Outline of Final Research Achievements |
Aiming to establish a novel treatment strategy for treatment-resistant depression, we conducted a study using refractory depression model rats that we had created ourselves. From the perspective of reward prediction, we focused on social interaction and empathic functions, as it is considered that the inability to moderately over-predict reward is linked to impaired motivation and execution of prosocial behavior. Based on our previous studies, we examined the effectiveness of a regenerative medicine approach using 'drug + cell' treatment, and found that the usefulness of the combined administration of drugs acting as oxytocinergic neuron activators and bone marrow-derived mesenchymal stem cell.

Academic Significance and Societal Importance of the Research Achievements |
標準的な抗うつ薬治療では回復しないうつ病への対応が臨床現場では大きな問題となっており、遷延化・難治化するうつ病に対する有用な治療法の確立は喫緊の課題である。難治性うつ病モデルを用いた本研究により、一般的な抗うつ薬以外の薬物と骨髄間葉系幹細胞併用処置による再生医療的アプローチの有効性と、新たな治療ターゲット分子候補が示唆された。難治性うつ病の病態理解および新規治療戦略確立の上での学術的意義および社会的意義は大きい。
