Gene expression profiles of Foxp3RFP (WT), Foxp3∆EGFPiCre (Foxp3-deficient) and Foxp3∆EGFPiCreRictor∆/∆ (Foxp3-deficient and Rictor deficient) Treg cells.

Project description:Comparaison of the transcriptomes of WT and Foxp3-deficient regulatory T cells from the spleen of females that carried one mutant Foxp3∆EGFPiCre allele and a second competent Foxp3 allele (Foxp3RFP) that also directed the expression of the red fluorescent protein (RFP) . We then extended these studies to elucidate transcriptional pathways altered upon Rictor deletion in ∆Treg cells that may contribute to their improved regulatory function by analyzing the transcriptome of ∆Treg cells isolated from Foxp3∆EGFPiCre/+Rictor∆/∆ females.

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

Human Treg LC-MSMS - Foxp3 drives oxidative phosphorylation and protection from lipotoxicity

Project description:Regulatory T cells (Treg) have been shown to adopt a catabolic metabolic programme with increased capacity for fatty acid oxidation fuelled oxidative phosphorylation (OXPHOS). The role of Foxp3 in this metabolic shift is poorly understood. Here we show that Foxp3 was sufficient to induce a significant increase in the spare respiratory capacity of the cell, the extra OXPHOS capacity available to a cell to meet increased demands on energy in response to work. Foxp3-expressing cells were enhanced in their ability to utilise palmitate for respiration and, in addition, the activity of electron transport complexes I, II and IV were enhanced following Foxp3 expression. Foxp3 also imparts a selective advantage in ATP generation capacity, one that might be exploited as a source of adenosine for functional immunomodulation. In order to explore possible mechanisms for these differences in metabolism we conducted a quantitative proteomics study to compare the contribution of TGFβ and the transcription factor Foxp3 to the Treg proteome. We used quantitative mass spectrometry to examine differences between proteomes of nuclear and cytoplasmic Foxp3-containing CD4+ T cells from various sources with Foxp3- activated CD4 T cells, as well as Treg from human peripheral blood. Gene set enrichment analysis of our proteomic datasets demonstrated that Foxp3 expression is associated with a significant up regulation of several members of the mitochondrial electron transport chain. Not only does Foxp3 influence genes directly concerned with immune function, but also with the energy generating functions of Treg.

Gene expression profiling in Treg cells deficient or mutant in candidate FoxP3 cofactors

Project description:The transcription factor FoxP3 partakes dominantly in the specification and function of FoxP3+ CD4+ T regulatory cells (Tregs), but is neither strictly necessary nor sufficient to determine the characteristic Treg transcriptional signature. Computational network inference and experimental testing assessed the contribution of several other transcription factors (TFs). Enforced expression of Helios or Xbp1 elicited specific signatures, but Eos, Irf4, Satb1, Lef1 and Gata1 elicited exactly the same outcome, synergizing with FoxP3 to activate most of the Treg signature, including key TFs, and enhancing FoxP3 occupancy at its genomic targets. Conversely, the Treg signature was robust to inactivation of any single cofactor. A redundant genetic switch thus locks-in the Treg phenotype, a model which accounts for several aspects of Treg physiology, differentiation and stability. To study the impact of deficiency of candidate FoxP3 cofactors (Xbp1, Eos, Gata1) on the expression of the Treg transcriptional signature, gene expression profiles were generated from purified splenic CD4+CD25hi Tregs of these mutant or knockout mice and their wildtype littermates.

Transcriptional profiling of FOXP3+ Treg cells and corresponding FOXP3-losing cells

Project description:Natural CD4+FOXP3+ regulatory T (Treg) cells constitute a unique T-cell lineage that plays a pivotal role in maintaining immune homeostasis and immune tolerance. Recent studies provide evidence for the heterogeneity and plasticity of the Treg cell lineage. However, the fate of human Treg cells after loss of FOXP3 expression and the underlying epigenetic mechanisms remain to be fully elucidated. Here, we compared gene expression profiles and histone methylation status on two histone H3 lysine residues (H3K4me3 and H3K27me3) of expanded FOXP3+ and corresponding FOXP3-losing Treg cells. DGE assay showed that human Treg cells down-regulated Treg signature genes, whereas up-regulated a set of Th lineages-associated genes, especially for Th2, such as GATA3, GFI1 and IL13, after in vitro expansion. Furthermore, we found that reprogramming of Treg cells was associated with histone modifications, as shown by decreased abundance of permissive H3K4me3 within down-regulated Treg signature genes, such as FOXP3, CTLA4 and LRRC32 loci, although with no significant changes in H3K27me3 modification. Thus, our results indicate that human Treg cells could convert into a Th-like cells upon in vitro expansion, displaying a gene expression signature dominated by Th2 lineage associated genes, and the histone methylation might contribute to such conversion. mRNA profiles of in-vitro-expanded FOXP3+ Treg and FOXP3-losing Treg cells generated by deep sequencing.

Transcription profile of WT and LKB1 (encoded by the gene Stk11)-deficient Treg cells

Project description:LKB1 deficiency in Treg cells impairs their survival, metabolism and suppressive function. To exclude the impact of excessive inflammation on LKB1-deficient Treg cells, we generated mixed bone marrow (BM) chimeras using Foxp3-Cre WT and Foxp3-Cre Stk11 fl/fl BM cells, together with CD45.1+ BM cells. We used microarray to compare the global transcription profile of dornor-derived LKB1-deficient Tregs with WT counterparts.
