Additional file 1: Figure S1. of Suppression of interleukin-6 increases enterovirus A71 lethality in mice

Effects of IL-6 knockout on numbers of activated T cells in infected mouse brains. The numbers of activated (CD69+) CD4+ and (CD69+) CD8+ T cells in the brain of wild-type (WT) and IL-6 −/− mice, which were mock-infected (−) or infected with EV-A71 (+) for 10 days, are shown. Data show means + SEM (error bars) of 3 samples per group. *P
