Project description:In a prior report, we observed two distinct lung microbiomes in healthy subjects that we termed â??pneumotypesâ??: pneumotypeSPT, characterized by high bacterial load and supraglottic predominant taxa (SPT) such as the anaerobes Prevotella and Veillonella; and pneumotypeBPT, with low bacterial burden and background predominant taxa (BPT) found in the saline lavage and bronchoscope. Here, we determined the prevalence of these two contrasting lung microbiome types, in a multi-center study of healthy subjects. We confirmed that a lower airway microbiome enriched with upper airway microbes (pneumotypeSPT) was present in ~45% of healthy individuals. Cross-sectional Multicenter cohort. BAL of 49 healthy subjects from three cohort had their lower airway microbiome assessed by 16S rDNA sequencing and microbial gene content (metagenome) was computationally inferred from taxonomic assignments. The amplicons from total 100 samples are barcoded; the barcode and other clinical characteristics (e.g. inflammatory biomarkers and metabolome data) for each sample are provided in the 'Pneumotype.sep.Map.A1.txt' file.

Project description:The goal of this study was to evaluate the biological effect of microplastic fibres on nasal epithelium from healthy subjects, as well as asthma and COPD pateients. We demonstrated the distinct biological response of asthmatic and COPD epithelial cells to microplastic fibers stimulation compared to healthy epithelial cells. ANKRD36, BCL2L15, C15orf48, CAPN14, FCGBP, FST, IL-19, MAFF, PGBD5, PKP1 and PTPRH are important markers of epithelial response after microplastic stimulation in obstructive lung disaeses. These mediators are linked to Th2 inflammation, alleviation of stress response, and, most notably, carcinogenesis.

These mediators are linked to Th2 inflammation, alleviation of stress response, and, most notably, carcinogenesis. Microplastic stimulation differently modified the response of airway epithelial cells in obstructive lung diseases than in controls. Asthmatic and COPD epithelial cells are more prone to damage after microplastic fibre exposure.

Project description:We investigated the effects on the lungs during fetal in the offspring of asthmatic mothers. Lung ILC2 of offspring of asthmatic mothers altered phenotypically during fetal life.

Project description:In this study, we assessed lower airway microbiome from a cohort of patients to determine whether specific microbiome taxa correlate with with specific metabolic activities. In a subset of 12 patients, transcriptomic expression were analyzed to compare host mucosa immune response We collected peripheral airway brushings from the 12 subjects whose lung microbiome were analyzed; Total RNA were obtained from the peripheral airway epithelium.
