Outline of Research at the Start

我々は組織再生の過程で起こる細胞老化に着目し、細胞老化を正常化する事で不要な細胞を除去し、慢性炎症で変性した組織を再生できることを発見した。ついで、運動刺激による筋間質細胞の老化誘導が筋再生に不可欠であること、一方で筋実質細胞の老化は再生を阻害することを見出した。これら一連の研究成果から、細胞への力学ストレスによって細胞老化を正常化して組織再生を導く、“セノリハビリテーション”(seno = 老化)の可能性を見出した。本研究では、リハビリテーションによる細胞老化制御メカニズムを解明することで、セノリハビリテーションという細胞・分子レベルから細胞老化を制御する新たな治療基盤の創成を目指す。

Outline of Final Research Achievements

Senescent cells secrete various bioactive factors, such as cytokines and growth factors, which influence surrounding cells to promote tissue regeneration. Our previous research has suggested that mechanical stimulation can modulate cellular senescence, leading to the concept of "Senorehabilitation." This approach aims to control cellular senescence through rehabilitation to enhance tissue regeneration, and its potential has been investigated.

In this study, we identified cell populations that are more prone to senescence induction through in vitro experiments and single-cell RNA-seq analysis of mouse skeletal muscle post-exercise. Additionally, we discovered that different cell populations are more susceptible to senescence induction in the skeletal muscle of obese mice following exercise.

Academic Significance and Societal Importance of the Research Achievements

細胞老化はサイトカインや成長因子など様々な生理活性因子を分泌することで周囲の細胞に働きかけて組織を再生へ導く一方、長期的に組織に蓄積することで慢性炎症を引き起こす原因細胞となる。この老化細胞を標的とした治療法の開発が、慢性炎症疾患および健康長寿達成のために大きな注目を集めている。本研究成果では、運動刺激によって細胞老化が誘導されやすい細胞集団を同定に成功した。この成果は、メカニカルストレスおよびリハビリテーションによる細胞老化制御の達成に向けた基盤データとなり、将来的には健康長寿社会達成につながる可能性を有している。
