Expression data from healthy control human peripheral blood mononuclear cells (PBMC) treated with wild-type IL-2 or F42K

ABSTRACT: IL-2 mutant (F42K) is a variant of IL-2 that binds preferentially to the lower affinity IL-2RÎ²Î³ and has minimal binding to CD25, on Tregs, effector NK and T-cell subsets. Our recent study has uncovered that in contrast to WT IL-2, F42K did not efficiently induce the expansion of highly suppressive ICOS+ Tregs in PBMC from healthy controls and melanoma patients whereas it did promote the expansion of NK cells. We used microarray to study the differences of gene profiles induced by wild-type (WT) IL-2, F42K and IL-15 when treated on freshly isolated human peripheral blood mononuclear cells (PBMC) from healthy control. Human peripheral blood mononuclear cells (PBMC) were isolated from buffy coat and were stimulated with 0.4nM WT IL-2, F42K or IL-15 for 24 hr. Total RNA was extracted from each WT IL-2, F42K and IL-15 treated PBMCs and Sense RNA was reverse-transcribed via RT reaction into DNA and labeled with biotin using Affymetrix labeling kits and hybridized on human Affymetrix microarray chip.

Runx3 function in splenic NK cells (IL-2 or IL-15)

Project description:NK cells are innate immune cells that recognize and kill foreign, virally-infected and tumor cells without the need for prior immunization. NK expansion following viral infection is IL-2 or IL-15-dependent. To identify Runx3 responsive genes, NK cells were isolated from spleen of WT and Runx3-/- mice . Ten samples (5 WT and 5 Runx3-/-) of freshly isolated NK cells were separately obtained from individual mice. Cells were cultured for 7 days with IL-2 or IL-15.

Runx3 function in splenic NK cells

Project description:NK cells are innate immune cells that recognize and kill foreign, virally-infected and tumor cells without the need for prior immunization. NK expansion following viral infection is IL-2 or IL-15-dependent. To identify Runx3 responsive genes, NK cells were isolated from spleen of WT and Runx3-/- mice . Six samples (3 WT and 3 Runx3-/-) of freshly isolated NK cells (resting) were separately obtained from individual mice.

Runx3 function in splenic NK cells activated in vivo by IL-15.

Project description:NK cells are innate immune cells that recognize and kill foreign, virally-infected and tumor cells without the need for prior immunization. NK expansion following viral infection is IL-2 or IL-15-dependent. To identify Runx3 regulated genes, NK cells were isolated from spleen of IL15/Ra injected WT and Runx3-/- mice and sorted to obtain 3 subpopulations of immature (CD27) and mature (DP and CD11c) NK cells.

Expression data from peripheral blood mononuclear cell in patients with type 1 diabetes compared with normal controls

Project description:Type 1 diabetes mellitus (T1D) is a common autoimmune disease mediated by autoimmune attack against pancreatic b cells.Dys-regualtion of the component of peripheral blood mononuclear cells (PBMCs), including T-cells and B-cells, and smaller amounts of NK cells and dendritic cells, have all been implicated in this process This study sought to identify T1D associated differently expressed genes in the peripheral blood mononuclear cell (PBMC). Peripheral blood mononuclear of newly diagnosed type1 diabetes patients and normal controls were purified by LymphoprepTm gradient purification according to the manufacturer’s instructions (Axis-Shield PoC AS, Oslo, Norway) for futher microarray analysis.

A Cell-based Systems Biology Assessment of Human Blood to Monitor Immune Responses After Influenza Vaccination

Project description:Systems biology is an approach to comprehensively study complex interactions within a biological system. Most published systems vaccinology studies have utilized whole blood or peripheral blood mononuclear cells (PBMC) to monitor the immune response after vaccination. Because human blood is comprised of multiple hematopoietic cell types, the potential for masking responses of under-represented cell populations is increased when analyzing whole blood or PBMC. To investigate the contribution of individual cell types to the immune response after vaccination, we established a rapid and efficient method to purify human T and B cells, natural killer (NK) cells, myeloid dendritic cells (mDC), monocytes, and neutrophils from fresh venous blood. Purified cells were fractionated and processed in a single day. RNA-Seq and quantitative shotgun proteomics were performed to determine expression profiles for each cell type prior to and after inactivated seasonal influenza vaccination. Our results show that transcriptomic and proteomic profiles generated from purified immune cells differ significantly from PBMC. Differential expression analysis for each immune cell type also shows unique transcriptomic and proteomic expression profiles as well as changing biological networks at early time points after vaccination. This cell type-specific information provides a more comprehensive approach to monitor vaccine responses.

Project description:Aberrant gene expression between HCC tumor tissues, histologically normal adjacent liver tissues and peripheral blood mononuclear cell (PBMC) samples from healthy individuals and patients with pancreatic carcinoma, gastric carcinoma and HCC were identified using Affymetrix gene arrays. A 13-member HCC-specific gene signature was identified and validated via custom-designed quantitative multiplexed gene expression analysis using the GenomeLab GeXP Genetic Analysis System (GeXP). Peripheral blood mononuclear cell (PBMC) from healthy individuals, patients with pancreatic carcinoma, gastric carcinoma, and HCC were isolated and total RNA was extracted for Affymetrix gene microarray analysis.
