Cysteine protease exposure induces upper airway rhinosinusitis through IL-33 mediated effects on innate immune and epithelial barrier function

ABSTRACT: A hallmark of type 2 inflammation in rhinosinusitis is the presence of eosinophilic infiltrates. In the lung, the cysteine protease papain causes robust type 2 inflammation due to innate mucosal immunity triggered by interleukin-33 release from the epithelial lining. As these effects are poorly understood for the sinonasal tissues, we investigated the epithelial and inflammatory findings induced by short-term papain instillation in the upper airway. C57BL/6 mice were intranasally exposed to papain and PBS as a model for protease-induced epithelial injury inflammation. We assessed the upper airway for changes mRNA shifts by microarray.

Microarray analysis of epithelial and fibroblast cells in chronic rhinosinusitis

Project description:Chronic rhinosinusitis without polyps (CRSsNP) is typified by inflammation of the sinonasal epithelium and the development of fibrosis. The precise pathophysiology of this common condition remains elusive. Here we aim to investigate the transcriptome (RNA transcripts in the cell) of the component nasal epithelial and fibroblast cells in CRSsNP and health to identify if there are clusters of differentially expressed genes as possible novel CRS therapeutic targets. Gene expression profiling by Illumina BeadArray of primary nasal epithelial and fibroblast cells in heatlh and chronic sinusitis. Samples from consenting human donors (Epithelial Case, n=13, Epithelial Control, n=11, Fibroblast Case, n=12, Fibroblast Control, n=12).

STAT6 Blockade Abrogates Aspergillus-Induced Eosinophilic Chronic Rhinosinusitis and Asthma, a Model of Unified Airway Disease

Project description:Unified airway disease, including concurrent asthma and chronic rhinosinusitis (CRS), is a common, but poorly understood disorder with no curative treatment options. To establish a murine model of chronic unified eosinophilic airway inflammation, mice were challenged with Aspergillus niger, and sinonasal mucosa and lung tissue were evaluated by immunohistochemistry, flow cytometry and gene expression. Inhalation of A niger conidia resulted in a Th2-biased lung and sinus inflammation that typifies allergic asthma and CRS. Gene network and pathway analysis correlated with human disease with upregulation of the JAK-STAT and helper T cell pathways, but also less expected pathways governing the spliceosome, osteoclast differentiation, and coagulation pathways. Utilizing a specific inhibitor and gene-deficient mice, we demonstrate that STAT6 is required for mycosis induced sinus inflammation. These findings confirm the relevance of this new model and portend future studies that further extend our understanding of the immunopathologic basis of airway mycosis and unified airway disease.

CC10 gene deletion: Effect on gene expression in the sinonasal mucosa

Project description:Comparative analysis of gene expression in murine sinonasal mucosa in wild-type and CC10-knockout littermates with allergic eosinophilic chronic rhinosinusitis. The data provide a comprehensive overview of genes expressed in the mouse sinonasal mucosa and show that the expression of several known and unidentified genes is modified by disruption of the CC10 gene. Total RNA isolated from sinonasal mucosae of 6- to 8-week-old mice, C57BL/6 strain, was used for this comparison. Three groups: wild-type control, wild-type with allergic eosinophilic chronic rhinosinusitis, and CC10-knockout with allergic eosinophilic chronic rhinosinusitis.

S100A8 Enhances IL-1β Production from Nasal Epithelial Cells in Eosinophilic Chronic Rhinosinusitis

Project description:Chronic rhinosinusitis is classified into eosinophilic chronic rhinosinusitis (ECRS) and non-eosinophilic chronic rhinosinusitis (NECRS). ECRS is a refractory allergic disease involving a variety of immune and epithelial cells. S100A8 is a damage-associated molecular pattern that is closely related to allergic inflammation. However, the pathological implications of S100A8 in ECRS have not been clarified. We evaluated the role of S100A8 in the pathogenesis of ECRS. Gene expression profiles of nasal polyps obtained from patients with ECRS or NECRS were evaluated using RNA sequencing. S100A8 was identified as a significantly upregulated gene in nasal polyps associated with ECRS. Consistently, immunohistochemistry revealed that S100A8 stained intensely in nasal polyps from patients with ECRS. Human nasal epithelial cells expressed the receptor for advanced glycation end products and Toll-like receptor 4. Recombinant S100A8 protein induced interleukin-1β secretion in human nasal epithelial cells. Our data demonstrate that S100A8 induces production of interleukin-1β in the nasal epithelium, which may be involved in the pathogenesis of ECRS.

RNAseq analysis for lung resident cells from protease allergen and FK506 treated mice

Project description:There is evidence for the beneficial effect of FK506, an effective immunosuppressive agent, for the treatment of asthma; however, the mechanisms underlying these effects are unclear. Using a mouse model of airway inflammation induced by Papain, a protease allergen, and RNAseq analysis of lung innate cells, we found that FK506 inhibited the activation of ILC2s, which initiate airway inflammation, as well as the induction of TH2 cells, which cause chronic inflammation. Our findings further support the clinical value of FK506 for the treatment of allergen-induced airway inflammation and clarify its targets and mechanisms of action.

Upper airway gene expression is an effective surrogate biomarker for Th2-driven inflammation in the lower airway

Project description:Molecular profiling studies in asthma cohorts have identified a Th2-driven asthma subtype, characterized by elevated lower airway expression of POSTN, CLCA1 and SERPINB2. To assess upper airway gene expression as a potential biomarker for lower airway Th2 inflammation, we assayed upper airway (nasal) and lower airway (bronchial) epithelial gene expression, serum total IgE, blood eosinophils and serum periostin in a cohort of 54 allergic asthmatics and 30 matched healthy controls. 23 of 51 asthmatics in our cohort were classified as âTh2 highâ based on lower airway Th2 gene signature expression. Consistent with this classification, âTh2 highâ subjects displayed elevated total IgE and blood eosinophil levels relative to âTh2 lowâ subjects. Upper airway Th2 signature expression was significantly correlated with lower airway Th2 signature expression (r=0.44), with similar strength of association as serum total IgE and blood eosinophils, known biomarkers of Th2 inflammation. In an unbiased genome-wide scan, we identified 8 upper airway genes more strongly correlated with lower airway Th2 gene signature expression (r=0.58), including Eotaxin-3 (CCL26), Galectin-10 (CLC) and Cathepsin-C (CTSC). Asthmatics classified as âTh2 highâ using this 8-gene signature show similar serum total IgE and blood eosinophil levels as âTh2 highâ asthmatics classified using lower airway Th2 gene signature expression. We have identified an 8-gene upper airway signature correlated with lower airway Th2 inflammation, which may be used as a diagnostic biomarker for Th2-driven asthma. Upper airway (nasal) and lower airway (bronchial) epithelial brushings obtained from a cohort of 54 allergic asthmatics and 30 matched healthy controls were profiled by gene expression by microarray. Subjects were assayed for gene expression, serum total IgE, blood eosinophils and serum periostin.

Gene expression analysis of Chronic rhinosinusitis

Project description:Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by local inflammation of the upper airways which persists for at least 12 weeks. CRS is one of the most common chronic diseases in adults in the United States, affecting over 30 million Americans. CRS is frequently divided into 2 types: CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Histologic studies have demonstrated significant tissue eosinophilia in CRSwNP. T cells in the mucosa are elevated in both forms of CRS and are skewed towards Th2 cytokine expression in CRSwNP. However pathogenic role of CRS has not been fully explored. To screen for pathogenic factors in CRS, we performed a microarray study. We collected uncinate tissues (UT) from 6 subjects with CRSsNP, 6 subjects with CRSwNP and 6 control subjects and nasal polyp (NP) tissues from 6 subjects with CRSwNP and then evaluated gene expression profiles using Affymetrix Human Genome U133 plus 2.0 array. We collected UT from control subjects and pathients with CRSsNP and CRSwNP, and nasal polyp tissues from patients with CRSwNP. Gene expression profiles were evaluated using Human Genome U133 plus 2.0 array (Affymetrix).
