The potential impacts of formyl peptide receptor 1 in inflammatory diseases
*Author to whom correspondence should be addressed.
Neutrophils play a critical role in acute and chronic inflammatory diseases. N-formyl peptides, which originate from bacterial peptides or mitochondrial proteins bind with a high binding affinity to formyl peptide receptor 1 (FPR1). N-formyl peptide-FPR1 is involved in the pathogenesis of sterile and infectious inflammatory processes and causes phagocytosis of pathogens or injured cells by neutrophils. Excessive activation of neutrophils by binding of N-formyl peptides is associated with tissue injury requiring drugs that block FPR1-dependent signaling. Here, we review the roles of FPR1 as a critical regulator of inflammatory processes and its involvement in pathological conditions.
