Changes in macrophage transcriptome associate with systemic sclerosis and mediate GSDMA contribution to disease risk

Open access

Abstract

Objectives Several common and rare risk variants have been reported for systemic sclerosis (SSc), but the effector cell(s) mediating the function of these genetic variants remains to be elucidated. While innate immune cells have been proposed as the critical targets to interfere with the disease process underlying SSc, no studies have comprehensively established their effector role. Here we investigated the contribution of monocyte-derived macrophages (MDMs) in mediating genetic susceptibility to SSc. Methods We carried out RNA sequencing and genome-wide genotyping in MDMs from 57 patients with SSc and 15 controls. Our differential expression and expression quantitative trait locus (eQTL) analysis in SSc was further integrated with epigenetic, expression and eQTL data from skin, monocytes, neutrophils and lymphocytes. Results We identified 602 genes upregulated and downregulated in SSc macrophages that were significantly enriched for genes previously implicated in SSc susceptibility (P=5×10−4), and 270 cis-regulated genes in MDMs. Among these, GSDMA was reported to carry an SSc risk variant (rs3894194) regulating expression of neighbouring genes in blood. We show that GSDMA is upregulated in SSc MDMs (P=8.4×10−4) but not in the skin, and is a significant eQTL in SSc macrophages and lipopolysaccharide/interferon gamma (IFNγ)-stimulated monocytes. Furthermore, we identify an SSc macrophage transcriptome signature characterised by upregulation of glycolysis, hypoxia and mTOR signalling and a downregulation of IFNγ response pathways. Conclusions Our data further establish the link between macrophages and SSc, and suggest that the contribution of the rs3894194 risk variant to SSc susceptibility can be mediated by GSDMA expression in macrophages.

  • Patients with systemic sclerosis have higher expression of GRB10 in monocytes.

    “GRB10 has been associated with a subtype of systemic sclerosis (lcSSc); patients with systemic sclerosis have higher expression of GRB10 in monocytes67,68.”

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as [68]

    The Results (Differential expression analysis of SSc and control MDMs; page unavailable) identify GRB10 among genes upregulated in patients with systemic sclerosis. However, the cells studied were monocyte-derived macrophages, not monocytes, so the cited paper does not establish higher GRB10 expression in monocytes. (LLM, conf=0.87)

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as [68]

    The Results (Differential expression analysis of SSc and control MDMs; page unavailable) state that GRB10 had previously been associated with SSc subphenotypes by GWAS. The passage does not identify the associated subtype as limited cutaneous SSc (lcSSc), so it supports the general association but not that specificity. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • To get realistic estimates for effect sizes (fold changes), data sets from FACS sorted bulk RNA-seq studies were taken53,54.

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.
