Formylated peptides
WebIn humans, N-formylated hexapeptides such as ND4, ND6, and COI are agonists of formyl peptide receptor-1 and induce chemotactic cellular responses involved in the modulation of the immune response 22 Krysko D.V. WebThe formyl peptide receptors (FPRs) are a group of G protein-coupled chemoattractant receptors that play important roles in host defense and inflammation [1,2].They are so named because their cognate agonists are peptides bearing formylated methionine (fMet), such as those derived from bacterial and mitochondrial proteins [3,4].The present review …
