WebMar 11, 2024 · Toll-like receptor (TLR) and cyclic GMP-AMP synthase (cGAS)-stimulator of IFN genes (STING) pathways are major DNA recognition factors. Upon DNA binding, cGAS synthesizes 2'3'-cGAMP that binds to STING, resulting in TANK-binding kinase (TBK)1 and IFN regulatory factor (IRF) 3 activation via a phosphorylation-dependent mechanism. ... WebApr 1, 2024 · The cGAS activates the cGAS–STING–type I IFN signaling pathway to promote the priming of T-cells in regional lymph nodes. Furthermore, the type I IFN signaling pathway promotes the intratumoral infiltration of CD8 + T-cells via C-X-C motif chemokine ligand 10 (CXCL10), which is induced by type I IFN ( Figure 2 ) [ 11 , 12 ].
WebThe cyclic GMP-AMP synthase-stimulator of the IFN genes (cGAS-STING) pathway is constitutively activated in a subset of cancer cells in the presence of high levels of PD-L1, thus leading to a constitutive, low level of IFN-β expression, which in …
WebMay 23, 2024 · However, fusion between RNA viral envelopes and target cells also specifically stimulates a type I IFN response which is dependent on STING, but independent of DNA, RNA and viral capsid. STING, which is part of the complex cGAS/STING, localizes to the endoplasmic reticulum membrane in basal conditions, and is activated by cGAMP. WebApr 12, 2024 · Numerous studies highlighted the importance of the cGAS-STING-TBK1-type I IFN pathway in antitumor immunity. Meanwhile, JmjC domain-containing proteins have been widely implicated in cancer development. However, the involvement of the JmjC domain-containing protein family in STING-mediated type I IFN responses and the …
WebSep 18, 2024 · Besides induction of IFN and other cytokines, the cGAS-STING pathway is also able to initiate autophagy and this has been shown to limit replication of viruses, such as the human immunodeficiency virus or herpes virus simplex 1, and intracellular bacteria, such as Mycobacterium tuberculosis (14, 15). How this function contributes to pathogen ...
