Resveratrol Promotes Clearance of Alzheimer's Disease Amyloid-β Peptides

Several epidemiological studies indicate that moderate consumption of wine is associated with a lower incidence of Alzheimer's disease. Wine is enriched in antioxidant compounds with potential neuroprotective activities. However, the exact molecular mechanisms involved in the beneficial effects of wine intake on the neurodegenerative process in Alzheimer's disease brain remain to be clearly defined. Here we show that resveratrol (trans-3,4′,5-trihydroxystilbene), a naturally occurring polyphenol mainly found in grapes and red wine, markedly lowers the levels of secreted and intracellular amyloid-β (Aβ) peptides produced from different cell lines. Resveratrol does not inhibit Aβ production, because it has no…
