CXCL8 and infection: Cytokines not significantly induced on any post-infection day in asthma were IL-1β, IL-12p70, IL-16, IL-18, IL-25, GM-CSF, TSLP, CCL13/MCP-4, CCL26/eotaxin3 and CXCL8/IL-8 (Tables S5 and S6–9), though CCL13/MCP-4 was significantly increased after infection in asthma compared to healthy controls when assessing AUC (Table S4), suggesting greater data variability than with other cytokines/chemokines.
