摘要:

帕金森病(PD)的病因十分复杂,单个动物模型很难完全模拟其病理特征。此次研究拟对不同的帕金森病小鼠模型(MPTP诱导模型、α-Syn A53T转基因模型和MitoPark模型)的行为、帕金森病样病理以及基因和蛋白质表达谱进行全面分析。可见3种帕金森病小鼠模型都表现出运动障碍,尤其是MitoPark小鼠呈年龄相关性恶化。在病理学方面,所有小鼠模型均可见黑质纹状体通路损伤,但神经胶质细胞活化模式却不同。其中,16个月龄α-Syn A53T小鼠黑质存在pS129-α-Syn阳性信号,但所有模型中均未见α-Syn聚集体。在分子机制方面,RNA测序和蛋白质组学揭示了帕金森病小鼠模型中基因和蛋白质表达的显著变化,显示不同模型存在独特和共同的特征。鉴定出5种常见的差异表达基因(Ifi27l2a、Ifitm3、Oasl2、Rtp4和Ankk1)和2种常见的差异表达蛋白(Timm8a1和Sephs1)。功能富集分析表明,免疫反应、细胞因子和神经递质转运在帕金森病发病机制中至关重要。值得注意的是,在不同模型中可见多种与铁相关的细胞损伤(铁死亡)相关的差异表达基因,且MitoPark小鼠存在IL17通路激活变化。上述发现从多维度阐明不同帕金森病模型病理模拟能力和常见机制的共性和特异性,这将提供了对帕金森病多方面特征的洞察,并为疾病机制探索模型选择的提供参考。

Abstract: The causes of Parkinson’s disease are complex, and it is difficult for a single animal model to fully mimic its pathological characteristics. In this study, a comprehensive analysis of behaviors, Parkinson’s disease–like pathologies, and gene and protein expression profiles was carried out in three mouse models of disease: 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine-induced, α-synuclein (α-syn) A53T transgenic, and MitoPark, revealing both shared and model-specific pathogenic pathways to guide model selection and identify potential therapeutic targets. All three Parkinson’s disease models exhibited motor impairments, with particularly pronounced age-related decline observed in MitoPark mice. Pathologically, nigrostriatal pathway damage was observed in all models, yet with distinct patterns of glial cell activation. Sixteen-month-old α-syn A53T mice displayed a few pS129- α-syn-positive signals in the substantia nigra, while no α-syn aggregates were observed in any of the models. RNA sequencing and proteomics analysis revealed significant changes in gene and protein expression, with both unique and common features among the three models. Five common differentially expressed genes (Ifi27l2a, Ifitm3, Oasl2, Rtp4, and Ankk1) and two common differentially expressed proteins (Timm8a1 and Sephs1) were identified. Functional enrichment analysis indicated that immune responses, cytokines, and neurotransmitter transport were crucial in Parkinson’s disease pathogenesis. Notably, multiple iron-related cell damage (ferroptosis)-related differentially expressed genes were identified across all three models, while interleukin 17 pathway activation was altered in MitoPark mice. In summary, we analyzed the commonalities and specificities of pathological simulation capabilities and common disease mechanisms in different mouse models of Parkinson’s disease from multiple perspectives. Our findings offer valuable insights into the multifaceted characteristics of Parkinson’s disease and will assist in model selection for mechanistic exploration in the future.
