Abstract

Murine transgenic models of Alzheimer's disease (Tg-AD) have been useful to analyze the contribution of β-amyloid precursor protein (βAPP), Aβ42 peptide deposition, and the proinflammatory mechanisms that characterize Alzheimer-type neuropathology. In this report, we have studied the levels of βAPP, Aβ40 and Aβ42 peptide, as well as the innate immune and inflammatory response-regulator complement factor H in the brain and retina in four different Tg-AD models including Tg2576, PSAPP, 3xTg-AD, and 5xFAD. Aged, symptomatic 5xFAD mice showed the highest retinal abundance of Aβ42 peptides and the highest deficits in complement factor H. This may be a useful model to study the mechanisms of amyloid-mediated inflammatory degeneration. The superior colliculus and retina obtained from late-stage Alzheimer's disease revealed upregulated amyloidogenic and inflammatory signaling along the anteroposterior axis of the retinal-primary visual cortex pathway.

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.
