| Outline of Final Research Achievements |
Intake of n-3 fatty acid deficient diet and deficiency of FABP7 (brain-type fatty acid binding protein), which has high affinity for n-3 fatty acids, may affect weight gain, peripheral immune cell number and differentiation. FABP7 deficiency suppressed food intake and obesity when a high-fat diet was consumed. FABP7 has also been shown to play a role in regulating inflammation and protecting cell death. Another polyunsaturated fatty acid regulator has also been shown to control the exacerbation of inflammatory bowel disease.

| Academic Significance and Societal Importance of the Research Achievements |
多価不飽和脂肪酸が肥満や炎症に与える影響について、これまで栄養学的な知見によって確認されてきた事項を、動物モデルや細胞学的なデータから解析し、その機序の一旦を示すことができた。定常状態の解析結果については疾患の予防、炎症時の解析結果については疾患の機序の解明や新しい治療の開発に繋げることができると考えられる。
