TRPM4 blocking antibody reduces neuronal excitotoxicity by specifically inhibiting glutamate-induced calcium influx under chronic hypoxia

open access: yesNeurobiology of Disease
Excitotoxicity arises from unusually excessive activation of excitatory amino acid receptors such as glutamate receptors. Following an energy crisis, excitotoxicity is a major cause for neuronal death in neurological disorders. Many glutamate antagonists

Selective up-regulation of the glial Na+-dependent glutamate transporter GLT1 by a neuroimmunophilin ligand results in neuroprotection

open access: yesNeurobiology of Disease, 2006
Excessive accumulation of extracellular glutamate results in neuronal death. Termination of synaptic glutamate transmission and the prevention of excitotoxicity depend on rapid removal of glutamate by high affinity Na+-dependent transporters.

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

open access: yesThe FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Astrocytic connexin43 phosphorylation contributes to seizure susceptibility after mild traumatic brain injury

open access: yesThe FEBS Journal, EarlyView.
Astrocytic gap junctions formed by connexin43 (Cx43) help maintain brain homeostasis. After mild traumatic brain injury (TBI), total cortical Cx43 increases and redistributes toward a soluble, non‐junctional pool with elevated hemichannel activity and increased phosphorylation at serine 368 (pCx43S368).

Full‐Spectrum Medicinal Cannabis Plant Extract 0.08% THC (NTI164) Improves Symptoms of Rett Syndrome: An Open‐Label Study

open access: yesJournal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim The aim of this Phase I/II open‐label study was to assess the safety and efficacy of NTI164, a novel full‐spectrum medicinal cannabis plant extract 0.08% Δ‐9‐tetrahydrocannabinol (THC), in Rett syndrome (RTT). Methods Eleven female participants (5–16 years) with a pathogenic variant in the MECP2 gene were recruited to this study, receiving

AMPA and metabotropic excitoxicity explain subplate neuron vulnerability

open access: yesNeurobiology of Disease, 2010
Cerebral hypoxia–ischemia results in unique patterns of injury during development owing to selective vulnerability of specific cell populations including subplate neurons.

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

open access: yesThe 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 ...

Amacrine cell inputs to OFF midget ganglion cells in macaque retina

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...

Neuroprotective Effects of Daphnetin against NMDA Receptor-Mediated Excitotoxicity

open access: yesMolecules, 2014
The accumulation of glutamate can excessively activate the N-methyl-d-aspartate (NMDA) receptors and cause excitotoxicity. Daphnetin (Dap), a coumarin derivative, is a protein kinase inhibitor that exhibits antioxidant and neuroprotective properties ...

Hypoxia‐induced vulnerability of the somatosensory nervous system

open access: yesThe 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 ...
