Zhongshan Daxue xuebao. Yixue kexue ban正常眼压性青光眼（NTG）是原发性开角型青光眼（POAG）的独立亚型，特征为眼压正常（＜21 mmHg）但出现进行性视神经病变、视网膜神经节细胞（RGC）凋亡及视野缺损。其发病机制主要为非眼压依赖，核心涉及以基因与线粒体为中心的过程，包括RGC退变、神经炎症、线粒体功能障碍和遗传易感性。基于此，本文系统梳理NTG的非眼压依赖、基因驱动机制，重点解析OPTN、TBK1、FOXC1与OPA1如何通过线粒体功能紊乱、胶质细胞激活、炎症信号、细胞凋亡与轴突退化等途径导致RGC损伤。其中 ...

Zhongshan Daxue xuebao. Yixue kexue ban随着全球人口老龄化进程的加快，肌少症作为一种以骨骼肌质量、力量与躯体功能持续性下降为特征的老年综合征，已成为严重威胁老年人健康和生活质量的重要公共卫生问题。其发生发展过程涉及多层次、跨系统的细胞与分子机制。近年来研究发现，程序性细胞死亡（PCD）在骨骼肌稳态维持、代谢调节与组织修复中发挥核心作用。凋亡、自噬、焦亡与铁死亡等典型PCD形式通过活性氧（ROS）积聚、线粒体功能障碍与铁稳态破坏等关键节点相互串扰，驱动肌纤维丢失、肌肉功能减退及慢性炎症反应，是肌少症发生发展的重要病理基础 ...

髓系细胞触发受体２在认知功能障碍中相关机制的研究进展 [PDF]
神经免疫系统对中枢神经系统的发育、衰老和损伤至关重要，逐渐成为人们研究的热点。髓系细胞触发受体２（TREM2）是免疫球蛋白超家族的一种跨膜受体，在中枢神经系统中主要表达于小胶质细胞。越来越多的研究表明，靶向TREM2对改善阿尔兹海默症、血管性痴呆、帕金森病、术后认知功能障碍、肥胖等疾病相关的认知功能障碍有很大的潜力。然而，其在认知功能障碍中的具体作用尚缺乏系统性的总结。故本文综述了TREM2在认知功能障碍中相关机制的最新研究进展 ...
