title: In vitro studies of guanidinoethyl sulfonate and taurine transport in the rat retina.
abstract: The present study reports inhibition of taurine uptake in the rat retina in vitro to 49% of control by 1 mM guanidinoethyl sulfonate. No efflux of preloaded [14C]taurine was observed by incubation in the presence of guanidinoethyl sulfonate. The in vivo depletion of retinal taurine by guanidinoethyl sulfonate treatment may arise owing to antagonism of taurine transport into the retina from the blood.
