| Research Abstract |
We investigated the activation mechanism of one of the most influential regulators of cell volume, shape and fate, the volume-sensitive outwardly rectifying (VSOR) anion channel in the central nervous system. Within this research period, we have found especially a fundamental mechanism of VSOR channel activation in the major glial cells, astrocytes, which would operate even in response to a minute damage happening in surrounding tissues with high fidelity and certainty.
