Molecular Mechanisms Regulating TGF-β-Induced Foxp3 Expression

WebbFigure 9 TGF-β1 suppresses T-cell response of tilapia by initiating Smad3- and Foxp3-mediated transcriptional networks. Upon bacterial infection, the activated T cells of tilapia produce TGF-β1, which initiates TGF-βR/Smad axis and triggers nuclear input of Smad2/3. 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 ]. WebbThus, Smad3 is an important regulator in maintaining the balance between Treg and Th17 immune responses, which is supported by the findings that Smad3 deficiency resulted in defective Foxp3 induction but enhanced Th17 cell generation in vitro and in vivo . On the other hand, activation of TGF-β/Smad3 signaling may also promote renal inflammation. import export online course india
