Understanding the Function of Pattern Recognition Receptors (PRRs) in the Immune Response

prr pamps:Which is found on leukocytes? Which is found on pathogens?

PRR’s are found on leukocytes, whereas PAMP’s are found on pathogens.

PRR (Pattern Recognition Receptors) are found on both leukocytes (a type of white blood cells) and pathogens.

Leukocytes express various types of PRRs, including Toll-like receptors (TLRs), Nod-like receptors (NLRs), and RIG-I-like receptors (RLRs). These PRRs help leukocytes recognize and respond to pathogenic invasion by detecting patterns or signatures that are unique to the pathogen.

Pathogens also possess PRRs, which are known as Pathogen-associated molecular patterns (PAMPs). PAMPs are conserved molecular structures found on the surface of pathogens, such as bacteria, viruses, fungi, and parasites. They are recognized by the PRRs of the host cells, such as leukocytes, activating the host immune response against the pathogen.
