Answer

NO also plays an important role in the maintenance of normal platelet functions through the down-regulation of platelet aggregation and adhesion and the regulation of molecules in the coagulation cascade. Accordingly, the long-term consumption of NO by plasma Hb has been implicated in the formation of clots in PNH patients. [12]
