IgE antibodies mediate the symptoms of allergic reactions, yet these antibodies and the cells that produce them remain enigmatic due to their scarcity in humans. To address this, we have isolated single B cells of all isotypes, including rare IgE producing B cells, from the peripheral blood of food allergic individuals. Using single cell RNA sequencing (scRNA-seq) we have characterized the gene expression, splicing, and heavy and light chain antibody sequences of these cells.

View SamplesTumor 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. Overall design: 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
