The therapeutic efficiency of active targeting nanoparticulate drug delivery systems (nano-DDS) is highly compromised by the plasma proteins adsorption on nanoparticles (NPs) surface, which significantly hinders cell membrane receptors to recognize the designed ligands, and provokes the off-target toxicity and rapid clearance of NPs . Herein, we report a novel dihydroartemisinin (DHA)-decorating nano-DDS that specifically recruits endogenous apolipoprotein E (apoE) on the NPs surface. The apoE-anchored corona is able to prolong PLGA-PEG2000-DHA (PPD) NPs circulation capability in blood, facilitate NPs accumulating in tumor cells by the passive enhanced permeability and retention (EPR) effect and low-density lipoprotein receptor (LDLr)-mediated target transport, and ultimately improve the antitumor activity. Our findings demonstrate that the strategy of regulated apoE-enriched corona ensures NPs an efficient LDLr-mediated tumor-homing chemotherapy.
主动靶向纳米颗粒药物递送系统(纳米药物递送系统,nano-DDS)的治疗效率因血浆蛋白吸附在纳米颗粒(NPs)表面而受到严重影响,这显著阻碍细胞膜受体识别设计的配体,并引发非靶向毒性和纳米颗粒的快速清除。在此,我们报道了一种新型的二氢青蒿素(DHA)修饰的纳米药物递送系统,该系统能在纳米颗粒表面特异性募集内源性载脂蛋白E(apoE)。载脂蛋白E锚定的冠层能够延长聚乳酸-羟基乙酸共聚物-聚乙二醇2000-二氢青蒿素(PPD)纳米颗粒在血液中的循环能力,通过被动增强的渗透和滞留(EPR)效应以及低密度脂蛋白受体(LDLr)介导的靶向转运促进纳米颗粒在肿瘤细胞中的积累,并最终提高抗肿瘤活性。我们的研究结果表明,调节富含载脂蛋白E的冠层的策略可确保纳米颗粒实现高效的低密度脂蛋白受体介导的肿瘤归巢化疗。
