Transcriptome analysis to investigate COPD exacerbations to influenza infection
Ontology highlight
ABSTRACT: Lung infection by influenza A viruses is a common cause of disease exacerbations in patients with chronic obstructive pulmonary disease (COPD), however, this process is difficult to study in human patients. Here we used a microfluidic human lung airway-on-a-chip (Airway Chip) lined by primary human bronchial epithelium interfaced with primary human pulmonary microvascular endothelium to model this process in vitro. Airway Chips containing bronchial epithelial cells from COPD patients successfully replicated the increased sensitivity to the lung airway to infection by both influenza H1N1 and H3N2 viruses compared to chips lined by epithelium from healthy donors, including enhanced viral loads and increased production of inflammatory cytokines. Transcriptomics analysis of the healthy and COPD epithelium following infection with influenza H1N1 virus on-chip resulted in identification of several novel markers of COPD
