1 7495512 Pathogen induction of IL-12 elicits interferon-gamma production by natural killer cells, which contributes to early defense during certain bacterial, parasitic, and viral infections.
2 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.
3 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.
4 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.

9 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.
10 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.

29 7636200 Although not affecting the outcome of primary challenge, serologic ablation of TGF-beta in the former animals abrogated development of acquired resistance and resulted in impaired production of IL-12/IFN-gamma and higher expression of IL-4/IL-10 at the time of reinfection with virulent yeast.
30 7636200 In addition to previous evidence for an obligatory role of IFN-gamma and IL-12 in Candida-driven Th1 cell differentiation in vivo, the present data establish TGF-beta as a third cytokine, the presence of which may be required for optimal Th1 development leading to long-lived anticandidal resistance.

36 7705395 Interleukin-12 is required for interferon-gamma production and lethality in lipopolysaccharide-induced shock in mice.
37 7705395 Several cytokines, in particular tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma), have been shown to be responsible for pathological reactions which may lead to shock and death observed in infection with Gram-negative bacteria and in response to endotoxins (lipopolysaccharides, LPS).
38 7705395 In response to low doses (1 microgram/mouse) of LPS, BCG-primed mice produce interleukin-12 (IL-12) which controls IFN-gamma production, as demonstrated by the ability of neutralizing anti-IL-12 antibodies to suppress IFN-gamma production.
39 7705395 However, the concentration of the biologically active IL-12 p70 heterodimer is similar in the serum of both BCG-primed or unprimed mice, reaching levels of 1-3 ng/ml at 3-6 h after LPS injection, whereas IFN-gamma production was observed only in BCG-primed mice.
40 7705395 The priming effect of BCG on IFN-gamma production appears to be mostly due to its ability to increase TNF-alpha production, which acts as cofactor with LPS-induced IL-12 in inducing IFN-gamma production, as shown by the ability of injection of TNF-alpha and LPS (1 microgram/mouse), but not LPS alone, to induce IFN-gamma production.
41 7705395 However, in addition to TNF-alpha, other LPS-induced cofactor(s) are required in cooperation with IL-12 to induce optimal IFN-gamma production, because co-injection of TNF-alpha and IL-12, sufficient to induce serum concentrations of both cytokines higher and more persistent than those obtained by injection of LPS, was not sufficient to induce IFN-gamma production in vivo.

64 7705395 Interleukin-12 is required for interferon-gamma production and lethality in lipopolysaccharide-induced shock in mice.
65 7705395 Several cytokines, in particular tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma), have been shown to be responsible for pathological reactions which may lead to shock and death observed in infection with Gram-negative bacteria and in response to endotoxins (lipopolysaccharides, LPS).
66 7705395 In response to low doses (1 microgram/mouse) of LPS, BCG-primed mice produce interleukin-12 (IL-12) which controls IFN-gamma production, as demonstrated by the ability of neutralizing anti-IL-12 antibodies to suppress IFN-gamma production.
67 7705395 However, the concentration of the biologically active IL-12 p70 heterodimer is similar in the serum of both BCG-primed or unprimed mice, reaching levels of 1-3 ng/ml at 3-6 h after LPS injection, whereas IFN-gamma production was observed only in BCG-primed mice.
68 7705395 The priming effect of BCG on IFN-gamma production appears to be mostly due to its ability to increase TNF-alpha production, which acts as cofactor with LPS-induced IL-12 in inducing IFN-gamma production, as shown by the ability of injection of TNF-alpha and LPS (1 microgram/mouse), but not LPS alone, to induce IFN-gamma production.

86 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.
87 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).

115 7903204 Histological examination of tumor inoculum with 3T3-IL-12 secreting a high level of IL-12 showed peritumoral accumulation of macrophages, a characteristic capsule around the tumor composed of palisades of fibroblasts, and decreased numbers of CD4+ cells in the tumor.

122 7904381 Vaccination of BALB/c mice with leishmanial antigens and interleukin-12 (IL-12) promoted the development of leishmanial-specific CD4+ TH1 cells.
123 7911046 It has been shown to be necessary for the T cell independent induction of interferon (IFN)-gamma, critical for the initial suppression of bacterial and parasitic infection; for the development of a Th1 response, critical for effective host defense against intracellular pathogens; and for the activation of differentiated T lymphocytes of both CD4+ and CD8+ phenotype.
124 7911046 In addition to the therapeutic potential associated with IL-12 activity in these disease models, the understanding of its role in immune development and interaction with other cytokines, particularly antagonists, such as IL-4 and IL-10, has clarified and extended our understanding of immune regulation and should lead to significant developments in understanding the progression of AIDS and the development of vaccine adjuvants able to direct the immune response.
125 7929809 We here report the unexpected observations that IL-12 exerts differential effects on the maturation of "native" human CD4 T cells isolated from umbilical cord blood or from the blood of healthy adults.
126 7929809 After priming in the presence of IL-12, naive cells of adult donors, defined as CD45R0- CD4+ T cells, acquire a Th1 phenotype whereas neonatal cells develop into effector cells producing high levels of IL-4 in addition to IFN-gamma.
127 7929809 This effect of IL-12 on neonatal T cells is direct inasmuch as it is observed on highly purified CD4 T cells, however, it is not inhibited by CD8 T cells and natural killer cells.
128 7929809 Given that IL-4 is a potent antagonist of Th1 responses, the finding that IL-12 promotes the maturation of neonatal T cells into IL-4 producers may explain the increased susceptibility of neonates to intracellular pathogens and should be taken into account for the development of vaccines to be used in the perinatal period.

141 7963574 In the present study, IL-12-neutralizing Abs or recombinant IL-12 were administered to mice with healing or progressive candidiasis, respectively, and the animals were monitored for mortality, resistance to reinfection, serum levels of specific Abs, and IFN-gamma, IL-4, and IL-10 message/protein expression by CD4+ cells.
142 7963574 In mice with progressive systemic disease as well as in a mucosal infection model, administration of IL-12 did not result in therapeutic activity under conditions of yeast infection that would instead be resolved by serologic ablation of IL-4 or IL-10.
143 7963574 Yet, in systemically infected mice cured by anti-IL-4 or anti-IL-10 therapy, the emergence of a Th1 response correlated with the detection of high levels of circulating IL-12 and splenic IL-12 transcripts.
144 7963574 Although exogenous IL-12 may not be sufficient for Th conversion in the presence of an overwhelming IL-4/IL-10 response, endogenous production of IL-12 may be both required and prognostic for Th1 differentiation in vivo.

149 8551248 Furthermore, depletion of either CD4+ or CD8+ T cells from tumor-bearing mice before therapy totally suppressed the therapeutic efficacy of DC pulsed with tumor-derived peptides.
150 8551248 The analysis of the cytokine pattern in the draining lymph nodes and spleens of tumor-bearing mice immunized with DC pulsed with tumor-eluted peptides revealed a marked upregulation of interleukin (IL) 4 and interferon (IFN) gamma production, as compared with mice immunized with DC alone or DC pulsed with irrelevant peptides.
151 8551248 DC-induced antitumor effects were completely blocked by coadministration of neutralizing monoclonal antibody directed against T helper cell 1-associated cytokines (such as IL-12, tumor necrosis factor alpha, IFN-gamma), and eventually, but not initially, blocked by anti-mIL-4 mAb.
152 8557339 In vitro IL-12 neutralization dramatically impaired the IFN-gamma response to S. typhimurium but not to ConA.
153 8557339 Thus, in primary Salmonella infections, IL-12 mediates the suppression of growth of virulent salmonellae in the reticuloendothelial system, positively modulates IFN-gamma production, and is involved in the immunosuppression which accompanies the acute stages of the disease.

157 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.
158 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.
159 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.
160 8604226 Additional cytokines such as IL-10 and IL-12 are likely to contribute to the regulation of this response.

181 8609419 Furthermore, we detected an expression of IFN-gamma by both adherent and nonadherent spleen cells at the early stage of stimulation with VLM before the appearance of IFN-gamma-producing CD4+ T cells.
182 8609419 These data suggest that HKLM induce nonadherent spleen cells to produce IL-10 which may down-regulate IFN-gamma-producing CD4+ T cells by blocking IL-12 production by M phi.
183 8609419 In contrast, VLM support IFN-gamma production by CD4+ T cells by stimulating M phi to produce IL-12 and IFN-gamma.
184 8627759 FI-RSV-immunized mice had an increased number of total cells, granulocytes, eosinophils, and CD4+ cells but a decreased number of CD8+ cells.
185 8627759 The immunized mice also had a marked increase in the expression of mRNA for the Th2-type cytokines interleukin-5 (IL-5) and IL-13 as well as some increase in the expression of IL-10 (a Th2-type cytokine) mRNA and some decrease in the expression of IL-12 (a Th1-type cytokine) mRNA.
186 8647214 IL-12 also synergizes with B7.1 (CD80) co-stimulation to induce proliferation and cytokine production by both human and murine T cells in vitro.
187 8647214 The synergistic anti-tumor effects associated with combined application of B7.1- and IL-12-transfected tumors were partially negated by systemic administration of the CD28-B7.1/B7.2 antagonist CTLA4-Ig or by inoculation with neutralizing antibodies directed against murine interferon-gamma or tumor necrosis factor-alpha, two cytokines elicited in response to IL-12 stimulation.

210 8706049 Bacillus Calmette-Guérin plus interleukin-2 and/or granulocyte/macrophage-colony-stimulating factor enhances immunocompetent cell production of interferon-gamma, which inhibits B16F10 melanoma cell growth in vitro.
211 8706049 Tumor necrosis factor alpha was substantially weaker (IC50 > 10 ng/ml) but provided synergy with IFN gamma.
212 8706049 None of the other cytokines such as interleukin-2 (IL-2), IL-4, IL-6, IL-10, IL-12, or granulocyte/macrophage-colony-stimulating factor had direct antitumor activity against B16F10 melanoma cells.
213 8706049 However, when IL-2 and/or GM-CSF were combined with BCG either by exogenous addition or through endogenous production by novel cytokine-secreting recombinant BCG (rBCG), a substantial increase in INF gamma production by splenocytes was observed.
214 8706049 These results suggest that BCG may exert part of its antitumor action on melanoma through the induction of IFN gamma, which can be greatly enhanced through the concomitant addition of IL-2 and/or GM-CSF.

222 8757841 Development of a vaccine which is capable of generating a strong cellular immune response associated with gamma interferon (IFN-gamma) production and cytotoxic T-cell development requires that the immunogen be capable of inducing the secretion of interleukin-12 (IL-12), which is a pivotal factor for the differentiation of Th1 or Tc1 cells.

250 8861033 Protective immunity is associated with a CD4 and CD8 T-cell response towards a mosaic of proteins of F. tularensis and due to HLA restriction, each individual selects her own mosaic.
251 8861033 In mice, intradermal injection of live F. tularensis but not of killed bacteria results in an early cytokine expression in the infected liver, including interleukin-12, tumor necrosis factor-alpha, and interferon-gamma.

254 8877133 Differential effects of interleukin-12, interleukin-15, and interleukin-2 on human immunodeficiency virus type 1 replication in vitro.
255 8877133 The effect of interleukin-12 (IL-12) and IL-15 on in vitro HIV-1 replication was investigated.
256 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.
257 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).
258 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).
259 8877133 We next studied the effect of IL-12 and IL-15 on HIV-infected peripheral blood mononuclear cells (PBMCs).
260 8877133 In 10 HIV-seropositive patients' PBMCs cocultured with mitogen-activated HIV-seronegative donor cells, two patterns of p24 antigen production were observed in response to IL-2: low (p24 antigen production < 10(3) pg/ml; n = 8) and high (p24 antigen production > 10(3) pg/ml; n = 2) response.
261 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).

442 8977282 Interleukin-10 and interleukin-4 have similar effects on hapten-specific primary antibody responses to penicillin in vivo.
443 8977282 Interleukin (IL)-10 was initially recognized on the basis of its capacity to inhibit production of interferon (IFN)-gamma by T helper (Th)1 lymphocytes; we examined whether this cytokine can bias the primary antibody (Ab) response to the hapten penicillin.
444 8977282 Neutralization on administration of IL-10 had effects very similar to neutralization or administration of IL-4.
445 8977282 However, co-neutralization of IL-10 and IL-4 in SJL did not evidence additive or synergistic effects of the two cytokines.
446 8977282 Administration of IL-10 or IL-4 in BALB/c inhibited BPO-TT-induced expression of IL-12 p40 mRNA without modulating IFN-gamma mRNA.
447 8977282 Together, these data demonstrate that endogenous production of IL-10 regulates the production of IgG2a Ab in response to BPO-TT and that IL-10, like IL-4, is critical for controlling primary responses to antibiotics which behave as haptenic compounds.

472 9022016 Moreover, it is likely that IL-4 dominates over IL-12, suggesting that Th2 cell development is preferred in the presence of both cytokines.
473 9022016 Here we show that BCG and IL-12 down-modulate IL-4-producing CD4+ NK1+ TCR alpha/beta(intermediate) liver lymphocytes.

479 9036985 We found that neutrophils were endowed with the capacity to secrete IL-12 and IL-10 in vitro in response to the yeast.
480 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.
481 9053442 When IL-12 complexed to liposomes was given orally both shifts to IgG2a and IgG3 and low IgE Abs again occurred concomitant with enhanced serum IFN-gamma and DTH responses.
482 9063493 In these models Th1 cells producing IFN-gamma provide protection against the infection whereas Th2 cells producing IL-4 and IL-10 aggravate the disease.
483 9063493 IFN-gamma, IL-12) will favour maturation of Th1 responses whereas others (e.g.
484 9063493 IL-4, IL-10) support Th2 development.
485 9103425 These motifs rapidly trigger an innate immune response, characterized by the production of IL-6, IL-12, and IFN-gamma.
486 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.
487 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.
488 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.
489 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.
490 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).

552 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.

554 9278339 We found that these particles induced IL-12, TNF-alpha, and IFN-gamma.
555 9278339 The treatments with soluble mannan or with cytochalasin D, in sharp contrast, did not inhibit LPS-induced IL-12/IFN-gamma production or exogenous IL-12-induced IFN-gamma production.
556 9278339 Finally, spleen cells from C3H/HeJ mice also showed comparable levels of IL-12/TNF-alpha/IFN-gamma production when induced by 1 to 10 microm chitin particles.
557 9278339 Taken together, our results indicate that mannose receptor-mediated phagocytosis, but not the receptor-mediated pinocytosis, is highly associated with the production of IFN-gamma-inducing extracellular signaling factors such as IL-12 and TNF-alpha.

578 9285547 To investigate if this might be caused by a preferential Th1 cytokine response, interferon (IFN)-gamma and interleukin (IL)-10 production of peripheral blood mononuclear cells (PBMC) was analyzed after measles antigen (M-ag) stimulation in vitro.
579 9285547 The non-specific immune response was measured by IFN-alpha, and IL-12 analyses.
580 9285547 Only a non-significant tendency was seen in IL-10 production (48.6 vs 26.7 pg/ml; NS), whereas no difference was found in IFN-alpha or IL-12 production.
581 9285547 A positive correlation between IFN-gamma and IL-10 production was found (r(s) = 0.49; P < 0.001).
582 9285547 After vaccination of 14 ABMT children, there was an increase in PBMC IFN-gamma production in vitro (2.5 vs <0.1 IU/ml; P < 0.05), whereas no changes were seen in the IL-10, IFN-alpha, or antibody levels.

588 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.
589 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.
590 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.

592 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.

597 9314562 Moreover, both the enhancement of IFN-gamma production and the protective immune response induced by LACK DNA vaccination was IL-12 dependent.
598 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.

600 9317031 The objective of these experiments was to examine the ability of Helicobacter pylori to stimulate interleukin-10 (IL-10) or IL-12 and select for either Th1 or Th2 cells.
601 9317031 As Th1 and Th2 cells are selected by IL-12 and IL-10, respectively, biopsy specimens were screened for mRNA and protein for these cytokines.
602 9317031 Although mRNA for IL-12 and IL-10 was detected in biopsy specimens obtained from both infected and uninfected patients, IL-12 protein predominated.
603 9317031 Levels of IL-10 and IL-12 in gastric tissue did not change in response to infection.
604 9317031 Stimulation of peripheral blood leukocytes from either infected or uninfected donors with various concentrations of live or killed H. pylori induced immunoreactive IL-12 and IL-10.
605 9317031 After stimulation with live H. pylori, IL-12 levels increased more than 30-fold, whereas IL-10 levels increased only 2- to 5-fold, compared to cells stimulated with medium alone.
606 9317031 These results demonstrate that live H. pylori selectively stimulates the induction of IL-12 and Th1 cells that produce IFN-gamma, whereas preparations used in oral vaccines induce more IL-10 and may favor Th2 cell responses.

663 9341778 We and others have demonstrated that single-stranded (ss) DNA containing the motif CpG flanked by two 5' purines and two 3' pyrimidines are mitogenic for B cells and activate macrophages to release tumor necrosis factor-alpha, interferon-gamma, interleukin (IL)-6 or IL-12.
664 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.
665 9341783 Infiltrating leukocytes were also characterized for expression of co-stimulatory molecules like CD54, CD86 and major histocompatibility complex class II.
666 9341783 The intratumoral DC content was dependent on the type of transduced cytokines with C26/IL-4 being the most abundant in DEC205+ cells.
667 9341783 In comparison with C26/GM-CSF, C26/IL-4 had more B7.2+ cells but less Ia+ cells.
668 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.
669 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.
670 9353029 These CD8+ T cells secrete IFN-gamma and enhance the production of interleukin 12 when cocultured with M. tuberculosis-infected macrophages.
671 9362523 Synthetic oligodeoxynucleotides (ODN) that contain unmethylated CpG motifs (CpG ODN) induce macrophages to secrete IL-12, which induces interferon (IFN)-gamma secretion by natural killer (NK) cells.
672 9362523 In both BALB/c (Th2-biased) and B10.D2 (Th1-biased) mice, immunization with HEL in incomplete Freund's adjuvant (IFA) resulted in Th2-dominated immune responses characterized by HEL-specific secretion of IL-5 but not IFN-gamma.
673 9362523 In contrast, immunization with IFA-HEL plus CpG ODN switched the immune response to a Th1-dominated cytokine pattern, with high levels of HEL-specific IFN-gamma secretion and decreased HEL-specific IL-5 production.

683 9394185 CD4+ and CD8+ T1 cells, through the agency of IL-2 and IFN-gamma, direct the response towards cell-mediated immunity involving cytotoxicity and macrophage activation, whereas T2 cells, through the agency of IL-4 and IL-10, direct the response towards antibody production.
684 9394185 The two poles are counter-regulatory in that IFN-gamma inhibits antibody formation and IL-4 and IL-10 inhibit macrophage activation.
685 9394185 However, immune responses are not immutable and can be artificially driven towards one or other pole, for example IFN-gamma, IL-2 and IL-12 favour T1 responses, whereas IL-4 and IL-10 favour the T2 type.
686 9394185 For example, in experimental leishmaniasis, protective immune responses can be induced by the incorporation of genes for IL-2 and IFN-gamma into recombinant Salmonella typhimurium vectors and nucleic acid vaccines.

712 9398398 IL-12 and IL-10 were selectively or preferentially expressed by the regressor mice, and this correlated with the detection of functional type 1 reactivity in vivo (i.e., delayed-type hypersensitivity).
713 9398398 Other cytokines were produced by the regressor mice only in vitro (IFN-gamma) or were not detected at all with either type of tumor recipient (IL-4).
714 9429214 In particular, IL-12 influences the balance between the T-helper cells type 1 (TH1) and type 2 (TH2); it modulates macrophage responses through the control of interferon-gamma synthesis by TH1 cells; and, suppresses IgE class antibody production (has a suppressive effect on allergic reactions) and promotes a shift in the IgG subclasses.
715 9449711 Endogenous interleukin 4 is required for development of protective CD4+ T helper type 1 cell responses to Candida albicans.
716 9449711 In the early stage of systemic infection with virulent C. albicans, an unopposed interferon (IFN)-gamma response renders IL-4-deficient mice more resistant than wild-type mice to infection.
717 9449711 Defective IFN-gamma and IL-12 production, but not IL-12 responsiveness, was observed in IL-4-deficient mice that failed to mount protective T helper type 1 cell (Th1)-mediated acquired immunity in response to a live vaccine strain of the yeast or upon mucosal immunization in vivo.
718 9449711 In vitro, IL-4 primed neutrophils for cytokine release, including IL-12.
719 9449711 However, late treatment with exogenous IL-4, while improving the outcome of infection, potentiated CD4(+) Th1 responses even in the absence of neutrophils.
720 9449711 These findings indicate that endogenous IL-4 is required for the induction of CD4(+) Th1 protective antifungal responses, possibly through the combined activity on cells of the innate and adaptive immune systems.

727 9458095 Adjuvant use of recombinant murine IL-12 (rmIL-12) was examined in mice vaccinated with irradiated syngeneic tumor or allogeneic cells. rmIL-12 given to A/J mice vaccinated with irradiated SCK tumor cells engineered to secrete granulocyte/macrophage-colony-stimulating factor resulted in significantly better protection from tumor challenges 28 days after vaccination but, unexpectedly, severely compromised host protection 14 days after vaccination.
728 9464796 The role of interferon-gamma (IFN-gamma) and interleukin-12 in the mechanism of adjuvant action was also evaluated.
729 9464831 While IL-12 is key to their T helper cell (Th)1-promoting adjuvant activity, secretion of toxic levels of TNF-alpha is harmful in that it promotes toxic shock.

740 9469440 A novel population of both IFN-gamma- and IL-10-secreting human T cells that differentiate in the presence of exogenous IL-12 in vitro has recently been described.
741 9469440 However, in patients with Lyme disease, 27% of T cell lines secreted not only IFN-gamma but also IL-10, which was only observed in 0.6% of B. burgdorferi-reactive T cell lines generated from controls and in none of the tetanus toxoid-reactive T cell lines generated from either Lyme patients and controls.
742 9469440 Moreover, neutralizing anti-IL-12 mAbs inhibited the generation of the IFN-gamma/IL-10 population.
743 9469440 These data demonstrate that this novel population of IL-12-induced IFN-gamma/IL-10-secreting T cells is generated in response to chronic B. burgdorferi infection.

781 9525307 To apply IL-12 genes in gene therapy such as a DNA vaccine, a pIL-12 vector was constructed that contained two cytomegalovirus (CMV) promoters to drive the expression of p35 and p40 subunits, respectively.
782 9525307 In addition, a pscIL-12 vector was designed with a linker to fuse p35 cDNA with p40 cDNA to produce a single-chain IL-12 protein, ensuring not only that the expression of p35 and p40 subunits was equally expressed, but also that no free p40 subunits interfered with IL-12 activity.

859 9625536 The peritumoral injections of OK432 induced OK432-reactive CD4+ T cells in the draining lymph nodes, and their in vitro production of interferon gamma was thus significantly enhanced by restimulation with OK432-pulsed DC.

867 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.
868 9681415 To modify vectors, we introduced stretches of 20-60 dG residues into the pCMV-beta and pSG5rab.gp vectors and measured the ability of these plasmids to induce IL-12 and IFN-gamma production by murine splenocytes.

904 9686195 Nevertheless, in mice with a genetic disruption of the IFN gamma receptor, administration of SLAP + IL-12 induced levels of IFN gamma equal to those in wild-type mice, thus showing that in this model IL-12 can directly prime T cells independent of IFN gamma.
905 9686195 Elevated levels of IL-12 (p40 mRNA) were detected in the lymph nodes (LN) and the lungs of vaccinated mice, whilst treatment of vaccinated mice with anti-IL-12 antibodies decreased the ratio of IFN gamma:IL-4 secreted by in vitro-cultured LN cells.

911 9686610 Production of IL-12, detected in serum and spleen, was neither increased nor prolonged by injecting Abs to IL-10 or IL-4.
912 9686610 Mice lacking the receptors for TNF (TNFR-/- mice) were severely deficient in IL-12 production, suggesting a controlling role for TNF, which we have previously shown to be triggered by live, rather than dead, bacteria.
913 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.

1217 10068654 Similarly, immunization with GM-CSF/IL-12-transfected MDR sublines caused rejection of transplantation of both parental cells and the MDR sublines.
1218 10068654 Whereas MPC11 cells and their MDR variants were resistant to APO-1/CD95/Fas ligand, the immunization generated potent granzyme B/perforin-secreting cytotoxic T lymphocytes (CTLs) that were similarly effective against both parental and isogenic MDR cells.

1341 10228039 Cellular immunity to measles infection and vaccination may be limited in infants compared with adults as a result of less effective IFN-gamma and IL-12 production in response to measles Ags.
1342 10228039 IL-12, IFN-gamma, and T cell proliferation to measles in immunized infants.
1343 10228039 Measles binding to its monocyte receptor down-regulates IL-12 which is expected to diminish Th1-like cytokine responses, including IFN-gamma.
1344 10228039 We evaluated Ag-specific IL-12, IFN-gamma, and T cell responses of infants at 6 (n = 60), 9 (n = 46), or 12 mo (n = 56) of age and 29 vaccinated adults.
1345 10228039 IL-12 and IFN-gamma release by PBMC stimulated with measles Ag increased significantly after measles immunization in infants.
1346 10228039 IL-12 and IFN-gamma concentrations were equivalent in younger and older infants, but IL-12 concentrations were significantly lower in infants than in adults (p = 0.04).
1347 10228039 IL-12 production by monocytes was down-regulated by measles; the addition of recombinant human IL-12 enhanced IFN-gamma production by PBMC stimulated with measles Ag, but infant T cells released significantly less IFN-gamma than adult T cells under this condition.

1349 10228044 Addition of IL-2 or IL-7, but not IL-4 or IL-12, also restored proliferation of acute PBMC stimulated with anti-CD3.
1350 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.
1351 10352291 In mice inoculated with rVVlucIL-12 there is a rapid clearance of the virus, and this correlates with the induction of high levels of IL-12 and IFN-gamma in serum and spleen early after infection.
1352 10352291 An enhancement of about 2-fold in the number of anti-gp160 IFN-gamma-secreting CD8+ T cells was observed in mice inoculated with rVVenvIL-12, when a dose of 1 x 107 PFU/mouse was used, but this enhancement was not observed when mice were given 5 x 107 PFU.
1353 10359214 This response was augmented following the pretreatment of KS-CD80 cells with interferon-gamma and tumor necrosis factor-alpha.
1354 10359214 Interleukin-4 (IL-4), IL-7, and IL-12 further increased T-cell expansion.
1355 10359823 Immunostimulatory oligodeoxynucleotides promote protective immunity and provide systemic therapy for leishmaniasis via IL-12- and IFN-gamma-dependent mechanisms.
1356 10359823 To determine whether the therapeutic protection provided by CpG-ODN depended on IL-12 and IFN-gamma production, both IFN-gamma-deficient BALB/c mice and BALB/c mice treated with neutralizing anti-IL-12 mAb were first inoculated with Leishmania and then treated with either CpG-ODN, ODN, or PBS.

1364 10361129 It was demonstrated that major histocompatibility complex (MHC)-unrestricted cytotoxic T cells can recognize epitopes of the MUC1 protein core localized in the tandem repeat domain.
1365 10361129 There is increasing evidence now that MHC-restricted T cells can also be induced after immunization with the MUC1 protein or segments of the core tandem repeat.
1366 10361129 The addition of a Pan-HLA-DR binding peptide PADRE as a T-helper epitope during the in vitro priming resulted in an increased cytotoxic activity of the MUC1-specific CTL and a higher production of cytokines such as interleukin-12 and interferon-gamma in the cell cultures, demonstrating the importance of CD4 cells for an efficient CTL priming.
1367 10365790 At the laboratory, the duplicate specimens were weighed and tested in replicate wells to determine the concentration of two cytokines (IL-10 and IL-12) and two immunoglobulin isotypes (IgG and IgA).
1368 10365790 Age and reproductive status were associated with all four immune measures; women over 50 years of age and those who were postmenopausal had increased concentrations of IL-10, IL-12, IgG, and IgA.

1376 10382739 CT had no inhibitory effects on lipopolysaccharide/IFN-gamma-induced IL-12 mRNA expression or IL-12 production.
1377 10382760 In vitro derived DC were infected with BCG, which induced their maturation, as shown by the increased expression of MHC class II antigens, CD80 and CD86 co-stimulatory molecules.
1378 10382760 The synthesis of mRNA for IL-1, IL-6, IL-12, IL-10 and IL-1 receptor antagonist was also enhanced.
1379 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.
1380 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.
1381 10390075 Upregulation of antitumor immunity by IL-12 gene-transfected AK-5 tumor cells in vivo.
1382 10390075 We have earlier demonstrated a significant role for IL-12 in the regression of a rat histiocytic tumor, AK-5.
1383 10390075 Analysis of the serum samples from animals injected with the IL-12 gene-transfected AK-5 cells on different days revealed a significant increase in circulatory IL-12, interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha and antitumor antibodies, all of which contributed to the reduction in tumor mass.
1384 10390075 Similarly, intraperitoneal transplantation of IL-12 gene-transfected tumor cells in syngeneic Wistar rats induced a significant increase in cellular cytotoxicity, with a concomitant reduction in circulatory IL-12 (p40) protein.

1406 10395683 This immunity is directed against the Plasmodium spp. parasite developing within the host hepatocyte and for a number of years has been presumed to be mediated directly by CD8+ CTL or indirectly by IFN-gamma released from CD8+ T cells.
1407 10395683 In this paper, in BALB/c mice, we establish that after immunization with irradiated sporozoites or DNA vaccines parasite-specific CD8+ T cells trigger a novel mechanism of adaptive immunity that is dependent on T cell- and non-T cell-derived cytokines, in particular IFN-gamma and IL-12, and requires NK cells but not CD4+ T cells.
1408 10397174 Cytometric analysis showed that they constitutively expressed the cell surface markers CD45, CD1 1b, MHC class II, F4/80, N418, B7-2 and ICAM1.
1409 10397174 Despite both cell lines expressing Thy-1 only, the AG116 show CD4 but both were negative for CD8 and B220.
1410 10397174 In addition to a basal production of IL-6, the cell lines were found to increase their synthesis of IL-6 and IL-12 p40 after interaction with T cells in a similar way as mature wtDCs.
1411 10400824 When IL-12 was replaced by other cytokines acting on T cells or antigen-presenting cells, such as IFN-gamma, IL-2, IL-6, IL-7, GM-CSF or MCP-3, no significant enhancing effect was observed.
1412 10410657 Including cytokines such as IL-2, IL-12, IFN, TNF or monoclonal antibodies, they have been widely used as biological response modifiers (BRM).
1413 10415076 The administration of GM-CSF or IL-12 also resulted in a decrease in circulating precursors compared with the administration of peptide alone, though not as great a decrease as that seen with IL-2.
1414 10421650 B7-1 (CD80)-gene transfer combined with interleukin-12 administration elicits protective and therapeutic immunity against mouse hepatocellular carcinoma.
1415 10421650 To try to find a way to prevent this, we examined the combined effectiveness of B7-1 (CD80)-gene transfer and interleukin-12 (IL-12) on the induction of protective antitumor immunity against poorly immunogenic BNL1ME A.7R. 1 (BNL) mouse HCC cells.
1416 10421650 In vivo lymphocyte subset depletion study indicated that the combined antitumor effect was dependent on the presence of both CD8(+) and CD4(+) T cells.

1420 10423959 Diverse cytokines are known to play an important role in anti-TB cell-mediated immunity, including IL-2, IL-12, IL-18 and IFN-gamma.
1421 10427987 In this study, we demonstrate that porcine relaxin, at concentrations ranging from 10(-10) to 10(-6) M, favors the in vitro development of human antigen-specific T cells into Th1-like effectors and enhances both IFN-gamma mRNA expression and IFN-gamma production by established human T cell clones.
1422 10427987 The promoting effect of relaxin on the development of IFN-gamma-producing cells was not due to a relaxin-induced release of IL-12 and/or IFN-alpha by antigen-presenting cells.
1423 10438922 Priming MHC-I-restricted cytotoxic T lymphocyte responses to exogenous hepatitis B surface antigen is CD4+ T cell dependent.
1424 10438922 Priming of this CTL response by exogenous HBsAg required CD4+ T cell "help" and IL-12: this CTL response could be neither induced in mice depleted of CD4+ T cells by in vivo Ab treatment, nor in (CD4+ T cell-competent or CD4+ T cell-depleted) IL-12-unresponsive STAT4-/- knockout BALB/c mice.
1425 10438922 In vivo priming of the well-characterized CD8+ CTL response to HBsAg in "high responder" BALB/c mice either by exogenous surface lipoprotein particles or by DNA vaccination is thus CD4+ T cell dependent.
1426 10438930 In this study four murine IL-12 naked DNA expression plasmids (pIL-12), containing both the p35 and p40 subunits, were shown to induce systemic biological effects in vivo after intradermal injection.
1427 10438930 Three of the four IL-12 expression vectors augmented NK activity and induced expression of the IFN-gamma and IFN-gamma-inducible Mig genes.
1428 10438930 Both IL-12 p70 heterodimer and IFN-gamma proteins were documented in the serum within 24 h after intradermal injection of the pIL-12o- plasmid, which also induced the highest level of NK activity in the spleen and liver among the IL-12 constructs.
1429 10438930 Finally, injection of the pIL-12o- into BALB/c IL-12 p40-/- mice also resulted in a biphasic pattern of IL-12 p70 appearance in the serum, and induced IFN-gamma protein and activated NK lytic activity in liver and spleen.

1442 10447773 Although MSP119 alone could induce a small but detectable T-cell response, which included interleukin-4 (IL-4) secretion, this response was significantly increased by the presence of IL-2.
1443 10447773 In addition, IL-4 was shown to synergize with IL-2 for the induction of antigen-specific T-cell responses.
1444 10447773 If interferon-gamma (IFN-gamma), IL-12, or neutralizing anti-IL-4 antibody was present at the time of priming, the T-cell responses were abolished.
1445 10447773 Parasite-specific immunoglobulin G (IgG) could be detected after secondary restimulation with MSP119, IL-10 and anti-CD40 monoclonal antibody in cultures containing MSP119 primed T cells, autologous B cells, IL-2 and IL-4.
1446 10448141 The former is largely mediated via CD8(+) T cells and involves IFN-gamma, nitric oxide, IL-12 and natural killer cells; the latter varies (in different hosts and with different parasites) but is largely mediated by antibody, helper T cells, nitric oxide and gammadelta T cells.
1447 10455415 IFN-gamma production of hepatic lymphocytes when they were cocultured with the parental cells was significantly augmented in mice vaccinated with the IL-12 transfectant compared with the control.
1448 10456897 RDA did not alter the H. felis-specific immunoglobulin G1 (IgG1), IgG2a, and IgA responses in the serum but was associated with an increase in gamma interferon (IFN-gamma)-producing CD8(+) spleen cells.
1449 10456897 To determine if IFN-gamma or Th1 cytokines were involved in the response to RDA, we examined RDA treatment of H. felis infection in mice lacking either IFN-gamma or interleukin-12 (IL-12).
1450 10456897 Thus, viral infection of mice chronically infected with H. felis led to a significant decrease in H. felis colonization in an IFN-gamma- and IL-12-dependent manner.

1454 10460097 Several immune amplifiers, such as interferon-gamma (IFN-gamma), interleukin-2 (IL-2), and interleukin-12 (IL-12) have undergone pilot testing.
1455 10473523 Cytokine reconstitution experiments demonstrated that while addition of recombinant IL-12 (rIL-12) plus anti-IL-4 restored PPD-specific responses in the NN group, it had no effect in the PN group.
1456 10476222 Using the well characterized beta-galactosidase (beta gal) model Ag system we find that both in vivo gene transfer systems elicit potent and long-lasting anti-beta gal-specific CD8+ and CD4+ T cell responses.
1457 10476222 Since viral infections are generally associated with the production of large amounts of IFN-alpha and IL-12, we investigated whether administration of expression plasmids encoding these Th1-associated cytokines along with antigen-encoding cDNA can influence the nature of the immune response resulting from gene gun immunization.
1458 10476222 We observed that co-delivery of IFN-alpha or IL-12 resulted in increased production of anti-beta gal gamma 2a antibodies.
1459 10476222 Using the well characterized beta-galactosidase (beta gal) model Ag system we find that both in vivo gene transfer systems elicit potent and long-lasting anti-beta gal-specific CD8+ and CD4+ T cell responses.

1462 10477566 DCs incubated with recombinant S. gordonii were much more efficient than DCs pulsed with soluble C-fragment of tetanus toxin at stimulating specific CD4+ T cells as determined by cell proliferation and IFN-gamma release.
1463 10477566 In particular, S. gordonii dose-dependently up-regulated expression of membrane molecules (MHC I and II, CD80, CD86, CD54, CD40, CD83) and reduced both phagocytic and endocytic activities.
1464 10477566 Furthermore, bacteria promoted in a dose-dependent manner DC release of cytokines (IL-6, TNF-alpha, IL-1beta, IL-12, TGF-beta, and IL-10) and of the chemokines IL-8, RANTES, IFN-gamma-inducible protein-10, and monokine induced by IFN-gamma.
1465 10479116 Mice were immunized intranasally (in) with an influenza vaccine consisting of soluble hemagglutinin (H1) and neuraminidase (N1) plus IL-12.
1466 10479116 This treatment resulted in elevated levels of lung and splenic interferon-gamma and IL-10 mRNA.
1467 10487139 To test the possibility, plasmid vector containing granulocyte macrophage-colony stimulation factor (GM-CSF) and interleukin-12 (IL-12) genes, which are known as one of the most potent anti-tumor cytokines, were constructed and injected into mice together with syngeneic tumor cells.

1469 10496906 We found that CT and LPS differentially regulated the expression of interleukin-12 (IL-12) and CD80-CD86 but not that of IL-1beta.
1470 10496906 LPS and CT each induced IL-1beta expression in macrophages, while only LPS induced IL-12 and only CT induced CD80-CD86.
1471 10496906 These differences were markedly potentiated in gamma interferon (IFN-gamma)-treated macrophages, in which LPS potently induced IL-12 and CD80-CD86 expression.
1472 10496906 In contrast, IFN-gamma treatment had no effect on the expression of IL-1beta.

1488 10505112 The colon adenocarcinoma C26, carrying two endogenous tumor-associated antigens (TAA) recognized by CTL, has been transduced with the gene coding for the human folate receptor alpha (FR alpha) as an additional antigen in order to study the efficacy of vaccination against a tumor expressing multiple antigens.
1489 10505112 A dicistronic vector was used to transduce the IL-12 genes to create C26/IL-12/FR alpha that has been used as a cellular vaccine to treat mice bearing lung metastases of C26/FR alpha.
1490 10505112 CD8 from responder mice were characterized to release high levels of granulocyte-macrophage (GM)-CSF upon antigen stimulation.
1491 10505112 Immunoselection against FR alpha antigen was not observed in tumors from non-vaccinated controls and from CD8-depleted vaccinated mice.
1492 10505112 These results indicate that CD8 T cell-mediated immunoselection and production of GM-CSF are determining factors for the efficacy of tumor vaccines.
1493 10510336 The important T-cell stimulatory cytokine IL-12 or the proinflammatory cytokines IL-1beta or TNF-alpha were not detected or were only minimally detected.
1494 10510336 Finally, monocytes pretreated with HRV-14 were greatly inhibited in their production of IL-12 upon stimulation with IFN-gamma/LPS.
1495 10525444 Iscoms prominently enhance the antigen targeting, uptake, and activity of antigen presenting cells including dendritic and B cells and macrophages resulting in the production of proinflammatory cytokines, above all interleukin (IL)-1, IL-6, and IL-12.
1496 10525444 The expression of costimulatory molecules major histocompatibility complex (MHC) class II, B7.1 and B7.2, is also enhanced.
1497 10525444 Iscoms enhance the Th1 type of response with increased production of IL-2 and interferon gamma.
1498 10525444 IL-4, IL-2, and interferon gamma (IFNgamma) together with the beta chemokines MIP-1alpha and MIP-1beta correlated with protection against challenge infection with a chimeric virus (simian immunodeficiency virus-human immunodeficiency virus).
1499 10525447 Interleukin-12 (IL-12) is a cytokine whose main effect is to drive Th-cell differentiation throughout a T helper type 1 cell type of response, thus inducing interferon gamma (IFNgamma) and favoring a switch from Ig to IgG2a.
1500 10525448 Interleukin (IL)-18 is a newly discovered cytokine, structurally similar to IL-1, with profound effects on T-cell activation.
1501 10525448 Formerly called interferon (IFN) gamma inducing factor (IGIF), IL-18 is the new name of a novel cytokine that plays an important role in the T-cell-helper type 1 (Th1) response, primarily by its ability to induce IFNgamma production in T cells and natural killer (NK) cells.
1502 10525448 Mice deficient in IL-18 have suppressed IFNgamma production despite the presence of IL-12 IL-18 is related to the IL-1 family in terms of structure, receptor family, and function.
1503 10525448 In terms of structure, IL-18 and IL-1beta share primary amino acid sequences of the so-called "signature sequence" motif and are similarly folded as all-beta pleated sheet molecules.
1504 10525448 Also similar to IL-1beta, IL-18 is synthesized as a biologically inactive precursor molecule lacking a signal peptide which requires cleavage into an active, mature molecule by the intracellular cysteine protease called IL-1beta-converting enzyme (ICE, also called caspase-1).
1505 10525448 The activity of mature IL-18 is closely related to that of IL-1.
1506 10525448 IL-18 induces gene expression and synthesis of tumor necrosis factor (TNF), IL-1, Fas ligand, and several chemokines.
1507 10525448 This IL-18R complex is made up of a binding chain termed IL-18Ralpha, a member of the IL-1 receptor family previously identified as the IL-1 receptor-related protein (IL-1Rrp), and a signaling chain, also a member of the IL-1R family.
1508 10525448 The IL-18R complex recruits the IL-1R-activating kinase (IRAK) and TNFR-associated factor-6 (TRAF-6) which phosphorylates nuclear factor kappaB (NFkappaB)-inducing kinase (NIK) with subsequent activation of NFkappaB.
1509 10525448 Thus on the basis of primary structure, three-dimensional structure, receptor family, signal transduction pathways and biological effects, IL-18 appears to be a new member of the IL-1 family.
1510 10525448 Similar to IL-1, IL-18 participates in both innate and acquired immunity.

1571 10547157 Cloning of a cDNA encoding bovine interleukin-18 and analysis of IL-18 expression in macrophages and its IFN-gamma-inducing activity.
1572 10547157 Interleukin-18 (IL-18) is a recently described cytokine that enhances interferon-gamma (IFN-gamma) production, either independently or synergistically with IL-12.
1573 10547157 Human recombinant IL-18 (rHuIL-18) induced IFN-gamma production by PHA-stimulated peripheral blood mononuclear cells (PBMC), which was potentiated by rHuIL-12.
1574 10547157 Antigen-specific T cell lines demonstrated IL-18-dependent enhancement of IFN-gamma production, indicating that bovine T cells are one of the leukocyte subsets that respond to IL-18.
1575 10547157 Analysis of IL-18 expression and its ability to induce IFN-gamma production by bovine lymphocytes are important considerations for understanding mechanisms of protective immunity and designing vaccines for intracellular pathogens.
1576 10555997 Previously, we demonstrated that a novel low-molecular-weight synthetic immune response modifier, R-848, induces IL-12 and IFN-alpha secretion from monocytes and macrophages.
1577 10555997 Characteristic of dendritic cell maturation, R-848 treatment induces cell surface expression of CD83 and increases cell surface expression of CD80, CD86, CD40, and HLA-DR.
1578 10555997 Additionally, R-848 induces cytokine (IL-6, IL-12, TNF-alpha, IFN-alpha) and chemokine (IL-8, MIP-1alpha, MCP-1) secretion from dendritic cells.
1579 10555997 Previously, we demonstrated that a novel low-molecular-weight synthetic immune response modifier, R-848, induces IL-12 and IFN-alpha secretion from monocytes and macrophages.
1580 10555997 Characteristic of dendritic cell maturation, R-848 treatment induces cell surface expression of CD83 and increases cell surface expression of CD80, CD86, CD40, and HLA-DR.

1582 10559341 We now show that infection by rAd enhances the immunostimulatory capacity of immature human monocyte-derived DC through the upregulation of the costimulatory molecules CD80, CD86, and CD40 and the major histocompatibility complex class I and II molecules.
1583 10559341 Although rAd infection fails to induce the secretion of interleukin-12 (IL-12) and only marginally induces the expression of the DC maturation marker CD83, it acts in synergy with CD40 triggering in rendering DC fully mature. rAd-infected DC triggered through CD40 produce more IL-12 and are more efficient in eliciting T-helper type 1 responses than DC activated by CD40 triggering only. rAd lacking one or more of the early regions, E1, E2A, E3, and E4, which play an important role in virus-host cell interactions are equally capable of DC activation.

1585 10569735 Heat-killed Brucella abortus promotes secretion of Th1-inducing cytokines such as interleukin-12 (IL-12) and IFN-gamma and has been used as a carrier to induce Th1 responses to vaccines.

1619 10590071 In contrast, AML cells genetically modified to express IL-12 (IL12-AML) using murine stem cell virus (MSCV) p40 + p35 elicit very potent antileukemic activity.
1620 10590071 In vivo depletion of IL-12, interferon-gamma (IFN-gamma), or CD8(+) T cells after injections with live IL12-AML cells abrogates completely the antileukemia immune responses.
1621 10590071 Studies on the in vitro effects of IFN-gamma on AML cells demonstrate enhanced expression of major histocompatibility complex (MHC) and accessory molecules and induction of the costimulatory molecules B7.1 and B7.2, but no significant direct antiproliferative effect. (51)Cr release assays show that rejection of live IL12-AML cells supports the development of long-lasting leukemia-specific cytotoxic T lymphocyte (CTL) activity.
1622 10590071 In contrast, AML cells genetically modified to express IL-12 (IL12-AML) using murine stem cell virus (MSCV) p40 + p35 elicit very potent antileukemic activity.

1633 10601552 Human tumor antigens when presented appropriately (with costimulatory molecules and with IL-2, IL-12) break the host's natural tolerance toward its tumor and induce rejection strength immune reactions even in patients with metastatic disease.
1634 10601552 For successful active specific immunization against human cancers the understanding of the immunoevasive maneuvers of the tumor cell (through FasL --> Fas; TRAIL; CD40L --> CD40; TGFbeta etc. systems) is essential.
1635 10602382 The antitumor effect correlated well with a strong and rapid proinflammatory cytokine (TNF-alpha, IL-12 and IFN-gamma) response.
1636 10605015 Vaccination with heat-killed Listeria as adjuvant reverses established allergen-induced airway hyperreactivity and inflammation: role of CD8+ T cells and IL-18.
1637 10605015 Asthma is a respiratory disorder characterized by airway hyperreactivity (AHR) and inflammation and is associated with high serum IgE and overproduction of IL-4, IL-5, and IL-13 by allergen-specific Th2 cells.
1638 10605015 HKL as adjuvant also dramatically inhibited airway inflammation, eosinophilia, and mucus production, significantly reduced Ag-specific IgE and IL-4 production, and dramatically increased Ag-specific IFN-gamma synthesis.
1639 10605015 The inhibitory effect of HKL on AHR depended on the presence of IL-12 and CD8+ T cells and was associated with an increase of IL-18 mRNA expression.
1640 10606974 Th1-biased immune responses induced by DNA-based immunization were substantially upregulated by a codelivery of an ectopic IFN-gamma expression system, and this augmentation was mediated via action on professional antigen presenting cells to upregulate IL-12 production.
1641 10607307 Single-chain porcine interleukin-12 was bioactive in vitro on both human and porcine cells as measured by its ability to induce proliferation of lymphoblasts and interferon-gamma secretion by lymph node cells.

1650 10607486 After a 6-h incubation, phenotypic analysis of control-, imiquimod-, or R-848-treated LC indicated that such antigen-presenting cells were in an "intermediate" state of maturation (CD1a(+), HLA-DR, DP, DQ(bright+), CD40(low+), CD86(high+), and CD80(low+)).
1651 10607486 RNase protection assays demonstrated that either imiquimod or R-848 treatments increased steady-state transcripts encoding for IL-12 p40, IL-1beta, TNF-alpha, and IL-1 receptor antagonist by LC.
1652 10614729 Beta-gal in alum induced IgG1 and IgE antibodies and the CD4+ T cells from these mice secreted interleukin 4 (IL-4) and IL-5 but no interferon-gamma (IFN-gamma) after in vitro antigen stimulation.
1653 10614729 In contrast, mice immunized with pCMV-LacZ formed predominantly IgG2a antibodies and their CD4+ T cells secreted IFN-gamma but no IL-4 and IL-5.
1654 10614729 Boosting of mice primed with beta-gal in alum with pCMV-LacZ resulted in a 75% decrease in the IgE antibody titer within 6 weeks and IgG2a antibody formation and CD4+ T cells that secreted IFN-gamma in amounts similar to T cells from pDNA primed mice.
1655 10614729 As shown by adoptive cell transfer, both CD4+ and CD8+ T cells from pDNA immunized mice inhibited an IgE response to beta-gal in alum in the recipient mice. pDNA immunization also inhibited the eosinophilic infiltration of the lung of ovalbumin (OVA) immunized mice after OVA inhalation challenge in an animal model of the late phase reaction.

1710 10678945 A mixture of well-defined recombinant antigens together with an adjuvant that preferentially stimulates specific gamma interferon (IFN-gamma)-secreting helper type 1 CD4(+) T cells (Th1 cells) presents a rational option for a vaccine against leishmaniasis.
1711 10678945 A mixture of three antigens (glycoprotein 63, cysteine proteinases, and a membrane-bound acid phosphatase), which are all expressed in amastigotes, the mammalian stage of the parasite, were used for the immunization of C57BL/6 mice in combination with six adjuvants (interleukin 12 [IL-12], Detox, 4'-monophosphoryl lipid A, QS-21, Mycobacterium bovis BCG, and Corynebacterium parvum).
1712 10678945 Further studies using these two adjuvants showed that a similar protective effect was observed with a mixture of the corresponding native proteins, and mice which had controlled the infection showed a preponderance of IFN-gamma-secreting CD4(+) T cells in the lymph nodes draining the lesion.
1713 10678966 Susceptibility of BALB/c mice to Leishmania major infection has been correlated to the preferential development of Th2 CD4 T cells through an early production of interleukin 4 (IL-4) by a restricted population of CD4 T cells which react to a single parasite antigen, LACK (stands for Leishmania homologue of receptors for activated C kinase).
1714 10678966 Experimental vaccination with LACK can redirect the differentiation of CD4(+) T cells towards the Th1 pathway if LACK is coadministrated with IL-12.
1715 10678966 After a single injection of LACK-expressing L. monocytogenes, IL-12/p40 transcripts showed a rapid burst, and peaks of gamma interferon (IFN-gamma)-secreting LACK-specific Th1 cells were detected around day 5 in the spleens and livers of mice of both strains.
1716 10678966 Thus, our results demonstrate that, in addition of its recognized use for the induction of effector CD8 T cells, L. monocytogenes can also be used as a live recombinant vector to favor the development of potentially protective IFN-gamma-secreting Th1 CD4 T lymphocytes.

1720 10678966 Thus, our results demonstrate that, in addition of its recognized use for the induction of effector CD8 T cells, L. monocytogenes can also be used as a live recombinant vector to favor the development of potentially protective IFN-gamma-secreting Th1 CD4 T lymphocytes.
1721 10687141 Although a comparable percentage of DCs expressing CD86+ (B7-2), CD40+, and HLA-DR+ were detected in both cultures, higher expression levels were detected in DCs derived from bulk culture (CD86 = MRLFI 3665.1 versus 2662.1 on day 6; CD40 = MRLFI 1786 versus 681.2 on day 6; HLA-DR = MRLFI 6018.2 versus 3444.9 on day 2).
1722 10687141 Cytokines involved in DC maturation were determined by polymerase chain reaction demonstrating interleukin-6 (IL-6), IL-12, interferon-gamma, granulocyte-macrophage colony-stimulating factor, and tumor necrosis factor-alpha mRNA expression by bulk culture cells during the entire 9-day culture period.
1723 10687141 Concurrently, CD3+ CD56-, CD3+ CD25+, and CD3+ TCR+ cell populations increased and cytotoxicity against autologous renal cell carcinoma tumor target was induced.
1724 10689136 The generation of DC from blood monocytes in response to GM-CSF and IL-4 treatment was similar in cells from young and old persons.
1725 10689136 The DC population thus obtained had a typical dendritic morphology and expressed DC surface markers, such as HLA class II, CD1a, CD11c, CD54, CD80 and CD86, but not CD14 for a period of up to three weeks in culture.
1726 10689136 DC from young and old persons produced IL-12 and TNF-alpha and responded equally well to maturation-inducing stimuli.
1727 10689137 The response of NK cells from elderly individuals to IL-2 or other cytokines is also decreased in terms of proliferation, expression of CD69 and killing of NK-resistant cell lines.
1728 10689137 Furthermore early IFN-gamma and chemokine production in response to IL-2 or IL-12 is also decreased.
1729 10689137 However aging does not significantly alter other NK cell functions such as TNF-alpha production or perforin induction in response to IL-2.

1759 10706701 From a clinical point of view, the effects of IP-10 permit one to lower the required gene transfer level of IL-12, thus preventing dose-dependent IL-12-mediated toxicity while improving the therapeutic efficacy of the elicited antitumor response.
1760 10706961 Due to the synergistic effects of IL-12 and IL-18, and to their importance in establishing a Th1 type immune response, we investigated the potential of a combined administration of both cytokines as an adjuvant for recombinant antigens.
1761 10706961 By co-adsorption of this antigen on alum in the presence of IL-12 and IL-18, we demonstrate that IL-18 enhances the effects of IL-12 in inducing an antigen-specific Th1 type CD4(+) T cell response as well as high titres of IgG1, IgG2a, and IgG2b antibodies.

1764 10708883 IFN-gamma, TNF-alpha, IL-10 and IL-12 (ELISA).
1765 10708883 In similar experiments, a significant increase in the cytolytic activity of HPNK cells was elicited by S. typhi Ty2 but not by mutant strain MEI028; neither of the cytokines assayed (IFN-gamma and TNF-alpha) was detected in the supernatant.
1766 10708883 Incubation with S. typhi Ty2 or MEI028 elicited significant expression of CD69, an early marker of NK cell activation, in PBMC but not in HPNK cell samples (flow cytometry); in similar experiments, the expression of CD16/56 and activation marker CD25 remained essentially unchanged.
1767 10717256 Changes of the quasispecies population are more pronounced after initiation of treatment with IFN-a or interleukin-12 than during the natural course of disease.
1768 10722593 Despite this strong protective response, LPS purified from F. tularensis LVS did not activate murine B cells for proliferation or polyclonal immunoglobulin secretion, nor did it activate murine splenocytes for secretion of interleukin-4 (IL-4), IL-6, IL-12, or gamma interferon (IFN-gamma).
1769 10723942 We propose that cell mediated immunity comprises two separate elements; protective immunity, driven by IL-12 and IFN; and DTH, mediated by TNF and driven by chemokines.
1770 10723942 These include gamma delta T cells, which we believe control the inflammatory influx of cells; CD4+ NK cells, which may play a role in focussing lymphocytes into lung granulomas; and CD8 T cells, which play a currently undefined role after initial expression of immunity and establishment of chronic disease in the lungs has ensued.
1771 10725381 Potent induction of long-term CD8+ T cell memory by short-term IL-4 exposure during T cell receptor stimulation.
1772 10725381 Using a MHC-compatible adoptive transfer system, we show here that a short, 3-day IL-4 but not IL-2 or IL-12 exposure during in vitro T cell receptor stimulation of naive CD8(+) T cells induced long-lasting in vivo memory.
1773 10725381 Such long-term memory CD8(+) T cells expressed antigen-specific cytotoxicity and the potential for IFN-gamma and IL-4 production.
1774 10725728 Immunization and treatment with IL-12 within 24 h of birth resulted in elevated expression of IFN-gamma, IL-10, and IL-15 mRNA in the spleens of newborn mice compared with animals exposed to vaccine only.
1775 10725728 In addition, these animals showed dramatic increases in IFN-gamma-, IL-2-, and IL-4-secreting cells, and in IgG2a Ab levels upon adult challenge compared with mice primed with vaccine alone.
1776 10728798 Emerging new therapies include inhibitors of viral enzymes (protease, helicase and polymerase), cytokines (IL-12 and IL-10), antisense oligonucleotides and ribozymes.
1777 10738585 If the DNA contains these immune stimulatory 'CpG-S motifs', the cells become activated within minutes and begin producing pro-inflammatory cytokines such as IL-6 and IL-12 and upregulate expression of co-stimulatory molecules.
1778 10741861 Serum antigen-specific antibody (Ab) responses were enhanced when either IL-6 or IL-12 was mucosally administered with a protein antigen, while only IL-12 induced antigen-specific mucosal IgA Ab responses.
1779 10741861 Mucosal IL-6 and IL-12 also affected the type of Th cell responses induced by CD4+ T cells from mice that received IL-12 secreted larger amounts of IFN-gamma and IL-6 when compared with mice nasally treated with IL-6.
1780 10741861 Mixed antigen-specific Th1 -and Th2-type CD4+ T cell responses were induced in the systemic compartment by both lymphotactin and the mixture of HNP-1, HNP-2, and HNP-3 defensins.
1781 10741861 In summary, these studies clearly show that IL-12 and lymphotactin are able to trigger S-IgA Ab responses and provide new avenues for the design of safe and targeted mucosal vaccines.

1790 10757021 Coinjection of the CEA vector with a vector encoding either interferon-gamma (IFN gamma) or IL-12 promoted IgG2a isotype anti-CEA antibody production, anti-CEA/P815 CTL activity and greater resistance to CEA/P815 tumor challenge.
1791 10757021 As well, CEA/P815-stimulated IFN gamma secretion in vitro was increased, but IL-4 diminished, consistent with a T-helper type 1 (Th1) response.
1792 10757021 In contrast, coinjection of the CEA vector with an IL-4 vector increased IgG1 production, but reduced CTL activity and resistance to tumor challenge.
1793 10757021 The latter treatment inhibited CEA/P815-dependent IFN gamma production but enhanced IL-4 secretion, consistent with a Th type 2 (Th2) response.
1794 10757021 Antitumor immunity was enhanced when the CEA and IL-12 plasmids were coinjected at the same muscle site, but not at separate sites despite increased serum IL-12 levels.
1795 10758564 Recently designed tumor vaccines are capable of stimulating antitumor immune responses that recognize tumor cell epitopes or that have the potential to act synergistically with cytokines such as interleukin-2 and interleukin-12.
1796 10763709 Strong IL-5 and IL-13 responses in young mice, and limited IL-12 and IFN-gamma release capacity by early life APC and T cells both in young mice and infants, could contribute to the severity of infections with intracellular pathogens in early life.
1797 10768993 Mice vaccinated with BCG plus IL-12 or CpG ODN showed enhanced production of IFN-gamma compared with mice vaccinated with BCG alone.
1798 10772532 Since IL-12 consists of two subunit genes, p35 and p40, SHIVs with one or both of these genes were constructed.
1799 10772532 The production of IL-12 by the coinfection reached 800 pg/ml, and IL-12 was detected after serial passage in cell cultures, although this amount of IL-12 heterodimer was 150-1500 times less than that of the p40 subunits.

1802 10782864 Immunotherapy with vaccines combining MHC class II/CD80+ tumor cells with interleukin-12 reduces established metastatic disease and stimulates immune effectors and monokine induced by interferon gamma.
1803 10782864 Two such mouse models are used in this report to demonstrate the therapeutic efficacy and to probe the mechanisms of a novel combination immunotherapy consisting of the cytokine interleukin-12 (IL-12) combined with a previously described vaccine based on MHC class II, CD80-expressing cells.
1804 10782864 C57BL/6 mice with 7-day established intravenous B16 melF10 lung metastases show a similar response following immunotherapy with IL-12 plus a vaccine based on B16 MHC class II, CD80-expressing cells.
1805 10782864 In both systems the combination therapy of cells plus IL-12 is more effective than IL-12 or the cellular vaccine alone, although, in the 4T1 system, optimal activity does not require MHC class II and CD80 expression in the vaccine cells.
1806 10782864 The cell-based vaccines were originally designed to activate tumor-specific CD4+ T lymphocytes specifically and thereby provide helper activity to tumor-cytotoxic CD8+ T cells, and IL-12 was added to the therapy to facilitate T helper type 1 lymphocyte (Th1) differentiation.
1807 10782864 In vivo depletion experiments for CD4+ and CD8+ T cells and natural killer (NK) cells and tumor challenge experiments in beige/nude/XID immunodeficient mice demonstrate that the therapeutic effect is not exclusively dependent on a single cell population, suggesting that T and NK cells are acting together to optimize the response.
1808 10782864 IL-12 may also be enhancing the immunotherapy via induction of the chemokine Mig (monokine induced by interferon gamma), because reverse PCR experiments demonstrate that Mig is present in the lungs of mice receiving therapy and is most likely synthesized by the tumor cells.

1885 10838666 Eight and 13 MRCC patients received IL-2 plus IFN-alpha or IL-12 immunotherapy, respectively.
1886 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.
1887 10838666 Morphologic and phenotypical analyses revealed immature DCs with low levels of CD1a or CD83 expression throughout therapy with BRMs.
1888 10838666 IL-12 expression levels under IFN-gamma and CD40L stimulation were significantly lower in MDDC cultures from patients with MRCC compared with healthy volunteers.
1889 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.
1890 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.
1891 10841077 We observed that coimmunization with IL-8, gammaIP-10, and MIP-1alpha genes increased the antibody response.
1892 10841077 We also found that coinjection with IL-8, gammaIP-10, and RANTES resulted in a dramatic enhancement of T helper (Th) proliferation response.
1893 10841077 This enhancement of CTL responses observed from the coinjection with RANTES was CD8+ T cell dependent.
1894 10858219 Beryllium is associated with a human pulmonary granulomatosis characterized by an accumulation of CD4(+) T cells in the lungs and a heightened specific lymphocyte proliferative response to beryllium (Be) with gamma interferon (IFN-gamma) release (i.e., a T helper 1 [Th1] response).
1895 10858219 If interleukin-12 (IL-12) is given during in vivo sensitization with SLA, markedly increased IFN-gamma production and decreased IL-4 production are detected.
1896 10858219 We show here that when beryllium sulfate (BeSO(4)) was added during in vivo sensitization of BALB/c mice with SLA and IL-12, significantly increased IFN-gamma production and decreased IL-4 production from lymph node and spleen cells were detected upon in vitro SLA restimulation.
1897 10858219 In vivo, when Be was added to SLA and IL-12 for sensitization of BALB/c mice, more effective control of Leishmania infection was achieved.
1898 10858219 Beryllium is associated with a human pulmonary granulomatosis characterized by an accumulation of CD4(+) T cells in the lungs and a heightened specific lymphocyte proliferative response to beryllium (Be) with gamma interferon (IFN-gamma) release (i.e., a T helper 1 [Th1] response).

1901 10858219 In vivo, when Be was added to SLA and IL-12 for sensitization of BALB/c mice, more effective control of Leishmania infection was achieved.

1905 10858219 In vivo, when Be was added to SLA and IL-12 for sensitization of BALB/c mice, more effective control of Leishmania infection was achieved.
1906 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.
1907 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.
1908 10864637 Moreover, at certain viral doses, coadministration of the NO inhibitor during the booster resulted in IL-12-mediated enhancement of the specific CD8(+) T-cell response.

1911 10866318 Immunizing mice with dendritic cells transduced with an adenovirus expressing the human melanoma antigen glycoprotein 100 (DCAdhgp100) as a cancer vaccine, we demonstrated complete protective immunity and a potent CTL response against melanomas expressing murine glycoprotein 100 in a CD4+ cell-dependent manner.
1912 10866318 Surprisingly, however, effective tumor rejection was not the result of cooperation between CD4+ and CD8+ T cells.
1913 10866318 Protective immunity was completely lost when CD4+ cells were depleted immediately before tumor challenge, whereas it was unaffected by removal of CD8+ cells, establishing a principal role for CD4+ cells in the effector phase of tumor rejection.
1914 10866318 Neither protective immunity nor CTL generation in this model required interleukin 12, in spite of high levels of IFN-gamma secretion by tumor-reactive T cells.
1915 10866318 Most notably, the DCAdhgp100 vaccine could elicit protective antitumor CD4+ cells in the absence of CD40 ligand, although it does not bypass the need for CD40-mediated signals to generate melanoma-reactive CTLs.
1916 10866318 Thus, in contrast to the current thinking that the optimal cancer vaccine should include determinants for both CD4+ and CD8+ cells, the potency of the DCAdhgp100 vaccine appears to be a result of its ability to directly prime autoreactive CD4+ cells through a process that does not require interleukin 12 and CD40 signals.

1933 10878054 Of the 18 protein bands analyzed, 8 were found to be significantly different (P<0.05) between the two groups. p93, p34, p31, and p28 occurred with increased frequency in vaccinated dogs, while p58, p37, p35, and p30 occurred more frequently in naturally infected dogs.

1944 10900489 Naturally acquired versus vaccine-induced immunity to malaria: a dual role for TGF-beta and IL-12?
1945 10903750 Abs, CD8+ T cells, CD4+ T cells, cytokines (including IFN-gamma and IL-12), and NO have all been implicated as critical effectors.
1946 10903750 Data nevertheless suggest that a pre-erythrocytic-stage vaccine should be designed to induce CD8+ T cell- and IFN-gamma-mediated immune responses and that IFN-gamma responses may represent an in vitro correlate of pre-erythrocytic-stage protective immunity.
1947 10917199 In two phase I studies, we have immunized advanced melanoma patients with either interleukin-7 (IL-7) gene-transfected or IL-12 gene-transfected, autologous, irradiated melanoma cells.
1948 10918477 Ad infection (MOI 200) of BMDC induced significant increases in IL 12 p40 protein in culture supernatants (6 x that of uninfected BMDC and similar to that observed with addition of LPS and CD40 crosslinking antibody).

1964 10925293 In vivo depletion of CD8+ lymphocytes at the time of challenge completely ablated protective immunity in the T. gondii-primed/vaccinia-boosted animals, while neutralization of IFN-gamma or IL-12 caused a partial but significant reduction in resistance.
1965 10930678 Mice immunized with a whole homogenate (WH) of T. cruzi antigens co-administered with CpG ODN presented high titers of T. cruzi antibodies (IgG2a isotype), strong delayed type hypersensitivity and a Th1-dominated (IFN-gamma and IL-12) cytokine profile.
1966 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.
1967 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.
1968 10944482 Conversely, IL-12 and IL-10 mRNAs were elevated in VA deficiency and were induced by PIC and suppressed by RA.
1969 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.
1970 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.

2144 11220980 The importance of gamma-interferon, tumor necrosis factor alpha, interleukin 12 and other mediators in ensuring the differentiation of (CD4(+) T-cells into Th1-helpers and cytotoxic T-lymphocytes in animals infected with L. monocytogenes is described in detail.
2145 11228373 Interleukin-12 (IL-12) may be a beneficial adjuvant for augmenting vaccine efficacy against encapsulated bacteria such as Streptococcus pneumoniae and Neisseria meningitidis since it can stimulate production of interferon-gamma (IFN-gamma) and secretion of antibody isotypes that are efficient at mediating complement fixation and opsonophagocytosis.
2146 11228373 Although treatment with vaccine and IL-12 increased levels of IFN-gamma mRNA, IL-12-mediated enhancement of antibody responses still occurred in IFN-gamma(-/-) mice.

2149 11228533 The expression of CD70 and CD80 by gene-modified tumor cells induces an antitumor response depending on the MHC status.
2150 11228533 The expression of costimulatory molecules such as CD70 or CD80 by gene-modified tumor cells has been shown to enhance the antitumor immune response based mainly on T lymphocytes.
2151 11228533 To investigate if coexpression of CD70 and CD80 costimulatory molecules induces comparable antitumor responses in low and high MHC-expressing tumor cells, we used two low immunogenic murine tumor models, the B16.F10 melanoma and the TS/A mammary adenocarcinoma cell lines expressing, respectively, low and high levels of MHC class I molecules.
2152 11228533 Transfection of both CD70 and CD80 genes resulted in an increased capacity of gene-modified tumor cells to costimulate in vitro the proliferation and cytokine production of optimally activated lymphoid cells.
2153 11228533 Coexpression of CD70 and CD80 by the two tumor cell lines, TS/A and B16.F10, resulted in both cases in partial regression of subcutaneous tumors.
2154 11228533 Immunochemical analysis and studies in nude mice showed that, even in the B16.F10 model, T cells had a significant role in the antitumor response induced by combining CD70 and CD80.
2155 11228533 However, rejection of the CD70/CD80-transfected tumor cells appeared more effective in the MHC class I high TS/A model, leading to a protection against parental tumor cells.
2156 11228533 In the two models tested, the injections of irradiated IL-12 and CD70/CD80 gene-modified cells generated an antitumor response to established tumors leading to the slowing down of the tumor growth rate.
2157 11228537 Antitumor effects of the combination therapy with TNF-alpha gene-modified tumor cells and interleukin 12 in a melanoma model in mice.
2158 11228537 FACS analysis of parental B78 melanoma cells and its B78/TNF genetically modified variant showed that a proportion of cells of both cell lines expressed 87-1 (CD80) costimulatory molecule and that the expression of this molecule was increased during incubation with IFN-gamma.
2159 11228537 Moreover, IFN-gamma markedly augmented expression of major histocompatibility class (MHC) class I and II molecules on B78/TNF cells that were primarily MHC class I and II negative with no substantial effect on MHC-negative parental B78 melanoma.
2160 11228537 IFN-gamma also synergized in cytostatic/cytotoxic effects with TNF-alpha against B78 melanoma in vitro.
2161 11228537 The results suggest that, when used therapeutically, IL-12 and a vaccine containing TNF-alpha gene-transduced tumor cells may reciprocally augment their overall antitumor effectiveness by facilitating development of systemic antitumor immunity and by stimulating local effector mechanisms of the tumor destruction.

2167 11243685 The increased resistance that develops after primary infection/ vaccination requires T-cells cytokines such as IFNgamma TNFalpha and IL12 in addition to opsonising antibody.
2168 11251388 Furthermore, by coinjection of plasmids encoding cytokines GM-CSF and IL-12, respectively, nearly all of the mice are protected.

2172 11264339 Exposure to live dengue virus led to maturation and activation of both the infected and surrounding, uninfected DCs and stimulated production of tumor necrosis factor alpha (TNF-alpha) and alpha interferon (IFN-alpha).
2173 11264339 Activation of the dengue virus-infected DCs was blunted compared to the surrounding, uninfected DCs, and dengue virus infection induced low-level release of interleukin-12 p70 (IL-12 p70), a key cytokine in the development of cell-mediated immunity (CMI).
2174 11264339 Upon the addition of IFN-gamma, there was enhanced activation of dengue virus-infected DCs and enhanced dengue virus-induced IL-12 p70 release.
2175 11264339 Exposure to live dengue virus led to maturation and activation of both the infected and surrounding, uninfected DCs and stimulated production of tumor necrosis factor alpha (TNF-alpha) and alpha interferon (IFN-alpha).

2178 11269323 Furthermore, these levels were increased by the coinoculation of cytokine (IFN-gamma, IL-4, GM-CSF, or IL-12) expression plasmid.
2179 11269323 In respect to the SERA-specific Ig subclasses, coinoculation of IFN-gamma, GM-CSF, or IL-12 expression plasmid increased the levels of SERA-specific IgG2a, and these were much higher than that in mice immunized with SERA expression plasmid alone.
2180 11269323 Furthermore, these levels were increased by the coinoculation of cytokine (IFN-gamma, IL-4, GM-CSF, or IL-12) expression plasmid.

2184 11292748 These studies suggest that CD40L could be exploited to improve vaccines against intracellular pathogens, especially those organisms that reside within cells expressing CD40 on their surface.
2185 11300480 Inhibition of mammary carcinogenesis by systemic interleukin 12 or p185neu DNA vaccination in Her-2/neu transgenic BALB/c mice.
2186 11300483 Activation of these T cells was indicated by increased secretion of proinflammatory cytokines IFN-gamma, interleukin (IL)-12 and granulocyte/macrophage-colony stimulating factor, as well as specific tumor rejection and growth suppression in vaccinated CEA-transgenic mice after a lethal challenge with murine MC38 colon carcinoma cells.
2187 11300483 These tumor cells were double transfected with CEA and the human epithelial cell adhesion molecule (Ep-CAM)/KSA and consequently served as a docking site for a recombinant antibody-IL2 fusion protein (KS1/4-IL2) recognizing KSA.
2188 11300483 Importantly, the efficacy of the tumor-protective immune response was markedly increased by boosts with this antibody-IL2 fusion protein, resulting in more effective tumor rejection coupled with increased expression of costimulatory molecules B7.2/B7.2 and intercellular adhesion molecule 1 (ICAM-1) on dendritic cells and intensified release of proinflammatory cytokines IFN-gamma, IL-12, and granulocyte/macrophage-colony stimulating factor from T cells of successfully vaccinated CEA-transgenic C57BL/6J mice.
2189 11300483 Increased T-cell activation mediated by boosts with KS1/4-IL2 fusion protein after tumor cell challenge was further indicated by expanded expression of T-cell activation markers CD25, CD28, CD69, and LFA-1.
2190 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.
2191 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.
2192 11300489 Immunization of HLA-A2+ melanoma patients with MAGE-3 or MelanA peptide-pulsed autologous peripheral blood mononuclear cells plus recombinant human interleukin 12.
2193 11300489 A Phase I clinical trial was thus performed in patients with metastatic melanoma using immunization with autologous PBMCs pulsed with a MAGE-3 or a MelanA peptide, coadministered with various doses of recombinant human (rh)IL-12.
2194 11300489 Immunization of HLA-A2+ melanoma patients with MAGE-3 or MelanA peptide-pulsed autologous peripheral blood mononuclear cells plus recombinant human interleukin 12.

2196 11310844 Although all strains stimulated secretion of TNF-alpha and IL-12 strongly, PhoPc induced significantly less IL-10 than the other three strains and as much as 10 times less IL-10 than heat-killed PhoPc, suggesting that this mutant suppressed the secretion of IL-10 by the DC.

2198 11313806 In vivo depletion studies demonstrated both CD4+ and CD8+ T cells were required.
2199 11313808 Antitumor activity was also enhanced by local expression of IL-12 from dvIL12-tk/tsK.
2200 11325600 Influenza A virus infection results in the production of chemotactic (RANTES, MIP-1 alpha, MCP-1, MCP-3, and IP-10), pro-inflammatory (IL-1 beta, IL-6, IL-18, and TNF-alpha), and antiviral (IFN-alpha/beta) cytokines.
2201 11325600 Cytokine gene expression is associated with the activation of NF-kappa B, AP-1, STAT and IRF signal transducing molecules in influenza A virus-infected cells.
2202 11325600 IFN-alpha/beta also prolongs T cell survival, upregulates IL-12 and IL-18 receptor gene expression and together with IL-18 stimulates NK and T cell IFN-gamma production and the development of Th1-type immune response.
2203 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).
2204 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.
2205 11349047 The majority of beta-chemokine-producing CD8(+) T cells also produced IFN-gamma following HBa stimulation, as determined by triple-color intracellular staining.
2206 11349047 A significant number of CD8(+) T cells contained stored MIP-1beta that was released after HBa stimulation.
2207 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.
2208 11359856 IFN-gamma-inducible protein-10 is essential for the generation of a protective tumor-specific CD8 T cell response induced by single-chain IL-12 gene therapy.
2209 11359856 Here, we demonstrate that the induction of tumor-protective immunity by IL-12 in a murine neuroblastoma model depends entirely on the CXC chemokine IFN-gamma-inducible protein 10 (IP-10).
2210 11359856 This was established by in vivo depletion of IP-10 with mAbs in mice vaccinated against NXS2 neuroblastoma by gene therapy with a linearized, single-chain (sc) version of the heterodimeric cytokine IL-12 (scIL-12).

2226 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.
2227 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.
2228 11390494 Finally, using IFN-gamma gene-disrupted mice, we showed that the suppressive activity of the IL-12 plasmid was dependent upon endogenous production of IFN-gamma.
2229 11398102 MV specifically ablates IL-12 production by monocyte/macrophages in vitro through binding to CD46, a complement regulatory protein that is an MV receptor.
2230 11401973 Both the parent and lpxA strains induced production of tumor necrosis factor alpha (TNF-alpha), interleukin-1alpha (IL-1alpha), and IL-6 in DCs, although the parent was the more potent stimulus.
2231 11401973 Compared to intact bacteria, purified LPS was a very poor inducer of IL-1alpha, IL-6, and TNF-alpha production and induced no detectable IL-12.
2232 11405535 Recent insights have come from: understanding of the relationship between Mycobacterium tuberculosis and macrophages; the multiple T cell types that recognise mycobacterial peptides, lipids and glycolipids; the critical role of interferon-gamma (IFNgamma) and interleukin-12 (IL-12) in human mycobacterial infection revealed by genetically defective children; quantitation of the presence and importance of Th2 lymphocyte activation in human tuberculosis; the role of local conversion of inactive cortisone to active cortisol in the lesions; the recognition that some effective prophylactic vaccines also work as immumotherapeutics whereas others do not.

2260 11431420 The ability of cytokines to steer CD4(+) T(h) cell responses toward a T(h)1 or T(h)2 phenotype and enhance the magnitude of both CD8(+) cytotoxic T lymphocytes (CTL) and antibody responses has clearly been demonstrated by our lab and others, but the influence of cytokines on protective immune responses is much less clear.
2261 11431420 Here we show an essential role for CD4(+) T(h)1 helper cell induction and IFN-gamma production in protection from viral challenge with a recombinant vaccinia virus expressing HIV-1MN viral envelope glycoprotein gp160.
2262 11431420 Complete protection from viral challenge is achieved only when the triple combination of exogenous cytokines granulocyte macrophage colony stimulating factor (GM-CSF), IL-12 and tumor necrosis factor (TNF)-alpha are co-administered with the peptide vaccine.
2263 11431420 In vivo depletion of CD4(+) cells or immunization of IFN-gamma-deficient mice abrogates protection.

2277 11431420 In vivo depletion of CD4(+) cells or immunization of IFN-gamma-deficient mice abrogates protection.
2278 11431420 GM-CSF, IL-12 and TNF-alpha also synergize for the enhanced induction of CTL; however, adoptive transfer of a CD8(+) CTL line afforded only partial protection in this viral challenge model.
2279 11431420 We further demonstrate synergy between IL-12 and the proinflammatory cytokine TNF-alpha in driving IFN-gamma production.
2280 11431420 Thus, a combination of IL-12 and TNF-alpha is essential for the optimal development of T(h)1 responses and help for CTL induction in BALB/c mice, and is complemented by a third cytokine, GM-CSF, which enhances antigen presentation.

2285 11438430 In this study, we tested whether the co-administration of IL-12 expression plasmid which compose p35 and p40 subunits and soluble leishmanial antigen (SLA) will skew the susceptible BALB/c mice to Th1 response and protect from leishmaniasis.
2286 11438430 In contrast, the administration of empty plasmid plus SLA or IL-12 plasmid alone failed to protect the disease and shape the Th1 response.
2287 11438430 In this study, we tested whether the co-administration of IL-12 expression plasmid which compose p35 and p40 subunits and soluble leishmanial antigen (SLA) will skew the susceptible BALB/c mice to Th1 response and protect from leishmaniasis.
2288 11438430 In contrast, the administration of empty plasmid plus SLA or IL-12 plasmid alone failed to protect the disease and shape the Th1 response.
2289 11448172 Mice lacking the IFNAR1 chain of the type I IFN receptor (IFNAR K/O mice) were immunized with a plasmid encoding glycoprotein C of pseudorabies virus (PRV-gC).
2290 11448172 In contrast, IFNAR K/O mice showed a significantly lower IgG2a:IgG1 Ab ratio and IFN-gamma production.
2291 11448172 In addition, the percentage of CD8(+) and B lymph-node cells expressing CD69 after PRV-gC DNA vaccination was lower in IFNAR K/O than in WT mice.
2292 11448172 Codelivery of plasmids encoding IL-12 and IL-18 along with the plasmid encoding PRV-gC restored Th1 responses in IFNAR K/O mice.

2299 11500412 Within 6 h both 1-day- and 1-week-old mice expressed interleukin-12 p40 mRNA following either B. abortus or B. abortus-OVA administration.
2300 11500412 The absence of the early IFN-gamma response in 1-day-old mice may explain their inability to generate a Th1 memory response.

2317 11509946 To provide a means for comparing strategies for cytokine gene therapy against intracranial (i.c.) tumors, we generated rat gliosarcoma 9L cells transfected with interleukin-4 (9L-IL4), interleukin-12 (9L-IL12), granulocyte-macrophage colony-stimulating factor (9L-GMCSF) or interferon-alpha (9L-IFNalpha).
2318 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.
2319 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.
2320 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.
2321 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.

2333 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.
2334 11522639 High levels of IL-12 and IFN-gamma could be detected in the supernatants, indicating a T-helper type 1-type immune response.
2335 11527700 T Lymphocytes infiltrating various tumour types express the MHC class II ligand lymphocyte activation gene-3 (LAG-3): role of LAG-3/MHC class II interactions in cell-cell contacts.
2336 11527700 The product of the Lymphocyte Activation Gene-3 (LAG-3, CD223) is a high affinity MHC class II ligand expressed by activated CD4(+) and CD8(+) T cells, which can associate with the T cell receptor (TCR) and downregulate TCR signalling in vitro.
2337 11527700 We have also reported that a soluble mLAG-3Ig fusion protein works as a vaccine adjuvant in vivo in mice, enhancing Th1 and CD8 T cell responses.
2338 11527700 Here, we report that LAG-3 expression was found, using fluorescent activated cell sorting (FACS) analysis, on 11-48% of human tumour-infiltrating lymphocytes (TILs) isolated from eight freshly dissociated renal cell carcinomas (RCCs), and was restricted mostly to CD8(+) cells.
2339 11527700 Since not only antigen presenting cells (APCs), but also TILs themselves strongly express major histocompatibility complex (MHC) class II, we firstly investigated whether LAG-3/MHC class II T-T cell contacts might influence tumour cell recognition.
2340 11527700 In contrast, MHC class II engagement by LAG-3Ig was found to enhance the capacity of immature dendritic cells to stimulate naive T cell proliferation and IL-12-dependent IFN-gamma production by T cells in vitro.
2341 11527700 These results therefore provide support for a role for TIL-expressed LAG-3 in the engagement of class II molecules on APCs, thereby contributing to APC activation and Th1/Tc1 commitment, without downregulating cytotoxicity.
2342 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.
2343 11535343 The majority of donors in both groups did not exhibit an increase in measles specific IL-4 or IL-10 mRNA after vaccination.

2354 11562066 Specifically, we examined the effect of mycobacterial antigens, Bacillus Calmette-Guerin (BCG) vaccine and Mycobacterium vaccae, on antigen-induced bronchoconstriction, airway hyperresponsiveness to methacholine, bronchoalveolar lavage eosinophilia, and plasma IL-4 and IL-12 levels in ovalbumin (OVA)-sensitized and challenged Balb/c mice.
2355 11567752 Viral clearance from the vaginal mucosa was more rapid in mice infected with a US3-deficient mutant L1BR1 as compared with a wild-type 186 or YY2 (US2-deficient mutant) infection, although there was no significant difference among them in initial growth in the early stage of infection.
2356 11567752 Moreover, the levels of IL-12 and IFN-gamma increased in L1BR1-infected mice over levels in 186-infected mice.
2357 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.
2358 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.
2359 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).
2360 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.
2361 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.
2362 11591784 Fourth, activation of CTLs was augmented, as indicated by up-regulation of activity markers LFA-1, CD25, CD28, and CD69.
2363 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.
2364 11599738 In re-analyses of sera for total immunoglobulins in ELISAs with recombinant antigens, reactions were most frequently recorded when outer-surface protein (Osp) F, protein (p)35, p37, p39 and p-41G (a flagellin component) were tested separately.
2365 11599738 Sera from vaccinated dogs contained antibodies to OspA, OspB, p22, p37 and p41-G.
2366 11599738 Therefore, serological reactions to OspF, p35 and p39 were the most important indicators of natural exposure to B. burgdorferi.
2367 11606395 Lymphocytes from mice treated with BNL lysate-pulsed DCs and IL-12 showed stronger cytolytic activity and produced higher amounts of IFN-gamma than those from mice treated with BNL lysate-pulsed DCs alone.
2368 11606395 In vivo lymphocyte depletion experiments demonstrated that this combination was dependent on both CD8+ and CD4+ T cells, but not natural killer cells.
2369 11641967 Recently, mutations in the interferon-gamma receptor ligand-binding chain (IFN gamma R1), interferon-gamma receptor signaling chain (IFN gamma R2), Signal Transducer and Activator of Transcription-1 (STAT-1), interleukin-12 p40 subunit (IL-12 p40), and interleukin-12 receptor beta 1 chain (IL-12R beta 1) genes have been identified in a number of patients with severe BCG or NTM infection.
2370 11642602 In contrast, exposure to serum-free medium and interferon-gamma (IFN-gamma) rapidly influences CD83+ DCs to secrete high levels of IL-12, IL-6, and MIP-1beta, and promotes Dcl differentiation.
2371 11642602 In contrast, CD83+ DCs matured in serum-free medium in the absence of IFN-gamma, or in the presence of calcium signaling agents, prostaglandin-E2, or IFN-alpha, produce no IL-12, scant IL-6, and prodigious IL-8, MDC, and TARC, and promote Dc2 differentiation.
2372 11642602 In contrast, exposure to serum-free medium and interferon-gamma (IFN-gamma) rapidly influences CD83+ DCs to secrete high levels of IL-12, IL-6, and MIP-1beta, and promotes Dcl differentiation.

2378 11673557 We found that combinations of IL-1alpha plus IL-18, IL-1alpha plus IL-12, and IL-1alpha plus IL-12 plus GM-CSF each induced optimal splenocyte anti-HIV CTL responses in immunized mice (range 60-71% peptide-specific (51)Cr release).
2379 11673557 Nasal immunization with HIV immunogen and IL-1alpha, IL-12, and GM-CSF also induced Ag-specific IFN-gamma-secreting cells in the draining cervical lymph node and the lung.
2380 11673557 The use of IL-1alpha, IL-12, and GM-CSF as nasal adjuvants was associated with an increased expression of MHC class II and B7.1 on nonlymphocytes within the nasal-associated lymphoid tissue/nasal mucosa.
2381 11673557 Thus, IL-1alpha, IL-12, IL-18, and GM-CSF are critical cytokines for the induction of systemic and mucosal CTL after nasal immunization.
2382 11673557 We found that combinations of IL-1alpha plus IL-18, IL-1alpha plus IL-12, and IL-1alpha plus IL-12 plus GM-CSF each induced optimal splenocyte anti-HIV CTL responses in immunized mice (range 60-71% peptide-specific (51)Cr release).

2390 11675375 Here, in the course of trying to understand the mechanism for synergy between IL-12 and TNF-alpha in up-regulating IFN-gamma production, we find that when the stimulus through the TCR is too weak to induce cell proliferation, which would be needed for selection, IL-12 and TNF-alpha synergize to up-regulate not only IFN-gamma, but also the IL-12Rbeta2 chain, which triggers IFN-gamma production.
2391 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.

2393 11696586 Combined allogeneic tumor cell vaccination and systemic interleukin 12 prevents mammary carcinogenesis in HER-2/neu transgenic mice.
2394 11696586 A significant improvement in tumor prevention was sought by administering allogeneic mammary carcinoma cells expressing HER-2/neu combined with systemic IL-12.
2395 11696586 The mammary glands of mice receiving the combined treatment displayed a markedly reduced epithelial cell proliferation, angiogenesis, and HER-2/neu expression, while the few hyperplastic foci were heavily infiltrated by granulocytes, macrophages, and CD8(+) lymphocytes.
2396 11696586 Specific anti-HER-2/neu antibodies were produced and a nonpolarized activation of CD4(+) and CD8(+) cells secreting IL-4 and interferon (IFN)-gamma were evident.
2397 11696586 A central role for IFN-gamma in the preventive effect was proven by the lack of efficacy of vaccination in IFN-gamma gene knockout HER-2/neu transgenic Balb/c mice.
2398 11696586 A possible requirement for IFN-gamma is related to its effect on antibody production, in particular on IgG2a and IgG2b subclasses, that were not induced in IFN-gamma knockout HER-2/neu mice.
2399 11696586 In conclusion, our data show that an allogeneic HER-2/neu-expressing cell vaccine combined with IL-12 systemic treatment can prevent the onset of genetically determined tumors.

2505 11857039 Adenovirus-mediated CD40 ligand gene-engineered dendritic cells elicit enhanced CD8(+) cytotoxic T-cell activation and antitumor immunity.
2506 11857039 CD40L, the ligand for CD40 on dendritic cells (DCs), plays an important role in their activation and is essential for induction of antigen-specific T-cell responses.
2507 11857039 Our data show that transfection of DCs with recombinant adenovirus AdV-CD40L resulted in activation of DCs with up-regulated expression of proinflammatory cytokines (IL-1beta and IL-12), chemokines (RANTES, IP-10, and MIP-1alpha), and immunologically important cell surface molecules (CD54, CD80, and CD86).

2537 11902331 Downmodulation of CD18 and CD86 on macrophages and VLA-4 on lymphocytes in experimental tuberculosis.
2538 11902331 In this paper, we show that virulent M. tuberculosis H37Rv downmodulates the ex vivo expression of CD18 and CD86 on peritoneal macrophages and VLA-4 on lymphocytes but does not disturb the in vitro production of interleukin (IL)-12 and interferon (IFN)-gamma after intraperitoneal infection.
2539 11902331 The interplay among IL-12, IFN-gamma and IL-10 in vivo and the downmodulation of cell-surface receptors during the infection at the inflammatory site may contribute to the explanation of the maintenance of infection.

2680 12111121 Surprisingly, both perforin and FasL played unique roles during the effector phase of immunity to Panc02.MUC1, while lymphotoxin-alpha, but not TNFR-1, was required for immunity against Panc02.MUC1 tumors.
2681 12111122 We showed that bone marrow-derived DC pulsed with Id-CD40L upregulated the expression of CD40, CD80, CD86, and major histocompatibility complex (MHC) class II molecules with the increased production of interleukin-12 (IL-12).
2682 12117936 Oral immunization of mice with a Salmonella vaccine expressing colonization factor antigen I (CFA/I) from enterotoxigenic Escherichia coli results in the rapid onset of interleukin-4 (IL-4) and IL-5 production, which explains the observed elevations in mucosal immunoglobulin A (IgA) and serum IgG1 antibodies.
2683 12117936 Upon measurement of proinflammatory cytokines, minimal to no tumor necrosis factor alpha (TNF-alpha), IL-1alpha, IL-1beta, or IL-6 was produced by Salmonella-CFA/I-infected RAW 264.7 or peritoneal macrophages, but production was greatly induced in Salmonella vector-infected macrophages.
2684 12117936 Only minute levels of IL-12 p70 were induced by Salmonella vector-infected macrophages, and none was induced by Salmonella-CFA/I-infected macrophages.
2685 12117936 The absence of IL-12 was not due to overt increases in production of either IL-12 p40 or IL-10.

2714 12134231 Both native PT (nPT) and genetically detoxified PT (dPT) efficiently promoted expression on DCs of CD80, CD86, human leukocyte antigen-DR, and CD83 markers, alloreactive antigen presentation, and cytokine production, primarily interferon (IFN)-gamma.
2715 12134231 Although they did not affect interleukin (IL)-10 production by lipopolysaccharide (LPS)-stimulated DCs, both nPT and dPT strongly synergized with LPS for IL-12 production.
2716 12134231 PTs plus LPS-stimulated DCs secreted soluble factors fostering IFN-gamma but not IL-4 and IL-5 production by naive T cells.
2717 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.
2718 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.
2719 12149420 Stimulation of CD4(+) T cells induced similar levels of IL-2-and IL-4-like activity and interferon-gamma.
2720 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.
2721 12149423 CD1a(+) DC derived from precursors, expanded in fms-like tyrosine kinase-3 ligand (Flt3-L), stem-cell factor (SCF), interleukin (IL)-3, and IL-6, were less potent antigen-presenting cells (APC) compared to CD1a(+) DC derived from precursors expanded in Flt3-L, trombopoietine (TPO), and SCF.
2722 12149423 Furthermore, the latter produced high levels of IL-12 and low levels of IL-10, a cytokine profile favorable for the priming cytotoxic T cells.
2723 12149423 In contrast, a mean increase of total cell number of 453-fold was obtained with Flt3-L, SCF, IL-3, and IL-6, and this increase was only 38-fold with Flt3-L, TPO, and SCF.
2724 12163272 IL-6, IL-8 and IL-12 were consistently detected in challenged animals that had been vaccinated.
2725 12163272 Other cytokines--IL-1, IL-2, TNF, TGF and interferons--were not detected.
2726 12163272 Although the IL-6 and IL-8 did not relate to protection, IL-12 production was highest in the protected vaccinated pigs.
2727 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.

2733 12193724 Clearance of facultative intracellular pathogens such as Salmonella requires IFN-gamma from CD4 T cells.
2734 12193724 Even transient attenuation of Ag presentation early during infection specifically abrogates the IFN-gamma component of the resulting CD4 T cell response.
2735 12193724 Furthermore, macrophages from IL-4-null mice secrete high levels of both IL-12 and IL-18 in response to stimulation in vivo even with dead bacteria, but this does not lead to induction of IFN-gamma-secreting T cells in response to immunization with dead S. typhimurium.
2736 12193724 Early IL-4 is contributed by triggering of CD4 NK T cells by dead, but not live, bacteria.
2737 12193724 Thus, Ag presentation-related IL-12-independent events and IL-4-sensitive IL-12-dependent events play crucial complementary roles in the generation of the IFN-gamma-committed CD4 T cell component of the immune response in Salmonella infection.

2790 12223511 When mice were immunized with OVA/B. pertussis, we found that the IgG2a/IgG1 ratio and OVA-specific T cell response were lower in aged mice and elicited IFN-gamma and IL-5.
2791 12223511 In vitro CpG-DNA stimulated antigen-presenting cells to display IL-12 and up-regulate the expression of major histocompatibility complex class II and B7-2 on B cells as efficiently in aged as in young mice, but the up-regulation of B7-1 was stronger in aged mice.

2813 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.
2814 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).
2815 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.

2825 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.
2826 12239302 We examined the formation of mimovirus by DNA retardation assay, DNase I protection assay, and transmission electron microscopy and demonstrated that mimovirus could efficiently transfer the plasmid encoding IL-12 into mammalian cells such as P815 cells in vitro.
2827 12349944 P3CSK4 activates the expression of tumor suppressor protein p53 (p53), c-rel, inhibitor of nuclear factor kappa B (NFkappaB) alpha (IkappaB alpha), type 2 (inducible) nitric oxide (NO) synthase (iNOS), CD40-LR, intercellular adhesion molecule-1 (ICAM-1) and interleukin 1/6/15 (IL-1/6/15).
2828 12349944 We detected no activation of heat shock protein (HSP) 27, 60, 84 and 86, osmotic stress protein 94 (Osp 94), IL-12, extracellular signal-regulated protein kinase 1 (ERK1), p38 mitogen activated protein (MAP)-kinase (p38), c-Jun NH2-terminal kinase (JNK), signal transducer and activator of transcription 1 (STAT1), CD14 and caspase genes.
2829 12349944 Furthermore, we monitored inhibition of STAT6, Janus kinase 3 (Jak3) and cyclin D1/D3 gene transcription after stimulating bone marrow-derived macrophages (BMDM) with lipopeptide.
2830 12381575 In the initial testing of this system, we found that mRNA expression of certain cytokines (interleukin [IL]-1beta, IL-6, IL-12, IL-15, GM-CSF, iNOS, and tumor necrosis factor [TNF]-alpha) is enhanced when monocyte-derived macrophages are stimulated with peptide antigen conjugated with mannan under oxidizing conditions compared to peptide conjugated with reduced mannan.
2831 12384803 Th1-type responses which comprise cell-mediated immunity are characterised by the secretion of interferon-gamma by T cells, which is induced by antigen-presenting cell (APC)-derived IL-12.
2832 12385032 In experiments designed to get insights into the interactions between PTX and circulating immune cells, we first observed that addition of PTX to adult whole blood induced the release of IL-12 and TNF-alpha as well as maturation of myeloid dendritic cells (DC).
2833 12385032 Secondly, studies on DC generated in vitro by culturing monocytes with IL-4 and GM-CSF showed that PTX directly stimulates MHC class II and costimulatory molecules up-regulation, cytokine synthesis and NF-kappa B activation.
2834 12386826 Immunosuppressive effects of interleukin-12 coexpression in melanoma antigen gene-modified dendritic cell vaccines.
2835 12386826 In a series of experiments immunizing mice with DC cotransduced with MART-1 and IL-12, antitumor protection and antigen-specific splenocyte cytotoxicity and interferon gamma production inversely correlated with the amount of IL-12 produced by DC.

2837 12386826 In a series of experiments immunizing mice with DC cotransduced with MART-1 and IL-12, antitumor protection and antigen-specific splenocyte cytotoxicity and interferon gamma production inversely correlated with the amount of IL-12 produced by DC.
2838 12390544 Protection by SIV VLP DNA prime/protein boost following mucosal SIV challenge is markedly enhanced by IL-12/GM-CSF co-administration.
2839 12390544 Thus, groups of monkeys were administered three consecutive doses of pVecB7 a plasmid expressing VLP with or without plasmids expressing IL-12 and GM-CSF at weeks 0, 13 and 26.
2840 12390544 While all immunized monkeys showed a marked reduction of acute viral peaks, reduction of viral load set points was only achieved in groups whose prime-boost immunizations were supplemented with IL-12/GM-CSF (prime) and/or with IL-12 (boost).

2853 12390544 In summary, use of IL-12 and/or GM-CSF was shown to provide significant differences in the outcome of SIV challenge of prime/boost immunized monkeys.
2854 12391201 CD28, TNF receptor, and IL-12 are critical for CD4-independent cross-priming of therapeutic antitumor CD8+ T cells.
2855 12391201 Previously, we have shown that priming of therapeutic CD8(+) T cells in tumor vaccine-draining lymph nodes of mice vaccinated with GM-CSF secreting B16BL6 melanoma cells occurs independent of CD4 T cell help.
2856 12391201 In this study, we examined the contribution of the major costimulatory molecules, CD40 ligand (CD40L), CD80, and CD86, in the priming of CD8(+) T cells.
2857 12391201 Priming of therapeutic CD8(+) T cells by a GM-CSF-transduced tumor vaccine did not require CD40 and CD40L interactions, as therapeutic T cells could be generated from mice injected with anti-CD40L Ab and from CD40L knockout mice.
2858 12391201 However, costimulation via either CD80 or CD86 was required, as therapeutic T cells could be generated from mice injected with either anti-CD80 or anti-CD86 Ab alone, but administration of both Abs completely inhibited the priming of therapeutic T cells.
2859 12391201 Blocking experiments also identified that priming of therapeutic T cells in MHC class II-deficient mice required TNFR and IL-12 signaling, but signaling through CD40, lymphotoxin-betaR, or receptor activator of NF-kappaB was not essential.
2860 12391201 Thus, cross-priming of therapeutic CD8(+) T cells by a tumor vaccine transduced with GM-CSF requires TNFR, IL-12, and CD28 signaling.
2861 12391201 CD28, TNF receptor, and IL-12 are critical for CD4-independent cross-priming of therapeutic antitumor CD8+ T cells.

2868 12393660 Autologous and MHC class I-negative allogeneic tumor cells secreting IL-12 together cure disseminated A20 lymphoma.
2869 12393660 Here, we show that allogeneic B78H1 major histocompatibility complex (MHC) class I-negative and -positive (H-2K(b)- and D(b)-transfected) cells induced cytotoxic T lymphocytes (CTLs) and protection in BALB/c mice at comparable levels in response to a challenge with C26 (H-2(d)) colon carcinoma cells sharing the tumor-associated antigen envelope glycoprotein 70 (env-gp70) with both cell lines.
2870 12393660 Indeed, only CD4(+) T cells from IL-12-treated mice could be restimulated with anti-OX40 monoclonal antibody (mAb) in place of a fourth cellular boost.
2871 12393660 Moreover, the IL-12-based tumor vaccine induced expansion of tumor-specific interferon-gamma (IFN-gamma)-producing CD8(+) T cells.
2872 12393660 Autologous and MHC class I-negative allogeneic tumor cells secreting IL-12 together cure disseminated A20 lymphoma.

2876 12438333 Dynamics of gamma interferon, interleukin-12 (IL-12), IL-10, and transforming growth factor beta mRNA expression in primary Mycobacterium bovis BCG infection in guinea pigs measured by a real-time fluorogenic reverse transcription-PCR assay.
2877 12438333 Initially, we established a quantitative assay using a real-time reverse transcription-PCR (RT-PCR) to measure guinea pig gamma interferon (IFN-gamma), interleukin-12 (IL-12), IL-10, and transforming growth factor beta (TGF-beta) mRNA.
2878 12438333 The expression of IL-10 and TGF-beta increased slightly only in PBMCs.
2879 12438333 In this study, we quantitatively measured IL-10, IL-12, TGF-beta, and IFN-gamma mRNA in BCG-immunized guinea pigs and showed that the level of IFN-gamma mRNA expression does not necessarily reflect the magnitude of the DTH response, suggesting that there may be an intricate relationship between protective immunity, the level of IFN-gamma, and the DTH response.

2888 12438346 Intranasal vaccinations were given with recombinant interleukin-12 (IL-12)- and IL-4-neutralizing antibody (Ab) for type 1 immune bias, or recombinant IL-4 and gamma interferon-neutralizing Ab for type 2 immune bias.
2889 12450698 In order to induce effective CTL responses against most infections and tumours, DCs must prime both CD4(+) and CD8(+) antigen-specific T cells.
2890 12450698 In this study, the infection of immature mouse bone marrow-derived DCs (BMDCs) with recombinant adenovirus (rAd) vectors led to a marked upregulation of surface costimulatory molecules, IL-12 p40 production and capacity to stimulate both allogeneic and antigen-specific T cells.
2891 12450698 Furthermore, infection of immature and mature BMDCs with a rAd encoding chicken ovalbumin (OVA) led to presentation of the antigen to TCR-transgenic OVA-specific CD4(+) and CD8(+) T cells.
2892 12450698 In addition, the activation state of responding CD8(+) T cells was further amplified if they recognised antigen on rAd-transduced BMDCs in the presence of antigen-specific CD4(+) T cells.
2893 12450698 The results suggest that rAd-encoded OVA protein is secreted by BMDCs, taken up by endocytosis and presented in association with MHC class II molecules for activation of OVA-specific CD4(+) T cells.
2894 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.
2895 12483966 At 18 weeks post-immunization, the production of both IFN-gamma and IL-12 was apparently down-regulated, but that of IL-10 was up-regulated.
2896 12483966 IL-10 seemed to suppress the IFN-gamma and IL-12 productions, because their production was recovered by neutralization of IL-10 with anti-IL-10 mAb.
2897 12483966 At 18 weeks post-immunization, the production of both IFN-gamma and IL-12 was apparently down-regulated, but that of IL-10 was up-regulated.
2898 12483966 IL-10 seemed to suppress the IFN-gamma and IL-12 productions, because their production was recovered by neutralization of IL-10 with anti-IL-10 mAb.
2899 12496156 Splenic dendritic cells (DCs) obtained from mice at 48 h after Listeria monocytogenes infection exhibited up-regulation of CD80 and produced higher titers of gamma interferon (IFN-gamma) and interleukin-12 (IL-12) than did DCs obtained from uninfected mice.
2900 12496156 Infected DCs stimulated proliferation of naive CD4(+) and CD8(+) cells in vitro, suggesting that in vivo-infected DCs activate CD8(+) T cells, which are critical in acquired antilisterial resistance, as well as CD4(+) T cells.
2901 12496156 These results suggest that DC-derived IL-12, but not IFN-gamma, may play a critical role in induction of acquired antilisterial resistance.
2902 12496156 Splenic dendritic cells (DCs) obtained from mice at 48 h after Listeria monocytogenes infection exhibited up-regulation of CD80 and produced higher titers of gamma interferon (IFN-gamma) and interleukin-12 (IL-12) than did DCs obtained from uninfected mice.
2903 12496156 Infected DCs stimulated proliferation of naive CD4(+) and CD8(+) cells in vitro, suggesting that in vivo-infected DCs activate CD8(+) T cells, which are critical in acquired antilisterial resistance, as well as CD4(+) T cells.
2904 12496156 These results suggest that DC-derived IL-12, but not IFN-gamma, may play a critical role in induction of acquired antilisterial resistance.
2905 12496388 OX40 ligand-transduced tumor cell vaccine synergizes with GM-CSF and requires CD40-Apc signaling to boost the host T cell antitumor response.
2906 12496388 Efficient T cell priming by GM-CSF and CD40 ligand double-transduced C26 murine colon carcinoma is not sufficient to cure metastases in a therapeutic setting.
2907 12496388 To determine whether a cellular vaccine that interacts directly with both APC and T cells in vivo might be superior, we generated C26 carcinoma cells transduced with the T cell costimulatory molecule OX40 ligand (OX40L) either alone (C26/OX40L) or together with GM-CSF (C26/GM/OX40L), which is known to activate APC.
2908 12496388 Tumor rejection required granulocytes, CD4+, CD8+ T cells, and APC-mediated CD40-CD40 ligand cosignaling, but not IFN-gamma or IL-12 as shown using subset-depleted and knockout (KO) mice.
2909 12496388 Indeed, CD4+ T cell-depleted mice failed to mount any CTL activity against the C26 tumor, while treatment with agonistic mAb to CD40, which acts on APC, bypassed the requirement for CD4+ T cells and restored CTL activation.
2910 12502811 The CpG ODN-induced protection was associated with a rapid production of gamma interferon (IFN-gamma), interleukin-12 (IL-12), IL-18, and RANTES in the genital tract mucosa following CpG ODN treatment.
2911 12502811 The observed protection appeared to be dependent on IFN-gamma, IL-12, IL-18, and T cells, as CpG ODN pretreatment did not confer any significant protection in mice deficient in IFN-gamma, IL-12, IL-18, or T cells.
2912 12502811 The CpG ODN-induced protection was associated with a rapid production of gamma interferon (IFN-gamma), interleukin-12 (IL-12), IL-18, and RANTES in the genital tract mucosa following CpG ODN treatment.
2913 12502811 The observed protection appeared to be dependent on IFN-gamma, IL-12, IL-18, and T cells, as CpG ODN pretreatment did not confer any significant protection in mice deficient in IFN-gamma, IL-12, IL-18, or T cells.
2914 12505710 After freeze-thawing, DCs produced lower levels of IL-12 p40 and IL-12 p70 on maturation compared to fresh DCs with little change in concentration over 72 h.
2915 12513792 The phenotype of DC was detected by FCM with CD1a, CD40, CD80, CD86, HLA-A, B, C and HLA-DR monoclonal antibodies.
2916 12513792 The level of IL-12 and IFN-gamma in supernatant of DC culture was measured by ELISA.
2917 12513792 A high expression of phenotypes was found in HL-60-DC and THP-1-DC stimulated by GM-CSF + IL-4 + TNF-gamma and K562-DC with GM-CSF + IL-4 + IL-12.
2918 12513927 Animals received four injections of recombinant porcine IL-1 and IL-6, IL-12 alone, or CT alone within 1 week of intramuscular administration of a vaccine strain of PRRSV, Ingelvac MLV.
2919 12513927 Second, animals that received CT adjuvant displayed a more robust antibody response to GP5, the major envelope glycoprotein.
2920 12513927 It acts in part through the production of IL-1 in macrophages, but its effect was not replaced by combination treatment with IL-1 and IL-6.
2921 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.
2922 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.
2923 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.
2924 12519306 Blocking antibodies to B7.1 and B7.2 or IL-12 significantly reduced the secretion of IFN-gamma and reductions were also seen in the expression of CD25 and CD71 by CD4+ cells.
2925 12529500 The most improved evolved IL-12 (EvIL-12) derived from seven mammalian genes encoding both the p35 and p40 subunits of IL-12 showed a 128-fold improvement in human T cell proliferation compared with native hIL-12 during the initial screening of supernatants from transected cells.
2926 12531355 We observed that HIV-1 envelope glycoprotein immunization of peptide primed mice induces a cross-reactive cellular response, as detected by cytokine secretion, which lends to IFN-gamma production upon splenocyte stimulation and CTL activity against recombinant vaccinia virus infected cells after in vitro stimulation.
2927 12531355 DNA immunization with mimotope, inclusion of a T-cell epitope from the HIV-1 envelope protein in the expression cassette and co-administration with IL-12 or GM-CSF encoding plasmids activate a cellular response to the HIV-1 envelope protein.
2928 12534946 In addition, CpG DNA was found to activate epidermal Langerhans cells and stimulate the production of TNF-alpha and IL-12 cytokines by epidermal cells, explaining its strong adjuvant activity following epidermal powder immunization.
2929 12540559 We here report that BALB/c interleukin-4 knockout (IL-4(-/-)) mice are weakly overcolonized compared to the wt strain but that the IL-12(-/-) knockout results in a strong overcolonization (500%).

2944 12540573 Vaccine-induced reduction of Helicobacter pylori colonization in mice is interleukin-12 dependent but gamma interferon and inducible nitric oxide synthase independent.
2945 12540573 Elevated levels of mRNA for interleukin-12p40 (IL-12p40), gamma interferon (IFN-gamma), tumor necrosis factor alpha, and inducible nitric oxide synthase (iNOS) were associated with protection in immunized-challenged (I/C) mice, but Th2 cytokine (IL-4, IL-5, IL-10, and IL-13) and chemokine (KC, MIP-2, and MCP-1) expression was not associated with protection.
2946 12540573 Despite the association of IFN-gamma and iNOS message with protection, I/C mice genetically lacking either of these products were able to reduce the bacterial load as well as the wild-type I/C controls.

3022 12590704 4-1BB ligand stimulation enhances myeloid dendritic cell maturation from human umbilical cord blood CD34+ progenitor cells.
3023 12590704 We investigated whether 4-1BB ligand (4-1BBL), a member of the tumor necrosis factor (TNF) family, is involved in the maturation process to mature myeloid DCs during in vitro DC differentiation from immature DCs derived from human umbilical cord blood (CB) CD34(+) progenitor cells.
3024 12590704 Enhanced levels of CD11c as well as immunostimulatory molecules such as CD86, MHC class II, and 4-1BBL were induced in response to 4-1BBL stimulation.
3025 12590704 Stimulation of 4-1BBL on DCs with 4-1BB-Fc or with 4-1BB-transfected Jurkat cells resulted in acquisition of capacity for the immature DCs to produce interleukin-12 (IL-12).
3026 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.
3027 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.
3028 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.
3029 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.
3030 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.
3031 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.

3034 12603608 A significant correlation (P < 0.025) between immunogenicity and the ratio of tumour-specific interferon-gamma : interleukin-4 (IL-4) secretion by TVDLN T cells was identified.
3035 12603608 We then documented that non-therapeutic T cells primed by the poorly immunogenic D5, recognized "tumour-rejection" antigens and that reprogramming their cytokine response, by in vitro culture with IL-12 and anti-IL-4, to a T1 profile uncovered therapeutic efficacy.
3036 12604047 We observed that IL-12 and IL-15 were effective as plasmid vaccine adjuvants.
3037 12605699 Here we report that live Leishmania promastigotes (the form that is injected by the vector) can directly induce human peripheral blood NK cells from healthy donors to IFN gamma secretion in the absence of IL-12 and professional antigen presenting cells.
3038 12615440 After the Plasmodium yoelii challenge, mice immunized with MSP1-15 plus IL-12 DNA showed a higher level of interferon gamma (IFN-gamma) production than did other groups of mice.
3039 12615440 In vivo neutralization of IFN-gamma or depletion of CD4(+) T cells completely abolished this protective immunity.
3040 12618487 In a previous study we showed that immunization with dendritic cells (DC) pulsed with idiotype (Id) fused with CD40 ligand (CD40L) could break the tolerance to Id which is expressed on B lymphoma cells and restored the responsiveness of T(h) cells, and, subsequently, induced IgG antibody response.
3041 12618487 On examining the mechanism for this isotype change, we found that IFN-gamma production by CD4(+) T cells is not the only determining factor for achieving a successful therapy.
3042 12618487 The deciding factor appears to be the abrogation of IL-4 production that was achieved by combing with IL-12 gene therapy.
3043 12639819 OM-197 upregulated the expression of HLA-DR, CD80, CD86, CD83, CD40 and CD54 at the surface of myeloid DC naturally present in blood as well as of DC generated in vitro from monocytes using IL-4 and GM-CSF.
3044 12639819 OM-197 also induced the release of IL-12 and TNF-alpha from DC.
3045 12639819 Finally, DC incubated with OM-197 after pulsing with hepatitis B surface antigen (HBs Ag) induced in vitro expansion of IFN-gamma-secreting HBs Ag-specific CD4(+) T lymphocytes from naive individuals.

3103 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).
3104 12668155 In mice cytokines IL-2, IL-12, IL-18, and GMCSF are observed to synergize with BCG for IFN-gamma production, whereas in human cytokines IL-2, IL-12, TNF-alpha, and IFN-alpha exhibit similar synergistic effects.

3109 12669245 In vitro culture of immature DC generated from adherent peripheral blood mononuclear cells (PBMC) using granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4) with OK432 at various doses (0.01 to 0.1 KE/ml) for 2 days resulted in increased cell surface expression of CD80, CD83, CD86 and ICAM-1 in a dose-dependent manner.
3110 12669245 Assay of cytokine production in OK-DC after 2 days in culture revealed that OK432 was a strong inducer of IL-12 and interferon-gamma (IFN-gamma).
3111 12683337 The single deletion of IFN-gamma or TNF alpha resulted in a severe lesion of multiple necrosis without granuloma, and cytokine mRNA level other than knocked out cytokine was normal, suggesting that IFN-gamma and TNF alpha are principally important cytokines.
3112 12683337 In knockout mice for IL-12 or IL-18, necrotic lesion was not induced after infection and the pathological change was not so significant as in IFN-gamma/TNF alpha knockout mice.
3113 12683337 By using IL-12, IL-18 knockout mice or double knockout mice, it was shown that IL-12 exhibits more important role than IL-18 in the protection.

3126 12699364 Cytokine and chemokine combinations can potentially help target antigen to the appropriate antigen presenting cell and initiate maturation of these presenting cells, attract cells expressing different chemokine receptors, steer cellular immune responses toward Th1 and CD8 CTL, and enhance systemic and mucosal IgG and secretory IgA antibodies and determine their isotype balance.
3127 12699364 For example, GM-CSF has been shown to be synergistic with IL-12 or CD40 ligand for induction of CTL and for antiviral protection, and the triple combination of GM-CSF, IL-12, and TNF alpha appears to induce the most effective protection in some mouse models.
3128 12706410 Interestingly, there was a negative correlation between binding intensity and CD83 expression in DCs, suggesting that the main receptor for binding of VLPs may be downregulated during maturation.
3129 12706410 For each cell type, the patterns of interleukin-1beta, interleukin-12, tumor necrosis factor-alpha, and interleukin-6 production were distinct from the pattern induced by lipopolysaccharide (LPS), a bacterial activator of myeloid antigen-presenting cells.
3130 12737995 Murine bone marrow macrophages treated in vitro with F. novicida LPS produced IL12 and TNF-alpha, but did not produce detectable interferon-gamma, IL10, or nitric oxide; in contrast, murine macrophages treated with F. tularensis LVS LPS produced none of these mediators.
3131 12737995 Thus, although LPS recognition may not be a major factor in engendering protection, the ability of F. novicida LPS to stimulate the production of proinflammatory cytokines including TNF-alpha likely contributes to the increased virulence for mice of F. novicida compared to F. tularensis LVS.
3132 12744881 The interleukin 4 (IL-4), interferon gamma (IFNgamma) and IL-12 (p40 subunit) cytokine mRNA expression profiles in PBMC as well as lymphocyte proliferative response and the IgG2/IgG1 ratios specific for LACK suggest that in vaccinated animals there is triggering of cellular immune responses.
3133 12769784 Neither interleukin-12 (IL-12), IL-10, nor CD8(+) T-cells participated in the regulation.
3134 12777059 Using a self-tumor antigen model, we vaccinated rats with a plasmid-based rat neu intracellular domain (ICD) DNA construct and either no adjuvant, soluble GM-CSF, or IL-12.
3135 12777059 We demonstrate that the addition of soluble GM-CSF or IL-12 to rat neu ICD DNA vaccination elicits detectable neu specific T cell immunity; specifically the generation of CTL.

3138 12778462 IL-12 is the signature IFN-gamma-inducing cytokine and, as such, is thought to be crucial for protective immunity against intracellular microorganisms.
3139 12781697 When delivered i.n., IL-12 induces less systemic IFN-gamma production and fewer pathological tissue changes, yet is efficacious, as indicated by enhanced CD3(+) T cell activation and increased production of Th1-associated immunoglobulins (i.e., serum IgG2a).
3140 12787733 Our results show that the coadministration of plasmid DNA encoding IL-12 or IL-18 along with glycoprotein B (gB) DNA improves immune induction.
3141 12791648 We found that both human and murine DCs pulsed with live fungi or transfected with fungal RNA underwent functional maturation, as revealed by the up-regulated expression of histocompatibility class II antigen and costimulatory molecules and the production of interleukin 12 (IL-12) in response to conidia or conidial RNA and of IL-4/IL-10 in response to hyphae or hyphal RNA.
3142 12794148 Both lymphotoxin-alpha and TNF are crucial for control of Toxoplasma gondii in the central nervous system.
3143 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.
3144 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.
3145 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.
3146 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.
3147 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.
3148 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.
3149 12794148 Generation and infection of bone marrow reconstitution chimeras demonstrated an exclusive role of hematogeneously produced TNF and LTalpha for survival of toxoplasmosis.
3150 12794148 These findings demonstrate the crucial role of both LTalpha and TNF for control of intracerebral toxoplasms.

3160 12798635 In all species so far studied, IgG isotype expression is controlled by Type 1 (IFN-gamma, IL-12) and Type 2 (IL-4, IL-10) cytokines which dictate immune response polarization to cell-mediated (CMI) or antibody-mediated immunity (AMI), respectively.
3161 12798635 Immunoglobulin isotype production by porcine B-cells cultured in the presence of recombinant porcine (rp) cytokines varies by individual, however pigs tend to generate a high IgG(1):IgG(2) ratio in response to rp IL-10 and the inverse in response to rp IFN-gamma or rp IL-12.
3162 12798646 Regional recruitment of dendritic cells (DCs) by the local administration of granulocyte macrophage-colony stimulating factor (GM-CSF) or Flt3-ligand (Flt3L) has vaccine adjuvant activity.
3163 12798646 Flow cytometric studies demonstrate that the LN-infiltrating DC is mainly of the CD11c(+)CD11b(-) phenotype (IL-12 producing).

3178 12810878 This study shows that inactivated parapoxvirus ovis (Orf virus), strain D1701 (PPVO), induces an autoregulatory cytokine response that involves the upregulation of IL-12, IL-18, IFN-gamma and other T helper 1-type cytokines and their subsequent downregulation, which is accompanied by induction of IL-4.

3183 12811846 PTx or the B-oligomer of PTx (PTxB) failed to activate purified murine CD4+ or CD8+ T cells, as measured by a lack of proliferation or expression of early T cell activation markers.
3184 12811846 However, these T cells proliferated extensively in response to the toxin in the presence of syngeneic DC, and proliferation was accompanied by a high level of IFN-gamma production in the absence of IL-12.

3188 12839960 Release of IL-12 was necessary to induce potent Tc(1) cells, because DCs from IL-12p40(-/-) mice, irrespective of their maturation level, generated low CTL responses, comparable with 48hDCs and 0hDCs from wild-type animals.
3189 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.
3190 12850812 Granulocyte-macrophage colony-stimulating factor (GM-CSF) enhances immune responses by inducing the proliferation, maturation, and migration of dendritic cells, and the expansion and differentiation of B and T lymphocytes.
3191 12850812 The early response was characterized by high levels of inflammatory molecules, including IL-1beta, IL-6, TNFalpha, RANTES, MIP-1alpha and MCP-1, later followed by expression of precursor Th1 cytokines, IL-12 and IL-18, concomitant with IFNgamma production.
3192 12853397 Considering the critical role of the axis interleukin-12-IFN-gamma for protection from pertussis, our results suggest that testing the induction of a key protective cytokine such as IFN-gamma could be an additional tool for the evaluation of the immune response induced by aP vaccines.
3193 12856223 Clinical tuberculosis in 2 of 3 siblings with interleukin-12 receptor beta1 deficiency.
3194 12856223 We describe 3 siblings with interleukin-12 receptor beta1 (IL-12Rbeta1) deficiency, a known genetic etiology of clinical disease caused by infection with poorly virulent mycobacteria, such as mycobacteria found in bacille Calmette-Guérin (BCG) vaccines and environmental nontuberculous mycobacteria (NTM).

3197 12871182 Nasally administered cytokines such as IL-1 and IL-12 or chemokines including RANTES, lymphotactin, MIP-1 beta, all act as mucosal adjuvants for co-administered antigens.
3198 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.
3199 12874015 DCs generated from peripheral blood using granulocyte macrophage colony-stimulating factor and interleukin (IL)-4 showed immunophenotypes consistent with immature DCs (iDCs).
3200 12874015 Furthermore, OK-DCs showed significantly higher production of IL-12 and IFN-gamma compared with DCs with other stimulations.
3201 12874015 Furthermore, OK-432 does not activate nuclear factor kappaB through Toll-like receptor 2 or Toll-like receptor 4 in the indicator cell system; however, it induces IL-12 production through the beta(2) integrin system on DCs.
3202 12874015 DCs generated from peripheral blood using granulocyte macrophage colony-stimulating factor and interleukin (IL)-4 showed immunophenotypes consistent with immature DCs (iDCs).
3203 12874015 Furthermore, OK-DCs showed significantly higher production of IL-12 and IFN-gamma compared with DCs with other stimulations.

3205 12874303 After 2 to 4 weeks, L. amazonensis-infected mice had significantly delayed and depressed expression of inflammatory cytokines (interleukin-12 [IL-12], gamma interferon, IL-1 alpha, IL-1 beta), CC chemokines (CC chemokine ligand 3 [CCL3]/macrophage inflammatory protein 1 alpha [MIP-1 alpha], CCL4/MIP-1 beta, CCL5/RANTES, MIP-2), and chemokine receptors (CCR1, CCR2, CCR5) in foot tissues and draining lymph nodes compared to the expression in L. major-infected controls.
3206 12874303 Studies with gene knockout mice suggested that IL-10, but not IL-4, contributed partially to compromised immunity in L. amazonensis-infected hosts.
3207 12874362 Rpf-like proteins elicit immunoglobulin G1 (IgG1) and IgG2a responses and T-cell proliferation and stimulate production of gamma interferon, interleukin-10 (IL-10), and IL-12 but not IL-4 or IL-5.
3208 12874361 Immunized mice treated with IL-12 demonstrated increased expression of lung and splenic gamma interferon and IL-10 mRNAs; high levels of antibody, particularly serum immunoglobulin G2a (IgG2a) and respiratory IgA; and significantly increased opsonic activity.
3209 12892730 However, high levels of IL-6, IL-12, and TNFalpha production 2-3 months after intraperitoneal injection appeared to be associated with the ability to induce lupus autoantibodies.
3210 12922098 Co-injection of Hsp65 DNA with IL-12 or GM-CSF led to an increase in IFN-gamma production and represented potent protections against Mycobacterium tuberculosis challenge, while that with Eta-1, IL-12 or IL-18 gene led to an elevated IgG2a/IgG1 ratio.
3211 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.
3212 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.
3213 12933845 The present study was therefore designed to test the hypothesis that the NT region of RAP-1, used as a vaccine with interleukin-12 and RIBI (catalog no.
3214 12933862 Prior to challenge infection, immunization of genetically susceptible A/J mice with the combination of malaria antigen plus recombinant interleukin-12 (IL-12) in alum induced a Th1 immune response with production of high levels of gamma interferon (IFN-gamma) and diminished IL-4 levels by spleen cells stimulated in vitro with parasite antigen compared to mice immunized with antigen alone, antigen in alum, or antigen plus IL-12.
3215 12933862 Protective immunity was dependent on CD4(+) T cells, IFN-gamma, and B cells and was long-lasting.
3216 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.

3233 13680192 Peripheral blood monocytes were cultured in the presence of granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 4 (IL-4) to induce differentiation of DCs.
3234 13680192 Coculture of these DCs and ATs induced significant production of interleukin 12 (IL-12) and also enhanced the production of interferon gamma (IFN-gamma).
3235 13680192 Furthermore, coculture of DCs and ATs induced DCs to upregulate CD83 expression and stimulated migration of DCs toward the macrophage inflammatory protein 3-beta (MIP-3beta).
3236 14505912 Surprisingly, IL-12 had a negligible adjuvant effect when co-injected with HBsAg; however, when bound to "alum", IL-12 stimulated a dramatic increase in anti-HBs titers and a switch from a TH2 to a TH1 response profile as evidenced by an increase in IgG2a subclass anti-HBs antibodies and the ability to secrete interferon-gamma (IFN-gamma) upon in vitro stimulation with an HBs peptide.
3237 14517689 Macrophages isolated from mice immunised with native or plant-expressed CTB showed enhanced secretion of interleukin-10 but secretion of lipopolysaccharide-induced interleukin-12 and tumor necrosis factor alpha was inhibited.

3256 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.
3257 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.

3310 14624382 To determine the effect of IL-12 supplementation, rhesus macaques were vaccinated with a recombinant MV expressing IL-12; these macaques had increased interferon-gamma production by CD4(+) T cells, decreased production of IL-4, and lower levels of MV-specific immunoglobulin G4 and neutralizing antibody.
3311 14627128 Immature monocyte-derived dendritic cells (imMo-DCs) isolated from human peripheral blood monocytes stimulated with granulocyte-macrophage colony stimulating factor and interleukin-4 were exposed to maturation factors, i.e., lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-alpha) plus prostaglandin E2 (PGE2), and OK-432 for 2 days.

3314 14627128 Neutralizing antibody against IL-12 p70 blocked IFN-gamma secretion from OK-432-stimulated Mo-DCs.

3317 14627128 These results indicate that uptake of OK-432 by imMo-DCs is an early critical event for IL-12 p70 production and that NF-kappaB activation induced by OK-432 also contributes partially to IL-12 p70 production.
3318 14627128 Immature monocyte-derived dendritic cells (imMo-DCs) isolated from human peripheral blood monocytes stimulated with granulocyte-macrophage colony stimulating factor and interleukin-4 were exposed to maturation factors, i.e., lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-alpha) plus prostaglandin E2 (PGE2), and OK-432 for 2 days.

3346 14634094 Protection depended on the presence of costimulatory molecules CD80, CD86, and CD40 on the DCs, but surprisingly did not require DCs that could make IL-12 or IL-15.
3347 14634094 As NK cells lack memory, we found by depletion that CD4(+) not CD8(+) T cells were required for induction of the NK antitumor response.
3348 14638790 Nevertheless, bacterial counts in infected lungs, immunohistochemistry, and reverse transcription-PCR analysis of mRNAs for tumor necrosis factor alpha (TNF-alpha), gamma interferon (IFN-gamma), interleukin-1beta (IL-1beta), IL-6, IL-12, and inducible nitric oxide synthase (iNOS) revealed significant differences among the strains.
3349 14638790 At 72 h postinfection, M90T guaBA purHD still induced proinflammatory cytokines and factors such as IL-1beta, IL-6, TNF-alpha, and iNOS, along with cytokines such as IL-12 and IFN-gamma.

3352 14639620 Patients had been treated within 2 clinical trials with autologous tumor cells gene-modified for IL-7 or IL-12.
3353 14639620 Besides 2 known cancer-germline genes (SCP-1 and PLU-1), the other isolated antigens were expressed in a non-tumor-specific fashion as analyzed by virtual Northern blot or RT-PCR.
3354 14639620 The properties of homologues to several of the identified tumor-antigens, especially PLU-1, SCP-1, DNEL2, CLOCK, and PIASx-alpha, suggest further investigation of their possible function in malignant melanoma.
3355 14647233 Concurrent delivery of tumor antigens and activation signals to dendritic cells by irradiated CD40 ligand-transfected tumor cells resulted in efficient activation of specific CD8+ T cells.
3356 14647233 To improve the efficacy of tumor cell-based and dendritic cell (DC)-based cancer vaccines, this study explored the potential of a new cancer vaccine strategy, that is, the use of CD40 ligand-transfected tumor (CD40L-tumor) cells to simultaneously deliver both tumor-derived antigens (Ag) and maturation stimuli to DCs.
3357 14647233 However, during the internalization process, only coculturing with irradiated CD40L-tumor cells resulted in concurrent, optimal DC maturation and production of proinflammatory chemokines and pro-Th1 cytokines, such as IL-6, IL-8, IL-12, IFN-gamma, and TNF-alpha.
3358 14670333 IL-12 enhances protective immunity in mice engendered by immunization with recombinant 14 kDa Schistosoma mansoni fatty acid-binding protein through an IFN-gamma and TNF-alpha dependent pathway.
3359 14670333 Regarding other cytokines, significant amounts of IFN-gamma were measured in splenocyte culture supernatants of rSm14/IL-12 or rSm14 vaccinated mice and no IL-4 was detected.
3360 14670333 In an attempt to determine the role of IFN-gamma and TNF-alpha in IL-12 induced immunity, IFN-gamma and TNFR-p55 knockout mice were immunized with rSm14/IL-12 and no protection was achieved.
3361 14670333 Therefore, protection induced by rSm14/IL-12 was shown to be dependent on endogenous IFN-gamma and TNF-alpha.
3362 14670350 These components include T cells (both CD4+ and CD8+), cytokines, including IFN-gamma, IL-12, TNF-alpha, and IL-6, and macrophages.
3363 14671102 Delivery of plasmid IL-12 on day 10 postimmunization resulted in a robust expansion of gp120-specific CD8+ T cells, as measured by tetramer, gamma interferon ELISPOT, and functional-killing assays.
3364 14671102 Interestingly, this delayed administration of plasmid IL-12 had no significant effect on antigen-specific CD4(+)-T-cell and antibody responses.

3367 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.
3368 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.
3369 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.
3370 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.
3371 14692533 Studies were therefore conducted with murine myeloma BM1 cells expressing Flt3L (membrane bound or soluble forms) or GM-CSF and the IL-12 x CD80 combination.
3372 14692533 All gene-modified BM1 cells, except BM1/IL-12 x CD80, developed tumors when subcutaneously injected into BALB/c mice.

3387 14704372 T cells from mice immunized with antigen in the presence of CT produced high levels of interleukin (IL)-10 and IL-5 and low levels of IL-4 and interferon-gamma (IFN-gamma).
3388 14704372 Here, we demonstrate that immunization with antigen in the presence of CT induced a population of antigen-specific CD4(+) T cells that produced IL-10 in the absence of IL-4, in addition to cells that coexpressed IL-4 and IL-10 or produced IL-4 only.
3389 14704372 Previous data showed that CT can modulate the expression of costimulatory molecules and inhibit the production of chemokines and cytokines, including IL-12 and tumor necrosis factor alpha and enhance IL-10 production.
3390 14704372 Here, we show that CT synergizes with LPS to induce IL-6 and IL-1beta in addition to IL-10 production by immature DC.
3391 14722672 Natural immunity boosted by IL-12 and IL-2 significantly hampers the progression of mammary lesions occurring in HER-2/neu transgenic mice genetically predestined to develop lethal mammary carcinomas.
3392 14734758 Distinct modulatory effects of LPS and CpG on IL-18-dependent IFN-gamma synthesis.
3393 14734758 C3H/HeN mice pretreated with LPS for 2 days generated 5-fold less circulating IL-12 p70 and IFN-gamma in response to subsequent LPS challenge than did challenged control mice.
3394 14734758 In contrast, CpG-pretreated mice produced 10-fold more circulating IFN-gamma without similar changes in IL-12 p70 levels, but with 10-fold increases in serum IL-18 relative to LPS-challenged control or endotoxin-tolerant mice.
3395 14734758 Finally, combined pretreatment of mice with LPS and CpG suppressed the production of circulating IFN-gamma, IL-12 p70, and IL-18 after subsequent LPS challenge.
3396 14734758 We conclude that CpG potentiates innate IFN-gamma production from NK cells by increasing IL-18 availability, but that the suppressive effects of LPS on innate cellular immunity dominate during combined LPS and CpG pretreatment.
3397 14738450 In addition, the direct effects of high-dose IL-12 on challenged mice was assessed by checking natural killer (NK) activity from isolated lung and spleen lymphoid cells as well as interferon-gamma (IFN-gamma) generation from isolated cells and serum at day 1 post-challenge.
3398 14738463 IL-12 enhances the generation of tumour antigen-specific Th1 CD4 T cells during ex vivo expansion.
3399 14738463 The effects of IL-12, along with IL-2, on the ex vivo generation of HER-2/neu antigen-specific T cells were examined.
3400 14738463 The resulting p776-790-specific T cells responded readily to antigen by proliferating and producing type I cytokines (IFN-gamma and TNF-alpha).
3401 14738463 These results suggest that IL-12 is an important cytokine for ex vivo recovery and maintenance of antigen-specific CD4+ T lymphocytes that would otherwise be lost by using IL-2 alone in combination with antigen.

3406 14741165 The addition of interferon-gamma (IFN-gamma) augmented IL-12 production.
3407 14741165 RT-PCR showed that SAKRA induced not only expression of IL-12 p40 mRNA, but expression of tumor necrosis factor (TNF)-alpha and inducible nitric oxide synthase (iNOS) mRNA at least 6 h after stimulation, suggesting that SAKRA activates the bactericidal activity of macrophages.
3408 14741165 The addition of interferon-gamma (IFN-gamma) augmented IL-12 production.
3409 14741165 RT-PCR showed that SAKRA induced not only expression of IL-12 p40 mRNA, but expression of tumor necrosis factor (TNF)-alpha and inducible nitric oxide synthase (iNOS) mRNA at least 6 h after stimulation, suggesting that SAKRA activates the bactericidal activity of macrophages.
3410 14742540 In vivo depletions of interleukin-12 and gamma interferon cytokines and CD4+ and CD8+ T cells in vaccinated mice had no significant effect on immunity.
3411 14744795 BCG-CWS was capable of activating DCs ex vivo by the criteria of CD80/CD86 up-regulation and cytokine (interleukin-12, tumor necrosis factor-alpha) induction.

3413 14987409 Mutations have been identified in five genes in the interleukin-12-dependent interferon-gamma pathway, highlighting the importance of this pathway in human mycobacterial immunity.
3414 14991620 In vitro stimulation of immature murine DC with MALP-2 resulted in the induction of maturation with up-regulated expression of MHC class II, costimulatory (CD80, CD86) and adhesion (CD40, CD54) molecules.
3415 14991620 MALP-2 also enhances the secretion of cytokines (IL-1alpha, IL-6 and IL-12), and increases DC stimulatory activity on naive and antigen-specific T cells.
3416 14991620 Further studies demonstrated that MALP-2 treatment of DC results in a dose-dependent shift from the protein pattern of proteasomes to immunoproteasomes (up-regulation of LMP2, LMP7 and MECL1), which correlates with an increased proteolytic activity.
3417 14991651 The biological activity of plant-produced IL-12 was determined by interferon gamma (IFN-gamma) production by natural killer (NK) cells, and the level of production was comparable to that obtained with commercially available recombinant IL-12.

3422 15007094 Combined TLR and CD40 triggering induces potent CD8+ T cell expansion with variable dependence on type I IFN.
3423 15007094 Whereas agonists for either pathway have been used as vaccine adjuvants, we show that a combination of Toll-like receptor (TLR)7 and CD40 agonists synergize to stimulate CD8+ T cell responses 10-20-fold greater than the use of either agonist alone.
3424 15007094 Antigen-specific CD8+ T cells elicited from combination CD40/TLR7 treatment demonstrated both lytic activities and interferon (IFN)gamma production and an enhanced secondary response to antigenic challenge.
3425 15007094 The CD8+ T cell expansion induced by CD40/TLR7 triggering was independent of CD4+ T cells, IFNgamma, and IL-12 but dependent on B7-mediated costimulation and surprisingly on type I IFN.
3426 15007640 In this study, we evaluate the Th1/Th2 profile (Th1: IL-12, IFN-gamma; Th2: IL-6, IL-10) in response to protoscoleces, EgA31 and the mixture of EgA31, EgTrp and FABP1.
3427 15007640 Neither IFN-gamma nor IL-6, but a significant IL-10 and IL-12 concentration was detected in response to both types of antigens.

3430 15010228 However, live bacteria induced greater up-regulation of the expression of CD40 and CD86 than killed bacteria.
3431 15010228 Live bacteria also induced greater up-regulation of transcription for IL-6, IL-12 and GM-CSF than killed bacteria as measured by quantitative RT-PCR.
3432 15011756 According to the research group of Shortman, experimental results suggest a "dual" DC differentiation model, demonstrating the existence of both myeloid-derived (with characteristic IF: CD11b+, CD11c+, CD8alpha- and DEC205+) and lymphoid-derived DCs (showing CD11b- CD11c-, CD8alpha+ and DEC205+ IF).
3433 15011756 Most of the DCs express immunocytochemically detectable antigens like: S-100, CD1a, CD40 receptor, adhesion molecules (ICAM-1 or CD54, LFA-1 and LFA-3), integrins (CD11a, CD11c and CD18), CD45, CD54, co-stimulatory molecules (B7-1 or CD80, B7-2 or CD86), F418, MHC class I and II and DEC-205, multilectin receptor, immunostimulatory cytokine (IL-12) and, of course, Fc and complement receptors.
3434 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).
3435 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.
3436 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.
3437 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.
3438 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.
3439 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.
3440 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).
3441 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.
3442 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.
3443 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.
3444 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.
3445 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.

3457 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.
3458 15034009 Among other tested RNAs, only polyuridylic acid induced IL-12 p70.
3459 15034009 RNA-transfected APC also polarize T cells in an IL-12-dependent manner toward the IFN-gamma(high)IL-5 (low) Th1 phenotype, suggesting a link between the detection of appropriately structured RNA and the skewing of immune responses toward those best suited for controlling intracellular microbes.
3460 15039522 Host-dependent type 1 cytokine responses driven by inactivated viruses may fail to default in the absence of IL-12 or IFN-alpha/beta.
3461 15039522 Strikingly, immunizations in gene-disrupted mice showed that a functional IFN-alpha/beta, IFN-gamma or interleukin (IL)-12 pathway was not required for the generation of a polarized Th1 type immune response initiated by inactivated virus particles.
3462 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.
3463 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.
3464 15064826 Susceptibility involves IL-10 but not IL-4, and B cells.
3465 15064826 In immune animals, upon re-infection, the elements involved in resistance are different, i.e., CD8+ T cells and IL-2.
3466 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.
3467 15070823 Our results show that both apoptotic preparations were equivalent regarding the responsiveness of DCs to combined treatment with tumor necrosis factor-alpha and poly(inosinic-cytidylic) acid, as determined by similar increased expression of costimulatory molecules and interleukin-12 production.
3468 15075365 Flt3L-mobilized DCs exhibited slightly increased CD80/CD86 expression but typically still that of immature DCs and were resilient to freeze-thawing.
3469 15075365 Overnight culture activated the cells, up-regulating CD80/CD86 expression as well as interleukin-12 release, typically being boosted by CD40L.
3470 15094367 After intravenous administration, OVA mRNA expression and MHC class I-restricted antigen presentation on CD11c+ cells and inflammatory cytokines, such as TNF-alpha, IL-12, and IFN-gamma, that can enhance the Th1 response of the Man liposome/pCMV-OVA complex were higher than that of naked pCMV-OVA and that complexed with DC-Chol liposomes.
3471 15099760 The ingestion of MS did not change the cell surface expression of CD80, CD83, CD86 and HLA-DR of immature and mature DC, suggesting that MS uptake did not induce DC maturation but that maturation by cytokines or LPS was unaltered in the presence of MS.
3472 15099760 Furthermore, MS-loaded mature MoDC expressed normal levels of the chemokine receptor CCR7 and migrated as efficiently towards CCL19 or CCL21 as unloaded MoDC.
3473 15099760 DC viability and the secretion of TNF-alpha and IL-12 was not significantly changed by MS loading.
3474 15100252 Paracrine release of IL-12 stimulates IFN-gamma production and dramatically enhances the antigen-specific T cell response after vaccination with a novel peptide-based cancer vaccine.
3475 15100252 The enhanced immune response was significantly reduced in IFN-gamma(-/-) and IL-12R beta 2(-/-) recipient mice suggesting that the role of IL-12 is mediated, at least in part, by host cells.
3476 15100252 Paracrine release of IL-12 stimulates IFN-gamma production and dramatically enhances the antigen-specific T cell response after vaccination with a novel peptide-based cancer vaccine.
3477 15100252 The enhanced immune response was significantly reduced in IFN-gamma(-/-) and IL-12R beta 2(-/-) recipient mice suggesting that the role of IL-12 is mediated, at least in part, by host cells.
3478 15102698 DC-AdCCL21 administration led to increases in the CD4(+), CD8(+), and CD3(+)CXCR3(+) T cells, as well as DC expressing CD11c(+) DEC205(+).
3479 15102698 CD4(+)CD25(+) T-regulatory cells infiltrating the tumors were markedly reduced after DC-AdCCL21 therapy.
3480 15102698 The tumor site cellular infiltrates were accompanied by the enhanced elaboration of granulocyte macrophage colony-stimulating factor, IFN-gamma, MIG/CXCL9, IP-10/CXCL10, and interleukin 12, but decreases in the immunosuppressive mediators transforming growth factor beta and prostaglandin E(2).
3481 15102698 In vivo depletion of IP-10/CXCL10, MIG/CXCL9, or IFN-gamma significantly reduced the antitumor efficacy of DC-AdCCL21.
3482 15115073 The expression of SjC23 and p35, p40 in muscle tissue was determined by immunohistochemical method.
3483 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).

3494 15121297 Acute Trypanosoma cruzi infection: IL-12, IL-18, TNF, sTNFR and NO in T. rangeli-vaccinated mice.
3495 15121297 The aim of the present work was to complete our previous study on the production of IFN-gamma and IL-10 in this vaccination model by investigating the production of IL-12p35 and p40, IL-18, TNF, TNF soluble receptors (sTNFR), and nitric oxide (NO), factors known to play a key role in the outcome of T. cruzi infection.
3496 15128786 Both vectors induced IL-12 and TNF-alpha, but only Lm-LLO-E7 induced IL-2 production by DCs.
3497 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.
3498 15128786 A similar shift is also observed for B7-H1 and B7-DC molecules.
3499 15138584 The secondary response in the peritoneal cavity involved a >80-fold enrichment of epitope specific CD8+ T cells and the release of various cytokines, including IL-12 and TNF-alpha.
3500 15147716 Several abnormalities of the immune system have been described, including changes in lymphocyte number and function, shifts in cytokine responses, immunomodulatory effects of interleukin-10, down regulation of interleukin-12, impaired antigen presentation, and altered interferon alpha/beta signaling pathways.
3501 15149772 Surprisingly, antigen free-Planococcus liposomes evoked potent non-specific inflammatory cytokine production (IL-12 and IL-6) by dendritic cells whereas archaeal H. volcanii vesicles evoked little inflammatory cytokines.
3502 15150328 Transfer of specific antibodies results in increased expression of TNF-alpha and IL12 and recruitment of neutrophils to the site of a cutaneous Francisella tularensis infection.
3503 15150328 Recipient mice showed stronger staining for TNF-alpha and IL12, and larger numbers of neutrophils in skin samples after infection than control mice.

3506 15158187 In this work, we used a murine model of systemic C. albicans infection, in which resistance to reinfection with virulent wild-type cells is induced by prior exposure of mice to a low-virulence agerminative strain of C. albicans (primary sublethal infection), to study the influence of TLR2 gene deletion on (i) the ability to develop an acquired resistance upon vaccination; (ii) the development of the acquired humoral response; and (iii) the production of Th1 cytokines IFN-gamma, IL-12 and TNF-alpha.
3507 15161079 To examine the effects of cytokine environment at the time of antigenic exposure on T-cell cytokine profiles following T-cell-antigen presenting cell (APC) interaction, pig monocyte-derived dendritic cells (mDCs) were treated with hen egg white lysozyme (HEWL) or killed Mycobacterium tuberculosis (Mtb) alone or with a recombinant pig cytokine (TNF-alpha, interleukin (IL)-12, IL-10, interferon (IFN)-gamma or IL-6) and then incubated with autologous T-cell-enriched lymphocytes.
3508 15161079 Messenger RNA was isolated from the T-cells and used to evaluate the effects of treatment on IL-12p35, IFN-gamma, IL-4, IL-10 and IL-13 expression using RT-PCR.
3509 15161079 T-cells exposed to HEWL-treated mDCs expressed high IL-13 and moderate IL-10 and IFN-gamma, suggesting T-helper 2 (Th-2) bias.
3510 15161079 Addition of any cytokine during HEWL treatment of mDCs reduced subsequent expression of IL-10 and IL-13 by T-cells.
3511 15161079 Added IL-12 increased IFN-gamma mRNA.
3512 15161079 T-cells exposed to Mtb-treated mDCs expressed increased IFN-gamma and decreased IL-10 suggesting Th-1 bias.
3513 15161079 Addition of cytokines to mDCs treated with Mtb altered T-cell cytokine mRNA expression such that TNF-alpha, IFN-gamma or IL-12 increased IFN-gamma; IL-12 and IFN-gamma suppressed IL-10, while IL-10 and IL-12 enhanced IL-13.

3521 15162438 RNA interference technology has been used to modulate dendritic cell (DC) function by targeting the expression of genes such as IL-12 and NF-kappa B.
3522 15162438 Inhibition of IL-10 by siRNA was accompanied by increased CD40 expression and IL-12 production after maturation, which endowed DC with the ability to significantly enhance allogeneic T cell proliferation.
3523 15162438 IL-10 siRNA transfection did not affect MHC class II, CD86, CD83, or CD54 expression in mature DC.
3524 15162438 To further test the ability of IL-10 siRNA-treated DC to induce a T cell response, naive CD4 T cells were stimulated by autologous DC pulsed with KLH.

3533 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.
3534 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.
3535 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.
3536 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.

3552 15181281 Thus, interleukin-4 (IL-4) is known to induce IL-4 production in T cells; conversely IL-12 and interferon-gamma (IFN-gamma) are known to induce IFN-gamma production by T cells.
3553 15185348 Modulation by factors that affect T-cell function or hematopoiesis, including interleukin-12, interleukin-15, interleukin-18, interleukin-23, Eta-1, Flt3L and GM-CSF, was studied in the forms of monocistronic and bicistronic plasmid.
3554 15185348 Our results demonstrated that vaccination of pHM could induce successful antitumor immunity against Her-2/neu-expressing murine tumor cells in BALB/c mice.
3555 15185348 In particular, coexpression of interleukin-18 or GM-CSF with Her-2/neu increased antitumor activity in both preventive and therapeutic experiments.
3556 15186399 We show here that optimal IL-12 and TNF-alpha production by human monocyte derived DC in response to killed serogroup B N. meningitidis depends on physical contact and internalization of the bacteria by DC.
3557 15186399 The majority of DC producing cytokines had internalized N. meningitidis while inhibition of bacterial internalization markedly impaired IL-12 and TNF-alpha, but not IL-6 production.
3558 15186399 Restoration of LOS biosynthesis in a LOS regulatory strain also restored both internalization and cytokine production and was enhanced in the presence of LPS binding protein (LBP).
3559 15186399 We show here that optimal IL-12 and TNF-alpha production by human monocyte derived DC in response to killed serogroup B N. meningitidis depends on physical contact and internalization of the bacteria by DC.

3562 15194169 Induction of these autoantibodies appeared to be associated with the hydrocarbon's ability to induce IL-12, IL-6, and TNF-alpha, suggesting a relationship with hydrocarbon's adjuvanticity.
3563 15196240 IFN-gamma production by splenocytes was eliminated by addition of neutralizing anti-IL-18 antibody.
3564 15196240 Endogenous IL-12 played a favourable role whereas IL-10 played an adverse role in rBCG-mIL-18-induced IFN-gamma production.
3565 15196240 Further, splenocytes from rBCG-mIL-18-infected mice, in response to BCG antigen, displayed increased production of IFN-gamma and GMCSF, decreased production of IL-10, elevated cellular proliferation and higher differentiation of IFN-gamma-secreting cells. rBCG-mIL-18 also enhanced BCG-induced macrophage cytotoxicity against bladder cancer MBT-2 cells in a dose-dependent manner.
3566 15196240 Neutralizing all endogenous macrophage-derived cytokines tested (IL-12, IL-18 and TNF-alpha) as well as IFN-gamma severely diminished the rBCG-mIL-18-induced macrophage cytolytic activity, indicating a critical role for these cytokines in this process.
3567 15196240 Cytokine analysis for supernatants of macrophage-BCG mixture cultures manifested higher levels of IFN-gamma and TNF-alpha in rBCG-mIL-18 cultures than in control BCG cultures.
3568 15196240 IFN-gamma production by splenocytes was eliminated by addition of neutralizing anti-IL-18 antibody.
3569 15196240 Endogenous IL-12 played a favourable role whereas IL-10 played an adverse role in rBCG-mIL-18-induced IFN-gamma production.
3570 15196240 Further, splenocytes from rBCG-mIL-18-infected mice, in response to BCG antigen, displayed increased production of IFN-gamma and GMCSF, decreased production of IL-10, elevated cellular proliferation and higher differentiation of IFN-gamma-secreting cells. rBCG-mIL-18 also enhanced BCG-induced macrophage cytotoxicity against bladder cancer MBT-2 cells in a dose-dependent manner.
3571 15196240 Neutralizing all endogenous macrophage-derived cytokines tested (IL-12, IL-18 and TNF-alpha) as well as IFN-gamma severely diminished the rBCG-mIL-18-induced macrophage cytolytic activity, indicating a critical role for these cytokines in this process.
3572 15196240 Cytokine analysis for supernatants of macrophage-BCG mixture cultures manifested higher levels of IFN-gamma and TNF-alpha in rBCG-mIL-18 cultures than in control BCG cultures.

3576 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.
3577 15240755 We found that monocytes infected with BCG differentiate into CD1a- DCs (BCG-DCs) in the presence of granulocyte macrophage-colony stimulating factor and interleukin (IL)-4 and acquired a mature phenotype in the absence of maturation stimuli.
3578 15240755 In addition, BCG-DCs produced proinflammatory cytokines (tumor necrosis factor alpha, IL-1beta, IL-6) and IL-10 but not IL-12.

3583 15265893 A CpG-B ISS-ODN increased CD80/CD86 expression by PDCs, but resulted in little IFN-alpha secretion unless IL-3 was added.
3584 15265893 In contrast, a CpG-C ISS-ODN and aldrithiol-2-inactivated (AT-2) SIV induced considerable PDC activation and IFN-alpha release without needing exogenous IL-3.
3585 15265893 The CpG-C ISS-ODN also stimulated IL-12 release (unlike AT-2 SIV) and augmented DC immunostimulatory activity, increasing SIV-specific T cell IFN-gamma production induced by AT-2 SIV-presenting MDC/PDC-enriched mixtures.
3586 15265893 These data highlight the functional capacities of MDCs and PDCs in naive as well as healthy, infected macaques, revealing a promising CpG-C ISS-ODN-driven DC activation strategy that boosts immune function to augment preventative and therapeutic vaccine efficacy.

3597 15270693 Since the receptor for HSP70 is CD40, which with its CD40 ligand constitutes a major co-stimulatory pathway in the interaction between antigen-presenting cells and T-cells, HSP70 may function as an alternative ligand to CD40L.
3598 15271962 DNA vaccines promote T helper 1 (Th1) responses by triggering interleukin-12 (IL-12) release by dendritic cells (DC) through Toll-like receptor 9 (TLR9).

3620 15322018 Although the activity of phosphatidylinositol dimannoside was little influenced by palmitoylation of mannose at C-6, a further palmitoylation at inositol C-3 diminished the induction levels of IL-6 and IL-12.

3644 15389286 In comparison with DCs transduced with gp100 alone (gp100/DCs), upregulation of major histocompatibility complex class I, CD40, and CD86 molecules on the cell surface and more potent T-cell-stimulating ability for proliferation and interferon-gamma secretion were observed as characteristic changes in gp100+IL12/DCs.

3677 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.
3678 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.
3679 15485577 An EuTDA cytotoxicity assay was used to compare cytotoxic activities of IL-2 and/or IL-12 stimulated PBMC against unmodified lymphoma cells.
3680 15485577 Adenoviral-expressed IL-2 and IL-12 similarly led to dose-dependent increases in proliferation rates of PBMC obtained from healthy donors.

3749 15507313 To improve the immune response, an adjuvant consisting of plasmid encoding either porcine interleukin (IL)-12 or IFN-alpha was co-administered during vaccination.
3750 15507313 While this enhancement was only transient (1 week) when the IL-12 expressing plasmid was used, the effect was not only still apparent at 6 weeks after vaccination in the presence of the IFN-alpha expressing plasmid but even after challenge with a virulent genetically divergent PRRSV.
3751 15507313 Despite the apparent augmentation of a T helper (Th) 1 type response by the inclusion of IFN-alpha or IL-12 during vaccination, this modulation did not necessarily correlate with a reduction in viremia.

3797 15557182 Following acute viral infection, 70-80% of virus-specific T cells will produce IFN-gamma after exposure to LPS-induced cytokines, and neutralization experiments indicate that this is mediated almost entirely through production of IL-12 and IL-18.

3816 15557182 Different combinations of these cytokines revealed that IL-12 decreases the threshold of T cell activation by IL-18, presenting a new perspective on IL-12/IL-18 synergy.
3817 15557182 Moreover, memory T cells demonstrate high IL-18R expression and respond effectively to the combination of IL-12 and IL-18, but cannot respond to IL-18 alone, even at high cytokine concentrations.
3818 15557182 This demonstrates that the synergy between IL-12 and IL-18 in triggering IFN-gamma production by memory T cells is not simply due to up-regulation of the surface receptor for IL-18, as shown previously with naive T cells.

3825 15574787 In contrast with the NKT cell agonist alpha-galactosylceramide, which induces both IFN-gamma and IL-4 production by NKT cells, CpG-liposome only induced IFN-gamma production by NKT cells.
3826 15574787 In addition to TLR9, at least two other factors, IL-12 production by DCs and direct contact between DCs and NK or NKT cells, were essential for inducing type 1 innate immunity by CpG-liposome.
3827 15582662 Rescue of memory CD8+ T cell reactivity in peptide/TLR9 ligand immunization by codelivery of cytokines or CD40 ligation.
3828 15582662 Here, we show that immunization of mice with SSIEFARL peptide (immunodominant epitope in glycoprotein B of herpes simplex virus type 1, aa498-505) combined with TLR9 ligand in the absence of helper CD4(+) T cell activation generates a functionally impaired CD8(+) T cell memory response.
3829 15582662 Codelivery of IL-12, IL-15, or anti-CD40 together with MHC class-I-restricted peptide combined with TLR9 ligand at inception of immunization resulted in generation of memory CD8(+) T cells that were several fold less compromised than immunization with peptide alone.
3830 15582662 Furthermore, administration of either plasmid DNA encoding IL-15 or anti-CD40 mAb but not rIL-12 during the memory phase restored the reactivity of memory CD8(+) T cells.
3831 15597328 CpG also induces IL-12, TNF, MCP-1 and macrophage nitric oxide production.

3835 15606336 In the adjuvant setting, cytokine monotherapy (interferon [IFN]-alpha or interleukin [IL]-2) is not effective in improving progression-free or overall survival.
3836 15606336 In metastatic kidney cancer patients with the tumor-bearing kidney in situ, a combination of radical nephrectomy plus IFN-alpha is more effective than IFN-alpha alone.
3837 15606336 In metastatic kidney cancer without the option of operative removal of the primary tumor and/or metastases, cytokines such as IFN-alpha, IL-2 and IL-12 and their combinations result in response rates of 10-30%, but the 5-year overall survival is less than 10%.
3838 15629885 Upon stimulation with LPS, in comparison with young MPhi, aged MPhi secreted reduced amounts of IL-6, tumor necrosis factor alpha, IL-1beta, and IL-12, cytokines necessary for B cells to respond to TI Ag.
3839 15629885 As aged MPhi have a reduced number of cells expressing Toll-like receptor 4 and CD14, the imbalance in cytokine production might be partly a result of fewer cells expressing key components of the LPS receptor complex.
3840 15634897 Dendritic cells and NK cells stimulate bystander T cell activation in response to TLR agonists through secretion of IFN-alpha beta and IFN-gamma.
3841 15634897 In vitro, IFN-alphabeta, IL-18, and IL-12 all contributed to DC stimulation of NK cell IFN-gamma, whereas IFN-alphabeta was shown to be important for induction of T cell bystander activation and NK cell IFN-gamma production in vivo.

3925 15753654 Here, the efficiency of DC transduction by Ad vectors retargeted to DC-specific ICAM-3 grabbing nonintegrin (DC-SIGN) was studied and compared to that of Ad vectors retargeted through CD40.
3926 15753654 A comparable and significant enhancement of gene transfer to monocyte derived DCs (MDDCs) was accomplished by means of an Ad vector harboring the Fc-binding domain of Staphylococcus aureus protein A in combination with antibodies to DC-SIGN or to CD40 or with fused complexes of human Ig-Fc with their natural ligands, i.e., ICAM-3 or CD40L, respectively.
3927 15753654 Whereas CD40-targeted Ad transduction resulted in a more profound phenotypic DC maturation, DC-SIGN- and CD40-targeted Ad both induced similar levels of IL-12 secretion.

3936 15755583 We have developed two novel tuberculosis (TB) vaccines: a DNA vaccine combination expressing mycobacterial heat shock protein 65 (Hsp65) and interleukin-12 (IL-12) by using the hemagglutinating virus of Japan (HVJ)-liposome (HSP65+IL-12/HVJ) and a recombinant BCG harboring the 72f fusion gene (72f rBCG).
3937 15755583 In the present study, we extended our studies to a cynomolgus monkey model, which is currently the best animal model of human tuberculosis, to evaluate the HSP65+IL-12/HVJ and 72f rBCG vaccines.

3944 15777234 The proinflammatory cytokines IL-1alpha, IL-12, and IL-18 can replace CT as a mucosal adjuvant for antibody induction and induce an increase of mucosal CTL's.
3945 15777234 IL-15 also has the potential to increase antigen-specific CTL activity when used as an adjuvant while IL-5 and IL-6 were shown to be able to markedly increase IgA reactivity to co-expressed heterologous antigen.
3946 15780444 The IMOs were significantly more stable than CpG DNA following oral administration, and IMOs induced stronger local and systemic immune responses as determined by MIP-1beta, MCP-1, IP-10, and IL-12 production.
3947 15784575 It was found that gamma interferon (IFN-gamma) and IL-12 were strictly required for protection, since mice deficient in IFN-gamma, IL-12 p35, or IL-12 p40 all succumbed to LVS doses that were sublethal for wild-type mice.
3948 15784575 Furthermore, exogenous IL-12 treatment 24 h before intranasal infection with a lethal dose of LVS (10,000 CFU) significantly decreased bacterial loads in the lungs, livers, and spleens of wild-type BALB/c and C57BL/6 mice and allowed the animals to survive infection; such protection was not observed in IFN-gamma-deficient mice.
3949 15784575 The resistance induced by IL-12 to LVS infection was still observed in NK cell-deficient beige mice but not in CD8-/- mice.
3950 15784575 These results demonstrate that exogenous IL-12 delivered intranasally can prevent respiratory tularemia through a mechanism that is at least partially dependent upon the expression of IFN-gamma and CD8 T cells.

3963 15787742 Murine bone marrow-derived dendritic cells (DC) can be generated by culture in the presence of granulocyte/macrophage colony-stimulating factor (GM-CSF) alone or GM-CSF in conjunction with interleukin-4 (IL-4).
3964 15787742 Also, the four culture conditions generated CD11c+ DC with comparable levels of major histocompatibility complex (MHC) class II, CD40, CD80 and CD86 expression, with the exception of cells cultured under serum-free conditions in the absence of IL-4, which displayed suboptimal levels of these markers.
3965 15787742 However, both DC populations displayed a similar capacity to take up fluorescein isothiocyanate (FITC)-albumin by macropinocytosis and FITC-Dextran by the mannose receptor and to secrete IL-12 in response to stimulation with lipopolysaccharide (LPS) or an agonistic anti-CD40 monoclonal antibody.
3966 15787742 Therefore, we conclude that although both DC culture methods result in the production of DC with similar functional abilities, under serum-free conditions, DC cultured in GM-CSF and IL-4 show an increased stimulatory potential over DC cultured in GM-CSF alone.
3967 15793299 We previously showed that a vaccine combining interleukin 12 and allogeneic p185(neu)-positive mammary carcinoma cells completely prevented multifocal mammary carcinogenesis in HER-2/neu transgenic mice.
3968 15797625 In this study, we investigated the anti-vasculature effects and the antitumor effects of combining attenuated Salmonella typhimurium vaccine strain encoding murine vascular endothelial growth factor (VEGF) receptor-2 (flk1) with plasmid DNA vector encoding the murine interleukin-12 (mIL-12) gene.
3969 15806292 Our preliminary study on the transcription levels of IFN-gamma and IL-4 in splenic CD4+ T cells revealed that attenuated cercariae elicited predominantly a Th1 response in mice at the early stage, whereas normal cercariae stimulated primarily Th2-dependent responses.
3970 15806292 However, for IL-12 and IL-4, the potent inducers of Th1 and Th2 responses, respectively, as well as IL-10, there were no differences over the course of the experiment between the infected and vaccinated mice.
3971 15812230 Nonreplicating recombinant vaccinia virus expressing CD40 ligand enhances APC capacity to stimulate specific CD4+ and CD8+ T cell responses.
3972 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.
3973 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).
3974 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.
3975 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.
3976 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.
3977 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.
3978 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.
3979 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).
3980 15814713 IL-10 deficiency caused early maturation and activation of pulsed DC (i.e., high CD11c, CD40, CD80, CD83, CD86, IL-1, IL-12, and the T cell-attracting chemokine CCL27/CTACK) and consequently an enhanced ability to process and present Ags for a rapid and robust T cell activation.
3981 15814713 Supporting comparative proteomics revealed further that IL-10 deficient DC possess specific immunobiological properties, e.g., the T cell-attracting chemokine CCL27/CTACK, calcium-dependent protein kinase, and the IL-1/IL-12 inducer, NKR-P1A (CD161), which differentiated them immunologically from wild-type DC that express molecules relating to anti-inflammatory, differentiative, and metabolic processes, e.g., the anti-IL-12 molecule peroxisome proliferator-activated receptor-alpha and thymidine kinase.

3984 15824902 By flow cytometry, we have shown that the ratio CD4+/CD8+ of splenocytes were significantly higher in the antigen-immunized groups.
3985 15824902 The production of IL-12, IFN-gamma, IL-10 and IL-6 cytokines was significantly higher in mice immunized with recombinant proteins.
3986 15826816 Treatment of mice with IL-12 DNA constructs leads to augmented NK activity in lungs but low IFN-gamma release -- implications for Bordetella pertussis infections following aerosol challenge.
3987 15828575 Here we report the proliferation of spleen cells in response to the recombinant Sm-p80 protein and cytokine (IFN-gamma and IL-4) production by the splenocytes.
3988 15828575 These spleen cells were obtained from groups of mice that were vaccinated with a DNA vaccine formulation containing Sm-p80 and one of the Th-1 (IL-2 or IL-12) or Th-2 (GM-CSF, IL-4) enhancer cytokines.
3989 15828575 The splenocytes obtained from mice vaccinated with Sm-p80 DNA with Th-1 enhancer cytokines IL-2 and IL-12 provided the highest proliferation.
3990 15828575 The IFN-gamma production by splenocytes was found to follow the similar pattern [(Sm-p80) < (Sm-p80 + IL-4) < (Sm-p80 + GMCSF) < (Sm-p80 + IL-12) < (Sm-p80 + IL-2)], as has been observed for the proliferation and protection data.

3992 15828575 These spleen cells were obtained from groups of mice that were vaccinated with a DNA vaccine formulation containing Sm-p80 and one of the Th-1 (IL-2 or IL-12) or Th-2 (GM-CSF, IL-4) enhancer cytokines.
3993 15828575 The splenocytes obtained from mice vaccinated with Sm-p80 DNA with Th-1 enhancer cytokines IL-2 and IL-12 provided the highest proliferation.
3994 15828575 The IFN-gamma production by splenocytes was found to follow the similar pattern [(Sm-p80) < (Sm-p80 + IL-4) < (Sm-p80 + GMCSF) < (Sm-p80 + IL-12) < (Sm-p80 + IL-2)], as has been observed for the proliferation and protection data.
3995 15845475 Human blood monocyte-derived macrophages, purified from healthy donors, were incubated with each outer membrane constituent, and cytokine production of macrophage supernatants interleukin-1beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha), IL-10, IL-12, and IL-8 was measured.
3996 15845475 OMP P6 selectively upregulated IL-10, TNF-alpha, and IL-8.
3997 15845475 While OMP P6 (0.1 mug/ml for 8 h) elicited slightly greater concentrations of IL-10, it resulted in over ninefold greater concentrations of TNF-alpha and over fourfold greater concentrations of IL-8 than did OMP P2.
3998 15845475 OMP P6 of NTHI is a specific trigger of bacteria-induced human macrophage inflammatory events, with IL-8 and TNF-alpha as key effectors of P6-induced macrophage responses.
3999 15845642 Mycobacterium bovis Bacillus Calmette-Guerin infects DC-SIGN- dendritic cell and causes the inhibition of IL-12 and the enhancement of IL-10 production.
4000 15845642 Recent studies have shown that BCG and Mtb target the DC-specific C-type lectin intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) to infect DC and inhibit their immunostimulatory function.
4001 15845642 This would occur through the interaction of the mycobacterial mannosylated lipoarabinomannan to DC-SIGN, which would prevent DC maturation and induce the immunosuppressive cytokine interleukin (IL)-10 synthesis.
4002 15845642 Here, we confirm that DC-SIGN is expressed in DC derived from monocytes cultured in granulocyte macrophage-colony stimulating factor (GM-CSF) and IL-4 and show that it is not expressed in DC derived from monocytes cultured in GM-CSF and interferon-alpha (IFN-alpha).
4003 15845642 We also demonstrate that DC-SIGN(-) DC cultured in GM-CSF and IFN-alpha are able to phagocytose BCG and to undergo a maturation program as well as DC-SIGN(+) DC cultured in IL-4 and GM-CSF.
4004 15845642 We also show that BCG causes the impairment of IL-12 and the induction of IL-10 secretion by DC, irrespective of DC-SIGN expression.
4005 15845642 Mycobacterium bovis Bacillus Calmette-Guerin infects DC-SIGN- dendritic cell and causes the inhibition of IL-12 and the enhancement of IL-10 production.
4006 15845642 Recent studies have shown that BCG and Mtb target the DC-specific C-type lectin intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) to infect DC and inhibit their immunostimulatory function.
4007 15845642 This would occur through the interaction of the mycobacterial mannosylated lipoarabinomannan to DC-SIGN, which would prevent DC maturation and induce the immunosuppressive cytokine interleukin (IL)-10 synthesis.
4008 15845642 Here, we confirm that DC-SIGN is expressed in DC derived from monocytes cultured in granulocyte macrophage-colony stimulating factor (GM-CSF) and IL-4 and show that it is not expressed in DC derived from monocytes cultured in GM-CSF and interferon-alpha (IFN-alpha).
4009 15845642 We also demonstrate that DC-SIGN(-) DC cultured in GM-CSF and IFN-alpha are able to phagocytose BCG and to undergo a maturation program as well as DC-SIGN(+) DC cultured in IL-4 and GM-CSF.
4010 15845642 We also show that BCG causes the impairment of IL-12 and the induction of IL-10 secretion by DC, irrespective of DC-SIGN expression.
4011 15855014 Here, we evaluated innate and adaptive immune system cytokine responses induced by HPV-16 L1 VLP in whole blood (WB) cultures from individuals receiving the vaccine (n=20) or placebo (n=4) before and after vaccination. 11 cytokines were measured: IL-1beta, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IFN-gamma, TNF-alpha, and GM-CSF using multiplex bead arrays.
4012 15867395 Increased NK activity was associated with a raise in CD3-CD56+ NK and/or CD3+CD56+ NK-like T cells, displaying enhanced expression of NKG2D and/or NKp46 receptors.
4013 15867395 Up-regulated expression of CD83 and CD40 and increased interleukin-12 release on stimulation were observed in CD14+ cells from post-HSP96 peripheral blood mononuclear cells, suggesting an indirect pathway of NK stimulation by HSP96-activated monocytes.
4014 15877606 Monocyte-derived dendritic cells (mDC), the most frequently applied DC subset in clinical studies, which can be obtained easily from peripheral blood monocytes after incubation with GM-CSF and IL-4, have not been clearly demonstrated to be activated by CpG oligodeoxynucleotides (ODN).
4015 15877606 However, we did not observe increased expression of maturation-associated and functionally relevant surface antigens (CD14, HLA-DR, CD40, CD83, CD80 and CD86), significant secretion of IL-12 and IFN-alpha in culture supernatant, or enhanced antitumour activation of cytokine-induced killer cells.
4016 15885128 Analysis of the cytokine profiles of draining lymph nodes or lymph-node-derived mononuclear cells from different groups by real-time reverse transcription-polymerase chain reaction revealed that, while gene-gun-bombardment induced a Th2-type cytokine microenvironment with increased interleukin-4 (IL-4) and IL-10 mRNA expression and almost no increase in IL-12 and interferon-gamma mRNA expression in draining lymph nodes, intradermal injection as well as subcutaneous injection of muscle induced the opposite.
4017 15892621 A complete prevention was obtained using a combination of three signals (the so called "triplex" vaccine) that included the specific antigen (p185, the product of HER-2/neu) and nonspecific signals like allogeneic histocompatibility antigens and interleukin 12.

4050 15905497 In addition to CD45RA(high) plasmacytoid DC, two distinct CD24(high) and CD11b(high) cDC subsets were present, and these subsets showed equivalent properties to splenic CD8(+) and CD8(-) cDC, respectively, in the following: 1) surface expression of CD11b, CD24, and signal regulatory protein-alpha; 2) developmental dependence on, and mRNA expression of, IFN regulatory factor-8; 3) mRNA expression of TLRs and chemokine receptors; 4) production of IL-12 p40/70, IFN-alpha, MIP-1alpha, and RANTES in response to TLR ligands; 5) expression of cystatin C; and 6) cross-presentation of exogenous Ag to CD8 T cells.

4056 15905564 Interestingly, both STAT4(-/-) and STAT6(-/-) mice failed to reject IL-4-transfected tumors in concert with the reduced capacity of TIDCs to produce IL-12p70 and to promote specific antitumor CTL reactivity.

4060 15936827 Interleukin-12 (IL-12) is a key component in driving the development of cell-mediated immunity as well as stimulating interferon-gamma (IFN-gamma) production from T cells and natural killer cells.
4061 15936827 Finally, in response to viral antigen recall challenge, PAMs isolated from rpIL-12-treated/PRRSV-infected animals produced greater amounts of IFN-gamma and lesser amounts of interleukin-10 than PAMs isolated from non-rpIL-12-treated/PRRSV-infected animals.
4062 15944274 Exposure of a LC-like cell line to ATPgammaS in the presence of LPS and GM-CSF augmented the induction of I-A, CD80, CD86, IL-1beta, and IL-12 p40 while inhibiting the expression of IL-10, suggesting that the immunostimulatory activities of purinergic agonists in the skin are mediated at least in part by P2Rs on APCs.
4063 15944302 Whereas RA reduced type 1 cytokines (IFN-gamma and IL-12), PIC enhanced both type 1 and type 2 cytokines (IL-4 and IL-12) and cytokine-related transcription factors.
4064 15944302 Despite the presence of PIC, the IL-4:IFN-gamma ratio was significantly elevated by RA.
4065 15944302 In addition, RA and/or PIC modulated NK/NKT cell populations and the level of expression of the costimulatory molecules CD80/CD86, evident 3 days after priming.
4066 15944302 Notably, the NKT:NK and CD80:CD86 ratios were correlated with the IL-4:IFN-gamma ratio, indicative of multiple converging modes of regulation.
4067 15955282 The aim of this study was to determine the immunomodulatory effects of IL-12, IL-18 and CD154 (CD40 ligand, CD40L) in DNA-vaccination against the classical swine fever virus.
4068 15955282 Four recombinant plasmids were constructed including the CSFV coding region for the glycoprotein gp55/E2 alone or together with porcine IL-12, IL-18 or CD154 genes.
4069 15955282 This study showed that co-delivery of IL-18 and CD154 induced an earlier appearance of serum antibodies, reduced B-cell deficiency after infection and protected pigs against a lethal CSFV infection.

4073 15972497 Our results showed that StxB1 and mStx1, but not native Stx1 (nStx1), resulted in enhanced expression of CD86, CD40, and major histocompatibility complex (MHC) class II molecules and, to some extent, also enhanced the expression of CD80 on bone marrow-derived DCs.
4074 15972497 StxB1-treated DCs exhibited an increase in tumor necrosis factor alpha and interleukin-12 (IL-12) production, a stimulation of DO11.10 T-cell proliferation, and the production of both Th1 and Th2 cytokines, including gamma interferon (IFN-gamma), IL-4, IL-5, IL-6, and IL-10.
4075 15972497 When mice were given StxB1 subcutaneously, the levels of CD80, CD86, and CD40, as well as MHC class II expression by splenic DCs, were enhanced.
4076 15972497 OVA-specific CD4+ T cells isolated from mice immunized with OVA plus mStx1 or StxB1 produced IFN-gamma, IL-4, IL-5, IL-6, and IL-10, indicating that mStx1 and StxB1 elicit both Th1- and Th2-type responses.
4077 15985227 Vaccination via intranasal and subcutaneous routes triggered immune activation in the spleen and cervical lymph node, while the former route of vaccination lead to higher antigen-specific lymphocyte proliferation, interferon-gamma, interleukin-12 and interleukin-4 responses in cervical lymph node and induction of antigen-specific IgA responses at mucosal level of the respiratory tract.
4078 16002678 Treatment of naive mice with the COX-2 inhibitor, SC-58236, skewed splenocytes toward a type 1 cytokine response, inducing IFN-gamma, IL-12, and IFN-gamma-inducible protein 10, whereas the type 2 cytokines IL-4, IL-5, and IL-10 remained unaltered.
4079 16002678 Studies performed in CD4 and CD8 knockout mice revealed a requirement for the CD4 T lymphocyte subset for the complete rejection of tumors.
4080 16002678 In vivo depletion of IFN-gamma abrogated the COX-2 inhibitor-mediated enhancement of the vaccination effect.

4115 16037410 Dendritic cells differentiated in the presence of IFN-{beta} and IL-3 are potent inducers of an antigen-specific CD8+ T cell response.
4116 16037410 Classically, mature monocyte-derived DC are generated in vitro in the presence of interleukin (IL)-4, granulocyte macrophage-colony stimulating factor, and inflammatory cytokines (G4-DC).
4117 16037410 Recently, it has been described that DC can also be generated in the presence of IL-3 and interferon (IFN)-beta and that these DC are efficiently matured using polyriboinosinic polyribocytidylic acid (I3-DC).
4118 16037410 Phenotypic characterization of the DC revealed differences in the expression of the monocyte marker CD14 and the maturation marker CD83.
4119 16037410 Low expression of CD14 and high expression of CD83 characterized G4-DC, whereas I3-DC displayed intermediate expression of CD14 and CD83.
4120 16037410 Upon CD40 ligation, G4-DC produced lower amounts of IFN-alpha and pulmonary and activation-regulated chemokine, similar amounts of IL-6, macrophage-inflammatory protein (MIP)-1alpha, and MIP-1beta, and higher amounts of IL-12 p70, tumor necrosis factor alpha, and MIP-3beta than I3-DC.

4122 16041007 Mucosal type 2/3 responses (producing interleukin-4 [IL-4], IL-6 and/or transforming growth factor beta) could be necessary for optimal induction of protective secretory immunoglobulin A responses.
4123 16041007 On the other hand, systemic type 1 responses (including gamma interferon [IFN-gamma], tumor necrosis factor alpha, and optimal cytotoxic T-cell responses) are likely to be critical for protection against the disseminated intracellular replication that occurs after mucosal invasion.

4132 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.
4133 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.
4134 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.
4135 16060834 In this study, we sought to determine whether a series of intramuscular priming immunizations with a plasmid DNA vaccine expressing SIVgag p39, in combination with plasmid expressed rhesus IL-12, could effectively enhance the immunogenicity and postchallenge efficacy of two intranasal doses of recombinant vesicular stomatitis virus (rVSV)-based vectors expressing HIV-1 env 89.6P gp160 and SIVmac239 gag p55 in rhesus macaques.
4136 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.
4137 16078831 Additionally, MDP-C increases the expression levels of several surface molecules, including CD11c, MHC class I, and intercellular adhesion molecule-1 in BMDCs.
4138 16080032 As expected, there were several strong reports on the beneficial bioactivity of cytokines, such as IL-12, GM-CSF, and IL-2.
4139 16098610 Studies in non-pregnant cattle and in murine models of infection have shown the importance of T-helper 1-type immune responses involving pro-inflammatory cytokines, such as IFNgamma and IL-12, in limiting intracellular multiplication of the parasite.
4140 16101960 After nonlethal challenge with invasive P. gingivalis W50, production of interleukin (IL)-2, IL-4, IL-5 and IL-12 was elevated; however, interferon (IFN)-gamma was lower in the serum of the DNA vaccine-immunized mice than in the serum of nonimmunized mice.
4141 16103178 The majority of adenovirus serotypes utilize the coxsackievirus-adenovirus receptor (CAR) for virus-host cell attachment, but subgroup B and subgroup D (adenovirus type 37 [Ad37]) viruses recognize CD46.

4143 16103178 A reported consequence of CD46 engagement is a reduced capability of human immune cells to express interleukin-12 (IL-12), a cytokine involved in both the innate and adaptive immune responses.
4144 16103178 Subgroup B (Ad16 and -35) and Ad37, but not Ad2 or -5, significantly reduced IL-12 production by human peripheral blood mononuclear cells stimulated with gamma interferon (IFN-gamma) and lipopolysaccharide.
4145 16103178 IL-12 mRNA (p35 and p40 subunits) levels as well as other cytokine mRNA levels (IL-1alpha and -beta, IL-1Ra, and IL-6) were decreased upon interaction with CD46-utilizing Ads.

4164 16115702 The mutant increased IL-12p40, TNFalpha and nitric oxide production by IFNgamma-stimulated bone marrow macrophages but cholera toxin did not.
4165 16115702 These findings indicate that the mutant may induce Thl-type response to the vaccine through its IL-12 and TNFalpha induction by macrophages.
4166 16125282 We have previously demonstrated that anti-HER2/neu IgG3-(IL-2), (IL-12)-IgG3, or IgG3-(GM-CSF) antibody fusion proteins (mono-AbFPs) elicit anti-tumor activity against murine tumors expressing HER2/neu when used as adjuvants of extracellular domain of HER2/neu (ECD(HER2)) protein vaccination.

4230 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).

4232 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.
4233 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).
4234 16165219 Expression of IFNgamma by several T-cell subsets correlated with reduced lung lesions and viremia, whereas expression of CD25 did not.

4242 16175400 Furthermore, many cancer patients exhibit a cytokine profile skewed toward IL10 and TGFbeta.
4243 16175400 IL12 and IFNgamma were expressed by CD40L-engineered DCs, while TNFalpha-matured DCs lacked IFNgamma and exhibited low IL12 expression.
4244 16175400 We further demonstrate that the resistance of CD40L-expressing DCs to TGFbeta and IL10 may be due to decreased levels of TGFbeta and IL10 receptors.
4245 16175400 Thus, CD40L-engineered DCs are robust Th1-promoting ones that are resistant to Tr1/Th3-signaling via IL10 and TGFbeta.
4246 16179007 Adenovirus vectors encoding carcinoembryonic antigen (Ad-CEA) or costimulatory molecules CD80, intercellular adhesion molecule-1 (ICAM-1) and leucocyte function-associated antigen-3 (LFA-3) (Ad-STIM) were used to transduce murine bone marrow-derived dendritic cells (BMDC).
4247 16179007 Transduction of cells grown in presence of heterologous serum increased the expression of costimulatory molecules, major histocompatibility complex class II, of IL-6 and IL-12.
4248 16179007 Nonetheless, CEA-specific CD8+ T-cell response was enhanced upon coinfection of Ad-STIM and Ad-CEA in both mouse strains, although this immune response was not sufficient to protect CEA-tg mice from tumour challenge.

4439 16306600 Th-cytotoxic T-lymphocyte chimeric epitopes extended by Nepsilon-palmitoyl lysines induce herpes simplex virus type 1-specific effector CD8+ Tc1 responses and protect against ocular infection.
4440 16306600 As a model antigen, the HSV-1 glycoprotein B498-505 (gB498-505) CD8+ CTL epitope was synthesized in line with the Pan DR peptide (PADRE), a universal CD4+ Th epitope.
4441 16306600 The palmitoyl-tailed Th-CTL chimeric epitopes provoked cell surface expression of major histocompatibility complex and costimulatory molecules and production of interleukin-12 and tumor necrosis factor alpha proinflammatory cytokines by immature dendritic cells.
4442 16310897 Intramuscular vaccination of foxhounds with a Leishmania multicomponent (10 antigen) DNA vaccine resulted in antigen-induced lymphoproliferative and IFN-gamma (but not IL-4) responses.
4443 16310897 This response was not augmented by co-administration of canine IL-12 or GM-CSF DNA adjuvants.
4444 16314009 We have utilised a DNA prime-BCG boost strategy in a murine M. bovis challenge model using a cocktail of 3 DNA vaccines (encoding Hsp65, Hsp70 and Apa) followed by BCG.
4445 16314009 When spleen cell cytokine production to BCG antigens was analysed, significantly more IFNgamma and IL-12 was seen in those groups primed with DNA (coding or vector) prior to BCG than those receiving BCG alone.
4446 16328003 Moderately immunogenic HPV 16-associated murine tumour cell line mimicking human HPV 16-associated neoplasms TC-1 (MHC class I(+)) and its variants, TC-1/P3C10 and TC-1/A9, with a marked down-regulation of MHC I molecules, were used to examine the effect of local interleukin 12 (IL-12) gene therapy for the treatment of early tumour transplants and minimal residual tumour disease obtained after cytoreductive chemotherapy (CMRTD).
4447 16328003 It was found that peritumoral administration of IL-12-producing tumour cell vaccines (single dose, day 8 after tumour cell administration) inhibited the growth of both TC-1 (MHC class I positive) tumours and their MHC class I-deficient variants.
4448 16328003 This treatment was followed by peritumoral s.c. administration of genetically modified TC-1 (MHC class I positive) or MK16/I/IIIABC (MHC class I negative) vaccines producing IL-12 (single dose, day 7 after chemotherapy) or with recombinant interleukin 12 (rIL-12) in two cycles of 5 daily doses (days 8-19) after chemotherapy.
4449 16328003 This combined therapy significantly inhibited the growth of TC-1 and TC-1/A9 (MHC class I-) tumours.
4450 16328003 When the combined therapy of TC-1 (MHC class I positive) tumours was followed by peritumoral administration of bone marrow dendritic cell (BMDC) vaccines, the IL-12-mediated inhibitory effect was significantly boosted.

4461 16343993 Development of cell-based tuberculosis vaccines: genetically modified dendritic cell vaccine is a much more potent activator of CD4 and CD8 T cells than peptide- or protein-loaded counterparts.
4462 16343993 AdAg85A-transduced DC vaccine (AdAg85/DC) expressed higher levels of IL-12 and was much more immunogenic than Ag85 protein-loaded (pro/DC) or CD4/CD8 T cell peptide-loaded (pep/DC) DC vaccines.
4463 16343993 Compared to pro/DC or pep/DC, AdAg85/DC elicited a remarkably higher level of ex vivo IFN-gamma production by CD4 and CD8 T cells at weeks 2, 6, and 12 postimmunization, which was coupled with higher frequencies of antigen-specific T cells.
4464 16343993 By an in vivo CD8 or CD4 T cell cytotoxicity (CTL) assay, AdAg85/DC was shown to provoke much higher and more sustained levels of CD8 and CD4 CTL activity up to 12 weeks postimmunization.
4465 16352562 To understand the role of cytokines during rotavirus infection, we assessed the kinetics of tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) (proinflammatory), IL-12 (Th1 inducer), gamma interferon (IFN-gamma) (Th1), IL-4 and IL-10 (Th2), and transforming growth factor beta (Th3) cytokine responses by enzyme-linked immunosorbent assay in serum and intestinal contents of neonatal gnotobiotic pigs and IL-12, IFN-gamma, IL-4, and IL-10 cytokine-secreting cell (CSC) responses of mononuclear cells from ileum, spleen, and blood by ELISPOT.
4466 16352562 In serum, IL-6 was significantly elevated at postinoculation day (PID) 1 in the VirHRV group and at PID 3 in both HRV groups.
4467 16352562 A significantly higher percentage of pigs had IFN-gamma and IL-10 responses in serum after VirHRV infection than after AttHRV infection or in controls.
4468 16352562 Higher protection rates may be associated with more balanced Th1- and Th2-type responses, but induction of higher earlier IFN-gamma (Th1) and proinflammatory cytokines triggered by VirHRV may also play an important role in the higher intestinal immunoglobulin A responses and protection rates induced by VirHRV.
4469 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.
4470 16367942 Peripheral blood mononuclear cells were analysed with ELISPOT analysis for number of spontaneous or antigen/mitogen stimulated IFN-gamma, IL-4, IL-10 and IL-12 secreting cells or with ELISA for concentration of spontaneous or antigen/mitogen stimulated IFN-gamma, IL-5 and IL-10.
4471 16367942 Individuals with a history of gangrenous appendicitis demonstrated ability to increased IL-10 and IFN-gamma production.
4472 16367942 The increased IFN-gamma may support the notion of gangrenous appendicitis as an uncontrolled Th1 mediated inflammatory response and increased IL-10 may speculatively indicate the involvement of cytotoxic cells in the progression to perforation.
4473 16368992 A Th2 bias in the following cytokine ratios, interleukin-4 (IL-4)/IL-12, IL-5/IL-12, IL-13/IL-12, IL-4/gamma-IFN (IFN-gamma), IL-5/IFN-gamma, and IL-13/IFN-gamma, in response to SWAP predicted a 1.4- to 2.9-month longer time to reinfection (P < 0.05) and a 27 to 55% lower intensity of reinfection (P < 0.05).
4474 16368992 Only a high IL-5/IL-10 ratio in response to Sj22.6 predicted a 3.0-month-longer time to reinfection (P = 0.03).
4475 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.
4476 16369012 Plasmid interleukin-23 (IL-23), but not plasmid IL-27, enhances the protective efficacy of a DNA vaccine against Mycobacterium tuberculosis infection.
4477 16369012 Three heterodimeric cytokines, interleukin-12 (IL-12), IL-23, and IL-27, as well as IL-18, contribute to the differentiation and expansion of naive CD4(+) T cells.
4478 16369012 In this study we compared the effects of plasmids expressing both chains of IL-12, IL-23, or IL-27 as adjuvants for DNA immunization against M. tuberculosis infection.
4479 16369012 The genes encoding p19 and p40 chains of IL-23 or EBI3 and p28 chains of IL-27 were cloned on either side of a self-cleaving peptide from the FMDV2A protein.
4480 16369012 Supernatant from p2AIL-23-transfected cells induced the release of IL-17 from activated lymphocytes, confirming the presence of bioactive IL-23.
4481 16369012 In initial experiments, M. tuberculosis infection of DCs was more potent at inducing IL-12 and IL-23 secretion than infection with the vaccine strain Mycobacterium bovis bacille Calmette-Guérin (BCG), and no significant upregulation of IL-27 was observed.
4482 16369012 Coimmunization of C57BL/6 mice with DNA expressing M. tuberculosis antigen 85B (Ag85B; DNA85B) and plasmids expressing IL-23 or IL-12 stimulated stronger Ag85B-specific T-cell proliferative and IFN-gamma responses than DNA85B alone, whereas the addition of p2AIL-27 had no effect.

4500 16369012 The genes encoding p19 and p40 chains of IL-23 or EBI3 and p28 chains of IL-27 were cloned on either side of a self-cleaving peptide from the FMDV2A protein.

4504 16376465 We constructed a glycolipid-anchored hIL-12 (GPI-hIL-12) by fusing the coding region of p35 and p40 subunits of hIL-12 with the GPI-signal sequence of CD59 at the C-terminal ends.
4505 16384666 Interferon-gamma (IFN-gamma) and interleukin-12 (IL-12) gene expression was also detected after an ex vivo-specific stimulation of mice from Groups 1 and 4.
4506 16386313 We show here that a canine IL-12 DNA, constructed by fusing the p35 and p40 subunit cDNAs with an interspacing linker, generated stable IL-12 transcripts when placed under control of a strong constitutive promoter.
4507 16386313 The protein expressed from this fused cDNA was fully functional in promoting a type 1 (IFN-gamma) and suppressing a type 2 (IL-4) cytokine response following both in vitro transfection of a canine cell line and in vivo delivery to dogs.
4508 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.
4509 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.
4510 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.
4511 16388819 Cytokines IL-2 and IL-12/IL-15 induced perforin release coupled with an IFN-gamma type-1 response.
4512 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.
4513 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.
4514 16393355 Pigs were vaccinated with the TPI DNA-plasmid alone, or in conjunction with IL-12 as pcDNA3.1-P35, pcDNA3.1-P40 plasmids via intramuscular injection.
4515 16397045 Tumor-derived cyclooxygenase-2 (COX-2) and its product, prostaglandin E2, exert strong immunoinhibitory effects that block dendritic cell function and CD4+ and CD8+ T-cell proliferation and function.
4516 16397045 Increased immunocyte trafficking was likely mediated by the generation of a Th1-type tumor microenvironment because COX-2 inhibition increased expression levels of mRNA for IFN-gamma, interleukin-12, IP-10, and MIG while lowering the expression of vascular endothelial growth factor within tumors.
4517 16413950 Anti-leishmanial immune defences are primarily dependent on the ability of the host to mount an interleukin-12 (IL-12) driven Th1 type of responses.
4518 16413950 We demonstrate that an expression plasmid encoding both p35 and p40 subunits of IL-12 when co-administered with rORFF induces a significant protection with around 82% protection in both liver and spleen.
4519 16413950 The protection correlated with increased proliferative response of splenocytes and subsequent release of Th1 cytokine IFN-gamma.

4522 16413950 The protection correlated with increased proliferative response of splenocytes and subsequent release of Th1 cytokine IFN-gamma.
4523 16415100 In vivo antibody blocking experiments revealed that CD8(+) T cells, but not CD4(+) T, NK or NKT cells, were the major effector cells mediating tumor eradication.
4524 16415100 Neither IFN-gamma(-/-) nor IL-12(-/-) mice showed impaired induction of tetramer(+) CTLs.
4525 16415100 Thus, these findings revealed that CpG-ODN-induced IFN-alpha/beta, but not IL-12 or IFN-gamma, is critical for the generation of tumor-specific CTLs in response to vaccination.
4526 16415100 In vivo antibody blocking experiments revealed that CD8(+) T cells, but not CD4(+) T, NK or NKT cells, were the major effector cells mediating tumor eradication.
4527 16415100 Neither IFN-gamma(-/-) nor IL-12(-/-) mice showed impaired induction of tetramer(+) CTLs.
4528 16415100 Thus, these findings revealed that CpG-ODN-induced IFN-alpha/beta, but not IL-12 or IFN-gamma, is critical for the generation of tumor-specific CTLs in response to vaccination.
4529 16418797 Mutations in five proteins (IFNgammaR1, IFNgammaR2, IL-12/IL-23Rbeta1, IL-12/IL-23p40 and STAT1) have been found in MSMD.
4530 16421019 In the following series of experiments, we determined whether a tumor cell vaccine that uses costimulatory signals (CD80 and IL-12) is capable of eliminating tumors within the immune-privileged anterior chamber.
4531 16424055 Inoculation of mice with L1210-MBD2 induced enhanced CTL and natural killer (NK) activity and augmented interleukin-12 and IFN-gamma production.
4532 16424055 Depletion of CD8+ T cells but not CD4+ T cells completely abrogated the antileukemia activity of MBD2.
4533 16424380 Analysis of cytokines produced by spleen and lung cells, and of antibodies measured in serum and bronchoalveolar lavage fluid, shows that the immunity induced is biased toward a type 1 response (production of IL-12, IFN-gamma, and IgG2a).
4534 16443827 C274 induced macaque CD20(+) B cells to proliferate more strongly than CD40 ligand or CpG-B ISS-ODN.
4535 16443827 Increased expression of CD40, CD80, and CD86 by B cells was apparent within 24 h of exposure to C274 and persisted for up to 1 week.
4536 16443827 C274-stimulated, B cell-enriched and peripheral blood mononuclear cell suspensions from naïve and immunodeficiency virus-infected monkeys secreted several cytokines [e.g., interleukin (IL)-3, IL-6, IL-12, interferon-alpha] and chemokines [e.g., monocyte chemoattractant protein-1/CC chemokine ligand 2 (CCL2), macrophage-inflammatory protein-1alpha/CCL3, IL-8/CXC chemokine ligand 8].
4537 16446175 Culturing in the presence of granulocyte monocyte colony stimulating factor (GM-CSF) increased the in vitro differentiation and maturation of these cells into BM-derived DCs (CD11c+ and MHC class II+).
4538 16446175 Maturation of DCs was determined by increased CD80 and CD86 expression, IL-4 and IL-12 production, reduction in phagocytic capacity and increase in the antigen presenting ability to primed or naïve T lymphocytes.
4539 16466810 Interestingly, IL-4 was not produced in the absence of IL-12 in response to infection with L. amazonensis.
4540 16474127 Our results demonstrate that, in contrast to the rwt virus, rM51R-M virus induced the maturation of myeloid DC (mDC) populations, as indicated by an increase in the surface expression of CD40, CD80, and CD86 as well as the secretion of interleukin-12 (IL-12), IL-6, and type I IFN.
4541 16474127 Our studies also indicated that the production of costimulatory molecules on mDC by rM51R-M virus was dependent on the type I IFN receptor, while maturation induced by this virus was largely independent of MyD88.
4542 16516674 Therapies under investigation include topical retinoids, fusion molecules like denileukin diftitox, pegylated interferon, interleukin-2, and interleukin-12.

4544 16517714 Using the liver metastasis model of C1300 neuroblastoma cells, we assessed the protective and therapeutic effects of fusion cells transduced with the IL-12 gene and/or the IL-18 gene.
4545 16517714 With the transduction of IL-12 and IL-18 genes into the fusion cells (fusion/IL-12/IL-18), the level of IFN-gamma increased more than five times that of other fusion groups.

4547 16517714 In particular, the mice receiving fusion/IL-12/IL-18 vaccine showed a complete protective effect and the highest therapeutic effects.
4548 16517714 The present study investigates the improved loading efficiency of fusion cells and suggests that the introduction of IL-12 and IL-18 genes can induce extremely strong protective and therapeutic effects on liver metastasis of neuroblastoma.

4607 16525645 In this study, DCs expressing the natural tumor antigen gp70 of BALB/c-derived CT26 were adenovirally transduced with the IL-12 gene and/or GM-CSF gene, and it was examined whether vaccinations using these genetically engineered DCs can induce strong therapeutic antitumor immunity.
4608 16525645 The cytotoxic activity of CTLs against CT26 in mice immunized with DCs expressing gp70 (DC-AxCAgp70) was significantly augmented by co-transduction with the GM-CSF/IL-12 gene (p<0.0001) and remarkably reduced by the depletion of CD4+ or CD8+ cells (p<0.01).

4642 16531561 Interleukin (IL)-12 secretion by PPD-stimulated PBMC was not reduced in BU patients, indicating that reduction in IFN-gamma responses was not caused by diminished IL-12 production.
4643 16543948 Yeast zymosan, a stimulus for TLR2 and dectin-1, induces regulatory antigen-presenting cells and immunological tolerance.
4644 16543948 Here, we show that zymosan, a stimulus for TLR2 and dectin-1, regulates cytokine secretion in DCs and macrophages to induce immunological tolerance.
4645 16543948 First, zymosan induces DCs to secrete abundant IL-10 but little IL-6 and IL-12(p70).
4646 16543948 Induction of IL-10 is dependent on TLR2- and dectin-1-mediated activation of ERK MAPK via a mechanism independent of the activation protein 1 (AP-1) transcription factor c-Fos.
4647 16543948 Such DCs stimulate antigen-specific CD4+ T cells poorly due to IL-10 and the lack of IL-6.
4648 16543948 Finally, coinjection of zymosan with OVA plus LPS suppresses the response to OVA via a mechanism dependent on IL-10, TGF-beta, and lack of IL-6.
4649 16543948 Together, our data demonstrate that zymosan stimulates IL-10+ IL-12(p70)- IL-6low regulatory DCs and TGF-beta+ macrophages to induce immunological tolerance.
4650 16548886 In this study we analyse the interaction of the MP from Candida albicans (MP65) with dendritic cells (DC) and demonstrate that MP65 stimulates DC and induces the release of TNF-alpha, IL-6 and the activation of IL-12 gene, with maximal value 6 h post treatment.
4651 16548886 The latter effect is partly mediated by toll-like receptor 2 (TLR2) and TLR4, and the MyD88-dependent pathway is involved in the process.
4652 16552035 Animals primed with the F. novicida DeltaiglC (KKF24) mutant induced robust splenic gamma interferon (IFN-gamma) and interleukin-12 (IL-12) recall responses with negligible IL-4 production as well as the production of antigen-specific serum immunoglobulin G1 (IgG1) and IgG2a antibodies.
4653 16552713 The hepatitis C virus (HCV) binds to human cells through the interaction of its envelope glycoprotein E2 with the tetraspanin CD81.
4654 16552713 We have previously reported that engagement of CD81 has opposite effects on T and NK cell function, as it enhances T cell receptor-mediated T cell activation and inhibits CD16- or IL-12-mediated NK cell activation.
4655 16552713 We further investigated this dichotomy and found that another tetraspanin, CD82, induces the same opposing effects on human primary T and NK cells.
4656 16552713 Activation by other unrelated stimuli such as NKG2D- and beta-1 integrin is also reduced by CD81 ligation on NK cells.
4657 16585589 During the chronic stage of the infection, the bacterial load in the lungs of immune mice remained at a level 10 times lower than control mice, and this was associated with reduced numbers of CD4P(+P) and CD8P(+P) T cells, and the lower expression of protective (IL-12, IFN-gamma), inflammatory (TNF-alpha), immunoregulatory (GM-CSF), and immunosuppressive (IL-10) cytokines.
4658 16603588 In B10.A mice, neutrophil depletion resulted in increased levels of interleukin (IL)-12 and IL-4 in the lungs, high levels of hepatic cytokines, and increased synthesis of T helper cell type 1 (Th1)- and Th2-regulated antibodies [immunoglobulin G1 (IgG1), IgA, and IgG3].
4659 16603588 In neutrophil-depleted A/J mice, high levels of pulmonary IL-12 and granulocyte macrophage-colony stimulating factor were concomitant to diminished levels of hepatic cytokines and increased amounts of Th1-regulated isotypes (IgG2a, IgG2b, and IgG3).
4660 16616574 Immunization with MIC1 and MIC4 induces protective immunity against Toxoplasma gondii.
4661 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.
4662 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.
4663 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.
4664 16620826 While susceptibility to chronic infection is propagated by T helper cell type 1 cytokine responses (characterised by production of IL-12, IL-18 and interferon-gamma), immunity to intestinal-dwelling adult nematode worms is critically dependent on a type 2 cytokine response (controlled by CD4+T helper type 2 cells that secrete the cytokines IL-4, IL-5, IL-9 and IL-13).
4665 16621179 Protective immunity in both immunoprophylaxis and immunotherapy models was associated with increased protein production of IL-12 and IFN-gamma.
4666 16632108 While no variations were seen in serum IL12 or TNFalpha levels, a high IFNgamma secretion was detected from Day 8, concomitant to IFNalpha, followed by IL10.
4667 16632108 Specific Th1 and CD8 responses were detected on Day 28, with high IFNgamma/TNFalpha ratios.
4668 16634802 The effect of M. bovis infection, 4 months post-challenge, was to suppress the expression of anti-inflammatory cytokines interleukin (IL)-4 and IL-10 as well as the pro-inflammatory cytokines tumour necrosis factor (TNF) and IL-6.
4669 16634802 Expression of interferon (IFN)-gamma and IL-12 was maintained.
4670 16634802 In particular, no decrease in expression of IL-4 or IL-6 was observed following challenge of vaccinated animals and decreased IFN-gamma was detected.
4671 16634802 Also, vaccinated animals had higher levels of IL-4 and IL-10 transcripts compared to unvaccinated animals following challenge.
4672 16634802 These changes in cytokine expression levels led to a significant shift in the IFN-gamma/IL-4 or IFN-gamma/IL-10 ratio within the lymph node following challenge.
4673 16634802 An inverse correlation between the level of pathology and bacterial load within the lymph node and the expression of IL-4, IL-10 and TNF was also observed.
4674 16642253 Regulation of innate and adaptive immune responses by the related cytokines IL-12, IL-23, and IL-27.
4675 16642253 This point is well illustrated by the IL-12/IL-23/IL-27 family, whose members share ligand and receptor subunits and play somewhat overlapping roles in innate and adaptive immune responses.

4678 16643898 We previously demonstrated that DBA/2 mice immunized in the flank with a P815 tumor cell vaccine that expressed CD80/IL-12 was unable to terminate immune privilege and prevent tumor growth in the anterior chamber.
4679 16647169 IL-12- and IL-4-deficient mice were immunized to study the individual roles of Th1 and Th2 cells, respectively.
4680 16647169 While IL-4-deficient mice developed a protective immune response similar to that found in wild-type mice, it was not possible to induce protective immunity in the highly susceptible IL-12-deficient mice due to severe disease symptoms and death following inoculation of the SE vaccine strain (doses >or=5 x 10(2)CFU were lethal for IL-12-deficient mice).

4683 16672547 Using the SIV-macaque system to advance oral vaccine research, we examined macaque PDC and MDC biology, identifying ways to activate DCs and boost antiviral immunity.
4684 16672547 Immunostimulatory oligodeoxyribonucleotides (ISS-ODNs) stimulated PDC/MDC mixtures to up-regulate co-stimulatory molecule expression and to secrete both IFN-alpha and IL-12.
4685 16672547 Additionally, ISS-ODNs augmented SIV-specific IFN-gamma responses induced by virus-bearing DCs.
4686 16691317 To analyze the immune responses caused by PEPCK, the effects of PEPCK on the induction of CD4(+) T cells and cytokines such as IFN-gamma, IL-12 and TNF-alpha were evaluated in mice.
4687 16691317 It was found that the number of CD4(+) T cells was increased in the PEPCK immunized mice although the change of the number of CD8(+) T cells was not significant.
4688 16691317 The cytokines IFN-gamma, IL-12 and TNF-alpha were increased significantly in the mice immunized with PEPCK than those of incomplete adjuvant.
4689 16691317 To analyze the immune responses caused by PEPCK, the effects of PEPCK on the induction of CD4(+) T cells and cytokines such as IFN-gamma, IL-12 and TNF-alpha were evaluated in mice.
4690 16691317 It was found that the number of CD4(+) T cells was increased in the PEPCK immunized mice although the change of the number of CD8(+) T cells was not significant.
4691 16691317 The cytokines IFN-gamma, IL-12 and TNF-alpha were increased significantly in the mice immunized with PEPCK than those of incomplete adjuvant.
4692 16701925 We administered 3000 pfu Towne CMV vaccine, with or without adjuvant recombinant interleukin-12 (rhIL-12), to CMV-seronegative healthy volunteers and then measured CMV gB-specific IgG titers and CMV-specific CD4+ and CD8+ T cell proliferation and IFNgamma expression after stimulation with whole viral lysate and immunodominant peptide CMV antigens.
4693 16701925 Adjuvant rhIL-12 at doses up to 2 microg were well-tolerated and associated with (1) dose-related increases in peak anti-CMV gB IgG titers (though not in sustained titers), (2) dose-related increases in the weak CMV viral lysate-specific CD4+ T cell proliferation responses induced by vaccine alone after 360 days of follow-up, and (3) decreases in the very robust CMV IE-specific peak CD4+ T cell and Day 360 CD8+ T cell proliferation responses induced by the vaccine alone.
4694 16701925 Also, qualitative CD8+ T cell IFNgamma responses to stimulation with the immunodominant CMV antigen, pp65, tended to occur more frequently in vaccinees who received 0.5-2.0 microg rhIL-12 compared to lower dose or no rhIL-12.
4695 16704888 The adjuvant effects of the toll-like receptor 3 ligand polyinosinic-cytidylic acid poly (I:C) on antigen-specific CD8+ T cell responses are partially dependent on NK cells with the induction of a beneficial cytokine milieu.
4696 16704888 Poly (I:C), a TLR3 ligand, has shown promise as a vaccine adjuvant to CD8(+) T cell responses.
4697 16704888 Poly (I:C) treatment was associated with a rapid induction of inflammatory cytokines in the serum, including IL-6, IL-10, MCP-1, TNF-alpha, IFN-alpha, and IFN-gamma, and selective increases in the numbers of NK (NK1.1(+)CD11b(+)) cells and Mvarphi (NK1.1(-)CD11b(+)), but not NK T (CD3(+)NK1.1(+)) cells.
4698 16704888 Poly (I:C) treatment in TNF-alpha, type I IFNR, IFN-gamma, IL-6, IL-12Rbeta2, or IL-15 gene-deficient mice revealed a reciprocal interaction and interdependence in the induction of these cytokines, where the absence of one cytokine impacted on the production of others.
4699 16704888 Further, the adjuvant effects of poly (I:C) were dependent on the endogenous levels of type I IFNs, TNF-alpha, IFN-gamma, IL-12, and IL-15.
4700 16704888 IFN-alpha and IFN-beta, but not TNF-alpha or IL-6, were able to mimic the adjuvant effects of poly (I:C).
4701 16714071 When the plasmid encoding tgB was delivered intramuscularly or epidermally by a gene gun, co-administration with IL-12 plasmid stimulated the synthesis of more IgG2a, the production of higher levels of IFN-gamma, and more effective killing by CTLs.
4702 16750567 Besides TLRs, mRNA for MyD88 and TRAF6, and nuclear translocation of NF-kappaB were enhanced that indicate their involvement in tandem in the activity of porin.
4703 16750567 The protein selectively up-regulated CD80 on the activated MPhi together with MHC class II molecule and CD40, and had no effect on CD86 expression.
4704 16750567 The porin-induced profile of MIP-1alpha, MIP-1beta and RANTES showed strong bias for chemokines correlated with M1 polarization.
4705 16750567 Intracellular expression and release of TNF-alpha and IL-12 in presence of porin was found to be TLR2 and NF-kappaB dependent.
4706 16750567 Induction of TNF-alpha and IL-12 along with the chemokine profile suggests type I polarization of the MPhi that would influence Th1-type response.
4707 16750567 Besides TLRs, mRNA for MyD88 and TRAF6, and nuclear translocation of NF-kappaB were enhanced that indicate their involvement in tandem in the activity of porin.

4718 16756175 The generation of TNF-alpha, IL-6, IL-12, and IFN-gamma was investigated in the lung homogenates in the early periods after intranasal infection of mice with A/Leningrad/134/57 (H2N2) wild-type virus and cold-adapted attenuated vaccine viruses: A/Leningrad/134/17157 (H2N2) and A/Leningrad/134/47/57 (H2N2).
4719 16756175 Wild-type virus induced substantially higher levels of proinflammatory cytokines: TNF-alpha, IL-6, IL-12, and IFN-gamma.
4720 16756175 The A/Leningrad/134/47/57 virus was marked by a noticeable production of IL-6 and IFN-gamma in the murine lung, but it was less than with wild-type virus infection.
4721 16756175 At the same time, the more attenuated strain A/Leningrad/134/47/57 induced TNF-alpha and IFN-gamma in the quantities similar to those in the control animals.
4722 16756175 The generation of TNF-alpha, IL-6, IL-12, and IFN-gamma was investigated in the lung homogenates in the early periods after intranasal infection of mice with A/Leningrad/134/57 (H2N2) wild-type virus and cold-adapted attenuated vaccine viruses: A/Leningrad/134/17157 (H2N2) and A/Leningrad/134/47/57 (H2N2).

4726 16765491 Also, treatment of murine peritoneal macrophages with the 34 kDa protein showed dose dependent increase in the production of tumor necrosis factor-alpha and interleukin-12.
4727 16775317 The NS1 protein is an important virulence factor associated with the suppression of innate immunity via the inhibition of type I interferon (IFN) production in infected cells.
4728 16775317 Among the genes affected by NS1 are those coding for macrophage inflammatory protein 1beta, interleukin-12 p35 (IL-12 p35), IL-23 p19, RANTES, IL-8, IFN-alpha/beta, and CCR7.
4729 16775317 These results indicate that the influenza A virus NS1 protein is a bifunctional viral immunosuppressor which inhibits innate immunity by preventing type I IFN release and inhibits adaptive immunity by attenuating human DC maturation and the capacity of DCs to induce T-cell responses.
4730 16778218 Interleukin-23 and interleukin-27 exert quite different antitumor and vaccine effects on poorly immunogenic melanoma.
4731 16778218 Recent studies revealed that two novel interleukin (IL)-12-related cytokines, IL-23 and IL-27, have potent antitumor activities.
4732 16778218 In this study, we investigated the antitumor efficacies of IL-23 and IL-27 on poorly immunogenic B16F10 melanoma and found that the antitumor responses mediated by IL-23 and IL-27 were clearly different.
4733 16778218 In contrast, scIL-27-transfected B16F10 (B16/IL-27) tumors exhibited significant retardation of tumor growth from the early stage.
4734 16778218 In vivo depletion assay revealed that the antitumor effect of B16/IL-23 was mainly mediated by CD8+ T cells and IFN-gamma whereas that of B16/IL-27 mainly involved natural killer cells and was independent of IFN-gamma.
4735 16778218 We also found that antitumor effects of B16/IL-23 and B16/IL-27 were synergistically enhanced by treatment with IL-18 and IL-12, respectively.
4736 16778218 Furthermore, B16/IL-23-vaccinated mice developed protective immunity against parental B16F10 tumors but B16/IL-27-vaccinated mice did not.
4737 16778218 When combined with prior in vivo depletion of CD25+ T cells, 80% of B16/IL-23-vaccinated mice completely rejected subsequent tumor challenge.
4738 16778218 Finally, we showed that the systemic administration of neither IL-23 nor IL-27 induced such intense toxicity as IL-12.
4739 16778218 Our data support that IL-23 and IL-27 might play a role in future cytokine-based immunotherapy against poorly immunogenic tumors.

4752 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).
4753 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.
4754 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.
4755 16830156 However, previous investigations have suggested that G-CSF-mobilized peripheral blood monocytes produce reduced levels of proinflammatory cytokines such as interleukin (IL)-12 and tumor necrosis factor (TNF)-alpha.
4756 16830156 In this study, we assessed the functional abilities of DCs generated from G-CSF-mobilized monocytes obtained from 13 patients with CEA-positive advanced solid cancers.
4757 16830156 Although G-CSF-mobilized monocytes (G/Mo) less effectively produced Th-1-type cytokines than control monocytes (C/Mo), DCs generated from G/Mo restored the same level of IL-12 production as that seen in DCs generated from C/Mo.
4758 16831210 Intranasal vaccination with antigen85A and antigen85B induced a significantly higher level of interferon-gamma, interleukin-12 and interleukin-4 in cervical lymph nodes together with IgA and IgG, predominantly IgG2a isotype in nasal secretion over subcutaneous vaccination.
4759 16841080 Studies of the interaction of LDC with antigen-presenting cells found that LDC triggered dendritic cell production of interleukin-12 and interferon (IFN)-gamma production by natural killer cells in vivo.
4760 16847165 The CD4+ T helper cell is critical with animal models demonstrating that cure is associated with strong IFN-gamma, interleukin (IL)-2 and IL-12 responses in the absence of classical Th2 cytokines or IL-10.
4761 16849470 IL-12p40 is induced in macrophages and dendritic cells (DC) after activation by microbial TLR ligands and cytokines and constitutes a component of IL-12 and IL-23.
4762 16857732 Critical role for serum opsonins and complement receptors CR3 (CD11b/CD18) and CR4 (CD11c/CD18) in phagocytosis of Francisella tularensis by human dendritic cells (DC): uptake of Francisella leads to activation of immature DC and intracellular survival of the bacteria.
4763 16857732 We demonstrate that complement factor C3-derived opsonins and the major complement receptors expressed by DC, the integrins CR3 (CD11b/CD18) and CR4 (CD11c/CD18), play a critical role in this adhesion-mediated phagocytosis.
4764 16857732 LVS induced proinflammatory cytokine production and up-regulation of costimulatory surface proteins (CD40, CD86, and MHC Class II) on DC but resisted killing.
4765 16857732 Serum-treated LVS rapidly induced (within 6 h) a number of cytokines including IL-10, a potent suppressor of macrophage functions and down-regulator of Th1-like responses and the Th1 response inducer IL-12.
4766 16857732 These results suggest that the simultaneous production of an activating (IL-12, IL-1beta, and TNF-alpha) and a suppressing (IL-10) cytokine profile could contribute to the immunopathogenesis of tularemia.
4767 16872726 The adjuvant RLJ-NE-299A up-regulated remarkably the expression of Th1 cytokines IL-2, IL-12, IFN-gamma, TNF alpha and Th2 cytokine IL-4 in lymph node cell cultures after 2 weeks of primary immunization with HBsAg.
4768 16889876 Important features for their efficacy include high migratory responsiveness to lymph node-chemokines and most likely their ability to produce bioactive IL-12 p70 upon subsequent contact with CD40 ligand-expressing T-cells.
4769 16889876 The current standard DC-maturation cocktail for clinical trials is inflammatory cytokines (TNF-alpha, IL-1beta and IL-6) combined with prostaglandin E(2) (PGE(2)), inducing phenotypically mature MoDCs with high migratory responsiveness to CCR7 ligands.
4770 16889876 This cocktail does not, however, induce or prime for production of IL-12 p70.
4771 16889876 Addition of IFN-gamma to PGE(2)-containing maturation cocktails has been shown to prime for substantial production of IL-12 p70 by subsequent CD40 ligation, but the impact of IFN-gamma on phenotypic maturation and migratory responsiveness induced by PGE(2)-containing inflammatory stimuli still remains elusive.
4772 16889876 Here, we demonstrate that addition of IFN-gamma to the standard maturation cocktail decreased CCR7 mRNA and down-regulated CCR7 expression on MoDCs in a dose-dependent manner.
4773 16889876 Moreover, addition of IFN-gamma was found to suppress MoDC-migration towards the CCR7-ligands CCL19 and CCL21.

4780 16893987 Regulation of lipopolysaccharide-induced interleukin-12 production by activation of repressor element GA-12 through hyperactivation of the ERK pathway.
4781 16893987 In response to LPS, peritoneal macrophages produced bioactive IL-12 p70, a heterodimer (p40/p35) of subunits, but macrophage lines such as J774.1 and RAW264.7 did not.
4782 16893987 Induction of the p35 subunit was impaired in both cell lines, and additional impairment of p40 induction was observed in RAW264.7 cells.
4783 16893987 These results suggest that some negative regulatory mechanisms against LPS-induced IL-12 p40 production are constitutively functioning in RAW264.7 cells but not in the other types of cells.
4784 16893987 Activation of GA-12 (a repressor element of IL-12 p40), rather than suppression of promoter elements, such as binding sites for NF-kappaB, AP-1, and IRF-1, was detected in LPS-stimulated RAW264.7 cells, accompanying hyperactivation of extracellular signal-related kinase (ERK).
4785 16893987 Taken together, these results demonstrate that hyperactivation of the ERK pathway plays a role in upstream signaling for the activation of GA-12, leading to the repression of IL-12 p40 production in mouse macrophages.

4808 16893987 Activation of GA-12 (a repressor element of IL-12 p40), rather than suppression of promoter elements, such as binding sites for NF-kappaB, AP-1, and IRF-1, was detected in LPS-stimulated RAW264.7 cells, accompanying hyperactivation of extracellular signal-related kinase (ERK).
4809 16893987 Taken together, these results demonstrate that hyperactivation of the ERK pathway plays a role in upstream signaling for the activation of GA-12, leading to the repression of IL-12 p40 production in mouse macrophages.
4810 16893987 Regulation of lipopolysaccharide-induced interleukin-12 production by activation of repressor element GA-12 through hyperactivation of the ERK pathway.
4811 16893987 In response to LPS, peritoneal macrophages produced bioactive IL-12 p70, a heterodimer (p40/p35) of subunits, but macrophage lines such as J774.1 and RAW264.7 did not.
4812 16893987 Induction of the p35 subunit was impaired in both cell lines, and additional impairment of p40 induction was observed in RAW264.7 cells.

4816 16899409 Lymphocyte proliferation was measured using [(3)H]thymidine uptake, and IL-12 p40 and IFN-gamma mRNA were analyzed using real-time PCR. rgpTNF-alpha alone was able to stimulate a significant degree of proliferation in splenocytes.
4817 16901590 However, only the immunization with the PFR2-HSP70 fused genes triggers in spleen cells a statistically significant enhancement of expression of IL-12 and IFN-gamma and a decrease in the percentage of cells expressing IL-4.

4826 16907922 Among the cytokines studied, interleukin (IL)-10 and IL-12 were not detected at all, whereas low levels of interferon (IFN)-gamma after 96 h (0.4 IU/ml) and tumour necrosis factor (TNF)-alpha after 48 (135 pg/ml) and 96 h (47 pg/ml) of culture were detected in the supernatants of whole blood infected with M. tuberculosis.
4827 16907922 However, the addition of monoclonal antibodies specific to TNF-alpha and IFN-gamma to the blood cultures did not alter mycobacterial growth indicating the role of other mechanisms/factors in restricting the growth of M. tuberculosis in whole blood cultures.
4828 16914349 However, the use of pCI/IL-12 as adjuvant to pCI/Sm14 immunization failed to enhance protection against challenge infection.

4882 16949577 Schistosoma mansoni infection was established using irradiated cercariae in Cercopithecus aethiops aethiops (Grivet monkey) to describe immune responses of the serum cytokines, IL-4, IL-10, IL-12, IFN- gamma, and TNF-alpha.
4883 16949577 In primary infection, IL-4 was significantly raised (p=0.03) in the immunized monkeys, and there was an insignificant increase (p>0.05) in IL-10.
4884 16949577 However, ova excretion did not influence the cytokines, except in the controls where both IL-4 and IL-10 were significantly increased (p<0.05).

4887 16960110 Purified T cells, but not NK cells, produced IFN-gamma effectively when stimulated with L. casei strain Shirota in the presence of monocytes, indicating that monocytes triggered by L. casei strain Shirota help T cells to produce IFN-gamma through secreting IL-12.

4895 16966494 This report demonstrates that the B box domain induces phenotypic maturation of murine bone marrow-derived dendritic cells (BM-DCs) as evidenced by increased CD86, CD40 and MHC-II expression.
4896 16966494 The B box domain enhanced secretion of pro-inflammatory cytokines and chemokines: IL-1beta, IL-2, IL-5, IL-8, IL-12 and tumor necrosis factor (TNF)-alpha, but not IL-6 and IL-10.
4897 16966494 Furthermore, four peptides whose sequences correspond to different regions of HMGB1 induced production of IL-1beta, IL-2 and IL-12 (p70), but not IL-10 and IL-6 in mouse BM-DCs.
4898 16966494 Interestingly, these peptides differed in their capacity to induce TNF-alpha, IL-5, IL-18 and IL-8.
4899 16971487 Here, we describe an approach to enhance immunogenicity that involves the activation of NF-kappaB by the transgenic expression of an intracellular signaling molecule, NF-kappaB-inducing kinase (NIK).
4900 16971487 In vitro, NIK increases dendritic cell antigen presentation in allogeneic and antigen-specific T cell proliferation assays by potently activating NF-kappaB and consequently up-regulating the expression of cytokines (TNF-alpha, IL-6, IL-12, IL-15, and IL-18), chemokines [IL-8, RANTES (regulated on activation, normal T cell expressed and secreted), macrophage inflammatory protein-1alpha, monocyte chemoattractant protein-1, and monocyte chemoattractant protein-3], MHC antigen-presenting molecules (class I and II), and costimulatory molecules (CD80 and CD86).
4901 16971487 In vivo, NIK enhances immune responses against a vector-encoded antigen and shifts them toward a T helper 1 immune response with increased IgG2a levels, T cell proliferation, IFN-gamma production, and cytotoxic T lymphocyte responses more potently than complete Freund's adjuvant, a very efficacious T helper 1-inducing adjuvant.
4902 16971487 These findings define NIK, and possibly other inducers of NF-kappaB activation, as a potent adjuvant strategy that offers great potential for genetic vaccine development.
4903 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.
4904 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.
4905 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.
4906 16987066 Our data indicate that 80% of the tumors expressed low levels of CD4 mRNA, with all of them expressing higher CD8 mRNA levels.
4907 16987066 Most tumors expressed interleukin (IL)-4 and IL-10 mRNAs and, most importantly, all of them expressed transforming growth factor (TGF)-beta1 and interferon gamma mRNA.
4908 16987066 None of the tumors studied expressed IL-12, IL-6, or tumor necrosis factor (TNF) mRNA.

4926 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.
4927 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.
4928 17015458 We have found that intranasal immunization with recombinant chlamydial protease-like activity factor (CPAF) induces CD4(+) T-cell- and gamma interferon (IFN-gamma)-dependent protective immunity against murine genital chlamydial infection, thus making CPAF a viable vaccine candidate for further characterization.
4929 17015458 Upon CPAF-plus-interleukin-12 (IL-12) vaccination, HLA-DR4 tg animals exhibited robust CPAF-specific IFN-gamma production and elevated titers of anti-CPAF total antibody and immunoglobulin G2a (IgG2a) and lower titers of IgG2b and IgG1 antibodies.
4930 17015458 HLA-DR4 tg and C57BL/6 mice vaccinated with CPAF plus IL-12 resolved the primary genital chlamydial infection significantly earlier than mock-immunized animals, whereas similarly vaccinated MHC class II-deficient mice displayed minimal antigen-specific immune responses and failed to resolve the infection even at 30 days postchallenge.
4931 17015458 We have found that intranasal immunization with recombinant chlamydial protease-like activity factor (CPAF) induces CD4(+) T-cell- and gamma interferon (IFN-gamma)-dependent protective immunity against murine genital chlamydial infection, thus making CPAF a viable vaccine candidate for further characterization.
4932 17015458 Upon CPAF-plus-interleukin-12 (IL-12) vaccination, HLA-DR4 tg animals exhibited robust CPAF-specific IFN-gamma production and elevated titers of anti-CPAF total antibody and immunoglobulin G2a (IgG2a) and lower titers of IgG2b and IgG1 antibodies.

4934 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.
4935 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.
4936 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.

4940 17036057 Here, we show that transfection of PGE2 matured DC with a single mRNA strain encoding for ubiquitin followed by a TAA which was linked to IL-12 by a self-cleaving 2A sequence, produced biological active IL-12p70 and were able to present the transfected TAA up to 72 h after transfection.
4941 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).
4942 17048704 IL-12 and type I interferons influence distinct steps in the adaptive immune response of lymphocytes, including the polarization of T-helper type 1 (Th1) CD4+ T cells, the development of cytolytic T cells and memory, and the antibody response.
4943 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.
4944 17055124 While the expression of Th2 type cytokine IL-10 was similar in all mice, IL-4 was not detected.
4945 17055651 Measurement of interleukine (IL) levels (IL-4, IL-5, IL-12(p40)) and interferon-gamma (IFN-gamma) in the sera of mice immunized with pBMC2 indicated high levels of IL-4 and IL-5, although there were also significant levels of IFN-gamma.
4946 17070626 Compared to unvaccinated infected chickens, vaccinated protected birds had lower expression of interleukin (IL)-6, IL-10 and IL-18 genes in spleen.
4947 17070626 However, there was no difference between these two groups of birds in the expression of interferon (IFN)-gamma, IL-4, IL-12 and inducible nitric oxide synthase (iNOS) genes on day 21 post-infection.
4948 17077176 Injection of IL-12- and IL-18-encoding plasmids ameliorates the autoimmune pathology of MRL/Mp-Tnfrsf6lpr mice: synergistic effect on autoimmune symptoms.
4949 17077176 IL-12 and IL-18 are mediators involved in the onset and progression of the autoimmune disease developing in MRL/Mp-Tnfrsf6(lpr) (lpr) mice, which display symptoms similar to the human systemic lupus erythematosus (SLE).
4950 17077176 The pathology is characterized by progressive lymphadenopathy and auto-antibody-mediated multiple organ failure, e.g. glomerulonephritis, or pneumonitis and a concomitant increase in serum levels for IFNgamma and tumor necrosis factor-alpha (TNFalpha).
4951 17077176 In this study, we intramuscularly injected lpr mice with plasmids encoding IL-12 and IL-18, either alone or in combination, in order to affect the development of the autoimmune disease.
4952 17077176 Five biweekly injections of the combined plasmids starting at 4-5 weeks of age diminished serum levels of TNFalpha and reduced the ability of lymphocytes from treated mice to produce IFNgamma in vitro.
4953 17077176 We conclude that IL-12 and IL-18 synergistically affect the pathogenesis of the T(h)1-dependent autoimmune syndrome of lpr mice and that approaches that target both IL-12 and IL-18 may be a therapeutic option in the treatment of autoimmune SLE.

4972 17079254 Ag85A, Ag85B, culture filtrate protein (CFP)-31, CFP-22.5, CFP-21, M. tuberculosis protein-64 and an as yet uncharacterised 19 kDa protein were found to be predominantly recognised by BAL cells of TB patients on the basis of lymphocyte proliferation and significant interferon-gamma release.
4973 17079254 Among polypeptides predominantly recognised by BAL lymphocytes, only Ag85A and Ag85B were found to induce both NO and interleukin-12 (p40) by alveolar macrophages.
4974 17082611 Analysis of pretherapy tumors demonstrated that advanced primary tumors were infiltrated by CD4+ and CD8+ T cells with an effector/memory phenotype and CD4+CD25+Foxp3+ T suppressor cells.
4975 17082611 Tumor-associated effector memory CD8+ T cells displayed impaired cytotoxic function, whereas CD4+CD25+Foxp3+ cells effectively inhibited T cell proliferation demonstrating functional integrity.
4976 17082611 IL-12/GM-CSF treatment promoted a rapid up-regulation of CD43 and CD69 on CD8+ effector/memory T cells, augmented their ability to produce IFN-gamma, and restored granzyme B expression.
4977 17082611 Both CD8+ T cell activation and T suppressor cell purge were mediated primarily by IL-12 and required IFN-gamma.
4978 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.
4979 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.

4982 17096339 This study was designed to determine whether the vaccination of genetically modified dendritic cells (DCs) simultaneously expressing carcinoembryonic antigen (CEA), granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin 12 (IL-12) can overcome the peripheral T-cell tolerance to CEA and thereby elicit a therapeutic response in CEA transgenic mice.
4983 17096339 The cytotoxic activity of spleen cells against CEA-expressing tumors, MC38-CEA, in the mice immunized with DCs expressing CEA (DC-AxCACEA) was higher than that in those immunized with DCs-AxCALacZ (p < 0.0001), and was augmented by the cotransduction with the GM-CSF/IL-12 gene (p < 0.05).
4984 17096339 The vaccination with DC-AxCACEA/GM-CSF/IL-12 could elicit a more potent therapeutic immunity than the vaccination with DC-AxCACEA in subcutaneous tumor models (p < 0.0001), and 4 of 5 mice showed a complete eradication of the subcutaneous tumors in these vaccination groups.
4985 17096339 This antitumor activity mostly vanished with the depletion of CD8(+) T cells and NK cells in vivo and was completely abrogated with the depletion of CD4(+) T cells.
4986 17096339 This study was designed to determine whether the vaccination of genetically modified dendritic cells (DCs) simultaneously expressing carcinoembryonic antigen (CEA), granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin 12 (IL-12) can overcome the peripheral T-cell tolerance to CEA and thereby elicit a therapeutic response in CEA transgenic mice.

4994 17106649 Flow cytometric analyses showed that TGF-beta2 does not suppress the upregulation of MHC (major histocompatibility complex) class II molecules and the T cell stimulatory capacity of human DC that were stimulated with a strong cytokine cocktail containing tumor necrosis factor alpha (TNF-alpha), IL-1beta, IL-6 and prostaglandin E2 (PGE2).
4995 17106649 Although both mature and immature DC expressed comparable amounts of the TGF-beta receptor type II, Smad2 phosphorylation and subsequent upregulation of Smad7 was inhibited in mature DC, but not immature DC.
4996 17106649 However, further analysis revealed that mature DC alone are not sufficient to mediate full T cell activation in the presence of TGF-beta2, unless IL-12 is added to the DC/T-cell coculture.
4997 17106649 Finally, we demonstrate that MHC class II expression and IL-12 secretion by DC are not disturbed by TGF-beta2 after DC stimulation with a modified maturation cocktail containing the Toll-like receptor (TLR)-ligands Poly I:C or R848, TNF-alpha, IL-1beta and INF-gamma.
4998 17114471 Ag-specific IL-17 and IFN-gamma production was significantly lower in Pw-immunized TLR4-defective mice.
4999 17114471 Stimulation of dendritic cells (DC) with Pw promoted IL-23, IL-12, IL-1beta, and TNF-alpha production, which was impaired in DC from TLR4-defective mice.
5000 17114471 B. pertussis LPS, which is present in high concentrations in Pw, induced IL-23 production by DC, which enhanced IL-17 secretion by T cells, but the induction of Th-17 cells was also dependent on IL-1.
5001 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.
5002 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.
5003 17118987 Intranasal immunization using recombinant CPAF (rCPAF) plus interleukin-12 (IL-12) (rCPAF+IL-12 immunization) was used to assess the protective immunity against genital Chlamydia muridarum infection in BALB/c mice. rCPAF+IL-12 immunization induced robust gamma interferon (IFN-gamma) production and minimal IL-4 production by splenocytes upon in vitro recall with rCPAF.
5004 17118987 This vaccination regimen also reduced the development of fibrosis and the influx of neutrophils into the upper genital tract when the animals were compared to mock-immunized (phosphate-buffered saline) animals after bacterial challenge. rCPAF+IL-12-mediated resolution of the bacterial infection and protection against Chlamydia-induced inflammatory disease were highly dependent on endogenous IFN-gamma production.

5009 17120032 Blood samples from five patients and healthy controls were in vitro activated with BCG, BCG + IL-12 and BCG + IFN-gamma and levels of IL-12p40 and IFN-gamma were measured.

5023 17142751 We have shown that the CpG-C ISS-ODN C274 stimulates macaque blood dendritic cells (DCs) and B cells and augments SIV-specific IFN-gamma responses in vitro.
5024 17142751 This was particularly apparent at the level of CD80 (less so CD86) expression by CD123(+) plasmacytoid DCs and was further boosted in the presence of additional C274 in vitro.
5025 17142751 This was more pronounced when cells were exposed to additional stimuli in vitro, producing IFN-alpha, IL-3, IL-6, IL-12, TNF-alpha, CCL2, CCL3, CCL5, and CXCL8.
5026 17142751 Elevated IFN-alpha, CCL2, and CCL5 were also detected in the plasma after C274 injection.
5027 17142769 Interleukin-23 restores immunity to Mycobacterium tuberculosis infection in IL-12p40-deficient mice and is not required for the development of IL-17-secreting T cell responses.
5028 17142769 Host control of Mycobacterium tuberculosis is dependent on the activation of CD4+ T cells secreting IFN-gamma and their recruitment to the site of infection.
5029 17142769 Cytokines important for the development of cell-mediated immunity include IL-12 and IL-23, which share the p40 subunit and the IL-12Rbeta1 signaling chain.
5030 17142769 To explore the differential effect of IL-12 and IL-23 during M. tuberculosis infection, we used plasmids expressing IL-23 (p2AIL-23) or IL-12 (p2AIL-12) alone in dendritic cells or macrophages from IL-12p40(-/-) mice.
5031 17142769 In the absence of the IL-12/IL-23 axis, immunization with a DNA vaccine expressing the M. tuberculosis Ag85B induced a limited Ag-specific T cell response and no control of M. tuberculosis infection.
5032 17142769 This response resulted in partial protection against aerosol M. tuberculosis; however, the protective effect was less than in wild-type mice owing to the requirement for IL-12 or IL-23 for the optimal expansion of IFN-gamma-secreting T cells.
5033 17142769 Interestingly, bacillus Calmette-Guérin immune T cells generated in the absence of IL-12 or IL-23 were deficient in IFN-gamma production, but exhibited a robust IL-17 secretion associated with a degree of protection against pulmonary infection.
5034 17142769 Therefore, exogenous IL-23 can complement IL-12 deficiency for the initial expansion of Ag-specific T cells and is not essential for the development of potentially protective IL-17-secreting T cells.

5075 17178781 Here we report that natural killer cells from the livers of naïve uninfected mice produced IFN-gamma when challenged with live bacteria in vitro and that the responses were greatly increased by coactivation of the cells with either recombinant interleukin-12 (IL-12) or IL-18.

5308 17240920 More recently, we evaluated the HSP 65 + hIL-12/HVJ vaccine in the cynomolgus monkey model, which is currently the best non-human primate animal model of human tuberculosis.
5309 17240920 In this particular experiment, monkeys vaccinated with HSP 65 + hIL-12/HVJ induced HSP 65-specific T-cell proliferation and improvement of chest X-P findings, resulting in an increased survival for over a year, superior to BCG group.
5310 17240920 We have developed two novel tuberculosis (TB) vaccines; a DNA vaccine combination expressing mycobacterial heat shock protein 65 (HSP 65) and interleukin-12 (IL-12) by using the hemagglutinating virus of Japan (HVJ)-liposome (HSP 65 + IL-12/HVJ).
5311 17240920 A mouse IL-12 expression vector (mIL-12 DNA) encoding single-chain IL-12 proteins comorised of p40 and p35 subunits were constructed.
5312 17240920 In a mouse model, a single gene gun vaccination with the combination of HSP 65 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.
5313 17240920 To explore the clinical use of the DNA vaccines, we evaluated HVJ-liposome encapsulated HAP 65 DNA and mIL-12 DNA (HSP 65 + mIL-12/ HVJ).
5314 17240920 HSP 65 + IL-12/HVJ vaccine induced CD8+cytoxic T lymphocyte activity against HSP 65 antigen.
5315 17240920 Protective efficacy of this vaccine was associated with the emergence of IFN-gamma-secreting T cells and activation of proliferative T cells as well as CTL induction upon stimulation with the HSP 65 and antigens from M. tuberculosis.
5316 17240920 Furthermore, we extended our studies to a cynomolgus monkey model, which is currently the best animal model of human tuberculosis, to evaluate the HSP 65 + IL-12/HVJ vaccine.
5317 17240920 Vaccination with HSP 65 + IL-12/HVJ provided better protective efficacy as assessed by the Erythrocyte Sedimentation Rate, chest X-ray findings, and immune responses than BCG.
5318 17240920 Most importantly, HSP 65 + IL-12/HVJ resulted in an increased survival for over a year.
5319 17240920 Genes (HSP 65 gene, IL-12 gene as well as Ag 85A-, 85B-, MPB51-gene) and IL-6 related genes (IL-6 gene + IL-6R gene +gp130 gene) were administered into the Balb/c mice infected (i.v. or intra-tracheal injection) with Mycobacterium tuberculosis (M. tuberculosis).
5320 17240920 HSP 65 gene + IL-12 gene vaccination, or recombinant BCG (BA51 : Antigen 85B(-) + Antigen 85A(-) + MPB51-gene recombinant BCG) were more prophylactically efficient than parental BCG Tokyo vaccination.
5321 17240920 In conclusion, we demonstrate the development of a novel HVJ-liposome DNA vaccine encapsulating HSP 65 DNA plus IL-12 DNA.
5322 17240920 These results suggest that HSP 65 + IL-12/HVJ could be a promising candidate for a new tuberculosis DNA vaccine, which is superior to the currently available BCG vaccine.
5323 17240920 More recently, we evaluated the HSP 65 + hIL-12/HVJ vaccine in the cynomolgus monkey model, which is currently the best non-human primate animal model of human tuberculosis.

5328 17255244 Parental dengue viruses induced a similar array of cytokines, but more TNF-alpha, less IL-6, and less MCP-1/CCL-2 than induced by CYD.
5329 17277122 Human immature dendritic cells (DCs) cultured in the presence of c-di-GMP showed increased expression of costimulatory molecules CD80/CD86 and maturation marker CD83, increased MHC class II and cytokines and chemokines such as IL-12, IFN-gamma, IL-8, MCP-1, IFN-gamma-inducible protein 10, and RANTES, and altered expression of chemokine receptors including CCR1, CCR7, and CXCR4. c-di-GMP-matured DCs demonstrated enhanced T cell stimulatory activity. c-di-GMP activated p38 MAPK in human DCs and ERK phosphorylation in human macrophages. c-di-GMP is stable in human serum.

5340 17293384 Before surgical resection, HER-2/neu(pos) DCIS patients (n = 13) received 4 weekly vaccinations of dendritic cells pulsed with HER-2/neu HLA class I and II peptides.
5341 17293384 Before vaccination, many subjects possessed HER-2/neu-HLA-A2 tetramer-staining CD8(pos) T cells that expressed low levels of CD28 and high levels of the inhibitory B7 ligand CTLA-4, but this ratio inverted after vaccination.
5342 17293384 The vaccinated subjects also showed high rates of peptide-specific sensitization for both IFN-gamma-secreting CD4(pos) (85%) and CD8(pos) (80%) T cells, with recognition of antigenically relevant breast cancer lines, accumulation of T and B lymphocytes in the breast, and induction of complement-dependent, tumor-lytic antibodies.
5343 17306360 These should be directed at the level of gene selection and delivery, in order to identify the optimal cytokine and achieve efficient and durable cytokine expression, and at the level of improving immune stimulation, i.e. by co-administration of co-stimulatory molecules including B7 and CD40, or boosting the expression of tumor antigens or MHC class I molecules.
5344 17306360 Interestingly, some of the cytokines which have shown encouraging anti-tumor activity, including IFNs, IL-4, IL-12 and TNF-alpha, are endowed with anti-angiogenic or vasculotoxic effects, which may significantly contribute to local tumor control.

5390 17438065 A subset of dendritic cells induces CD4+ T cells to produce IFN-gamma by an IL-12-independent but CD70-dependent mechanism in vivo.
5391 17438065 Interferon (IFN)-gamma, a cytokine critical for resistance to infection and tumors, is produced by CD4(+) helper T lymphocytes after stimulation by cultured dendritic cells (DCs) that secrete a cofactor, interleukin (IL)-12.
5392 17438065 We have identified a major IL-12-independent pathway whereby DCs induce IFN-gamma-secreting T helper (Th)1 CD4(+) T cells in vivo.
5393 17438065 This pathway requires the membrane-associated tumor necrosis family member CD70 and was identified by targeting the LACK antigen from Leishmania major within an antibody to CD205 (DEC-205), an uptake receptor on a subset of DCs.
5394 17438065 Another major DC subset, targeted with 33D1 anti-DCIR2 antibody, also induced IFN-gamma in vivo but required IL-12, not CD70.
5395 17438065 Isolated CD205(+) DCs expressed cell surface CD70 when presenting antigen to T cell receptor transgenic T cells, and this distinction was independent of maturation stimuli.
5396 17438065 CD70 was also essential for CD205(+) DC function in vivo.
5397 17438065 This in situ analysis points to CD70 as a decision maker for Th1 differentiation by CD205(+) DCs, even in Th2-prone BALB/c animals and potentially in vaccine design.

5402 17473921 Vaccination of C57BL/6 tumor-bearing mice with the TbetaRIIDN DC vaccine induced potent tumor-specific cytotoxic T lymphocyte responses against TRAMP-C2 tumors, increased serum IFN-gamma and IL-12 level, inhibited tumor growth and increased mouse survival.
5403 17485453 In the absence of CD154, administration of interleukin-12 restores Th1 responses but not protective immunity to Schistosoma mansoni.
5404 17485453 Here we demonstrate the importance of CD40/CD154 in vaccine-induced immunity, as CD154(-/-) mice exposed to RA schistosomes develop no protection to challenge infection.

5431 17576158 Higher doses of lentivirus, however, resulted in upregulation of adhesion, costimulatory, and HLA molecules, as well as in increased allostimulatory capacity and secretion of interleukin (IL)-6, IL-8, and tumor necrosis factor-alpha.
5432 17576158 Production of IL-12 p70, IL-10, and interferon-alpha was observed only at extremely high doses.
5433 17576158 A Toll-like receptor (TLR)-driven luciferase reporter assay showed dose-dependent activation of TLR2, TLR3, and TLR8, which was independent of the pseudotype, production, or transduction protocol and was abrogated on heat inactivation.
5434 17583394 In addition, serum levels of IL-12 p70 increased and ongoing OVA-specific IgE immune response was dramatically attenuated.
5435 17587500 The production of IL-12 and IFN-gamma, for example, resulting from exposure to many bacterial, viral, and protozoan pathogens is responsible for Th1-derived protective responses that also can inhibit development of Th2-cells expressing IL-4-dependent immunity to extracellular helminth parasites and vice versa.
5436 17595664 Immunotherapy for neuroblastoma using syngeneic fibroblasts transfected with IL-2 and IL-12.
5437 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.
5438 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.

5445 17599092 Each gene encoded a cell surface chimeric protein made up of extracellular single-chain immunoglobulin anti-erbB2 linked to an intracellular TLR-signaling component composed of either myeloid differentiation factor 88, interleukin-1 receptor-associated kinase-1 (IRAK-1) or the cytoplasmic domain of TLR4.
5446 17599092 However, only the chimera containing IRAK-1 was able to mediate interleukin-12 and tumor necrosis factor-alpha secretion.
5447 17599092 We found that JAWS II cells triggered through chimeric anti-erbB2-IRAK-1 displayed an enhanced ability to stimulate ovalbumin-specific OT-II CD4(+) T cells.
5448 17616633 The CSU-F36 fusion protein strongly induced interleukin 12 secretion from macrophages and induced the increased accumulation of CD4 T cells capable of secreting gamma interferon in the lungs of infected mice.
5449 17629370 In contrast, the absence of endogenous IL-12/IL-23 or IL-4 had little impact on the magnitude of the antibody response but instead caused a dramatic change in the pattern of IgG isotypes.
5450 17629370 IFN-gamma was produced by NK, dendritic cells, CD4+ and CD8+ T cells stimulated in vitro with CpG ODN.
5451 17629370 Adoptive transfer experiments confirmed that CD4+ or CD8+ T cells were in fact relevant sources of IFN-gamma in vivo.
5452 17629370 Following CpG ODN injection, splenic dendritic cells from IFN-gamma deficient mice did not up-regulate CD86 or CD40 expression, suggesting a role for these molecules.
5453 17629370 The importance of CD28 (CD86 ligand) was confirmed using CD28 deficient mice which presented severely impaired immune responses following CpG ODN-assisted immunization.
5454 17643559 Peripheral blood mononuclear cell cultures from both groups showed CD4(+), CD8(+) and remarkable gammadelta(+) T cell BCG-specific proliferation, without significant differences.
5455 17643559 Also, IL-10, IL-12, IFN-gamma and TNF-alpha concentrations in culture supernatants, measured by ELISA, were similar.
5456 17655984 Production of both IFN-gamma and IL-4 with a dominance of Th1 response following immunization was required for optimum success against L. donovani infection in BALB/c mice.
5457 17655984 The success of immunotherapy exhibited an immune modulation with surge in Th1 cytokines, IFN-gamma and IL-12 with extreme down regulation of disease promoting IL-4 and IL-10.
5458 17699845 By promoting IFN-gamma production, proliferation, and cytolytic activity of natural killer and T cells, IL-12 induces cellular immunity.
5459 17699845 In addition, IL-12 induces an antiangiogenic program mediated by IFN-gamma-inducible genes and by lymphocyte-endothelial cell cross-talk.
5460 17699845 More effective application of this cytokine, and of newly identified IL-12 family members (IL-23 and IL-27), should be evaluated as therapeutic agents with considerable potential in cancer patients.
5461 17699845 By promoting IFN-gamma production, proliferation, and cytolytic activity of natural killer and T cells, IL-12 induces cellular immunity.

5464 17699845 By promoting IFN-gamma production, proliferation, and cytolytic activity of natural killer and T cells, IL-12 induces cellular immunity.
5465 17699845 In addition, IL-12 induces an antiangiogenic program mediated by IFN-gamma-inducible genes and by lymphocyte-endothelial cell cross-talk.
5466 17699845 More effective application of this cytokine, and of newly identified IL-12 family members (IL-23 and IL-27), should be evaluated as therapeutic agents with considerable potential in cancer patients.
5467 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.
5468 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.
5469 17714025 In this review, the authors discuss a number of novel biological response modifiers that work as general stimulants of the immune system, through varied mechanisms including induction of stimulatory cytokines (such as IFN-alpha, TNF-alpha and IL-12) and activation of T cells and the antigen-presenting dendritic cells.
5470 17765973 We observed that KLH promotes the activation and maturation of DCs, as assessed by up-regulation of the surface expression of CD80, CD86, CD40, HLA-DR and CD83.
5471 17765973 Moreover, even if KLH stimulated the production of IL-12 and IL-10 by DCs, the final balance was clearly in favour of IL-12.
5472 17804754 This complex is chaperoned by heat shock protein Gp96, which mediates ISMMC uptake by antigen-presenting cells through the scavenger receptor CD91.
5473 17804754 RNAs in ISMMC stimulate immature dendritic cells to secrete interleukin 12 and induce IFN-gamma in peripheral blood mononuclear cells.
5474 17804754 On a total protein basis, Taxol induced ISMMC, expanded more CD8(+) cells, activated more CD56(+) NKG2D(+) cells to produce IFN-gamma, and were more potent inducers of high T-cell receptor density Perforin(+) cells than native ISMMC and peptide E75.
5475 17875635 Interleukin-12 (IL-12) and IL-18 are both central to the induction of gamma interferon (IFN-gamma), and various roles for IL-12 and IL-18 in control of intracellular microbial infections have been demonstrated.
5476 17875635 We used IL-12p40(-/-) and IL-18(-/-) mice to further investigate the role of IL-12 and IL-18 in control of Salmonella enterica serovar Typhimurium.
5477 17875635 In addition, we demonstrated by flow cytometry that equivalent or increased numbers of T cells produced IFN-gamma in IL-12p40(-/-) mice compared with the numbers of T cells that produced IFN-gamma in C57BL/6 and IL-18(-/-) mice.
5478 17875635 Our results suggest that IL-12p40, but not IL-18, is critical to resolution of infections with attenuated S. enterica serovar Typhimurium and that especially the effects of IL-12p40 on proliferative responses of CD4+ T cells, but not the ability of these cells to produce IFN-gamma, are important in the resolution of infection by this intracellular bacterial pathogen.
5479 17875635 Interleukin-12 (IL-12) and IL-18 are both central to the induction of gamma interferon (IFN-gamma), and various roles for IL-12 and IL-18 in control of intracellular microbial infections have been demonstrated.
5480 17875635 We used IL-12p40(-/-) and IL-18(-/-) mice to further investigate the role of IL-12 and IL-18 in control of Salmonella enterica serovar Typhimurium.
5481 17875635 In addition, we demonstrated by flow cytometry that equivalent or increased numbers of T cells produced IFN-gamma in IL-12p40(-/-) mice compared with the numbers of T cells that produced IFN-gamma in C57BL/6 and IL-18(-/-) mice.
5482 17875635 Our results suggest that IL-12p40, but not IL-18, is critical to resolution of infections with attenuated S. enterica serovar Typhimurium and that especially the effects of IL-12p40 on proliferative responses of CD4+ T cells, but not the ability of these cells to produce IFN-gamma, are important in the resolution of infection by this intracellular bacterial pathogen.
5483 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.
5484 17929411 In the study, concentrations of IFN-gamma/Il-2 and 1l-4/Il-5 in supernatants of cultured mice splenocytes have been determined to evaluate differences in Th1 or Th2 lymphocytes subpopulation response.
5485 17929411 Simultaneously, studies of intracellular expression of genes encoding of Il-2, Il-12, IFN-gamma and Il-4, Il-5, Il-10, Il-13 in mice splenocytes, and genes encoding factors involved in inflammatory process in the lung tissue (GM-CSF, TNF-alpha, Il-1beta, Il-6 i TGF-beta) have been performed on RNA level.
5486 17942608 Immunization with rCPAF plus IL-12 (rCPAF+IL-12), compared to immunization with rIncA+IL-12 or rMOMP+IL-12, induced the greatest antigen-specific gamma interferon production from purified CD4(+) T cells and concurrently enhanced serum antibody production.
5487 17942935 We show that in contrast to effector CD8+ T cells that kill antigen-carrying dendritic cells, IFNgamma-producing memory CD8+ T cells act as "helper" cells, supporting the ability of dendritic cells to produce interleukin-12 (IL-12) p70.
5488 17944743 Both IFN-gamma and IL-12 play critical roles in defence against malaria.
5489 17944743 In a previous study, using Plasmodium yoelii model, C57BL/6 IFN-gamma receptor deficient mice (IFN-gammaR-/-) failed to develop protective immunity after a single immunization with irradiated sporozoites, but were protected after multiple immunizations.
5490 17944743 Protection was partially and largely mediated by CD4+ T cells and CD8+ T cells, respectively.
5491 17961769 Single TLR ligands induced maturation only in adult DC; neonatal DC matured with combined targeting of TLR3/TLR8 or TLR4/TLR8, based on the expression of maturation markers.
5492 17961769 Moreover, this interferon-gamma secretion was blocked by anti-IL-12p70 antibodies and increased after addition of recombined IL-12.
5493 17978011 We used a multiplex, suspension-array-based immunoassay method to measure 10 proinflammatory (interleukin-1beta [IL-1beta], IL-6, and IL-8) and immunoregulatory (gamma interferon [IFN-gamma], IL-2, IL-4, IL-5, IL-10, IL-12, and IL-13) cytokines in cervical mucus specimens collected via ophthalmic sponge from 72 healthy, nonpregnant women and correlate their levels with biologic and behavioral covariates in a cross-sectional design.
5494 17978011 Among the covariates examined, the most striking finding was the significant (P < or = 0.05) association between depressed levels of the cytokines IFN-gamma, IL-1beta, IL-6, and IL-10 and cigarette smoking.
5495 17991045 We show here that exposure of human DC to live meningococci does not result in a typical maturation response, as determined by the failure to upregulate CD40, CD86, HLA-DR and HLA-Class I.
5496 17991045 Despite this, live meningococci were potent inducers of IL-12 and IL-10, although the ratios of these cytokines differed from those to killed organisms.
5497 18006123 Expression of lymphotactin mRNA was higher in R(low)-inoculated chickens than GT5- or PBS-inoculated chickens, while CXCL13/BCA1 mRNA expression level was higher in both GT5- or R(low)-inoculated chickens than in PBS-inoculated controls on day 1 post-inoculation.
5498 18006123 However, both R(low) and GT5 strains induced a down-regulation in mRNA expression of CCL20, IL-1beta, IL-8 and IL-12p40 genes, with CCL20 and IL-12 mRNA levels remaining lower on days 4 and 8 post-inoculation.
5499 18006123 On day 4, R(low)-inoculated chickens exhibited significantly higher tracheal lesion scores and higher levels of lymphotactin, CXCL13, CXCL14, RANTES, MIP-1beta, IL-1beta and IFN-gamma mRNA compared to PBS-inoculated controls.
5500 18006123 Our data also suggest that M. gallisepticum may modulate the host response causing dramatic decreases in CCL20, IL-8 and IL-12 mRNA levels in GT5- or R(low)-inoculated chickens as early as one day post-inoculation.
5501 18006123 Expression of lymphotactin mRNA was higher in R(low)-inoculated chickens than GT5- or PBS-inoculated chickens, while CXCL13/BCA1 mRNA expression level was higher in both GT5- or R(low)-inoculated chickens than in PBS-inoculated controls on day 1 post-inoculation.
5502 18006123 However, both R(low) and GT5 strains induced a down-regulation in mRNA expression of CCL20, IL-1beta, IL-8 and IL-12p40 genes, with CCL20 and IL-12 mRNA levels remaining lower on days 4 and 8 post-inoculation.
5503 18006123 On day 4, R(low)-inoculated chickens exhibited significantly higher tracheal lesion scores and higher levels of lymphotactin, CXCL13, CXCL14, RANTES, MIP-1beta, IL-1beta and IFN-gamma mRNA compared to PBS-inoculated controls.
5504 18006123 Our data also suggest that M. gallisepticum may modulate the host response causing dramatic decreases in CCL20, IL-8 and IL-12 mRNA levels in GT5- or R(low)-inoculated chickens as early as one day post-inoculation.
5505 18018602 Furthermore, 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).
5506 18019188 Correlates of protection involve robust CD4+ and CD8+ T cell responses, and the production of IFN-gamma, TNF-alpha, and IL-12.
5507 18025169 We have previously shown that rSbsC-Bet v 1, the recombinant fusion protein of a bacterial surface (S-layer) protein of Geobacillus stearothermophilus ATCC 12980 and the major birch pollen allergen Bet v 1, exhibited reduced allergenicity and induced IFN-gamma and IL-10 synthesis in Bet v 1-specific Th2 clones.
5508 18025169 In this study, we characterized the effects of rSbsC-Bet v 1 on immature monocyte-derived dendritic cells (mdDC) and the consequences for the polarization of naive CD4(+) T lymphocytes isolated from the blood of birch pollen-allergic patients. mdDC responded to rSbsC-Bet v 1 with a significant up-regulation of costimulatory molecules, functional maturation, and the synthesis of IL-10 and IL-12. mdDC matured with rSbsC-Bet v 1 induced the differentiation of naive T cells into IFN-gamma-producing cells.
5509 18025169 In parallel, a substantial number of naive T cells developed into IL-10-producing CD25(+)Foxp3(+)CLTA-4(+) cells capable of active suppression.
5510 18025215 Similar to levels induced by bacterial cells, MV-stimulated macrophages and dendritic cells displayed increased surface expression of MHC-II and CD86 and enhanced production of the proinflammatory mediators NO, TNF-alpha, and IL-12.
5511 18025217 Differential requirements by CD4+ and CD8+ T cells for soluble and membrane TNF in control of Francisella tularensis live vaccine strain intramacrophage growth.
5512 18025217 Generation of CD44(high) memory T cells and clearance of bacteria were similar, although more IFN-gamma and IL-12(p40) were produced by memTNF mice.
5513 18025217 LVS-immune CD4(+) and CD8(+) T cells isolated from WT and memTNF mice exhibited comparable control of LVS growth in either normal or TNF-alpha knockout macrophages.
5514 18025217 Although the magnitude of CD4(+) T cell-induced macrophage NO production clearly depended on TNF, control of LVS growth by both CD4(+) and CD8(+) T cells did not correlate with levels of nitrite.
5515 18025217 Importantly, intramacrophage LVS growth control by CD8(+) T cells, but not CD4(+) T cells, was almost entirely dependent on T cell-expressed TNF, and required stimulation through macrophage TNFRs.
5516 18033300 Here we demonstrate that Epstein-Barr-virus-induced gene 3 (Ebi3, which encodes IL-27beta) and interleukin-12 alpha (Il12a, which encodes IL-12alpha/p35) are highly expressed by mouse Foxp3+ (forkhead box P3) T(reg) cells but not by resting or activated effector CD4+ T (T(eff)) cells, and that an Ebi3-IL-12alpha heterodimer is constitutively secreted by T(reg) but not T(eff) cells.
5517 18033300 Both Ebi3 and Il12a messenger RNA are markedly upregulated in T(reg) cells co-cultured with T(eff) cells, thereby boosting Ebi3 and IL-12alpha production in trans.
5518 18033300 T(reg)-cell restriction of this cytokine occurs because Ebi3 is a downstream target of Foxp3, a transcription factor that is required for T(reg)-cell development and function.
5519 18033300 Here we demonstrate that Epstein-Barr-virus-induced gene 3 (Ebi3, which encodes IL-27beta) and interleukin-12 alpha (Il12a, which encodes IL-12alpha/p35) are highly expressed by mouse Foxp3+ (forkhead box P3) T(reg) cells but not by resting or activated effector CD4+ T (T(eff)) cells, and that an Ebi3-IL-12alpha heterodimer is constitutively secreted by T(reg) but not T(eff) cells.
5520 18033300 Both Ebi3 and Il12a messenger RNA are markedly upregulated in T(reg) cells co-cultured with T(eff) cells, thereby boosting Ebi3 and IL-12alpha production in trans.
5521 18033300 T(reg)-cell restriction of this cytokine occurs because Ebi3 is a downstream target of Foxp3, a transcription factor that is required for T(reg)-cell development and function.
5522 18040852 The splenocytes from protected mice and morphine low concentration-treated infected-PM, elaborated significantly (p < 0.05) enhanced levels of interleukin-12, interferon-gamma, tumor necrosis factor-alpha, granulocyte-macrophage colony-stimulating factor and nitrite in the culture medium; a high dose/concentration suppressed their elaboration.
5523 18040852 Curiously, only morphine high dose/concentration-treated infected mice splenocytes and infected PM, produced significantly (p < 0.05) increased quantity of transforming growth factor-beta1.
5524 18156414 However, production of cytokines, interferon-gamma, interleukin-12, and tumor necrosis factor alpha, was numerically increased in spleen cell cultures stimulated with mitogens from FOS:inulin-fed mice 1 and 4 wk postimmunization.
5525 18165707 With regard to the cellular response, ScLL 50 and 100 microgram/animal stimulated the delayed-type hypersensitivity (DTH) reaction significantly (P < 0.05) higher than SLA or SLA plus ScLL 10 weeks after the challenge infection.
5526 18165707 The detection of high levels of IgG2a and the expression of mRNA cytokines, such as IFN-gamma, IL-12, and TNF-alpha (Th1 profiles), corroborated the protective role of this lectin against cutaneous leishmaniasis.
5527 18191311 High titers of IgG1 and IgG2b were detected as well as production of IL-4, IL-10, IL-12 and INF-gamma in response to Nlac PorB, consistent with induction of both a Th1-type and a Th2-type immune response.
5528 18209042 IFN-gamma itself induced IL-27p28 expression and survival but did not promote relevant CCR7-driven migration or activated Th-1 cell recruitment capacity in MDDC.
5529 18209042 Administered in association with classical maturation stimuli such as CD40 or TLR-4 stimulation, IFN-gamma up-regulated IL-27 and IL-12 production, CCR7-driven migration, and activated Th-1 cell recruitment, whereas it decreased IL-10 production and STAT3 phosphorylation.
5530 18209042 CD38 signaling, which orchestrates migration, survival, and Th-1 polarizing ability of mature MDDC, was involved in IFN-gamma-mediated effects.
5531 18256207 This work aimed at evaluating the degree of anemia and the plasmatic profile of the cytokines tumor necrosis factor alpha (TNF-alpha), gamma interferon (IFN-gamma), interleukin-12 (IL-12), migration inhibitory factor (MIF), and IL-10 and the monocyte chemotactic protein-1 (MCP-1) chemokine, as well as evaluating the presence of antibodies directed to components of the normal erythrocyte membrane and to cardiolipin in individuals with malaria from the Brazilian Amazon.
5532 18256207 Significant increases in the concentrations of TNF-alpha, IFN-gamma, MIF, and MCP-1 were observed in patients with P. falciparum and P. vivax malaria, whereas the concentrations of IL-10 was increased only in patients with P. vivax infection.
5533 18256207 Higher concentrations of IL-12 and IL-10 were observed in the P. falciparum anemic patients, while for TNF-alpha this profile was observed in the nonanemic ones.
5534 18256207 This work aimed at evaluating the degree of anemia and the plasmatic profile of the cytokines tumor necrosis factor alpha (TNF-alpha), gamma interferon (IFN-gamma), interleukin-12 (IL-12), migration inhibitory factor (MIF), and IL-10 and the monocyte chemotactic protein-1 (MCP-1) chemokine, as well as evaluating the presence of antibodies directed to components of the normal erythrocyte membrane and to cardiolipin in individuals with malaria from the Brazilian Amazon.
5535 18256207 Significant increases in the concentrations of TNF-alpha, IFN-gamma, MIF, and MCP-1 were observed in patients with P. falciparum and P. vivax malaria, whereas the concentrations of IL-10 was increased only in patients with P. vivax infection.
5536 18256207 Higher concentrations of IL-12 and IL-10 were observed in the P. falciparum anemic patients, while for TNF-alpha this profile was observed in the nonanemic ones.
5537 18272768 Notably, PCV2-induced IL-10 led to effective repression of IL-12 in blood peripheral mononuclear cells (PBMCs).
5538 18305406 Upon recognition of the heat-denatured tumor antigens, macrophages and dendritic cells were found to acutely upregulate the expression of co-stimulatory molecules such as B7.2, as well as the secretion of inflammatory cytokines such as IL-12 and TNF-alpha.
5539 18313150 Results from a protein cytokine array showed significant elevations over time in interleukin (IL)-1alpha, IL-1beta, IL-6, IL-12, MCP-1, IFNgamma, TNFalpha, MIP-1alpha, and RANTES in homogenized brain samples of infected mice.
5540 18323802 Vaccination of B-CLL patients with autologous dendritic cells can change the frequency of leukemia antigen-specific CD8+ T cells as well as CD4+CD25+FoxP3+ regulatory T cells toward an antileukemia response.
5541 18323802 We observed a decrease of peripheral blood leukocytes and CD19+/CD5+ leukemic cells in five patients, three patients showed a stable disease and four patients progressed despite DC vaccination.
5542 18323802 A significant increase of specific cytotoxic CD8+ T lymphocytes against the leukemia-associated antigens RHAMM or fibromodulin was detected in four patients after DC vaccination.
5543 18323802 In patients with a clinical response, an increase of interleukin 12 (IL-12) serum levels and a decrease of the frequency of CD4+CD25(+)FOXP3+ T regulatory cells were observed.
5544 18362129 Cytokine secretion from spleen cells of mice vaccinated with the encapsulated vjbR::Tn5 revealed elevated secretion of gamma interferon and interleukin-12, but no interleukin-4, suggesting an induction of a T helper 1 response reflecting the enhanced immunity associated with microencapsulation.
5545 18378164 In mice, the purified ESAT-6-MPT64 fusion protein elicited stronger humoral response, greater splenic lymphocyte stimulated index, and higher levels of IFN-gamma and IL-12 production than that of the single MPT64 inoculation group, and rendered modest protection on the experimental tuberculosis mouse models.
5546 18386791 Combination of Fasl and GM-CSF confers synergistic antitumor immunity in an in vivo model of the murine Lewis lung carcinoma.
5547 18386791 Gene transfer of Fas ligand (FasL) to tumor cells has been demonstrated to inhibit tumor growth in vivo, and neutrophils are primarily responsible for this immunoprotection.
5548 18386791 The granulocyte-macrophage colony stimulating factor (GM-CSF) secreted by tumor vaccine can recruit dendritic cells (DCs) for efficient antigen presentation to T cells that generate the tumor-specific response.
5549 18386791 To investigate whether the combination of FasL and GM-CSF can efficiently suppress tumor growth, we have established Lewis lung carcinoma (LLC-1) cells that are transduced with GM-CSF (LLC/GM-CSF), FasL (LLC/FasL) or both genes (LLC/FasL/GM-CSF) to test their tumorigenic potential in vivo.
5550 18386791 In contrast, none of the mice injected with LLC/FasL or LLC/FasL/GM-CSF develop tumors.
5551 18386791 Specific memory immune response and delayed LLC-1 tumor growth are found in mice immunized with LLC-1/FasL or LLC-1/FasL/GM-CSF.
5552 18386791 Furthermore, therapeutic effects are observed only when LLC-1/FasL/GM-CSF tumor vaccine is employed to retard growth of preexisting LLC-1 tumors.
5553 18386791 Tumor growth is also completely suppressed in mice injected with a mixture of LLC-1 and LLC-1/FasL/GM-CSF.
5554 18386791 In addition, IL-12 production, cytotoxic T-cell activity and IgG against LLC-1 are manifested in mice injected with LLC/FasL/GM-CSF.
5555 18386791 Our data show that FasL-induced pathway triggers expression of proinflammatory cytokines, including IL-1 beta, IL-6, MIP-2 and MCP-1, while GM-CSF-dependent pathway promotes functional maturation and activation of DCs.
5556 18386791 Taken together, the results indicate that dual gene-based delivery with FasL and GM-CSF may serve as a more effective tumor vaccine to suppress lung cancer cell growth in vivo.
5557 18400975 In contrast, their capacity to allostimulate naive CD4(+) T cells resembled that of conventional immature DCs and could be increased by TLR4 stimulation.
5558 18400975 Th1 polarization of CD4(+) T cells and production of interleukin 12p70 (IL-12p70) by ssRNA-DCs were selectively abrogated in response to a late TLR4, but not in response to a CD40, maturation signal.
5559 18400975 Inhibition of p38 mitogen-activated protein kinase partially restored IL-12p70 secretion but did not restore Th1 polarization, whereas addition of exogenous IL-12 led to recovery of Th1 polarization.
5560 18405984 In addition, induction of IFNgamma, IL4, IL10, IL12 secretion in presence of GSPL was investigated in PBMC from normal individuals.
5561 18405984 ROS and RNI in addition to IFNgamma and IL12 were induced by GSPL.
5562 18419254 Effects of interleukin-12 and interleukin-15 on measles-specific T-cell responses in vaccinated infants.
5563 18419254 To define potential mechanisms, we investigated age-related differences in measles-specific T-cell proliferation, CD40-L expression, and IFN-gamma production after measles immunization, and the effects of rhIL-12 and rhIL-15 on these responses.
5564 18419254 CD40-L expression by infant and adult T cells stimulated with measles antigen was comparable, but fewer infant CD40-L(+) T cells expressed IFN-gamma.
5565 18425373 IL-15 exerts its effect on innate and acquired immunity with the most prominent action in NK cells and CD8(+) memory T cells.
5566 18425373 In our experiments, in a model of B78-H1 murine transplantable melanoma, tumor-bearing mice were treated with different cytokine-gene modified tumor cell vaccines (producing TNF-alpha, GM-CSF, IL-12 or IL-6/sIL-6R) followed by a series of IL-15 injections.
5567 18425373 Tumors treated with the combination of B78-H1 melanoma cells secreting IL-12 (B78/IL-12 vaccine) and IL-15 were heavily infiltrated by granulocytes.
5568 18425373 IL-15, either alone or in combination with the B78/IL-12 vaccine, influenced infiltration of tumors with CD3(+) lymphocytes, CD4(+)and CD8(+).
5569 18425373 IL-15 exerts its effect on innate and acquired immunity with the most prominent action in NK cells and CD8(+) memory T cells.

5577 18435687 Although both Th1 (IFN-gamma, TNF-alpha and IL-12) and Th2 (IL-4 and IL-10) cytokines were secreted by the PBMCs of the P. vivax-exposed individuals in response to PvTRAg, the overall response was more inclined towards Th2.
5578 18456294 The clinical signs correlated with the systemic TNF-alpha and IL-12 levels.
5579 18456294 ORF1 vaccination elevated T-helper (Th)1 (IFN-gamma; P<0.001) and Th2 (IL-13; P<0.05) cytokine levels on DPI 35, while ORF2 markedly elevated the expression of the humoral immunity- and Th-2-related cytokine IL-10 (P<0.001) on DPI 35.
5580 18490715 IL-12p40 is a natural antagonist which inhibits IL-12- and IL-23-mediated biological activity by blocking the binding of IL-12/23 to their receptors.
5581 18490715 Moreover, the differential CD8(+) T cell response by IL-12p40 was still observed in IL-12Rbeta2 knockout (IL-12Rbeta2KO), but not in IL-12Rbeta1 knockout (IL-12Rbeta1KO) mice, indicating that IL-12p40 is a cytokine which can modulate Ag-specific T cell responses depending on IL-12Rbeta1.
5582 18490717 We observed that radiosensitive and radioresistant cells played distinct roles in the innate response to flagellin, with the radiosensitive cells producing the majority of the TNF-alpha, IL-12, and IL-6 cytokines and the radioresistant cells most of the KC, IP-10, and MCP-1 cytokines.
5583 18490717 Further studies revealed that hemopoietic and nonhemopoietic expression of the cytokines TNF-alpha and IL-6, but not IL-1, played an important role in promoting flagellin-induced Ab responses.
5584 18502198 In addition, CIM significantly promotes an elevated level of IL-4 and IFN-gamma in antigen-specific CD4(+) T cells and a robust antigen-specific cytotoxic response in the animals immunized with pcD-S2 plus CIM.
5585 18502198 Further, CIM induces pro-inflammatory cytokine expression such as the IL-12 and down-regulates anti-inflammatory cytokine expression such as IL-10 and TGF-beta, which may lead to an impairment of CD4(+)CD25(+) Treg cell-mediated suppression.
5586 18519662 Paired, but not solitary combinations of polyinosine:polycytadilic acid (P[I:C]; TLR3 agonist) and CpG DNA (ODN1826l; TLR9 agonist) stimulated IL-12 secretion from DCs in vitro and synergized with vaccination to achieve potent tumor rejection.

5589 18523260 In this study, we examined the ability of therapeutic vaccination with SIV-DNA+IL-12 or IL-15 as molecular adjuvants to improve DNA vaccine potency and to enhance memory immune responses in SIV-infected macaques.
5590 18523260 Our results demonstrate that incorporating IL-12 into the vaccine induces SIV-specific CD8 effector memory T cell (T(EM)) functional responses and enhances the capacity of IFN-gamma-producing CD8 T(EM) cells to produce TNF.
5591 18523260 Lower levels of PD-1 were expressed on T cells acquiring dual function upon vaccination as compared with mono-functional CD8 T(EM) cells.

5622 18524883 Our data show that the difference between the therapeutic administration of BCG and RUTI resides mainly in the stronger activation of IFN-gamma(+) CD4(+) cells and CD8(+) cells against tuberculin purified protein derivative, ESAT-6, and Ag85B that RUTI generates.
5623 18524883 Both vaccines also triggered a specific immune response against the M. tuberculosis structural antigens Ag16kDa and Ag38kDa and a marked mRNA expression of IFN-gamma, tumor necrosis factor, interleukin-12, inducible nitric oxide synthase, and RANTES in the lung.
5624 18540530 The method of immunization will confer significant properties to the potency of the vaccine and might require augmentation with certain adjuvant agents like interleukin-12 and granulocyte-macrophage colony-stimulating factor.
5625 18550728 C57BL/6 mice vaccinated with T. cruzi G1 (TcG1)-, TcG2-, or TcG4-encoding plasmids and cytokine (interleukin-12 and granulocyte-macrophage colony-stimulating factor) expression plasmids elicited a strong Th1-type antibody response dominated by immunoglobulin G2b (IgG2b)/IgG1 isotypes.
5626 18550728 Subsequently, the serum and cardiac levels of IFN-gamma and tumor necrosis factor alpha and infiltration of inflammatory infiltrate in the heart were decreased in vaccinated mice during the course of infection and chronic disease development.
5627 18562051 Co-injection of pVAX/mIL-18 significantly increased the production of IFN-gamma and IL-12, indicating that IL-18 enhances the Th1-dominant immune response.
5628 18562567 Influenza virus vaccination induces interleukin-12/23 receptor beta 1 (IL-12/23R beta 1)-independent production of gamma interferon (IFN-gamma) and humoral immunity in patients with genetic deficiencies in IL-12/23R beta 1 or IFN-gamma receptor I.
5629 18562567 To investigate whether protective immune responses can be induced in the absence of normal interleukin-12/23/gamma interferon (IL-12/23/IFN-gamma) axis signaling, we vaccinated with the seasonal influenza virus subunit vaccine two patients with complete IL-12/23 receptor beta1 (IL-12/23R beta 1) deficiencies, two patients with partial IFN-gamma receptor I (pIFN-gamma RI) deficiencies, and five healthy controls.
5630 18562567 Interestingly, influenza virus-specific IFN-gamma responses were IL-12/23 independent, in striking contrast to mycobacterium-induced IFN-gamma production.
5631 18562567 In conclusion, influenza virus vaccination induces IL-12/23-independent IFN-gamma production by T cells and can result in sufficient humoral protection in both IL-12/23R beta 1- and pIFN-gamma RI-deficient individuals.

5641 18562567 To investigate whether protective immune responses can be induced in the absence of normal interleukin-12/23/gamma interferon (IL-12/23/IFN-gamma) axis signaling, we vaccinated with the seasonal influenza virus subunit vaccine two patients with complete IL-12/23 receptor beta1 (IL-12/23R beta 1) deficiencies, two patients with partial IFN-gamma receptor I (pIFN-gamma RI) deficiencies, and five healthy controls.
5642 18562567 Interestingly, influenza virus-specific IFN-gamma responses were IL-12/23 independent, in striking contrast to mycobacterium-induced IFN-gamma production.

5644 18566447 However, DC/breast cancer fusions stimulate a mixed T cell response characterized by the expansion of both activated and regulatory T cell populations, the latter of which is characterized by expression of CTLA-4, FOXP3, IL-10, and the suppression of T cell responses.
5645 18566447 Our results demonstrate that IL-12, IL-18, and TLR 9 agonist CpG oligodeoxynucleotides reduce the level of fusion-mediated regulatory T cell expansion.
5646 18579264 The stimulated T cells produced higher amount of IL-4 and IL-10 than IFN-gamma, TNF-alpha, and IL-12 indicating a Th2 type of response bias.
5647 18600182 Unmodified freeze-thaw tumor cell lysates inhibited the toll-like receptor-induced maturation and function of bone marrow-derived DCs, preventing up-regulation of CD40, CD86, and major histocompatibility complex class II, and reducing secretion of inflammatory cytokines [interleukin (IL)-12 p70, tumor necrosis factor-alpha, and IL-6].
5648 18600182 Although IL-10 secretion was increased by lysate-pulsed DCs, this was not responsible for the observed suppression of IL-12.
5649 18600259 A novel cytokine interleukin (IL)-23 bears a structural and functional resemblance to IL-12.
5650 18600259 Interestingly, whereas IL-23 still induced tumor-specific CD8(+) T-cell responses, it could not activate natural killer (NK) cells in vitro and in vivo.
5651 18625731 Splenocytes from immunized mice proliferated in response to antigen and released interleukin-12 and gamma interferon (IFN-gamma).
5652 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.
5653 18656517 Out of seven sub-fractions: F2.1-F2.7, only four F2.4-F2.7 (89.9-97.1 kDa), individually or in pooled sub-fractions (P4-7), stimulated Th1-type remarkable lymphoproliferative, NO, IFN-gamma and IL-12 responses in Leishmania-infected cured/exposed patients and hamsters.
5654 18694298 Detailed analysis of the immune response revealed that the combined DNA vaccine/KLKL(5)KLK mixture stimulated higher IL-12 secretion, resulted in significantly more CD4(+)/CD44(high) and CD8(+)/CD44(high) T-cell production (p < 0.01), elicited 1.5- to 1.8-fold higher interferon-gamma (IFN-gamma) production, and produced stronger antigen-specific cytotoxic T lymphocyte activity than the combined DNA vaccine alone.
5655 18708593 DnaK induced the activation of MAPKs and NF-kappaB in DC and the production of the proinflammatory cytokines IL-6, TNF-alpha, and IL-12 p40, as well as low levels of IL-10.
5656 18708593 DnaK induced phenotypic maturation of DC, as demonstrated by an up-regulation of costimulatory molecules CD40, CD80, and CD86.
5657 18708593 DnaK stimulated DC through TLR4 and the adapters MyD88 and Toll/IL-1R domain-containing adaptor-inducing IFN-beta (TRIF) that mediated differential responses.
5658 18708593 DnaK induced activation of MAPKs and NF-kappaB in a MyD88- or TRIF-dependent manner.
5659 18708593 In contrast, DnaK induced DC maturation in a TRIF-dependent, MyD88-independent manner.
5660 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.
5661 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.
5662 18716452 The levels of TNF-alpha and IFN-gamma induced by LVS were 5 times lower than those induced by the Pohang isolate.
5663 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.
5664 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.

5670 18753198 Seven rhesus macaques per group were primed twice with multigenic SIV plasmid DNA with or without interleukin-12 (IL-12) DNA or IL-15 DNA.
5671 18753198 After a multigenic replicating Ad-SIV immunization, all groups received two booster immunizations with SIV gp140 and SIV Nef protein.
5672 18753198 Macaques that received IL-15-DNA exhibited higher peak anti-Nef titers, a more rapid anti-Nef anamnestic response postchallenge, and expanded CD8(CM) T cells 2 weeks postchallenge compared to the DNA-only group.
5673 18756049 In the atopic asthmatics, BCG significantly increased IL-10 and IL-12 production from DCs.
5674 18756049 In conclusion, administration of BCG together with D. farinae extract effectively decreased IL-5 production from T cells, probably through the action of IL-10 and IL-12 released from DCs in D. farinae-sensitive asthmatics.
5675 18756049 In the atopic asthmatics, BCG significantly increased IL-10 and IL-12 production from DCs.

5677 18789542 CD14+ cells are required for IL-12 response in bovine blood mononuclear cells activated with Toll-like receptor (TLR) 7 and TLR8 ligands.
5678 18789542 Single-stranded viral RNA (ssRNA) was recently identified as the natural ligand for TLR7 and TLR8. ssRNA sequences from viruses, as well as their synthetic analogues stimulate innate immune responses in immune cells from humans and mice, but their immunostimulatory activity has not been investigated in ruminants.
5679 18789542 In vitro incubation of bovine peripheral blood mononuclear cells (PBMCs) with ORN-induced production of IL-12, IFN-gamma and TNF-alpha.
5680 18789542 Depletion of CD14+ cells from PBMC abrogated the IL-12 response and consequently the IFN-gamma response, suggesting that CD14+ cells are required for PBMC immune activation with ORN.
5681 18789542 Consistent with these findings, the putative receptors for ORN (TLR7 and TLR8) were expressed at higher levels in the CD14+ fraction than the CD14- PBMC fraction.

5686 18789542 Consistent with these findings, the putative receptors for ORN (TLR7 and TLR8) were expressed at higher levels in the CD14+ fraction than the CD14- PBMC fraction.
5687 18789542 CD14+ cells are required for IL-12 response in bovine blood mononuclear cells activated with Toll-like receptor (TLR) 7 and TLR8 ligands.
5688 18789542 Single-stranded viral RNA (ssRNA) was recently identified as the natural ligand for TLR7 and TLR8. ssRNA sequences from viruses, as well as their synthetic analogues stimulate innate immune responses in immune cells from humans and mice, but their immunostimulatory activity has not been investigated in ruminants.

5692 18795121 Interleukin 12 (IL-12) can activate type I NKT cells to produce interferon-gamma (IFN-gamma), whereas type II NKT cells may produce IL-13.
5693 18795121 The high-affinity chain of IL-13Ralpha2 may act as negative inhibitor, suppressing the action of IL-13 and helping to maintain tumor immunosurveillance.
5694 18795121 We conclude that IL-12 gene therapy, followed by continuous administration of IL-13Ralpha2-Fc gene along with 7A-drug has antitumor activity involving the high production of proinflammatory cytokines and low immune suppression, specifically by NK1.1(+)T cells producing IL-13 and IL-10.

5698 18809450 Immunisation of mice with spores that co-expressed LLO with Protective Antigen (PA) of Bacillus anthracis generated an increase in IgG2a against PA, toxin-neutralising activity coupled with specific IFN-gamma and IL-12 (and reduced IL-4) responses of splenocytes, both indicative of an enhanced Th1 response.
5699 18815231 Gamma interferon (IFN-gamma), interleukin 10 (IL-10), IL-12, and low levels of IL-13 and IL-5 but no IL-4 were secreted into the culture supernatant of cord blood mononuclear cells.
5700 18815231 Intracellular staining showed that IL-10 and IL-12 were produced by monocytes and that IFN-gamma was produced by natural killer (NK) cells but not by CD4(+) or CD8(+) T cells.
5701 18815231 In contrast, in the peripheral blood samples collected from babies 13 weeks post-BCG vaccination, IFN-gamma was detected within CD4(+) and CD8(+) cells.
5702 18815231 Gamma interferon (IFN-gamma), interleukin 10 (IL-10), IL-12, and low levels of IL-13 and IL-5 but no IL-4 were secreted into the culture supernatant of cord blood mononuclear cells.

5705 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.
5706 18819411 Synthesis of several serum interleukins (IL-2, IL-10) did not changed 4 and 24 hours after inoculation irrespective from dose of PST.
5707 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).
5708 18940198 While it is well established that CD4(+) T lymphocytes play a crucial role in the initiation, progression and persistence of asthma, the role of CD8(+) T cells is less understood.
5709 18940198 CD8(+) T cells form functionally similar subsets which exhibit similar cytokine profiles as Th1 and Th2 cells, known as Tc1 and Tc2.
5710 18940198 Evidence from animal studies suggest that CD8(+) T cells are capable of regulating IgE production through the induction of IL-12 and IL-18 production in dendritic cells, and that CD8(+) T cells may act to moderate Th2 polarisation within the localised lymph nodes during allergic sensitisation.
5711 18945879 Downregulation of CD40 ligand response in monocytes from sepsis patients.
5712 18945879 Here, the response of monocytes to CD40 ligand (CD40L) for patients with sepsis due to infection with gram-negative organisms has been analyzed.
5713 18945879 Compared to cells from controls, monocytes from septic patients showed significantly reduced production of tumor necrosis factor alpha, interleukin-1beta (IL-1beta), and IL-12 and were unable to acquire high levels of CD80 and CD86 molecules.
5714 18945879 In addition, costimulation of autologous CD4+ T lymphocytes by CD40L-activated monocytes from septic patients failed to induce cell proliferation and gamma interferon production.

5730 19022317 Our results indicate that both liposomes and microspheres prove to be better adjuvants compared to conventional alum as revealed by enhanced antibody titers, lymphocyte proliferation and significant enhancement in both Th1(IL-12, IFN-gamma) and Th2 (IL-4, IL-10) cytokines.
5731 19036811 We therefore expressed a viral protein that constitutively activates NF-kappaB, vFLIP from Kaposi's sarcoma-associated herpesvirus (KSHV), in a lentivector to mature DCs. vFLIP activated NF-kappaB in mouse bone marrow-derived DCs in vitro and matured these DCs to a similar extent as lipopolysaccharide; costimulatory markers CD80, CD86, CD40, and ICAM-1 were upregulated and tumor necrosis factor alpha and interleukin-12 secreted.

5743 19056444 Results showed that although the basal production of IFN-gamma and IL-6 was impaired (P<0.05) in PBMCs of neonatal foals at birth, the basal production of IL-8, IL-12(p35/p40) and IL-23(p19/p40) were either in excess of or comparable to that of older foals.
5744 19056444 In response to Rhodococcus equi and CpG-ODN stimulation in vitro, PBMCs of neonatal foals showed increased (P<0.05) expression of IFN-gamma and IL-6, and preferentially increased expression of either IL-23(p19/p40) with R. equi stimulation or IL-12(p35/p40) with CpG-ODN stimulation.

5747 19099654 [Immunoregulation effects in vitro of the xenoprotein in combination with recombinant human granulocyte-macrophage colony stimulating factor and bacillus Calmette-Guerin].
5748 19099654 This study was aimed to investigate the effects of xenogeneic antigen neu-Fc in combination with the recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF) and Bacillus Calmette-Guerin (BCG) on the regulation of Th1 and Th2 immune response in vitro.
5749 19099654 The production of IL-12 and IL-10 was measured by ELISA.
5750 19099654 Compared with neu-Fc or GM-CSF or BCG treatment alone, neu-Fc in combination with GM-CSF and BCG significantly stimulated IL-12 production and inhibited IL-10 production (p < 0.01).
5751 19107404 This study aims at investigating the efficacy of a novel vaccine consisting of modified HPV 16E7 fused with human cytotoxic T-lymphocyte antigen 4 (CTLA4).
5752 19107404 C57BL/6 (H-2b) mice immunized with low dose of the fusion protein (10 microg) produced higher titer antibody and stronger specific CTL response, and expressed higher levels of IFN-gamma and IL-12, compared with those immunized with HPVml6E7 only or admixture of HPVml6E7 and CTLA4, or PBS; and were protected from lethal dose tumor challenge.
5753 19109450 We measured the activation of the antigen-presenting major histocompatibility complex (MHC) class II molecule, costimulatory molecules CD40 and CD86, the cytokine interleukin-12 (IL-12), and the transcriptional factor interferon regulatory factor 1 (IRF-1) in monocyte-derived macrophages (mMOs) and dendritic cells (mDCs) of adult horses and foals of different ages (from birth to 3 months of age) infected with virulent R. equi or its avirulent, plasmid-cured derivative.
5754 19109450 R. equi infection promoted comparable expression of costimulatory molecules CD86 and CD40 in foal and adult horse cells.
5755 19124765 Typhi(F1) enhanced the activation and maturation of neonatal CD11c+ dendritic cells, shown by increased expression of CD80, CD86, CD40, and MHC-II cell surface markers and production of proinflammatory cytokines IL-12, TNF-alpha, IL-6, and MCP-1.
5756 19124765 Typhi(F1)-stimulated neonatal DC had improved capacity for Ag presentation and T cell stimulation in vitro and induced F1-specific CD4+ and CD8+ T cell responses when adoptively transferred to newborn mice.
5757 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.
5758 19168736 Again, mice vaccinated through the i.p. and i.v. routes showed high levels of NO production after challenge infection. s.c. vaccination resulted in an increased capacity of the spleen cells to produce prechallenge transforming growth factor beta (TGF-beta) levels during the in vitro antigen recall response, whereas i.p. immunization induced production of prechallenge gamma interferon, interleukin-12 (IL-12), and IL-4 levels, with a Th1 bias.
5759 19188665 Experimental tumor vaccination and adoptive T-cell therapies show that interferon-gamma (IFN-gamma)-producing CD4(+) T helper cells (Th1) can be highly effective in tumor prevention and therapy.
5760 19188665 Th-cell priming against EpCAM inevitably resulted in interleukin-4 (IL-4)-dominated Th2 responses, even under most stringent Th1-inducing conditions.
5761 19188665 To analyze the role of IL-4 in tumor immune evasion, we generated EpCAM-reactive Th1 cells from IL-4.ko mice.
5762 19188665 Inhibition of tumor growth by Th1 cells resulted in intra-tumoral expression of cytokines of the IL-12 family and of IFN-gamma.
5763 19190335 C57BL/6 mouse-derived bone marrow cells were cultured with mouse granulocyte/macrophage colony-stimulating factor (GM-CSF) for 6 days, and CD11c(+) cells were subsequently cultured with GM-CSF, rmIFN-gamma, rmIFN-alpha, rmIL-4, and polyinosinic-polycytidylic acid stabilized by lysine and carboxymethylcellulose for 24 hours to generate DC1s.
5764 19190335 In analogy to their human counterparts, mouse DC1s exhibited surface marker profiles of mature DCs and produced high levels of IL-12 and CXCL10.
5765 19201385 Here, we used a peptide-pulsed dendritic cell (DC) vaccination model to examine the role of primary cytokines, IL-12 and IFNgamma, elicited by CpG-B adjuvant on CD8 T cell priming and memory CD8 T cell development.
5766 19201385 Furthermore, IFNgamma induced by CpG was required in vivo for optimal production of IL-12, which in turn, influenced effector CD8 T cell longevity.

5769 19215191 Here we tested a second-generation Triplex DNA-based vaccine (Tri-DNA), consisting of the combination of three gene components (a transmembrane-extracellular domain fragment of the Neu gene, IL-12 genes, and the H-2D(q) allogeneic MHC gene), carried by separate plasmids.
5770 19224636 TB cases had significantly higher levels of IFN-gamma(+)TNF-alpha(+)IL-2(+)CD4(+)T cells compared with contacts.
5771 19224636 TB cases also had a significantly higher proportion of cells single-positive for TNF-alpha, but lower proportion of cells producing IL-2 alone and these differences were seen for both CD4(+)and CD8(+) T cells.
5772 19224636 Cytokine profiles from culture supernatants were significantly biased toward a Th1 phenotype (IFN-gamma and IL-12(p40)) together with a complete abrogation of IL-17 secretion in TB cases.
5773 19238013 DCs purified from the Ad-RANTES-E1A-treated E.G-7 tumors secreted significantly higher levels of interferon-gamma and interleukin-12, as compared with control groups and more efficiently enhanced CD8+ T-cell response.

5816 19309560 F1, V, and F1-V proteins engaged TLR2 signalling and activated IL-6 and CXCL-8 production by monocytes, without affecting the expression of TNF-alpha, IL-12, IL-10, IL-1beta, and CXCL10.
5817 19424635 BM-DCs were loaded with MC38 colon carcinoma cell lysate (TAg) alone, to become partially differentiated, or were additionally stimulated with inflammatory cytokines such as TNF-alpha, IFN-gamma, or IL-12 to reach complete maturity.
5818 19424635 BM-DCs simultaneously stimulated with TAg and cytokines (especially IL-12 or IFN-gamma+IL-12) were in vitro more effective immune response activators than BM-DC/TAg cells.
5819 19424635 BM-DCs were loaded with MC38 colon carcinoma cell lysate (TAg) alone, to become partially differentiated, or were additionally stimulated with inflammatory cytokines such as TNF-alpha, IFN-gamma, or IL-12 to reach complete maturity.
5820 19424635 BM-DCs simultaneously stimulated with TAg and cytokines (especially IL-12 or IFN-gamma+IL-12) were in vitro more effective immune response activators than BM-DC/TAg cells.
5821 19461875 Upon challenge with uninfected or infected flies, immunized dogs developed a cellular response at the bite site characterized by lymphocytic infiltration and IFN-gamma and IL-12 expression.
5822 19494083 Adherent peritoneal cells from rats treated with HKC-CFA showed upregulated ED2, CD80, and CD86 expression; an increase in the level of production of anticryptococcal metabolites; and the enhanced production of interleukin-12 (IL-12) in comparison with the findings for cells from rats treated with CFA-phosphate-buffered saline (PBS).
5823 19494083 Adherent peritoneal cells from rats treated with PSC-CFA, however, also presented upregulated ED2, CD80, and CD86 expression compared to the level of expression for peritoneal cells from controls, but these cells showed an increase in arginase activity and decreased levels of production of IL-12 and tumor necrosis factor (TNF) compared with the activity and levels of production by peritoneal cells from CFA-PBS-treated rats.
5824 19494083 Adherent peritoneal cells from rats treated with HKC-CFA showed upregulated ED2, CD80, and CD86 expression; an increase in the level of production of anticryptococcal metabolites; and the enhanced production of interleukin-12 (IL-12) in comparison with the findings for cells from rats treated with CFA-phosphate-buffered saline (PBS).
5825 19494083 Adherent peritoneal cells from rats treated with PSC-CFA, however, also presented upregulated ED2, CD80, and CD86 expression compared to the level of expression for peritoneal cells from controls, but these cells showed an increase in arginase activity and decreased levels of production of IL-12 and tumor necrosis factor (TNF) compared with the activity and levels of production by peritoneal cells from CFA-PBS-treated rats.
5826 19494321 Bone marrow-derived mesenchymal stromal cells (MSC) possess an immune plasticity manifested by either an immunosuppressive or, when activated with IFN-gamma, an APC phenotype.
5827 19494321 We observed that human MSC and macrophages expressed TLR3 and TLR4 at comparable levels and TLR-mediated activation of MSC resulted in the production of inflammatory mediators such as IL-1beta, IL-6, IL-8/CXCL8, and CCL5.
5828 19494321 IFN-alpha or IFN-gamma priming up-regulated production of these inflammatory mediators and expression of IFNB, inducible NO synthase (iNOS), and TRAIL upon TLR activation in MSC and macrophages, but failed to induce IL-12 and TNF-alpha production in MSC.
5829 19494321 In addition, IFN priming combined with TLR activation may increase immune responses induced by Ag-presenting MSC through presentation of Ag in an inflammatory context, a mechanism that could be applied in a cell-based vaccine.
5830 19503834 Analysis of the cytokine responses in immunized mice revealed that all the vaccinated groups produced prechallenge interferon-gamma, interleukin-12 and interleukin-4.
5831 19519403 In this view, new therapeutic approaches may be planned including: i) pre-screening of melanoma patients for IL-12Rbeta2 expression to identify potential responders, ii) administration of small and less frequent doses of IL-12 to avoid toxicity and iii) targeting of IL-12 to IL-12R(+) tumor cells, such as local administration in patients with skin tumors or injection of IL-12 fused to an antibody specific to tumor cells.
5832 19542458 The efficacy was supported by a surge in inducible NO synthase, IFN-gamma, TNF-alpha, and IL-12 mRNA levels along with extreme down-regulation of TGF-beta, IL-4, and IL-10.
5833 19564349 Dendritic cells require a systemic type I interferon response to mature and induce CD4+ Th1 immunity with poly IC as adjuvant.
5834 19564349 Relative to several other toll-like receptor (TLR) agonists, we found polyinosinic:polycytidylic acid (poly IC) to be the most effective adjuvant for Th1 CD4(+) T cell responses to a dendritic cell (DC)-targeted HIV gag protein vaccine in mice.
5835 19564349 To identify mechanisms for adjuvant action in the intact animal and the polyclonal T cell repertoire, we found poly IC to be the most effective inducer of type I interferon (IFN), which was produced by DEC-205(+) DCs, monocytes, and stromal cells.
5836 19564349 Antibody blocking or deletion of type I IFN receptor showed that IFN was essential for DC maturation and development of CD4(+) immunity.
5837 19564349 STAT 1 was also essential, in keeping with the type I IFN requirement, but not type II IFN or IL-12 p40.
5838 19564349 Induction of type I IFN was mda5 dependent, but DCs additionally used TLR3.
5839 19564349 In bone marrow chimeras, radioresistant and, likely, nonhematopoietic cells were the main source of IFN, but mda5 was required in both marrow-derived and radioresistant host cells for adaptive responses.
5840 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.
5841 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.
5842 19578737 To induce DC1, bone marrow cells (BMCs) from BALB/c mice were cultured with GM-CSF, IL-12 and IFN-gamma.
5843 19596413 Since HER2 (also known as ErbB-2, neu, and HER2/neu) is frequently overexpressed on cancer cells, HER2-targeted delivery of IL-12 to tumors may be a promising strategy for enhancing antitumor immunity.
5844 19596413 Elevated IL-12 and interferon-gamma (IFN-gamma) levels, increased infiltration of CD4(+) and CD8(+) T cells, and reduced vascular endothelial growth factor (VEGF) expression in the tumors, as well as enhanced cytolytic activity of splenocytes were noted in the treated mice.
5845 19596413 Since HER2 (also known as ErbB-2, neu, and HER2/neu) is frequently overexpressed on cancer cells, HER2-targeted delivery of IL-12 to tumors may be a promising strategy for enhancing antitumor immunity.
5846 19596413 Elevated IL-12 and interferon-gamma (IFN-gamma) levels, increased infiltration of CD4(+) and CD8(+) T cells, and reduced vascular endothelial growth factor (VEGF) expression in the tumors, as well as enhanced cytolytic activity of splenocytes were noted in the treated mice.
5847 19609245 Generation of human dendritic cells that simultaneously secrete IL-12 and have migratory capacity by adenoviral gene transfer of hCD40L in combination with IFN-gamma.
5848 19609245 In this study, we exploit an adenoviral vector encoding human CD40 ligand (CD40L), Ad5hCD40L, to establish DCs that feature both migration potential and prolonged secretion of the key T-helper 1 cytokine interleukin-12p70 (IL-12p70).
5849 19609245 Finally, DCs transduced with both Ad5hCD40L and an adenoviral vector encoding the melanoma antigen MelanA/MART-1 and treated with MC and IFN-gamma efficiently primed naive autologous CD8+ T cells into antigen-specific cytotoxic T lymphocyte.
5850 19609245 This strategy to generate DCs that exert both migration capacity and prolonged IL-12p70 secretion after intracellular CD40L expression and IFN-gamma treatment has the potential to further improve current DC vaccination protocols.
5851 19615961 Compared to plasmid encoding HSP65, pECANS DNA immunization elicited remarkably higher levels of IFN-gamma production by both CD4(+) and CD8(+) T cells, which were coupled with higher frequencies of antigen-specific T cells and higher CTL activity.
5852 19615961 Significantly enhanced levels of Th1 cytokines (IFN-gamma and IL-12) and increased serum IgG2a/IgG1 ratio were also noted, indicating a predominant Th1 immune response achieved by pECANS DNA immunization.
5853 19652662 WAg 206, unlike WAg 207, did not elicit inflammatory cytokine production (TNFalpha, IL-1beta, IL-12) or costimulatory molecule expression (HLA-DR, CD83, CD80, CD86) by human MDDCs in vitro.
5854 19654068 However, a mixed Th1/Th2 cell response was evidenced in BLG-reactivated splenocytes from mice intranasally pretreated, with enhanced secretions of Th1 cytokines (IFN-gamma and IL-12) and Th2 cytokines (IL-4 and IL-5) whereas only production of Th1 cytokines, but not Th2 cytokines, was enhanced in BLG-reactivated splenocytes from mice orally pretreated.
5855 19667099 Type I interferon (IFN alpha) acts directly on human memory CD4+ T cells altering their response to antigen.
5856 19667099 The aim of this study was to examine the impact of IFNalpha on the function of human memory CD4(+) T cells using the recall Ags purified protein derivative, tetanus toxoid, and hemagglutinin.
5857 19667099 Purifying the memory CD4(+)CD45RO(+) T cells confirmed IFNalpha acted directly on these cells and not via an intermediate.
5858 19667099 The T cells could be divided into two broad categories depending on how IFNalpha effected their responses to cognate Ag: 1) enhanced proliferation and a striking increase in IFNgamma-production compared with smaller increases in IL-10 (increased ratio of IFNgamma:IL-10), and 2) neutral or diminished proliferation coupled with a smaller increase in IFNgamma relative to the increase in IL-10 (reduced IFNgamma:IL-10 ratio).
5859 19671753 For this purpose, we generated three DNA vaccines based on pCMV-F3Ub and pBUD-CE4.1 plasmids encoding for human (h)THcDNA (A), hTH minigene (B), and hTHcDNA in combination with the proinflammatory cytokine interleukin 12 (C), and tested prophylactic and therapeutic efficacy to suppress primary tumor growth and spontaneous metastasis.
5860 19671753 The depletion of CD8(+)T cells completely abrogated the hTH vaccine-mediated anti-NB immune response.
5861 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.
5862 19717136 Adoptive transfer of protective immunity from Cryptosporidium parvum-infected interferon-gamma and interleukin-12-deficient mice to naive recipients.
5863 19717136 We investigated the possibility of transfer immunity from Cryptosporidium parvum-infected interferon-gamma (GKO) and interleukin-12p40 (IL-12KO) deficient C57BL/6 mice to naive mice by transfer of intraepithelial lymphocytes (IELs) and CD4(+) T cells from spleen and mesenteric lymph nodes (MLNs).
5864 19717136 In IL-12KO mice, IELs and also CD4(+) T cells isolated from the spleen and MLNs of donor mice at the peak of infection (day 5) and after resolution (day 15) significantly reduced the parasite excretion, emphasizing the role of interferon-gamma in the host-parasite interaction.
5865 19727134 Dendritic cells (DC) engineered in vitro by DNA encoding OVAhsp70 and IL-15 up-regulated their expressions of CD80, CD86, CCR7 and IL-15Ralpha and promoted their productions of IL-6, IL-12 and TNF-alpha.
5866 19789342 We further find that the capacity of hDCs to prime CTLs is likely controlled by SOCS1-restricted production and signaling of proinflammatory cytokines, such as interleukin-12.
5867 19824039 We also found that a ligand for CD1d-reactive natural killer T (NKT) cells, alpha-glucuronosylceramide (GSL1), enhanced MvP728-induced interleukin-12 production in human dendritic cells and that in vivo coadministration of a NKT ligand with MvP728-Llo or MvP728-survivin enhanced effector-memory cytotoxic T lymphocyte (CTL) responses.
5868 19853910 The effect of R1, R2 and R3 on the expression of the pro- and anti-inflammatory cytokines (TNF-alpha, IL-6, and IL-12) and the co-stimulatory molecules (CD40, CD80, CD86, and MHC class II) in MDDCs was examined.
5869 19853910 The exposure of R1 caused a dose-dependent increase in the expression of TNF-alpha, IL-12, CD86 and CD40, while R2 and R3 did not up-regulate these cytokines and co-stimulatory molecules.
5870 19853910 Furthermore, we found that R1 significantly increased the NF-kappaB expression in the nucleus (in a dose-dependent manner) and promoted the degradation of total IkappaBalpha levels, indicating that the NF-kappaB signaling pathway might involve in an R1-induced DC activation.
5871 19853910 The effect of R1, R2 and R3 on the expression of the pro- and anti-inflammatory cytokines (TNF-alpha, IL-6, and IL-12) and the co-stimulatory molecules (CD40, CD80, CD86, and MHC class II) in MDDCs was examined.
5872 19853910 The exposure of R1 caused a dose-dependent increase in the expression of TNF-alpha, IL-12, CD86 and CD40, while R2 and R3 did not up-regulate these cytokines and co-stimulatory molecules.
5873 19853910 Furthermore, we found that R1 significantly increased the NF-kappaB expression in the nucleus (in a dose-dependent manner) and promoted the degradation of total IkappaBalpha levels, indicating that the NF-kappaB signaling pathway might involve in an R1-induced DC activation.
5874 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.
5875 19863224 CEA and TIMP-1 were analysed on ELISA platforms.
5876 19863224 Patients achieving stable disease showed increasing levels of plasma GM-CSF, TNF-alpha, IFN-gamma, IL-2, and IL-5.
5877 19863224 Patients with progressive disease showed significant increase in CEA and TIMP-1 levels, while patients with stable disease showed relatively unaltered levels.
5878 19906894 The patient exhibited a decreased level of expression of Fc-gammaR in monocytes (CD16, CD32, and CD64), along with increased levels of NK T cells (an increased CD3(+) CD16(+/-) CD56(+/-)/CD3(+) ratio), activated T cells (CD4(+) and CD8(+) cells), and B lymphocytes.
5879 19906894 Enhanced levels of plasmatic cytokines (interleukin-6 [IL-6], IL-17, IL-4, IL-5, and IL-10) as well as an exacerbated ex vivo intracytoplasmic cytokine pattern, mainly observed within NK cells (gamma interferon positive [IFN-gamma(+)], tumor necrosis factor alpha positive [TNF-alpha(+)], and IL-4 positive [IL-4(+)]), CD8(+) T cells (IL-4(+) and IL-5(+)), and B lymphocytes (TNF-alpha(+), IL-4(+), and IL-10(+)).
5880 19906894 The analysis of CD4(+) T cells revealed a complex profile that consisted of an increased frequency of IL-12(+) and IFN-gamma(+) cells and a decreased percentage of TNF-alpha(+), IL-4(+), and IL-5(+) cells.
5881 19915058 Surprisingly, DC.Tbets were impaired in their production of IL-12 family member cytokines (IL-12p70, IL-23, and IL-27) when compared with control DC, and the capacity of DC.Tbet to preferentially prime type 1 T cell responses was only minimally inhibited by cytokine (IL-12p70, IL-23, IFN-gamma) neutralization or receptor (IL-12Rbeta2, IL-27R) blockade during T cell priming.
5882 19933862 Analysis of the cellular immune responses of ubiquitin-conjugated ORFF (UBQ-ORFF) DNA-immunized, uninfected BALB/c mice demonstrated that the vaccine induced enhanced IFN-gamma-producing CD4(+) and CD8(+) T cells compared with nonubiquitinated ORFF DNA vaccine.
5883 19933862 Higher levels of IL-12 and IFN-gamma and the low levels of IL-4 and IL-10 further indicated that the immune responses with UBQ-ORFF were mediated toward the Th1 rather than Th2 type.
5884 19933862 UBQ-ORFF DNA-immunized and -infected mice showed a significant increase in IL-12 and IFN-gamma and significant down-regulation of IL-10.
5885 19933862 Analysis of the cellular immune responses of ubiquitin-conjugated ORFF (UBQ-ORFF) DNA-immunized, uninfected BALB/c mice demonstrated that the vaccine induced enhanced IFN-gamma-producing CD4(+) and CD8(+) T cells compared with nonubiquitinated ORFF DNA vaccine.
5886 19933862 Higher levels of IL-12 and IFN-gamma and the low levels of IL-4 and IL-10 further indicated that the immune responses with UBQ-ORFF were mediated toward the Th1 rather than Th2 type.
5887 19933862 UBQ-ORFF DNA-immunized and -infected mice showed a significant increase in IL-12 and IFN-gamma and significant down-regulation of IL-10.
5888 19952957 In vitro examination of IL-12 DC/PB gammadelta T-cell interactions revealed a potential of PB gammadelta T-cells to negatively regulate the proliferative capacity of CD4 and CD8 T-cells.
5889 19956842 A mammalian co-expression plasmid of glycolipid-anchored-IL-12 (GPI-IL-12) was constructed by subcloning IL-12A chain gene (P35 subunit) and a fusion gene containing GPI-anchor signal sequence of human placental alkaline phosphatase-1 (hPLAP-1) and IL-12B chain gene (P40 subunit) in pBudCE4.1.
5890 19956842 The incorporation of GPI-IL-12 onto exosomes (exosomes-GPI-IL-12, EXO/IL-12) significantly promotes proliferation of T cells, and subsequently increased the release of IFN-gamma.
5891 19956842 A mammalian co-expression plasmid of glycolipid-anchored-IL-12 (GPI-IL-12) was constructed by subcloning IL-12A chain gene (P35 subunit) and a fusion gene containing GPI-anchor signal sequence of human placental alkaline phosphatase-1 (hPLAP-1) and IL-12B chain gene (P40 subunit) in pBudCE4.1.
5892 19956842 The incorporation of GPI-IL-12 onto exosomes (exosomes-GPI-IL-12, EXO/IL-12) significantly promotes proliferation of T cells, and subsequently increased the release of IFN-gamma.
5893 20007364 Association of reduced tumor necrosis factor alpha, gamma interferon, and interleukin-1beta (IL-1beta) but increased IL-10 expression with improved chest radiography in patients with pulmonary tuberculosis.
5894 20007364 The objective of the present study was to correlate the modulation of cytokine expression (interleukin-1 [IL-1], IL-6, IL-8, IL-10, IL-12, gamma interferon [IFN-gamma], interferon-inducible protein [IP-10], and monocyte chemotactic protein 1 [MCP-1]) with the clinical response to 2 months of intensive therapy.
5895 20007364 The levels of expression of TNF-alpha, MCP-1, IFN-gamma, and IL-1beta were decreased; and the level of IL-10 increased in early responders.
5896 20007364 After adjustment for age, gender, and the result of sputum culture for M. tuberculosis, significant differences in the levels of MCP-1 and IP-10 expression were observed between the early and the late responders after 2 months of intensive anti-M. tuberculosis therapy.
5897 20038202 To ensure the stoichiometric expression and assembly of p35 and p40, we expressed a single-chain version of chicken IL-12 (ChIL-12).
5898 20039802 Healthy donor plasma had high immunoglobulin G titers (median, 1:51,200) and lower immunoglobulin A (median, 1:3,200) and immunoglobulin E (median, 1:128) titers to rAls3p-N by enzyme-linked immunosorbent assay. rAls3p-N stimulated interferon gamma (IFN-gamma) and interleukin (IL)-17, but not IL-4, from donor lymphocytes by enzyme-linked immunosorbent spot assay and IL-12 p70, IFN-gamma, IL-17, and IL-10 by cytometric bead array.
5899 20072623 After in vitro stimulation, spleen cells of immunized mice produce high levels of Th1 cytokines and show a prominent mRNA expression of the Th1 transcription factor T-bet, in detriment of the Th2 transcription factor GATA-3.
5900 20072623 Following R. equi challenge, a high H2O2, NO, IL-12, and IFN-gamma content is detected in the organs of immunized mice.
5901 20072623 On the other hand, TNF-alpha and IL-4 levels are markedly lower in the organs of vaccinated mice, compared with the non-vaccinated ones.
5902 20072623 A greater incidence of CD4+ and CD8+ T cells and B lymphocytes is verified in vaccinated mice.
5903 20072623 However, there is no difference between vaccinated and non-vaccinated mice in terms of the frequency of CD4+CD25+Foxp3+ T cells.
5904 20097110 Interferon (IFN)-α, interleukin (IL)-6, IL-1 and tumour necrosis factor (TNF)-α peaked in BALF 24-30h PI, when virus titres and the severity of clinical signs were maximal.
5905 20097110 Whereas IFN-γ and IL-12, but not IL-18, increased in tandem in BALF, serum cytokine concentrations were either undetectable or were up to 100-fold lower.
5906 20097110 The APP C-reactive protein (CRP) and haptoglobin peaked 24h later than the cytokines and reached higher levels in serum than in BALF.
5907 20097110 Lung virus titres tightly correlated with BALF IFN-α, IL-6, IL-1, TNF-α, IFN-γ and IL-12, as well as with serum IL-6, IFN-α and IFN-γ.

5913 20097110 Signs of disease correlated with the same cytokines in BALF and serum, as well as with BALF LBP and serum CRP.
5914 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.
5915 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.
5916 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.
5917 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.
5918 20107534 Increase of Plasma IL-12/p40 Ratio Induced by the Combined Therapy of DNA Vaccine and Lamivudine Correlates with Sustained Viremia Control in CHB Carriers.
5919 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.
5920 20117268 Both naïve and immunized sheep also showed increased CD4 T cell, IL-12 and IFN-alpha responses.
5921 20124603 These DNA were evaluated for their ability to stimulate IL-12, TNF-alpha, IL-10, IFN-gamma and ROS production from spleenocytes as well as NO production from peritoneal macrophages.
5922 20124603 It was observed that TNF-alpha was induced in days 1,3,5 by all Brucella strains DNAs and E. coli DNA, IL-10 only was induced in day 1, IFN- gamma was induced only in day 5 and IL-12 not induced.
5923 20130107 Interferon-gamma secretion is induced in IL-12 stimulated human NK cells by recognition of Helicobacter pylori or TLR2 ligands.
5924 20130107 We found that inhibition of MyD88 homodimerization resulted in decreased production of IFN-γ and that inhibition of the p38 MAPK decreased the production as well as the secretion of IFN-γ.
5925 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.
5926 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.
5927 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.
5928 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.
5929 20156531 Among the combinations of several immune-modulating factors with known effects on DC maturation, we found that stepwise DC maturation with cytokine cocktail (TNF-alpha+IL-6+IL-1 beta+PGE(2)) followed by poly(I:C) stimulation enhanced the production of IL-12 with strong allostimulatory capacity.
5930 20156531 While there were no significant differences between DC matured by simultaneous or sequential activation by cytokine cocktail and poly(I:C) in expression of markers and costimulatory molecules of mature DCs, the delivery of inflammatory signal prior to poly(I:C) results in sustained interleukin-12 expression with reduced IL-10 than DC matured by simultaneous stimulation.

5932 20156531 Furthermore, these DCs retained their responsiveness to CD40L stimulation in secondary IL-12 production and efficiently generated autologous antigen-specific effector T cells as evidenced by ELISPOT assay.
5933 20156531 Among the combinations of several immune-modulating factors with known effects on DC maturation, we found that stepwise DC maturation with cytokine cocktail (TNF-alpha+IL-6+IL-1 beta+PGE(2)) followed by poly(I:C) stimulation enhanced the production of IL-12 with strong allostimulatory capacity.

6016 20390417 Evidence for this came from the marked increase in the IFN-gamma mRNA expression in CD4+ T cells in the draining inguinal lymph nodes, an increase in the number of functional HER-2/neu-specific CTLs, and the increased tumor infiltration of both CD4+ and CD8+ T cells, depletion of which abolishes the antitumor effect of the HER-2/neu DNA vaccine-AC therapy.

6018 20410285 In analyzing the role of type I IFNs in immunity to FPV, we show that they are critical to the secretion of a number of innate and proinflammatory cytokines, including type I IFNs themselves as well as interleukin-12 (IL-12), tumor necrosis factor-alpha (TNF-alpha), IL-6, and IL-1beta, and that deficiency leads to enhanced virus-mediated antigen expression.

6042 20447476 The prime-boost regimen induced not only HBHA-specific IFN-gamma, but also other cytokines, such as IL-12 and TGF-beta, which may be associated with the generation of lung Th1 effector-memory lymphocytes, responsible for the enhanced protection against M. tuberculosis challenge.
6043 20454646 A pivotal role for interleukin-27 in CD8+ T cell functions and generation of cytotoxic T lymphocytes.
6044 20454646 Interleukin (IL)-27, a member of the IL-6/IL-12 heterodimeric cytokine family, acts on naive CD4+ T cells and plays pivotal roles as a proinflammatory cytokine to promote the early initiation of type-1 helper differentiation and also as an antiinflammatory cytokine to limit the T cell hyperactivity and production of pro-inflammatory cytokines.
6045 20454646 Recent studies revealed that IL-27 plays an important role in CD8+ T cells as well.
6046 20454646 Therefore, this article reviews current understanding of the role of IL-27 in CD8+ T cell functions and generation of CTLs.
6047 20488263 This FMIA simultaneously detects innate (IL-1 beta, IL-8, IFN-alpha, TNF-alpha, IL-12), regulatory (IL-10), Th1 (IFN-gamma) and Th2 (IL-4) cytokines.
6048 20490763 F.t. infection up-regulated IL-12 p40 production and down-regulated TNF-alpha production by stimulated macrophages; on the other hand, F.t. infection did not affect the production of IL-8, IL-6, MCP-5, and RANTES by stimulated macrophages.
6049 20495560 Here we demonstrate that cysteine protease-induced T(H)2 responses occur via 'cooperation' between migratory dermal dendritic cells (DCs) and basophils positive for interleukin 4 (IL-4).
6050 20495560 ROS orchestrated T(H)2 responses by inducing oxidized lipids that triggered the induction of thymic stromal lymphopoietin (TSLP) by epithelial cells mediated by Toll-like receptor 4 (TLR4) and the adaptor protein TRIF; by suppressing production of the T(H)1-inducing molecules IL-12 and CD70 in lymph node DCs; and by inducing the DC-derived chemokine CCL7, which mediated recruitment of IL-4(+) basophils to the lymph node.
6051 20511554 In this paper, we describe a new method for preparation of human dendritic cells (DCs) that secrete bioactive IL-12(p70) using synthetic immunostimulatory compounds as TLR7/8 agonists.
6052 20511554 They also had excellent capacity to activate NK cells, effectively polarized CD4(+) and CD8(+) T cells to secrete IFN-gamma and to induce T cell-mediated cytotoxic function.
6053 20525895 The release of IFN-gamma and IL-12, the signature cytokines of Th1 responses, was enhanced by V-Oka but blocked by virulent VZV.
6054 20525895 V-Oka and virulent VZV efficiently synergized with CD40L, eliminating the possibility that CD40 signaling was a target of VZV-associated immune evasion.
6055 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.
6056 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.
6057 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.
6058 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.
6059 20545626 OmC2 affected the function of antigen-presenting mouse dendritic cells by reducing the production of the pro-inflammatory cytokines tumour necrosis factor alpha and interleukin-12, and proliferation of antigen-specific CD4+ T-cells.
6060 20548030 To focus on the consequences of Treg deficiency confined to the skin, we generated mixed CCR4(KO) FoxP3(KO) bone marrow (CCR4/FoxP3) chimeras in which skin, but not other tissues or central lymphoid organs, lack Treg.
6061 20548030 Levels of the antiviral cytokines, type I and II IFNs and IL-12, were reduced, whereas expression of the proinflammatory cytokines, IL-6, IL-10, TGF-beta, and IL-23, was increased.
6062 20548030 Importantly, infection of CCR4/FoxP3 chimeras by a noncutaneous route (i.p.) induced immune responses comparable to controls.
6063 20548033 We asked whether the efficacy of dendritic cell (DC) vaccination with the renal cell carcinoma Ags MAGE-A9 (MAGE9) and G250 could be strengthened by covaccination with the renal cell carcinoma autoantigen GOLGA4.
6064 20548033 Autoantigen covaccination significantly strengthened tumor Ag-specific CD4(+) and CD8(+) T cell expansion, particularly in peptide-loaded DC-vaccinated mice.

6082 20601076 Mice vaccinated with parasite ribosomal proteins purified from Leishmania infantum plus saponin showed a specific production of IFN-γ, IL-12 and GM-CSF after in vitro stimulation with L. infantum ribosomal proteins.
6083 20601076 In both models, protection was correlated to an IL-12-dependent production of IFN-γ by CD4(+) and CD8(+) T cells that activate macrophages for the synthesis of NO.
6084 20601076 In the protected mice a decrease in the parasite-mediated IL-4 and IL-10 responses was also observed.
6085 20631332 Our results revealed that poly(anhydride) NPs also act as agonists of various Toll-like receptors (TLRs) (TLR2, -4, and -5), triggering a Th1-profile cytokine release (gamma interferon [IFN-gamma], 478 pg/ml versus 39.6 pg/ml from negative control; interleukin-12 [IL-12], 40 pg/ml versus 7.2 pg/ml from negative control) and, after incubation with dendritic cells, inducing a 2.5- to 3.5-fold increase of CD54 and CD86 costimulatory molecule expression.

6106 20668140 Our evaluation of immune competence, including gamma interferon (IFN-gamma) and interleukin-12 (IL-12) signaling, found no evidence of deficiency.
6107 20679438 Both gamma interferon (IFN-γ)- and interleukin 17 (IL-17)-secreting CD4(+) T cells have been identified in subjects with latent TB infection and during experimental Mycobacterium tuberculosis infection, but the contribution of Th17 cells to protective immunity is unclear.
6108 20679438 To examine their protective effects in vivo, we transferred mycobacterium-specific IL-17- and IFN-γ-secreting CD4(+) T cells isolated from M. tuberculosis BCG-immunized IL-12p40(-/-) and IFN-γ(-/-) or wild-type mice, respectively, into M. tuberculosis-infected IL-12p40(-/-) or RAG(-/-) mice.
6109 20679438 In the absence of IL-12 and IL-23, neither IL-17-secreting (Th17) nor IFN-γ-secreting (Th1) BCG-specific T cells expanded or provided protection against M. tuberculosis.
6110 20679438 In RAG(-/-) recipients with an intact IL-12/IL-23 axis, both Th17 and Th1 cells were activated and induced significant protection against M. tuberculosis.
6111 20679438 Both gamma interferon (IFN-γ)- and interleukin 17 (IL-17)-secreting CD4(+) T cells have been identified in subjects with latent TB infection and during experimental Mycobacterium tuberculosis infection, but the contribution of Th17 cells to protective immunity is unclear.

6113 20679438 In the absence of IL-12 and IL-23, neither IL-17-secreting (Th17) nor IFN-γ-secreting (Th1) BCG-specific T cells expanded or provided protection against M. tuberculosis.
6114 20679438 In RAG(-/-) recipients with an intact IL-12/IL-23 axis, both Th17 and Th1 cells were activated and induced significant protection against M. tuberculosis.
6115 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.
6116 20683901 We find that this vaccine enhances the proliferation of CD4(+) Th17 cells, which contrasts with the highly polarized Th1 response caused by L. major alone; the Th17 response is dependent upon release of vaccine-induced IL-6.
6117 20683901 Neutralization of IFN-gamma and, in particular, IL-17 caused increased parasite burdens in Lm/CpG-vaccinated mice.
6118 20683901 IL-17R-deficient Lm/CpG-vaccinated mice develop lesions, and display decreased IL-17 and IFN-gamma, despite normal IL-12, production.
6119 20685940 Unique Th1/Th2 phenotypes induced during priming and memory phases by use of interleukin-12 (IL-12) or IL-28B vaccine adjuvants in rhesus macaques.
6120 20685940 To that end, we have employed interleukin-12 (IL-12) and IL-28B as adjuvants for DNA vaccination of rhesus macaques.
6121 20685940 Moreover, analysis 3 months after the final immunization revealed the activity of the IL-12 adjuvant to be short lived, while the IL-28B adjuvant continued to exert its influence on the immune system.
6122 20685940 Unique Th1/Th2 phenotypes induced during priming and memory phases by use of interleukin-12 (IL-12) or IL-28B vaccine adjuvants in rhesus macaques.

6127 20685940 Moreover, analysis 3 months after the final immunization revealed the activity of the IL-12 adjuvant to be short lived, while the IL-28B adjuvant continued to exert its influence on the immune system.
6128 20702656 We found that both Plasmodium falciparum MIF (PfMIF) and Plasmodium vivax MIF (PvMIF) levels in patients were positively correlated with parasitemia, tumor necrosis factor alpha, interleukin-10 (IL-10), and monocyte chemoattractant protein 1 but were not correlated with transforming growth factor β1 and IL-12.
6129 20702656 Moreover, multiple stepwise regression analysis also showed that parasitemia, IL-10, and HuMIF expression were significant predictors of Plasmodium MIF production.
6130 20732465 Increased frequency of IL-10(+) monocytes was observed at day 15 and day 30, and decreased percentage of IL-4(+) NK-cells were detected at day 7, day 15 and day 30.
6131 20732465 Time-dependent and oscillating cytokine pattern was observed in CD4(+) T-cells, with low percentage of IL-12(+), IL-4(+) and IL-10(+) cells at day 7 and increased frequency of TNF-α(+) cells at day 15 besides IFN-γ(+) and IL-5(+) cells at day 15 and day 30.
6132 20732465 Later changes with increased percentage of IL-12(+) and IL-5(+)CD8(+) T-cells were observed at day 30.
6133 20738198 All tachyzoite and antigen preparations at high doses stimulated high levels of interleukin (IL) -12, interferon (IFN) -gamma, and tumor necrosis factor (TNF) -alpha, except for heat-killed tachyzoites and sNcAg, which induced moderate level of IL-12 and very low levels of IFN-gamma and TNF-alpha.
6134 20738198 In general, whole N. caninum tachyzoites were more effective in inducing IL-12, IFN-gamma, and TNF-alpha than the lysate antigen preparations.
6135 20738198 It appears that the heat-killed N. caninum tachyzoites were less potent in eliciting IFN-gamma or IL-10, but more effective in inducing IL-4.
6136 20738198 All tachyzoite and antigen preparations at high doses stimulated high levels of interleukin (IL) -12, interferon (IFN) -gamma, and tumor necrosis factor (TNF) -alpha, except for heat-killed tachyzoites and sNcAg, which induced moderate level of IL-12 and very low levels of IFN-gamma and TNF-alpha.
6137 20738198 In general, whole N. caninum tachyzoites were more effective in inducing IL-12, IFN-gamma, and TNF-alpha than the lysate antigen preparations.
6138 20738198 It appears that the heat-killed N. caninum tachyzoites were less potent in eliciting IFN-gamma or IL-10, but more effective in inducing IL-4.
6139 20739505 Recombinant adenovirus or DNA vaccines encoding herpes simplex virus type 1 (HSV-1) glycoprotein D (gD) genetically fused to human papillomavirus type 16 (HPV-16) oncoproteins (E5, E6, and E7) induce antigen-specific CD8(+) T-cell responses and confer preventive resistance to transplantable murine tumor cells (TC-1 cells).
6140 20739505 In the present report, we characterized some previously uncovered aspects concerning the induction of CD8(+) T-cell responses and the therapeutic anticancer effects achieved in C57BL/6 mice immunized with pgD-E7E6E5 previously challenged with TC-1 cells.
6141 20739505 Concerning the characterization of the immune responses elicited in mice vaccinated with pgD-E7E6E5, we determined the effect of the CD4(+) T-cell requirement, longevity, and dose-dependent activation on the E7-specific CD8(+) T-cell responses.
6142 20739505 Mice challenged with TC-1 cells and then immunized with three doses of pgD-E7E6E5 elicited CD8(+) T-cell responses, measured by intracellular gamma interferon (IFN-γ) and CD107a accumulation, to the three HPV-16 oncoproteins and displayed in vivo antigen-specific cytolytic activity, as demonstrated with carboxyfluorescein diacetate succinimidyl ester (CFSE)-labeled target cells pulsed with oligopeptides corresponding to the H-2D(b)-restricted immunodominant epitopes of the E7, E6, or E5 oncoprotein.
6143 20739505 In addition, coadministration of pgD-E7E6E5 with DNA vectors encoding pGM-CSF or interleukin-12 (IL-12) enhanced the therapeutic antitumor effects for all mice challenged with TC-1 cells.
6144 20800114 We show that a short peptide, named Hp91, whose sequence corresponds to an area within the endogenous molecule high mobility group box (HMGB1) protein 1 potentiates cellular immune responses to peptide antigen and cellular and humoral immune responses to protein antigen in vivo.
6145 20800114 Hp91 promoted the in vivo production of the immunomodulatory cytokines, IFN-γ, TNF-α, IL-6, and IL-12 (p70), as well as antigen-specific activation of CD8+ T cells.
6146 20800630 Furthermore, intravenous administration of Ad35 vectors in WT and CD46TG mice resulted in higher levels of serum interleukin (IL)-6 and IL-12 compared with administration of Ad5F35 vectors, which exhibited almost mock-transduced levels of these inflammatory cytokines.
6147 20811496 Production of TNF-alpha, IL-12(p40) and IL-17 can discriminate between active TB disease and latent infection in a West African cohort.
6148 20855390 Patients with interleukin 12 (IL-12)p40 or IL-12 receptor β1 (IL12Rβ1) deficiencies are prone to develop infections caused by mycobacteria and salmonella; other infections have only been rarely observed.
6149 20855616 In the present study, we demonstrate that virus-associated RNAs (VA-RNAs), which are small RNAs transcribed by RNA polymerase III, induce the production of type I IFN (IFN-α and IFN-β), but they do not induce the production of inflammatory cytokines (IL-6 and IL-12), in mouse embryonic fibroblasts (MEFs) and granulocyte-macrophage colony-stimulating factor-generated bone marrow-derived dendritic cells (GM-DCs).
6150 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).
6151 20863822 There was a significant increase in stimulatory cytokines gene expression (IL-2, IL-12, IL-15, IL-18 and IFN-γ).
6152 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.
6153 20926697 Simultaneous measurement of antigen-stimulated interleukin-1 beta and gamma interferon production enhances test sensitivity for the detection of Mycobacterium bovis infection in cattle.
6154 20926697 In order to identify cytokines that may be useful as candidates for inclusion in diagnostic tests for Mycobacterium bovis infection in cattle, we compared the levels of gamma interferon (IFN-γ), interleukin 1β (IL-1β), IL-4, IL-10, IL-12, macrophage inflammatory protein 1β (MIP-1β), and tumor necrosis factor alpha (TNF-α) in whole-blood cultures from tuberculosis (TB) reactor animals or TB-free controls following stimulation with M. bovis-specific antigens (purified protein derivative from M. bovis [PPD-B] or ESAT-6/CFP-10).
6155 20937847 The regulation of Th1 responses by the p38 MAPK.
6156 20937847 IL-12 production was also increased in macrophages treated with small interfering RNA to limit p38α expression, and in macrophages deficient in MKK3, a kinase upstream of p38.
6157 20937847 The increase in IL-12 production following MAPK/p38 inhibition appears to be due to enhanced IL-12 (p40) mRNA stability.
6158 20960074 PDT-generated antigens further purified by acid elution had the greatest stimulatory effect on DCs based on the elevated serum IL-12 and TNF-α levels and decreased serum IL-10 levels.
6159 21039466 Immature MoDCs were generated by incubating peripheral blood monocytes with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4.
6160 21039466 MoLCs showed a lower expression of CD83, CD86, HLA-DR and CCR7 compared with MoDCs, regardless of their maturational status.
6161 21039466 Both immature and mature MoLCs secreted higher quantities of IL-23 compared with MoDCs and this finding correlated with a higher secretion of IL-17 in co-culture of MoLCs with allogeneic CD4(+) T cells.
6162 21039466 Mature MoLCs, which produced higher levels of IL-12 and lower levels of IL-10 compared with mature MoDCs, were more potent at inducing interferon-γ (IFN-γ) production by CD4(+) T cells in the co-culture system.
6163 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.
6164 21039737 There were no statistical changes for CD4/CD8 ratios, IL-4 and CD69 levels between the three-vaccine immunized groups.
6165 21085613 PLY synergized with TLR agonists to enhance secretion of the proinflammatory cytokines IL-12, IL-23, IL-6, IL-1β, IL-1α and TNF-α by DC and enhanced cytokines including IL-17A and IFN-γ by splenocytes.
6166 21085613 IL-1β plays a key role in promoting IL-17A and was previously shown to mediate protection against pneumococcal infection.
6167 21159924 The IL-12 production was a consequence of the ligation of those recombinant proteins with Toll-like receptor 2.
6168 21159924 The M. tuberculosis-derived and M. leprae-derived recombinant proteins activated naïve T cells of both CD4 and CD8 subsets, but M. tuberculosis-derived proteins were superior to M. leprae-derived proteins and fusion proteins were superior to MMP, regardless of the origin of the protein.
6169 21159924 Memory-type CD4(+) T cells obtained from BCG-vaccinated healthy individuals seem to be primed with MMP-MTB by the vaccination, and both M. tuberculosis-derived recombinant proteins produced perforin-producing CD8(+) T cells from memory-type CD8(+) T cells.
6170 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.
6171 21173782 Results showed that TLR2(-/-), TLR4(-/-)and TLR7(-/-) mice survived ECTV infection whereas MyD88(-/-) and TLR9(-/-)mice, in contrast, were highly susceptible.
6172 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.
6173 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.
6174 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.
6175 21181148 The vaccinated groups also showed increased levels of Th1 cytokines interleukin (IL)-2, IL-12, and IFN-γ.
6176 21189473 IL-12 gene therapy-induced CD8(+) T cells directly recognized HLA-A2(+) pericytes and VEC flow-sorted from B16 tumor lesions based on interferon (IFN)-γ secretion and translocation of the lytic granule-associated molecule CD107 to the T cell surface after coculture with these target cells.
6177 21209158 We describe the development and validation of a microsphere-based assay for three commonly analyzed domestic cat cytokines (gamma interferon, interleukin-10, and interleukin-12/interleukin-23 p40) using reagents from commercially available ELISAs.
6178 21209158 The validated lower and upper quantitation limits were 31 and 1,000 pg/ml for gamma interferon, 63 and 2,000 pg/ml for interleukin-10, and 39 and 625 pg/ml for interleukin-12/interleukin-23 p40.

6181 21228885 In this study, we demonstrated that intratumoral (i.t.) injection of MSCs expressing modified interleukin-12 (MSCs/IL-12M) exhibited stronger tumor-specific T-cell responses and antitumor effects as well as more sustained expressions of IL-12 and interferon (IFN)-γ in both sera and tumor sites than did IL-12M-expressing adenovirus (rAd/IL-12M) in mice bearing both solid and metastatic tumors.
6182 21228885 Subcutaneous (s.c.) injection of MSCs/IL-12M at contralateral site of tumor exhibited similar levels of serum IL-12 and IFN-γ as i.t. injection, but much weaker antitumor effects in both B16F10 melanoma and TC-1 cervical cancer models than i.t. injection.
6183 21228885 In this study, we demonstrated that intratumoral (i.t.) injection of MSCs expressing modified interleukin-12 (MSCs/IL-12M) exhibited stronger tumor-specific T-cell responses and antitumor effects as well as more sustained expressions of IL-12 and interferon (IFN)-γ in both sera and tumor sites than did IL-12M-expressing adenovirus (rAd/IL-12M) in mice bearing both solid and metastatic tumors.
6184 21228885 Subcutaneous (s.c.) injection of MSCs/IL-12M at contralateral site of tumor exhibited similar levels of serum IL-12 and IFN-γ as i.t. injection, but much weaker antitumor effects in both B16F10 melanoma and TC-1 cervical cancer models than i.t. injection.
6185 21236236 Compared to the mice unvaccinated or vaccinated with empty plasmid, CD11c(+) cells at the dLN from naïve B6 mice expressed prominent IL-12 mRNA after the T.g.HSP70 gene vaccine.
6186 21236236 Also, CD4(+) cells at the dLN from the mice expressed prominent interferon-γ, but not IL-4 or IL-17, mRNA at a maximum level at day 5 following vaccination.
6187 21236236 This T.g.HSP70 gene vaccine-induced DC activation and Th1 polarization were also observed in TRIF-deficient mice, but not MyD88-deficient mice with B6 background indicating the involvement of TLR4/MyD88 signal transduction cascade in the vaccine effects with T.g.HSP70 gene.
6188 21236236 The T.g.HSP70 gene vaccine (twice at a 2-week interval) has been shown to limit T. gondii loads in the mesenteric LN of WT, TLR2-deficient and TRIF-deficient mice, but neither TLR4-deficient nor MyD88-deficient mice, at an acute phase of toxoplasmosis.
6189 21236236 The T.g.HSP70 gene vaccine also limited cyst number in the brains of WT, TLR2-deficient and TRIF-deficient mice, but not TLR4-deficient mice at a chronic phase of toxoplasmosis.
6190 21245658 The cytokine (IL-4, IL-6, IL-10, IL-12 and IL-23) profiles of DCs induced by individual TLR agonists have been evaluated.
6191 21245658 Using various mitogen-activated protein kinase (MAPK) inhibitors (c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK) and p38 MAPK) we have demonstrated the importance of p38 MAPK and ERK signaling pathways in IL-12p70 and IL-12p40 production in DCs induced by TLR stimulation, whereas the JNK pathway appeared to have a negative regulatory role on cytokine production in DCs stimulated with certain TLR agonists.
6192 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.
6193 21316756 In addition, Epi-1 modulated the expressions of immune-responsive genes like interleukin (IL)-6, IL-10, MCP-1, tumor necrosis factor-α, interferon-γ and IL-12, and elevated the levels of anti-JEV-neutralizing antibodies in the serum.
6194 21369988 A combination of RENCA lysates and AbOmpA up-regulated the surface expression of co-stimulatory molecules, CD80 and CD86, and the antigen presenting molecules, major histocompatibility (MHC) class I and class II, in DCs.
6195 21369988 DCs pulsed with a combination of CA9 and AbOmpA effectively secreted IL-12 but not IL-10.
6196 21369988 DCs pulsed with CA9 and AbOmpA elicited the secretion of interferon-γ and IL-2 in T cells.
6197 21374318 Overall, CpG DNA induces a Th1 like pattern of cytokine production dominated by IL-12 and IFN-γ, with little secretion of Th2 cytokines (4,5).
6198 21412284 We have found that coinfection of HSV-IL-2-infected mice with recombinant viruses expressing IL-12p35, IL-12p40 or IL-12p35+IL-12p40 did not block the CNS demyelination, and that coinfection with a recombinant virus expressing interferon (IFN)-γ exacerbated it.
6199 21412284 In contrast, coinfection with a recombinant virus expressing IL-4 reduced demyelination, whereas coinfection of HSV-IL-2-infected mice with a recombinant HSV-1 expressing the IL-12 heterodimer (HSV-IL-12p70) blocked the CNS demyelination in a dose-dependent manner.
6200 21412284 Injection of mice with IL-12p35 DNA, IL-12p40 DNA, IL-12p35+IL-12p40 DNA or IL-23 DNA did not have any effect on HSV-IL-2-induced demyelination, whereas injection of IL-27 DNA increased the severity of the CNS demyelination in the HSV-IL-2-infected mice.
6201 21412284 This study demonstrates for the first time that IL-12p70 can block HSV-IL-2-induced CNS demyelination and that IL-35 can also reduce this demyelination, whereas IFN-γ and IL-27 exacerbated the demyelination in the CNS of the HSV-IL-2-infected mice.

6222 21439674 These developments have implemented two major innovations in DC preparation: first, young DCs are prepared within 3 days and, second, the DCs are matured with the help of Toll-like receptor agonists, imbuing them with the capacity to produce bioactive IL-12 (p70).
6223 21439674 Based on phenotype, chemokine-directed migration, facility to process and present antigens, and stimulatory capacity to polarize Th1 responses in CD4+ T cells, induce antigen-specific CD8+ CTL and activate natural killer cells, these young mDCs display all the important properties needed for initiating good antitumor responses in a vaccine setting.
6224 21445524 In addition, a single vaccine dose consisting of the co-administration of pgD-E7E6E5 and the vector encoding interleukin-12 or granulocyte-macrophage colony-stimulating factor further enhanced the therapeutic anti-tumor effects and conferred protection to 60 and 50% of the vaccinated mice, respectively.
6225 21463625 DCs were generated from peripheral blood monocytes with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor (GM-CSF).
6226 21463625 Compared to DCs treated with E7 in a 2-D culture model, the expression of co-stimulatory molecules CD80 and CD40 were significantly increased in the 3-D model (p<0.05), and a remarkable increase of IL-12 p70 was observed.
6227 21468000 Optimizing DC vaccination by combination with oncolytic adenovirus coexpressing IL-12 and GM-CSF.
6228 21468000 To overcome these obstacles and enhance the efficiency of DC vaccination, we generated interleukin (IL)-12- and granulocyte-macrophage colony-stimulating factor (GM-CSF)-coexpressing oncolytic adenovirus (Ad-ΔB7/IL12/GMCSF) as suitable therapeutic adjuvant to eliminate immune suppression and promote DC function.
6229 21468000 By treating tumors with Ad-ΔB7/IL12/GMCSF prior to DC vaccination, DCs elicited greater antitumor effects than in response to either treatment alone.
6230 21468000 This result was associated with upregulation of CC-chemokine ligand 21 (CCL21(+)) lymphatics in tumors treated with Ad-ΔB7/IL12/GMCSF.
6231 21468000 Moreover, the proportion of CD4(+)CD25(+) T-cells and vascular endothelial growth factor (VEGF) expression was decreased in mice treated with the combination therapy.
6232 21468000 Furthermore, combination therapy using immature DCs also showed effective antitumor effects when combined with Ad-ΔB7/IL12/GMCSF.

6269 21493800 Priming CD8+ T cells with dendritic cells matured using TLR4 and TLR7/8 ligands together enhances generation of CD8+ T cells retaining CD28.
6270 21493800 Maturation of DCs with lipopolysaccharide (LPS; TLR4) concurrently with R848 (TLR7/8) induced a heterogeneous population of DCs that produced high levels of IL12 p70.
6271 21493800 Compared with DCs matured with LPS or R848 alone, the DC population matured with both adjuvants primed CD8+ T-cell responses containing an increased proportion of antigen-specific T cells retaining CD28 expression.
6272 21493800 Priming with a homogenous subpopulation of LPS/R848-matured DCs that were CD83(Hi)/CD80+/CD86+ reduced this CD28+ subpopulation and induced T cells with an effector cytokine signature, whereas priming with the less mature subpopulations of DCs resulted in minimal T-cell expansion.
6273 21519830 Additionally, as we previously reported, IFN-γ-producing CD8(+) T cells act as "helper cells," supporting the ability of dendritic cells to produce interleukin-12 (IL-12)p70.
6274 21519830 Murine bone marrow-derived dendritic cells (DC) were pulsed with OVA(257-264) (SIINFEKL), which is an H-2Kb target epitope of EG7 [ovalbumin (OVA)-expressing EL4] cell lines, in the presence of SEA and SEB and were subcutaneously injected into naïve C57BL/6 mice.
6275 21593236 A significant downregulation of CXCR3 and IL-12 receptors (both TH1 markers) and a significant increase in the chemokine receptor CCR4 and, to a lesser extent, IL-4R (both TH2 markers) were found; a particularly marked increase was found in patients treated by combined therapy.
6276 21638126 LMW HA improved maturation of ex vivo generated DC, increased IL-12, decreased IL-10 production, and enhanced a MLR activity in vitro.
6277 21638126 Although TNF-α showed a similar capacity to mature DC, preconditioning of DC/TL with LMW HA increased their ability to migrate in vitro toward CCL19 and CCL-21 in a CD44- and a TLR4-independent manner; this effect was superior to Poly(I:C), LPS, or TNF-α and partially associated with an increase in the expression of CCR7.
6278 21669537 Francisella tularensis LVS-induced Interleukin-12 p40 cytokine production mediates dendritic cell migration through IL-12 Receptor β1.
6279 21669537 Three cytokines use the IL-12p40 cytokine subunit namely: IL-12p70 (IL-12-comprised of IL-12p40 and IL-12p35), IL-23 (comprised of the IL-12p40 and IL-23p19 subunits) and homodimeric IL-12p40 (IL-12(p40)(2)).
6280 21669537 Following activation, immature dendritic cells (DCs) upregulate the chemokine receptor Chemokine-C-Receptor 7 (CCR7), and migrate in response to homeostatic chemokines such as chemokine (C-C motif) ligand 19 (CCL19).

6283 21669537 Following activation, immature dendritic cells (DCs) upregulate the chemokine receptor Chemokine-C-Receptor 7 (CCR7), and migrate in response to homeostatic chemokines such as chemokine (C-C motif) ligand 19 (CCL19).
6284 21687419 We further found that pre-treatment of hiPSCs with ionizing radiation promotes the secretion of pro-inflammatory cytokines such as interleukin-1 alpha (IL-1α), IL-12, and IL-18.
6285 21752950 Most interesting, however, is the cytokine secretion profile of curdlan-stimulated MoDCs, since only curdlan induced significant higher expression levels of interleukin-1β (IL-1β), IL-6, IL-10, and IL-12/IL-23p40.
6286 21752952 The purpose of this study was to determine the degree of infiltration of different cell subpopulations (tissue dendritic macrophages, T-helper cells, cytotoxic T lymphocytes, monocytes, neutrophils, and B cells) and the expression of the cytokines interleukin-12 (IL-12) and tumor necrosis factor alpha (TNF-α) in inflamed and noninflamed resected tissues from Crohn's disease (CD) and non-CD patients.
6287 21799517 In c-Cbl-deficient dendritic cells, Toll-like receptor-induced expression of proinflammatory factors, such as interleukin-12, is increased, correlating with a greater potency of dendritic-cell-based vaccines against established tumours.
6288 21799517 In addition, c-Cbl deficiency reduces both p50 and p105 levels, which have been shown to modulate the stimulatory function of NF-κB.
6289 21802664 Synergy between TLR3 and IL-18 promotes IFN-γ dependent TRAIL expression in human liver NK cells.
6290 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.
6291 21813451 In this study, we identify Type I IFN and IL-12 as critical mediators of cross-priming induced by a TLR7 agonist-antigen conjugate.
6292 21813451 We demonstrate that TLR7-driven cross-priming requires both Type I IFN and IL-12.
6293 21813451 Collectively, the data show that a TLR7 agonist-antigen conjugate elicits CD8(+) T-cell responses by the coordinated recruitment and activation of both tissue-derived and lymphoid organ-resident DC subsets through a Type I IFN and IL-12 codependent mechanism.

6300 21856352 When the plasmid contained both motifs, transfected murine macrophage-like RAW264.7 cells showed markedly increased levels of mRNA for immune molecules of Th1 (IFN-α, IL-12) and Th17 (IL-17, IL-23 and IL-6) responses and for T cell co-stimulatory molecules (CD80 and CD86) but not for a Th2 response (IL-4 and IL-10).
6301 21901556 Use of Lactobacillus species to combat UTI is now giving modern concept of modern genitourinary vaccine with the facts that it not only maintains low pH of the genital area, produces hydrogen peroxide and hinders the growth of E. coli but also activates Toll-like receptor-2 (TLR2), which produces interleukin-10 (IL-10) and myeloid differentiation factor 88 (MyD88).
6302 21901556 E. coli activates TLR4, which is responsible for the activation of IL-12, extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK).
6303 21905505 Bacille Calmette-Guérin lymphadenitis and recurrent oral candidiasis in an infant with a new mutation leading to interleukin-12 receptor beta-1 deficiency.

6306 21905505 Interleukin-12 receptor beta1 (IL-12Rbeta1) deficiency is the most frequent genetic cause of MSMD.
6307 21907198 Additionally, levels of the Th1-associated cytokines IL-12(p40), TNF-α, and IFN-γ were significantly increased in the spleens of the BALB/c mice.
6308 21914064 The DNA of HBV S gene and the cDNA of the extracellular domain of human CD40 ligand were linked by cloning.
6309 21914064 Peripheral blood mononuclear cells (PBMC) from healthy adults were incubated and induced into dendritic cells (DC) in presence of granulocyte/macrophage colony-stimulating factor (GM-CSF) and interleukin-4(IL-4).
6310 21914064 We find that, compared with control groups, modification of DCs with HBV S-ecdCD40L fusion gene resulted in the activation of DCs with upregulated expression of immunologically important cell surface molecules (CD80, CD86 and HLA-DR) and proinflammatory cytokines (IL-12).
6311 21934655 Identification of molecular adjuvants to in vivo "modulate " DC to coordinately render improved Th1 and CD8 T cell immunity, and attenuated deleterious Treg effects, is a critical challenge.

6330 22052597 A total of 10 single nucleotide polymorphisms distributed in 6 genes (TNFRSF1A, IL12A, IL12B, IFNG, IL4, and IL10) were genotyped in 214 high-responders [hepatitis B surface antibody (anti-HBs) ≥1,000 mIU/ml] and 107 low-responders (anti-HBs: 10-99 mIU/ml).
6331 22052597 In addition, a significant gene-gene interaction was found: the frequency of the combined genotypes IL12A rs2243115 TT and IL12B rs17860508 CTCTAA/CTCTAA was significantly higher in the low-response group than in the high-response group (P = 0.008, odds ratio = 2.19, 95% confidence interval = 1.23-3.93).
6332 22052597 These findings suggest that polymorphisms in the IL12A and IL12B genes might play an important role jointly in determining the response to hepatitis B vaccination.

6339 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.
6340 22068049 The serum IgG2a levels induced by Gag p41-His-Ni-NCs (1 μg) were significantly higher than AH adjuvanted His-Gag p41.
6341 22068049 The Ni-NCs alone did not result in the elevation of systemic IL-12/p40 and CCL5/RANTES inflammatory cytokine levels upon subcutaneous administration in BALB/c mice.
6342 22068049 In conclusion, the proposed Ni-NCs can bind His-tagged proteins and have the potential to be used as antigen delivery system capable of generating strong antigen-specific antibodies at doses much lower than with aluminum-based adjuvant and causing no significant elevation of systemic pro-inflammatory IL-12/p40 and CCL5/RANTES cytokines.

6346 22072757 Furthermore, the γ(1)34.5 null mutant activates IκB kinase, which facilitates p65/RelA phosphorylation and nuclear translocation, resulting in DC maturation.
6347 22072757 This is mirrored by a higher level of interleukin-6 (IL-6) and IL-12 secretion by CD8(+) DCs than CD8(-) DCs.
6348 22072757 Remarkably, inhibition of p65/RelA phosphorylation or nuclear translocation in CD8(+) DCs disrupts protective immunity.
6349 22079980 The soluble L. donovani Ag stimulated PBMCs of cured/exposed and Leishmania patients to produce a mixed Thl/Th2-type cytokine profile, whereas rLelF-2 stimulated the production of IFN-γ, IL-12, and TNF-α but not IL-4 or IL-10.
6350 22079980 Further, rLelF-2 downregulated LPS-induced IL-10 as well as soluble L. donovani Ag-induced IL-4 production by Leishmania patient PBMCs.
6351 22079980 The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFN-γ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.

6355 22089247 The protective response mediated by the injection of primed DCs was characterized mainly by an increased production of gamma interferon (IFN-γ) and interleukin 12 (IL-12) and a reduction in IL-10 and IL-4 compared to those of infected mice that received saline or unprimed DCs.
6356 22101830 IL-23-dependent IL-17 drives Th1-cell responses following Mycobacterium bovis BCG vaccination.
6357 22101830 Here, in a model of Mycobacterium bovis Bacille Calmette-Guerin (BCG) vaccination in mice, we demonstrate that the dependence on IL-17 to drive Th1-cell responses is a host mechanism to overcome bacteria-induced IL-10 inhibitory effects.
6358 22101830 We show that BCG-induced prostaglandin-E2 (PGE2) promotes the production of IL-10 which limits Th1-cell responses, while simultaneously inducing IL-23 and Th17-cell differentiation.
6359 22101830 The ability of IL-17 to downregulate IL-10 and induce IL-12 production allows the generation of subsequent Th1-cell responses.
6360 22101830 Importantly, in the absence of IL-10, BCG-induced Th1-cell responses occur in an IL-17-independent manner.
6361 22101830 These novel data demonstrate a role for the IL-23/IL-17 pathway in driving Th1-cell responses, specifically to overcome IL-10-mediated inhibition and, furthermore, show that in the absence of IL-10, the generation of BCG-induced Th1-cell immunity is IL-17 independent.

6374 22158905 Immunotherapy with PI3K inhibitor and Toll-like receptor agonist induces IFN-γ+IL-17+ polyfunctional T cells that mediate rejection of murine tumors.
6375 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.
6376 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.

6401 22190395 In vivo profiling of 16 inflammatory cytokines in patients infected with the outbreak strain revealed a common profile of a remarkable gamma interferon (IFN-γ) induction together with elevated concentrations of tumor necrosis factor alpha (TNF-α), IL-6, IL-8, IL-10, and IL-15, but not IL-12, which was previously demonstrated as elevated in nontyphoidal Salmonella infections.
6402 22379063 Levels of IgG antibody, gamma interferon (IFN-γ), interleukin 2 (IL-2), IL-12, IL-4, and IL-10 were examined.
6403 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).

6409 22467649 Whereas sustained Akt activation severely impaired CD8 T cell memory and protective immunity, in vivo inhibition of Akt rescued SLECs from deletion and increased the number of memory CD8 T cells.
6410 22488274 We hypothesized that local injection of VRP-expressing interleukin-12 (IL-12) at the site of injections of VRP-based cancer vaccines would enhance the tumor-antigen-specific T cell and antibody responses and antitumor efficacy.
6411 22488274 Mice were immunized with VRP encoding the human tumor-associated antigen, carcinoembryonic antigen (CEA) (VRP-CEA(6D)), and VRP-IL-12 was also administered at the same site or at a distant location.
6412 22504412 We speculate that IL12RB1 polymorphisms may affect IL-12 and IL-23 binding and downstream effects, which are critical cytokines in the CMI response to measles vaccine.
6413 22539564 Interleukin-12 (IL-12)/IL-10 ratio as a marker of disease severity in Crimean-Congo hemorrhagic fever.
6414 22561311 We have previously reported that defined cocktails of cytokines, involving TNFα and IFNγ, induce mature type-1 polarized DCs (DC1s) which produce strongly elevated levels of IL-12 and CXCL10/IP10 upon CD40 ligation compared to "standard" PGE₂-matured DCs (sDCs; matured with IL-1β, IL-6, TNFα, and PGE₂) and show higher CTL-inducing activity.
6415 22561311 Restimulated lymphocytes, or their culture supernatants, enhanced the maturation status of immature (i)DCs, elevating their expression of CD80, CD83 and CCR7, and the ability to produce IL-12p70 and CXCL10 upon subsequent CD40 ligation.
6416 22615208 This fusion protein formed oligomers/aggregates that led to activation of STAT-1 and IFN regulatory factor-3 in human macrophages, indicating a type I IFN response, resulting in NO, IL-12, and IL-6 induction.

6434 22684724 This strain (designated GIDIFN) was able to modulate immune responses following systemic inoculation by upregulating the production of inflammatory mediators (IL-6 and IL-12) and anti-bacterial effector molecules (nitric oxide; NO).
6435 22720235 While T cells loaded with a class I-restricted peptide induced proliferation but not effector differentiation of antigen-specific CD8 T cells, injection of T cells co-pulsed with αGC strongly induced IFNγ and Granzyme B expression in T cells and complete lysis of target cells in vivo.
6436 22720235 Of note, the generation of this cytotoxic T cell response was independent of IL-4, IFNγ, IL-12, IL-21 and costimulation.
6437 22750042 The interleukins (ILs) such as IL-2 and IL-12 were added to the vaccine formulation to further enhance the immune response.

6445 23000222 The cytokine profile varied at various time points after immunization and challenge, which showed down regulation of Th2 cytokines (IL-4, IL-10) and up-regulation of proinflammatory cytokines (IL-12 and IL-17).
6446 23144752 The relative expression of IL-12 and INF-γ was significantly higher in the small intestine of mice treated with V cells, while an increase in IL-5, IL-13 and TNF-α expression was only detected in mice treated with HK cells.
6447 23233675 Interestingly, knockdown of miR-99b in DCs significantly up-regulated proinflammatory cytokines such as IL-6, IL-12, and IL-1β.

6461 23333935 In situ Ad.Flagrp170 therapy provokes systemic activation of CTLs that recognize several antigens naturally expressing in melanoma (e.g., gp100/PMEL and TRP2/DCT).
6462 23333935 Antibody neutralization assays show that IL-12 and IFN-γ are essential for the Flagrp170-elicited antitumor response, which also involves CD8(+) T cells and natural killer cells.
6463 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.
6464 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.
6465 23464355 Interleukin-27 (IL-27) is a heterodimeric cytokine of the IL-12 family that is produced primarily by antigen-presenting cells and is immunosuppressive toward a variety of immune cell types.
6466 23464355 We show that IL-27 gene expression is elevated in cord blood-derived macrophages relative to macrophages originating from healthy adults.
6467 23464355 We also evaluated the duration over which elevated IL-27 gene expression may impact immune responses in mice.
6468 23464355 Age-dependent analysis of IL-27 gene expression indicated that levels of IL-27 remained significantly elevated throughout infancy and then declined in adult mice.
6469 23464355 Neutralization of IL-27 in neonatal macrophages improved the ability of these cells to limit bacterial replication.
6470 23464355 Moreover, neutralization of IL-27 during incubation with the Mycobacterium bovis bacillus Calmette-Guérin vaccine augmented the level of interferon-γ elicited from allogeneic CD4+ T lymphocytes.
6471 23464355 This suggests that blocking IL-27 during vaccination and infection may improve immune responses in newborn and infant populations.

6477 23486418 Markers of innate immune activation (lipopolysaccharide [LPS] and lipopolysaccharide-binding protein [LBP]) were significantly lower in ETB than in PTB children.
6478 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.
6479 23508902 Peripheral blood lymphocyte counts indicated lymphopenia and inverted ratios of CD4(+) to CD8(+) cells.
6480 23508902 Cytokine analysis showed that the levels of serum IL-6, IL-10, and IFN-r continued to increase, whereas the levels of IL-12 and TNFs decreased during the clinical course.

6500 23522926 Interleukin-27 (IL-27), a novel IL-6/IL-12 family cytokine, plays an important role in the early regulation of Th1 responses.
6501 23522926 The cytokine IL-27 can exert a variety of immune-regulatory functions including cytotoxic T lymphocyte (CTL), CD4+, CD8+ T lymphocytes activation and interferon-γ (IFN-γ) production.
6502 23522926 Lewis lung cancer cell LL/2 transfected with the DOTAP:cholesterol cationic liposome could express the mouse IL-27 (mIL-27) gene at a relative high level.
6503 23522926 Both CD4+ and CD8+ T lymphocytes were significantly elevated in these mice vaccinated with LL/2-mIL-27 cell vaccine.

6513 23536633 This was associated with higher rates of apoptosis in precursor cells and increased expression of cleaved caspase-3 and BCL-xL and downregulation of cyclin B1.
6514 23536633 Further, blockade of fatty-acid synthesis decreased DC expression of MHC class II, ICAM-1, B7-1, and B7-2 but increased their production of selected proinflammatory cytokines including IL-12 and MCP-1.
6515 23536633 Accordingly, inhibition of fatty-acid synthesis enhanced DC capacity to activate allogeneic as well as Ag-restricted CD4(+) and CD8(+) T cells and induce CTL responses.
6516 23536633 We found that inhibition of fatty-acid synthesis resulted in elevated expression of numerous markers of ER stress in humans and mice and was associated with increased MAPK and Akt signaling.

6522 23555672 C57BL/6 mice immunized with TcVac3 elicited a strong antigen-specific, high-avidity, trypanolytic antibody response (IgG2b>IgG1); and a robust antigen- and Tc-specific CD8(+)T cell response with type-1 cytokine (IFN-γ(+)TNF-α>IL-4(+)IL-10) and cytolytic effector (CD8(+)CD107a(+)IFN-γ(+)Perforin(+)) phenotype.
6523 23555672 Co-delivery of IL-12 and GMCSF cytokine adjuvants didn't enhance the TcVac3-induced resistance to T. cruzi.
6524 23555672 In chronic phase, vaccinated/infected mice exhibited a significant decline (up to 70%) in IFN-γ(+)CD8(+)T cells, a predominance of immunoregulatory IL-10(+)/CD4(+)T and IL10(+)/CD8(+)T cells, and presented undetectable tissue parasitism, inflammatory infiltrate, and fibrosis in vaccinated/infected mice.
6525 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.
6526 23631767 Cytokine production from BMDCs treated with the AuNP-Es revealed that only Rod-E-treated cells produced significant levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18), indicating that Rod-Es activated inflammasome-dependent cytokine secretion.
6527 23631767 Meanwhile, Sphere40-Es and Cube-Es both significantly induced inflammatory cytokine production, including tumor necrosis factor-α (TNF-α), IL-6, IL-12, and granulocyte macrophage colony-stimulating factor (GM-CSF).

6529 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.
6530 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.
6531 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.
6532 23681283 We investigated whether HDAC inhibitors augmented antitumor effect of indoleamine 2,3 dioxygenase (IDO) shRNA.

6575 23877655 BM-derived DCs infected by ad-shRNA-SOCS1 were pulsed with the HPV16mE7 protein and then were transfused into mouse models bearing TC-1 tumor cells expressing HPV16 E6/E7.
6576 23877655 IFN-γ, cytokine (TNF-α, IL-12, IL-6) expression, anti-E7 antibody and cytotoxic T lymphocyte (CTL) levels were measured.
6577 23886112 These approaches have included: (1) the use of IL-17A and IL-17F-deficient mice, (2) specific antibodies directed against IL-17, (3) an IL-17 vaccine, (4) methods to block the IL-17 receptor and (5) small-molecule inhibitors of IL-17.
6578 23886112 This paper will review the preclinical results using various pharmacological approaches [specific IL-17 antibodies, an IL-17 receptor fusion protein, IL-12/IL-23 p40 subunit and IL-17 vaccine approaches, as well as a small molecule inhibitor (Vidofludimus)] to inhibit IL-17 in animal models of IBD.
6579 23886112 Finally, future pharmacological approaches of interest will be discussed, such as: (1) Retinoic acid receptor-related orphan nuclear receptor gamma t (Rorγt) antagonists, (2) Retinoic acid receptor alpha (RARα) antagonists, (3) Pim-1 kinase inhibitors and (4) Dual small-molecule inhibitors of NF-κB and STAT3, like synthetic triterpenoids.
6580 23891392 During vaccination of MHC class I deficient beta-2 microglobulin knockout mice (β2M(-/-)) with an IL-12/αIL-4 Th1 biasing procedure, all of the mice died.

6584 23898209 Mucosa-associated invariant T (MAIT) cells are "innate" T cells that express an invariant T-cell receptor α-chain restricted by the nonclassical MHC class I molecule MHC-related protein 1 (MR1).
6585 23898209 Mechanistic studies showed that MAIT cells required both MR1 and IL-12 40 kDa subunit (IL-12p40) signals from infected antigen presenting cells to control F. tularensis LVS intracellular growth.
6586 23898209 Importantly, pulmonary F. tularensis LVS infection of MR1-deficient (MR1(-/-)) mice, which lack MAIT cells, revealed defects in early mucosal cytokine production, timely recruitment of IFN-γ-producing CD4(+) and CD8(+) T cells to the infected lungs, and control of pulmonary F. tularensis LVS growth.

6607 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.
6608 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.
6609 23928481 Our previous study established that Poly-ICLC is the most potent individual maturation stimulus for human DCs as assessed by an upregulation of CD83 and CD86, induction of interleukin-12 (IL-12), tumor necrosis factor (TNF), interferon gamma-induced protein 10 (IP-10), interleukmin 1 (IL-1), and type I interferons (IFN), and minimal interleukin 10 (IL-10) production.
6610 23928481 After incubation, the lymphocytes are washed off and the adherent monocytes are cultured for 5 days in the presence of interleukin-4 (IL-4) and granulocyte macrophage-colony stimulating factor (GM-CSF) to differentiate to immature DCs.
6611 23933281 Three days after the treatment, peritoneal macrophages were collected, plated and production of the cytokines IL-10 and IL-12 was evaluated in supernatants of the cultures after 24 h.
6612 23952477 Autosomal recessive interleukin-12 receptor β1 (IL-12Rβ1) deficiency has been described as the most common cause of Mendelian susceptibility to mycobacterial disease (MSMD), characterized by clinical disease due to weakly virulent mycobacteria such as Bacille Calmette-Guérin (BCG) vaccines and environmental mycobacteria (EM) in children who are normally resistant to most infectious agents.

6614 23969885 An evaluation is made of the efficacy of both preventive and therapeutic antitumor vaccines against murine melanoma, using C57BL/6 mice and irradiated B16 tumor cells expressing granulocyte and macrophage colony-stimulating factor (GM-CSF), interleukin-12 (IL-12) or both.
6615 23969885 The therapeutic vaccination strategies resulted in significantly delayed tumor growth, mainly using B16 cells producing GM-CSF+IL-12 cytokines, with 70% tumor growth inhibition (P<0.001)-although none of the animals reached overall survival.

6633 24022478 Macrophages play an important role in attempt to eliminate mycobacteria, via production of cytokines, including interleukin-1, and interleukin-12.
6634 24022478 Our aim was to estimate serum levels of interleukin-1β and interleukin-12, in leprosy, and to assess the impact of previous BCG vaccination on their levels.
6635 24022478 Serum interleukin-1β and interleukin-12 p70 were estimated in 43 leprotic patients and 43 controls by enzyme-linked immunosorbent assay.

6642 24027025 Moreover, HbR-DNA immunization stimulated the production of protective cytokines like interferon-γ (IFN-γ), interleukin-12 (IL-12), and tumor necrosis factor-α (TNF-α) with concomitant down-regulation of disease-promoting cytokines like IL-10 and IL-4.
6643 24027025 HbR-DNA vaccination also induced a protective response by generating multifunctional CD4(+) and CD8(+) T cells.
6644 24034934 Here, we demonstrate activation of signal 2, by anti-CD28 mAb (aCD28) and other costimulatory molecules (aCD49d, aCD5), and signal 3, by recombinant IL-12, enhance Ag-specific IFN-γ secretion by CD4, CD8, γδ T cells and NK cells.
6645 24043884 The roles of IRF-3 and IRF-7 in innate antiviral immunity against dengue virus.
6646 24043884 We investigated the roles of IFN regulatory factor (IRF)-3 and IRF-7 in innate antiviral immunity against dengue virus (DENV).
6647 24043884 IFN-α/β was induced similarly in wild-type and Irf-3(-/-) mice post-DENV infection, whereas in the Irf-7(-/-) and Irf-3(-/-)7(-/-) mice, significantly low levels of IFN-α/β expression was observed within 24 hpi.
6648 24043884 IFN-stimulated gene induction was also delayed in Irf-3(-/-)7(-/-) mice relative to wild-type and single-deficient mice.
6649 24043884 In particular, Cxcl10 and Ifnα2 were rapidly induced independently of both IRF-3 and IRF-7 in the Irf-3(-/-)7(-/-) mice with DENV infection.
6650 24043884 Higher levels of serum IFN-γ, IL-6, CXCL10, IL-8, IL-12 p70, and TNF were also observed in Irf-3(-/-)7(-/-) mice 24 hpi, at which time point viral titers peaked and started to be cleared.
6651 24043884 Ab-mediated blockade experiments revealed that IFN-γ, CXCL10, and CXCR3 function to restrict DENV replication in Irf-3(-/-)7(-/-) mice.
6652 24043884 Additionally, the IFN-stimulated genes Cxcl10, Ifit1, Ifit3, and Mx2 can be induced via an IRF-3- and IRF-7-independent pathway that does not involve IFN-γ signaling for protection against DENV.
6653 24043884 Collectively, these results demonstrate that IRF-3 and IRF-7 are redundant, albeit IRF-7 plays a more important role than IRF-3 in inducing the initial IFN-α/β response; only the combined actions of IRF-3 and IRF-7 are necessary for efficient control of early DENV infection; and the late, IRF-3- and IRF-7-independent pathway contributes to anti-DENV immunity.
6654 24046412 The results showed that both anti-avian influenza virus (AIV) specific secretory IgA level in respiratory tract and anti-AIV specific IgG level in serum significantly increased, as well as the expressions of IL-12, interferon-γ, IL-6, and TLR in the nasal cavity and trachea after intranasal immunization with IAIV and TLR ligand.
6655 24046412 Among the used TLR ligands, B. subtilis spores as the adjuvant for nasal IAIV had the strongest effect on the expression of IL-6 and IL-12 (P < 0.01), whereas the CpG-ODN could present an advantageous effect on the induction of anti-AIV specific IgG and neutralization antibodies (P < 0.01).
6656 24046412 The results showed that both anti-avian influenza virus (AIV) specific secretory IgA level in respiratory tract and anti-AIV specific IgG level in serum significantly increased, as well as the expressions of IL-12, interferon-γ, IL-6, and TLR in the nasal cavity and trachea after intranasal immunization with IAIV and TLR ligand.
6657 24046412 Among the used TLR ligands, B. subtilis spores as the adjuvant for nasal IAIV had the strongest effect on the expression of IL-6 and IL-12 (P < 0.01), whereas the CpG-ODN could present an advantageous effect on the induction of anti-AIV specific IgG and neutralization antibodies (P < 0.01).
6658 24075482 However, the secretion of MCP-1, IL-6, and IL-12 by RAW264.7 cells was affected by GE33.
6659 24093105 Moreover, EDAvidin retains the proinflammatory properties of EDA, inducing NF- κβ by TLR4-expressing cells, as well as the production of TNF- α by the human monocyte cell line THP1 and IL-12 by DC.
6660 24127010 Tumor-infiltrating CD4(+) and CD8(+) T cells were increased after the administration of TSP-1 shRNA.
6661 24127010 The expression of interleukin-12 and interferon-γ in the lymph nodes was enhanced by injection of TSP-1 shRNA.
6662 24127010 Lymphocytes from the mice injected with TSP-1 shRNA selectively killed the tumor cells, and the cytotoxicity of lymphocytes was abolished by depletion of CD8(+) T cells.
6663 24127010 Injection of CD11c(+) TSP-1-knockout (TSP-1-KO) bone marrow-derived DCs (BMDCs) delayed tumor growth in tumor-bearing mice.
6664 24127010 In contrast, the administration of shRNAs targeting TSP-2, another TSP family member, did not extend the survival of tumor-bearing mice.
6665 24130733 The addition of ESAT-6 or HspX alone to BCG-stimulated DC did not improve these processes, whereas their simultaneous addition enhanced BCG-dependent DC maturation and cytokine release, as well as the ability of BCG-treated DCs to stimulate IFN-γ release and CD69 expression by CD4(+) lymphocytes and NK cells.
6666 24130733 Our results indicate that ESAT-6 and HspX cooperation enables BCG-treated human DCs to induce T lymphocyte and NK cell-mediated immune responses through TLR2-dependent IL-12 secretion.
6667 24135589 The in vivo results showed that the mRNA expressions of IL-6, IL-12, interferon-γ, and Toll-like receptor (TLR) 21 in upper respiratory tract tissues increased significantly in the early period after intranasal immunization with inactivated avian H5N1 influenza virus (IAIV) and CpG-ODN (P < 0.01).
6668 24156030 With curcumin before tumor development in the combination therapy, the production of IL-6 was significantly decreased and IL-12 increased by myeloid-derived suppressor cells (MDSC), in correlation with improved CD4 and CD8 T-cell responses in blood.
6669 24158609 The IL-12A rs568408 and IL-12B rs3212227 polymorphisms were analyzed in relation to anti-HBs development in 602 HD patients with negative antibodies to HBV core antigen (anti-HBc) who were hepatitis B vaccinated (group I) as well as in 237 anti-HBc positive HD patients who were infected with HBV in the past (group II).
6670 24158609 In HD patients, the studied IL-12 polymorphic variants seem to be associated with the anti-HBs phenotype (a) with borderline significance for IL-12A in hepatitis B vaccinated patients, and (b) significantly for IL-12B in patients who underwent natural HBV infection.
6671 24158609 The IL-12A rs568408 and IL-12B rs3212227 polymorphisms were analyzed in relation to anti-HBs development in 602 HD patients with negative antibodies to HBV core antigen (anti-HBc) who were hepatitis B vaccinated (group I) as well as in 237 anti-HBc positive HD patients who were infected with HBV in the past (group II).
6672 24158609 In HD patients, the studied IL-12 polymorphic variants seem to be associated with the anti-HBs phenotype (a) with borderline significance for IL-12A in hepatitis B vaccinated patients, and (b) significantly for IL-12B in patients who underwent natural HBV infection.
6673 24176493 Greater proliferation of CD4(+) and CD8(+) T cells was observed in the rBCG-vaccinated groups compared to the control groups.
6674 24176493 The levels of Th1-type IFN-γ, IL-2 and IL-12 were significantly increased following immunisation with the rBCG vaccines via the i.v. or oral route, which indicated that catalytic activity against T. gondii infection was generated in the mice. rBCGpMV361-TgCyP i.v. inoculation resulted in a higher protection efficiency, as demonstrated by the increased survival time and survival rate (17%) of BALB/c mice.
6675 24176819 We have cloned the p35 and p40 cDNAs of IL-12 from orange-spotted grouper (Epinephelus coioides).
6676 24176819 The results indicated that the loss of this 3aa patch during evolution was compensated by the duplication of exon 4 in mammalian p35 to gain another cysteine residue to form a disulfide bond, evidenced by chicken p35 which does not contain NCF corresponding 3-aa patch nor exon 4 duplication.
6677 24176819 We have cloned the p35 and p40 cDNAs of IL-12 from orange-spotted grouper (Epinephelus coioides).
6678 24176819 The results indicated that the loss of this 3aa patch during evolution was compensated by the duplication of exon 4 in mammalian p35 to gain another cysteine residue to form a disulfide bond, evidenced by chicken p35 which does not contain NCF corresponding 3-aa patch nor exon 4 duplication.
6679 24188670 Furthermore, dendritic cells electroporated with survivin and cytokine (i.e., IL-12 and IL-21) mRNA can be used to generate survivin-specific T cells in vitro.
6680 24198430 Infection of DC with either M51R or M51R-F vector induced the production of interleukin-12 (IL-12) and IL-6 and increased surface expression of T cell costimulatory molecules.
6681 24205278 These results suggest that the detection of PPV antigens via Dectin-2 triggers IL-12 production, which induces IFN-γ synthesis by NKT cells and subsequently the production of serotype-specific IgG.
6682 24238342 Lung airway-surveilling CXCR3(hi) memory CD8(+) T cells are critical for protection against influenza A virus.
6683 24238342 Expression of the chemokine receptor CXCR3 was critical for memory CD8(+) T cells to populate the airways during the steady state and vaccination approaches were designed to favor the establishment of memory CD8(+) T cells in the airways.
6684 24238342 Specifically, we found that interleukin-12 (IL-12) signaling shortly after immunization limited CXCR3 expression on memory CD8(+) T cells.
6685 24238342 Neutralization of IL-12 or adjuvants that did not induce high amounts of IL-12 enhanced CXCR3 expression, sustained airway localization of memory CD8(+) T cells, and resulted in superior protection against IAV.

6690 24244265 Inhibition of CD4+CD25+ regulatory T cell function and conversion into Th1-like effectors by a Toll-like receptor-activated dendritic cell vaccine.
6691 24244265 We have previously demonstrated that vaccination with dendritic cells activated with the TLR-4 ligand LPS and IFN-γ promotes an antigen-specific anti-tumor response that prevents tumor recurrence.
6692 24244265 The effect is therefore mediated by a soluble factor but was independent of both IL-6 and IL-12.
6693 24244265 IFN-γ production was associated with upregulation of the Th1 transcriptional regulator T-bet, and a significant fraction of IFN-γ-producing regulators coexpressed T-bet and FoxP3.
6694 24244265 While the effects of the LPS-activated dendritic cell on responder cell proliferation were IL-12 independent, upregulation of T-bet was inhibited by a neutralizing anti-IL-12 antibody.
6695 24252697 In vitro, PS-F2 stimulated dendritic cells (DCs) to produce proinflammatory cytokines, including TNF-α, interleukin (IL)-6, and IL-12/IL-23 p40.
6696 24252697 PS-F2 also stimulated DCs to express the maturation markers CD40, CD80, CD86, and MHC class II.
6697 24252697 In a murine splenocyte culture, PS-F2 treatment resulted in elevated expression of T-bet and interferon (IFN)-γ in T lymphocytes.
6698 24295591 Our previous studies have described dendritic cells (DCs) to be important sources of Th1 cytokines such as IL-12 and IL-2 in vitro, following stimulation with Cryptosporidium parvum antigens.
6699 24295591 Consistent with the in vivo engraftment study, DCs that are pulsed with live sporozoites in vitro and co-cultured with CD4(+) and CD8(+) T cells produced higher IFN-γ levels.
6700 24296809 Most importantly, DCs matured with OK-432 plus IFN-γ-induced maintained secretion of interleukin-12 (IL-12)p70 in secondary culture after stimulus withdrawal.
6701 24296809 Functionally, OK-432 plus IFN-γ-conditioned DCs induce remarkable Th1 and Tc1 responses more effectively than OK-432 alone, even more than the use of α-type-1 cytokine cocktail.
6702 24296812 TNF-α(+) and IFN-γ(+) CD4(+) T cells expressed significantly higher levels of T-box transcription factors T-bet with graded loss of Eomesodermin (Eomes) expression (T-bet(Hi)Eomes(Hi/Lo)) when compared with TNF-α(+) CD4(+) T cells expressing lower levels of both T-bet and Eomes (T-bet(-)Eomes(-)).
6703 24296812 Furthermore, TNF-α(+) and IFN-γ(+) CD4(+) T cells expressed significantly higher levels of perforin and interleukin (IL)-2 and displayed a terminally differentiated phenotype (CCR7(-)CD27(-)CD45RA(-)CD57(+)CD62L(-)).
6704 24296812 In contrast, TNF-α(+) alone CMV-specific CD4(+) T cells were predominantly early-memory phenotype with a proportion of these cells displaying T memory stem-cell phenotype (CD95(+)CD45RA(+)CCR7(+)CD27(+)).
6705 24296812 In vitro stimulation of CMV-specific CD4(+) T cells with viral antigen in the presence of IL-12 was sufficient to dramatically change the transcriptional and functional profile of TNF-α(+) CD4(+) T cells, whereas TNF-α(+) and IFN-γ(+) CD4(+) T cells remained unaltered.
6706 24308155 Celecoxib may reduce production of prostaglandin E2 and modulate the balance between T helper 1 (Th1) cytokines and T helper 2 (Th2) cytokines by increasing the pivotal Thl cytokine interleukin-12 and reducing Th2 cytokine interleukin-10.
6707 24319444 NKp46/NCR1(+) CD3(-) cells constituted 2-11% of mononuclear cells in afferent lymph (AL), a majority of cells were CD16(+), CD8α(+), and CD2(-/low), and elevated CD25 and CD44 expression indicated an activated phenotype.
6708 24319444 A large proportion of lymph and blood NK cells produced interferon (IFN)-γ following stimulation with IL-2 and IL-12.
6709 24336457 Furthermore, an in vitro mechanistic study showed that wolfberry supplementation enhanced maturation and activity of antigen-presenting dendritic cells (DCs) in aged mice, as indicated by phenotypic change in expression of DC activation markers major histocompatibility complex class II, cluster of differentiation (CD) 40, CD80, and CD86, and functional change in DC production of cytokines interleukin-12 and tumor necrosis factor-α as well as DC endocytosis.
6710 24336457 Also, adoptive transfer of wolfberry-treated bone marrow DCs (loaded with ovalbumin(323-339)-peptide) promoted antigen-specific T cell proliferation as well as interleukin-4 and interferon-γ production in CD4(+) T cells.
6711 24370734 Moreover, rLdTPR reasonably stimulated PBMCs of cured Leishmania patients to produce IFNγ, IL-12, and TNF-α but not IL-4 or IL-10.
6712 24370734 On the other hand, the protein downregulated LPS-induced IL-10 as well as soluble L. donovani antigen-induced IL-4 production in PBMCs of Leishmania patients.
6713 24370734 The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFNγ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.
6714 24385384 It was observed that PA-MSHA activated PMSM towards a classical activation phenotype via a toll-like receptor4/9-dependent mechanism, which increased interleukin-12 levels and promoted the expression of co-stimulatory and antigen-presenting molecules like CD80, CD86, and MHC-II (P < 0.05).
6715 24394635 The knockdown of SOCS1 in BMDCs by PLGA (OVA/SOCS1 siRNA) NPs enhanced pro-inflammatory cytokine (tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-12 and IL-2) expression.
6716 24394635 Additionally, PLGA (OVA/SOCS1 siRNA) NP-treated BMDCs could elicit an immune response through cross-presentation in OVA-specific CD8 T cells that express IL-2 cytokine.
6717 24396491 The present study evaluated the protective effects of intranasally administered live L. lactis strains carrying human papillomavirus 16 E7 protein and murine interleukin-12 (IL-12) DNA (LL-E7P-IL-12D) in a TC-1 tumor animal model.
6718 24396491 IL-12 and interferon-γ serum levels were measured and immunization with LL-E7P-IL-12D was shown to induce an E7-specific immune response and to confer protection against TC-1-induced tumors in vivo.
6719 24396491 The present study evaluated the protective effects of intranasally administered live L. lactis strains carrying human papillomavirus 16 E7 protein and murine interleukin-12 (IL-12) DNA (LL-E7P-IL-12D) in a TC-1 tumor animal model.
6720 24396491 IL-12 and interferon-γ serum levels were measured and immunization with LL-E7P-IL-12D was shown to induce an E7-specific immune response and to confer protection against TC-1-induced tumors in vivo.
6721 24404428 New data suggest that the clinical efficacy of DC-based vaccines may be dependent on the paracrine production of interleukin-12 in the course of antigen presentation and the consequent development of therapeutic Type 1 CD8+ T-cell immunity.
6722 24445619 There was significant upregulation of maturation markers (CD80, CD86, MHC-I, and MHC-II) in argon-helium freeze-thawed lysate-pulsed DCs.
6723 24445619 The concentration of interleukin-6 (IL-6), IL-1β, tumor necrosis factor-α, and IL-12 secreted by lysate-pulsed DCs was increased.
6724 24467650 Stimulation of THP-1 macrophages with recombinant PE35 and PPE68, singly or in combination, led to a dose-dependent increase in levels of the anti-inflammatory cytokine interleukin (IL)-10 and the chemokine monocyte chemoattractant protein-1, and caused a reciprocal decrease in levels of the proinflammatory cytokine IL-12.
6725 24467650 PE35/PPE68-stimulated production of IL-10 and monocyte chemoattractant protein-1 was observed to be dependent on toll-like receptor 2, as receptor blockade caused a significant reduction in their levels.
6726 24480625 Three-dimensional, porous polymer matrices loaded with tumor lysates and presenting distinct combinations of granulocyte macrophage colony-stimulating factor (GM-CSF) and various Toll-like receptor (TLR) agonists affected 70% to 90% prophylactic tumor protection in B16-F10 melanoma models.
6727 24480625 Regression analysis revealed that the numbers of vaccine-resident CD8(+) DCs, plasmacytoid DCs (pDC), along with local interleukin (IL)-12, and granulocyte colony-stimulating factor (G-CSF) concentrations correlated strongly to vaccine efficacy regardless of adjuvant type.
6728 24480625 Furthermore, vaccine studies in Batf3(-/-) mice revealed that CD8(+) DCs are required to affect tumor protection, as vaccines in these mice were deficient in cytotoxic T lymphocytes priming and IL-12 induction in comparison with wild-type.
6729 24480625 Specifically, these results suggest that CD8(+) DCs, pDCs, IL-12, and G-CSF play important roles in priming effective antitumor responses with these vaccines.

6734 24556719 Host interleukin (IL)-23 suppresses the immune response during tumor initiation, growth, and metastases, and neutralization of IL-23 causes IL-12-dependent antitumor effects.
6735 24556719 Here, we report that combining agonistic anti-CD40 monoclonal antibodies (mAb) to drive IL-12 production and anti-IL-23 mAbs to counter the tumor promoting effects of IL-23 has greater antitumor activity than either agent alone.
6736 24556719 Overall, these data suggest the clinical potential of using anti-CD40 (push) and anti-IL-23 mAbs (pull) to tip the IL-12/23 balance in established tumors.

6743 24561129 This pcDNA-VP2 vaccine clearly induced an innate and specific immune-response, significantly up-regulating IFN-1, IFN-γ, Mx-1, IL8, IL12, IgM and IgT expression.
6744 24579457 A novel recombinant BCG (BCG-DHTM), that was deficient in urease, expressed with gene encoding the fusion of BCG-derived HSP70 and M. tuberculosis-derived major membrane protein (MMP)-II, was constructed for use as a vaccine against tuberculosis.
6745 24579457 BCG-DHTM efficiently activated dendritic cells (DC) to induce cytokine production, including IL-12, TNFalpha and IL-1beta and phenotypic changes.
6746 24579457 The DC infected BCG-DHTM was more potent in activation of native T cells of CD4 and CD8 subsets than those infected vector control BCG.
6747 24579457 Further, BCG-DHTM seemed to activate native CD4+ T cells and native CD8+ T cells by antigen-specific fashion.
6748 24579457 The primary infection of BCG-DHTM in C57BL/6 mice for 12 weeks efficiently produced T cells responsive to in vitro secondary stimulation with MMP-II, HSP70 and H37Rv-derived cytosolic protein and inhibited with multiplication of subsequently challenged M. tuberculosis in lungs at least partially.
6749 24579458 We found that this peptide induced the expression of T-bet and TATA box binding protein-associated factor that can induce the chromatin remodeling of ifn-gamma gene, and as a result induced Th1 differentiation even in the absence of IFN-gamma and IL-12.
6750 24579458 Next, we established an in vitro CTL differentiation system using Peptide-25, Peptide-25 specific CD4+ T cells, OVA specific CD8+ T cells and splenic DC.
6751 24579458 By using this system, we found that CD4+ T cells activated DC even in the absence of IFN-gamma and CD40 ligand association, and the activated DC induced the functional differentiation of CTL.
6752 24589970 No significant difference was observed in cytokine levels of IL-1β, IL-4, IL-6, IL-10, IL-12, IFN-γ, MIP-1, TNF-α, and prostaglandin E2 (PGE2) in sera between the two groups.
6753 24600592 Anti-Listeria protection was related to the changes in DC maturation caused by these epitopes, with high production of interleukin-12 as well as significant levels of other Th1 cytokines such as monocyte chemotactic protein-1, tumor necrosis factor-α, and interferon-γ, and with the induction of GAPDH1-22-specific CD4(+) and CD8(+) immune responses.
6754 24600592 This is believed to be the first study to explore the use of a novel GAPDH antigen as a potential DC-based vaccine candidate for listeriosis, whose efficiency appears to highlight the relevance of vaccine designs containing multiple CD4(+) and CD8(+) epitopes.
6755 24618498 IL-12 and IL-27 regulate the phagolysosomal pathway in mycobacteria-infected human macrophages.
6756 24619679 The effective induction of TAA-specific T cell immune responses requires activation of T cells by CD3/CD28 antibodies and the presence of proinflammatory cytokines such as interleukin-7 (IL-7) and interleukin-12 (IL-12).
6757 24631074 Combination therapy also resulted in increased circulating levels of IL10 four weeks post-vaccination and IL2 for 12 weeks post-vaccination, but without effect on proinflammatory cytokines IL6, IL12(p70), IL17 and IFNγ.
6758 24659689 Compared to wild-type, a hip1 mutant strain of M. tuberculosis induced enhanced levels of the key Th1-inducing cytokine IL-12, as well as other proinflammatory cytokines (IL-23, IL-6, TNF-α, IL-1β, and IL-18) in DCs via MyD88- and TLR2/9-dependent pathways, indicating that Hip1 restricts optimal DC inflammatory responses.
6759 24659689 Infection with the hip1 mutant also induced higher levels of MHC class II and costimulatory molecules CD40 and CD86, indicating that M. tuberculosis impairs DC maturation through Hip1.
6760 24680943 Different time points after boosting, we measured serum antibodies in blood samples and separated splenocytes to detect lymphocyte proliferation and the production of IL-4, IL-10, IL-12, and IFN-γ in vitro.
6761 24680943 We also compared immunizations containing 20μl RV and 20μl RV adjuvanted with Re (5.00mg/kg) for the expression of CD4(+) and CD8(+) T-cell subsets at different time points.
6762 24680943 Results indicated that co-administration of Re significantly enhanced serum antibody titers, increased the CD4(+):CD8(+) ratio, and enhanced both proliferation responses and IL-4, IL-10, IL-12 and IFN-γ secretions.
6763 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.
6764 24789795 However, IL-4 and IL-10 were not produced in the vaccinated mice.

6766 24866378 Protease-activated receptor 1 suppresses Helicobacter pylori gastritis via the inhibition of macrophage cytokine secretion and interferon regulatory factor 5.
6767 24866378 Although protease-activated receptor 1 (PAR1) has been identified as one such host factor, its mechanism of action is unknown.
6768 24866378 Using chimeric mice, we demonstrated that PAR1-mediated protection against H. pylori gastritis requires bone marrow-derived cells.
6769 24866378 Analyses of the gastric mucosa revealed that PAR1 suppresses cellular infiltration and both T helper type 1 (Th1) and T helper type 17 (Th17) responses to infection.
6770 24866378 Moreover, PAR1 expression was associated with reduced vaccine-mediated protection against H. pylori.
6771 24866378 Analyses of H. pylori-stimulated macrophages revealed that PAR1 activation suppressed secretion of interleukin (IL)-12 and IL-23, key drivers of Th1 and Th17 immunity, respectively.
6772 24866378 Furthermore, PAR1 suppressed interferon regulatory factor 5 (IRF5), an important transcription factor for IL-12 and IL-23, both in the infected mucosa and following bacterial stimulation.
6773 24866378 PAR1 suppression of IRF5 and IL-12/23 secretion by macrophages provides a novel mechanism by which the host suppresses the mucosal Th1 and Th17 response to H. pylori infection.

6792 24898325 After an antigen stimulus with B. ovis cells, splenocytes obtained from all vaccinated mice secreted similar levels of TNF-α and IL12(p40) and remarkably high amounts of IFN-γ, a crucial cytokine in protective immunity against other Brucella species.
6793 24898325 By contrast, IL-1α -an enhancer of T cell responses to antigen- was present at higher levels in mice vaccinated with the B. ovis mutants, while IL-10, an anti-inflammatory cytokine, was significantly more abundant in Rev 1-vaccinated mice.
6794 24898389 Rapamycin enhanced IL-12 signaling by upregulating IL-12 receptor β2 expression and signal transducer and activator of transcription factor 4 phosphorylation in CTLs during early infection.

6798 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.
6799 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.
6800 24945624 Spleens from mice infected with BCG-TB1860 also harboured significantly fewer DC expressing MHC-II, IL-12, IL-2 and TNF-α compared to mice infected with BCG-GFP.
6801 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.
6802 24995396 In lymphocyte transformation assay, splenocytes of immunized mice exhibited a strong recall proliferative response with high amounts of IFN-γ, IL-12, IL-10 and IL-6 and very low levels of IL-5 and IL-4 production.

6806 25019567 Blocking assays showed that TLR2-, but not TLR4-neutralizing antibody reduced expression of TNF-α, IL-6 and IL-12 p40 in RAW264.7 cells. rTB10.4 stimulation activated p38 kinase (p38) and extracellular-regulated kinase (ERK) was TLR2-dependent, whereas inhibition of p38 and ERK activity significantly reduced TNF-α, IL-6 and IL-12 p40 production.
6807 25019567 Furthermore, rTB10.4 stimulation of RAW264.7 cells resulted in TLR2-mediated activation of NF-κB and induced translocation of NF-κB p65 from the cytoplasm to the nucleus via IκBα degradation. rTB10.4-induced TNF-α, IL-6 and IL-12 p40 release was attenuated by the specific IκB phosphorylation inhibitor, BAY 11-7082.

6821 25019567 Recombinant TB10.4 of Mycobacterium bovis induces cytokine production in RAW264.7 macrophages through activation of the MAPK and NF-κB pathways via TLR2.
6822 25019567 The TB10.4 antigen of Mycobacterium bovis/Mycobacterium tuberculosis induces a strong Th1 CD4+ T-cell response.
6823 25019567 Here, as stimulated RAW264.7 cells with recombinant TB10.4 (rTB10.4), derived from M. bovis, increased TNF-α, IL-6 and IL-12 p40 secretin in a dose-dependent manner.
6824 25019567 Blocking assays showed that TLR2-, but not TLR4-neutralizing antibody reduced expression of TNF-α, IL-6 and IL-12 p40 in RAW264.7 cells. rTB10.4 stimulation activated p38 kinase (p38) and extracellular-regulated kinase (ERK) was TLR2-dependent, whereas inhibition of p38 and ERK activity significantly reduced TNF-α, IL-6 and IL-12 p40 production.
6825 25019567 Furthermore, rTB10.4 stimulation of RAW264.7 cells resulted in TLR2-mediated activation of NF-κB and induced translocation of NF-κB p65 from the cytoplasm to the nucleus via IκBα degradation. rTB10.4-induced TNF-α, IL-6 and IL-12 p40 release was attenuated by the specific IκB phosphorylation inhibitor, BAY 11-7082.
6826 25019567 These findings indicate that the M. bovis-derived rTB10.4 induced production of TNF-α, IL-6 and IL-12 p40 involves p38, ERK and NF-κB via the TLR2 pathway.

6828 25108787 Increased expression of IGHG1, IL6, IL1α, and IL1RN in bovine tick bite-site biopsies suggests that Th2 differentiation may be important for the local bovine response to A. americanum ticks.
6829 25108787 The up-regulation of IL12 and IL23 in blood leukocytes from Lone Star tick-infested calves of all phenotypes suggests a possible systemic recruitment of memory T cells.
6830 25123642 Western blot analysis, using monoclonal antibodies, demonstrated that the crucial inter-subunit disulfide bond linking the p35 and p40 subunits is intact in the purified hIL-12.
6831 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.
6832 25135492 Using DNASTAR 6.0 software, potential antigenic epitopes were predicted, and six regions were chosen to generate recombinant plasmids with the pMV361 vector (pMV361-E2-1, pMV361-E2-2, pMV361-E2-3, pMV361-E2-4, pMV361-E2-5 and pMV361-E2-6, respectively).
6833 25135492 Ratios and numbers of CD4+, CD8+ and IL-12 expressing spleen lymphocytes of the rBCG-E2-6 group also were higher than those of other groups.
6834 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.
6835 25208333 Survival of mice was associated with bacterial clearance, an increased number of splenic leukocytes, and high levels of interleukin-12, interferon γ and tumor necrosis factor α in spleens as well as in sera.
6836 25215861 Flow cytometry showed that surface EnvG bound various conformationally- and trimer-specific antibodies (Abs), and in-vitro growth assays on CD4+CCR5+ cells demonstrated EnvG functionality.
6837 25215861 Significant quantities of Env-specific CD4+ T cells were also detected, which were augmented as much as 70-fold by priming with IM electroporated plasmids encoding EnvG and IL-12.
6838 25225247 The results also demonstrated the ability of Fh12 to downregulate the secretion of the proinflammatory and inflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-12 (IL-12), and IL-1βB, even after stimulation with lipopolysaccharide (LPS), as well as its ability to stimulate the overexpression of IL-10.
6839 25240754 Although comparable levels of antigen-specific IgG2a and IgG1 were observed in immunized mice, high amounts of IFN-γ, IL-12 and IL-6, no detectable level of IL-4 and very low levels of IL-10 and IL-5 were produced by splenocytes of vaccinated mice suggesting induction of a Th1 dominant immune response by DnaK.
6840 25250027 TLR2 Signaling is Required for the Innate, but Not Adaptive Response to LVS clpB.
6841 25250027 We sought to determine whether TLR2 signaling was required during the immune response to LVS clpB.
6842 25250027 TLR2 knock-out (TLR2 KO) mice previously infected with LVS clpB are completely protected during a lethal challenge with LVS.
6843 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.
6844 25250027 TLR2 signaling was important, however, for the innate immune response to LVS clpB.
6845 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.
6846 25250027 IL-6, IL-12, IP-10, KC, and MIG production were partially dependent on TLR2 signaling.
6847 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.
6848 25296161 IL-23 p19 knockout mice exhibit minimal defects in responses to primary and secondary infection with Francisella tularensis LVS.
6849 25296161 Thus p40 has a novel role in clearance of LVS infection that is unrelated to either IL-12 or IL-23.
6850 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.
6851 25312957 In addition, the frequency and number of gamma interferon (IFN-γ)-secreting effector memory (EM) CD4(+) T cells elicited by F. tularensis infection (postimmunization) is increased in an interleukin 12 (IL-12)-dependent manner.

6884 25346485 Interleukin-27 (IL-27) is a unique cytokine that has both inflammatory and immune suppressive activities.
6885 25346485 However, the specific effect of IL-27 during DC differentiation and how that may change the nature of the antigen-presenting cell has not been investigated.
6886 25346485 In this report, we show that IL-27 treatment during monocyte-derived DC differentiation enhanced the ability to process antigens and stimulate T-cell activity.
6887 25346485 DCs differentiated in the presence of IL-27 showed enhanced acidification of latex bead-containing phagosomes that was consistent with elevated expression of vacuolar-ATPases.
6888 25346485 In addition, the levels of MHC class II surface expression were higher in DCs differentiated in the presence of IL-27.
6889 25346485 Production of IL-12 was also significantly increased during S. aureus infection of IL-27-differentiated DCs.
6890 25360749 DC treatment with EV71 VLPs enhanced the expression of CD80, CD86, CD83, CD40, CD54, and HLA-DR on the cell surface; increased the production of interleukin (IL)-12 p40, IL-12 p70, and IL-10 by DCs; and suppressed the capacity of DCs for endocytosis.
6891 25360749 Neutralization with antibodies against Toll-like receptor (TLR) 4 suppressed the capacity of EV71 VLPs to induce the production of IL-12 p40, IL-12 p70, and IL-10 by DCs and inhibited EV71 VLPs binding to DCs.
6892 25360749 DC treatment with EV71 VLPs enhanced the expression of CD80, CD86, CD83, CD40, CD54, and HLA-DR on the cell surface; increased the production of interleukin (IL)-12 p40, IL-12 p70, and IL-10 by DCs; and suppressed the capacity of DCs for endocytosis.
6893 25360749 Neutralization with antibodies against Toll-like receptor (TLR) 4 suppressed the capacity of EV71 VLPs to induce the production of IL-12 p40, IL-12 p70, and IL-10 by DCs and inhibited EV71 VLPs binding to DCs.
6894 25429207 In particular, dendritic cells secrete less IL-12 and IL-18, CD8pos T cells and NK cells have defective cytolysis and cytokine production, and CD4pos T cell responses tend to bias towards a Th2 phenotype and promotion of regulatory T cells (Tregs).
6895 25454807 Mice bearing colon carcinoma MC38 were given single dose of cyclophosphamide (CY) followed by alternate injections of anti-IL-10 antibodies and BMDC-based vaccines consisted of BMDCs stimulated with MC38 tumour antigen (BMDC/TAg) or the combination of BMDC/TAg with BMDCs transduced with IL-12 genes (BMDC/IL-12).
6896 25454807 The high tumour growth inhibition was observed in mice treated with CY+anti-IL-10+BMDC/TAg as well as CY±anti-IL-10+BMDC/TAg+BMDC/IL-12.
6897 25454807 Whereas, application of anti-IL-10 Abs just before injection of BMDC/TAg+BMDC/IL-12 did not enhanced NK cell activity.
6898 25454807 Mice bearing colon carcinoma MC38 were given single dose of cyclophosphamide (CY) followed by alternate injections of anti-IL-10 antibodies and BMDC-based vaccines consisted of BMDCs stimulated with MC38 tumour antigen (BMDC/TAg) or the combination of BMDC/TAg with BMDCs transduced with IL-12 genes (BMDC/IL-12).

6903 25454807 Whereas, application of anti-IL-10 Abs just before injection of BMDC/TAg+BMDC/IL-12 did not enhanced NK cell activity.
6904 25454862 Further analysis proved that co-stimulatory molecules (CD40, CD80, CD86 and MHC-II), regulatory protein (IRF-7 and TRAF-6) and pro-inflammatory cytokines (IL-1, IL-6 and IL-12) were all changed and involved in DCs maturation.
6905 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.
6906 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.
6907 25467796 Murine bone marrow-derived dendritic cells stimulated with OprI-OVA fusion lipoprotein produced high levels of the pro-inflammatory cytokines TNF-α and IL-6 and also IL-10, IL-12(p70) and IL-27, while TGF-β and IL-23 were not detected.
6908 25553824 Intranasal immunization of mice with the Cryj1/sDNA hydrogel resulted in high levels of Cryj1-specific IgG in nasal lavage fluid (NFL), IL-12 and interferon-γ release from spleen cells after re-stimulation with Cryj1 when compared with intranasal immunization with the other formulations examined.
6909 25619587 The vaccine containing Metastim(®) elicited significantly higher gene expression of interferon-γ, IL-12, CD4 and CD83 compared to alum (p<0.05).
6910 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.
6911 25627812 Importantly, although interleukin (IL)-23 is critical, IL-12 and IL-21 are dispensable for protective Th17 recall responses.
6912 25692288 The latter was apparent from up-regulation of co-stimulatory molecules and from secretion of a wide range of inflammatory cytokines and chemokines including the Th1-governing cytokine IL-12, in keeping with the IgG2a antibody isotype distribution.
6913 25700780 This study evaluated the role of the mitogen-activated protein kinase (MAPK)-p38 pathway in the nitric oxide synthase (iNOS) expression and nitric oxide (NO) production by bovine monocyte-derived macrophages ingesting Mycobacterium avium subsp. paratuberculosis (MAP) organisms in vitro.
6914 25700780 Bovine monocyte-derived macrophages were incubated with MAP organisms with or without a specific inhibitor of the MAPKp38 pathway and activation of the MAPKp38, interleukin - (IL) IL-10, IL-12, iNOS mRNA expression and NO production were evaluated.

6944 25748337 Upon PFWE treatment, BM-DCs dose-dependently upregulated the expression of CD40, CD80, CD86 and MHC II and increased the production of IL-12, IL-6 and tumor necrosis factor (TNF)-α but not for IL-10, which is mediated by TLR4 signaling pathway, at least partially.
6945 25761460 The levels of interleukin-1α (IL-1α), IL-1β, IL-6, IL-12(p70), and IL-8 were elevated, whereas the IL-1RA/IL-1(α+β) ratio decreased in women with BV.
6946 25763999 Here, we used enzyme-linked immunosorbent assays with anti-CII IgG antibodies, quantified the expression levels of Th1, Th2, and Th3 cytokines, and performed flow cytometric analyses of different T-cell subsets, including Th1, Th2, Th17, Tc, Ts, Treg, and CD4(+)CD29(+)T cells to systemically evaluate humoral and cellular immune responses to pcDNA-CCOL2A1 vaccine in normal rats.

6948 25763999 However, transforming growth factor (TGF)-β levels were significantly increased on days 10 and 14, while interferon (IFN)-γ and tumor necrosis factor (TNF)-α levels were significantly decreased on days 28 and 35 after vaccination(P < 0.05).
6949 25763999 Similarly, there were no significant differences in the percentages of Tc, Ts, Th1/Th2, and Th17 cells between the 2 groups(P > 0.05), with the exception of Treg cells, which were significantly reduced on days 14 and 21 after vaccination (P < 0.05), and CD4(+)CD29(+)T cells, which were significantly increased on days 7 and 14 after vaccination(P < 0.05).Taken together, these results suggested that pcDNA-CCOL2A1 vaccine did not markedly affect the balance of immune system components in vaccinated normal rats, indicating that this DNA vaccine may have clinical applications in the treatment of RA.
6950 25765676 Under identical conditions, CD1c DC synthesized no IL-10 and no or low levels of IL-12.
6951 25765676 This finding was supported by studies on a patient with a highly reduced ability to synthesize IL-12, whose CD1c DC induced a good Th1 response contrasting with the failure of his moDC, which were impaired in IL-12 production, to induce IFN-γ-secreting T cells.
6952 25765676 The IL-10 and IL-12 data were confirmed by microarray analysis, which also showed that stimulated moDC produced inflammatory-associated chemokines and cytokines, whereas stimulated CD1c DC showed minimal up-regulation of these genes.

6972 25856903 The surface antigens of T. gondii with the potential for application as antigens of diagnosis and vaccines have been studied extensively in recent years, especially for P43, P35, P30, P23 and P22.
6973 25892368 The vaccine mimicked the action of the virus, although stronger expression of immune-related genes, except for IFN-1 and IL12, was detected in survivors from the virus control (carrier) group than in those from the vaccinated group.
6974 25930741 Interleukin-10, IL-12 and IL-27 were produced in vitro by Conj-stimulated bone marrow dendritic cells, whereas IL-10 and IFN-γ were up-regulated in co-cultures of CD11c(+) and CD4(+) T cells from Conj-treated mice stimulated with allergen.

6979 25944279 Consistently, at the peak of the disease greater number of reactivated CD4+CD134+CD45RC- T lymphocytes was retrieved from male rat spinal cord.
6980 25944279 Additionally, oppositely to the expression of mRNAs for IL-12/p35, IL-10 and IL-27/p28, the expression of mRNA for IL-23/p19 was upregulated in male rat spinal cord mononuclear cells.
6981 25944279 Within this subpopulation, the IL-17+IFN-γ+:IL-17+IL-10+ cell ratio was shifted towards IL-17+IFN-γ+ cells, which have prominent tissue damaging capacity.
6982 25944279 This was associated with an upregulated expression of mRNAs for IL-1β and IL-6, but downregulated TGF-β mRNA expression in male rat spinal cord mononuclear cells.
6983 25944279 The enhanced GM-CSF mRNA expression in these cells supported the greater pathogenicity of IL-17+ T lymphocytes infiltrating male spinal cord.
6984 25944279 In the inductive phase of the disease, contrary to the draining lymph node, in the spinal cord the frequency of CD134+ cells among CD4+ T lymphocytes and the frequency of IL-17+ cells among T lymphocytes were greater in male than in female rats.

6986 25949867 Dab2-silencing was accompanied by enhanced IL-12 and IL-6 expression, and an improved capacity of DC for antigen uptake, migration and T cell stimulation, which generated strong CTL in vaccinated mice.
6987 25951312 Our data showed that D/P vaccine elicited CD4+ (30-38%) and CD8+ (22-42%) T cells maintained an effector phenotype up to 180 dpv, and were capable of responding to antigenic stimulus or challenge infection by a rapid expansion (CD8>CD4) with type 1 cytokine (IFNγ+ and TFNα+) production and cytolytic T lymphocyte (CTL) activity.
6988 25951312 Co-delivery of IL-12- and GMCSF-encoding expression plasmids provided no significant benefits in enhancing the anti-parasite efficacy of the vaccine-induced T cell immunity.
6989 25951312 Booster immunization (bi) with recombinant TcG2/TcG4 proteins 3-months after primary vaccine enhanced the protective efficacy, evidenced by an enhanced expansion (1.2-2.8-fold increase) of parasite-specific, type 1 CD4+ and CD8+ T cells and a potent CTL response capable of providing significantly improved (3-4.5-fold) control of infecting T. cruzi.
6990 25954597 Thus, we engineered a collection of lentivectors that simultaneously co-expressed an antigen, a PD-L1-silencing shRNA, and various T cell-polarising cytokines, including interferon γ (IFNγ), transforming growth factor β (TGFβ) or interleukins (IL12, IL15, IL23, IL17A, IL6, IL10, IL4).
6991 25954597 In a syngeneic B16F0 melanoma model and using tyrosinase related protein 1 (TRP1) as a vaccine antigen, we found that simultaneous delivery of IL12 and a PD-L1-silencing shRNA was the only combination that exhibited therapeutically relevant anti-melanoma activities.

7034 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.
7035 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.

7056 26182986 We isolated RNA from peripheral blood mononuclear cells and, with PCR, detected transcripts for TLRs 2, 3, 4, 5, 6, 7, 8, 9, 10 and 13.
7057 26182986 Stimulation of the mononuclear cells with agonists to these TLRs increased the expression of downstream TLR signaling products (IL1α, IL6, IL12A and IFNβ).
7058 26188153 In this study, we explored the underlying mechanisms concerning the interaction between Coa-ASC16 and the immune system and we found that the whole inflammatory response elicited by Coa-ASC16 (leukocyte recruitment and IL-1β, IL-6 and IL-12 production) was dependent on the MyD88 protein.
7059 26188153 TLR2, TLR4, TLR7 and NLRP3-inflammasome signaling were not required for induction of this inflammatory response.

7069 26262583 In this study, mice vaccinated with Meso-VAX and adeno-associated virus (AAV)-IL-12 exhibited dramatic increases in the number of mesothelin-specific CD4(+) helper and CD8(+) cytotoxic T-cell precursors, higher titers of anti-mesothelin Abs and in vitro tumor killing activity, and all of these mice were tumor-free after 60 days of tumor challenge.
7070 26262583 CD4(+) helper and CD8(+) cytotoxic T lymphocytes were essential for the antitumor effect generated by Meso-VAX combined with AAV-IL-12.
7071 26283480 YFV induced an increased functional responsiveness to IL-12 and IL-18, as well as to K562 cells, indicating that the NK cells were primed in vivo.
7072 26283480 The NK cell responses were associated primarily with the stage of differentiation, because the magnitude of induced Ki67 and CD69 expression was distinctly higher in CD57(-) NK cells.
7073 26283480 Taken together, our results indicate that NK cells are primed by type I/III IFN in vivo early after YFV infection and that their response is governed primarily by the differentiation stage, independently of killer cell Ig-like receptor/HLA class I-mediated inhibition or education.
7074 26308597 In this study, we investigated the efficacy of a combination therapy consisting of PD-L1 immune checkpoint blockade and whole cell vaccination in a HER-2 positive mouse model of breast cancer.
7075 26308597 We demonstrate that tumorigenicity is completely abrogated when adjuvanted with immune stimulatory molecules (ISMs) B7-1 and a cell-surface anchored (GPI) form of IL-12 or GM-CSF.
7076 26308597 This protection was significantly hindered following CD4 or CD8 depletion indicating the essential role played by cellular immunity.
7077 26324348 Using a mouse model of cytomegalovirus infection, we demonstrate that individual pro-inflammatory IL-12, IL-18, and type I-IFN signaling pathways are indispensible and play non-redundant roles in the generation of virus-specific NK cell memory.
7078 26367128 Spleen cells from mice inoculated with the individual proteins or with the polyproteins vaccine plus saponin showed a protein-specific production of IFN-γ, IL-12, and GM-CSF after an in vitro stimulation, which was maintained after infection.
7079 26377033 We show that codelivery of IL-12 by VSV-G-LVs or DC2.1-LVs augments CD4(+) or CD8(+) T-cell proliferation, respectively.
7080 26377033 Furthermore, we demonstrate that codelivery of IL-12 enhances the CD4(+) TH 1 profile irrespective of its delivery mode, while an increase in cytotoxic and therapeutic CD8(+) T cells was only induced upon VSV-G-LV injection.
7081 26377033 While codelivery of IL-12 by DC2.1-LVs did not enhance CD8(+) T-cell performance, it increased expression of inhibitory checkpoint markers Lag3, Tim3, and PD-1.
7082 26377033 Finally, the discrepancy between CD4(+) T-cell stimulation with and without functional CD8(+) T-cell stimulation by VSV-G- and DC2.1-LVs is partly explained by the observation that IL-12 relieves CD8(+) T cells from CD4(+) T-cell help, implying that a T(H)1 profile is of minor importance for antitumor immunotherapy if IL-12 is exogenously delivered.
7083 26391398 Ac2PIM-responsive miR-150 and miR-143 target receptor-interacting protein kinase 2 and transforming growth factor beta-activated kinase 1 to suppress NOD2-induced immunomodulators.
7084 26391398 While Ac2PIM treatment of macrophages compromised their ability to induce NOD2-dependent immunomodulators like cyclooxygenase (COX)-2, suppressor of cytokine signaling (SOCS)-3, and matrix metalloproteinase (MMP)-9, no change in the NOD2-responsive NO, TNF-α, VEGF-A, and IL-12 levels was observed.
7085 26391398 Further, genome-wide microRNA expression profiling identified Ac2PIM-responsive miR-150 and miR-143 to target NOD2 signaling adaptors, RIP2 and TAK1, respectively.
7086 26391398 Interestingly, Ac2PIM was found to activate the SRC-FAK-PYK2-CREB cascade via TLR2 to recruit CBP/P300 at the promoters of miR-150 and miR-143 and epigenetically induce their expression.
7087 26391398 Loss-of-function studies utilizing specific miRNA inhibitors establish that Ac2PIM, via the miRNAs, abrogate NOD2-induced PI3K-PKCδ-MAPK pathway to suppress β-catenin-mediated expression of COX-2, SOCS-3, and MMP-9.
7088 26397973 Thirty days after immunization, the percentages of effector memory T (TEM) cells (CD4+ and CD8+/CD44high/CD62Llow) and memory CD8+ T cells (CD8+/CD44high/CD62Llow/CD127+) were measured with flow cytometry.
7089 26397973 Interferon γ, interleukin 12 (IL-12), and IL-10 mRNAs were also quantified in whole spleen cells and purified B cells (CD43-) with real-time qPCR.
7090 26397973 Our data suggest that a B-cell subpopulation expressing IL-10 downregulated proinflammatory cytokine expression in the spleen, increasing the survival of CD4+ TEM cells and CD8+ TEM/CD127+ cells.
7091 26405596 Indeed, compared with NK cells with intact TLR3, Tlr3-/- NK cells produced significantly reduced pro-inflammatory cytokines, including IFNγ, when incubated in the presence of different combinations of IL-12, IL-18 and IL-15.
7092 26439698 PPE26 functionally stimulates macrophage activation by augmenting pro-inflammatory cytokine production (TNF-α, IL-6 and IL-12 p40) and the expression of cell surface markers (CD80, CD86, MHC class I and II).
7093 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.
7094 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.
7095 26457798 Protected mice showed anti-Leishmania IgG2a antibodies and a predominant IL-12-driven IFN-γ production (mainly produced by CD4(+) T cells) against parasite proteins, whereas unprotected controls showed anti-Leishmania IgG1 antibodies and parasite-mediated IL-4 and IL-10 responses.
7096 26457798 Vaccinated mice showed an anti-LiHyD IgG2a humoral response, and their spleen cells were able to secrete LiHyD-specific IFN-γ, IL-12 and GM-CSF cytokines before and after infection.
