The haemostatic role of tissue factor pathway inhibitor.
Review published in Arteriosclerosis, thrombosis, and vascular biology (2007)
Abstract
Under normal conditions the blood circulates freely within the confines of the vascular system, carrying oxygen, nutrients, and hormonal information around the body and removing metabolic waste. If blood gains access to extravascular sites, or the vasculature becomes pathologically challenged, hemostasis may be activated. This process is finely regulated by positive and negative feedback loops that modulate fibrin clot formation. Blood coagulation revolves around the activation and assembly of the components of the prothrombinase complex, which converts the inactive zymogen, prothrombin, into its active form, thrombin. This serine protease catalyzes the conversion of fibrinogen to fibrin, the structural scaffold that stabilizes platelet aggregates at sites of vascular injury. The extent of the hemostatic response is controlled by the action of inhibitory pathways, which ensure that thrombin activity and the spread of the hemostatic plug is limited to the site of vessel damage. This review article focuses on the major physiological regulator of tissue factor-induced coagulation, tissue factor pathway inhibitor, its expression, anticoagulant function, and its role in normal hemostasis.

Por qué esto importa para la hirudoterapia
Este artículo de revisión examina el papel fisiológico del inhibidor de la vía del factor tisular (TFPI) en la regulación de la coagulación inducida por el factor tisular y en el mantenimiento del equilibrio hemostático. Describe cómo el TFPI modula la generación de trombina y limita la propagación del coágulo a los sitios de lesión vascular. Para ASH, el artículo aporta antecedentes sobre las vías anticoagulantes endógenas que se corresponden con algunos mecanismos de los anticoagulantes derivados de la sanguijuela, como la hirudina, ofreciendo contexto para comprender la cascada de coagulación más amplia con la que interactúan los componentes del secretoma de la sanguijuela. ADVERTENCIA: Esta revisión no contiene ninguna discusión directa sobre sanguijuelas, hirudina, hirudoterapia ni ningún compuesto derivado de la sanguijuela; su relevancia es estrictamente indirecta como contexto general de biología de la coagulación.
