Abstract

Psychosocial stress accelerates myelopoietic production of monocytes and neutrophils that contributes to a variety of health complications ranging from atherosclerosis to anxiety. Here, we show that social stress in mice mobilizes hematopoietic stem progenitor cells (HSPCs) from the bone marrow that enter circulation, engraft into the spleen, and establish a persistent extramedullary hematopoietic depot. These splenic progenitors actively proliferate and differentiate into multiple cell types, including monocytes, neutrophils, and erythrocytes. Splenic erythropoiesis partially abrogates stress-induced anemia. Repeated injection with isoprenaline induces progenitor mobilization to the spleen, identifying a key role for β-adrenergic signaling. Moreover, protracted splenic production of CD11b + cells persists for at least 24 days after the cessation of social stress. Thus, chronic stress establishes a persistent extramedullary hematopoietic depot that can modify a wide range of chronic disease processes and alter homeostasis of the bi-directional regulatory axis between the nervous and immune systems.

  • Mice exposed to CVS or CSDS show expansion of myeloid progenitor cells and reduced lymphoid progenitors.

    “Specifically, mice exposed to either CVS or CSDS exhibit an expansion of myeloid progenitor cells, along with a downregulation of lymphoid progenitors33,59.”

    From Central regulation of stress-evoked peripheral immune responses (2023) · cites this paper as [59]

    The Results sections report increased myeloid progenitor colony-forming units after repeated social defeat stress, alongside reduced lymphocyte proportions in bone marrow and blood. They do not establish a reduction in lymphoid progenitors. The Introduction mentions increased myeloid cell production under chronic variable stress, but does not report myeloid progenitor expansion or reduced lymphoid progenitors under that condition. Page numbers were not available in our copy. (LLM, conf=0.88)

  • Chronic social stress in mice causes splenomegaly attributed to granulocyte accumulation and extramedullary myelopoiesis, which raises circulating monocyte levels.

    “Chronic social stress in mice leads to splenomegaly, attributed to granulocyte accumulation and ectopic (or ‘extramedullary’) myelopoiesis, which consequently elevates circulating monocyte levels59,77.”

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.
