Mitochondria are primary sites of reactive oxygen species formation that causes progressive damage to mitochondrial DNA and proteins in parallel to intralysosomal lipofuscin accumulation. There is amassing evidence that several various mechanisms may contribute to age-related accumulation of damaged mitochondria following initial oxidative injury. Such mechanisms may include clonal expansion of defective mitochondria, decreased propensity of altered mitochondria to become autophagocytosed (due to mitochondrial enlargement or decreased membrane damage associated with weakened respiration), suppressed autophagy because of heavy lipofuscin loading of lysosomes, and decreased efficiency of Lon protease. © 2004 Elsevier Inc.
