WebJul 18, 2014 · In this Progress article, we describe the recent studies that have revealed the existence of a new family of cytosolic nucleic acid-sensing proteins that includes the well-known dsRNA-sensing... WebNucleic acids, which are essential genetic information carriers for all living organisms including viral, bacterial, and eukaryotic pathogens, are major structures detected by the innate immune system. However, inappropriate detection of self nucleic acids can result in autoimmune diseases.
WebJan 1, 2024 · In general, nucleic acid sensing by multiple PRRs can trigger activation of type I IFNs, inflammasome, and other inflammatory signaling pathways. As seen with … 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 …
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 … 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 …
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 ...
WebThe nucleic acid–sensing PRRs are localized at the plasma membrane, the cytosol, and/or various cellular organelles. Sensing of nucleic acids and signaling by PRRs involve recruitment of distinct signaling components, and PRRs are intensively regulated by cellular organelle trafficking. easton pa to buffalo nyWebHere, we review recent progress in innate immune recognition of nucleic acids upon microbial infection, including pathways involving endosomal Toll-like receptors, cytosolic RNA sensors, and cytosolic DNA sensors. We also discuss the mechanisms by which infectious microbes counteract host nucleic acid sensing to evade immune surveillance. easton pa to flemington njWebApr 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. easton pa to hackensack njWebAug 16, 2024 · Thus, the lack of cytosolic nucleic acid sensing leads to a transient increase in IL-6 production and signalling during the first few hours after partial … culver power chairWebBoth endosomal and cytosolic-nucleic acid-sensing receptors can detect endogenous ligands and promote autoimmunity and autoinflammation.
