Blood coagulation factor VIII (FVIII) is a crucial protein cofactor within the blood coagulation cascade and facilitates the proteolytic activation of factor X by activated factor IX. During coagulation FVIII is activated and binds, via its C1 and C2 domains, to activated platelet membranes coordinated by interactions with exposed phosphatidylserine on the membrane surface. A deficiency of functional FVIII within a patient's bloodstream leads to the blood disorder hemophilia A, which results in prolonged bleeding episodes. Current treatment for hemophilia A relies on FVIII replacement therapy via the injection of exogenous FVIII. The main complication which arises from FVIII replacement …
