Project description:TOX is a member of the HMG-Box transcription factors and plays important roles in thymic T cell development. Outside of the thymus, however, TOX is also highly expressed by CD8 and CD4 T cells in various states of activation and in settings of cancer and autoimmune disease. In CD4 T cells, TOX has been primarily studied in T follicular helper (TFH) cells where it , along with TOX2 promotes TFH differentiation by regulating key TFH-associated genes and suppressing CD4 cytotoxic T cell differentiation. However, the role of TOX in other Th cell subtypes is less clear. In our study, we show that TOX is expressed in several physiologically-activated Th subtypes and its ectopic expression modestly enhances the in vitro differentiation of Th2 and Treg cells. TOX overexpression also induced the expression of a small number of genes in unpolarized Th cells involved in cell activation (Pdcd1, PD-1), cellular trafficking (Ccl3, Ccl4, Xcl1) and in suppressing inflammation (Il10) that was conserved in multiple Th subtypes. We additionally show that TOX co-occupies these genes with the transcription factor BATF and that TOX-induced expression of IL-10, but not PD-1, is BATF-dependent. Based on these data, we propose a model where TOX regulates Th cell chemotactic genes involved in facilitating dendritic cell-T cell interactions and aids in the resolution or prevention of inflammation through the production of IL-10.

Project description:Tox is a member of the high mobility group (HMG)-Box transcription factors and plays important roles in thymic T cell development. Outside of the thymus, however, Tox is also highly expressed by CD8 and CD4 T cells in various states of activation and in settings of cancer and autoimmune disease. In CD4 T cells, Tox has been primarily studied in T follicular helper (TFH) cells where it, along with Tox2, promotes TFH differentiation by regulating key TFH-associated genes and suppressing CD4 cytotoxic T cell differentiation. However, the role of Tox in other T helper (Th) cell subtypes is less clear. Here, we show that Tox is expressed in several physiologically-activated Th subtypes and its ectopic expression enhances the in vitro differentiation of Th2 and T regulatory (Treg) cells. Tox overexpression in unpolarized Th cells also induced the expression of several genes involved in cell activation (Pdcd1), cellular trafficking (Ccl3, Ccl4, Xcl1) and suppressing inflammation (Il10) across multiple Th subtypes. We found that Tox binds the regulatory regions of these genes along with the transcription factors BATF, IRF4, and JunB and that Tox-induced expression of IL-10, but not PD-1, is BATF-dependent. Based on these data, we propose a model where Tox regulates Th cell chemotactic genes involved in facilitating dendritic cell-T cell interactions and aids in the resolution or prevention of inflammation through the production of IL-10.

Project description:TOX is a nuclear factor essential for the development of CD4+ T cells in the thymus. TOX is found to be aberrantly up-regulated in the skin biopsies and in the blood CD4+ T cells of cutaneous T cell lymphoma. The goal of this study is to identify potential transcriptional targets of TOX in CTCL by comparison between TOX shRNA transfected CTCL cells (Hut78 and HH) and control CTCL cells. Two color experiment. Lentivirus transduced control vector vs. TOX shRNA vectors on Hut78 and HH cell lines. Biological replicates: 3 control replicates, 3 shRNA tansduced replicates for each cell line.

Project description:Although Bach2 plays an important role in regulating the Th2-type immune response, the underlying molecular mechanisms remain unclear. We herein demonstrate that Bach2 associates with Batf and binds to the regulatory regions of the Th2 cytokine gene loci. The Bach2-Batf complex antagonizes the recruitment of the Batf-Irf4 complex to AP-1 motifs and suppresses Th2 cytokine production. Furthermore, we found that Bach2 regulates the Batf and Batf3 expressions via two distinct pathways. First, Bach2 suppresses the maintenance of the Batf and Batf3 expression through the inhibition of IL-4 production. Second, the Bach2-Batf complex directly binds to the Batf and Batf3 gene loci and reduces transcription by interfering with the Batf-Irf4 complex. These findings suggest that IL-4 and Batf form a positive feedback amplification loop to induce Th2 cell differentiation and the subsequent Th2-type immune response, and Bach2-Batf interactions are required to prevent an excessive Th2 response.

Project description:compare wild type and Batf-/- B cells activated for 0 1 or 2 days in vitro. WT or Batf deficient B cells were activated in vitro with LPS for 1 or 2 days, or left untreated. B cells were purified by MACS and activated, harvested and prepped for affymetrix gene expression profiling.

Project description:TOX is selectively expressed in tumor-infiltrating CD8 T cells however the role of TOX in peripheral CD8 T cells is not known. The two goals of this study are to elucidate transcriptional changes between TOX-sufficient and TOX-deficient tumor infiltrating CD8 T cells and to elucidate the molecular program induced by TOX overexpression in peripheral CD8 T cells.

Project description:Subtypes of innate lymphoid cells (ILC), defined by effector function and transcription factor expression, have recently been identified. In the adult, ILC derive from common lymphoid progenitors in bone marrow, although transcriptional regulation of the developmental pathways involved remains poorly defined. TOX is required for development of lymphoid tissue inducer cells, a type of ILC3 required for lymph node organogenesis, and NK cells, a type of ILC1. We show here that production of multiple ILC lineages requires TOX, as a result of TOX-dependent development of common ILC progenitors. Comparative transcriptome analysis demonstrated failure to induce various aspects of the ILC gene program in the absence of TOX, implicating this nuclear factor as a key early determinant of ILC lineage specification.

Project description:Cooperative interactions among transcription factors are essential for gene transcription. We previously showed that NFAT and AP-1 (Fos-Jun) transcription factors cooperate to promote the effector functions of T cells, but that under conditions where it is unable to cooperate with AP-1, NFAT imposes a negative feedback programme of T cell hyporesponsiveness (“exhaustion”). Here we show that BATF and IRF4 cooperate to counter T cell exhaustion. Overexpression of Batf in CD8+ 42 T cells expressing a chimeric antigen receptor (CAR) promoted the survival and expansion of tumour-infiltrating CAR T cells, increased their production of effector cytokines, decreased their expression of inhibitory receptors and the exhaustion-associated transcription factor TOX, and led to the generation of long-lived memory T cells that controlled tumour recurrence. These responses were dependent on the BATF-IRF interaction, since cells expressing a Batf mutant unable to interact with Irf4 did not survive in tumours and did not effectively delay tumour growth. We suggest that BATF overexpression is a therapeutically viable option for improving the anti-tumour responses of CAR TILs, by skewing their phenotypes and transcriptional profiles away from exhaustion and towards increased effector function.
