Going the Extra (Synaptic) Mile: Excitotoxicity as the Road Toward Neurodegenerative Diseases
Frontiers in Cellular Neuroscience, 2020 Excitotoxicity is a phenomenon that describes the toxic actions of excitatory neurotransmitters, primarily glutamate, where the exacerbated or prolonged activation of glutamate receptors starts a cascade of neurotoxicity that ultimately leads to the loss

Calcium Permeable-AMPA Receptors and Excitotoxicity in Neurological Disorders
Frontiers in Neural Circuits, 2021 Excitotoxicity is one of the primary mechanisms of cell loss in a variety of diseases of the central and peripheral nervous systems. Other than the previously established signaling pathways of excitotoxicity, which depend on the excessive release of ...

Insulin Protects Cortical Neurons Against Glutamate Excitotoxicity
Frontiers in Neuroscience, 2019 Glutamate excitotoxicity is implicated in the pathogenesis of numerous diseases, such as stroke, traumatic brain injury, and Alzheimer’s disease, for which insulin resistance is a concomitant condition, and intranasal insulin treatment is believed to be ...

Excitotoxic inactivation of constitutive oxidative stress detoxification pathway in neurons can be rescued by PKD1 [PDF]
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 ...

The Susceptibility of Retinal Ganglion Cells to Glutamatergic Excitotoxicity Is Type-Specific
Frontiers in Neuroscience, 2019 Retinal ganglion cells (RGCs) are the only output neurons that conduct visual signals from the eyes to the brain. RGC degeneration occurs in many retinal diseases leading to blindness and increasing evidence suggests that RGCs are susceptible to various ...

Axonal degeneration induced by glutamate excitotoxicity is mediated by necroptosis [PDF]
Journal of Cell Science, 2018 Neuronal excitotoxicity induced by glutamate leads to cell death and functional impairment in a variety of central nervous system pathologies. Glutamate-mediated excitotoxicity triggers neuronal apoptosis in the cell soma as well as degeneration of axons

Does umbelliferone protect primary cortical neuron cells against glutamate excitotoxicity [PDF]
Kafkas Universitesi Veteriner Fakültesi Dergisi, 2021 Glutamate is the major excitatory neurotransmitter in the central nervous system. Excessive glutamate is known to cause excitotoxicity. Umbelliferone is a coumarin derivative compound and has anti-oxidant, anti-infl ammatory, and neuroprotective eff ects.

Excitotoxicity, calcium and mitochondria: a triad in synaptic neurodegeneration
Translational Neurodegeneration, 2022 Glutamate is the most commonly engaged neurotransmitter in the mammalian central nervous system, acting to mediate excitatory neurotransmission. However, high levels of glutamatergic input elicit excitotoxicity, contributing to neuronal cell death ...
