FPR1 is a member of chemoattractant/chemokine GPCRs expressed mainly on leukocytes, neutrophils and monocytes. FPR1 is a seven transmembrane pertussis toxin-sensitive GPCR and binds to formylated peptides generated by bacteria resulting in leukocyte trafficking to the site of inflammation. Ligand binding to FPR results in activation of multiple effectors including phospholipase C leading to calcium mobilization and PKC activation. Other implications of FPR signaling include polarization of actin cytoskeletion, activation of various integrins, increased cell migration, phagocytosis, degranulation and release of reactive oxygen intermediates. Formyl peptide receptor 1, a Chemoattractant Receptor, mediates chemotaxis, degranulation, and superoxide production, as part of the inflammatory response. Bacterial N-formylmethionyl peptides and Annexin A1, specific ligands for FPR1, attract polymorphonuclear neutrophils to sites of infection. FPR receptors promote the phosphorylation and downregulation of CCR5, which has been shown to inhibit HIV infection. Therefore, ligands for an FPR receptor may be able to inhibit HIV infection.
