Monocytic cell differentiation from band-stage neutrophils under inflammatory conditions

ABSTRACT: During inflammation, neutrophils are rapidly mobilized from the bone marrow storage pool into peripheral blood to subsequently enter lesional sites where most of them rapidly undergo apoptosis. Monocytes constitute a second wave of inflammatory immigrates giving rise to long-lived macrophages and dendritic cell subsets. According to descriptive immunophenotypic and cell culture studies, neutrophils may directly M-bM-^@M-^\transdifferentiateM-bM-^@M-^] into monocytes/macrophages. We here provide mechanistic data in human supporting the existence of this cellular pathway. Global transcriptional profiling of neutrophil-dervived monocytic cells revealed close resemblance of gene expression with monocytes and a clear separation of these cells from neutrophils. G-CSF mobilized neutrophils from peripheral blood were isolated and in vitro stimulated with GM-CSF, TNFa, and Il-1b for 5 days to generate monocytic cells. RNA were isolated from these cells and freshly isolated blood neutrophils and monocytes.

Monocytes constitute a second wave of inflammatory immigrates giving rise to long-lived macrophages and dendritic cell subsets. According to descriptive immunophenotypic and cell culture studies, neutrophils may directly “transdifferentiate” into monocytes/macrophages. We here provide mechanistic data in human supporting the existence of this cellular pathway. Global transcriptional profiling of neutrophil-dervived monocytic cells revealed close resemblance of gene expression with monocytes and a clear separation of these cells from neutrophils.

AMD3100 and G-CSF Mobilize Different CD34+ Cell Populations Based on Gene and miRNA Expression

Project description:Plerixafor (AMD3100) and G-CSF mobilize peripheral blood stem cells (PBSCs) by different mechanisms. A rhesus macaque model was used to compare plerixafor and G-CSF-mobilized CD34+ cells. Three PBSC concentrates were collected from 3 macaques treated with G-CSF, plerixafor, or plerixafor plus G-CSF. CD34+ cells were isolated by immunoselection and were analyzed by global gene and micro RNA (miR) expression microarrays. Unsupervised hierarchical clustering of the gene expression data separated the CD34+ cells into three groups based on mobilization regimen. Plerixafor-mobilized cells were enriched for B cells, T cells and mast cells genes and G-CSF-mobilized cells were enriched for neutrophils, and mononuclear phagocytes (MPs) genes. Genes up-regulated in plerixafor plus G-CSF-mobilized CD34+ cells included many that were not up-regulated by either agent alone. Two hematopoietic progenitor cell miR, miR-10 and miR-126, and a dendritic cell miR, miR-155, were up-regulated in G-CSF-mobilized CD34+ cells. A pre-B cell acute lymphocytic leukemia miR, miR-143-3p, and a T cell miR, miR-143-5p, were up-regulated in plerixafor plus G-CSF-mobilized cells. The composition of CD34+ cells is dependent on the mobilization protocol. Plerixafor-mobilized CD34+ cells include more B, T, and mast cell precursors while G-CSF-mobilized cells have more neutrophil and MP precursors. Three rhesus macaques were given all three mobilization protocols and PBSCs were collected from each of these three animals. Two monkeys were given plerixafor first, one was given G-CSF first and all three were given plerixafor plus G-CSF last. This resulted in 6 samples (CD34+ and CD34- cells from each of the 3 mobilizations) from each of the 3 individual animals (biological replicates).

Genomic modulators of gene expression in human neutrophils

Project description:Neutrophils form the most abundant leukocyte subset and are central to many disease processes. Technical challenges in transcriptomic profiling have prohibited genetical genomic approaches to date. Here, we map expression quantitative trait loci (eQTL) in peripheral blood CD16+ neutrophils from 101 healthy European adults. This dataset includes expression data from neutrophils. The genotypes and expression data from monocytes can be found in E-MTAB-2232 - Genetics of gene expression across innate immune stimulation in primary monocytes.

Peripheral blood stem cell gene profiling

Project description:Mobilized-peripheral blood hematopoietic stem cells (HSCs) have been used for transplantation, immunotherapy, and cardiovascular regenerative medicine. Agents used for HPC mobilization include G-CSF and the CXCR4 inhibitor AMD3100. The HSCs cells mobilized by each agent may contain different subtypes and have different functions. To characterize mobilized HSCs used for clinical applications, microRNA (miRNA) profiling and gene expression profiling were used to compare AMD3100-mobilized CD133+ cells from 4 subjects, AMD3100 plus G-CSF-mobilized CD133+ cells from 4 subjects and G-CSF-mobilized CD34+ cells from 5 subjects. The HSCs were compared to peripheral blood leukocytes (PBLs) from 7 subjects. Keywords: cell type comparison design gene expression profiling were used to compare AMD3100-mobilized CD133+ cells from 4 subjects, AMD3100 plus G-CSF-mobilized CD133+ cells from 4 subjects and G-CSF-mobilized CD34+ cells from 5 subjects.

Bulk RNA-Seq of human neutrophils and monocytes isolated from healthy controls, G-CSF-treated donors, HSCT, PDAC and IPMN patients

Project description:We aimed to characterize transcriptome plasticity of human myeloid cells in response to stress induced myelopoiesis. We performed bulk RNA sequencing (RNA-Seq) analyses of normal density neutrophils (NDNs), low density neutrophils (LDNs), and monocytes isolated from the peripheral blood (PB) of healthy controls (n=19), of G-CSF-treated donors (n=17) as well as of patients receiving hematopoietic stem cell transplantation (HSC-T; n=8), patients with locally advanced or metastatic pancreatic ductal adenocarcinoma (PDAC; n=15) or intraductal papillary mucinous neoplasms (IPMN; n=14). We also analyzed neutrophil differentiation intermediates from bone marrow samples of controls (n=3) or HSC-T patients (n=7). We generated a total of 210 RNA-Seq samples from 73 individuals.

Changes in gene expression of granulocytes during in vivo G-CSF/dexamethasone mobilization.

Project description:Treatment of healthy donors with G-CSF and dexamethasone, results in sufficient number of circulating granulocytes to prepare granulocyte concentrates for clinical purposes. Granulocytes obtained this way demonstrate relatively normal functional behavior combined with a prolonged life span. To study the influence of mobilizing agents on granulocytes, we used oligonucleotide microarrays to identify genes that are differentially expressed in mobilized granulocytes as compared to control ones. Keywords: mobilized granulocytes, G-CSF/dexamethasone treated granulocytes Granulocytes were isolated from three individuals before (control situation) and 18 hours after treatment with G-CSF&dexamethasone; part of the control cells was cultured overnight in HBSS medium with or without addition of G-CSF and dexamethasone. Total RNA from each experimental condition was compared to pooled RNA of control granulocytes.

Comparison of monocytes from G-CSF mobilized and normal peripheral blood

Project description:A prospective randomized trial has shown that there is a survival advantage for allogeneic transplant patients receiving Granulocyte Colony Stimulating Factor (G-CSF) stimulated peripheral blood mononuclear cells (GPBMC) versus bone marrow (BM) as a source of stem cells. The biological basis for this advantage is not clear, and may be attributable to qualitative as well as quantitative differences in the CD34 cells, T-cells and/or the monocytes transplanted. To begin to address this issue, gene expression patterns in monocytes isolated from G-CSF mobilized peripheral blood were compared those from normal, non-mobilized peripheral blood to identify functional pathways that may distinguish these two populations. Keywords: Cell type comparison

Identification of bone morphogenetic protein (BMP)-7 as a key instructive factor for human epidermal Langerhans cell differentiation and proliferation

Project description:Langerhans dendritic cells represent abundantly occuring and evolutionary highly conserved DCs specifically located in the stratified epithelial tissues. LCs are unique among DC family members in that they express epithelial-type adhesion molecules, allowing them to form a tight three-dimensional network in basal and suprabasal epidermal keratinocyte layers and developmentally dependent on the cytokine TGF-M-NM-21. In the present study, we identified BMP-7 as another key factor inducing LC differnetiation. Here we have performed comparative analysis of highly purified CD207+/CD1a+ in vitro generated Langerhans cells in the presence of BMP-7 and TGF-M-NM-21. We have identified that both BMP-7-LCs and TGF-M-NM-21-LCs are closely related to each other. CD34+ hematopoietic stem cells were isolated from freshly obtained cord blood and cultured in the presence of GM-CSF, SCF, Flt3L, TNFa and either TGF-M-NM-21 or BMP-7 for 7 days to get immature LCs. RNA was isolated from these in vitro genetared LCs.
