(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) Chronic Obstructive Pulmonary Diseases (COPD) is the third leading cause of death worldwide with no curative therapy available. A novel non-canonical Notch ligand, DNER, has been identified in a GWAS to correlate with disease severity, but its function and contribution to COPD is completely unknown. DNER localization and expression was determined in COPD patients and 6 month cigarette smoke (CS)-exposed mice. 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) 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) Extravasation of monocytes into tissue and to the site of injury is a fundamental immunological process underlying a variety of innate inflammatory responses across multiple organ systems, which requires rapid responses via post translational modifications (PTM) of proteins. Specifically, methylation of protein by arginine methyltransferases (PRMTs) is an epigenetic PTM implicated in inflammatory responses. more...

(Submitter supplied) How LTβR-signalling drives chronic tissue damage particularly in the lung, which mechanisms regulate this process, and whether LTβR-blockade might be of therapeutic value has remained unclear. To study the mechanisms underlying LTβR-inhibition, a transcriptional analysis was performed on lung tissue from B6 mice exposed to cigarette smoke for 6 months and treated therapeutically with LTβR-Ig from 4 to 6 months compared to mice exposed to cigarette smoke for 6 months and treated with control Ig from 4 to 6 months and filtered air control. 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) 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...

(Submitter supplied) Patients with chronic obstructive pulmonary disease (COPD) having higher blood eosinophil levels exhibit worse lung function and more severe emphysema, implying the potential role of eosinophils in emphysema development. However, the specific mechanism underlying eosinophil-mediated emphysema development is not fully elucidated. In this study, single-cell RNA sequencing was used to identify eosinophil subgroups in mouse models of asthma and emphysema and analyze their functions. more...

(Submitter supplied) In 11 control (non-used donors) and 11 COPD (end-stage) explant frozen lungs, 4 cylinders/cores were processed per lung for microCT and tissue transcriptomics. MicroCT was used to quantify tissue percentage and alveolar surface density to classify the COPD cores in mild, moderate and severe zones, as well as to quantify terminal bronchioles. Transcriptomics of each core assessed fold changes in innate and adaptive cells and pathway enrichment score between control and COPD cores. more...
