The role of metallobiology and amyloid-β peptides in Alzheimer's disease

Abstract

The biggest risk factor for Alzheimer's disease is the process of ageing, but the mechanisms that lead to the manifestation of the disease remain to be elucidated. Why age triggers the disease is unclear but an emerging theme is the inability for a cell to efficiently maintain many key processes such as energy production, repair, and regenerative mechanisms. Metal ions are essential to the metabolic function of every cell. This review will explore the role and reported changes in metal ions in Alzheimer disease, particularly the brain, blood and cerebral spinal fluid, emphasizing how iron, copper and zinc may be involved through the interactions with amyloid precursor protein, the proteolytically cleaved peptide amyloid-beta (Aβ), and other related metalloproteins. Finally, we explore the monomeric makeup of possible Aβ dimers, what a dimeric Aβ species from Alzheimer's disease brain tissue is likely to be composed of, and discuss how metals may influence Aβ production and toxicity via a copper catalyzed dityrosine cross-link.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • High concentrations of zinc, copper, and iron are present in the insoluble amyloid plaques and neurofibrillary tangles characteristic of Alzheimer's disease.

    “High concentrations of zinc, copper, and iron are present in the insoluble amyloid plaques and neurofibrillary tangles characteristic of Alzheimer’s disease.”
  • Focal accumulation of zinc, copper, and iron might deprive other brain tissues of these essential metals, leading to aberrant neuronal function.

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.
