WebApr 18, 2024 · Cytosolic sensing of nucleic acids initiates tightly regulated programs to limit infection. Oocyte fertilization represents a scenario wherein inappropriate responses to exogenous yet non-pathogen-derived nucleic acids would have negative consequences. Web1 language. The cGAS–STING pathway is a component of the innate immune system that functions to detect the presence of cytosolic DNA and, in response, trigger expression of inflammatory genes that can lead to senescence [1] or to the activation of defense mechanisms. DNA is normally found in the nucleus of the cell.
WebApr 21, 2011 · While recognition of RNA molecules is dependent on members of the TLR family and cytosolic RNA helicases, the mechanisms underlying the sensing of DNA have been less well defined. It has been known for over a decade that DNA, the most recognizable unit of life, is a potent trigger of inflammatory responses in cells. WebMay 12, 2014 · The cytosolic nucleic acid sensing by DHX29 in human epithelial cells and fibroblasts is independent of stimulator of interferon genes but is dependent on retinoic acid-inducible gene 1 (RIG-I) and mitochondrial antiviral signaling protein (MAVS). DHX29 binds directly to nucleic acids and interacts with RIG-I and MAVS through its helicase 1 ...
