摘要

The present study aimed to investigate the involvement of the NMDA receptor (NMDAR) and/or nitric oxide (NO) pathway in ketamine-induced behavioral sensitization. Mice received repeated subcutaneous administration of ketamine (25 mg/kg), once daily or once weekly for a total of five doses. Even three administrations of ketamine, daily or weekly, induced a rapid increase in locomotor activity in wildtype (WT), but not in GluN2D knockout (GluN2D-KO) mice. Furthermore, for WT mice receiving daily ketamine, elevated locomotor activity was maintained after a 1-month withdrawal period; however, this was not the case when ketamine was administered weekly.
