(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) 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 (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 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...

(Submitter supplied) Purpose: The goal of this study is to address if in utero and early life nicotine exposure can prime the offspring to be more succetible to develop emphysema in adulthood Methods: A mouse model of two hits: a prenatal hit and a later insult delivered in adulthood was used in this study. In brief, Nicotine (200 mg/L) was supplied immediately after mating and administered to the females in drinking water supplemented with 2% saccharin for the whole period of gestation and until the post-natal day 16 (nicotine group). more...

(Submitter supplied) Rationale: Multiciliated cell (MCC) loss/dysfunction is common in the small airways of patients with COPD but it is unclear if this contributes to COPD lung pathology. Objectives: To determine whether loss of MCCs causes a COPD-like phenotype in mice and explore a potential role for the transcription factor p73 in COPD. Methods: p73floxE7-E9 mice were crossed with Shh-Cre mice to generate mice lacking MCCs in the airway epithelium. more...

(Submitter supplied) To identify biosignatures that describe these lifestyle susceptibility factors, we performed parallel exposures of regular weight (RW) C57BL/6 and diet-induced obese (DIO) C57BL/6 mice to cigarette smoke, either mainstream (MS) or sidestream (SS), mimicking both the smoker and environmental exposure through second-hand smoke, respectively. Transcriptional responses were measured by global microarray analysis of heart tissue.

(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...
