The Association of Tau With Mitochondrial Dysfunction in Alzheimer’s Disease

Abstract

Increasing evidence suggests that abnormally hyperphosphorylated tau plays a vital role in the pathogenesis of Alzheimer's disease (AD). Mitochondrial dysfunction also has a recognized role in the pathophysiology of AD. In recent years, mitochondrial dysfunction has been strongly associated with tau pathology in AD. Overexpression of hyperphosphorylated and aggregated tau appears to damage the axonal transport, leading to abnormal mitochondrial distribution. In addition, pathological tau impairs mitochondrial dynamics by regulating mitochondrial fission/fusion proteins, and further causes mitochondrial dysfunction and neuronal damage. Moreover, mitochondrial dysfunction is also involved in promoting tau pathology in AD. In this article, we evaluate the relationship between phosphorylated tau and mitochondrial dysfunction in AD.

  • Decrease in Δψm has been observed in several in vitro and in vivo AD models.

    “A decrease in Δψm (or mitochondrial depolarization) has been observed in several in vitro and in vivo AD models [65,66]”

    From Apoe4 and Alzheimer’s Disease Pathogenesis—Mitochondrial Deregulation and Targeted Therapeutic Strategies (2023) · cites this paper as [66]

    The ‘Tau pathology and mitochondrial dysfunction in AD’ section reports depolarized mitochondrial membrane potential in a triple-transgenic AD mouse model and impaired membrane potential associated with truncated tau. It also discusses cell-culture studies, but does not clearly establish decreased membrane potential across several in vitro and in vivo AD models. No page number is available in our copy.

  • Aberrant tau phosphorylation and aggregation promote neuronal and synaptic damage, leading to cognitive decline in AD, through alterations in mitochondrial localization, imbalance in fusion/fission, ATP synthesis, ROS production and mitochondrial depolarization.

    “Through alterations in mitochondrial localization in neurons, imbalance in fusion and fission processes and in ATP synthesis, ROS production and mitochondrial depolarization, aberrant tau phosphorylation and aggregation promote neuronal and synaptic damage, leading to cognitive decline in AD [66].”
  • Tau hyperphosphorylation and aggregation have been related to impairment of mitochondrial dynamics, namely axonal transport and bioenergetics.

    “Tau hyperphosphorylation and aggregation have been related to the impairment of mitochondrial dynamics, namely axonal transport and bioenergetics.”
  • Although Alzheimer's disease has complex multifactorial effects, oxidative stress is key to the initiation of the pathophysiological process in cholinergic neurons.

    “Although AD has complex multifactorial, effects OS is key to the initiation of the pathophysiological process in cholinergic neurons [107,108,109].”

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.
