Outline of Final Research Achievements

We investigated pathophysiology of major depression based on the model of diabetes mellitus (DM). We examine the association between the metabolites of kynurenine pathway and the three major network of major depression (salience network, central executive network, and default mode network). The positive correlation was found the serum Kyn level and salience network in major depression. We also compared in serum levels of IGF1, IL6, hsCRP, TNFα, VEGF, BDNF between MD patients with DM, and MD patients without DM. Serum TNFα was significantly higher in MD patients with DM that those without DM. The response rate and remission rate to antidepressants 8 weeks after starting the antidepressants did not differ between the both groups.

Academic Significance and Societal Importance of the Research Achievements

うつ病患者ではKyn経路の異常があり、それらは脳内ネットワークと密接な関連があることが明らかになった。特にうつ病におけるKyn濃度の異常は脳内salience networkに異常をもたらす可能性がある。さらにDM合併の有無で血漿サイトカイン濃度に差があることがあり、特にTNFαがDMうつ病群では高値であった。我々のこれらの研究結果は以下の意義があると考えられる。1)Kyn経路に関与する分子を標的とした薬物がうつ状態やsalience networkを改善することでうつ病に伴う認知機能も改善する可能性があること。2)DMうつ病ではTNFαを標的とし濃度を低下させる薬物が有効であるかもしれない。
