Efavirenz as a potential anti-Alzheimer's disease medication

E

favirenz is the anti-HIV medication given daily at a 600 mg dose to keep the viral

load low. We found that in mice, a very low dose of efavirenz (100-times lower than

that given to HIV patients) enhances the activity of the brain enzyme cytochrome P450

46A1 (CYP46A1), which converts cholesterol to 24-hydroxycholesterol. Cholesterol

24-hydroxylation is the major pathway of cholesterol elimination from the brain;

CYP46A1 controls this pathway and thereby cholesterol turnover in the brain. 5XFAD

mice, a model of rapid amyloidogenesis, were treated daily with a 0.1 mg/kg of body

weight efavirenz dose, which was delivered in drinking water. The treatment started at one

month of age and continued for eight months. Efavirenz administration stably activated

CYP46A1 and enhanced cholesterol turnover in the 5XFAD brain. 5XFAD mice also had

a significant reduction in amyloid-b burden and microglia activation in the brain cortex

and hippocampus. Mouse performance was improved in Morris water maze test, and the

treated animals had a significant reduction in mortality rates. The data obtained suggest

that efavirenz should be considered as an anti-Alzheimer's disease medication, and the

pathway of the brain cholesterol removal as a therapeutic target for this disease. A clinical

trial is in progress to evaluate efavirenz effects on people with mild cognitive impairment

due to Alzheimer's disease.
