中文摘要
项目摘要
帕金森病(Parkinson's disease,PD)是第二大常见的与衰老相关的神经退行性疾病。的
疾病的特征在于归因于中脑多巴胺能神经元的损失的运动症状,
它们对基底神经节宏回路的神经支配。在PD患者和动物模型中,
表现出异常的活动模式,包括外球神经元的同步、有节奏的爆发
苍白球(GPe)。然而,在帕金森病中形成这些同步的和暂时的结构化事件的因素,
仍然未知。我们的总体假设是,GABA能输入塑造了活动水平、模式和
GPe内小清蛋白和Npas 1神经元的同步性。使用细胞计数器和电路计数器特定的工具,我们
将研究纹状体输入和局部侧支输入与小清蛋白和Npas 1神经元的连接
在GPe内,以及这种连接在PD的慢性6-羟多巴胺损伤模型中如何改变。
此外,我们将确定小白蛋白和Npas 1神经元及其纹状体输入如何参与
运动功能和功能障碍。 拟议中的实验利用了尖端技术和
这些方法将克服迄今为止阻碍进展的障碍。这些方法包括病毒
基因递送、Cre Blox重组、光遗传学、化学遗传学、电生理学和纤维光度学。

研究PD的潜在机制,并在此过程中促进PD患者新疗法的开发。
英文摘要
Project Summary
Parkinson’s disease (PD) is the second most common neurodegenerative disease associated with aging. The
disease is characterized by motor symptoms attributed to the loss of mesencephalic dopaminergic neurons and
their innervation to the basal ganglia macrocircuit. In patients and animal models of PD, this macrocircuit
exhibits aberrant activity patterns including synchronous, rhythmic bursting of neurons in the external globus
pallidus (GPe). However, the factors that shape these synchronous and temporallystructured events in PD
remain unknown. It is our overarching hypothesis that GABAergic inputs shape the activity level, pattern, and
synchrony of both parvalbumin and Npas1 neurons within the GPe. Using cell and circuitspecific tools, we
will investigate the connectivity of striatal inputs and local collateral inputs to parvalbumin and Npas1 neurons
within the GPe and how this connectivity becomes altered in the chronic 6OHDA lesion model of PD.
Furthermore, we will determine how parvalbumin and Npas1 neurons and their striatal inputs are involved in
motor function and dysfunction. The proposed experiments capitalize on a combination of cuttingedge
approaches that will overcome obstacles that had impeded progress until now. These approaches include viral
gene delivery, Crelox recombination, optogenetics, chemogenetics, electrophysiology, and fiber photometry.
Additionally, anatomical, analytical, and computational approaches will be used to help interpret research
findings. The successful achievement of these aims will significantly advance our understanding of the
mechanisms underlying PD and, in doing so, promote the development of new therapies for PD patients.
