Abstract

Hematopoietic stem cells (HSCs) maintain life-long production of immune cells and can directly respond to infection, but sustained effects on the immune response remain unclear. We show that acute immune stimulation with lipopolysaccharide (LPS) induced only transient changes in HSC abundance, composition, progeny, and gene expression, but persistent alterations in accessibility of specific myeloid lineage enhancers occurred, which increased responsiveness of associated immune genes to secondary stimulation. Functionally, this was associated with increased myelopoiesis of pre-exposed HSC and improved innate immunity against the gram-negative bacterium P. aeruginosa. The accessible myeloid enhancers were enriched for C/EBPβ (targets, and C/EBPβ deletion erased the long-term inscription of LPS-induced epigenetic marks and gene expression. Thus, short-term immune signaling can induce C/EBPβ-dependent chromatin accessibility, resulting in HSC-trained immunity, during secondary infection. This establishes a mechanism for how infection history can be epigenetically inscribed in HSC as an integral memory function of innate immunity.

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.
