Outline of Final Research Achievements

The effects of ion or water permeability through epithelial tight junction is not well understood.
In this research, the aim is to clarify the biological functions and it's mechanisms regulated directly or indirectly by the properties of intercellular tight junction in epithelial cells.One of the most interesting biological function is pH dependency, especially dependency of lower pH of basal side culture medium on TER. It suggests there is some special mechanism which works as a sensor residing only in basal side of cells.
