The cytokine analysis of IV-infected mice (Fig. 12A through E) after 5 days post-infection (multi-motif strains H99 or KN99α) and 20 days post-infection (Mu-1 or 24064) showed that H99 and KN99α had the highest levels of IL-6 and IL1-β, H99 having a slightly higher level of IL-4, and Mu-1 had the highest IFN-γ levels. The gene discussed is IL4; the disease is infection.
