Exposure of cystic fibrosis bronchial epithelial cells (CFBE 41 o-) to Pseudomonas aeruginosa (PA01) biofilms

ABSTRACT: In the clinical setting, mutations in the CFTR gene enhance the inflammatory response to P. aeruginosa (PA01) infection, but measurements of the inflammatory response to pathogen stimulation by isolated airway epithelia can yield variable results. In this series, we exposed CFBE41o- cells over-expressing ∆F508/∆F508 CFTR and CFBE41o- cells rescued with wt-CFTR to P. aeruginosa biofilms. P. aeruginosa elicited a more robust increase in cytokine and chemokine expression (e.g., IL-8, CXCL2, CXCL3, CXCR4 and TNF-α) in CFBE-wt-CFTR cells compared to CFBE-∆F508-CFTR cells. These results demonstrate that CFBE41o- cells complemented with wt-CFTR mount a more robust inflammatory response to P. aeruginosa than CFBE41o- ∆F508/∆F508-CFTR cells.

Exposure of cystic fibrosis bronchial epithelial cells (CFBE 41 o-) to Pseudomonas aeruginosa (PA01) biofilms

Project description:In the clinical setting, mutations in the CFTR gene enhance the inflammatory response to P. aeruginosa (PA01) infection, but measurements of the inflammatory response to pathogen stimulation by isolated airway epithelia can yield variable results. In this series, we exposed CFBE41o- cells over-expressing ?F508/?F508 CFTR and CFBE41o- cells rescued with wt-CFTR to P. aeruginosa biofilms. P. aeruginosa elicited a more robust increase in cytokine and chemokine expression (e.g., IL-8, CXCL2, CXCL3, CXCR4 and TNF-?) in CFBE-wt-CFTR cells compared to CFBE-?F508-CFTR cells. These results demonstrate that CFBE41o- cells complemented with wt-CFTR mount a more robust inflammatory response to P. aeruginosa than CFBE41o- ?F508/?F508-CFTR cells. CFBE41o- cells generously provided by Dr. J.P. Clancy (University of Alabama). The series involved 4 treatment groups: unexposed wild type CFTR cells, unexposed ?F508/?F508 CFTR cells, wild type CFTR cells exposed to PA01, and ?F508/?F508 CFTR cells exposed to PA01. Each treatment group involved 4 replicate polarized monolayers. PAO1 was added to the apical side of exposed monolayers at a multiplicity of infection (MOI) of 30:1 for 1 hour in the absence of antibiotics, and then planktonic PAO1 was removed by replacing the apical medium with MEM supplemented with 0.4% arginine (2). Control monolayers were treated identically except that vehicle only (medium used to grow PAO1, MEM supplemented with 0.4% arginine) was added to the apical side of cells. Five hours after washing planktonic P. aeruginosa from the cell monolayers mRNA was isolated.

The miRNome in CFBE41o- cells stably transduced with F508del-CFTR and WT-CFTR

Project description:The purpose of this study was to explore baseline expression of miRNome in Cystic Fibrosis Bronchial Epithelial (CFBE41o-) cells stably transfected with wild type (WT) Cystic Fibrosis Transmembrane Conductance regulator (CFTR) and F508del-CFTR. To fulfill this goal miRNA sequencing was done to see miRNA landscape in CFBE41o- Cells with homozygous F508del mutated CFTR and in CFBE41o- Cells with homozygous WT-CFTR, without any treatment condition.

Gene expression data from human bronchial epithelial cell lines: comparison between normal and CFTR-deficient cells

Project description:Whole transcriptional analysis of normal 16HBE14o- cells, cystic fibrosis (CF) patients-derived CFBE41o- cells, and WT-CFTR-rescued CFBE41o- cells. We utilized the gene expression data to understand the transcriptional regulation underlying the loss of CFTR function.

Quantitative Analysis of mid-L4 WT worms after P. aeruginosa PA01 infection for 12 hours

Project description:To identify candidate genes whose expressions were regulated by P. aeruginosa PA01, we used RNA-Seq analysis to study the transcriptomic profiles of mid-L4 worms exposed to P. aeruginosa PA01 for 12 hours. Differential expression analysis was performed by comparing WT worms exposed to P. aeruginosa PA01 for 12 hours versus worms fed E. coli OP50.

mRNA-Seq of WTBE and CFBE cells

Project description:Cystic fibrosis (CF) is characterized by chronic inflammation and excessive cytokines secretion in the lung. Isogenic human CF bronchial epithelial (CFBE41o-) cell lines stably expressing wt-CFTR (WTBE) or F508del mutant (CFBE) are widely used tools in understanding responses to stimuli or drugs and CF pathogenesis in vitro. However, their intrinsic cellular differences in culture are unknown. Hence, we performed integrative analyses at protein, mRNA and chromatin levels on these isogenic cell lines cultured in submerged and transwell condition. CFBE and WTBE cells displayed different secretion patterns on IL-6, IL-8, CXCL1, CXCL10, and CCL5 . The ALI culture dramatically increased cytokines secretion in both cells. ATAC-seq results showed that CFBE cells exhibited higher genome-wide chromatin accessibility than WTBE cells in both culture methods, but the relative openness of cytokine genes between two cells varied individually. Differentially expressed genes between two cell lines from mRNA sequencing were highly concentrated in immunity-related pathways. While the mRNA stability of CXCL10 and CXCL1 exhibited the most significant differences between cell lines in SUB culture, most cytokines had comparable mRNA stabilities within same culture method. Moreover, polarization of cells via transwell culture remodeled the chromatin accessibility and transcriptome. This multilayered studies presents a comprehensive baseline activities of CFBE and WTBE cells, further facilitating their usage and data interpretation as CF cell models.
