Cerebral endothelial GABA-T activity: effects of in vivo GABA-T inhibition

Neuroscience Letters
A Krantis


The effects of gamma-aminobutyric acid transaminase (GABA-T) inhibitors on rat endothelial GABA-T activity has been studied utilizing a modified tetrazolium salt histochemical technique. Blue-diformazan staining of cerebrovascular and parenchymal sites of GABA catabolism in normal brain was almost completely prevented in unfixed frozen brain sections from rats subjected to 'in vivo' GABA-T inhibition using aminooxyacetic acid or gabaculine. These results provide histochemical evidence for the efficacy of using systemically administered GABA-T inhibitors to inhibit endothelial GABA-T activity.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
