Outline of Final Research Achievements

It remains unclear how senescent cells escape senolytic immune surveillance to accumulate with age. Lack of adequate animal models makes it difficult to investigate these issues related to accumulation of senescent cells with aging. Therefore, this study is designed to investigate the molecular mechanisms underlying accumulation of senescent cells that contributes to pathological aging by establishing various animal models.

Academic Significance and Societal Importance of the Research Achievements

現在、老化細胞において特異的にアポトーシスを誘導する薬剤(Senolytics)の開発が盛んに行われているが、内因性Senolysisに注目した研究は皆無であり、その分子機序も明らかになっていない。従って、加齢や加齢関連疾患の病態に伴う内因性の老化細胞除去システムの機能低下に関する研究は、極めて独創的である一方探索的なものであるが、その分子機序が明らかとなれば、新たな個体老化の分子機序の一つとなるとともに、新規治療標的となりうる点で、挑戦的研究にふさわしいとものと考えられる。
