Circulating biologically active oxidized phospholipids show on-going and increased oxidative stress in older male mice

Redox Biology, 2013
Background: The biologically active phospholipids Platelet-activating Factor (PAF) and oxidatively truncated phospholipids from chemical oxidation are increased in the circulation of rats subject to the oxidant stress of chronic ethanol ingestion ...

Modulation by flavonoids of PAF and related phospholipids in endothelial cells during oxidative stress

Journal of Lipid Research, 2003
PAF-dependent transacetylase (TA) modifies the functions of platelet-activating factor (PAF), a potent inflammatory lipid, either by transferring the acetyl group from PAF to lysophospholipids (TAL activity), or to sphingosine (TAS activity) or by ...

Enzymatic activity of the human 1-acylglycerol-3-phosphate-O-acyltransferase isoform 11: upregulated in breast and cervical cancers[S]

Journal of Lipid Research, 2010
The conversion of lysophosphatidic acid (LPA) to phosphatidic acid is carried out by the microsomal enzymes 1-acylglycerol-3-phosphate-O-acyltransferases (AGPATs).

Platelet-activating factor acetylhydrolase

Prostaglandins & Other Lipid Mediators, 2002
Platelet-activating factor (PAF) is one of the most potent lipid mediators and is involved in a variety of physiological events. The acetyl group at the sn-2 position of its glycerol backbone is required for its biological activity, and deacetylation of PAF induces loss of activity. The deacetylation reaction is catalyzed by PAF-acetylhydrolase (PAF-AH)

Ginkgolide B inhibits the neurotoxicity of prions or amyloid-β_1-42

Journal of Neuroinflammation, 2004
Background Neuronal loss in Alzheimer's or prion diseases is preceded by the accumulation of fibrillar aggregates of toxic proteins (amyloid-β1-42 or the prion protein).

The emerging roles of PAF acetylhydrolase

Journal of Lipid Research, 2009
Platelet-activating factor (PAF), a phospholipid autacoid with potent effects throughout the innate immune system, is selectively degraded by two small families of PAF acetylhydrolases (PAF-AHs).

Macrophage Derived Platelet Activating Factor Implicated in the Resolution Phase of Gouty Inflammation

International Journal of Inflammation, 2014
Human blood derived in vitro differentiated monocytes or macrophages are a population of cells which have been investigated over the years to determine the role these cells play in the resolution phase of gout.

Semi-synthetic preparation of 1-O-[1'-14C]hexadecyl-2-acetyl-sn-glycero-3-phosphocholine (platelet activating factor) using plant cell cultures.

Journal of Lipid Research, 1985
Incubation of photomixotrophic cell suspension cultures of rape (Brassica napus) and heterotrophic cell suspension cultures of soya (Glycine max) with 1-O-[1'-14C]hexadecyl-sn-glycerol or rac-1-O-[1'-14C]hexadecylglycerol leads in high yield (up to 78 ...

Effect of platelet activating factor antagonist treatment on gentamicin nephrotoxicity

Mediators of Inflammation, 1992
To assess whether PAF could be involved in the gentamicin-induced nephrotoxicity, we have studied the effect of PAF antagonist BN-52021 on renal function in rats after gentamicin (GENTA) treatment.
