Neuron-specific mitochondrial DNA deletion levels in sporadic Alzheimer's disease.

Abstract

Oxidative stress is implicated in the pathogenesis of neurodegenerative diseases, including sporadic Alzheimer´s disease (AD). Mitochondrial DNA (mtDNA) deletions are markers of oxidative damage and increase with age. To unravel the impact of mtDNA damage on AD development, we analyzed mtDNA deletion levels in diverse neuronal cell types of four brain… (More)
