Potassium modulation of taurine transport across the frog retinal pigment epithelium
Net taurine transport across the frog retinal pigment epithelium-choroid was measured as a function of extracellular potassium concentration, [K+]o. The net rate of retina-to-choroid transport increased monotonically as [K+]o increased from 0.2 mM to 2 mM on the apical (neural retinal) side of the tissue. No further increase was observed when [k+]o was elevated to 5 mM. The [K+]o changes that m...

(the concentration used for radioautography), the uptake was mainly into the inner retina. However, as the exogenous taurine concentration was decreased to > 1 p~ the percentage of label accumulated by the photoreceptor layer increased with respect to the total uptake (Table 1). Further studies were carried out with the use of lOmin incubations and exposing the retinas to exogenous taurine conc...
متن کاملTaurine uptake in apical membrane vesicles from the bovine retinal pigment epithelium.
Characteristics of taurine uptake were investigated in apical membrane vesicles isolated from bovine retinal pigment epithelium. Uptake of taurine into these vesicles was stimulated markedly by the presence of an inwardly directed NaCl gradient across the membrane. The time course of the NaCl gradient-dependent uptake showed an overshoot, indicating a transient accumulation of taurine in the ve...
متن کاملMorphological changes in injured retinal pigment epithelium and photoreceptor cells after transplantation of stem cells into subretinal space
Introduction: Degenerative retinal diseases are main cause of irreversible blindness. Stem cells therapy is a promising way in these diseases. Therefore, mesenchymal stem cells because of its safety can produce degenerated cells and can play important role in treatment. The aim of this study was to examine morphological changes in injured retinal pigment epithelium (RPE) and photoreceptor cells...
متن کاملThe occurrence of actinlike filaments in association with migrating pigment granules in frog retinal pigment epithelium
In the retina of the frog and certain other animals, melanin pigment granules move in response to light so as to shield photoreceptor outer segments. The granules are contained within the cells of the pigment epithelium (PE) which lie as a continuous sheet between the neural retina and the choroid. Moderate illumination of the eye causes the melanin granules to move from a region within a PE ce...
