Project description:To test whether human in vitro primed Th9 cells recapitulate the core pathogenic Th2 cell phenotype, we differentiated naïve T cells into Th1 (IL-12), Th2 (IL-4), Th9 (IL-4+TGF-β), and iTreg (TGF-β). After 7 days transcriptomic profiling by bulk RNA-seq was performed.

Project description:We next sought to identify the transcriptional program that differentiates IL-9+Th2 cells from “conventional” Th2 cells. To this end, we selected representative Th1, Th17, Th2, and IL-9+Th2 clones (Figure 5A) and determined their transcriptome in the resting state and at different time points after activation using RNAseq. Peripheral Blood Mononuclear Cells (PBMC) were isolated by Ficoll-Plaque Plus (GE Healthcare, UK) density gradient centrifugation. Human CD4+ T cells were isolated from PBMC by EasySep positive selection kit (Stemcell Technologies) according to manufacturer’s instruction. Positively selected CD4+ T cells were washed with PBS and stained for subsequent Th cell subset sorting. Memory Th cell subsets were sorted to over 90% purity according to their expression of chemokine receptors from CD45RA-CD25-CD8-CD3+ cells: Th1(CXCR3+CCR8-CCR6-CCR4-), Th2 (CXCR3-CCR8-CCR6-CCR4+), Th17 (CXCR3-CCR8-CCR6+CCR4+), Th9 (CXCR3-CCR8+CCR6-CCR4+). Single cell Th subset clones were directly sorted into 96well plate according to their expression of chemokine receptors (see above). Single cell clones were expanded and maintained by periodic restimulation with PHA (phytohaemaglutinine, 1 µg/ml, Sigma-Chemicals) and irradiated allogenic feeder cells (5x104/well) in culture medium. T cells were polyclonally activated using beads coated with antibodies against CD3, CD2, and CD28 (T cell/bead = 2:1, human T cell activation/expansion Kit, Miltenyi). Cell cultures were sampled before activation (time 0h) and 2, 4, 6, 9, 12, 24, and 48 hours after activation.

Project description:A variety of CD4+Foxp3+ Treg cell types have been described previously, indicating molecular heterogeneity within the Foxp3+ pool of CD4+ T cells. However, the factors that shape the transcriptomic identities of different Foxp3+ Treg cells are poorly understood. To identify the molecular pathways involved, we isolated CD4+Foxp3gfp+ cells from Th1-rich or Th2-rich environments following chronic Leishmania major or Schistosoma mansoni infection, respectively. Whole genome expression profiling and next generation small RNA sequencing revealed significantly different mRNA and miRNA profiles. In-silico analyses identified miR-10a and miR-182 as âregulatory miRNA hubsâ in CD4+Foxp3+ cells in Th1 and Th2-environments, respectively. Using in vitro and in vivo systems we identified that IL-12/IFNg down-regulated miR-10a and its putative transcription factor, Creb. Importantly, we demonstrated that miR-10a controls a suite of genes that regulate IFNg production in Th1-Treg cells. Also, Treg cells treated with IL-4 increased miR-182 and its putative transcription factor, cMaf. Up-regulation of miR-182 mitigated IL-2 secretion, in part through repression of IL2-promoting genes, including Bach2 and Cd2ap. This study indicates that CD4+Foxp3+ cells are influenced by their environment, and that Th1 or Th2 environments promote distinct miRNA pathways, preserving Treg stability and suppressor function. mouse infection vs. naïve

Project description:T-helper cells differentiate from naïve precursors into multiple lineages, including Th1, Th2, Th17 and inducible Treg, in humans and mice. The identification of each lineage is currently determined by examination of a small number of genes encoding hallmark cytokines and/or transcription factors in both species To gain a better understanding of human T-helper cell function we have performed detailed transcriptional profiling of highly polarized Th1 and Th2 cells in both resting and activated states examining gene and miRNA expression Naïve CD4 positive T-cells were isolated from peripheral blood of three different human donors. Cells were differenitated into Th1 and Th2 cells in vitro for 28 days to achieve homogeneous cell lineages. Samples were taken at resting state or activated for 4 hours with PMA/Ionomycin.

Project description:Gastrointestinal nematode (GIN) is a major economic and health concern is sheep farming. Sheep breeds such as Texel are relatively resistant to GIN than the Suffolk. With the objective to understand the underlying genetic mechanism of resistance and susceptibility at the transcriptomic level, two groups of animal from both the breed were artificially (orally) infected with 30,000 L3 larvae of prominent GIN Teladorsagia circumcincta. Subgroups of animals from each breed were slaughtered on day 0, 3, 7, 14 and 21 of post infection (p.i.). Transcriptomic profiling of abomasal lymph node was performed using RNA-seq. The perturbations in gene expression profiles in both the breeds were evident and Texel showed a more tightly regulated immune response than the Suffolk. The number of differentially expressed (DE) genes between the breeds was highest (437) on un-infected control (day 0) and lowest (173) on day 7 p.i.. Pathway analysis of DE genes identified 3 significant pathways, which involved only more highly expressed genes of Suffolk breed on day 0 and only more highly expressed genes of Texel (with one exception) on day 7 p.i.. The Th1, Th2 and Treg response was evident in response to GIN in Texel and was synchronized, while in Suffolk Th1 response was reduced after infection and pronounced Th2 and Treg was not evident. The study suggests maximum level of transcriptional activity in both breeds on day 7 p.i. and there was a shift of transcriptional activity from Suffolk on day 0 to Texel on day 7 p.i.. Suffolk had a reduced Th1 response with less pronounced Th2 and Treg immune response, while Texel had an active and synchronized Th1/Th2/Treg immune response in response to GIN infection. Abomasal lymph node tissue was taken from control (n=10) and experimentally infected (with T. circumcincta) lambs (n=36) from Texel and Suffolk breed on day 0, 3, 7, 14 and 21 post infection.
