Outline of Final Research Achievements |
We investigated the involvement of Nrf2 / ARE signaling pathway and the neuroprotective mechanism of ischemic tolerance phenomenon using rat transient forebrain ischemia model. Following transient forebrain ischemia, expression of Nrf2 was observed in neuronal cells, astrocytes, and microglial cells, and the expression kinetics differed between lethal ischemia and non-lethal ischemia . In the ischemia tolerance model, the expression of Nrf2 tended to be amplified and maintained over a long period of time. It was suggested that the neuroprotective mechanism of the ischemic tolerance phenomenon may involve the activation of the Nrf2 pathway of glial cells in addition to the intrinsic protective mechanism of neuronal cells.
