GluN2C/D‐containing NMDA receptors enhance temporal summation and increase sound‐evoked and spontaneous firing in the inferior colliculus

The Journal of Physiology, EarlyView.
Abstract figure legend Here, we find that GluN2D‐containing NMDA receptors (NMDARs) are expressed by most vasoactive intestinal peptide neurons in the inferior colliculus (IC). These receptors are less susceptible to Mg2+ blockade compared to GluN2A/B‐containing NMDARs, allowing ions to flow at resting membrane potential.

Presynaptic and extrasynaptic regulation of posterior nucleus of thalamus [PDF]

Journal of Neurophysiology, 2017
The posterior nucleus of thalamus (PO) is a higher-order nucleus involved in sensorimotor processing, including nociception. An important characteristic of PO is its wide range of activity profiles that vary across states of arousal, thought to underlie differences in somatosensory perception subject to attention and degree of consciousness ...

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system

British Journal of Pharmacology, Volume 182, Issue 14, Page 3178-3210, July 2025.
G protein‐coupled receptors (GPCRs) are a large family of cell surface receptors that play a critical role in nervous system function by transmitting signals between cells and their environment. They are involved in many, if not all, nervous system processes, and their dysfunction has been linked to various neurological disorders representing important

BDNF Reduces Toxic Extrasynaptic NMDA Receptor Signaling via Synaptic NMDA Receptors and Nuclear-Calcium-Induced Transcription of inhba/Activin A

Cell Reports, 2015
The health of neurons is critically dependent on the relative signaling intensities of survival-promoting synaptic and death-inducing extrasynaptic NMDA receptors.

Rescue of Epilepsy‐Associated Mutations of the Highly Conserved Glycine Residue 443 in the Human GABA Transporter 1

The FASEB Journal, Volume 39, Issue 11, 15 June 2025.
Mutations in the human GABA transporter 1 (hGAT‐1) gene impair GABA transport, leading to developmental disorders like epilepsy and autism. These mutations often disrupt protein folding. Pharmacochaperones can rescue transporter expression and function in heterologous cell lines and in Drosophila melanogaster, thus offering potential therapeutic ...

Super-resolution imaging of synaptic and Extra-synaptic AMPA receptors with different-sized fluorescent probes

eLife, 2017
Previous studies tracking AMPA receptor (AMPAR) diffusion at synapses observed a large mobile extrasynaptic AMPAR pool. Using super-resolution microscopy, we examined how fluorophore size and photostability affected AMPAR trafficking outside of, and ...

Extrasynaptic GABA(A) receptors and tonic inhibition in rat auditory thalamus. [PDF]

PLoS ONE, 2011
Neural inhibition plays an important role in auditory processing and attentional gating. Extrasynaptic GABA(A) receptors (GABA(A)R), containing α(4)and δ GABA(A)R subunits, are thought to be activated by GABA spillover outside of the synapse following ...

A Proteomics Profiling Reveals the Neuroprotective Effects of Melatonin on Exogenous β‐amyloid‐42 Induced Mitochondrial Impairment, Intracellular β‐amyloid Accumulation and Tau Hyperphosphorylation in Human SH‐SY5Y Cells

Cell Biology International, Volume 49, Issue 6, Page 659-673, June 2025.
ABSTRACT Alzheimer's disease (AD) is prevalent in the elderly population and characterized by the intracellular accumulation of neurofibrillary tangles (NFTs), composed of tau proteins, and extracellular deposition of beta‐amyloid protein (Aβ). The present study aimed to investigate the neuroprotective effects of melatonin on Aβ42‐induced AD‐like ...

Membrane progesterone and oestrogen receptors modulate GABAergic transmission in the prefrontal cortex of prepubertal male, but not female, mice

Experimental Physiology, Volume 110, Issue 6, Page 888-898, 1 June 2025.
Abstract The sex hormones progesterone (P) and oestrogen (E) reorganize GABAergic transmission in the prefrontal cortex (PFC) during the transition from childhood to adolescence, generating a new excitatory–inhibitory balance necessary for the computational capacity of the mature PFC.

Meprin β Modulates Brevican Proteolysis Impairing Neural Plasticity and Memory Formation

The FASEB Journal, Volume 39, Issue 10, 31 May 2025.
Meprin β was studied using mice overexpressing it in cortical and hippocampal neurons. N‐terminomics identified brevican, a key extracellular matrix protein associated with synaptic plasticity and memory, as a potential substrate of meprin β. Further analyses revealed that brevican levels are dependent on the catalytic activity of meprin β.
