Pattern recognition receptors (PRR) are proteins that scan the host tissues for nonself-entities such as invading microbes or altered/damaged host-tissue. PRRs recognize molecular patterns present on the surface of microbes or damaged/altered tissue. The recognition induces a series of protective immune processes.


Pattern Recognition Receptors

Pattern recognition receptor (PRR) is a superfamily of proteins that scans the host tissues for nonself-entities such as microbes or damaged tissue. The distinction between self and nonself is based on specific molecular patterns present on the surface or secreted by the foreign entities. In case of microbial infection, these molecular patterns are lipopolysaccharides (LPS), peptidoglycans, etc. Collectively, the microbial molecular patterns are referred to as microbe-associated molecular patterns or MAMPs. In cases of damaged host tissue,...
