Genomic characterization of murine monocytes reveals C/EBPb dependence of Ly6C-cells [RNA sequence]

ABSTRACT: We show that monocyte development is accompanied by stepwise RNA expression changes and that Ly6C+ monocytes upon transfer develop into Ly6C- monocytes indicated by a comparable expression profile to host Ly6C- monocytes

Heterogeneity of Ly6G+Ly6C+ myeloid-derived suppressor cell (MDSC) infiltrates during S. aureus biofilm infection

Project description:The two immune cell populations Myeloid-derived suppressor cells (MDSCs), monocytes (MONO) and neutrophils (PMNs) are difficult to differentiate because of shared surface marker expression. Here we utilize the integrin receptor CD11b combined with conventional Ly6G and Ly6C expression to more accurately separate cellular populations via FACS. Then we apply high-throughput RNA Sequencing to Ly6G+Ly6C+CD11bhigh MDSC, Ly6G+Ly6C+CD11blow PMN and Ly6G-Ly6C+ monocyte populations. A total of 6,466 genes were significantly differentially expressed in MDSCs vs. monocytes, whereas only 297 genes were significantly different between MDSCs and PMNs. A number of genes implicated in cell cycle regulation were identified, and in vivo EdU labeling revealed that over 75% of MDSCs proliferated locally at the site of S. aureus biofilm infection.

Expression arrays of inflammatory Ly6C+ monocytes in mice primary or secondary challenged with Listeria monocytogenes

Project description:In this study we investigated the mechanisms involved in memory T-cell mediated protection using mice vaccinated with the intracellular bacterium Listeria monocytogenes. Our working hypothesis was that rapid activation of cells of the innate immune system, in particular inflammatory Ly6C+ monocytes, were essential in effective protection, in a memory T cell-dependent manner. Thus we generated a comprehensive comparison of the genetic program of activated Ly6C+ monocytes during a primary or a secondary infection with Listeria monocytogenes, at 8 hours post challenge infection. Abstract of corresponding publication: Cells of the innate immune system are essential for host defenses against primary microbial pathogen infections, yet their involvement in effective memory responses of vaccinated individuals has been poorly investigated. Here we show that memory T cells instruct innate cells to become potent effector cells in a systemic and a mucosal model of infection. Memory T cells controlled phagocyte, dendritic cell and NK or NK T cell mobilization and induction of a strong program of differentiation, which included their expression of effector cytokines and microbicidal pathways, all of which were delayed in non-vaccinated hosts. Disruption of IFN-gamma-signaling in Ly6C+ monocytes, dendritic cells and macrophages impaired these processes and the control of pathogen growth. These results reveal how memory T cells, through rapid secretion of IFN-gamma, orchestrate extensive modifications of host innate immune responses that are essential for effective protection of vaccinated hosts. Overall design: Inflammatory monocytes were purified (see below for isolation method) from 4 groups of 3 individual mice each (triplicate): (i) uninfected mice, (ii) primary infected, (iii) secondary infected, (iv) secondary infected and T-cell depleted 1 day before. Isolation of cells was done on 3 different days for true biological replicates.

G-CSF mobilizes CD34+ regulatory monocytes that inhibit Graft-versus-Host Disease

Project description:Administration of G-CSF mobilizes a unique population of CD11b+Ly6C+CD34+mature monocytes that can inhibit GVHD in murine models of BMT via an iNOS-dependent mechanism. The transcriptional profiles of flow sorted lineage-CD11b+CD34+ cells from G-CSF treated mice were compared with conventional splenic Ly6C+ and Ly6C- monocytes, progenitor cells and cultured myeloid-derived suppressor cells. Further comparisons were made with lineage-CD11b+CD34+ cells from G-CSF treated mice that had been grown in culture or that were derived from iNOS ko mice. We used microarrays to detail the global programme of gene expression underlying diffrenetiation of each of these cell types Lin-CD11b+CD34+ populations were isolated directly from the spleens of G-CSF-treated C57BL/6 mice or iNOS ko mice. In untreated C57BL/6 mice, Lin-CD11b+CD115+Ly6C+ and Lin-CD11b+CD115+Ly6C- monocytes were isolated from the spleen and Lin-CD117+CD115+CD135-Ly6C+CD11b- common monocyte progenitors were isolated from the bone marrow. Myeloid-derived suppressor cells (Ly6C+CD11b+ cells derived from G-CSF, GM-CSF and IL-13 cultured C57BL/6 bone marrow) were also isolated and compared with the above populations. Lin-CD11b+CD34+ spleen cells derived from G-CSF-treated C57BL/6 mice were cultured for 3 days in Flt3 ligand and SCF and then compared to the original input population.
