Abstract

Mitochondria are uniquely poised to play a pivotal role in neuronal cell survival or death because they are regulators of both energy metabolism and cell death pathways. Extensive literature exists supporting a role for mitochondrial dysfunction and oxidative damage in the pathogenesis of Alzheimer's disease. This review discusses evidence indicating that mitochondrial dysfunction has an early and preponderant role in Alzheimer's disease. Furthermore, the link between mitochondrial dysfunction and autophagy in Alzheimer's disease is also discussed. As a result of insufficient digestion of oxidatively damaged macromolecules and organelles by autophagy, neurons progressively accumulate lipofuscin that could exacerbate neuronal dysfunction. Since autophagy is the major pathway involved in the degradation of protein aggregates and defective organelles, an intense interest in developing autophagy-related therapies is growing among the scientific community. The final part of this review is devoted to discuss autophagy as a potential target of therapeutic interventions in Alzheimer's disease pathophysiology.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Metal ions specifically zinc and copper may bind to the Aβ plaque and produce reactive oxygen species (ROS).

    “Metal ions specifically zinc and copper may bind to the Aβ plaque and produce ROS.”
  • ROS produced brings about oxidative change in the Aβ peptide itself making its removal difficult and also causes lipid and protein oxidation of the cell membrane making it permeable and hence susceptible to degeneration.

    “ROS thus produced brings about oxidative change in the Aβ peptide itself making its removal difficult and also cause lipid and protein oxidation of the cell membrane making it permeable and hence susceptible to degeneration [24, 29, 30].”
  • Aβ peptides can induce ROS production from mitochondria, leading to release of cytochrome c and apoptosis-inducing factor, thereby driving mitochondrial dysfunction, cell apoptosis, and neuronal loss.

    “Aβ peptides can induce ROS production from mitochondria, leading to release of cytochrome c and apoptosis-inducing factor, thereby driving mitochondrial dysfunction, cell apoptosis and neuronal loss [97, 100].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
