| Research Abstract |
We have developed a imaging method with several fluorescent proteins, I successfully observed the intracellular dynamics of Kir channels in living cells. I provided the evidences that Kir subtypes that compose the channel dramatically determine the intracellular dynamics. This mechanism may underlie the position control of Kir channels. In this study, we also examined the direct effect of drugs that clinically used in the treatments for neural disorders on Kir channel function, we found that several drugs, such as a series of antidepressants or antipsychotics, inhibit glial Kir channel (Kir4.1 channel) function by binding with the central cavity of it's pore.
