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 ...

Mfn2 downregulation in excitotoxicity causes mitochondrial dysfunction and delayed neuronal death [PDF]
EMBO Journal, 2014 Mitochondrial fusion and fission is a dynamic process critical for the maintenance of mitochondrial function and cell viability. During excitotoxicity neuronal mitochondria are fragmented, but the mechanism underlying this process is poorly understood ...

Retrograde transport of neurotrophin receptor TrkB-FL induced by excitotoxicity regulates Golgi stability and is a target for stroke neuroprotection [PDF]
Cell Death and DiseaseExcitotoxicity, aberrant function of survival pathways dependent on brain-derived neurotrophic factor (BDNF), and disruption of the Golgi complex are shared pathological hallmarks in relevant neurological diseases, including stroke.

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.

The initiator of neuroexcitotoxicity and ferroptosis in ischemic stroke: Glutamate accumulation
Frontiers in Molecular Neuroscience, 2023 Glutamate plays an important role in excitotoxicity and ferroptosis. Excitotoxicity occurs through over-stimulation of glutamate receptors, specifically NMDAR, while in the non-receptor-mediated pathway, high glutamate concentrations reduce cystine ...

Various facets of excitotoxicity
Exploration of Neuroprotective Therapy, 2022 Aim: Excitotoxicity results from unusually increased activation of excitatory amino acid receptors leading to neuronal death. Since glutamate is the main excitatory neurotransmitter in the central nervous system, it is also the most common ...

Molecular mechanisms of NMDA excitotoxicity in the retina
Scientific Reports, 2023 NMDA excitotoxicity, as a part of glutamate excitotoxicity, has been proposed to contribute significantly to many retinal diseases. Therefore, understanding mechanisms of NMDA excitotoxicity will provide further insight into the mechanisms of many ...
