There are two categories of glutamic acid receptors: ionic receptors and metabolic receptors. N-Methyl-D-Aspartate (NMDA) receptor is a subtype of ionic receptors. NMDA receptor mediates the calcium influx, promotes the synaptic plasticity, and participates in process of learning, memory and neurogenesis. On the other hand, excessive excitatory amino acids can excite NMDA receptor, and causes calcium influx, intracellular calciumoverload, further activates a series of intracellular mechanisms inducing the apoptosis. So NMDA receptor has been considered as a double-edged sword in central nervous system. The disturbance of activation regulation of NMDA receptors could be the basis of a plenty of central nervous system diseases including neurodegenerative diseases, epilepsy, ischemic cerebral injury, etc. This article reviews the relationship between NMDA receptors and neurodegenerative diseases.
