Popis: The treatment of atherosclerosis remains complex. Pitavastatin serves an important role in the prevention and treatment of atherosclerosis. The present study aimed to investigate the effects of nanoparticle (NP)-mediated delivery of pitavastatin into atherosclerotic plaques as a novel treatment method for atherosclerosis. The results of the present study demonstrated that pitavastatin-NP was more effective in attenuating the size of atherosclerotic plaques and enhancing the stability of plaques in vitro compared with pitavastatin alone. In an apolipoprotein E (ApoE)-knockout mouse model of atherosclerosis, a single intravenous injection of fluorescein isothiocyanate-NP resulted in the delivery of NP into atherosclerotic plaques for up to 7 days post-injection. In ApoE-knockout mice and THP-1-derived macrophages, pitavastatin-NP attenuated the development of atherosclerosis, which was associated with regulating lipid metabolism, and inhibited the secretion of inflammatory markers compared with pitavastatin alone. Additionally, the treatment advantages of pitavastatin-NP were independent of lipid lowering. The results demonstrated that pitavastatin-NP administration was more effective in attenuating the development of atherosclerotic plaques compared with systemic administration of pitavastatin.
