Chronic immune response dysregulation in MDS pathogenesis

Abstract

Chronic innate immune signaling in hematopoietic cells is widely described in myelodysplastic syndromes (MDS), and innate immune pathway activation, predominantly via pattern recognition receptors, increases the risk of developing MDS. An inflammatory component to MDS has been reported for many years, but only recently has evidence supported a more direct role of chronic innate immune signaling and associated inflammatory pathways in the pathogenesis of MDS. Here we review recent findings and discuss relevant questions related to chronic immune response dysregulation in MDS.

  • Human MDS HSPCs show significant innate immune system dysregulation and resistance to the pro-proliferative effects of inflammation.

    “Human myelodysplastic syndrome (MDS) HSPCs have shown significant innate immune system dysregulation and resistance to the pro-proliferative effects of inflammation [69,80,81].”

    From Clonal hematopoiesis and inflammation – the perpetual cycle (2023) · cites this paper as [80]

    The section “Expression of immune-related genes in MDS hematopoietic stem/progenitor cells” says innate immune-related gene dysregulation is common in MDS HSPCs. The cited paper does not establish that MDS HSPCs resist inflammation’s pro-proliferative effects; its “Activation of immune receptors in MDS” section instead describes increased proliferation after TLR stimulation in human HSPCs generally, without specifying MDS HSPCs.

  • Dysregulated inflammatory signaling has emerged as a key partner alongside oncogenic mutations in the development and/or progression of hematological malignancy.

    “Dysregulated inflammatory signaling has emerged as a key partner alongside oncogenic mutations in the development and/or progression of hematological malignancy (Barreyro et al., 2018; Pietras, 2017).”

    From PU.1 enforces quiescence and limits hematopoietic stem cell expansion during inflammatory stress (2021) · cites this paper as Barreyro et al., 2018

    The Introduction and Conclusions identify chronic innate immune signaling as a contributor to MDS pathogenesis, and the section on innate immune signaling and clonal hematopoiesis describes proposed routes linking inflammatory signaling and somatic mutations. The paper focuses on MDS rather than hematological malignancies generally, and its Conclusions leave how immune signaling cooperates with genetic defects as an open question. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Chronic inflammation, often associated with increased IL-1 activity, is a common phenotype in individuals at risk for hematological malignancy, which can be related to several preexisting factors, including aging/tissue decline, genotoxin exposure, metabolic dysfunction, and/or autoimmune disease.

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.
