The electrophysiological features of isolated baboon Müller cells was investigated using the whole-cell voltage-clamp technique. Application of depolarizing voltage steps evoked transient inward and delayed outward currents. The transient currents disappeared when extracellular Na+ was replaced by choline+ and were substantially decreased by application of tetrodotoxin (1 microM). The outward currents were strongly diminished by extracellular Ba2+ (1 mM), and the hyperpolarization-generated inward currents disappeared following application of Ba2+. The recently described gamma-aminobutyric acid A (GABAA) receptor currents were increased by flunitrazepam, nordiazepam, pentobarbital and Zn2+, as well as by the inverse agonist DMCM. These results suggest that the baboon Müller cells possess the same voltage-dependent current pattern as those from other species, e.g. humans, whereas their GABAA receptors react in an uncharacteristic manner to DMCM and Zn2+, when compared with neuronal GABAA receptors.
