NMDA receptors are key molecules involved in physiological and pathophysiological brain processes such as plasticity and excitotoxicity. Neuronal activity regulates NMDA receptor levels in the cell membrane.

Provocative emerging evidence suggests that the N-methyl-D-aspartate (NMDA) receptor can signal in the absence of ion flux through the receptor. This non-ionotropic signaling is thought to be due to agonist-induced conformational changes in the receptor,

Three-level multilevel simulation of the neuroreceptor function of NMDA [PDF]
We present a new multiscale method to study the N-Methyl-D-Aspartate (NMDA) neuroreceptor starting from the reconstruction of its crystallographic structure. Thanks to the combination of homology modelling, Molecular Dynamics and Lattice Boltzmann simulations, we analyse the allosteric transition of NDMA upon ligand binding and compute the receptor ...

Cellular prion protein and NMDA receptor modulation: protecting against excitotoxicity
Although it is well established that misfolding of the cellular prion protein (PrPC) into the beta-sheet-rich, aggregated scrapie conformation (PrPSc) causes a variety of transmissible spongiform encephalopathies (TSEs), the physiological roles of PrPC ...

Differential Effects of D-Cycloserine and ACBC at NMDA Receptors in the Rat Entorhinal Cortex Are Related to Efficacy at the Co-Agonist Binding Site. [PDF]
Partial agonists at the NMDA receptor co-agonist binding site may have potential therapeutic efficacy in a number of cognitive and neurological conditions. The entorhinal cortex is a key brain area in spatial memory and cognitive processing.

Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy
ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...

NMDA receptor function during senescence: implication on cognitive performance
N-methyl-D-aspartate (NMDA) receptors, a family of L-glutamate receptors, play an important role in learning and memory, and are critical for spatial memory. These receptors are tetrameric ion channels composed of a family of related subunits. One of the

DMV extrasynaptic NMDA receptors regulate caloric intake in rats
Acute high-fat diet (aHFD) exposure induces a brief period of hyperphagia before caloric balance is restored. Previous studies have demonstrated that this period of regulation is associated with activation of synaptic N-methyl-D-aspartate (NMDA ...
