1 12447360 We found that in these conditions human naive T cells acquired stable histone hyperacetylation at either the Ifng or Il4 promoter.
2 12447360 Such cytokine flexibility was absent in a subset of T(H)2 cells that failed to up-regulate T-bet and to express interferon-gamma when stimulated under T(H)1 conditions.
3 15183000 This publication describes the cloning of full or partial length sequences for pig TBX21 (T-bet), MYD88, ICSBP1, CD8A (CD8alpha), CD8B (CD8beta), and CD28 cDNAs.
4 15183000 Real-time PCR assays have been developed for the relative quantitation of these products as well as previously characterized transcripts that encode exon A-containing CD45, HLX1, IRF1, STAT1 and RPL32.
5 15183000 When used for examining temporal immune gene expression in the liver of Toxoplasma gondii infected pigs, the positive regulators of Th1 responses, IRF1, MYD88, and STAT1, were found to be expressed prior to the simultaneous upregulation of interferon gamma (IFNG), HLX1 and TBX21 gene expression.
6 15183000 In contrast, in the mesenteric lymph node (MLN), only expression of IRF1 and IFNG was significantly upregulated.
7 15241679 Therefore, we focused on the Th1-specific T-box transcription factor gene (T-bet), which contributes to the induction of the hallmark Th1 cytokine, IFN-gamma.
8 15241679 Furthermore, Gln33 T-bet showed a significantly higher transcriptional activity of the IFNG gene via a dual luciferase reporter assay.
9 15241679 Our study suggests the first evidence of an association between type 1 diabetes and polymorphisms in the T-bet gene, and that variation in T-bet transcriptional activity may play a role in the development of type 1 diabetes, possibly through the effect on IFN-gamma production in Th1 cells.
10 15280353 To better understand the control of T helper (TH) 1-expressed genes, we compared and contrasted acetylation and expression for three key genes, IFNG, TBET, and IL18RAP and found them to be distinctly regulated.
11 15280353 The TBET and the IFNG genes, but not the IL18RAP gene, showed preferential acetylation of histones H3 and H4 during TH1 differentiation.
12 15280353 Histone H3 acetylation of IFNG and TBET genes occurred with different kinetics, however, and was distinctively regulated by cytokines.
13 15280353 Interleukin (IL)-12 and IL-18 enhanced the histone acetylation of the IFNG gene.
14 15280353 By contrast, histone acetylation of the TBET gene was markedly suppressed by IL-4, whereas IL-12 and IL-18 had only modest effects suggesting that histone acetylation during TH1 differentiation is a process that is regulated by various factors at multiple levels.
15 15280353 By treating Th2 cells with a histone deacetylase inhibitor, we restored histone acetylation of the IFNG and TBET genes, but it did not fully restore their expression in TH2 cells, again suggesting that histone acetylation explains one but not all the aspects of TH1-specific gene expression.
16 15304658 When linked to the murine Ifng gene (-3.4 to +5.6 kb) and transiently transfected into EL-4 cells, these elements clearly enhanced IFN-gamma expression in response to ionomycin and phorbol 12-myristate 13-acetate and weakly enhanced expression in response to T-bet.
17 15304658 A DNase I hypersensitive site and extragenic transcripts at IFNgCNS2 correlated positively with the capacity of primary T cell subsets to produce IFN-gamma.
18 15304658 Transcriptionally favorable histone modifications in the Ifng promoter, intronic regions, IFNgCNS2, and, although less pronounced, IFNgCNS1 increased as naïve T cells differentiated into IFN-gamma-producing effector CD8+ and T helper (TH) 1 T cells, but not into TH2 T cells.
19 15304658 Like IFN-gamma expression, these histone modifications were T-bet-dependent in CD4+ cells, but not CD8+ T cells.
20 16237092 Using conditional introduction of dominant-negative factors, we now show that T-bet and GATA-3 are far more critical in establishment than maintenance of IFN-gamma and IL-4 activity during Th1 and Th2 maturation, respectively.
21 16237092 T-bet plus Hlx can disrupt ifng silencing when introduced into developing Th2 cells, but they fail to perturb ifng silencing in mature Th2 cells.
22 16520391 T-bet regulates Th1 responses through essential effects on GATA-3 function rather than on IFNG gene acetylation and transcription.
23 16520391 T helper type 1 (Th1) development is facilitated by interrelated changes in key intracellular factors, particularly signal transducer and activator of transcription (STAT)4, T-bet, and GATA-3.
24 16520391 Here we show that CD4+ cells from T-bet-/- mice are skewed toward Th2 differentiation by high endogenous GATA-3 levels but exhibit virtually normal Th1 differentiation provided that GATA-3 levels are regulated at an early stage by anti-interleukin (IL)-4 blockade of IL-4 receptor (R) signaling.
25 16520391 In addition, under these conditions, Th1 cells from T-bet-/- mice manifest IFNG promotor accessibility as detected by histone acetylation and deoxyribonuclease I hypersensitivity.
26 16520391 In related studies, we show that the negative effect of GATA-3 on Th1 differentiation in T-bet-/- cells arises from its ability to suppress STAT4 levels, because if this is prevented by a STAT4-expressing retrovirus, normal Th1 differentiation is observed.
27 16520391 Finally, we show that retroviral T-bet expression in developing and established Th2 cells leads to down-regulation of GATA-3 levels.
28 16520391 These findings lead to a model of T cell differentiation that holds that naive T cells tend toward Th2 differentiation through induction of GATA-3 and subsequent down-regulation of STAT4/IL-12Rbeta2 chain unless GATA-3 levels or function is regulated by T-bet.
29 16520391 Thus, the principal function of T-bet in developing Th1 cells is to negatively regulate GATA-3 rather than to positively regulate the IFNG gene.
30 17195845 Transcription factors T-bet and Runx3 cooperate to activate Ifng and silence Il4 in T helper type 1 cells.
31 17195845 Here we show that the transcription factor Runx3 is induced in T helper type 1 (T(H)1) cells in a T-bet-dependent manner, and that both transcription factors T-bet and Runx3 are required for maximal production of interferon-gamma (IFN-gamma) and silencing of the gene encoding interleukin 4 (Il4) in T(H)1 cells.
32 17195845 T-bet does not repress Il4 in Runx3-deficient T(H)2 cells, but coexpression of Runx3 and T-bet induces potent repression in those cells.
33 17195845 Both T-bet and Runx3 bind to the Ifng promoter and the Il4 silencer, and deletion of the silencer decreases the sensitivity of Il4 to repression by either factor.
34 17195845 Our data indicate that cytokine gene expression in T(H)1 cells may be controlled by a feed-forward regulatory circuit in which T-bet induces Runx3 and then 'partners' with Runx3 to direct lineage-specific gene activation and silencing.
35 18549798 Janus-kinase-3-dependent signals induce chromatin remodeling at the Ifng locus during T helper 1 cell differentiation.
36 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).
37 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.
38 18549798 In the absence of Jak3-dependent signals, naive CD4+ T cells proliferate robustly but produce little IFN-gamma after Th1 cell polarization in vitro.
39 18549798 This defect is not due to reduced activation of STAT1 or STAT4 or to impaired upregulation of the transcription factor T-bet.
40 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.
41 18549798 These data indicate that Jak3 regulates epigenetic modification and chromatin remodeling of the Ifng locus during Th1 cell differentiation.
42 19332534 Ascaris-infected pigs had increased levels of liver mRNA for T-helper-2 (Th2)-associated cytokines, mast cell markers, and T regulatory (Treg) cells, while infected pigs given ATRA had higher IL4, IL13, CCL11, CCL26, CCL17, CCL22, and TPSB1 expression.
43 19332534 Gene expression for Th1-associated markers (IFNG, IL12B, and TBX21), the CXCR3 ligand (CXCL9), IL1B, and the putative Treg marker TNFRSF18 was also increased.
44 19332534 Expression of IL4, IL13, IL1B, IL6, CCL11, and CCL26 was increased in the lungs of infected pigs treated with ATRA.
45 19332534 IL4 induced CCL11, CCL17, CCL22, and CCL26 mRNA, and ATRA increased the basal and IL4-stimulated expression of CCL17 and CCL22.
46 19384057 Recently, we reported a novel mechanism by which the T-box transcription factor T-bet interacts with JMJD3, an H3K27-demethylase, and Set7/9, an H3K4-methyltransferase (Genes Dev. 2008. 22: 2980-2993).
47 19384057 Therefore, studies examining the molecular mechanisms that account for the ability of T-bet to regulate Ifng and Cxcr3, prototypic CD4+ Th1 genes, have provided novel insight into essential regulatory events that occur at diverse developmental transitions.
48 19464989 In this issue of Immunity, Schulz et al. (2009) use mathematical modeling to elucidate a signaling network controlling Ifng gene expression, thereby showing the importance of an Interleukin-12-dependent, Interferon-gamma-independent second phase of inducing the transcription factor T-bet.
49 19689734 A continuous T-bet expression is required to silence the interleukin-4-producing potential in T helper type 1 cells.
50 19689734 To develop into committed T helper type 1 (Th1) cells, naive CD4(+) T cells not only need to acquire the capacity to produce interferon-gamma (IFN-gamma), but they also need to gain the ability to silence their interleukin-4 (IL-4) -producing potential.
51 19689734 We found that a lack of IL-4 stimulation was not sufficient to silence the IL-4-producing potential in activated CD4(+) T cells and that Th1-promoting factor was required.
52 19689734 Although it has been shown that T-bet is a crucial factor in suppressing Il4 gene expression, it is unclear whether a continuous presence of T-bet is required to silence the Il4 gene in Th1 cells.
53 19689734 To address this problem, we used an inducible form of T-bet - a T-bet-oestrogen receptor fusion molecule (T-bet-ER).
54 19689734 We found that the activation of T-bet during primary or secondary culture was sufficient to silence IL-4-producing potential.
55 19689734 On the other hand, the inactivation of T-bet after naïve CD4(+) T cells had differentiated into Th1 cells resulted in derepression of Il4 gene transcription.
56 19689734 Additionally, we found that T-bet is required to maintain Ifng expression.
57 19689734 Our data demonstrate that the continuous expression of T-bet is required for Th1 cells to silence their IL-4-producing potential.
58 19879772 TNFalpha and TGF-beta1 influence IL-18-induced IFNgamma production through regulation of IL-18 receptor and T-bet expression.
59 19879772 IL-18 is a pro-inflammatory cytokine that drives dendritic cell maturation and mediates IFNgamma production.
60 19879772 In this study, we demonstrate that in the dendritic precursor-like cell line KG-1, IFNgamma production induced by IL-18 is potentiated (>5-fold) by TNFalpha and completely suppressed by TGF-beta1.
61 19879772 IL-18 stimulation rapidly activates different MAPK signalling pathways but only blocking of p38 activation alleviates IFNgamma production.
62 19879772 The mechanism through which TNFalpha enhances IL-18 induced IFNgamma production is by promoting IL-18 receptor alpha-chain expression which results in higher levels of p38 activation and induces expression of T-bet, a transcriptional regulator of the IFNG gene.
63 19879772 In contrast, TGF-beta1 rapidly suppresses IFNgamma production by limiting IL-18 receptor numbers at the cell surface and preventing induction of T-bet expression.
64 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.
65 20399120 The transcription factor GATA3 actively represses RUNX3 protein-regulated production of interferon-gamma.
66 20399120 The transcription factor GATA3 is crucial for the differentiation of naive CD4(+) T cells into T helper 2 (Th2) cells.
67 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.
68 20399120 Such IFN-gamma production was transcription factor T-bet independent.
69 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.
70 20399120 GATA3 overexpression blocked Runx3-mediated Eomes induction and IFN-gamma production, and GATA3 protein physically interacted with Runx3 protein.
71 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.
72 20399120 Thus, the Runx3-mediated pathway, actively suppressed by GATA3, induces IFN-gamma production in a STAT4- and T-bet-independent manner.
73 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.
74 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.
75 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.
76 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.
77 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.
78 21480212 Rapamycin-sensitive signals control TCR/CD28-driven Ifng, Il4 and Foxp3 transcription and promoter region methylation.
79 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.
80 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.
81 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.
82 21518797 The lineage-defining factors T-bet and Bcl-6 collaborate to regulate Th1 gene expression patterns.
83 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.
84 21518797 In this study, we first identify Socs1, Socs3, and Tcf7 (TCF-1) as gene targets that are negatively regulated by T-bet.
85 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.
86 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.
87 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).
88 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.
89 22685315 Twist1 regulates Ifng expression in Th1 cells by interfering with Runx3 function.
90 22685315 A transcription factor network that includes STAT4, T-bet, and Runx3 promotes the differentiation of Th1 cells and inflammatory immune responses.
91 22685315 In this study we show that the negative regulatory factor Twist1 decreases expression of T-bet, Runx3, and IL-12Rβ2 as it inhibits IFN-γ production.
92 22685315 Ectopic expression of Runx3, but not T-bet or IL-12Rβ2, compensates for the effects of Twist1 on IFN-γ production, and Twist1 regulation of Ifng depends on complex formation with Runx3.
93 22685315 Twist1 decreases Runx3 and T-bet binding at the Ifng locus, and it decreases chromatin looping within the Ifng locus.
94 22685315 These data define an IL-12/STAT4-induced negative regulatory loop that impacts multiple components of the Th1 transcriptional network and provide further insight into regulation of Th1 differentiation.
95 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.
96 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.
97 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.
98 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.
99 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.
100 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.
101 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).
