帕金森病(PD)的特征性脑病理学和运动及非运动症状已得到很好的证实。然而,关于这种疾病的原因及其过程的细节还不太清楚。动物模型极大地丰富了我们目前对这种疾病进展的理解。在各种基于神经毒素的PD模型中,1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP)小鼠模型是最常研究的模型。在这里,我们提供了一个概述的动态变化,黑质纹状体通路的MPTP小鼠模型的PD。病理生理事件,如减少纹状体多巴胺(DA)浓度和酪氨酸羟化酶(TH)蛋白的水平,TH阳性神经纤维的耗竭,TH阳性神经元的数量减少在黑质pars延髓(SNPC),神经胶质细胞的激活,解决。这篇文章将有助于开发PD的干预措施或治疗策略。
The characteristic brain pathology and motor and nonmotor symptoms of Parkinson's disease (PD) are well established. However, the details regarding the causes of the disease and its course are much less clear. Animal models have significantly enriched our current understanding of the progression of this disease. Among various neurotoxin-based models of PD, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model is the most commonly studied model. Here, we provide an overview of the dynamic changes in the nigrostriatal pathway in the MPTP mouse model of PD. Pathophysiological events, such as reductions in the striatal dopamine (DA) concentrations and levels of the tyrosine hydroxylase (TH) protein, depletion of TH-positive nerve fibers, a decrease in the number of TH-positive neurons in the substantia nigra pars compacta (SNpc), and glial activation, are addressed. This article will assist with the development of interventions or therapeutic strategies for PD.
