Abstract

We have generated a novel transgenic mouse model on a C57BL/6J genetic background that coexpresses KM670/671NL mutated amyloid precursor protein and L166P mutated presenilin 1 under the control of a neuron-specific Thy1 promoter element (APPPS1 mice). Cerebral amyloidosis starts at 6-8 weeks and the ratio of human amyloid (A)beta42 to Abeta40 is 1.5 and 5 in pre-depositing and amyloid-depositing mice, respectively. Consistent with this ratio, extensive congophilic parenchymal amyloid but minimal amyloid angiopathy is observed. Amyloid-associated pathologies include dystrophic synaptic boutons, hyperphosphorylated tau-positive neuritic structures and robust gliosis, with neocortical microglia number increasing threefold from 1 to 8 months of age. Global neocortical neuron loss is not apparent up to 8 months of age, but local neuron loss in the dentate gyrus is observed. Because of the early onset of amyloid lesions, the defined genetic background of the model and the facile breeding characteristics, APPPS1 mice are well suited for studying therapeutic strategies and the pathomechanism of amyloidosis by cross-breeding to other genetically engineered mouse models.

  • Activated microglia surround amyloid plaques in human Alzheimer's disease and mouse Aβ amyloidosis models.

    “Activated microglia surround amyloid plaques in the brains of both human patients with AD and mouse models of Aβ amyloidosis13,15,21,22.”

    From Deletion of SPI1 in microglia exacerbates amyloid pathology by impairing microglial response in Alzheimer’s disease models (2026) · cites this paper as [13]

    The Amyloid-associated neuroinflammation and pathology section and Fig. 4 caption report activated, hypertrophic microglia clustered around amyloid plaques in APPPS1-21 mice (page not provided). The paper compares mouse plaque appearance with human AD plaques, but the passages do not establish that activated microglia surround plaques in human patients. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • A previous report found no sex-dependent differences in Aβ accumulation in the APPPS1-21 mouse model.

    “although a previous report demonstrated no sex-dependent differences in Aβ accumulation in this APPPS1–21 mouse model13”

    From Deletion of SPI1 in microglia exacerbates amyloid pathology by impairing microglial response in Alzheimer’s disease models (2026) · cites this paper as [13]

    The Cerebral amyloidosis section reports that male and female APPPS1-21 mice did not differ statistically in Aβ levels or amyloid load at 1–2 months of age. The sex comparison was limited to those early ages, so it does not establish an absence of sex-dependent differences in Aβ accumulation generally. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • There is no sex-dependent difference in the phenotypes of APP(Swe)/PS1(L166P) mice.

    “A previous report demonstrated no sex-dependent difference in the phenotypes of APP(Swe)/PS1(L166P) mice8.”

    From Effects of SPI1-mediated transcriptome remodeling on Alzheimer's disease-related phenotypes in mouse models of Aβ amyloidosis (2024) · cites this paper as [8]

    The Cerebral amyloidosis section reports that Aβ levels and amyloid load in 1- and 2-month-old male APPPS1-21 mice were not statistically different from females. That supports no sex difference in those measured early amyloid outcomes, but the paper says the analysis was mainly restricted to females and does not establish no sex-dependent difference across the mice’s phenotypes. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Reactive gliosis, encompassing microgliosis and astrogliosis, are prevalent neuropathological hallmarks in the brains of both human AD and mouse models of Aβ amyloidosis.

    “The reactive gliosis, encompassing microgliosis and astrogliosis, are prevalent neuropathological hallmarks observed in the brains of both human AD and mouse models of Aβ amyloidosis8,15,16.”

    From Effects of SPI1-mediated transcriptome remodeling on Alzheimer's disease-related phenotypes in mouse models of Aβ amyloidosis (2024) · cites this paper as [8]

    The ‘Amyloid-associated neuroinflammation and pathology’ section reports microgliosis and simultaneous astrocytosis after plaques appeared in APPPS1-21 mice. The paper does not establish that both are prevalent hallmarks in human AD brains, so the human part of the attributed claim is unsupported by this source. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • There is no sex effect in the APP/PS1 experimental group.

    “Because it has been known that there is no sex effect in this experimental group8, male and female mice were combined for statistical analyses.”

    From Effects of SPI1-mediated transcriptome remodeling on Alzheimer's disease-related phenotypes in mouse models of Aβ amyloidosis (2024) · cites this paper as [8]

    The Cerebral amyloidosis section reports that Aβ levels and amyloid load in male APPPS1-21 mice at 1–2 months were not statistically different from those in females. That supports a lack of detected sex difference for those measures and ages, but not the broader assertion that there is no sex effect in the experimental group generally. (LLM, conf=0.87)

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.
