Pattern recognition receptors (PRRs) play a crucial role in the proper function of the innate immune system. PRRs are germline-encoded host sensors, which detect molecules typical for the pathogens. They are proteins expressed, mainly, by cells of the innate immune system, such as dendritic cells, macrophages, monocytes, neutrophils and epithelial cells, to identify two classes of molecules: pathogen-associated molecular patterns (PAMPs), which are associated with microbial WebNov 20, 2024 · 2.1.1. Pattern Recognition Receptor-Mediated Cytokine and Chemokine Expression in Keratinocytes. As the first line of defense, keratinocytes can sense specific small molecular motifs present on bacteria and other microorganisms, which are referred to as pathogen-associated molecular patterns (PAMPs) [].PAMPs, such as bacterial …
