Cytokine production in EV71-infected RD cells. RD cells were infected with EV71 (MOI = 5). At 0 h, 20 h and 32 h, cell culture supernatants were collected and the levels of cytokines were performed by ELISA. The data were expressed as mean ± SE from three independent experiments and analyzed by two-way ANOVA with Bonferroni post hoc tests. *p < 0.05, **p < 0.01, and ***p < 0.001.
