1099-小鼠脱髓鞘模型与多发性硬化症损伤的比较转录组分析

from 聊聊Sci

这项研究通过单细胞转录组学分析,深入比较了两种常用的多发性硬化症(MS)小鼠模型——杯生蛋白(CPZ)和溶血磷脂酰胆碱(LPC)模型,与人类MS病变之间的异同。研究发现,CPZ模型能更好地模拟人类病变中观察到的应激态少突胶质细胞,其特征是细胞代谢和基因毒性损伤;而两种小鼠模型在再髓鞘化阶段均表现出一种保守的免疫反应性状态。此外,尽管小鼠模型能够捕获核心的小胶质细胞激活模式,但它们无法完全体现人类MS病变中高度复杂的细胞异质性。这些研究成果为科学家策略性地选择和利用动物模型来研究神经髓鞘损伤与修复提供了重要的分子图谱和理论框架。References:Aboelnour E L, Vanoverbeke V R, Maupin E A, et al.
