Chronic glutamate toxicity in neurodegenerative diseases-what is the evidence?

open access: yesFrontiers in Neuroscience, 2015
Together with aspartate, glutamate is the major excitatory neurotransmitter in the brain. Glutamate binds and activates both ligand-gated ion channels (ionotropic glutamate receptors) and a class of G-protein coupled receptors (metabotropic glutamate ...

AMPA and Kainate Receptors Each Mediate Excitotoxicity in Oligodendroglial Cultures

open access: yesNeurobiology of Disease, 1999
Recent studies indicate that oligodendrocytes are vulnerable to excitotoxic insults mediated by glutamate receptors. The present study was carried out to characterize the type of glutamate receptors triggering cell death in optic nerve oligodendrocyte ...

Phased Treatment Strategies for Cerebral Ischemia Based on Glutamate Receptors

open access: yesFrontiers in Cellular Neuroscience, 2019
Extracellular glutamate accumulation following cerebral ischemia leads to overactivation of glutamate receptors, thereby resulting in intracellular Ca2+ overload and excitotoxic neuronal injury. Multiple attempts have been made to counteract such effects

Modulation of glutamate transport and receptor binding by glutamate receptor antagonists in EAE rat brain. [PDF]

open access: yesPLoS ONE, 2014
The etiology of multiple sclerosis (MS) is currently unknown. However, one potential mechanism involved in the disease may be excitotoxicity. The elevation of glutamate in cerebrospinal fluid, as well as changes in the expression of glutamate receptors ...

Glutamate receptor pores [PDF]

open access: yesThe Journal of Physiology, 2014
AbstractGlutamate receptors are ligand‐gated ion channels that mediate fast excitatory synaptic transmission throughout the central nervous system. Functional receptors are homo‐ or heteromeric tetramers with each subunit contributing a re‐entrant pore loop that dips into the membrane from the cytoplasmic side. The pore loops form a narrow constriction

Cross-talk and regulation between glutamate and GABAB receptors

open access: yesFrontiers in Cellular Neuroscience, 2015
Brain function depends on co-ordinated transmission of signals from both excitatory and inhibitory neurotransmitters acting upon target neurons.

Posttranslational Modification Biology of Glutamate Receptors and Drug Addiction

open access: yesFrontiers in Neuroanatomy, 2011
Posttranslational covalent modifications of glutamate receptors remain a hot topic. Early studies have established that this family of receptors, including almost all ionotropic and metabotropic glutamate receptor subtypes, undergoes active ...

Researching glutamate – induced cytotoxicity in different cell lines: a comparative/, collective analysis/study

open access: yesFrontiers in Cellular Neuroscience, 2015
Although glutamate is one of the most important excitatory neurotransmitters of the central nervous system, its excessive extracellular concentration leads to uncontrolled continuous depolarization of neurons, a toxic process called, excitotoxicity.

Astrocyte Glutamate Uptake and Signaling as Novel Targets for Antiepileptogenic Therapy

open access: yesFrontiers in Neurology, 2020
Astrocytes regulate and respond to extracellular glutamate levels in the central nervous system (CNS) via the Na+-dependent glutamate transporters glutamate transporter-1 (GLT-1) and glutamate aspartate transporter (GLAST) and the metabotropic glutamate ...
