Effect of neonatal DEX treatment on glutamate uptake activity in gliosomes. Summary bar graphs depicting glutamate uptake activity in gliasomes from the frontal cortex of SAL- and DEX-treated groups on P7. DEX-treated group exhibited a significant decrease of total, and GLT-1-mediated glutamate uptake compared with those of SAL-treated group. The non-GLT-1-mediated glutamate uptake was calculated in the presence of GLT-1 inhibitor dihydrokainate (100 μM). The numbers in parentheses indicate the number of animals examined. Data are presented as means ± S.E.M. *P < 0.05 compared with SAL-treated group.
