Redox active metals in neurodegenerative diseases

Area of Science:

• Neuroscience
• Biochemistry
• Cellular Biology

Background:

• Copper (Cu) and iron (Fe) are essential redox-active metals crucial for fundamental brain functions.
• Cellular pathways involving neurotransmitter synthesis, release, and protein turnover rely on tightly regulated Cu and Fe homeostasis.
• Dysregulation of Cu and Fe homeostasis is implicated in neurodegenerative conditions.

Purpose of the Study:

• To review the evidence linking copper and iron dyshomeostasis to neurodegeneration.
• To examine preclinical and clinical studies on pharmacological interventions for Cu and Fe abnormalities in neurodegenerative diseases.

Main Methods:

• Literature review of scientific evidence.
• Analysis of studies on Alzheimer's disease (AD), Parkinson's disease (PD), and Amyotrophic lateral sclerosis (ALS).

Main Results:

• Perturbations in copper and iron regulation are observed in neurodegenerative diseases.
• Pharmacological interventions targeting Cu and Fe abnormalities show promise in preclinical and clinical settings.

Conclusions:

• Restoring copper and iron balance is a potential therapeutic strategy for neurodegenerative disorders.
• Further research into Cu and Fe dyshomeostasis may yield novel treatments for AD, PD, and ALS.
