Outline of Research at the Start

組織構成細胞が増殖、遊走移動、分化、幹細胞維持を制御し器官形成は進行する。唾液腺を含めた上皮系器官の発生は、上皮が間葉組織に侵入し器官形成が進行するが、上皮より神経組織の陥入が先行し、神経伝達物質を介して上皮細胞の細胞遊走が誘導され、間葉組織内に陥入していくことが明らかとなっている。本研究では神経伝達物質を介した上皮細胞の分化と増殖、さらには効果器となる細胞の組織内マッピングの制御機構におけるエピプロフィンの役割を解明し、神経ー効果器ユニットを有した画期的な器官再生法樹立を目指す。

Outline of Final Research Achievements

In this study, we elucidated the function of the transcription factor Epiprofin (Epfn) in the development and post-irradiation repair of salivary glands and identified a novel interacting factor, X. Epfn is expressed in ductal epithelial cells of the salivary glands, and Epfn-deficient mice exhibited morphological abnormalities, indicating its essential role in glandular development. Moreover, we found that factor X is upregulated following irradiation and is associated with Epfn and the Notch signaling pathway, suggesting a potential mechanism underlying salivary gland repair. These findings advance our understanding of the molecular basis of neuro-epithelial interactions during organogenesis and regeneration of the salivary glands, and provide a foundation for developing regenerative therapies aimed at restoring gland function after radiation-induced damage.

Academic Significance and Societal Importance of the Research Achievements

癌治療には、手術療法、薬物療法、放射線療法があり、これらの治療を効果的に組み合わせることは、予後と癌治療後のQOLの向上に直結する。唾液腺細胞は放射線感受性が高く、顎下腺組織が体の表面近くに位置していることもあり放射線治療では照射後に唾液分泌能力が低下してしまうことがある。唾液分泌低下は、口腔衛生、摂食、咀嚼、発音、呼吸、睡眠に対して悪影響を及ぼしQOLの低下を招く。本研究では、唾液腺の正常発生時に発現している因子を応用した唾液分泌能力の賦活、神経と唾液腺上皮の再構築を目指しているため、放射線障害、口腔乾燥症、嚥下障害の新規治療法の開発にもつながり、国民の健康と福祉の向上に貢献する。
