Intracellular PAF catabolism by PAF acetylhydrolase counteracts continual PAF synthesis.
Stimulated inflammatory cells synthesize platelet-activating factor (PAF), but lysates of these cells show little enhancement in PAF synthase activity. We show that human neutrophils contain intracellular plasma PAF acetylhydrolase (PLA2G7), an enzyme normally secreted by monocytes. The esterase inhibitors methyl arachidonoylfluorophosphonate (MAFP), its linoleoyl homolog, and Pefabloc inhibit ...
متن کاملPlatelet-activating factor (PAF)-induced rhinitis and involvement of PAF in allergic rhinitis in guinea pigs.
The effects of inhaled PAF on the guinea pig nasal mucosa were investigated. Intranasal pressure (INP) was recorded as an index of intranasal resistance. To access the capillary premeability of nasal mucosa, exudation of Evans blue into the nasal lavage fluid was determined. Inhalations of histamine and PAF markedly and significantly increased INP and dye exudation into the nasal cavities. The ...
متن کاملIncreased hepatic platelet activating factor (PAF) and PAF receptors in carbon tetrachloride induced liver cirrhosis.
BACKGROUND AND AIMS The liver is a major site for the synthesis and actions of platelet activating factor (PAF), a potent hepatic vasoconstrictor and systemic vasodilator. As PAF is implicated in portal hypertension and hyperdynamic circulation associated with liver cirrhosis, we characterised changes in the hepatic PAF system in experimental cirrhosis. METHODS In rats made cirrhotic by carbo...
متن کاملIn vitro inhibitory effect of SR 27417, a potent platelet-activating factor (PAF) receptor antagonist, on the PAF-induced bovine platelet aggregation.
The in vitro inhibitory effect of SR 27417, an antagonist of the platelet-activating factor (PAF) receptor, on PAF-induced platelet aggregation was studied in blood collected from seven healthy Friesien calves. Inhibitory effects of SR 27417 were determined at thirteen different concentrations (0.1-400 nM) by using the dose-response curves of PAF on calf platelet aggregation. In the presence of...
متن کاملMonoclonal anti-idiotypic antibodies to platelet activating factor (PAF) and their interaction with PAF receptors.
Monoclonal anti-idiotypic antibodies (3C3F3E4 and 10D3F8H7) that interact with platelet activating factor (PAF) receptors were generated using an auto-anti-idiotypic approach by immunizing mice with an aldehydic analog of PAF coupled to bovine thyroglobulin. The resulting hybridomas were screened for anti-idiotypic antibody (anti-anti-PAF) with F(ab')2 fragments of affinity-purified polyclonal ...
