The vast majority of Alzheimer's disease (AD) cases are late-onset and their development is
probably influenced by both genetic and environmental risk factors. A strong genetic risk
factor for late-onset AD is the presence of the ɛ4 allele of the apolipoprotein E (APOE) gene,
which encodes a protein with crucial roles in cholesterol metabolism. There is mounting

Abstract
The vast majority of Alzheimer's disease (AD) cases are late-onset and their development is probably influenced by both genetic and environmental risk factors. A strong genetic risk factor for late-onset AD is the presence of the ɛ4 allele of the apolipoprotein E (APOE) gene, which encodes a protein with crucial roles in cholesterol metabolism. There is mounting evidence that APOE4 contributes to AD pathogenesis by modulating the metabolism and aggregation of amyloid-β peptide and by directly regulating brain lipid metabolism and synaptic functions through APOE receptors. Emerging knowledge of the contribution of APOE to the pathophysiology of AD presents new opportunities for AD therapy.
