(Submitter supplied) Airway macrophages (AMs) are the most abundant leukocytes in the healthy airway lumen and have a highly specialised but plastic phenotype that is governed by the local microenvironment. AMs are thought to maintain immunological homeostasis in the steady state, but have also been implicated in the pathogenesis of allergic airway disease (AAD). To better understand these potentially contrasting AM functions, bulk RNA sequencing was performed on murine AMs obtained during experimental AAD driven by repeated house dust mite inhalation (AM[HDM]s), comparing to control AMs from non-allergic mice. more...

(Submitter supplied) Preschool wheeze is an early life bronchoconstriction disorder with an increased risk of progression to chilhood asthma. Preschool wheeze is typically triggered by respiratory infection, but airway inflammatory phenotypes, including the phenotype of airway macrophages (AMs), in preschool wheeze is not fully understood. In this study, AMs were sorted from preschool wheeze patients and non-wheezing paediatric controls under clinical investigation for chronic cough and gene expression assessed by Illumina mRNA sequencing (110 base pair, paired end reads). more...

(Submitter supplied) We have identified CD25high and CD25low ILC2 subsets in various mouse models of airway inflammation. Transcriptome analysis of acute IL-33 (CD25High) or chronic HDM (CD25Low) activated murine lung ILC2s suggests functional differences between these two ILC2 populations.

(Submitter supplied) Mild asthmatics who met the criteria of the IRB approved protocol of Sub-segmental Bronchial Provocation with Allergen were recruited. The subjects were challenged with sensitive allergen through bronchoscopy. Bronchoalveolar lavage (BAL) fluids were collected before and at 48 hours after allergen challegen. From the BAL fluids, alveolar macrophages were purifed and their RNA was extracted. Total 138 genes including five house keeping genes were evaluated.

(Submitter supplied) Isthmin 1 (ISM1) is a secreted 60 kDa protein that exhibits pro-apoptotic and anti-angiogenic functions in experimental settings. We generated ISM1 knockout mice (ISM1-/- ) in C57BL/6J background through CRISPR gene editing technology to understand the physiological function of endogenous ISM1. The ISM1-/- mice presented spontaneous pulmonary emphysema and immune infiltration under the ambient environment. more...

(Submitter supplied) RATIONALE: The development and progression of asthma are strongly influenced by environmental exposures. We have demonstrated that mice exposed to a diet enriched with methyl donors during vulnerable periods of fetal development can enhance the heritable risk of allergic airway disease through epigenetic changes. OBJECTIVES: Since there is conflicting evidence on the role of folate in modifying allergic airway disease risk, we hypothesized that blocking folate metabolism through the loss of methylene-tetrahydrofolate reductase (MTHFR) activity would reduce the allergic airway disease phenotype. more...

(Submitter supplied) 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. more...

(Submitter supplied) Purpose: To elucidate the effects of SCD1 inhibitor in allergic airway inflammation. Method: Wild-type mice were sensitized intratracheally twice with house dust mite (HDM) extract at a 7-day interval. Along with that, an SCD-1 inhibitor, A939572 was also administered intraperitoneally daily. 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, 385 transcripts showed differential expression between SCD1 inhibitor-treated mice and DMSO (vehicle)-treated mice with adjusted p value <0.05.

(Submitter supplied) The very low density lipoprotein receptor (VLDLR) is a multi-ligand receptor that mediates pleiotropic biological processes, such as brain development. In this dataset, we include the expression data obtained from lungs from mice that had been challenged with house dust mite to induce experimental asthma or saline, as a control. These data are used to obtain genes that are differentially expressed in response to VLDLR signaling.
