Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder. Among its pathologies, progressive loss of dopaminergic (DA) neurons in the substantia nigra is characteristic and contributes to many of the most severe symptoms of PD. Recent advances in induced pluripotent stem cell (iPSC) technology have made it possible to generate patient-derived DA neuronal cell culture and organoid models of PD. These models have contributed to understanding disease mechanisms and the identification of novel targets and therapeutic candidates. Still needed are better ways to model the age-related aspects of PD, as well as a deeper understanding of the interactions among disease-modifying genes and between genetic and environmental contributions to the etiology and progression of PD.
帕金森病(PD)是第二大常见的神经退行性疾病。在其病理学中,黑质中多巴胺能(DA)神经元的进行性丧失是其特征,并导致 PD 的许多最严重症状。诱导多能干细胞(iPSC)技术的最新进展使得生成患者来源的 DA 神经元细胞培养物和 PD 类器官模型成为可能。这些模型有助于理解疾病机制以及确定新的靶点和治疗候选物。仍然需要更好的方法来模拟 PD 的与年龄相关的方面,以及更深入地了解疾病修饰基因之间的相互作用以及遗传和环境因素对 PD 的病因和进展的贡献。
