ABSTRACT
It was previously reported by Tabas et al. that J774 macrophages, unlike mouse peritoneal macrophages, accumulate large amounts of cholesteryl esters when incubated with native low-density lipoprotein (LDL). Comparison of the cell line (designated J774A.2) used in those experiments with its parent line (J774A.1) indicates that it is a variant with a greater rate of cholesterol esterification. This large difference in cholesterol esterification was accompanied by only a small difference in rates of LDL uptake and degradation by the J774A.2 line. The J774A.2 cells have become a variant line through either mutation or selection which has enhanced its susceptibility to foam cell formation by its markedly increased ability to esterify cholesterol.
