| Outline of Final Research Achievements |
Thrombomodulin (TM) is a vascular endothelial cell receptor that functions as a cofactor for activated protein C (APC). From the viewpoint of coagulation control using TM in transplantation, two strategy including (i) administration of recombinant soluble thrombomodulin (S-hTM), which has been approved for the treatment of sepsis-induced DIC, and (ii) upregulation of membrane-bound TM (MB-hTM) expression in endothelial cells would be proposed. As a result, S-hTM had more potent capacity of APC production and inhibitory effect on thrombin generation than MB-hTM. In contrast, MB-hTM suppressed the expression of inflammatory factor in endothelial cells. It was speculated that S-hTM treatment would be of assistance during high-risk periods for excessive thrombin formation (e.g., ischemia reperfusion injury or severe infection/rejection). Considering the properties of MB-hTM exhibiting anti-inflammatory function, might be required to long-term stabilization of graft endothelial cells.
