Evoked release of glutamate and aspartate from cultured cerebellar granule cells was studied after preincubation of the cells in tissue culture medium with glucose (6.5 mM), glutamine (1.0 mM),d[3H] aspartate and in some cases aminooxyacetate (5.0 mM) or phenylsuccinate (5.0 mM). The release of endogenous amino acids and ofd-[3H] aspartate was measured(More)
A flux analysis model for the metabolism of neurotransmitter glutamate is constructed, in order to study functional aspects of its metabolism. This work is based on the potassium [K(+)] evoked neurotransmitter glutamate released, as measured in a series of experiments of superfused rat or mouse brain preparations. These measurements are combined with data(More)
An in-silico model, of the glucocorticoid regulated glutamate release, in rat hippocampal tissue, is constructed. The model permits the pseudo-steady state estimation of various fluxes, experimentally impossible to measure, from a set of measured rates. Estimates of the astrocytic pyruvate carboxylase reaction and the neuronal TCA cycle rates are correlated(More)
