摘要: 中性粒细胞胞外诱捕网(neutrophil extracellular trap,NET)是中性粒细胞接受外界刺激后释放至胞外的由核DNA和/或线粒体DNA及多种蛋白组成的网状结构,其在靶向清除病原体、炎症、自身免疫等方面发挥重要作用。近年来研究表明NET参与了糖尿病视网膜病变(diabetic retinopathy,DR)的发生发展。2型糖尿病的高血糖和低度炎性环境能够在视网膜诱发NET。DR本身也能够增加视网膜血管内中性粒细胞的黏附并诱发NET,而NET能反作用于DR炎症。此外,NET能诱导视网膜病理性新生血管消退。对NET的深入研究为DR发病机制及其防治提供了新思路。(国际眼科纵览,2023, 47:350-353)

Abstract: Neutrophil extracellular traps(NETs) are network structures composed of nuclear DNA and/or mitochondrial DNA and various proteins released by neutrophils after receiving external stimulation. NETs play an important role in clearing pathogens, inflammation, autoimmunity, etc. Recent years, increasing evidence suggests that NETs are involved in the development of diabetic retinopathy (DR). The hyperglycemic and low-grade inflammatory environment in T2DM can induce NETs in the retina. DR itself also can increase the adhesion of neutrophils in retinal vessels and induce NETs. In addition, some studies have demonstrated that NETs can induce the regression of retinal pathological neovascularization. The study of NETs provides new strategies and directions for the prevention and research of DR. (Int Rev Ophthalmol, 2023, 47: 350-353)
