| Research Abstract |
In this study, we examined the effects of dietary supplementation with polyunsaturated fatty acid (arachidonic acid or docosahexaenoic acid) on Alzheimer's disease pathology. Polyunsaturated fatty acid diet prevents memory impairment in Alzheimer model Tg2576 mice. APP processing to generate soluble APP and Aβ synthesis were enhanced, but the Aβ1-42/Aβ1-40 ratio was decreased in Tg2576 mice fed with the arachidonic acid or docosahexaenoic acid diet. These findings suggest that polyunsaturated fatty acid diet could prevent cognitive dysfunction, and alter APP processing and Aβ1-42/Aβ1-40 ratio in Tg2576 mice.
