Abstract

Abstract Alzheimer’s disease (AD) is the most common form of dementia, characterized by accumulation of amyloid β (Aβ) and neurofibrillary tangles. Oxidative stress and inflammation are considered to play an important role in the development and progression of AD. However, the extent to which these events contribute to the Aβ pathologies remains unclear. We performed inter-species comparative gene expression profiling between AD patient brains and theAppNL-G-F/NL-G-Fand 3xTg-AD-H mouse models. Genes commonly altered inAppNL-G-F/NL-G-Fand human AD cortices correlated with the inflammatory response or immunological disease. Among them, expression of AD-related genes (C4a/C4b,Cd74,Ctss,Gfap,Nfe2l2,Phyhd1,S100b,Tf,Tgfbr2, andVim) was increased in theAppNL-G-F/NL-G-Fcortex as Aβ amyloidosis progressed with exacerbated gliosis, while genes commonly altered in the 3xTg-AD-H and human AD cortices correlated with neurological disease. TheAppNL-G-F/NL-G-Fcortex also had altered expression of genes (Abi3,Apoe,Bin2,Cd33,Ctsc,Dock2,Fcer1g,Frmd6,Hck,Inpp5D,Ly86,Plcg2,Trem2,Tyrobp) defined as risk factors for AD by genome-wide association study or identified as genetic nodes in late-onset AD. These results suggest a strong correlation between cortical Aβ amyloidosis and the neuroinflammatory response and provide a better understanding of the involvement of gender effects in the development of AD.

  • PLCG2 mRNA upregulation has been reported in transgenic mice carrying early-AD mutations or overexpressing human tau.

    “and in transgenic mice carrying mutations associated with early AD (APP KM670/671 NL, PNSEN1 M146V) or overexpressing the human tau-4R/2N isoform (P301L) [34, 35].”

    From Alzheimer’s disease phospholipase C-gamma-2 (PLCG2) protective variant is a functional hypermorph (2019) · cites this paper as [34]

    The Results report significantly increased Plcg2 expression in the cortex of App NL-G-F/NL-G-F mice carrying pathogenic App mutations. But this is an App knock-in model, not the APP/PSEN1/MAPT transgenic model described in the citing sentence. For that 3xTg-AD-H model, the Results report only Trem2—not Plcg2—as significantly increased. (LLM, conf=0.88)

  • Some studies have identified selected overlaps in expression changes between AD mouse models and human brains.

    “Although some studies have identified selected overlaps in expression changes between AD mouse models and human brains (Bennett et al., 2018; Castillo et al., 2017; Mostafavi et al., 2018; Neuner et al., 2019; Rojo et al., 2017), other studies have questioned the overall degree of conservation (Burns et al., 2015; Galatro et al., 2017; Hargis and Blalock, 2017).”
  • Another study found an upregulation of INPP5D RNA expression in both human AD patients and an App knock-in mouse model.

    “Another study similarly found an upregulation of INPP5D RNA expression in both human AD patients and an App knock-in mouse model [170].”
  • Comparative gene expression profiling of known genetic risk factors in AD revealed an increase of PLCG2 gene expression in the cortex of AppNL-G-F/NL-G-F mice.

    “Comparative gene expression profiling of known genetic risk factors in AD revealed an increase of PLCG2 gene expression in the cortex of AppNL-G-F/NL-G-F mice (165).”
  • LILRB4 orthologues are increased with amyloid deposition and specifically associated with amyloid plaques.

    “LILRB4 (leukocyte immunoglobulin-like receptor, subfamily B, member 4), orthologues have also been shown to be increased with amyloid deposition and specifically associated with amyloid plaques (Wirz et al., 2013; Kamphuis et al., 2016; Castillo et al., 2017).”

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.
