Expression data from sorted monoyctes/macrophages

ABSTRACT: Tissue injury, such as incisional wound, results in an inflammatory response as well as acute to chronic mechanical and thermal pain. It is now understood that there is a strong contribution of these immune cells to the pain phenotype. We used microarray analysis of sorted CD11b+Ly6G- myeloid cells extracted from the mouse hindpaw 24h after incisional wound to identify distinct classes of upregulated genes. CD11b+Ly6G- myeloid cells were sorted by expression of Ly6C (high, medium, and low) and used for microarray analysis. All sorted cells were collected on the same day to reduce variability.

Quantitative Temporal in vivo Proteomics (QTiPs) deciphers the transition of inflammatory CD11b+,Ly6G-,Ly6Chigh myeloid cells into M2-like macrophages

Project description:Phenotypic transition of myeloid cells into distinct lineages in vivo is important in pathogen response. To monitor immune cell phenotype transitions in vivo, we developed a quantitative temporal in vivo proteomics (QTiPs) platform, performing multiplexed (10-plex) tandem-mass-tag (TMT)-based mass spectrometry on sorted cells collected from their in situ microenvironment during infection. We temporally characterized a poorly understood, virus-driven CD11b+,Ly6G-,Ly6Chigh-low myeloid cell population throughout an acute phase of infection in both the site of infection and bone marrow. QTiPs, in combination with phenotypic, functional and metabolic analyses, elucidated a pivotal role for inflammatory CD11b+,Ly6G-,Ly6Chigh-low cells in anti-viral immune response and viral clearance. Most importantly, the highly time-resolved QTiPs dataset showed the transition of CD11b+,Ly6G-,Ly6Chigh-low cells into M2-like macrophages which displayed increased antigen presentation capacities and bioenergetic demands late in infection. Our QTiPs approach precisely captures myeloid cell-macrophage transition in this population, and it is a novel platform for measuring temporospatial proteome transitions in vivo.

Effect of rapamycin on murine subcutaneous MC38 tumor cell populations

Project description:To determine differential metabolic gene expression in distinct cell populations from subcutaneous MC38 tumors at baseline and in response to rapamycin, tumors from mice treated with vehicle or rapamycin were harvested, reconstituted to single cell suspensions, and flow sorted into cancer cell (CD45-), tumor-associated macrophage (TAM, CD45+ CD11b+ Ly6G- Ly6C lo F4/80 hi), monocytic myeloid-derived suppressor cell (M-MDSC, CD45+ CD11b+ Ly6G- Ly6C hi), CD8 T cell (CD45+ CD3+ CD8a+), and CD4 T cell (CD45+ CD3+ CD8a-) populations. RNA was extracted and transcripts were quantified by the NanoString nCounter Metabolic Pathways Panel.

Expression data from granulocytic MDSC (G-MDSC) and neutrophils

Project description:Myeloid derived suppressor cells (MDSC) playing the immune suppressive roles in tumor bearing host consists of two major subsets of granulocytic and monocytic cells. Granulocytic MDSC (G-MDSC) express CD11b+ Gr-1high Ly6G+ Ly6Clow and produce high level of reactive oxygen species (ROS). Interestingly, neutrophils are well known ROS producing cells during immune defensive process and share same surface markers with G-MDSC. These similar features always brought the fundamental questions what’s the difference between G-MDSC and neutrophils but it’s not yet proven clearly. In this study, we examined the gene expression of G-MDSC and neutrophils using Affymetrix microarray G-MDSC (CD11b+Ly6G+Ly6Clow) were purifed from splenocytes in EL4 lymphoma tumor bearing mice by positive selection of Ly6G using microbeads isolation. Neutrophils were purified from ascitic fluids induced after injection of milk protein, casein by negative selection of F4/80 and positive selection of Ly6G using microbeads isolation. Their RNA was extracted and gene expression was analyzed using Affymetrix microarray.

Ly6C monocyte subsets transcriptome analysis from wild type and hyperhomocysteinemic mice

Project description:Murine monocytes (MC) are classified into Ly6Chigh and Ly6Clow MC. Ly6Chigh MC is the pro-inflammatory subset and the counterpart of human CD14++CD16+ intermediate MC which contributes to systemic and tissue inflammation in various metabolic disorders, including hyperhomocysteinemia (HHcy). This study aims to explore molecule signaling mediating MC subset differentiation in HHcy and control mice.Mouse white blood cell were prepared from peripheral blood and stained with antibody against CD11b, Ly6G and Ly6C and subjected for flow cytometry cell sorting. CD11b+Ly6G- cells were selected as MC. MC subsets (CD11b+Ly6G-Ly6Chigh, and CD11b+Ly6G-Ly6Clow) were sorted based on Ly6C levels. The quantification of MC was used flow cytometry analysis for Ly6Chigh and Ly6Clow MC in CT and Cbs-/-. Then, 100 ng mRNA were obtained from 100,000 sorted cells of CT and Cbs-/- (HHcy) mice. Around 30 million reads were achived and 16,487 normalized genes per sample by mRNA-Seq analysis.

Expression data from neutrophils from wild-type and Jdp2-/- mice

Project description:Jdp2 is a member of the AP-1 family and suppresses histone acetyltransferase activity. We used microarrays to examine the gene expression pattern of neutrophil form Jdp2-/- mice. Bone marrow CD11b+Ly6Clo Ly6G+ neutrophils form wild-type and Jdp2-/-mice were sorted by FACS, followed by RNA extraction. Affymetrix microarrays were used to analyze the mRNA expression.

Gene regulation in macrophages from irradiated tumors

Project description:Tumors engender an environment dominated by M2 differentiated tumor macrophages that support tumor invasion, metastases and escape from immune control. In this study, we demonstrate that following radiation therapy of tumors in mice there is an influx of tumor macrophages that polarize towards wound repair and immune suppression. To investigate changes in the phenotype of tumor macrophages following radiation therapy, we FACS sorted tumor macrophages from Panc02 tumors. We have previously shown that we can distinguish mature tumor macrophages from immature myeloid and MDSC populations by expression of Gr1 and IA (MHC class II). To isolate these sub-populations, we first gated CD11b+ cells in the untreated or irradiated tumors, then sorted the CD11b+IA+ macrophage population and the CD11b+Gr1hi MDSC population. Cytospins of the sorted populations demonstrates that the CD11b+Gr1hi MDSC predominantly have a granulocyte morphology and the CD11b+IA+ cells have a macrophage morphology in both the untreated and irradiated tumors. RNA was purified from CD11b+IA+ macrophages from untreated or irradiated tumors 1 day or 7 days following radiation therapy and Gene Expression Microarray analysis was performed. There are untreated and irradiated samples at time points 1 day and 7 days following radiation therapy. The experiment was repeated in entirety, generating a second gene array sample for each. For analysis, the untreated samples of 1 day and 7 days were grouped together.
