  • The gut microbiota is required for microglial activation in 5xFAD mice.

    “Similarly, the gut microbiota is required for microglial activation in 5xFAD mice.203–205”
  • 5-month antibiotics treatment alleviated AD pathologies and microglial activation in 6.5-month-old 5xFAD mice by inhibiting C/EBPβ/AEP signaling.

    “Moreover, 5-month antibiotics treatment alleviated AD pathologies and microglial activation in 6.5-month-old 5xFAD mice by inhibiting CCAAT/enhancer binding protein β/asparagine endopeptidase (C/EBPβ/AEP) signaling.204”
  • Chronic antibiotic treatment subdues C/EBPβ/AEP signaling, diminishes amyloidogenic processes, and rescues cognitive functions in an Alzheimer's disease model.

    “Chronic antibiotic treatment subdued C/EBPβ/AEP signaling and diminished amyloidogenic processes, rescuing cognitive functions.”
  • In a 5xFAD mouse model of Alzheimer's disease, gut dysbiosis is positively associated with C/EBPβ/AEP messaging in the brain, concomitant with age-related progression of disease severity.

    “A recent study demonstrated that gut dysbiosis was positively associated with C/EBPβ/AEP messaging in the brain of a 5xFAD mouse model of Alzheimer’s disease, concomitant with age-related progression of disease severity (501).”

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.
