Parkinson's disease (PD) is a mysterious, chronic, multi-factorial and progressive disorder of the nervous system that is characterized by the selective loss of dopamine-producing cells of the substantia nigra leading to dopamine deficiency in the striatum. PD is exemplified by oxidative stress, α-synuclein accumulation, mitochondrial dysfunction, defective ubiquitin proteasome system, aberrant autophagy, inflammation, and atypical apoptosis, which eventually lead to slowness of movement, resting tremor, stiffness, and loss of balance. Despite incomprehensible etiology, timely diagnosis, and permanent cure, a handful of synthetic and natural agents rescue from the symptomatic features and delay disease progression. At low doses, a natural polyphenol, trans-3,5,4'-trihydroxystilbene (resveratrol), delays neurodegeneration in the cellular and animal models and lessens oxidative stress, mitochondrial dysfunction, aberrant apoptosis, and defective autophagy. The present article explains neuroprotective efficacy, advantages, and downsides of resveratrol in the conventional and preclinical models. This piece of writing also examines its probable neuroprotective mechanisms and constraints of realistic recital in clinical investigations and likely endeavors to minimize apprehensions.
帕金森病(PD)是一种神秘的、慢性的、多因素的进行性神经系统疾病,其特征是黑质中产生多巴胺的细胞选择性丧失,导致纹状体中多巴胺缺乏。PD的表现包括氧化应激、α-突触核蛋白积累、线粒体功能障碍、泛素蛋白酶体系统缺陷、异常自噬、炎症和非典型凋亡,这些最终会导致运动迟缓、静止性震颤、僵硬和平衡丧失。尽管病因不明、难以及时诊断和根治,但一些合成药物和天然药物可缓解症状并延缓疾病进展。低剂量的天然多酚反式-3,5,4'-三羟基芪(白藜芦醇)在细胞和动物模型中可延缓神经退行性变,并减轻氧化应激、线粒体功能障碍、异常凋亡和自噬缺陷。本文阐述了白藜芦醇在传统模型和临床前模型中的神经保护作用、优势和不足。本文还探讨了其可能的神经保护机制以及临床研究中实际应用的局限性,并可能努力减少相关担忧。
