Abstract

Immunogenetic Variation: Many genetic variants have been implicated in disease but their effects in function across tissues and cell-types remain to be resolved. Raj et al. (p. 519 ) present an analysis of expression quantative trait loci (eQTL) measuring messenger RNA levels and examined correlations between genotypes and gene expression in purified monocytes and T cells in healthy individuals of European, African, and Asian descent. Most, but not all, of the eQTLs and their effects on expression were shared between the populations, as well as a substantial proportion between the cell types. Links were found with disease-associated variants and loci that previous genome-wide analyses have implicated in neurodegenerative and autoimmune diseases.

  • 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 [21]

    The paper reports that AD susceptibility alleles are enriched for monocyte-specific effects and suggests that monocytes may be proxies for resident microglia (Abstract; page unavailable). This supports a genetic link to myeloid cells, but it does not establish an AD-associated network of microglial-expressed genes or an epigenetic association specific to that network. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Enrichment for MS susceptibility loci is observed not only in T cells but also in B cells.

    “An important finding is that the enrichment is observed not only in immune cells that have long been studied in MS, e.g. T cells, but also in B cells whose role has emerged more recently.(25)”

    From Multiple sclerosis genomic map implicates peripheral immune cells and microglia in susceptibility (2019) · cites this paper as [25]

    The passage discussing disease-associated cis-eQTLs (indexed as Abstract; page unavailable) reports a preponderance of T-cell-specific effects among multiple-sclerosis susceptibility alleles. The study profiled T cells and monocytes, not B cells, so it does not support the claimed enrichment in B cells. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Multiple sclerosis genome-wide association study loci are enriched for expression quantitative trait loci in multiple tissues, supporting the idea that much risk is due to changes to gene regulation.

    “MS GWAS loci are also enriched for expression quantitative trait loci (eQTL) in multiple tissues,46, 57 supporting the idea that much risk is due to changes to gene regulation.”

    From Genome‐wide association studies of multiple sclerosis (2018) · cites this paper as [57]

    The paper reports significant cis-eQTL enrichment among autoimmune-disease GWAS variants in monocytes and/or T cells, and identifies multiple sclerosis susceptibility alleles as having predominantly T-cell-specific regulatory effects (Abstract; page unavailable). It does not establish that MS GWAS loci specifically are enriched for eQTLs in multiple tissues, or quantify how much MS risk is due to regulatory changes. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • AD-risk alleles are polarized for cis-eQTL effects in monocytes.

    “Further, AD-risk alleles are polarized for cis-expression quantitative trait locus (cis-eQTL) effects in monocytes21.”
  • Many elements of innate immunity, such as natural killer cells and dendritic cells, display strong enrichment for MS susceptibility genes.

    “Furthermore, while the adaptive immune system has been proposed to play a predominant role in MS onset,(26) we now demonstrate that many elements of innate immunity, such as natural killer (NK) cells and dendritic cells also display strong enrichment for MS susceptibility genes.”

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.
