Copper, Cuproptosis, and Neurodegenerative Diseases.

Area of Science:

• Biochemistry and Molecular Biology
• Environmental Science
• Neuroscience

Background:

• Copper is an essential micronutrient, acting as a cofactor in metabolic enzymes and redox reactions.
• Copper homeostasis is critical, as both deficiency and excess disrupt cellular functions.
• Environmental copper contamination poses significant human health and ecological risks.

Purpose of the Study:

• To review the dual role of copper as an essential nutrient and a toxicant.
• To explore the newly identified cell death pathway, cuproptosis, and its implications.
• To discuss the link between copper, cuproptosis, and neurodegenerative diseases.

Main Methods:

• Literature review of studies on copper metabolism, homeostasis, and toxicity.
• Analysis of research on cuproptosis mechanisms and its relation to lipoylated enzymes.
• Examination of studies linking copper dysregulation to neurodegenerative disorders.

Main Results:

• Copper's essentiality in cellular respiration and metabolism is confirmed.
• Cuproptosis, a copper-dependent cell death, is identified as a potential therapeutic target.
• Environmental copper accumulation, particularly in agricultural soils, presents toxicity concerns.

Conclusions:

• Copper's intricate role in cellular health and disease necessitates careful management.
• Targeting cuproptosis offers a promising avenue for treating neurodegenerative conditions.
• Sustainable practices like phytoremediation are crucial for mitigating environmental copper contamination.
