ATP结合盒转运体G1与动脉粥样硬化的研究进展

摘要

The adenosine triphosphate (ATP)-binding cassette transporter G1 (ABCG1),a member of the superfamily of ATP-binding cassette transporters,is involved in the efflux of cholesterol and phospholipids from cells,and it maintains the intracellular hpid homeostasis.ABCG1 deficiency results in foam cell formation,endothelial dysfunction,and inflammatory reaction,and it further leads to the development and progression of atherosclerosis.However,the role of ABCG1 in atherosclerosis in animal experiments and human studies is still a debatable matter.In this paper,the recent findings on the role of ABCG1 in atherosclerotic disease are reviewed.%ATP结合盒转运体G1 (ABCG1)是人类ATP结合盒转运体超家族的成员之一,可促进细胞内的胆固醇和磷脂外流,维持细胞脂质稳态平衡.ABCG1缺乏可参与泡沫细胞形成、内皮细胞功能紊乱和炎症反应等,进而影响动脉粥样硬化的形成和发展.但是无论在动物实验还是人体研究,ABCG1在动脉粥样硬化中的作用都有争议,本文针对ABCG1在动脉粥样硬化疾病中的研究进展进行综述.
