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

open access: yesNeural 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.

S‐ketamine Alleviates Neuroinflammation and Attenuates Lipopolysaccharide‐Induced Depression Via Targeting SIRT2

open access: yesAdvanced Science, EarlyView.
S‐ketamine binds directly to SIRT2, facilitating its interaction with NF‐κB p65. This interaction reduces the acetylation of NF‐κB p65 and inhibits its activation, thereby exerting anti‐inflammatory and antidepressant effects. Created by BioRender.

A biophysical network model reveals the link between deficient inhibitory cognitive control and major neurotransmitter and neural connectivity hypotheses in schizophrenia [PDF]

open access: yesarXiv, 2021
We address a biophysical network dynamical model to study how the modulation of dopamine (DA) activity and related N-methyl-d-aspartate (NMDA) glutamate receptor activity as well as the emerging Pre-Frontal Cortex (PFC) functional connectivity network (FCN) affect inhibitory cognitive function in schizophrenia in an antisaccade task.

Pathologically Activated Neuroprotection via Uncompetitive Blockade of \u3cem\u3eN\u3c/em\u3e-Methyl-d-aspartate Receptors with Fast Off-rate by Novel Multifunctional Dimer Bis(propyl)-cognitin [PDF]

open access: yes, 2010
Uncompetitive N-methyl-d-aspartate (NMDA) receptor antagonists with fast off-rate (UFO) may represent promising drug candidates for various neurodegenerative disorders.

NMDA But Not Non-NMDA Excitotoxicity is Mediated by Poly(ADP-Ribose) Polymerase [PDF]

open access: yesThe Journal of Neuroscience, 2000
Poly(ADP-ribose) polymerase (PARP-1), a nuclear enzyme that facilitates DNA repair, may be instrumental in acute neuronal cell death in a variety of insults including, cerebral ischemia,1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced parkinsonism, and CNS trauma. Excitotoxicity is thought to underlie these and other toxic models of neuronal death.

Hippocampal glutamate NMDA receptor loss tracks progression in Alzheimer's disease: quantitative autoradiography in postmortem human brain. [PDF]

open access: yesPLoS ONE, 2013
Early Alzheimer's disease (AD) is characterized by memory loss and hippocampal atrophy with relative sparing of basal ganglia. Activation of glutamate NMDA receptors in the hippocampus is an important step in memory formation.

An Electrolyte‐Gated InGaZnO Phototransistor that Emulates Visual Experience‐Dependent Plasticity

open access: yesAdvanced Electronic Materials, EarlyView.
By utilizing the light‐history‐dependent property of the IGZO electrolyte‐gated transistor, Bienenstock‐Cooper‐Munro (BCM) learning rule is successfully emulated. Moreover, the BCM learning rule enables a variety of bionic vision functions including image edge detection and associative memory, which offers a promising route for simulating high‐order ...

Excitatory amino acids and intracellular pH in motoneurons of the isolated frog spinal cord [PDF]

open access: yes, 1986
Double-barrelled pH-sensitive micro-electrodes were used to measure changes of intracellular and extracellular pH in and around motoneurons of the isolated frog spinal cord during application of excitatory amino acids.

Endocytosis of GluN2B-containing NMDA receptor mediates NMDA-induced excitotoxicity [PDF]

open access: yesMolecular Pain, 2017
N-methyl-D-aspartate (NMDA) receptor overactivation is involved in neuronal damage after stroke. However, the mechanism underlying NMDA receptor-mediated excitotoxicity remains unclear. In this study, we confirmed that excessive activation of NMDARs led to cell apoptosis in PC12 cells and in primary cultured cortical neurons, which was mediated ...

NMDA Receptor Modulators in the Treatment of Drug Addiction

open access: yesPharmaceuticals, 2013
Glutamate plays a pivotal role in drug addiction, and the N-methyl-D-aspartate (NMDA) glutamate receptor subtype serves as a molecular target for several drugs of abuse. In this review, we will provide an overview of NMDA receptor structure and function,
