Lung biopsies from sensitized or control rhesus macaques

ABSTRACT: The aim of this study was to investigate differential expression in a house dust mite (HDM) exposure model of asthma in rhesus macaques. HDM sensitization was performed by subcutaneous injection of HDM followed by intranasal HDM for 2-3 hours twice a week.

Lung biopsies from sensitized or control rhesus macaques

Project description:The aim of this study was to investigate differential expression in a house dust mite (HDM) exposure model of asthma in rhesus macaques. HDM sensitization was performed by subcutaneous injection of HDM followed by intranasal HDM for 2-3 hours twice a week. Animals were mock-sensitized (PBS) or sensitized to HDM antigen. Gene expression was measured in lung biopsies before and fifteen weeks after treatment.

Expression data from lung CD11b+ conventional dendritic cells in the steady-state and following exposure to house dust mite allergens

Project description:Using mouse lung resident conventional CD11b+ dendritic cells (CD11b+ cDCs) in the context of house-dust mite (HDM)-driven allergic airway sensitization as a model, we aimed here to identify transcriptional events regulating the pro-Th2 activity of cDCs. We used microarray analyses to identify genes differentially expressed by lung CD11b+ conventional dendritic cells in response to house dust mite allergens in wild-type and Irf3-deficient mice

Transcriptomic analysis in airway epithelial cells in HDM-sensitized STAT3-WT and STAT3-cKO mice

Project description:Purpose: To elucidate the roles of airway epithelial STAT3 in allergic airway inflammation. Method: Doxycycline-induced airway epithelial cells-specific STAT3-deficient mice (STAT3-cKO) and their genetic control mice (STAT3-WT) were sensitized intratracheally twice with house dust mite (HDM) extract or PBS at a 7-day interval. Airway epithelial cells were isolated by a cell sorter 48 h after the last senstization. N=2 each. Results: Using an optimized data analysis workflow, 206 transcripts showed differential expression between HDM-treated STAT3-WT and STAT3-cKO with adjusted p value <0.05.

ORAI1 is required for T cell mediated allergic airway inflammation but not antiviral immunity in the lung

Project description:This study investigates the role of store-operated calcium entry (SOCE) in T cell-mediated immune responses to pulmonary influenza A virus (IAV) infection and allergic airway inflammation after immunization by house dust mite (HDM) allergens. We conducted a comparative gene expression analysis of antigen-specific CD4+ T cells from wildtype (WT) and Orai1fl/fl Cd4Cre mice that were adoptively transferred to TCRalpha knockout mice followed by sensitization / challenge with HDM or infection with influenza A virus (IAV) strain x31. Donor CD4+ T cells were isolated from the lungs of host mice at days 9 (IAV) and 14 (HDM), RNA was isolated and processed for bulk RNA sequencing.

Gene expression patterns in house dust mite stimulated CD4 T cells and IgG:IgE ratios

Project description:PBMC from house dust mite (HDM) sensitized atopics were cultured in the presence or absence of HDM extract for 24 hours. At the termination of the cultures, CD4 T cells were isolated using immunomagnetic separation. Gene expression was profiled on microarrays. The study design consisted of 45 subjects and two conditions (medium control, HDM stimulation).

Transcriptional changes in mouse lungs induced by house dust mite

Project description:We examined the transcriptional changes in mouse lungs induced by house dust mite (HDM), D.f. extract and the isolated RNA was utilized for RNA-seq analysis. Our results demonstrated that HDM strongly triggered an inflammatory response.

Alteration in gene expression in the lung following neonatal RSV infection

Project description:mRNA expression data from BALB/c mice which were infected intranasally with Respiratory Syncytial Virus (or Hep-2 cell lysate control) at 1 week old and challenged with PBS or house dust mite (HDM) extract as adults. Experimental groups: RH – neonatal RSV, adult HDM, RP – neonatal RSV, adult PBS, HH – neonatal Hep-2, adult HDM and HP – neonatal Hep-2, adult PBS.

RNA-Seq analysis of BEAS-2b cells stimulated with house dust mite extract with or without suppression of MD-2

Project description:We clarified MD-2 might have a protective role in house dust mite(HDM)-induced asthmatic characteristics. The purpose of RNA-Seq analysis is to identify transcriptional events regulated by MD-2 in HDM-stimulated airway epithelial cells.

Gene expression patterns in allergen-driven CD4 T cell responses from human atopics with or without asthma.

Project description:PBMC from house dust mite (HDM) sensitized atopics with or without asthma (or nonallergic controls) were cultured in the presence or absence of HDM extract for 24 hours. At the termination of the cultures, immunomagnetic separation was performed to purify CD4 T cells. Gene expression was profiled on microarrays. The study design consisted of 72 subjects, and two experimental conditions (medium control, HDM stimulation).
