Project description:The peritoneal cavity is home to various immune cells. Previous studies have investigated the heterogenous nature of peritoneal myeloid mononuclear cells. However, up to this date, there are no clear criteria to distinguish peritoneal macrophages and dendritic cells (DCs). In the present study, we delineate the subsets of myeloid mononuclear cells in the mouse peritoneal cavity. Considering phenotypical, functional, and ontogenic features, peritoneal myeloid mononuclear cells are divided into 5 subsets: large peritoneal macrophages (LPMs), small peritoneal macrophages (SPMs), DCs, and 2 MHCII+CD11c+CD115+ subpopulations (i.e., MHCII+CD11c+CD115+CD14-CD206- and MHCII+CD11c+CD115+CD14+CD206+). Among them, 2 subsets of competent antigen presenting cells are demonstrated with distinct functional characteristics, one being DCs and the other being MHCII+CD11c+CD115+CD14-CD206- cells. DCs are able to promote fully activated T cells and superior in expanding cytokine producing inflammatory T cells, whereas MHCII+CD11c+CD115+CD14-CD206- cells generate partially activated T cells and possess a greater ability to induce regulatory T cells under TGF-β and retinoic acid conditions. While the development of DCs and MHCII+CD11c+CD115+CD14-CD206- cells are responsive to the treatment of FLT3L and GM-CSF, the numbers of LPMs, SPMs, and MHCII+CD11c+CD115+CD14+CD206+ cells are only influenced by the injection of GM-CSF. In addition, the analysis of transcriptomes reveals that the gene expression profile of MHCII+CD11c+CD115+CD14+CD206+ cells share high similarity with that of SPMs. Collectively, our study identifies 2 distinct subpopulations of MHCII+CD11c+CD115+ cells, (i) MHCII+CD11c+CD115+CD14-CD206- cells closely related to DCs and (ii) MHCII+CD11c+CD115+CD14+CD206+ cells to SPMs.

Among them, 2 subsets of competent Ag presenting cells are demonstrated with distinct functional characteristics, one being DCs and the other being MHCII+CD11c+CD115+CD14-CD206- cells. DCs are able to promote fully activated T cells and superior in expanding cytokine producing inflammatory T cells, whereas MHCII+CD11c+CD115+CD14-CD206- cells generate partially activated T cells and possess a greater ability to induce Treg under TGF-β and retinoic acid conditions. While the development of DCs and MHCII+CD11c+CD115+CD14-CD206- cells are responsive to the treatment of FLT3 ligand and GM-CSF, the number of LPMs, SPMs, and MHCII+CD11c+CD115+CD14+CD206+ cells are only influenced by the injection of GM-CSF. In addition, the analysis of gene expression profiles among MHCII+ peritoneal myeloid mononuclear cells reveals that MHCII+CD11c+CD115+CD14+CD206+ cells share high similarity with SPMs, whereas MHCII+CD11c+CD115+CD14-CD206- cells are related to peritoneal DC2s. Collectively, our study identifies 2 distinct subpopulations of MHCII+CD11c+CD115+ cells, 1) MHCII+CD11c+CD115+CD14-CD206- cells closely related to peritoneal DC2s and 2) MHCII+CD11c+CD115+CD14+CD206+ cells to SPMs.

Project description:Purpose: The goals of this study are to compare CD115- monocytes to CD115+ monocytes from naïve and tumor-bearing mice (EL4) with high-throughput data analysis. Methods: CD115- monocytes and CD115+ monocytes were sorted by flow cytomentry separatly. Total RNA was extracted from cells using the RNeasy Mini Kit (QIAGEN, Hilden, Germany) and residual DNA was removed with a DNA-free Kit (Thermo Fisher Scientific, Waltham, MA, USA) according to the manufacturer’s instructions. Samples were loaded onto a 1% agarose gel before electrophoresis. DNA-free conditions were confirmed by SYBR Gold staining (Invitrogen). The quantity and the quality of RNA was evaluated by Nanodrop 2000 spectrophotometer (Thermo Fisher Scientific) and bioanalyzer (Agilent 2100; Agilent Technologies, Santa Clara, CA, USA). RNA-Seq libraries were prepared with 1 μg of total RNA from two biological replicates of each group using TruSeq Stranded mRNA LT Sample Prep Kit and analyzed by Illumina Sequencer (both from Illumina, San Diego, CA, USA). Results: We found 1,723 differetially expressed genes (DEGs) between CD115- monocytes and CD115+ monocytes (cutoff value was set at 2-fold). DEGs of interest are invoved in granulocyte, transcription factors, mononuclear phagocytes, and angiogenesis. Conclusions: Our study represents the first detailed DEGs analysis of CD115- monocytes and CD115+ monocytes from naïve and tumor-bearing mice. Our results show that CD115- monocytes may have a closer relationship with neutrophils or PMN-MDSCs than the CD115+ monocytes. Also, our overall transcriptomic analysis further suggests that CD115- M-MDSCs and monocytes are separate subsets of monocytic cells.

Project description:CD11c+ Myeloid Dendritic Cells (mDCs) were isolated from the peripheral blood mononuclear cells (PBMCs) of HIV uninfected and HIV infected subjects. The expression of CD11c+ mDCs was accessed to determine how HIV infection may play a role on the expression profiles of these cells. mDCs are known to play a role in antigen presentation, and thus are pivotal in immune sensing and priming of the adaptive immune response. We wanted to see if the change in immune system function during chronic HIV infection may be due to defects in this cell subtype. We used microarray analysis to detail the global program of gene expression underlying changes in mDC function during HIV infection. PBMCs were isolated from HIV uninfected and HIV infected blood samples. CD11c+ cells were sorted from the whole PBMC population by magnetic bead sorting (anti-CD11c antibody bound to a magnetic bead inclubated with whole PBMCs). RNA was isolated from this sorted population to get the gene expression of this subtype of cells.

Project description:The immune system of SPF mice is dominated by naïve phenotype immune cells, especially within the T cell compartment, and resembles that of neonatal humans (Beura et al., 2016; Reese et al., 2016). Sequential infection of SPF-housed laboratory mice with common experimental pathogens, such as MHV, MCMV, Listeria monocytogenes, LCMV, and influenza A virus (Berton et al., 2022; Reese et al., 2016), or cohousing (CoH) SPF mice with pet store mice carrying multiple pathogenic and commensal bacteria, viruses, and/or fungi (Beura et al., 2016) induces immune system alterations and maturations that more closely resemble the adult human immune system. Such microbial exposure drastically alters the composition and function of the immune system of laboratory mice, which can significantly influence the overall outcome (and survival) to subsequent infection. Here we report CD11b+ CD115+ monocytes sorted from female specific pathogen-free (SPF) C57BL/6N (B6) mice co-housed with petstore mice for 60 days are transcriptionally different than SPF CD11b+ CD115+ monocytes
