Fig. 4From: Suppression of interleukin-6 increases enterovirus A71 lethality in miceThe effect of IL-6 knockout on tissue lymphocyte numbers in EV-A71-infected mice. The numbers of CD19+ cells (a and d), CD4+ cells (b and e), and CD8+ cells (c and f) in the spleens (a to c) and brains (d to f) of wild-type (WT) mice 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 5 samples per group. *P < 0.05 and **P < 0.01Back to article page
