tromboplastinový
Tromboplastinový refers to a substance involved in blood clotting. It is not a single entity but rather a term that can describe a complex of proteins and other factors. In the context of coagulation, tromboplastin is often associated with tissue factor, a protein that plays a crucial role in initiating the extrinsic pathway of the coagulation cascade. When tissue factor is exposed to blood following injury, it binds to activated factor VII, forming an enzymatic complex that triggers the production of thrombin, a key enzyme in clot formation.
Historically, the term "tromboplastin" was used more broadly to refer to substances derived from damaged tissues
