1 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.
2 15280353 The TBET and the IFNG genes, but not the IL18RAP gene, showed preferential acetylation of histones H3 and H4 during TH1 differentiation.
3 15280353 Histone H3 acetylation of IFNG and TBET genes occurred with different kinetics, however, and was distinctively regulated by cytokines.
4 15280353 Interleukin (IL)-12 and IL-18 enhanced the histone acetylation of the IFNG gene.
5 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.
6 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.
7 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.
8 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.
9 16520391 T-bet regulates Th1 responses through essential effects on GATA-3 function rather than on IFNG gene acetylation and transcription.
10 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.
11 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.
12 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.
13 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.
14 16520391 Finally, we show that retroviral T-bet expression in developing and established Th2 cells leads to down-regulation of GATA-3 levels.
15 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.
16 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.
17 17195845 Transcription factors T-bet and Runx3 cooperate to activate Ifng and silence Il4 in T helper type 1 cells.
18 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.
19 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.
20 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.
21 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.
22 19689734 A continuous T-bet expression is required to silence the interleukin-4-producing potential in T helper type 1 cells.
23 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.
24 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.
25 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.
26 19689734 To address this problem, we used an inducible form of T-bet - a T-bet-oestrogen receptor fusion molecule (T-bet-ER).
27 19689734 We found that the activation of T-bet during primary or secondary culture was sufficient to silence IL-4-producing potential.
28 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.
29 19689734 Additionally, we found that T-bet is required to maintain Ifng expression.
30 19689734 Our data demonstrate that the continuous expression of T-bet is required for Th1 cells to silence their IL-4-producing potential.
31 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.
32 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.
33 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.
34 21480212 Rapamycin-sensitive signals control TCR/CD28-driven Ifng, Il4 and Foxp3 transcription and promoter region methylation.
35 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.
36 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.
37 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.
38 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.
39 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.
40 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.
