Description:  University of New Mexico Assay Overview: Assay Support: NIH 1R03MH076381-01 Assay for Formylpeptide Receptor Family Ligands PI: Bruce S. Edwards, Ph.D. Assay Background and Significance Formyl peptide receptors. The G-protein coupled formylpeptide receptor (FPR) was one of the originating members of the chemoattractant receptor superfamily (Le et al., 2002a; Oppenheim et al., 1991). N-formylated peptides such as fMLF are high affinity FPR ligands that trigger a variety of biologic activities in myeloid cells, including chemokinesis, chemotaxis, cytokine production and superoxide generation (He et al., 2003; Le et al., 2001b; Murphy, 1994; Murphy, 1996; Tiffany et al., 2001). Since such peptides are derived from bacterial or mitochondrial proteins (Carp, 1982; Marasco et al., 1984; Schiffmann et al., 1975a; Schiffmann et al., 1975b), it has been proposed that a primary FPR function is to promote trafficking of phagocytic myeloid cells to sites of infection and tissue damage where
