摘要

目的:从炎症角度探讨小胶质细胞在糖尿病视网膜病变(DR)发病机制中的作用。方法:检索多个数据库进行研究。收集、总结、总结相关文章。结果:已经进行了大量的研究来确定炎症生物标志物,以有效地检测DR;然而,结果却不一致。小胶质细胞,视网膜组织的常驻免疫细胞,被认为在视网膜长期高血糖诱导的神经炎症过程中发挥潜在作用。高血糖引起的细胞外三磷酸腺苷(eATP)的过度释放可能过度刺激P2X7R受体,从而激活NLRP3炎性体,导致慢性进行性炎症。结论:小胶质细胞的激活和极化可诱导间性炎症,促进通透性和新生血管的增加,从而导致增殖性糖尿病视网膜病变。了解这一机制对于确定早期DR检测的潜在生物标志物和开发辅助治疗来控制疾病进展至关重要。

Retinal Microglia: Revealing New Opportunities for Identifying Early Biomarkers of Diabetic Retinopathy.

Purpose: To explore the role of microglia in the pathomechanism of diabetic retinopathy (DR) from an inflammatory perspective.Methods: The study was conducted by searching several databases. Relevant articles were collected, summarized, and concluded.

Results: Numerous studies have been conducted to identify inflammatory biomarkers for effective detection of DR; however, the results have been inconsistent. Microglia, the resident immune cells of the retinal tissue, are believed to play a potential role in the neuroinflammatory process induced by prolonged hyperglycemia in the retina. The excessive release of extracellular adenosine triphosphate (eATP) due to hyperglycemia may overstimulate P2X7R receptors, thereby activating the NLRP3 inflammasome, and leading to chronic progressive inflammation.

Conclusion: Microglial activation and polarization may induce meta-inflammation, contributing to increased permeability and neovascularization, which in turn lead to proliferative diabetic retinopathy. Understanding this mechanism is essential for identifying potential biomarkers for early DR detection and developing adjunctive therapies to control disease progression.
