阿尔茨海默病(AD)是最常见的神经退行性疾病,其特征在于记忆、认知和行为的进行性损害,并最终导致死亡。Alzheimer病的组织病理学改变包括脑内神经元和突触丢失、细胞外老年斑形成和细胞内神经元缠结。多种证据表明,氧化应激不仅在细胞病理学之前强烈参与阿尔茨海默病的早期阶段,而且在诱导和激活多种细胞信号通路中起重要作用,这些细胞信号通路有助于毒性物质的损伤形成,然后促进阿尔茨海默病的发展。多年的研究表明,抗氧化剂治疗在临床前研究中取得了普遍的成功。因此,本文主要集中在阿尔茨海默病的常用抗氧化治疗的最新进展,从而为未来潜在的神经退行性疾病的抗氧化治疗策略提供指示。
Alzheimer's disease (AD) is the most common neurodegenerative disease featuring progressive impairments in memory, cognition, and behavior and ultimately leads to death. The histopathological changes of Alzheimer's disease include neuronal and synaptic loss, formation of extracellular senile plaques and intracellular neurofibrillary tangles in brain. Multiple lines of evidence indicate that oxidative stress not only strongly participates in an early stage of Alzheimer's disease prior to cytopathology, but plays an important role in inducing and activating multiple cell signaling pathways that contribute to the lesion formations of toxic substances and then promotes the development of Alzheimer's disease. Many years of studies show that antioxidant therapies have enjoyed general success in preclinical studies. Therefore, this paper mainly focuses on the recent developments of common used antioxidant therapies for Alzheimer's disease and thus provides indications for future potential antioxidant therapeutic strategies of neurodegenerative diseases.
