Outline of Final Research Achievements |
In this study, we found that haloperidol, a typical APD and risperidone, an atypical APD differentially modulated cortical Kv3.1 and Kv3.2 channels. While both haloperidol and risperidone significantly increased Kv3.1 protein levels in rat prefrontal cortex, Kv3.2 protein levels showed an increase and a decrease in the same region by haloperidol and risperidone, respectively. A similar pattern of Kv3.2 change was found in cerebellum, however, no significant changes were found in Kv3.2 protein levels in hippocampus, thalamus and striatum. These result were reported in Annual Meeting of the Japanese Society of Psychiatry and Neurology.
