Integrated Regulation of Signal Coding and Plasticity by NMDA Receptors at a Central Synapse

Neural Plasticity, 1998
The role of NMDA and non-NMDA glutamate receptors in long-term potentiation has been intensely investigated, yet recent evidence on the dynamics of synaptic depolarization suggests that the original view should be extended.

Dysregulation of erythropoiesis and altered erythroblastic NMDA receptor-mediated calcium influx in Lrfn2-deficient mice.

PLoS ONE, 2021
LRFN2 encodes a synaptic adhesion-like molecule that physically interacts with N-methyl-D-aspartate (NMDA) receptor 1 and its scaffold proteins. Previous studies in humans and mice have demonstrated its genetic association with neurodevelopmental ...

NMDA receptor structures reveal subunit arrangement and pore architecture

Nature, 2014
N-methyl-d-aspartate (NMDA) receptors are Hebbian-like coincidence detectors, requiring binding of glycine and glutamate in combination with the relief of voltage-dependent magnesium block to open an ion conductive pore across the membrane bilayer ...

Adult‐Onset Subacute Sclerosing Panencephalitis Presenting With Subacute Cognitive Deficits

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We describe the case of a 41‐year‐old man diagnosed with adult‐onset subacute sclerosing panencephalitis (SSPE). The patient presented with subacute progressive cognitive deficits and a neuropsychological profile indicating predominant frontoparietal dysfunction. MRI showed only mild parietal‐predominant cerebral atrophy.

NMDA-receptor activation but not ion flux is required for amyloid-beta induced synaptic depression. [PDF]

PLoS ONE, 2013
Alzheimer disease is characterized by a gradual decrease of synaptic function and, ultimately, by neuronal loss. There is considerable evidence supporting the involvement of oligomeric amyloid-beta (Aβ) in the etiology of Alzheimer's disease ...

NMDA receptor inhibition increases, synchronizes, and stabilizes the collective pancreatic beta cell activity: Insights through multilayer network analysis.

PLoS Computational Biology, 2021
NMDA receptors promote repolarization in pancreatic beta cells and thereby reduce glucose-stimulated insulin secretion. Therefore, NMDA receptors are a potential therapeutic target for diabetes.

Changes in Striatal N-methyl-D-aspartate (NMDA) Stimulation of Dopamine Release and Receptor Subunit Expression During Expression of and Recovery from MPTP-Induced Parkinsonism [PDF]

, 2001
Normal and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-treated cats were used to examine changes in N-methyl-D-aspartate (NMDA) receptor function.

A 3D Biofabricated Disease Model Mimicking the Brain Extracellular Matrix Suitable to Characterize Intrinsic Neuronal Network Alterations in the Presence of a Breast Tumor Disseminated to the Brain

Advanced Functional Materials, EarlyView.
A 3D disease model is developed using customized hyaluronic‐acid‐based hydrogels supplemented with extracellular matrix (ECM) proteins resembling brain ECM properties. Neurons, astrocytes, and tumor cells are used to mimic the native brain surrounding.

Functional Proteins Involved in Regulation of Intracellular Ca2+ for Drug Development: Desensitization of N-Methyl-D-aspartate Receptor Channels

Journal of Pharmacological Sciences, 2005
N-Methyl-D-aspartate (NMDA) receptors are a principal subtype of excitatory ligand-gated ion channels with crucial roles in a variety of physiological and pathological processes in the mammalian central nervous system (CNS).
