FPRL1 or FPR2/ALX as commonly called is a seven transmembrane protein like all GPCRs. This receptor was originally cloned by screening a HL60 neutrophil cDNA library with a FPR1 cDNA probe. FPR2/ALX shares 69% identity with FPR1 and despite its high homology, it displays relatively low affinity for fmlf, the most potent N-formyl peptide released by bacteria3.FPR2/ALX has a similar tissue distribution to that of FPR1.While N-formyl peptides were the first peptides found to activate these receptors, the ligand diversity for FPR has proven to be quite broad and demonstrates to be both pro- and anti-inflammatory. They include peptidic ligands originating from bacterial and viral sources (including HIV), endogenous ligands such as chemokines and annexins, short peptides associated with inflammation and infection. Interestingly, b-amyloid peptide, a known marker for Alzheimer’s disease activates FPR2/ALX thereby directly linking these receptors to the neurodegenerative disease. Lipoxin A4 (LXA4) is the first identified endogenous ligand for FPR2/ALX and is an eicosanoid with potent anti-inflammatory characteristics.
