Time series RNA-seq of Th1 differentiation: The effect of Progesterone on Th1 differentiation?

Project description:T-helper 1 responses are involved in the development of many autoimmune diseases such as Multiple sclerosis (MS). MS is a relapse remitting disease that eventually progresses to a progressive neurodegenerative disease. During pregnancy the relapse rate of MS is significantly reduced with peak reduction during the third trimester followed by an increase in relapse rate post-partum. One of the highest expressed hormones during pregnancy is progesterone. Progesterone has been show to have an inhibiting effect on T-cell activation and been proposed to promote a T-regulatory like cell state. To evaluate the influence of progesterone on the chromatin and gene expressive state of T-helper type 1 cells we differentiated primary human naïve T-cell in the presence progesterone with sampling at 0.5, 1, 2, 6 and 24 hours and performed ATAC-seq and RNA-seq.

P2X7 signaling drives Th1 cell differentiation through metabolic reprogramming for aerobic glycolysis

Project description:This study provides evidence on the molecular mechanisms by which P2RX7 signaling promotes Th1 cell differentiation. P2RX7 induces T-bet expression and aerobic glycolysis in splenic CD4+ T cells that respond to malaria, at a time prior to Th1/Tfh polarization. Cell-intrinsic P2RX7 signaling sustains the glycolytic pathway and causes bioenergetic mitochondrial stress in activated CD4+ T cells. We also show in vitro the phenotypic similarities of Th1-polarized CD4+ T cells that do not express P2RX7 and those in which the glycolytic pathway is pharmacologically inhibited. In addition, ATP synthase blockade in vitro and the consequent inhibition of oxidative phosphorylation, which forces cells to use aerobic glycolysis, is sufficient to promote rapid CD4+ T cell proliferation and polarization to the Th1 profile in the absence of P2RX7. These data demonstrate that P2RX7-mediated metabolic reprograming for aerobic glycolysis is a key event for Th1 cell differentiation and suggest that ATP synthase inhibition is a fundamental mechanism by which P2X7 signaling induces the Th1 response.

Transcription profiling of human CD4+T-cells, Th1/Th2 polarized time-series and primary memory subsets

Project description:Differentiation of CD4+T-cells into effector subsets is a critical component of the adaptive immune system and an incorrect response can lead to autoimmunity or immune deficiency. Cellular differentiation including T-cell differentiation is accompanied by large-scale epigenetic remodeling, including changes in DNA methylation at key regulators of T-cell differentiation. The TET family of enzymes were recently shown to be able to catalyse methylated cytosine (5mC) into 5-hydroxymethylcytosine (5hmC) enabling a pathway of active removal of DNA methylation. Here, we characterize 5hmC, 5mC and transcriptional dynamics during human CD4+T-cell polarisation in a time series approach and relate these changes to profiles in ex-vivo CD4+memory subsets. We observed large-scale remodelling during early CD4+T-cell differentiation which was predictive of subsequent changes during late time points, these changes were also related to disease associated regions which we show can act as functional regulatory elements. This dataset was designed to assess how gene expression changes over time during human CD4+T-cell polarization towards Th1 and Th2. Gene expression was assessed in relationship to 5hmC and DNA methylation levels and changes (see data series), we observed characteristic gene expression for the specific time points and stimuli or cell type and the expression was correlated with gene body 5hmC as well as anticorrelated with promoter DNA methylation levels. This submission contains data from transcription profiling by array of human CD4+T-cells, Th1/Th2 polarized time-series and primary memory subsets. It is part of series containing 5hmC and DNA methylation profiling of the same samples. See related experiments E-MTAB-4685, E-MTAB-4686, E-MTAB-4688, E-MTAB-4689.

This dataset was designed to assess how gene expression changes over time during human CD4+T-cell polarization towards Th1 and Th2. DNA methylation was assessed in relationship to 5hmC levels and changes (see data series), we observed that regions gaining 5hmC early was highly predictive of regions losing DNA methylation during late time points. This submission contains data from the DNA methylation by array profiling of human CD4+T-cells in-vitro polarized towards Th1 and Th2 time-series.
