Abstract

The only recognized genetic determinant of the common forms of Alzheimer's disease (AD) is the epsilon 4 allele of the apolipoprotein E gene (APOE). To identify new candidate genes, we recently performed transcriptomic analysis of 2741 genes in chromosomal regions of interest using brain tissue of AD cases and controls. From 82 differentially expressed genes, 1156 polymorphisms were genotyped in two independent discovery subsamples (n=945). Seventeen genes exhibited at least one polymorphism associated with AD risk, and following correction for multiple testing, we retained the interleukin (IL)-33 gene. We first confirmed that the IL-33 expression was decreased in the brain of AD cases compared with that of controls. Further genetic analysis led us to select three polymorphisms within this gene, which we analyzed in three independent case-control studies. These polymorphisms and a resulting protective haplotype were systematically associated with AD risk in non-APOE epsilon 4 carriers. Using a large prospective study, these associations were also detected when analyzing the prevalent and incident AD cases together or the incident AD cases alone. These polymorphisms were also associated with less cerebral amyloid angiopathy (CAA) in the brain of non-APOE epsilon 4 AD cases. Immunohistochemistry experiments finally indicated that the IL-33 expression was consistently restricted to vascular capillaries in the brain. Moreover, IL-33 overexpression in cellular models led to a specific decrease in secretion of the A beta(40) peptides, the main CAA component. In conclusion, our data suggest that genetic variants in IL-33 gene may be associated with a decrease in AD risk potentially in modulating CAA formation.

  • Previously, IL-33 was identified as an AD risk gene and its level was decreased in the brains of LOAD patients.

    “Previously, IL-33 was identified as an AD risk gene and its level was decreased in the brains of LOAD patients (53).”

    From The effect of Abi3 locus deletion on the progression of Alzheimer’s disease-related pathologies (2023) · cites this paper as [53]

    The Results (‘In depth analysis of the IL-33 gene’; page unavailable) report lower IL-33 mRNA expression in AD brains than controls, and the paper identifies IL-33 as a candidate AD risk gene. However, the Methods (‘Brain samples’; page unavailable) describe samples from both early- and late-onset AD patients; the reported expression decrease is not shown specifically for LOAD patients. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • IL-33 expression is reduced in the brains of patients with AD.

    “IL-33 expression is reduced in the brains of patients with AD (15), and sST2 is increased in the serum of patients with MCI, as demonstrated in the present study (Fig. 1A).”
  • Observations in the murine AD model could be extrapolated to humans.

    “Indeed, genetic studies have linked IL-33/ST2 single nucleotide polymorphisms to clinical AD (15,51), suggesting that our observations in the murine AD model could be extrapolated to humans.”

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.
