Rapid down-regulation of GABAA receptors in the gerbil hippocampus following transient cerebral ischemia.

Abstract

During transient cerebral ischemia, there is a temporary and robust accumulation of extracellular GABA in the hippocampus. We examined whether the acute exposure of GABAA/benzodiazepine receptors to high concentrations of GABA early after ischemia results in receptor down-regulation as observed in vitro. Gerbils were killed 30 and 60 min following a 5-min… (More)
