Mitochondria, essential organelles responsible for cellular energy production, emerge as a key factor in the pathogenesis of neurodegenerative disorders. This review explores advancements in mitochondrial biology studies that highlight the pivotal connection between mitochondrial dysfunctions and neurological conditions such as Alzheimer's, Parkinson's, Huntington's, ischemic stroke, and vascular dementia. Mitochondrial DNA mutations, impaired dynamics, and disruptions in the ETC contribute to compromised energy production and heightened oxidative stress. These factors, in turn, lead to neuronal damage and cell death. Recent research has unveiled potential therapeutic strategies targeting mitochondrial dysfunction, including mitochondria targeted therapies and antioxidants. Furthermore, the identification of reliable biomarkers for assessing mitochondrial dysfunction opens new avenues for early diagnosis and monitoring of disease progression. By delving into these advancements, this review underscores the significance of understanding mitochondrial biology in unraveling the mechanisms underlying neurodegenerative disorders. It lays the groundwork for developing targeted treatments to combat these devastating neurological conditions.
线粒体是负责细胞能量产生的重要细胞器,已成为神经退行性疾病发病机制中的关键因素。本综述探讨了线粒体生物学研究的进展,这些进展突出了线粒体功能障碍与诸如阿尔茨海默病、帕金森病、亨廷顿病、缺血性中风和血管性痴呆等神经疾病之间的关键联系。线粒体DNA突变、动力学受损以及电子传递链的破坏导致能量产生受损和氧化应激加剧。这些因素进而导致神经元损伤和细胞死亡。最近的研究揭示了针对线粒体功能障碍的潜在治疗策略,包括线粒体靶向治疗和抗氧化剂。此外,可靠的线粒体功能障碍评估生物标志物的鉴定为疾病的早期诊断和进展监测开辟了新途径。通过深入研究这些进展,本综述强调了理解线粒体生物学在揭示神经退行性疾病潜在机制方面的重要性。它为开发针对性治疗方法以对抗这些毁灭性的神经疾病奠定了基础。
