Enterovirus D68 infection induces IL-17–dependent neutrophilic airway inflammation and hyperresponsiveness

Abstract

Enterovirus D68 (EV-D68) shares biologic features with rhinovirus (RV). In 2014, a nationwide outbreak of EV-D68 was associated with severe asthma-like symptoms. We sought to develop a mouse model of EV-D68 infection and determine the mechanisms underlying airway disease. BALB/c mice were inoculated intranasally with EV-D68 (2014 isolate), RV-A1B, or sham, alone or in combination with anti–IL-17A or house dust mite (HDM) treatment. Like RV-A1B, lung EV-D68 viral RNA peaked 12 hours after infection. EV-D68 induced airway inflammation, expression of cytokines (TNF-α, IL-6, IL-12b, IL-17A, CXCL1, CXCL2, CXCL10, and CCL2), and airway hyperresponsiveness, which were suppressed by anti–IL-17A antibody. Neutrophilic inflammation and airway responsiveness were significantly higher after EV-D68 compared with RV-A1B infection. Flow cytometry showed increased lineage–, NKp46–, RORγt+ IL-17+ILC3s and γδ T cells in the lungs of EV-D68–treated mice compared with those in RV-treated mice. EV-D68 infection of HDM-exposed mice induced additive or synergistic increases in BAL neutrophils and eosinophils and expression of IL-17, CCL11, IL-5, and Muc5AC. Finally, patients from the 2014 epidemic period with EV-D68 showed significantly higher nasopharyngeal IL-17 mRNA levels compared with patients with RV-A infection. EV-D68 infection induces IL-17–dependent airway inflammation and hyperresponsiveness, which is greater than that generated by RV-A1B, consistent with the clinical picture of severe asthma-like symptoms.

Female 8- to 10-week-old BALB/c mice were treated with sham or 5 × 106 ePFU of EV-D68. The lungs were harvested after the indicated time points and processed for BAL and mRNA expression. (A) Inflammatory cell counts in BAL at indicated time points. (B) mRNA expression analysis of indicated genes at indicated time points. Data are shown as mean ± SEM; n = 3 mice in each group from two different experiments; *P < 0.05 by 1-way ANOVA, compared with sham.
