IL4 and infection: Among them, IFN-α (1000 pg/ml at 16 h), IL1RA (750 pg/m), IL4 (13 pg/m) and the proinflammatory cytokines IL-6 (1250 pg/m) and TNF-α (1700 pg/m) were induced much more rapidly after MV-EDIII-ectoM infection and at levels 8–10 times higher than after MV-EDIII infection (Figure 6).
