Abstract:Dietary supplementation with n-3 polyunsaturated fatty acids (n-3 PUFA) reduces amyloid-β (Aβ) and tau pathology and improves cognitive performance in animal models of Alzheimer's disease (AD). To exclude confounding variables associated with the diet, we crossed 3 × Tg-AD mice (modeling AD neuropathology) with transgenic Fat-1 mice that express the fat-1 gene encoding a PUFA desaturase, which endogenously produces n-3 PUFA from n-6 PUFA. The expression of fat-1 shifted the n-3:n-6 PUFA ratio upward in the bra…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
