The interaction of blood platelets with collagen is generally considered to be of primary importance in the arrest of bleeding and to have a role in the pathogenesis of thrombosis and atherosclerosis. Following damage to the vascular endothelium, circulating platelets come into contact with exposed collagen fibrils in the subendothelium and spread along it; this is followed by the secretion of several biologically active substances and by aggregation of platelets. The glycoproteins of the platelet plasma membrane have an important role in the mechanisms underlying these processes. So far, two specific defects of platelet function in patients with a bleeding disorder are known to be associated with a glycoprotein defect and the study of these patients has contributed significantly to present concepts of platelet function. The glycoprotein (GP) IIB-III complex, absent or deleted in the aggregation-defective Glanzmann's thrombasthenia, has been identified as the platelet fibrinogen receptor. GPIb, which is absent in the adhesion-defective Bernard-Soulier syndrome, has been identified as the von Willebrand factor receptor on platelets. We now report a defect of the platelet plasma membrane glycoprotein composition in a patient whose platelets are totally unresponsive to collagen.
