Amino Acid Sequence

NFor-Met-Leu-Phe

Description générale

N-Formyl-Met-Leu-Phe is a chemotactic peptide, which functions on polymorphonuclear leukocytes (PMN), neutrophils etc.

Research area: Cell signaling

Application

N-Formyl-Met-Leu-Phe has been used for:

  • creating gradients in Zigmond chamber chemotaxis assay performed on neutrophils
  • neutrophil chemotaxis assay
  • determination of the involvement of MAPK-activating protein kinase-2 (MAPKAPK-2) and/or p38, in the signaling pathway of human polymorphonuclear leukocytes (PMNs) stimulated by N-Formyl-Met-Leu-Phe.

Actions biochimiques/physiologiques

N-Formyl-Met-Leu-Phe induced chemotaxis in phosphoinositide 3-kinase γ (PI3K)γ-/- neutrophils, and promotes adhesion, polymerization of F-actin, Fcγ receptor-mediated phagocytosis and intracellular Ca2+ release. It acts as an inflammatory agent and activates polymorphonuclear leukocytes (PMNs) without the formation of 5-hydroxyicosatetraenoic acid (5-HETE) and leukotriene B4 (LTB4). Its effects on neutrophils and the inhibition of adenylate cyclase are inhibited by pertussis toxin.
Potent chemotactic peptide. Induces a metabolic burst in macrophages accompanied by an increase in respiratory rate, secretion of lysosomal enzymes, and production of superoxide anion.
Potent inducer of leucocyte chemotaxis and macrophage activator. Receptors that bind formylpeptides are found on phagocytic neutrophils and have recently been identified on cells of the intestinal mucosa.

Pertussis toxin inhibits the N-formyl-Met-Leu-Phe (fMet-Leu-Phe) mediated human neutrophil functions of enzyme release, superoxide generation, aggregation, and chemotaxis. As pertussis toxin modifies the GTP binding receptor-regulatory protein "Ni," the association of the fMet-Leu-Phe receptor with such a protein was further

In recent years, the number of new antimicrobial drugs launched on the market has decreased considerably even though there has been an increase in the number of resistant microbial strains. Thus, antimicrobial resistance has become a serious public health problem.

Release of arachidonic acid by the membrane phospholipase and metabolism by the 5-lipoxygenase pathway was examined in human polymorphonuclear leukocytes (PMNs). The 5-lipoxygenase pathway is activated when PMNs are given arachidonic acid in ethanol and there is extensive metabolism to

Activation of polymorphonuclear leukocytes (PMN) by chemotactic peptides initiates a series of functional responses that serve to eliminate pathogens. The intermediate steps that link engagement of the chemoattractant receptor to the microbicidal responses involve protein kinases that have yet to
