RNA-seq profile of expanded human ST2-transduced Tregs cultured with IL-2 and TCR in the presence or absence of IL-33

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.

Transcriptional profiling of mouse ST2+ and ST2- Tregs across tissues

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.

The impact of IL-33 on Srebf2-dependent cholesterol gene expression in ST2+ eVAT Tregs

Project description:Tregs are highly enriched in the eVAT of male mice. We show that ST2+ VAT Tregs preferentially upregulate and depend on Srebf2-mediated cholesterol metabolism compared their spleen Treg or ST2- VAT Treg counterparts. However, it is unclear whether this increased reliance on cholesterol metabolism is a consequence elevated IL-33 signaling in ST2+ Tregs. Therefore, the goal of experiment is to determine whether IL-33 signaling influences Srebf2-dependent cholesterol gene expression in ST2+ eVAT Tregs in vivo.

RNA-Sequencing of ST2+ Treg cells in response to IL-33 stimulation

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.

RNA-seq of ST2+ and ST2- Tregs in the omentum from naïve and tumor-bearing mice

Pairwise comparison of ST2+ and ST2- FOXP3+ T cells derived from mouse intestinal tumors

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.

Tumor-Infiltrating Regulatory T Cell Accumulation in the Tumor Microenvironment is Mediated by IL33/ST2 Signaling

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.

ST2+ T-regulatory Cells in Renal Inflammation and Fibrosis following Ischemic Kidney Injury

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.
