| Outline of Final Research Achievements |
By administering CLP290, intracellular chloride ion is pumped out of the cell and the extracellular chloride ion concentration becomes relatively high. In the present study, it was found that CLP290 increases phosphorylation of KCC2, which regulates intracellular chloride ion concentration. When a GABA receptor agonist is administered in this state, chloride ions are introduced into the cells from outside the cell, which has a high concentration, following activation of the GABA receptor, and nerve cell activation is suppressed. In this study, this phenomenon was clarified by immunohistological examination using pCREB. It was revealed that these cell biological changes cause sedation at the individual level. In this study, we investigated this phenomenon using the direct reflection.
