Microarray expression data from bone marrow monocytes and myeloid progenitors

Project description:Ly6Clo monocytes are a myeloid subset that specializes in the surveillance of vascular endothelium. Ly6Clo monocytes have been shown to derive from Ly6Chi monocytes. Notch2 signaling has been implicated as a trigger for Ly6Clo monocyte development, but the basis for this effect is unclear. Here, we examined the impact of Notch2 signaling of myeloid progenitors on the development of Ly6Clo monocytes in vitro. Notch2 signaling induced by delta-like ligand 1 (DLL1) efficiently induced the transition of Ly6Chi TremL4– monocytes into Ly6Clo TremL4+ monocytes. We further discovered two additional transcriptional requirements for development of Ly6Clo monocytes. Deletion of Bcl6 from myeloid progenitors abrogated development of Ly6Clo monocyte development. IRF2 was also required for Ly6Clo monocyte development in a cell-intrinsic manner. DLL1-induced in vitro transition into Ly6Clo TremL4+ monocytes required IRF2 but unexpectedly could occur in the absence of Nur77 or Bcl6. These results imply a transcriptional hierarchy for these factors in controlling Ly6Clo monocyte development. This experiment compare RNA expression profiles between nonclassical monocytes and various cell types involved in their development.

Microarray analysis of WT bone marrow myeloid progenitors, BM cultured with GM-CSF and M-CSF, and monocytes treated with GM-CSF

Project description:Analysis of genes induced in DC precursors and in BM cells and monocytes treated with GM-CSF For progenitor arrays, bone marrow progenitors (CMP, GMP, CDP, and pre-cDC) were harvested from WT C57Bl/6 mice. For culture arrays, BM was cultured in the presence of GM-CSF or M-CSF and adherent and non-adherent cells sorted. For monocyte cultures, sorted BM monocytes were treated with GM-CSF for 0, 24 or 48 hours.

scRNAseq reveals heterogeneity among mouse bone marrow Ly6Chi monocytes produced by GMPs and MDPs

Project description:Granulocyte-monocyte progenitors (GMPs) and monocyte-dendritic cell progenitors (MDPs) produce monocytes during homeostasis and in response to increased demand during infection. Both progenitor populations are thought to derive from common myeloid progenitors (CMPs), and a hierarchical relationship (CMP-GMP-MDP-monocyte) is presumed to underlie monocyte differentiation. Here, however, we demonstrate that mouse MDPs arose from CMPs independently of GMPs, and that GMPs and MDPs produced monocytes via similar, but distinct, monocyte-committed progenitors. GMPs and MDPs yielded classical (Ly6Chi) monocytes with gene expression signatures that were defined by their origins and impacted their function. GMPs produced a subset of “neutrophil-like” monocytes, whereas MDPs gave rise to a subset of monocytes that yielded monocyte-derived dendritic cells. GMPs and MDPs were also independently mobilized to produce specific combinations of myeloid cell types following the injection of microbial components. Thus, the balance of GMP and MDP differentiation shapes the myeloid cell repertoire during homeostasis and following infection.

COMMD10-deficiency promotes 'neutrophil like' differentiation fate of bone marrow Ly6Chi monocytes

Project description:Monocytes are circulating myeloid immune precursor cells that are generated in the bone marrow (BM). Upon their release into the circulation, monocytes are recruited to inflammatory sites, where they differentiate into monocyte-derived effector cells. In absence of overt inflammation, monocytes also extravasate into selected tissues, where they complement tissue-resident macrophage compartments. Recent studies have uncovered binary developmental trajectories of monocytes in the BM with Neutrophil-like (NeuMo) and dendritic cell (DC)-like (DCMo) monocytes differentiating downstream of granulocyte-macrophage progenitors (GMP) and macrophage-dendritic cell progenitors (MDP), respectively (Weinreb et al., 2020; Yanez et al., 2017). Yet, the molecular cues that dictate BM monocyte differentiation remain incompletely understood. The COMMD (copper metabolism MURR1 domain) family includes 10 evolutionarily conserved proteins. Functions of COMMD proteins are still being defined, but they seem to play non-redundant roles in regulating transcription and protein trafficking. Utilizing conditional COMMD10 knockout mice we uncovered a role for COMMD10 in limiting inflammasome activation in Ly6Chi monocytes during experimental sepsis and colitis (Mouhadeb et al., 2018), and in supporting phagolysosomal biogenesis and maturation in KCs and BM-derived macrophages infected with Staphylococcus aureus (Ben Shlomo et al., 2019). Hence, these studies mark COMMD10 as a candidate mediator of monocyte and macrophage fate and immune responses. Here we studied the effect of COMMD10-deficiency on Ly6Chi monocyte differentiation. We show that COMMD10-deficiency in steady state Ly6Chi monocytes promotes a differentiation bias towards NeuMo fate.
