Paf mediator
WebPAF does not act as an independent mediator of platelet aggregation; however, it functions in a manner analogous to TxA2 and adenosine di-phosphate (ADP).48 Platelet reactivity mediators stimulate the release of inflamma- tory eicosanoids and tumor necrosis factor (TNF -α) from leukocytes and endothelial cells. WebPAF is an endogenous phospholipid mediator of inflammation that is produced by inflammatory, endothelial, and lamina propria cells.70PAF has a short half-life and is …
