Threohydroxyaspartate (THA)-induced glutamate excitotoxicity in organotypic culture of rat spinal cord is a well-known model of motor neuron degeneration. THA causes accumulation of synaptic glutamate and over stimulation of the postsynaptic receptor by inhibiting glutamate uptake. This model has also

Activity of high-affinity glutamate transporters was altered in brain nerve terminals under artificial gravity conditions. Blood platelets contain glutamate transporters and are able to uptake glutamate. The goal of the research was to analyze comparatively L-[14C]glutamate transport in neuronal and
