铁是线粒体功能和稳态的关键元素,这对维持神经系统也至关重要,但过多的铁会促进氧化应激。大量证据表明,脑中异常的铁积累与各种神经变性疾病如亨廷顿病、阿尔茨海默病、帕金森病和弗里德赖希共济失调有关。然而,目前还不清楚不规则的铁状态如何有助于神经元疾病的发展。因此,目前的审查提供了一个更新的因果关系的影响,铁超载的发展和进展的神经退行性疾病,并讨论了重要的作用,线粒体铁稳态在这些疾病的条件。此外,这篇综述讨论了潜在的治疗靶点,用于治疗铁超载相关的神经退行性疾病。
Iron is a key element for mitochondrial function and homeostasis, which is also crucial for maintaining the neuronal system, but too much iron promotes oxidative stress. A large body of evidence has indicated that abnormal iron accumulation in the brain is associated with various neurogenerative diseases such as Huntington’s disease, Alzheimer’s disease, Parkinson’s disease, and Friedreich’s ataxia. However, it is still unclear how irregular iron status contributes to the development of neuronal disorders. Hence, the current review provides an update on the causal effects of iron overload in the development and progression of neurodegenerative diseases and discusses important roles of mitochondrial iron homeostasis in these disease conditions. Furthermore, this review discusses potential therapeutic targets for the treatments of iron overload-linked neurodegenerative diseases.
