Adenosine transport by rat and guinea pig synaptosomes: basis for differential sensitivity to transport inhibitors.

abstract：:GABA(A) receptors are the major inhibitory neurotransmitter receptors in the brain. Some of them are targets of benzodiazepines that are widely used in clinical practice for their sedative/hypnotic, anxiolytic, muscle relaxant and anticonvulsant effects. In order to rationally separate these different drug actions, we...
