Description

Biochem/physiol Actions

Ristocetin activates platelets. Ristocetin-induced platelet agglutination (RIPA) is decreased in patients undergoing chronic hemodialysis. Together with increased plasma glycocalicin levels (a product of enzymatic cleavage of GPIb), RIPA may contribute to diminished platelet adhesion to vascular subendothelium and increased bleeding associated with uremia. Addition of ristocetin and vWf caused specific agglutination of rGPIbα-liposomes suporting the potential use of rGPIbα-liposomes to enhance platelet function in vivo and support hemostasis in thrombocytopenic individuals.
