Outline of Final Research Achievements

Sepsis is a severe pathological condition with multiple organ failure and has been a leading cause of death worldwide. Although the efforts has been continued for developing specific drugs for the treatment of sepsis for decades, none of them was successful. In the present study, we tried to clarify the mechanism of septic pathophysiological cascade triggered by the decrease in plasma histidine-rich glycoprotein (HRG) in mice and an action mechanism of supplemental treatment with purified HRG. We also suggested the involvement of red blood cells in immunothrombosis in addition to well-known participants, neutrophils and vascular endothelial cells, based on the in vitro experimental results. It was demonstrated that supplemental treatment with HRG was beneficial for septic ARDS in mice.
