We describe herein the effects of Marek's disease herpesvirus (MDV) on cholesterol and cholesteryl ester metabolism in cultured chicken arterial smooth muscle cells. Infection of arterial smooth muscle cells from specific pathogen-free chickens with MDV, but not a virus control, herpesvirus of turkeys led to a 7-10-fold increase in the accumulation of free and esterified cholesterol and a 2-fold increase in phospholipids. The cellular lipid changes observed in the MDV-infected arterial smooth muscle cells resulted, in part, from the following: decreased low-density lipoprotein-cholesteryl ester hydrolysis due to decreased lysosomal (acid) cholesteryl ester hydrolytic activity; increased de novo synthesis of cholesterol; decreased excretion of free cholesterol; and, both increased cholesteryl ester synthetic activity and decreased cytoplasmic (neutral) cholesteryl ester hydrolytic activity which resulted in increased incorporation of oleic acid into cholesteryl ester. Other changes noted in the MDV-infected cells as compared to uninfected cells included a 2-fold increase in both total protein synthesis and lysosomal and microsomal marker enzyme activities. These alterations in lipid and protein metabolism in MDV-infected arterial smooth muscle cells may explain in part our in vivo findings that herpesvirus (MDV) infection of specific pathogen-free chickens fed a normocholesterolemic diet will induce arterial thickening and lipid accumulation resembling human atherosclerosis.
