Formylpeptide receptors

Overview

The formylpeptide receptors respond to exogenous ligands such as the bacterial product fMet-Leu-Phe (fMLP) and endogenous ligands such as lipoxin A₄ (LXA₄), 15-epi-lipoxin A₄, annexin... [read more] I, cathepsin G, amyloid β42, serum amyloid A and spinorphin, derived from β-haemoglobin. FPR1 also serves as a plague receptor for selective destruction of human immune cells by Y. pestis [1]. The FPR1/2 agonists 'compound 17b' and 'compound 43' have shown cardiac protective functions [2,3].
