Animal models of Parkinson's disease (PD) that more closely exhibit the chronic neuropathology seen in the human condition are needed in order to reveal processes involved with progressive neurodegeneration and for testing potential interventions for retarding dopamine (DA) neuronal loss. Here we describe the recently developed chronic rat model of PD in which 1-methyl-4-phenylpyridinium ion (MPP(+)) is infused chronically into the lateral cerebral ventricle. We review features of this model that include loss of nigral DA neurons, swollen and abnormal mitochondria, striatal inclusion-like bodies and microgliosis. Advantages as well as limitations of the model are addressed.
为了揭示与进行性神经退行性变相关的过程以及测试延缓多巴胺(DA)神经元丢失的潜在干预措施,需要更紧密地展现人类帕金森病(PD)慢性神经病理学特征的动物模型。在此,我们描述了最近开发的慢性大鼠PD模型,其中1-甲基-4-苯基吡啶离子(MPP(+))被长期注入大脑侧脑室。我们回顾了该模型的特征,包括黑质DA神经元丢失、线粒体肿胀和异常、纹状体包涵体样小体以及小胶质细胞增生。还讨论了该模型的优点和局限性。
