Project description:Although the methylation status of histone H3K27 plays a critical role in CD4+ T cell differentiation and its function, the role of Utx, histone H3K27 demethylase, in the CD8+ T cell-dependent immune response remains unclear. We therefore generated T cell-specific Utx knockout (Utx KO) mice to determine the role of Utx in CD8+ T cells. Wild-type (WT) and Utx KO mice were infected with Listeria monocytogenes expressing OVA to analyze the immune response of Ag-specific CD8+ T cells upon primary and secondary infections. There was no significant differences in the primary expansion of Ag-specific CD8+ T cells between WT and Utx KO mice. However, Utx deficiency resulted in an increased secondary expansion of Ag-specific CD8+ T cells. Adoptive transferred Utx KO CD8+ T cells resulted in increased numbers of CD127hi KLRG1lo memory precursors in the primary expansion and larger numbers of memory cells. We observed a decreased gene expression of effector-associated transcription factors, including Prdm1 encoding Blimp1, in Utx KO CD8+ T cells upon primary infection. We confirmed that the tri-methylation level of histone H3K27 in the Prdm1 gene loci in the Utx KO cells was higher than in the WT cells. The treatment of CD8+ T cells with Utx-cofactor α-ketoglutarate hampered the memory formation, while Utx-inhibitor GSK-J4 enhanced the memory formation and increased the secondary expansion in WT CD8+ T cells. These data suggest that Utx negatively controls the memory formation of Ag-stimulated CD8+ T cells by epigenetically regulating the expression of genes, including Prdm1. Based on these findings, we identified a critical link between Utx and the differentiation of Ag-stimulated CD8+ T cells upon infection

Project description:UTX gene is localized on the X chromosome, identified as a demethylase on histone H3 lysine 27. Two independent UTX conditional knockout (cKO) embryonic stem cell lines and two UTX knockout (KO) cell lines were cultured on 0.1% gelatin-coated dishes without feeder cells at desity of 1 million cells/10 cm dish. Cells were cultured overnight and collected. Total RNAs were sequentially purified with Trizol (Invitrogen) and RNeasy kit (Qiagen) and analyzed on Mouse Genome 430 2.0 Array (Affymetrix) at NIDDK Microarray Core Facility following standard protocols.

Project description:Pluripotency can be induced in somatic cells by ectopic expression of defined transcription factors, however the identity of epigenetic regulators driving the progression of cellular reprogramming requires further investigation. Here we uncover a non-redundant role for the JmjC-domain-containing protein histone H3 methylated Lys 27 (H3K27) demethylase Utx, as a critical regulator for the induction, but not for the maintenance, of primed and naM-CM-/ve pluripotency in mice and in humans. Utx depletion results in aberrant H3K27me3 repressive chromatin demethylation dynamics, which subsequently hampers the reactivation of pluripotency promoting genes during reprogramming. Remarkably, Utx deficient primordial germ cells (PGCs) display a cell autonomous aberrant epigenetic reprogramming in vivo during their embryonic maturation, resulting in the lack of functional contribution to the germ-line lineage. H3K27me3 and H3K4me3 were measured genome-wide in the following cell types: Utx+/Y (WT) and Utx-/Y (KO) mouse ES cells and mouse embryonic fibroblast (MEF) before and after DOX induction (initiating reprogramming by OSKM factors).

Project description:Epigenetic changes, including histone methylation, control T cell differentiation and memory formation, though the enzymes that mediate these processes are not clear. We show that UTX, a histone H3 lysine 27 (H3K27) demethylase, promotes the generation of T follicular helper (Tfh) cells, a CD4+ T cell subset essential for B cell antibody generation and clearance of chronic viral infections. Mice with T cell specific UTX deletion (UTX TKO mice) had fewer Tfh cells, showed defective germinal center formation, lacked virus-specific IgG production, and were unable to resolve chronic lymphocytic choriomeningitis virus infection. In UTX TKO T cells, decreased expression of IL-6R±, and other Tfh-related loci, was associated with increased H3K27 methylation. Additionally, Turner Syndrome subjects, who are predisposed to chronic ear infections, have reduced UTX expression in immune cells and decreased Tfh frequency. Thus, we identify a critical link between UTX in T cells and immunity to infection. Mice were infected with chronic LCMV and sorted for Tfh on day 21 pi (sorted for: CD4+CXCR5+CD62Llo T cell).

Project description:Persistent virus infections can cause pathogenesis that is debilitating or lethal. During these infections, virus-specific T cells fail to protect due to weakened antiviral activity or failure to persist. These outcomes are governed epigenetically, though it is unknown which enzymes contribute to T cell loss or impaired function over time. Here, we show that T cell receptor-stimulated CD8+ T cells increase their expression of UTX (Ubiquitously transcribed Tetratricopeptide repeat, X-chromosome), an enzyme involved in demethylating histone-3 lysine-27 (H3K27), and reduce genome-wide H3K27-me3. UTX limits the frequency and durability of virus-specific CD8+ T cells during chronic lymphocytic choriomeningitis virus (LCMV) infection in mice by promoting inhibitory receptor expression and apoptosis. UTX also increases effector gene expression to improve CTL-mediated protection, a process corresponding to reduced H3K27me3 at effector gene bodies. Thus, UTX guides gene expression patterns in CD8+ T cells, promoting antiviral activity while reducing CD8+ T cell durability.
