Abstract

The effect of aging on the binding of ligands to the GABA, benzodiazepine and picrotoxin binding sites as well as α subunit mRNA level of GABA_A receptor was investigated in cerebral cortex of male Fischer F-344 rats. In aged (730- to 770-day-old) rats, the binding of [³⁵S]t-butylbicyclophosphorothionate (TBPS) was significantly reduced. Also, α₁ mRNA level was markedly decreased (86% suppression). In contrast, α₁ mRNA remained unchanged in cerebellum. These findings indicate a selective age-related structural change in GABA_A receptor in rat cerebral cortex.
