Cytokine production of splenocytes among immunized mice was determined by CBA 2 weeks after the third immunization. Splenocytes were stimulated for 24 h with pooled peptides consisting of the NTD, and the supernatants were harvested. Cytokine concentration was detected using a CBA kit. The cytokines of Th1, Th2, and Th17 are shown in the figures. (A) IL-2 and IFN-γ. (B) IL-6 and IL-10. (C) IL-17A. Statistical significance was set at ∗P < 0.05.
