Expression data from CD11c+ mDCs in HIV infection

ABSTRACT: 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.

Comparison of human plasmacytoid dendritic cells and monocyte-derived dendritic cells

Project description:Transcriptome analysis was conducted to investigate the gene expression profiles of pDCs using bulk RNA-sequencing (RNA-seq). Peripheral blood mononuclear cells (PBMCs) from healthy donors (n=3) were stained with lineage markers (CD3, CD14, CD16, CD19, and CD56), and pDCs were identified via flow cytometry (fluorescence-activated cell sorting [FACS]) based on the co-expression of IL-3R (CD123) and BDCA-2 (CD303). mDCs were identified using CD11c and sorted from the same PBMC donor as a control. After sorting, mRNA was extracted from the sorted cells, including mDCs and pDCs. The whole transcriptome profile was analyzed via RNA-seq.

Single-cell RNA-Seq of entire ventricles of C57BL/6J and B6.Rag2del mice after myocardial infarction

Project description:We compared the cellular and molecular outcome following permanent LAD ligation in wildtype and T- and B cell deficient Rag2del mice. Our results demonstrate that the significant changes in the cardiac immune response following myocardial infarction (MI). 8-12 weeks old, male and female C57BL/6J mice (Charles River, Wilmington, MA, USA) and B6.Rag2del mice (Jackson laboratory, Bar Harbor, ME, USA) were used for this study. Seven days after MI, entire mouse ventricles were isolated and enzymatically digested. Cells were then labelled with CD45 magnetic beads (Miltenyi Biotec, Germany) and positively enriched using the AutoMACS instrument (Miltenyi Biotec, Germany). Viable macrophages/monocytes (CD45+CD11b+CD11c-DAPI-Lactadherinlo), dendritic cells (CD45+CD11b+CD11c+ DAPI-Lactadherinlo), and NK cells (CD45+CD11b-CD11c+NK1.1+ DAPI-Lactadherinlo) were then sorted on the BD FACSAriaTM IIIu (Becton Dickinson, Franklin Lakes, NJ, USA) roughly in a 1:1:1 ratio into DMEM containing 10% FCS before processing for 10× Genomics single-cell RNA sequencing (scRNA-Seq). Libraries for scRNA-Seq were constructed according to the 10× Genomics protocol using the GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. Quality of amplified cDNA and final libraries were evaluated on the 2100 Bioanalyzer instrument (Agilent) using a High Sensitivity NGS Analysis Kit (Advanced Analytical). Subsequent sequencing was conducted on the HighSeq4000 Sequencing System using the HiSeq SBS and HiSeq PE Cluster Kit V4 (all Illumina, San Die-go, CA. USA).

Gene expression pattern of pulmonary CD11c+ cells from middle-aged and young mice.

Project description:Analysis of function of CD11c+ cells from middle-aged and young mice at gene level. This experiment provided insight into the different genes that plays roles in inflammation, immune response and mainly arachidonic acid cascade that are differentiall expressed in CD11c+ cells from middle aged and young mice. Total RNA was isolated from pulmonary CD11c cells (separated using magnetic beads) from middle-aged and young mice

CD38-NAD+ Immuno-Metabolic Axis Regulates Potent Anti-Tumor T Response

Project description:Spleens from the B6 mice were isolated and single cell suspension was made. CD4 T cells were purified from the splenocytes using magnetic bead separation. Briefly, Splenocytes were incubated with biotinylated antibody cocktail consisting of antibodies (Biolegend) to CD19, B220, CD11b, CD11c, NK1.1, Gr1, CD25 CD8. After a wash step, cells were incubated with streptavidin conjugated magnetic particles (BD Biosciences). After washing, CD4 T cells were isolated by applying a magnetic field and removing the untouched cells. Purified CD4 T cells were then activated with plate-bound anti-CD3 plus anti-CD28 in presence of either Th1 or Th17 or Th1/17 polarizing condition for 3 days. Total RNA from the 3 days differentiated Th1, Th17 and Th1/17 cells was isolated using mirVana miRNA isolation Kit (Invitrogen).

Type I IFN-signaling following Pneumocystis (PC)-infection and clearance in CD4 T cell-competent mice

Project description:Type I IFN-signaling suppresses an excessive IFN-{gamma} response and prevents lung damage and chronic inflammation following Pneumocystis (PC)-infection and clearance in CD4 T cell-competent mice. Type I IFN -signaling in pulmonary CD11c+ DCs and alveolar macrophages may prevent chronic inflammation following PC lung infection and clearance by suppressing an excessive IFN-g-response via the induction of SOCS1. IFNAR-/- and wildtype mice were both Pneumocystis infected via itratracheal instillation. Pulmonary CD11c+ cells were isolated from collagen digested lungs at day 7 and day 14 post infection from both wildtype and IFNAR-/- mice using a magnetic cell sorting technique from Miltenyi with CD11c microbeads. Cells from three individual animals per group were isolated and assessed. Comparison of 2 treatment types at 2 timepoints to determine whether type I IFN signaling is initiated in resident and early recruited pulmonary CD11c+ cells following Pneumocystis lung infection and whether this is relevant to the outcome of the inflammatory response during the initiation of clearance.

Comparative Expression Profile of miRNA and mRNA in Primary Peripheral Blood Mononuclear Cells Infected with Human Immunodeficiency Virus (HIV-1) [miRNA]

Project description:Host cells respond to exogenous infectious agents such as viruses, including HIV-1. Studies have evaluated the changes associated with virus infection at the transcriptional and translational levels of the cellular genes involved in specific pathways. While this approach is useful, in our view it provides only a partial view of genome-wide changes. Recently, technological advances in the expression profiling at the microRNA (miRNA) and mRNA levels have made it possible to evaluate the changes in the components of multiple pathways. To understand the role of miRNA and its interplay with host cellular gene expression (mRNA) during HIV-1 infection, we performed a comparative global miRNA and mRNA microarray using human PBMCs infected with HIV-1. The PBMCs were derived from multiple donors and were infected with virus generated from the molecular clone pNL4-3. The results showed that HIV-1 infection led to altered regulation of 21 miRNAs and 444 mRNA more than 2-fold, with a statistical significance of p<0.05. Furthermore, the differentially regulated miRNA and mRNA were shown to be associated with host cellular pathways involved in cell cycle/proliferation, apoptosis, T-cell signaling, and immune activation. We also observed a number of inverse correlations of miRNA and mRNA expression in infected PBMCs, further confirming the interrelationship between miRNA and mRNA regulation during HIV-1 infection. These results for the first time provide evidence that the miRNA profile could be an early indicator of host cellular dysfunction induced by HIV-1. Total RNA isolated from PBMC subjected to 7 days of HIV-1 infection compared to uninfected control PBMC
