Soluble Aβ oligomer production and toxicity

Abstract

For nearly 100 years following the first description of this neurological disorder by Dr Alois Alzheimer, amyloid plaques and neurofibrillary tangles have been hypothesized to cause neuronal loss. With evidence that the extent of insoluble, deposited amyloid poorly correlated with cognitive impairment, research efforts focused on soluble forms of Aβ, also referred as Aβ oligomers. Following a decade of studies, soluble oligomeric forms of Aβ are now believed to induce the deleterious cascade(s) involved in the pathophysiology of Alzheimer's disease. In this review, we will discuss our current understanding about endogenous oligomeric Aβ production, their relative toxicity in vivo and in vitro, and explore the potential future directions needed for the field.

  • In FAD-Tg mice, soluble oAβ reduces synaptic plasticity.

    “reduces synaptic plasticity”

    From APOE4-specific Changes in Aβ Accumulation in a New Transgenic Mouse Model of Alzheimer Disease (2012) · cites this paper as [52]

    The Toxicity of Oligomeric Aβ Assemblies section (page unavailable) says oligomeric Aβ can impair synaptic plasticity. It also discusses Aβ oligomers and deficits in transgenic mouse models, but the passages do not establish that soluble oligomers reduced synaptic plasticity specifically in those mice; the mouse-model findings described concern cognition or neuronal function. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In FAD-Tg mice, soluble oAβ suppresses synaptic function.

    “In FAD-Tg mice, soluble oA␤ suppresses synaptic function”

    From APOE4-specific Changes in Aβ Accumulation in a New Transgenic Mouse Model of Alzheimer Disease (2012) · cites this paper as [52]

    In ‘II. Toxicity of Oligomeric Aβ Assemblies’ (page unavailable), the review reports that soluble Aβ oligomers inhibit LTP, a measure of synaptic plasticity. It also describes Aβ-induced neuronal and cognitive deficits in APP-transgenic mice, but does not clearly establish that soluble oligomers suppress synaptic function specifically in those mice. (LLM, conf=0.80)

    Experimental — accuracy not yet measured
  • In FAD-Tg mice, soluble oAβ impairs learning and memory.

    “impairs learning and memory (52).”

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.
