The ether phospholipid platelet-activating factor and certain similar phospholipids, including lysophosphatidylcholine, are known to stimulate both H(+) transport and protein phosphorylation in plant microsomal membranes. In the present work, several polypeptides in highly purified tonoplast membranes from zucchini (Cucurbita pepo L.) showed platelet-activating factor-dependent phosphorylation....
We investigated the effect of a number of platelet activating factor antagonists on cell killing by 1-O-octadecyl-2-O-methyl-sn-glycero-3-phosphoryl choline (ET-18-OCH3). Of six platelet activating factor antagonists tested, four were found to protect WEHI-3B leukemic cells against cell death induced by ET-18-OCH3. Certain other compounds, not platelet activating factor antagonists, had similar...
Systemic sclerosis is characterised by vascular endothelial damage. Platelets adhering to the exposed subendothelium may contribute to the inflammatory changes found in the vessel wall. Increased in vitro platelet aggregability in systemic sclerosis has been reported. In vitro platelet aggregation of platelet rich plasma obtained from patients with systemic sclerosis (CREST (calcinosis, Raynaud...
Platelet-activating factor acetylhydrolase was analyzed in cerebrospinal fluid samples taken from children with a variety of neurological conditions (85 patients; mean age, 3.8 years) to determine it is involved in the defense mechanism against the toxic effect of inflammatory mediators in the central nervous system. A significant increase in cerebrospinal fluid activity was seen in the patient...
PURPOSE To determine the distribution of platelet-activating factor (PAF) receptor in the rat eye. METHODS Platelet-activating factor receptor messenger RNA (mRNA) expression was evaluated with reverse transcription-polymerase chain reaction (RT-PCR) in RNAs from several rat ocular tissues. Distribution of the expression was determined with in situ hybridization in adult rat eye sections and ...
