Stat1 and ifn
WebSTAT1 and IRF9 are mediators of canonical interferon signaling, which is initiated upon the binding of IFN to the interferon receptor (IFNAR1/2). Interestingly, we found an increase in … WebJan 8, 2024 · In addition, STAT1 homodimers form the IFN-γ-activated factor (GAF) complex which binds to IFNg-activated sequences (GAS). Altogether, these transcription factors induce a broad spectrum of IFN-stimulated genes (ISG)s that mediate the complex “antiviral state” of IFNs. IRFs In mammals nine different IRF family members have been described.

However, the contribution of tonic levels of IFN to immune homeostasis in the absence of acute infection remains largely unexplored.
WebNational Center for Biotechnology Information WebIL-21 is a type I cytokine important for immune cell differentiation and function. We found that transcription factors STAT1 and STAT3 play partially opposing roles in IL-21 function in CD4 + T cells. Both STAT1 and STAT3 control IL-21–mediated gene regulation, with some genes, including Ifng, Tbx21, and Il21 reciprocally regulated by these STATs. IFN-γ …
WebMoreover, we confirm that IFN-γ mediates stat1 phosphorylation in monocytic cells . Figure 2 Synergistic expression of CCL2 is dependent on STAT1. (A) THP-1 monocytic cells were transfected with control/scrambled siRNA or STAT1 siRNA and incubated for 40h. Total RNA was extracted and real-time RT-PCR was performed to measure STAT1 mRNA …
WebAnother example of IFN-independent activity of STAT1 is the more severe impairment of natural killer cells caused by STAT1 deficiency than observed with deficiencies of both IFN-γ and IFN-α/β receptors. Because IFNs have antineoplastic activities, a role for STAT1 in tumor suppression has been suspected, and indeed, STAT1-deficient mice have ... ls 後期 シーケンシャルWebIn vitro, IFN-γ gene expression as well as amplification of downstream STAT1 and inducible nitric oxide synthase (iNOS; a hallmark of ischemia reperfusion injury) was remarkably increased after CS + rewarming.
