| Outline of Final Research Achievements |
Extracellular histones stimulated endothelial cells to release von Willebrand factor (VWF). This resulted in massive thrombosis in glomeruli of histone-injected rats. Recombinant thrombomodulin bound to histones and inhibited histone-induced VWF-rich thrombus formation in rats. These findings suggest a novel role of extracellular histones in the pathogenesis of lethal coagulopathy, including thrombotic microangiopathy (TMA) and disseminated intravascular coagulation (DIC).
