Many researchers are going to investigate that coagulation factor, like APC and EPCR, binds to leukocyte, leading to immunothrombosis. We have indicated that leukocyte LFA-1 and Mac-1 integrins bind to the serine/threonine-rich domain of thrombomodulin (TM). In fact, integrin-TM interactions might be involved in the dynamic regulation of leukocyte adhesion with endothelial cells, or immunothrombosis. Based on the results, we indicated here how the coagulation factor, TM on endothelial cell, is associated with leukocyte binding. First, we confirmed that the TNF -alpha induced inflammatory response downregulates TM expression on endothelial cells. Moreover we showed that pheripheral blood mononuclear cells (PBMCs) bind to human umbilical vein endothelial cell(HUVEC) dependent upon integrin activation., 2016年度~2017年度科学研究費補助金(若手研究(B))研究成果報告書, 16K20386}, title = {β2インテグリンとトロンボモジュリンの結合が炎症と凝固に与える影響}, year = {2018}, yomi = {カワモト, エイジ} }
