| Research Abstract |
First, we investigated glucose metabolism in astroglia during hypoxia. Hypoxia without glucoprivation induced pentose phosphate pathway(PPP) activation in astroglia. PPP activation by hypoxia was accompanied by Nrf2 translocation to the nucleus but not by Bip expression in the ER. Next, we investigated the effects of secretory leukoprotease inhibitor(SLPI) on the cell damage during ischemic-reperfusion injury. Alamar Blue reduction increased by SLPI during oxygen glucose deprivation in neurons, while SLPI did not affect astroglial cell viability. The effects of SLPI in cerebral ischemia might be different between astrocytes and neurons.
