[Improving of HDL capacity for macrophages cholesterol efflux after plasma incubation with phospholipid nanoparticles].

In connection with recent data about antiatherogenic importance of not only plasma HDL concentration, but of their cell cholesterol efflux capacity as well, the possibility of its correction by phospholipid (PL) nanoparticles was studied. Blood plasma was incubated with earlier elaborated PL nanoparticles emulsion with the particle diameter up to 30 nm, and HDL cholesterol efflux capacity of apo B-depleted plasma was studied. Using macrophages THP-1 preloaded 3H-cholesterol were used.
