Project description:The purpose of the study is to compare the transcriptomic profile of the airway epithelial cell line Calu-3 in reponse to Pseudomonas aeruginosa virulence factor flagellin. CF is caused by mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. CFTR gene in Calu-3 cells was knockdown by CRISPR-Cas9 (TS) and a control cell line (CTL) was aslo generated using a non-targeting guide RNA. CTL and CFTR KD Calu3-cells were grown on Transwell filters, polarized at the air-liquid interface and exposed to flagellin for 6 hours. We considered 2 non-stimulated (ND) conditions: CTL-NS and TS-NS, and 2 conditions stimulated with flagellin (Flag): CTL-Flag and TS-Flag.

Project description:Here, we aim to understand the role of P38 in the airway epithelial cells response to flagellin. We report the gene expression profile of pig airway epithelial cells cultured under air-liquid conditions, pre-incubated or not with the P38 inhibitor SB203580 (20 µM, Tocris Bioscience) for 1 h and then stimulated with 100 ng/ml of a mutated flagellin (FliCΔ174-400) for 2h or 24h. Our data show that flagellin stimulation induce the expression of pro-inflammatory cytokines mainly through the NFkB pathway, with little impact of P38 inhibition in the cells response.

Project description:Airway epithelial cells (AEC) are critical components of the inflammatory and immune response during exposure to pathogens. AECs in monolayer culture and differentiated epithelial cells in air-liquid interface (ALI) represent two distinct and commonly used in vitro models, yet differences in their response to pathogens have not been investigated. In this study, we compared the transcriptional effects of flagellin on AECs in monolayer culture versus ALI culture using exon microarrays and RNAsequencing. We found that AECs cultured in monolayer and ALI have strikingly different transcriptional states at baseline. When challenged with flagellin, monolayer AEC cultures greatly increased transcription of numerous genes mapping to wounding response, immunity and inflammatory response. In contrast, AECs in ALI culture had an unexpectedly muted response to flagellin, both in number of genes expressed and relative enrichment of inflammatory and immune pathways. In conclusion, In vitro culturing methods have a dramatic effect on the transcriptional profile of AECs at baseline and after stimulation with flagellin. These differences suggest that epithelial responses to pathogen challenges are distinctly different in culture models of intact and injured epithelium.

Project description:Ets homologous factor (EHF) is an Ets family transcription factor expressed in many epithelial cell types including those lining the respiratory system. Disruption of the airway epithelium is central to many lung diseases, and a network of transcription factors coordinates its normal function. EHF can act as a transcriptional activator or a repressor, though its targets in lung epithelial cells are largely uncharacterized. Chromatin immunoprecipitation followed by deep sequencing (ChIP-seq), showed that the majority of EHF binding sites in lung epithelial cells are intergenic or intronic and coincide with putative enhancers, marked by specific histone modifications and increased DNase hypersensitivity.

Project description:This series contains 5 groups of U133A arrays with targets from Calu-3 cell line post-infection with P aeruginosa strains. Calu-3 human lung epithelial cells were seeded onto 6-well plates and grown to about 80% confluency. Epithelial monolayers were infected with 108 CFUs per ml of each bacterial strain for 60 min and then washed extensively with phosphate-buffered saline. The cultures were subsequently incubated in fresh RPMI 1640 medium supplemented with 10% fetal bovine serum and 100 µg/ml gentamicin. After 6 h, total RNA from the cells was prepared with RNAzol and further purified with RNEasy for microarray hybridization. All arrays processed and globally scaled to 500 using MAS 5.

Disruption of the airway epithelium is central to many lung diseases, and a network of transcription factors coordinates its normal function. EHF can act as a transcriptional activator or a repressor, though its targets in lung epithelial cells are largely uncharacterized. RNA-seq after EHF depletion or overexpression showed significant alterations in the expression of genes involved in response to wounding. EHF knockdown also targeted genes in pathways of epithelial development and differentiation and locomotory behavior. mRNA profiles from Calu-3 cells treated with negative control (NC) or EHF siRNA, in quintuplicate. mRNA profiles from 3 pcDNA (empty vector control) clones and 3 pcDNA-EHF overexpression A549 clones, 3-4 replicates each.

Project description:Airway epithelial cells represent the first line of defense against respiratory pathogens. Flagellin drives the motility of many mucosal pathogens and has been suggested as an immune enhancing adjunctive therapeutic in infections of the airways. This study leveraged single-cell RNA sequencing to determine cell-specific effects of flagellin in primary human bronchial epithelial cells growing in air-liquid interface. Seven cell clusters were identified, including ciliated cells, ionocytes and several states of basal and secretory cells, of which only inflammatory basal cells and inflammatory secretory cells demonstrated a proportional increase in response to flagellin. Inflammatory secretory cells showed evidence of metabolic reprogramming toward aerobic glycolysis, whilst in inflammatory basal cells transcriptome profiles indicated enhanced oxidative phosphorylation. Inhibition of mTOR prevented the shift to glycolysis and reduced inflammatory gene transcription specifically in inflammatory secretory cells. This data demonstrates the functional heterogeneity of the human airway epithelium upon exposure to flagellin.

EHF occupies many genomic sites that are close to genes involved in intercellular and cell-matrix adhesion. Examination of EHF binding plus two histone modifications in Calu-3 cells. There are two replicates of the EHF ChIP-seq plus an input sample (control). There is one replicate each of the two histone modifications, plus a second input sample (control).
