Abstract

Infections and inflammation trigger neutrophilias that are supported by a hematopoietic program of accelerated granulopoiesis known as emergency granulopoiesis. The intrinsic factors that drive reactive neutrophilias and emergency granulopoiesis have been inferred but not demonstrated. Here, we show that alum cannot elicit reactive neutrophilias in IL-1R type I (IL-1RI)−/− mice, whereas other inflammatory responses, including eosinophilia and Ab production, remain intact. Analysis of this specific impairment revealed an unanticipated role for IL-1RI in supporting increased proliferation by granulocyte/macrophage progenitors and, surprisingly, multipotent progenitors and hematopoietic stem cells (HSC). Indeed, HSC and multipotent progenitor proliferative responses were most suppressed in IL-1RI−/− mice, suggesting a critical role for their proliferation in inflammatory granulopoiesis. Whereas IL-1 drives increased HSC proliferation directly in vitro, IL-1RI expression by radiation-resistant host cells was both necessary and sufficient for alum-induced HSC, multipotent progenitor, and granulocyte/macrophage progenitor proliferation and reactive neutrophilias in radiation chimeric mice. Thus, IL-1 plays a necessary, but indirect, role in the support of alum-induced neutrophilias by expanding both pluripotent and myeloid progenitor compartments to accelerate granulopoiesis.

  • IL-1 can stimulate HSC proliferation, driving their myeloid differentiation at the expense of self-renewal, thus eroding their repopulating capacity.

    From Aging drives <i>Tet2</i> <i>+/−</i> clonal hematopoiesis via IL-1 signaling (2023) · cites this paper as [49]

    The Discussion (page not supplied) reports that HSC proliferate in response to IL-1 in vitro and that IL-1RI-dependent signaling supports HSC proliferation during alum-induced granulopoiesis. It does not establish that this proliferation drives myeloid differentiation at the expense of self-renewal or erodes HSC repopulating capacity; those outcomes are not reported in the passages retrieved.

  • IL-1 signaling is closely linked to chronic inflammatory diseases and plays a critical role in the activation of inflammatory myelopoiesis.

    “IL-1β is produced in response to a wide range of physiological insults, and IL-1 signaling is closely linked to a wide variety of chronic inflammatory diseases, where it plays a critical role in the activation of inflammatory myelopoiesis (Ueda et al., 2009; Dinarello, 2011; Mirantes et al., 2014; Pietras, 2017).”

    From PU.1 is required to restrain myelopoiesis during chronic inflammatory stress (2023) · cites this paper as Ueda et al., 2009

    The Discussion reports that IL-1RI is indispensable for alum-induced emergency granulopoiesis in mice, supporting a critical role for IL-1 signaling in that inflammatory response. It does not establish the claim’s broader link to a wide variety of chronic inflammatory diseases or show that IL-1 activates myelopoiesis in those diseases. No page number is available in our copy.

    Experimental — accuracy not yet measured
  • Published BM chimera studies show that in vivo HSC proliferation in response to IL-1 can be triggered independently of IL-1 receptor (IL-1R) on HSCs themselves and may rely on IL-1R-induced G-CSF production in the BM niche.

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.
