colony-stimulating factor) mostly abolished protection and boosting of MSP1(19)-specific antibodies.

3208 11004802 Addition of recombinant BCG secreting alpha antigen-fused IL-2 to peritoneal exudate cells induced IFN-gamma resulting in killing bladder cancer cells more efficiently than parental BCG did.
3209 11005833 Direct enumeration of Borrelia-reactive CD4 T cells ex vivo by using MHC class II tetramers.
3210 11005833 We characterized antigen-specific CD4(+) T cells in six patients with treatment-resistant Lyme arthritis, using an HLA-DRB1*0401 major histocompatibility complex (MHC) class II tetramer covalently loaded with OspA(164-175), an immunodominant epitope of Borrelia burgdorferi.
3211 11005833 Direct analysis of OspA-tetramer binding CD4(+) cells in patients expressing the HLA-DRB1*0401 allele revealed frequencies of between <0.005 and 0.1% in peripheral blood (n = 6), and between <0.005 and 3.1% in synovial fluid (n = 3).
3212 11005833 OspA-tetramer(+)CD4(+) cells were directly cloned at 1 cell per well and expanded by mitogen and IL-2 on allogeneic feeder cells.
3213 11005833 Clones generated from peripheral blood revealed a different pattern of responsiveness when compared with clones generated from synovial fluid, as measured by proliferation, IFN-gamma, and IL-13 secretion.
3214 11008095 Results from phase II trials have shown that the combination of interferon-alpha and interleukin-2 therapy and the infusion of dendritic cells primed with peptides of prostate specific membrane antigen are promising.
3215 11009076 CD4+ T cells contain Mycobacterium tuberculosis infection in the absence of CD8+ T cells in mice vaccinated with DNA encoding Ag85A.
3216 11009076 The contribution of CD8+ and CD4+ T cell-mediated effector functions against Mycobacterium tuberculosis infection elicited by i.m. vaccination with plasmid DNA encoding the immunodominant Ag85A antigen of M. tuberculosis was studied.
3217 11009076 In addition, Ag85A DNA-vaccinated IFN-gamma gene knockout mice produced Ag85-specific antibodies and IL-2 but died rapidly following a M. tuberculosis challenge infection.
3218 11009076 Collectively, these data support the view that IFN-gamma-producing CD4+ T cells, independently of CD8+ T cells, may mediate the protective effect of the Ag85A DNA vaccine.
3219 11023201 The main goals of this study were to examine determinants of the gene transfer by using DISC virus for squamous cancer and to evaluate the antitumoral efficacy of vaccination with tumor cells modified by DISC viruses carrying a combination of immunomodulatory genes (interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF), B7-1) in a model of squamous cell cancer (SCCVII) in C3H/HeJ mice.
3220 11023201 SCCVII cells transduced by DISC viruses (multiplicity of infection of 10) carrying the IL-2 or GM-CSF gene produced nanogram quantities of IL-2 or GM-CSF per 10(6) cells.

3228 11024117 No evidence was found for interleukin 4 (IL-4) or IL-5 production by isolated lymphocytes from children or adults.
3229 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).
3230 11035118 The proliferative response was defined as a Th response by the selective expansion of CD4(+) cells, up-regulation of CD25 and CD40L, and IL-2 and IFN-gamma expression.
3231 11039923 In contrast, all monkeys that received the DNA vaccines augmented with IL-2/Ig were infected, but demonstrated potent secondary CTL responses, stable CD4+ T cell counts, preserved virus-specific CD4+ T cell responses, low to undetectable setpoint viral loads, and no evidence of clinical disease or mortality by day 140 after challenge.
3232 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).
3233 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).
3234 11054277 Codelivery of plasmid expressing GM-CSF or IFN-alpha had no effect on cytokine mRNA expression or on B cell response.
3235 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.

3237 11055798 We have compared the therapeutic activity of IL-12 and IL-18 in mice carrying IL-2 gene-transduced syngeneic sarcoma Mc12.
3238 11055798 Murine recombinant IL-12 was capable of suppressing growth of the IL-2 gene-modified sarcoma Mc12 in syngeneic mice more efficiently than growth of the parental Mc12 sarcoma.
3239 11055798 In contrast, murine recombinant IL-18 could neither inhibit growth of the parental Mc12 sarcoma, nor suppress growth of its IL-2 gene-modified transfectant.
3240 11055798 These results suggest that although both of these cytokines are functionally related and participate in the induction of IFN gamma production as well as in cell-mediated immune cytotoxicity, in the murine sarcoma system only IL-12 is therapeutically active and exerts its therapeutic effect in concert with the IL-2 gene.
3241 11055798 Thus, intratumoral IL-2 gene transfer improves the therapeutic efficacy of IL-12; administration of recombinant IL-12 should therefore be considered as adjuvant in IL-2 gene therapy with irradiated, genetically modified tumour vaccines.

3266 11059695 In vitro coculture of spleen cells from B16/ssIL-1beta vaccinated animals and wt B16 cells induced an enhanced proliferative response, which correlated with elevated production of IL-2 and interferon-gamma.
3267 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.
3268 11075550 Stimulated PBMC expressed IL-1, IL-2, IL-4, IL-6, IL-10 and IL-12 and secreted interferon-gamma (IFN-gamma).
3269 11092043 Patients treated with repeated injections of a polyvalent melanoma vaccine (PMV), interferon-alpha-2b (IFN-alpha 2b) or interleukin-2 (IL-2) were followed during treatment duration.
3270 11092043 Before treatment, patients treated with PMV or IFN-alpha 2b had comparable low MIA concentrations, whereas most IL-2-treated patients had higher MIA levels.

3361 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.
3362 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.
3363 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.
3364 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.

3372 11155821 The disease stage and serum CA15-3, CEA and CA125 concentrations were also determined pre- and post-vaccination.
3373 11155821 The vaccine induced a significant increase in post-vaccination lymphocyte proliferative responses to AUTOC, CA15-3, CEA and CA125 but not ALLOC, compared to pre-vaccination (p < 0.05, p < 0.01, p < 0.05, p < 0.01 and p > 0.05, respectively, a paired t Test).

3412 11257383 We observed that coadministration of IL-2 and IFN-gamma cDNA resulted in enhancement of antigen-specific T cell-mediated immune responses.

3416 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.
3417 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.
3418 11267967 We have found evidence of the anti-tumor effects of 3 major lymphocyte-specific chemokines, secondary lymphoid tissue chemokine (SLC), EBI-1-ligand chemokine (ELC) and stromal cell-derived factor (SDF)-1alpha, in murine models (Meth A fibrosarcoma and HM-1 ovarian tumor).
3419 11267967 In both naive and immunized mice, tumors expressing SLC, ELC or SDF-1alpha showed delayed progression compared with control tumors.
3420 11267967 In mice immunized with tumor cells expressing 1 of these 3 chemokine genes, challenge with parental tumor cells resulted in slightly slower progression than in control mice, while in mice immunized with tumor cells transfected to co-express IL-2 or granulocyte-macrophage colony-stimulating factor (GM-CSF) as well as these chemokines, all tumors regressed.
3421 11267967 These findings show that SLC, ELC and SDF-1alpha enhance anti-tumor immunity both systemically and locally and that these chemokines may be clinically useful, especially when combined with IL-2 and GM-CSF.
3422 11267967 We have found evidence of the anti-tumor effects of 3 major lymphocyte-specific chemokines, secondary lymphoid tissue chemokine (SLC), EBI-1-ligand chemokine (ELC) and stromal cell-derived factor (SDF)-1alpha, in murine models (Meth A fibrosarcoma and HM-1 ovarian tumor).

3426 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.
3427 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.
3428 11269272 In sharp contrast, vaccination with irradiated cercariae induced IFN-gamma and IL-2 responses in the skin within 24 h.
3429 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.
3430 11269272 Analysis of the CD4/CD8 ratio showed a significant decrease in the skin following vaccination suggesting an increase in CD8+ cells.
3431 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.
3432 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.
3433 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.

3437 11282983 Using mAb to trigger CD2 and CD28 co-stimulatory molecules, we found that such dual co-stimulation of LT-T induces profound and sustained responses including CD25 expression, IL-2 secretion and proliferation.
3438 11282983 Blocking studies demonstrated that optimal proliferation was critically dependent on co-stimulation via CD2 and CD28 engaged by their ligands on the APC.
3439 11282986 Differential effect of CD8(+) and CD8(-) dendritic cells in the stimulation of secondary CD4(+) T cells.
3440 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.
3441 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.
3442 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.
3443 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.
3444 11292314 Chicken interleukin 2 (chIL-2) has low, but significant, homology to both mammalian IL-2 and mammalian IL-15.
3445 11292314 It was found that Asp17 is a critical N terminal contact site for binding to the putative chIL-2 receptor, which is similar to results obtained for mammalian IL-2 and IL-15.

3448 11292722 Injection of Ag85 DNA-primed mice with 30 to 100 microg of purified Ag85 protein in adjuvant increased the interleukin-2 and gamma interferon (IFN-gamma) response in spleen two- to fourfold.
3449 11292752 Nasal and IPP immunization groups had increased cytokine expression of interleukin-2 (IL-2) and IL-5 and differed from each other for IL-6.
3450 11294562 Thus, for the first time, we show monoclonal or oligoclonal expansion of primary human CD4- peripheral blood mononuclear cells (PBMC) in vitro in response to nominal protein antigen without manipulations utilizing exogenous IL-2.
3451 11300487 More specifically, coimmunization with interleukin (IL)-2 cDNA construct resulted in a significant enhancement of PSA-specific antibody responses in both mice and macaque models.
3452 11300487 In mice, the groups coimmunized with IL-2, IL-12, or IL-18 showed a dramatic increase in T helper cell proliferation over the results with pCPSA alone.

3455 11305184 Promising treatment options are melanoma vaccines to obtain an efficient immunoresponse, the combination of chemotherapy with Interleukin (IL)-2 and Interferon alfa (IFN-alpha) as a way of improving response rates and survival.
3456 11349047 Heat-killed Brucella abortus (HBa) has been proposed as a carrier for therapeutic vaccines for individuals with immunodeficiency, due to its abilities to induce interleukin-2 (IL-2) and gamma interferon (IFN-gamma) in both CD4(+) and CD8(+) T cells and to upregulate antigen-presenting cell functions (including IL-12 production).
3457 11349047 Among purified T cells, macrophage inflammatory protein 1alpha and 1beta (MIP-1alpha and MIP-1beta, respectively) secretion was observed primarily in human CD8(+) T cells.
3458 11349047 The majority of beta-chemokine-producing CD8(+) T cells also produced IFN-gamma following HBa stimulation, as determined by triple-color intracellular staining.
3459 11349047 A significant number of CD8(+) T cells contained stored MIP-1beta that was released after HBa stimulation.
3460 11349047 Both HBa and LPS-Ba stimulated high levels of MIP-1alpha and MIP-1beta production in elutriated monocytes and even higher levels in macrophages.
3461 11349067 Influence of vector-encoded cytokines on anti-Salmonella immunity: divergent effects of interleukin-2 and tumor necrosis factor alpha.

3470 11355944 Stimulation of cells from patients in clinical remission with anti-CD3(+)rIL-2 increased the proportion of CD8(+)zeta(+)cells and normalized IL-2 production levels.
3471 11359364 This state is due to the binding of HIV envelope glycoprotein moieties to CD4 molecules and chemokine receptors.
3472 11359364 This effect is exemplified by diminished production of interleukin-2 (IL-2) and interferon-gamma and reduced expression of IL-2 receptor by CD4 helper cells of HIV patients.
3473 11369873 Humoral and CD4(+) T helper (Th) cell responses to the hepatitis C virus non-structural 3 (NS3) protein: NS3 primes Th1-like responses more effectively as a DNA-based immunogen than as a recombinant protein.
3474 11369873 The non-structural 3 (NS3) protein is one of the most conserved proteins of hepatitis C virus, and T helper 1 (Th1)-like responses to NS3 in humans correlate with clearance of infection.
3475 11369873 Inbred mice were immunized twice in regenerating tibialis anterior (TA) muscles with either plasmid DNA or recombinant NS3 (rNS3).
3476 11369873 NS3-specific CD4(+) T cell responses in DNA-immunized mice peaked at day 13, as measured by proliferation and IL-2 and IFN-gamma production.
3477 11369873 CD4(+) T cell responses in these mice showed peaks of IL-2 response at day 3 and IL-6 and IFN-gamma responses at day 6.
3478 11369873 However, as a DNA immunogen, NS3 elicits stronger Th1-like immune responses, whereas rNS3 primes a mixed Th1/Th2-like response regardless of the route, dose or adjuvant.

3485 11370250 Immunological studies showed that both Th1 and Th2 cell responses could be demonstrated in lymph nodes from VL patients as evidenced by the presence of messenger ribonucleic acid for interleukin (IL)-10, interferon gamma and IL-2.
3486 11370250 Treatment of peripheral blood mononuclear cells from VL patients with IL-12 was found to drive the immune response toward a Th1 type response with the production of interferon gamma, indicating a potential therapeutic role for IL-12.

3490 11380416 In a pilot study, we tested the feasibility and safety of combined immunotherapy consisting of adoptive transfer of autologous tumour-specific T cells, low-dose interleukin 2 (IL-2) and a cellular vaccine of CD40-activated plasma cell leukaemia (PCL) cells in a patient who failed tandem repeat stem cell transplantation and idiotype vaccination.
3491 11380416 CD40-activated PCL cells for vaccination were similarly generated ex vivo by co-culture with CD40 ligand transfectants.
3492 11380416 We demonstrated the safety and feasibility in combining autologous tumour-specific T-cell therapy with low-dose IL-2 and that clinical trials based on the use of CD40-activated autologous tumour cell vaccines are warranted in patients with CD40-activated autologous tumour cells, either as a vaccine or for ex vivo stimulation of autologous T cells.

3503 11395193 During the blockade of the tumor growth, the CTL response was maintained for at least approximately 6 weeks, and the mice secreted Th1 type cytokines such as IL-2 and IFN-gamma.
3504 11399230 Modulation of cellular responses by plasmid CD40L: CD40L plasmid vectors enhance antigen-specific helper T cell type 1 CD4+ T cell-mediated protective immunity against herpes simplex virus type 2 in vivo.
3505 11399230 The costimulatory molecule CD40, expressed on antigen-presenting cells, is thought to interact with CD40 ligand (CD40L) expressed on activated CD4(+) or CD8(+) T cells to further drive interleukin-2 receptor (IL-2R) expression and antigen-specific T cell expansion necessary for both class II and class I responses.
3506 11399230 To compare the specific roles of these two costimulatory molecules in immune induction in a herpes simplex virus (HSV) model, we constructed plasmid DNAs expressing CD40 and CD40L, coimmunized these molecules with a gD plasmid vaccine, and then analyzed immune modulatory effects as well as protection against lethal HSV-2 challenge.
3507 11399230 CD40L also enhanced Th cell proliferative responses and production of Th1-type cytokines (IL-2 and IFN-gamma) and beta-chemokines (RANTES and MIP-1alpha) from splenocytes.
3508 11399230 When animals were challenged with a lethal dose of HSV-2, CD40L-coimmunized animals exhibited a significantly enhanced survival rate, as compared with CD40 coinjection or gD DNA vaccine alone.
3509 11399230 CD40L also promoted migration of CD4(+) T cells into the muscle sites.
3510 11399230 These studies demonstrate that CD40L can play an important role in protective antigen-specific immunity in a gene-based model system through increased expansion of the CD4(+) Th1 T cell subset in vivo.

3518 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.
3519 11434720 Specifically, anergy is characterized by lack of activation of lck, ZAP 70, Ras, ERK, JNK, AP-1, and NF-AT.
3520 11434720 This second messenger upregulates the cyclin-dependent kinase (cdk) inhibitor p27kip1, sequestering cyclin D2-cdk4, and cyclin E/cdk2 complexes and preventing progression of T cells through the G1 restriction point of the cell cycle.
3521 11434720 In contrast, costimulation through CD28 prevents p27kip1 accumulation by decreasing the levels of intracellular cAMP and promotes p27kip1 down-regulation due to direct degradation of the protein via the ubiquitin-proteasome pathway.
3522 11434720 Subsequent autocrine action of IL-2 leads to further degradation of p27kip1 and entry into S phase.
3523 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.
3524 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.
3525 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.
3526 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.
3527 11457533 Subcutaneous but not oral administration in BALB/c mice of the HS-PEC induced high amounts of IFN-gamma and IL-2 but low quantities of IL-4 suggesting a combined Th1/Th2 cellular immune response.
3528 11457549 Murine interleukin-2 (IL-2) and granulocyte-macrophage colony-stimulating factor (GM-CSF) were chosen for their potential ability to enhance the humoral and cellular immune responses involved in protection against BVDV.
3529 11459172 In order to construct an immunogenic cellular vaccine, we transduced three HLA-A*0201 human melanoma lines, selected for expression of classes I and II HLA, adhesion molecules and the T cell-defined melanoma antigens Melan/MART-1, gp100 and tyrosinase, with both interleukin-2 (IL-2) and B7-1 genes by the use of a polycistronic retroviral vector.
3530 11459172 From a functional point of view, expression of both genes in melanoma lines: (1) improved the response of anti-melanoma cytotoxic T lymphocytes (CTL) over singly transduced or untransduced melanoma cells when subthreshold levels of MHC-peptide complexes were expressed by melanoma cells; (2) conferred a distinct advantage in the ability to stimulate cytotoxicity and interferon-gamma release by autologous and/or HLA-A*0201-compatible allogeneic lymphocytes; (3) allowed the generation of a high number of specific CTL by in vitro stimulation of lymphocytes of HLA-A*0201-melanoma patients.
3531 11477458 Transgenic expression of CD40L and interleukin-2 induces an autologous antitumor immune response in patients with non-Hodgkin's lymphoma.
3532 11477458 To stimulate NHL-specific immune responses, we attempted to transfer the human CD40 ligand (hCD40L) gene to B-NHL cells and enhance their co-stimulatory potential.
3533 11477458 Expression of transgenic human CD40L on these CD40-positive cells was in turn associated with up-regulation of other co-stimulatory molecules including B7-1/-2.
3534 11477458 These findings suggest that the combination of CD40L and IL2 gene-modified B-NHL cells will induce a cytotoxic immune response in vivo directed against unmodified tumor cells.

3539 11485354 Additionally, bromelain did not affect TCR and CD28-induced proliferation of highly purified CD4+ T cells, but did inhibit IL-2 production by these cells.
3540 11500411 Characterization of the cellular immune response induced against the protective amino-terminal fragment reveals production of gamma interferon and interleukin-2, but not interleukin-4, suggesting a Th1-like profile.
3541 11500418 A novel strain, Origami(DE3), of Escherichia coli with mutations in the glutathione and thioredoxin reductase genes yielded 60% more soluble PvMSP-1 p42 than the conventional E. coli BL21(DE3) strain.
3542 11500418 Lymphocytes from animals in all the PvMSP-1 p42-immunized groups showed proliferative responses upon stimulation with PvMSP-1 p42; the cytokines interleukin 2 (IL-2), gamma interferon, IL-4, and IL-10 were detected in the culture supernatants.
3543 11507070 We demonstrate that a mouse-human chimeric anti-ganglioside GD2-interleukin (IL)-2 fusion protein (ch14.18-IL2) substantially amplifies tumor-protective immunity against murine melanoma induced by an autologous oral DNA vaccine containing the murine ubiquitin gene fused to murine melanoma peptide epitopes gp100(25-35) and TRP-2(181-188).
3544 11507070 The tumor-protective immunity was mediated by MHC class I antigen- restricted CD8(+) T cells together with CD4(+) T cell help, which was required only for tumor cell killing in the effector phase of the immune response.
3545 11507070 The immunological mechanisms involved in this antitumor effect were suggested by a decisively increased secretion of tumor necrosis factor alpha TNFTnTNa and IFN-gamma from CD4(+) and CD8(+) T cells and a markedly up-regulated expression on CD8(+) T cells of high-affinity IL-2 receptor alpha chain (CD25), costimulatory molecule CD28, and adhesion molecule lymphocyte function-associated antigen-2 (LFA-2/CD2).
3546 11507070 We demonstrate that a mouse-human chimeric anti-ganglioside GD2-interleukin (IL)-2 fusion protein (ch14.18-IL2) substantially amplifies tumor-protective immunity against murine melanoma induced by an autologous oral DNA vaccine containing the murine ubiquitin gene fused to murine melanoma peptide epitopes gp100(25-35) and TRP-2(181-188).

3548 11507070 The immunological mechanisms involved in this antitumor effect were suggested by a decisively increased secretion of tumor necrosis factor alpha TNFTnTNa and IFN-gamma from CD4(+) and CD8(+) T cells and a markedly up-regulated expression on CD8(+) T cells of high-affinity IL-2 receptor alpha chain (CD25), costimulatory molecule CD28, and adhesion molecule lymphocyte function-associated antigen-2 (LFA-2/CD2).
3549 11515819 An in vitro assay system was developed to assess the potency of the human innate immune system by measurement of IL-12, IL-18, IL-10 and IFNgamma in the supernatants of bacillus Calmette-Guerin cell wall skeleton (BCG-CWS)-stimulated blood samples.
3550 11515819 The following results were deduced from analyses of BCG-CWS-stimulated blood samples of lung cancer patients with reference to normal subjects. (1) The levels of production of IFNgamma and IL-10 by lymphocytes were decreased. (2) IL-12 p40 production by monocytes/Mphi was upregulated, while that of IL-10 was downregulated. (3) IL-18 was detected in all patients in a range similar to normal subjects. (4) Responses of lymphocytes to IL-2 and IL- 18 in terms of IFNgamma production were diminished. (5) The upregulated IL-12 levels were recovered to within the normal range in most patients after tumor resection. (6) Male patients showed more severe suppression of IL-12/IL-18-mediated IFNgamma production than female patients.
3551 11515819 Thus, the lesser IFNgamma production observed in patients' blood with high IL-12 p40 levels in response to BCG-CWS may reflect the production of p40 dimers or IL-23 instead of p70, or the presence of some unknown pathways to prohibit the interface between the innate and acquired immune systems.
3552 11517429 Among those with severe clinical disease, Env-stimulated IL-2 reactivity in PBMC was negatively correlated with HIV-1 RNA copy numbers in plasma at enrollment and was positively correlated with CD4 T cell percentages 1 year later.
3553 11522187 Coadministration of SF-2 rgp120 vaccine with vCP205 vaccine enhanced lymphocyte proliferation in response to HIV-1 envelope glycoprotein and broadened the envelope-stimulated cytokine secretion pattern, so that it consisted of both Th1 and Th2 cytokines compared with only interferon gamma (IFN-gamma) after vCP205 vaccine given alone.
3554 11522187 There was a possible association between HIV-1 envelope glycoprotein-stimulated interleukin 2 secretion and CD8(+) CTLs against HIV-1 envelope glycoprotein, and an inverse relation between lymphocyte proliferation and CTLs against HIV-1 Gag antigens.
3555 11522639 Autologous mononuclear cells were cocultured with DCs in the presence of low-dose interleukin (IL)-2 and IL-7 and were restimulated weekly with new DCs.
3556 11522639 High levels of IL-12 and IFN-gamma could be detected in the supernatants, indicating a T-helper type 1-type immune response.
3557 11527813 In addition, LTA inhibited IL-2 detection by enzyme-linked immunosorbent assay (ELISA) and blocked the proliferative response of an IL-2-dependent T-cell line to soluble IL-2.
3558 11527813 Further studies using ELISA demonstrated that LTA blocks IL-2 detection and function by binding directly to IL-2.
3559 11527813 In addition, LTA inhibited IL-2 detection by enzyme-linked immunosorbent assay (ELISA) and blocked the proliferative response of an IL-2-dependent T-cell line to soluble IL-2.
3560 11527813 Further studies using ELISA demonstrated that LTA blocks IL-2 detection and function by binding directly to IL-2.
3561 11528593 Hib-CRM(197) induced PS and CRM(197) antibodies, vigorous T cell recall responses, and production of cytokines, including interleukin (IL)-2, IL-5, IL-10, and interferon-gamma.
3562 11528593 Correlations were also found between IL-2 and IL-5 and IgA PS antibody levels.
3563 11528593 Hib-CRM(197) induced PS and CRM(197) antibodies, vigorous T cell recall responses, and production of cytokines, including interleukin (IL)-2, IL-5, IL-10, and interferon-gamma.
3564 11528593 Correlations were also found between IL-2 and IL-5 and IgA PS antibody levels.
3565 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.
3566 11535317 Systemic co-transfer of both CCR7 ligands enhanced serum gB-specific IgG Ab but failed to elicit enhancement of distal mucosal IgA responses.
3567 11535317 CCR7 ligands also enhanced T cell-mediated immunity as measured by CD4+ T helper cell proliferation and CD8+ T cell-mediated CTL activity.
3568 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).
3569 11535343 To better characterize the cytokine response to measles virus vaccine, we examined the levels of IL-2, IL-4, IL-5, IL-10, IL-12 and gamma-interferon (gamma-IFN) in measles virus-stimulated peripheral blood mononuclear cells from 18 donors before and 2 weeks after vaccination.
3570 11535343 The majority of donors in both groups did not exhibit an increase in measles specific IL-4 or IL-10 mRNA after vaccination.
3571 11536152 T cells rendered anergic lost IL-2 production but produced IFN-gamma and IL-10 upon stimulation.
3572 11536152 Autoreactive CD4(+) T cell clones specific for topoisomerase I derived from a patient with scleroderma were also rendered anergic after co-culture with topoisomerase I-pulsed autologous pDC2,resulting in failure to proliferate or provide help to B cells.
3573 11544306 A panel of E2 DNA vaccines were constructed, and their vaccination efficacy was ranked as E2 > tyrosine kinase-deficient ErbB-2 (E2A) > full-length ErbB-2 targeted to the cytoplasm (cytE2) > tyrosine kinase-deficient cytE2 (cytE2A).
3574 11544306 Covaccination with cytE2A and GM-CSF or IL-2 DNA resulted in equivalent anti-tumor activity as E2.
3575 11544306 ErbB-2-specific CTL were detected in mice immunized with cytE2A and GM-CSF and have rejected tumor challenge.
3576 11544306 Depletion of CD8, but not CD4 T cells reduced anti-tumor immunity, indicating CTL as the effector cells.
3577 11550123 Strong induction of Th1-type immune responses included high levels of antigen-specific elaboration of the Th1-type cytokines interferon-gamma and interleukin-2 and beta-chemokines RANTES (regulated upon activation, normal T cell-expressed and secreted) and macrophage inflammatory protein-1beta.
3578 11550123 Dramatic infiltration of CD4 and CD8 T cells and macrophages also was observed at the muscle injection site.
3579 11558546 Reverse transcriptase polymerase chain reaction (RT-PCR) analysis revealed that T cell lines derived from each animal expressed relatively high levels of interferon (IFN)-gamma mRNA, low levels of interleukin (IL)-2, IL-10, and tumor necrosis factor (TNF)-alpha mRNAs, but no detectable level of IL-4 mRNA.
3580 11565958 We have previously demonstrated in a murine lung metastasis model that local sublethal radiation of tumors can synergistically enhance their sensitivity to immunotherapy with either systemic high-dose interleukin-2 (IL-2) or vaccination with autologous tumor cells expressing IL-2, interferon (IFN)-gamma and granulocyte-macrophage colony-stimulating factor (GM-CSF).
3581 11567773 Adjuvant effects of IL-1beta, IL-2, IL-8, IL-15, IFN-alpha, IFN-gamma TGF-beta4 and lymphotactin on DNA vaccination against Eimeria acervulina.
3582 11567773 Eight chicken cytokine genes (IL-1beta, IL-2, IL-8, IL-15, IFN-alpha, IFN-gamma, TGF-beta4, lymphotactin) were evaluated for their adjuvant effect on a suboptimal dose of an Eimeria DNA vaccine carrying the 3-1E parasite gene (pcDNA3-1E).
3583 11567773 IFN-alpha (1 microg) or 10 microg of lymphotactin expressing plasmids, when given simultaneously with the pcDNA3-1E vaccine, significantly protected against body weight loss induced by E. acervulina.
3584 11567773 Parasite replication was significantly reduced in chickens given the pcDNA3-1E vaccine along with 10 microg of the IL-8, lymphotactin, IFN-gamma, IL-15, TGF-beta4, or IL-1beta plasmids compared with chickens given the pcDNA3-1E vaccine alone.
3585 11567773 Flow cytometric analysis of duodenum intraepithelial lymphocytes showed chickens that received the pcDNA3-1E vaccine simultaneously with the IL-8 or IL-15 genes had significantly increased CD3+ cells compared with vaccination using pcDNA3-1E alone or in combination with the other cytokine genes tested.
3586 11567773 Adjuvant effects of IL-1beta, IL-2, IL-8, IL-15, IFN-alpha, IFN-gamma TGF-beta4 and lymphotactin on DNA vaccination against Eimeria acervulina.
3587 11567773 Eight chicken cytokine genes (IL-1beta, IL-2, IL-8, IL-15, IFN-alpha, IFN-gamma, TGF-beta4, lymphotactin) were evaluated for their adjuvant effect on a suboptimal dose of an Eimeria DNA vaccine carrying the 3-1E parasite gene (pcDNA3-1E).
3588 11567773 IFN-alpha (1 microg) or 10 microg of lymphotactin expressing plasmids, when given simultaneously with the pcDNA3-1E vaccine, significantly protected against body weight loss induced by E. acervulina.
3589 11567773 Parasite replication was significantly reduced in chickens given the pcDNA3-1E vaccine along with 10 microg of the IL-8, lymphotactin, IFN-gamma, IL-15, TGF-beta4, or IL-1beta plasmids compared with chickens given the pcDNA3-1E vaccine alone.
3590 11567773 Flow cytometric analysis of duodenum intraepithelial lymphocytes showed chickens that received the pcDNA3-1E vaccine simultaneously with the IL-8 or IL-15 genes had significantly increased CD3+ cells compared with vaccination using pcDNA3-1E alone or in combination with the other cytokine genes tested.
3591 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.
3592 11576883 The in vivo response to standard hepatitis B booster vaccine and in vitro proliferation and release of interleukin-2 (IL-2), IL-6, tumor necrosis factor-alpha, and interferon-gamma from stimulated lymphocytes were not different between the groups.
3593 11576883 In contrast to clinical immune effects, paricalcitol increased serum calcium levels and decreased PTH and bone alkaline phosphatase levels (all P < 0.05).
3594 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.
3595 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.
3596 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.
3597 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.
3598 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.
3599 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.
3600 11591784 A dual-function DNA vaccine encoding carcinoembryonic antigen and CD40 ligand trimer induces T cell-mediated protective immunity against colon cancer in carcinoembryonic antigen-transgenic mice.
3601 11591784 A carcinoembryonic Ag (CEA)-based DNA vaccine encoding both CEA and CD40 ligand trimer achieved effective tumor-protective immunity against murine colon carcinoma in CEA-transgenic mice by activating both naive T cells and dendritic cells.
3602 11591784 Peripheral T cell tolerance to CEA was broken in a prophylactic model by this novel, dual-function DNA vaccine, whose efficacy was further enhanced by boosts with a recombinant Ab-IL-2 fusion protein (huKS1/4-IL-2).
3603 11591784 Second, specific activation of dendritic cells was indicated by their marked up-regulation in expression of costimulatory molecules B7.1 (CD80), B7.2 (CD86), and ICAM-1.
3604 11591784 Third, a decisive increase over control values was observed in both MHC class I Ag-restricted cytotoxicity of CTLs from successfully vaccinated mice and secretion of proinflammatory cytokines IFN-gamma and IL-12.
3605 11591784 Fourth, activation of CTLs was augmented, as indicated by up-regulation of activity markers LFA-1, CD25, CD28, and CD69.
3606 11591784 Taken together, these results suggest that a dual-function DNA vaccine encoding CEA and CD40 ligand trimer combined with tumor-targeted IL-2 may be a promising strategy for the rational development of DNA-based cancer vaccines for future clinical applications.

3642 11672928 In this study, in order to selectively protect T cells from dexamethasone (DEX)-induced apoptosis we constructed a fusion protein (anti-CD3sFv-IL-2) in which anti-CD3 single-chain Fv (sFv), the smallest unit of antibody recognizing the CD3 epsilon moiety of the T-cell receptor (TCR), was covalently linked to murine interleukin-2 (IL-2).
3643 11672928 The levels of bcl-2 gene expression were significantly increased in DEX-treated T cells in the presence of the anti-CD3sFv-IL-2 protein.

3646 11676280 In murine models, the combination of mAbs with recombinant cytokines, such as IL-2, IL-12, or GM-CSF, can augment the immunologic effect of the mAbs by activating effector cell functions.
3647 11679156 Furthermore, IgG2 directed against Gag proteins was significantly associated with HIV-1 p24-specific Th1 cell production of interferon gamma and interleukin 2.
3648 11683575 Peripheral blood mononuclear cells stimulated with BGG or OVA expressed IL-2Ralpha chain but not IL-2 mRNA, consistent with T cell anergy.
3649 11691814 Here we describe a novel RCC vaccine strategy that allows for the concomitant delivery of dual immune activators: G250, a widely expressed RCC associated antigen; and granulocyte/macrophage-colony stimulating factor (GM-CSF), an immunomodulatory factor for antigen-presenting cells.
3650 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.
3651 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.
3652 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).
3653 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.
3654 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.

3661 11698440 CD40 ligand promotes priming of fully potent antitumor CD4(+) T cells in draining lymph nodes in the presence of apoptotic tumor cells.
3662 11698440 It has been demonstrated that interactions of CD40-CD40 ligand can replace CD4(+) T cell help and enable dendritic cells to prime cytotoxic T cells.

3689 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.
3690 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.

3779 11867164 MAP1-specific responses were predominantly restricted to cluster of differentiation four antigen positive T cells (CD4+ T cells).
3780 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.
3781 11867164 CD4+ T cell clones specific for MAP1 were generated.

3785 11881495 In the course of the vaccinal process the restoration of the initially inhibited characteristics (the production of TNF-alpha and IL-2) to normal values were shown to occur, which was indicative of the fact that the reserve capacities of immunocompetent cells were retained in these patients.
3786 11884558 (i) VV-NP118 induced potent and long-lasting CD8 and CD4 T-cell responses to the vector; at the peak of the response (approximately 1 week), there were approximately 10(7) VV-specific CD8 T cells (25% of the CD8 T cells) and approximately 10(6) VV-specific CD4 T cells (approximately 5% of the CD4 T cells) in the spleen.
3787 11884558 These numbers decreased to approximately 5 x 10(5) CD8 T cells (approximately 5% frequency) and approximately 10(5) CD4 T cells (approximately 0.5% frequency), respectively, by day 30 and were then stably maintained at these levels for >300 days.
3788 11884558 (ii) VV-specific CD8 and CD4 T cells were capable of producing gamma interferon (IFN-gamma), tumor necrosis factor alpha (TNF-alpha), and interleukin-2; all cells were able to make IFN-gamma, a subset produced both IFN-gamma and TNF-alpha, and another subset produced all three cytokines.
3789 11890524 Tx-CsA-treatment abrogated the IBDV-induced inflammatory response and significantly (P < 0.05) reduced the incidence of apoptotic bursa cells and the expression of cytokines such as interleukin 2 (IL-2) and interferon-gamma (IFN-gamma) in comparison to T cell-intact birds.
3790 11890524 T cell-released IL-2 and IFN-gamma may have mediated the induction of inflammation and cell death in T cell-intact birds.
3791 11890524 Tx-CsA-treatment abrogated the IBDV-induced inflammatory response and significantly (P < 0.05) reduced the incidence of apoptotic bursa cells and the expression of cytokines such as interleukin 2 (IL-2) and interferon-gamma (IFN-gamma) in comparison to T cell-intact birds.
3792 11890524 T cell-released IL-2 and IFN-gamma may have mediated the induction of inflammation and cell death in T cell-intact birds.
3793 11895976 Similarly, additional mycobacterial antigen delivered directly to the lungs by aerosol infection with viable M. tuberculosis mixed with heat-killed Mycobacterium tuberculosis (1:1) also did not reduce the bacillary load but caused increased expression of tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6), which was associated with larger granulomas in the lungs.
3794 11895976 When M. tuberculosis-infected mice were treated with recombinant BCG that secreted cytokines shown to reduce disease in a preinfection vaccine model, the BCG secreting TNF-alpha, and to a lesser extent, IL-2 and gamma interferon (IFN-gamma), caused a significant increase in granuloma size in the lungs.
3795 11899386 Expansion of HER2/neu-specific T cells ex vivo following immunization with a HER2/neu peptide-based vaccine.
3796 11899386 Transgenic mice overexpressing rat neu in mammary tissue develop malignancy, histologically similar to human HER2/neu-overexpressing breast cancer.
3797 11899386 In addition, cytokines, such as interleukin-12, when added during ex vivo culturing along with interleukin-2 can selectively expand antigen-specific T-cells.
3798 11899386 Interleukin-12 also enhances antigen-specific functional measurements such as interferon-gamma and tumor necrosis factor-alpha release.
3799 11899386 Refinements in ex vivo expansion techniques may greatly improve the feasibility of tumor-antigen T-cell-based therapy for the treatment of advanced-stage HER2/neu-overexpressing breast malignancy.

3843 11911421 This review will discuss current anti-cancer immunotherapy; interleukin-2 therapy, tumor vaccine secreting Granulocyte macrophage-colony stimulating factor, dendritic cells fused with tumor cells, and CD40 ligand immunotherapy.
3844 11911421 Moreover, we introduce our two kinds of CD40 ligand immuno-genetherapy; (1) oral CD40 ligand gene therapy against lymphoma using attenuated Salmonella typhimurium (published in BLOOD 2000), (2) cancer vaccine transfected with CD40 ligand ex vivo for neuroblastoma (unpublished).
3845 11918082 We have previously reported that immunization of mice with melanoma cells transfected to secrete the superantigen, Staphylococcal enterotoxin A (SEA), increased the production of antibodies to the B700 melanoma antigen, stimulated the production of endogenous interleukin 2 (IL-2), activated the expression of CD4, CD8 and CD25 T cell markers and enhanced NK cell activity.
3846 11920589 Peptide-specific CD8+ T-cell evolution in vivo: response to peptide vaccination with Melan-A/MART-1.
3847 11920589 We have longitudinally followed CD8+ T-cell responses in 3 melanoma patients who were immunized with peptides derived from Melan-A/MART-1.
3848 11920589 At least in a single patient, T cells binding to the AAGIGILTV epitope were detected in naive, precursor (CD45RA+/CCR7+) CD8+ T cells, and CD8+ T cells binding to the analog ELAGIGILTV peptide were identified in the terminally differentiated (CD45RA+/CCR7-) T-cell subset.
3849 11920589 The TCR repertoire reactive with Melan-A/MART-1 peptide epitopes was broadened during vaccination and exhibited a different profile of cytokine release after specific stimulation: tetramer-binding T cells from 2/3 patients secreted granulocyte/macrophage colony-stimulating factor (GM-CSF) and interferon-gamma but not interleukin-2 (IL-2) in response to Melan-A/MART-1 peptides.
3850 11920816 Tumor necrosis factor-alpha (TNF-alpha) and TNF-beta expression was detected in all samples by PCR and in < 50% of samples by immunostaining.
3851 11920816 Interleukin-2 (IL-2) and IL-4 expression was detected in a few samples by immunostaining but was not detectable by PCR.
3852 11920816 We found greater expression of TNF-alpha and IL-4 in DHF than in dengue fever or other (non-dengue) febrile illnesses.

3857 11943331 Vaccination with ST-CFP/DEAE-dextran induced high levels of interleukin-2 (IL-2) but low levels of interferon-gamma (IFN-gamma) from whole-blood cultures stimulated with M. tuberculosis ST-CFP in comparison with the strong IFN-gamma and IL-2 responses induced after vaccination with BCG.
3858 11943331 Vaccination with ST-CFP/beads induced a weak IgG1-biased antibody response but no IFN-gamma or IL-2 response.
3859 11943331 Vaccination with ST-CFP/DEAE-dextran induced high levels of interleukin-2 (IL-2) but low levels of interferon-gamma (IFN-gamma) from whole-blood cultures stimulated with M. tuberculosis ST-CFP in comparison with the strong IFN-gamma and IL-2 responses induced after vaccination with BCG.
3860 11943331 Vaccination with ST-CFP/beads induced a weak IgG1-biased antibody response but no IFN-gamma or IL-2 response.
3861 11947928 In our established model of systemic tolerance to gliadin, induced by its nasal administration, we found a reduced production of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) upon administration of gliadin alone.
3862 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.
3863 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.
3864 11953389 Antibodies to the encoded BLS included immunoglobulin G1 (IgG1) IgG2a, IgG2b, IgG3, and IgM isotypes.
3865 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.
3866 11953411 Immunization of C3H/He mice with an Ii-LLO 215-226 plasmid induced specific interferon-gamma- and interleukin 2-producing Th cells and conferred significant protective immunity against listerial infection.

3868 11964715 IL-10 initiates anergy in T cells by blocking tyrosine phosphorylation of CD28 and inhibiting the CD28 co-stimulatory signal.
3869 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).
3870 11973635 Lymphotactin cotransfection enhances the therapeutic efficacy of dendritic cells genetically modified with melanoma antigen gp100.
3871 11973635 In this study, Lptn and/or melanoma-associated antigen gp100 were transfected into mouse bone marrow-derived DC, which were used as vaccines in B16 melanoma model.
3872 11973635 Immunization of C57BL/6 mice with DC adenovirally cotransfected with Lptn and gp100 (Lptn/gp100-DC) could enhance the cytotoxicities of CTL and NK cells, increase the production of IL-2 and interferon-gamma significantly, as compared with immunization with gp100-DC, Lptn-DC, LacZ-DC, DC or PBS counterparts.
3873 11973635 In vivo depletion analysis demonstrated that CD8(+) T cells are the predominant T cell subset responsible for the antitumor effect of Lptn/gp100-DC and CD4(+) T cells were necessary in the induction phase of tumor rejection, while NK cells were less important although they participated in the antitumor response either in the induction phase or in the effector phase.
3874 11978140 Biological response modifier therapies that are in current or future investigational trials include topical tazarotene, pegylated interferon, interleukin-2, and interleukin-12.
3875 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.
3876 11985784 We developed a tumor vaccine consisting of fixed hepatocellular carcinoma (HCC) cells/tissue fragments, biodegradable microparticles encapsulating granulocyte-macrophage-colony stimulating factor and interleukin-2, and an adjuvant.
3877 11994441 Furthermore, CD8(+) and CD4(+) splenocyte fractions from treated groups secreted increased IFN-gamma and IL-2 in response to tumor cells in vitro.
3878 12007887 Distinct T (CD4+, CD8+, gammadelta-TCR+) and B (CD21+, CD45R+) lymphocyte staining patterns were observed within and around follicles of the rectal mucosa.
3879 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.
3880 12009273 To test the effect of co-expression of immunomodulatory molecules, together with target antigen, two recombinant Streptococcus gordonii strains were constructed which secreted either murine interleukin-2 (IL-2) or interferon-gamma (IFN-gamma) in addition to a surface anchored test antigen (the conserved C-repeat region (CRR) of the M6 protein of Streptococcus pyogenes).
3881 12009273 The secretion of functional cytokines by S. gordonii was achieved by in-frame fusion of sequences encoding mature IL-2 or IFN-gamma to the sequences encoding the leader signal of the M6 protein.
3882 12009273 To test the effect of co-expression of immunomodulatory molecules, together with target antigen, two recombinant Streptococcus gordonii strains were constructed which secreted either murine interleukin-2 (IL-2) or interferon-gamma (IFN-gamma) in addition to a surface anchored test antigen (the conserved C-repeat region (CRR) of the M6 protein of Streptococcus pyogenes).
3883 12009273 The secretion of functional cytokines by S. gordonii was achieved by in-frame fusion of sequences encoding mature IL-2 or IFN-gamma to the sequences encoding the leader signal of the M6 protein.
3884 12009285 In addition, RhIL-12 was found to produce a significant increase in gp120-specific proliferative responses and in the frequency of antigen-specific IFN-gamma and IL-2 producing T cells after restimulation of PBMC with gp120 in vitro indicating that RhIL-12 potentiates cell-mediated immune responses as well.
3885 12009571 Specifically, recombinant strains expressing IL-2 (known as GIDIL2) or TNF-alpha (GIDTNF) were compared with the parental, non-cytokine-secreting, strain (BRD509) for their ability to induce a variety of immune responses in susceptible BALB/c mice.
3886 12010968 PBMCs, cultivated with or without cytokines and exogenous CD40/CD40L signals, were stimulated with a crude parasite extract, recombinant vaccine candidates derived from conserved Ags (19-kDa C terminus of merozoite surface protein 1 [MSP1(19)], R23, and PfEB200), or recombinant Ags derived from the polymorphic Ags MSP1 block 2 and MSP2.
3887 12010968 Optimal Ab production required addition of interleukin-2 (IL-2) and IL-10 for all antigenic preparations.
3888 12012014 Induction of MUC1-specific cellular immunity by a recombinant BCG expressing human MUC1 and secreting IL2.
3889 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).
3890 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.
3891 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.
3892 12012014 Induction of MUC1-specific cellular immunity by a recombinant BCG expressing human MUC1 and secreting IL2.

3894 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.
3895 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.
3896 12023400 We enumerated with HLA-A*0201/peptide tetramers (tHLA) vaccine-elicited CD8(+) T cell precursor frequency among PBMC in 13 patients with melanoma undergoing vaccination with the HLA-A*0201-associated gp100:209-217(210 M) epitope.
3897 12023400 T cell precursor frequency increased from undetectable to 12,400 +/- 3,600 x 10(6) CD8(+) T cells after vaccination and appeared heterogeneous according to previously described functional subtypes: CD45RA(+)CD27(+) (14 +/- 2.6% of tHLA-staining T cells), naive; CD45RA(-)CD27(+) (14 +/- 3.2%), memory; CD45RA(+)CD27(-) (43 +/- 6%), effector; and CD45RA(-)CD27(-) (30 +/- 4.1%), memory/effector.
3898 12023400 The majority of tHLA(+)CD8(+) T cells displayed an effector, CD27(-) phenotype (73%).
3899 12023400 Epitope-specific in vitro stimulation (IVS) followed by 10-day expansion in IL-2 reversed this phenotype by increasing the number of perforin(+) (84 +/- 3.6%; by paired t test, p < 0.001) and CD27(+) (from 28 to 67%; by paired t test, p = 0.01) tHLA(+) T cells.
3900 12034104 The mice immunized with these peptides also induced higher T-helper activity, including Th1 type-cytokine (IL-2 and IFN-gamma) release.
3901 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.
3902 12057107 Interleukin-2 (IL-2) and interferon-alfa (IFN alfa)-based therapies remain the most commonly used agents to treat patients with advanced disease, demonstrating low but reproducible response proportions in the 10% to 20% range, with durable responses of 5% or less.
3903 12057119 Interferon (IFN)-alfa and interleukin (IL)-2 as single agents have produced response rates in the 15% to 20% range.
3904 12067407 Manipulation of immune responses to Mycobacterium bovis by vaccination with IL-2- and IL-18-secreting recombinant bacillus Calmette Guerin.
3905 12067407 We demonstrated that the secretion of biologically active IL-2 (rBCG/IL-2),but not IL-18 (rBCG/IL-18), by BCG improves its ability to induce and maintain a strong type 1 immune response in BALB/c mice. rBCG/IL-2 induced significantly higher Ag-specific proliferative responses, high IFN-gamma production and serum titres of IgG2a 16 weeks after vaccination.
3906 12067407 By comparison,vaccination with rBCG/IL-18 was found to induce significantly less IFN-gamma production in splenic lymphocytes than nBCG.

3909 12067407 By comparison,vaccination with rBCG/IL-18 was found to induce significantly less IFN-gamma production in splenic lymphocytes than nBCG.
3910 12068382 The presence of costimulatory molecules, such as B7-1 and B7-2, on antigen-presenting cells and the secretion of IL-2 promote the differentiation of recruited CD8+ lymphocytes into cytotoxic T lymphocytes.
3911 12069379 The cytokine used most extensively to date is interleukin-2 (IL2), a molecule that induces T lymphocyte proliferation and the generation of MHC unrestricted cytotoxicity.
3912 12078857 Interaction of disease-related antigen-reactive T-cell lines from multiple sclerosis patients with type IV collagen: role of integrin VLA-1 and effects of irradiation.
3913 12078857 Vaccination with T-cell lines reactive with myelin basic protein (MBP) and myelin oligodendrocytic glycoprotein (MOG) epitopes, expanded with interleukin-2 (IL-2), and attenuated by ionizing radiation is currently being evaluated as a therapeutic modality for this disease.
3914 12078857 Seven of 7 autoantigen-responsive T-cell lines from MS patients adhered to collagen IV, the major collagenous constituent of BMs.
3915 12078857 T-cell lines from healthy donors adhered more variably to collagen IV.
3916 12078857 Furthermore, patient derived T cells actively transmigrated through a collagen IV gel toward medium containing TNF-a, in a process that was inhibited by MAbs to VLA-1.
3917 12078857 Ionizing radiation at the dose used in vaccine preparation, inhibited morphological polarization associated with migratory capability, induced integrin clustering on the cell membrane, and abrogated adhesion to collagen IV.

3934 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.
3935 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.
3936 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.
3937 12082460 We have constructed and tested five recombinant adenoviruses (Ads) that express a variety of immunomodulators, including CD40 ligand (CD40L), a potent costimulator of several components of the immune system.
3938 12082460 Subsequently, using a therapeutic approach, we found that local, intratumoral coinjection of CD40L- and IL-2-expressing Ads was superior to any other agents tested and resulted in an at least 1.9-fold increase in mean survival time, in contrast to systemic application of recombinant CD40L or GM-CSF proteins, which had no significant effects.
3939 12082460 When using vaccination as a therapeutic approach, the combinations of CD40L plus IL-2 or GM-CSF plus IL-2 from Ad gave rise to an extended (2.8-fold) increase in mean survival time.
3940 12082460 A detailed analysis of immune cells present within regressing tumors indicated that mainly CD4(+) and CD8(+) T cells, and to a lesser extent dendritic cells, infiltrated the tumor mass, but not NK cells, macrophages, or granulocytes.
3941 12082460 These results propose that a combination of CD40L plus IL-2 has an improved efficacy over the use of single agents when applied for direct in situ therapy or vaccination therapy.

3952 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.
3953 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.
3954 12097595 The cellular immune responses generated by VLP immunization were both Th1 and Th2, since peripheral blood mononuclear cells from vaccinees, but not placebo recipients, secreted interleukin 2 (IL-2), IL-5, and gamma interferon (IFN-gamma) in response to in vitro stimulation with HPV-11 VLP.
3955 12097595 The proliferation-based SI was moderately correlated with IFN-gamma production and significantly correlated with IL-2 production after the third immunization (P = 0.078 and 0.002, respectively).
3956 12097595 The cellular immune responses generated by VLP immunization were both Th1 and Th2, since peripheral blood mononuclear cells from vaccinees, but not placebo recipients, secreted interleukin 2 (IL-2), IL-5, and gamma interferon (IFN-gamma) in response to in vitro stimulation with HPV-11 VLP.
3957 12097595 The proliferation-based SI was moderately correlated with IFN-gamma production and significantly correlated with IL-2 production after the third immunization (P = 0.078 and 0.002, respectively).
3958 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).
3959 12117934 A higher expression of the interleukin-2 receptor was found on B and T cells from immunized mice when they were compared with control mice.
3960 12117934 Moreover, significantly increased levels of gamma interferon (IFN-gamma) were produced by CD4+ T cells when lymphocytes from immunized mice, but not from control mice, were cultured in the presence of staphylococcal antigens.
3961 12117934 Moreover, a significant increase in the percentage of IFN-gamma-producing CD4+ and CD8+ T cells was observed after S. aureus Ima challenge in immunized mice compared to challenged control mice.
3962 12117934 CD4+ and CD8+ T cells appear to be the main lymphocyte subpopulations involved in this response.
3963 12133941 These analyses revealed 1) optimal peptides capable of eliciting specific responses by themselves at doses as low as 2 pg/ml, with each log increase in dose eliciting ever-increasing frequencies of responding cells over a 4- to 5-log range; 2) significant augmentation of response frequencies at all submaximal peptide doses by CD28- and CD49d-mediated costimulation; 3) differential dose response and costimulatory characteristics for IFN-gamma and IL-2 responses; and 4) no association of activation requirements with the CD27-defined CD4(+) T cell memory differentiation pathway.
3964 12142031 T9 glioma cells expressing membrane-macrophage colony stimulating factor produce CD4+ T cell-associated protective immunity against T9 intracranial gliomas and systemic immunity against different syngeneic gliomas.
3965 12142031 CD4+ and CD8+ T splenocytes from immunized rats, when restimulated in vitro with T9 cells, produced interleukin-2 and -4.
3966 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.
3967 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.
3968 12149420 Stimulation of CD4(+) T cells induced similar levels of IL-2-and IL-4-like activity and interferon-gamma.
3969 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.
3970 12153522 Interleukin-2 (IL-2) basally and IL-2 and interferon-gamma (IFN-gamma) in response to GAD, were detected more frequently and at higher levels in diabetic compared to non-diabetic twins.
3971 12153522 OAS activity was increased in diabetic compared to non-diabetic twins and showed a correlation with basal IL-2 and GAD-stimulated IFN-gamma and IL-10.
3972 12153522 Interleukin-2 (IL-2) basally and IL-2 and interferon-gamma (IFN-gamma) in response to GAD, were detected more frequently and at higher levels in diabetic compared to non-diabetic twins.
3973 12153522 OAS activity was increased in diabetic compared to non-diabetic twins and showed a correlation with basal IL-2 and GAD-stimulated IFN-gamma and IL-10.
3974 12163272 IL-6, IL-8 and IL-12 were consistently detected in challenged animals that had been vaccinated.
3975 12163272 Other cytokines--IL-1, IL-2, TNF, TGF and interferons--were not detected.
3976 12163272 Although the IL-6 and IL-8 did not relate to protection, IL-12 production was highest in the protected vaccinated pigs.
3977 12163272 Thus, the induction of monocytic cell activity, demonstrable by the production of IL-6, IL-8 and IL-12, appears to play a critical role in FMDV emergency vaccine induction of the innate immune defences which relate to early protection against FMD.
3978 12184913 To assess the activities of ChIL-2 in vivo, we injected birds with recombinant ChIL-2 (rChIL-2) protein. rChIL-2 treatment induced peripheral blood lymphocytes to express cell surface IL-2 receptors (IL-2R) within 48 h and resulted in an increase in the proportion of peripheral blood CD4+ and CD8+ T cells.
3979 12198661 Bacterial motif DNA as an adjuvant for the breakdown of immune self-tolerance to pyruvate dehydrogenase complex.
3980 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.
3981 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).
3982 12208110 Peripheral blood cells showed increased interferon-gamma production and expression of interleukin-2 receptor (CD25) after stimulation with Mycobacterium avium subsp. paratuberculosis antigens.
3983 12213402 Comparative study of immune responses induced after immunization with plasmids encoding the HIV-1 Nef protein under the control of the CMV-IE or the muscle-specific desmin promoter.
3984 12213402 The predominant IgG2a isotype of anti-Nef antibodies and the cytokine profile, mostly IL-2 and IFN-gamma, produced by Nef-stimulated spleen cells indicated a Th1 response in plasmid-immunized mice, in contrast to mice immunized with Nef-CFA, where a Th2 response was induced.
3985 12218168 In addition, proliferation and ex vivo IFN-gamma production of HCV-tetramer+ cells, but not influenza-virus-specific T cells, were defective in chronically infected patients and could not be restored by in vitro stimulation with peptide and IL-2.
3986 12218888 The aim of immune-based therapies in HIV infection is to enhance numbers and function of CD4 and CD8 T lymphocytes especially specific anti-HIV cellular immune responses in order to allow immune control of viral replication.
3987 12218888 Intermittent administration of subcutaneous IL-2 results in substantial increases in CD4 cell counts in most HIV-patients.

3994 12225814 The effect of immunization with herpes simplex virus glycoprotein D fused with interleukin-2 against murine herpetic keratitis.
3995 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.
3996 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).
3997 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.
3998 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.
3999 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).
4000 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.
4001 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.
4002 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).
4003 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.
4004 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).
4005 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.
4006 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.
4007 12236413 The obvious rising of IL-2 in TPI group and TPI+IL-12 group before and after challenge was seen.
4008 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.
4009 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.
4010 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).

4012 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.
4013 12236413 The obvious rising of IL-2 in TPI group and TPI+IL-12 group before and after challenge was seen.
4014 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.
4015 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.
4016 12243780 Assessment of in vitro granuloma supernatant of spleen cells from PIII-loaded macrophages vaccinated mice revealed significant amounts of Th1-cytokines IFN-gamma and IL-2 compared to control cells.
4017 12350054 We provide evidence that patients with advanced breast and ovarian cancer can be efficiently vaccinated with autologous DC pulsed with HER-2/neu- or MUC1-derived peptides.
4018 12350054 In addition, in one patient vaccinated with the MUC1-derived peptides, CEA- and MAGE-3 peptide-specific T-cell responses were detected after several vaccinations.
4019 12350054 In a second patient immunized with the HER-2/neu peptides, MUC1-specific T lymphocytes were induced after seven immunizations, suggesting that antigen spreading in vivo might occur after successful immunization with a single tumor antigen.
4020 12350054 In this ongoing trial one patient with metastatic RCC developed a partial remission of the metastatic sites was induced after the first four vaccinations with MUC1 peptides pulsed DC, that was ongoing after the next cycles containing IL-2.
4021 12355355 In addition, antigen-stimulated spleen cells from mice primed with MVA-gD2 and boosted with either MVA-gD2 or pgD2 produced higher levels of interleukin-2 and interferon-gamma than did those from pgD2-primed mice, indicating that a prime-boost immunization strategy that uses the MVA and plasmid DNA vector dramatically enhances and diversifies the humoral and cellular immune response to HSV-2 gD.
4022 12381578 Cellular responses induced in two Creole goats by vaccination with killed Cowdria ruminantium (Cowdria) were confirmed by IFN-gamma production and interleukin-2 receptor (IL-2R) expression.
4023 12381578 Both CD4+ and CD8+ but not WC1+ T cells showed a substantial increase in cell surface expression of IL-2R molecules in response to whole Cowdria lysate.
4024 12384537 The vaccines used were recombinant vaccinia virus containing the transgenes for CEA and three T-cell costimulatory molecules [B7-1, ICAM-1, and LFA-3, designated recombinant vaccinia (rV)-CEA/TRICOM], with each transgene under the control of individual poxvirus promoters, and a replication-defective avipox virus (fowlpox; rF) containing the same four transgenes (designated rF-CEA/TRICOM).
4025 12384537 The results demonstrate that (a) continued boosting with vaccine is required to maintain CEA-specific T-cell responses, and boosting with rF-CEA/TRICOM is superior to boosting with rF-CEA; (b) a diversified vaccination protocol consisting of primary vaccination with rV-CEA/TRICOM followed by boosting with rF-CEA/TRICOM is more efficacious than homogeneous vaccination with rF-CEA/TRICOM in the induction of both CEA-specific T-cell responses and antitumor activity; and (c) the use of cytokines, local granulocyte macrophage colony-stimulating factor (GM-CSF) and low-dose systemic interleukin 2, in combination with vaccine is essential in inducing antitumor activity, as compared with the use of cytokines alone, or the use of vaccines without cytokine.
4026 12384537 Both GM-CSF and interleukin 2 were shown to contribute to the induction of CEA-specific T-cell responses.
4027 12384537 The vaccines used were recombinant vaccinia virus containing the transgenes for CEA and three T-cell costimulatory molecules [B7-1, ICAM-1, and LFA-3, designated recombinant vaccinia (rV)-CEA/TRICOM], with each transgene under the control of individual poxvirus promoters, and a replication-defective avipox virus (fowlpox; rF) containing the same four transgenes (designated rF-CEA/TRICOM).
4028 12384537 The results demonstrate that (a) continued boosting with vaccine is required to maintain CEA-specific T-cell responses, and boosting with rF-CEA/TRICOM is superior to boosting with rF-CEA; (b) a diversified vaccination protocol consisting of primary vaccination with rV-CEA/TRICOM followed by boosting with rF-CEA/TRICOM is more efficacious than homogeneous vaccination with rF-CEA/TRICOM in the induction of both CEA-specific T-cell responses and antitumor activity; and (c) the use of cytokines, local granulocyte macrophage colony-stimulating factor (GM-CSF) and low-dose systemic interleukin 2, in combination with vaccine is essential in inducing antitumor activity, as compared with the use of cytokines alone, or the use of vaccines without cytokine.
4029 12384537 Both GM-CSF and interleukin 2 were shown to contribute to the induction of CEA-specific T-cell responses.
4030 12384805 In the group with only one invaded lymph node, the estimated relapse rate was significantly lower ( P(adjusted)=0.0285) and the overall survival was increased ( P(adjusted)=0.039) in the TIL+IL-2 arm compared with the IL-2 only arm.
4031 12391194 High-affinity HLA-A(*)02.01 peptides from parathyroid hormone-related protein generate in vitro and in vivo antitumor CTL response without autoimmune side effects.
4032 12391194 Parathyroid hormone-related protein (PTH-rP), a protein produced by prostate carcinoma and other epithelial cancers, is a key agent in the development of bone metastases.
4033 12391194 We investigated whether the protein follows the self-tolerance paradigm or can be used as a target Ag for anticancer immunotherapy by investigating the immunogenicity of two HLA-A(*)02.01-binding PTH-rP-derived peptides (PTR-2 and -4) with different affinity qualities.
4034 12391194 PTH-rP peptide-specific CTL lines were generated from the PBMC of two HLA-A(*)02.01(+) healthy individuals, stimulated in vitro with PTH-rP peptide-loaded autologous dendritic cells and IL-2.
4035 12391205 Systemic administration of IL-15 augments the antigen-specific primary CD8+ T cell response following vaccination with peptide-pulsed dendritic cells.
4036 12391205 A recently identified cytokine, IL-15, shares many properties with IL-2 and may provide a preferential means of augmenting T cell-directed vaccine responses.
4037 12391205 We did not observe either enhanced resistance to activation-induced cell death or preferential generation of memory T cells as a result of treatment with IL-15 compared with IL-2.
4038 12391205 These studies show for the first time that IL-15 is capable of augmenting the primary CD8(+) T cell response to vaccination and contribute to the basis for future experiments exploring the clinical role of IL-15.

4043 12391256 Vaccination significantly expanded both virus-specific CD4(+) and CD8(+) T cell responses, and IL-2 further increased the vaccine-induced response to an immunodominant Gag epitope.
4044 12391256 Following antiretroviral treatment interruption, the viral set point was significantly lower in vaccinated than in control macaques for at least 4 consecutive mo, and viral containment was inversely correlated with vaccine-induced, virus-specific CD4(+) and CD8(+) T cell responses.
4045 12393580 We achieved this by immunization with a tyrosine hydroxylase (mTH)-based DNA vaccine, enhanced with the posttranscriptional regulatory acting RNA element (WPRE), derived from woodchuck hepatitis virus in combination with an antibody-cytokine fusion protein (ch14.18-IL-2) that targets interleukin-2 (IL-2) to the tumor microenvironment.
4046 12393580 Thus, up-regulation of interferon-gamma (IFN-gamma) expression in CD8(+) T cells occurred only in those animals that received the mTH-WPRE vaccine plus the ch14.18-IL-2 boost.

4049 12399202 CD4+ and CD8+ mediated cellular immune response to recombinant influenza nucleoprotein.
4050 12399202 The stimulatory properties of soluble recombinant influenza nucleoprotein (NP) on purified CD4(+) and CD8(+) T cells from young and elderly individuals were studied.
4051 12399202 Recombinant influenza NP failed to induce proliferation of resting CD4(+) and CD8(+) T cells in the absence of IL-2.
4052 12399202 Addition of small amounts of IL-2, however, led to strong proliferation of resting CD4(+) and CD8(+) T cells from young and elderly donors.
4053 12399202 NP-reactive CD4(+) and CD8(+) T cell lines from both age groups grew equally well under long-term culture conditions.
4054 12399202 Stimulation of CD8(+) T cells is presumably due to cross-presentation, as EBV-transformed MHC class I-positive cell lines, which are incapable of antigen processing, stimulated live influenza virus-reactive CD8(+) T cell lines when loaded with NP-derived immunodominant peptides but not following loading with the whole NP molecule.

4061 12406657 To examine the role of different T lymphocyte subsets in the development of this protective immunity, CD4(+), CD8(+) and gamma delta T cell receptor (TCR)(+) cells from peripheral blood of goat kids vaccinated with live attenuated strains of M. a. paratuberculosis were studied.
4062 12406657 After in vitro stimulation with purified protein derivate, the expression of gamma-interferon (IFN-gamma) and the activation marker interleukin-2 receptor (IL-2R) was analysed by flow cytometry.
4063 12406657 Close to all of the IFN-gamma producing cells were of the CD4(+) subset, while only a small number were CD8(+) cells.
4064 12406657 Depletion of CD4(+) cells lead to a decrease in the percentage of total gamma delta TCR(+) cells and gamma delta TCR(+)IL2-R(+) cells.
4065 12406657 Removing the gamma delta TCR(+) cells increased the relative numbers of CD4(+), but not the CD4(+)IL-2R(+) cells.
4066 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.
4067 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.
4068 12406881 Injection-site biopsies revealed increased cellularity caused by infiltration of CD4+ and CD8+ lymphocytes, eosinophils, and Langerhans cells.
4069 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.
4070 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).
4071 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.

4084 12407510 Various interleukin-2 (IL-2) dosing schedules and combinations with interferon alpha (IFN-alpha) have been tested in patients with advanced melanoma during the past decade.
4085 12407510 The response rates reported with IL-2 as a single agent or in combination with IFN-alpha varies from 10% to 41%, with a small, but remarkable proportion of durable responses.
4086 12407510 Subsequently, biochemotherapy regimens combining IL-2, IFN-alpha, and chemotherapy have been evaluated in phase II trials, which have suggested improved response rates.

4093 12412750 The first peak seemed to be mitogenically induced, as it was demonstrated in T cell cultures from asymptomatic HBsAg carrier, HB-immune donors as well as HB-susceptible controls and exhibited similar kinetics to that of the mitogen phytohaemagglutinin (PHA) induced IL-2 secretion.
4094 12433688 This lack of proliferative ability of HIV-specific CD8(+) T cells is defined by surface expression of CD57 but not by absence of CD28 or CCR7.
4095 12433688 This inability to proliferate in response to antigen cannot be overcome by exogenous interleukin-2 (IL-2) or IL-15.
4096 12433688 Furthermore, CD57 expression on CD8(+) T cells, CD4(+) T cells, and NK cells is a general marker of proliferative inability, a history of more cell divisions, and short telomeres.
4097 12441072 Enhanced clearance of herpes simplex virus type 1 and reduced herpetic eye disease in STAT6 knockout mice is associated with increased IL-2.
4098 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.

4117 12450689 In addition, the induction of high levels of IFNgamma and interleukin-2 (IL-2) mRNA in PBMC, splenocytes, and intraepithelial lymphocytes from the immunized animals was detected until at least 110 weeks post-inoculation.
4118 12455400 A number of novel adjuvants have been reported in recent years including: i) bacterial toxins such as cholera toxin, CT, and the Escherichia coli heat-labile enterotoxin, LT; ii) less toxic derivatives of CT and LT; iii) endogenous human immunomodulators, such as IL-2, IL-12, GM-CSF; iv) hormones; v) lipopeptides; vi) saponins, such as QS-21; vii) synthetic oligonucleotides containing CpG motifs (CpG ODN); viii) lipid 'A derivatives, such as monophosphoryl lipid A, MPL, and ix) muramyl dipeptide (MDP) derivatives.
4119 12480696 One subset of human NK cells (CD56(bright)) constitutively expresses the high-affinity interleukin 2 (IL-2) receptor and produces immunoregulatory cytokines.
4120 12480696 Here, we demonstrate that CD56(bright) NK cells are present in human lymph nodes and that endogenous T cell-derived IL-2, acting through the NK high-affinity IL-2 receptor, costimulates CD56(bright) NK cells to secrete IFN-gamma.

4124 12492573 In an attempt to improve the antitumoral potential, we added granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 2 (IL-2) to the protocol.
4125 12492573 In animals inoculated with 10(5) myeloma cells, treatment with IL-2 given as a single agent prolonged the median survival time (MST, 67 d) when compared with the tumour control group (MST 48 d), whereas GM-CSF did not elicit any survival benefit (MST 49 d).

4139 12496199 Th1-type spleen cell cytokine secretion of interleukin-2 (IL-2) and gamma interferon (IFN-gamma) was analyzed in response to purified Ag85 components and synthetic overlapping peptides covering the three mature sequences.
4140 12496199 In contrast, spleen cells from both mouse strains produced elevated levels of IL-2 and IFN-gamma following vaccination with Ag85A, Ag85B, and Ag85C DNA in response to peptides of the three Ag85 proteins, and the epitope repertoire was broader than in infected mice.

4143 12496450 IL-4-producing CD8+ T cells with a CD62L++(bright) phenotype accumulate in a subgroup of older adults and are associated with the maintenance of intact humoral immunity in old age.
4144 12496450 We now demonstrate an IL-4-producing subpopulation of CD8+ T cells in a subgroup of healthy older adults.
4145 12496450 This T cell subset is substantial in size and has a characteristic phenotype expressing CD45RO, CD28, CD62L, and CD25.
4146 12496450 IL-4-producing CD8+ T cells produce large amounts of IL-2 but not IFN-gamma or perforin, and these cells do not have a regulatory suppressive effect on other T cells.
4147 12496450 In vivo IL-4-producing CD8+ T cells can be stably detected over a year.
4148 12496450 In this age group, IL-4-producing CD8+ T cells are more frequent in persons who are still capable of raising a humoral immune response following immunization than in others who fail to produce protective Abs after vaccination.
4149 12507600 However, cancer treatment by recombinant IL-2 or IFN-alpha still represents today the best therapeutic way for the treatment of renal carcinoma, melanoma and in some cases lymphoma.
4150 12514432 CD4+CD25+ suppressor lymphocytes in the circulation of patients immunized against melanoma antigens.
4151 12514432 Murine studies have suggested that a population of CD4+ T cells expressing the alpha chain of the interleukin (IL)-2 receptor (CD25+) are phenotypically anergic in response to T cell receptor stimulation and can suppress the function of CD4+ and CD8+ T cells.
4152 12514432 CD4+ CD25+, CD4+ CD25-, and a 1:1 ratio of these isolated T cells were stimulated with soluble anti-CD3 antibody in the presence of irradiated T cell-depleted PBMCs, and proliferation was assessed by measuring [3H]thymidine incorporation.
4153 12514432 In 13 patients, isolated CD4+CD25+ T cells proliferated 68% (+/- 5.8%) less than separately cultured CD4+ CD25- T cells.
4154 12514432 Moreover, CD4+ CD25+ T cells suppressed the proliferation of an equal number of cocultured CD4+ CD25+ T cells in 11 of 13 patients by an average of 60% (+/- 4.9%).
4155 12514432 The degree of suppression was proportional to the numbers of CD4+ CD25+ T cells.
4156 12514432 Addition of high-dose IL-2 reversed the hypoproliferative phenotype of the CD4+ CD25+ T cells and abrogated their suppressive function.
4157 12514432 These studies demonstrate that anergic and functionally suppressive CD4+ CD25+ T cells exist in patients with melanoma undergoing tumor antigen immunization and thus may play a role in modifying the magnitude of the T cell response to immunization.

4166 12519306 When autologous T cells were co-cultured with BCG-exposed DC they became highly activated, as determined by display of CD25, CD54 and CD71 on both CD4+ and CD8+ cells.
4167 12519306 Cytokine production from T cells cultured with BCG-exposed DC was enhanced with elevated secretion of interleukin-2 (IL-2), IL-10 and interferon-gamma (IFN-gamma) and was produced by both CD4+ and CD8+ lymphocytes as determined by intracellular staining.
4168 12519306 In particular, IFN-gamma secretion was increased from 50 pg/ml to 25 000 pg/ml and IL-10 secretion increased from 20 pg/ml to 300 pg/ml in BCG-exposed DC co-cultures.

4288 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.
4289 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.
4290 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.
4291 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.

4307 12615426 Previously protein vaccines consisting of the extracellular domain of HER2/neu (ECD(HER2)) were shown to elicit an immune response that does not provide protection against transplantable tumors expressing HER2/neu.
4308 12615426 Here, we showed that when mice were vaccinated with a mixture of human ECD(HER2) and anti-human HER2/neu IL-12, IL-2 or GM-CSF fusion proteins, significant retardation of the growth of a syngeneic carcinoma expressing rat HER2/neu, and long-term survivors were observed.
4309 12615426 Splenocytes from mice vaccinated with ECD(HER2) plus IgG3-(GM-CSF) incubated with ECD(HER2) demonstrated significant proliferation and IFN-gamma secretion.
4310 12615426 Taken together these results suggest that vaccines including ECD(HER2) and Ab-cytokine fusion proteins may be used to elicit both humoral and cell-mediated responses against HER2/neu.
4311 12621087 BALB/c mice were immunized by three intramuscular inoculations of HSV-1 glycoprotein D (gD) DNA vaccine alone or in combination with a plasmid expressing mature IL-18 peptide.
4312 12621087 Both the serum IgG2a/IgG1 ratio and T helper 1-type (Th1) cytokines [IL-2 and interferon (IFN)-gamma] were increased significantly by the co-injection of the IL-18 plasmid compared with the injection of gD DNA alone.
4313 12621087 However, the production of IL-10 was inhibited by IL-18 plasmid co-injection.

4331 12639245 The thymic output of patients receiving highly active antiretroviral therapy (HAART) was assessed by sjTREC (signal joint T cell receptor rearrangement excision circle) analysis to determine the thymic contribution to CD4(+) T cell reconstitution during initial therapy and during interleukin 2 (IL-2) and/or Remune supplementation of HAART.
4332 12639245 HAART supplementation with IL-2 was observed to lead to rapid increases in CD4(+) T cells that were accompanied by sjTREC decreases.
4333 12639245 The results indicate CD4(+) T cell maintenance during initial treatment of HIV-1 with HAART and early CD4(+) T cell reconstitution of patients receiving IL-2 with HAART is largely due to thymus-independent mechanisms, with the thymus making a limited contribution.

4341 12654789 Therefore, we characterized the T-cell responses to H. pylori in H. pylori-infected individuals without any subjective symptoms and in uninfected control subjects and investigated the role of regulatory CD4+ CD25(high) T cells during infection.
4342 12654789 Sorted memory cells from infected individuals responded less than cells from uninfected subjects, and the unresponsiveness could be abolished by depletion of CD4+ CD25(high) regulatory T cells or the addition of interleukin 2.
4343 12654789 Furthermore, CD4+ CD25(high) T cells suppressed H. pylori-induced responses in cocultures with CD25(low/-) cells.
4344 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.
4345 12654805 The biological activity of IL-12 produced by the recombinant L. lactis strain was confirmed in vitro by its ability to induce gamma interferon (IFN-gamma) production by mouse splenocytes.
4346 12654805 An antigen-specific cellular response (i.e., secretion of Th1 cytokines, IL-2, and IFN-gamma) elicited by a recombinant L. lactis strain displaying a cell wall-anchored human papillomavirus type 16 E7 antigen was dramatically increased by coadministration with an L. lactis strain secreting IL-12 protein.
4347 12663797 Production of interleukin 2 and the ability to lyse target cells in vitro were the first functions compromised, followed by the ability to make tumor necrosis factor alpha, while gamma interferon production was most resistant to functional exhaustion.
4348 12665415 Within the immune model of therapy, progress in the application of immune-related drugs including older cytokines (IL-2, IFN-alpha) and of newer cytokine-variant and other cytokines are discussed.
4349 12668155 Functional abolishment of any one of these cytokines (IL-2, IL-6, IL-12, IL-18, GMCSF, TNF-alpha, or IFN-alpha, except IL-10) by neutralizing antibodies leads to reduced IFN-gamma production (19-82% inhibition in mouse and 44-77% inhibition in human systems, respectively).

4358 12670905 Suboptimal activation of CD8(+) T cells by melanoma-derived altered peptide ligands: role of Melan-A/MART-1 optimized analogues.
4359 12670905 We recently demonstrated that Melan-A/MART-1-reactive CTLs can be anergized by peptide analogues with partial agonist/antagonist functions, which selectively impair interleukin (IL)-2 release.
4360 12670905 HLA-bound peptide fractions were eluted from HLA-A*0201/Melan-A/MART-1(+) melanoma cells and analyzed for reconstitution of the MART-1-specific T-cell epitope.
4361 12670905 Among the peptide fractions able to induce IFN-gamma release by MART-1-specific T cells, only fraction 43-44 activated IL-2 production by anti-MART-1 T cells, whereas the remaining two fractions acted as peptide antagonists by inhibiting IL-2 release in response to the native epitope.
4362 12670905 A comparable down-modulation of IL-2 release could also be induced by the MART-1-derived peptide 32-40, previously identified in one of the two anergizing fractions.

4413 12670905 We recently demonstrated that Melan-A/MART-1-reactive CTLs can be anergized by peptide analogues with partial agonist/antagonist functions, which selectively impair interleukin (IL)-2 release.
4414 12670905 HLA-bound peptide fractions were eluted from HLA-A*0201/Melan-A/MART-1(+) melanoma cells and analyzed for reconstitution of the MART-1-specific T-cell epitope.
4415 12670905 Among the peptide fractions able to induce IFN-gamma release by MART-1-specific T cells, only fraction 43-44 activated IL-2 production by anti-MART-1 T cells, whereas the remaining two fractions acted as peptide antagonists by inhibiting IL-2 release in response to the native epitope.
4416 12670905 A comparable down-modulation of IL-2 release could also be induced by the MART-1-derived peptide 32-40, previously identified in one of the two anergizing fractions.
4417 12670905 A substantial deficit in IL-2 release was additionally detected in tumor-specific CD8(+) T cells infiltrating melanoma lesions.
4418 12670905 To overcome IL-2 impairment by peptide antagonists, anti-MART-1 T cells were generated by in vitro sensitization with the two optimized analogues Melan-A/MART-1(27-35) 1L (with superagonist features) and Melan-A/MART-1(26-35) 2L (with improved HLA-A*0201 binding).
4419 12670905 T cells raised with the superagonist Melan-A/MART-1(27-35) 1L showed resistance to the inhibition of IL-2 release mediated by melanoma-derived peptide fractions, whereas Melan-A/MART-1(26-35) 2L-specific T cells appeared to be as sensitive as T cells raised with the parental epitope.
4420 12670905 This resistance was associated with the enhanced ability of Melan-A/MART-1(27-35) 1L-specific T cells to release IL-2.

4422 12678888 Various methods have been used to enhance the immune response to HB vaccination such as recombinant adjuvants, thymopentine, IL-2, levamisole and GM-CSF: they have produced variable results.
4423 12688838 The two most widely investigated immunotherapy drugs for melanoma are interferon (IFN)-alpha and interleukin-2 (IL-2).

4427 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.
4428 12706680 This effect was due to activation of MHC class I-restricted CD8(+) T cells coupled with an increased secretion of proinflammatory cytokines IFN-gamma, TNF-alpha and IL-2.
4429 12706680 Also, specific activation of dendritic cells was indicated by a two-three-fold upregulation of their costimulatory CD80 and MHC class II molecules.
4430 12706698 Group 1 received non-coding plasmid DNA only (control), group 2 received the E2 coding plasmid (0.5mg) plus non-coding plasmid DNA (0.5mg) and groups 3 and 4 received the E2 coding plasmid plus plasmid encoding either bovine interleukin 2 (IL-2) or granulocyte macrophage colony stimulating factor (GM-CSF) respectively.

4489 12733143 Interleukin-6 (IL-6) and IL-2 with their soluble receptors (IL-3, IL-4, IL-10, and IL-11) have been examined.
4490 12733143 In addition, control over production of IL-6 may be exerted by other ILs such as IL-1beta and IL-10.

4493 12733143 Serum levels of IL-6, sIL-6R, sIL-2R, and the expression of membrane-bound IL-2 receptors, both on bone marrow plasma cells and on peripheral blood mononuclear cells, are correlated with disease activity and disease stage.

4504 12738360 We first demonstrated that this method is adequate to measure the induction of interleukin (IL)-1beta and IL-1 receptor antagonist (IL-1 RA) mRNA upon the addition of bacterial lipopolysaccharide (LPS) to whole blood.
4505 12738360 Finally, we demonstrated that this methodology can be used successfully to assess inflammatory as well as T cell responses in vivo, as it allowed to detect the induction of IL-1beta and IL-1 RA after injection of LPS in healthy volunteers, and also the induction of IL-2 upon recall immunisation with tetanus vaccine.
4506 12743131 Intracavitary interferon alfa, interferon gamma, and interleukin-2 alone or in combination with cytotoxic therapy in phase I and II trials demonstrated intraperitoneal lymphoid cell stimulation and produced antitumor responses.
4507 12744869 Antigen entrapped in the escheriosomes leads to the generation of CD4(+) helper and CD8(+) cytotoxic T cell response.
4508 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.
4509 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.
4510 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.
4511 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).
4512 12775574 Induction of allopeptide-specific human CD4+CD25+ regulatory T cells ex vivo.
4513 12775574 Although CD4+CD25+ regulatory T cells are pivotal in the prevention of autoimmunity and appear to mediate transplantation tolerance, little is known concerning their antigen specificity.
4514 12775574 Here we describe the induction of a human CD4+CD25+ regulatory T-cell line specific for a defined peptide alloantigen (human leukocyte antigen A2 [HLA-A2] 138-170) by priming purified CD4+CD25+ cells ex vivo.
4515 12775574 The regulatory cells were anergic and retained their ability to suppress antigen-driven responses of CD4+CD25- cells.
4516 12775574 They inhibited not only interleukin 2 (IL-2) secretion by CD4+CD25- T cells specific for the same peptide but also direct alloresponse of naive CD4+CD25- T cells stimulated by semiallogeneic dendritic cells (DCs) in the presence of the peptide ("linked suppression").
4517 12775574 These findings suggest that peripheral CD4+CD25+ regulatory cells are a precommitted cell lineage from which cells with specificity for non-self-peptides can be selected.
4518 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.
4519 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).
4520 12782590 This vaccine also induced MHC class I antigen-restricted CD8(+) T-cell responses.
4521 12782590 The up-regulation of activation markers CD69 and CD25 on CD8(+) CTLs correlated with antigen-specific strong CTL responses in vitro.

4523 12794148 Both lymphotoxin-alpha and TNF are crucial for control of Toxoplasma gondii in the central nervous system.
4524 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.
4525 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.
4526 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.
4527 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.
4528 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.
4529 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.
4530 12794148 Generation and infection of bone marrow reconstitution chimeras demonstrated an exclusive role of hematogeneously produced TNF and LTalpha for survival of toxoplasmosis.
4531 12794148 These findings demonstrate the crucial role of both LTalpha and TNF for control of intracerebral toxoplasms.

4542 12805440 Stimulation of peripheral blood mononuclear cells from healthy donors and of tumor-associated lymphocytes from ovarian and breast cancer patients with DCs infected with KIF-NS virus (KIF-NS DC) induced CTLs that specifically recognized the peptide KIF and HER-2-expressing tumors in cytotoxicity assays and secreted gamma interferon (IFN-gamma) and interleukin-2 at recall with peptide.
4543 12808218 The short insert including RANTES and IL-5 resulted in the successful expression from SHIV-3sj, while the construct having longer genes including IL-2, IL-6 and IL-12p35 failed to become replication competent.
4544 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.
4545 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.
4546 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.
4547 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.
4548 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.
4549 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.
4550 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).
4551 12845773 Furthermore, a Major Histocompatibility Complex (MHC)-class-I-restricted T cell activation ELISPOT assay showed elevated interferon-gamma, interleukin-2, and interleukin-12 production in HA/SHIV 89.6 VLP-immunized mice, indicating that phenotypically mixed HA/SHIV 89.6 VLPs can enhance both humoral and cellular immune responses at multiple mucosal sites.
4552 12851699 Murine neuroblastoma C1300 cells transduced with the interleukin-2 (IL-2), IL-4 or granulocyte-macrophage colony-stimulating factor (GM-CSF) gene (C1300/IL-2, C1300/IL-4 or C1300/GM-CSF) were used as cytokine-producers.
4553 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.
4554 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.
4555 12851699 Murine neuroblastoma C1300 cells transduced with the interleukin-2 (IL-2), IL-4 or granulocyte-macrophage colony-stimulating factor (GM-CSF) gene (C1300/IL-2, C1300/IL-4 or C1300/GM-CSF) were used as cytokine-producers.

4557 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.
4558 12851699 Murine neuroblastoma C1300 cells transduced with the interleukin-2 (IL-2), IL-4 or granulocyte-macrophage colony-stimulating factor (GM-CSF) gene (C1300/IL-2, C1300/IL-4 or C1300/GM-CSF) were used as cytokine-producers.
4559 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.
4560 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.
4561 12853154 Stimulated T-lymphocytes produced IL-2, and in response to protease-derived peptides, also IFN-gamma.
4562 12857959 Growth of primary s.c. tumor and dissemination of pulmonary metastases was markedly suppressed by this oral DNA vaccine, carried by attenuated Salmonella typhimurium, encoding murine Fos-related antigen 1, fused with mutant polyubiquitin, and cotransformed with secretory murine IL-18.
4563 12857959 Markedly increased specific target cell lysis was mediated by both MHC class I-restricted CD8+ T cells and natural killer cells isolated from splenocytes of vaccinated mice, including a significant release of proinflammatory cytokines IFN-gamma and IL-2.
4564 12860162 IL-2 is itself a useful component of combination immunotherapy, such as with melanoma peptide vaccines, or with interferon-alfa-2b, (IFN-a), as a dual combination or part of a biochemotherapy regimen.
4565 12860163 Encouraging attempts have been made with plasmapheresis, indomethacin, low-dose cyclophosphamide, anti CTLA-4, anti FAS ligand and, perhaps in the future, more judiciously applied chemotherapy.
4566 12860163 Recombinant IL-1 and IL-2 by themselves, and in combination, were inactive.
4567 12861355 Furthermore, a synergistic effect achieved by combining targeted IL-2-immunotherapy with an antiangiogenic inhibitor of integrin alpha(v)beta(3) extends the potential of this immunotherapeutic strategy in combination with antiangiogenesis as demonstrated in three syngeneic tumor models.
4568 12871214 Interleukin-2, tumour necrosis factor-alpha and interferon-gamma production by T cells in proliferation assays with HBV-MoDC was significantly lower than with control-MoDC and correlated with lower IL-12 production in HBV-MoDC cultures.

4570 12900767 The MHC Class II+/Ii- tumor cell phenotype is created by transfecting genes for either CIITA or IFN-gamma, and inhibiting induced Ii mRNA by an Ii reverse gene construct (Ii-RGC).
4571 12900767 Here we show that at 5 MOI (multiplicity of infection), recombinant adenoviruses with CIITA or IFN-gamma genes converted virtually all MC-38 colon adenocarcinoma cells and Renca renal carcinoma cells in culture to MHC Class II+/Ii+ cells.
4572 12900767 A single recombinant adenovirus with both genes for IFN-gamma and Ii-RGC (rAV/IFN-gamma/Ii-RGC) efficiently induced the MHC Class II+/Ii- phenotype.
4573 12900767 Injection of tumor nodules with rAV/Ii-RGC and rAV/CIITA/IFN-gamma combined with a suboptimal dose of rAV/IL-2 induced a potent antitumor immune response.
4574 12909408 In order to investigate these effects on the canine immune system and to elucidate possible mechanisms we determined the following immune parameters in the blood of 33 clinically sound German shepherd dogs before and after standard vaccination with a polyvalent vaccine against distemper, parvovirus, viral hepatitis, leptospirosis, kennel cough and rabies: white and differential blood cell count, the serum concentrations and/or activities of IL-1, IL-2, IFN-gamma, TNF-alpha, neopterin and IgG, natural killer (NK) cell activity, bactericidal activity and complement hemolytic activity, lymphocyte proliferation test (LPT) and nitroblue tetrazolium test (NBT).
4575 12918057 MHC class I- and II-restricted peptide epitopes, antigenic proteins, viral constructs, mini-genes and whole tumor cells have been used either alone or combined with different cytokines (i.e., IL-2, IL-12, GM-CSF), adjuvants (incomplete Freund's adjuvant, montanide, QS21) or with dendritic cells to induce specific immune responses in vivo.
4576 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.
4577 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.
4578 12922132 The fraction RP18-1 contained DS saponin adducts of N-dicyclohexylurea, and stimulated Th2 immunity with production of IgG1, while the RP18-2 fraction contained the dodecylamide derivatives of DS saponins and stimulated Th1 immunity with production of IgG2a, IFN-gamma, IL-2, and CTL.
4579 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.
4580 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.
4581 12937634 Preclinical studies provided the regulatory, mechanistic and functional principles for cytokine gene-modified tumor vaccines and led to a number of phase I/II studies, including trials with IL-7-, IL-12-, GM-CSF- or interferon gamma-secreting tumor cell vaccines or IL-2 gene-transfected cell-based vaccines.
4582 12937899 To improve the antitumor effect of DC vaccine, Th1-biasing cytokine interleukin (IL) 18 and melanoma-associated antigen gp100 were cotransfected into bone marrow-derived DC (IL-18/gp100-DC), which were used as vaccine to induce the protective and therapeutic immunity in a B16 melanoma model.
4583 12937899 Immunization with IL-18/gp100-DC resulted in tumor resistance in 87.5% of the mice challenged with B16 cells; however, 12.5% and 25% of mice immunized with gp100 gene-modified DC (gp100-DC) or IL-18 gene-modified DC (IL-18-DC) were tumor free, respectively.
4584 12937899 Immune cell depletion experiments identified that CD4(+) T cells also played an important role in the priming phase of antitumor immunity and CD8(+) T lymphocytes were the primary effectors. gp100-specific CTL response were induced most markedly in the tumor-bearing mice immunized with IL-18/gp100-DC.
4585 12937899 Administration with such vaccine also significantly increased the production of Th1 cytokine (IL-2 and interferon-gamma) and induced infiltration of inflammatory cells inside and around the tumors.
4586 12937899 These results indicate that immunization with DC vaccine coexpressing Th1 cytokine IL-18 and tumor antigen gene may be an effective strategy for a successful therapeutic vaccination.
4587 12942200 IL-2 is itself a useful component of combination immunotherapy, such as with melanoma peptide vaccines, or with interferon alpha-2b, (IFN-alpha), as a dual combination or part of a biochemotherapy regimen.
4588 12942200 Combinations of 5-fluorouracil (5-FU) and IFN-alpha or levamisole have had efficacy in colon and head and neck cancers, but here the biological agents have been biochemical modulators, not immunotherapy.
4589 12943498 Biological therapies with IFN-alpha and IL-2 have demonstrated a real but minimal effect.
4590 12944986 We inserted the genes encoding the MHC class I-restricted antigenic epitope of chicken ovalbumin and tyrosinase-related protein 2 into the signal sequence of the interleukin-2 gene, replacing part of the signal sequence at different positions.
4591 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.
4592 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.
4593 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.
4594 12950684 Fusion of interleukin-2 to subunit antigens increase their antigenicity in vitro due to an interleukin-2 receptor beta-mediated antigen uptake mechanism.
4595 12950684 The use of anti-IL-2 receptor beta (IL-2Rbeta) antibody to block the receptor subunit on macrophages suggested that the adjuvancy exerted by IL-2 in our in vitro system is due to, at least in part, a previously unreported IL-2Rbeta-mediated antigen uptake mechanism.

4598 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.
4599 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.

4603 12957792 Kinetically, IFN-gamma and IL-10 levels decreased consistently from day 0 to days 14 and 60 in VMM patients.
4604 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.
4605 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.
4606 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.
4607 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.
4608 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.

4614 12960315 Infiltration with both CD4(+) and CD8(+) T lymphocytes was significantly more extensive in tumors from experimental mice than in tumors from control mice.
4615 12960315 CD63 was immunogenic in 2 of 13 melanoma patients, pointing to the potential of this Ag, combined with IL-2, as a vaccine for melanoma patients.
4616 12965919 Specifically the following parameters were assessed in baboons from 6 months to 26 years of age: relative numbers of B lymphocytes, CD4+ and CD8+ T lymphocytes, and T lymphocytes expressing CD28, CD25, and phytohemagglutinin-stimulated lymphoproliferative activity; and concentrations of total immunoglobulin, soluble interleukin-2 receptor alpha, and soluble CD30 in serum.
4617 12965919 The increase in T-cell numbers involved both the CD4+ and CD8+ subsets.

4628 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.
4629 14500509 T-cell responses, as measured by activation via interleukin-2 production, as well as antibody responses were comparable in the ICAM-1(-/-) and wild-type mice.

4651 14563689 Rapid induction of autoantibodies against Nogo-A and MOG in the absence of an encephalitogenic T cell response: implication for immunotherapeutic approaches in neurological diseases.
4652 14563689 As antigen targets, we used Nogo-A and the strongly encephalitogenic myelin-oligodendrocyte glycoprotein (MOG).
4653 14563689 In contrast to subcutaneous immunization with MOG, in vitro cytokine secretion assays (IL-2, IL-10, and IFN-gamma) did not reveal activation of MOG-specific T cells after intrasplenic immunization.
4654 14573640 This response was increased by the coadministration of a plasmid encoding the granulocyte-macrophage colony-stimulating factor (pGM-CSF).

4660 14579266 We show that E. coli LPS-pulsed MDDC released Th1-biasing cytokines - consisting of high levels of IL-12 p70, IFN-gamma-inducible protein 10 (IP-10) - but also TNF-alpha, IL-10, IL-6 and IL-1beta.
4661 14579266 In contrast, no IL-12 p70 or IP-10, and lower levels of TNF-alpha and IL-10 were induced by P. gingivalis LPS.
4662 14579266 These differences were sustained at LPS doses that yielded nearly equivalent maturation of MDDC; moreover the T cell response was consistent: E. coli LPS-pulsed MDDC induced higher T cell proliferation, and T cells released more IFN-gamma and IL-2, but less IL-5 than T cells co-cultured with P. gingivalis LPS pulsed-MDDC.
4663 14604574 Spleen cells from these mice strongly proliferated and presented significant increase of IL-2 and IFN-gamma concentrations in their supernatant upon antigen stimulation.

4755 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.
4756 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.
4757 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.
4758 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.

4891 14999599 In vitro human memory CD8 T cell expansion in response to cytomegalovirus requires CD4+ T cell help.
4892 14999599 Expansion of memory CD8(+) T cells was completely dependent on the presence and function of CD4(+) T cells, whose "help" also could be induced by exposure to irrelevant antigen.
4893 14999599 Recombinant interleukin (IL)-2 or IL-15 could substitute for help provided by CD4(+) T cells, whereas CD8(+) T cell expansion was blocked by anti-IL-2 but not anti-IL-15 antibody.
4894 14999599 Human memory CD8(+) T cells expand dramatically in vitro in response to cross-presentation of HCMV antigens, and, in contrast to observations made in murine systems, this proliferation was critically dependent on CD4(+) T cells that provide essential IL-2.
4895 14999599 Thus, in humans, cross-presentation and expansion of memory CD8(+) T cells may be compromised in disease states that result in deficits in CD4(+) T cell numbers or function, such as may be seen in human immunodeficiency virus type 1 infection.

4902 15004163 Nasal Flt3 ligand cDNA elicits CD11c+CD8+ dendritic cells for enhanced mucosal immunity.
4903 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.
4904 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.
4905 15004163 Moreover, these DCs expressed high levels of CD40, CD80, CD86, and MHC class II molecules.
4906 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).
4907 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.
4908 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.
4909 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.
4910 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.
4911 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.
4912 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).

4917 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.
4918 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.
4919 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.
4920 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).
4921 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.
4922 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.
4923 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.
4924 15064826 Susceptibility involves IL-10 but not IL-4, and B cells.
4925 15064826 In immune animals, upon re-infection, the elements involved in resistance are different, i.e., CD8+ T cells and IL-2.
4926 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.

4935 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.

4949 15096553 When mice were immunized intranasally with recombinant lactococci expressing either inducible or constitutive E7, an antigen-specific cellular response (i.e. secretion of IL2 and IFN-gamma cytokines) was evoked and was substantially higher in mice receiving L. lactis expressing E7 with the inducible system.
4950 15097300 Daily low-dose subcutaneous interleukin-2 added to single- or dual-nucleoside therapy in HIV infection does not protect against CD4+ T-cell decline or improve other indices of immune function: results of a randomized controlled clinical trial (ACTG 248).
4951 15100273 CY plus IL-2 treatment not only enhances proliferation and accumulation of effector CD4 cells, but also preserves the ability of these cells to express the effector cytokine IFN-gamma (and to a lesser extent TNF-alpha) in proportion to the level of parenchymal self-Ag expression.
4952 15100273 Although effector CD4 cells in CY plus IL-2-treated self-Ag-expressing mice eventually succumb to tolerization, this delay results in an increased level of in situ IFN-gamma expression in cognate Ag-expressing parenchymal tissues as well as death via a mechanism that requires direct parenchymal Ag presentation.

4955 15115073 The expression of SjC23 and p35, p40 in muscle tissue was determined by immunohistochemical method.
4956 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).
4957 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.
4958 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.
4959 15115073 The expression of SjC23 and p35, p40 in muscle tissue was determined by immunohistochemical method.
4960 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).

4963 15128763 However, the development of a protective systemic memory was substantially impaired by this measure, i.e., mice, which successfully rejected s.c. tumors of B16 melanoma after vaccination with dendritic cells pulsed with tyrosinase-related protein 2-derived peptides plus a boost with targeted IL-2, failed to reject a rechallenge with experimental pulmonary metastases.
4964 15128763 Detailed analysis revealed a change in the distribution of the tumor-reactive T cell population: although targeted IL-2 expanded the local effector population, tyrosinase-related protein 2-reactive T cells were almost completely depleted from lymphatic tissues.

4967 15128786 Both vectors induced IL-12 and TNF-alpha, but only Lm-LLO-E7 induced IL-2 production by DCs.
4968 15128786 Lm-LLO-E7 also induced significantly higher levels of MHC class II molecules, CD40, and B7 costimulatory molecules (CD86, B7-H1, and B7-DC) on DCs than Lm-E7.
4969 15128786 A similar shift is also observed for B7-H1 and B7-DC molecules.
4970 15128787 Stimulation by soluble CD70 promotes strong primary and secondary CD8+ cytotoxic T cell responses in vivo.
4971 15128787 In this study we demonstrate that CD27 stimulation by soluble CD70 considerably enhances the magnitude and quality of the CD8(+) T cell response.
4972 15128787 Stimulation with soluble CD70 in the presence of Ag significantly enhanced the proliferation of CD8(+) T cells and their ability to produce IL-2 and IFN-gamma in vitro.
4973 15128787 Administration of Ag and soluble CD70 resulted in a massive (>300-fold) expansion of Ag-specific CD8(+) T cells in vivo, which was due to the enhanced proliferation and survival of activated T cells.
4974 15128787 In mice that received Ag and soluble CD70, CD8(+) T cells developed into effectors with direct ex vivo cytotoxicity.
4975 15128787 Thus, in addition to increasing the frequency of primed Ag-specific T cells, CD27 signaling during the primary response instills a program of differentiation that allows CD8(+) T cells to overcome a state of unresponsiveness.
4976 15128787 Taken together these results demonstrate that soluble CD70 has potent in vivo adjuvant effects for CD8(+) T cell responses.
4977 15128839 The Dsg3-specific Tr1 cells secreted IL-10, TGF-beta, and IL-5 upon Ag stimulation, proliferated in response to IL-2 but not to Dsg3 or mitogenic stimuli, and inhibited the proliferative response of Dsg3- and tetanus toxoid-responsive Th clones in an Ag-specific (Dsg3) and cell number-dependent manner.
4978 15128839 Moreover, their inhibitory effect was blocked by Ab against IL-10, TGF-beta, and by paraformaldehyde fixation.
4979 15128839 These observations strongly suggest that 1) Dsg3-responsive Tr1 cells predominate in healthy individuals, 2) their growth requires the presence of IL-2, and 3) they exert their Dsg3-dependent inhibitory function by the secretion of IL-10 and TGF-beta.
4980 15128839 The Dsg3-specific Tr1 cells secreted IL-10, TGF-beta, and IL-5 upon Ag stimulation, proliferated in response to IL-2 but not to Dsg3 or mitogenic stimuli, and inhibited the proliferative response of Dsg3- and tetanus toxoid-responsive Th clones in an Ag-specific (Dsg3) and cell number-dependent manner.
4981 15128839 Moreover, their inhibitory effect was blocked by Ab against IL-10, TGF-beta, and by paraformaldehyde fixation.
4982 15128839 These observations strongly suggest that 1) Dsg3-responsive Tr1 cells predominate in healthy individuals, 2) their growth requires the presence of IL-2, and 3) they exert their Dsg3-dependent inhibitory function by the secretion of IL-10 and TGF-beta.
4983 15140052 These fusion cells expressed major histocompatibility complexes (MHC) class I and II, CD86, CD11c and CD8alpha.
4984 15140052 Splenocytes from mice vaccinated with fusion cells showed increased production of interferon-gamma (IFN-gamma) and cytotoxic T-lymphocyte (CTL) activity as compared with those vaccinated with DCs or tumour cells alone, and CTL levels were higher in fusion/IL-2-vaccinated mice than in fusion/LacZ-vaccinated mice.
4985 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.
4986 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.
4987 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.
4988 15153510 Using plasmid vaccination with DNA encoding the putative phosphate transport receptor PstS-3 from Mycobacterium tuberculosis and 36 overlapping 20-mer peptides spanning the entire PstS-3 sequence, we determined the immunodominant Th1-type CD4(+) T cell epitopes in C57BL/10 mice, as measured by spleen cell IL-2 and IFN-gamma production.
4989 15153510 Furthermore, a potent IFN-gamma-inducing, D(b)-restricted CD8(+) epitope was identified using MHC class I mutant B6.C-H-2(bm13) mice and intracellular IFN-gamma and whole blood CD8(+) T cell tetramer staining.
4990 15153510 The CD4(+) and CD8(+) T cell epitopes defined for PstS-3 were completely specific and not recognized in mice vaccinated with either PstS-1 or PstS-2 DNA.
4991 15153510 These results highlight the potential of DNA vaccination for the induction and characterization of CD4(+) and particularly CD8(+) T cell responses against mycobacterial Ags.
4992 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.
4993 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.
4994 15173014 Immunoprevention of HER-2/neu transgenic mammary carcinoma through an interleukin 12-engineered allogeneic cell vaccine.
4995 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.
4996 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.
4997 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.
4998 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.
4999 15178000 Cell-mediated immune responses to a killed Salmonella enteritidis vaccine: lymphocyte proliferation, T-cell changes and interleukin-6 (IL-6), IL-1, IL-2, and IFN-gamma production.
5000 15178000 Increased production of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) by antigen-stimulated splenocytes following vaccination were, in general, more often observed in 4-wk-old compared with 8-mo-old chickens, whereas serum levels of these cytokines were consistently higher in the vaccinated birds compared with controls regardless of age.
5001 15178000 In contrast, no differences were noted with CD4+, CD8+, or TCRalphabeta+ cells at any time points examined.
5002 15178000 Higher levels of NO production were observed following stimulation with SE flagella at 4, 7, 11, and 14 days after SE vaccination while serum levels of IFN-gamma, IL-1, IL-6, and IL-8 were elevated only at day 7 post-vaccination.

5007 15179984 Combined treatment with IFN-a, IL-2 and 5-FU has demonstrated a survival benefit in a single randomized controlled trial.
5008 15213152 Furthermore, a lack of CD25 expression on dividing cells suggested that EtxB-mediated T-cell clonal expansion may occur without a sustained requirement for interleukin 2.
5009 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.
5010 15220412 In addition, monkeys developed Gag-specific interleukin-2-secreting T cells, presumably belonging to the CD4(+) T-cell subset, and antibodies to both Gag and the adenoviral vaccine carriers.
5011 15233729 Encouraging studies involving cytokines such as granulocyte/macrophage colony-stimulating factor, interleukin-2 (IL-2), IL-12, IL-18, and many others are examined.
5012 15233729 Notable chemokines that may offer hope in such efforts include IL-8, RANTES, CCL19, CCL21, and a few others.
5013 15233729 In addition, as more is discovered regarding the requirements for memory development of T cells, boosters involving key cytokines such as IL-15 and IL-23 may prove beneficial to long-term maintenance of the memory pool.
5014 15238076 A Helicobacter pylori-specific in vitro coculture system was established and used to study the role of CD4+CD25+ regulatory T cells (Treg) in gastritis development in mice with H. pylori infection.
5015 15238076 Using the Treg-depleted CD4+ T cells from immunized mice as effector cells, we compared the suppressive efficacy of Treg isolated from naïve, infected or immunized mice and found that Treg from naïve mice, and slightly less efficiently from infected mice, suppressed the CD25- effector T-cell response and in most cases were distinctly more efficacious than Treg isolated from immunized mice.
5016 15238076 The suppressive efficacy of Treg isolated from the differently treated mice correlated closely with production of interleukin-5 (IL-5) by the Treg and suppression of interferon-gamma and IL-2 production by the CD25- effector T cells.
5017 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.
5018 15254744 OK432 and PSK were examined in vitro, and compared with lipopolysaccharide (LPS) and a cytokine cocktail (IL-1beta, TNF-alpha, IL-6 and PGE2).
5019 15254744 In the immunophenotypical analysis, the expression of CD80 and CD83 of DCs stimulated with OK-432 increased significantly compared with PSK and medium, and this up-regulation was the same as levels of DCs stimulated with cytokine cocktail.
5020 15254744 DCs stimulated with OK-432 showed significantly higher production of IL-12 and Th1-type cytokines (IL-2 and IFN-gamma) compared with DCs stimulated with LPS or cytokine cocktail.
5021 15254748 They can be repaired, at least partially and in vitro, by cytokines (IFNgamma, TNFalpha) or by DNA demethylation/histone hyperacetylation procedures.
5022 15254748 The innate and adaptive antitumour immunity may be under some conditions interconnected: primary activation of the MHC class I-unrestricted surveillance mechanisms may lead to the production of IFNgamma by the activated NK/gammadelta T cells; the in situ produced IFNgamma may then up-regulate the MHC class I molecule expression on the tumour cell surface and in this way it may stimulate the more efficient, MHC class I-restricted, adaptive immunity.
5023 15254748 Either therapeutic procedures aiming at up-regulation of MHC class I expression, or enhancement of MHC class I-unrestricted (CD4+, NK, NKT, gammadelta T) tumour defence effector mechanisms by dendritic cell-based therapeutic vaccines, by cytokines (IL-2, IL-12, IFNgamma, GM-CSF), or by the cytokine gene-based, genetically modified tumour vaccines should be considered.
5024 15280930 A phase I trial of pVAX/PSA, together with cytokine granulocyte/macrophage-colony stimulating factor (GM-CSF) (Molgramostim) and IL-2 (Aldesleukin) as vaccine adjuvants, was carried out in patients with hormone-refractory prostate cancer.

5092 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.
5093 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.
5094 15336780 Using tetramer staining and limiting dilution analyses as monitors of CTL responses, we found significant increases in the number of antigen-specific CTL in circulation after vaccination with the MART-1(27-35) peptide (AAGIGILTV)-pulsed autologous APC, the MAGE-1(161-169) peptide (EADPTGHSY)-pulsed APC, or with autologous tumor lysate-pulsed APC.
5095 15336780 The decline in the CTL response was associated by a concomitant expansion of CD4(+) CD25(+)T cells.
5096 15336780 Analysis of postvaccine peripheral blood lymphocytes (PBL) from patients showed an increased amount of interleukin (IL)-10 secretion on in vitro stimulation with IL-2 after successive vaccination.
5097 15336780 Triple color flow cytometric analyses revealed cytoplasmic IL-10 in the CD4(+)CD25(+) T-cell fraction and the number of CD4(+)CD25(+) IL-10(+) T cells were found to increase significantly in postvaccine PBL.
5098 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.
5099 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.
5100 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.
5101 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.
5102 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.
5103 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.
5104 15363646 At enrollment we performed whole blood cultures for type 1 (interferon [IFN]-gamma, interleukin [IL]-2) and type 2/immunosuppressive (IL-5, IL-10) responses to mycobacterial antigens (purified protein derivative [PPD] and culture filtrate proteins [CFP]).
5105 15363646 The incidence of tuberculosis was not associated with IFN-gamma responses, but was higher among participants with IL-2 responses (adjusted rate ratios [RR]: PPD 3.48; CFP 3.99; P < 0.001).
5106 15363646 For tuberculin skin test-positive participants, high incidence was also associated with an IL-10 response to PPD (adjusted RR 6.24, P = 0.03); for those with a BCG scar, high incidence was associated with positive IL-5 responses (adjusted RRs: PPD 3.64, P = 0.006; CFP 3.44, P = 0.04).
5107 15363646 The association with IL-2 production may reflect a response to tuberculous infection or to activating disease; the associations with IL-10 and IL-5 are in keeping with the expected role of immunosuppressive or type 2 cytokines.
5108 15363646 At enrollment we performed whole blood cultures for type 1 (interferon [IFN]-gamma, interleukin [IL]-2) and type 2/immunosuppressive (IL-5, IL-10) responses to mycobacterial antigens (purified protein derivative [PPD] and culture filtrate proteins [CFP]).

5116 15381726 Loss of HIV-1-specific CD8+ T cell proliferation after acute HIV-1 infection and restoration by vaccine-induced HIV-1-specific CD4+ T cells.
5117 15381726 Virus-specific CD8(+) T cells are associated with declining viremia in acute human immunodeficiency virus (HIV)1 infection, but do not correlate with control of viremia in chronic infection, suggesting a progressive functional defect not measured by interferon gamma assays presently used.
5118 15381726 This functional defect can be induced in vitro by depletion of CD4(+) T cells or addition of interleukin 2-neutralizing antibodies, and can be corrected in chronic infection in vitro by addition of autologous CD4(+) T cells isolated during acute infection and in vivo by vaccine-mediated induction of HIV-1-specific CD4(+) T helper cell responses.
5119 15385926 Real-time PCR confirmed higher expression of genes for IL-2 and IFN-gamma in T cells stimulated with Apo-DC.
5120 15385926 Concurrently, no IL-10 and low IL-4 responses indicated that the immune response was primarily of the Th1 type.
5121 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).
5122 15456623 Levels of IL-4, 5 and 10 (Th2 profile) decreased while those of IL-2, IFN-gamma, and TNF-alpha (Th1 profile) decreased.
5123 15464846 Plasmid DNA expressing interleukin-2 (pIL2) was encapsidated in VLP using the reassembly property of VLP from disassembled L1 capsomeres. pIL2 in reassembled VLP showed stability against DNase I, indicating encapsidation.
5124 15471952 When measured in real time, peptide antigen and the cytokines, interleukin 12 (IL-12) and IL-18, independently regulate the on/off kinetics of protective (interferon gamma, tumor necrosis factor alpha) and immunomodulatory (IL-2, CD40L) cytokine production by activated T cells and memory T cells.
5125 15471952 The remarkable differences in effector functions elicited by innate or adaptive signals (IL-12/ IL-18 or peptide, respectively) illustrate the complex and stringent regulation of cytokine expression by CD8(+) T cells.
5126 15473356 Enolase immunization stimulated a predominant T-helper-1 (Th1) cytokine pattern in splenic cells and induced production of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) by purified CD4+ T cells.
5127 15485577 Effects of recombinant adenovirus-mediated expression of IL-2 and IL-12 in human B lymphoma cells on co-cultured PBMC.
5128 15485577 Combination treatment of recombinant IL-2 and IL-12 has been reported to be synergistic for inducing anti-tumor responses in solid tumors but the potential of IL-2/IL-12 gene modified B cell lymphoma cells has not been explored yet.
5129 15485577 Adenoviral transduction efficiencies were determined by GFP expression analysis and IL-2 and IL-12 cytokine production was quantified by enzyme-linked immunosorbent (ELISA) assays.
5130 15485577 An EuTDA cytotoxicity assay was used to compare cytotoxic activities of IL-2 and/or IL-12 stimulated PBMC against unmodified lymphoma cells.
5131 15485577 Adenoviral-expressed IL-2 and IL-12 similarly led to dose-dependent increases in proliferation rates of PBMC obtained from healthy donors.
5132 15485577 IL-2 and/or IL-12 transduced lymphoma cells were co-cultured with PBMC, which were assayed for their cytolytic activity against unmodified lymphoma cells.
5133 15485577 We found that IL-2 stimulated PBMC elicited a significant anti-tumor effect but not the combined effect of IL-2/IL-12 or IL-12 alone.
5134 15485577 CONCLUSION: This study demonstrates that the generation of recombinant adenovirus modified lymphoma cell vaccines based on lymphoma cell lines expressing IL-2 and IL-12 cytokine genes is technically feasible, induces increases in proliferation rates and cytotoxic activity of co-cultured PBMC, and warrants further development for the treatment of lymphoma patients in the future.

5271 15543094 Chronic hypoxia with the release of proinflammatory mediators IL-1alpha, IL-1beta and IL-6, and overloading of the cardiovascular and respiratory systems due to the narrowing airways and small pulmonary arteries of these children could also contribute to the development of these abnormalities.
5272 15543094 Moreover, chronic hypoxia of SIDS infants induced also production of hypoxia-inducible factor 1alpha (HIF-1alpha), which stimulated synthesis and release of different growth factors by vascular endothelial cells and intensified subclinical inflammatory reactions in the central nervous system, perhaps potentiated also by PACAP and VIP gene mutations.

5321 15585831 These results suggest that two distinct pathways mediate CD28-induced up-regulation of IL-2 expression, a PI3K-dependent pathway that may function through the immunological synapse to enhance IL-2 transcription and a PI3K-independent pathway that induces IL-2 mRNA stability.

5439 15653438 Using one CpG-ODN, DSP30, we observed that it could upregulate not only Toll-like receptor 9 (TLR9) mRNA expression in activated B-cells, but also the early expression of CD69 followed by the sequential expression of CD80, CD86 and the nuclear factor (NF)-kappaB pathway.
5440 15653438 Furthermore, mRNA expression of certain B-cell-derived cytokines was influenced by exposure to DSP30, with a strong upregulation of interleukin 6 (IL-6) and downregulation of IL1-beta.

5480 15699118 Contrasting effects of low-dose IL-2 on vaccine-boosted simian immunodeficiency virus (SIV)-specific CD4+ and CD8+ T cells in macaques chronically infected with SIVmac251.
5481 15699118 In this study, we investigated how continuous low-dose IL-2 affected the CD4+ and CD8+ T cell response induced by two inoculations of a canarypox recombinant SIV-based vaccine candidate in healthy macaques chronically infected with SIVmac251.
5482 15699118 Vaccination in the presence of IL-2 significantly augmented Gag-specific CD8+ T cell responses, but actually reduced Gag-specific CD4+ T cell responses.
5483 15699118 Although IL-2 at low doses did not change the overall concentration of circulating CD4+ or CD8+ T cells, it expanded the frequency of CD4+CD25+ T cells.
5484 15699118 Depletion of the CD4+CD25+ T cells in vitro, however, did not result in a reconstitution of Gag-specific CD4+ responses or augmentation of SIV-specific CD8+ T cell responses.
5485 15699118 Thus, we conclude that the decrease in virus-specific CD4+ T cell response may be due to IL-2-promoted redistribution of cells from the circulation, or due to Ag-induced cell death, rather than suppression by a T regulatory population.

5514 15714585 Many more Fas ligand-expressing and apoptotic cells were present after peptide immunization than after whole-protein immunization.
5515 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.
5516 15721842 Immunization of normal F344 rats with the NEU peptide modified with the N-terminal domain of CLIP (N-NEU) resulted in an immune response primarily consisting of type 1 (IL-2, IFNgamma) cytokine producing T cells.
5517 15721842 The functionally divergent responses elicited by the modified self-peptides were accompanied by significant changes in the expression of the CD28/CTLA4/B7 family of co-stimulatory molecules.
5518 15721842 Immunization with the N-NEU peptide led to enhanced expression of CD28 in the antigen-specific, CD4+ T cell compartment while expression of B7.1 was dramatically reduced in antigen-specific CD8+ T cells.
5519 15721842 Comparatively, expression of CTLA4 was down-regulated in the antigen-specific CD4+ T cell compartment following immunization with NEU-C peptide.
5520 15728501 In this study we show that in HIV-infected individuals the loss of IL-7R (CD127) expression defines the expansion of a subset of CD8(+) T cells, specific for HIV as well as other Ags, that show phenotypic (i.e., loss of CCR7 and CD62 ligand expression with enrichment in activated and/or proliferating cells) as well as functional (i.e., production of IFN-gamma, but not IL-2, decreased ex vivo proliferative potential and increased susceptibility to apoptosis) features of effector T cells.
5521 15728501 Importantly, in HIV-infected individuals the levels of CD8(+)CD127(-) T cells are directly correlated with the main markers of disease progression (i.e., plasma viremia and CD4(+) T cell depletion) as well as with the indices of overall T cell activation.
5522 15728501 In all, these results identify the expansion of CD8(+)CD127(-) effector-like T cells as a novel feature of the HIV-associated immune perturbation.
5523 15731219 Most animals recognized two CD8 and one CD4 epitope and had frequencies of IFN-gamma-responding T cells from 0.01 to 0.3% of total CD8 or CD4 T cells.
5524 15731219 T-cell responses were remarkably stable over time and, unlike responses in most immunodeficiency virus infections, maintained good functional characteristics, as evidenced by coproduction of IFN-gamma and interleukin-2.
5525 15731224 We showed recently that a recombinant HSV-1 vaccine expressing interleukin-4 (IL-4) is more efficacious against ocular HSV-1 challenge than recombinant viruses expressing IL-2 or gamma interferon (IFN-gamma) (Y.
5526 15735048 CD4(+) Treg cells do not secrete interleukin (IL)-10 and transforming growth factor beta cytokines but express CD25, the glucocorticoid-induced tumor necrosis factor receptor-related protein (GITR), and Forkhead Box P3 (Foxp3), and are capable of suppressing the proliferative responses of naive CD4(+) and CD8(+) T cells to stimulation with mitogenic anti-CD3 antibody.
5527 15735048 Importantly, these Treg cells suppress IL-2 secretion by CD4(+) effector T cells specific for either EBNA1 or a melanoma antigen, suggesting that these CD4(+) Treg cells induce immune suppression.

5546 15746068 The purpose of these studies was to develop immunogenic peptides derived from the CD19 and CD20 self-antigens for the induction of antigen-specific CTLs against B-cell malignancies.
5547 15746068 The CD19 or CD20 peptide-specific CTL cytotoxicity was confirmed using HLA-A2.1(+) T2 cells presenting the appropriate peptide.
5548 15746068 In addition, the CTLs displayed a significant (P < 0.05) increase in cell proliferation and IFN-gamma secretion (>830 ng/mL) following restimulation with HLA-A2.1(+)/CD19(+)/CD20(+) tumor cells.
5549 15746068 The CTLs also displayed a distinct phenotype consisting of a high percentage of CD69(+)/CD45RO(+) and a low percentage of CD45RA(+)/CCR7(+) CD4(+) or CD8(+) T cells characteristic of effector memory cell population.
5550 15746068 Cyclic guanosine 3',5'-monophosphate culture conditions using serum-free AIM-V medium containing human AB serum, recombinant human interleukin 2 (Proleukin) and CD3/CD28 Dynabeads were developed resulting in a 35-fold expansion of CD20 peptide-specific CTLs.
5551 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.
5552 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).

5556 15788145 There are many experimental trials using combined therapy for malignant melanoma, including chemotherapy (dimethyl triazene imidazole carboxamide) and biologic therapy (interleukin (IL)-2, interferon (IFN)-gamma, IFN-alfa).
5557 15797470 We generated a mammalian expression system for recombinant cytokines using the equine IgG1 heavy chain constant region as a tag for detection and purification of the expressed cytokine, demonstrated here using equine interferon-gamma (IFN-gamma), interleukin-2 (IL-2), interleukin-4 (IL4) and transforming growth factor-beta1 (TGF-beta1).
5558 15797470 The purification of the fusion protein by protein G affinity columns, the enterokinase digestion of the cytokine from the IgG1 heavy chain region after or during purification, and the biological activity of the cytokine within the fusion protein or after its isolation was demonstrated in detail for equine IFN-gamma/IgG1 by up-regulation of major histocompatibility complex (MHC) class II expression on horse lymphocytes.
5559 15797470 Biological activity could also be confirmed for the IL-2 and IL-4/IgG1 fusion proteins.

5565 15803143 To augment their nonspecific immunogenic properties, before DNA transfer, the fibroblasts (of C3H/He mouse origin) were modified to express allogeneic MHC class I H-2Kb-determinants and to secrete IL-2, IL-18 or GM-CSF.
5566 15803143 The immunotherapeutic properties of transfected fibroblasts modified to secrete IL-18 or GM-CSF were less efficacious.
5567 15804600 Immunized mice produced higher levels of both protein and gene transcripts for IFN-gamma, interleukin (IL)-2, IL-18 and MIP1-alpha.

5569 15812230 Nonreplicating recombinant vaccinia virus expressing CD40 ligand enhances APC capacity to stimulate specific CD4+ and CD8+ T cell responses.
5570 15812230 Recently, we and others have demonstrated, in vitro and in vivo, that coexpression of CD80 and CD86 costimulatory molecules enhances the immunogenic capacity of a recombinant vaccinia virus (rVV) encoding different tumor-associated antigens.
5571 15812230 To further investigate the capacity of these vectors to provide ligands for different costimulatory pathways relevant in the generation of T cell responses, we constructed a recombinant virus (rVV) expressing CD40 ligand or CD154 (CD154rVV).
5572 15812230 Upon binding the CD40 receptor expressed on antigen presenting cells (APC), this molecule, physiologically expressed on activated CD4+ T cells, increases their antigen presentation and immunostimulatory capacities.
5573 15812230 CD154rVV infection of autologous fibroblasts, monocytes, or iDC promoted the expression of a number of cytokines, including GM-CSF, TNF-alpha, and IL-15 in iDC.
5574 15812230 Most importantly, IL-12 p40 gene expression and protein secretion were induced by CD154rVV but not by wild-type VV (WT VV) in either CD14+ cells or iDC, and these effects could be blocked by anti-CD40 monoclonal antibodies.
5575 15812230 Furthermore, phenotypic characterization of CD154rVV infected iDC revealed enhanced expression of CD83 and CD86 surface markers as compared with wild-type vaccinia virus infection.
5576 15812230 However, cytokine genes typically expressed by T cell receptor triggered T cells such as those encoding IL-2 and IFN-gamma, or T cell proliferation, were detectable to a significantly higher extent in CD154rVV infected cultures, as compared with WT VV.
5577 15812230 Activation of specific CD8+ T cells was then investigated using MART-1/Melan-A(27-35) epitope as the model of tumor-associated antigen (TAA).
5578 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.
5579 15814697 DcR3/TR6, a secreted protein belonging to the TNF receptor superfamily, interacts with lymphotoxin-like, exhibits inducible expression, and competes with herpes simplex virus glycoprotein D for herpes virus entrance mediator (LIGHT), Fas ligand (FasL), and TL1A, all members of the TNF superfamily.
5580 15814697 Solid-phase TR6 can trigger reverse signaling of LIGHT and FasL expressed on T cells, and lead to T cell costimulation.
5581 15814697 We demonstrated that mastocytoma P815 cells expressing surface TR6 (TR6-P815) effectively augmented the T cells response in vitro and ex vivo in terms of proliferation, as well as IL-2 and IFN-gamma secretion.

5672 15941685 An increased capacity of CD3+ cells to produce interferon (IFN)-gamma and tumor necrosis factor (TNF)-alpha, and of the TCRgammadelta+ subset to produce TNF-alpha was seen in adults after stimulation of peripheral blood mononuclear cells (PBMC) with a late-stage, schizont-rich, parasite preparation.
5673 15941685 Mitogenic stimulation with PMA and ionomycin induced much higher frequencies of IFN-gamma- and TNF-alpha-expressing CD4+, CD8+ as well as TCRgammadelta+ cells in adults, while differences for interleukin (IL)-2 expression were restricted to CD4+ and CD8+ T cells.
5674 15941685 Impressive increases in the capacity to produce P. falciparum-specific and non-specific IFN-gamma and TNF-alpha appear to be the main cellular correlates of naturally acquired immunity in Central Africa.
5675 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.
5676 15947427 In presence of anti-CD3, the 57 kDa antigen was found to increase the level of IL-2 significantly instead of IL-4.
5677 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.

5697 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.
5698 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.
5699 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.
5700 16005745 In addition, spleen cells of vaccinated mice produced augmented levels of IL-2 and IFN-gamma when incubated with the crude parasite antigens, indicating that cellular immunity plays an important role in the protection.
5701 16019851 After local microwave coagulation and subsequent intra-tumoural injection of microparticles encapsulating interleukin-2 and granulocyte-macrophage colony-stimulating factor, the anti-tumour efficacy against subcutaneous Lewis lung carcinoma in syngeneic mice was evaluated.
5702 16034459 To explore the issue of immune-stimulation versus immune-suppression in immature lymphoblastic leukemia cells, two types of HSV-1 amplicon vectors, helper virus-dependent and helper virus-free that express the immunomodulatory molecules CD70 and IL-2, were compared with regard to their vector-associated immunomodulatory potential.
5703 16034459 Treatment of mice with vaccine cells transgenically expressing CD70+IL2 significantly suppressed lymphoblastic cell proliferation and improved survival.
5704 16034459 Of note, when helper virus-dependent HSV-1 amplicon vectors were used for vaccine preparation, the high immunogenic potential of the vector itself, in the absence of transgenic CD70+IL2 expression, seemed to be sufficient to mediate protection comparable to the antineoplastic response achieved by expression of immunomodulatory molecules.

5711 16041023 Recombinant Ags 85A, 85B, and 85C induced significant lymphocyte proliferation as well as the production of gamma interferon (IFN-gamma), interleukin-2 (IL-2), IL-12, and tumor necrosis factor alpha (TNF-alpha), but not IL-4, from low and medium shedders.
5712 16041023 The 35-kDa protein also induced significant lymphocyte proliferation as well as the production of IFN-gamma and IL-4 from low and medium shedders.
5713 16041023 CD4(+) T cells and CD25(+) (IL-2R) T cells were stimulated the most by 85A and 85B, while the 35-kDa protein primarily stimulated CD21(+) B cells involved in humoral immune responses.
5714 16044253 Splenocytes obtained from 3H1-CpG-immunized mice showed an increased proliferative CD4(+) Th1-type T-cell response when stimulated in vitro with 3H1 or CEA and secreted elevated levels of Th1 cytokines (IL-2, IFN-gamma).
5715 16044253 This vaccine also induced MHC class I antigen-restricted CD8(+) T-cell responses.
5716 16047142 The anti-PSA immune responses were skewed toward Th1, as shown by high IFNgamma and IL-2 production.
5717 16051859 Moreover, the IL-2-expressing virus showed an enhanced CD8+ response to viral antigens in mice after a single intranasal immunization.
5718 16061685 Further, the IFN-gamma enzyme-linked ImmunoSPOT and in vitro 51Cr release assay results showed that HLA-A2-restricted, CEA-specific CTL responses were induced in both mucosal and systemic lymphoid tissues in A2 transgenic mice after oral immunization with PV-CEA.
5719 16061685 Finally, we showed that coadministration of papillomavirus pseudoviruses encoding interleukin-2 with PV-CEA enhanced the generation of A2-restricted, CEA-specific CTLs in aged CEA/A2 double transgenic mice, which were more clinically relevant.
5720 16078439 The obtained results will direct our further investigations toward obtaining mAbs for receptors for TNFalpha and IFNgamma, transfection of suppressor gene into tumor cell cultures and genes for IL-2 and TNFalpha.
5721 16078831 Our results also indicate that MDP-C is an effective stimulator for production of interleukin-2 and interleukin-12 by murine bone marrow derived dendritic cells (BMDCs) and production of interferon-gamma by CTLs.
5722 16078831 Additionally, MDP-C increases the expression levels of several surface molecules, including CD11c, MHC class I, and intercellular adhesion molecule-1 in BMDCs.

5788 16143434 Concomitant elevations in maternal serum cytokine levels were observed including interleukin (IL)-2, IL-10 and IL-12.
5789 16148095 Selectively impaired CD8+ but not CD4+ T cell cycle arrest during priming as a consequence of dendritic cell interaction with plasmodium-infected red cells.
5790 16148095 Moreover, within the naive T cell population, pRBC-treated DC were selectively deficient in priming CD8(+) but not CD4(+) T cells.
5791 16148095 The mechanisms underlying the inability of parasite-treated DC to prime CD8(+) T cells were explored. pRBC treatment of DC from wild-type C57BL/6, but not from IL-10 knockout animals, suppressed DC-mediated T cell priming across a Transwell, suggesting active IL-10-dependent suppression.
5792 16148095 The proliferation arrest was partially reversible by the addition of IL-2 or IL-7 to responder cultures.
5793 16148095 These results suggest that in malaria-endemic areas, priming of CD8(+) T cell responses may be more difficult to induce via vaccination than the priming of CD4(+) T cells.
5794 16149990 Abomasal lymph nodes and/or abomasal mucosa were collected and messenger RNA for the Th1 cytokines (IFN-gamma, IL-2, IL-12 p40 subunit), the Th2 cytokines (IL-4, IL-5, IL-6, IL-10, IL-13, IL-15) and the Th3/Tr cytokine TGF-beta was quantified by real-time RT-PCR.
5795 16149990 However, following infection all calves showed a significant decrease in the Th1 cytokines, IFN-gamma and IL-12 p40, and a significant increase in the Th2 cytokines, IL-4, IL-5, IL-10 and IL-13 in the lymph nodes, compared to non-infected calves.
5796 16149990 In contrast, a Th2 pattern was not observed in the mucosa of the infected calves, which exhibited an increase in IFN-gamma as well as in the Th2 cytokines IL-4, IL-5 and IL-10 mRNA.
5797 16151809 Antibody, CD8(+) T cell, and tumor-protective immune responses were markedly enhanced in mice immunized to OVA + IL-2 in liposomes compared to mice immunized to OVA, either alone or encapsulated into liposomes without IL-2.
5798 16157995 Laboratory tests showed a high level of serum myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) and soluble interleukin-2 receptor (sIL-2R), as well as abnormal renal function and urinary sediment.
5799 16162362 This study investigated the effect of swine interleukin 2 (IL-2) and swine interleukin 4 (IL-4) on the development of immune responses induced by a PRRSV-ORF7 DNA vaccine (phCMV-ORF7).
5800 16162362 Groups of 3-week-old certified PRRSV-free, castrated male, Yorkshire crossbred pigs, were vaccinated with or without the IL-2 or IL-4.
5801 16162362 The group of swine receiving the vaccine plus IL-2 had significant virus-specific blastogenic responses 3 weeks after the vaccine-cytokine boost, when compared to those of the experimental pigs that received the vaccine plus IL-4, vaccine alone, unvaccinated controls or the pigs vaccinated with the DNA vaccine cloned in the reverse orientation (phCMV-ORF7(Rev)).
5802 16162362 These results demonstrate that IL-2 has a positive inductive effect on the activation of vaccine-induced virus-specific cellular immunity, while IL-4 appeared to have a suppressive effect.

5815 16164822 On days 0, 30 and 90 a quantitative analysis was performed on lymphoproliferative responses to polyclonal mitogens, IL-2 and the specific antigen U, the production of specific serum and saliva IgA, IgM and IgG antibodies to all components of U and the concentration of pro-inflammatory cytokines.
5816 16164822 The highest concentrations of serum proinflammatory cytokines TNF-alpha, IL-1beta and IL-6 were registered at baseline followed by a decrease until the end of the observation period.
5817 16165219 Five groups received MLV vaccine with either bacterial endotoxin-derived adjuvant (ET), mixed open reading frame 5 (ORF5) peptides derived from various PRRSV isolates, porcine interferon alpha (IFNalpha), polyinosinic-polycytidylic acid stabilized with polylysine and carboxymethylcellulose (poly-ICLC), or porcine interleukin-12 (IL-12).
5818 16165219 Four-color flow cytometry was utilized to simultaneously identify three major porcine T-cell surface markers (CD4, CD8, and gammadelta TCR) and detect activation marker CD25 (alpha chain of IL-2 receptor) or intracellular IFNgamma.
5819 16165219 The MLV PRRSV vaccine alone successfully primed CD4(-)CD8(+)gammadelta- T-cells as demonstrated by a significant increase in %IFNgamma+ cells when live PRRSV was used as a recall antigen.
5820 16165219 Booster immunizations of mixed ORF5 peptides and co-administration of IL-12 with MLV PRRSV vaccine significantly enhanced IFNgamma expression by some T-cell subsets (CD4(-)CD8(+)gammadelta+ and CD4(-)CD8(-)gammadelta+ for mixed ORF5 peptides and CD4(+)CD8(+)gammadelta- and CD4(-)CD8(+)gammadelta+ for IL-12).
5821 16165219 Expression of IFNgamma by several T-cell subsets correlated with reduced lung lesions and viremia, whereas expression of CD25 did not.
5822 16165219 Expression of surface CD25 did not correlate with IFNgamma production.
5823 16168527 The immune responses, involved with escheriosome-sAg protection, were found to be associated with enhanced antigen specific CD4(+) and CD8(+) T-cell populations.
5824 16168527 Analysis of cytokine profiles in immunized animals revealed that the protective response was associated with the induction of a Th-1 (IL-2 and IFN-gamma) cells.
5825 16168555 Reverse transcription-polymerase chain reaction (RT-PCR) analysis demonstrated that PhIP attenuated IL-2 mRNA expression in the thymocytes and EL4 cells stimulated with phytohemagglutinin (PHA) plus phorbol 12-myristate 13-acetate (PMA).
5826 16168555 Furthermore, an electrophoretic mobility shift assay showed that PhIP inhibited DNA binding activity of nuclear factor for immunoglobulin kappa chain in B cells (NF-kappaB), activator protein-1 (AP-1) and nuclear factor of activated T cells (NF-AT), which are known to be responsible for IL-2 transcriptional activation.
5827 16168555 These results suggest that PhIP has potential immunosuppressive effects by inhibiting T-cell proliferation and IL-2 expression through down regulation of ROS generation and thereby inhibiting NF-kappaB, AP-1 and NF-AT activation.
5828 16168555 Reverse transcription-polymerase chain reaction (RT-PCR) analysis demonstrated that PhIP attenuated IL-2 mRNA expression in the thymocytes and EL4 cells stimulated with phytohemagglutinin (PHA) plus phorbol 12-myristate 13-acetate (PMA).

5834 16181494 Mycobacterial immune reconstitution inflammatory syndrome in HIV-1 infection after antiretroviral therapy is associated with deregulated specific T-cell responses: beneficial effect of IL-2 and GM-CSF immunotherapy.
5835 16181751 Full-length feline B7.1 and B7.2 produced from SPV vectors were natively processed and costimulated Jurkat cells to produce IL-2, in vitro.
5836 16181751 Although feline sB7.1-his and sB7.2-his proteins bound to the human homolog receptors, CTLA-4 and CD28, both soluble ligands possessed greater affinity for CTLA-4, compared to CD28.
5837 16184234 In the case of cytokines production were observed that interferon (IFN-gamma) and interlukin (IL-2) were significantly enhanced, while IL-4 and IL-10 was almost unchanged to make comparison between primary and secondary infection at 12 Gy irradiation dose.
5838 16184234 Up-regulation of Th1 type cytokines, IFN-gamma and IL-2 may be affected to develop vaccine by irradiated MC.
5839 16184234 In the case of cytokines production were observed that interferon (IFN-gamma) and interlukin (IL-2) were significantly enhanced, while IL-4 and IL-10 was almost unchanged to make comparison between primary and secondary infection at 12 Gy irradiation dose.

5841 16185742 Post-depletion, CD8 cells expanded in the presence of higher levels of neutralizing Ab and CD4 help than post-challenge and had superior maturational characteristics as measured by expression of the anti-apoptotic protein Bcl-2, the IL-7 receptor CD127 and co-production of IFN-gamma and IL-2.
5842 16186817 Recently activated, but not resting, CD4(+) T cells express CD154, providing costimulatory signals to B cells and antigen-presenting cells (APCs).
5843 16186817 Therefore, de novo CD154 expression after stimulation identifies antigen-specific CD4(+) T cells.
5844 16186817 Using this assay, we found that stimulated cells expressing tumor necrosis factor (TNF)-alpha, interleukin (IL)-2 or interferon (IFN)-gamma were predominantly CD154(+).
5845 16186817 For vaccine- or pathogen-specific responses, we found substantial heterogeneity in expression of CD154 and cytokines, suggesting previously unrecognized diversity in abilities of responding cells to stimulate APCs through CD40.
5846 16195934 The recombinant porcine IL-2 expressed in the prokaryotic cells was found to be of 43 kDa molecular mass, which was consistent with a 17.4 kDa protein deduced from the IL-2 cDNA sequence (glutathione S-transferase molecular mass is 26 kDa); the recombinant protein in eukaryotic cells was confirmed by use of specific rabbit anti-porcine IL-2 serum in an ELISA.

5849 16210663 Expression of NKG2D ligands, Rae1, and H60 on SCC VII/SF cells was also examined.
5850 16210663 NK cells from tumor-bearing mice expressed significantly lower levels of NKG2D and CD16 compared with rvv-IL-2 vaccinated mice.
5851 16210663 Incubation of NK cells with tumor homogenate or cultured supernatant of SCC VII/SF cells reduced the expression of NKG2D and CD16.
5852 16210663 SCC VII/SF tumors in the oral cavity of the mice secrete high quantities of TGF-beta1, which reduce the expression of NK cell receptor NKG2D as well as CD16 and inhibits biological functions of NK cells.
5853 16216394 DNA vaccine using hemagglutinating virus of Japan-liposome encapsulating combination encoding mycobacterial heat shock protein 65 and interleukin-12 confers protection against Mycobacterium tuberculosis by T cell activation.
5854 16216394 We investigated the immunogenicity and protective efficacy of DNA vaccine combinations expressing mycobacterial heat shock protein 65 (Hsp65) and interleukin-12 (IL-12) using gene gun bombardment and the hemagglutinating virus of Japan (HVJ)-liposome method.
5855 16216394 A mouse IL-12 expression vector (mIL-12 DNA) encoding single-chain IL-12 proteins comprised of p40 and p35 subunits were constructed.
5856 16216394 In a mouse model, a single gene gun vaccination with the combination of Hsp65 DNA and mIL-12 DNA provided a remarkably high degree of protection against challenge with virulent Mycobacterium tuberculosis; bacterial numbers were 100-fold lower in the lungs compared to BCG-vaccinated mice.
5857 16216394 To explore the clinical use of the DNA vaccines, we evaluated HVJ-liposome encapsulated Hsp65 DNA and mIL-12DNA (Hsp65 + mIL-12/HVJ).
5858 16216394 Hsp65 + mIL-12/HVJ induced CD8+ cytotoxic T lymphocyte activity against Hsp65 antigen.
5859 16216394 Most importantly, Hsp65+mIL-12/HVJ vaccination resulted in a greater degree of protection than that evoked by BCG.
5860 16216394 This protective efficacy was associated with the emergence of IFN-gamma-secreting T cells and activation of proliferative T cells and cytokines (IFN-gamma and IL-2) production upon stimulation with Hsp65 and antigens from M. tuberculosis.
5861 16216394 These results suggest that Hsp65 + IL-12/HVJ could be a promising candidate for a new tuberculosis DNA vaccine, which is superior to BCG vaccine.
5862 16219395 However, the alum + MDP combination afforded higher antigen-specific recall responses in splenocyte cultures, associated with elevated release of the type I immune response cytokines IFN-gamma and IL-2.

5895 16249392 These leukemia-reactive T cells included both T-cytotoxic/T-helper 1 (Th1) and Th2 subclasses, as determined from their production of granzyme B, interferon-gamma, and interleukin-5.
5896 16249392 Immunotherapy of high-risk acute leukemia with a recipient (autologous) vaccine expressing transgenic human CD40L and IL-2 after chemotherapy and allogeneic stem cell transplantation.
5897 16249392 CD40L generates immune responses in leukemia-bearing mice, an effect that is potentiated by IL-2.
5898 16249392 We studied the feasibility, safety, and immunologic efficacy of an IL-2- and CD40L-expressing recipient-derived tumor vaccine consisting of leukemic blasts admixed with skin fibroblasts transduced with adenoviral vectors encoding human IL-2 (hIL-2) and hCD40L.
5899 16249392 Ten patients (including 7 children) with high-risk acute myeloid (n = 4) or lymphoblastic (n = 6) leukemia in cytologic remission (after allogeneic stem cell transplantation [n = 9] or chemotherapy alone [n = 1]) received up to 6 subcutaneous injections of the IL-2/CD40L vaccine.
5900 16249392 These leukemia-reactive T cells included both T-cytotoxic/T-helper 1 (Th1) and Th2 subclasses, as determined from their production of granzyme B, interferon-gamma, and interleukin-5.
5901 16253404 In order to optimize the procedure and test for its efficacy in more clinically relevant large animal models, we examined the detailed immune responses in rhesus macaques after vaccination intramuscularly with electroporation using the plasmid encoding for HBV preS(2)-S antigen and an adjuvant plasmid encoding for hIL-2 and hIFN-gamma.
5902 16260072 Both PHA- and FLU-induced proliferation were reduced in elderly subgroups.
5903 16260072 IL-2 and IFN-gamma levels did not change after vaccination of elderly, regardless of race.
5904 16266314 The secretion of IL-2 and IFN-gamma was also significantly increased by pgD and pMIP-1alpha co-injection; however, the production of cytokines IL-4 and IL-10 was not affected by co-injection. pgD and pMIP-1alpha co-injection resulted in a moderate enhancement of systemic gD-specific antibody level, but mucosal secretory IgA was markedly enhanced.
5905 16270154 The results showed that P6 (73-86 aa) generated the strongest stimulation effect on T cells among the nine candidate peptides, and drove the highest level of IFN-gamma and IL-2.
5906 16272299 These cells produced IL-2 and MIP-1alpha, but much less IL-4 and IFN-gamma than CD73- Ly6A/E+ cells.
5907 16272299 Restimulation of Thpp-like CD73+ Ly-6A/E- cells in Th1- or Th2-polarizing conditions induced differentiation into populations producing mainly IFN-gamma or mainly IL-4, respectively.
5908 16272299 In contrast, the effector-like CD73- Ly-6A/E+ population was more committed, and continued to produce both IL-4 and IFN-gamma in both conditions.
5909 16275627 Chlorophyllin attenuates IFN-gamma expression in lipopolysaccharide-stimulated murine splenic mononuclear cells via suppressing IL-12 production.
5910 16275627 RT-PCR analysis showed that LPS-activated IFN-gamma expression gradually declined by CHL treatment in a dose dependent manner while mRNA production of TNF-alpha, IL-2, and FasL was not changed.
5911 16275627 CHL also suppressed IL-12 production (p70, a heterodimer of p40 and p35) and the mRNA expression of IL-12 p40 and IL-12 receptors (both IL-12Rbeta1 and IL-12Rbeta2), which are involved in the induction of IFN-gamma expression.
5912 16275627 Furthermore, an electrophoretic mobility shift assay showed that CHL inhibited DNA binding activity of NF-kappaB, STAT-3, and STAT-4 to their cognate DNA recognition motifs, all of which contribute to the IL-12-induced IFN-gamma transcription.
5913 16275627 Exogenous addition of recombinant IL-12 abrogated the inhibitory effect of CHL on IFN-gamma and its mRNA expression in LPS-activated splenocytes.
5914 16275627 Collectively, these results show that CHL inhibits IFN-gamma production by LPS-stimulated splenic mononuclear cells due to down-regulation of IL-12 production.
5915 16275895 Bovine natural killer (NK) cells were recently identified by positive selection of a NK cell-activating receptor p46 (NKp46)+ CD3- lymphocyte population, which expresses CD25 and CD8 and lyses tumor cell lines following stimulation with recombinant interleukin-2.
5916 16275895 In the current work, we characterize the cytotoxic/effector potential of a CD3(-)CD8(-)CD11b- population isolated through negative selection of bovine peripheral blood leukocytes.
5917 16275895 This population is CD25(lo)CD62(hi) when isolated and becomes CD25hiCD62L(lo) following cytokine stimulation.
5918 16275895 Activated bovine NK cells increase expression of granulysin, interferon-gamma, and perforin and have cytotoxic activity against human tumor cells and Mycobacterium bovis bacillus Calmette-Guerin-infected alveolar and monocyte-derived macrophages.
5919 16275895 Expression of a bovine homologue of the CD56 neural adhesion molecule expressed by human NK cells was detected in mRNA from brain tissue but was not detected in peripheral blood mononuclear cells or purified NK cell mRNA.
5920 16275895 Analysis of mRNA from nonstimulated peripheral blood NK cells demonstrates the constitutive expression of homologues of human NK receptors NKp46, CD244, and CD94 and the granule proteins granulysin and perforin.
5921 16275895 Phorbol ester-stimulated CD8+ T cells also expressed CD244 and CD94, and CD4+ T cells expressed CD94.
5922 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.
5923 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).
5924 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.
5925 16279537 The content of IL-2 and IL-10 remained unchanged.
5926 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.
5927 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.
5928 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.
5929 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.
5930 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.
5931 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.

5934 16301632 Peripheral tolerance is maintained in part by thymically derived CD25+CD4+ T cells (regulatory T cells (Tregs)).
5935 16301632 Visualization of this time frame, using a sensitive single-cell assay for IL-2, revealed the early elaboration of target cell IL-2 producers in the first 6 h despite the presence of CD25+CD4+ Tregs.
5936 16301632 Modulating target T cell activation signals with provision of CD28, IL-2, or high Ag dose all abrogated suppression of proliferation late in culture.
5937 16301632 However, only CD28 signals enabled target T cells to resist the early Treg-induced down-regulation of IL-2.

5946 16305402 A ten-fold lower dose (0.5 microg instead of 5 microg) of CpG ODN in nanoparticles was adequate to obtain levels of IFN-gamma, TNF-alpha, and IL-2 comparable to those observed following immunisations in saline.
5947 16306607 Following boosting with live attenuated virus, control of Deltanef replication was superior in SIV-DNA-primed macaques versus vector-DNA-primed macaques and was correlated with higher levels of CD8+/gamma-interferon-positive and/or interleukin-2-positive cells.
5948 16308572 In this study, we investigated whether elimination of CD4+/CD25+ Tregs using the recombinant IL-2 diphtheria toxin conjugate DAB(389)IL-2 (also known as denileukin diftitox and ONTAK) is capable of enhancing the immunostimulatory efficacy of tumor RNA-transfected DC vaccines.
5949 16314006 Specific IgG prevents enteroinvasive Escherichia coli/Salmonella typhi-induced diarrhea and may exert an effective protection by enhancing splenic NK cell activity, elevating IL-2 level and inhibiting excessive release of TNF-alpha in mice.

5954 16339537 IL-2 regulates perforin and granzyme gene expression in CD8+ T cells independently of its effects on survival and proliferation.
5955 16339537 We show in this study that IL-2 increased the expression of perforin and granzyme A, B, and C mRNA; intracellular granzyme B protein levels; and cytolytic function in a dose-dependent manner during primary activation of murine CD8+ T cells in vitro.
5956 16339537 First, IL-2 enhancement of perforin and granzyme expression was equivalent in CD8+ T cells from wild-type and bcl-2 transgenic mice, although only the latter cells survived in low concentrations or the absence of added IL-2.
5957 16339537 This property of bcl-2 transgenic T cells also allowed the demonstration that induction of granzyme A, B, and C mRNA and granzyme B protein required exogenous IL-2, whereas induction of perforin and IFN-gamma expression did not.
5958 16339537 Together, these findings indicate that IL-2 can directly regulate perforin and granzyme gene expression in CD8+ T cells independently of its effects on cell survival and proliferation.

5979 16353546 This type of response involves participation of alveolar macrophages and T CD4+, CD8+ and T gammadelta lymphocytes, and production of cytokines such as IL-2, IFN-gamma, IL-12, IL-18 and TNF-alpha, as well as chemokines such as RANTES, MCP-1, MIP-1alpha and IL-8 which play an important role in the migration of different cell subpopulations to the infection site for the formation of granulome.
5980 16369009 Gerbils vaccinated with CpG-ODN and Gal-lectin also had significantly higher levels of gamma interferon, interleukin-12 (IL-12), and IL-2 mRNA than controls.
5981 16375942 Th1 CD4 T cell responses were also detected in VP6-immunized animals based on high levels of IFN-gamma and IL-2 found after in vitro VP6 stimulation of spleen cells.
5982 16388819 Rapid qualitative and quantitative analysis of T-cell responses in HIV-1-infected individuals receiving successful HAART and HIV-1 sero-negative controls: concomitant assessment of perforin, IFN-gamma and IL-4 secretion.
5983 16388819 We describe here for the first time a perforin-release ELIspot assay which, when used in combination with IFN-gamma and IL-4 ELIspots, permits rapid assessment of these functional parameters for antigen-specific T cells.
5984 16388819 Tetanus toxoid stimulation was associated with moderate perforin release and a predominantly type-2 IL-4 producing response, whilst herpes simplex virus antigen stimulation resulted in perforin release but only a weak type-1 IFN-gamma response.
5985 16388819 Cytokines IL-2 and IL-12/IL-15 induced perforin release coupled with an IFN-gamma type-1 response.
5986 16388819 Perforin release strongly correlated with IFN-gamma production to individual influenza, Epstein-Barr virus or cytomegalovirus MHC class I restricted peptides, in an HIV-1 sero-negative cohort, indicating a cytolytic type-1 CD8+ T-cell response.
5987 16388819 Evaluation of immunogenicity and putative efficacy of candidate vaccines using IFN-gamma will not be as informative alone as when combined with perforin and IL-4 evaluations, which allow assessment of specific cytotoxic potential without extensive cell culture.
5988 16397274 Tumor-derived interleukin-4 reduces tumor clearance and deviates the cytokine and granzyme profile of tumor-induced CD8+ T cells.
5989 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.
5990 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.
5991 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.
5992 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.
5993 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.
5994 16406172 Noteworthy, also an induced temporary release of cytokines including IFNgamma and IL-2, indicative for T-cell activation, was measured.
5995 16409137 Checkpoints being targeted include CTLA-4 and PD1 that are negative signaling receptors expressed on activated T cells, CD4+CD25+ Foxp3-expressing Tregs (suppressor T cells), IL-2-mediated activation-induced cell death (AICD), and the cytokine TGFbeta.
5996 16415106 Transfer of regulatory T cells generated ex vivo modifies graft rejection through induction of tolerogenic CD4+CD25+ cells in the recipient.
5997 16415106 Certain CD4+CD25+ T cells can induce and maintain T-cell non-responsiveness to donor alloantigens and have therapeutic potential in solid organ transplantation.
5998 16415106 Peripheral CD4+CD25- cells alloactivated with IL-2 and transforming growth factor beta (TGF-beta) ex vivo express the transcription factor FoxP3, and become potent antigen-specific CD4+CD25- suppressor cells.
5999 16415106 Here we report that the transfer of TGF-beta-induced regulatory CD4+ and CD8+ T cells (Tregs) co-incident with transplantation of a histoincompatible heart resulted in extended allograft survival.
6000 16415106 To account for this result, we injected non-transplanted mice with a single dose of CD4+ and CD8+ Tregs and transferred donor cells every 2 weeks to mimic the continuous stimulation of a transplant.
6001 16415106 We observed increased splenic CD4+CD25+ cells that were of recipient origin.
6002 16415106 Both the increased number of CD4+CD25+ cells and their tolerogenic effect were dependent on continued donor antigen boosting.
6003 16417908 Different response requirements for IFNgamma production in ELISPOT assays by CD4+ T cells from mice early and late after immunization.
6004 16417908 The present study focused on detecting changes in production of IFNgamma by CD4+ T cells over time during chronic antigen exposure.
6005 16417908 To assay the CD4+ T cell response to HBcAg, splenocytes from immunized mice were restimulated with rHBcAg for 24 or 48 h in vitro and tested for IFNgamma and IL-5 secreting cells by ELISPOT.
6006 16417908 This delay in IFNgamma production was related to the availability of IL-2, since addition of IL-2 allowed the delayed cells from late responses to develop peak IFNgamma production in vitro by 24 h, equivalent to that of cells from early responses.
6007 16417908 This IL-2 dependent delay occurred in Th1-type IFNgamma responses but not in Th2-type IL-5 responses.
6008 16417908 These observations indicate that, when detecting IFNgamma secreting cells it is important to screen responses at different times of restimulation or in the presence and absence of IL-2 to ensure optimal detection.

6019 16417908 This IL-2 dependent delay occurred in Th1-type IFNgamma responses but not in Th2-type IL-5 responses.
6020 16417908 These observations indicate that, when detecting IFNgamma secreting cells it is important to screen responses at different times of restimulation or in the presence and absence of IL-2 to ensure optimal detection.
6021 16423399 After lymphocytes were stimulated with 10mug/ml purified N antigen, The CD4+ and CD8+ T cells of N and M plus N group were increased compared with those of control groups, and the M protein could augment the activation of lymphocytes induced by N DNA vaccine.
6022 16423399 Cytokine ELISA analysis revealed that co-injection of M could enhance the levels of IFN-gamma, IL-2 release induced by N antigen.
6023 16424174 Protein vaccines induce uncommitted IL-2-secreting human and mouse CD4 T cells, whereas infections induce more IFN-gamma-secreting cells.
6024 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.
6025 16424174 However, primed CD4 T cells can also remain uncommitted, secreting IL-2 and chemokines, but not IFN-gamma or IL-4.
6026 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.
6027 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.

6029 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.
6030 16424174 Protein vaccines induce uncommitted IL-2-secreting human and mouse CD4 T cells, whereas infections induce more IFN-gamma-secreting cells.

6065 16424205 IL-21 is an IL-2-like cytokine, signaling through a specific IL-21R and the IL-2R gamma-chain.
6066 16424205 We tested whether the low therapeutic outcome might be due to CD4+CD25+ regulatory T cells (Treg) present in TS/A-pc tumors and draining lymph nodes and whether IL-21 had any effect on these cells.
6067 16424205 Indeed, CD4+CD25+ cells suppressed IFN-gamma production by splenocytes from immune mice in response to stimulation by the AH1 peptide.
6068 16424205 Low concentrations of IL-21 (10 ng/ml) failed to reverse the inhibitory activity of CD4+CD25+ cells in an allogeneic MLR, whereas 60 ng/ml rIL-21 partially restored responder T cell proliferation.
6069 16424205 Successful combined immunotherapy required NK cells, CD8+ T cells, and IFN-gamma.
6070 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.
6071 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.
6072 16425224 In this study, the treatment with heat shock protein 70 (HSP70) vaccine induced an infiltration of T cells into the tumor site as well as the expression of IFN-gamma and IL-2, and delayed lung metastases of tumor, but the tumor progression nonetheless occur finally.
6073 16425224 To complement these findings, we investigated the gene expression of tumor-infiltrating lymphocytes (TILs) by Real-time PCR analysis, which revealed that the expression of TH1 cytokines IFN-gamma and IL-2 by TIL in the mice treated with HSP70 vaccine in combination with sPD-1 was increased and the expression of negative regulatory molecules IL-10, TGF-beta and foxp3 was decreased, demonstrating that multifunctional properties afforded by the combination therapy can effectively overcome tumor resistance and promote effective antitumor immunity.

6076 16425996 Asymptomatic, antiretroviral-treatment-naïve, HIV-1-infected patients with CD4(+) T-cell counts greater than 400/microl received multiple intramuscular injections of HIV-1 IIIB recombinant envelope glycoprotein (rgp160) vaccine or HIV-1 MN recombinant envelope glycoprotein (rgp120) vaccine (eight patients, referred to as the HIV-1 vaccinees) or placebo or hepatitis B vaccine (three patients, referred to as the controls).
6077 16425996 In flow cytometric analyses of intracellular cytokines, T-cell receptor stimulation with an anti-CD3 antibody induced gamma interferon (IFN-gamma) expression by activated CD4(+) and CD8(+) lymphocytes at greater frequencies than did stimulation with recombinant envelope glycoprotein and p24 of HIV-1 (P < 0.05).
6078 16425996 Mean frequencies of HIV-1 envelope glycoprotein-stimulated, activated intra-cellular IFN-gamma-producing CD4(+) and CD8(+) lymphocytes and of interleukin-2-producing CD4(+) lymphocytes did not increase after vaccination, but cytokine-producing cells were detectable in some patients.
6079 16425996 Comparing pre- to post-HIV-1 vaccination time points, changes in frequencies of activated, IFN-gamma-producing CD4(+) cells correlated inversely with changes in lymphocyte proliferation in response to recombinant envelope glycoprotein in HIV-1 vaccinees (P < 0.05).
6080 16442639 This approach generated immortalized antigen-specific CD4+ and CD8+ T-cell lines that maintained strictly IL-2-dependent growth and HLA-restricted, antigen-specific responsiveness, some of which have been in continuous culture for longer than 1 year, far in excess of the survival of parallel control non-immortalized cultures.
6081 16446012 The immune-stimulating activity was studied by measuring anti-HBsAg titre, secretory IgA level in serum, vaginal, nasal and salivary secretions (mucosal secretions) and cytokine level (interleukin-2 (IL-2) and interferon-gamma (IFN-gamma)) in spleen homogenates following nasal administration of modified PLGA microspheres in Balb/c mice and compared with alum-HBsAg vaccine injected subcutaneously.

6083 16446171 The Cu-Zn superoxide dismutase (SOD) antigen of Brucella abortus was previously identified to be a T cell antigen which induces both proliferation of and gamma interferon (IFN-gamma) secretion by T cells from infected mice.
6084 16446171 In this study, we evaluated the effect of delivering IL-2 on the efficacy of SOD DNA vaccine by generating a plasmid (pSecTag-SOD-IL2) that codes for a secretory fusion protein of SOD and IL-2.
6085 16446171 Upon in vitro stimulation with recombinant SOD (rSOD) antigen, T cells from mice immunized with pSecTag-SOD-IL2, in comparison with those from mice immunized with pSecTag-SOD, exhibited a lower proliferation response but produced significantly higher concentrations of IFN-gamma.
6086 16446171 These results suggest that a SOD DNA vaccine fused to IL2 did not improve protection efficacy.

6097 16467198 Here, we assess the quality of the HIV-specific CD8(+) T-cell response by measuring 5 CD8(+) T-cell functions (degranulation, IFN-gamma, MIP-1beta, TNF-alpha, and IL-2) simultaneously in chronically HIV-infected individuals and elite nonprogressors.
6098 16477768 In intensified-diet calves, percentages of CD4+ expressing interleukin-2 receptor increased and percentages of gamma delta TCR+ cells expressing interleukin-2 receptor decreased with time.
6099 16477768 Percentages of CD4+ and CD8+ T cells, and B cells expressing MHC class II antigen, were unaffected by diet or age.
6100 16478885 Foxp3+CD4+CD25+ T cells control virus-specific memory T cells in chimpanzees that recovered from hepatitis C.
6101 16478885 CD4(+)CD25(+) T cells have been implicated in HCV persistence because their frequency is increased in the blood of HCV-infected patients and their in vitro depletion results in increased IFN-gamma production by HCV-specific T cells.
6102 16478885 Studying a well-characterized cohort of 16 chimpanzees, the sole animal model for HCV infection, we here demonstrate that the frequency of Foxp3(+)CD4(+)CD25(+) regulatory T cells (T(Regs)) and the extent of suppression was as high in spontaneously HCV-recovered chimpanzees as in persistently HCV-infected chimpanzees.
6103 16478885 Foxp3(+)CD4(+)CD25(+) T(Regs) suppressed IFN-gamma production, expansion, and activation-induced cell death of HCV-specific T cells after recovery from HCV infection and in persistent HCV infection.
6104 16478885 However, Foxp3(+)CD4(+)CD25(+) T(Reg) cells of both HCV-recovered and HCV-infected chimpanzees differed from Foxp3(+)CD4(+)CD25(+)T(Reg) cells of HCV-naive chimpanzees in increased IL-2 responsiveness and lower T-cell receptor excision circle content, implying a history of in vivo proliferation.
6105 16478885 This result suggests that HCV infection alters the population of Foxp3(+)CD4(+)CD25(+) T(Reg) cells.
6106 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.
6107 16494975 Furthermore, flow cytometric analyses showed elevated numbers of CD4+ lymphocytes expressing IFN-gamma and IL-2 against the ESAT-6 peptides, suggesting a specific Th1-mediated response.
6108 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.
6109 16505141 DEC-205-targeted HIV gag p24 or p41 induces stronger CD4+ T cell immunity relative to high doses of gag protein, HIV gag plasmid DNA, or recombinant adenovirus-gag.
6110 16505141 High frequencies of interferon (IFN)-gamma- and interleukin 2-producing CD4+ T cells are elicited, including double cytokine-producing cells.
6111 16505141 After subcutaneous vaccination, CD4+ and IFN-gamma-dependent protection develops to a challenge with recombinant vaccinia-gag virus at a mucosal surface, the airway.
6112 16512177 The increase in the detected significant immunological parameters (total IgE, IgG, IL-2, CD4+, CD8+, and CB16+ cells) was ascertained to supplement the traditional methods for tuberculin diagnosis.
6113 16516674 Therapies under investigation include topical retinoids, fusion molecules like denileukin diftitox, pegylated interferon, interleukin-2, and interleukin-12.
6114 16522814 We found that while SIV-specific T-cell responses are detectable in the majority of animals, their magnitude and breadth are, in fact, lower than what has been described in HIV-infected humans, both in terms of cytokine production (ie, IFN-gamma, TNF-alpha, and IL-2) and degranulation (ie, CD107a expression).
6115 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.
6116 16556474 Mutant Escherichia coli enterotoxin as a mucosal adjuvant induces specific Th1 responses of CD4+ and CD8+ T cells to nasal killed-bacillus calmette-guerin in mice.
6117 16556474 Spleen cells, particularly CD4+ T cells among them produced IL-2, IFNgamma and TNFalpha in response to the killed-BCG or purified protein derivatives.
6118 16556474 CD8+ T cells including cytotoxic T lymphocytes produced IFNgamma and TNFalpha.
6119 16556474 CD4+ and CD8+ T cells produce cytokines effective for tuberculosis.
6120 16563545 Moreover, p24/PLA nanoparticles elicited strong CTL responses and a Th1-biased cytokine release (IFNgamma, IL-2) in mice. p24 protein seemed to generate a more Th1-oriented response when administered coated onto the surface of PLA nanoparticles than adjuvanted with Freund's adjuvant.
6121 16563545 Most importantly, the ability of p24/PLA particles to induce Th1 responses was also confirmed in the macaque model, since high levels of IFNgamma-producing CD4+ T cells and CD8+ T cells could be detected by the ELISPOT assay.
6122 16580736 CD28 and ICOS: similar or separate costimulators of T cells?
6123 16580736 Numerous studies have revealed that the B7.1/B7.2-CD28 and B7RP-1-ICOS (Inducible COStimulator) pathways provide crucial costimulatory signals to T cells.
6124 16580736 This comparison between CD28 an ICOS after initiation of T cell activation demonstrates that both CD28 and ICOS function similarly during expansion, survival and differentiation of T cells and that both CD28 and ICOS are necessary for proper IgG responses.
6125 16580736 The major differences between CD28 and ICOS are differences in expression of both receptors and ligands, and the fact that CD28 induces IL-2 production, whereas ICOS does not.
6126 16580736 In addition, ICOS is more potent in the induction of IL-10 production, a cytokine important for suppressive function of T regulatory cells.
6127 16585561 We have investigated how IFN-alphabeta induces cross-priming, comparing CD8+ T cell responses generated against soluble protein Ags in the presence or absence of IFN-alphabeta.
6128 16585561 Injection of IFN-alpha was found to prolong the proliferation and expansion of Ag-specific CD8+ T cells, which was associated with marked up-regulation of IL-2 and IL-15 receptors on Ag-specific cells and expression of IL-15 in the draining lymph node.
6129 16585561 Surprisingly, neither IL-2 nor IL-15 was required for IFN-alpha-induced cross-priming.
6130 16585561 We have investigated how IFN-alphabeta induces cross-priming, comparing CD8+ T cell responses generated against soluble protein Ags in the presence or absence of IFN-alphabeta.
6131 16585561 Injection of IFN-alpha was found to prolong the proliferation and expansion of Ag-specific CD8+ T cells, which was associated with marked up-regulation of IL-2 and IL-15 receptors on Ag-specific cells and expression of IL-15 in the draining lymph node.
6132 16585561 Surprisingly, neither IL-2 nor IL-15 was required for IFN-alpha-induced cross-priming.

6137 16585571 CD4 T cells were stimulated with Ag presented by B7-negative APC and CD28 costimulation was provided in trans by anti-CD28-coated beads or by class II-negative, B7-positive cells.
6138 16585571 We show that induction of IL-2 secretion under these conditions did not require expression of PKCtheta and did not induce NF-kappaB activation or IL-2 transcription.
6139 16585571 In contrast, CD28 costimulation in trans did induce IL-2 mRNA stability, accounting for the up-regulation of IL-2 secretion.
6140 16585571 These data indicate that the ability of CD28 to up-regulate IL-2 transcription requires colocalization of TCR and CD28 at the plasma membrane, possibly within the cSMAC of the immunological synapse.
6141 16585571 In contrast, the ability of CD28 to promote IL-2 mRNA stability can be transduced from a distal site from the TCR, suggesting that signal integration occurs downstream from the plasma membrane.

6196 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.
6197 16616574 Immunization with MIC1 and MIC4 induces protective immunity against Toxoplasma gondii.
6198 16616574 In this work, we evaluated the protective effect encountered in C57BL/6 mice immunized with MIC1 and MIC4 purified from soluble tachyzoite antigens by affinity to immobilized lactose.
6199 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.
6200 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.
6201 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.
6202 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.
6203 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.
6204 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.
6205 16690096 In this study, we found that peripheral blood mononuclear cells (PBMCs) from fully recovered SARS individuals rapidly produced IFN-gamma and IL-2 following stimulation with a pool of overlapping peptides that cover the entire N protein sequence.
6206 16690096 The N-specific IFN-gamma(+)CD4(+) T cells were mainly composed of CD45RA(-)CCR7(+)CD62L(-) cells, whereas IFN-gamma(+)CD8(+) memory T cells were mostly contained within CD45RA(+)CCR7(-)CD62L(-) cell population.
6207 16691294 IL-15 induces CD4 effector memory T cell production and tissue emigration in nonhuman primates.
6208 16691294 Here, we demonstrate that IL-15 dramatically increases in vivo proliferation of rhesus macaque (RM) CD4+ and CD8+ T EM cells with little effect on the naive or central memory T (T CM) cell subsets, a response pattern that is quite distinct from that of either IL-2 or IL-7.
6209 16691294 In RMs with uncontrolled SIV infection and highly activated immune systems, IL-15 did not significantly increase CD4+ T EM cell proliferation, but with virologic control and concomitant reduction in immune activation by ART, IL-15 responsiveness was again observed.
6210 16691294 These data suggest that therapeutic use of IL-15 in the setting of ART might facilitate specific restoration of the CD4 + T cell compartment that is the primary target of HIV with less risk of exhausting precursor T cell compartments or generating potentially deleterious regulatory subsets.
6211 16697684 BLS-KETc1 also increased the levels of transcription of TNF-alpha, IL-2 and IFNgamma in Peyer's patches, and in spleen, only increased TNF-alpha was observed.
6212 16698679 To assess GM-CSF immune accessory effects in tumor-bearing mice, an animal tumor model was established by inoculating SP2/0 myeloma cells s.c. into the flank of Balb/c mice and 14 days later, injecting either 400 mug recombinant pcDNA3.1/mGM-CSF or a blank plasmid s.c. or i.m. into the tumor four times.
6213 16698679 The tumor weight, the activities of CTL and NK, the serum levels of IFN-gamma, IL-2 and lymphocytes infiltrating in tumor tissue were analysed 8 weeks later with MTT, ELISA and pathological section methods.
6214 16698679 In addition, the serum concentrations of IFN-gamma, IL-2 and the activities of CTL and NK cells were significantly increased in mice injected with pcDNA3.1/mGM-CSF compared with a control mice (P < 0.01).

6218 16710741 Our results showed that vaccination with CRT180/HPV6bE7 or CRT120/HPV6bE7 enhanced the presence of CD8(+) T cells and TCRgammadelta T cells in vivo, increased the specific lysis activity against E7-expressing cells and secretion levels of IL-2 and IFN-gamma by activating T cells in vitro significantly.
6219 16712895 Levels of interleukin-10 (IL-10) produced by peripheral blood mononuclear cells (PBMC) seemed to inversely correlate with interferon-gamma responses.
6220 16712895 IL-2, IL-4 or transforming growth factor-beta responses were not detected at any time for neither of the vaccines.
6221 16712895 These results indicated a strong involvement of IFN-gamma, and maybe IL-10, in the development of immunity against PRRS virus.
6222 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.
6223 16762359 Using this method, we directly identify differences in IL-2 production capacity by CD62L(hi)- and CD62L(lo)-expressing antigen-specific memory CD8 T cell populations.

6225 16779722 The J8R(11-19)-specific CTL line and CTL clone exerted physiologically relevant functions as they recognized VV-infected lymphoblastoid JY cells or autologous B lymphoblastoid cell lines, and the cytolytic activity was accompanied by the production of interferon- gamma , tumor necrosis factor- alpha , and interleukin-2.
6226 16787189 Studies in small animal model systems have shown that ex vivo transduction of irradiated tumor cells with amplicon vectors encoding immunomodulatory cytokines such as IL-2 or GM-CSF can elicit protective responses against a tumor challenge.

6229 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).
6230 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.
6231 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.
6232 16815096 The spleen tissues from guinea pigs vaccinated with recombinant BCG Tokyo or Ag85A DNA expressed IFN-gamma and IL-2 mRNA at significantly high levels (p<0.001) as evaluated by reverse transcription polymerase chain reaction.
6233 16830050 Two agents, DAB389IL-2 (ONTAKTM) targeting the interleukin-2 receptor and CD33-calicheamicin (Mylotarg), have been approved by the FDA for cutaneous T-cell lymphoma (CTCL) and relapsed acute myeloid leukemia (AML), respectively.

6242 16887240 The results showed that two cCHMIs, whether single or cooperative injection with IL-2, could significantly raise the antibody titers, while immunologic synergisms of two cCHMIs with IL-2 were unconspicuous. cCHMs 1 at three doses and cCHMIs 2 at high dose could remarkably promote the expression of IL-2 mRNA in chicken T lymphocyte, two cCHMIs at three doses, the expression of IFN-gamma mRNA, which could explain why the immunologic synergism of cCHMIs with IL-2 was not obvious.

6251 16907905 These family strains have developed mechanisms that modulate/suppress immune responses by the host, such as inhibition of apoptosis of infected macrophages, diminished production of interleukin (IL)-2, interferon (IFN)-gamma, tumour necrosis factor (TNF)-alpha and elevated levels of IL-10 and IL-18.
6252 16927109 Further developments such as treatment with recombinant cytokines (especially IL-2 and GM-CSF), specific blockade of neoplastic signal transduction and vaccination are the central issues in current research.
6253 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).
6254 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.
6255 16943292 We have recently shown that survival in plasmid DNA-primed/recombinant adenovirus-boosted rhesus monkeys that are challenged with the simian immunodeficiency virus SIVmac251 is associated with the preservation postchallenge of central memory CD4(+) T lymphocytes and robust gamma interferon (IFN-gamma)-producing SIV-specific CD8(+) and CD4(+) T-lymphocyte responses.
6256 16943292 We show that the preservation of the SIV-specific central memory CD8(+) T-lymphocyte population and a linked SIV-specific CD4(+) T-lymphocyte response are associated with prolonged survival in vaccinated monkeys following challenge.
6257 16943292 Furthermore, we demonstrate that SIV-specific IFN-gamma-, tumor necrosis factor alpha-, and interleukin-2-producing T lymphocytes are all comparably associated with protection against disease progression.
6258 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.
6259 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.
6260 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.

6285 16971432 Interestingly, the mucosal immunoglobulin A (IgA) and CD8(+) T-cell responses in the respiratory compartment could be restored in aged mice primed with the IL-2-expressing virus to magnitudes similar to those in young adult mice.
6286 16971432 The immunomodulating effect of locally expressed IL-2 also gave rise to a systemic CD8(+) T-cell and distant urogenital IgA response in young adult mice, but this effect was less distinct in aged mice.

6294 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.
6295 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.
6296 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.
6297 16982932 A single stimulation of CD8+ T cells from healthy virus carriers, and patients with HL with this adenoviral construct in combination with IL-2, was sufficient to reverse the functional T cell impairment and restored both IFN-gamma production and cytolytic function.
6298 16982932 Flow cytometric analysis revealed that a large proportion of T cells expanded from patients with HL were CD62L(high) and CD27(high), and CCR7(low), consistent with early to mid effector T cells.
6299 16987070 Compared with oil adjuvant, the killed NDV in LMS+ induced a significantly higher helper T cell type 1 response, as shown by higher levels of interleukin-2, interferon-gamma, T cell proliferation, and delayed-type hypersensitivity responses, without sacrificing the level of IgG production in mice.
6300 16991124 Induction of protective immunity to RM-1 prostate cancer cells with ALVAC-IL-2/IL-12/TNF-alpha combination therapy.
6301 16991124 ALVAC recombinant canarypox viruses encoding interleukin-2, interleukin-12 and tumor necrosis factor-alpha were used to create therapeutic vaccines in 2 different ways.
6302 16991124 Tumor-free survival induced by the separate injection vaccine required natural killer (NK) cells, CD4(+), and CD8(+) T cells.
6303 16991124 Secondary clearance of tumors also required NK and CD8(+) T cells, but not CD4(+) T cells.

6307 16991124 Secondary clearance of tumors also required NK and CD8(+) T cells, but not CD4(+) T cells.
6308 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.
6309 17005692 CD127+CCR5+CD38+++ CD4+ Th1 effector cells are an early component of the primary immune response to vaccinia virus and precede development of interleukin-2+ memory CD4+ T cells.
6310 17005692 Between days 11 and 14 postinoculation, there was a peak of proliferating CCR5+CD38+++ CD4+ effector cells which contained the cytotoxic granule marker T-cell intracellular antigen 1 and included gamma interferon (IFN-gamma)-producing vaccinia virus-specific CD4+ T cells.
6311 17005692 The majority of these initial vaccinia virus-specific CD4+ T cells were CD127+ and produced interleukin-2 (IL-2) but not CTLA-4 in response to restimulation in vitro.
6312 17005692 Between days 14 and 21, there was a switch from IFN-gamma and IL-2 coexpression to IL-2 production only, coinciding with a resting phenotype and an increased in vitro proliferation response.
6313 17005692 The early CCR5+CD38+++ vaccinia virus-specific CD4+ T cells were similar to our previous observations of human immunodeficiency virus (HIV)-specific CD4+ T cells in primary HIV type 1 (HIV-1) infection, but the vaccinia virus-specific cells expressed much more CD127 and IL-2 than we previously found in their HIV-specific counterparts.

6339 17008080 It was observed that despite differential induction of Interleukin(IL)-12 and IL-10 production, identical IL-12/IL-10 concentration ratio was obtained by all Brucella strains DNAs that was 2 after 24 h and 4 after 5 days of incubation.
6340 17008080 In addition, IL-2 and Interferon(IFN)-gamma production were profoundly increased compared to the medium at day 3 and 5 respectively but IFN-alpha was not induced.
6341 17009044 The kinetics of the carbohydrate-specific IgG response correlated with a temporary release of cytokines such as IFNgamma, IL-2, IL-1beta, TNFalpha and GM-CSF which was measurable in the immune serum by xMAP Multiplex technology.
6342 17013989 Virus-specific CD4+ T cells with IL-2-secreting and/or proliferative capacity are detected readily in HIV-1-infected long-term nonprogressors and rarely in persons with untreated progressive infection.
6343 17013989 We determined the effect of vaccination with modified vaccinia virus Ankara (MVA) expressing HIV-1 gag p24/p17 (MVA.HIVA) on HIV-1-specific CD4+ T cell responses in 16 chronically infected, highly active antiretroviral therapy (HAART)-treated subjects using CD8-depleted IFN-gamma ELISPOT assays, intracellular cytokine staining assays for IL-2 and IFN-gamma, and a CFSE-based proliferation assay.
6344 17013989 The frequencies of CD4+ T cells expressing IL-2 or IFN-gamma, alone or simultaneously, were also augmented.

6351 17021999 Cells were cultured for 48 hours; following incubation, supernatants were collected and assayed for interleukin-2, interleukin-10, and interferon-gamma production, cytokines important in the immune response to viral infection.
6352 17021999 Four species ( E. angustifolia, E. purpurea, E. simulata, E. tennesseensis) augmented IL-10 production, diminished IL-2 production, and had no effect on IFN-gamma production.

6355 17027529 In HIV-infected patients, the IL-2/IL-2 receptor (IL-2R) system is dysregulated.
6356 17027529 The fact that IL-2 is underproduced along with defective IL-2R signaling detected in patient lymphocytes, may explain the progressive impairment of the immune system that occurs during chronic infection with this virus.
6357 17027529 However, in some patients IL-2R defects persist and the CD4 counts remain low despite good control of the viral load.

6361 17032167 These cytokines and chemokines included interleukin-12 (IL-12) and IL-18, as potent inducers of IFN-gamma, and IFN-gamma-inducible protein (IP-10), the production of which is IFN-gamma dependent.
6362 17032167 A coinjection of either IL-12 or IL-18 strongly suppressed the humoral antibody responses but increased the production of the Th1-type cytokines IFN-gamma and IL-2 from immune T cells.
6363 17032167 On the other hand, IP-10 exhibited enhanced immune responses in both antibody responses and IFN-gamma production of immune T cells and facilitated the prolonged survival of infected mice.
6364 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.
6365 17047396 The restimulated splenocytes demonstrated increased cytotoxic response, lymphocytic proliferation and elevated levels of Th type I cytokines (IL-2, IL-12, IFN-gamma and TNF-alpha).
6366 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.
6367 17055124 While the expression of Th2 type cytokine IL-10 was similar in all mice, IL-4 was not detected.
6368 17067728 Mice receiving a standard immunising dose of approximately 10(7) BCG (range, 1-5 x 10(7)) developed mycobacterial antigen-specific lymphocyte transformation (LT) responses, as well as interleukin-2 (IL-2) and gamma-interferon (IFN-gamma) secretion, at 8 and 18 weeks post-oral vaccination.
6369 17067728 Interestingly, while lymphocyte transformation and interleukin-2 responses remained largely unaltered in these mice, levels of IFN-gamma produced by antigen-stimulated lymphocytes were shown to be reduced significantly.
6370 17067728 Mice receiving a standard immunising dose of approximately 10(7) BCG (range, 1-5 x 10(7)) developed mycobacterial antigen-specific lymphocyte transformation (LT) responses, as well as interleukin-2 (IL-2) and gamma-interferon (IFN-gamma) secretion, at 8 and 18 weeks post-oral vaccination.
6371 17067728 Interestingly, while lymphocyte transformation and interleukin-2 responses remained largely unaltered in these mice, levels of IFN-gamma produced by antigen-stimulated lymphocytes were shown to be reduced significantly.
6372 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).
6373 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.
6374 17076705 Antibody depletion experiments showed that antituberculosis protective responses in the lung were not diminished by removal of CD8(+), T-cell receptor gammadelta (TCR-gammadelta(+)) and NK1.1(+) T cells from vaccinated CD4(-/-) mice before challenge, implying that the observed recall and immune effector functions resulting from vaccination of CD4(-/-) mice with mc(2)6030 were attributable to a population of CD4(-) CD8(-) (double-negative) TCR-alphabeta(+), TCR-gammadelta(-), NK1.1(-) T cells.
6375 17076705 Enriched pulmonary double-negative T cells transcribed significantly more interferon-gamma and interleukin-2 mRNA than double-negative T cells from naive mice after a tuberculous challenge.
6376 17076705 These results confirmed previous findings on the potential for a subset of MHC class II-restricted T cells to develop and function without expression of CD4 and suggest novel vaccination strategies to assist in the control of tuberculosis in human immunodeficiency virus-infected humans who have chronic depletion of their CD4(+) T cells.
6377 17082591 CD73 (5'-ectonucleotidase) is expressed by two distinct mouse CD4 T cell populations: CD25+ (FoxP3+) T regulatory (Treg) cells that suppress T cell proliferation but do not secrete IL-2, and CD25- uncommitted primed precursor Th (Thpp) cells that secrete IL-2 but do not suppress in standard Treg suppressor assays.
6378 17082610 Distinct molecular program imposed on CD4+ T cell targets by CD4+CD25+ regulatory T cells.
6379 17082610 CD4+CD25+ regulatory T cells (Tregs) are key modulators of immunity, but their mechanism of action is unclear.
6380 17082610 To elucidate the molecular consequences of Treg encounter, we analyzed changes in gene expression in CD4+ T cell targets activated in the presence or absence of CD4+CD25+ Tregs.
6381 17082610 Therefore, we compared the gene profile of T cells following Treg encounter with that of T cells made anergic, TGF-beta-treated, or IL-2-deprived; all possible modes of Treg action.
6382 17082909 DHEAS was not effective in modulating antigen-specific T-cell proliferation, Interleukin-2 production or percentage of recent activated T-cell subsets (CD4 + CD69 + and CD8 + CD69 +).
6383 17087061 The parameters of specific humoral (IgG and IgM) and cellular (gamma-interferon (IFN) and cell proliferation) immunities and the activity of cytokines (necrosis tumor factor-alpha, interleukin (IL)-1beta, IL-2, IL-6, IL-10, and IL-12) were studied.
6384 17087061 Noteworthy is the difference in the time course of changes in the levels of IL-6, IL-2, IL-12, and gamma-IFN in the immunized and non-immunized animals.
6385 17087061 The parameters of specific humoral (IgG and IgM) and cellular (gamma-interferon (IFN) and cell proliferation) immunities and the activity of cytokines (necrosis tumor factor-alpha, interleukin (IL)-1beta, IL-2, IL-6, IL-10, and IL-12) were studied.
6386 17087061 Noteworthy is the difference in the time course of changes in the levels of IL-6, IL-2, IL-12, and gamma-IFN in the immunized and non-immunized animals.
6387 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.
6388 17109338 IL-2 plus vaccine boosted CD4(+) T cell counts (P<.001) but did not diminish viral rebound.
6389 17113200 In DNA prime/poxvirus boost protocols, the strongest immune response, as measured by fresh IFN-gamma and IL-2 ELISPOT, was obtained in BALB/c mice boosted with NYVAC-B, while in HHD mice there were no differences between the poxvirus vectors.
6390 17114495 Hepatitis B surface Ag (HBs)-specific memory CD4+T cells were heterogeneous and included T(CM) (CCR7+CD27+) and T(EM) (CCR7(-)CD27(+/-)).
6391 17114495 HBs-specific T(CM) and T(EM) shared the capacity to produce multiple cytokines, including IL-2 and IFN-gamma.
6392 17114495 Several years postimmunization, approximately 10% of HBs-specific memory CD4+ T cells were in cycle (Ki67+) and the proliferating cells were CCR7+.
6393 17114751 Protection in these five groups was associated with the induction of cell-mediated or T helper 1 (Th1) type of immune responses characterized by the production of large amounts of interferon-gamma and interleukin-2 in in vitro proliferation assays using E. ruminantium antigens for stimulation.
6394 17114751 Further evaluation of these and other untested DNA constructs is necessary to optimize their expression in vivo in the presence of molecular adjuvants, such as the IFN-gamma gene, GM-CSF gene, IL-12 gene, and CpG motifs to fully evaluate their protective value.
6395 17142726 Functional adaptive CD4 Foxp3 T cells develop in MHC class II-deficient mice.
6396 17142726 CD4 Foxp3 regulatory T (T(R)) cells are well-defined regulator T cells known to develop in the thymus through positive selection by medium-to-high affinity TCR-MHC interactions.
6397 17142726 CD4 Foxp3 T(R) cells are found in secondary lymphoid tissues (spleen and lymph nodes) and peripheral tissues (liver) but not the thymus of severely MHC class II-deficient (Aalpha(-/-) B6) mice.
6398 17142726 Furthermore, these T(R) cells suppress IL-2 release and proliferative responses in vitro of naive CD25(-) (CD4 or CD8) T cells from normal B6 mice primed by bead-coupled anti-CD3/anti-CD28 Ab as efficiently as CD4CD25(high) T(R) cells from congenic, normal B6 mice.
6399 17142726 MHC class II-independent CD4 Foxp3(+) T(R) cells thus preferentially express the (TGF-beta-induced) integrin molecule alpha(E) (CD103), are generated mainly in the periphery and efficiently mediate immunosuppressive effects.
6400 17142738 Dendritic cell targeting of survivin protein in a xenogeneic form elicits strong CD4+ T cell immunity to mouse survivin.
6401 17142738 To determine whether strong CD4+ T cell immunity could be induced to a nonmutated self protein that is important for tumorigenesis, we selectively targeted the xenogeneic form of survivin, a survival protein overexpressed in tumors, to maturing dendritic cells in lymphoid tissues.
6402 17142738 Dendritic cell targeting via the DEC205 receptor in the presence of anti-CD40 and poly(I:C) as maturation stimuli, induced strong human and mouse survivin-specific CD4+ T cell responses, as determined by IFN-gamma, TNF-alpha, and IL-2 production, as well as the development of lytic MHC class II-restricted T cells and memory.
6403 17142738 Immunity was enhanced further by depletion of CD25+foxp3+ cells before vaccination. anti-DEC205-human survivin was superior in inducing CD4+ T cell responses relative to other approaches involving survivin plasmid DNA or survivin peptides with adjuvants.
6404 17142738 However, we were unable to induce CD8+ T cell immunity to survivin by two doses of DEC205-targeted survivin or the other strategies.
6405 17142738 Therefore, significant CD4+ T cell immunity to a self protein that is overexpressed in most human cancers can be induced by DEC205 targeting of the Ag in its xenogeneic form to maturing DCs.
6406 17142789 Synergism between CpG-containing oligodeoxynucleotides and IL-2 causes dramatic enhancement of vaccine-elicited CD8+ T cell responses.
6407 17142789 When we administered therapeutic vaccines containing the MHC class I-presented self-peptide tyrosinase-related protein (TRP)-2(180-188) and CpG-containing oligodeoxynucleotides (CpG ODN) to mice, growth of the TRP-2-expressing B16F1 melanoma was not inhibited compared with growth in mice that received control vaccinations.
6408 17142789 When we added systemic IL-2 to the TRP-2(180-188) plus CpG ODN vaccines, growth of B16F1 was inhibited in a CD8-dependent, epitope-specific manner.
6409 17142789 The antitumor efficacy of the different regimens correlated with their ability to elicit TRP-2(180-188)-specific CD8+ T cell responses.
6410 17142789 When we administered TRP-2(180-188) plus CpG ODN-containing vaccines with systemic IL-2, 18.2% of CD8+ T cells were specific for TRP-2(180-188).
6411 17142789 Identical TRP-2(180-188) plus CpG ODN vaccines given without IL-2 elicited a TRP-2(180-188)-specific CD8+ T cell response of only 1.1% of CD8+ T cells.
6412 17142789 Vaccines containing TRP-2(180-188) without CpG ODN elicited TRP-2(180-188)-specific responses of 2.8% of CD8+ T cells when administered with IL-2.
6413 17142789 There was up to a 221-fold increase in the absolute number of TRP-2(180-188)-specific CD8+ T cells when IL-2 was added to TRP-2(180-188) plus CpG ODN-containing vaccines.

6539 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.
6540 17223970 The production of IFN-gamma and IL-2 of the three groups together correlated directly with the serum anti-Tg activity.

6544 17223970 Initially, TNF-alpha and IL-2 were produced in all three groups, accompanied by IL-10.

6569 17230439 Although phosphoantigen activated immediately a strong release of systemic Th1 cytokines (IL-2, IL-6, IFN-gamma, TNF-alpha), it further anergized blood gammadelta T lymphocytes selectively.
6570 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.
6571 17283172 Two delivery systems, cDNA delivered by gene gun and Venezuelan equine encephalitis virus-like replicon particles (VRP), both encoding mouse STEAP (mSTEAP) and three vaccination strategies were used.
6572 17283172 Our results show that mSTEAP-based vaccination was able to induce a specific CD8 T-cell response against a newly defined mSTEAP epitope that prolonged the overall survival rate in tumor-challenged mice very significantly.
6573 17283172 Surprisingly, CD4 T cells that produced IFNgamma, tumor necrosis factor-alpha (TNF-alpha), and interleukin-2 (IL-2) played the main role in tumor rejection in our model as shown by using CD4- and CD8-deficient mice.
6574 17312111 Splenocyte cultures from the mice coadministrated with WNV E DIII protein and CpG secreted large amounts of IFN-gamma and IL-2 and showed proliferation of T cells in the presence of WNV E DIII protein.
6575 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.
6576 17335944 Our studies show that DS protects mice against disseminated candidiasis by the CD4+ Th1 immune response.
6577 17346863 The immunization induced F. tularensis-specific antibody responses in the serum and bronchoalveolar lavage fluids, as well as antigen-specific splenocyte proliferation and IFN-gamma and IL-2 production.
6578 17372991 For CD8(+ )T cells, successful generation of memory cells has been linked to IL-7 receptor alpha (IL-7Ralpha) expression, suggesting a role for IL-7 signaling, which in turn is important for preventing T cell apoptosis.
6579 17372991 We thus investigated the kinetics and changes of IL-7Ralpha and anti-apoptotic protein Bcl-2 expression levels in tetanus toxoid (TT)-specific CD4(+ )T cells at different time points prior and after TT re-immunization of TT-immune individuals.
6580 17372991 Prior to re-immunization, most TT-specific CD4(+ )T cells were high IL-2 producers, CD45RA(-)CCR7(+), IL-7Ralpha(high)Bcl-2(high) cells, resembling typical long-lived central memory cells.
6581 17372991 Already 5 days, and more importantly at the peak of the response, after TT re-immunization, a substantial fraction of these cells secreted also IFN-gamma, down-regulated CCR7, IL-7Ralpha and Bcl-2 and became Ki67 positive, resembling effector memory cells.
6582 17372991 Interestingly, a significant fraction of IL-7Ralpha(high)Bcl-2(high) TT-specific CD4(+ )T cells, i.e. the proposed memory cell precursors, remained stable at any time point upon re-immunization.
6583 17397028 Compared with the native peptide, the agonist (i) bound to HLA-A2 molecules at lower peptide concentrations, (ii) demonstrated a higher stability of the peptide HLA-A2 complex, (iii) induced higher levels of production of IFN-gamma, Granzyme B, TNF-alpha, IL-2 and lymphotactin by PAGE4-specific T-cell lines and (iv) T-cell lines generated against the agonist peptide were more efficient to lyse HLA-A2 human tumor cells expressing native PAGE4.
6584 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.
6585 17408744 Similarly three- to fivefold more amounts of IL-2 and IFN-gamma were secreted by immune splenocytes in response to in vitro re-stimulation with peptidomimics.
6586 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.
6587 17412629 Depletion experiments showed that immunoprotection required the cooperative action of CD4(+) and CD8(+) T cells in association with IFN-gamma and IL-12.
6588 17418457 Although high ratios of specific IgG2a/IgG1 were measured against both proteins, only spleen cells from GRA2-immunized mice and mix-immunized mice produced high amounts of both IFN-gamma and IL-2 upon induction with Toxoplasma gondii Excretory-Secretory Antigens.
6589 17429840 Here we show that this response is dependent upon antigen-responsive CD4 T cells, at least across transwell membranes; this requirement cannot be replaced by IL-2.
6590 17429840 Primed WC1(+) gammadelta T cells circulated as CD62L(hi)/CD45RO(int)/CD44(lo), characteristics of T(CM) cells.
6591 17429840 When stimulated with antigen, they decreased CD62L, increased CD44 and CD25, and had no change in CD45RO expression.
6592 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.
6593 17440051 SIV-specific CD8+ T cells express high levels of PD1 and cytokines but have impaired proliferative capacity in acute and chronic SIVmac251 infection.
6594 17440051 Programmed death-1 (PD-1) is a critical mediator of virus-specific CD8+ T-cell exhaustion.
6595 17440051 Here, we examined the expression of PD-1 on simian immunodeficiency virus (SIV)-specific CD8+ T cells and its possible involvement in regulation of cytokine production, proliferation, and survival of these cells.
6596 17440051 The majority of SIV-specific CD8+ T cells expressed a PD-1(high) phenotype, independent of their differentiation status, in all tissues tested.
6597 17440051 PD-1 expression gradually declined on CD8+ T cells specific for SIV-derived epitopes that had undergone mutational escape, indicating that antigen-specific TCR stimulation is the primary determinant of PD-1 expression.
6598 17440051 SIV-specific PD-1(high)CD8+ T cells produced IFN-gamma, TNF-alpha, and IL-2 under cognate peptide stimulation.
6599 17440051 While CD8+ T cells that proliferated in response to antigen had a PD-1(high) phenotype, it was determined that there was a reduced proliferative capacity of PD-1(high) compared with PD-1(low) SIV-specific CD8+ T cells.
6600 17440051 PD-1(high) SIV-specific CD8+ T cells were highly susceptible to cell death leading to loss of such cells after in vitro stimulation.
6601 17440051 Thus, PD-1 is a negative regulator of SIV-specific CD8+ T cells, operating predominantly through the induction of cell death.
6602 17440051 Manipulation of the interaction of PD-1 with its ligands could thus potentially restore the CD8+ T-cell responses in SIV infection.
6603 17446015 The immune stimulating activity was studied by measuring serum anti-HBsAg titer and cytokines level (IL-2 and IFN-gamma) following topical applications of plasmid DNA loaded cationic transfersomes in Balb/c mice and results were compared with naked DNA applied topically as well as naked DNA and pure recombinant HBsAg administered intramuscularly.
6604 17447028 The results showed that HIV-1 specific antibody in serum and increased T lymphocyte subsets (CD4(+) T, CD8(+) T) were detected in the immunization group.
6605 17447028 CTL target-killing activity and higher secretion of Th1 cytokines (IFN-gamma and IL-2) of spleen lymphocytes stimulated by H-2(d)-restricted CTL peptide were observed in immunized mice.
6606 17451293 Thus, Th l type cells produce IL-2 and IFN y, whereas Th 2 cells produce IL-4 and IL-5.
6607 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.
6608 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.
6609 17485666 After immunizations, all animals developed an HCV-specific immune response including IFN-gamma(+), IL-2(+), CD4(+), and CD8(+) T cell and proliferative lymphocyte responses against core, E1, and E2.
6610 17514769 Allogeneic retrovirally transduced, IL-2- and IFN-gamma-secreting cancer cell vaccine in patients with hormone refractory prostate cancer--a phase I clinical trial.
6611 17523874 In the first set of experiments, PBMCs were stimulated in vitro with tinctures alone and assayed for proliferation and production of interleukin-10 (IL-10), IL-12, and tumor necrosis factor-alpha (TNF-alpha).
6612 17523874 PBMCs from vaccinated individuals were stimulated in vitro with Echinacea tinctures and influenza virus; cytokine production (IL-2, IL-10, and interferon-gamma [IFN-gamma]) was compared prevaccination and postvaccination.
6613 17523874 In the first experiments, (1) tinctures from E. angustifolia, E. pallida, E. paradoxa, and E. tennesseensis stimulated proliferation and tended to increase IL-10, (2) E. sanguinea and E. simulata stimulated only proliferation, (3) E. purpurea stimulated only IL-10, and (4) none of the extracts influenced IL-12 or TNF-alpha.
6614 17523874 In the second experiments, (1) tinctures from E. pallida, E. paradoxa, E. sanguinea, and E. simulata diminished influenza-specific IL-2, and (2) none of the extracts influenced influenza-specific IL-10 or IFN-gamma.
6615 17523874 In the first set of experiments, PBMCs were stimulated in vitro with tinctures alone and assayed for proliferation and production of interleukin-10 (IL-10), IL-12, and tumor necrosis factor-alpha (TNF-alpha).
6616 17523874 PBMCs from vaccinated individuals were stimulated in vitro with Echinacea tinctures and influenza virus; cytokine production (IL-2, IL-10, and interferon-gamma [IFN-gamma]) was compared prevaccination and postvaccination.
6617 17523874 In the first experiments, (1) tinctures from E. angustifolia, E. pallida, E. paradoxa, and E. tennesseensis stimulated proliferation and tended to increase IL-10, (2) E. sanguinea and E. simulata stimulated only proliferation, (3) E. purpurea stimulated only IL-10, and (4) none of the extracts influenced IL-12 or TNF-alpha.
6618 17523874 In the second experiments, (1) tinctures from E. pallida, E. paradoxa, E. sanguinea, and E. simulata diminished influenza-specific IL-2, and (2) none of the extracts influenced influenza-specific IL-10 or IFN-gamma.
6619 17535971 Vaccinia virus-specific CD8(+) T cells induced by both MVA and Dryvax were highly polyfunctional; they degranulated and produced interferon gamma, interleukin 2, macrophage inflammatory protein 1beta, and tumor necrosis factor alpha after antigenic stimulation.
6620 17535971 Responding CD8(+) T cells exhibited an unusual phenotype (CD45RO(-)CD27(intermediate)).
6621 17549472 In the group with only one invaded lymph node, the estimated relapse rate was significantly lower (P (adjusted) = 0.0219) and the overall survival was increased (P (adjusted) = 0.0125) in the TIL+IL-2 arm compared with the IL-2 only arm.
6622 17553885 Virus-specific CD4 T cells are endowed with multiple functions, such as cytokine production, CD40 ligand (CD40L) expression (associated with the costimulation of CD8 and B cells), and degranulation (associated with cytotoxic potential).
6623 17553885 CD4 T cells specific for each of the viruses produced all seven possible combinations of the cytokines gamma interferon (IFN-gamma), interleukin-2, and tumor necrosis factor alpha.
6624 17558415 Here, using multiparameter flow cytometry to assess the immune responses after immunization, we show that the degree of protection against Leishmania major infection in mice is predicted by the frequency of CD4+ T cells simultaneously producing interferon-gamma, interleukin-2 and tumor necrosis factor.
6625 17561317 In vitro restimulation of lymphocytes from the Protollin-eRSV immunized mice with F (MHC-I) and G (MHC-II) peptides elicited F peptide-specific CD8(+) T cells and supernatant IFNgamma, TNFalpha, IL-2 and IL-10 while the formalin-inactivated RSV (FI-RSV) vaccine elicited predominantly IL-5.
6626 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.
6627 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.
6628 17563737 Production of Th2 cytokines IL-5 and IL-13 was superior to production of Th1 cytokines IFN-gamma and TNF-alpha.
6629 17570535 Here we report on the construction of a fusion protein consisting of a tuberculosis vaccine candidate mycolyl-transferase antigen 85A (Ag85A, Rv3804c) coupled to the outer membrane lipoprotein I (OprI) from Pseudomonas (P.) aeruginosa, a documented TLR2/TLR4 trigger.
6630 17570535 Intranasal priming of C57BL/6 mice with live, attenuated Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccine, followed by intranasal boosting with OprI-Ag85A increased systemic and local antigen-specific interferon (IFN)-gamma and interleukin (IL)-2 responses in spleen, draining cervical and mediastinal lymph nodes and particularly in lung tissue, as compared to responses in mice only vaccinated with BCG vaccine.
6631 17579032 During the primary immune response, we show generation of CD8+ memory T cell precursors expressing lymphoid homing molecules (CCR7, L-selectin) and homeostatic cytokine receptors (IL-7alpha, IL-2/IL-15beta).
6632 17579032 During long-term persistent infection, central-memory cells constitute 20-50% of the virus-specific CD8+ T cell population and maintain the expression of L-selectin, CCR7, and IL-7R molecules.
6633 17579032 Functional analyses demonstrate that during viral persistence: 1) CD8+ T cells maintain TCR affinity for peptide/MHC complexes, 2) the functional avidity of CD8+ T cells measured as the capacity to produce IFN-gamma is preserved intact, and 3) virus-specific CD8+ T cells have in vivo killing capacity.
6634 17579577 In the prime/boost-immunized animals, a significant proportion of CD8(+) T cells were stained positive for both interferon-gamma (IFN-gamma) and interleukin-2 (IL-2), a feature that has been associated with control of HIV-1 infection in long-term non-progressors.
6635 17584532 Neither granulocyte-macrophage colony-stimulating factor (GM-CSF) nor an immunogenic MHC class II-presented "helper" peptide increased the size of epitope-specific CD8+ T cell responses elicited by peptide+CpG-containing vaccines.
6636 17584532 In contrast, low-dose subcutaneous interleukin (IL)-2 dramatically increased the size of splenic and peripheral blood epitope-specific CD8(+) T cell responses generated by peptide+CpG-containing vaccines.
6637 17586093 Bejon and colleagues propose that levels of rapidly induced (effector memory) interleukin-2 and interferon gamma producing T-cells after vaccination with leading pre-erythrocytic stage vaccines predict the induction of resting memory responses (central memory).
6638 17589294 Cytoplasmic interferon-gamma production by freshly thawed peripheral blood mononuclear cells (direct ex vivo analysis) or by peripheral blood mononuclear cells subjected to 1 cycle of in vitro sensitization with peptide, interleukin-2, and interleukin-15 was measured following restimulation with the modified and native gp100 peptides, and also A2gp100 melanoma cell lines.
6639 17595664 Immunotherapy for neuroblastoma using syngeneic fibroblasts transfected with IL-2 and IL-12.
6640 17595664 Here we have compared the antitumour effect of fibroblasts and tumour cells transfected ex vivo to coexpress interleukin-2 (IL-2) and IL-12 in a syngeneic mouse model of neuroblastoma.
6641 17595664 We conclude that syngeneic fibroblasts cotransfected with IL-2 and IL-12 mediate therapeutic effects against established disease, and are capable of generating immunological memory.

6647 17595664 We conclude that syngeneic fibroblasts cotransfected with IL-2 and IL-12 mediate therapeutic effects against established disease, and are capable of generating immunological memory.
6648 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.
6649 17604883 In this study, we designed and characterized a mutant form of Tat ("STLA Tat"), which is unable to transactivate viral transcription, and which has lost the deleterious effects on the expression of MHC I, IL-2, and CD25 genes compared with wild-type Tat, as observed in lymphoid Jurkat cells that stably express the tat genes.
6650 17606603 Analysis of the cellular immune responses of immunized, uninfected mice demonstrated that the vaccine induced a significant increase in CD4(+) T cells producing gamma interferon, interleukin 2, and tumor necrosis factor cytokines, indicating a Th1-type immune response.
6651 17608690 This phenomenon was not related to the ability of both DC to induce CD25 expression on T cells, to lower secretion of interleukin-2, or to raise production of interleukin-10 during T-cell/16(-) mDC cocultures.
6652 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.
6653 17675478 Lipopeptide recalled D(b)PA(224)-specific CTL produced lower levels of IFN-gamma and TNF-alpha, but produced similar levels of IL-2 when compared with D(b)PA(224)-specific CTL recalled after virus infection.
6654 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.
6655 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.
6656 17682721 [CD8+ and CD4+ T lymphocyte responses against malaria].
6657 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.
6658 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.
6659 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.
6660 17682721 In this review article, CD8+ T and CD4+ T cell responses to malaria infection have been discussed in the light of current literature.
6661 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.
6662 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.
6663 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.
6664 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.
6665 17709416 Elevated numbers of granulocytes, CD8+ cells, and TCR1+ cells and mRNA expression rates for interleukin 12 (IL-12), IL-18, tumor necrosis factor alpha factor, and iNOS in cecum correlated well with the invasiveness of serovars in the lamina propria.
6666 17709416 In contrast, changes in numbers of TCR2+ and CD4+ cells and IL-2 mRNA expression seemed to be more dependent on infection of epithelial cells.
6667 17709486 Novel exosome-targeted CD4+ T cell vaccine counteracting CD4+25+ regulatory T cell-mediated immune suppression and stimulating efficient central memory CD8+ CTL responses.
6668 17709486 These EXO(OVA)-uptaken (targeted) CD4+ aT cells can stimulate CD8+ T cell proliferation and differentiation into central memory CD8+ CTLs and induce more efficient in vivo antitumor immunity and long-term CD8+ T cell memory responses than OVA-pulsed dendritic cells.
6669 17709486 They can also counteract CD4+25+ regulatory T cell-mediated suppression of in vitro CD8+ T cell proliferation and in vivo CD8+ CTL responses and antitumor immunity.
6670 17709486 We further elucidate that the EXO(OVA)-uptaken (targeted)CD4+ aT cell's stimulatory effect is mediated via its IL-2 secretion and acquired exosomal CD80 costimulation and is specifically delivered to CD8+ T cells in vivo via acquired exosomal peptide/MHC class I complexes.
6671 17709504 Although CD4+ T cell-directed dendritic cell vaccination primed effector-like (CD44(high)CD62L(low), IL-2(+), IFN-gamma(+)) and central memory-like lymphocytes (CD44(high)CD62L(high), only IL-2(+)) in tumor-free mice, this was not the case in tumor-bearing animals in which both priming and persistence of CD4+ T cell memory were suppressed.
6672 17728221 Here, we evaluate the cytokine coexpression profiles of human immunodeficiency virus (HIV)-specific CD4 T cells for the expression of the cytokines gamma interferon (IFN-gamma), interleukin-2, and tumor necrosis factor alpha.
6673 17765942 Antigen stimulation of the CD4(+) T cells elicited production of high amounts of CCR5 chemokines MIP-1alpha (CCL3), MIP-1beta (CCL4), and RANTES (CCL5).
6674 17765942 Production of these CCR5 ligands was more readily and reproducibly detected than that of IFN-gamma or IL-2.
6675 17765942 Conversely, in the absence of antigen stimulation, the cells were readily infected by the virus, and after infection, their capacity to produce MIP-1beta and IFN-gamma rapidly declined.
6676 17823271 HIV-1-specific helper-T-cell activity was studied by measuring the levels of interleukin 2 (IL-2) produced by peripheral blood mononuclear cells (PBMCs) and the granule-dependent CTL activity by measuring the intracellular levels of perforin and granzyme B expression in CD8+ T cells after stimulation with gag p24 antigen.
6677 17823271 The levels of perforin and granzyme B expression in CD8+ T cells were also higher among EU individuals than among healthy controls.
6678 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.
6679 17868957 Furthermore, the levels of IL-2, IL-4 and IL-6 increased remarkably in the sera of immunized mice (P<0.05).
6680 17868958 Antigen-specific CD4(+) and CD8(+) T-cell responses to amplicon and adenovirus (rAd5) vectors encoding HIV-1 gp120 were assessed following immunization of mice, by performing intracellular cytokine staining for IFNgamma, IL2 and TNFalpha, following stimulation of splenocytes with a HIV-1 Env peptide pool.
6681 17881444 In contrast, the functional profiles of both CD8+ and CD4+ T cells, assessed by measuring antigen-stimulated gamma interferon and interleukin-2 production, were not predominantly shaped by the boosting immunogen.
6682 17881444 Expression of the memory-associated molecule CD27 on effector CD8+ T cells decreased following heterologous but not homologous boosting, resulting in a phenotypic profile similar to that seen on primary CD8+ T cells.
6683 17881504 In this study, we determined if the sensitivity of the currently available in vitro test to detect bovine tuberculosis could be enhanced by adding the following immunomodulators: interleukin-2 (IL-2); granulocyte-macrophage colony-stimulating factor (GM-CSF); antibodies neutralizing IL-10 and transforming growth factor beta (TGF-beta); mono-methyl-l-arginine, which blocks nitric oxide production; and l-methyl-tryptophan, which interferes with the indoleamine dioxygenase pathway.
6684 17881504 Mono-methyl-l-arginine, l-methyl-tryptophan, or an antibody neutralizing TGF-beta had minimal impact on IFN-gamma production.
6685 17881504 IL-2 and GM-CSF promoted IFN-gamma release whether antigen was present or not.

6725 17912460 When compared to monotherapy, the anti-neoplastic efficacy was significantly enhanced when intratumoral Ad.VSV-G administration was combined with adenovirus vectors encoding IL-2, IL-12, IL-18, IL-21, or GM-CSF.
6726 17916464 These include: (a) pathways to activate professional antigen presenting cells, such as through Toll-like receptors, growth factors, such as GM-CSF, and the CD40 pathway; (b) use of cytokines, such as IL-2, IL-12, and Interferon alpha to enhance immune activation; and (c) pathways that inhibit T cell inhibitory signals, or Tregs.
6727 17925026 In high responder monkeys, CD4+IL-2+ responses were more predominant than CD8+ T cell responses.
6728 17925026 Furthermore, CD8+ IFN-gamma responses were detected only in the presence of detectable CD4+ T cell responses.

6747 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.
6748 18020597 Clinical studies of the administration of exogenous IL-2 to HIV-infected patients have demonstrated that it can be given in well tolerated doses and that it can increase and sustain the number of CD4+ cells while only transiently affecting viral proliferation, especially when given to patients with CD4+ counts >200 cells/mm(3).

6786 18273057 We have previously shown that co-administration of DNA vaccines containing E6 or E7 protein of human papillomavirus 16 (HPV-16) combined with DNA encoding invariant (Ii) chain in which class II-associated Ii peptide (CLIP) region is replaced with the CD4(+) T helper epitope, PADRE (Pan-DR-epitope) (Ii-PADRE DNA) enhanced HPV antigen-specific CD8(+) T-cell immune responses in vaccinated mice.
6787 18273057 In the current study, we investigated the enhancement of HPV E7-specific CD8(+) T-cell immune responses by PADRE-specific CD4(+) T cells.

6789 18273057 Thus, our data suggest that activated PADRE-specific CD4(+) T helper cells may be required at the vicinity of E7-specific CD8(+) T cells where they secrete IL-2, which enhances the E7-specific CD8(+) T-cell immune responses generated by DNA vaccination.

6795 18273057 Thus, our data suggest that activated PADRE-specific CD4(+) T helper cells may be required at the vicinity of E7-specific CD8(+) T cells where they secrete IL-2, which enhances the E7-specific CD8(+) T-cell immune responses generated by DNA vaccination.
6796 18273057 Role of IL-2 secreted by PADRE-specific CD4+ T cells in enhancing E7-specific CD8+ T-cell immune responses.
6797 18273057 CD4(+) T helper cells are known to play an integral role in the generation of CD8(+) T-cell immune responses.
6798 18273057 We have previously shown that co-administration of DNA vaccines containing E6 or E7 protein of human papillomavirus 16 (HPV-16) combined with DNA encoding invariant (Ii) chain in which class II-associated Ii peptide (CLIP) region is replaced with the CD4(+) T helper epitope, PADRE (Pan-DR-epitope) (Ii-PADRE DNA) enhanced HPV antigen-specific CD8(+) T-cell immune responses in vaccinated mice.
6799 18273057 In the current study, we investigated the enhancement of HPV E7-specific CD8(+) T-cell immune responses by PADRE-specific CD4(+) T cells.

6801 18273057 Thus, our data suggest that activated PADRE-specific CD4(+) T helper cells may be required at the vicinity of E7-specific CD8(+) T cells where they secrete IL-2, which enhances the E7-specific CD8(+) T-cell immune responses generated by DNA vaccination.
6802 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.
6803 18280621 In an attempt to increase cross-presentation through apoptosis, the DNA-encoding caspase-2 prodomain followed by wild-type or catalytically inactive mutated caspase-3 was inserted into a plasmid encoding the 32 kDa mycolyl transferase (Ag85A) from Mycobacterium tuberculosis.
6804 18280621 Vaccination with pro-apoptotic plasmids triggered more Ag85A specific IFN-gamma producing spleen cells, and more efficient IL-2 and IFN-gamma producing memory cells in spleen and lungs after M. tuberculosis challenge.
6805 18280621 Compared to DNA-encoding secreted Ag85A, vaccination with DNA co-expressing wild-type caspase increased protection after infection with M. tuberculosis, while vaccination with plasmid co-expressing mutated caspase was not protective, possibly due to the stimulation of IL-6, IL-10 and IL-17A production.
6806 18286194 In addition, we found a higher frequency of triple-positive IFN-gamma, TNF-alpha and IL-2 secreting E3-specific CD8+ T-cells 8 weeks after vaccination with MVA lacking B15R.
6807 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.

6809 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.
6810 18292584 Importantly, many mycobacteria-specific CD4+ and CD8+ T cells did not produce IFN-gamma.

6822 18299268 Interleukin-21 (IL-21) is a newly described, typical, four-helix cytokine showing significant homology with IL-2, IL-4 and IL-15.
6823 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).
6824 18299268 Plasma IL-21 levels correlated with IgG1 and IgG3 levels.
6825 18299268 Additionally, plasma IL-21 levels correlated with hemoglobin levels in younger children and with parasite density.
6826 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.
6827 18316415 However, only the memory precursors were capable of making interleukin (IL) 2, thus defining a novel effector cell that was cytotoxic, expressed granzyme B, and produced inflammatory cytokines in addition to IL-2.
6828 18319583 The results revealed that IFN-gamma and IL-6 were upregulated during the first week post-vaccination.
6829 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.
6830 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.
6831 18337575 While rAd5-Gag induced primarily gamma interferon-positive (IFN-gamma(+)) and IFN-gamma(+)/tumor necrosis factor alpha(+) (TNF-alpha(+)) T-lymphocyte responses, rAd26-Gag and rAd48-Gag induced higher proportions of interleukin-2(+) (IL-2(+)) and polyfunctional IFN-gamma(+)/TNF-alpha(+)/IL-2(+) T-lymphocyte responses.
6832 18337575 These data demonstrate that the rare serotype rAd vectors elicited T-lymphocyte responses that were phenotypically distinct from those elicited by rAd5 vectors and suggest the functional relevance of polyfunctional CD8(+) and CD4(+) T-lymphocyte responses.

6879 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).
6880 18354238 IL-2/anti-IL-2 antibody complex enhances vaccine-mediated antigen-specific CD8+ T cell responses and increases the ratio of effector/memory CD8+ T cells to regulatory T cells.
6881 18354238 IL-2 is well described as a cytokine with two markedly distinct functionalities: as a necessary signal during CD4(+) and CD8(+) T cell activation/expansion and as an essential cytokine for the maintenance of CD4(+)CD25(+)FoxP3(+) T cells (regulatory T (T(REG)) cells) during homeostasis.
6882 18354238 IL-2 complex led to an increase in the number of Ag-specific effector/memory CD8(+) T cells, cytokine production, and CTL lysis following Ag-specific restimulation in a vaccination setting.
6883 18354238 Moreover, in contrast to the use of IL-2 alone, IL-2 complex greatly increased the ratio of effector/memory CD8(+) T cells to T(REG) cells.

6896 18360705 Here, we demonstrated the strong potentiation of the T cell stimulatory activity of such a vaccine upon attachment of bispecific or trispecific fusion proteins which bind with one arm to viral HN molecules of the vaccine, and with the other arm either to CD3 (signal 1), to CD28 (costimulatory signal 2a), or to interleukin-2 receptor (costimulatory signal 2b) on T cells.
6897 18370224 Plasmid DNA encoding the HBV preS2-S and an adjuvant plasmid encoding a fused gene of IL-2 and IFN-gamma were injected intramuscularly followed by electroporation once a month for several months.
6898 18382856 For example, interferon-alpha (IFNalpha) and interleukin (IL)-2 have been used to treat chronic hepatitis C virus infection and metastatic melanoma, respectively.
6899 18389062 Furthermore, M2 protein expression in primary murine B cells drives high level IL-10 expression along with increased secretion of IL-2, IL-6, and MIP-1alpha.
6900 18389062 M2 protein expression in primary B cells also led to upregulated surface expression of the high affinity IL-2 receptor (CD25) and the activation marker GL7, along with down-regulated surface expression of B220, MHC II, and sIgD.
6901 18389062 Furthermore, M2 protein expression in primary murine B cells drives high level IL-10 expression along with increased secretion of IL-2, IL-6, and MIP-1alpha.
6902 18389062 M2 protein expression in primary B cells also led to upregulated surface expression of the high affinity IL-2 receptor (CD25) and the activation marker GL7, along with down-regulated surface expression of B220, MHC II, and sIgD.
6903 18392619 Tetramer analysis showed that vaccine-induced T cells recognizing gp100 and tyrosinase are present at the vitiligo lesions.
6904 18392619 These T cells secrete IFN-gamma and IL-2 upon peptide specific stimulation as well as upon recognition of the autologous tumor.
6905 18400973 Against this background, we evaluated the immune response of infants to mycobacterial antigens over the 2 years following BCG vaccination at birth by measuring the gamma interferon (IFN-gamma), interleukin-2 (IL-2), and CD154 responses of CD4 T cells.
6906 18413771 In vitro, aAPC specifically primed Ag-specific CD4(+) T cells that were activated to express high levels of CD44, produced mainly interleukin 2, and could differentiate into Th1-like or Th2-like cells in combination with polarizing cytokines.
6907 18417356 Interestingly, IL-2 and IL-15 are also able to render CD4+ T cells permissive to HIV infection through their influence on the activity of the APOBEC3G deaminase enzyme.
6908 18417356 Herein, we describe the current state of knowledge on how the gammac cytokine network is affected during HIV infection, with a focus on how this impairs CD4+ and CD8+ T cell function while also benefiting the virus itself.
6909 18419256 The corresponding synthetic peptides (SP1 to SP3) were then tested for their abilities to induce proliferation of CD4 T cells isolated from five human volunteers screened positive for previous EV 71 exposure and one EV 71-negative volunteer.
6910 18419256 Moreover, CD4 T cells from EV 71-positive volunteers produced significant levels of IL-2 and IFN- upon stimulation, indicative of a T-cell differentiation into Th-1-type subset.
6911 18419256 Moreover, SP2-induced proliferative response could be inhibited with anti-major histocompatibility complex (MHC) class II antibody, indicating that SP2 represents a MHC class II-restricted CD4 T-cell epitope.
6912 18433946 Immunization with an HIV-1 immunogen induces CD4+ and CD8+ HIV-1-specific polyfunctional responses in patients with chronic HIV-1 infection receiving antiretroviral therapy.
6913 18433946 Fifty-four HIV-1 infected patients receiving antiretroviral treatment (ART) and immunization with an HIV-1 immunogen or placebo, periodically every 3 months throughout a period of 36 months, were evaluated for the purposes of analysing the development of HIV-1-specific CD4+ and CD8+ responses.
6914 18433946 A significant increase of proliferating and IFN-gamma producing CD8+ HIV-1-specific T cells, of HIV-1-specific precursor frequencies for CD8+ and for CD4+ T cells and of Gag/pol-specific memory CTL precursors (CTLp) was observed in the immunogen group in comparison to placebo.
6915 18433946 IL-2 intracellular expression and IFN-gamma and TNF-alpha co-expression in HIV-1-specific CD8+ T cells were also substantially increased in the immunized group.
6916 18449216 Membrane-anchored C-peptides (for example, maC46) derived from human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein gp41 effectively inhibit HIV-1 entry in cell lines and primary human CD4+ cells in vitro.
6917 18449216 Depletion of CD8+ T cells from PBMCs enhanced the yield of maC46-transduced CD4+ T cells.
6918 18449216 Supplementation with interleukin-2 (IL-2) increased transduction efficiency, whereas IL-7 and/or IL-15 provided no additional benefit.
6919 18449216 Phenotypic analysis showed that maC46-transduced and expanded cells were predominantly central memory CD4+ T cells that expressed low levels of CCR5 and slightly elevated levels of CD62L, beta7-integrin and CXCR4.
6920 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.
6921 18468739 In vitro restimulation with antigen-pulsed bone marrow-derived dendritic cells (BMDCs) induced remarkable T-cell proliferative response specific for both VP1 and EGFP antigen and IL-2 and IFN-gamma production.
6922 18468739 After intranasal administration of EGFP-VLPs, as well as after polyomavirus infection, a moderate reduction of CD4(+)CD25(+)Foxp3(+) T cells was observed in spleens but not in lymph nodes and peripheral blood, suggesting that both MPyV virions and pseudocapsids are able to induce changes in distribution of regulatory T cells.
6923 18479753 The expressions of CD80/CD86 on B cells, and CD154/CD25 on T cells, were analyzed by flow cytometry (FCM), and IL-2 production was assayed by ELISA.
6924 18479753 The hCGbeta-hC3d3 fusion protein enhanced the expression of CD80 and CD86 on B cells, especially CD86 (P<0.05), and significantly increased the expression of CD154 and CD25 molecules on T cells compared to that of hCGbeta (P<0.05).
6925 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.
6926 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).
6927 18483933 Antigen-specific lymphoproliferation and interleukin-2 (IL-2) and interferon-y (IFN) production were used to measure cross-reactive cell mediated immune responses.

6956 18505805 Cytokine quantitation for the sera of SchuS4-challenged mice indicated that OMP and iLVS immunizations induced high levels of tumor necrosis factor alpha and interleukin-2 (IL-2) production, whereas only OMP immunization induced high levels of IL-10 production.
6957 18505805 By comparison, high levels of proinflammatory cytokines, including RANTES, granulocyte colony-stimulating factor, IL-6, IL-1alpha, IL-12p40, and KC, in nonvaccinated mice indicated that these cytokines may facilitate disease progression.

6984 18566382 Coligation of the hepatitis C virus receptor CD81 with CD28 primes naive T lymphocytes to acquire type 2 effector function.
6985 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.
6986 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.
6987 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.
6988 18566382 The hepatitis C virus envelope protein E2 is the only ligand known for CD81.
6989 18572242 Nine cytokine genes (IL-2, -4, -10, -12, -13, -18, TNFalpha, TGFbeta and IFNgamma) and Cox-2 were selected for analysis.
6990 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.
6991 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.
6992 18579590 We assessed both the magnitude and the functional profile of the virus-specific CD8(+) T cells by measuring gamma interferon, interleukin-2, and tumor necrosis factor alpha production.

7000 18598175 The CA-elicited production of the Th1 cytokines tumor necrosis factor (TNF)-alpha, interleukin (IL)-2, and interferon (IFN)-gamma was increased after Immunlina administration for 3 days (P < .001, < .03, and < .007, respectively), and increased IL-2 production persisted after 56 days (P < .004).
7001 18598175 The TNF-alpha, IFN-gamma, and IL-6 responses to TT were enhanced after 8 and 14 days (P < .002-.05), while IL-5 responses increased significantly within 3 days (P < .04) and fell below baseline levels after 14 days (P < .008).
7002 18598175 Upon addition to normal mononuclear cells in vitro, Immulina elicited strong TNF-alpha, IL-1beta, and IL-6 responses, indicating that it acts by inducing a pro-inflammatory state.
7003 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).

7013 18636165 The effect of the treatment was not enhanced by the simultaneous administration of non-oncogenic, genetically modified TC-1 cells expressing either IL-2, IL-12 or GM-CSF, and, in fact, the oncolytic effect of the virus was even less expressed in some instances.
7014 18657205 Differential expression of CD26 on virus-specific CD8(+) T cells during active, latent and resolved infection.
7015 18657205 Immunophenotypic analyses using multi-parameter flow cytometry and tetramer technology identified a unique pattern of CD26(high) expression among influenza-specific CD8(+) T cells, but not among CD8(+) T cells specific for CMV, EBV (three different epitopes) or HIV.
7016 18657205 The median percentage of CD8(+) T cells expressing CD26 was 95.5% for influenza, but for cells specific for CMV, EBV and HIV it was 10.5%, 12%-19%, and 13.2%, respectively.
7017 18657205 CD26(high) expression correlates with expression of CD127, a marker of memory cells.
7018 18657205 Furthermore, CD26(high) cells can produce interleukin-2.
7019 18657205 These findings offer insight into the dynamics of T-cell differentiation, and they may offer a specific marker of a successfully developed memory CD8(+) T cell, that of CD26(high).
7020 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.
7021 18675872 To this purpose, the chimeric protein rEC2, encoding antigenic fragments of surface-associated proteins MIC2, MIC3 and SAG1, was combined with pGRA7 plasmid DNA or rGRA7 protein.
7022 18675872 The protein-DNA vaccine elicited a polarized Th1/Th2 immune response, characterized by IFN-gamma and IL-10, and afforded low protection (24%) against brain cyst formation.
7023 18675872 In contrast, the protein-protein vaccine elicited a Th1-focused immune response, characterized by IFN-gamma and IL-2 production, conferring a strong protection (79%) against brain cyst formation in chronic toxoplasmosis.
7024 18677602 In the Abeta(42) group, IL2 and IFN-gamma were relatively low and IL4 and IL10 were relatively high.

7028 18695871 Melanoma-associated antigens, MART-1, tyrosinase, gp100 and MAGEs, are typical melanoma-specific tumor antigens which can potently induce immune responses in metastatic melanoma patients treated with peptide vaccines.
7029 18695871 In the present study, we established a dendritic cell (DC)-based HLA-A2 melanoma-associated peptide (MART-1 or gp100)-specific CTL induction method and characterized the CTLs using HLA-A2 tetramer staining in 6 cases of HLA-A2+ melanoma treated with DC vaccines.
7030 18695871 Peripheral blood mononuclear cells (PBMC) from patients were stimulated twice with MART-1 A2 peptide-pulsed DCs in the presence of a low dose of IL-2.
7031 18695871 Finally, we were successful in identifying melanoma peptide-specific T-cell receptor (TCR) cDNAs in 2 cases for MART-1 and 1 case for gp100 using the anti-TCR MoAb-based sorting as a novel approach instead of a conventional cell cloning, and confirmed peptide-specific IFN-gamma production in TCR cDNA-transduced naïve T cells.

7033 18698349 In another physiologically relevant system, we show that the strength of peptide stimulation, high frequency of responder CD8+ T cells or presence of high IL-2 can override the suppression of HIV-specific CD8+ T cells by Tregs.
7034 18704362 Immunizing patients who have hormone-refractory prostate cancer with an allogenic IL-2 and IFN-gamma secreting tumor cell vaccine is safe and feasible with no dose-limiting toxicity; it has been shown to reduce the progression of prostate-specific antigen in treated subjects and to induce vaccine-specific immune responses.
7035 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.
7036 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.
7037 18716452 The levels of TNF-alpha and IFN-gamma induced by LVS were 5 times lower than those induced by the Pohang isolate.
7038 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.
7039 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.
7040 18753231 The response of five baboons to Gag peptides in a gamma interferon (IFN-gamma) enzyme-linked immunospot (ELISPOT) assay after three pTHGag immunizations ranged from 100 to 515 spot-forming units (s.f.u.) per 10(6) peripheral blood mononuclear cells (PBMCs), whilst the response of two baboons to the Gag VLP vaccine ranged from 415 to 465 s.f.u. per 10(6) PBMCs.
7041 18753231 Gag VLPs, given as a single-modality regimen, induced a predominantly CD8+ T-cell IFN-gamma response and interleukin-2 was a major cytokine within a mix of predominantly Th1 cytokines produced by a DNA-VLP prime-boost modality.
7042 18761033 Inhibition was not reversed by treatment with IL-2 and IL-6 treatment.
7043 18761418 All mice vaccinated with rPRV/SAG1 developed a high level of specific antibody responses against T. gondii lysate antigen (TLA), a strong increase of the splenocyte proliferative response, and significant levels of IFN-gamma and IL-2 production.
7044 18779742 Twenty-seven patients with progressive cytokine-refractory metastatic renal cell carcinoma were vaccinated with DCs loaded with either a cocktail of survivin and telomerase peptides or tumor lysate depending on their HLA-A2 haplotype, and low-dose IL-2 was administered concomitantly.
7045 18779742 Tumor response, immune response, and serum IL-6 and YKL-40 were measured during treatment.
7046 18779742 Furthermore, significant alterations in serum YKL-40 and IL-6 were found during treatment.
7047 18791162 The uncleaved 12-kDa form of p12(I) resides in the ER and interacts with the beta and gamma(c) chains of the interleukin-2 receptor (IL-2R), the heavy chain of the major histocompatibility complex (MHC) class I, as well as calreticulin and calnexin.
7048 18794906 The CC chemokine receptor 7 (CCR7) and cognate CCR7 ligands, CCL19 and CCL21, help establish microenvironments in lymphoid tissue that can facilitate encounters between naive T cells and mature dendritic cells (DCs).
7049 18794906 The co-injection of CCR7 ligand DNA consistently enhanced the level of Th1-type cytokines (IL-2 and IFN-gamma) produced by stimulated immune cells when compared with a group that was vaccinated with the PrV DNA vaccine.
7050 18794906 Moreover, the co-administration of CCR7 ligand DNA increased the number of mature DCs into the secondary lymphoid tissues, which appeared to enhance the proliferation of PrV-immune CD4(+) T cells.
7051 18802099 Mice boosted intradermally make very strong splenic CD4 and CD8 Th1 cytokine responses to Ag 85A, but show no change in lung mycobacterial burden over BCG primed animals.
7052 18802099 In contrast, intranasally boosted mice show greatly reduced mycobacterial burden and make a much weaker splenic response but a very strong lung CD4 and CD8 response to Ag 85A and an increased response to purified protein derivative.
7053 18802099 This effect is associated with the presence in the lung of multifunctional T cells, with high median fluorescence intensity and integrated median fluorescence intensity for IFN-gamma, IL-2, and TNF.

7064 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.
7065 18819411 Synthesis of several serum interleukins (IL-2, IL-10) did not changed 4 and 24 hours after inoculation irrespective from dose of PST.
7066 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).
7067 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.
7068 18832706 CD8(+) T cell responses were more frequent and of a greater magnitude than CD4(+) T cell responses (p < 0.001).
7069 18832706 Polychromatic cytometry analysis indicated that the virus-specific T cells from the severe group tended to be a central memory phenotype (CD27(+)/CD45RO(+)) with a significantly higher frequency of polyfunctional CD4(+) T cells producing IFN-gamma, TNF-alpha, and IL-2, and CD8(+) T cells producing IFN-gamma, TNF-alpha, and CD107a (degranulation), as compared with the mild-moderate group.
7070 18833003 Detection of intracellular cytokine production (interleukin-2, interferon-gamma, and tumor necrosis factor-alpha) upon phorbol 12-myristate 13-acetate-ionomycin stimulation in CD8alphaalpha+ and CD8alphabeta+ T-cells revealed that CD8alphaalpha+ T-cells show a unique cytokine production pattern (tumor necrosis factor-alpha and interferon-gamma production) as compared with CD8alphabeta+ T-cells.
7071 18849136 H22 hepatoma tumor vaccine modified by human interleukin-2 (hIL-2) and mouse granulocyte-monocyte colony-stimulating factor (mGM-CSF) fusion gene was prepared to study its specific anti-tumor immunity.
7072 18849136 The blood was needed to test the level of IL-10 and interferon (IFN)-gamma in serum.
7073 18849136 Serum IFN-gamma in the immunized group was significantly increased compared with other groups (p<0.01), and serum IL-10 in the immunized group was significantly decreased compared with other groups (p<0.01).
7074 18936481 Here we demonstrate that the combined use of two different types of immune adjuvants, one that directly targets the CD8 cell, IL-2/anti-IL-2 mAb complexes, and one that targets the innate immune system, poly(I:C), can achieve this goal.
7075 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.
7076 18974619 We have developed a novel tuberculosis (TB) vaccine ; a combination of the DNA vaccines expressing mycobacterial heat shock protein 65 (HSP65) and interleukin 12 (IL-12) delivered by the hemagglutinating virus of Japan (HVJ)-liposome or-envelope (HSP65+IL-12/HVJ).
7077 18974619 The Elispot assay showed that HSP65+IL-12 DNA/ HVJ vaccine induced a greater number of IFN-gamma producing T cells than BCG in the mouse model.
7078 18974619 This novel vaccine provided a higher level of the protective efficacy than BCG based upon the assessment of mortality, the ESR, body weight, chest X-ray findings and immune responses (IFN-gamma, IL-2, IL-6 production , and lymphocyte proliferation of cynomolgus monkey).
7079 18974619 The combination of HSP65+IL-12/HVJ and BCG by the priming-booster method showed a synergistic effect in the TB-infected cynomolgus monkey (100% survival).
7080 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.
7081 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.
7082 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.
7083 19006832 Direct correlation between IL-6 and IL-8 levels was observed during whole period post-immunization.

7087 19007952 Proliferation of mononuclear cells of the spleen, levels of gamma interferon, interleukin-12, and interleukin-2 mRNAs were enhanced in immunized animals.
7088 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.
7089 19009291 Also, anti-inflammatory effects on LPS-stimulated monocytes (TNF-alpha is decreased) and costimulatory effects on anti-CD3 stimulated T cells, (enhanced T cell proliferation and proinflammatory cytokine production) are observed.
7090 19009291 Both drugs inhibit IL-2-mediated generation of FOXP3 positive CTLA-4 positive CD25high CD4+ T regulatory cells from PBMCs by upto 50%.
7091 19009291 Inhibition of T regulatory cell function was not due to changes in TGF-beta or IL-10 production but was associated with decreased T regulatory cell FOXP3 expression.

7134 19017952 During T cell interaction with APC, CD28 is recruited to the central region (cSMAC) of the immunological synapse.
7135 19017952 CD28-mediated signaling through PI3K results in the recruitment of protein kinase C-theta (PKCtheta) to the cSMAC, activation of NF-kappaB, and up-regulation of IL-2 transcription.
7136 19017952 In this report, we show that CD28 recruitment and persistence at the immunological synapse requires TCR signals and CD80 engagement.
7137 19017952 Addition of mAb to either MHC class II or CD80 results in the rapid displacement of CD28 from the immunological synapse.
7138 19017952 Ligand binding is not sufficient for CD28 localization to the immunological synapse, as truncation of the cytosolic tail of CD28 disrupts synapse localization without effecting the ability of CD28 to bind CD80.
7139 19017952 Mutation of tyrosine 188 also results in diminished activation of NF-kappaB, suggesting that CD28-mediated localization of PKCtheta to the cSMAC is important for efficient signal transduction.
7140 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).
7141 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.
7142 19027322 Peripheral blood samples were measured by ELISA for plasma levels of IL-2, IL-6, TNF-alpha, IFN-gamma, and IFN-alpha.
7143 19027322 The pattern of production of IFN-gamma was opposite to that of TNF-alpha, but statistical significance was stronger in patients receiving ATT and Dzherelo+Anemin than in Dzherelo group: -34% (P=0.004), +31.9% (P=0.008), and +17.3% (P=0.33), respectively.
7144 19036430 At the lowest antigen dose (0.01 microg/mL), PK3-OVA-poly(I:C) microparticles also enhanced TNF-alpha and IL-2 production in CD8(+) T cells.
7145 19041358 PD also significantly promoted the production of Th1 (IL-2 and IFN-gamma) and Th2 (IL-10) cytokines and up-regulated the mRNA expression of Th1 cytokines (IL-2 and IFN-gamma) in splenocytes from the mice immunized with HBsAg (P<0.001).
7146 19050276 Contrary to the belief that CD4 T cells are protective because they merely maintain the CD8 T cell response and improve Ab production, in this study we provide evidence for the direct antiviral activity of CD4 T cells that functions to protect the host from WNV encephalitis.
7147 19050276 In adoptive transfers, naive CD4 T cells protected a significant number of lethally infected RAG(-/-) mice, demonstrating the protective effect of CD4 T cells independent of B cells and CD8 T cells.
7148 19050276 WNV-specific CD4 T cells produced IFN-gamma and IL-2, but also showed potential for in vivo and ex vivo cytotoxicity.
7149 19073216 An Ad serotype 5 vector containing unique deletions in the E2b region (Ad5 [E1-, E2b-]) has been reported to have several advantages over conventional Adenovirus serotype 5 (Ad5) vectors deleted in only the E1 region (Ad5 [E1-]), including increased carrying capacity and diminished viral late gene expression.
7150 19073216 Multiple immunizations of Ad naïve BALB/c mice with an Ad5 [E1-, E2b]-gag vaccine resulted in higher ELISpot CMI responses as compared to mice immunized with an Ad5 [E1-]-gag vaccine.
7151 19073216 More importantly, multiple immunizations of Ad5 immune BALB/c mice with an Ad5 [E1-, E2b]-gag vaccine resulted in significant increases in ELISpot CMI responses when compared to Ad5 immune mice vaccinated with an Ad5 [E1-]-gag vector.
7152 19073216 Preliminary studies in three Ad5 immune non-human primates (NHP) demonstrated that vaccination with Ad5 [E1-, E2b-]-gag-induced elevated levels of interferon-gamma and IL-2 secreting lymphocytes as assessed by ELISpot assays.
7153 19075247 Activation of RSV-specific T cells producing IFN-gamma and IL-2 was efficiently obtained after immunization with recombinant BCG.
7154 19091993 Splenocytes derived from Fms-like tyrosine kinase receptor 3 (Flt3) ligand-pretreated BALB/c mice were incubated with magnetic beads coated with HCV NS5, lipopolysaccharide (LPS), and/or anti-CD40; purified; and used for immunization.
7155 19091993 Cellular immunity was measured using cytotoxic T-lymphocyte (CTL) and T-cell proliferation assays, intracellular cytokine staining, and a syngeneic tumor challenge using NS5-expressing SP2/0 myeloma cells in vivo.
7156 19091993 Splenocytes isolated from animals vaccinated with DCs containing beads coated with NS5, LPS, and anti-CD40 secreted elevated levels of interleukin-2 (IL-2) and gamma interferon in the presence of NS5.
7157 19091993 The numbers of CD4(+), IL-2-producing cells were increased >5-fold in the group immunized with DCs containing beads coated with NS5, LPS, and anti-CD40, paralleled by an enhanced splenocyte proliferative response.
7158 19091993 Splenocytes derived from Fms-like tyrosine kinase receptor 3 (Flt3) ligand-pretreated BALB/c mice were incubated with magnetic beads coated with HCV NS5, lipopolysaccharide (LPS), and/or anti-CD40; purified; and used for immunization.

7161 19091993 The numbers of CD4(+), IL-2-producing cells were increased >5-fold in the group immunized with DCs containing beads coated with NS5, LPS, and anti-CD40, paralleled by an enhanced splenocyte proliferative response.
7162 19109135 Activated human neonatal CD8+ T cells are subject to immunomodulation by direct TLR2 or TLR5 stimulation.
7163 19109135 In concert with TCR stimulation, only Pam(3)Cys (palmitoyl-3-Cys-Ser-(Lys)(4)) and flagellin monomers significantly enhanced proliferation, CD25(+) expression, IL-2, IFN-gamma, TNF-alpha, and intracellular granzyme B expression.
7164 19109135 TLR2 and TLR5 mRNA was detected in the CD8(+) T cells.
7165 19109135 Blocking studies confirmed that the increase in IFN-gamma production was by the direct triggering of surface TLR2 or TLR5.
7166 19109135 The simultaneous exposure of CD8(+) T cells to both TLR agonists had an additive effect on IFN-gamma production.
7167 19110021 We demonstrate for the first time that treatment with yeast-CEA can activate human DCs, resulting in increases in surface expression of CD80, CD83, CD54, CD58, and MHC class II, and increased production by DCs of IL-12p70, TNF-alpha, IFN-gamma, IL-8, IL-2, IL-13, IL-10, and IL-1beta.
7168 19116444 and IL-4 production than other constructs, except IL-2 production.
7169 19124723 The recently described cytokines IL-19, IL-20, and IL-24 share structural homology with IL-10 and are therefore classified as members of the IL-10 family of cytokines.
7170 19124723 Although it has long been speculated that signaling by their heterodimeric receptor complexes (IL-20R1/IL-20R2 and IL-22R/IL-20R2) influences immunological processes, the target cells for this group of cytokines are still unclear.
7171 19124723 By generating a knockout mouse strain deficient for the common IL-20R beta-chain (IL-20R2), we show that IFN-gamma and IL-2 secretion is significantly elevated after stimulation of IL-20R2-/--deficient CD8 and CD4 T cells with Con A or anti-CD3/CD28 in vitro.
7172 19124723 IL-10 secretion by activated IL-20R2-/- CD4 cells was diminished.
7173 19124723 Consistent with our in vitro results, significantly more Ag-specific CD8 IFN-gamma+ and CD4 IFN-gamma+ T cells developed to locally applied DNA vaccines in IL-20R2-deficient mice.
7174 19124723 Thus, IL-20R2 signaling directly regulates CD8 and CD4 T cell answers in vitro and in vivo.
7175 19124723 For the first time, we provide evidence that IL-19, IL-20, and IL-24 are part of a signaling network that normally down-modulates T cell responses in mice.
7176 19129019 Here, we have investigated the structural and functional relationships of p53, oncogene and interleukin 2 (IL2) proteins using the resonant recognition model (RRM), a physico-mathematical approach based on digital signal processing methods.
7177 19141458 Broad, high-magnitude and multifunctional CD4+ and CD8+ T-cell responses elicited by a DNA and modified vaccinia Ankara vaccine containing human immunodeficiency virus type 1 subtype C genes in baboons.
7178 19141458 The vaccine regimen induced (i) strong T-cell responses, with a median of 4103 spot forming units per 10(6) peripheral blood mononuclear cells by gamma interferon (IFN-gamma) ELISPOT, (ii) broad T-cell responses targeting all five vaccine-expressed genes, with a median of 12 peptides targeted per animal and without any single protein dominating the response, (iii) balanced CD4(+) and CD8(+) responses, which produced both IFN-gamma and interleukin (IL)-2, including IL-2-only responses not detected by the ELISPOT assay, (iv) vaccine memory, which persisted 1 year after immunization and could be boosted further, despite strong anti-vector responses, and (v) mucosal T-cell responses in iliac and mesenteric lymph nodes in two animals tested.
7179 19141458 Together, our data show that a combination of DNA and MVA immunization induced robust, durable, multifunctional CD4(+) and CD8(+) responses in baboons targeting multiple HIV epitopes that may home to mucosal sites.
7180 19157569 Of 11 vaccine adjuvants tested, five (i.e. interleukin-2 (IL-2), IL-12, interferon alpha (IFNalpha), polyinosinic and polycytidylic acid, and cytidine-phosphate-guanosine oligodeoxynucleotides (CpG ODN)) significantly enhance CMI response to PRRSV vaccines.

7207 19224636 TB cases had significantly higher levels of IFN-gamma(+)TNF-alpha(+)IL-2(+)CD4(+)T cells compared with contacts.

7214 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).
7215 19248157 No difference was observed in the expression levels of the Th2-type cytokines (IL-4 and IL-10; P > 0.05).
7216 19264776 Peptides containing the epitopes stimulated RSV-specific CD4 T cells to produce gamma interferon (IFN-gamma), interleukin 2 (IL-2), and other Th1- and Th2-type cytokines in an I-A(b)-restricted pattern.
7217 19264776 Peptide-activated CD4 T cells from lungs were more activated and differentiated, and had greater IFN-gamma expression, than CD4 T cells from the spleen, which, in contrast, produced greater levels of IL-2.
7218 19264776 In addition, M(209-223) peptide-activated CD4 T cells reduced IFN-gamma and IL-2 production in M- and M2-specific CD8 T-cell responses to D(b)-M(187-195) and K(d)-M2(82-90) peptides more than M2(25-39) peptide-stimulated CD4 T cells.

7225 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.
7226 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.
7227 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.

7233 19306502 T cell expression of the inhibitory receptor programmed death-1 (PD-1) and inhibition of effector T cells (Teffs) by CD4+Foxp3+Tregs are among the many described mechanisms for achieving a balanced immune response.
7234 19306502 In this issue of the JCI, Franceschini et al. extend our understanding of how Tregs are modulated during chronic HCV infection by demonstrating that Treg proliferation is inhibited by PD-1 and that this inhibition is mediated by a potentially novel mechanism involving the prevention of IL-2-driven STAT-5phosphorylation.
7235 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.
7236 19307173 GGS altered the expression of IL-4 and IL-12 in T lymphocytes.
7237 19321612 Persistent cytokine responses of antigen-specific CD4(+) and CD8(+) T cells of the central memory as well as the effector memory phenotype, capable of simultaneously eliciting multiple cytokines (IFN-gamma, interleukin 2, and tumor necrosis factor alpha), were induced.
7238 19342966 Whereas a wealth of information is available on how these adjuvants affect CD4 T cell responses, their effects on engaging CD8 T cell immunity are not completely understood.
7239 19342966 Our data show that CFA-induced CD8 T cells to proliferate, mediate DTH, and to secrete interferon-gamma, interleukin (IL)-2 and IL-17.
7240 19357166 Acquisition of polyfunctionality by Epstein-Barr virus-specific CD8+ T cells correlates with increased resistance to galectin-1-mediated suppression.
7241 19357166 More importantly, ex vivo stimulation of these T cells with an adenoviral vector encoding multiple minimal CD8(+) T-cell epitopes as a polyepitope, in combination with a gammaC cytokine, interleukin-2, restored polyfunctionality and shielded these cells from the inhibitory effects of galectin-1.
7242 19357176 Here we show that a primary CD8(+) T-cell response can be induced by HIV-1 peptide-loaded DC derived from blood monocytes of HIV-1-negative adults and neonates (moDC) and by Langerhans cells (LC) and interstitial, dermal-intestinal DC (idDC) derived from CD34(+) stem cells of neonatal cord blood.
7243 19357176 Optimal priming of single-cell gamma interferon (IFN-gamma) production by CD8(+) T cells required CD4(+) T cells and was broadly directed to multiple regions of Gag, Env, and Nef that corresponded to known and predicted major histocompatibility complex class I epitopes.
7244 19357176 Polyfunctional CD8(+) T-cell responses, defined as single-cell production of more than one cytokine (IFN-gamma, interleukin 2, or tumor necrosis factor alpha), chemokine (macrophage inhibitory factor 1beta), or cytotoxic degranulation marker CD107a, were primed by moDC, LC, and idDC to HIV-1 Gag and reverse transcriptase epitopes, as well as to Epstein-Barr virus and influenza A virus epitopes.
7245 19414123 There is potential utility for antifibrinolytic drugs, cytokine supplementation (IL2/IFN), and Cox-2 inhibitors.
7246 19428306 In this review, we discuss the four major gammaC cytokines that have proven activity in or potential for immunotherapy: IL-2, IL-7, IL-15 and IL-21.
7247 19428898 In BALB/c mice the vaccine preparation induced antigen-specific multi-functional CD4(+) T cells capable of producing IFN-gamma, IL-2, and/or TNF-alpha upon antigen re-exposure, and MPL-SE was indispensable to direct immune responses to SMT towards Th1.
7248 19445368 Later, blockade of the homeostatic interleukin-7/CD4 loop contributes to rendering this CD4 lymphopenia irreversible.
7249 19445368 Also, these "central memory" CD4 T lymphocytes produce large quantities of IL-2, that they use in an autocrine manner, stimulating their self-renewal and ensuring their long-term survival.
7250 19457773 The DNA vaccine induced T-cell-mediated immunity as shown by significantly increased NO concentrations, cytokine gene (IL-2 and IFN-gamma) expression, and NcSRS2 protein-stimulated lymphocyte proliferation in mice immunised with the DNA vaccine.

7260 19467215 Co-injection of pVAX/mIL-18 significantly increased the production of IFN-gamma and IL-2 compared with pVAX/SjFABP alone, indicating that IL-18 enhances the Th1-dominant immune response.
7261 19467927 Although dendritic cells readily upregulated maturation and activation markers in response to K88 stimulation, accompanied by secretion of interleukin (IL)-12, IL-6, IL-10, and tumour necrosis factor, restimulation of T cells from mice having received EcN-K88 with K88-loaded dendritic cells did not result in detectable T cell proliferation and IL-2 secretion, but rather induced an IL-10 bias.
7262 19483643 Granulocyte macrophage-colony stimulating factor plus interleukin-2 plus alpha-interferon plus 5-fluorouracil in the treatment of metastatic renal cell cancer: induction of CD80/86+ T cells indicates adverse outcome.

7267 19483643 This clinical phase 1/2 chemoimmunotherapy trial in metastatic RCC used sequential application of alpha-interferon /5-fluorouracil followed by granulocyte macrophage-colony stimulating factor/interleukin-2.
7268 19483649 Using this model, we found that induction of lymphopenia before adoptive transfer of ex vivo anti-CD3/CD28 activated and interleukin-2 expanded D5-G6 tumor draining lymph node cells enhanced the antitumor efficacy of the infused cells in both pulmonary metastases and subcutaneous D5 bearing mice.
7269 19483649 This enhanced antitumor activity was associated with a selective increase in proliferation, accumulation, and function of CD4+ rather than CD8+ infused cells.
7270 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.
7271 19494330 Characterization of the CD4 memory T cells by multicolor flow cytometry demonstrated that the long-lived memory population consisted almost exclusively of TNF-alpha(+)IL-2(+) and IFN-gamma(+)TNF-alpha(+)IL-2(+) multifunctional T cells.
7272 19494330 Long-term memory induced by the BCG vaccine contained fewer multifunctional T cells and was biased toward effector cells mainly of the TNF-alpha(+)IFN-gamma(+)-coexpressing subset.
7273 19508869 In contrast to rROP2 stimulating only the specific IL-2 release, rROP4 and crude toxoplasma lysate antigen (TLA) used as a source of native forms of the parasite proteins induced significant proliferation of splenocytes and specific production of IFN-gamma as well as IL-2, the Th1-type cytokines.
7274 19523909 The IN defective vector was able to efficiently elicit specific and long-lasting polyfunctional immune responses as evaluated by enzyme-linked immunospot (ELISPOT) assays for interferon-gamma (IFN-gamma) in spleens, bone marrow (BM) and draining lymph nodes, and by intracellular staining (ICS) for IFN-gamma, Interleukin-2 (IL-2) and tumor necrosis factor (TNF-alpha) in both splenocytes and BM cells without integration of the vector into the host genome.
7275 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.
7276 19524654 Further, cytokine levels-interferon gamma and interleukin-2-were increased in spleen homogenates.
7277 19526193 Cytometry analysis indicated that the majority of memory CD8(+) T cells produced IFN-gamma, whereas memory CD4(+) T cells produced IFN-gamma, IL-2 or TNF-alpha.
7278 19540000 The bIL18 rDNA induced production of the Th1 type cytokines IL2 and IFNgamma, and ClfA(221-550) and bIL18 synergistically stimulated T-lymphocyte proliferation.
7279 19540885 The Th1 (TNF-alpha, IL-12p70, IFN-gamma, IL-2) and Th2 (IL-10, IL-6) cytokine profiles were analyzed after stimulation of spleen cells from mice immunized with purified RF-412 protein.
7280 19540920 The Escherichia coli produced recombinant IL-2 was shown to increase the expression of two transcription factors, STAT5 and Blimp-1, known to be involved in IL-2 signalling in mammals, as well as IFN-gamma, gIP and IL-2 itself.
7281 19543225 In this Review, we focus on our current understanding of the distinct and overlapping effects of interleukin-2 (IL-2), IL-7, IL-9, IL-15 and IL-21, as well as the IL-7-related cytokine thymic stromal lymphopoietin (TSLP), on the survival and proliferation of conventional alphabeta T cells, gammadelta T cells and regulatory T cells.
7282 19554480 Several modalities of vaccines have been tested against lipoproteins, cholesterol, molecules involved in cholesterol metabolism, atherosclerosis-associated microorganisms, and other molecules (heat shock protein, CD99, vascular endothelial growth factor-receptor, interleukin-2), with promising results.
7283 19556898 T-cell activation requires both antigen presentation to the T-cell receptor and a second signal mediated by CD80 and CD86 on antigen-presenting cells and CD28 on the T cell.
7284 19556898 Ligand binding to CD28 on the T-cell surface leads to T-cell proliferation and expression of activating cytokines such as interleukin-2.
7285 19556898 Cytotoxic T-lymphocyte antigen-4 (CTLA-4), an inhibitory protein expressed on T cells, competes for the same ligands as CD28 and modulates T-cell activation.
7286 19556898 Because CTLA-4 has a significantly higher binding efficiency than CD28, CTLA-4 is critical in maintaining immune tolerance to self-antigens and may also limit responses to tumor antigens and vaccine therapy.
7287 19559111 The results showed that immunization with chimeric DNA vaccine construct resulted in stronger IFN-gamma and IL-2 response against kinesin (3012+/-102 and 367.5+/-8.92pg/ml) and ESAT-6 (1334+/-46.5 and 245.1+/-7.72pg/ml) in comparison to the individual vaccine constructs.
7288 19559111 The reciprocal immune response (IFN-gamma and IL-2) against individual construct was lower (kinesin motor domain: 1788+/-36.48 and 341.8+/-9.801pg/ml and ESAT-6: 867.0+/-47.23 and 170.8+/-4.578pg/ml, respectively).

7290 19559111 The reciprocal immune response (IFN-gamma and IL-2) against individual construct was lower (kinesin motor domain: 1788+/-36.48 and 341.8+/-9.801pg/ml and ESAT-6: 867.0+/-47.23 and 170.8+/-4.578pg/ml, respectively).
7291 19564375 The cell-mediated immune (CMI) response was characterized by significant gamma interferon (IFN-gamma), interleukin 12 (IL-12), IL-2, IL-10, and IL-17 production.
7292 19564375 Several antibody and CMI cytokine responses were examined for correlates of protection, and prechallenge IFN-gamma(+) or IFN-gamma-, IL-2-, and tumor necrosis factor alpha-triple-positive CD4 cells in blood were statistically associated with protection.
7293 19564375 The cell-mediated immune (CMI) response was characterized by significant gamma interferon (IFN-gamma), interleukin 12 (IL-12), IL-2, IL-10, and IL-17 production.
7294 19564375 Several antibody and CMI cytokine responses were examined for correlates of protection, and prechallenge IFN-gamma(+) or IFN-gamma-, IL-2-, and tumor necrosis factor alpha-triple-positive CD4 cells in blood were statistically associated with protection.
7295 19577301 However, there were no major changes in the expression levels of transcripts for cell surface proteins (MHC I, MHC II 2 beta-chain, TCR-beta, TLR-7, DCAR, CD44, and CD58) and cytokines (IL-2, IFN-gamma, RANTES, MIP-1beta-like and MCP-1 like chemokines).
7296 19585669 Production of primary interferon (IFN)-gamma and interleukin (IL)-2 in GRA4-stimulated splenocytes from vaccinated mice suggested a modulated Th1-type response. 72.7% of C57BL/6 mice immunized with liposome-encapsulated pGRA4 survived the challenge with 80 tissue cysts of ME49 strain, whereas C57BL/6 mice immunized with pGRA4 had only a survival rate of 54.5%.
7297 19587528 The Mtb72F antigen induced good production of IL-2 and IFNgamma in the ELISPOT assay and CD4(+) T cells expressing at least two activation markers (mainly CD40-L and IL-2) were observed with ICS.
7298 19592661 Upon virulent challenge, the immunized mice displayed in the CD4(+) T cell population a significant increase of single and multiple cytokine (IFN-gamma, IL-2, and TNF) producing cells and IFN-gamma/IL10 ratio.
7299 19620310 Importantly, a simple synthetic analog of MMG, based on a 32 carbon mycolic acid, was found to give rise to comparable high Th1-biased responses with a major representation of polyfunctional CD4 T cells coexpressing IFN-gamma, TNF-alpha, and IL-2.
7300 19620314 The vaccine-promoted response consists mainly of double- (TNF-alpha and IL-2) or triple-positive (IFN-gamma, TNF-alpha, and IL-2) polyfunctional T cells.
7301 19628058 WSL enhanced Th1 cytokine IFN-gamma expression in Con A primed splenocytes in vitro.
7302 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.
7303 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.
7304 19628058 Further, the effect of WSL in immunized mice elicited up-regulation of beta-integrins LFA (CD11a) and Mac-1 (CD11b) in splenocytes.
7305 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.
7306 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.
7307 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.
7308 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.
7309 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.
7310 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.
7311 19651643 PD1 blockade reverses the suppression of melanoma antigen-specific CTL by CD4+ CD25(Hi) regulatory T cells.
7312 19651643 Regulatory CD4(+)CD25(Hi) T cells (Treg) and programmed death-1 (PD-1) molecule have emerged as pivotal players in immune regulation.
7313 19651643 We identified Treg in the circulation of vaccinated melanoma patients and detected PD-1 expression on vaccine-induced melanoma antigen-specific CTLs, as well as on and within Treg from patients' peripheral blood.
7314 19651643 PD-1 blockade promoted the generation of melanoma antigen-specific CTLs and masked their inhibition by Treg.
7315 19651643 The mechanisms by which PD-1 blockade mediated immune enhancement included direct augmentation of melanoma antigen-specific CTL proliferation, heightening their resistance to inhibition by Treg and direct limitation of the inhibitory ability of Treg.
7316 19651643 PD-1 blockade reversed the increased expression of PD-1 and PD-L1 on melanoma antigen-specific CTL by Treg, rescued INF-gamma and IL-2 or INF-gamma and tumor necrosis factor-alpha co-expression and expression of IL-7 receptor by melanoma antigen-specific CTL which were diminished by Treg.
7317 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.
7318 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.
7319 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).
7320 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.
7321 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.
7322 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).
7323 19652028 Murine splenocytes expressing a transgenic TCR specific for CTL peptide OVA(257-264) (SIINFEKL) demonstrated up to 25-fold greater IFN-gamma and IL-2 secretion when treated in vitro with alpha(2)M*-OVA compared with soluble OVA.
7324 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.
7325 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.
7326 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.

7331 19679214 Our results show that Fluzone combined with lipid A plus an emulsion effectively leads to greater vaccine-specific IgG2a and IgG titers, enhances hemagglutination-inhibition titers and induces Type 1 cytokine responses (IFN-gamma and IL-2) to each of the Fluzone components.
7332 19680453 The delivery of cytokines, either by single cytokines, for example, interleukin-2, interleukin-12, interferon-gamma, interferon-alpha, or by a biologic mix of multiple cytokines, such as IRX-2, may result in tumor rejection and durable immune responses.
7333 19706905 Antigen-specific antibodies and Th1 cytokines, interleukin-2, interferon-gamma, and tumor necrosis factor-alpha were induced in rVCG-TBCA2-immunized mice and in vitro on antigen stimulation of splenic immune T cells, but the corresponding Th2-type response was unremarkable.

7376 19752747 A patient with metastatic melanoma who had progressive disease after prior surgical resections, high dose interleukin-2, and anti-cytotoxic T lymphocyte antigen-4 antibody received sequential treatments with autologous tumor infiltrating lymphocytes that recognized the gp100 melanocyte differentiation antigen.
7377 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.
7378 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.
7379 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.
7380 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.

7389 19769731 The human cancer antigen mesothelin is more efficiently presented to the mouse immune system when targeted to the DEC-205/CD205 receptor on dendritic cells.
7390 19769731 To develop a tumor vaccine directly targeting tumor antigen to dendritic cells in situ, we engineered human mesothelin (MSLN) into an antibody specific for mouse DEC-205, a receptor for antigen presentation.
7391 19769731 We then characterized both T cell and humoral responses to human MSLN and compared immunizing efficacy of DEC-205-targeted MSLN to nontargeted protein after a single-dose immunization.
7392 19769731 Targeting human MSLN to DEC-205 receptor induced stronger CD4(+) T-cell responses compared to high doses of mesothelin protein.
7393 19769731 Approximately 0.5% CD4(+) T cells were primed to produce IFN-gamma, tumor necrosis factor-alpha, and IL-2 via intracellular cytokine staining, and the T cells also could proliferate rapidly.
7394 19769731 Targeting MSLN protein to DEC-205 receptor also resulted in cross-presentation to CD8(+) T cells.
7395 19769731 In summary, targeting of MSLN to DEC-205 improves the induction of CD4(+) and CD8(+) T-cell immunity accompanied by an antibody response.
7396 19769731 DEC-205-targeting could be valuable for enhancing immunity to MSLN in cancers where this nonmutated protein is expressed.

7406 19812258 The levels of interleukin-2, gamma interferon, and the ratios of immunoglobulin G2a (IgG2a)/IgG1 clearly showed that cocktail DNA vaccines induced CD4(+) Th1-type responses.
7407 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).
7408 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).
7409 19837090 Significant T cell responses specific for the vectored vaccine antigens were demonstrated by IFNgamma ELISPOT and intracellular cytokine staining (ICS) for IFNgamma and IL-2, the ICS being associated with increased time to parasitaemia following subsequent challenge.
7410 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.
7411 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.
7412 19845795 Some donors, however, also responded with late IFN-gamma production, suggesting that the regulation by IL-10 could be overridden.
7413 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.
7414 19858306 Kinetic analysis showed that the MVA boost made the adenoviral-primed T cells markedly more polyfunctional, with the number of gamma interferon (INF-gamma), tumor necrosis factor alpha (TNF-alpha), and interleukin-2 (IL-2) triple-positive and INF-gamma and TNF-alpha double-positive cells increasing over time, while INF-gamma single-positive cells declined with time.
7415 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.

7423 19863514 Intradermal injections of polyarginine-containing immunogenic antigens preferentially elicit Tc1 and Th1 activation and antitumour immunity.
7424 19863514 Background We previously have shown that nona-arginine protein transduction domain (R9-PTD) induced efficient protein-antigen (Ag) transduction of dendritic cells (DCs) in vitro, resulting in the efficient induction of strong Ag-specific immune responses mediated by CD8+ and CD4+ T cells and in superior antitumour effects in vivo in cancer-bearing mice.
7425 19863514 The i.d. injections of rR9-OVA also induced inflammatory cell infiltrates containing neutrophils, monocytes and lymphocytes, as well as production of inflammatory cytokines such as interferon (IFN)-gamma, interleukin-2 and IFN-inducible protein 10, with presenting SIINFEKL epitopes on major histocompatibility complex (MHC) class I molecules at the injection area. i.t. injections of rR9-OVA into EG.7 tumour mass significantly suppressed tumour growth, and these effects were completely abrogated by the depletion of CD8+ T cells.

7430 19877124 Concluding, L19-IL2 and L19mTNFalpha efficiently cooperate in determining a high percentage of NB cure that, in our experimental models, is strongly associated to the generation of adaptive immunity involving CD4(+) and CD8(+) T cells.

7441 19880570 In non-systemic lupus erythematosus populations, vaccines against oxidized low-density lipoprotein, beta-2-glycoprotein I, heat shock proteins, lipoproteins, cholesterol, molecules involved in cholesterol metabolism, and other molecules (CD99, vascular endothelial growth factor-receptor, and interleukin-2) have been tested, with promising results.
7442 19895246 In the past decade progress has been made, ranging from rather nonspecific stimulations of the immune system with IL-2 and IFN-alpha to more specific approaches based on vaccination with tumor antigens.
7443 19901066 Polyfunctional CD4 lymphocytes, defined as producing intracellular interleukin 2 (IL-2), gamma interferon (IFN-gamma), and tumor necrosis factor alpha simultaneously, had a frequency of 137 per 400,000 events among peripheral blood mononuclear cells (PBMC) of immune donors compared to 11 per 400,000 PBMC from nonimmune donors (P = 0.03).
7444 19901066 When monocyte-derived mature dendritic cells pulsed with T27K (mDC(T27K)) were used for antigen presentation, the frequency of polyfunctional CD4 T lymphocytes did not significantly increase for either group, although mDC(T27K) did significantly increase the concentrations of IL-2 and IFN-gamma released by PBMC from nonimmune donors (P = 0.02).
7445 19901066 After in vitro stimulation with T27K, polyfunctional CD4 and CD8 lymphocytes of PBMC from immune donors had a mixture of low- and high-expression CCR7 cells, suggesting both effector and central memory, compared with predominantly high-expression CCR7 cells when PBMC were incubated with the mitogen phytohemagglutinin (P = 0.03).

7450 19902255 A TLR3 gene promoter region SNP (rs5743305, -8441A > T) was associated with rubella-specific GM-CSF secretion.
7451 19902255 Importantly, SNPs in the TRIM5 gene coding regions, rs3740996 (His43Tyr) and rs10838525 (Gln136Arg), were associated with an allele dose-related secretion of rubella virus-specific TNF-alpha and IL-2/GM-CSF, respectively, and have been previously shown to have functional consequences regarding the antiviral activity and susceptibility to HIV-1 infection.
7452 19902255 We identified associations between individual SNPs and haplotypes in, or involving, the RIG-I (DDX58) gene and rubella-specific TNF-alpha secretion.

7457 19923459 Soluble B and T lymphocyte attenuator possesses antitumor effects and facilitates heat shock protein 70 vaccine-triggered antitumor immunity against a murine TC-1 cervical cancer model in vivo.
7458 19923459 B and T lymphocyte attenuator (BTLA)-herpesvirus entry mediator (HVEM) signaling coinhibitory pathway is believed to impair antitumor immune competences.
7459 19923459 To address this issue, we constructed a eukaryotic expression plasmid (psBTLA) that expressed the extracellular domain of murine BTLA (soluble form of BTLA), which could bind HVEM, the ligand of BTLA, and block BTLA-HVEM interactions.
7460 19923459 The data in this study showed that treatment by injection of psBTLA resulted in down-regulation of IL-10 and TGF-beta and promotion of dendritic cell function by increasing the expression of B7-1 and IL-12, but the adaptive antitumor immune responses achieved by psBTLA administration alone were limited and could not eradicate the tumor effectively.
7461 19923459 Next, we evaluated the immunotherapeutic efficacy and mechanism of combination therapy of heat shock protein 70 (HSP70) vaccine/psBTLA by using murine TC-1 cervical cancer mice as an ectopic tumor model.
7462 19923459 Our in vivo studies revealed that treatment with HSP70 vaccine alone did not lead to satisfactory tumor growth inhibition, whereas cotreatment with psBTLA significantly improved antitumor immunity and compensated the deficiency of HSP70 vaccine by increasing the expression of Th1 cytokines, IL-2, and IFN-gamma and decreasing transcription levels of IL-10, TGF-beta, and Foxp3 in the tumor microenvironment.
7463 19933869 This longitudinal analysis showed the following. 1) Memory CD8(+) T cells appear to pass through an effector phase and then gradually down-regulate expression of activation markers and effector molecules. 2) This effector phase was characterized by down-regulation of CD127, Bcl-2, CCR7, and CD45RA and was followed by a substantial contraction resulting in a pool of memory T cells that re-expressed CD127, Bcl-2, and CD45RA. 3) These memory cells were polyfunctional in terms of degranulation and production of the cytokines IFN-gamma, TNF-alpha, IL-2, and MIP-1beta. 4) The YF-17D-specific memory CD8(+) T cells had a phenotype (CCR7(-)CD45RA(+)) that is typically associated with terminally differentiated cells with limited proliferative capacity (T(EMRA)).
7464 19950184 IL-7 is superior to IL-2 for ex vivo expansion of tumour-specific CD4(+) T cells.
7465 19950184 While protocols suitable for the expansion of cytotoxic CD8(+) T cells are currently available, data on tumour-specific CD4(+) T cells remain scarce.
7466 19950184 We report here that CD4(+) T cells sensitized to tumour-associated Ag in vivo, proliferate in vitro in response to IL-7 without the need for exogenous Ag stimulation and accumulate several folds while preserving a memory-like phenotype.
7467 19950184 Also IL-2, previously used to expand anti-tumour CTL, promotes tumour-specific CD4(+) T-cell accumulation.
7468 19950184 However, IL-7 is superior to IL-2 at preserving lymphocyte viability, in vitro and in vivo, maintaining those properties, that are required by helper CD4(+) T cells to confer therapeutic efficacy upon transplantation in tumour-bearing hosts.
7469 19950184 Together our data support a unique role for IL-7 in retrieving memory-like CD4(+) T cells suitable for adoptive T-cell therapy.

7482 20002303 The DC population was expanded in BALB/C mice (H-2(d) ) by hydrodynamic injection of a plasmid pUMVC3-hFLex expressing the secreted portion of the human Fms-like tyrosine kinase receptor-3 ligand (hFlt3).
7483 20002303 Cellular immune responses were determined with respect to secretion of INFγ and IL2 by CD4(+) cells and cytotoxic T-lymphocyte (CTL) assays in vitro; inhibition of tumour cell growth was employed for the assessment of CD8(+) generated activity in vivo.
7484 20002303 We found that Flt3L treatment expanded the DC population in the spleen to 43%, and such cells displayed a striking upregulation of CD86 as well as CD80 and CD40 co-stimulating molecules.
7485 20006311 ESAT-6 also inhibited T-cell production of IL-17 and TNF-a, but not IL-2.
7486 20006311 ESAT-6 reduced IFN-gamma mRNA levels by inhibiting the expression of the transcription factors, ATF-2, c-Jun and CREB, which upregulate IFN-gamma gene expression in T cells through binding to the IFN-gamma proximal promoter.
7487 20017188 Multiple CD4+ T-cell subsets, based on expression of IFN-gamma, TNF-alpha, IL-2, IL-17 and GM-CSF, were induced.

7489 20017188 A novel CD4+ cell subset co-expressing these three Th1 cytokines and IL-17 was induced in adolescents, while a novel CD4+ T-cell subset co-expressing Th1 cytokines and GM-CSF was induced in children.
7490 20017188 Multiple CD4+ T-cell subsets, based on expression of IFN-gamma, TNF-alpha, IL-2, IL-17 and GM-CSF, were induced.

7493 20029165 CD45RO+/KLRG1+/CD57+/CD28-), enhanced IL-2 production and T-lymphocyte expression of the IL-2 receptor, longer chromosome telomere lengths in blood leukocytes and in vivo immune responses to vaccines and recall antigens.
7494 20038483 IL-7 protects both B and T lymphocytes, but IL-2, IL-10, keratinocyte growth factor, thymic stromal lymphopoietin, as well as leptin and growth hormone also have a stimulatory effect on thymopoiesis.
7495 20039320 Transient depletion of CD4(+) T cells augments IL-21-based immunotherapy of disseminated neuroblastoma in syngeneic mice.
7496 20039320 IL-21 is a member of the IL-2 cytokine family, produced by CD4+ T cells.
7497 20039320 Anti-CD25 mAb, indeed, only partially depleted CD4+CD25+FoxP3+ Treg cells, whereas anti-CD4 mAb was more effective in this respect, leading to 90% depletion of Treg cells.
7498 20039320 Spleen cells from mice receiving Neuro2a/IL-21 vaccination showed increased expression of IFN-alpha2, -beta1 and -gamma mRNA.
7499 20039320 Moreover, mice receiving vaccine therapy alone or vaccine+anti-CD4 mAb showed increased IFN-gamma serum levels and IFN-gamma-producing CD8+ T cells were found in spleen cells.
7500 20039320 In conclusion, anti-CD4 mAb potentiated IL-21-based IT by removing Treg cells and/or their precursors and other potentially immune-suppressive CD4+ cell subsets, thus allowing the development of an IL-21-driven CD8+ T cell response, which mediates NB rejection.
7501 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.
7502 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.

7505 20072155 Selective elimination of a chemoresistant side population of B-CLL cells by cytotoxic T lymphocytes in subjects receiving an autologous hCD40L/IL-2 tumor vaccine.
7506 20072155 To discover whether drug-resistant malignant SP cells are nonetheless sensitive to immune-mediated killing, we first established the presence of a malignant CD5(+)CD19(+) SP subset in the blood of 18/21 subjects with B-cell chronic lymphocytic leukemia (B-CLL).
7507 20072155 We examined the fate of these cells in six of these individuals who received autologous human CD40 ligand and interleukin-2 (hCD40L/IL-2) gene-modified tumor cells as part of a tumor vaccine study.
7508 20072155 Vaccinated patients showed an increase in B-CLL-reactive T cells followed by a corresponding decline in circulating CD5(+)CD19(+) SP cells.
7509 20072155 Elimination of SP cells is likely triggered by their increased expression of target antigens, such as receptor for hyaluronan-mediated motility (RHAMM), after stimulation of the malignant cells by hCD40L, as CD8(+) RHAMM-specific T cells could be detected in the peripheral blood of immunized patients and were associated with the decline in B-CLL SP cells.

7525 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).
7526 20092022 A virosomal formulated Her-2/neu multi-peptide vaccine induces Her-2/neu-specific immune responses in patients with metastatic breast cancer: a phase I study.
7527 20092022 We have previously shown in mice that vaccination with three Her-2-peptides representing B-cell epitopes of the extracellular domain of Her-2/neu induces Her-2/neu-specific IgG antibodies with strong anti-tumor activity in vitro and in vivo.
7528 20092022 Cellular immune responses, as measured by in vitro production of IL-2, IFN-c, and TNF-a of PBMCs showed a marked increase after vaccination in the majority of vaccinees.
7529 20092022 Notably, the number of CD4+CD25+Foxp3+T regulatory cells, which were significantly increased compared to healthy controls prior to vaccination, was markedly reduced following vaccination.
7530 20093205 A significant decrease in parasite burden was seen in vaccinees over the infected controls on all post challenge days and was found that maximum protection was provided by 78kDa+rIL-12 vaccine and it was highly immunogenic as depicted by the reduction in parasite load (71-94.8%), reduction in infection rate of peritoneal macrophages (92.9-98%), enhanced DTH response (6.5-10.5 fold), increase in IgG2a anti-leishmanial antibody production (3-3.7 fold) and up-regulation of IFN-gamma (3.7-6.5 fold) and IL-2 levels (7.7-12.3 fold), which demonstrate the generation of protective Th1 type of immune response.
7531 20096608 CD25, the high-affinity interleukin-2 (IL-2) receptor alpha chain, is rapidly upregulated by antigen-specific CD8(+) T cells after T cell receptor stimulation.
7532 20096608 At this time when there is distinct heterogeneity in CD25 expression, examination of the in vivo fate of effector cells revealed that CD25(lo) cells, which are relatively less sensitive to IL-2, preferentially upregulate CD127 and CD62L and give rise to functional long-lived memory cells.
7533 20096608 In contrast, CD25(hi) cells perceiving prolonged IL-2 signals proliferate more rapidly, are prone to apoptosis, exhibit a more pronounced effector phenotype, and appear to be terminally differentiated.

7540 20099135 The activity of several potent adjuvants, including incomplete Freund's adjuvant, CpG oligodeoxynucleotides, and alum, has been shown to be due at least in part to the induction of cytokines, including type I interferons (IFNs), IFN-gamma, interleukin-2 (IL-2), and IL-12, that play key roles in the regulation of innate and adaptive immunity.
7541 20099135 Although a number of cytokines including IFN-alpha, IFN-gamma, IL-2, IL-12, IL-15, IL-18, IL-21, GM-CSF, and Flt-3 ligand have been shown to potentiate the immune response to vaccination in various experimental models, the full potential of cytokines as vaccine adjuvants remains to be established.

7545 20100932 Costimulatory signals via B7/CD28 family molecules (signal 2) are critical for effective adaptive CD8(+) T cell immune responses.
7546 20100932 In acute hepatitis C virus (HCV) infection, programmed death receptor 1, an inhibitory receptor in the CD28 family, is highly expressed on virus-specific CD8(+) T cells, yet vigorous immune responses often develop.
7547 20100932 In this study, we found that CD86 was highly expressed on HCV-specific CD8(+) T cells early in acute HCV infection and was lost on transition to chronic HCV infection; the expression of CD86 was different from other activation markers, because expression was delayed after in vitro TCR stimulation and required sufficient IL-2 signaling; and HCV-specific CD8(+) T cells in the liver of patients with chronic HCV infection were highly activated (CD69, CD38, and HLA-DR expression), but only a minority expressed CD86 or showed evidence of recent IL-2 signaling (low basal phosphorylated STAT5), despite persistent viremia.

7560 20117268 BTV-1 vaccination induced significant cell-mediated immunity (CMI) as determined by lymphoproliferative responses, and increased CD8 T cell, IL-2 and IFN-gamma responses.
7561 20117268 Both naïve and immunized sheep also showed increased CD4 T cell, IL-12 and IFN-alpha responses.
7562 20117947 The results showed a robust rubella-specific inflammatory cytokine response characterized by high median [inter-quartile range (IQR)] secretion levels (in pg/mL) of IL-6 [3681.0 (3160.0, 4052.0)], GM-CSF [28.0 (23.6, 32.6)], and TNF-alpha [29.7 (-7.0, 89.2)].
7563 20117947 We also detected modest levels of rubella-specific secretion of Th1 cytokines IL-2 and IFN-gamma, while IL-12p40 was undetectable.
7564 20117947 Age at vaccination, enrollment, and time elapsed between last vaccination and enrollment was significantly associated with the outcome of IL-2, IL-6, and IFN-gamma secretion.
7565 20117947 The results showed a robust rubella-specific inflammatory cytokine response characterized by high median [inter-quartile range (IQR)] secretion levels (in pg/mL) of IL-6 [3681.0 (3160.0, 4052.0)], GM-CSF [28.0 (23.6, 32.6)], and TNF-alpha [29.7 (-7.0, 89.2)].

7568 20121402 In comparison to concordant patients, discordant patients showed poor lymphocyte proliferation, lower secretion of IL-2 and IFN-gamma, a lower percentage of perforin and granzyme-B-producing CD8 T cells, and poor differentiation of effector memory CD8 T(EM) cells into CD8 T(EMRA) cells in in-vitro stimulation assays, especially against HIV-1 Gag p24 and one of its peptide pools.
7569 20121402 Our results suggest that prolonged suppression of plasma viremia alone does not warrant good qualitative and quantitative CD8 T-cell responses to HIV-1, implying that CD4 T cells are required for maintenance of protective CD8 T-cell responses.
7570 20130127 The cytokines studied included interleukin-2 (IL-2), IL-4, and IL-10.
7571 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.
7572 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).
7573 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.
7574 20130127 The cytokines studied included interleukin-2 (IL-2), IL-4, and IL-10.
7575 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.

7578 20130130 Peripheral blood mononuclear cells (PBMCs) from healthy donor women were stimulated in vitro with HPV-16 VLPs (2.5 microg/ml) in the presence of E2 and P4 administered either alone or in combination; and lymphoproliferation, cytokine production, transcription factor expression, and steroid hormone receptor expression were analyzed.
7579 20130130 HPV-16 VLPs significantly increased the levels of lymphoproliferation, proinflammatory cytokine (gamma interferon [IFN-gamma], interleukin-1beta [IL-1beta], IL-2, IL-6, IL-8, IL-12p70, IL-17, tumor necrosis factor alpha [TNF-alpha]) production, anti-inflammatory cytokine (IL-1ra, IL-10) production, and the expression of Eralpha and Erbeta but decreased the levels of Foxp3 expression and production of transforming growth factor beta (TGF-beta).
7580 20130130 Exposure of PBMCs to E2 and P4 either alone or in combination significantly decreased the levels of lymphoproliferation and production of proinflammatory cytokines (IFN-gamma, IL-12p70, TNF-alpha) but increased the levels of production of IL-10 and TGF-beta and the expression of Foxp3 in response to HPV-16 VLPs.
7581 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.

7583 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.
7584 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.
7585 20159051 Four weeks later, the ConA-, LPS-, and OVA-induced splenocyte proliferation, OVA-specific antibodies levels (IgG, IgG1, and IgG2a) in serum, IL-2, and TNF-alpha were significantly enhanced by PCS at a high dose compared to that induced by Quil A.
7586 20174562 Tetramer analysis further showed that up to 16.8% of all circulating CD3(+)CD8(+) T cells were specific for the single HLA-B*3501-restricted epitope Gn(465-473) years after the acute infection.
7587 20174562 Remarkably, Gn(465-473)-specific cells readily secreted IFN-gamma, granzyme B and TNF-alpha but not IL-2 upon stimulation and showed a 'revertant' CD45RA(+)CD27(-)CD28(-)CCR7(-)CD127(-) effector memory phenotype, thereby resembling a phenotype seen in other latent virus infections.
7588 20177910 Levels of IgG antibody, gamma-interferon (IFN-gamma), interleukin-2 (IL-2), interleukin-4, and interleukin-10 were detected.
7589 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.
7590 20177910 Levels of IgG antibody, gamma-interferon (IFN-gamma), interleukin-2 (IL-2), interleukin-4, and interleukin-10 were detected.
7591 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.
7592 20178101 We have recently proposed that the progression or regression of a tumor lesion in cancer patients undergoing immunotherapy could be predetermined by the molecular mechanism responsible for the MHC Class I alteration and not by the type of immunotherapy used, i.e., interleukin-2 (IL-2), Bacillus Calmette-Guèrin (BCG), interferon-alpha (IFN-alpha), peptides alone, dendritic cells loaded with peptides, protein-bound polysaccharide etc.
7593 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.
7594 20219874 Following short-term stimulation with C. pneumoniae, both gamma interferon (IFN-gamma)- and interleukin-2 (IL-2)-producing CD4(+) T-cell responses could be detected in 16 of 56 healthy individuals.
7595 20219874 C. pneumoniae-activated CD4(+) T cells expressed CD154, a marker for T-cell receptor-dependent activation, and displayed a phenotype of central memory T cells showing dominant IL-2 production but also IFN-gamma production.
7596 20219874 Interestingly, individuals with both IFN-gamma- and IL-2-producing responses showed significantly decreased immunoglobulin G reactivity toward C. pneumoniae RpoA and DnaK, antigens known to be strongly upregulated during chlamydial persistence, compared to IgG reactivity of seropositive individuals with no T-cell response or CD4(+) T-cell responses involving the production of a single cytokine (IFN-gamma or IL-2).
7597 20219874 Furthermore, among seropositive individuals, the presence or the absence of dual IFN-gamma- and IL-2-producing T-cell responses was associated with distinct patterns of antibody responses toward persistence-associated C. pneumoniae antigens.

7600 20219874 Interestingly, individuals with both IFN-gamma- and IL-2-producing responses showed significantly decreased immunoglobulin G reactivity toward C. pneumoniae RpoA and DnaK, antigens known to be strongly upregulated during chlamydial persistence, compared to IgG reactivity of seropositive individuals with no T-cell response or CD4(+) T-cell responses involving the production of a single cytokine (IFN-gamma or IL-2).
7601 20219874 Furthermore, among seropositive individuals, the presence or the absence of dual IFN-gamma- and IL-2-producing T-cell responses was associated with distinct patterns of antibody responses toward persistence-associated C. pneumoniae antigens.

7604 20219874 Interestingly, individuals with both IFN-gamma- and IL-2-producing responses showed significantly decreased immunoglobulin G reactivity toward C. pneumoniae RpoA and DnaK, antigens known to be strongly upregulated during chlamydial persistence, compared to IgG reactivity of seropositive individuals with no T-cell response or CD4(+) T-cell responses involving the production of a single cytokine (IFN-gamma or IL-2).
7605 20219874 Furthermore, among seropositive individuals, the presence or the absence of dual IFN-gamma- and IL-2-producing T-cell responses was associated with distinct patterns of antibody responses toward persistence-associated C. pneumoniae antigens.
7606 20219874 Following short-term stimulation with C. pneumoniae, both gamma interferon (IFN-gamma)- and interleukin-2 (IL-2)-producing CD4(+) T-cell responses could be detected in 16 of 56 healthy individuals.
7607 20219874 C. pneumoniae-activated CD4(+) T cells expressed CD154, a marker for T-cell receptor-dependent activation, and displayed a phenotype of central memory T cells showing dominant IL-2 production but also IFN-gamma production.

7609 20219874 Furthermore, among seropositive individuals, the presence or the absence of dual IFN-gamma- and IL-2-producing T-cell responses was associated with distinct patterns of antibody responses toward persistence-associated C. pneumoniae antigens.
7610 20219877 Furthermore, the immunization of mice with gamma-PGA NPs carrying ovalbumin (OVA) as an antigen significantly induced antigen-specific CD8(+) T cells and antigen-specific production of interleukin-2, tumor necrosis factor alpha, and gamma interferon from the cells.
7611 20224419 Whole Peripheral blood mononuclear cells or CD8(+) cell-depleted peripheral blood mononuclear cells from previously tetanus toxoid (TT)-immunized individuals were activated with TT plus IL-2, and cell proliferation, cytokine production, and in vitro HIV-1 replication were measured.
7612 20224419 Although the IL-1beta and tumour necrosis factor alpha (TNF-alpha) production were higher in cultures from aged HIV-1-infected patients, a dramatic damage on the interferon gamma (IFN-gamma) release was observed, when compared with younger patients.
7613 20224419 CD8(+) T lymphocytes depletion reduced IL-1beta and TNF-alpha release in the older groups, however, it did not significantly alter their IFN-gamma production.
7614 20224419 Furthermore, the neutralization of endogenous IL-10 did not change the IFN-gamma deficiency in older AIDS patients.
7615 20309907 In the CD8(+) compartment, the release of IFN and IFN-inducers leads to the production of IL-15, which mediates the proliferation of CD8(+) T cells, notably memory-phenotype CD8(+) T cells.
7616 20309907 A study in this issue of the European Journal of Immunology sheds light on this aspect, suggesting that common gamma-chain cytokines including IL-2 might be involved in bystander activation of CD4(+) T cells.
7617 20336365 Both CD4(+) and CD8(+) p53-specific T cells secreted IFN-γ after stimulation with p53-transfected DCs.
7618 20336365 Furthermore, significantly higher secretion of IL-2 was detected in peripheral blood mononuclear cells after stimulation with p53-transfected DCs from patients with p53(high) tumor expression compared to patients with p53(low) tumor expression, whereas secretion of IL-10 was predominant in the latter group.

7620 20347492 Both swine and bovine CXCL11 were chemotactic for mitogen and IL-2 stimulated peripheral blood mononuclear cells.
7621 20357059 In this study, we assessed the immunizing activity of a recombinant modified vaccinia Ankara (MVA) construct (MVA/IL-15/5Mtb) which overexpresses five Mycobacterium tuberculosis antigens (antigen 85A, antigen 85B, ESAT6, HSP60, and Mtb39), as well as the molecular adjuvant interleukin-15 (IL-15).
7622 20357059 At 16 months, when the Mycobacterium bovis BCG and MVA/IL-15/5Mtb vaccine-induced protection was essentially equivalent, the protective responses after a tuberculous challenge were associated with elevated levels of gamma interferon (IFN-gamma), IL-17F, Cxcl9, and Cxcl10.
7623 20357059 Long-term memory after immunization with the E6-85-MVA/IL-15/5Mtb combination regimen was associated with the induction of monofunctional CD4 and CD8 IFN-gamma-producing T cells and multifunctional CD4 and CD8 T cells expressing IFN-gamma/tumor necrosis factor alpha (TNF-alpha), TNF-alpha/IL-2, and IFN-gamma/TNF-alpha/IL-2.
7624 20357059 In contrast, BCG-induced protection was characterized by fewer CD4 and CD8 monofunctional T cells expressing IFN-gamma and only IFN-gamma/TNF-alpha and IFN-gamma/TNF-alpha/IL-2 expressing multifunctional T (MFT) cells.

7630 20362206 The preS2 epitope favored a well-balanced response with CD4+ and CD8+ T cells producing IFN-gamma, IL-2 and TNF-alpha.
7631 20382274 Spleen cells from G22-I50-immunized mice gave a significant proliferative response and higher expression level of IFN-gamma and IL-2.These results suggested that bispecific anti-Id antibody vaccine was able to induce more powerful humoral and cell-mediated immune responses, which might make it to be a potential vaccine candidate for the therapy of nasopharyngeal carcinoma.
7632 20386085 Immature DCs were mature with NK cells in the presence of lipopolysaccharide, which is TLR4 agonist, and further addition of IL-2 induced phenotypically and functionally mature bone marrow-derived DCs.

7649 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.
7650 20394723 Moreover, PTD-HBcAg fusion protein increased significantly the percentages of IFN-gamma+CD8+ T cells and HBcAg-specific (CTL) responses.
7651 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.
7652 20414189 Here, we describe a method for the detailed phenotypic and functional analyses of cellular immune responses, specifically intracellular cytokine production by CD4+ and CD8+ T cells as well as the individual memory subsets.
7653 20414189 We obtained precise quantitative and qualitative measures for the production of interferon gamma (INF-) and interleukin (IL) -2 in both CD4+ and CD8+ T cells from the rhesus macaque PBMC stimulated with PMA plus ionomycin (PMA+I).
7654 20414189 Furthermore, this protocol provided us the sensitivity to demonstrate even minor fractions of antigen specific CD4+ and CD8+ T cell subsets within the PBMC samples from rhesus macaques immunized with an HIV envelope peptide cocktail vaccine developed in our laboratory.
7655 20427628 We found that only interleukin 12 (IL-12), not other costimulants, increased IFN-gamma production in WBA while maintaining M. leprae peptide specificity, as evidenced by lack of increase of IFN-gamma in control samples stimulated with IL-12 alone.
7656 20427628 The IL-12-induced increase in IFN-gamma was mainly mediated by CD4+ T cells that did not produce IL-2 or tumor necrosis factor (TNF).
7657 20427628 Although not statistically significantly, macrophage inflammatory protein 1beta (MIP-1beta) and macrophage c protein 1 (MCP-1) levels specific for M. leprae peptide tended to be increased by IL-12.
7658 20427628 IP-10 production was also found to be a useful marker of M. leprae peptide responses, but its production was enhanced by IL-12 nonspecifically.
7659 20435929 Polyfunctional CD4(+) and CD8(+) T cell responses to tuberculosis antigens in HIV-1-infected patients before and after anti-retroviral treatment.
7660 20435929 We assessed polyfunctional (IFN-gamma(+)IL-2(+)TNF-alpha(+)) T cell responses to TB Ags in three groups of HIV-1-infected patients dependent on their TB status, CD4 counts, and anti-retroviral exposure.
7661 20435929 We found that although the proportion of IFN-gamma cells in response to TB Ags was higher in patients with low CD4 counts, the responding cells changed from a polyfunctional CD4(+) to a monofunctional CD8(+) response.
7662 20435931 Knockdown of CD40, CD80, and CD86, prior to loading DCs with the arthritogenic Ag collagen II, led to a population of cells that could effectively suppress onset of collagen-induced arthritis.
7663 20435931 Disease suppression was associated with inhibition of collagen II-specific Ab production and suppression of T cell recall responses.
7664 20435931 Downregulation of IL-2, IFN-gamma, TNF-alpha, and IL-17 and increased FoxP3(+) cells with regulatory activity were observed in collagen-induced arthritis mice treated with siRNA-transfected DCs.
7665 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.
7666 20451637 A single immunization of naïve mice with recombinant YF17D resulted in robust production of IFN-gamma by CD8(+) T-cells and IFN-gamma and IL-2 by CD4(+) T-cells.
7667 20471443 Incorporation of CD40 ligand into SHIV virus-like particles (VLP) enhances SHIV-VLP-induced dendritic cell activation and boosts immune responses against HIV.
7668 20471443 Engagement of CD40 with CD40L induces dendritic cell (DC) maturation and activation, thereby promoting immune responses.
7669 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.
7670 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.
7671 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.
7672 20471443 Therefore, incorporation of CD40L into VLP may represent a novel strategy to develop effective HIV vaccines.
7673 20480224 CD4+ T cells inhibit the neu-specific CD8+ T-cell exhaustion during the priming phase of immune responses against breast cancer.
7674 20480224 Studies conducted in animal model of infectious diseases or H-Y antigen model suggest a crucial role for CD4+ T cells in providing help for CD8+ T-cell memory responses.
7675 20480224 Although this concept has been applied to cancer vaccine design, the role of CD4+ T cells in the memory differentiation of CD8+ T cells and retention of their anti-tumor function have never been tested in breast cancer model.
7676 20480224 Such differential effects, in vivo, were associated with higher frequency of CD8+PD-L1+ and CD8+PD-1+ T cells in animals harboring helpless T cells as well as higher titer of IL-2 in the sera of animals harboring helped T cells.
7677 20480224 However, depletion of CD4+ T cells did not alter the ability of neu-specific CD8+ T cells to differentiate into memory cells and to retain their effector function against the tumor during recall challenge.
7678 20480224 These results suggest the inhibitory role of CD4+ T cells on CD8+ T-cell exhaustion without substantial effects on the differentiation of memory T cells during priming phase of the immune responses against breast cancer.
7679 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.
7680 20483237 Pro-inflammatory cytokines like TNF's, IL-6 and IL-17 family have been cloned.
7681 20483237 Among the T(H)1 type interleukins, IL-2, IL-15, IL-12alpha, IL-12beta, IL-18 have been cloned.
7682 20483237 Among IL-10 and its family members, IL-10, IL-19/20, IL-22 and IL-26 have been discovered.
7683 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.
7684 20508727 In addition, IDLV immunization induced high frequency of polyfunctional CD8+ T cells able to simultaneously produce IFNgamma, TNFalpha, and IL2.
7685 20518579 The phase II studies demonstrated the potential utility of continuous intravenous IL-2 and subsequently intermittent dosing with subcutaneous rIL-2 as a cytokine that could expand the CD4+ T-cell pool in HIV-1-infected patients without any significant detrimental effect on HIV viral load and with an acceptable adverse-effect profile.
7686 20519649 The CD8(+) T cell response to infection is characterized by the appearance of short-lived (CD127(low) killer cell lectin-like receptor G 1-high) and memory-precursor (CD127(high) killer cell lectin-like receptor G 1-low) effector cells.
7687 20519649 Furthermore, the extent of early Ag availability, which regulated programmed death-1 and CD25 expression levels, controlled the T(CM)/T(EM) cell lineage decision ultimately through IL-2 and IL-15 signaling levels.
7688 20530206 Using two distinct vaccine platforms, we evaluate the influence of interleukin (IL) 10 production on the magnitude, quality, and protective capacity of CD4(+) T cell responses in the mouse model of Leishmania major infection.
7689 20530206 Multiparameter flow cytometry was used to delineate the CD4(+) T cell production of interferon (IFN) gamma, IL-2, tumor necrosis factor (TNF), and IL-10 (or combinations thereof) after vaccination.
7690 20530206 Immunization with a high dose of adenovirus (ADV) expressing leishmanial proteins (MML-ADV) elicited a limited proportion of multifunctional IFN-gamma(+)IL-2(+)TNF(+) Th1 cells, a high frequency of IL-10-producing CD4(+) T cells, and did not protect against subsequent challenge.
7691 20530206 In contrast, after immunization with MML protein and CpG (MML + CpG), IL-10 limited the production of IL-12 by DCs in vivo, thereby decreasing the generation of multifunctional Th1 cells.
7692 20530206 Using two distinct vaccine platforms, we evaluate the influence of interleukin (IL) 10 production on the magnitude, quality, and protective capacity of CD4(+) T cell responses in the mouse model of Leishmania major infection.
7693 20530206 Multiparameter flow cytometry was used to delineate the CD4(+) T cell production of interferon (IFN) gamma, IL-2, tumor necrosis factor (TNF), and IL-10 (or combinations thereof) after vaccination.
7694 20530206 Immunization with a high dose of adenovirus (ADV) expressing leishmanial proteins (MML-ADV) elicited a limited proportion of multifunctional IFN-gamma(+)IL-2(+)TNF(+) Th1 cells, a high frequency of IL-10-producing CD4(+) T cells, and did not protect against subsequent challenge.
7695 20530206 In contrast, after immunization with MML protein and CpG (MML + CpG), IL-10 limited the production of IL-12 by DCs in vivo, thereby decreasing the generation of multifunctional Th1 cells.
7696 20535218 By means of short-term polychromatic intracellular cytokine staining, we observed a significant increase in polyfunctional Nef-specific CD4 T cells expressing interferon-γ, interleukin (IL)-2 and CD154 after vaccination, whereas changes in the quality of CD8 T-cell response could not be observed.
7697 20535218 Only the additional use of a long-term polychromatic Carboxyfluorescein succinimidyl ester (CFSE)-based proliferation assay revealed vaccine-induced Nef-specific CD8, as well as CD4 T cells with proliferative capacity.
7698 20535218 The correlation between vaccine-induced IL-2 production by CD4 T cells and the increase in proliferating Nef-specific CD8 T cells suggests a causal link between these two functions.
7699 20535218 By means of short-term polychromatic intracellular cytokine staining, we observed a significant increase in polyfunctional Nef-specific CD4 T cells expressing interferon-γ, interleukin (IL)-2 and CD154 after vaccination, whereas changes in the quality of CD8 T-cell response could not be observed.
7700 20535218 Only the additional use of a long-term polychromatic Carboxyfluorescein succinimidyl ester (CFSE)-based proliferation assay revealed vaccine-induced Nef-specific CD8, as well as CD4 T cells with proliferative capacity.
7701 20535218 The correlation between vaccine-induced IL-2 production by CD4 T cells and the increase in proliferating Nef-specific CD8 T cells suggests a causal link between these two functions.
7702 20541870 Increased levels of gene transcripts encoding IL-2, IL-10, IL-17A, and IFN-gamma, but decreased levels of IL-15 mRNAs, were seen in intestinal intraepithelial lymphocytes of chickens immunized with profilin plus adjuvants compared with immunization with profilin alone.
7703 20557286 Delivery of a plasmid DNA encoding interleukin-12 (IL-12) or interleukin-2 (IL-2) using electroporation was demonstrated to be a safe with no grade 3 or 4 toxicities reported.
7704 20561603 All mice vaccinated with recombinant virus developed specific anti-SWAP (soluble worm antigen preparation) antibody, splenocyte proliferative response and production of IFN-gamma and IL-2.
7705 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.
7706 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.
7707 20582165 Here, using an in vitro system where activated CD8 T cells driven by IL-2 or IL-15 become either effector memory or central memory cells, we assessed the role of microRNAs in memory T cell fate determination.
7708 20582165 We found that fate determination to central memory T cells is under the balancing effects of a discrete number of microRNAs including miR-150, miR-155 and the let-7 family.
7709 20582165 Based on miR-150 a new target, KChIP.1 (K (+) channel interacting protein 1), was uncovered, which is specifically upregulated in developing central memory CD8 T cells.
7710 20586188 Triple immunization of mice with the plasmid vaccine induced a pronounced cellular immune response against abroad spectrum of NSSA epitopes as assessed by T-cell proliferation andsecretion of antiviral cytokines IFN-gamma and IL-2.
7711 20600494 A test antigen, HIV-1 p24 (clade B consensus), was inserted near the 5' end of YF17D, in frame and upstream of the polyprotein (YF-5'/p24), or between the envelope and the first non-structural protein (YF-E/p24/NS1).
7712 20600494 In vitro characterization of these recombinants indicated that the gene insert was more stable in the context of YF-E/p24/NS1.
7713 20600494 CD8(+) IFN-gamma T-cell responses against p24 were elicited by the YF17D recombinants, as were specific CD4(+) T cells expressing IFN-gamma and IL-2.
7714 20600494 A balanced CD4(+) and CD8(+) T-cell response was notable, as was the polyfunctionality of the responding cells.
7715 20600494 Finally, the protective efficacy of the YF17D recombinants, particularly YF-E/p24/NS1, in mice challenged with a vaccinia expressing HIV-1 Gag was demonstrated.
7716 20625487 Fifty six genes such as TNF, NFKB1, IL2, IL6, and MAPK8 were ranked among the top 25 by at least one of the centrality methods in one or both networks.
7717 20631337 Using 5 HIV-1 antigens as stimulants, we assessed lymphocyte proliferation, supernatant gamma interferon (IFN-gamma) cytokine production (CP), single-cell IFN-gamma production by enzyme-linked immunospot (ELISPOT) assay, with and without Epstein-Barr virus-transformed B-lymphoblastoid cell lines (B-LCLs), and intracellular cytokine production (ICC) for IFN-gamma and interleukin 2 (IL-2) by flow cytometry.
7718 20635977 Immunotherapeutic approaches with IL-2 and/or IFN-alpha have become standard regimens in treating metastatic renal cell cancer.
7719 20647327 Tumor-specific CD8+ T cells expressing interleukin-12 eradicate established cancers in lymphodepleted hosts.
7720 20647327 In this study, we report that approximately 10,000 T cells gene-engineered to express a single-chain IL-12 molecule can be therapeutically effective against established tumors in the absence of exogenous IL-2 and vaccine.
7721 20647327 Successful tumor eradication was dependent on a lymphodepleting preconditioning regimen that reduced the number of intratumoral CD4(+) Foxp3(+) T regulatory cells.
7722 20660136 Because of the potential importance of HLA-E-restricted CD8(+) responses in resistance to Salmonella infection, we characterized these responses and investigated their kinetics of appearance and persistence in volunteers immunized orally with the licensed attenuated Ty21a strain typhoid vaccine.
7723 20660136 An ex vivo multicolor staining panel including antibodies to CD107a and -b, interleukin-2, gamma interferon (IFN-gamma), and tumor necrosis factor alpha (TNF-alpha) was used to functionally assess memory T-cell subsets by flow cytometry.
7724 20660136 The majority of HLA-E-restricted CD8(+) cells 28 to 56 days after immunization coexpressed CD107, IFN-gamma, and TNF-alpha, showing characteristic features of multifunctional T cells.
7725 20660136 In summary, the multifunctionality and longevity of the HLA-E-restricted CD8 responses observed in this study highlight their significance in adaptive immunity to S.
7726 20660136 Finally, this is the first demonstration, in either animals or humans, of the presence of long-term multifunctional HLA-E-restricted CD8(+) cells after immunization.
7727 20664359 In an attempt to improve persistence of the transferred lymphocytes, we cotransduced human peripheral blood lymphocytes with retroviruses encoding Bcl-2 or Bcl-xL, antiapoptotic genes of the BCL2 family, and the MART-1 melanoma tumor antigen-specific TCR, DMF5.
7728 20664359 Cotransduction with Bcl-2 or Bcl-xL did not affect cytokine secretion or lytic ability of the DMF5-transduced lymphocytes.
7729 20664359 Thus, by coexpressing Bcl-2 or Bcl-xL with a tumor-specific TCR, we have engineered a lymphocyte that resists apoptosis owing to IL-2 withdrawal without altering its tumor-specific function or phenotype, and thus may show improved antitumor effectiveness in vivo after cell transfer.
7730 20668230 When mAb heavy chain was engineered to express HIV Gag p24, the fusion mAb induced interferon-γ- and interleukin-2-producing CD4(+) T cells in hDEC205 transgenic mice, if polynocinic polycytidylic acid was coadministered as an adjuvant.
7731 20679529 This "recall" NK cell response was absolutely dependent on Ag-specific IL-2 from CD45RO(+) CD4(+) T cells as well as IL-12 and IL-18 from accessory cells.
7732 20686664 Our results indicate that both the HCV TCR-transduced CD4(+) and CD8(+) T cells recognized the HCV NS3:1073-1081 peptide-loaded targets and HCV(+) hepatocellular carcinoma cells (HCC) in a polyfunctional manner with cytokine (IFN-gamma, IL-2, and TNF-alpha) production as well as cytotoxicity.
7733 20686664 Tumor cell recognition by HCV TCR transduced CD8(-) Jurkat cells and CD4(+) PBL-derived T cells indicated this TCR was CD8-independent, a property consistent with other high affinity TCRs.
7734 20709007 CD8+ T cell response in HLA-A*0201 transgenic mice is elicited by epitopes from SARS-CoV S protein.
7735 20709007 Results showed that peptide-specific CD8(+) T cells secreted IFN-γ, TNF-α and IL-2 and expressed CD107a/b on cell surface.
7736 20709007 IFN-γ(+)CD8(+) T cells and CD107a/b(+)CD8(+) T cells distributed throughout the lymphoid and non-lymphoid tissues, but the frequency of peptide-specific CD8(+) T cells was higher in lungs than in spleens and lymph nodes.
7737 20709007 Most of the HLA-A*0201 restricted peptide-specific CD8(+) T cells represented a memory subset with CD45RB(high) and CD62L(low).
7738 20709007 Taken together, these data demonstrate that immunization with SARS S DNA and HLA-A*0201 restricted peptides can elicit antigen-specific CD8(+) T cell immune responses which may have a significant implication in the long-term protection.
7739 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.
7740 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.
7741 20709527 CA9 is not expressed in healthy renal tissue but is expressed in most clear cell renal cell carcinomas (CCRCC) through HIF-1α accumulation driven by hypoxia and inactivation of the VHL gene.
7742 20709527 In metastatic disease, high CA9 expression by IHC was reported to be a powerful prognostic marker with better survival and sensitivity to IL-2, but this is still debated.
7743 20709527 The prognostic value of CA9 in CCRCC could be explained by the frequent VHL gene inactivation driving an early activation of the HIF pathway.
7744 20709527 The poorer prognosis associated with low CA9 expressing tumours could be due to the simultaneous overexpression of EGFR contributing to the activation of AkT and mTOR pathways.
7745 20719708 Recent data also suggest that IL-15 acts, not only on CD8+ T cells and natural killer cells, but also on effector memory CD4+ T cells.
7746 20719708 IL-15 clearly expands very different CD4+ T cell subpopulations than IL-2 in SIV-infected animals, and may be useful for the restoration of effector memory CD4+ T cells that are depleted early in HIV and SIV infection.
7747 20719985 These new HHV-8 epitopes activated monofunctional and polyfunctional CD8(+) T cells that produced various combinations of gamma interferon, interleukin 2, tumor necrosis factor alpha, macrophage inhibitory protein 1β, and cytotoxic degranulation marker CD107a in healthy HHV-8-seropositive individuals.
7748 20719985 We were also able to detect HHV-8-specific CD8(+) T cells in peripheral blood samples using HLA A*0201 pentamer complexes for one gB epitope, one K8.1 epitope, two LANA-1 epitopes, and one K12 epitope.
7749 20725863 The P38 and ERK Mitogen-Activated Protein Kinase (MAPK) pathways govern the regulation of cytokines (IL-2, IL-10, and TNF-α) as well biomarkers (PD-1, Fas/FasL, among others) that are skewed in chronic HIV infection.
7750 20725863 HIV utilizes the P38 and ERK pathways to produce new virions and to deplete CD4+ T cells from the host's immune system.
7751 20728522 All vaccine formulations induced strong HIV-specific CD4(+) T-cell responses characterized by high lymphoproliferative capacity and IL-2 production that were still detectable 18 months after last immunization, with strongest responses seen in the AS01(B) group.
7752 20733200 An attractive treatment of cancer consists in inducing tumor-eradicating CD8(+) CTL specific for tumor-associated Ags, such as NY-ESO-1 (ESO), a strongly immunogenic cancer germ line gene-encoded tumor-associated Ag, widely expressed on diverse tumors.
7753 20733200 This prime boost regimen was superior to other vaccine regimes and required strong Th1 cell responses, copresentation of MHC class I and MHC class II peptides by the same DC, and resulted in upregulation of sphingosine 1-phosphate receptor 1, and thus egress of freshly primed CD8(+) T cells from the draining lymph nodes into circulation.
7754 20733200 This well-defined system allowed detailed mechanistic analysis, which revealed that 1) the Th1 cytokines IFN-gamma and IL-2 played key roles in CTL priming, namely by upregulating on naive CD8(+) T cells the chemokine receptor CCR5; 2) the inflammatory chemokines CCL4 (MIP-1beta) and CCL3 (MIP-1alpha) chemoattracted primed CD4(+) T cells to mature DCs and activated, naive CD8(+) T cells to DC-CD4 conjugates, respectively; and 3) blockade of these chemokines or their common receptor CCR5 ablated priming of CD8(+) T cells and upregulation of sphingosine 1-phosphate receptor 1.
7755 20805358 Regulation of memory CD8 T-cell differentiation by cyclin-dependent kinase inhibitor p27Kip1.
7756 20805358 Here, we have identified the cyclin-dependent kinase inhibitor p27(Kip1) as a critical regulator of the CD8 T-cell homeostasis at all phases of the T-cell response to an acute viral infection in mice.
7757 20805358 By acting as a timer for cell cycle exit, p27(Kip1) curtailed the programmed expansion of interleukin-2-producing memory precursors and markedly limited the magnitude and quality of CD8 T-cell memory.
7758 20805358 In the absence of p27(Kip1), CD8 T cells showed superior recall responses shortly after vaccination with recombinant Listeria monocytogenes.
7759 20805358 Additionally, we show that p27(Kip1) constrains proliferative renewal of memory CD8 T cells, especially of the effector memory subset.
7760 20805358 These findings provide critical insights into the cell cycle regulation of CD8 T-cell homeostasis and suggest that modulation of p27(Kip1) could bolster vaccine-induced T-cell memory and protective immunity.
7761 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.
7762 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.
7763 20816019 Patients with progressive disease had increasing levels of CEA and TIMP-1, while patients achieving stable disease maintained relatively stable levels.
7764 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.
7765 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.
7766 20816019 Patients with progressive disease had increasing levels of CEA and TIMP-1, while patients achieving stable disease maintained relatively stable levels.
7767 20829398 The ratios of CD4(+) to CD8(+) T lymphocytes in chickens immunized with pgB plus pIL-18 were significantly higher than in those immunized with pgB alone.
7768 20829398 Co-injection of pIL-18 significantly increased the production of gamma interferon and IL-2, indicating that IL-18 enhances the T helper 1-dominant immune response.
7769 20851080 Furthermore, intracellular cytokine staining showed an increase in the proportion of memory LEISH-F1-specific IL-2(+) CD4 T-cells after vaccination, which was associated with clinical cure.
7770 20863822 There was statistically significant upregulation of costimulatory molecules and maturation markers (CD86, CD83, CD80 and CL II) in DC loaded with cryotreated whole tumour cells compared to both control DC and DC matured with LPS (P < 0.001).
7771 20863822 There was a significant increase in stimulatory cytokines gene expression (IL-2, IL-12, IL-15, IL-18 and IFN-γ).
7772 20863822 The effect of different freezing temperature was equal. cDNA microarray analysis showed upregulation of interleukin 1 (IL-1) and cycline dependent kinase inhibitor 1A (CDKN1A (p21) and downregulation of Caspase 8 and BCL2.
7773 20870934 CD4+ T cells are not required for the induction of dengue virus-specific CD8+ T cell or antibody responses but contribute to protection after vaccination.
7774 20870934 The DENV-specific CD4(+) T cells expressed intracellular IFN-γ, TNF, IL-2, and CD40L, and killed peptide-pulsed target cells in vivo.
7775 20870934 Consistent with this observation, CD4(+) T cell depletion did not affect the DENV-specific IgG or IgM Ab titers or their neutralizing activity, or the DENV-specific CD8(+) T cell response.
7776 20887831 To augment their immunogenic properties, the fibroblasts were genetically modified before Trop-1 DNA-transfer to secrete IL-2 and to express allogeneic MHC class I H-2K(b)-determinants.
7777 20887831 Mice with established breast cancer treated solely by immunization with fibroblasts modified to express Trop-1 developed CD8(+) cell-mediated immunity to the breast cancer cells.
7778 20944089 In mice, this fusion protein-adjuvant combination induced polyfunctional CD4 T helper 1 cell responses characterized by antigen-specific interferon-γ, tumor necrosis factor, and interleukin-2, as well as a reduction in the number of bacteria in the lungs of animals after they were subsequently infected with virulent or multidrug-resistant Mtb strains.

7780 20963411 Pitfalls of vaccinations with WT1-, Proteinase3- and MUC1-derived peptides in combination with MontanideISA51 and CpG7909.
7781 20963411 T cells with specificity for antigens derived from Wilms Tumor gene (WT1), Proteinase3 (Pr3), and mucin1 (MUC1) have been demonstrated to lyse acute myeloid leukemia (AML) blasts and multiple-myeloma (MM) cells, and strategies to enhance or induce such tumor-specific T cells by vaccination are currently being explored in multiple clinical trials.
7782 20963411 To test safety and immunogenicity of a vaccine composed of WT1-, Pr3-, and MUC1-derived Class I-restricted peptides and the pan HLA-DR T helper cell epitope (PADRE) or MUC1-helper epitopes in combination with CpG7909 and MontanideISA51, four patients with AML and five with MM were repetitively vaccinated.
7783 20963411 Neither pre-existing nor naive WT1-/Pr3-/MUC1-specific CD8+ T cells expanded in vivo by vaccination.
7784 20963411 An increase in PADRE-specific CD4+ T helper cells was observed after vaccination but these appeared unable to produce IL2, and CD4+ T cells with a regulatory phenotype increased.
7785 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.
7786 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.
7787 21035507 In these cells CD4/CD8 derived IFN-γ release was also determined.
7788 21039735 The aim of this study was to clone these genes into DNA vaccine vectors capable of expressing them in eukaryotic cells as fusion proteins, fused with immunostimulatory signal peptides of human interleukin-2 (hIL-2) and tissue plasminogen activator (tPA), and evaluate the recombinant DNA vaccine constructs for induction of antigen-specific cellular immune responses in mice.
7789 21039735 DNA corresponding to the aforementioned RD1 and RD9 genes was cloned into DNA vaccine plasmid vectors pUMVC6 and pUMVC7 (with hIL-2 and tPA signal peptides, respectively), and a total of 10 recombinant DNA vaccine constructs were obtained.

7791 21039735 DNA corresponding to the aforementioned RD1 and RD9 genes was cloned into DNA vaccine plasmid vectors pUMVC6 and pUMVC7 (with hIL-2 and tPA signal peptides, respectively), and a total of 10 recombinant DNA vaccine constructs were obtained.
7792 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.
7793 21039737 There were no statistical changes for CD4/CD8 ratios, IL-4 and CD69 levels between the three-vaccine immunized groups.
7794 21042712 Herein we describe T cell costimulation via CD25, the interleukin (IL)-2 receptor, during priming of naive T cells with a tumor vaccine.
7795 21042712 To this end, we produced, purified and characterized the fusion protein bsHN-IL2 which contains the IL-2 cytokine and an antibody scFv fragment directed towards the Hemagglutinin-Neuraminidase (HN) protein of Newcastle Disease Virus (NDV).
7796 21042712 In the presence of CD3-mediated signal 1, the vaccine/bsHN-IL2 provided via CD25 a strong bystander antitumor effect in vitro leading to tumor growth inhibition, even stronger than the vaccine/bsHN-CD28 which provides costimulation via CD28.
7797 21042712 Transcriptome analysis of naive T cells which were stimulated with the vaccine/bsHN-IL2 showed, similarly to the vaccine/bsHN-CD28, upregulation of 71 genes belonging to different signalling pathways, including PLC-γ1, Grb-2, Vav-1 and PDE-4A.

7806 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.
7807 21057930 However, the number of cells secreting TH2 cytokines IL-4 and IL-5 in hydrogen peroxide-treated group did not change.
7808 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.

7812 21060869 The GLA-SE adjuvanted Fluzone vaccine caused no adverse reactions, increased the induction of T helper type 1 (T(H)1)-biased cytokines such as IFNγ, TNF and IL-2, and broadened serological responses against drifted A/H1N1 and A/H3N2 influenza variants.
7813 21069322 This phase II study determined the efficacy and tolerability of TG4010, a cancer vaccine based on a modified vaccinia virus expressing MUC1 and interleukin-2, in combination with cytokines, as first-line therapy in metastatic RCC.
7814 21069322 Thirty-seven patients with progressive, MUC1-positive RCC received TG4010 10(8) pfu/inj weekly for 6 weeks, then every 3 weeks until progression, when TG4010 was continued in combination with interferon-α2a and interleukin-2.
7815 21069322 Six of 28 patients showed a MUC1 CD4+ T cell proliferative response during therapy.

7821 21074276 Regulation of IgA production in cattle is not completely understood and thus we have focused in part on highly conserved factors such as transforming growth factor beta, Type I and Type 2 interferons, neuropeptides which interdigitate mucosal tissues (vasoactive intestinal peptide or VIP), and a small peptide (IgA inducing peptide or IGIP) which can serve as targets for modulation and increasing SIgA virus-specific antibodies.
7822 21074276 In previous studies in cattle, IgA has been shown to be regulated by several cytokines including IFN-gamma, Type I interferons such as IFN-alpha and IFN-tau, transforming growth factor beta, IgA inducing peptide and other potential factors such as APRIL and BlyS which have not yet been fully evaluated in cattle.
7823 21074276 Many of these factors, namely TGF-beta and Type I interferons block cell cycle progression which is an essential component of Ig class switching and thus these factors require additional regulatory factors such as IL-2 to drive cells through cell cycle resulting in class switch recombination.
7824 21079516 We hypothesize that polyfunctional HIV-1-specific CD8 T cells capable of viral control are present in most patients early in infection and these cells are distinguished by their ability to secrete interleukin (IL)-2 and proliferate.
7825 21079516 We examined HIV-1-specific CD8 T-cell proliferation and cytokine secretion in primary HIV-1 infection (PHI) using known HIV-1 cytotoxic T-cell epitopes to exclude CD4 bystander effect.
7826 21079516 We found that only a subset of patients with PHI demonstrated "CD4-independent" CD8 proliferation ex vivo.
7827 21079516 The remainder of the patients lacked HIV-1-specific CD8 T cells with proliferative capacity, even after the addition of exogenous IL-2.
7828 21079516 Among the proliferators, IL-2 production from the total HIV-specific CD8 T-cell population correlated with proliferation.
7829 21079516 Surprisingly, though, we did not routinely detect both IL-2 secretion and proliferative capacity from the same antigen-specific CD8 T cells.
7830 21079516 Thus, there are distinct and heterogeneous populations of CD8 T cells, phenotypically characterized by either proliferation or IL-2 secretion and few with dual capacity.

7859 21095251 Secretion of IL-2, IL-6, IL-17, IFN-γ, and TNF-α was enhanced in cultures of AgI/II-stimulated splenic cells isolated from mice that had received LT-IIc as a mucosal adjuvant.
7860 21095251 In contrast to LT-IIa and LT-IIb, the original members of the type II subgroup that also are mucosal adjuvants, LT-IIc dramatically enhanced secretion of IL-1α and IL-1β in peritoneal macrophages that had been co-cultured with LPS.
7861 21095256 Evaluation of a DNA vaccine candidate expressing prM-E-NS1 antigens of dengue virus serotype 1 with or without granulocyte-macrophage colony-stimulating factor (GM-CSF) in immunogenicity and protection.
7862 21095256 In this study, we constructed DNA vaccines that carried the prM-E-NS1 genes of dengue virus serotype 1 (DV1) with or without the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene, an attractive DNA vaccine adjuvant.
7863 21095256 Immunization with the plasmid pCAG-DV1/E/NS1, which expresses viral prM-E-NS1, or the bicistronic plasmid pCAG-DV1-GM, which co-expresses viral prM-E-NS1 and GM-CSF, resulted in long-term IgG response, high levels of splenocyte-secreted interferon-γ and interleukin-2, strong cytotoxic T lymphocyte activity and sufficient protection in the DV1-challenged mice.
7864 21098256 The number of CD8(+) TCR Vβ families with clonal expansions at 12 weeks relative to baseline (median [10th to 90th percentile], +2.5 [0 to +7] versus +1 [0 to +2], P = 0.03) and at 24 weeks relative to 12 weeks (+1 [0 to +2] versus -1 [-3 to +4], P = 0.006) was higher in subjects with a virological response versus subjects without a virological response, as were interleukin-2 (IL-2) but not IL-21 mRNA levels in peripheral blood mononuclear cells.
7865 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.
7866 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.
7867 21169544 A total of 432 M. tuberculosis peptides predicted to bind to HLA-A*0201, HLA-A*0301, and HLA-B*0702 (representing the above supertypes) were synthesized and HLA-binding affinities determined.
7868 21169544 Using HLA/peptide tetramers for the 18 most prominently recognized HLA-A*0201-binding M. tuberculosis peptides, recognition by cured TB patients' CD8(+) T cells was validated for all 18 epitopes.
7869 21169544 Intracellular cytokine staining for IFN-γ, IL-2, and TNF-α revealed mono-, dual-, as well as triple-positive CD8(+) T cells, indicating these M. tuberculosis peptide-specific CD8(+) T cells were (poly)functional.
7870 21169544 Control CMV peptide/HLA-A*0201 tetramers stained CD8(+) T cells in M. tuberculosis-infected and noninfected individuals equally, whereas Ebola peptide/HLA-A*0201 tetramers were negative.
7871 21173782 Using Toll-like receptor (TLR) and MyD88 gene knock-out (GKO) mice the effect of TLRs and MyD88 on virus replication, interferon (IFN)-β production, natural killer (NK) cell and CD8T cell responses were assessed following ectromelia virus (ECTV) and recombinant vaccinia virus (rVV) infection.
7872 21173782 Results showed that TLR2(-/-), TLR4(-/-)and TLR7(-/-) mice survived ECTV infection whereas MyD88(-/-) and TLR9(-/-)mice, in contrast, were highly susceptible.
7873 21173782 Next, following infection with rVV, MyD88(-/-) mice elicited reduced serum IFN-β, NK cell and CD8T cell responses compared with wild-type mice, whereas TLR9(-/-) mice showed elevated CD8T cell responses.
7874 21173782 Interestingly, even though rVV co-expressing interleukin (IL)-2 enhanced NK cell activation in MyD88(-/-) mice, this was not associated with an antiviral effect, as observed in normal mice.
7875 21173782 Surprisingly, co-infection with rVV IL-2/rVV IL-12, but not rVV IL-2/rVV IFN-β, restored the attenuated phenotype of rVV IL-2 in MyD88(-/-) mice indicating that the IL-2/IL-12 combination promotes antiviral responses.
7876 21173782 Using Toll-like receptor (TLR) and MyD88 gene knock-out (GKO) mice the effect of TLRs and MyD88 on virus replication, interferon (IFN)-β production, natural killer (NK) cell and CD8T cell responses were assessed following ectromelia virus (ECTV) and recombinant vaccinia virus (rVV) infection.
7877 21173782 Results showed that TLR2(-/-), TLR4(-/-)and TLR7(-/-) mice survived ECTV infection whereas MyD88(-/-) and TLR9(-/-)mice, in contrast, were highly susceptible.
7878 21173782 Next, following infection with rVV, MyD88(-/-) mice elicited reduced serum IFN-β, NK cell and CD8T cell responses compared with wild-type mice, whereas TLR9(-/-) mice showed elevated CD8T cell responses.
7879 21173782 Interestingly, even though rVV co-expressing interleukin (IL)-2 enhanced NK cell activation in MyD88(-/-) mice, this was not associated with an antiviral effect, as observed in normal mice.
7880 21173782 Surprisingly, co-infection with rVV IL-2/rVV IL-12, but not rVV IL-2/rVV IFN-β, restored the attenuated phenotype of rVV IL-2 in MyD88(-/-) mice indicating that the IL-2/IL-12 combination promotes antiviral responses.
7881 21177920 Here, we investigated the protein levels of nuclear transcription factor NF-κB (p50, p65, and p105), IκBα (inhibitor of NF-κB), T-cell receptor (TCR) CD3ζ-chain, tyrosine kinase p56(LCK), and nuclear factor of activated T cells c2 (NF-ATc2) in peripheral blood CD4(+) T cells from patients with sarcoidosis.
7882 21177920 The reduced levels of p65 in sarcoid CD4(+) T cells concurred with decreased levels of p50, p105, CD3ζ, p56(LCK), IκBα, and NF-ATc2.
7883 21177920 Polyclonal stimulation of NF-κB-deficient sarcoid T cells resulted in reduced expression of CD69 and CD154, decreased proliferation, and cytokine (i.e., interleukin 2 [IL-2] and gamma interferon [IFN-γ]) production.
7884 21181148 The vaccinated groups also showed increased levels of Th1 cytokines interleukin (IL)-2, IL-12, and IFN-γ.
7885 21186260 Following tuberculin stimulation, activated CD4 T cells were identified by flow-cytometry (CD154 up-regulation, degranulation, interferon γ [IFN-γ], tumor necrosis factor α [TNF-α], and interleukin 2 [IL-2 production).
7886 21186260 Interestingly, CD154 up-regulation accounted for ∼80% of activated CD4 T cells in the active TB group but just 40% in the controls, whereas IFN-γ accounted for only ∼50% of activated cells in each group.
7887 21199392 For this purpose, serum concentration of interleukin 2 (IL2), interleukin 10 (IL10), interferon-gamma (IFNG), Toll-like receptor 2 (TLR2) and Toll-like receptor 9 (TLR9) were measured in blood samples obtained from F(2) piglets (n = 334) of a Duroc × Piétrain resource population (DUPI) after Mycoplasma hypopneumoniae (Mh), tetanus toxoid (TT) and Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) vaccination at 6, 9 and 15 weeks of age.
7888 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.
7889 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%).
7890 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.
7891 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%).
7892 21251901 The CCS lipid also increases production of cytokines (mainly IFN gamma, IL-2 and IL-12) and co-stimulatory molecules' expression, which might further explain the robust adjuvantation of this liposome-based vaccine.
7893 21257961 The AdIiNS3 vaccination induced polyfunctional CD8(+) T cells characterized by coproduction of IFN-γ, TNF-α and IL-2, and this cell phenotype is associated with good viral control.
7894 21257961 The memory CD8(+) T cells also expressed high levels of CD27 and CD127, which are markers of long-term survival and maintenance of T cell memory.
7895 21266849 Co-delivery of PSA and PSMA DNA vaccines with electroporation induces potent immune responses.
7896 21266849 We therefore developed highly optimized DNA vaccines encoding prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) as a dual antigen approach to immune therapy of PCa.
7897 21266849 Both the PSA and PSMA vaccines induced robust antigen-specific IFNγ responses by ELISpot.
7898 21266849 Further characterization of cellular immunogenicity by flow cytometry indicated strong antigen-specific TNFα production by CD4+ T cells and IFNγ and IL-2 secretion by both CD4+ and CD8+ T cells.
7899 21282337 Anti-IL-23 monoclonal antibody synergizes in combination with targeted therapies or IL-2 to suppress tumor growth and metastases.
7900 21282337 We have shown that host interleukin (IL)-23 suppresses the innate immune response during carcinogenesis and metastasis, independently of effects on the proinflammatory cytokine IL-17A.
7901 21282337 More notably, combinatorial treatments of anti-IL-23 mAb with IL-2 or anti-erbB2 mAb significantly inhibited subcutaneous growth of established mammary carcinomas and suppressed established experimental and spontaneous lung metastases.
7902 21282337 Overall, our results suggest the potential of anti-human IL-23 mAbs to improve the immunostimulatory effects of IL-2 and trastuzumab in the current management of some advanced human cancers.

7911 21291968 Specific cell-mediated immune responses such as lymphocyte transformation assay (stimulation-index) including release of interferon-gamma (IFN-γ), interleukin-2 (IL-2) and nitric-oxide were determined.
7912 21296978 We found that the frequency of multifunctional T cells coexpressing IFN-γ and TNF-α with or without IL-2 induced by live C. muridarum most accurately correlated with the pattern of protection against C. muridarum genital tract infection, suggesting that IFN-γ(+)-producing CD4(+) T cells that highly coexpress TNF-α may be the optimal effector cells for protective immunity.
7913 21300385 Eleven soft tissue- and five osteosarcoma canine patients were subjected to: (i) periodic subcutaneous injection of irradiated xenogeneic cells secreting hGM-CSF and hIL-2 mixed with allogeneic or autologous tumor homogenates; and (ii) injections of cIFN-β and HSVtk-carrying lipoplexes and ganciclovir, marginal (after surgery) and/or intratumoral (in the case of partial tumor resection, local relapse or small surface tumors).
7914 21314288 This antitumor immune effect of IR/DC was enhanced by pretreatment with CTX (CTX+IR/DC) and this effect was related with increased number of tumor-specific IFN-γ secreting T cells and decreased ratio of CD4(+)CD25(+)/CD4(+) T cells.
7915 21314288 The treatment with CTX+IR/DC increased or decreased the levels of IL-2 or IL-10, respectively.

7961 21351824 Both GNPs and AGNPs demonstrated comparable IgG response and a significantly higher (p < 0.05) cytokine response (IL-2 and IFN γ) as compared to alum-TT vaccine.
7962 21354949 The results show that cells stimulated to produce IFN-α and IFN-γ enter the circulating blood but those stimulated to produce IL-2 do not, or in very low number, and the IFN responses to both vaccines are the same.
7963 21364747 T cell depletion, T cell knockout and T cell adoptive transfer experiments suggest that both CD8(+) and CD4(+) T cells contribute to HSV-IL-2-induced CNS demyelination with CD8(+) T cells being the primary inducers.

7978 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.
7979 21408149 The vaccination also induces an increase in peripheral CD8(+)CD69(+) activated pertussis-specific memory T cells four weeks after vaccination.

8018 21424379 The major alleles of coding SNPs in the TLR2 (rs3804100) and TLR4 (rs5030710) genes were associated with a dose-related increase (660 vs. 892 mIU/ml, p = 0.002) and a dose-related decrease (2,209 vs. 830 mIU/ml, p = 0.001) in measles-specific antibodies, respectively.
8019 21424379 We observed an additional 12 associations (p < 0.01) between coding (nonsynonymous and synonymous) polymorphisms within the TLRs (TLR2, 7, and 8), IKBKE, TICAM1, NFKBIA, IRAK2, and KIAA1542 genes and variations in measles-specific IL-2, IL-6, IFN-α, IFN-γ, IFNλ-1, and TNF-α secretion levels.
8020 21427227 EspC contained broadly recognized CD4(+) and CD8(+) epitopes, inducing a predominantly CD4(+) T-cell response that comprised functional T-cell subsets secreting both IFN-γ and IL-2 as well as functional T-cell subsets secreting only IFN-γ.
8021 21439315 Extracellular vesicles purified from the Ag-pulsed DCs expressed surface proteins associated with DC-derived exosomes, including major histocompatibility complex proteins (MHC I and MHC II), CD80, flotillin, and heat shock protein (HSP70).
8022 21439315 Chickens immunized with pulsed DCs or exosomes exhibited (a) higher numbers of caecal tonsil and spleen cells expressing IgG and/or IgA antibodies that were reactive with E. tenella Ag, (b) greater numbers of IL-2-, IL-16-, and IFN-γ-producing cells, and (c) higher E. tenella Ag-driven cell proliferation, compared with chickens immunized with Ag in the absence of DCs or exosomes.
8023 21443961 The results were found that compared to those of the control piglets injected with VR1020-CNP, the content of IgG, IgA and IgM, specific antibodies, IL-2, IL-6 and IFN-γ significantly increased in the sera from the treated three groups from 14 to 70 days after vaccination (P<0.05); the number of T(H), T(C) and CD3(+) positive T cells raised obviously in the blood of VPIL6C treated piglets (P<0.05).
8024 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.
8025 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).
8026 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.
8027 21460206 Prolonged antitumor NK cell reactivity elicited by CXCL10-expressing dendritic cells licensed by CD40L+ CD4+ memory T cells.
8028 21460206 One month after DC immunization, injection of a tumor into DC-immunized mice leads to an increase in the expression of CXCL10 by endogenous DCs, thus directing NK cells into the white pulp where the endogenous DCs bridged CD4(+) T(EM) cells and NK cells.
8029 21460206 In this interaction, CD4(+) T(EM) cells express CD40L, which matures the endogenous DCs, and produce cytokines, such as IL-2, which activates NK cells.
8030 21467219 We compared in nonhuman primates (NHPs) immune responses to HIV Gag p24 within 3G9 antibody to DEC205 ("DEC-HIV Gag p24"), an uptake receptor on dendritic cells, to nontargeted protein, with or without poly ICLC, a synthetic double stranded RNA, as adjuvant.
8031 21467219 Priming s.c. with 60 μg of both HIV Gag p24 vaccines elicited potent CD4(+) T cells secreting IL-2, IFN-γ, and TNF-α, which also proliferated.
8032 21467219 DEC-HIV Gag p24 showed better cross-priming for CD8(+) T cells, whereas the avidity of anti-Gag antibodies was ∼10-fold higher with nontargeted Gag 24 protein.
8033 21467219 Gag-specific CD4(+) and CD8(+) T-cell responses increased markedly after priming with both protein vaccines and poly ICLC.
8034 21469087 CD38 identifies a hypo-proliferative IL-13-secreting CD4+ T-cell subset that does not fit into existing naive and memory phenotype paradigms.
8035 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.
8036 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.
8037 21469087 Instead, CD4(+) CD38(+) T cells expressed CD127, and hypo-proliferation was reversed by addition of IL-7, further associated with increased STAT5 phosphorylation.
8038 21469087 Activated CD4(+) CD38(+) cells had a bias towards IL-13 secretion, but not other Th2 cytokines such as IL-4 or IL-5.
8039 21469087 In comparison, the CD4(+) CD38(-) cells had a clear bias towards secretion of Th1-associated cytokines IFN-γ and TNF.
8040 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.
8041 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.

8079 21491085 In this study, we created a lentivirus expressing the AFP antigen and investigated the anti-tumor activity of AFP-specific CD8+ T cells, with and without CD4+ T cells, which were activated by either AFP peptide-pulsed or Lenti-AFP-engineered Dendritic cells (DCs) in vitro and in vivo.
8080 21491085 AFP-specific T cells could efficiently kill HepG2 HCC cells, and produced IL-2, IFN-γ, TNF-α, perforin and granzyme B, with minimal production of IL-10 (a negative regulator of T cell activation).
8081 21502499 Adenovirus type-35 vectors block human CD4+ T-cell activation via CD46 ligation.
8082 21502499 Whereas rAd5 binds coxsackie-adenovirus receptor (CAR), rAd35 binds the complement regulatory protein CD46.
8083 21502499 Although rAd35 infected and phenotypically matured human blood dendritic cells (DCs) more efficiently than rAd5, we show here that rAd35 markedly suppressed DC-induced activation of naive CD4(+) T cells. rAd35 specifically blocked both DCs and anti-CD3/CD28 mAb-induced naive T-cell proliferation and IL-2 production.
8084 21502499 Our findings provide insights into the basic biology of adenoviruses and indicate that CD46 binding may have an impact on the generation of primary CD4(+) T-cell responses by Ad35.

8128 21533229 At the peak response time point, PBMC from Ad5-seronegative vaccinees secreted significantly more IP-10 in response to Gag (p = 0.008), and significantly more IP-10 (p = 0.0009), IL-2 (p = 0.006) and IL-10 (p = 0.05) in response to Ad5 empty vector than PBMC from Ad5-seropositive vaccinees.
8129 21533229 Additionally, similar responses to the Ad5 vector prior to vaccination were observed in almost all subjects, regardless of Ad5 neutralizing antibody status, and the levels of secreted IFN-γ, IL-10, IL-1Ra and GM-CSF were blunted following vaccination.

8149 21533347 When the tumorigenicity of the clones carrying an inserted IL-2 gene was compared with that of the clones carrying an inserted CD80 gene, it was found that the insertion of the IL-2 gene suppresses tumorigenicity more efficiently than insertion of the CD80 gene.
8150 21533347 Admixture of the IL-2-producing MC12 clones to the tumorigenic CD80(+) MC12 cell doses could completely inhibit the tumorigenicity of the CD80(+) cells.
8151 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).
8152 21544385 IL-2 administration was found to be accompanied with an increase of TCR alpha beta(+), CD4(+) T cells in the spleen.
8153 21544385 Following the IL-2 treatment, the percentage of lymph node TCR alpha beta(+), CD4(+) and CD8(+) cells dropped to less than half of the pretreatment values and then again gradually increased.
8154 21544385 These results suggest that local administration of IL-2 at the site of vaccination elicits, in addition to the reaction in regional lymph nodes, a systemic reaction detectable in the spleen; they also suggest that the increase of CD4(+), TCR alpha beta(+) T splenocytes may play an important role in the mechanism of the observed adjuvant effect of IL-2.

8170 21565244 SL immunization promoted a mixed Th1/Th2 response, based on cytokine analysis (IL-2, IL-4, IL-10 and INFγ).
8171 21570434 PBLs obtained from 13 naïve donors all proliferated, with a Stimulation Index (SI≥2), to the MUC1-SP-L peptide, producing mixed CD4+ and CD8+ responses.
8172 21570434 CD4+ and CD8+ T cell populations exhibited CD45RO memory markers and secreted IFN-gamma and IL-2 following stimulation with MUC1-SP-L.
8173 21570434 Cytotoxicity to MUC1-expressing human and murine tumors was shown also in T cells obtained from HLA-A2 transgenic mice and BALB/c syngeneic mice immunized with the MUC1-SP-L and GM-CSF.

8175 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.
8176 21625608 Infection of MDDC with MVA-B or MVA, at the optimal dose of 0.3 PFU/MDDC, induced by itself a moderate degree of maturation of MDDC, involving secretion of cytokines and chemokines (IL1-ra, IL-7, TNF-α, IL-6, IL-12, IL-15, IL-8, MCP-1, MIP-1α, MIP-1β, RANTES, IP-10, MIG, and IFN-α).
8177 21625608 MDDC infected with MVA or MVA-B and following a period of 48 h or 72 h of maturation were able to migrate toward CCL19 or CCL21 chemokine gradients.
8178 21625608 MVA-B-infected MDDC co-cultured with autologous T lymphocytes induced a highly functional HIV-specific CD8(+) T cell response including proliferation, secretion of IFN-γ, IL-2, TNF-α, MIP-1β, MIP-1α, RANTES and IL-6, and strong cytotoxic activity against autologous HIV-1-infected CD4(+) T lymphocytes.
8179 21637109 Interleukin-2 production by polyfunctional HIV-1-specific CD8 T cells is associated with enhanced viral suppression.
8180 21690242 In addition, all groups generated a cellular immune response characterized by antigen-specific CD4(+) T cells secreting predominantly interleukin-2 (IL-2) and lesser amounts of tumor necrosis factor (TNF).

8211 21720558 These CD4+CD44(hi)CD62L(lo)CD27⁻ T cells concomitantly produce IFN-γ and TNF-α, or IFN-γ, IL-2 and TNF-α and have a higher cytokine median fluorescence intensity MFI or 'quality of response' than single cytokine producing cells.
8212 21722683 This study demonstrates that administration of trivalent influenza vaccine (TIV) with the cationic liposome adjuvant system CAF01 enhances the humoral immune response as measured by hemagglutinin inhibition titers and influenza-specific serum antibody titers, and promote a strong Th1 response with augmented levels of IL-1β, IL-2, IL-12, IFN-γ and TNF-α.
8213 21728003 For the F48E9 group, a sharp increase of the expression of interferon-alpha (IFN-α), interferon-gamma (IFN-γ), interleukin-16 and IL-18 was observed on 3 d.p.i. before the NDV blood peak (7 d.p.i.), followed by a rapid decline to the level lower than that of control group, then the expression of IFN-α increased slowly and reached or exceeded the level of control group in the later phase of the infection, while the expression of IFN-γ, IL-16, and IL-18 fluctuated at the level of control group for the rest of study period.
8214 21728003 The increase of IL-2 expression was not obvious, and no increase of IL-15 expression was noted.
8215 21728003 On the contrary, there was no dramatic increase of IL-16 and IL-18.
8216 21728172 Using multi-parameter flow cytometry and intracellular cytokine staining for IFN-γ, TNF-α and IL-2, we found double and single cytokine-producing CD4(+) as well as CD8(+) T cells to be the most prominent subsets, particularly IFN-γ(+) TNF-α(+) CD8(+) T cells.
8217 21728172 Furthermore, CFSE labeling revealed strong CD4(+) and CD8(+) T-cell proliferative responses induced by several "immunodominant" Mtb DosR antigens and their specific peptide epitopes.
8218 21728172 These findings demonstrate the prominent presence of double- and monofunctional CD4(+) and CD8(+) T-cell responses in naturally protected individuals and support the possibility of designing Mtb DosR antigen-based TB vaccines.
8219 21747747 CNP also significantly promoted the production of Th1 (IL-2 and IFN-γ) and Th2 (IL-10) cytokines and up-regulated the mRNA expression of IL-2, IFN-γ and IL-10 cytokines in splenocytes from the immunized mice compared with OVA and CS groups.
8220 21765018 We demonstrate that the size of the CD4(+) and CD8(+) CMV-specific T cell pools are similar in adult versus old RMs and show essentially identical phenotypic and functional characteristics, including a dominant effector memory phenotype, identical patterns of IFN-γ, TNF-α, and IL-2 production and cytotoxic degranulation, and comparable functional avidities of optimal epitope-specific CD8(+) T cells.

8251 21784871 Because immunosuppression continues to be a major inhibitor of cancer vaccine efficacy, we examined in this study whether therapeutically targeted delivery of a synthetic STAT-3 inhibitor to the TME, combined with an HER-2 DNA vaccine can improve immune surveillance against HER-2(+) breast cancer and prevent its recurrence.
8252 21784871 Furthermore, we showed that treatment with these NPs resulted in priming of the immune TME, characterized by increased IFN-γ, p-STAT-1, GM-CSF, IL-2, IL-15, and IL-12b and reduced TGF-β, IL-6, and IL-10 protein expression.
8253 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.
8254 21796616 However, synthetic T-cell vaccines composed of Melan-A/MART-1 peptide, CpG and IFA can induce high frequencies of tumor-specific CD8 T-cells in PBMC of melanoma patients.
8255 21796616 The production of multiple cytokines (IFNγ, TNFα, IL-2) and upregulation of LAMP-1 (CD107a) by tumor (Melan-A/MART-1) specific T-cells was comparable to virus (EBV-BMLF1) specific CD8 T-cells.
8256 21796616 Furthermore, phosphorylation of STAT1, STAT5 and ERK1/2, and expression of CD3 zeta chain were similar in tumor- and virus-specific T-cells, demonstrating functional signaling pathways.
8257 21802664 Synergy between TLR3 and IL-18 promotes IFN-γ dependent TRAIL expression in human liver NK cells.
8258 21802664 Our results show that the synthetic dsRNA polyinosinic-polycytidylic acid (poly I:C), a mimic of a common product of viral infections, activates NK cells directly in the context of cytokines found in the liver, i.e.: poly I:C plus inflammatory cytokines (IL-18, IL-12, and IL-2) induced NK cell IFN-γ production and TRAIL expression, and anti-inflammatory cytokines (TGF-β and IL-10) inhibit NK cell IFN-γ production.
8259 21822116 Serum cytokines [interleukin-2 (IL-2), IL-4, IL-6, interferon gamma, and tumor necrosis factor alpha] were assayed using standardized methodology.
8260 21849683 Regulatory T cells selectively control CD8+ T cell effector pool size via IL-2 restriction.
8261 21849683 Due to this change and the lower IL-2 production that results, a substantial fraction of CD8(+) effector T cells lose CD25 expression several days after activation.
8262 21849683 Surprisingly, such Treg-dependent limitations in IL-2 signaling by Ag-activated CD8(+) T cells prevent effector differentiation without interfering with memory cell formation.

8267 21849683 Due to this change and the lower IL-2 production that results, a substantial fraction of CD8(+) effector T cells lose CD25 expression several days after activation.
8268 21849683 Surprisingly, such Treg-dependent limitations in IL-2 signaling by Ag-activated CD8(+) T cells prevent effector differentiation without interfering with memory cell formation.
8269 21856357 A detailed analysis of the cell-mediated immune responses by ICS showed the number of specific CD8(+) T cells expressing cytokines (IFN-γ, TNF-α, and IL-2) and granule-associated proteins (CD107a) was higher than that of specific CD4(+) T cells secreted by immune spleen cells upon restimulation in vitro with peptides.
8270 21875636 Similarly, two previously reported promoter IL10 and IL2 polymorphisms (rs1800890 and rs2069762) demonstrated associations with measles-specific cellular immunity in Caucasians (p≤0.034).
8271 21881953 Dengue virus-specific CD4+ and CD8+ T lymphocytes target NS1, NS3 and NS5 in infected Indian rhesus macaques.
8272 21881953 DENV-specific CD4+ and CD8+ T lymphocytes targeted nonstructural (NS) 1, NS3 and NS5 proteins after resolution of peak viremia.
8273 21881953 DENV-specific CD4+ cells expressed interferon-gamma (IFN-γ) along with tumor necrosis factor-alpha (TNF-α), interleukin-2 (IL-2), and macrophage inflammatory protein-1 beta (MIP-1β).
8274 21881953 In comparison, DENV-specific CD8+ cells expressed IFN-γ in addition to MIP-1β and TNF-α and were positive for the degranulation marker CD107a.
8275 21881953 Interestingly, a fraction of the DENV-specific CD4+ cells also stained for CD107a, suggesting that they might be cytotoxic.
8276 21889412 Therefore CMI responses were evaluated in 15 CVID-patients and 15 matched healthy controls (HC) by determining frequencies of interferon (IFN)γ-producing PBMC, and frequencies of IFNγ-, interleukin (IL)-2- and tumour necrosis factor (TNF)α-producing CD4+ and CD8+ T-cells before and after influenza vaccination using IFNγ enzyme-linked immunospot (IFNγ-ELISpot) and flow cytometry.
8277 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.
8278 21921206 Using a total of 28 baboons, different vaccination strategies were used including recombinant Sm-p80 protein formulated in Toll-like receptor 7 and Toll-like receptor 9 agonists, and DNA priming followed by boosting with protein plus adjuvants.
8279 21921206 Production and expression of several cytokines (interleukin 2 [IL-2], interferon γ, IL-12α, IL-1β, IL-6, and IL-22) were up-regulated in vaccinated animals.
8280 21924648 Sequential administration of GM-CSF and IL-2 surface-modified MB49 cells vaccines against the metastatic bladder cancer.
8281 21926463 The lower survival levels observed in memory B cells from ST subjects were the result of disrupted IL-2 signaling that led to increased transcriptional activity of Foxo3a and increased expression of its proapoptotic target TRAIL.
8282 21926463 Our results thus establish a direct role for Foxo3a/TRAIL signaling in the persistence of memory B cells and provide a mechanism for the reduced survival of memory B cells during HIV infection.
8283 21954698 Immune modulators such as IL-2 and anti-CTLA-4 can mediate tumor regression in patients with metastatic melanoma and renal cancer, two tumor types that appear exceptional in their ability to spontaneously harbor endogenous antitumor immune cells.
8284 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.
8285 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.
8286 21956503 However, the number of cells secreting TH2 cytokines IL-4 and IL-5 in hydrogen -peroxide-treated group did not change.
8287 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.
8288 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.
8289 21956503 However, the number of cells secreting TH2 cytokines IL-4 and IL-5 in hydrogen -peroxide-treated group did not change.
8290 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.
8291 21958369 We also detected strong correlations between the proinflammatory cytokines IL-1β, TNF-α, IL-6, and IL-12p40 (p<0.0001).
8292 21966414 Vaccination led to increased levels of CD25+ NK cells, and notably CD56(bright) CD25+ NK cells, whereas decreased amounts of this subset were present in the peripheral blood of influenza infected individuals, and predominantly in study subjects infected with the 2009 pandemic H1N1 influenza virus.
8293 21966414 Finally, acute influenza infection was associated with low plasma concentrations of inflammatory cytokines, including IFN-γ, MIP-1β, IL-2 and IL-15, and high levels of the anti-inflammatory cytokines IL-10 and IL-1ra.
8294 21980478 Four out of the twenty-five 9-mer peptides tested: peptides 3 (F33-41), 13 (F214-222), 14 (F273-281), and 23 (F559-567), were found to bind to HLA-A*0201 with moderate to high affinity and were capable of inducing IFN-γ and IL-2 secretion in lymphocytes from HLA-A*0201 transgenic (HLA-Tg) mice pre-immunized with RSV or recombinant adenovirus expressing RSV F.
8295 21980478 HLA-Tg mice were immunized with these four peptides and were found to induce both Th1 and CD8+ T cell responses in in vitro secondary recall.
8296 21980478 A significant reduction of lung viral load was observed in mice immunized with peptide 23, which appeared to enhance the levels of inflammatory chemokines (CCL17, CCL22, and IL-18) but did not increase eosinophil infiltration in the lungs.
8297 21983362 CBA/J mice immunized with pRON4, pNRON4 or pCRON4 plus a plasmid encoding the granulocyte-macrophage-colony-stimulating factor showed high IgG titers against rRON4S2.
8298 21983362 In addition to the production of IFN-γ, and IL-2, Il-10 and IL-5 were also produced by the spleen cells of the immunized mice stimulated with RON4S2, suggesting that a mixed Th1/Th2 type immune response occurred in all the immunized groups.
8299 22001496 Cytokine analysis of the cervical lymph nodes of mice i.n. immunized with D1-3 or NS1 revealed antigen-specific IL-2 and IL-17 responses, but no IFN-γ T cell response, were observed.
8300 22025707 CD4(+)CD25(+)Forkhead box P3 (Foxp3)(+) regulatory T cells (Tregs) control immune responses to self and foreign antigens in secondary lymphoid organs and at tissue sites of inflammation.
8301 22025707 CD28 signaling is known to abrogate Treg suppression of IL-2 secretion and proliferation, but our studies show that Treg suppression of IFN-γ during Th1 priming proceeds despite enhanced CD28 signaling.
8302 22025707 In vivo, Tregs potently controlled CD4 IFN-γ and CD4 effector cell expansion in the lymph node (four- to fivefold reduction) but not Th1 programming, independent of IL-10.
8303 22025707 Tregs additionally reduced CD4 IFN-γ in the inflamed dermis (twofold reduction) dependent on their production of IL-10.
8304 22046132 In this study, we used a systems biology approach employing a genome-wide yeast-two hybrid interaction screen to identify immunopilins (PPIA, PPIB, PPIH, PPIG, FKBP1A, FKBP1B) as interaction partners of the CoV non-structural protein 1 (Nsp1).
8305 22046132 Overexpression of NSP1 and infection with live SARS-CoV strongly increased signalling through the Calcineurin/NFAT pathway and enhanced the induction of interleukin 2, compatible with late-stage immunopathogenicity and long-term cytokine dysregulation as observed in severe SARS cases.
8306 22057676 SocL extract and wogonin also inhibited the secretion of IL-10 in T(reg) culture; whereas the level of IL-2 was either unchanged or marginally enhanced.
8307 22057676 We also observed an inhibition of Smad-3, GSK-3β and ERK1/2 signaling by SocL and wogonin in T(reg) cells, while phosphorylation of P38 MAPK was considerably enhanced, indicating that SocL or wogonin could inhibit the T cells' response to TGF-β1 via modulation of both Smad and non-Smad signaling pathways.
8308 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.
8309 22064713 Interestingly, the protected mice had significantly decreased levels of antibody response, cytokines (including gamma interferon [IFN-γ], interleukin-2 [IL-2], IL-8, IL-10, and IL-12), and nitric oxide levels after infection with B. rodhaini.
8310 22096993 We revealed that immunization with these particles causes a specific induction of Th1-response, characterized by increased levels ofcytokine TNF-alpha and IL-2.
8311 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.
8312 22158905 Immunotherapy with PI3K inhibitor and Toll-like receptor agonist induces IFN-γ+IL-17+ polyfunctional T cells that mediate rejection of murine tumors.
8313 22158905 Multiple strategies to inhibit PI3K in dendritic cells (DC) each led to suppression of interleukin (IL)-10 and TGF-β but did affect IL-12 or IL-1β induction by the TLR5 ligand flagellin.
8314 22158905 Tumor growth suppression was associated with increased accumulation of polyfunctional T cells that secreted multiple effector cytokines, including IFN-γ, IL-17, and IL-2.

8325 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.

8346 22218690 HCV-specific T cells consisted of both CD4+ and CD8+ T cell subsets; secreted interleukin-2, interferon-γ, and tumor necrosis factor-α; and could be sustained for at least a year after boosting with the heterologous adenoviral vector.
8347 22227565 A key consequence of regulatory T cell (Treg) suppression of CD4 T cells is the inhibition of IL-2 production, yet how Tregs attenuate IL-2 has not been defined.
8348 22227565 To directly define Treg effects on TCR signaling in CD4 T cell targets, we visualized changes in nuclear accumulation of transcription factors at time points when IL-2 was actively suppressed.

8355 22271576 Constitutive STAT5 signaling in activated CD4(+) T cells selectively blocked T(FH) cell differentiation and GCs, and IL-2 signaling was a primary inducer of this pathway.
8356 22271576 Conversely, STAT5-deficient CD4(+) T cells (mature STAT5(fl/fl) CD4(+) T cells transduced with a Cre-expressing vector) rapidly up-regulated Bcl6 expression and preferentially differentiated into T(FH) cells during T cell priming in vivo.
8357 22271576 These results demonstrate that IL-2, STAT5, and Blimp-1 collaborate to negatively regulate T(FH) cell differentiation.

8361 22285888 Also, in both cohorts, the B*0801 and DRB1*0301 alleles, C*0802 and DPA1*0202 alleles, and DRB1*1303 alleles displayed consistent associations with variations in IFN-γ, IL-2 and IL-10 secretion, respectively.
8362 22291184 ID93/SE induced Th2-biased immune responses, whereas ID93/GLA-SE induced multifunctional CD4(+) Th1 cell responses (IFN-γ, TNF-α, and IL-2).
8363 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.
8364 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.

8378 22371375 Simultaneous administration did not enhance antibody levels and lowered the CRM(197)-specific cytokine release of gamma interferon, interleukin-2 (IL-2), IL-5 and IL-13.
8379 22371423 Particularly, our results predict that: (i) Immune complexes IL2/anti-IL2 mAbs, using mAbs which block the interaction of IL2 and CD25 (the alpha chain of IL2 receptor), is the best option to potentate immunity alone or in combination with vaccines.
8380 22371423 These complexes are optimal when a 1:2 molar ratio of mAb:IL2 is used and the mAbs have the largest possible affinity; (ii) Immune complexes IL2/anti-IL2 mAbs, using mAbs which block the interaction of IL2 and CD122 (the beta chain of IL2 receptor), are the best option to reinforce preexistent natural tolerance, for instance to prevent allograft rejection.

8383 22379063 Levels of IgG antibody, gamma interferon (IFN-γ), interleukin 2 (IL-2), IL-12, IL-4, and IL-10 were examined.
8384 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).

8387 22412866 We hypothesized that this immunity depends on polyfunctional memory T cells, i.e., CD4(+) and/or CD8(+) T cells with the capability to simultaneously express several functional markers.
8388 22412866 Significant differences were detected between either of the immune donor groups and naïve individuals for secreted levels of IL-5, IL-6, IL-10, IL-12, IL-13, IFN-γ, MCP-1, and MIP-1β.

8391 22415304 Rv0577 recognizes Toll-like receptor 2 (TLR2) and functionally induces DC maturation by augmenting the expression of cell surface molecules (CD80, CD86, and MHC class I and II) and proinflammatory cytokine production (TNF-α, IL-1β, IL-6, and IL-12p70) in DCs on MyD88-dependent signaling, mitogen-activated protein kinases, and nuclear factor κB signaling pathways.
8392 22415304 In addition, Rv0577-treated DCs activated naive T cells, effectively polarized CD4(+) and CD8(+) T cells to secrete IFN-γ and IL-2, and induced T-cell proliferation, indicating that this protein possibly contributes to Th1-polarization of the immune response.
8393 22415304 More important, unlike LPS, Rv0577-treated DCs specifically induced the proliferation of memory CD4(+)/CD8(+)CD44(high)CD62L(low) T cells in the spleen of M. tuberculosis-infected mice in a TLR2-dependent manner.

8398 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.
8399 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.

8436 22442674 Furthermore, the ΔmmaA4BCG-DDA/TDB vaccine induced significantly higher frequencies of multifunctional (MFT) CD4 T cells expressing both IFNγ and TNFα (double positive) or IFNγ, TNFα and IL-2 (triple positive) than CD4 T cells derived from mice vaccinated with BCG.
8437 22442674 Interestingly, both BCG/adjuvant and ΔmmaA4BCG/adjuvant formulations induced significantly higher frequencies of CD4 T cells expressing TNFα and IL-2 than nonadjuvanted BCG or ΔmmaA4BCG vaccines indicating that BCG/adjuvant mixtures may be more effective at inducing central memory T cells.

8441 22446515 Granulocyte-macrophage colony stimulating factor (GM-CSF) is considered to be the most effective immunostimulating factor for the construction of gene-engineered anti-cancer vaccines.
8442 22446515 A cell line, designated 12B1/GM-CSF/cl-5 producing more than 100 ng/106 cells/24 h, displayed higher pathogenicity than the parental, non-transduced cells.
8443 22446515 Although the tumours induced by the parental 12B1 cells and 12B1/GM-CSF/cl-5 cells appeared nearly at the same time and then grew at an approximately equal rate, the latter mice were in a much poorer clinical condition.
8444 22446515 In both groups of animals splenomegaly was observed; it was much more pronounced in the case of 12B1/GM-CSF/cl-5-inoculated animals.
8445 22446515 When GM-CSF neutralizing antibody was administered to animals inoculated with the 12B1/GM-CSF/cl-5 cells, the pathological changes observed within the organs were suppressed, this proving that the overproduced GM-CSF and not any other substance, played the key role in their induction.
8446 22461525 Heparin-binding hemagglutinin induces IFN-γ(+) IL-2(+) IL-17(+) multifunctional CD4(+) T cells during latent but not active tuberculosis disease.

8475 22509395 Because NKG2D ligands have been shown to be highly expressed in many cancer cells but not in healthy cells, we reason that a chimeric protein consisting of NKG2D linked to IL-2 will lead to the specific targeting of IL-2 to the tumor location.

8502 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.
8503 22564618 With some anti-IL-2 mAbs, injection of IL-2/mAb complexes leads to expansion of CD8 T effector cells but not CD4 T regulatory cells (Tregs); these complexes exert less adverse side effects than soluble IL-2 and display powerful antitumor activity.

8508 22585548 As in human skin, Langerhans cells (LCs) resided exclusively in the macaque epidermis, expressing CD11c, high levels of CD1a and langerin (CD207).

8527 22728225 It similarly enhanced CD4 and CD8 T-cell proliferation and increased influenza-stimulated IL-2, IFN-γ, IL-5, IL-6, and GM-CSF responses.
8528 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.
8529 22750042 The interleukins (ILs) such as IL-2 and IL-12 were added to the vaccine formulation to further enhance the immune response.
8530 22750042 Moreover, CD8+ T-cell, CD4+ T-cell and B-cell populations in different lymphatic organs were elevated in case of vaccinated mice.
8531 22754326 Notably, pigs immunized with the plasmid pEGFP-IL18-M developed significantly higher levels of IFN-γ and IL-2 production response and stronger specific T-lymphocyte proliferation response than the pigs inoculated with the plasmids pEGFP-M and pEGFP-IL18 (P < 0.05).
8532 22798665 We observed that Gag stimulation of macaque PBMCs induced subset-specific NK cell responses in SIV-controlling but not SIV-noncontrolling animals, as well as that circulatory NK cell responses were dependent on Ag-specific IL-2 production by CD4(+) central memory T cells.
8533 22798665 NK cell activation was blocked by anti-IL-2-neutralizing Ab and by CD4(+) T cell depletion, which abrogated the Gag-specific responses.
8534 22798665 We observed that Gag stimulation of macaque PBMCs induced subset-specific NK cell responses in SIV-controlling but not SIV-noncontrolling animals, as well as that circulatory NK cell responses were dependent on Ag-specific IL-2 production by CD4(+) central memory T cells.

8536 22829882 With regard to cytokines, the SAP led to production of interleukin (IL)-2, IL-6, and IL-4.
8537 22829882 IFA promoted production of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-6, IL-17, IL-4, and IL-10.
8538 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.
8539 22829882 With regard to cytokines, the SAP led to production of interleukin (IL)-2, IL-6, and IL-4.
8540 22829882 IFA promoted production of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-6, IL-17, IL-4, and IL-10.
8541 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.
8542 22837100 The results show that vaccination by the multicomponent vaccine prolonged survival of mice challenged with the T. gondii RH strain (from average 4.50 ± 0.22 to 7.60 ± 0.74 days); induced high levels of IgG antibody (from 0.252 ± 0.080 to 0.790 ± 0.083), IFN-gamma (from 598.74 ± 67.50 to 853.77 ± 66.74 pg/ml), and IL-2 (from 89.44 ± 10.66 to 192.24 ± 19.90 pg/ml); changed the CD4(+)/CD8(+) lymphocyte ratio (from 1.81 ± 0.14 to 1.09 ± 0.19); and stimulated NK cell-killing activity (from 46.81 ± 3.96 to 64.15 ± 7.71 %).
8543 22837483 Binding of this receptor to its ligands, B7-H1 (PD-L1) and B7-DC (PD-L2), attenuates T cell activation, reduces IL-2 and IFN-γ secretion, decreases proliferation and cytotoxicity, and induces apoptosis.
8544 22837483 We found that these differences play critical roles in anti-tumor immune effect exhibited by B7-DC-Ig through inhibiting proliferation of PD-1(high) CD4 T cells, leading to a significant decrease in the level of these cells, which are enriched for regulatory T cells, within the tumor.
8545 22837483 In addition, it also leads to a decrease in PD-1(high) CD8 T cells, tipping the balance toward nonexhausted functional PD-1(low) CD8 T cells.
8546 22846987 Furthermore, the elicited IL-2, IL-4 and γ-IFN levels showed good correlation with the degree of protection.
8547 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.
8548 22861368 Based on surface CD69 expression, infants demonstrated activation of vaccine antigen-specific CD4(+) T cells similar to adults.
8549 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(-) .
8550 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.
8551 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.

8562 22871805 FoxP3⁺ regulatory CD4 T cells control the generation of functional CD8 memory.
8563 22871805 The FoxP3(+) regulatory CD4 T-cell subset (Treg) is known as a key suppressive component of the immune system.
8564 22871805 We find that the Tregs act early, during the expansion phase of primary CD8 effectors, by fine tuning interleukin-2 exposure of CD8 memory precursors.
8565 22875619 We isolated phenotypically defined CD4(+) T-cell subpopulations from circulating lymphocytes of DR52b(+) healthy donors by flow cytometry cell sorting and stimulated them in vitro with peptide ESO(119-143), autologous APC and IL-2.
8566 22875619 We isolated ESO-tetramer(+) cells by flow cytometry cell sorting and expanded them with PHA, APC and IL-2 to generate ESO-specific T(H) lines.
8567 22875619 Using this approach, we could consistently generate ESO-tetramer(+) T(H) lines from conventional CD4(+)CD25(-) naïve and central memory populations, but not from effector memory populations or CD4(+)CD25(+) Treg.

8571 22894960 The CD3(+), CD127(+), CD4(+)CD25(+) and CD4(+)Foxp3(+) cells were increased significantly post vaccination.
8572 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.
8573 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.
8574 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.
8575 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.
8576 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.
8577 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.
8578 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.
8579 22912884 Furthermore, we show that distinct polyfunctional (interferon-γ(+), tumor necrosis factor(+), and interleukin-2(+)) Salmonella-specific CD4(+) T cell responses develop with respect to magnitude and kinetics.
8580 22917938 Compared with the wild type and other control groups, mice treated with the combined plant-made vaccines showed significantly higher levels of interferon-γ and interleukin-2 production in response to all four proteins, and higher levels of antigen-specific CD4(+) and CD8(+) T-cell responses and immunoglobulin (Ig) G and IgA titers.
8581 22919627 Levels of IgG1, IgG2a, IgG2b, and IgM, the induction of the cytokines IL-2, IL-4, IL-10, and the production of IFN-γ were measured in lymphocyte cultures.
8582 22927933 On the other hand, when adult mice were primed with BCG.HIVA(CAT) and boosted with MVA.HIVA.85A, HIV-1-specific CD8(+) T-cells producing IFN-γ, TNF-α, IL-2 and CD107a were induced.
8583 22930672 Control of adaptive immune responses by Staphylococcus aureus through IL-10, PD-L1, and TLR2.
8584 22930672 Herein we report that Staphylococcus aureus induces IL-10, Th17-inducing cytokines IL-6 and IL-23, chemokines, and regulates dendritic cell markers.
8585 22930672 S. aureus inhibits T-cell IL-2 responses through modulation of HLA-DR, CD86 and PD-L1.
8586 22930672 IFN-gamma, Src kinase inhibitors, or TLR2 antibodies prevented the down-modulation of HLA-DR by S. aureus.
8587 22930672 IL-10 and PD-L1 antagonists may boost immunity to vaccines for S. aureus and other microbes.
8588 22947140 Anti-DEC:LcrV was more efficient to induce IFN-γ/TNF-α/IL-2 secreting polyfunctional CD4(+) T cells when compared to non-targeted soluble protein vaccine.
8589 22955926 Importantly, we showed that the levels of IL-7R expression and the capacity of HIV-specific CD8 T cells to secrete IL-2 on antigenic restimulation during primary infection were inversely correlated with the viral set-point.
8590 22960496 The splenocytes from this inoculation group secreted moderate levels of IL-5 and IL-10 as well as high amounts of IL-2, cytokines known to act in synergy to induce IgA.
8591 23015648 Coinjection of pVAX/IL-18 significantly increased the production of gamma interferon (IFN-γ), IL-2, IL-4, and IL-10.
8592 23018456 Compared with mice immunized with the homologous lipopeptide/lipopeptide (Lipo/Lipo) vaccine, the Lipo/rAdv5 prime/boost immunized mice 1) developed potent and sustained HSV-specific CD8(+) T cells, detected in both the genital tract draining nodes and in the vaginal mucosa; 2) had significantly lower virus titers; 3) had decreased overt signs of genital herpes disease; and 4) did not succumb to lethal infection (p < 0.005) after intravaginal HSV-2 challenge.
8593 23018456 Polyfunctional CD8(+) T cells, producing IFN-γ, TNF-α, and IL-2 and exhibiting cytotoxic activity, were associated with protection (p < 0.005).
8594 23018461 Amplified CD8(+) T memory development depends upon a critical frequency of Ag-specific T cells and direct responsiveness to IL-2.
8595 23027937 NKT cell-induced proliferation of memory Th1 and Th2 cells was dependent largely on the production of IL-2, with Th2-cell proliferation also affected by loss of IL-4.
8596 23042534 We previously demonstrated that the ovalbumin (OVA)-specific CD4(+) T cell-based (OVA-T(EXO)) vaccine generated using OVA-pulsed dendritic cell (DC(OVA))-released exosomes (EXO(OVA)) stimulate CTL responses via IL-2 and costimulatory CD80 signaling.
8597 23049876 Gag-specific IFN-γ ELISPOT, intracellular cytokine staining (ICS) (CD107a, IFN-γ, TNF-α and IL-2), pentamer staining and T-cell phenotyping were used to differentiate responses to inserts and vectors.
8598 23052765 Results showed that specific antibody, the levels of interleukin-2 (IL-2), interferon-γ (IFN-γ), and the percentages of CD4(+) and CD8(+) T lymphocyte cells were significantly increased in the pVAX1-Rho group.
8599 23059870 This surgery adjuvant approach combined local suicide gene therapy with a subcutaneous vaccine composed by tumor cells extracts and xenogeneic cells producing human interleukin-2 and granulocyte-macrophage colony-stimulating factor.
8600 23071675 We have generated a mucin-type immunoglobulin fusion protein (PSGL-1/mIgG(2b)), which upon expression in the yeast Pichia pastoris became multivalently substituted with O-linked oligomannose structures and bound the macrophage mannose receptor (MMR) and dendritic cell-specific intercellular adhesion molecule-3 grabbing non-integrin (DC-SIGN) with high affinity in vitro.
8601 23071675 Here, its effects on the humoral and cellular anti-ovalbumin (OVA) responses in C57BL/6 mice are presented.OVA antibody class and subclass responses were determined by ELISA, the generation of anti-OVA CTLs was assessed in (51)Cr release assays using in vitro-stimulated immune spleen cells from the different groups of mice as effector cells and OVA peptide-fed RMA-S cells as targets, and evaluation of the type of Th cell response was done by IFN-γ, IL-2, IL-4 and IL-5 ELISpot assays.Immunizations with the OVA - mannosylated PSGL-1/mIgG(2b) conjugate, especially when combined with the AbISCO®-100 adjuvant, lead to faster, stronger and broader (with regard to IgG subclass) OVA IgG responses, a stronger OVA-specific CTL response and stronger Th1 and Th2 responses than if OVA was used alone or together with AbISCO®-100.
8602 23071696 CD154 and IL-2 signaling of CD4+ T cells play a critical role in multiple phases of CD8+ CTL responses following adenovirus vaccination.
8603 23071696 While the role of CD8(+) cytotoxic T lymphocyte (CTL) responses in mediating AdV-induced protection is well understood, the involvement of CD4(+) T cell-provided signals in the development of functional CD8(+) CTL responses remain unclear.
8604 23071696 Without CD4(+) T help, both primary and memory CTL responses were greatly reduced in this model, and were associated with increased PD-1 expression.
8605 23071696 These effects were specifically mediated by CD4(+) T cell-produced IL-2 and CD154 signals.

8641 23184617 Nevertheless, after immunization with higher doses of the targeted vaccine, the capacity of vaccine-induced CD8(+) T cells to produce the cytokine IL-2 was diminished and the CD8(+) T-cell response was dominated by an effector memory phenotype (CD62L(-)/CD127(+)) in contrast to the effector phenotype (CD62L(-)/CD127(-)) observed after non-targeted antigen delivery.
8642 23196208 The transgenic rice seeds expressing the MOMP protein were administered by the oral route to BALB/c mice, which developed MOMP-specific serum IgG and fecal IgA antibodies and a splenocyte MOMP-specific proliferative response and significant levels of IFN-γ, IL-2, IL-4, IL-5 and TGF-β production.

8647 23226275 Polyfunctional analysis revealed a pattern of TNFα and IL-2 responses by CD4+ T cells and TNFα and IFNγ responses by CD8+ T cells to F4 peptides.
8648 23226275 HIV-specific CD4+ and CD8+ T cells expressing cytokines waned in peripheral blood lymphocytes by day 84, but CD8+ T cell responses to F4 peptides could still be detected in lymphoid tissues more than 3 months after vaccination.

8650 23228812 Upon in vitro stimulation of splenocytes from mice immunized with recombinant Ag85B, the highest levels of secreted IFN-γ and IL-2 were detected in mice immunized with the autophagy-inducing plasmid, while no differences in IL-4 levels were detected between the groups, suggesting that the DNA vaccine regimen with autophagy induction induced primarily a Th1 immune response.
8651 23250629 Total 20 mutations in interleukin-2 receptor subunit gamma (IL2RG) were identified in 22 patients, including 11 novel mutations.
8652 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.
8653 23267892 [Prediction of WT1/MUC1 peptide dendritic cell therapy responders by quantification of ex vivo induced mRNA in whole blood].
8654 23267892 To challenge this classic problem, we quantified 17 different leukocyte function-associated mRNAs( IFN-γ,TNFSF1, TNFSF2, TNFSF5, IL-10, TGF β,CTLA4, PD1, FOXP3, GMCSF, VEGF, IL-8, CCL8, CXCL3, and IL-2) in whole blood after ex vivo stimulation with 7 different agents(PHA, HAG, zymosan, IFN-γ,rIL-2, aTCR, and picibanil) to activate various subsets of leukocytes.

8658 23277917 Secretion of the cytokines interferon-γ, interleukin-1β, interleukin-2 and interleukin-10 in the CD4(+) T cell : DC co-culture (with or without chemokine pre-treatment) were essentially the same.
8659 23277917 Chemokine programming of DCs with a 7 : 3 ratio of CCL3 : CCL19 followed by LPS treatment maintained partial immature phenotypes of DCs, as indicated by surface marker (CD80 and CD86) expression over time.

8663 23318779 Activation markers (CD25 and CD69) were measured after 44h (n=8), cytokines in supernatant after 3 and 7days, and intracellular cytokine staining (ICS) of proliferated cells (identified by dye dilution) after 7days (n=6).
8664 23318779 Vaccination increased TT-specific expression of CD25 and CD69 on CD3(+)CD4(+) lymphocytes, and TT-specific proliferation at 7, 14 and 28days post vaccination.
8665 23318779 Vaccination induced TT-specific Th1 (IFN-γ, TNF-α, and IL-2) Th2 (IL-13, IL-5, and IL-4), Th17 (IL-17A) and IL-10(+) cells as measured by ICS.
8666 23318779 TT-specific Th1 cells were the most abundant (12-15% of all TT-specific CD4(+) T-cells) while IL10(+) (1.8%) Th17 (1.1%) and Th2 cells (0.2-0.6%) were less abundant.

8668 23333555 We show that CD4+ and CD8+ Teffector/memory (T(EM)) and other subsets produce IL-17A following SEB stimulation.
8669 23333555 We also show that IL-17A is co-produced with other pro-inflammatory cytokines (i.e., IL-2, IFN-γ and TNF-α).
8670 23333555 Multifunctional IL-17A producing cells possess markers typical of the T(H)17/T(C)17 and T(H)1 subsets, including CCR6, IL-22, and transcription factors retinoic acid receptor-related orphan nuclear receptor (ROR)-γt and T-bet.

8683 23359502 IL-2 produced by CD8+ immune T cells can augment their IFN-γ production independently from their proliferation in the secondary response to an intracellular pathogen.
8684 23359502 In the current study, we examined the role of IL-2 in IFN-γ production by CD8(+) immune T cells in their secondary responses using T. gondii-specific CD8(+) T cell hybridomas and splenic CD8(+) immune T cells from chronically infected mice.

8732 23377669 A major challenge associated with allogeneic hematopoietic stem cell transplantation is effective prevention and/or attenuation of symptoms associated with acute graft-versus-host disease (aGVHD) that can result from a failure of either host and/or donor CD4(+)CD25(+) regulatory T (Tr) and CD8(+)CD28 suppressor T (Ts) cells to dampen immunopathogenic responses mediated by alloreactive donor CD4(+)CD28(+) Th1 (Th1) and CD8(+)CD28(-) Tc1 (Tc1) cell-mediated inflammatory processes.
8733 23377669 In addition, immunized mice presented with significantly diminished Th1-cytokines interferon-γ and interleukin-2 response and a moderately upregulated Th2-cytokine interleukin-10 and Th3-cytokine transforming growth factor-β response.
8734 23382205 Transfer of conventional CD4(+) T cells from FI-RSV-vaccinated mice into naive RSV-infected recipients also caused a reduction in airway Treg responses; boosting Tregs with IL-2 immune complexes failed to restore normal levels of Tregs or to ameliorate disease.
8735 23390298 Selection of rAd vector or dose could modulate the proportion and/or frequency of IFN-γ(+)TNF-α(+)IL-2(+) and KLRG1(+)CD127(-)CD8(+) T cells, but strikingly ∼30-80% of memory CD8(+) T cells coexpressed CD127 and KLRG1.
8736 23408524 Flow cytometric analysis showed that the increase in IFN-γ correlated with proliferation and activation (increased expression of CD25) of CD4, CD8, and γδT cells, but this response was significantly higher in ΔleuD-vaccinated animals at some time points after challenge.
8737 23408524 However, significantly higher levels of IFN-γ (at weeks 26 and 30), interleukin-2 (IL-2; week 18), IL-1b (weeks 14 and 22), IL-17 (weeks 18 and 22), and IL-23 (week 18) and a significantly lower level of IL-10 (weeks 14 and 18) and transforming growth factor β (week 18) were detected in the ΔleuD-vaccinated group.
8738 23408627 A comparative evaluation of the immunity stimulated with a vaccine regimen that includes simian immunodeficiency virus (SIV), interleukin 2 (IL-2), and IL-15 DNAs, recombinant modified vaccinia virus Ankara (rMVA), and inactivated SIVmac239 particles administered into the oral and nasal cavities, small intestine, and vagina was carried out in female rhesus macaques to determine the best route to induce diverse anti-SIV immunity that may be critical to protection from SIV infection and disease.
8739 23408627 All four immunizations generated mucosal SIV-specific IgA.
8740 23408627 Oral immunization was as effective as vaginal immunization in inducing SIV-specific IgA in vaginal secretions and generated greater IgA responses in rectal secretions and saliva samples compared to the other immunization routes.
8741 23408627 Vaccination also induced CD4(+) and CD8(+) T-cell responses in the rectal and vaginal mucosa with greater functional heterogeneity than in blood samples.
8742 23408627 Significantly higher CD8(+) granzyme B-positive T-cell responses were observed systemically after intestinal vaccination and in rectal cells after oral immunization.
8743 23408627 The majority of SIV-specific T cells that produced granzyme B did not produce cytokines.
8744 23416095 A limited association was found between TRIM5 (rs7122620) and TRIM25 (rs205499) gene polymorphisms and measles-specific antibody levels.
8745 23416095 However, many associations were found between TRIM gene SNPs and variations in cellular responses (IFN-γ Elispot and secreted cytokines IL-2, IL-6, IL-10, IFN-γ, and TNF-α).
8746 23416095 We also identified polymorphisms in the TRIM5, TRIM22, and TRIM25 genes that were associated with significant differences in cytokine responses.
8747 23433648 Cytokine profiling in the co-immunization group showed a significant increase in the levels of IL-2, IL-4, IL-6 and IFN-γ in the splenocytes of mice upon stimulation with the recombinant Ts87 protein; however, the expression of IL-17 was down-regulated.
8748 23436220 The concentrations of IL-2, IL-4, GM-CSF, MCP-1 and Rantes in serum, and IL-1α in mesenteric lymph node and MIP-1β in spleen were significantly increased by DON treatment compared to control.
8749 23436220 The concentrations of IL-2, IL-5, IL-6, IL-9, IL-12, IL-13 and Rantes in thymus, of IL-2 in spleen, and of IL-1α, IL-1β, IL-3, IL-5, IL-10, IL-17, G-CSF, GM-CSF and MCP-1 in mesenteric lymph nodes were significantly decreased in mice compared to those in the Vac group, while concentrations of IL-1α, IL-2, IL-9, IL-13,G-CSF, GM-CSF, IFN-γ, MCP-1, MIP-1α and TNF-α were significantly increased in serum compared to the Vac group.
8750 23436220 The concentrations of IL-2, IL-4, GM-CSF, MCP-1 and Rantes in serum, and IL-1α in mesenteric lymph node and MIP-1β in spleen were significantly increased by DON treatment compared to control.
8751 23436220 The concentrations of IL-2, IL-5, IL-6, IL-9, IL-12, IL-13 and Rantes in thymus, of IL-2 in spleen, and of IL-1α, IL-1β, IL-3, IL-5, IL-10, IL-17, G-CSF, GM-CSF and MCP-1 in mesenteric lymph nodes were significantly decreased in mice compared to those in the Vac group, while concentrations of IL-1α, IL-2, IL-9, IL-13,G-CSF, GM-CSF, IFN-γ, MCP-1, MIP-1α and TNF-α were significantly increased in serum compared to the Vac group.
8752 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).
8753 23439306 Boosting LVS ΔcapB-primed mice with rLm/iglC significantly enhanced T cell immunity; their splenic T cells secreted significantly more gamma interferon (IFN-γ) and had significantly more cytokine (IFN-γ and/or tumor necrosis factor [TNF] and/or interleukin-2 [IL-2])-producing CD4(+) and CD8(+) T cells upon in vitro IglC stimulation.
8754 23453731 IN, but not IR, immunization of mice with 2/6-VLP alone induced antigen-specific IL-10 and IL-17 secreting T cells.
8755 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.
8756 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.
8757 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.
8758 23453731 IN, but not IR, immunization of mice with 2/6-VLP alone induced antigen-specific IL-10 and IL-17 secreting T cells.
8759 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.
8760 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.
8761 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.
8762 23454005 The new protocol was subsequently compared to an established protocol, previously used in vaccine studies, based on polyclonal antibodies without biotin avidin amplification and activation of memory B-cells using a mix of antigen, CpG, IL-2 and IL-10.
8763 23455713 Once there, primed T cells became dysfunctional and underwent antigen-driven, interferon-γ (IFN-γ)- and Fas ligand (FasL)-mediated apoptosis, resulting in hyporesponsiveness to subsequent vaccination.
8764 23455713 Provision of CD40-specific antibody, Toll-like receptor 7 (TLR7) agonist and interleukin-2 (IL-2) reduced T cell apoptosis but did not prevent vaccination-site sequestration.
8765 23465748 B3T1 stimulated cells showed moderate levels of IFN-γ and IL-2 but higher levels of IL-4.
8766 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.
8767 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.
8768 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.
8769 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.
8770 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.

8774 23480362 F1-MAP with CpG oligodeoxynucleotide (CpG-ODN) as an adjuvant showed enhanced in vitro T cell proliferation and Th1 (IL-2, IFN-γ and TNF-α) and Th17 (IL-17A) cytokine secretion.
8775 23480362 Moreover, F1-MAP with CpG formulation showed significantly high (P < 0.001) percentage of CD4(+) IFN-γ(+) cells as compared to CD8(+) IFN-γ(+) cells, and also more (CD4- IFN-γ)(+) cells secrete perforin and granzyme as compared to (CD8- IFN-γ)(+) showing Th1 response.
8776 23480362 Thus, the study highlights the importance of Th1 cytokine and existence of CD4(+) and CD8(+) immune response.
8777 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.
8778 23486418 Markers of innate immune activation (lipopolysaccharide [LPS] and lipopolysaccharide-binding protein [LBP]) were significantly lower in ETB than in PTB children.
8779 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.
8780 23486778 Induction of ICOS+CXCR3+CXCR5+ TH cells correlates with antibody responses to influenza vaccination.
8781 23486778 The induction of ICOS was largely restricted to CD4+ T cells coexpressing the chemokine receptors CXCR3 and CXCR5, a subpopulation of circulating memory T follicular helper cells.
8782 23486778 Up to 60% of these ICOS+CXCR3+CXCR5+CD4+ T cells were specific for influenza antigens and expressed interleukin-2 (IL-2), IL-10, IL-21, and interferon-γ upon antigen stimulation.
8783 23486778 The increase of ICOS+CXCR3+CXCR5+CD4+ T cells in blood correlated with the increase of preexisting antibody titers, but not with the induction of primary antibody responses.
8784 23486778 Consistently, purified ICOS+CXCR3+CXCR5+CD4+ T cells efficiently induced memory B cells, but not naïve B cells, to differentiate into plasma cells that produce influenza-specific antibodies ex vivo.
8785 23486778 Thus, the emergence of blood ICOS+CXCR3+CXCR5+CD4+ T cells correlates with the development of protective antibody responses generated by memory B cells upon seasonal influenza vaccination.
8786 23490396 ELISpot assays for HCV-induced interferon (IFN)-γ and interleukin (IL)-2 production by T lymphocytes, as well as multiplex in vitro cytokine production assays, were performed.
8787 23490396 The IFN-γ ELISpot responses involved both CD4 and CD8 T lymphocytes and were comparable in magnitude, but narrower in specificity, in uninfected subjects than in seroconverters.
8788 23490396 A subset of seronegative subjects had HCV-induced cytokine production patterns comparable with the seroconverters with increased production of IFN-γ, IL-2 and tumour necrosis factor (TNF)-α and reduced IL-10 in response to nonstructural peptides.

8792 23502768 The serum levels of interleukin-2 and interferon-γ (P<0.05) as well as the percentage of natural killer and CD4+T cells increased significantly (P<0.05) after the vaccination.

8830 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.
8831 23632305 Adults had vaccine antigen-specific Th1 and Th2 cells responsive to all antigens evaluated whereas young children had significant numbers of vaccine antigen-specific CD4(+) T cells producing IL-2, (p=0.004).
8832 23632305 Vaccine antigen-specific CD4(+) T-cell populations in adults were largely of effector (TEM) and/or central memory (TCM) phenotypes as defined by CD45RA(-)CCR7(+) or CD45RA(-)CCR7(-) respectively; however among young children antigen-specific IL-2 producing CD4(+) T cells demonstrated CD45RA(+) expression (non-memory cells).
8833 23632305 Adults had vaccine antigen-specific Th1 and Th2 cells responsive to all antigens evaluated whereas young children had significant numbers of vaccine antigen-specific CD4(+) T cells producing IL-2, (p=0.004).
8834 23632305 Vaccine antigen-specific CD4(+) T-cell populations in adults were largely of effector (TEM) and/or central memory (TCM) phenotypes as defined by CD45RA(-)CCR7(+) or CD45RA(-)CCR7(-) respectively; however among young children antigen-specific IL-2 producing CD4(+) T cells demonstrated CD45RA(+) expression (non-memory cells).
8835 23638188 The P domain complexes induced significant central memory CD4(+) T cell phenotypes (CD4(+) CD44(+) CD62L(+) CCR7(+)) and activated polyclonal CD4(+) T cells as shown by production of Interleukin (IL)-2, Interferon (IFN)-γ, and Tumor Necrosis Factor (TNF)-α.
8836 23638188 Furthermore, P domain complexes efficiently induced bone marrow-derived dendritic cell (BMDC) maturation, evidenced by up-regulation of co-stimulatory and MHC class II molecules, as well as production of IL-12 and IL-1β.
8837 23644075 IpaB- and IpaD-specific IgA antibody-secreting cells in the lungs and spleen and T-cell-derived IL-2, IL-5, IL-17 and IL-10 were associated with protection.
8838 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.
8839 23651196 Human Th17 cells express RORC and CD161 and originate from RORC-expressing CD161(+) precursors, which migrate to lymphoid tissue and differentiate into mature Th17 cells in response to interleukin (IL)-1β and IL-23.
8840 23651196 Human Th17 cells are rare in inflammed tissues for two reasons: (1) Th17 cells do not produce IL-2 and, therefore, do not proliferate in response to TCR signaling, mainly because of RORC-dependent IL-4I1-mediated mechanisms that interfere with IL-2 gene activation; and (2) Th17 cell shift to a Th1 phenotype in the presence of IL-12; such Th17-derived Th1 cells are considered to be nonclassical Th1 cells and can be distinguished from classical Th1 cells.
8841 23667513 Consensus HIV-1 FSU-A integrase gene variants electroporated into mice induce polyfunctional antigen-specific CD4+ and CD8+ T cells.
8842 23667513 Multiparametric FACS demonstrated that CD8+ and CD4+ T cells of gene-immunized mice stimulated with IN-derived peptides secreted IFN-γ, IL-2, and TNF-α.
8843 23667513 The multi-cytokine responses of CD8+ and CD4+ T-cells correlated with the loss of in vivo activity of the luciferase reporter gene co-delivered with pVaxIN plasmids.
8844 23667513 This indicated the capacity of IN-specific CD4+ and CD8+ T-cells to clear IN/reporter co-expressing cells from the injection sites.
8845 23667513 Thus, the synthetic HIV-1 clade A integrase genes acted as potent immunogens generating polyfunctional Th1-type CD4+ and CD8+ T cells.

8882 23676757 The study shows that transcription of SEC14L1, GUSB, BPI, CCR7 and TGFβ-1 (all P ≤ 0.05) was downregulated in TB disease compared with uninfected controls, while transcription of RAB33A was downregulated in TB disease compared with both latent TB (P < 0.05) and controls (P < 0.01).
8883 23676757 The transcription of CD4, TGFβ-1 (P < 0.01) and the expression of IL-2 (P < 0.01) and IL-13 (P < 0.05) was upregulated in latent TB compared with that in controls.

8916 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.
8917 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.

8927 23716300 MyD88 and TRIF synergistic interaction is required for TH1-cell polarization with a synthetic TLR4 agonist adjuvant.
8928 23716300 Different TLR4 agonists may preferentially signal via MyD88 or TIR-domain-containing adapter inducing IFN-beta (TRIF) to exert adjuvant effects; however, the contribution of MyD88 and TRIF signaling to the induction of polyclonal T(H)1 responses by TLR4 agonist adjuvants has not been studied in vivo.
8929 23716300 To determine whether GLA-SE preferentially signals through MyD88 or TRIF, we evaluated the immune response against a candidate tuberculosis (TB) vaccine Ag following immunization of mice lacking either signaling adapter compared with that of wild-type mice.
8930 23716300 We find that both MyD88 and TRIF are necessary for GLA-SE to induce a poly-functional T(H)1 immune response characterized by CD4(+) T cells producing IFN-γ, TNF, and IL-2, as well as IgG2c class switching, when paired with the TB vaccine Ag ID93.
8931 23716300 We demonstrate that MyD88 and TRIF must be expressed in the same cell for the in vivo T(H)1-skewing adjuvant activity, indicating that these two signaling pathways cooperate on an intracellular level.
8932 23716300 Thus engagement of both the MyD88 and TRIF signaling pathways are essential for the effective adjuvant activity of this TLR4 agonist.
8933 23727003 A single dose of vaccine effectively activated T cells with an expansion peak on day 10 post immunization and elicited memory CD4(+) and CD8(+) T cells that produced IFN-γ, TNF-α and IL-2 upon restimulation with CHIKV/IRES.

8940 23748671 The expanded Tregs expressed high levels of FOXP3, CTLA4 and HELIOS compared to conventional T cells and were shown to be highly suppressive.
8941 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.
8942 23760241 Infection of B cells resulted in the significant upregulation of early markers of B cell activation and antigen presentation, including CD69, major histocompatibility complex class II (MHC-II), and CD40 in murine B cells or HLA-DR and CD40 in human B cells compared to mock-infected cells or cells treated with an inactivated RABV-based vaccine.
8943 23760241 Furthermore, primary B cells infected with a live RABV expressing ovalbumin were able to prime and stimulate naive CD4(+) OT-II T cells to proliferate and to secrete interleukin-2 (IL-2), demonstrating a functional consequence of B cell infection and activation by live RABV-based vaccine vectors.
8944 23772631 First, IBTs were proposed either to help restore CD4(+) T-cell counts in cases of therapeutic failures with cytokines, interleukin-2 (IL-2) or IL-7, or to better control HIV and disease progression during treatment interruptions with anti-HIV therapeutic candidate vaccines.

8958 23802595 In particular, a HLA-B*40:01 restricted CD8+ T cell response recognizing the CAIX- derived peptide SEEEGSLKL was identified.
8959 23806267 We observed statistically significant sex-related differences in the secretion of IL-2 (p<0.001), IL-1β (p<0.001) and IL-10 (p=0.017).
8960 23825389 DCs treated with RpfB displayed features of mature and functional status, with elevated expression of cell surface molecules (CD80, CD86, and MHC class I and II) and proinflammatory cytokine production (TNF-α, IL-1β, IL-6, and IL-12p70).
8961 23825389 RpfB-treated DCs effectively polarized naïve CD4(+) and CD8(+) T cells to secrete IFN-γ and IL-2.
8962 23825389 Importantly, RpfB induced the expansion of memory CD4(+)/CD8(+)CD44(high)CD62L(low) T cells in the spleen of M. tuberculosis-infected mice.
8963 23836827 Significantly higher levels of gamma interferon (IFN-γ)/interleukin-2 (IL-2)/tumor necrosis factor (TNF) multifunctional T cells were noted in immunized mice than in control mice.
8964 23836827 We also report the first identification of minimal CD8(+) and CD4(+) T cell epitopes on Plasmodium yoelii AMA-1.
8965 23840706 Delivery of LmSTI1a to adjuvant-matured DCs increased the frequency of antigen-specific CD4(+) T cells producing IFN-γ(+), IL-2(+), and TNF-α(+) in two different strains of mice (C57BL/6 and Balb/c), while such responses were not observed with the same doses of a control Ig-LmSTI1a mAb without receptor affinity or with non-targeted LmSTI1a protein.
8966 23840706 Using a peptide library for LmSTI1a, we identified at least two distinct CD4(+) T cell mimetopes in each MHC class II haplotype, consistent with the induction of broad immunity.
8967 23840706 When we compared T cell immune responses generated after targeting DCs with LmSTI1a or other L. major antigens, including LACK (Leishmania receptor for activated C kinase) and LeIF (Leishmania eukaryotic ribosomal elongation and initiation factor 4a), we found that LmSTI1a was superior for generation of IFN-γ-producing CD4(+) T cells, which correlated with higher protection of susceptible Balb/c mice to a challenge with L. major.

8985 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.
8986 23873619 A downregulation of the IL-1α, a Th1 cytokine in response to FABP and GST immunization in these calves, was also observed.

8988 23874793 We found that M. bovis BCG mediates apoptosis of NK cells only in the context of IL-2 stimulation during which CD56(bright) NK cells are releasing IFN-γ in response to mycobacteria.
8989 23874793 We found that the presence of mycobacteria prevented the IL-2 induced proliferation and surface expression of NKp44 receptor by the CD56(bright) population.

8996 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.

9003 23910466 In present study, we constructed a multi-adjuvant WCTV based on the nanoparticles modified with cell penetrating peptide, which could facilitate the transportation of granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin 2 (IL-2) into tumor cells.
9004 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.
9005 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.
9006 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.
9007 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.
9008 23928460 In contrast to rSAG1, which only stimulated the release of IFN-γ and IL-2, rROP5 induced the specific production of IL-10, the Th2-type cytokine, in addition to IFN-γ and IL-2.
9009 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.
9010 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.
9011 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.
9012 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.
9013 23933364 IL-13Rα2) vaccines significantly enhanced CD8 expression levels on HIV-specific CD8(+), T cells, which correlated with avidity.
9014 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.
9015 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.

9021 23950909 Significant levels of Th2 and anti-inflammatory cytokines transcripts (IL-4, IL-10, IL-13, TGF-β) were expressed but their level was low and with a pattern similar to the control group.
9022 23954198 Based on in vitro assay, 6-O-palmitoyl Agnuside (AG-3) was further taken up for detailed in vivo activity and found to significantly enhance the production of anti OVA IgG titer, neutralizing antibody (IgG1 and IgG2a) titer as well as soluble mediators of a Th1 (IL-2, IFN-γ)/Th2 response (IL-4) and proliferation of T lymphocyte subsets (CD4/CD8) and co stimulatory molecules CD80/CD86.
9023 23966552 The CD3(+) CD4(-) CD8(hi) T cell population was the first and major source of CSFV-specific IFN-γ.
9024 23966552 A proportion of these cells showed evidence for cytotoxicity, as evidenced by CD107a mobilization, and coexpressed tumor necrosis factor alpha (TNF-α).
9025 23966552 While virus-specific CD4 T cell (CD3(+) CD4(+) CD8α(+)) responses were detected, the dominant response was again from the CD8 T cell population, with the highest numbers of these cells being detected 14 and 7 days after the primary and secondary challenges, respectively.
9026 23966552 These CD8 T cells were further characterized as CD44(hi) CD62L(-) and expressed variable levels of CD25 and CD27, indicative of a mixed effector and effector memory phenotype.
9027 23966552 The majority of virus-specific IFN-γ(+) CD8 T cells isolated at the peaks of the response after each challenge displayed CD107a on their surface, and subpopulations that coexpressed TNF-α and interleukin 2 (IL-2) were identified.
9028 23967128 Our results showed that the group immunised with 30 μg rTgPDI showed significantly higher levels of specific antibodies against the recombinant protein, a strong lymphoproliferative response and significantly higher levels of IgG2a, IFN-gamma (IFN-γ), IL-2 and IL-4 production compared with other doses and control groups.
9029 23977084 Priming with the individual rBCGΔpanCD vaccines or the mix and boosting with SAAVI MVA-C also resulted in the generation of HIV-specific CD4(+) and CD8(+) T cells producing IFN-γ and TNF-α and CD4(+) cells producing IL-2.
9030 23977248 In contrast, in mice vaccinated with adjuvanted recombinant H28 alone (H28/H28) we observed the highest production of IL-2 per single cell and the highest frequency of antigen specific TNF-α/IL-2 expressing CD4 T cells pre and post infection.
9031 23977248 Interestingly, TNF-α/IL-2 expressing central memory-like CD4 T cells showed a significant positive correlation with protection at week 6 post infection, whereas the opposite was observed for post infection CD4 T cells producing only IFN-γ.
9032 23977248 Taken together, our data showed that the adjuvanted subunit and MVA strategies led to different T cell subset combinations pre and post infection and that TNF-α/IL-2 double producing but not IFN-γ single producing CD4 T cell subsets correlated with protection in the mouse TB model.
9033 23977248 In contrast, in mice vaccinated with adjuvanted recombinant H28 alone (H28/H28) we observed the highest production of IL-2 per single cell and the highest frequency of antigen specific TNF-α/IL-2 expressing CD4 T cells pre and post infection.

9039 23980113 Here, we have further characterized vaccine-induced changes in the CD8(+) T cell phenotype and demonstrated significant upregulation of CD11c on CD3(+) CD8b(+) T cells in the liver, spleen, and peripheral blood.
9040 23980113 CD11c(+) CD8(+) T cells are predominantly CD11a(hi) CD44(hi) CD62L(-), indicative of antigen-experienced effector cells.
9041 23980113 Following in vitro restimulation with malaria-infected hepatocytes, CD11c(+) CD8(+) T cells expressed inflammatory cytokines and cytotoxicity markers, including IFN-γ, tumor necrosis factor alpha (TNF-α), interleukin-2 (IL-2), perforin, and CD107a.
9042 23980113 CD11c(-) CD8(+) T cells, on the other hand, expressed negligible amounts of all inflammatory cytokines and cytotoxicity markers tested, indicating that CD11c marks multifunctional effector CD8(+) T cells.
9043 23980113 Coculture of CD11c(+), but not CD11c(-), CD8(+) T cells with sporozoite-infected primary hepatocytes significantly inhibited liver-stage parasite development.
9044 23980113 Tetramer staining for the immunodominant circumsporozoite protein (CSP)-specific CD8(+) T cell epitope demonstrated that approximately two-thirds of CSP-specific cells expressed CD11c at the peak of the CD11c(+) CD8(+) T cell response, but CD11c expression was lost as the CD8(+) T cells entered the memory phase.
9045 23980113 Further analyses showed that CD11c(+) CD8(+) T cells are primarily KLRG1(+) CD127(-) terminal effectors, whereas all KLRG1(-) CD127(+) memory precursor effector cells are CD11c(-) CD8(+) T cells.
9046 23986600 We have reported previously that ocular infection of different strains of mice with recombinant herpes simplex virus 1 (HSV-1) constitutively expressing interleukin-2 (IL-2) provokes central nervous system (CNS) demyelination and optic neuropathy, as determined by changes in visual evoked cortical potentials and pathological changes in the optic nerve and CNS, whereas recombinant viruses expressing IL-4, gamma interferon, IL-12p35, IL-12p40, or IL-12p70 do not induce this neuropathy.
9047 24007495 The combination of a coadministered plasmid encoding IL-2, optimization of the coding sequence for mammalian cells, and the use of different delivery routes resulted in enhancements of the E7-specific cytotoxic CD8(+) T-cell responses and full therapeutic protection under experimental conditions.
9048 24015262 The recombinant protein elicited a mixed Th1/Th2 type of protective immune response as evidenced by the generation of both pro- and anti-inflammatory cytokines IL-2, IFN-γ, TNF-α, IL-4 and an increased production of antibody isotypes IgG1, IgG2a, IgG2b and IgA.
9049 24030809 IFN-α8 and -α10 most potently enhanced expression of IFN-γ, IL-2, and IL-4.
9050 24030809 While enhancement of IL-2 and IL-4 correlated with the time of preincubation with type I IFN, IFN-γ production was enhanced best when IFN-α was added immediately preceding or simultaneously with T-cell stimulation.
9051 24030809 IFN-α8 and -α10 most potently enhanced expression of IFN-γ, IL-2, and IL-4.
9052 24030809 While enhancement of IL-2 and IL-4 correlated with the time of preincubation with type I IFN, IFN-γ production was enhanced best when IFN-α was added immediately preceding or simultaneously with T-cell stimulation.
9053 24031690 The transferrin binding protein A (TbpA) has been found to act as immunogen and potent vaccine candidate in various Gram negative bacteria including P. multocida.
9054 24031690 The tbpA gene of P. multocida serotype B:2 was cloned in a mammalian expression vector alone and along with murine IL2 gene as immunological adjuvant to produce monocistronic and bicistronic DNA vaccine constructs, respectively.
9055 24036137 Mucosal immunization of mice with recombinant L. lactis NZ9000 containing the UreB-IL-2 protein elicited more anti-UreB antibody that specifically bounded to the purified bacterial UreB protein and more cytokines such as IFN-γ, IL-4, and IL-17, and had a lower H. pylori burden and urease activity than control mice.
9056 24039703 Interferon (IFN)-γ and interleukin (IL)-2 producing PPD-specific CD4 T cells were analysed longitudinally before each instillation using a rapid flow-cytometric whole blood immunoassay.
9057 24055089 Statistical analysis indicated 6 genes, namely IFNG, IL2, XCL1, CD69, CSF2 and CXCL10, as significantly upregulated by PTx which was also demonstrated at the protein level for genes encoding secreted proteins.
9058 24056771 Higher frequencies of pre-existing T cells to conserved CD8 epitopes were found in individuals who developed less severe illness, with total symptom score having the strongest inverse correlation with the frequency of interferon-γ (IFN-γ)(+) interleukin-2 (IL-2)(-) CD8(+) T cells (r = -0.6, P = 0.004).
9059 24056771 Within this functional CD8(+)IFN-γ(+)IL-2(-) population, cells with the CD45RA(+) chemokine (C-C) receptor 7 (CCR7)(-) phenotype inversely correlated with symptom score and had lung-homing and cytotoxic potential.

9067 24089189 For CD8 T cells, all adjuvants induced a comparable response magnitude, but combining poly I:C with ISCOMs induced a high frequency of CD127(+), IL-2-producing cells with decreased expression of Tbet compared with either adjuvant alone.
9068 24089189 For CD4 T cells, combining poly I:C and ISCOMs increased the frequency of multifunctional cells, producing IFN-γ, IL-2, and TNF, and the total magnitude of the response compared with either adjuvant alone.

9073 24090087 Splenocytes from rBsc-PYP-1/FCA-immunized mice secreted low levels of T helper (Th)1-type cytokines, interferon-γ and interleukin (IL)-2, while producing significantly high levels of IL-10 and significantly elevated levels of IL-4 (Th2 cytokines) after stimulation with rBsc-PYP-1 in vitro.
9074 24099936 The results showed that PFM at high and medium doses was able to overcome the CTX-induced immunosuppression, significantly increases the immune organ indexes, enhances lymphocyte proliferation and improves the concentrations of IL-2 and IL-6 in serum when compared with PF.
9075 24101547 Asymptomatic HLA-A*02:01-restricted epitopes from herpes simplex virus glycoprotein B preferentially recall polyfunctional CD8+ T cells from seropositive asymptomatic individuals and protect HLA transgenic mice against ocular herpes.
9076 24101547 In this study, we used multiple prediction algorithms to identify 10 potential HLA-A*02:01-restricted CD8(+) T cell epitopes from the HSV-1 gB amino acid sequence.
9077 24101547 In 10 sequentially studied HLA-A*02:01-positive, HSV-1-seropositive ASYMP individuals, the most frequent, robust, and polyfunctional CD8(+) T cell responses, as assessed by a combination of tetramer, IFN-γ-ELISPOT, CFSE proliferation, CD107a/b cytotoxic degranulation, and multiplex cytokine assays, were directed mainly against epitopes gB342-350 and gB561-569.
9078 24101547 In contrast, in 10 HLA-A*02:01-positive, HSV-1-seropositive symptomatic (SYMP) individuals (with a history of numerous episodes of recurrent clinical herpes disease) frequent, but less robust, CD8(+) T cell responses were directed mainly against nonoverlapping epitopes (gB183-191 and gB441-449).
9079 24101547 ASYMP individuals had a significantly higher proportion of HSV-gB-specific CD8(+) T cells expressing CD107a/b degranulation marker and producing effector cytokines IL-2, IFN-γ, and TNF-α than did SYMP individuals.
9080 24101547 Moreover, immunization of a novel herpes-susceptible HLA-A*02:01 transgenic mouse model with ASYMP epitopes, but not with SYMP epitopes, induced strong CD8(+) T cell-dependent protective immunity against ocular herpes infection and disease.
9081 24126533 In contrast to the functional exhaustion of T cells observed after chronic infection, M. tuberculosis-specific CD8(+) T cells differentiated into either effector (CD127(lo) CD62L(lo)) or effector memory (CD127(hi) CD62L(lo)) cells, but not central memory cells (CD127(hi) CD62L(hi)), with low programmed death 1 (PD-1) expression, even in the presence of high levels of bacteria.
9082 24126533 Additionally, M. tuberculosis-specific CD8(+) and CD4(+) T cells produced substantial levels of tumor necrosis factor alpha (TNF-α) and gamma interferon (IFN-γ), but not interleukin 2 (IL-2), upon in vitro restimulation.
9083 24126533 Among M. tuberculosis-specific CD8(+) T cells, CD127(hi) effector memory cells displayed slower ongoing turnover but greater survival potential.
9084 24126533 However, the effector function of M. tuberculosis-specific CD8(+) CD127(hi) effector memory T cells was inferior to that of canonical CD8(+) CD127(hi) memory T cells generated after acute lymphocytic choriomeningitis virus infection.

9190 24337749 In this study, we investigated the expression and function of an inhibitory receptor, killer cell lectin-like receptor subfamily G member 1 (KLRG1), in the regulation of CD4(+) T cells and HBV vaccine responses during HCV infection.
9191 24337749 We demonstrated that KLRG1 was overexpressed on CD4(+) T cells from HCV-infected, HBV vaccine nonresponders compared with HBV vaccine responders.
9192 24337749 The capacity of CD4(+) T cells to proliferate and secrete IL-2 cytokine was inversely associated with the level of KLRG1 expression.
9193 24337749 Importantly, blocking KLRG1 signaling resulted in a significant improvement in CD4(+) T cell proliferation and IL-2 production in HCV-infected, HBV vaccine nonresponders in response to TCR stimulation.

9195 24337749 These results suggest that the KLRG1 pathway impairs CD4(+) T cell responses to neoantigen and induces a state of immune senescence in individuals with HCV infection, raising the possibility that blocking this negative-signaling pathway might improve HBV vaccine responses in the setting of chronic viral infection.

9267 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.
9268 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.
9269 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.
9270 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.
9271 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.
9272 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.
9273 24481607 Out of five male infants with T-B+NK- SCID phenotype, mutation analysis revealed interleukin-2 (common) gamma-chain receptor (IL2RG) mutations in 3 with positive X-linked family history, and Janus-kinase (JAK)-3 gene defects in the other two.
9274 24481607 Six patients had T-B-NK+ SCID phenotype and further 6 features of OS, 11 of which had recombinase-activating gene (RAG1or RAG2) and 1 Artemis gene mutations.
9275 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).
9276 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.

9279 24498941 Enzyme-linked immunosorbent spot was applied to determine the levels of IFN-γ, IL-2 and IL-4 secreted by splenic lymphocytes.
9280 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).
9281 24498941 Enzyme-linked immunosorbent spot was applied to determine the levels of IFN-γ, IL-2 and IL-4 secreted by splenic lymphocytes.
9282 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).
9283 24505407 The induction of a balanced Th1 and Th17 response, together with expression of effector cytokines, such as IFNG, IL2, IL17, IL21 and IL22, could be used as correlates of a protective host response.
9284 24516564 Prevention of intestinal allergy in mice by rflaA:Ova is associated with enforced antigen processing and TLR5-dependent IL-10 secretion by mDC.
9285 24516564 Using TLR5(-/-) mDC the rflaA:Ova induced IL-10 secretion was shown to be TLR5 dependent.
9286 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.
9287 24535711 In this study, we characterized a population of human differentiated effector CD4(+) T cells that is defined by low levels of the interleukin (IL)-2 and IL-7 receptors (CD25(-)CD127(-)).
9288 24535711 Notably, these CD25(-)CD127(-)CD4 T cells expressed effector markers such as CD244 and CD11b with low levels of CD27, contrasting with the memory phenotype dominating this population in healthy individuals.
9289 24535711 These cells did not cycle in patients, nor did they secrete IL-10 or IL-17, but instead displayed cytotoxic features.
9290 24535711 During neoadjuvant chemotherapy in patients with breast cancer, we found that the increase in CD25(-)CD127(-) CD4(+) T cells correlated with tumor regression.
9291 24565030 The immunological and clinical effects of mutated ras peptide vaccine in combination with IL-2, GM-CSF, or both in patients with solid tumors.
9292 24568545 Importantly, a single dose of Ad-H, with or without the addition of Ad expressing ovine granulocyte macrophage colony-stimulating factor and/or ovine interleukin-2, not only induced strong antibody and cell-mediated immunity but also completely protected goats against challenge with virulent PPRV, 4 months after vaccination.
9293 24574499 In chronic infection, dominant epitope-specific T cells developed a terminal differentiated KLRG1(+)/PD-1(lo) surface phenotype that was significantly reduced in the cryptic epitope-specific T cell populations.
9294 24574499 In contrast, cryptic epitope-specific CD4 T cells maintained significantly greater IFN-γ(+)TNF-α(+)IL-2(+) and TNF-α(+)IL-2(+) memory-associated polyfunctionality and enhanced proliferative capacity.
9295 24574499 Vaccine-associated IL-17A production by cryptic CD4 T cells was also enhanced, but without increased neutrophilia/pathology.
9296 24588000 When tested in cattle, MbΔp27-p55 did not induce IL-2 expression and induced a very low production of IFNγ, suggesting that the lack of P27/P55 reduces the capacity of M. bovis of triggering an adequate Th1 response.
9297 24598447 Fusion protein of mutant B7-DC and Fc enhances the antitumor immune effect of GM-CSF-secreting whole-cell vaccine.
9298 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.
9299 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.
9300 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.
9301 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.
9302 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.
9303 24598721 As expected, the RNA vaccine was clearly more effective than the protein vaccines in inducing a cellular immune response, as evaluated by the IgG2a/IgG1 ratio and synthesis of interferon gamma (IFNγ) and interleukin 2 (IL2).
9304 24602605 Immunization of mice with encapsulated M278 elicited higher M278-specific T-cell cytokines [Th1 (IFN-γ, IL-2), Th17 (IL-17)] and antibodies [Th1 (IgG2a), Th2 (IgG1, IgG2b)] compared to bare M278.
9305 24602605 Encapsulated-M278 mouse serum inhibited Chlamydia infectivity of macrophages, with a concomitant transcriptional down-regulation of MOMP, its cognate TLR2 and CD80 co-stimulatory molecule.
9306 24619696 Here we describe in detail the construction of a recombinant variant of FPV expressing the prostate tumor-associated antigen prostatic acid phosphatase (PAP) in conjunction with the immunostimulatory cytokine, interleukin-2 (IL-2), which, if undertaken under the appropriate regulatory conditions and with approvals in place, would theoretically be amenable to clinical trial applications.
9307 24629003 Mice immunized with BCG and then boosted with two intranasal immunizations with TB-RICs developed antigen-specific serum IgG antibody responses with mean end-point titres of 1 : 8100 (Acr) and 1 : 24 300 (Ag85B) and their splenocytes responded to in vitro stimulation by producing interferon gamma. 25% of CD4+ proliferating cells simultaneously produced IFN-γ, IL-2 and TNF-α, a phenotype that has been linked with protective immune responses in TB.
9308 24631092 Our results show that an optimum dose of adenovirus vector (2×10(7)pfu/mouse) administered intramuscularly (i.m.) induces high T cell proliferation, granzyme B-expressing CD8(+) T cells, pro-inflammatory cytokines such as IFN-γ, TNF-α, IL-2 and IL-6, and antibody responses that can significantly reduce the Vac-HCV viral load in the ovaries of female C57BL/6 mice.
9309 24648930 Immune responses were measured after immunization by anti-HBsAg, proliferation of splenocytes, the number of CD4+ and CD8+ molecules, CTL cytotoxicity, cytokines of IFN-γ and IL-2 secretion assays.
9310 24648930 Furthermore, pVAX1-L-GM plasmid increased the number of CD4+ and CD8+ molecules on the surface of the spleen T cell and the level of IFN-γ, IL-2 secretion. pVAX1-L-GM induced a specific immune response in mice and enhanced the immune effect.
9311 24648930 Immune responses were measured after immunization by anti-HBsAg, proliferation of splenocytes, the number of CD4+ and CD8+ molecules, CTL cytotoxicity, cytokines of IFN-γ and IL-2 secretion assays.
9312 24648930 Furthermore, pVAX1-L-GM plasmid increased the number of CD4+ and CD8+ molecules on the surface of the spleen T cell and the level of IFN-γ, IL-2 secretion. pVAX1-L-GM induced a specific immune response in mice and enhanced the immune effect.
9313 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).
9314 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.
9315 24662797 Increased levels of Th1 cytokines - IFN-γ, IL-2 and TNF-α are correlated with longer survival time without recurrence, whereas high levels of Th2 cytokines such as IL-10, predict unsuccessful BCG therapy.
9316 24682172 We have selected aptamers that specifically bind the murine receptor, DEC205, a C-type lectin expressed predominantly on the surface of CD8α(+) dendritic cells (DCs) that has been shown to be efficient at facilitating antigen crosspresentation and subsequent CD8(+) T cell activation.
9317 24682172 Using a minimized aptamer conjugated to the model antigen ovalbumin (OVA), DEC205-targeted antigen crosspresentation was verified in vitro and in vivo by proliferation and cytokine production by primary murine CD8(+) T cells expressing a T cell receptor specific for the major histocompatibility complex (MHC) I-restricted OVA257-264 peptide SIINFEKL.
9318 24682172 Compared with a nonspecific ribonucleic acid (RNA) of similar length, DEC205 aptamer-OVA-mediated antigen delivery stimulated strong proliferation and production of interferon (IFN)-γ and interleukin (IL)-2.
9319 24687086 To enhance vaccine efficacy, interleukin (IL)-2 was directed to predominantly memory phenotype CD8(+) T lymphocytes and natural killer (NK) cells via administration bound to anti-IL-2 monoclonal antibody clone S4B6 (IL-2S4B6).
9320 24687086 Notably, this dual regimen elicited large increases in both donor CD8(+) T and NK cells, but not CD4(+) T lymphocytes; the former 2 populations are essential for both vaccine efficacy and protection against opportunistic infections after HSCT.
9321 24690681 We report that ex-vivo exposure of quiescent or TCR-activated primary human T cells to thimerosal induced a dose-dependent apoptotic cell death associated with depolarization of mitochondrial membrane, generation of reactive oxygen species, cytochrome c release from the mitochondria and caspase-3 activation.
9322 24690681 Moreover, exposure to non-toxic concentrations of thimerosal induced cell cycle arrest in G0/G1 phase of TCR-activated T cells, and inhibition of the release of proinflammatory cytokines such as IFN gamma, IL-1 beta, TNF alpha, IL-2, as well as the chemokine MCP1.
9323 24690990 Immunization with a peptide containing MHC class I and II epitopes derived from the tumor antigen SIM2 induces an effective CD4 and CD8 T-cell response.
9324 24690990 Here, we sought to determine whether peptide vaccines designed harbor both class I as well as class II restricted antigenic motifs could concurrently induce CD4 and CD8 T cell activation against autologous tumor antigens.
9325 24690990 Immunization with a multi-epitope peptide harboring both MHC-I and MHC-II restricted epitopes induced an IFN-γ response in CD8 T cells to the HLA-A*0201-restricted SIM2(237-245) epitope, and an IL-2 response by CD4 T cells to the SIM2(240-254) epitope.
9326 24690990 Collectively, the data presented in this study suggest that a single peptide containing multiple SIM2 epitopes can be used to induce both a CD4 and CD8 T cell response, providing a peptide-based vaccine formulation for potential use in immunotherapy of various cancers.
9327 24699863 DCs were prepared from the mononuclear cells isolated from patients using IL-2/GM-CSF and loaded with tumor antigens; CIK cells were prepared by incubating peripheral blood lymphocytes with IL-2, IFN-γ, and CD3 antibodies.
9328 24706270 Concerning this point, the recent studies suggest the concept of immune exhaustion of CD8 T cells, characterized by their decreased production of IL-2, TNFα, and IFNγ even after antigen stimulation.
9329 24706270 The identification of immune effector and/or exhausted CD8 T cells by monitoring multiple parameters including T cell exhaustion markers such as PD-1 and Tim-3 and intracellular cytokines is, therefore, crucial to understand the real-time, ongoing immune status.
9330 24706270 By stimulation of PBMCs with PMA/ionomycin for 6 h, more than 1-2 % of total CD8 T cells are identified as positive in terms of multifunctionality, thus producing multiple cytokines--IL-2, TNFα, and IFNγ--at single-cell level in case of all healthy donors.

9334 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).
9335 24718267 In contrast, no demyelination was detected in the ONs of myelin basic protein (MBP)- and proteolipid protein (PLP)-injected mice.
9336 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.
9337 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.
9338 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.

9354 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.
9355 24731807 Furthermore, HAC1 induced a local T-cell response demonstrated by elevated IL-2 and IFN-γ levels in PCLS of c-di-GMP-vaccinated mice upon re-stimulation.
9356 24738054 A recombinant mutant HPV16 E7 (rE7m) protein was mixed with lipo-Nter to immunize the mice; the anti-E7 antibody titers were increased, and the T helper cells were skewed toward the Th1 fate (increased IL-2 and decreased IL-5 secretion).
9357 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.
9358 24755922 We found that our strategy is significantly more potent than multiple TALE activators alone in activating expression of IL-2 and GM-CSF in diverse cell origins in which both genes are otherwise completely silenced.
9359 24787274 The samples were extensively characterized for the ability of T cell subsets to respond to recall viral antigens including cytomegalovirus, Epstein-Barr virus, influenza virus, and HIV-1 using Interferon-gamma (IFN-γ) enzyme linked immunospot (ELISpot) and IFN-γ/interleukin 2 (IL-2) intracellular cytokine staining (ICS) assays.
9360 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.
9361 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.
9362 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.
9363 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.
9364 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.
9365 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.

9367 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.
9368 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.
9369 24789782 The data obtained with overlapping peptides in interleukin-2 (IL-2) enzyme-linked immunosorbent spot (ELISpot) assays were analyzed in relation to the three-dimensional structures of the capsid (C) and E proteins as well as to epitope predictions based on major histocompatibility complex (MHC) class II peptide affinities.
9370 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.
9371 24789795 However, IL-4 and IL-10 were not produced in the vaccinated mice.
9372 24801479 Each panel includes a de-identified commercial Luminex assay kit with standards to quantify human IFNγ, TNFα, IL-6, IL-10 and IL-2, and a series of recombinant cytokine-spiked human serum samples.
9373 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.
9374 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).
9375 24860188 Differential impact of CD27 and 4-1BB costimulation on effector and memory CD8 T cell generation following peptide immunization.
9376 24860188 In this study, we analyzed the CD8 T cell response elicited by two experimental vaccines comprising a peptide/protein Ag and an agonist that delivers a costimulatory signal via CD27 or 4-1BB.
9377 24860188 CD27 agonists promoted increased expression of perforin and the generation of short-lived memory cells, whereas stimulation with 4-1BB agonists favored generation of stable memory.
9378 24860188 The memory-promoting effects of 4-1BB were independent of CD4 T cells and were the result of programing within the first 2 d of priming.
9379 24860188 Consistent with this conclusion, CD27 and 4-1BB-stimulated CD8 T cells expressed disparate amounts of IL-2, IFN-γ, CD25, CD71, and Gp49b as early as 3 d after in vivo activation.
9380 24860188 In addition, memory CD8 T cells, generated through priming with CD27 agonists, proliferated more extensively than did 4-1BB-generated memory cells, but these cells failed to persist.
9381 24875318 On days 7, 14, 21, 28, 35 and 42 after the first vaccination, the lymphocyte proliferation, serum antibody titer and interleukin-2 (IL-2) and interferon-gamma (IFN-γ) were measured.
9382 24877765 CAF09 was superior in its ability to induce antigen-specific CD8+ T cells as compared to other previously described CTL-inducing adjuvants, CAF05 (DDA/trehalose dibehenate (TDB)/Poly(I:C)), Aluminium/monophosphoryl lipid-A (MPL) and Montanide/CpG/IL-2.
9383 24877765 The CD4+ T cells induced by CAF09 were mainly of an effector-memory-like phenotype and the CD8+ T cells were highly cytotoxic.
9384 24878070 The populations of CD4, CD8, and TCR γδ T-cells in immunized chickens were significantly greater than in the controls.
9385 24878070 Increased levels of IFN-γ, IL-2, IL-6 and IL-10 were observed in peripheral blood mononuclear cells stimulated with SE specific antigen.
9386 24878070 After virulent SE challenge, the immune system of immunized chickens was rapidly stimulated, as indicated by significantly increased population of CD4 and CD8 T-cells.
9387 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.
9388 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.
9389 24898077 However, IL-18 protein lacks a typical signal sequence and requires cleavage into its mature active form by caspase 1.

9406 24912383 The results showed that heat stress induced the upregulation of cortisol in the plasma of pigs (P<0.05); TLR4 mRNA was elevated, but IL-2 was reduced in peripheral blood mononuclear cells (PBMC, P<0.05).
9407 24912383 In the in vitro model (PBMC heat shocked for 1 h followed by a 9 h recovery period), TLR2 and TLR4 mRNA expression also increased, as did the concentration of IL-12 in supernatants.
9408 24912383 We concluded that a consecutive heat stress period elevated the expression of TLR2 and TLR4 in PBMC and increased the plasma levels of inflammatory cytokines.

9413 24926294 In addition, the vaccine induced CD4(+) and CD8(+) T cells producing IFN-γ, IL-2, and TNF-α, and targeting the DENV-2 NS1, NS3, and NS5 proteins.
9414 24926294 Moreover, vaccine-specific T cells were cross-reactive with the non-structural NS3 and NS5 proteins of DENV-4.
9415 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.
9416 24945624 Relative to BCG-GFP, BCG-TB1860 effected a significant near total reduction both in secretion of cytokines IL-2, IL-12p40, IL-12p70, TNF-α, IL-6 and IL-10, and up regulation of co-stimulatory molecules MHC-II, CD40, CD54, CD80 and CD86 by infected bone marrow derived dendritic cells (BMDC), while leaving secreted levels of TGF-β unchanged.
9417 24945624 Splenocytes from mice infected with BCG-SSI showed significantly less proliferation and secretion of IL-2, IFN-γ and IL-17, but secreted higher levels of IL-10 in response to in vitro restimulation with BCG-TB1860 compared to BCG-GFP.

9426 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.
9427 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.
9428 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).

9441 24966857 The multiparameter flow cytometry analysis was used to assess the immune response after immunotherapy and disclosed that the degree of the immunotherapeutic effect is predicted by the frequencies of the CD4(+) and CD8(+) T cells producing IL-2 or TNF-α or both.
9442 24966857 Collectively, our multifunctional analysis disclosed that immunotherapeutic protection improved as the CD4 responses progressed from 1+ to 2+, in the case of the F1 and F3 vaccines, and as the CD8 responses changed qualitatively from 1+ to 3+, mainly in the case of the F1 vaccine, providing new correlates of immunotherapeutic protection against cutaneous leishmaniasis in mice based on T-helper TH1 and CD8(+) mediated immune responses.
9443 24967273 The circulating interleukin-(IL-)10 and interferon-(IFN-) γ concentrations were significantly higher in the vitamin D sufficient athletes.

9446 24973616 In an aggressive B16-F10 murine melanoma model, we evaluated the effectiveness and antitumor mechanisms triggered by a surgery adjuvant treatment that combined a local suicide gene therapy (SG) with a subcutaneous genetic vaccine (Vx) composed of B16-F10 cell extracts and lipoplexes carrying the genes of human interleukin-2 and murine granulocyte and macrophage colony stimulating factor.
9447 24980867 The results demonstrated that Ad5-CEAB elicited a strong antigen-specific immune response, particularly of the Th1 immune responses that were characterized by an increased ratio of IgG2a/IgG1 and secretions of Th1 type cytokines, IFN-γ, TNF-α, IL-2 and IL-12.
9448 24989432 We previously reported that altered peptide ligands (APLs) of type II collagen (CII256-271) suppress the development of collagen-induced arthritis (CIA).
9449 24989432 These effects were mediated by the induction of IL-10 from CD4(+ ) CD25(-) T cells against CII antigen in splenocytes and inguinal lymph nodes (iLNs), and treatment of APL had no effect on the production of IFN-γ, IL-17, IL-2 or Foxp3(+) Treg cells.
9450 24992314 The frequencies of IFNγ+IL2+TNFα+ PPD-specific CD4+CD45RO+ T-cells correlate with the magnitude of the QuantiFERON® gold in-tube response in a prospective study of healthy indian adolescents.
9451 24995010 A dominant effector memory T (TEM) phenotype was observed in gastric LPMC CD4(+) and CD8(+) T cells in all age groups.
9452 24995010 We then evaluated whether these cells represented a population of gastric tissue-resident memory T (TRM) cells by assessing expression of CD103 and CD69.
9453 24995010 The vast majority of gastric LPMC CD8(+) T cells either co-expressed CD103/CD69 (>70%) or expressed CD103 alone (~20%).
9454 24995010 Gastric LPMC CD4(+) T cells also either co-expressed CD103/CD69 (>35%) or expressed at least one of these markers.
9455 24995010 Thus, gastric LPMC CD8(+) and CD4(+) T cells had the characteristics of TRM cells.
9456 24995010 Gastric CD8(+) and CD4(+) TRM cells produced multiple cytokines (IFN-γ, IL-2, TNF-α, IL-17A, MIP-1β) and up-regulated CD107a upon stimulation.
9457 24995010 Furthermore, gastric CD8(+) TRM and CD4(+) TRM cells demonstrated differences in the frequency, susceptibility to activation, and cytokine/multi-cytokine production profiles among the age groups.
9458 25000334 The data showed that the antibody titers against OmpA, the concentration of IL-2, CD4 +, and CD8 +, T lymphocyte proliferation rate in Group II were significantly higher (P < 0.05) than those in the other groups, little difference in SIgA content was observed among groups I to VI.

9496 25024382 Development of a vaccine against pulmonary tuberculosis may require immunization strategies that induce a high frequency of Ag-specific CD4 and CD8 T cells in the lung.
9497 25024382 In contrast, aerosolized AERAS-402 alone or following BCG induced potent and stable Ag85A/b-specific CD4 and CD8 effector T cells in bronchoalveolar lavage that largely produced IFN-γ, as well as TNF and IL-2.
9498 25035957 Nucleoprotein (NP)-specific CD8(+) T cells encountered antigen on CD40-licensed, CD70-expressing, CD103(-)CD11b(hi) dendritic cells (DCs) at later times in the primary response.
9499 25035957 As a consequence, they maintained CD25 expression and responded to interleukin-2 (IL-2) and CD27, which together programmed their robust secondary proliferative capacity and interferon-γ (IFN-γ)-producing ability.
9500 25035957 In contrast, polymerase (PA)-specific CD8(+) T cells did not encounter antigen-bearing, CD40-activated DCs at later times in the primary response, did not receive CD27 and CD25 signals, and were not programmed to become memory CD8(+) T cells with strong proliferative and cytokine-producing ability.
9501 25042008 Vaccination increased: (i) the breadth of the immune response from 1 (1-3) to 4 (2-5) peptide-pool responses/patient (p = 0.009); (ii) the frequency of functional T cells (producing at least two cytokines among IFN-γ, TNF-α, and IL-2) from 0.026 to 0.32% (p = 0.002) and from 0.26 to 0.35% (p = 0.005) for CD4(+) and CD8(+) T cells, respectively; and (iii) the breadth of cytokines secreted by PBMCs upon antigen exposure, including IL-2, IFN-γ, IL-21, IL-17, and IL-13.
9502 25042008 An inverse correlation was found between the maximum of VL and the frequency of polyfunctional CD4(+) T cells (p = 0.007), production of IL-2 (p = 0.006), IFN-γ (p = 0.01), IL-21 (p = 0.006), and IL-13 (p = 0.001).

9504 25042008 An inverse correlation was found between the maximum of VL and the frequency of polyfunctional CD4(+) T cells (p = 0.007), production of IL-2 (p = 0.006), IFN-γ (p = 0.01), IL-21 (p = 0.006), and IL-13 (p = 0.001).
9505 25052754 Cytokines IL-2, IL-8 and TNF-α appear to be essential for effective BCG therapy and nonrecurrence, while IL-10 may have an inhibitory effect on BCG responses.
9506 25052754 IL-2, IL-8, TRAIL and TNF-α are potentially predictive of response to BCG.
9507 25052754 Cytokines IL-2, IL-8 and TNF-α appear to be essential for effective BCG therapy and nonrecurrence, while IL-10 may have an inhibitory effect on BCG responses.
9508 25052754 IL-2, IL-8, TRAIL and TNF-α are potentially predictive of response to BCG.
9509 25101086 We here report optimal γδT cell expansion (>10(7) cells/ml blood) when peripheral blood mononuclear cells (PBMC) from healthy individuals and melanoma patients were stimulated with zoledronate and then cultured for 14 days in the presence of IL-2 and IL-15, yielding γδT cell cultures of variable purity (77 ± 21 and 56 ± 26%, respectively).
9510 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.
9511 25131774 IL-10 and IL-12 were upregulated in group V-/C+E+, IL-10 also in group V+/C+E+ (SD 40) while IL-2 expression remained unaltered.
9512 25141829 Treatment with IL-17A/IL-17F or IL-22 expanded phosphoantigen 4-hydroxy-3-methyl-but-enyl pyrophosphate (HMBPP)-stimulated Vγ2Vδ2 T cells from BCG-vaccinated macaques but not from naïve animals, and IL-23 induced greater expansion than the other Th17-related cytokines.
9513 25141829 Consistently, Mtb infection of macaques also enhanced the ability of IL-17/IL-22 or IL-23 to expand HMBPP-stimulated Vγ2Vδ2 T cells.
9514 25141829 When evaluating IL-23 signaling as a prototype, we found that HMBPP/IL-23-expanded Vγ2Vδ2 T cells from macaques infected with Mtb or vaccinated with BCG or Listeria ΔactA prfA*-ESAT6/Ag85B produced IL-17, IL-22, IL-2, and IFN-γ.
9515 25141829 Furthermore, HMBPP/IL-23-induced proliferation of Vγ2Vδ2 T cells appeared to require APC contact and involve the conventional and novel protein kinase C signaling pathways.
9516 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.
9517 25150134 Depletion of NKp46-expressing cells revealed that 80% of the killing induced by IL-2 could be attributed to NKp46(+) cells.
9518 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.
9519 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.
9520 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.
9521 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.
9522 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.
9523 25152895 The results showed that rBCG strains overexpressing Ag856A2 at differential levels induced different antigen-specific IFN-γ production and comparable number of M. tb-specific CD4 T cells expressing IL-2.
9524 25153350 Our previous study demonstrated that the extracellular domain of murine BTLA (the soluble form of BTLA) can facilitate HSP70 vaccine-triggered antitumor immunity by blocking BTLA-HVEM interactions in a murine TC-1 non-metastatic tumor model.
9525 25153350 Furthermore, the Th1 cytokines IL-2 and IFN-γ were up-regulated, while the negative regulatory molecules IL-10 and TGF-β were down-regulated.
9526 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.
9527 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).
9528 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.
9529 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).
9530 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.
9531 25174880 Besides, IFN-DCs and IL4-DCs equally induced apoptosis of activated CD4(+) and CD8(+) T cells.
9532 25185668 Moreover, cytokine assays indicated that vaccination of Ad-SjIAP significantly increased the production of interferon (IFN)-γ and IL-2 as compared to the corresponding control group.
9533 25197078 Further investigation demonstrated that Ad5-specific CD4 T cells selectively display a proinflammatory Th17-like phenotype and express macrophage inflammatory protein 3α and α4β7 integrin, suggestive of gut mucosa homing potential of these cells.
9534 25197078 Analysis of HIV p24 and cytokine coexpression using flow cytometry revealed preferential infection of IL-17- and IL-2-producing, Ad5-specific CD4 T cells by HIV in vitro.
9535 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.
9536 25206904 In the Aβ42 group, levels of IL-4, IL-10, IL-2 and interferon-γ were all increased.
9537 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.
9538 25206904 In the Aβ42 group, levels of IL-4, IL-10, IL-2 and interferon-γ were all increased.
9539 25217614 IFN-γ, IL-2, inducible nitric oxide synthase and nitric oxide were strongly induced by SH infection, and may be associated with the pathogenicity of the SH strain.
9540 25217614 IFN-α, IFN-β, IFN-stimulated transmembrane protein 1, IFN-stimulated gene 12, 2',5'-oligoadenylate synthetase-like and IL-6 were moderately induced by SH infection at 24 h p.i., and dramatically induced by FC64 infection at 36 h p.i.
9541 25225461 We show that the functional impairment of CD4 T cells, including the reduced capacity to proliferate and to produce IFN-γ and IL-2, was restricted to bacteria-specific and not virus-specific CD4 T cells.
9542 25225461 Of note, endotoxemia was associated with significantly higher expression of programmed death 1 (PD-1) on CD4 T cells.
9543 25225461 The blockade of the PD-1-PD-L1/2 axis in vitro restored CD4 T cell proliferation capacity, thus indicating that PD-1 signaling negatively regulates CD4 T cell functions.
9544 25225461 Finally, we showed that intravenous immunoglobulin G (IVIG) treatment significantly reduced endotoxemia and the percentage of PD-1(+) CD4 T cells, and restored bacteria-specific CD4 T cell cytokine production and proliferation.
9545 25240755 PLA-p24 captured by MDDCs from HIV-1 individuals induced a slight degree of MDDC maturation, cytokine and chemokine secretion and migration towards a gradient of CCL19 chemokine and highly increased HIV-specific CD8(+) T-cell proliferation compared with p24 alone.
9546 25240755 After complete maturation induction of PLA-p24-pulsed MDDCs, maximal migration towards a gradient of CCL19 chemokine and induction of HIV-specific T-cell proliferation (two-fold higher for CD4(+) than CD8(+)) and cytokine secretion (IFN-γ and IL-2) in the co-culture were observed.
9547 25240755 MDDCs infected with MVA-gag and MVA-gag trans-membrane were able to induce HIV-specific CD8(+) proliferation and secretion of IFN-γ, IL-2, IL-6 and TNF-α.
9548 25240755 PLA-p24 captured by MDDCs from HIV-1 individuals induced a slight degree of MDDC maturation, cytokine and chemokine secretion and migration towards a gradient of CCL19 chemokine and highly increased HIV-specific CD8(+) T-cell proliferation compared with p24 alone.
9549 25240755 After complete maturation induction of PLA-p24-pulsed MDDCs, maximal migration towards a gradient of CCL19 chemokine and induction of HIV-specific T-cell proliferation (two-fold higher for CD4(+) than CD8(+)) and cytokine secretion (IFN-γ and IL-2) in the co-culture were observed.
9550 25240755 MDDCs infected with MVA-gag and MVA-gag trans-membrane were able to induce HIV-specific CD8(+) proliferation and secretion of IFN-γ, IL-2, IL-6 and TNF-α.
9551 25250027 TLR2 Signaling is Required for the Innate, but Not Adaptive Response to LVS clpB.
9552 25250027 We sought to determine whether TLR2 signaling was required during the immune response to LVS clpB.
9553 25250027 TLR2 knock-out (TLR2 KO) mice previously infected with LVS clpB are completely protected during a lethal challenge with LVS.
9554 25250027 Furthermore, the kinetics and magnitude of the primary T-cell response in B6 and TLR2 KO mice are similar indicating that TLR2 signaling is dispensable for the adaptive immune response to LVS clpB.
9555 25250027 TLR2 signaling was important, however, for the innate immune response to LVS clpB.
9556 25250027 IL-1α, IL-1β, IL-2, IL-17, MIP-1α, and TNF-α production depended on TLR2 signaling, while GM-CSF, IFN-γ, and VEGF production were completely independent of TLR2 signaling.
9557 25250027 IL-6, IL-12, IP-10, KC, and MIG production were partially dependent on TLR2 signaling.
9558 25250027 Together our data indicate that the innate immune response to LVS clpB requires TLR2 signaling for the maximal innate response, whereas TLR2 is not required for the adaptive immune response.
9559 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.
9560 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.
9561 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.
9562 25267176 The expression levels of granzyme K and CD8 in DNA-vaccinated chickens were significantly (p < 0.05) higher than those in unvaccinated chickens upon IBDV challenge at 0.5 or 1 dpc.
9563 25267176 Bursal transcripts related to innate immunity and inflammation, including TLR3, MDA5, IFN-α, IFN-β, IRF-1, IRF-10, IL-1β, IL-6, IL-8, iNOS, granzyme A, granzyme K and IL-10, were upregulated or significantly (p < 0.05) upregulated at 3 dpc and later in unvaccinated chickens challenged with IBDV.
9564 25267176 The expression levels of genes related to immune cell regulation, apoptosis and glucose transport, including CD4, CD8, IL-2, IFN-γ, IL-12(p40), IL-18, GM-CSF, GATA-3, p53, glucose transporter-2 and glucose transporter-3, were upregulated or significantly (p < 0.05) upregulated at 3 dpc and later in unvaccinated chickens challenged with IBDV.
9565 25267176 Taken together, the results indicate that the bursal transcriptome involved in innate immunity, inflammation, immune cell regulation, apoptosis and glucose transport, except for granzyme K and CD8, was not differentially expressed in DNA-vaccinated chickens protected from IBDV challenge.
9566 25268976 The levels of T-lymphocyte proliferation in piglets immunized with pBudCE4.1-ORF2/IL18 were significantly higher than in those immunized with pBudCE4.1-ORF2, and pBudCE4.1-ORF2/IL18 stimulated a significantly increased production of IFN-γ and IL-2.
9567 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.
9568 25282449 BLP significantly promoted growth and expansion of natural killer cells and of CD4(+) and CD8(+) T-cell subsets in the spleen.
9569 25308358 Th1-type cytokines including IL-1, IL-2, IL-12 and granulocyte-macrophage colony-stimulating factor are potent stimulators of Th1 differentiation and Th1-based antitumor response.
9570 25343523 Murine granulocyte-macrophage colony-stimulating factor expressed from a bicistronic simian immunodeficiency virus-based integrase-defective lentiviral vector does not enhance T-cell responses in mice.
9571 25343523 As a prelude to immunization studies in nonhuman primates, we compared in mice the immunogenicity of a simian immunodeficiency virus (SIV)-based integrase (IN)-defective lentiviral vector (IDLV) encoding the model antigen-enhanced green fluorescence protein (eGFP) in the presence or absence of the murine granulocyte-macrophage colony-stimulating factor (mGM-CSF) expressed from an internal ribosomal entry site (IRES) sequence.
9572 25343523 Results indicated that the mGM-CSF was unable to improve the magnitude and quality of the immune response against the eGFP transgene in the context of the SIV-based IDLV, as evaluated by enzyme-linked immunosorbent spot (ELISPOT) assays for interferon-γ (IFN-γ) and by intracellular cytokine staining for IFN-γ, interleukin-2 (IL-2), and tumor necrosis factor-alpha (TNF-α).
9573 25348693 Although no significant difference in splenic CD4+ T cell proliferation was observed among all groups of vaccinated mice, splenocytes from mice vaccinated with two antigens exhibited higher interferon-γ and IL-2 production than when using single antigens alone upon in vitro restimulation.
9574 25378595 M2-specific CD4 T cells were selectively cytotoxic, produced multiple antiviral cytokines, and sustained IL-2 production.
9575 25399820 The results showed that pcAmIL-18 remarkably improved the level of specific antibody, IFN-γ and IL-2 in mice sera, the T lymphocyte proliferation index and the percentage of CD4(+) and CD8(+) cells.
9576 25419982 In this study, we correlated the longitudinal changes in the magnitude and functional quality of CD4(+) and CD8(+) T-cell response over a period of two years after mucosal or parenteral BCG vaccination with the strength of protection against Mycobacterium tuberculosis in mice.
9577 25419982 The BCG vaccination-induced CD4(+) and CD8(+) T cells exhibited comparable response kinetics but distinct functional attributes in-terms of IFN-γ, IL-2 and TNF-α co-production and CD62L memory marker expression.
9578 25419982 The progressive decline in the multifactorial functional abilities of CD4(+) and CD8(+) T cells in-terms of type-1 cytokine production, proliferation and cytolytic potential corresponded with the waning of protection against M. tuberculosis infection.
9579 25419982 In addition, simultaneous increase in the dysfunctional and terminally-differentiated T cells expressing CTLA-4, KLRG-1 and IL-10 during the contraction phase of BCG-induced response coincided with the loss of protection.
9580 25448107 This protection correlated with the accumulation of CD4(+) T cells expressing IL-17(+)TNF(+)IL-2(+).
9581 25448107 In contrast, mice challenged with Mtb 21 days after BCG vaccination exhibited only a mild and transient protection, associated with the accumulation of CD4(+) T cells that were mostly IFN-γ(+)TNF(+) and to a lesser extent IFN-γ(+)TNF(+)IL-2(+).
9582 25448107 This protection correlated with the accumulation of CD4(+) T cells expressing IL-17(+)TNF(+)IL-2(+).
9583 25448107 In contrast, mice challenged with Mtb 21 days after BCG vaccination exhibited only a mild and transient protection, associated with the accumulation of CD4(+) T cells that were mostly IFN-γ(+)TNF(+) and to a lesser extent IFN-γ(+)TNF(+)IL-2(+).
9584 25450885 During the monitoring period, the indices of immune organ weight, lymphocyte transformation rates, CD4(+) and CD8(+) T-lymphocyte counts in peripheral blood, IL-2 and IFN-γ secretions, serum antibody titers of ND vaccine, and viral loads in spleens were determined.
9585 25453291 In vivo test, 14-day-old chickens vaccinated with ND vaccine were injected respectively with sAMP(9) and AMP, the peripheral lymphocytes proliferation, serum antibody titer, IFN-γ, IL-2 and IL-6 contents were determined.
9586 25453291 The results displayed that the sAMP could significantly promote lymphocyte proliferation and elevate the antibody titers and content of IFN-γ, IL-2 and IL-6 in comparison with unmodified AMP.
9587 25453291 In vivo test, 14-day-old chickens vaccinated with ND vaccine were injected respectively with sAMP(9) and AMP, the peripheral lymphocytes proliferation, serum antibody titer, IFN-γ, IL-2 and IL-6 contents were determined.
9588 25453291 The results displayed that the sAMP could significantly promote lymphocyte proliferation and elevate the antibody titers and content of IFN-γ, IL-2 and IL-6 in comparison with unmodified AMP.
9589 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.
9590 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.
9591 25467292 In both lung and spleen, BALB/c cells produced at least 2-fold more IFN-γ, and up to 7-fold more IL-2 and IL-17 than C57BL/6 cells, whereas IL-10 production was reciprocally increased in C57BL/6 mice.
9592 25471322 Different individuals who were immunized with a virosome vaccine comprising influenza antigens combined with P. falciparum antigens, demonstrated pre-existing interferon-γ, IL-2 and IL-5 ELIspot responses against the influenza antigens, and showed boosting of anti-influenza T-cell responses only for IL-5.
9593 25474358 Significantly increased percentages of CD4+ and CD8+ T cells producing IFN-γ in spleen of vaccinated animals were observed in comparison to control group by flow cytometric analysis.
9594 25474358 A significant difference was observed in the expression of IL-2, IFN-γ, TNF-α, and CD4+/CD8+ T cells secreting IFN-γ in the F1+LcrV+HSP70(II) vaccinated group in comparison to the F1+LcrV vaccinated group.
9595 25483519 Interestingly, hCD46tg and wt black/6 mice showed a predominant CD4(+) T-cell response against MV-N, whereas IFNARCD46tg mice developed both, CD4(+) and CD8(+) T-cell response against MV-N.
9596 25483519 Analysis of the cytokine profile of MV-N specific CD4(+) T-cells and transgene (SIVgag) specific CD8(+) T-cells revealed qualitative differences of the T-cell responses; noticeably a significant reduction of the frequency of CD4(+)IL-2(+) expressing cells in IFNARCD46tg mice as compared with hCD46tg or wt black/6 mice.
9597 25483636 After 48 hours, CD4+ and CD8+ T cells were harvested from both groups and stained for PD-1/CD25/ FOXP3.
9598 25483636 Similarly, in terms of PD-1 expression and Treg cells (CD4+/CD25high(+)/FOXP3+), only the HD group showed higher levels in CD4 lymphocytes.
9599 25483636 In terms of cytokines, the HD group showed higher levels of Th1 (IL-2/TNF-α/IFN-γ) and regulatory (IL-10) profiles, with monocytes, but not Tr1 cells, acting as the main source of IL-10.
9600 25483691 Comparing CD4+ T cell cytokine responses at month 12, there was a trend of increased levels of IL-2 and TNF-α in the Cervarix® groups versus the Gardasil® groups that was consistent across all 4 tested HPV types (16/18/33/45).
9601 25487886 Enhanced Th1-biased immune efficacy of porcine circovirus type 2 Cap-protein-based subunit vaccine when coadministered with recombinant porcine IL-2 or GM-CSF in mice.
9602 25487886 Interleukin 2 (IL-2) and granulocyte-macrophage colony-stimulating factor (GM-CSF), used as immune adjuvants, have been shown to enhance the immunogenicity of certain antigens or vaccines in various experimental models.
9603 25487886 Furthermore, the PCV2-Cap + PoIL-2, Cap-PoGM-CSF, and PCV2-Cap + PoGM-CSF vaccines elicited stronger lymphocyte proliferative responses and greater IL-2 and interferon gamma (IFN-γ) secretion.
9604 25487886 Enhanced Th1-biased immune efficacy of porcine circovirus type 2 Cap-protein-based subunit vaccine when coadministered with recombinant porcine IL-2 or GM-CSF in mice.
9605 25487886 Interleukin 2 (IL-2) and granulocyte-macrophage colony-stimulating factor (GM-CSF), used as immune adjuvants, have been shown to enhance the immunogenicity of certain antigens or vaccines in various experimental models.
9606 25487886 Furthermore, the PCV2-Cap + PoIL-2, Cap-PoGM-CSF, and PCV2-Cap + PoGM-CSF vaccines elicited stronger lymphocyte proliferative responses and greater IL-2 and interferon gamma (IFN-γ) secretion.
9607 25487886 Enhanced Th1-biased immune efficacy of porcine circovirus type 2 Cap-protein-based subunit vaccine when coadministered with recombinant porcine IL-2 or GM-CSF in mice.
9608 25487886 Interleukin 2 (IL-2) and granulocyte-macrophage colony-stimulating factor (GM-CSF), used as immune adjuvants, have been shown to enhance the immunogenicity of certain antigens or vaccines in various experimental models.
9609 25487886 Furthermore, the PCV2-Cap + PoIL-2, Cap-PoGM-CSF, and PCV2-Cap + PoGM-CSF vaccines elicited stronger lymphocyte proliferative responses and greater IL-2 and interferon gamma (IFN-γ) secretion.
9610 25520147 The CD4 T cell cytokine response (IFN-γ, interleukin-2 [IL-2], interleukin-17A [IL-17A], interleukin-22 [IL-22], granulocyte-macrophage colony-stimulating factor [GM-CSF], and tumor necrosis factor alpha [TNF-α]) and surface marker expression (CD27, CXCR3, and CD154) were then measured.
9611 25520147 We found that the proportion of PPD-specific CD4 T cells, defined as CD154(+) TNF-α(+) cells that were negative for CD27 and positive for GM-CSF, gave the strongest discrimination between subjects with latent and those with active TB (area under the receiver operator characteristic [ROC] curve of 0.9277; P < 0.0001).
9612 25520147 Also, the proportions and absolute numbers of HBHA-specific CD4 T cells were significantly higher in those with latent TB infection, particularly CD154(+) TNF-α(+) IFN-γ(+) IL-2(+) and CD154(+) TNF-α(+) CXCR3(+).
9613 25520147 The CD4 T cell cytokine response (IFN-γ, interleukin-2 [IL-2], interleukin-17A [IL-17A], interleukin-22 [IL-22], granulocyte-macrophage colony-stimulating factor [GM-CSF], and tumor necrosis factor alpha [TNF-α]) and surface marker expression (CD27, CXCR3, and CD154) were then measured.
9614 25520147 We found that the proportion of PPD-specific CD4 T cells, defined as CD154(+) TNF-α(+) cells that were negative for CD27 and positive for GM-CSF, gave the strongest discrimination between subjects with latent and those with active TB (area under the receiver operator characteristic [ROC] curve of 0.9277; P < 0.0001).
9615 25520147 Also, the proportions and absolute numbers of HBHA-specific CD4 T cells were significantly higher in those with latent TB infection, particularly CD154(+) TNF-α(+) IFN-γ(+) IL-2(+) and CD154(+) TNF-α(+) CXCR3(+).
9616 25549696 Multiparameter flow cytometry revealed that F16 induced significantly more polyfunctional antigen-specific CD8+ T cells simultaneously producing IFN-γ, IL-2, and TNF-α than other test formulations.
9617 25563963 The results showed that OPL could significantly promote the phagocytosis of macrophages and induce the secretion of IL-2 and IL-6 in vitro; OPL at high and medium doses could significantly improve the phagocytosic index, promote lymphocyte proliferation, increase the proportion of T lymphocyte subpopulations (CD4(+) and CD8(+)), enhance antibody titer and improve the protective rate in vivo.
9618 25574771 In the present study, the kinetics of IL-2, IL-4 and IFN-γ expression was determined in bovine PBMCs by real-time PCR and in whole blood by cytokine-release assay after in vitro stimulation with recall foot-and-mouth disease virus (FMDV) antigen.
9619 25574771 The results showed that the cytokine mRNA of IL-2 and IFN-γ in PBMCs were induced early (peak induction at 6 h), whereas the IL-4 mRNA showed delayed induction (peaked at 24 h).
9620 25574771 The peak accumulation of cytokine protein in whole blood was recorded at 72 h for IL-2 and IL-4, and 96 h for IFN-γ.
9621 25574771 In the present study, the kinetics of IL-2, IL-4 and IFN-γ expression was determined in bovine PBMCs by real-time PCR and in whole blood by cytokine-release assay after in vitro stimulation with recall foot-and-mouth disease virus (FMDV) antigen.
9622 25574771 The results showed that the cytokine mRNA of IL-2 and IFN-γ in PBMCs were induced early (peak induction at 6 h), whereas the IL-4 mRNA showed delayed induction (peaked at 24 h).
9623 25574771 The peak accumulation of cytokine protein in whole blood was recorded at 72 h for IL-2 and IL-4, and 96 h for IFN-γ.
9624 25574771 In the present study, the kinetics of IL-2, IL-4 and IFN-γ expression was determined in bovine PBMCs by real-time PCR and in whole blood by cytokine-release assay after in vitro stimulation with recall foot-and-mouth disease virus (FMDV) antigen.
9625 25574771 The results showed that the cytokine mRNA of IL-2 and IFN-γ in PBMCs were induced early (peak induction at 6 h), whereas the IL-4 mRNA showed delayed induction (peaked at 24 h).
9626 25574771 The peak accumulation of cytokine protein in whole blood was recorded at 72 h for IL-2 and IL-4, and 96 h for IFN-γ.
9627 25576595 The inducible costimulator (ICOS) plays a key role in the development of Th17 cells, but its role in the development and antitumor activity of IL-17-producing CD8(+) T cells (Tc17) remains unknown.
9628 25576595 However, ICOS stimulation did not augment the antitumor activity of IL-2 expanded T cells.
9629 25576595 Additional investigation revealed that ICOS stimulation not only increased IL-2Rα, CXCR3, and IL-23R expression on Tc17 cells, but also dampened their expression of suppressive molecule CD39.
9630 25576595 Although Tc17 cells activated with an ICOS agonist cosecreted heightened IL-17A, IL-9, and IFN-γ, their therapeutic effectiveness was critically dependent on IFN-γ production.
9631 25576595 Depletion of IL-17A and IL-9 had little impact on antitumor Tc17 cells activated with an ICOS agonist.
9632 25589549 Gamma interferon (IFN-γ) produced by CD4(+) T cells and, recently, multifunctional CD4(+) T cells secreting IFN-γ, tumor necrosis factor (TNF), and interleukin-2 (IL-2) have been used in vaccine studies as a measurable immune parameter, reflecting activity of a vaccine and potentially predicting protection.
9633 25589549 However, accumulating experimental evidence suggests that host resistance against Mycobacterium tuberculosis infection is independent of IFN-γ and TNF secretion from CD4(+) T cells.
9634 25594805 In the aspect of cytokines, the rSFTSV/NSs-vaccinated mice had a 5- to 10-fold increase in interleukin (IL)-2, IL-5, IL-6, IFN-γ, and tumor necrosis factor-α, which probably just had a negative effect on the bodyweight of mice.
9635 25597949 Short exposure to AFB1 suppressed innate immune transcripts, especially from antimicrobial genes, but increased the expression of transcripts from E3 ubiquitin-protein ligase CBL-B and multiple interleukin-2 response genes.
9636 25597949 Up-regulation of transcripts from lymphotactin, granzyme A, and perforin 1 could indicate either increased cytotoxic potential or activation-induced cell death in the spleen during aflatoxicosis.
9637 25622186 The functional maturation of BMDCs was confirmed by cytochemistry assay, FITC-dextran, acid phosphatase (ACP) activity, bio-assay and enzyme linked immunosorbent assay (ELISA).We elucidated that IL-2 up-regulated the expression of key surface markers such as: CD80, CD83, CD86, CD40 and MHC II molecules on BMDCs, down-regulated phagocytosis activity, induced more production of IL-12 and TNF-α secreted by BMDCs.
9638 25624476 In addition, it increased the number of CD8(+) tumor-infiltrating lymphocytes (TILs) and protected them from apoptosis and exhaustion characterized by decreased production of IL-2, TNFα, and IFNγ.
9639 25624476 CD8(+) TILs capable of producing multiple cytokines were mainly PD-1(-)Tim-3(+), an effector memory subset responsible for tumor rejection.
9640 25624476 Combined use of metformin and cancer vaccine improved CD8(+) TIL multifunctionality.
9641 25624476 The adoptive transfer of antigen-specific CD8(+) T cells treated with metformin concentrations as low as 10 μM showed efficient migration into tumors while maintaining multifunctionality in a manner sensitive to the AMP-activated protein kinase (AMPK) inhibitor compound C.
9642 25625932 This review compares the optimal use of vaccines vs. other forms of immunotherapy, which includes cytokines, such as IL-2, monoclonal antibodies, such as the 'checkpoint inhibitors', against CTLA-4 and PD-1.
9643 25626488 We have previously shown that interleukin-2-dependent NK and CD4(+) T-cell co-operative immune responses exist in long-term simian immunodeficiency virus (SIV) -infected controlling macaques and can be rescued in SIV-infected non-controlling macaques by a short course of antiretroviral therapy (ART).
9644 25626488 ART significantly decreased plasma and mucosal viral loads, increased the numbers of circulating CD4(+) T cells in all macaques, and increased T-cell-dependent envelope- and gag-specific interferon-γ and tumour necrosis factor-α production by circulatory CD56(+) NK cells.
9645 25632844 The US Food and Drug Administration (FDA) previously approved the therapeutic vaccine, sipuleucel-T, which is composed of autologous antigen-presenting cells cultured with a fusion protein [prostatic acid phosphatase (PAP) and granulocyte-macrophage colony-stimulating factor (GMCSF)].
9646 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.
9647 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.
9648 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.

9651 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.
9652 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.
9653 25643774 In the following literature review we present some of the better-known systemic treatment options for melanoma, from conventional chemotherapy, molecular (MAPK inhibitors) and immunomodulatory (interleukin-2, tumor necrosis factor alpha, cytotoxic T lymphocyte antigen-4 and programmed death-1 inhibitors) therapies, to miscellaneous options, among which are angiogenesis inhibitors, apoptosis modulators, vaccines, and radiotherapy.
9654 25701315 Cytokine and chemokine secretion in the serum of DNV-immunized mice showed elevated levels of IFN-γ, IL-2, IL-5, IL-12p40, IL-12p70, IL-17, eotaxin and RANTES, all of which have varying immune functions.
9655 25701315 Furthermore, we observed a DNV dose-dependent increase in the frequencies of IFN-γ-producing CD4(+) and CD8(+) T cells after in vitro stimulation of nucleated cells.
9656 25704800 A significant increase was observed in the cytokine levels of IL-2, IL-4 and IFN-γ in the culture supernatants of splenocytes.
9657 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.
9658 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.
9659 25754202 PEM did not change the overall numbers of CD4 T cells in BCG-vaccinated animals but resulted in an almost complete loss of antigen-specific cytokine production.
9660 25754202 Furthermore, there was a change in cytokine expression characterized by a gradual loss of multifunctional antigen-specific CD4 T cells and an increased proportion of effector cells expressing gamma interferon and tumor necrosis factor alpha (IFN-γ(+) TNF-α(+) and IFN-γ(+) cells).
9661 25754202 PEM during M. tuberculosis infection completely blocked the protection afforded by the H56-CAF01 subunit vaccine, and this was associated with a very substantial loss of the interleukin-2-positive memory CD4 T cells promoted by this vaccine.
9662 25754202 Similarly, PEM during the vaccination phase markedly reduced the H56-CAF01 vaccine response, influencing all cytokine-producing CD4 T cell subsets, with the exception of CD4 T cells positive for TNF-α only.
9663 25762364 As a surgery adjuvant approach, it comprised the co-injection of lipoplexes bearing herpes simplex virus thymidine kinase and canine interferon-β genes at the time of surgery, combined with the periodic administration of a subcutaneous genetic vaccine composed of tumor extracts and lipoplexes carrying the genes of human interleukin-2 and human granulocyte-macrophage colony-stimulating factor.
9664 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.
9665 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.
9666 25796990 And the recombinant virus induced the production of HIV-1 p24 specific immunoglobulin G (IgG), IL-2 and IL-4.
9667 25804480 Recently, adjuvant immunotherapy with anti-GD2 antibodies combined with IL-2 or GM-CSF has been shown to improve survival.
9668 25822536 Protection against Mycobacterium tuberculosis infection offered by a new multistage subunit vaccine correlates with increased number of IFN-γ+ IL-2+ CD4+ and IFN-γ+ CD8+ T cells.
9669 25822536 Antigen-specific single IL-2-secreting cells and different combinations with IL-2-secreting CD4+ T cells were beneficial and correlated with BCG vaccine-induced protection against TB.
9670 25822536 Antigen-specific IFN-γ+ IL-2+ CD4+ T cells were the only effective biomarker significantly induced by A1D4/MTO.
9671 25822536 Among all groups, A1D4/MTO immunization also conferred the highest number of antigen-specific single IFN-γ+ and IFN-γ+ TNF-α+ CD4+ T cells, which might be related to the antigen load in vivo, and single IFN-γ+ CD8+ T cells by mimicking the immune patterns of LTBIs or curable TB patients.
9672 25822536 Protection against Mycobacterium tuberculosis infection offered by a new multistage subunit vaccine correlates with increased number of IFN-γ+ IL-2+ CD4+ and IFN-γ+ CD8+ T cells.

9674 25822536 Antigen-specific IFN-γ+ IL-2+ CD4+ T cells were the only effective biomarker significantly induced by A1D4/MTO.
9675 25822536 Among all groups, A1D4/MTO immunization also conferred the highest number of antigen-specific single IFN-γ+ and IFN-γ+ TNF-α+ CD4+ T cells, which might be related to the antigen load in vivo, and single IFN-γ+ CD8+ T cells by mimicking the immune patterns of LTBIs or curable TB patients.

9678 25822536 Antigen-specific IFN-γ+ IL-2+ CD4+ T cells were the only effective biomarker significantly induced by A1D4/MTO.
9679 25822536 Among all groups, A1D4/MTO immunization also conferred the highest number of antigen-specific single IFN-γ+ and IFN-γ+ TNF-α+ CD4+ T cells, which might be related to the antigen load in vivo, and single IFN-γ+ CD8+ T cells by mimicking the immune patterns of LTBIs or curable TB patients.
9680 25849837 Results showed that, after three doses of vaccine, central memory and effector memory CD4(+) and CD8(+) T lymphocytes, as well as HPV-specific interleukin (IL)2(+)/CD4(+), interferon-gamma (IFN-γ(+))/CD4(+), IFN-γ(+)/CD8(+) and tumour necrosis factor-alpha (TNF-α)(+)/CD8(+) T lymphocytes and Perforin and Granzyme B secreting CD8(+) T lymphocytes were significantly increased.
9681 25855356 NK cells contribute to postvaccination immune responses after activation by IL-2 from Ag-specific memory T cells or by cross-linking of the low-affinity IgG receptor, CD16, by Ag-Ab immune complexes.
9682 25855356 CD56(dim)CD57(+) NK cells are less responsive to IL-2 and produce less IFN-γ in response to T cell-mediated activation than do CD56(bright) or CD56(dim)CD57(-) NK cells.
9683 25855356 Human CMV (HCMV), a highly prevalent herpes virus causing lifelong, usually latent, infections, drives the expansion of the CD56(dim)CD57(+)NKG2C(+) NK cell population, skewing the NK cell repertoire in favor of cytotoxic responses at the expense of cytokine-driven responses.
9684 25855356 Higher expression of CD57/NKG2C and lower expression of IL-18Rα on NK cells from HCMV seropositive subjects do not fully explain these impaired responses, which are likely the result of multiple receptor-ligand interactions.

9689 25892508 Comparison for sera biomarkers between narcolepsy (n = 84, 54 males, median age: 15.5 years old) and healthy controls (n = 41, 13 males, median age: 20 years old) revealed an increased stimulation of the immune system with high release of several pro- and anti-inflammatory serum cytokines and growth factors with interferon-γ, CCL11, epidermal growth factor, and interleukin-2 receptor being independently associated with narcolepsy.
9690 25892508 Comparison for sera biomarkers between patients with narcolepsy who developed the disease post-pandemic flu vaccination (n = 36) to those without vaccination (n = 48) revealed an increased stimulation of the immune system with high release of three cytokines, regulated upon activation normal T-cell expressed and secreted, CXCL10, and CXCL9, being independently and significantly increased in the group exposed to the vaccine.
9691 25907170 RpfE induces DC maturation by increasing expression of surface molecules and the production of IL-6, IL-1β, IL-23p19, IL-12p70, and TNF-α but not IL-10.
9692 25907170 This induction is mediated through TLR4 binding and subsequent activation of ERK, p38 MAPKs, and NF-κB signaling.
9693 25907170 RpfE-treated DCs effectively caused naïve CD4(+) T cells to secrete IFN-γ, IL-2, and IL-17A, which resulted in reciprocal expansions of the Th1 and Th17 cell response along with activation of T-bet and RORγt but not GATA-3.
9694 25919308 This modified method enhanced staining of IL-2 and IL-4, but not IFNγ, tumor necrosis factor alpha (TNFα), or IL-5.
9695 25924764 We identified high responders, intermediate responders, and nonresponders based on detection of interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-α), and gamma interferon (IFN-γ) expressing central (TCM) and effector memory CD4(+) T cells (TEM) 182 days after the first immunization.
9696 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.
9697 25934108 Additionally, CVPS enhanced CD40(+), CD80(+), and CD86(+) expression on DCs.
9698 25934108 In contrast, CVPS downregulated TGF-β mRNA expression and the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells.
9699 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.
9700 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.
9701 25941601 XBP1-CTL were enriched withCD45RO+ memory CTL, which showed high expression of critical T cell markers (CD28, ICOS, CD69, CD40L), cell proliferation and antitumor activities as compared to CD45RO- non-memory CTL.
9702 25941601 The effector memory (EM: CD45RO+CCR7-) subset had the highest level of cell proliferation while the central memory (CM: CD45RO+CCR7+) subset demonstrated enhanced functional activities (CD107a degranulation, IFNγ/IL-2 production) upon recognition of the respective tumor cells.
9703 25941601 The highest frequencies of IFNγ or granzyme B producing cells were detected within CM XBP1-CTL subset that were either Tbet+ or Eomes+ in responding to the tumor cells.These results demonstrate the immunotherapeutic potential of a cocktail of immunogenic HLA-A2 specific heteroclitic XBP1 US184-192 and heteroclictic XBP1 SP367-375 peptides to induce CD3+CD8+ CTL enriched for CM and EM cells with specific antitumor activities against a variety of solid tumors.
9704 25942359 A novel recombinant BCG-expressing pro-apoptotic protein BAX enhances Th1 protective immune responses in mice.
9705 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.
9706 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.
9707 25943203 Using peptide arrays and intracellular cytokine staining, we demonstrated that TDV elicits CD8(+) T cells targeting the nonstructural NS1, NS3, and NS5 proteins of TDV-2.
9708 25943203 The cells were characterized by the production of interferon-γ, tumor necrosis factor-α, and to a lesser extent interleukin-2.
9709 25947145 BCG vaccination induced an unexpectedly dichotomous immune response in this small, BCG-naive, young-adult cohort: BCG vaccination induced either gamma interferon-positive (IFN-γ(+)) interleukin 2-positive (IL-2(+)) tumor necrosis factor α-positive (TNF-α(+)) polyfunctional CD4(+) T cells concurrent with CD4(+) IL-17A(+) and CD8(+) IFN-γ(+) T cells or, in contrast, virtually absent cytokine responses with induction of CD8(+) regulatory T cells.
9710 25947145 Significant induction of polyfunctional CD4(+) IFN-γ(+) IL-2(+) TNF-α(+) T cells and IFN-γ production by peripheral blood mononuclear cells (PBMCs) was confined to individuals with strong immunization-induced local skin inflammation and increased serum C-reactive protein (CRP).
9711 25947145 Thus, BCG vaccination either induced a broad proinflammatory T cell response with local inflammatory reactogenicity or, in contrast, a predominant CD8(+) regulatory T cell response with mild local inflammation, poor cytokine induction, and absent polyfunctional CD4(+) T cells.
9712 25947145 BCG vaccination induced an unexpectedly dichotomous immune response in this small, BCG-naive, young-adult cohort: BCG vaccination induced either gamma interferon-positive (IFN-γ(+)) interleukin 2-positive (IL-2(+)) tumor necrosis factor α-positive (TNF-α(+)) polyfunctional CD4(+) T cells concurrent with CD4(+) IL-17A(+) and CD8(+) IFN-γ(+) T cells or, in contrast, virtually absent cytokine responses with induction of CD8(+) regulatory T cells.
9713 25947145 Significant induction of polyfunctional CD4(+) IFN-γ(+) IL-2(+) TNF-α(+) T cells and IFN-γ production by peripheral blood mononuclear cells (PBMCs) was confined to individuals with strong immunization-induced local skin inflammation and increased serum C-reactive protein (CRP).
9714 25947145 Thus, BCG vaccination either induced a broad proinflammatory T cell response with local inflammatory reactogenicity or, in contrast, a predominant CD8(+) regulatory T cell response with mild local inflammation, poor cytokine induction, and absent polyfunctional CD4(+) T cells.
9715 25959372 In the mechanistic study, H1N1-TMC/NP was shown to stimulate macrophages to produce IL-1β and IL-6 and to stimulate spleen lymphocytes to produce IL-2 and IFN-γ.
9716 25962477 The results demonstrated that the prime-boost strategy induced a potent antigen-specific immune response, which was primarily characterized by an enhanced T cell response and increased production of cytokines, including interferon-γ, tumor necrosis factor-α and interleukin-2, in mice.
9717 25971313 We have studied Ki-67 expression and FLUAVsw-specific production of IFN-γ, TNF-α and IL-2 in CD4(+) and CD8β(+) T cells isolated from piglets that had been intratracheally infected with a H1N2 FLUAVsw isolate.
9718 25971313 IFN-γ(+)TNF-α(+)IL-2(+) multifunctional CD4(+) T cells were present in the blood of all infected animals at one or two weeks after primary infection and their frequency increased in four out of six animals after homologous secondary infection.
9719 25971313 These cells produced higher amounts of IFN-γ, TNF-α and IL-2 than did CD4(+) T cells that only produced a single cytokine.
9720 25971313 Analysis of CD27 expression suggested that FLUAVsw-specific CD4(+) T cells included both central memory and effector memory populations.
9721 25971313 We have studied Ki-67 expression and FLUAVsw-specific production of IFN-γ, TNF-α and IL-2 in CD4(+) and CD8β(+) T cells isolated from piglets that had been intratracheally infected with a H1N2 FLUAVsw isolate.
9722 25971313 IFN-γ(+)TNF-α(+)IL-2(+) multifunctional CD4(+) T cells were present in the blood of all infected animals at one or two weeks after primary infection and their frequency increased in four out of six animals after homologous secondary infection.
9723 25971313 These cells produced higher amounts of IFN-γ, TNF-α and IL-2 than did CD4(+) T cells that only produced a single cytokine.
9724 25971313 Analysis of CD27 expression suggested that FLUAVsw-specific CD4(+) T cells included both central memory and effector memory populations.
9725 25971313 We have studied Ki-67 expression and FLUAVsw-specific production of IFN-γ, TNF-α and IL-2 in CD4(+) and CD8β(+) T cells isolated from piglets that had been intratracheally infected with a H1N2 FLUAVsw isolate.
9726 25971313 IFN-γ(+)TNF-α(+)IL-2(+) multifunctional CD4(+) T cells were present in the blood of all infected animals at one or two weeks after primary infection and their frequency increased in four out of six animals after homologous secondary infection.
9727 25971313 These cells produced higher amounts of IFN-γ, TNF-α and IL-2 than did CD4(+) T cells that only produced a single cytokine.
9728 25971313 Analysis of CD27 expression suggested that FLUAVsw-specific CD4(+) T cells included both central memory and effector memory populations.
9729 25974877 Mechanistically, the immune protection was attributed to stronger antigen-specific CD4(+) Th1 responses, higher numbers of IFN-γ(+) CD4(+) TEM and IL-2(+) CD8(+) TCM cells elicited by ABX.
9730 25989924 The TPPPS-PP group showed the highest levels of antibody titres and interleukin-2 (IL-2) at 14-28 days post the first inoculation (dpi), lymphocyte transformation rates (LTRs) at 14-35 dpi, CD4(+) T-lymphocyte counts at 14-42 dpi, and CD8(+) T-lymphocyte counts at 28 dpi.
9731 25992289 NK cells and CD8+ T cells cooperate to improve therapeutic responses in melanoma treated with interleukin-2 (IL-2) and CTLA-4 blockade.
9732 26009966 The cellular responses were assessed by interferon-γ (IFN-γ) ELISPOT and by intracellular staining (ICS) for the Th1 cytokines IFN-γ, interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α).
9733 26019274 To achieve this, vaccine Ags need to be targeted to the cytosol of dendritic cells, which can activate CD8 T cells via MHC class I (MHCI).
9734 26019274 Immunization in the presence of TPCS2a significantly increased activation of CD8 T cells compared with immunization without TPCS2a and as measured by CD8 T cell proliferation, production of proinflammatory IFN-γ, TNF-α, and IL-2, and prevention of tumor growth.
9735 26019274 CD4-dependent Ab responses were abrogated in mice immunized with TPCS2a-containing particles, suggesting that photosensitization facilitated a shift from default MHC class II toward MHCI Ag presentation.
9736 26031574 Based on the results of preclinical studies, we designed a phase Ib trial (TSPP/VAC1) to investigate, in a dose escalation setting, the safety and the biological activity of TSPP vaccination alone (arm A) or in combination with GM-CSF and IL-2 (arm B) in cancer patients.
9737 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.
9738 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).

9741 26049546 Following short-term (14 d) culture activation with anti-CD3/anti-CD28 microbeads and expansion in low concentrations of IL-2, the melanoma-draining lymph node (MDLN) cells were ∼ 60% CD4-activated and ∼ 40% CD8-activated T cells.
9742 26049546 The activated MDLN cells demonstrated reactivity in response to overlapping peptides spanning the sequence of 4 different known melanoma antigens MAGEA1, Melan-A/MART-1, NY-ESO-1, and Prame/OIP4, suggesting the presence of melanoma-specific T cells.
9743 26049546 Although prior human studies have demonstrated the immune responses within melanoma vaccine-draining lymph nodes, this study presents evidence for the first time that naturally occurring human MDLN samples contain melanoma-experienced CD4 and CD8 T cells that can be readily cultured and expanded to mediate protective immune responses both in vitro and in vivo in a human melanoma xenograft model.
9744 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.

9781 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.
9782 26082759 Interleukin 2 (IL-2), for example, significantly stimulates the activation of CD8+ T cells and other immune cells.
9783 26091502 Low expression of activation marker CD69 and chemokine receptors CCR5 and CXCR3 on memory T cells after 2009 H1N1 influenza A antigen stimulation in vitro following H1N1 vaccination of HIV-infected individuals.
9784 26091502 Cells collected just prior to vaccination and at 1 and 3 months afterwards were stimulated in vitro with dialyzed vaccine antigen and assayed by flow cytometry for cytokines TNF-α, IFN-γ, IL-2, and IL-10, for degranulation marker CD107a, as well as phenotypes of memory T-cell subpopulations.
9785 26091502 However, by 3 months post-vaccination, in vitro antigen stimulation of peripheral blood mononuclear cells induced greater expansion in controls of both CD4 and CD8 central memory and effector memory T cells, as well as higher expression of the activation marker CD69 and chemokine receptors CCR5 and CXCR3 than in HIV+ subjects.
9786 26091502 We concluded CD4+ and CD8+ memory T cells produce cytokines at comparable levels in both groups, whereas the expression after in vitro stimulation of molecules critical for cell migration to infection sites are lower in the HIV+ than in comparable controls.
9787 26111521 Enhanced protection was accompanied by increased multifunctional Th1 CD4(+) T cell responses, most notably by an elevated frequency of M. tuberculosis antigen-specific IL-2-producing CD4(+) T cells post-vaccination.
9788 26123802 Role of CD4+ Foxp3+ Regulatory T Cells in Protection Induced by a Live Attenuated, Replicating Type I Vaccine Strain of Toxoplasma gondii.
9789 26123802 Intraperitoneal injection of Mic1.3KO induced a weak and transient influx of CD4(+) Foxp3(+) T regulatory cells followed by recruitment/expansion of CD4(+) Foxp3(-) CD25(+) effector cells and control of the parasite at the site of infection.
9790 26123802 In contrast, injection of RH, the wild-type strain from which the vaccinal strain is derived, induced a low CD4(+) Foxp3(+) cell influx and uncontrolled multiplication of the parasites at this local site, followed by death of the mice.
9791 26123802 In addition, in vivo Treg induction in RH-infected mice with interleukin-2 (IL-2)/anti-IL-2 complexes induced control of the parasite and a TH1/Treg cytokine response similar to the response after Mic1.3KO vaccination.
9792 26130856 A potent lymphocyte-proliferation response and increased levels of interferon-γ, interleukin-2, and interleukin-6 in the plasma and in culture supernatants of antigen-stimulated lymphocytes from the vaccinated group suggested significant induction of the cell-mediated immune response in this group compared with the control group.
9793 26133045 A single immunization of mice with replication incompetent recombinant adenovirus vectors encoding for F or core antigens induces poor T cell responses and leads to generation of CD4+ and CD8+ T cells with low granzyme B (GrB) expression.
9794 26133045 Addition of exogenous IL-2 in in vitro cultures leads to partial recovery of GrB production, whereas immunization with the Toll-like receptor (TLR) agonist poly I:C leads to complete restoration of GrB expression in both CD4+ and CD8+ T cells.
9795 26137874 HBsAg-specific T cells were analyzed by flow cytometry according to expression of activation markers CD40L and/or CD69, and the cytokines IFNγ, IL-2, TNFα, and IL-17.
9796 26148331 We observed that at d 3-4 post vaccination, 6 genes were down-regulated, namely APC, CD3G, FASLG, IL7, CD8A and TLR1.
9797 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.
9798 26148331 By days 12-15 the genes RIPK2, IL4, IL12B and TLR2 were overexpressed.
9799 26169275 In vitro infection of macrophages with live attenuated parasites (compared to that with wild-type [WT] L. donovani parasites) induced significantly higher production of proinflammatory cytokines (tumor necrosis factor alpha [TNF-α], interleukin-12 [IL-12], gamma interferon [IFN-γ], and IL-6), chemokines (monocyte chemoattractant protein 1/CCL-2, macrophage inflammatory protein 1α/CCL-3, and IP-10), reactive oxygen species (ROS), and nitric oxide, while concomitantly reducing anti-inflammatory cytokine IL-10 and arginase-1 activities, suggesting a dominant classically activated/M1 macrophage response.
9800 26169275 Similarly, parasitized splenic macrophages from live attenuated parasite-infected mice also demonstrated induction of an M1 macrophage phenotype, indicated by upregulation of IL-1β, TNF-α, IL-12, and inducible nitric oxide synthase 2 and downregulation of genes associated with the M2 phenotype, i.e., the IL-10, YM1, Arg-1, and MRC-1 genes, compared to WT L. donovani-infected mice.
9801 26169275 Furthermore, an ex vivo antigen presentation assay showed macrophages from live attenuated parasite-infected mice induced higher IFN-γ and IL-2 but significantly less IL-10 production by ovalbumin-specific CD4(+) T cells, resulting in proliferation of Th1 cells.
9802 26175894 A robust immune response to each component of the vaccine with polyfunctional CD4 TH1 cell responses characterized by production of antigen-specific interferon-γ, tumor necrosis factor and interleukin-2 (IL-2), and low levels of IL-5 and IL-10 was induced in immunized mice.
9803 26175894 We also demonstrate that CD4 T cells, but not CD8 T cells, are sufficient for protection against L. donovani infection in immunized mice.
9804 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.
9805 26195801 IL-15 receptor α signaling constrains the development of IL-17-producing γδ T cells.
9806 26195801 Here we examine the role of IL-15 and its unique receptor, IL-15Rα, in the development of IL-17-producing γδ (γδ-17) T cells.
9807 26195801 Phenotypic analysis has shown that CD44(high) γδ-17 cells express IL-15Rα and the common gamma chain (CD132), yet lack the IL-2/15Rβ chain (CD122).
9808 26195801 Finally, an analysis of neonatal thymi revealed that the CD44(lo/int) precursors of γδ-17 cells, which also expressed IL-15Rα, were increased in newborn mice deficient in IL-15Rα signaling, but not in IL-15 itself.
9809 26204190 Chimeric DNA vaccines co-expressing Eimeria acervulina macrophage migration inhibitory factor (E.MIF) and chicken IL-2 (IL-2) or interferon-γ (IFN-γ) were constructed and their efficacies against E. acervulina were evaluated.
9810 26230145 Variants that enhanced interferon-gamma (IFN-γ) and/or interleukin-2 (IL-2) production in enzyme-linked immunospot assays (29 cases overall) were subsequently tested by 7-day in vitro peptide stimulation for their effects on HIV-specific CD8(+) T cell proliferation and programmed death-1 (PD-1) expression.
9811 26230145 Heteroclitic variants enhanced HIV-specific CD8(+) T cell proliferation by >20% in 13/29 cases tested, reduced PD-1 expression on proliferating cells by 15-50% in 10 cases, and reduced PD-1 expression on proliferating cells by >50% in 3 cases.
9812 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.
9813 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.
9814 26283355 IL-2 and IL-15, members of the gamma chain (γc) family of cytokines, are prominently deregulated in HAM/TSP and underlie many of the characteristic immune abnormalities, such as spontaneous lymphocyte proliferation (SP), increased STAT5 phosphorylation in the lymphocytes, and increased frequency and cytotoxicity of virus-specific cytotoxic CD8(+) T lymphocytes (CTLs).
9815 26283355 In this study, we describe a novel immunomodulatory strategy consisting of selective blockade of certain γc family cytokines, including IL-2 and IL-15, with a γc antagonistic peptide.
9816 26283355 This strategy is thus a promising therapeutic approach to HAM/TSP with the potential of being more effective than single monoclonal antibodies targeting either IL-2 or IL-15 receptors and safer than inhibitors of downstream signaling molecules such as JAK1 inhibitors.

9830 26334199 Our results indicated that the indices of both thymus and bursa of fabricius, the intactness of tissue structure and development, the plasma levels of IL-2, IgA, IgG and IgM, the titres of ND antibody, and the levels of B and T lymphocyte subsets in HS group were all significantly lower than those in CK group (p < 0.05).
9831 26343487 Mice vaccinated with pSCA1/F had increased IL-2 and IL-10 levels after 24-h post first immunization.
9832 26361864 Furthermore, using flow cytometry based intracellular cytokine staining (ICCS) assay HIV-1C specific IL-2 responses were detected in immunized mice that were mediated by both CD4(+) and CD8(+) T cells.
9833 26363555 The rBCG::XB not only elicited the more durable multistage antigen-specific CD4(+)Th1-biased immune responses and specific polyfunctional CD4(+)T cells but also augmented the CD8(+) CTL effects against Ag85B in vivo.
9834 26363555 In particular, higher levels of CD4(+) TEM and CD8(+) TCM cells, dominated by IL2(+) CD4(+) and CD8(+) TCM cells, were obtained in the spleen of rBCG::XB vaccinated mice.
9835 26373843 It was shown that direct injection of LV-Ub-HBcAg increased the production of cytokines IL-2 and IFN-γ, elicited strong antibody responses, and remarkably generated a high percentage of IFN-γ+CD8+ T cells with HBV-specific CTL responses in BALB/c mice.
9836 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.
9837 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.
9838 26399380 When antigens are presented by APCs, including macrophages and DCs, T cells are activated and produce the Th1 cytokines IL-2 and IFN-γ.
9839 26410627 IL-2-mediated activation of the Akt kinase and mTORc1 signaling was both necessary and sufficient to shift differentiation away from Tfh cells, instead promoting that of Th1 cells.
9840 26424604 Multicolor flow cytometry was used to evaluate expression of CD4, CD25, and intracellular Foxp3 on PBMCs.
9841 26424604 Cell culture supernatants from BSA re-stimulated lymphocytes were evaluated for concentrations of IL-2, IL-4, IL-10, and IFN-γ.

9843 26439698 We observed that PPE26-treated macrophages effectively polarizes naïve CD4(+) T cells to up-regulate CXCR3 expression, and to secrete IFN-γ and IL-2, indicating PPE26 contributes to the Th1 polarization during the immune response.
9844 26439698 Moreover, PPE26 effectively induces the reciprocal expansion of effector/memory CD4(+)/CD8(+) CD44(high)CD62L(low) T cells in the spleens of mice immunized with this strain.
9845 26450390 ELISpot is also able to quantify other cytokines secreted by antigen-specific T-cells, such as interleukin-2, interleukin-5, and other interleukins.
9846 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.

9850 26453748 The amount of IL-2 produced on a per-cell basis essentially connects directly to the superior CD8(+) T cell population expansion.
9851 26453748 Together, our findings identified that autocrine IL-2 production operates in a dose-dependent fashion to facilitate the expansion potential of Ag-specific CD8(+) T cell populations, which may instigate ways to augment therapies depending on fit CD8(+) T cells.

9866 26453748 Together, our findings identified that autocrine IL-2 production operates in a dose-dependent fashion to facilitate the expansion potential of Ag-specific CD8(+) T cell populations, which may instigate ways to augment therapies depending on fit CD8(+) T cells.
9867 26453748 The Quantity of Autocrine IL-2 Governs the Expansion Potential of CD8+ T Cells.
9868 26453748 In this study, we show in mouse models that the relative number of IL-2-producing cells within Ag-specific CD8(+) T cell populations predicts the population expansion capacity upon challenge.
9869 26453748 Notably, we show that elevated production of IL-2 by CD8(+) T cells results in concomitant improved population expansion capacity and immunity.
9870 26453748 The amount of IL-2 produced on a per-cell basis essentially connects directly to the superior CD8(+) T cell population expansion.
9871 26453748 Together, our findings identified that autocrine IL-2 production operates in a dose-dependent fashion to facilitate the expansion potential of Ag-specific CD8(+) T cell populations, which may instigate ways to augment therapies depending on fit CD8(+) T cells.
9872 26465323 Specifically, Th1-specific cytokines (IFN-γ, IL-2, TNF-α), CD40 ligand and the Th1 lineage-specifying transcription factor Tbet were determined upon stimulation with peptides covering the TBEV structural proteins contained in the vaccine (C-capsid, prM/M-membrane and E-envelope).
9873 26465882 The specific secretion of IL-10 in primary response and IL-2,IP-10,CCL14a, CCL21 in recall response was consistent with the activation of immune response process found in genes.
9874 26465882 Furthermore, the expression of MX1 and secretion of IP-10 in recall response were strongly correlated with NTAb level at 180d after vaccination (r = 0.81 and 0.99).
9875 26466957 We developed a flow cytometric assay to profile CD1-restricted T cells ex vivo and assessed T cell responses to five cell wall lipid Ags in a cross-sectional study of 19 M. tuberculosis-infected and 22 M. tuberculosis-uninfected South African adolescents.
9876 26466957 We show that CD1b-restricted T cells producing antimycobacterial cytokines IFN-γ and TNF-α are detectable ex vivo in CD4(+), CD8(+), and CD4(-)CD8(-) T cell subsets.
9877 26466957 Glucose monomycolate was immunodominant among lipid Ags tested, and polyfunctional CD4 T cells specific for this lipid simultaneously expressed CD40L, IFN-γ, IL-2, and TNF-α.
9878 25503054 Th17 cells were defined as IL-17+ CD4+ T cells and their function was assessed by the co-expression of IL-22, IL-2 and IFNγ.
