Regulation of the threshold for lipoprotein-induced acyl-CoA:cholesterol O-acyltransferase stimulation in macrophages by cellular sphingomyelin content.
Macrophage acyl-CoA:cholesterol O-acyltransferase (ACAT), a key enzyme in atheroma foam cell formation, is stimulated by lipoproteins only after a “threshold” amount of cholesterol has accumulated in the cell. The present study explores the hypothesis that cellular sphingomyelin, by increasing the c...
