Studies on role of cholesterol in the pathogenesis of prion disorders

Our findings highlight the existence of metabolic lipid alterations associated with prion infection. A higher content of cholesterol esters (CE) was accompanied by variations in the expression of ACAT-1 and Cav-1 in skin fibroblasts from scrapie-susceptible sheep. Increased levels and altered distribution of free cholesterol (FC), triglycerides, phospholipids and CEs were found in prion-infected N2a cells (ScN2a). Similar cholesterol alterations were observed in brains of Pravastatin-treated and untreated scrapie-infected mice: a high level of cholesteryl-arachidonate was associated with increased CEs in the brain while oral pravastatin administration caused a significant reduction of FC and an additional increase of CEs. In addition, the treatment with dual-drug combinations of a cholesterol ester modulator with a prion inhibitor had showed a synergistic anti-prion effect in ScN2a cells. These data support our hypothesis that certain pathways of cholesterol/cholesterol ester metabolism may represent suitable targets for prion disease therapy.
