Genomics 44(8):470-84. Briefly, overexpression of the Scnn1b transgene in airway Club cells leads to hyperabsorption of sodium from the airway surface liquid, dehydrated airway surface liquid and mucus, and reduced mucus clearance associated with accumulation of mucus plugs/plaques. more...

(Submitter supplied) Lung diseases, such as cystic fibrosis and COPD, are characterized by mucus obstruction and chronic airway inflammation, but their mechanistic link remains poorly understood. Here, we focused on the role of the mucostatic airway microenvironment on epigenetic reprogramming of airway macrophages (AM) and resulting transcriptomic and phenotypical changes. Using a muco-obstructive mouse model (Scnn1b-transgenic), we identified epigenetically controlled, differentially regulated pathways and transcription factors involved in inflammatory responses and macrophage polarization. more...

(Submitter supplied) Multiple gene expression studies have been performed separately in peripheral blood, lung, and airway tissues to study COPD. We performed RNA-sequencing gene expression profiling of large-airway epithelium, alveolar macrophage and peripheral blood samples from the same set of COPD cases and controls from the COPDGene study who underwent bronchoscopy at a single center. Using statistical and gene set enrichment approaches, we sought to improve the understanding of COPD by studying gene sets and pathways across these tissues, beyond the individual genomic determinants.

(Submitter supplied) Background: When exposed to specific stimuli, macrophages exhibit distinct activation programs, M1 and M2 polarization, that define macrophage function as inflammatory/immune effectors or anti-inflammatory/tissue remodeling cells, respectively. Due to their position on the lung epithelial surface, alveolar macrophages (AM) directly interact with environmental stimuli such as cigarette smoke, the major risk factor for the development of chronic obstructive pulmonary disease (COPD). more...

(Submitter supplied) Rationale: A well-validated animal model of sarcoidosis can help advance our understanding of the pathobiology of this complex disease. We have developed a multiwall carbon nanotube (MWCNT) based murine model that shows marked histological and inflammatory signal similarities to human sarcoidosis. In this study, we compared the alveolar immune cell transcriptional signatures of our murine model with human sarcoidosis to comprehensively assess overlapping molecular programs. more...

(Submitter supplied) The goal of this experiment was to examine the innate immune response to helminth infection in the lung. Hookworms (like many other helminths) use an obligate migration pathway through the lung. Their infection has been characterized in the gut in detail, but early immune responses in the lung have not been fully characterized. Keywords: Time Course

(Submitter supplied) Alveolar macrophage (AM) is a mononuclear phagocyte key to the defense against respiratory infections. To understand AM’s role in airway disease development, we examined the influence of Secretoglobin family 1a member 1 (SCGB1A1), a pulmonary surfactant protein, on AM development and function. In a murine model, high-throughput RNA-sequencing and gene expression analyses were performed on purified AMs isolated from mice lacking in Scgb1a1 gene and were compared with that from mice expressing wild type Scgb1a1 at weaning (4wk), puberty (8wk), early adult (12wk) and middle age (40wk). more...

(Submitter supplied) These studies tested the hypotheses that smoke induces changes in mRNA profiles that are dependent on sex and the health status of the lung, and that the effects of smoke are different after 1 day compared to 5 days of smoke exposure. The ways in which the lungs modulate their response to cigarette smoke after repeated exposures are important for understanding the toxicology of smoke, for developing biomarkers of chronic smoke exposure, and for understanding the therapeutic potential in regulatory signaling pathways that are beneficial or detrimental to lung health. more...

(Submitter supplied) Rationale: Lipopolysaccharide (LPS) is ubiquitous in the environment. Inhalation of LPS has been implicated in the pathogenesis and/or severity of several lung diseases, including pneumonia, chronic obstructive pulmonary disease and asthma. Alveolar macrophages are the main resident leukocytes exposed to inhaled antigens. Objectives: To obtain insight into which innate immune pathways become activated within human alveolar macrophages upon exposure to LPS in vivo.
