Outline of Final Research Achievements

Abnormalities in autophagy have been shown to be involved in the pathogenesis of a variety of diseases. We have found that Vsp34 (a class III PI3-kinase)-deficient mouse epidermis developed lesions similar to those in psoriasis vulgaris. In psoriasis, the epidermis is abnormally thickened, suggesting a relationship with stem cells. As part of our stem cell research,we have also found that the transcription factor Sox13 could serve as a novel marker for hair follicle stem cells.

Academic Significance and Societal Importance of the Research Achievements

食事の西洋化に伴い、わが国では尋常性乾癬の患者が増加し、メタボリック症候群との関連も注目されている。本研究で私たちが作製した、表皮特異的なVsp34欠損を基盤とする新しい乾癬モデルは、乾癬発症におけるオートファジーの役割の解明につながる可能性がある。また、Sox13は、新しい毛包幹細胞マーカーとして、幹細胞研究の発展に寄与すると考えられる。
