Abstract

A role for macrophages in erythropoiesis was suggested several decades ago when erythroblastic islands in the bone marrow, composed of a central macrophage surrounded by developing erythroblasts, were described. However, the in vivo role of macrophages in erythropoiesis under homeostatic conditions or in disease remains unclear. We found that specific depletion of CD169(+) macrophages markedly reduced the number of erythroblasts in the bone marrow but did not result in overt anemia under homeostatic conditions, probably because of concomitant alterations in red blood cell clearance. However, CD169(+) macrophage depletion significantly impaired erythropoietic recovery from hemolytic anemia, acute blood loss and myeloablation. Furthermore, macrophage depletion normalized the erythroid compartment in a JAK2(V617F)-driven mouse model of polycythemia vera, suggesting that erythropoiesis in polycythemia vera remains under the control of macrophages in the bone marrow and splenic microenvironments. These results indicate that CD169(+) macrophages promote late erythroid maturation and that modulation of the macrophage compartment may be a new strategy to treat erythropoietic disorders.

  • The major source of iron for systemic needs, such as red blood cell maturation, are macrophages, which ingest senescent erythrocytes as well as haptoglobin-bound free hemoglobin and heme/Fe complexes released from lysed red blood cells.

    “However, the major source of iron for systemic needs, such as red blood cell (RBC) maturation, are macrophages, which ingest senescent erythrocytes as well as haptoglobin-bound free hemoglobin and heme/Fe complexes released from lysed RBCs (Burger et al., 2012; Chow et al., 2013).”

    From The Role of Iron Regulation in Immunometabolism and Immune-Related Disease (2019) · cites this paper as Chow et al., 2013

  • A moderate decrease of iron supply to erythroblasts as deduced from reduced Hb content in reticulocytes was observed after EIM depletion.

    “Concretely, a moderate decrease of iron supply to erythroblasts as deduced from the reduced Hb content in reticulocytes was observed [38].”
  • Depletion of EIM (and other CD169+ macrophages) had only little impact on the restoration of erythropoiesis after bone marrow transplantation.

    “Data in support of this concept has been generated using the CD169-DTR model: The depletion of EIM (and other CD169+ macrophages) had only little impact on the restoration of erythropoiesis after BM transplantation.”

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.
