IL-33-ST2 axis regulates myeloid cell differentiation and activation enabling effective club cell regeneration.

Project description:Evidence points to an indispensable function of macrophages in tissue regeneration, yet the underlying molecular mechanisms remain elusive. Here we demonstrate a protective function for the IL-33-ST2 axis in bronchial epithelial repair, and implicate ST2 in myeloid cell differentiation. ST2 deficiency in mice leads to reduced lung myeloid cell infiltration, abnormal alternatively activated macrophage (AAM) function, and impaired epithelial repair post naphthalene-induced injury. Reconstitution of wild type (WT) AAMs to ST2-deficient mice completely restores bronchial re-epithelialization. Central to this mechanism is the direct effect of IL-33-ST2 signaling on monocyte/macrophage differentiation, self-renewal and repairing ability, as evidenced by the downregulation of key pathways regulating myeloid cell cycle, maturation and regenerative function of the epithelial niche in ST2-/- mice. Thus, the IL-33-ST2 axis controls epithelial niche regeneration by activating a large multi-cellular circuit, including monocyte differentiation into competent repairing AAMs, as well as group-2 innate lymphoid cell (ILC2)-mediated AAM activation.

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.

Charaterization of function of ST2 receptor on macrophages function during Club cell regeneration after naphthalene injury in WT mice

Project description:During repair phase after naphathalene injury 3 subsets of myeloid cells accumulate at the site of injury including P1 (monoyte), P2 (monocyte-derived macrophages and P3 (resident alternatively activated airway macrophages). ST2 receptor was found to be expressed by P2 and P3 subsets. To understand which biological processes in lung macrophages were regulated by ST2, myeloid cell subsets were flow-sorted from Naphthalene-treated WT and ST2-/- mice on d6 and their transcriptome analyzed using RNA-seq

Bronchiolar progenitors and club cells in mouse lung

Project description:Gene expression patterns of bronchiolar progenitors and club cells in mouse lung were examined by microarray experiments. Although it has not yet been fully characterized, a subset of epithelial cells lining bronchioles are best understood as bronchiolar progenitors that self-renew over the long term and that can differentiate into more differentiated club cells and ciliated cells. The bronchiolar progenitors are distinct from club cells and characteristically express the alveolar type 2 cell marker, prosurfactant protein C, with lower levels of club cell secretory protein/Scgb1a1. There are also functional differences between them; while club cells can be depleted by naphthalene because of the abundance of cytochrome P450 enzyme Cyp2f2, bronchiolar progenitors are resistant to naphthalene-induced depletion because of defects in the enzyme.

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.

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.

IL-33 and ST2 license beige and brown adipocytes for uncoupled respiration

Project description:For placental mammals, the transition from the in utero maternal environment to postnatal life requires the activation of thermogenesis to maintain their core temperature. This is primarily accomplished by induction of uncoupling protein 1 (UCP1) in brown and beige adipocytes, the principal sites for uncoupled respiration. Despite its importance, how placental mammals license their thermogenic adipocytes to participate in postnatal uncoupled respiration is not known. Here, we provide evidence that the 'alarmin' IL-33, a nuclear cytokine that activates type 2 immune responses, licenses brown and beige adipocytes for uncoupled respiration. We find that, in absence of IL-33 or ST2, beige and brown adipocytes develop normally but fail to express an appropriately spliced form of Ucp1 mRNA, resulting in absence of UCP1 protein, and impairment in uncoupled respiration and thermoregulation. Together, these data suggest that IL-33 and ST2 function as a developmental switch to license thermogenesis during the perinatal period.

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.
