Inoculation of ferrets with influenza B viruses causes inflammation in tissues of the respiratory tract. mRNA expression of IL-6 (a), IL-8 (b), IL-10 (c), IP-10 (d), TNF-α (e) and TGF-β (f) mRNA were increased at 2, 4 and 6 days post inoculation (DPI) in tissues of the respiratory tracts of ferrets inoculated with influenza B virus. mRNA expression was detected via real-time PCR (SYBR Green) using GAPDH expression as a control. Fold changes are in comparison to uninoculated animals. Ferrets were inoculated with either Yamagata strain B/Guangzhou/12/2016 (Y12) or Victoria strain B/Guangzhou/0215/2012 (V0215)
