Transcriptome analysis of OGT-sufficient and OGT-deficient regulatory T (Treg) cells

Project description:To gain comprehensive insight into the OGT-dependent transcriptional program in Treg cells, we performed RNA-sequencing of isolated YFP+ Treg cells from Foxp3YFP-Cre/wtOgtwt/fl and healthy Foxp3YFP-Cre/wtOgtfl/fl females to avoid secondary changes in gene expression caused by inflammation. We were able to identify 269 differentially expressed genes including 154 downregulated and 115 upregulated with p values less than 0.01, OGT-deficient Treg cells had impaired suppressive function and attenuated IL2/STAT5 signaling pathway.

RNA-seq analysis of transcriptomes of Noc4L deficient and the Nco4L sufficient Treg cells

Project description:To gain in depth transcriptional information about the Noc4L deficient and Noc4L sufficient Tregs, we performed RNA-seq analysis to compare the transcriptomes of Noc4L deficient (CD4+GFP+CD62Lhigh, cKO) and Noc4L sufficient (CD4+GFP+CD62Lhigh, Het) Tregs activated in vitro with Dynabeads for 48 hours or 72 hours. We found ~25 unique genes with differential expression between the Noc4L deficient and Noc4L sufficient Treg cells when activated for 48 hours in vitro. And ~100 unique genes with differential expression between the Noc4L deficient and Noc4L sufficient Treg cells when activated for 72 hours in vitro in two times experiment.

Comparison of mRNA expression pattern between wild-type regulatory T (Treg) cells and Nr4a-deficient Treg cells

Project description:Regulatory T (Treg) cells, as central mediators of immune suppression, play crucial roles in many aspects of immune system physiology and pathophysiology. Treg cells are characterized by a distinct pattern of gene expression, including upregulation of immune-suppressive genes and silencing of inflammatory cytokine genes. However, the molecular mechanisms that establish and/or maintain such gene regulation in Treg cells remain largely unknown. We recently reported that Nr4a family nuclear orphan receptors are essential for the development of Treg cells. The fact that Treg cells maintain high levels of expression of all Nr4a family components suggests that they may also play critical roles beyond Treg cell development. Thus, we compared mRNA expression pattern between wild-type Treg cells and Nr4a-deficietn Treg cells. As a result, we found that expression of 'Treg-signature genes' were globally down regulated in Nr4a-deficient Treg cells. mRNA from wild-type and Nr4a-deficient Treg cells were analyzed.

Genome-wide changes in OGT-deficient mouse liver tissue

Project description:Over a billion people suffer from chronic liver diseases worldwide, which often leads to fibrosis and then cirrhosis. Treatments for fibrosis remain experimental, in part because no unifying mechanism has been identified that initiates liver fibrosis. O-linked β-N-acetylglucosamine (O-GlcNAc) transferase (OGT) plays a pro-survival role under stress in many tissues. Here we report that OGT protects against hepatocyte necroptosis and initiation of liver fibrosis. Decreased O-GlcNAc levels were seen in patients with alcoholic liver cirrhosis and in mice with ethanol-induced liver injury. Liver-specific O-GlcNAc transferase (OGT) knockout (OGT-LKO) mice progressed to liver fibrosis at 10 weeks of age. OGT-deficient hepatocytes underwent necroptosis. These findings identify OGT as a key suppressor of hepatocyte necroptosis and OGT-LKO mice may serve as an effective spontaneous genetic model of liver fibrosis.

Chromatin accessibility analysis of CNS4-sufficient and defincient regulatory T cells, Treg cell precursors, and mature and semimature CD4 single positives

Project description:We have discovered that deletion of a conserved regulatory element upstream of the Foxp3 gene, termed CNS4, results in the abrogation of IL-2 mediated induction of Foxp3 expression during regulatory T cell development. However, the mice still harbor a reduced but functional population of Treg cells. To understand potential compensatory mechanisms driving the differentiation and expansion of regulatory T cells in the absence of CNS4, we profiled CNS4-deficient and -sufficient regulatory T cells, as well as related cell types, from the thymuses of male mice by ATAC-sequencing.

Gene expression profile at single cell level of Treg cells (CD4+CD25+) from healthy Mycfl/flFoxp3Cre/WT female mice, in which Myc-sufficient (WT) and Myc-deficient (KO) Treg cells co-exist

Project description:We performed single cell transcriptome analysis of Treg cells (CD4+CD25+) from healthy Mycfl/flFoxp3Cre/WT female mice, in which Myc-sufficient (WT) and Myc-deficient (KO) Treg cells co-exist due to random inactivation of the X chromosome that harbors the Foxp3 gene.

Expression data from DC-induced Hopx-deficient and sufficient regulatory T cells after immunization

Project description:We found that Hopx is required for the function of DC-induced regulatory T cells in vivo. We used microarrays to identify relevant Hopx-targets in such cells after antigenic re-challenge in vivo. CD25/Foxp3 double positive DC-induced Hopx-deficient and sufficient regulatory T cells were FACS sorted to high purity

Foxo1/3-deficient Treg cells

Project description:Identification of Foxos target genes in Treg cells. Foxo1and Foxo3 are transcription factors of Foxo family. CD4+Foxp3+ Treg cells isolated from wild-type and Foxo1/3-deficient mice were analyzed by global gene expression profiling. Results indicate Foxos regulate expression of a subset of Treg cell signature genes and genes in control of T cell homeostasis, signaling and metabolism. 2 sets wild-type and Foxo1/3-deficient CD4+Foxp3+ Treg cells
