Nutrients, Vol. 9, Pages 1122: Resveratrol and Amyloid-Beta: Mechanistic Insights (Nutrients)

The amyloid-beta (A?) hypothesis that dyshomeostasis between A? production and clearance is a very early, key molecular factor in the etiology of Alzheimer`s disease (AD) has been proposed and examined in the AD research field. Scientists have focused on seeking natural products or drugs to influence the dynamic equilibrium of A?, targeting production and clearance of A?. There is emerging evidence that resveratrol (Res), a naturally occurring polyphenol mainly found in grapes and red wine, acts on AD in numerous in vivo and in vitro models. Res decreases the amyloidogenic cleavage of the amyloid precursor protein (APP), enhances clearance of amyloid beta-peptides, and reduces A? aggregation. Moreover, Res also protects neuronal functions through its antioxidant properties. This review discusses the action of Res on A? production, clearance and aggregation and multiple potential mechanisms, providing evidence of the useful of Res for AD treatment.
