(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is a highly prevalent respiratory disease characterized by airflow limitation and chronic inflammation. MiR-155 is described as an ancient regulator of the immune system. Our objective was to establish a role for miR-155 in cigarette smoke (CS)-induced inflammation and COPD. We demonstrate increased miR-155 expression by RT-qPCR in lung tissue of smokers without airflow limitation and patients with COPD compared to never smokers and in lung tissue and alveolar macrophages of CS-exposed mice compared to air-exposed mice. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD), the fourth leading cause of death globally, is influenced by both cigarette smoking and genetic determinants. We have previously identified iron-responsive element binding protein 2 (IRP2) as a candidate COPD susceptibility gene based on genetic association studies, with IRP2 increased in the lungs of COPD patients. Here we demonstrate that mice deficient in IRP2 are protected from cigarette smoke (CS)-induced COPD. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is characterized by a progressive decline in lung function, caused by exposure to exogenous particles, mainly cigarette smoke (CS). COPD pathogenesis is initiated and perpetuated by an abnormal CS-induced inflammatory response of the lungs, involving both innate and adaptive immunity. Specifically, B cells organized in iBALT structures, as well as macrophages, accumulate in the lungs and contribute to CS-induced emphysema, but the mechanisms thereof remain unclear. more...

(Submitter supplied) We extracted RNA of sorted lung SPC/GFP+ EpCAM+ cells and performed microarray analyses. Total RNA was extracted from sorted Ep-CAMhigh/GFPhigh cells using TRIzol reagent (Invitrogen, Carlsbad, CA) according to the manufacturer’s protocol. The RNA integrity was examined on an Agilent 2100 BioAnalyzer (Agilent Technologies, Santa Clara, CA). Biotinylated ss-cDNA were prepared according to the standard Affymetrix protocol from 100 ng total RNA using the GeneChip WT PLUS Reagent Kit User Manual (Affymetrix/Thermo Fisher Scientific). more...

(Submitter supplied) Although cigarette smoke (CS) is the primary risk factor for COPD, the underlying molecular mechanisms for the significant variability in developing COPD in response to CS are incompletely understood. We performed lung gene expression profiling of two different wild-type murine strains (C57BL/6J, NZW/LacJ) and two genetic models with mutations in COPD GWAS genes (HHIP, FAM13A) after 6 months of chronic CS exposure and compared the results to human COPD lung tissues. more...

(Submitter supplied) Chronic Obstructive Pulmonary Disease, which is comprised of chronic bronchitis and emphysema, is a leading cause of morbidity and mortality. Because tissue destruction is the prominent characteristic of emphysema, extracellular proteinases, particularly those with elastolytic ability, are often considered to be key drivers in this disease. Several human and mouse studies have implicated roles for matrix metalloproteinases (MMPs), particularly macrophage-derived proteinases, in COPD pathogenesis. more...

(Submitter supplied) Pseudomonas aeruginosa is a common bacteria leading to exacerbations of chronic obstructive pulmonary disease (COPD) patients while this bacteria can be easily eradicated by the immune systems of healthy individuals. Human airway organoids derived from healthy individuals and COPD patients were infected with pseudomonas aeruginosa. This project aims (1) to understand the differences in gene expressions in healthy and COPD airway organoids during stable condition, without infection and (2) to investigate differential pathogenic mechanism (i.e. more...

(Submitter supplied) Clinical COPD, characterised by intermittent and infective exacerbations, lacks cellular model systems for the study of host-pathogen relationships. We establish nasopharyngeal and bronchial organoids from COPD patients and healthy individuals. In contrast to healthy organoids, COPD organoids demonstrate the hallmark goblet cell hyperplasia phenotype with reduced ciliary beat frequency, leading to impaired mucociliary clearance. more...
