Answer

Abrogation of the TF/factor VII(a) pathway by monoclonal antibodies specifically directed against TF or factor VIIa activity completely inhibited of thrombin generation in endotoxin-challenged chimpanzees and prevented the occurrence of DIC and mortality in baboons that were infused with Escherichia coli. Indeed, in most DIC patients, TF antigen is detectable in plasma. Hence, activation of coagulation in DIC is primarily TF-driven; the intrinsic pathway of coagulation appears not to play an important role.
