In vivo and in vitro inhibition of platelet aggregation by SV-IV, a major protein secreted from the rat seminal vesicle epithelium

Abstract

In summary, the present study documents that platelet aggregation triggered by thrombin, ADP, collagen and PAF both in vivo and in vitro, was prevented by SV-IV in a dose-dependent manner. Only platelet aggregation by AA was not affected by the protein, thus suggesting a possible involvement of PLA2 inhibition in the molecular mechanism at the basis of SV-IV anti-thrombotic effect.
