944-Lecanemab通过微胶囊重编程清除淀粉样蛋白机制研究

from 聊聊Sci

这项研究深入探讨了阿尔茨海默病药物Lecanemab通过小胶质细胞清除淀粉样蛋白(Aβ)的具体机制。研究人员通过人类小胶质细胞移植模型发现,该药物必须通过其Fc片段激活细胞的效应功能,才能有效减少脑内的斑块积累。转录组分析进一步揭示,Lecanemab能诱导一种特定的基因表达程序,显著增强细胞的吞噬作用和溶酶体降解能力。研究特别强调了SPP1(骨桥蛋白)在这一清除过程中的关键驱动作用,证明其能提升小胶质细胞的保护性功能。这些发现不仅解释了为何该药物比其他抗体更有效,还为优化阿尔茨海默病的免疫疗法提供了重要思路。References:Albertini G, Zielonka M, Cuypers M L, et al.
