Cytosolic nucleic acid-sensing pathways
Did you know?
WebMicrobial nucleic acids are major signatures of invading pathogens, and their recognition by various host pattern recognition receptors (PRRs) represents the first step toward an efficient innate immune response to clear the pathogens. The nucleic acid–sensing PRRs are localized at the plasma membrane, the cytosol, and/or various cellular organelles. … WebSep 9, 2024 · Cytosolic nucleic acid detection pathways have been vastly explored in vitro (in immune and nonimmune cell types) and in vivo, mostly focusing on murine models. However, recent work underscores the existence of cell-type-dependent and species-specific detection mechanisms, urging for re-evaluation of nucleic acid sensing in …

LV and AAV have been reported to activate TLR signalling (TLR9 and 7) at the endosomal level, thus leading to Myd88-mediated IRF activation.... WebThe cGAS – STING pathway acts to detect cytosolic DNA and induce an immune response. Upon binding DNA, the protein cyclic GMP-AMP Synthase ( cGAS) triggers reaction of GTP and ATP to form cyclic GMP-AMP (cGAMP). cGAMP binds to Stimulator of Interferon Genes ( STING) which triggers phosphorylation of IRF3 via TBK1.
WebSep 20, 2024 · cGAS is a kind of cytosolic DNA sensor which initiates innate immune (Fig. 1 ). Notably, cGAS and its downstream regulators form a major DNA-sensing mechanism, sensing foreign and self-DNA in the cytoplasm and sometimes in the micronucleus and nuclei as well [ 8 ].
