Abstract:
We have been investigating the mechanism of blood coagulation and anticoagulation related to pathogenesis and the regulation of thrombosis and bleeding disorders. Since our focus is basically internal medicine and hematology, the contribution to this field is clinically based and aimed to help patients and maintain public health. In this review some of our achievements associated with the activation and regulation of blood coagulation are introduced, mainly based on our research with post-graduate medical technologists. The main topics are the structural and functional relationship of thrombomodulin (TM), the regulation of tissue factor (TF) and TM expression, TM gene therapy, activation of the extrinsic coagulation system due to increased TF-bearing leukocytes during and after cardiac surgery, endoplasmic reticulum-associated degradation of protein C and plasmin inhibitor mutants leading to protein deficiency, activation of blood coagulation with exposure of cellular or viral RNA, and the detection of novel bioactive peptides salusin-alpha and -beta.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
