Role of prostaglandin biochemical pathway in platelet-vessel wall interaction and local thrombosis.
Prostaglandins play an important role in the platelet-vessel wall interaction. The inhibition of PGI2 synthetase results in an increase of platelet thrombosis induced by adenosine diphosphate. Addition of exogenous arachidonic acid further increases the phenomenon. The ratio of cyclic endoperoxides (PGG2 and PGH2) to prostacyclin (PGI2) could well be the determining trigger in platelet-vessel wall interaction and local thrombosis.
