    Association of p53 with Neurodegeneration in Parkinson’s Disease by Qiang Luo, Wei Sun, Yi-Fan Wang, Ji Li, Da-Wei Li

    Published 2022-01-01
    “…Recent studies have revealed that p53 levels and activity are substantially increased in affected neurons in cellular and animal models of Parkinson’s disease (PD) as well as in the brains of PD patients. p53 activation in response to neurodegenerative stress is closely associated with the degeneration of dopaminergic neurons accompanied by mitochondrial dysfunction, reactive oxygen species (ROS) production, abnormal protein aggregation, and impairment of autophagy, and these pathogenic events have been implicated in the pathogenesis of PD. …”
