The IL-33/ST2 axis and tissue Treg maintains epithelial homeostasis in the skin and restrains cancer development

Project description:IL-33 is constitutively expressed in many epithelial tissues at steady state and signals through the receptor, ST2. IL-33 is released upon tissue injury and functions as an endogenous danger signal to alert the immune system to tissue damage. Here we investigate the physiological role of the IL-33/ST2 axis in skin homeostasis and cancer development. We show that expression of IL-33 differentiates malignant from normal/benign human tissues and that in mouse models of cutaneous squamous cell carcinoma the IL-33/ST2 axis protects against carcinogenesis. Tissue Treg are the predominant cells expressing ST2 in the skin and localise around the hair follicle and IL-33+ epithelial cells (EC). Adoptive transfer experiments demonstrate that skin Treg regulate EC differentiation, minimizes mutational load and retrains cancer development following exposure to an environmental carcinogen. Our findings indicate an important role for direct EC-Treg cross-talk as an early checkpoint to contain tissue damage and carcinogenesis.

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.

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.

Bcl6 restrains ST2+ Treg cell development through negative regulation of Blimp1 in the context of allergic inflammation

Project description:Bcl6 play a key role in CD4+ T cell development including follicular regulatory T cells. However, the role of Bcl6 in Treg cells in context of allergic inflammation was not fully understood. In this study, we describe the role of Bcl6 in development and function of ST2+Treg cells by analyzing ST2+Treg cell RNA seq.

Irisin improves obesity and glucose intolerance through an IL-33-ST2 pathway

Project description:Irisin is secreted by muscle, increased with exercise, and conveys certain physiological benefits. Earlier studies showed that short-term irisin treatment caused browning of subcutaneous adipose tissue (SAT) in mice, with improved glucose tolerance; the effects of more chronic irisin treatment and mechanisms at play have not been explored. We demonstrate here that chronic irisin application improves obesity and dramatically reduces glucose intolerance. This treatment increases an IL-33+ mesenchymal stromal cell (mSC) population in visceral fat tissue while genetic ablation of irisin reduces plasma IL-33 levels and decreases thermogenic gene expression in SAT. Importantly, irisin directly induces IL-33 expression in mSCs and preserves ST2+ regulatory T (Treg) cells. Inhibition of IL-33 blunts these irisin-mediated effects on energy expenditure and glucose homeostasis, largely through IL33-mediated regulation of ST2+ Treg cells. These data indicate that irisin improves obesity and glucose intolerance, with no muscle loss, through a key immunomodulatory pathway in obese mice.

Differential roles of TSLP and IL-33 in regulation of Treg cells in progression of colorectal cancer

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.

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.

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.
