153 18549798 Differentiation of naive CD4+ T cells into T helper type 1 (Th1) effector cells requires both T cell receptor (TCR) signaling and cytokines such as interleukin-12 and interferon gamma (IFN-gamma).
154 18549798 Here, we report that a third cytokine signal, mediated by the Janus family tyrosine kinase 3 (Jak3) and signal transducer and activator of transcription 5 (STAT5) pathway, is also required for Th1 cell differentiation.

156 18549798 This defect is not due to reduced activation of STAT1 or STAT4 or to impaired upregulation of the transcription factor T-bet.
157 18549798 Instead, we find that T-bet binding to the Ifng promoter is greatly diminished in the absence of Jak3-dependent signals, correlating with a decrease in Ifng promoter accessibility and histone acetylation.

244 19828627 Ikaros is a regulator of Il10 expression in CD4+ T cells.
245 19828627 Here we show that Ikaros, a zinc finger DNA-binding protein, plays an important role in the regulation of Il10 in murine CD4(+) T cells.
246 19828627 Upon initial stimulation of the TCR, T cells deficient in Ikaros express significantly lower levels of IL-10 compared with wild-type T cells.
247 19828627 In addition, under Th2 skewing conditions, which induce IL-10 production by wild-type T cells, Ikaros null T cells are unable to properly differentiate, producing only low levels of IL-10.
248 19828627 Expression of a dominant-negative isoform of Ikaros in wild-type Th2 cells represses IL-10 production but does not significantly alter expression levels of the genes encoding the transcription factors GATA-3 and T-bet.
249 19828627 Furthermore, expression of Ikaros in Ikaros null T cells restores expression of the Th2 cytokines IL-10 and IL-4 while reducing production of the Th1 cytokine, IFN-gamma.
250 19828627 Coexpression of Ikaros and GATA-3 further increases IL-10 production, showing that these two factors have an additive effect on activating Il10 expression.
251 19828627 Finally, we show that Ikaros binds to conserved regulatory regions of the Il10 gene locus in Th2 cells, supporting a direct role for Ikaros in Il10 expression.
252 19828627 Thus, we provide evidence for Ikaros as a regulator of Il10 and Ifng gene expression and suggest a role for Ikaros in directing lineage-specific cytokine gene activation and repression.

280 19879772 TGF-beta1 experience by cells leads to sustained long-term inactivation of TNFalpha/IL-18-mediated cell activation but not IL-18 induced p38 activation suggesting transcriptional silencing of the T-BET and/or IFNG promoter independent of MAPK signalling.
281 20399120 The transcription factor GATA3 actively represses RUNX3 protein-regulated production of interferon-gamma.
282 20399120 The transcription factor GATA3 is crucial for the differentiation of naive CD4(+) T cells into T helper 2 (Th2) cells.
283 20399120 Here, we show that deletion of Gata3 allowed the appearance of interferon-gamma (IFN-gamma)-producing cells in the absence of interleukin-12 (IL-12) and IFN-gamma.
284 20399120 Such IFN-gamma production was transcription factor T-bet independent.
285 20399120 Another T-box-containing transcription factor Eomes, but not T-bet, was induced both in GATA3-deficient CD4(+) T cells differentiated under Th2 cell conditions and in Th2 cells with enforced Runx3 expression, contributing to IFN-gamma production.
286 20399120 GATA3 overexpression blocked Runx3-mediated Eomes induction and IFN-gamma production, and GATA3 protein physically interacted with Runx3 protein.
287 20399120 Furthermore, we found that Runx3 directly bound to multiple regulatory elements of the Ifng gene and that blocking Runx3 function in either Th1 or GATA3-deficient "Th2" cells results in diminished IFN-gamma production by these cells.
288 20399120 Thus, the Runx3-mediated pathway, actively suppressed by GATA3, induces IFN-gamma production in a STAT4- and T-bet-independent manner.

299 20399120 Here, we show that deletion of Gata3 allowed the appearance of interferon-gamma (IFN-gamma)-producing cells in the absence of interleukin-12 (IL-12) and IFN-gamma.
300 20399120 Such IFN-gamma production was transcription factor T-bet independent.
301 20399120 Another T-box-containing transcription factor Eomes, but not T-bet, was induced both in GATA3-deficient CD4(+) T cells differentiated under Th2 cell conditions and in Th2 cells with enforced Runx3 expression, contributing to IFN-gamma production.

305 20921622 Enhanced cell cycle and metabolic activity was restricted to the acute phase of the response, but at all stages, HCMV-specific CD8+ T cells expressed the Th1-associated transcription factors T-bet (TBX21) and eomesodermin (EOMES), in parallel with continuous expression of IFNG mRNA and IFN-γ-regulated genes.
306 20921622 The cytolytic proteins granzyme B and perforin as well as the fractalkine-binding chemokine receptor CX3CR1 were found in virus-reactive cells throughout the response.
307 21095589 Jmjd3 and UTX play a demethylase-independent role in chromatin remodeling to regulate T-box family member-dependent gene expression.
308 21095589 In this study, we show that the H3K27 demethylases, Jmjd3 and UTX, mediate a functional interaction between the lineage-defining T-box transcription factor family and a Brg1-containing SWI/SNF remodeling complex.
309 21095589 Importantly, Jmjd3 is required for the coprecipitation of Brg1 with the T-box factor, T-bet, and this interaction is necessary for Ifng remodeling in differentiated Th1 cells.
310 21321581 Protection against diabetes was accompanied by histone hyperacetylation in pancreas and spleen, enhanced frequency of CD4(+) CD62L(+) cells in the spleen, reduction in cellular infiltration of islets, restoration of normoglycemia and glucose-induced insulin release by beta cells.
311 21321581 Activation of splenic T lymphocytes derived from protected mice in vitro with pharmacological agents that bypass the antigen receptor or immobilized anti-CD3 antibody resulted in enhanced expression of Ifng mRNA and protein without altering the expression of Il4, Il17, Il18, Inos and Tnfa genes nor the secretion of IL-2, IL-4, IL-17 and TNF-α proteins.
312 21321581 Consistently, expression of the transcription factor involved in Ifng transcription, Tbet/Tbx21 but not Gata3 and Rorgt, respectively, required for the transcription of Il4 and Il17, was upregulated in activated splenocytes of protected mice.
313 21480212 Rapamycin-sensitive signals control TCR/CD28-driven Ifng, Il4 and Foxp3 transcription and promoter region methylation.
314 21480212 Here, we report that both mTOR complex 1 and mTOR complex 2 are readily activated following TCR/CD28 engagement and are critical for early expression of Ifng, Il4 and Foxp3, and for effector T cell differentiation in the absence of polarizing cytokines.
315 21480212 While inhibition of mTOR complex 1 and cell division were evident at low doses of RAPA, inhibition of mTOR complex 2, Ifng, Il4 and Foxp3 expression, and T-cell polarization required higher doses and more prolonged treatments.
316 21480212 We found that while T-bet and GATA3 were readily induced following TCR/CD28 engagement, administration of RAPA delayed their expression, and interfered with the loss of DNA methylation within Ifng and Il4 promoter regions.
317 21518797 The lineage-defining factors T-bet and Bcl-6 collaborate to regulate Th1 gene expression patterns.
318 21518797 The T-box transcription factor T-bet is important for the differentiation of naive CD4(+) T helper cells (Th cells) into the Th1 phenotype.
319 21518797 In this study, we first identify Socs1, Socs3, and Tcf7 (TCF-1) as gene targets that are negatively regulated by T-bet.
320 21518797 Consistent with this, we identified two T-bet DNA-binding elements in the Socs1 promoter that are functionally used to down-regulate transcription in primary Th1 cells.
321 21518797 Furthermore, T-bet functionally recruits Bcl-6 to the Ifng locus in late stages of Th1 differentiation to repress its activity, possibly to prevent the overproduction of IFN-γ, which could result in autoimmunity.

342 21983879 T-bet orchestrates the differentiation of mature peripheral T-cells into interferon-γ (IFN-γ) and tumor necrosis factor-α producing CD4+ T-helper type I (Th1) and CD8+ T cytotoxic cells that are necessary for antiviral responses.
343 21983879 When IL-12 is produced by antigen-presenting cells, T-bet expression is induced, causing direct stimulation of ifng gene transcription while simultaneously acting as a transcriptional repressor of the IL4 gene, which then leads to Th1 dominance and T-helper type 2 differentiation blockade.
344 21983879 We found that treatment with a farnesyltransferase inhibitor tipifarnib reduced Th1 cytokines in LGL leukemia patient T-cells and blocked T-bet protein expression and IL-12 responsiveness in T-cells from healthy donors.

351 22019771 We used a gene panel of regulatory/inflammatory molecules (FOXP3, GATA3, IL10, TGFB1, TGFBR1/ TBX21, TNF and IFNG) to investigate the gene expression profile in peripheral blood mononuclear cells of renal-transplanted individuals experiencing OT compared to transplanted individuals not displaying OT and healthy individuals (HI).
352 22019771 OT subjects showed a predominant regulatory (REG) profile with higher gene expression of GATA3, FOXP3, TGFB1 and TGFB receptor 1 compared to the other groups.
353 22685315 Twist1 regulates Ifng expression in Th1 cells by interfering with Runx3 function.
354 22685315 A transcription factor network that includes STAT4, T-bet, and Runx3 promotes the differentiation of Th1 cells and inflammatory immune responses.

377 22685317 Naturally occurring effector CD8(+) T cells, with a KLRG1(hi) CD62L(lo) phenotype typical of short-lived effector CD8(+) T cells (SLECs), can be found in increased numbers in autoimmune-prone mice, most notably in mice homozygous for the san allele of Roquin.
378 22685317 When Roquin is mutated (Roquin(san)), effector CD8(+) T cells accumulate in a cell-autonomous manner, most prominently as SLEC-like effectors.
379 22685317 Excessive IFN-γ promotes the accumulation of SLEC-like cells, increases their T-bet expression, and enhances their granzyme B production in vivo.
380 22685317 This study identifies a novel mechanism that prevents accumulation of self-reactive cytotoxic effectors, highlighting the importance of regulating Ifng mRNA stability to maintain CD8(+) T cell homeostasis and prevent CD8-mediated autoimmunity.
381 22851706 In this study, we show that transcription of both mouse and human TMEVPG1 genes is Th1 selective and dependent on Stat4 and T-bet, transcription factors that drive the Th1 differentiation program.
382 22851706 Ifng expression is partially restored in Stat4-/-Tbx21-/- cells through coexpression of T-bet and Tmevpg1, and Tmevpg1 expression contributes to, but alone is not sufficient to, drive Th1-dependent Ifng expression.

385 23159227 Unlike ICOS and T-bet deficiency that failed to rescue several autoimmune manifestations, interferon-γ receptor (IFN-γR) deficiency prevented lupus development.
386 23668260 The infected mice displayed a significant up-regulation in the expression of chemokines (Cxcl1, Cxcl2 and Ccl2), numerous pro-inflammatory cytokines (Ifng, Il1b, Il6, and Il17f), as well as Il22 and a number of anti-microbial peptides (Defa1, Defa28, Defb1, Slpi and Reg3g) at the site(s) of infection.
387 23668260 However, CD4 T cells of the untreated and C. difficile-infected mice expressed similar levels of CD69 and CD25.
388 23668260 Neither tissue had up-regulated levels of Tbx21, Gata3 or Rorc.
389 23668260 They also displayed significantly higher phosphorylation of AKT and signal transducer and activator of transcription 3 (STAT3), an indication of pro-survival signalling.
390 23668260 These data underscore the local, innate, pro-inflammatory nature of the response to C. difficile and highlight eIF2α phosphorylation and the interleukin-22-pSTAT3-RegIIIγ axis as two of the pathways that could be used to contain and counteract the damage inflicted on the intestinal epithelium.
391 23761633 STAT4 and T-bet are required for the plasticity of IFN-γ expression across Th2 ontogeny and influence changes in Ifng promoter DNA methylation.
392 23761633 CD4(+) T cells developing toward a Th2 fate express IL-4, IL-5, and IL-13 while inhibiting production of cytokines associated with other Th types, such as the Th1 cytokine IFN- γ.
393 23761633 We now show that this flexibility ("plasticity") of cytokine expression is preceded by a loss of the repressive DNA methylation of the Ifng promoter acquired during Th2 polarization yet requires STAT4 along with T-box expressed in T cells.
394 23761633 Surprisingly, loss of either STAT4 or T-box expressed in T cells increased Ifng promoter CpG methylation in both effector and memory Th2 cells.
395 23761633 STAT4 and T-bet are required for the plasticity of IFN-γ expression across Th2 ontogeny and influence changes in Ifng promoter DNA methylation.

403 24120504 In biofunction assays, recombinant gCCL4 was found to induce chemotactic activity in the peripheral blood leukocytes of groupers and up-regulate the gene expressions of grouper TNFA1 (TNF-α1), TNFA2 (TNF-α2), IFNG (IFN-γ), MX, TBX21 (T-bet), CD8 (α and β chain).
404 24249741 SerpinB1 regulates homeostatic expansion of IL-17+ γδ and CD4+ Th17 cells.
405 24249741 Here, we show that IL-17A(+) γδ and CD4(+) Th17 cells are already expanded in the lungs of serpinb1a(-/-) mice at steady-state.
406 24249741 Both γδ and αβ(+) CD4(+) CCR6(+) T cells isolated from the lungs of naive serpinb1a(-/-) mice displayed a skewed transcriptional profile relative to WT cells, including increased Th17 signature transcripts [Il17a, l17f, and Rorc (RORγt)] and decreased Th1 signature transcripts [Ifng, Cxcr3, and Tbx21 (T-bet)] in γδ T cells.
407 24249741 In addition to the lung, IL-17A(+) γδ and CD4(+) Th17 cells were increased in the spleen of naive serpinb1a(-/-) mice, despite normal αβ and γδ T cell development in the thymus.
408 24249741 Within the γδ T cell compartment, loss of serpinb1a prompted selective expansion of Vγ4(+) and Vγ6/Vδ1(+) cells, which also displayed elevated expression of the proliferating cell nuclear antigen, Ki-67, and IL-17A.
409 24249741 Given that serpinb1a is preferentially expressed in WT IL-17A(+) γδ and CD4(+) Th17 cell subsets vis-à-vis other T cell lineages, our findings reveal a novel function of serpinB1 in limiting untoward expansion of lymphocytes with a Th17 phenotype.
410 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(-)).
411 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(-)).
412 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(+)).
413 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.
