Complement-induced platelet protein alterations.
Polypeptides of high molecular weight are deleted from the sedimentable fraction of platelets subjected, while intact, to complement action. These polypeptides, distinct from the previously described thrombin-sensitive protein of this fraction, also diminish after platelets are exposed to thrombin. They may be of importance in the molecular events underlying complement-triggered changes in platelet function.
