Project description:scRNA-seq of air-liquid interface airway epithelial cultures derived from a human fluorescent reporter hPSC line labeling MUC5B-expressing cells
Project description:The dominant risk factor for the development of idiopathic pulmonary fibrosis (IPF) is a common variant in the promoter region of the airway mucin MUC5B, variant rs35705950. The MUC5B promoter variant enhances MUC5B expression in the terminal respiratory bronchiole, where it is normally absent. We pursued a spatial gene expression approach to understand how the MUC5B variant influences IPF in age-matched unaffected and IPF lung tissue specimens.
Project description:IL13 exposure results in a distinct gene expression profile in human airway epithelia. We investigated whether this expression profile can be used to identify compounds able to block goblet cell metaplasia We used microarrays to determine transcriptional changes in cultures of primary human airway epithelia grown at the air-liquid interface after exposure to 20 ng/mL recombinant human IL13
Project description:The goal of this study was to compare cell composition and gene expression of different cell types in healthy primary human airway epithelia cultured at the air-liquid interface
Project description:The goal of this study was to compare cell composition, gene expression, and infectivity of different cell types in human airway epithelia following exposure to measles virus. Samples included control epithelia exposed to a mock infection and measles-virus-exposed epithelia that were sorted according to detection of green fluorescent protein (GFP) prior to library preparation and sequencing.
Project description:To identify genes regulating the jamming transition in healthy distal airway epithelia compared to the dysregulated state in idiopathic pulmonary fibrosis epithelia (IPF) we analyzed RNA from three (3) healthy and four (4) IPF patient cells grown at air-liquid-interface (ALI). This bulk analysis of 3 timepointes (days 4, 8, and 14 of ALI) spanning the jamming transition revealed an enrichment for ERBB- and YAP-related genes.
Project description:The goal of this study was to examine changes to gene expression induced by IL-13 treatment of air-liquid interface cultures of healthy primary human airway epithelia over time.
