Description

The abstract identifies mitochondrial oxidative stress as playing a ‘vital role’ in generating cytoplasmic free mtDNA but doesn’t explain the mechanistic pathway. Understanding this process is crucial for developing targeted interventions to prevent mtDNA leakage and subsequent neuroinflammation.
