Substantia nigra osmoregulation: taurine and ATP involvement.
An extracellular nonsynaptic taurine pool of glial origin was recently reported in the substantia nigra (SN). There is previous evidence showing taurine as an inhibitory neurotransmitter in the SN, but the physiological role of this nonsynaptic pool of taurine has not been explored. By using microdialysis methods, we studied the action of local osmolarity on the nonsynaptic taurine pool in the ...
متن کاملTaurine transport in epilepsy.
Previous studies of plasma taurine concentrations in epileptics have yielded equivocal results. We measured plasma and urinary taurine in 41 epileptic and 68 control subjects and found plasma concentrations among epileptics to be comparable in general to those of controls, but that two or three classes of plasma taurine concentrations, possibly genetically regulated, occur in both epileptic and...
متن کاملRenal transport of taurine adapts to perturbed taurine homeostasis.
Renal adaptation apparently contributes to the homeostasis of taurine, a beta-amino compound that behaves as a conserved metabolite in the mammal. We studied two strains of inbred mice: C3H/HeJ (low-taurine excreter) and C57BL/6J (high-taurine excreter due to impaired basolateral membrane permeability to taurine). Low-protein and low-sulfur amino acid diets fed for two weeks significantly decre...
متن کاملEffects of Intracellular Zinc Chelator In Vivo on Taurine Transport, Taurine Concentrations and Taurine Transporter in Rat Retina Cells
Taurine and zinc, highly concentrated in the retina, have neurotrophic effects in the central nervous system. Zinc modulates Na+/Cldependent transporters, such as those of dopamine and taurine (TAUT) in vitro, although there is no evidence of in vivo effects of zinc. The objectives of the present study were to evaluate the consequences of zinc deficiency on taurine levels and transport, and mRN...
متن کاملAntenatal taurine reduces cerebral cell apoptosis in fetal rats with intrauterine growth restriction
From pregnancy to parturition, Sprague-Dawley rats were daily administered a low protein diet to establish a model of intrauterine growth restriction. From the 12(th) day of pregnancy, 300 mg/kg rine was daily added to food until spontaneous delivery occurred. Brain tissues from normal neonatal rats at 6 hours after delivery, neonatal rats with intrauterine growth restriction, and neonatal rats...
