Outline of Final Research Achievements

The surface of our body is covered by the cellular sheet which is designated the epithelium. Epithelial cells are arranged like cobblestones and adhere with each other, thereby the leak of water-soluble substances through the intercellular space is restricted. In this study, we investigated the function of angulin family proteins constituting tricellular contacts, where the vertices of three epithelial cells meet. The mice lacking one of the angulin family proteins showed healing loss caused by the degeneration of hair cells in the inner ear.
