Major Differences between the Self-Assembly and Seeding Behavior of Heparin-Induced and in Vitro Phosphorylated Tau and Their Modulation by Potential Inhibitors.
微管结合蛋白tau自组装为神经毒性寡聚体、纤维和成对螺旋丝,并在细胞间传播,是阿尔茨海默病及其他tau病的关键病理过程。调控tau自组装、抑制毒性聚集体形成与扩散是潜在治疗策略。体外研究tau自组装的难点在于tau在无翻译后修饰、聚集诱导剂或预成种子时不聚集;常用肝素等多聚阴离子诱导,但可能不能代表体内由异常磷酸化驱动的tau行为。...
