Decreased Susceptibility to Diet-Induced Atherosclerosis in Human Apolipoprotein A-II Transgenic Mice

Studies performed in vivo have been controversial regarding the implication of human apolipoprotein (apo)A-II in the atherogenic process. Expression of human apoA-II in transgenic mice fed a chow diet leads to (1) a bimodal distribution of high density lipoprotein (HDL) size as in humans, (2) a reduction in total cholesterol concentration that is mainly due to a reduction in non-HDL cholesterol level, and (3) a dramatic reduction in mouse...
