Abstract

Treatment for 11-13 weeks with a cholesterol-rich diet induced increases in free and esterified serum cholesterol. There was also an increase in free cholesterol of peritoneal macrophages. A 2.2 times rise in the cholesterol to phospholipid ratio of plasma membranes occurred in cholesterol-enriched macrophages. No changes were observed in phagolysosomes. Cholesterol-enriched macrophages showed a 35.8% inhibition of latex particles phagocytosis. When lipid droplets were substituted for latex the inhibition was 81.7%.
