Reciprocal effects of IFN- and IL-12 on STAT4 …

Pro-inflammatory cytokine IL-12 is produced in heterodimer form by B cells and antigen-presenting cells. Binding of IL-12 to IL-12R, which is composed of two different subunits (IL12Rβ1 and IL12Rβ2), leads to the interaction of IL12Rβ1 and IL12Rβ2 with JAK2 and TYK2, which is followed by phosphorylation of STAT4 tyrosine 693. The pathway then induces IFNγ production and Th1 differentiation.

WebSTAT4, phosphorylated in Tfh cells upon infection, is required for expression of T-bet and Bcl6 and for IFN-γ and IL-21. These data indicate that T-bet is expressed with Bcl6 in Tfh cells and is required alongside STAT4 to coordinate Tfh cell IL-21 and IFN-γ production and for promotion of the GC response after acute viral challenge. Introduction WebPhosphorylated STAT4 in cTfh cells and CD4 + T memory cells were analyzed as previously described . Isolated PBMCs were rested and then stimulated by IFN-β (1000 U/ml) or IL-12 (10 ng/ml) for 20 minutes in DMEM with 1% serum. Stimulated cells were immediately fixed with 4% paraformaldehyde for 15 min, then cold methanol was used to ...

WebSTAT4/ mice, suggesting a pivotal role for macrophages in mediating protection against cysticercosis. These findings demonstrate a critical role for the STAT4 signaling pathway in the development of a Th1-type immune response that is essential for mediating protection against the larval stage of T. crassiceps infection. WebJan 1, 1999 · STAT4 has been reported to be activated only in response to IL-12 in NK cells and T cells ( 24, 25, 26 ), and IFN-α in NK3.3 cells ( 24 ). Although IL-2 treatment of NK cells is not known to lead to production of IL-12 or IFN-α, we considered the possibility that autocrine production of one of these factors might lead to STAT4 phosphorylation.

WebSep 1, 2024 · Given the strong connection between prolonged T1IFN/IFNAR-induced STAT4 activation and lysosomal mTORC1 activation only in Stat1 −/− CD8 + T cells, it is tempting to speculate that the similar phenomena may also occur in WT CD8 + T cells by IL-12/IL-12R engagement, as this cytokine induces STAT4, but not STAT1, activation.
