摘要

Parkinson's disease (PD) is a neurodegenerative disease with a long preclinical phase.The continuous loss of dopaminergic (DA) neurons is one of the pathogenic hallmarks of PD.Diagnosis largely depends on clinical observation,but motor dysfunctions do not emerge until 70％-80％ of the nigrostriatal nerve terminals have been destroyed.Therefore,a biomarker that indicates the degeneration of DA neurons is urgently needed.Transcription factors are sequence-specific DNA-binding proteins that regulate RNA synthesis from a DNA template.The precise control of gene expression plays a critical role in the development,maintenance,and survival of cells,including DA neurons.Deficiency of certain transcription factors has been associated with DA neuron loss and PD.In this review,we focus on some transcription factors and discuss their structure,function,mechanisms of neuroprotection,and their potential for use as biomarkers indicating the degeneration of DA neurons.
