Interplay Among Synaptic Glutamate Release and Excitotoxicity: Neuronal Damage and Graphene-Based Materials Related...

Area of Science:

• Neuroscience
• Nanotechnology
• Biomedical Engineering

Background:

• Excitotoxicity, driven by excessive glutamate receptor stimulation, is a key pathological process in central nervous system disorders.
• Mechanisms include ionic dysregulation, mitochondrial dysfunction, oxidative stress, and impaired glutamate clearance, contributing to neuronal death.
• Excitotoxicity is a hallmark of neurodegenerative diseases like Alzheimer's, Parkinson's, and Huntington's disease, and ischemic stroke.

Purpose of the Study:

• To explore the potential of graphene-based materials (GBMs) as a novel therapeutic strategy for neuroprotection against excitotoxic injury.
• To investigate the neuromodulatory capacity of GBMs, particularly small graphene oxide nanosheets, in targeting pathological glutamatergic activity.

Main Methods:

• Review of recent advances in nanotechnology and GBMs for neural applications.
• Analysis of the physicochemical properties of GBMs and their interaction with neural tissue.
• Examination of studies investigating the effects of GBMs on glutamate transmission and neuroinflammation.

Main Results:

• GBMs possess unique properties suitable for neural interfacing, regenerative scaffolds, and drug delivery.
• Small graphene oxide nanosheets demonstrate the ability to downregulate glutamate release.
• GBMs exhibit anti-inflammatory and neuroprotective effects, mitigating excitotoxic injury.

Conclusions:

• GBMs represent a promising class of neuromodulatory tools for treating excitotoxicity.
• Further preclinical and translational research is warranted to develop GBM-based therapies for neurodegenerative conditions.
