Mitochondrial dysfunction as a driver of chronic pain: New insights and therapeutic prospects

Area of Science:

• Neuroscience
• Cell Biology
• Biochemistry

Background:

• Chronic pain affects millions globally and is often resistant to current treatments.
• Mitochondrial dysfunction is increasingly recognized as a key factor in pain chronification.
• Understanding these cellular mechanisms is crucial for developing effective pain therapies.

Purpose of the Study:

• To review current knowledge on how mitochondrial impairment contributes to chronic pain.
• To explore the role of bioenergetic failure, oxidative stress, and neuroinflammation in pain.
• To summarize mitochondria-targeted therapeutic strategies for pain management.

Main Methods:

• Literature review synthesizing research on mitochondrial dysfunction and pain.
• Analysis of cellular mechanisms including ATP depletion, oxidative stress, and mitophagy.
• Examination of therapeutic approaches targeting mitochondria.

Main Results:

• Mitochondrial dysfunction, including bioenergetic failure and impaired quality control, drives pain chronification.
• Energy deficits converge with oxidative stress, calcium overload, and neuroinflammation to increase neuronal excitability.
• Mitochondria-targeted therapies show efficacy in preclinical and clinical settings.

Conclusions:

• Mitochondrial dysfunction is a central mechanism in chronic pain development and persistence.
• Further research into biomarkers and neuro-glial interactions can advance precision pain medicine.
• Mitochondria-based therapies hold significant potential for managing chronic pain.
