Amino Acid Sequence
NFor-Met-Leu-Phe
General description
N-Formyl-Met-Leu-Phe is a chemotactic peptide, which functions on polymorphonuclear leukocytes (PMN), neutrophils etc.
Research area: Cell signaling
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.
Biochem/physiol Actions
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.

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.

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

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

Associative memory is the main type of learning by which complex organisms endowed with evolved nervous systems respond efficiently to certain environmental stimuli. It has been found in different multicellular species, from cephalopods to humans, but never in individual cells.

Confocal imaging and time-lapsed videomicroscopy were used to study the directionality, motility, rate of cell movement, and morphologies of phosphoinositide 3-kinase gamma (PI3K)gamma(-/-) neutrophils undergoing chemotaxis in Zigmond chambers containing N-formyl-Met-Leu-Phe gradients. Most of the PI3Kgamma(-/-) neutrophils failed to translocate
