Histidine-rich glycoprotein (HRG) is a 75 kDa plasma glycoprotein synthesized in liver mainly, which exists at approximately 60-100 μg/ml in human plasma. HRG is known to bind to several ligands and cells, leading to exert coagulation, fibrinolysis, immune and inflammation regulatory activity in septic condition. Thus, decreased plasma HRG level induces the dysregulations of coagulation, fibrinolysis and immune system, resulting in disseminated intravascular coagulation and multiple organ failure. This article focuses on the physiological activity of HRG and the potential of HRG as the biomarker and therapeutic drug for sepsis.
富含组氨酸的糖蛋白(HRG)是一种主要在肝脏中合成的75 kDa血浆糖蛋白,在人血浆中的存在浓度约为60 - 100 μg/ml。已知HRG可与多种配体和细胞结合,在脓毒症状态下发挥凝血、纤维蛋白溶解、免疫和炎症调节活性。因此,血浆HRG水平降低会导致凝血、纤维蛋白溶解和免疫系统失调,从而引发弥散性血管内凝血和多器官功能衰竭。本文重点关注HRG的生理活性以及HRG作为脓毒症生物标志物和治疗药物的潜力。
