Project description:Phenotypic responses of differentiated asthmatic human airway epithelial cultures to rhinovirus
| PRJNA260343 | ENA
Project description:Expression data from airway brush biopsy samples, differentiated primary cultures of human airway epithelia, CaLu3 cultures at the air liquid interface, and primary cultures of human airway epithelia submerged in nutrient media Organotypic cultures of primary human airway epithelial cells have been used to investigate the morphology, ion and fluid transport, innate immunity, transcytosis, infection, inflammation, signaling, cilia and repair functions of this complex tissue. However, we do not know how close these cultures resemble the epithelia in vivo. In this study, we examine the genome-wide expression profile of human airway epithelial cells in vivo obtained from brush biopsies of the trachea and bronchus of healthy volunteers and compare it to the expression profile of primary cultures of human airway epithelia grown at the air-liquid interface. For comparison we also investigate the expression profile of Calu3 cells grown at the air-liquid interface and primary cultures of human airway epithelia submerged in nutrient media. We compare the transcriptional profile of human in vivo airway epithelia from trachea and bronchus to differentiated primary human airway epithelia cultures, also from trachea and bronchus, and grown at the air-liquid interface. We also included the profile of Calu3 cultures grown at the air-liquid interface and primary cultures submerged in nutrient media.

Project description:We report the application of RNA sequencing technology for high-throughput profiling of gene expression responses to human rhinovirus infection at 24 hours in air-liquid interface human airway epithelial cell cultures derived from 6 asthmatic and 6 non-asthmatic donors. RNA-seq analysis identified sets of genes associated with asthma specific viral responses. These genes are related to inflammatory pathways, epithelial remodeling and cilium assembly and function, including those described previously (e.g. CCL5, CXCL10 and CX3CL1), and novel ones that were identified for the first time in this study (e.g. CCRL1, CDHR3). We concluded that air liquid interface cultured human airway epithelial cells challenged with live HRV are a useful in vitro model for the study of rhinovirus induced asthma exacerbation, given that our findings are consistent with clinical data sets. Furthermore, our data suggest that abnormal airway epithelial structure and inflammatory signaling are important contributors to viral induced asthma exacerbation. Differentiated air-liquid interface cultured human airway epithelial cell mRNA profiles from 6 asthmatic and 6 non-asthmatic donors after 24 hour treatment with either HRV or vehicle control were generated by deep sequencing, using Illumina HiSeq 2000.

Project description:We report the application of single-cell-based sequencing technology for high-throughput profiling of cell types and and transcriptional state of cells in the complex tissue of the human airway epithelium. Our model system is that of polarized human airway epithelial cultures, differentiated from hTert-immortalized basal-like precursor cells.

Project description:This study investigated the acute and reparative responses as a function of age and sex in primary human bronchial epithelial (HBE) cultures over a 14-day post-SARS-CoV-2 infection (dpi) protocol. Methods: Bulk RNA-seq was performed on well-differentiated human bronchial epithelial (HBE) cell culture lysates with/without SARS-CoV-2 inoculation. Results: SARS-SoV-2 infection peaked at 3 dpi with an ~ 2 log titer suppression at 14 dpi. Airway epithelia repaired to an abnormal mucus metaplastic/inflammatory state that reflected potentially beneficial and adverse consequences at 14 dpi. No age- or sex-dependent effects on SARS-CoV-2 infection were detected. Conclusions: Human airway epithelial repair post-SARS-CoV-2 is prolonged and incomplete in vitro over 14 days, and persistently abnormal repair may contribute to phenotypes of people with long-COVID pulmonary syndrome.

Project description:Normal human bronchial epithelial (NHBE) cells cultured in an air-liquid interface (ALI) system form a polarized, pseudostratified epithelium composed of basal, ciliated and goblet cells that closely resemble the in vivo airway epithelium structure. ALI cultures of NHBE cells provide a unique in vitro system to investigate airway epithelial biology, including developmental, structural and physiologic aspects. In this study, we wanted to investigate mRNA expression patterns during airway epithelium differentiation. By using microarrays, we studied the changes in expression of mRNAs in normal human bronchial epithelial cells as they differentiate from an undifferentiated monolayer to a differentiated pseudostratified epithelium after 28 days of air-liquid interface (ALI) culture, when epithelial cells differentially express basal, ciliated and goblet cell markers.

Project description:The human airways are complex structures with important interactions between cells, extracellular matrix proteins and the biomechanical microenvironment. A robust, well-differentiated in vitro culture system that accurately models these interactions would provide a useful tool for studying normal and pathological airway biology. Here, we report the analysis of a physiologically relevant air-liquid interface (ALI) 3D airway ‘organ tissue equivalent’ (OTE) model with three novel features: native pulmonary fibroblasts, solubilized lung extracellular matrix (ECM), and hydrogel substrate with tunable stiffness and porosity. We demonstrate the versatility of the OTE model by evaluating the impact of these features on HBE cell phenotype. Variations of this model were analyzed during 28 days of ALI culture by evaluating epithelial confluence, trans-epithelial resistance (TEER), and epithelial phenotype via multispectral immuno-histochemistry and next-generation sequencing (NGS). Cultures that included both solubilized lung ECM and native pulmonary fibroblasts within the hydrogel substrate formed well differentiated ALI cultures that maintained a barrier function and expressed similar levels of goblet, club and ciliated markers to native airway tissue. Modulation of hydrogel stiffness did not negatively impact HBE differentiation and could be a valuable variable to alter epithelial phenotype. This study highlights the capability and versatility of a 3D airway OTE model to model the multiple components of the human airway 3D microenvironment.

Normal human bronchial epithelial cells were cultured in an air-liquid interface (ALI) system and harvested at three different time-points: subconfluent, confluent and day 28 of ALI. Samples were processed for total RNA extraction and hybridization on Affymetrix microarrays. All the experiments were performed by triplicate.
