Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway

Advanced Science, EarlyView.
Astrocytic FABP5 promotes mitochondrial stress, cGAS‐STING pathway activation, pyroptosis, and neuroinflammation in epilepsy, contributing to seizure pathology. Genetic targeting of FABP5 or pharmacological inhibition of STING alleviates epileptic phenotypes, highlighting a potential therapeutic strategy for epilepsy.

Excitotoxicity-Associated p53 Expression in Adult Rat Retina Is Mediated by Calpain Activity but Not by Cl− Influx

Journal of Pharmacological Sciences, 2009
.: We have previously demonstrated an important role of influx of Cl− rather than Ca2+ in acute excitotoxicity in adult rat retina. As p53 has been implicated in delayed apoptotic cell death, here we examined the appearance of p53 immunoreactivity in a ...

Protective effect of naringenin on glutamate-induced neurotoxicity in cultured hippocampal cells [PDF]

Archives of Biological Sciences, 2015
Monosodium glutamate induces excitotoxicity in the central nervous system through hyperactivation of both ionotropic and metabotropic glutamate receptors, which leads to neuronal cell death.

Functionalized Biomimetic Scaffolds for Human‐Derived Auditory Neural Circuit Construction

Advanced Science, EarlyView.
In Vitro Auditory Circuit Model. ABSTRACT Damage to auditory circuits results in sensorineural hearing loss. However, the scarcity of human inner ear tissue significantly hinders the development of therapies to preserve auditory function, creating a critical need for reliable in vitro models.

Enriched environment inhibits GLT-1 ubiquitination by downregulating SMURF1 to attenuate ischemic brain injury induced excitotoxicity

Cell & Bioscience
Background Excitotoxicity induced by glutamate contributes significantly to ischemic brain injury. The role of enriched environment (EE) in promoting neurological recovery post-stroke is well-established, yet its impact on excitotoxicity remains unclear.

Polydopamine Nanoparticle‐Mediated Precise Near‐Infrared Optical Stimulation for Cognitive Enhancement

Advanced Science, EarlyView.
Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.

Excitotoxic inactivation of constitutive oxidative stress detoxification pathway in neurons can be rescued by PKD1

Nature Communications, 2017
Excitotoxicity due to excessive glutamate release causes oxidative stress and neuronal death, and is a feature of many brain diseases. Here the authors show that protein kinase D1 is inactivated by excitotoxicity in a model of stroke and that its ...

Phosphorylation of tau at Y18, but not tau-fyn binding, is required for tau to modulate NMDA receptor-dependent excitotoxicity in primary neuronal culture

Molecular Neurodegeneration, 2017
Background Hyperexcitability of neuronal networks can lead to excessive release of the excitatory neurotransmitter glutamate, which in turn can cause neuronal damage by overactivating NMDA-type glutamate receptors and related signaling pathways.

Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

Advanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...

VEGFD Protects Retinal Ganglion Cells and, consequently, Capillaries against Excitotoxic Injury

Molecular Therapy: Methods & Clinical Development, 2020
In the central nervous system, neurons and the vasculature influence each other. While it is well described that a functional vascular system is trophic to neurons and that vascular damage contributes to neurodegeneration, the opposite scenario in which ...
