The formyl peptide receptor 2 (FPR2), in particular, plays a crucial role in host defense and inflammation. It is a promiscuous receptor, capable of binding to a diverse range of ligands, including bacterial peptides, endogenous lipids, and even certain neuropeptides. This promiscuity allows FPR2 to integrate signals from various sources, contributing to a nuanced inflammatory response. The human N-formyl peptide receptor (FPR), as a representative of this receptor family, is part of a family of G protein-coupled receptors that respond to chemokines and other signaling molecules.Formylpeptide receptors | G protein-coupled receptors

The activation of these receptors has profound effects on immune cell behavior. For example, engagement of FPR1 by formyl peptides elicits robust innate immune responses, which can, in certain contexts, exacerbate damageFPR1 - N-formyl peptide receptor 1 - Homo sapiens (Human).
