Excitotoxicity as a Target Against Neurodegenerative Processes

Area of Science:

• Neuroscience
• Pathology
• Pharmacology

Background:

• Neurodegenerative diseases are a growing global health concern, particularly in aging populations.
• Excitotoxicity, neuronal damage from excessive glutamate, is a significant contributor to neurodegeneration.
• Current treatments like memantine offer limited benefits, highlighting the need for novel therapeutic strategies.

Purpose of the Study:

• To review the molecular mechanisms underlying excitotoxic cell death.
• To provide an updated overview of preclinical and clinical research targeting excitotoxicity in neurodegenerative diseases.
• To identify potential therapeutic strategies for halting or curing neurodegenerative conditions.

Main Methods:

• Literature review of molecular mechanisms of excitotoxicity.
• Comprehensive analysis of preclinical studies on excitotoxicity-targeting agents.
• Evaluation of clinical trial data for therapies aimed at neuroprotection.

Main Results:

• Glutamate dysregulation disrupts calcium homeostasis, leading to oxidative stress, mitochondrial dysfunction, and neuroinflammation.
• Preclinical studies show promise for various agents targeting excitotoxic pathways.
• Clinical evidence for effective neuroprotection remains limited, emphasizing ongoing research needs.

Conclusions:

• Excitotoxicity is a central mechanism in neurodegeneration, involving complex cellular pathways.
• Targeting excitotoxic mechanisms represents a promising therapeutic avenue.
• Further research and clinical trials are crucial for developing effective treatments for neurodegenerative diseases.
