To determine the possible impact of ST2 on pulmonary inflammation during influenza infection, we measured lung levels of cytokines (IFN-γ, TNF-α, IL-1β, IL-6, IL-10, IL-33, IL-13, IL-5) and chemokines (KC, MIP-2) at 3, 8 and 14 days following influenza inoculation (Figure 2). The gene discussed is TNF; the disease is influenza.
