STAT3 controls myeloid progenitor growth during emergency granulopoiesis

Open access

Abstract

Granulocyte colony-stimulating factor (G-CSF) mediates “emergency” granulopoiesis during infection, a process that is mimicked by clinical G-CSF use, yet we understand little about the intracellular signaling cascades that control demand-driven neutrophil production. Using a murine model with conditional deletion of signal transducer and activator of transcription 3 (STAT3) in bone marrow, we investigated the cellular and molecular mechanisms of STAT3 function in the emergency granulopoiesis response to G-CSF administration or infection with Listeria monocytogenes, a pathogen that is restrained by G-CSF signaling in vivo. Our results show that STAT3 deficiency renders hematopoietic progenitor cells and myeloid precursors refractory to the growth-promoting functions of G-CSF or L monocytogenes infection. STAT3 is necessary for accelerating granulocyte cell-cycle progression and maturation in response to G-CSF. STAT3 directly controls G-CSF–dependent expression of CCAAT-enhancer-binding protein β (C/EBPβ), a crucial factor in the emergency granulopoiesis response. Moreover, STAT3 and C/EBPβ coregulate c-Myc through interactions with the c-myc promoter that control the duration of C/EBPα occupancy during demand-driven granulopoiesis. These results place STAT3 as an essential mediator of emergency granulopoiesis by its regulation of transcription factors that direct G-CSF–responsive myeloid progenitor expansion.

    The Discussion (page not provided) mentions patients with hyper-IgE syndrome but says their emergency granulopoiesis and neutrophil function have not been investigated extensively. The reported blood-cell and progenitor findings concern mice, not AD-HIES patients. Searches for AD-HIES blood-cell counts and hematopoiesis found no passage establishing the claimed absence of quantitative defects in patients. (LLM, conf=0.78)

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.
