Abstract

Oxidative modification of low-density lipoprotein (LDL) enhances its uptake by macrophages in tissue culture and in vivo may underly the formation of arterial fatty streaks, the progenitors of atheroma. We investigated the possible protection which high-density lipoprotein (HDL) affords against LDL oxidation. The formation of lipoperoxides and thiobarbituric acid reactive substances when LDL was incubated with copper ions was significantly decreased by HDL. The enzyme, paraoxonase (E.C. 3.1.8.1), purified from human HDL, had a similar effect and thus may be the component of HDL responsible for decreasing the accumulation of lipid peroxidation products.
