Mitochondrial dysfunction in distal axons contributes to human immunodeficiency virus sensory neuropathy

Abstract excerpt

OBJECTIVE: Accumulation of mitochondrial DNA (mtDNA) damage has been associated with aging and abnormal oxidative metabolism. We hypothesized that in human immunodeficiency virus-associated sensory neuropathy (HIV-SN), damaged mtDNA accumulates in distal nerve segments, and that a spatial pattern of mitochondrial dysfunction contributes to the distal degeneration of sensory nerve fibers. METHODS: We measured...
