Neutrophil extracellular traps (NETs) are net-like structure composed of DNA and nuclear proteins, which are produced by activated neutrophils under the circumstances of a variety of pathogens or drugs. As part of defensive mechanism, NETs have been proved to restrict the spread of pathogens and release of antimicrobial molecules. NETs can not only strengthen the adhesion between neutrophils and platelets, promote platelet mediated procoagulant reaction, but also lead to endothelial cell damage and coagulopathy in sepsis. In addition, NETs also plays an important role in pathophysiological processes of venous thrombosis. Therefore, NETs may become the biomarkers of evaluating coagulation dysfunction and potential therapy target in sepsis.
中性粒细胞胞外陷阱(NETs)是由DNA和核蛋白组成的网状结构,由活化的中性粒细胞在多种病原体或药物作用下产生。作为防御机制的一部分,NETs已被证明可限制病原体的传播并释放抗菌分子。NETs不仅可增强中性粒细胞与血小板之间的黏附,促进血小板介导的促凝反应,还可导致脓毒症中的内皮细胞损伤和凝血病。此外,NETs在静脉血栓形成的病理生理过程中也起重要作用。因此,NETs可能成为评估脓毒症凝血功能障碍的生物标志物和潜在治疗靶点。
