Cgas/sting pathway
WebMay 27, 2024 · The cGAS-STING pathway is recently recognized as a critical cytosolic DNA sensing pathway. However, uncontrolled signaling leads to increased autophagy, inflammasome activation, and interferon expression with subsequent loss of tolerance to self-antigens. This is best exemplified by monogenic disorders of this pathway, in which … STING is an endoplasmic reticulum resident protein and has been shown to directly bind to a variety of different cyclic-di-nucleotides. STING is expressed broadly in numerous tissue types, of both immune and non-immune origin. STING was identified in murine embryonic fibroblasts, and is required for the type 1 interferon response in both immune and non-immune ce…

WebThe cGAS/STING pathway is a cytoplasmic DNA sensor, and activation of the cGAS/STING pathway leads to two independent downstream pathways: type I IFNs through IRF3 and proinflammatory responses through NFκB16. Both the IRF3- and NF-κB-dependent pathways lead to the production of inflammatory growth factors and … WebJun 22, 2024 · The cGAS-STING pathway is the central cellular cytosolic double-stranded DNA (dsDNA) sensor, allowing innate immune to respond to infections, inflammation, and cancer [8, 9]. Both intrinsic and extrinsic self-DNA sensing can contribute to its activation.

We first tested whether the three members of the Rb gene family (Rb, p107, p130) were important for cGAS-STING pathway activation. However, primary mouse macrophages with lentiviral short hairpin RNA–mediated depletion of each of …
WebThe cGAS-STING pathway is an endogenous pathway that detects tumors and initiates immune responses ; thus, host cGAS was required for the antitumor effect of the immune checkpoint inhibitor anti–PD-L1 in the B16 melanoma mouse model . Here, we used the Lewis lung carcinoma (LL2) tumor model to study the antitumor effect of STING … WebApr 5, 2024 · This stimulates organization of cytosolic cGAS onto the mtDNA-CAP, and subsequent activation of the cGAS-STING-IRF3 pathway. TGF-β is unable to induce conversion of HSC from a quiescent to a trans-differentiated phenotype in the absence of mtDNA, VDAC or STING. Trans-differentiation by TGF-β is blocked by a STING inhibitor …
