TCF-1 regulation of CD8+ T cell chromatin accessibility

Project description:CD8+ T cell differentiation traditionally results in the emergence of two subsets, Tc1 cells that produce interferon (IFN)-gamma and memory cells that mediate immune protection against pathogen infections. More recently, it has emerged that other specialized CD8+ T cell populations develop in immune responses and are critical to orchestrate complete immune protection. These subsets include tissue-resident memory (Trm) T cells, follicular cytotoxic T cells and two CD8+ T cell subsets that produce interleukin (IL)-17, namely, mucosal-associated invariant T (MAIT) cells and Tc17 cells. Here we investigated the role of TCF-1 in CD8+ T cell differentiation by using Assay for Transposase-Accessible Chromatin sequencing (ATAC-Seq) to determine the chromatin accessibility landscape of CD8+ T cells and how this is controlled by TCF-1. Loss of TCF-1 was associated with global changes in the chromatin architecture in CD8+ T cells leading to increased accessibility of Rorc and Tc17 effector genes IL-17a and IL-17f in Tc17 cells. In contrast, we observed reduced accessibility of Tbx21, Eomes and Irf4 loci in Tc17 cells, genes normally required for the induction of Tc1 and memory CD8+ T cells

Transcriptomic analysis of TCF-7 cKO CD8 T cells

Project description:T Cell Factor-1, encoded by TCF-7, is a transcription factor that plays an essential role during T cell development and differentiation. In this manuscript we utilized a pre-clinical model provided evidence that TCF-7 is dispensable for the anti-tumor response, and that TCF-7 suppresses key transcriptional factors Eomes and T-bet and molecules responsible for peripheral CD8 T cell cytolytic function. We discovered that TCF-7 regulates NKG2D expression on naïve and activated mouse CD8 T cells, and that peripheral CD8 T cells from TCF-7 cKO utilize NKG2D to clear tumor cells. We also provide evidence that TCF-7 regulates key signaling molecules, including LCK, LAT, ITK, PLC-y1, P65, ERKI/II, and JAK/STATs required for peripheral CD8 T cell persistent function. Our data transcriptomic and protein data uncovered the mechanism of how TCF-7 impacting peripheral CD8 T cell inflammatory cytokine production, CD8 T cell activation, and apoptosis. Our pre-clinical model showed that CD8 T cells from TCF-7 cKO mice did not cause GVHD, but effectively cleared primary tumor cells.

Expression data from WT and TCF-1-deficient memory CD8 T cells

Project description:TCF-1 is an HMG family transcription factor which is known to be activated by the canonical Wnt signaling pathway and modulated by other signals such as those derived from T cell receptor. We found that during CD8 T cell responses, TCF-1 deficiency impaired long-term maintenance of antigen-specific memory CD8 T cells. We used microarrays to detect gene expression changes in memory CD8 T cells caused by TCF-1 deficiency. Host mice that received WT or TCF-1-deficient OT-I CD8 T cells were infected with attenuated Listeria monocytogenes expressing Ova peptide. In memory phase (i.e., more than 80 days post infection), antigen-specific T cells were ioslated by cell sorting. RNA was extracted and hybridized to GeneChip Mouse GENE 1.0 ST arrays (Affymetrix).

Tcf-1 shapes the chromatin landscape of naive T cells

Project description:We investigate the requirement of the transcription factor Tcf-1 for T cell specific accessible elements and gene expression in developing T cells. We examine the impact of Tcf-1 on creating chromatin accessibility related to T cell identity in an unrelated, differentiated cell-type.
