Alzheimer's disease (Alzheimer's disease, AD) is a progressive neurological disorder characterized by memory loss and cognitive impairment. It is characterized by the formation of tau protein neurofibrillary tangles and β-amyloid plaques. Recent studies have found that mitochondria in neuronal cells of AD patients exhibit various dysfunctions, including reduced numbers, ultrastructural changes, reduced enzyme activity, and abnormal kinetics. These abnormal mitochondria not only lead to the loss of normal neuronal cell function, but are also a major driver of AD progression. In this review, we will focus on the advances of mitochondria and their multi-omics in AD research, with particular emphasis on how mitochondrial dysfunction in AD drives disease progression. At the same time, we will focus on summarizing how mitochondrial genomics technologies have revealed specific details of these dysfunctions and how therapeutic strategies targeting mitochondria may provide new directions for future AD treatments. By delving into the key mechanisms of mitochondria in AD related to energy metabolism, altered kinetics, regulation of cell death, and dysregulation of calcium-ion homeostasis, and how mitochondrial multi-omics technologies can be utilized to provide us with a better understanding of these processes. In the future, mitochondria-centered therapeutic strategies will be a key idea in the treatment of AD.
阿尔茨海默病(Alzheimer's disease,AD)是一种进行性神经退行性疾病,其特征是记忆丧失和认知障碍。它的特征是形成 tau 蛋白神经原纤维缠结和 β-淀粉样斑块。最近的研究发现,AD 患者神经元细胞中的线粒体表现出各种功能障碍,包括数量减少、超微结构改变、酶活性降低和动力学异常。这些异常的线粒体不仅导致正常神经元细胞功能的丧失,而且是 AD 进展的主要驱动因素。在这篇综述中,我们将重点介绍线粒体及其在 AD 研究中的多组学的进展,特别强调 AD 中线粒体功能障碍如何驱动疾病进展。同时,我们将重点总结线粒体基因组学技术如何揭示这些功能障碍的具体细节,以及靶向线粒体的治疗策略如何为未来的 AD 治疗提供新的方向。通过深入研究线粒体与 AD 相关的能量代谢、动力学改变、细胞死亡调控和钙离子平衡失调等关键机制,以及线粒体多组学技术如何帮助我们更好地理解这些过程。未来,以线粒体为中心的治疗策略将是 AD 治疗的一个关键思路。
