产品描述:
N-Formyl-Met-Leu-Phe (fMLF) is a synthetic peptide that acts as an agonist at formyl peptide receptors (FPRs; Ki = 0.8 pM), which are mainly localized on polymorphonuclear and mononuclear phagocytes.{34517} Activation of FPRs by fMLF leads to cellular activation, which is characterized by cellular polarization, chemotaxis, and release of proteolytic enzymes.{34518} fMLF induces contractions in isolated guinea pig jejunum (EC50 = 11 nM), proximal colon (EC50 = 3.5 nM), and distal colon (EC50 = 2.2 nM).{34516} In vitro, fMLF induces neurotransmitter release from enteric motor neurons.
