Neuroprotective Effects of Daphnetin against NMDA Receptor-Mediated Excitotoxicity
Molecules, 2014 The accumulation of glutamate can excessively activate the N-methyl-d-aspartate (NMDA) receptors and cause excitotoxicity. Daphnetin (Dap), a coumarin derivative, is a protein kinase inhibitor that exhibits antioxidant and neuroprotective properties ...

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.

Biomaterials to Neuroprotect the Stroke Brain: A Large Opportunity for Narrow Time Windows
Cells, 2020 Ischemic stroke represents one of the most prevalent pathologies in humans and is a leading cause of death and disability. Anti-thrombolytic therapy with tissue plasminogen activator (t-PA) and surgical thrombectomy are the primary treatments to ...

Targeting CDK5 in Astrocytes Promotes Calcium Homeostasis Under Excitotoxic Conditions
Frontiers in Cellular Neuroscience, 2021 Glutamate excitotoxicity triggers overactivation of CDK5 and increases calcium influx in neural cells, which promotes dendritic retraction, spine loss, increased mitochondrial calcium from the endoplasmic reticulum, and neuronal death.

FGF-2 Induces Neuronal Death through Upregulation of System xc- [PDF]
, 2014 The cystine/glutamate antiporter (system xc-) transports cystine into cell in exchange for glutamate. Fibroblast growth factor-2 (FGF-2) upregulates system xc- selectively on astrocytes, which leads to increased cystine uptake, the substrate for ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Subtotal hippocampal resection can leave residual hippocampal tissue, yet the immediate postoperative electrophysiologic evolution of such remnants is unknown. We describe a patient with drug‐resistant temporal lobe epilepsy in whom a hippocampal remnant was continuously monitored using a responsive neurostimulator (RNS) following subtotal ...

Nicorandil mitigates glutamate excitotoxicity in primary cultured neurons
Medicine ScienceExcitotoxicity, caused by the excessive release of glutamate, leads to the activation of the apoptotic process, making it a crucial factor in age-related neurodegenerative diseases.

Hyperacute Excitotoxic Mechanisms and Synaptic Dysfunction Involved in Traumatic Brain Injury
Frontiers in Molecular Neuroscience, 2022 The biological response of brain tissue to biomechanical strain are of fundamental importance in understanding sequela of a brain injury. The time after impact can be broken into four main phases: hyperacute, acute, subacute and chronic. It is crucial to
