Peptidoglycan recognition proteins (PGRPs) are a group of highly conserved pattern recognition receptors with at least one peptidoglycan recognition domain capable of recognizing the peptidoglycan component of the cell wall of bacteria. They are present in insects, mollusks, echinoderms and chordates. The mechanism of action of PGRPs varies between taxa. In insects, PGRPs kill bacteria indirectly by activating one of four unique effector pathways: prophenoloxidase cascade, Toll pathway, IMD pathway, and induction of phagocytosis.[1][2][3][4] In mammals, PGRPs either kill bacteria directly by interacting with their cell wall or outer membrane, or hydrolyze peptidoglycan.[1][2][3][4] They also modulate inflammation and microbiome and interact with host receptors.[1][3]
