[Glutamate receptors in the central nervous system]

A lot of clinical processes following excessive stimulation of glutamate receptors seem to participate in pathophysiology of numerous acute and chronic neurological disorders. The whole of these reactions has been named as "glutamate cascade", because of the central role of glutamate in initiation and intensification of these processes. In this article, classification of different types of glutamate receptors and several hypotheses concerning mechanisms of glutamate neurotoxic activity are presented. A wide variety of neurological diseases, which etiologies are more or less connected with glutamate toxicity are discussed. At last, the future perspectives for treatment by drugs which action is thought to be mediated through glutamate receptors are presented.
