Apolipoprotein M is required for pre|[beta]|-HDL formation and cholesterol efflux to HDL and protects against atherosclerosis

Christian Wolfrum , Matthew N Poy & Markus Stoffel

High-density lipoproteins (HDLs) are considered antiatherogenic because they mediate reverse cholesterol transport from the periphery to the liver for excretion and degradation. Here we show that mice deficient in apolipoprotein M (apoM), a component of the HDL particle, accumulated cholesterol in large HDL particles (HDL1) while the conversion of HDL to preβ-HDL was impaired.
