Pyroptosis, which is put forward after apoptosis, necrosis and autophagy, is a programmed pro-inflammatory cell death mode mainly mediated by inflammasomes. The main signaling pathways include the classic caspase-1-dependent pyroptosis pathway and the non-classical caspase-4, caspase-5 and caspase-11-dependent pyroptosis pathway. Pyroptosis is involved in the normal physiological function and plays an important role in the pathogenesis of many diseases, especially in neurodegenerative diseases such as Alzheimer's disease and glaucoma. Glaucoma, which is mainly related to pathological intraocular pressure elevation, is a kind of eye diseases that threaten and damage the optic nerve and its visual pathway and eventually lead to visual function impairment. With more attention paid to pyroptosis involved in the mechanism of eye diseases and the pathogenesis and treatment of glaucoma, studies have found that pyroptosis is tightly correlated with glaucoma. Pyroptosis of retinal ganglion cells and microglia-mediated pyroptosis possess a significant position in the development of glaucoma. Further understanding of the relationship between pyroptosis and glaucoma might bring a new dawn for glaucoma treatment. The mechanism of pyroptosis may provide a new strategy for the pathogenesis and treatment of glaucoma. .
细胞焦亡是继细胞凋亡、坏死和自噬之后提出的一种程序性促炎细胞死亡模式,主要由炎性小体介导。主要信号通路包括经典的半胱天冬酶-1依赖性细胞焦亡途径和非经典的半胱天冬酶-4、半胱天冬酶-5和半胱天冬酶-11依赖性细胞焦亡途径。细胞焦亡参与正常生理功能,并在许多疾病的发病机制中发挥重要作用,尤其是在阿尔茨海默病和青光眼等神经退行性疾病中。青光眼主要与病理性眼压升高有关,是一种威胁和损害视神经及其视觉通路并最终导致视功能损害的眼病。随着对细胞焦亡参与眼病机制以及青光眼发病机制和治疗的关注度不断提高,研究发现细胞焦亡与青光眼密切相关。视网膜神经节细胞的细胞焦亡和小胶质细胞介导的细胞焦亡在青光眼的发展中具有重要地位。进一步了解细胞焦亡与青光眼之间的关系可能为青光眼治疗带来新的曙光。细胞焦亡机制可能为青光眼的发病机制和治疗提供新策略。
