帕金森病(PD)是世界上第二大常见的神经退行性疾病。其主要的神经病理学特征是黑质和含有α -突触核蛋白的蛋白包涵体(称为路易体)中多巴胺能神经元的变性。特发性PD的诊断仍然是基于临床标准的评估,导致诊断的准确性不足。此外,没有生物标志物可用于预测病程或监测对治疗方法的反应。到目前为止,α -突触核蛋白等候选蛋白质生物标志物未能改善帕金森病的诊断。体液中的循环microRNAs (miRNAs)是PD的有希望的生物标志物候选者,因为它们很容易通过非侵入性或微创性手术获得,并且它们的表达变化与PD相关的病理生理过程有关。随着miRNA分析方法的进步,最近发表了许多关于miRNA作为假定生物标志物的文章。在这里,我们讨论了不同体液作为miRNA生物标志物来源的适用性,强调了miRNA分析的技术方面,并概述了研究循环miRNA作为PD和其他帕金森综合征诊断生物标志物候选物的已发表研究。
Parkinson’s disease (PD) is the second most common neurodegenerative disorder worldwide. Its main neuropathological hallmarks are the degeneration of dopaminergic neurons in the substantia nigra and alpha-synuclein containing protein inclusions, called Lewy Bodies. The diagnosis of idiopathic PD is still based on the assessment of clinical criteria, leading to an insufficient diagnostic accuracy. Additionally, there is no biomarker available allowing the prediction of the disease course or monitoring the response to therapeutic approaches. So far, protein biomarker candidates such as alpha-synuclein have failed to improve diagnosis of PD. Circulating microRNAs (miRNAs) in body fluids are promising biomarker candidates for PD, as they are easily accessible by non- or minimally-invasive procedures and changes in their expression are associated with pathophysiological processes relevant for PD. Advances in miRNA analysis methods resulted in numerous recent publications on miRNAs as putative biomarkers. Here, we discuss the applicability of different body fluids as sources for miRNA biomarkers, highlight technical aspects of miRNA analysis and give an overview on published studies investigating circulating miRNAs as biomarker candidates for diagnosis of PD and other Parkinsonian syndromes.
