Expression data from bronchial epithelial cell obtained before and after bronchial thermoplasty treatment in severe asthma

ABSTRACT: Biological mechanisms explaining asthma control improvement following bronchial thermoplasty are still not well understood. We used a large-scale transcriptomic approach to evaluate the transcriptome of bronchial epithelial cell (BEC) obtained before and after bronchial thermoplasty treatment (BT).

Gene signature profiles in bronchial tissues from severe asthma patients treated with bronchial thermoplasty

Project description:Bronchial thermoplasty (BT) is an endoscopic therapy employed for the treatment of refractory asthma. However, no predictive factors are available that determine the effectiveness of BT in treating asthma patients. The present study aimed to comprehensively analyze RNA samples from the airway bronchial tissues of 8 patients with severe asthma treated by BT, and to characterize each patient as a BT responder or non-responder. Total 24 RNA samples (three per patient prior to BT1 [baseline], prior to BT2 [after 1st time treatment], and prior to BT3 [after 2nd time treatment]) were obtained. There were 975 differentially expressed (DE) genes in the bronchial tissues of 8 patients between prior to BT1 (baseline) and prior to BT2 (after 1st time treatment), with significant differences (FDR-adjusted P<0.05). Subjects with an Asthma Quality of Life Questionnaire score change of >0.5 for a period of 12 months were considered BT responders. Non-responders exhibited a score change of <0.5 for 12 months. Transcriptome analysis at baseline identified 67 genes that were differentially expressed between responders and non-responders, including SLPI, MMP3, and MUC19 which were upregulated in responders.

Comparison of bronchial epithelial cells obtained by bronchoscopy from severe asthma patients before and after thermoplasty treatment

Project description:In this study we explore the underlying differences in bronchial epithelial cells from severe asthma patients obtained before and after thermlasty treatment. The effect of the treatment on bronchial epithelial cells will be revealed based on the genes differentialy expressed post treatment.

Comparison of bronchial epithelial cells obtained by bronchoscopy from mild asthma patients, moderate asthma patients, severe asthma patients and healthy controls

Project description:In this study we explore the underlying differences in bronchial epithelial cells from asthma patinets compared to healthy controls. In addition we also explore the differential gene expression of severe asthma patients compared to mild and moderate asthma patients to determine if there are genes that lead to severity of the disease

Severe asthmatic bronchial smooth muscle decreases epithelial response to rhinovirus infection.

Project description:Asthma is a very frequent airway disease that affects 6 to 20% of the population. Severe asthma, represents 3 to 5% of all asthmatic patients and is histologically characterized by an increased bronchial smooth muscle (BSM) mass and clinically by viral exacerbations. Functionally, BSM remodeling had a poor prognostic value in asthma, since higher BSM mass was associated with lower lung function and increased exacerbation rate. However, the role of BSM as a potential actor of asthma exacerbation has only been sparsely suggested. We thus hypothesis that asthmatic BSM cells could act on bronchial epithelium and modified its response to rhinovirus infection.

Segmental Bronchial Allergen Challenge Elicits Distinct Metabolic Phenotypes in Allergic Asthma

Project description:Asthma is a complex syndrome associated with episodic decompensations provoked by aeroaller-gen exposures. The underlying pathophysiological states driving exacerbations are latent in the resting state and do not adequately inform biomarker-driven therapy. A better understanding of the pathophysiological pathways driving allergic exacerbations is needed. We hypothesized that disease-associated pathways could be identified in humans by unbiased metabolomics of bron-choalveolar fluid (BALF) during the peak inflammatory response provoked by a bronchial aller-gen challenge. We analyzed BALF metabolites in samples from 12 volunteers who underwent segmental bronchial antigen provocation (SBP-Ag). Metabolites were quantified using liquid chromatography-tandem mass spectrometry (LC–MS/MS) followed by pathway analysis and cor-relation with airway inflammation. SBP-Ag induced statistically significant changes in 549 fea-tures that mapped to 72 uniquely identified metabolites. From these features, two distinct induci-ble metabolic phenotypes were identified by the principal component analysis, partitioning around medoids (PAM) and k-means clustering. Ten index metabolites were identified that in-formed the presence of asthma-relevant pathways, including unsaturated fatty acid produc-tion/metabolism, mitochondrial beta oxidation of unsaturated fatty acid, and bile acid metabolism. Pathways were validated using proteomics in eosinophils. A segmental bronchial allergen chal-lenge induces distinct metabolic responses in humans, providing insight into pathogenic and pro-tective endotypes in allergic asthma.
