N-methyl-D-aspartate receptor plasticity in kindling: quantitative and qualitative alterations in the N-methyl-D-aspartate receptor-channel complex.

Kindling is an animal model of epilepsy and neuronal plasticity produced by periodic electrical stimulation of the brain. Electrophysiologic studies indicate that this phenomenon is associated with increased participation of N-methyl-D-aspartate (NMDA) receptors in excitatory synaptic transmission. Biochemical studies suggest that a change intrinsic to the NMDA receptor-channel complex may cont...

Combined Therapy for Anti-N-methyl D-aspartate Receptor Encephalitis

Background Anti-N-methyl- d-aspartate receptor (anti-NMDAR) encephalitis is an autoimmune neurological disorder that usually occurs as a paraneoplastic syndrome and is particularly associated with ovarian teratoma. Standard therapy for severe cases is not established and the prognosis in patients who do not respond to first-line treatment is poor. Case Report An 11-year-old boy complained ps...

The N-Methyl-D-Aspartate Receptor in Cerebral Ischemia

Excitotoxicity is a major mechanism of neuronal damage in cerebral ischemia and is mediated largely by neuronal N-methyl-D-aspartate receptors (NMDAR). This review presents the structural and functional alterations in NMDAR after an ischemic insult, including the antagonistic roles different NMDAR sub-types play in the post-ischemic period. By elucidating these molecular changes and the effects...

Interaction of aquaporin 4 and N-methyl-D-aspartate NMDA receptor 1 in traumatic brain injury of rats

Objective(s): -methyl-D-aspartate NMDA receptor (NMDAR) and aquaporin 4 (AQP4) are involved in the molecular cascade of edema after traumatic brain injury (TBI) and are potential targets of studies in pharmacology and medicine. However, their association and interactions are still unknown.Materials and Methods: We established a rat TBI model in this study. The cellular distribution patterns of ...

The effect of morphine dependence on expression of hippocampal N-methyl-D-aspartate receptor subunits in male rats

Introduction: N-methyl-D-aspartate (NMDA) receptors play a pivotal role in the development of tolerance and physical dependence to opiates. Activation of NMDA receptors involves the induction of long term potentiation (LTP) in hippocampus. Our previous study suggested that chronic oral administration of morphine enhanced NMDA dependent LTP in the CA1 area of hippocampal slices of rats. The p...
