Structural Dynamics and Allosteric Signaling in Ionotropic Glutamate Receptors [PDF]

, 2013
Ionotropic glutamate receptors (iGluRs) are ligand-gated ion channels that mediate excitatory neurotransmission events in the central nervous system. All distinct classes of iGluRs (AMPA, NMDA, Kainate) are composed of an N-terminal domain (NTD) and a ...

Memantine prevents acute stress‐induced memory deficits by reversing sex‐dependent pathophysiological glutamatergic alterations in the dorsal hippocampus

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The neural mechanisms underlying effects of acute stress on memory are poorly understood. We demonstrated previously that acute stress produces identical spatial memory deficits in male and female mice but through distinct molecular mechanisms, with females exhibiting up‐regulation of N‐methyl‐D‐aspartate (NMDA) receptor

Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

AMPA receptor trafficking and synaptic plasticity

, 2002
Activity-dependent changes in synaptic function are believed to underlie the formation of memories. Two prominent examples are long-term potentiation (LTP) and long-term depression (LTD), whose mechanisms have been the subject of considerable scrutiny ...

Noise‐induced reduction and early recovery of superior paraolivary nucleus sound‐offset responses

The Journal of Physiology, EarlyView.
Abstract figure legend Acoustic over‐exposure transiently disrupts auditory temporal processing in mouse superior paraolivary nucleus neurons. In control conditions, neurons exhibit robust sound‐offset (OFF) responses, which are abolished immediately following noise trauma, indicating impaired temporal encoding.

Quantitative analysis of the interaction between NMDA and AMPA receptors in glutamatergic synapses based on mathematical model

Neuroscience Research
NMDA and AMPA receptors are co-localized at most glutamatergic synapses, where their numbers and distribution undergo dynamic changes. Glutamate binds to both the NMDA and AMPA receptors.

In vivo co-ordinated interactions between inhibitory systems to control glutamate mediated hippocampal excitability.

, 2013
We present an overview of the long-term adaptation of hippocampal neurotransmission to cholinergic and GABAergic deafferentation caused by excitotoxic lesion of the medial septum.

Hypoxia‐induced vulnerability of the somatosensory nervous system

The Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Potentiation of glycine-gated NR1/NR3A NMDA receptors relieves Ca2+-dependent outward rectification

, 2010
Glycine has diverse functions within the mammalian central nervous system. It inhibits postsynaptic neurons via strychnine-sensitive glycine receptors (GlyRs) and enhances neuronal excitation through co-activation of N-methyl-D-aspartate (NMDA) receptors.
