Use of transgenic mice to study the role of apolipoprotein E in lipid metabolism and atherosclerosis.
Insight into the role of apolipoprotein (apo) E in lipoprotein metabolism and atherosclerosis has increased dramatically with the generation and analysis of novel transgenic, knockout and knockin mouse models. Moreover, the recent development and application of somatic gene and cell transfer technologies which can express (or delete) apoE in specific tissues of virtually any mouse model have further added to this increase in knowledge. It is now well established that apoE plays a role in virtually every step in the metabolism of very low-density lipoproteins and in the efflux of cholesterol from macrophages. In this review we will discuss recent insights into the role of apoE in these processes with particular emphasis on the specific effects of variation in apoE structure and quantity.
