炎症是动脉粥样硬化的关键特征,也是治疗的靶点。他汀类药物具有有效的抗炎特性,但由于全身生物利用度低,口服他汀类药物治疗无法充分利用这些特性。在这里,我们提出了一种可注射的重组高密度脂蛋白(rHDL)纳米颗粒载体车辆,提供他汀类药物动脉粥样硬化斑块。我们证明了他汀-rHDL在体外的抗炎作用,并表明这种作用是通过抑制甲羟戊酸途径介导的。我们还在载脂蛋白E基因敲除小鼠动脉粥样硬化模型中应用他汀类-rHDL纳米颗粒,并显示它们在动脉粥样硬化病变中积累,直接影响斑块巨噬细胞。最后,我们证明了三个月的低剂量他汀-rHDL治疗方案抑制斑块炎症进展,而一周的高剂量治疗方案显着减少晚期动脉粥样硬化斑块的炎症。他汀-rHDL代表了一种新的有效的动脉粥样硬化纳米疗法,直接影响斑块炎症。
Inflammation is a key feature of atherosclerosis and a target for therapy. Statins have potent anti-inflammatory properties but these cannot be fully exploited with oral statin therapy due to low systemic bioavailability. Here we present an injectable reconstituted high-density lipoprotein (rHDL) nanoparticle carrier vehicle that delivers statins to atherosclerotic plaques. We demonstrate the anti-inflammatory effect of statin-rHDL in vitro and show this effect is mediated through inhibition of the mevalonate pathway. We also apply statin-rHDL nanoparticles in vivo in an apolipoprotein E-knockout mouse model of atherosclerosis and show they accumulate in atherosclerotic lesions where they directly affect plaque macrophages. Finally we demonstrate that a three-month low-dose statin-rHDL treatment regimen inhibits plaque inflammation progression, while a one-week high-dose regimen markedly decreases inflammation in advanced atherosclerotic plaques. Statin-rHDL represents a novel potent atherosclerosis nanotherapy that directly affects plaque inflammation.
