The light-stimulated release of [3H]taurine from chick retina was studied in chicks intraocularly injected with kainic acid (60 nmol). This treatment produced a loss of more than 80% of the inner nuclear and the inner synaptic layers, sparing the outer retinal layers. Concomitantly, the treatment produced a marked decrease of endogenous GABA and glycine but not of taurine. The activity of glutamate decarboxylase was also markedly decreased in the kainic acid-treated retinas. The release of [3H]taurine, either spontaneous or stimulated by light, was unaffected by the treatment. These results suggest that the light-stimulated efflux of taurine occurs from the retinal layers which are not affected by the kainic acid treatment.
