Abstract

A circuit-based gene therapy strategy for Parkinson's disease (PD) has been shown to significantly reverse core symptoms in both murine and primate PD models. Here, we present a comprehensive workflow to specifically manipulate dopamine receptor D-expressing medium spiny neurons by retrograde adeno-associated virus (AAV) transduction and chemogenetic activation using a designer toolkit. We describe steps for AAV injections and PD primate model induction. We then detail behavioral measurements to assess the therapeutic efficacy of the therapy for motor symptoms.

摘要

一种基于回路的帕金森病（PD）基因治疗策略已被证明能在小鼠和灵长类PD模型中显著逆转核心症状。在此，我们展示了一个全面的工作流程，通过逆行腺相关病毒（AAV）转导和使用设计工具包进行化学遗传激活，特异性地操纵表达多巴胺受体D的中等棘状神经元。我们描述了AAV注射和PD灵长类模型诱导的步骤。然后，我们详细介绍行为测量方法，以评估该疗法对运动症状的治疗效果。
