WebJan 1, 2024 · Central to the autoinflammatory and autoimmune disorders discussed in this review are the sensors that detect cytosolic nucleic acids to stimulate an innate immune response. The primary role of the innate immune system is to be the first line of defense against foreign microbes. The recognition of microbes and nucleic acid depends on … WebEngagement of innate cytosolic sensors in turn activates key signaling adaptor proteins including mitochondrial antiviral signaling (MAVS) or stimulator of IFN genes (STING), which drive IFN-β production. How extracellular nucleic acids engage cytosolic sensors is incompletely understood.
WebMar 1, 2024 · Cytosolic Nucleic Acid Sensing Pathways RIG-I-Mediated Sensing of Cytosolic RNA. RIG-I-like receptors (RLRs) are responsible for the detection of single-stranded (ss) and double-stranded (ds) RNA generated in the course of a virus infection [6].This receptor family contains three members: RIG-I, melanoma differentiation … WebPRRs that recognize nucleic acids in cells include several endosomal members of the Toll-like receptor family and several cytosolic sensors for DNA and RNA. Here, we review …
WebThe Hippo pathway senses cellular conditions and regulates YAP/TAZ to control cellular and tissue homeostasis, while TBK1 is central for cytosolic nucleic acid sensing and antiviral defence. The correlation between cellular nutrient/physical status and host antiviral defence is interesting but not well understood. 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.
WebOct 29, 2024 · NLRP14-mediated inhibition of cytosolic nucleic acid sensing. Upon activation of STING dependent signaling, conformational rearrangement from inhibitory-form to an active-form of NLRP14 is induced. Targeting of TBK1 for K48-linked poly-ubiquitination is then initiated and results in proteasome dependent degradation of TBK1 and …
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.
