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:Acute myeloid leukemia (AML) is a highly heterogeneous disease. In our study, we found that overexpressing IL-34 in AML cells accelerates the AML progression and shorten the mice survival, which is medicated by LSC level. We used one of the LSC markers, c-Kit, to divide AML cells. The goals of this study aim to reveal the mechanism mediated by IL-34 overexpression, we performed the RNAseq profiling of MA9-c-kit-, MA9-c-kit+ and MA9-IL-34 AML cells.

Project description:Interleukin-34 (IL-34) is an alternative ligand to colony-stimulating factor-1 (CSF-1) for the CSF-1 receptor that acts as a key regulator of monocyte/macrophage lineage. In this study, we show that cancer cells-derived IL-34 mediates resistance to immune checkpoint blockade regardless of CSF-1 existence. In a therapeutic study of a programmed death-1 and cytotoxic T-lymphocyte-associated antigen-4 blocking monoclonal antibody, the expression of IL-34 in tumors was accompanied with limited benefits compared to IL-34 non-expressing tumors in various murine cancer models. Consistent with its immunosuppressive characteristics, the expression of IL-34 in tumors correlates with decreased frequencies of cellular (such as CD8+ and CD4+ T cells) and molecular (including various cytokines and chemokines) effectors at the tumor microenvironment. In addition, IL-34 blockade expands the M1-macrophage population. Then, a neutralizing antibody against IL-34 helped to reverse these effects and improved the therapeutic effects of the immune checkpoint blockade in combinatorial therapeutic models, including a patient-derived xenograft model of primary lung adenocarcinoma. Collectively, we revealed that tumor-derived IL-34 inhibits the efficacy of immune checkpoint blockade and proposed the utility of IL-34 blockade as a new strategy for cancer therapy.

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.

Project description:We found a unique subset of effector memory (EM) CD8+ T cells that expressed high levels of IL-6 receptor in human peripheral blood. These cells which also expressed high levels of IL-7Ra (referred to as IL-6R high IL-7Rahigh cells) had the a distinct gene expression profile and cellular characteristics compared to other EM CD8+ T cells. IL-6R high IL-7Ra high cells were early differentiated EM CD8+ T cells with decreased expression of T-bet, KLRG1, perforin and granzyme B. These cells had increased cell proliferation likely secondary to enhanced IL-2 production and high affinity IL-2R expression. IL-6R high IL-7Ra high EM CD8+ T cells exclusively produced high levels of IL-2, IL-5, IL-9 and IL-13 although IFN-r was produced by this cell subset and other EM CD8+ T cells. Of interest, IL-6R high IL-7Ra high EM CD8+ T cells expanded in the peripheral blood of patients with chronic obstructive pulmonary disease (COPD) and asthma where CD8+ T cells, IL-13 and IFN-r are suggested to be involved in the pathogenesis. Being the early-differentiated EM CD8+ T cells with a potent capacity to proliferate, survive and generate multiple cytokines, IL-6R high IL-7Ra high EM CD8+ T cells may serve as a primary reservoir for effector CD8+ T cells which potently expand and produce cytokines upon immune stimulation. Duplicate experiments were performed for each condition. In each condition, we independently prepared total RNA using the RNeasy mini kit (Qiagen) and assessed RNA integrity using Bioanalyzer 2100 (Agilent)- RINs were close to 10 for all samples. RNA was then amplified and hybridized to the Illumina HumanHT-12 v4.0 BeadChip, according to Illumina standard protocols.
