Cytoplasmic nucleic acid sensors
WebFeb 22, 2016 · Nucleic acid sensing is a key element of antimicrobial immunity (Wu & Chen, 2014 ). Diverse nucleic acid sensors act as pattern recognition receptors (PRRs), initiating innate immune responses necessary to protect against pathogens containing a diverse range of nucleic acid species (Wu & Chen, 2014 ). WebThe best studied cytoplasmic nucleic acid sensors are RNA sensors. These include PKR and members of the family of retinoic acid-inducible gene I (RIG-I)-like helicases (RLHs), which detect single- and double-stranded viral RNA.
