Single cell profiling of cerebral immune cells in the Interleukin-33 (IL-33) driven tumor microenvironment

Project description:IL33 is a dual function cytokine which acts as a major orchestrator of the brain tumor microenvironment that contributes to tumorigenesis. We found that IL33 is expressed in a large subset of human glioma patient specimens and murine glioma models and that its expression is directly associated with the increased presence of tumor associated macrophages/monocytes/microglia. We analyzed the differences in the IL-33+ and IL-33- innate immune microenvironments at a single cell resolution and found substantial differences in the immune populations present and gene expression changes which may contribute to the increased tumoirgenicity of IL-33+ tumors.

A proteomic landscape of the spatiotemporal influence of Interleukin-33 (IL-33) in monocytes

Project description:Interleukin-33 (IL-33), a member of the IL-1 superfamily cytokines, is an endogenous danger signal and a nuclear-associated cytokine. It is one of the essential mediators of both innate and adaptive immune responses. Aberrant IL-33 signaling has been demonstrated to play a defensive role against various infectious and inflammatory diseases. Although the signaling responses mediated by IL-33 have been previously reported, the temporal signalingdynamicsare yet to be explored. Towards this end,we applied quantitative temporal phosphoproteomics analysis to elucidate pathways and proteins induced by IL-33 in THP1 monocytes. Employing TMT labeling-based quantitation and titanium dioxide (TiO2)-based phosphopeptide enrichment strategy followed by mass spectrometry analysis, we identified 14,515 phosphorylation sites mapping to 4,174 proteins across (0 min to 240 mins)time points.

Dataset of spatiotemporal influences of interleukin IL-1 family cytokine: Interleukin-33 on cellular signal transduction pathways

Project description:Interleukin-33 (IL-33) is a member of the IL-1 family of cytokines that play a central role in the regulation of immune responses. IL-33 signaling, from the early signaling events triggered by the ligand-activated receptor to result in activation of early and late signaling events, such as proteome changes. In this study, THP1 (monocyte) cell line model was stimulated with IL-33 (50 ng/ml) for varying duration (5, 10, 15, 30, 40, 60, 120 and 240 mins). We carried out in-depth proteomic analysis using high-resolution LC-MS/MS. Our analysis resulted in the identification of 64,030 peptides corresponding to 7947 protein groups. Differentially regulated proteins identified in this study could be targeted for developing an inflammatory immune response.

Glioma cells response Interleukin-33 (IL-33) [microarray]

Project description:Determination of the molecular mechanism of IL33 on glioma cells Since IL-33 is known to associate with chromatin and regulate transcriptional activity and that nuclear expression of IL-33 increases glioma progression, we determined Nuclear IL-33 regulates the expression and secretion of inflammatory cytokines in glioma cells. Using these parameters 340 genes were induced by the ectopic expression of IL-33 and an additional 377 genes were downregulated. Gene ontology terms over-represented in the genes induced by IL-33 include three major clusters that associate with cytokine activity and inflammation

IL-33 activates tumor stroma to promote intestinal polyposis

Project description:Tumor epithelial cells develop within a microenvironment consisting of extracellular matrix, growth factors, and cytokines produced by non-epithelial stromal cells. In response to paracrine signals from tumor epithelia, stromal cells modify the microenvironment to promote tumor growth and metastasis. Here, we identify interleukin (IL)-33 as an epithelial cell-derived regulator of stromal cell activation and mediator of intestinal polyposis. IL-33 expression was elevated in the tumors and serum of colorectal cancer patients and induced in the adenomatous polyps of ApcMin/+ mutant mice. Genetic and antibody suppression of IL-33 signaling in ApcMin/+ mice inhibited proliferation, induced apoptosis, and suppressed angiogenesis in polyps, which reduced both tumor number and size. In ApcMin/+ polyps, IL-33 expression localized to tumor epithelial cells and expression of the IL-33 receptor, IL1RL1, associated with two stromal cell types, namely subepithelial myofibroblasts (SEMFs) and mast cells, whose activation was previously associated with polyposis. In vitro IL-33 stimulation of human SEMFs induced the expression of extracellular matrix components and growth factors associated with intestinal tumor progression. IL-33 deficiency reduced mast cell accumulation in ApcMin/+ polyps and expression of mast cell-derived proteases and cytokines known to promote polyposis. Together, our results suggest that IL-33 is a tumor epithelial cell-derived paracrine signal that promotes polyposis through the coordinated activation of stromal cells and the formation of a reactive stroma microenvironment. Six T-75 flasks of CCD-18Co cells were grown to 80% confluency; three were treated with rhIL-33, three were given vehicle control; cells were trypsinized and split in two--half of each flask used for sequencing and half for qPCR validation post-sequencing

Glioma-derived IL-33 orchestrates an inflammatory brain tumor microenvironment that accelerates glioma progression

Project description:In order to further understand how glioma-derived IL-33 is orchestrating changes within the tumor microenvironment and based on the significant increase of anti-inflammatory mediators including a number of signaling molecules observed in IL-33+ tumors, we performed phospho-proteomic analysis using mass spectrometry on the brains of tumor-bearing mice.
