Project description:Because of the extensive data in mice supporting the concept that ST2+ Tregs might have desirable therapeutic properties, including tissue repair function, high suppressive capacity, and enhanced stability, we engineered human blood Tregs to constitutively express ST2 (IL-33R). Here we used RNA sequencing to explore the effects of short-term culture with IL-33 on human ST2-transduced Tregs.

Project description:Foxp3+ regulatory T cells (Tregs) are critical mediators of peripheral tolerance and immune homeostasis. Tregs that express the IL-33 receptor ST2 are enriched in peripheral nonlymphoid tissues and can exert a variety of tissue-specific functions from metabolic regulation within adipose tissue to skeletal muscle repair. However, the relationship between ST2+ and ST2- Tregs within and across different tissues remains unclear. To compare murine ST2- and ST2+ Tregs within and across tissues, we performed RNA sequencing (RNAseq) of ST2-CD44hi and ST2+CD44hi Tregs from blood, spleen, lungs, visceral adipose tissue (VAT), colon, and skin. RNAseq was also performed on ST2- CD44lo CD62L+ Tregs from the spleen and lungs. We found that the tissue microenvironment was the major factor shaping the transcriptome of Tregs across tissues. Across the tissues studied, Treg transcriptomes displayed an ordered hierarchy that may represent graded levels of activation or differentiation across tissues. We also identified a core signature that distinguished ST2+ Tregs from ST2- Tregs across tissues and a large number of differentially expressed genes between ST2- and ST2+ Tregs within individual tissues that could support the tissue-specific adaptation and function of ST2+ Tregs. In summary, our work highlights the unique, tissue-specific phenotype of ST2+ Tregs and reveals a core ST2+ Treg transcriptional signature shared across tissues.

Project description:The effects of IL-33 on ST2+ Treg cells were not studied thouroughly. We FACS-sorted in vitro expanded ST2+ Treg cells from C57BL/6 Foxp3-IRES-mRFP (B6 FIR) mice. We next used RNA-seq techonology to define how recombinant IL-33 (rIL-33) may impact mouse Treg by to assessing the transcriptome of IL-33-stimulated ST2+ Treg cells compared to that of untreated ST2+ Treg cells. Our data revealed that ST2+ Treg stimulated with rIL-33 for 6 hours exhibited increased expression of Il10 and Il13 compared to unstimulated ST2+ Treg cells.

Project description:Colorectal cancer (CRC) was induced in Foxp3/eGFP reporter mice by the azoxymethane/dextran sulphate sodium salt (AOM/DSS) protocol. Mice were injected i.p. with the procarcinogen AOM (12.5 mg/kg of body weight). After 1 week, mice received drinking water supplemented with 2.5% DSS for 5 to 7 days, followed by 2 weeks of regular water. The DSS administration was repeated twice with 2% DSS. Mice were sacrificed at week 11 and lamina propia lymphocytes (LPLs) from the colon were isolated. CD4+FOXP3+ (eGFP+) ST2+ or ST2- Tregs were separated from colonic LPLs of CRC induced mice using a FACSAria II cell sorter. Microarray analysis was performed to analyze if ST2+ FOXP3+ Tregs from the colon of CRC mice present a distinct transcription pattern compared to ST2- FOXP3+ Tregs. By this, the role of ST2 for Treg function during intestinal tumorigenesis should be characterized.

Project description:Regulatory T cells (Tregs) are enriched in the tumor microenvironment (TME) and suppress anti-tumor immunity. However, the origin of tumor-infiltrating (TI) Tregs and the molecular mechanism underlying their TME accumulation are poorly understood. Although IL-33 was reported to regulate the expansion and function of Tregs, its direct role on TI Tregs and its contribution to tumor progression remain uncertain. Firstly, we demonstrated TI Tregs were primarily thymus-derived. More importantly, we found using comparative transcriptome analysis that proliferation-related genes were prominently upregulated in TI Tregs compared with TI CD4+Foxp3− conventional T cells or splenic Tregs of same tumor-bearing mice. One of these genes, ST2, an interleukin-33 (IL-33) receptor, was identified as a potential factor driving Treg accumulation in the TME. Indeed, IL-33-directed ST2 signaling induced the preferential proliferation of TI Tregs and enhanced tumor progression, while genetic deletion of ST2 in Tregs limited their TME accumulation and delayed tumor growth. These data demonstrate the IL-33/ST2 axis in Tregs as one of the critical pathways for the preferential accumulation of thymus-derived Tregs in the TME and suggest the axis as a potential therapeutic target for cancer immunotherapy.

Project description:The role of IL-33 and its receptor ST2 in kidney injury is not well understood. This study demonstrates the importance of ST2 expression on the T-regulatory cells (Tregs) for the resolution of renal injury by suppressing inflammation and fibrosis. Treg-specific deletion of ST2, detrimentally impacted late outcomes of renal injury worsening the impairment of kidney function, inflammation, and fibrosis.

Project description:Foxp3 expressing regulatory T cells (Tregs) are the central regulator of immune homeostasis and tolerance. As it is believed that proper Treg function is compromised under inflammatory conditions, exploring a pathway that enhances Treg function is of great importance. In this study, we report that IL-27, an IL-12 family cytokine known to play both pro- and anti-inflammatory role in T cells, plays a pivotal role in Treg function to control T cell-induced colitis. Unlike WT Tregs capable of inhibiting colitogenic T cell expansion and inflammatory cytokine expression, IL-27R-deficient Tregs were unable to downregulate inflammatory T cell responses. Tregs stimulated with IL-27 expressed substantially enhanced suppressive function both in vitro and in vivo. IL-27 stimulation of Tregs induced expression of LAG3, a surface molecule implicated in negatively regulating immune responses. LAG3 expression in IL-27-stimulated Tregs was critical to mediate suppressive Treg function. Finally, human Tregs also displayed enhanced suppressive function and LAG3 expression in response to IL-27 stimulation. Taken together, our results highlight a novel function of the IL-27/LAG3 axis in Treg regulation of inflammatory responses in the intestine. FACS purified Foxp3+ Tregs were stimulated in the presence of media or IL-27 to compare IL-27 induced gene profiles. Four samples (media stimulated or IL-27-stimulated) were collected from four independent experiments. Genes altered by IL-27 treatment were compared to those of media stimulated Tregs.

Project description:We describe the effects of Treg ST2 expression on muscle regeneration. We compare regneration from cryo-injured tibialis anterior muscle from Foxp3-Cre/ST2-flox vs Foxp3-Cre mice 8 days post-injury. These analyses from whole muscle provide insight into the role of muscle Tregs in the context of regeneration. The tibialis anterior muscle from male Foxp3-Cre/ST2 flox or Foxp3-Cre/ST2 WT C57BL/6 mice (2 months old) were cryo-injured using a liquid nitrogen chilled metal probe for 8 seconds. 8 days post-injury whole muscle was harvested and snap frozen in liquid nitrogen. Whole muscle was then homogenized directly in TriZol and gene expression profiling was performed on Affymetrix Mouse Gene 1.0 ST Arrays.

Project description:Recruitment of regulatory T cells (Tregs) to tumors is a hallmark of cancer progression. However, the role of epithelial cell-derived cytokines in regulation of Treg cells in colorectal cancers is not fully understood. We found a subset of Tregs co-expressing the receptors for thymic stromal lymphopoietin (TSLP) and IL-33 (TSLPR+ST2+ Tregs) was increased in colorectal tumors in humans and mice. This Treg subset expressed high levels of CTLA-4 and PD-1, and TSLPR signaling regulated the expression of CTLA-4 and number of TSLPR+ST2+ Tregs. Treg-specfic deletion of TSLPR resulted in a reduction in tumor number and size, with concomitant increase of Th1 cells in tumors. Similarly, blockade of TSLP effectively inhibited progression of colorectal tumors. On the other hand, TSLPR-ST2+ Tregs highly express Tgfb1 and Pdcd,1 which have been shown to suppress CD8+ T cell immune responses. Collectively, TSLP and IL-33 differentially regulate subsets of Tregs in the progression of colorectal tumor. These data suggest that TSLPR+ST2+ Treg cells are potentially a biomarker, and a therapeutic target for CRC.
