Abstract

We used a protein quantitative trait analysis in monocytes from 226 individuals to evaluate cross-talk between Alzheimer loci. The NME8 locus influenced PTK2B and the CD33 risk allele led to greater TREM2 expression. There was also a decreased TREM1/TREM2 ratio with a TREM1 risk allele, decreased TREM2 expression with CD33 suppression and elevated cortical TREM2 mRNA expression with amyloid pathology.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The findings strengthen the growing evidence linking AD to a network of genes expressed in microglia.

    “These results reinforce the emerging genetic and epigenetic association between AD and a network of microglial expressed genes2,5,17–21”

    From A common haplotype lowers PU.1 expression in myeloid cells and delays onset of Alzheimer's disease (2017) · cites this paper as [20]

    The paper’s introductory passage (page unavailable) links AD susceptibility variants to innate immune genes and identifies an AD-associated microglial transcriptomic network. Its own results examine interactions among AD loci chiefly in monocytes, supporting the broader link in the claim. The cited paper does not report an epigenetic association, which is also asserted in the verbatim citing sentence. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Human AD risk gene variants linked to monocytes include TREM2 and CD33; CD33 is linked to diminished Aβ internalization by peripheral monocytes.

    “Several human AD risk gene variants have been linked to monocytes, including those related with TREM2 and CD33 [34, 52], the latter of which is linked to diminished Aβ internalization by peripheral monocytes [34].”

    From Microglia and monocytes in inflammatory CNS disease: integrating phenotype and function (2022) · cites this paper as [52]

    The paper’s indexed text (section labeled Abstract; no page supplied) identifies TREM2 and CD33 as AD susceptibility loci and reports effects of a CD33 risk allele in human monocytes. Its CD33 suppression results concern TREM2 surface expression, not Aβ internalization; searches for Aβ uptake or internalization in peripheral monocytes found no supporting passage. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Trem2+ monocytes can be detected in blood samples.

    “As Trem2+ monocytes can be detected in blood samples,77”
  • Genes expressed in myeloid cells display abnormal patterns of chromatin modification in AD mouse models and human samples.

    “At the epigenetic level, genes expressed in myeloid cells display abnormal patterns of chromatin modification in AD mouse models and human samples18–20.”

    From A common haplotype lowers PU.1 expression in myeloid cells and delays onset of Alzheimer's disease (2017) · cites this paper as [20]

    The Abstract reports protein-expression and genetic-association findings in human monocytes, not abnormal chromatin modification in myeloid-cell genes. Searches for chromatin modification and histone changes in AD mouse models and human samples found no passage addressing the claim in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Cases received a diagnosis of dementia of the Alzheimer's type based on NINCDS-ADRDA criteria.

    “Cases were diagnosed with dementia of the Alzheimer’s type (DAT) according to the NINCDS-ADRDA20.”

    From A common haplotype lowers PU.1 expression in myeloid cells and delays onset of Alzheimer's disease (2017) · cites this paper as [20]

    The Online Methods describe ROS/MAP participants as cognitively normal at enrollment and receiving annual clinical evaluations, but do not state how Alzheimer’s dementia cases were diagnosed. Searches for NINCDS-ADRDA and dementia diagnosis found no passage specifying those criteria; the passages provide no page numbers. (LLM, conf=0.72)

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.
