摘要
The intake of the polyunsaturated fatty acid docosahexaenoic acid (DHA) or n-3 fatty acid has been associated with reduced risk of Alzheimer's disease (AD) in epidemiological reports. However, the underlying mechanism remains to be elucidated. Here, we report that exogenous DHA administration could protect neurons against A beta oligomer-induced injury both in vitro and in vivo, partly through reducing the endoplasmic reticulum (ER) stress, and preventing cell apoptosis. In transgenic fat-1 mice with enriched omega-3 fatty acids, A beta oligomers induced fewer neuronal losses, when compared to wild-type (WT) mice. We conclude that endogenous DHA are neuroprotective in pathogenesis processes of AD.
