Tissue Factor, Blood Coagulation, and Beyond: An Overview
Emerging evidence shows a broad spectrum of biological functions of tissue factor (TF). TF classical role in initiating the extrinsic blood coagulation and its direct thrombotic action in close relation to cardiovascular risks have long been established. TF overexpression/hypercoagulability often observed in many clinical conditions certainly expands its role in proinflammation, diabetes, obesi...
متن کاملThe tissue factor requirement in blood coagulation.
Formation of thrombin is triggered when membrane-localized tissue factor (TF) is exposed to blood. In closed models of this process, thrombin formation displays an initiation phase (low rates of thrombin production cause platelet activation and fibrinogen clotting), a propagation phase (>95% of thrombin production occurs), and a termination phase (prothrombin activation ceases and free thrombin...
متن کاملTissue factor-dependent autoactivation of human blood coagulation factor VII.
We recently showed that single-chain zymogen factor VII is converted to two-chain factor VIIa in an autocatalytic manner following complex formation with either cell-surface or solution-phase relipidated tissue factor apoprotein (Nakagaki, T., Foster, D. C., Berkner, K. L., and Kisiel, W. (1991) Biochemistry 30, 10819-10824). We have now performed a detailed kinetic analysis of the autoactivati...
متن کاملTissue factor: beyond coagulation in the cardiovascular system.
TF (tissue factor) is the main trigger of the coagulation cascade; by binding Factor VIIa it activates Factor IX and Factor X, thereby resulting in fibrin formation. Various stimuli, such as cytokines, growth factors and biogenic amines, induce TF expression and activity in vascular cells. Downstream targets of these mediators include diverse signalling molecules such as MAPKs (mitogen-activate...
متن کاملVitamin K: the effect on health beyond coagulation – an overview
Vitamin K is essential for the synthesis of proteins belonging to the Gla-protein family. To the members of this family belong four blood coagulation factors, which all are exclusively formed in the liver. The importance of vitamin K for hemostasis is demonstrated from the fact that vitamin K-deficiency is an acute, life-threatening condition due to excessive bleeding. Other members of the Gla-...
