Low-density lipoprotein receptor (LDLR) and metabolic syndrome (MS) are closely correlated. Changes in LDLR expression, feedback regulation and degradation, impacts of LDLR deficiency on blood lipid levels, roles of LDLR in islet β cell dysfunction and cholesterol homeostasis dysregulation, expression of LDLR gene nuclear transcription factors and polymorphism of LDLR gene segments are all involved in the development of specific components of MS. In recent years, a variety of targets and intervention mechanisms in relation to LDLR and MS have been extensively studied. Knowledge about association between LDLR and MS may contribute to the development of strategies for prevention and treatment of MS. This article reviews the update on the association between LDLR and MS.
低密度脂蛋白受体（LDLR）与代谢综合征（MS）关系密切。LDLR的表达量、反馈调节水平和降解水平的变化，LDLR缺陷对血脂水平的影响，LDLR在胰岛β细胞损伤和胆固醇稳态失调中的作用，LDLR基因核转录因子的表达以及基因片段的多态性等均与MS特定组分的发生、发展存在一定的相关性。近年来，多个与LDLR及MS相关的靶点和干预机制得到了广泛研究。了解LDLR与MS的相关性，对MS的防治具有十分重要的意义。本文就LDLR与MS的相关性研究进展作一综述。
