Activated Protein C exerts an antithrombotic effect by inhibiting Factors Va and VIIIa. In vitro data indicate that Activated Protein C has indirect profibrinolytic activity through its ability to inhibit plasminogen activator inhibitor-1 (PAI-1) and limiting generation of activated thrombin-activatable-fibrinolysis-inhibitor. Additionally, in vitro data indicate that Activated Protein C may exert an anti-inflammatory effect by inhibiting human tumor necrosis factor production by monocytes, by blocking leukocyte adhesion to selectins, and by limiting the thrombin-induced inflammatory responses within the microvascular endothelium Synonyms: Coagulation factor V, Activated protein C cofactor, FVL, PCCF, factor V, APC.
