Stat4 phosphorylation
WebIL-12 acts via the STAT4 signaling pathway. Signal transduc-tion through the IL-12 receptor (IL-12R) induces tyrosine phosphorylation of the Janus family kinases JAK2 and TYK2, which in turn phosphorylate STAT4 [3]. Phosphorylated STAT4 (pSTAT4) dimerizes, translocates to the nucleus, and instigates DNA transcription [4]. IL-12 is critical in ... WebSystemic scleroderma. A normal variation in the STAT4 gene has been associated with an increased risk of developing systemic scleroderma, which is an autoimmune disorder …

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). WebJan 1, 1999 · Similarly, STAT4 activation in response to IL-2 was not affected by the presence of an Ab against the β1 subunit of the IL-12R (12Rβ44), which could block the ability of IL-12 to activate STAT4 phosphorylation (Fig. 3 B). These results indicate that the STAT4 activation in response to IL-2 is not due to exogenous stimulation with IL-12 or IFN …
WebIL-33 does not interfere IL-12 STAT4 phosphorylation. Human NK cells were left untreated (UT) or incubated with IL-12 or IL-33 for 10–120 min prior to phosphoflow measurement of phosphorylated STAT4 levels. Representative histogram plots are shown (1 of 5 similar experiments using cells from different donors), along with graphs of median ... WebWe then transfected STAT4 plasmids into HOKs and found STAT4 overexpression has no effect on IL-17 transcription and expression (Figures S5E–S5G), indicating that the overexpression, itself, of STAT4 is not sufficient to induce IL-17 expression and that phosphorylation may be a key event that allows for STAT4’s induction of IL-17 expression.
