1407-PSMC5基因变异与神经发育蛋白酶体病研究

from 聊聊Sci

这篇文章探讨了PSMC5基因变异如何引发一种复杂的综合征型神经发育障碍。研究者通过分析数十名患者的临床表现,结合果蝇、大鼠及人类诱导多能干细胞模型,揭示了该基因对蛋白酶体功能的至关重要性。PSMC5功能缺失会导致细胞内受损蛋白堆积,进而引发线粒体受损、脂质代谢紊乱以及异常的免疫信号激活。在神经系统中,这些病理变化破坏了突触平衡和神经前体细胞的分化,临床上表现为发育迟缓、智力障碍及独特的面部特征。此外,研究还利用集成应激反应抑制剂成功缓解了细胞的炎症反应,为这类罕见病提供了潜在的治疗方向。References:Küry S, Stanton J E, van Woerden G M, et al.
