Irf3 pathway
WebNov 20, 2024 · There are two identified AIDs in IRF3 located in the N- and C-terminal regions compared to one AID found in IRF5 and IRF7 ( 14, 101, 102 ). The IRF3 crystal structure in its latent (unstimulated or autoinhibited monomer) form revealed the hydrophobic surface and a region essential for CBP/p300 binding that is masked by the AID ( 14 ). WebIRF3 is activated and interacts with the apoptotic signaling pathway in the liver, leading us to hypothesize that IRF3 regu-lates apoptosis in hepatocytes. We further investigated whether IRF3 was required for hepatocyte apoptosis using the Fas cell surfac e death receptor (Fas)-activating anti-CD95 antibody, clone Jo2 (Jo2). Hepatocytes have a ...

WebMay 11, 2024 · To investigate the role of the cGAS-IRF3 pathway in mice, we fed mice the Lieber-DeCarli diet, a classic model for studying alcohol-induced liver injury . We found that protein levels of cGAS, TBK1, IRF3, and phosphorylated IRF3 (pIRF3) were elevated markedly in liver tissue of alcohol-fed mice (Fig. 1D). WebNov 21, 2024 · A plasmid expressing IRF3-5D (a constitutively active mutant of IRF3) was kindly provided by Professor John Hiscott, Lady Davis Institute for Medical Research, McGill University, and a TAP-tagged (tandem Strep and Flag epitopes) p65 expression plasmid was described elsewhere ( Pallett et al., 2024 ).

WebHowever, the mechanisms by which IRF3 causes ALD remain obscure.IRF3 is a constitutively expressed transcription factor that resides in the cytoplasm and dimerizes and translocates to the nucleus upon phosphorylation (6). Phosphorylated IRF3 induces IFN-β during viral infection, but may also contribute to inflammatory cytokine response to LPS (7). WebThese dual functions of IRF3 work in concert to mediate protective immunity against virus infection. These two pathways are activated differentially by the posttranslational modifications...
