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. … 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.
