    摘要:

    帕金森病(Parkinson’s Disease,PD)是一种慢性的、进行性的神经退行性疾病,主要影响中枢神经系统的运动功能。由于其复杂的发病机制和缺乏有效的治疗方法,PD的研究一直是神经科学领域的热点之一。近年来,随着科学技术的不断进步,PD的动物模型研究取得了显著的进展。神经毒素模型可见明显多巴胺(Dopamine,DA)能神经元的损伤,多用于神经保护类药物的筛选但未见其病理特征。转基因模型有利于发现潜在治疗靶点但未见明显DA能神经元退化。神经毒素和转基因模型的结合可以克服其病理缺点,造成更多运动表型及非运动症状。α-突触核蛋白诱导模型可出现明显病理蛋白的聚集。细胞模型可在体外实现病理特征的重现,并作为药物动物模型实验前的筛选。近年来,随着Braak假说流行,越来越多的研究表明PD更可能是一种综合征,对其非运动症状(non-motor symptoms,NMS)的动物模型研究有望在疾病前期发现有效生物标志物,并为最令人丧失能力的非运动症状提供治疗方法。本文将综述各种动物模型的优势及其局限性,旨在为研究人员基于实验目的选择实验模型提供参考,并以期为疾病发病机制的深入理解和新治疗方法的开发提供参考。

    Abstract:

    Parkinson's disease(PD) is a chronic, progressive neurodegenerative disease that primarily affects the motor function of the central nervous system. Due to its complex pathogenesis and lack of effective treatments, the study of PD has been one of the hot topics in the field of neuroscience. In recent years, with the continuous progress of science and technology, remarkable progress has been made in the study of animal models of PD. The neurotoxin model showed obvious damage to dopaminergic neurons, which was mostly used for the screening of neuroprotective drugs, but no pathological features were found. Transgenic models are beneficial for the discovery of potential therapeutic targets, but no significant dopamine neurodegeneration has been observed. The combination of neurotoxins and transgenic models can overcome their pathological shortcomings, resulting in more motor phenotypes and non-motor symptoms. α-synuclein-inducible models can show significant aggregation of pathological proteins. Cell models can be reproduced in vitro for the reproducibility of pathological features and used as pre-screening for animal models of drugs. In recent years, with the popularity of the Braak hypothesis, more and more studies have shown that PD is more likely to be a syndrome, and animal models of non-motor symptoms of PD are expected to identify effective biomarkers in the pre-disease stage and provide treatments for the most disabling non-motor symptoms. In this review, we will review the advantages and limitations of various animal models, aiming to provide a reference for researchers to select experimental models based on experimental purposes, and to provide a reference for an in-depth understanding of disease pathogenesis and the development of new treatments.
