Title
(EN) NANOPARTICLES FOR LIPID HOMEOSTASIS
Abstract
(EN)

Nanoparticles include a polymeric core and a high density lipoprotein (HDL) component where the ratio by weight of the HDL component to the polymeric core is in a range from about 1:9 to about 9:1, such as about 75:25 or less or about 7:3 or less. The nanoparticles may also include a mitochondria targeting moiety. The nanoparticles may be used to treat or prevent atherosclerosis or to maintain lipid homeostasis.
