The brain, as one of the most lipid-rich organs, heavily relies on lipid transport and distribution to maintain homeostasis and neuronal function. Lipid transport mediated by lipoprotein particles, which are complex structures composed of apolipoproteins and lipids, has been thoroughly characterized in the periphery. Although lipoproteins in the central nervous system (CNS) were reported over half a century ago, the identification of as the strongest genetic risk factor for Alzheimer's disease has accelerated investigation of the biology and pathobiology of lipoproteins in the CNS. This review provides an overview of the different components of lipoprotein particles, in particular apolipoproteins, and their involvements in both physiological functions and pathological mechanisms in the CNS.
大脑作为脂质含量最丰富的器官之一,严重依赖于脂质的运输和分布来维持其体内平衡和神经元功能。由载脂蛋白和脂质组成的脂蛋白颗粒介导的脂质运输在外周组织中得到了深入研究。尽管半个多世纪前就已经报道了中枢神经系统(CNS)中的脂蛋白,但作为阿尔茨海默病最强遗传风险因素的 的发现,加速了对 CNS 中脂蛋白的生物学和病理生物学的研究。本综述概述了脂蛋白颗粒的不同成分,特别是载脂蛋白,以及它们在 CNS 的生理功能和病理机制中的作用。
