Outline of Final Research Achievements

Cell competition is a novel type of cell-cell interaction that selectively eliminates ‘unfit’ cells from the tissue. For instance, unfit mutant cells are viable by themselves but are eliminated by cell competition when surrounded by wild-type cells. Previously, we found that autophagy-dependent cell death is induced in unfit “loser” cells nearby wild-type “winner” cells, while the upstream mechanism of autophagy is unclear. In this study, we dissected the mechanism by which autophagy is upregulated during cell competition.

Academic Significance and Societal Importance of the Research Achievements

今回見いだした細胞非自律的オートファジーによるメカニズムは、種々のトリガーによって引き起こされる細胞競合を共通して制御することがわかり、細胞競合を介した腫瘍制御にも重要な役割を果たすこともわかった。今後、このオートファジー誘導機構を完全解明することで細胞競合の全貌が明らかになり、細胞間コミュニケーションの新たなコンセプトが確立されるとともに、これを人為的に制御することで新たながん治療やアンチエイジングに貢献できる可能性がある。
