- Mitochondrial dysfunction is a key feature of neurodegenerative diseases, linked to impaired mitophagy and damaged mitochondria accumulation.
- The study explores the association between mitochondrial DNA (mtDNA) variations and pS65-Ub levels in Lewy body disease (LBD) brains.
- No significant association was found between individual mtDNA haplogroups and pS65-Ub levels after multiple testing corrections.
- mtDNA haplogroup V showed a nominal association with pS65-Ub, but this was not replicated in an independent cohort.
- Findings suggest mitochondrial damage in LBD is not primarily driven by major mtDNA determinants but by complex, multilayered mitochondrial function perturbations.
- Future research should focus on single-cell analyses and larger cohorts integrating multi-omics datasets to validate findings and discover biomarkers for mitochondrial dysfunction in neurodegeneration.
