Project description:Myeloid-derived suppressor cells (MDSCs) have emerged as major regulators of immune responses in cancer and other pathological conditions. Multiple factors including cytokines, transcription factors and multiple signaling pathways are involved in MDSC differentiation. Cytokines such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin(IL-6) etc could in vitro mediate development of MDSCs.IL-6 with GM-CSF mediated MDSC not only had stronger suppressive function but also the dynamics of their suppressive function was different from GM-CSF alone mediated MDSCs.To found a new regulatory factor (s) in tumor and inflammatory environments, we compared GM-CSF and IL-6 mediated MDSCs with GM-CSF alone mediated MDSCs using lncRNA microarray, miRNA microarrays and protein-coding mRNA microarrays.

Project description:Inflammatory responses must be tightly coordinated with the activation of emergency myelopoiesis to produce potent myeloid cells that fight infection without causing self-damage. Here we show that GM-CSF programs myeloid committed progenitors to produce trained macrophages (increased cytokine response), but programs the upstream non-committed LKS+ progenitors to produce tolerized macrophages (decreased cytokine response). In myeloid progenitors, GM-CSF strongly activates STAT5, ERK and Akt-mTOR signaling pathways which are essential to establish a training program, whereas in LKS+ progenitors GM-CSF induces NF-κB translocation to the nucleus to establish a tolerization program. These differences arise from higher GM-CSF receptor expression in myeloid progenitors compared to LKS+ cells. We demonstrate that β-catenin regulation of NF-κB nuclear translocation is central in this process. Glycogen synthase kinase 3 (GSK3) inactivation by strong ERK and PI3K-Akt signaling increases cytoplasmic β-catenin levels to block NF-κB nuclear translocation in myeloid progenitors. In contrast, when ERK and PI3K-Akt signaling is weak, active GSK3 decreases β-catenin to allow NF-κB nuclear translocation in LKS+ progenitors. Finally, GM-CSF-induced LKS+ tolerization can be reversed and takes place in several murine models of trained immunity and in human CD34+ CD38– progenitors. Our study reveals that in addition to activating myelopoiesis, GM-CSF also programs early and immediate myeloid progenitors to produce opposing immune memory phenotypes. We propose that the inflammatory response from immediate myeloid progenitors may be balanced by the tolerized phenotype of early progenitors, thus providing a mechanism for appropriate resolution of inflammation and protection against prolonged cytokine storm.

Project description:MDSC (myeloid-derived suppressor cells) can be differentiated in vitro using IL-6 and GM-CSF. To identify the specific role of IL-6 in this process, we used microarray to compare MDSC differentiated with IL-6 and GM-CSF to MDSC differentiated with GM-CSF alone. We have found genes and pathways that are up- or downregulated when IL-6 is present.

Project description:In recent years, the M-CSF and GM-CSF cytokines have been identified as opposing regulators of the inflammatory program. However, the two cytokines are simultaneously present in the inflammatory milieu, and it is not clear how cells integrate these signals. In order to understand the regulatory networks associated with the GM/M-CSF signaling axis we analyzed DNA methylation in human monocytes. Our results indicate that GM-CSF induces activation of the inflammatory program and extensive DNA methylation changes, while M-CSF-polarized cells are in a less differentiated state. This inflammatory program is mediated via JAK2 associated with the GM-CSF receptor and the downstream ERK signaling. However, PI3K signaling is associated with a negative regulatory loop of the inflammatory program and M-CSF autocrine signaling in GM-CSF-polarized monocytes. Our findings describe the regulatory networks associated with the GM/M-CSF signaling axis and how they contribute to the establishment of the inflammatory program associated with monocyte activation.

Project description:GM-CSF is involved in immune complex (IC)-mediated arthritis. However, little is known about what is the cellular source of GM-CSF and how it is regulated during IC-mediated inflammation. Using novel GM-CSF reporter mice, we show that NK cells produce GM-CSF during an IC-mediated model of inflammatory arthritis. NK cells promoted STIA in a GM-CSF-dependent manner, as deletion of NK cells and selective removal of GM-CSF production by NK cells abrogated disease. Furthermore, we show that myeloid cell activation by GM-CSF is restrained by induction of JAK/STAT checkpoint inhibitor cytokine-inducible SH2-containing protein, CIS. Myeloid cells from CIS-deficient mice had exaggerated responses to GM-CSF, and these mice develop exacerbated STIA. Our data suggest that tissue NK cells may amplify joint inflammation in arthritis via GM-CSF production and thus represent a novel target in IC-mediated pathology. Endogenous CIS provides a key brake on signaling through the GM-CSF receptor and strategies that boost its function may provide an alternative anti-inflammatory approach.

Project description:Purpose: We report the application of single-cell RNA sequencing for profiling the genexpression of different monocyte types in order to characterize monocytes that differentiate into macrophages under danger signal in comparison to conventional GM-CSF and M-CSF macrophages Methods: Monocytes freshly isolated from PBMCs were differentiated into GM-CSF, M-CSF, and danger-signal induced macrophages. Two million cells of each macrophage population were tagged accordingly with TotalSeq™‑B Hashtags. Single cell RNA sequencing was performed on all macrophage populations in order to characterize cells from each population. ScRNAseq analysis was performed with the R package Seurat on 16470 barcodes after filtering. Results: Cluster analysis reveals distinct separation of all three macrophage populations. Conclusion: The clear difference in overall gene expression profile suggests that macrophages exposed to danger signal differentiate into a novel macrophage type in contrast to conventional GM-CSF and M-CSF monocytes.

Project description:Bone marrow cells were isolated, primed with M-CSF (M-BMDM) or GM-CSF (GM-BMDM) and cultured for 7 days. The proteomic difference between GM-BMDM and M-BMDM were analyzed to describe the phenotye and function of two types of macrophages.

Project description:Granulocyte-Macrophage colony stimulating factor (GM-CSF) devlops heterogenous myeloid cell populations from bone marrow progenitor cells. In vitro generated bone marrow derived cells are excellent sources for obtaining dendritic cells or macrophages, but it is still not clear about the exact mixed population characteristics of GM-CSF grown cells. We revealed here that GM-CSF grown bone marrow cell derived attaching cells were composed of dendritic cells (GM-BMDC) as well as macrophages (GM-BMM). We compared the transcriptome profiles of these cell populations as well as M-CSF grown bone marrow derived macrophages (M-BMM). We used microarrays to detail the global profile of gene expressions between three populations of CSF-grown bone marrow derived cells: GM-CSF derived dendritic cells (GM-BMDC), GM-CSF derived macrophages (GM-BMM) and M-CSF derived macrophages (M-BMM).

Project description:Pulmonary conventional dendritic cells (cDCs) are functionally and phenotypically heterogeneous antigen-presenting cells essential for orchestrating adaptive immune responses in the lung. Here, we define a critical role for granulocyte-macrophage colony-stimulating factor (GM-CSF) in generating a CD301b+ subset of terminally differentiated cDC2s. GM-CSF signaling is intrinsically required for their development, independent of GM-CSF-dependent alveolar macrophages. Absence of GM-CSF results in a defect similar to that seen in CD103+XCR1+ cDC1s. Unbiased single-cell transcriptomic profiling of CD11c+ cells identified both immature and differentiated cDC populations. GM-CSF deficiency disrupted anti-apoptotic Bcl2a1 upregulation and impaired progression to the CD301b+ transcriptional state. Despite their positioning in lymphoid cell-rich adventitial cuff areas, hematopoietic GM-CSF was dispensable. Instead, genetic GM-CSF gain- and loss-of-function studies showed that alveolar epithelial type 2 cell-derived GM-CSF is required for CD301b+ cDC2 formation and pulmonary type 2 immune responses, highlighting the central role of GM-CSF signaling in shaping the pulmonary myeloid landscape.
