Outline of Research at the Start

インスリン産生膵β細胞の再生による新たな糖尿病治療戦略を考えた場合、膵島内の隣接する非β細胞からβ細胞への分化転換(ダイレクトリプログラミング)戦略は解剖学的・発生学的さらには機能的見地からも大変有望なアプローチである。最近、代表者はヒト脳死ドナー膵島を用いてこの分化転換を報告した(Nature, 2019)が、本研究では、低分子化合物を使った分化転換誘導を目指し、実現可能な次世代型糖尿病治療につながる基盤研究を行う。

Outline of Final Research Achievements

Previously we have shown that non-β-cells from islets of cadaveric donors can convert into insulin producing cells, providing a proof of concept for clinical applications. Our ultimate goal was to develop the transdifferentiation therapy as a future-oriented therapeutic strategy for diabetes. Here we improved the transdifferentiation, quantitatively and qualitatively, and elucidated its underlying mechanisms, enabling us to establish the foundation for future development of transdifferentiation therapy for diabetes.

Academic Significance and Societal Importance of the Research Achievements

インスリン分泌β細胞の再生による糖尿病治療を目指した場合、膵島内の隣接するnon-β細胞からβ細胞への分化転換 (ダイレクトリプログラミング) を誘導する戦略は解剖学的・発生学的さらには機能的見地からも大変有望なアプローチである。つまり、β細胞を膵島内に存在する近隣の他細胞から分化転換誘導するので、作製した細胞を移植する必要が無く、その再生した細胞は元来の膵島内細胞環境で機能を発揮しやすいことから、糖尿病に対する未来型再生治療戦略と言える。
未来の臨床現場では、本研究の分化転換療法を含め、多角的なアプローチを組み合わせることで、個別化された糖尿病治療戦略が患者さんに必要だと考えている。
