| Outline of Final Research Achievements |
In the present study, we assessed possibility of unsaturated fatty acid to treat depression. Polyunsaturated fatty acids and oligodendrocyte have been reported taht were decreased in patients brain of depression. In the present study, we focused on oligodendrocyte and assessed how unsaturated fatty acids affects oligodendrocyte differentiation; we analyzed relationships between red blood cell membrane fatty acids levels and score for depression (Zung Self-rating Depression Scale). Unsaturated fatty acids dose-dependently enhanced oligodendrocyte differentiation from both neural stem cells and oligodendrocyte progenitor cells. Polyunsaturated fatty acids diminished depressive symptoms by assessed forced-swim tests. Decreased Red blood cell membrane mono-unsaturated fatty acids and n-3 polyunsaturated fatty acids were related with SDS scale. These results were indicated that unsaturated fatty acids may prevent and treat depression by affecting oligodendrocyte differentiation.
