Project description:Many symptoms associated with allergic asthma result from the sequelae of type 2 inflammation. Interleukin (IL)-25 promotes type 2 inflammatory responses, and T2M cells represent an IL-4 and IL-13 producing granulocytic IL-25 responsive population. We used microarrays to characterize the gene expression profile of T2M cells, and compared T2M cells to other inflammatory subsets (eosinophils, neutrophils, and macrophages) in the lungs of mice with IL-25-induced pulmonary inflammation.

Project description:Eosinophils possess distinct functions, being pro-inflammatory in asthma and worm infection on the one hand, while supporting resolution of inflammation and tissue repair on the other hand. We could demonstrate that the immunological pathways causing asthma in the lungs at the same time elicit resolution of arthritis in the joints in an eosinophil-dependent manner. It can be hypothesized that the pro-inflammatory action of eosinophils in the lungs and their homeostatic functions in the synovium are mediated by tissue-specific functional priming. Therefore, single cell RNA sequencing (scRNA-seq) was used to investigate whether distinct eosinophil subsets arise in the lungs and the joints of mice upon combined asthma/arthritis model.

Project description:Aeroallergen sensing by airway epithelial cells can trigger pathogenic immune responses leading to chronic type 2 inflammation, the hallmark of airway diseases such as asthma. Airway tuft cells are specialized chemosensory epithelial cells and the dominant source of the epithelial cytokine IL-25 in the trachea and of cysteinyl leukotrienes (CysLTs) in the naïve murine nasal mucosa. How IL-25 and CysLTs might cooperatively promote type 2 inflammation in the airways has not been clarified. Here, we showed that inhalation of LTC4 in combination with a subthreshold dose of IL-25 led to dramatic synergistic induction of type 2 inflammation throughout the lungs, causing rapid eosinophilia, inflammatory type 2 innate lymphoid cell (ILC2) proliferation and type 2 cytokine production, dendritic cell (DC) and CD4+ T cell recruitment and goblet cell hyperplasia. While lung eosinophilia was dominantly mediated through the classical CysLT receptor CysLT1R, type 2 cytokines and activation of innate immune cells required signaling through both CysLT1R and CysLT2R. Tuft cell-specific deletion of Ltc4s, the terminal enzyme required for CysLT production, reduced lung inflammation and the systemic immune response after inhalation of the mold aeroallergen Alternaria; this effect was further enhanced by concomitant blockade of IL-25. Our findings identified a potent synergy of CysLTs and IL-25 downstream of aeroallergen-trigged activation of airway tuft cells leading to a highly polarized type 2 immune response and further implicate airway tuft cells as powerful modulators of type 2 immunity in the lungs.

Project description:Humans vary markedly in their propensity to develop asthma, despite often being exposed to similar environmental stimuli. Similarly, mouse strains vary in susceptibility to airways pathology in experimental asthma. Sensitization and aerosol challenge with ovalbumin (OVA) induces eosinophil accumulation, mucus production and airways obstruction in BALB/c and C57BL/6 mice. In contrast, CBA/Ca mice show relatively little pathology. Allergen-induced production of IL-4, IL-5, IL-10 and IFN-g was detected in all three strains, with BALB/c mice generating the highest levels of IL-4, IL-5 and IL-10. Microarray analysis was used to identify genes differentially regulated in lung tissue after OVA challenge. Differentially regulated genes in the lungs of the asthma-susceptible C57BL/6 and BALB/c strains numbered 242 and 145, respectively, whereas only 42 genes were differentially expressed in the resistant CBA/Ca strain. In C57BL/6 mice, transcripts were enriched for adhesion molecules and this was associated with high levels of eosinophil recruitment. Differentially regulated genes in the lungs of only the asthma-susceptible strains numbered 64 and several of these have not previously been associated with asthma. Many of the genes differentially regulated in the susceptible strains were enzymes involved in inflammation. Using network analysis, mRNA for the anti-apoptotic protein survivin was found to be up-regulated in the lungs following allergen challenge. Survivin mRNA and protein were also expressed at high levels in eosinophils recovered by bronchoalveolar lavage from BALB/c and C57BL/6 mice. We propose that rapid apoptosis of lung eosinophils due to low expression of survivin contributes to the limitation of pathology in CBA/Ca mice Humans vary markedly in their propensity to develop asthma, despite often being exposed to similar environmental stimuli.

Project description:IL-4-mediated pro-inflammatory vascular responses have been implicated in the pathogenesis of chronic cardiopulmonary diseases. Our results show that hypoxia-induced collagen synthesis and early recruitment of inflammatory cells are significantly less in the lungs of IL-4 knockout (KO) mice than in those of wild-type mice. In addition, we found that IL-4 significantly increased pro-inflammatory genes in primary pulmonary microvascular endothelial cells. This study was designed to identify the gene expression profile of IL-4-dependent pulmonary vascular inflammation induced by hypoxia.

Project description:Memory helper T cells provide long-lasting host defeMemory helper T cells provide long-lasting host defense against microbial pathogens, while distinct subpopulations of memory T cells drive chronic inflammatory diseases such as asthma. Asthma is a chronic allergic inflammatory disease with airway remodeling including fibrotic changes. The immunological mechanisms that induce airway fibrotic changes in allergic inflammation remain unknown. We found that Interleukin-33 (IL-33) enhanced Amphiregulin production by the IL-33 receptor, ST2hi memory T helper-2 (Th2) cells. Amphiregulin-epidermal growth factor receptor (EGFR)-mediated signaling directly reprogramed eosinophils to an inflammatory state with enhanced production of Osteopontin, a key profibrotic immunomodulatory protein. IL-5-producing memory Th2 cells and Amphiregulin-producing memory Th2 cells appeared to cooperate to establish lung fibrosis. The analysis of polyps from patients with eosinophilic chronic rhinosinusitis revealed fibrosis with accumulation of Amphiregulin-producing CRTH2hiCD161hiCD45RO+CD4+ Th2 cells and Osteopontin-producing eosinophils. Thus, the IL-33-Amphiregulin-Osteopontin axis directs fibrotic responses in eosinophilic airway inflammation and is a potential target for the treatment of fibrosis induced by chronic allergic disorders. against microbial pathogens, while distinct subpopulations of memory T cells drive chronic inflammatory diseases such as asthma.

Project description:Innate immune responses must be regulated in the intestine to prevent excessive inflammation. Here, using gene reporter mice, we show that a subset of mouse colonic macrophages constitutively produced the anti-inflammatory cytokine IL-10. In mice infected with Citrobacter rodentium, which is considered similar to enteropathogenic Escherichia coli infection in humans, macrophage IL-10 was required to prevent intestinal pathology and to promote survival. The synthesis of the proinflammatory cytokine IL-23 was significantly increased in infected mice with a myeloid cell specific deletion of IL-10 and the addition of IL-10 reduced in vitro IL-23 production by intestinal macrophages. Furthermore, blockade of IL-23 led to reduced morbidity and mortality in the context of macrophage IL-10 deficiency. Transcriptome analysis indicated that the reporter positive and negative colonic macrophage subsets were highly similar, but the reporter positive cells differed for the expression of CD163, an IL-10 target gene, suggesting an autocrine IL-10 signal, and when obtained from infected mice, they had reduced IL-23p19 mRNA. Interestingly, only transfer of the reporter positive cells could rescue IL-10 deficient infected mice. Therefore, these data indicate a pivotal role for a subset of intestinal macrophages that constitutively produces IL-10, perhaps acting in part in autocrine fashion, in controlling excessive innate immune activation, regulation of IL-23 production, and prevention of tissue damage after an acute bacterial infection in the intestine. Two replicates each of IL10+ and IL10- large intestinal macrophages. Data were normalized with the 'rma' function of the Bioconductor package, along with several GEO (GSM616132, GSM616136, GSM616140, GSM868296, GSM868297, GSM868298) and ArrayExpress (E-MEXP-3216: 04-M2WT, 05-M2WT, 06-M2WT) datasets.

Project description:Triggering Receptor Expressed on Myeloid cells 1 (TREM-1) an innate receptor that canonically amplifies inflammatory signaling in neutrophils and monocytes, plays a central role in regulating lung inflammation. Utilizing a murine model of asthma, flow cytometry revealed TREM-1+ eosinophils in the lung tissue and airway during allergic airway inflammation. TREM-1 expression was restricted to recruited, inflammatory eosinophils. Expression was induced on bone marrow derived eosinophils by incubation with IL-33, LPS, or GM-CSF. Compared to TREM-1- airway eosinophils, TREM-1+ eosinophils were enriched for pro-inflammatory gene sets including migration, respiratory burst, and cytokine production. Unexpectedly, eosinophil-specific ablation of TREM-1 increased airway IL-5 and lung tissue eosinophil accumulation. Further investigation of transcriptional data revealed apoptosis related gene sets were enriched in TREM-1+ eosinophils. Annexin V staining demonstrated higher rates of apoptosis among TREM-1+ eosinophils compared to TREM-1- eosinophils in the inflammatory airway. In vitro, Trem1/3-/- eosinophils were protected from apoptosis. Finally, inhibition of reactive oxygen species production with diphenyleneiodonium protected WT bone marrow derived eosinophils from apoptosis more than Trem1/3-/- eosinophils, suggesting that superoxide accounted for more apoptosis in WT cells. These data demonstrate protein level expression of TREM-1 by eosinophils for the first time, define a population of TREM-1+ inflammatory eosinophils, and reveal that eosinophil TREM-1 restricts key features of type 2 lung inflammation.
