Rotavirus VP6 Adjuvant Effect on Norovirus GII.4 Virus-Like Particle Uptake and Presentation by Bone Marrow-Derived Dendritic Cells In Vitro and In Vivo

Figure 8

Blocking antibody responses generated by ex vivo-pulsed BMDCs. Norovirus GII.4 virus-like particle- (VLP-) pulsed bone marrow-derived dendritic cells (BMDCs) were transferred intramuscularly two times to mice either alone (Gr II) and in combination with simultaneously (Gr III) or separately (Gr IV) VP6-pulsed BMDCs as described in Materials and Methods. The immune sera of mice were tested individually 1 : 50 (a) or as a pool with serial dilutions (b) against GII.4 VLPs in blocking assays utilizing human saliva type A as the source of histoblood group antigens. The blocking index (%) was calculated as follows: . The error bars represent the standard error between individual mice (a) or two independent assays (b), and the horizontal dashed line illustrates the blocking titer 50%.
