1447-人源类器官视网膜变性与药物筛选模型
from 聊聊Sci
这篇文章介绍了一项关于干性老年性黄斑变性(AMD)的前沿研究,研究者利用人诱导多能干细胞培育出三维视网膜类器官(RO)模型。该模型成功模拟了AMD中关键的光感受器细胞变性过程,并发现香烟提取物(CSE)会引发氧化应激、线粒体功能障碍及细胞死亡。研究进一步揭示,光感受器细胞的凋亡与铁死亡共同驱动了病理损伤。此外,该团队开发了一套荧光定量检测技术,能够高效评估药物疗效。这一创新的人源化平台为开发预防失明的神经保护疗法提供了重要的临床前工具。References:Parween S, Saviola A J, Howell A C, et al.
