摘要 近十余年来,载脂蛋白(ApoE)与低密度脂蛋白(LDL)受体(LDLr)基因敲除小鼠已成为研究脂代谢和动脉粥样硬化最为常用的模型。在这两种小鼠模型基础上,通过与不同的转基因、基因敲除小鼠杂交,产生了多种脂代谢紊乱和动脉粥样硬化小鼠模型,为发现调控血浆脂蛋白以及动脉粥样硬化发生的机制,创造了有利条件。此外,新的严重高甘油三酯血症小鼠模型也制备成功,本文笔者研究组研究了其中的脂蛋白脂酶缺陷模型与代谢性疾病的关系,得到了许多有意义的结果。而利用不同转基因和去基因小鼠作为供体,以及ApoE或LDL受体缺陷小鼠作为接受体的骨髓移植技术,则大大丰富了人们对于巨噬细胞中不同基因在动脉粥样硬化发生、发展和消退过程中作用的认识。动脉粥样硬化的易损斑块形成是近年来的一个研究热点,应用小鼠模型进行模拟也取得了一定的成功。然而,小鼠与人类在脂代谢和动脉粥样硬化中存在很大的种系差异,本文对此也予以评述。
