Expression data from cord blood derived CD4+ CD25+ (Treg) and CD4+ CD25- (Thelper) cells, both while resting & after stimulation

ABSTRACT: Here we compare the effects of stimulation on cord blood derived CD4+ CD25+ (Treg) and CD4+ CD25- (Thelper) cells, isolated by MACS protocols & expanded in vitro using dynabeads. Expansion was carried out at a ratio of 3 beads/cell in the presence of 1000units/ml of recombinant human IL2 for 8 days, followed by 3 days of culture without beads. RNA was extracted from resting cells on day 4 after expansion. Stimulated cells were treated with Ionomycin for 2hrs prior to RNA extraction.

Transcription profiling of mouse CD4+ CD25+, CD4+ CD25- CD45RBlow LAG3+ and CD4+ CD25- CD45RBlow LAG3- T cells

Project description:Comparison of gene expression profile of CD4+ CD25+, CD4+ CD25- CD45RBlow LAG3+ and CD4+ CD25- CD45RBlow LAG3- T cells. Naive CD4+CD25-CD45RBhigh T cells were used as a reference for pair comparison with values from the three other subsets.

CD4+ cell transcriptional profiling by RNA sequencing

Project description:<p>We use next generation sequencing to investigate the different transcriptomes of closely related CD4+ T-cells from healthy human donors to elucidate the genetic programs that underlie their specialized immune functions. Six cell types were included: Regulatory T-cells (CD25hiCD127low/neg with >95% FOXP3+ purity), regulatory T-cells activated using PMA/ionomycin, CD25-CD45RA+ ('naive' helper T-cells), CD25-CD45RO+ ('memory' helper T-cells), activated Th17 cells (>98% IL17A+ purity) and activated IL17-CD4+ T-cells (called 'ThPI'). Poly-T capture beads were used to isolate mRNA from total RNA, and fragment sizes of ~200 were sequenced from both ends on Illumina's genome analyzer. We confirm many of the canonical signature genes of T-cell populations, but also discover new genes whose expression is limited to specific CD4 T-cell lineages, including long non-coding RNAs. Additionally, we find that genes encoded at loci linked to multiple human autoimmune diseases are enriched for preferential expression upon T-cell activation, suggesting that an aberrant response to T-cell activation is fundamental to pathogenesis.</p>

RNA-seq from mice CD4+CD25+ splenocytes

Project description:To better understand the function of CD4+CD25+ splenocytes from different ages, target cells from young(8-week old) aged(18-month old) were sorted with magnetic beads. We then performed gene expression profiling analysis using data obtained from RNA-seq of different cells from different age.

Gene expression profiling of CD4+CD25+Foxp3+ regulatory T cells and CD4+CD25-Foxp3- T cells in the course of Plasmodium yoelii infection of BALB/c mice

Project description:The objective of the present study was to characterize the phenotype of CD4+CD25+Foxp3+ regulatory T cells (Tregs) in the course of parasitic Plasmodium yoelii (P .yoelii) infection of BALB/c mice. Therefore we performed microarray expression analysis of CD4+CD25+Foxp3+ Tregs isolated by FACS from spleens of non-infected mice and from spleens of mice infected with P. yoelii 3 days and 5 days post infection. By comparing the gene expression profiles, we were able to identify molecules which were differentially expressed by Tregs during parasitic infection and thereby might be involved in their immune-suppressive function. Moreover, we included CD4+CD25-Foxp3- T cells from spleens of non-infected and P. yoelii-infected mice in our analysis. It was proposed that immune-suppressive CD4+CD25-Foxp3- T cells might be induced during Plasmodium infection of mice. Thus, detailed gene expression data of these cells in comparison to CD4+CD25+Foxp3+ Tregs would contribute a better understanding in the phenotype. FACS sorted CD4+CD25+Foxp3+ Tregs and CD4+CD25-Foxp3- T cells from pooled spleens of non-infected Foxp3/ eGFP mice (served as reference) and from pooled spleens of P. yoelii infected Foxp3/ eGFP mice 3 days and 5 days post infection were analyzed as single probes.

CD4/CD25 subsets of mouse spleen

Project description:A comparison of CD4+CD25+ and CD4+CD25- splenic T cells. Although both subsets have regulatory T cell activity in an induced transplantation tolerance model, the CD4+CD25+ subsets are apparently 10 fold enriched in regulatory T cells. SAGE analysis is performed and compared both on resting and CD3 activated populations. Keywords: other

Histone H3 Lysine 4 mono-, di- and trimethyl and CTCF in CD4+CD25+CD45RA+ regulatory and conventional CD4+CD25- T-cells

Project description:Analysis of Histone H3 Lysine 4 mono-, di- and trimethyl and the boundary protein CTCF in CD4+CD25+CD45RA+ regulatory T-cells and conventional CD4+CD25- T-cells. To investigate regulatory functions or potential new transcription start sites in Treg and Tconv cells, we investigated the associated histone modifications. Mono- and dimethylation of histone 3 lysin 4 (H3K4) were previously shown to mark enhancer regions, whereas H3K4 trimethylation generally associates with transcription start sites. At imprinted loci, binding of the insulator protein CTCF, which restricts or directs enhancer-promoter interactions, is often regulated by DNA-methylation. Therefore we performed ChIP-on-chip experiments (chromatin immunoprecipitation followed by microarray hybridization; samples were amplified with ligation mediated PCR [see label protocol for the procedure] prior to labeling) for mono- di- and trimethylation of histone 3 lysin 4 and of CTCF in expanded Treg and Tconv cells. Keywords: ChIP-on-chip ChIP-on-chip experiments for H3K4 mono-, di- and trimethyl and CTCF in CD4+CD25+CD45RA+ regulatory T-cells and conventional CD4+CD25- T-cells were co-hybridizied with the input. Three biologiacal replicates (rep1-3) were performed for every histone mark, two CTCF (rep1 and rep2).

CD4+ T cell response to IFNa in vitro

Project description:Here we analyzed the transcriptional response to IFNa in activated CD4+ T cells in vitro. We found robust induction of ISGs as early as 2hrs. Splenic CD4+ T cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were activated with CD3/28 beads for 48hrs and thereafter cultured with IFNa (100U/ml) for 2hrs or 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays.
