Cyclic AMP-regulated GABA release at inhibitory synapses in rat cerebellar slices

J Physiol Paris. 1996;90(5-6):327-8. doi: 10.1016/s0928-4257(97)87909-0.

Abstract

We have investigated the effects of agents interfering with the cAMP pathway on the rate of miniature IPSCs in cerebellar slices. Noradrenaline and group II glutamate metabotropic receptor agonists respectively enhance and reduce the rate of miniature IPSCs, presumably because they respectively increase and decrease the presynaptic concentration of cAMP.
