STING-IRF3 Triggers Endothelial Inflammation in … WebThe sensors cGAS and RIG-I recognize different nucleic acids and signal through distinct adaptors. cGAS senses the aberrant presence and concentration of DNA in the cytosol then recruits stimulator of interferon genes (STING, or MITA/ERIS/MPYS) through the cyclic dinucleotide 2’3’cGAMP 2.
WebThe cGAS-STING pathway is important in microbial infection, autoimmune diseases, and cancer (Tao et al. 2016). DNA within the cytosol can be an indicator of pathogen invasion and is sensed by cyclic GMP-AMP synthase (cGAS). Mitochondrial DNA (mtDNA) can also serve as a cGAS ligand in a certain context (Ma et al. 2024).
WebMammalian cells detect DNA viruses through the cGAS–STING pathway . cGAS recognizes cytoplasmic DNA and generates 2′, 3′-Cyclic guanosine monophosphate–adenosine monophosphate (cGAMP), an intracellular second messenger that directly binds to and activates STING to induce the transcription of IRF3- and NF-κB–dependent genes, … cost colonoscopy without insuranceWebJan 29, 2015 · In contrast, activation of the RIG-I–MAVS and cGAS-STING pathways through vesicular stomatitis virus (VSV) infection and herring testis DNA (HT-DNA) transfection, respectively, leads to activation of IKK and TBK1, as well as IRF3 (fig.
