In vivo cross-protection of HBc-E1/2 to EV71 and CA16.

(A) Groups of one-day old BALB/c mice born to female mice immunized with HBc-E1/2, HBc-E1, HBc-E2 or adjuvant with an immunization dose of 100 μg were challenged with pSVA-MP4 or CA16-190. The mortality were monitored and recorded daily for 20 days. The representative results of two independent experiments are shown. (B) Contrast of pathological changes between HBc-E1/2 group and adjuvant group. Mice born to HBc-E1/2 or adjuvant immunized female mice and challenged with pSVA-MP4 or CA16-190 were sacrificed and the tissues were collected as described in the Materials and Methods. Representative sections analyzed by immunohistochemistry (IHC) or hematoxylin and eosin (HE) staining are shown.
