[Abstract]  The deposition of misfolded, aggregated tau protein is a hallmark of several neurodegenerative diseases, collectively termed “tauopathies”. Tau pathology spreads throughout the brain along connected pathways in a prion-like manner. The process of tau pathology propagation across circuits is a focus of intense research and has been investigated in vivo in human post-mortem brain and in mouse models of the diseases, in vitro in diverse cellular systems including primary neurons, and in cell free assays using purified recombinant tau protein. Here we describe a protocol that takes advantage of a minimalistic neuronal circuit arrayed within a microfluidic device to follow the propagation of tau misfolding from a presynaptic to a postsynaptic neuron. This assay allows ... [摘要]  [摘要] 错折叠的聚集性tau蛋白的沉积是几种神经退行性疾病的标志,统称为“ tauopathies”。Tau病理以a病毒样方式沿着连接的路径在整个大脑中传播。tau病理学在整个电路中传播的过程是一项深入研究的重点,并且已在人体死后大脑和疾病小鼠模型中进行了体内研究,在包括原代神经元在内的各种细胞系统中进行了体外研究,并使用纯化的重组tau蛋白。在这里,我们描述了一种协议,该协议利用微流控设备中排列的简约神经元回路来跟踪tau错折叠从突触前神经元向突触后神经元的传播。该方法允许高分辨率成像以及释放和接收神经元的单独操作,因此有利于研究tau和其他错折叠蛋白的体外繁殖。

[背景 ] 错折叠的蛋白质在整个大脑中的传播是病理学在多种神经退行性疾病中传播的基础,包括阿尔茨海默氏病,帕金森氏症和Pri病毒病(Goedert 等人,2010;Davis 等人,2018; Hallinan 等人,2019a )。了解潜在机制可能有助于限制疾病进展,因此是深入研究的领域。存在几种体内和体外测定法来监测该过程,包括对过度表达的突变型人tau产生神经变性的小鼠模型(Allen 等人,2002; Ramsden 等人,2005; Santa Cruz 等人,2005; Gibbons 等人。等人,2017)。体外模型包括表达可监测聚集的生物传感器的细胞系(Kfoury ...
