title: Studies on the depression of gamma-aminobutyric acid potentials by phloridzin in cat dorsal root ganglion cells in vitro.
abstract: Phloridzin has been used as a tool to investigate membrane transport mechanisms. We have demonstrated that phloridzin acts to depress chloride flux resulting from activation of a gamma-aminobutyric acidA (GABAA) receptor on cat dorsal root ganglion cells. This action appears not to involve an inwardly directed chloride pump postulated for these neurons but rather affects a site associated with the GABA receptor-chloride complex.
