一般說明

Factor V, a glycoprotein is usually seen in the alpha granules of platelets and in plasma.
Factor Va is the activated form of factor V and the cofactor of Xa. It is a component of the prothrombinase complex.

生化/生理作用

Factor V is a key component in blood coagulation systems, where deficiencies can inhibit thrombin generation and affect hemostasis. It has been used in studies of coagulopathic bleeding which occurs following injury and is a leading cause of hospital deaths.
Factor Va serves as a receptor and positive effector of factor Xa. Hence it can efficiently help in the conversion of prothrombin to thrombin.

Coagulopathic bleeding is a leading cause of in-hospital death after injury. A recently proposed transfusion strategy calls for early and aggressive frozen plasma transfusion to bleeding trauma patients, thus addressing trauma-associated coagulopathy (TAC) by transfusing clotting factors (CFs). This strategy
