Proline promotes decrease in glutamate uptake in slices of cerebral cortex and hippocampus of rats.

In the present study we first investigated the in vitro and in vivo effects of proline on glutamate uptake in the cerebral cortex and hippocampus slices of rats. The action of alpha-tocopherol and/or ascorbic acid on the effects elicited by administration of proline was also evaluated. For in vitro studies, proline (30.
