Gene expression profile of regulatory T cells (Tregs) isolated from visceral adipose tissue and lymph nodes of mice sufficient and deficient of Pparg expression in Tregs

ABSTRACT: We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To establish the role of Pparg in shaping the VAT Tregs gene profile and cell dynamics, Tregs from lymph nodes and visceral adipose tissue of mice sufficient and deficient of Pparg expression in Tregs were double sorted for microarray analysis.

Gene expression profile of regulatory T cells (Tregs) isolated from visceral adipose tissue and lymph nodes of mice sufficient and deficient of Pparg expression in Tregs

Project description:We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To establish the role of Pparg in shaping the VAT Tregs gene profile and cell dynamics, Tregs from lymph nodes and visceral adipose tissue of mice sufficient and deficient of Pparg expression in Tregs were double sorted for microarray analysis. All gene expression profiles were obtained from highly purified (double-sorted) T cell populations sorted by flow cytometry. To reduce variability, cells from multiple mice were pooled. Triplicates were generated for all groups. Raw data were preprocessed with the RMA algorithm in GenePattern and averaged expression values were used for analysis.

Expression data of Pioglitazone- or vehicle-treated CD4+FoxP3- T cells transduced with Foxp3+/- Pparg1 (or Pparg2)

Project description:We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To explore the contribution of Pparg1 and 2 in the generation of the VAT Tregs-specific gene signatures, CD4+FoxP3- T cells were transduced with Foxp3+/- Pparg1 (or Pparg2), treated with Pioglitazone or vehicle, and double sorted for microarray analysis. All gene expression profiles were obtained from highly purified (double-sorted) T cell populations sorted by flow cytometry. To reduce variability, cells from multiple mice were pooled. Triplicates were generated for all groups. Raw data were preprocessed with the RMA algorithm in GenePattern and averaged expression values were used for analysis.

Effect of PPARg on the transcriptome of regulatory T cells (Tregs)

Project description:To investigate the role of PPARg in Tregs, we established conditional knockout mice that lack PPARg specifically in Tregs (Ppargf/f Foxp3-Cre mice).

Transcriptional profiling of Visceral Adipose Tissue (VAT) and splenic Tregs over circadian time

Project description:We isolated VAT and splenic Tregs every four hours over twenty-four hours and reported their transcriptome. We found that the expression of core clock genes was upregulated and rhythmic in VAT Tregs compared with splenic Tregs. Additionally, we described hundreds of other genes with rhythmic expression over time.

Transcriptional profiling of Bmal1WT and Bmal1KO Tregs

Project description:We isolated visceral adipose tissue (VAT) Tregs from Foxp3.YFP-Cre Bmal1WT or Foxp3.YFP-Cre bmal1flox mice fed a normal lean diet or a high-fat diet. VAT Tregs were also sorted after adoptive transfer. We found that Bmal1KO Tregs are more activated in lean mice, after 4 weeks HFD and after adoptive transfer, but loseVAT Treg signature after 16 weeks of high-fat diet feeding.

Gene expression of visceral adipose regulatory T cells from mice with specific deletion of insulin receptor in the cells

Project description:Visceral adipose tissue (VAT) regulatory T cells (Tregs) control inflammation and metabolism. Diet-induced obesity causes hyperinsulinemia and diminishes VAT Treg number and function, but whether these two phenomena were mechanistically linked was unknown. We hypothesized that excessive insulin signaling in obesity negatively impact VAT Tregs. Using Treg-specific insulin receptor deletion (Foxp3-cre;Insr-fl/fl) mice, we compared the gene expression of VAT Tregs from control and knockout mice in obesity and aging, two models of hyperinsulinemia. We found that genes associated with Treg functions were altered in Tregs lacking insulin receptor.

Metabolic control in VAT by Tregs through OSM-mediated suppression of adipogenesis

Project description:Regulatory T cells (Tregs) play diverse roles in tissue homeostasis. In visceral adipose tissue (VAT), resident Tregs, enriched with PPARγ, are clonally expanded in a IL-33 dependent manner. However, the tissue-specific functions of VAT Tregs, with unique transcriptome compared to spleen or other peripheral tissues, remain largely unknown. We identified two PPARγ+ mesenchymal stromal cells in VAT (VmSCs), named VmSC4s (PPARγ+Thy1-) and 5s (PPARγ+Thy1+). Lineage-tracing and transcriptome analysis revealled that VmSC4s contain precursors for VmSC5s. We also demonstrated that VAT Tregs directly suppress adipogenic differentation of VmSC5s through Oncostain M (OSM) to promote insulin sensitivity and glucose tolerance. Thus, VAT-Treg-derived OSM and VmSCs-displayed OSMR maintain tissue homeostasis via limiting the differentiation of dysfunctional adipocytes, which provide therapeutic targets for treating obesity and diabetes.

Transcriptional profiling of Regulatory T (Treg) cells and CD4+ conventional T (Tconv) cells from vTreg53 TCR transgenic and PPARg reporter mice

Project description:We reported transcriptional characterization of Treg and Tconv cells from thymic, splenic, and visceral adipose tissue (VAT) of vTreg53 TCR transgenic mice and control littermates. We examined the effect of Foxp3 on splenic and VAT CD4+ T cell transcriptome. We profiled gene expression in a novel PPARg+ splenic Treg population. We uncovered that the characteristic phenotype of VAT Treg cells was acquired in two stages.

Single-cell expression profiling of visceral adipose tissue and splenic CD4+ T cells from Treg-bmal1WT and Treg-bmal1KO mice at ZT0 and ZT12.

Project description:we reported single-cell gene expression of CD4+ T cells from the visceral adipose tissue of from male Foxp3-Cre.YFP bmal1WT or Foxp3-Cre.YFP bmal1flox/flox mice, and from spleen from bmal1WT mice, at ZT0 or ZT12. We found that VAT Tregs could be subdivided into five subtypes: p1 ST2+, p2 ST2+, Tbet+, IL18r+ and resting clusters. We found diurnal variation within the ST2+ subgroups, where the more activated p1 ST2+ Tregs were more represented at ZT0 in WT VAT Tregs. Such variations were not observed in splenic Tregs. In contrast, bmal1KO VAT Tregs were were enriched in the ST2+ Tregs, and had a constitutively high proportion of the p1 ST2+ subtype at ZT0 and ZT12.
