Neuropharmacology And NeurotoxicologyDifferential effects of lovastatin treatment on brain cholesterol levels in normal and ApoE-deficient miceEckert, Gunter P.; Kirsch, Christopher; Mueller, Walter E.CAAuthor Information Department of Pharmacology, Biocenter Niederursel, University of Frankfurt, Marie-Curie-Str. 9, D-60439 Frankfurt, Germany CACorresponding Author Received 8 December 2000; accepted 18 January 2001 NeuroReport: April 17th, 2001 - Volume 12 - Issue 5 - p 883-887 Buy Abstract Growing evidence indicates that membrane cholesterol is involved in the development of Alzheimer's disease. Therefore, the availability of pharmacological strategies to modify brain cholesterol is of increasing importance. Accordingly, we investigated the effects of the HMG-CoA reductase inhibitor lovastatin on brain cholesterol levels in vivo. Brain cholesterol was significantly decreased by lovastatin treatment (100 mg/kg/day) in 1- and 12-month-old C57BL/6J mice. Reduced brain cholesterol was associated with decreased pyrene-excimer fluorescence, indicating altered membrane function. Lovastatin had no effect on brain cholesterol in ApoE−/− mice. Peripheral cholesterol levels were not affected by lovastatin in all three groups of mice. We demonstrate for the first time that lovastatin represents a valid pharmacological tool to significantly modulate brain cholesterol levels. © 2001 Lippincott Williams & Wilkins, Inc.
