Pattern Recognition Receptors (PRRs, [110]) (nomenclature as agreed by NC-IUPHAR sub-committee on Receptors, [20]) participate in the innate immune response to microbial agents, stimulation of which leads activation intracellular enzymes and regulation gene transcription. PRRs express multiple leucine-rich regions bind a range microbially-derived ligands, termed PAMPs or pathogen-associated mol...
