IL-13 stimulation of primary human bronchial epithelial cells in control individuals and patients with asthma.

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. Overall design: RNA sequencing of gene expression in differentiated primary human bronchial epithelial cells upon IL-13 treatment in healthy controls and patients with asthma.
