Abstract:
Glutamate is a kind of excitatory transmitter in the central nervous system of mammals; at the same time, being with excitatory toxicity, its extracellular concentration is mainly modulated by the glutamate transporters. In the case of hypoxic-ischemia, the energy failure would lead to the generation of lactate and free radical, and to the crash of [Na+] gradient, thus exerting influence on the activity and the expression of glutamate transporters. As a result, the glutamate accumulates in the synaptic cleft, activates the glutamate receptors, and causes the death of neurons.
