Platelet-activating factor-mediated synthesis of prostaglandins in rat Kupffer cells.

Synthesis of prostaglandins was stimulated in rat Kupffer cells upon challenge with platelet-activating factor (PAF). PAF-mediated synthesis of prostaglandins was inhibited by the Ca2+ ion chelator (EGTA), the Ca2+ channel antagonist (nifedipine) and U66985, a structural analogue and antagonist of the biological effects of PAF in other cellular systems… CONTINUE READING
