Opposing roles of STAT4 and Dnmt3a in Th1 gene regulation.
The STAT transcription factor STAT4 is a critical regulator of Th1 differentiation and inflammatory disease. Yet, how STAT4 regulates gene expression is still unclear. In this report, we define a STAT4-dependent sequence of events including histone H3 lysine 4 methylation, Jmjd3 association with STAT4 target loci, and a Jmjd3-dependent decrease in histone H3 lysine 27 trimethylation and DNA met...
متن کاملSignal transducer and activator of transcription 4 is required for the transcription factor T-bet to promote T helper 1 cell-fate determination.
Transcriptional regulatory networks direct the development of specialized cell types. The transcription factors signal tranducer and activator of transcription 4 (Stat4) and T-bet are required for the interleukin-12 (IL-12)-stimulated development of T helper 1 (Th1) cells, although the hierarchy of activity by these factors has not been clearly defined. In this report, we show that these factor...
متن کاملImpaired development of human Th1 cells in patients with deficient expression of STAT4.
IL-12 activates STAT4, which is a critical regulator of inflammation and T helper type I (Th1) lineage development in murine systems. The requirement for STAT4 in the generation of human Th1 cells has not been examined thoroughly. Compared with control Th1 cultures, expression of the Th1 genes IFNgamma, IL-12Rbeta2, and TNFalpha is greatly reduced in Th1 cultures of CD4 T cells isolated from ly...
متن کاملThe Ets transcription factor ERM is Th1-specific and induced by IL-12 through a Stat4-dependent pathway.
Interleukin 12 (IL-12)-induced T helper 1 (Th1) development requires Stat4 activation. However, antigen-activated Th1 cells can produce interferon gamma (IFN-gamma) independently of IL-12 and Stat4 activation. Thus, in differentiated Th1 cells, factors regulated by IL-12 and Stat4 may be involved in IFN-gamma production. Using subtractive cloning, we identified ERM, an Ets transcription factor,...
متن کاملStat4 is critical for the balance between Th17 cells and regulatory T cells in colitis.
Th17 play a central role in autoimmune inflammatory responses. Th1 are also necessary for autoimmune disease development. The interplay of Th1 signals and how they coordinate with Th17 during inflammatory disease pathogenesis are incompletely understood. In this study, by adding Stat4 deficiency to Stat6/T-bet double knockout, we further dissected the role of Stat4 in Th1 development and coliti...
