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 ...

Potential protective roles of phytochemicals on glutamate-induced neurotoxicity: A review [PDF]

Iranian Journal of Basic Medical Sciences, 2020
Glutamate, as an essential neurotransmitter, has been thought to have different roles in the central nervous system (CNS), including nerve regeneration, synaptogenesis, and neurogenesis.

nNOS(+) striatal neurons, a subpopulation spared in Huntington's Disease, possess functional NMDA receptors but fail to generate mitochondrial ROS in response to an excitotoxic challenge. [PDF]

, 2013
Huntington's disease (HD) is a neurodegenerative condition characterized by severe neuronal loss in the cortex and striatum that leads to motor and behavioral deficits.

A circuit-dependent ROS feedback loop mediates glutamate excitotoxicity to sculpt the Drosophila motor system

eLife, 2019
Overproduction of reactive oxygen species (ROS) is known to mediate glutamate excitotoxicity in neurological diseases. However, how ROS burdens can influence neural circuit integrity remains unclear.

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]

, 2017
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.

Absence of system xc⁻ on immune cells invading the central nervous system alleviates experimental autoimmune encephalitis [PDF]

, 2017
Background: Multiple sclerosis (MS) is an autoimmune demyelinating disease that affects the central nervous system (CNS), leading to neurodegeneration and chronic disability.

Intrinsic up-regulation of 2-AG favors an area specific neuronal survival in different in vitro models of neuronal damage [PDF]

, 2012
BACKGROUND: The endocannabinoid 2-arachidonoyl glycerol (2-AG) acts as a retrograde messenger and modulates synaptic signaling e. g. in the hippocampus. 2-AG also exerts neuroprotective effects under pathological situations.

Ambient but not local lactate underlies neuronal tolerance to prolonged glucose deprivation [PDF]

, 2018
Neurons require a nearly constant supply of ATP. Glucose is the predominant source of brain ATP, but the direct effects of prolonged glucose deprivation on neuronal viability and function remain unclear.
