Description
Summary:Cardiovascular disease remains the dominant contributor to human mortality, and the main etiology of which is atherosclerosis (AS). Enhancing the targeted ability of nanosystem and improving plaque stability are critical challenges for the current management of AS. Herein, we leverage the marked role of platelets in AS to construct a biomimetic nanodrug delivery system (PM@Se/Rb1 NPs), which prepared by cloaking platelet membrane (PM) around Selenium (Se) and ginsenoside Rb1 nanoparticles (Se/Rb1 NPs) core. The core endows the delivery system antioxidant, lipid metabolism and anti-inflammatory effects for AS effective treatment. Moreover, PM-coated nanoparticles reserve platelets’ inherent biological elements to deliver drugs to plaques. We further explored the potential effect of PM@Se/Rb1 NPs’ combination with the clinical anticoagulant drug warfarin (War) to treat AS and elucidated the possible drug interaction mechanism. As a result, the PM@Se/Rb1 NPs are not only capable of improving inflammatory behaviors such as inhibitory adhesion ability and anti-angiogenesis therapeutic effect in vitro, but also administer efficiently localizing to atherosclerotic plaque explaining by aortic samples from established ApoE-/- mice. Therefore, this study provided a theoretical basis of biomimetic nanodrug in the treatment of AS as well as an effective reference for the combined application of nanodrug and clinical drugs.
