Outline of Final Research Achievements |
Podocytes, located in the glomeruli of the kidney, are essential for blood filtration. These cells extend foot processes from primary processes, interdigitating with neighboring cells to form a slit diaphragm, which is crucial for filtration. The unique morphology of podocytes is fundamental to their function. In this study, we investigated the localization of motor proteins highly expressed in podocytes and conducted a detailed functional analysis of Myo10. Myo10 exhibited low expression during the early stages of podocyte development but increased expression in mature podocytes. Overexpression of Myo10 resulted in promoted and complex processses in podocyte cell lines. These findings suggest that Myo10 plays a critical role in the morphogenesis and maintenance of podocytes.

Academic Significance and Societal Importance of the Research Achievements |
ポドサイトはその特殊な形態が濾過機能に重要である事が知られている。ポドサイトは高血圧や高血糖などの過度なストレスに曝されると足突起は消失し、濾過機能を失う。さらにストレスが続くと糸球体より脱落してしまう。ポドサイトは高度に分化した細胞で増殖能が無いため残った細胞がその埋め合わせをすることになりさらに細胞にストレスがかかり悪循環に繋がる。そのためポドサイトの形態の形成と維持は腎臓の濾過機能を保つために非常に重要な機構である。本研究はMyo10が形態形成の促進を担っていることが分かり、慢性腎臓病の予防や回復の礎になることが期待される。
