α-Synuclein is central to the Lewy body neuropathology of Parkinson's disease (PD), a devastating neurodegenerative disorder characterized by numerous motor and non-motor manifestations. The cardinal motor symptoms are linked to death of dopaminergic neurons in the nigrostriatal pathway. Here we ask why these neurons are preferentially susceptible to neurodegeneration in PD and how α-synuclein is involved. To address these questions we bring together recent findings from genome-wide association studies, which reveal the involvement of α-synuclein gene variants in sporadic PD, with recent studies highlighting important roles for α-synuclein in synaptic transmission and dopaminergic neuron physiology. These latest advances add to our understanding of PD etiology and provide a central link between the genetic findings and neurodegeneration observed in sporadic PD.

α-突触核蛋白和多巴胺处于帕金森病的十字路口



α-突触核蛋白是帕金森病 (PD) 路易体神经病理学的核心,帕金森病是一种毁灭性的神经退行性疾病,其特征是多种运动和非运动表现。主要运动症状与黑质纹状体通路中多巴胺能神经元的死亡有关。在这里,我们要问为什么这些神经元在帕金森病中更容易受到神经变性的影响,以及 α-突触核蛋白是如何参与其中的。为了解决这些问题,我们汇集了全基因组关联研究的最新发现,这些研究揭示了 α-突触核蛋白基因变异在散发性 PD 中的参与,最近的研究强调了 α-突触核蛋白在突触传递和多巴胺能神经元生理学中的重要作用。这些最新进展增加了我们对帕金森病病因学的理解,并提供了遗传发现和散发性帕金森病中观察到的神经变性之间的中心联系。
