Background: The lipoxin A4 receptor ALX is also known as formyl peptide receptor-like 1 (FPRL1) or formyl peptide receptor 2 (FPR2). It shares 69% amino acid identity with FPR but displays low affinity for bacterial peptide N-formyl-methionyl-leucyl-phenylalanine (fMLF). ALX is highly expressed on neutrophils and monocytes and mediates cell chemotaxis. By interacting with a variety of exogenous and host-derived agonists, ALX may have important implications in the pathogenesis of human diseases such as HIV, Alzheimer’s disease (AD), amyloidosis and prion diseases.
