WebSep 15, 2007 · IFN-alpha did not promote Th1 development in human CD4+ T cells because of attenuated STAT4 phosphorylation, which was insufficient to induce stable expression of T-bet. Further, the defect in IFN-alpha-driven Th1 development was corrected by ectopic expression of T-bet within primary naive human CD4+ T cells. WebSTAT, recruited to the receptor complex, is then phosphorylated at a tyrosine residue by the JAKs. This tyrosine phosphorylation promotes STAT homo and heterodimerization mediated by reciprocal phosphotyrosine SH2 domain interaction and the dissociation of the dimers from the receptor complex (D). difference between nx 250 and nx 350
