Targeting of the cGAS-STING system by DNA viruses.

Targeting of the cGAS-STING system by DNA viruses. Biochem Pharmacol. 2020 Jan 28;:113831 Authors: Phelan T, Little MA, Brady G Abstract Innate sensing of viruses by cytosolic nucleic acid sensors is a key feature of anti-viral immunity against these pathogens. The DNA sensing pathway through the sensor cyclic GMP-AMP synthase (cGAS) and its downstream effector stimulator of interferon genes (STING) has emerged in recent years as a key, front-line means of driving interferons and pro-inflammatory cytokines in response to DNA virus infection in vertebrates. Unsurprisingly, many DNA viruses have evolved effective inhibitors of this signalling system which target at a wide variety of points from sensing all the way down to the activation of Interferon Regulatory Factor (IRF)-family and Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-family transcription factors which drive a program of pro-inflammatory and anti-viral gene expression. Here we review DNA viruses that have been shown to inhibit this pathway and the inhibitors they have evolved to do it. PMID: 32004549 [PubMed - as supplied by publisher]
