WebOct 6, 2024 · As viruses have a capacity to rapidly evolve and continually alter the coding of their protein repertoires, host cells have evolved pathways to sense viruses through the one invariable feature common to all these pathogens—their nucleic acids. These genomic and transcriptional pathogen-associated molecular patterns (PAMPs) trigger the … WebApr 11, 2024 · Recently, phase separation has been identified in different immune signaling pathways, of which cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling is an important ...
Cytosolic and nuclear recognition of virus and viral evasion
WebDec 9, 2016 · Protect this house: cytosolic sensing of viruses: Abstract: The ability to recognize invading viral pathogens and to distinguish their components from those of the host cell is critical to initiate the innate immune response. The efficiency of this detection is an important factor in determining the susceptibility of the cell to viral infection. WebCytosolic receptors that sense viruses and induce type I interferons.
