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. WebNov 26, 2024 · Type I interferonopathies are caused by disturbances in intracellular nucleic acid metabolism or in cytosolic nucleic acid sensing pathways that induce an overproduction of type I IFNs, triggering autoimmunity . Cytosolic nucleic acid sensors such as cyclic GMP–AMP synthase and MDA5 recognize broken intracellular self-DNA …
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. WebAug 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 …

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 …
WebSep 16, 2014 · Endosomal and cytosolic nucleic acid receptors are important immune sensors required for the detection of infecting or replicating viruses. The intracellular location of these receptors allows viral recognition and, at the same time, avoids unnecessary immune activation to self-nucleic acids that are continuously released by dying host … sivas tobacco shopWebApr 18, 2024 · Cytosolic sensing of nucleic acids initiates tightly regulated programs to limit infection.
