1-Alkyl-2-acetyl-sn-glycero-3-phosphocholine (alkylacetyl-GPC; platelet-activating factor; PAF) is actively taken up and metabolized by rat alveolar macrophages maintained in culture. The major metabolic products are lyso-PAF (alkyllyso-GPC) and alkylacyl-GPC. Lyso-PAF accumulates primarily in the media, whereas alkylacyl-GPC is predominantly associated with cellular

Suspensions of neonatal rat myocytes were used to investigate the metabolism of [3H]PAF (1-alkyl-2-acetyl-(sn-glycero-3-phosphocholine) (GPC] and [3H]alkyllyso-GPC. [3H]Alkylacyl-GPC consisting of molecular species with four or more double bonds (87%) was the major metabolite formed when either [3H]PAF (4 x 10(-6)

Platelet-activating factor (PAF [1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine]) is a phospholipid mediator released from activated macrophages, mast cells, and basophils that promotes pathophysiologic inflammation. Eosinophil responses to PAF are complex and incompletely elucidated. We show in this article that PAF and its 2-deacetylated metabolite
