Project description:CD4+ T cells can differentiate into multiple effector subsets but the potential roles of these subsets in anti-tumor immunity have not been fully explored. We sought to study the impact of CD4+ T cell polarization on efficacy of tumor rejection in a model closely mimicking human disease where the target antigens are often non-mutated tissue differentiation self-antigens. We generated a new transgenic mouse model in which CD4+ T cells recognize a novel epitope in tyrosinase-related protein 1 (TRP-1), an antigen that is expressed by normal melanocytes and B16 murine melanoma. We found that cells could be robustly polarized into Th0, Th1 and Th17 subtypes in vitro, as evidenced by cytokine, chemokine, and adhesion molecule profiles as well as by surface markers, suggesting the potential for differential effector function in vivo. Contrary to the current view that Th1 cells play the most important role in tumor rejection, we found that Th17-polarized cells were superior in mediating destruction of advanced B16 melanoma. Unexpectedly, their therapeutic effect was critically dependent on IFN-γ production, while depletion of IL-17A and IL-23 had little impact. Taken together, these data indicate that the appropriate in vitro polarization of effector CD4+ T cells is decisive for the successful tumor eradication. This principle should be taken under consideration in the design of future clinical trials involving adoptive transfer-based immunotherapy of human malignancies. Two-condition experiment: RNA from TRP-1 transgenic mouse lymphocytes polarized to be either Th1 or Th17 were compared to cells polarized to be Th0.

Project description:We compared the methylated and non-methylated regions in the genome of ex vivo-isolated naive CD4+ T cells, Th1 cells, Th17 cells and regulatory T cells by methyl-CpG binding domain protein sequencing (MBD-seq). Naive T cells and Th1 cells share more methylated regions than naive T cells and Th17 cells or Th1 and Th17 cells. However, analysis of the non-methylated regions revealed the highest similarity between Th1 and Th17 cells. Another aim was the analysis of the Th17 lineage on the basis of the methylome. We searched for regions absent in the methylome of Th17 but present in naive T cells, Th1 cells and regulatory T cells. Here, we identified differential methylation in the loci of Il17a, Chn2, Dpp4 and Dclk1. CD4+ T effector cells were prepared ex vivo, stimulated with PMA/Ionomycin, subjected to a comercially available cytokine secretion kit (IL-17A and IFNg), stained by adding fluorescence-labeled antibodies against CD3, CD4 and CD45RB and sorted by flow cytometry. We sorted naive CD4+ T cells (CD3+CD4+CD45RB_high), Th1 cells (CD3+CD4+CD45RB_low_IFNg+IL17A-), Th17 cells (CD3+CD4+CD45RB_low_IFNg-IL17A+) and regulatory T cells (CD3+CD4+CD25++).

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.

Project description:T-helper (Th) lineages have been generated in vitro by activating CD4 cells with anti-CD3/CD28 antibodies during polarization. Physiologically, however, the generation of Th lineages is by activation with the specific antigen presented by antigen-presenting cells (APC). Here, we used TCR-transgenic mice to compare the phenotypes of Th1, Th9 and Th17 lineages when generated by either one of the two activation modes. Lineage Th cells specific against hen egg lysozyme (HEL), were adoptively transferred into recipient mice transgenically expressing HEL in their lens. Remarkable differences were found between lineages of Th1, Th9, or Th17, generated by either one of the two modes in their capacities to migrate to and proliferate in the recipient spleen and, importantly, to induce inflammation in the recipient mouse eyes. Substantial differences were also observed between the lineage pairs in their transcript expression profiles of certain chemokines and chemokine receptors. Surprisingly, however, close similarities were observed between the transcript expression profiles of lineages of the three phenotypes, activated by the same mode. Furthermore, Th cell lineages generated by the two activation modes differed considerably in their pattern of gene expression, as monitored by microarray analysis, but exhibited commonality with lineages of other phenotypes generated by the same activation mode. This study thus shows that (i) Th lineages generated by activation with anti-CD3/CD28 antibodies differ from lineages generated by antigen/APC and (ii) the mode of activation determines to a large extent the expression profile of major transcripts NaM-CM-/ve CD4+ T cells purified from spleen and lymph node cells of 3A9 mice were activated and polarized toward Th1, Th9, and Th17 lineages, under either plate bound anti-CD3/anti-CD28 (PBAB) or APC presented HEL protein (HA).

Project description:T cells from the spleen of a mixed-gender pool of four double-transgenic 2D2 (TCRMOG) x IgHMOG mice (OSE) mice, which spontaneously develop experimental autoimmune encephalomyelitis (EAE), were used to derive TH1- and TH17-polarized cells, as described in https://doi.org/10.1371/journal.pone.0015531. Here, expression was compared, first, between TH1 and naïve TH0 and, second, between TH17 and naïve TH0 cells.
