阿尔茨海默病(AD)等神经退行性疾病有一个共同的致病特征,即大脑蛋白聚集体的积累。在阿尔茨海默病中,tau 蛋白的积累是疾病进展的一个关键指标,这些蛋白聚集体的某些特征与朊病毒疾病相似。快速分析 tau 蛋白迁移等过程对于研究疾病进展至关重要。然而,由于缺乏研究毒性蛋白扩散的实验模型,了解其驱动机制变得十分困难。疾病模型与机制》(Disease Models & Mechanisms)杂志上的一项研究介绍了一种新的转基因果蝇模型,用于监测tau蛋白在大脑中的贩运和扩散。利用这一模型,研究小组确定了特定的基因改变,包括敲除GSK-3β,从而影响tau的贩运并减少其扩散。这些结果表明,果蝇是研究tau蛋白扩散的合适模型,也是更好地理解其背后机制和确定疾病疗法的潜在有用工具:Bankapalli, K. et al.Model.Mech.17, DMM050858 (2024)
