Human peripheral blood CD4+ T cell subsets

ABSTRACT: Cells were isolated from healthy human donors (n=2). Unstimulated cells. Cells were stained with CD4, CD45RA, CCR7 and CXCR7. Using flow cytometry, 4 CD4+ T cell populations were sorted: (1) Naïve (CD45RA+CCR7+CXCR5-), (2) Central memory (CD45RA-CCR7+CXCR5-), (3) Effector memory (CD45RA-CCR7-CXCR5-) and (4) CXCR5+ cells (CD45RA-CCR7-CXCR5+) RNA were extracted from sorted cells and hybridized on Affymetix HU133Plus2 chips. Each population were repeated on different donors such that n=2.

CXCR5 expressing human central memory CD4 T cells and their relevance for humoral immune responses.

Chevalier Nina N Jarrossay David D Ho Edwin E Avery Danielle T DT Ma Cindy S CS Yu Di D Sallusto Federica F Tangye Stuart G SG Mackay Charles R CR

Journal of immunology (Baltimore, Md. : 1950) 20110406 10

High expression of CXCR5 is one of the defining hallmarks of T follicular helper cells (T(FH)), a CD4 Th cell subset that promotes germinal center reactions and the selection and affinity maturation of B cells. CXCR5 is also expressed on 20-25% of peripheral blood human central memory CD4 T cells (T(CM)), although the definitive function of these cells is not fully understood. The constitutive expression of CXCR5 on T(FH) cells and a fraction of circulating T(CM) suggests that CXCR5(+) T(CM) may ...[more]

Nanostring Human v3 miRNA Assay on CD4+ T naïve, central memory and effector memory total RNA

Project description:Buffy coats from four independent human donors were enriched for CD4+ cells using MACS CD4 beads and LS columns. Cells were subsequently sorted into Naïve, Central Memory and Effector Memory using following markers: Naive: CD4+CD25–CD45RA+CCR7+; Central Memory: CD4+CD25–CD45RA–CCR7+; Effector Memory: CD4+CD25-CD45RA-CCR7-. Total RNA from these cell subsets was extracted and 100ng was used for Nanostring SPRINT run according to manufacturer's instructions. Overall aim of the experiment is assessing the expression level of human T helper cell miRNome.

Expression of miRNAs in human ex-vivo CD8+ T cell subsets

Project description:The aim was to assess miRNA expression in 3 human ex-vivo CD8+ T cell subsets which span from antigen inexperienced cells (NaM-CM-/ve) to early memory cells (central memory, Tcm) and later stage memory cells (effector memory, Tem) CD8+ T cells were sorted on a FACS Aria II machine. N = naM-CM-/ve = CD8+, CCR7+, CD45RA+, CD45RO-, Tcm = central memory = CD8+, CCR7+, CD45RA-, CD45RO-,Tem= effector memory = CD8+, CCR7-, CD45RA-, CD45RO+ PBMC were isolated from 3 healthy human donors and sorted by FACS into 3 CD8+ T cell subsets. Total RNA was purified using the miRVANA kit (Ambion)

Transcriptional analysis of naïve and central memory CD4 and CD8 T cells from healthy subjects treated with IL-27

Project description:To examine the broad impact of IL-27 on human T lymphocytes, we performed a microarray analysis assessing >20,000 well annotated genes on purified naïve (CD45RA+CD45RO-CCR7+) and central memory (CD45RA-CD45RO+CCR7+) CD4+ and CD8+ T cells from three healthy donors that were activated in vitro (plate bound anti-CD3 and soluble anti-CD28) in the presence or absence of human recombinant IL-27 (100 ng/mL). Our goal was to investigate the impact of interleukin-27 on the gene expression profil of human CD4 and CD8 T lymphocytes.

Transcriptional analysis of human blood CXCR5+ CD4 T cell populations

Project description:The vast majority of currently licensed human vaccines work on the basis of long-term protective antibody responses. Generation of long term humoral immunity is a complex process predominantly dependent on germinal centers and CD4 T cell help to B cells. Follicular helper T cells (Tfh) are the specialized CD4 T cells for B cell help. However, whether such cells develop memory in humans and can be tracked in human blood has been enigmatic. We identified a subpopulation of blood CXCR5+ PD-1+CXCR3- resting CD4 T cells that are most related to Tfh cells of lymphoid tissue by gene expression profile and phenotype. Functional analysis showed that these memory Tfh cells were specialized for helping B cells. Moreover, these cells correlate with a clinically important outcome: development of potent neutralizing antibodies against HIV in HIV+ individuals. CD4 T cells were enriched from fresh blood of 5 normal donors by magnetic beads negative selection. Following enrichment, CD14-CD16-CD19-CD8-CD4+CD45RA- cells from each donor were FACS sorted into the following 5 populations: CXCR5-, CXCR5+PD1+CXCR3-, CXCR5+PD1+CXCR3+, CXCR5+PD1-CXCR3-, and CXCR5+PD1-CXCR3+. The gene expression profile of each cell population was determined.

Profiling of naÃ¯ve and memory Tregs

Project description:Changes in Treg function are difficult to quantify due to the lack of Treg-exclusive markers in humans and the complexity of functional experiments. We sorted naive and memory human Tregs and conventional T cells, and identified genes that identify human Tregs regardless of their state of activation. We developed this Treg signature using Affymetrix human genome U133A 2.0 microarrays. To generate Tregs and Tconvs in multiple states of activation, naÃ¯ve (CD4+CD25hiCD45RA+) and memory (CD4+CD25hiCD45RA-) Tregs, and naÃ¯ve (CD4+CD25-CD45RA+) and memory (CD4+CD25-CD45RA-) Tconvs were sorted from blood of 7 healthy adults and RNA was isolated ex vivo or after stimulation for 40h, promoting activation-induced FOXP3 in Tconvs. The gene-expression profile of the eight cell subsets was analyzed. 7 adult healthy control samples were sorted into 4 subsets: naÃ¯ve (CD4+CD25hiCD45RA+) and memory (CD4+CD25hiCD45RA-) Tregs, and naÃ¯ve (CD4+CD25-CD45RA+) and memory (CD4+CD25-CD45RA-) Tconvs. These were used for RNA ex vivo and after 40h stimulation with anti-CD3/CD28 beads to induce an activation phenotype.

Gene expression in healthy and gene deficient human naÃ¯ve CD4+ T cells

Project description:Ascertain the effects of disease-causing gene mutations on the differentiation status of human naÃ¯ve CD4+ T cells in the setting of primary immunodeficiencies. Thus, do CD4+ T cells isolated according to a naÃ¯ve surface phenotype (ie CD4+CD45RA+CCR7+) from healthy donors exhibit a similar gene expression profile as phenotpyically-matched cells isolated from individuals with defined primary immunodeficiencies caused by specific monogenic mutations. NaÃ¯ve CD4+ T cells were isolated from PBMCs of healthy controls or from different PID patients by sort-purifying CD4+CD45RA+CD127+CD25lo cells. Memory CD4+ T cells from healthy controls were isolated as CD4+CD45RA- cells. RNA was extracted, transcribed to cDNA and then gene expression analysis determined using Affymetrix Human Gene 2.0 or Human Gene 2.1 ST microarray chips. Normalisation (robust multichip average), log2 transformation and probe set summarisation were performed for each dataset using Bioconductor packages implemented in the R statistical computing environment, version 3.1.1. Subsequent processing and analyses were carried out using GenePattern modules (available at http://pwbc.garvan.unsw.edu.au/gp/). The datasets were merged, quantile normalised, and batch corrected using the MergeColumns, NormaliseColumns and ComBat modules. Differential gene expression analysis was assessed using LimmaGP. The top 100 differentially expressed genes between normal healthy naÃ¯ve and normal healthy memory T cells, as determined by LimmaGP analysis, were used to filter the combined and batch corrected dataset of naÃ¯ve CD4+ T cells from 7 healthy controls and 19 PID patients, and memory CD4+ T cells from 3 healthy controls. Unsupervised clustering was performed using NMFConsensus and NMF (Brunet et al., 2004).

miR-146a Pulldown-sequencing data

Project description:Human CD4+ Total memory cells (CD4+CD25-CD45RA-CCR7+/-) were activated with anti-CD3/anti-CD28 antibodies and transfected with biotinylated miR-146a mimic or biotinylated mimic negative control by Exiqon. After 24h cells were lysed and miRNA:mRNA complexes pulled-down with streptavidin agarose O/N at 4°C. RNA was then purified using TRI-reagent and RNA zymospin columns. Four independent donors were used for this experiment. Total RNA was sequenced in 2 lanes, paired ends. This experiment is assessing direct targets bound by miR-146a in human T cells.
