摘要:

阿尔茨海默病是痴呆的主要原因,其特征是神经病理学的变化,如淀粉样斑块、突触和神经元变性以及神经原纤维缠结。尽管淀粉样斑块是阿尔茨海默病在中枢神经系统和外周器官中的重要特征,但靶向清除中枢神经系统中的β-淀粉样蛋白在阿尔茨海默病治疗中疗效有限。阿尔茨海默病患者常见代谢异常。肝脏是参与β-淀粉样蛋白代谢的主要外周器官,在阿尔茨海默病的病理生理方面中起着至关重要的作用。值得注意的是,肝脏中胆固醇代谢受损可能会加剧阿尔茨海默病的发展。因此此次综述系统地回顾了阿尔茨海默病的潜在病因,并阐明了肝脏胆固醇代谢在β-淀粉样蛋白清除中的作用。文章提出,恢复肝脏中正常的胆固醇代谢可能是治疗阿尔茨海默病的一种潜在治疗策略。

Abstract: Alzheimer’s disease, the primary cause of dementia, is characterized by neuropathologies, such as amyloid plaques, synaptic and neuronal degeneration, and neurofibrillary tangles. Although amyloid plaques are the primary characteristic of Alzheimer’s disease in the central nervous system and peripheral organs, targeting amyloid-beta clearance in the central nervous system has shown limited clinical efficacy in Alzheimer’s disease treatment. Metabolic abnormalities are commonly observed in patients with Alzheimer’s disease. The liver is the primary peripheral organ involved in amyloid-beta metabolism, playing a crucial role in the pathophysiology of Alzheimer’s disease. Notably, impaired cholesterol metabolism in the liver may exacerbate the development of Alzheimer’s disease. In this review, we explore the underlying causes of Alzheimer’s disease and elucidate the role of the liver in amyloid-beta clearance and cholesterol metabolism. Furthermore, we propose that restoring normal cholesterol metabolism in the liver could represent a promising therapeutic strategy for addressing Alzheimer’s disease.
