Human Plasma Platelet-activating Factor Acetylhydrolase
Human plasma platelet-activating factor (PAF) acetylhydrolase hydrolyzes the sn-2 acetyl residue of PAF, but not phospholipids with long chain sn-2 residues. It is associated with low density lipoprotein (LDL) particles, and is the LDL-associated phospholipase A, activity that specifically degrades oxidatively damaged phospholipids (Stremler, K. E., Stafforini, D. M., Prescott, S. M., Zimmerman...
متن کاملHuman plasma platelet-activating factor acetylhydrolase.
Platelet-activating factor (PAF, 1-0-alkyl-2-acetylsn-glycero-3-phosphocholine) is a biologically active phospholipid synthesized by a variety of cell types upon appropriate stimulation. PAF is a potent hypotensive factor and it activates platelets and inflammatory cells at concentrations as low as 10”’ M. Removal of the acetyl moiety at the sn-2 position abolishes the biological activity and t...
متن کاملHuman plasma platelet-activating factor acetylhydrolase. Association with lipoprotein particles and role in the degradation of platelet-activating factor.
Platelet-activating factor (PAF) is a bioactive phospholipid (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine) synthesized by a variety of mammalian cell types. PAF induces hypotension, and activates neutrophils and platelets, among other actions. Removal of the acetyl moiety abolishes biological activity, so this reaction may regulate the concentration of PAF and its physiological effects. We h...
متن کاملDifferential expression of platelet-activating factor acetylhydrolase in lung macrophages.
Platelet-activating factor (PAF) acetylhydrolase plays a crucial role inactivating the potent inflammatory mediator, PAF. PAF is implicated in the initiation and propagation of acute lung injury. Although PAF acetylhydrolase is a constitutively active plasma protein, increased PAF production during inflammatory events may necessitate an increase in PAF acetylhydrolase activity in the local envi...
متن کاملSerum platelet-activating factor acetylhydrolase activity in dengue.
INTRODUCTION Severe dengue infection is characterized by enhanced vascular permeability produced by cytokines and biochemical mediators. One of these mediators is the platelet-activating factor. Degradation of platelet-activating factor is accomplished by its specific acetylhydrolase. Down or up regulation of this enzyme has been linked to several diseases. However, the role of this enzyme in d...
