Atherosclerosis, characterized by dyslipidemia and severe inflammation, has become the main cause of cardiovascular disease. However, accurately and efficiently regulating lipid metabolism and relieving inflammation is a great challenge. Herein, we design a plaque/macrophage dual-targeting programmed atherosclerosis management strategy for synchronously regulating lipid metabolism and the macrophage phenotype. First, the biomimetic nanoparticles (named HA-ML@(H + R) NPs) were constructed by coloading rosuvastatin and hydroxysafflor yellow A into the hyaluronic acid (HA)-modified hybrid macrophage membrane-liposome NPs, enabling them to target plaques and macrophages simultaneously. The in vitro assay indicated that HA-ML@(H + R) NPs exhibited distinguishing antioxidant ability and reversed the macrophage phenotype from M1 to M2. Meanwhile, autophagy activation via downregulating the CD36 level promoted lipid metabolism for eliminating low-density lipoproteins. The in vivo study showed that HA-ML@(H + R) NPs exhibited therapeutic advantages in homocysteine (Hcy)-induced ApoE mice with atherosclerosis by effectively reducing the atherosclerotic plaque area and enhancing plaque stability, which was accompanied by the improvement of mice behaviors. Overall, this precise regulation of lipid metabolism and inflammation using a dual-targeted strategy provides a potentially effective method for the clinical treatment of atherosclerosis.
动脉粥样硬化以血脂异常和严重炎症为特征,已成为心血管疾病的主要原因。然而,准确有效地调节脂质代谢和减轻炎症是一项巨大挑战。在此,我们设计了一种斑块/巨噬细胞双靶向程序性动脉粥样硬化管理策略,用于同步调节脂质代谢和巨噬细胞表型。首先,通过将瑞舒伐他汀和羟基红花黄色A共载入透明质酸(HA)修饰的混合巨噬细胞膜-脂质体纳米粒中构建了仿生纳米粒(命名为HA-ML@(H + R) NPs),使其能够同时靶向斑块和巨噬细胞。体外实验表明,HA-ML@(H + R) NPs表现出显著的抗氧化能力,并将巨噬细胞表型从M1型逆转至M2型。同时,通过下调CD36水平激活自噬促进脂质代谢以清除低密度脂蛋白。体内研究表明,HA-ML@(H + R) NPs在同型半胱氨酸(Hcy)诱导的动脉粥样硬化ApoE小鼠中具有治疗优势,可有效减小动脉粥样硬化斑块面积并增强斑块稳定性,同时伴有小鼠行为的改善。总体而言,这种使用双靶向策略对脂质代谢和炎症进行的精确调节为动脉粥样硬化的临床治疗提供了一种潜在有效的方法。
