Project description:We used bulk cell RNA-seq to investigate transcriptional effects of IFN-a, IL-17, and IL-13 in primary human bronchial epithelial cells (HBECs).
Project description:We used ChIP-seq to investigate epigenomic modifications in response to IFN-a, IL-17, and IL-13 in primary human bronchial epithelial cells (HBECs).
Project description:We used scRNA-seq to investigate cell type-specific transcriptional effects of IFN-a, IL-17, and IL-13 in primary human bronchial epithelial cells (HBECs).
Project description:Interleukin (IL)-17 plays an important and protective role in host defence and has been demonstrated to orchestrate airway inflammation by cooperating with and inducing proinflammatory cytokines. Mircoarrays were used to identify immediate-early/ primary response IL-17A-dependent gene transcripts in primary human bronchial ASM cells from mild asthmatic and healthy individuals. To evaluate IL-17A-inducible gene transcripts, primary human bronchial ASM cells from 3 mild asthmatic and 3 healthy donors were treated for 2h with IL-17 [10ng/ml] and were probed with the Affymetrix GeneChip array. The 2h time point was carefully chosen in order to identify primary response gene targets and to avoid confounding autocrine mechanisms mediating indirect, or late-phase gene expression responses. Non-stimulated ASM cells from the same patients were used as controls.
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.
Project description:Primary HBE cells were stimulated with IL-22 and IL-17, and gene expression was studied using an Affymetrix platform microarray, in order to investigate which genes may be upregulated or downregulated in response to these cytokines. Of particular interest was the host defense genes such as antimicrobial peptides, which have been shown to be upregulated by IL-22 and IL-17 in skin keratinocytes. Experiment Overall Design: There were 4 conditions to this study (media, IL-22, IL-17 and IL-22+17) and there were 3 biological replicates of each condition. Experiment Overall Design: Gene expression study using one timepoint of 24 hours after stimulating these primary cells with the above conditions

Project description: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.
