Application

(±)-AMPA has been used:
  • in vivo

  • whole-cell patch-clamp recording in Müller glial cells
  • to test its excitotoxic effects in hippocampal slice cultures
  • in retinal horizontal cells (HCs) culture to test its effect on Ca2+ signals

Biochem/physiol Actions

Potent excitatory amino acid that interacts selectively with central AMPA/kainate receptors.

Presynaptic inhibition onto axons regulates neuronal output, but how such inhibitory synapses develop and are maintained in vivo remains unclear. Axon terminals of glutamatergic retinal rod bipolar cells (RBCs) receive GABAA and GABAC receptor-mediated synaptic inhibition. We found that perturbing GABAergic
