Smad3 foxp3
Webb15 apr. 2015 · Smad3 plays a critical role in promoting regulatory T cell differentiation. TGF-β signaling activates Smad3 which, along with mTOR-induced NF-AT, contributes to the induction of Foxp3 by promoting acetylation of the FOXP3 enhancer. mTOR plays simultaneous roles of inducing specific effector T cell differentiation by enhancing STAT … WebbFollowing TGF-β stimulation of T cells, Smad3, although not Smad2 or Smad4, has been shown to rapidly bind the CNS1 region suggesting a role for this transcription factor in Foxp3 expression. However, a role for Smad2 and/or Smad4 is not precluded as in the absence of either protein induction of Foxp3 in response to TGF-β is reduced (at least in …

We found that both the levels of Foxp3 and p-JNK were markedly elevated by adenosine or agonist of adenosine (CGS21680), but … Webb13 dec. 2011 · It should be noted that Smad3 binds to the intronic enhancer 1 of Foxp3 locus and that this binding is required for histone acetylation and the function of the enhancer . Concurrently, a conserved Smad-binding element in the promoter of the Foxp3 gene, located −85 bp upstream of the transcriptional start site, was identified [ 27 ].
Webb20 aug. 2012 · We show that binding of Smad3 to the foxp3 enhancer is dispensable for T reg cell development in newborn and adult mice with the exception of the gut. The TGF-β–Smad pathway plays a central role in development, maintenance, survival, and function of T cells (Li and Flavell, 2008).
