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 کاملPlatelet-activating factor acetylhydrolase prevents myocardial ischemia-reperfusion injury.
BACKGROUND Platelet-activating factor (PAF) is one of the most potent biological mediators of tissue injury. PAF acetylhydrolase (PAF-AH) is a recently isolated naturally occurring enzyme that hydrolyzes PAF and renders it inactive. We hypothesize that inhibition of PAF with PAF-AH will reduce myocardial ischemia-reperfusion (I/R) injury in vivo. METHODS AND RESULTS The coronary ligation mode...
متن کاملPlatelet-activating factor acetylhydrolase and premature ovarian failure.
Premature ovarian failure (POF) appears to be a complex disease entity with several underlying etiopathogenic contributions including the possibility of multiple distinctly different autoimmune mechanisms, in which inflammatory autoimmunity targeted to ovarian-specific germline antigens (e.g., zona pellucida proteins or Mater) or differentiation/regulatory factors (e.g. inhibin-alpha) were rega...
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...
