Autophagy is a major regulatory cellular mechanism which gives the cell an ability to cope with some of the destructive events that normally occur within a metabolically living cell. This is done by maintaining the cellular homeostasis, clearance of damaged organelles and proteins and recycling necessary molecules like amino acids and fatty acids. There is a wide array of factors that influence autophagy in the state of health and disease. Disruption of these mechanisms may not only give rise to several autophagy-related disease, but also it can occur as the result of intracellular changes induced during disease pathogenesis causing exacerbation of the disease. Our knowledge is increasing regarding the role of autophagy and its mechanisms in the pathogenesis of various neurodegenerative diseases such as multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease and Amyotrophic lateral sclerosis. Indeed, getting to know about the pathways of autophagy and its regulation can provide the basis for designing therapeutic interventions. In the present paper, we review the pathways of autophagy, its regulation and the possible autophagy-targeting interventions for the treatment of neurodegenerative disorders.
自噬是一种主要的细胞调节机制,使细胞能够应对一些在代谢活跃的细胞中通常发生的破坏性事件。这是通过维持细胞内稳态、清除受损的细胞器和蛋白质以及回收必要的分子(如氨基酸和脂肪酸)来实现的。有许多因素会影响健康和疾病状态下的自噬。这些机制的破坏不仅会导致几种与自噬相关的疾病,而且还可能是由于疾病发病过程中诱导的细胞内变化引起的,从而导致疾病的恶化。我们对自噬及其在多种神经退行性疾病(如多发性硬化症、帕金森病、阿尔茨海默病、亨廷顿病和肌萎缩侧索硬化症)发病机制中的作用及其机制的认识正在不断增加。事实上,了解自噬的途径及其调控可以为设计治疗干预提供基础。在本文中,我们综述了自噬的途径、调控及其在神经退行性疾病治疗中的可能的自噬靶向干预措施。
