Epithelial miR-141 regulates IL-13-induced airway mucus production

ABSTRACT: We performed RNA sequencing of gene expression in primary human bronchial epithelial cells that have undergone CRISPR/Cas9-based targeting of MIR141. The goal was to identify the role of miR-141 in goblet cell mucus production. CRISPR-targeted cells were differentiated at air-liquid-interface and stimulated with IL-13 to induce goblet cell hyperplasia.

Epithelial miR-141 regulates IL-13-induced airway mucus production [miRNA-seq]

Project description:We performed small RNA sequencing (TruSeq) of gene expression on bronchial cells from human bronchial epithelial brushings from 16 independent subjects whose samples were classified as either healthy controls (with no asthma or lung disease) or steroid-naive asthmatics (subjects with asthma not using inhaled corticosteroids (ICS) for 6 weeks before enrollment that were studied at baseline ('Steroid-naive asthma - Baseline') or after 8 weeks of treatment with budesonide, 200 μg twice a day, ('Steroid-naive asthma - Post-ICS treatment')). The goal was to assess abundance of miRNAs in all the samples collectively.

Expression data from human bronchial epithelial cells (treatment with IL-4)

Project description:Goblet cell hyperplasia (GCH) is a feature of respiratory diseases characterized by mucus hypersecretion. GCH is driven by Th2 cytokines such as IL-4. To investigate the gene expression changes associated with GCH, we treated human bronchial epithelial cells with IL-4. By microarray analysis and functional studies, we found that IL-4 promotes a profound change that results in enhanced bicarbonate secretion. This change may be required to support mucus release.

Prevalence and Mechanisms of Mucus Plugging in COVID-19 Lung Disease

Project description:Purpose: To investigate molecular mechanisms of SARS-CoV-2-induced mucin expression and synthesis and test candidate countermeasures. Methods: Bulk RNA-seq was performed on well-differentiated human bronchial epithelial (HBE) cell culture lysates with/without SARS-CoV-2 inoculation. Results: SARS-CoV-2-infected HBE cultures exhibited peak titers 3 days post inoculation, whereas induction of MUC5B/MUC5AC peaked 7-14 days post inoculation. Conclusions: SARS-CoV-2-infection to HBE culture causes mucus goblet cell metaplasia and increased expression of MUC5B-dominated mucin overproduction.

Epithelial miR-141 regulates IL-13-induced airway mucus production [single-cell RNA-seq]

Project description:We performed single cell RNA sequencing on bronchial cells from human bronchoalveolar lavage fluid from 4 independent study participants who had asthma and who underwent lung segmental allergen challenge with diluent or allergen (either house duse mite or cat). The goal was to assess total mRNAs in single cell preparations of bronchoalveolar lavage cells.

IL-13 stimulation of primary human bronchial epithelial cells in control individuals and patients with asthma.

Project description:We performed RNA sequencing of gene expression of differentiated primary human bronchial epithelial cells derived from control and asthmatic patients, stimulated with IL-13. The Type 2 Asthma mediator IL-13 was described to induce airway hyperresponsiveness, goblet cell metaplasia, mucus hypersecretion and airway remoddeling including impairment of epithelial barrier integrity. We investigated differential expression of SARS-CoV-2 related host gene expression as well as genes involved in N-linked glycosylation upon IL-13 in bronchial epithelial cells. Top IL-13 affected pathways included ion- and transmembrane transport, lipid metabolic processed and protein glycosylation.

Cathelicidin deficiency disrupts goblet cell mucus secretion but not mucus associated proteins in Citrobacter rodentium-induced colitis

Project description:Colonic goblet cells respond to invading enteropathogens by secreting Muc2 mucin and other specific goblet cell proteins that physically entrap and expel microbes away from the epithelium. At present, it is unclear how innate effectors in the gut, including small cationic cathelicidin peptides secreted by the intestinal epithelium and leukocytes, contribute to mucus barrier defense during infections. In this study, we used cathelicidin-deficient (Camp-/-) mice, colonoids, and human colonic LS174T goblet cells to elucidate the mechanisms by which cathelicidin regulates goblet cell secretions in innate host defense against attaching/effacing Citrobacter rodentium. We showed that even though Camp-/- littermates infected with C. rodentium displayed increased fecal shedding and epithelial colonization, Muc2 mucin granules were retained in bloated colonic goblet cells that impaired mucus secretion and expressed less mucus-associated proteins, as quantified by proteomic analysis. C. rodentium infected Camp-/- littermates showed impaired reactive oxygen species (ROS) production and transcriptomic profiling associated with decreased ROS biosynthesis and an increase in ROS negative regulators. Camp-/- bone marrow derived macrophages produced less ROS than their wild-type counterparts. In LS174T goblet cells, human cathelicidin LL-37 promptly induced the secretion of goblet cell-associated TFF3 and RELMβ, which was dependent on ROS production. These findings demonstrate that cathelicidin signaling in colonic goblet cells regulates mucus and mucin-associated protein secretion via an ROS-dependent mechanism to clear bacterial infections and restore gut homeostasis.
