What are pattern recognition receptors?

Pattern recognition receptors (PRRs) are a vital component of the innate immune system, playing a crucial role in detecting and responding to various pathogen-associated molecular patterns (PAMPs). These receptors are expressed on the surface of immune cells and are capable of recognizing specific patterns commonly found on pathogens, such as bacteria, viruses, and fungi. Upon detection of these PAMPs, PRRs trigger a series of signaling pathways that lead to the activation of the immune response, including the production of pro-inflammatory cytokines, chemokines, and antimicrobial peptides. Overall, PRRs play a key role in initiating the immune response against invading pathogens and are essential for host defense against infections.
