Metal-associated amyloid-β species in Alzheimer's disease

Pithadia, Amit S, Lim, Mi Hee·2012·Current Opinion in Chemical Biology

Abstract

Highly concentrated metals such as Cu, Zn, and Fe are found in amyloid-β (Aβ) plaques within the brain of Alzheimer's disease (AD). In vitro and in vivo studies have suggested that metal binding to Aβ could facilitate Aβ aggregation and generate reactive oxygen species (ROS), which could contribute to the neuropathogenesis of AD. The connection between metal-Aβ interaction/reactivity and AD development, however, has not been clearly revealed owing to the complexity of the disease. In this review, metal-Aβ interaction/reactivity and its relation to neurotoxicity are briefly discussed. Additionally, our review illustrates the recent progress of small molecules, capable of targeting metal-Aβ species and modulating their interaction/reactivity, which could offer a promising approach to interrogate their role in AD.

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?

  • Recent efforts to control abnormal Aβ-metal interactions have focused on small molecules, bifunctional chelators (BFCs), that have binding affinity for both metal ions and Aβ aggregates.

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.
