Rw. Farndale et al., THE INHIBITION OF ADENYLATE-CYCLASE IN EQUINE PLATELETS BY COLLAGEN AND BY PLATELET-ACTIVATING-FACTOR, Platelets, 7(1-2), 1996, pp. 43-46
Equine platelet aggregation was stimulated by collagen fibres or plate
let-activating factor. The action of both ligands was blocked by forsk
olin or prostaglandin E(1), agents which are known to activate adenyla
te cyclase. Equine platelet membranes were found to contain adenylate
cyclase activity which was inhibited in dose-dependent fashion by both
collagen and platelet-activating factor. Platelet-activating factor-i
nduced inhibition was antagonised by WEB2086.
