Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, Volume 100, Issue 5, Page 948-961, November 2026.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Glutamate Excitotoxicity: A Key Secondary Injury Mechanism of Traumatic Brain Injury and Spinal Cord Injury

Frontiers in Bioscience-Landmark
Glutamate excitotoxicity is one of the key factors in the pathophysiology of the secondary injury cascade following traumatic brain injury (TBI) and spinal cord injury (SCI). These neurotraumatic conditions remain major causes of long-term disability and

Real‐Time Neurochemical Sensing in Zebrafish: Electrochemical and Fluorescent Approaches

Analysis &Sensing, Volume 6, Issue 6, November 2026.
The use of zebrafish has emerged as a powerful approach for real‐time neurochemical measurements. This review highlights recent advances in electrochemical and fluorescent sensing strategies that enable dynamic measurements in live preparations of this complex vertebrate. These complementary approaches provide new insights into neurochemical signaling,

Gypenoside XVII Reduces Synaptic Glutamate Release and Protects against Excitotoxic Injury in Rats

Biomolecules
Excitotoxicity is a common pathological process in neurological diseases caused by excess glutamate. The purpose of this study was to evaluate the effect of gypenoside XVII (GP-17), a gypenoside monomer, on the glutamatergic system.

Beneficial Role of Natural Polyphenols Against Epilepsy: Greasing the Wheels of Pharmacotherapy Research for Epilepsy

Food Frontiers, Volume 7, Issue 6, November 2026.
ABSTRACT Epilepsy is the most disabling neurological disease that affects all economic classes, age groups, regions, and races. Although many antiseizure drugs are approved for epilepsy treatment, they fail to work in about 30%–40% of patients. Thus, there is a great need to identify better pharmacological agents to treat epilepsy.

Persisting Region‐Specific Microglia Activation and Synaptic Imbalance During Remission in a DSS‐Induced Colitis Model

Glia, Volume 74, Issue 11, November 2026.
Relapsing colitis region‐specific microglial states beyond remission. Cortical microglia remain pro‐inflammatory and synapse‐disruptive, while hippocampal microglia shift toward a reparative program that maintains neuronal circuit stability. ABSTRACT Ulcerative colitis (UC) patients experience cycles of active gut inflammation and remission, with ...

Tannic Acid Mitigates Monosodium Glutamate‐Induced Cortical Damage by Modulating Synaptic and Calcium‐Related Gene and Protein Expression

Journal of Applied Toxicology, Volume 46, Issue 11, Page 4099-4111, November 2026.
ABSTRACT Neurotoxicity induced by excessive glutamatergic signaling is associated with synaptic dysfunction, calcium imbalance, and oxidative stress, which are key molecular events implicated in several neurodegenerative conditions. Monosodium glutamate (MSG), a common flavor enhancer, may exert neurotoxic effects, particularly on synaptic integrity ...

Dose‐Dependent Autophagic Dysfunction and CCR5‐Mediated Neuroinflammation Drive Arsenic Trioxide‐Induced Cortical Neurodegeneration in Mice

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.
Exposure to arsenic trioxide (As2O3) in humans is associated with dose‐dependent cortical neurodegeneration with convergent pathological mechanisms. Low and medium dose exposure induces adaptive autophagy via PI3K/AKT/mTOR suppression and high dose exposure leads to mTOR hyperactivation, autophagic failure, microglial neuroinflammation and excitotoxic ...

The Role of Astrocytes in the Inflammatory Response in Neurodiseases

MedComm, Volume 7, Issue 11, November 2026.
Reactive astrocyte‐mediated pathogenic mechanisms in neurodegenerative diseases Schematic representation of key astrocytic pathways contributing to pathology in the pathogenesis of AD, PD, ALS, and HD. In AD, astrocytes exhibit Aβ plaque‐associated activation characterized by GFAP/S100β upregulation, accompanied by impaired EAAT2‐mediated glutamate ...
