Figure 8.
Cross-recognition of wt/dr proteins and peptides in RT gene-immunized mice. Mice were immunized as described in Figs 2 and 3. RT1.14 and RTwt proteins were used to stimulate splenocytes of mice immunized (either in the prime or prime-boost regimen) with RTwt-opt-in and RT1.14-opt-in encoding plasmids, respectively (a–c). RT205–220 wt/dr peptides (Table 1; d) were used to stimulate splenocytes of mice immunized (in the prime regimen) with the RTwt-opt-in encoding plasmid (d). Results of the Flurospot test detecting IFN-γ, IL-2, and dual IFN-γ/IL-2 production are presented as the average number of cells, registered as signal-forming units (sfu) per million splenocytes secreting cytokines, and the error bars represent the SD. All assays were performed in duplicate. **p < 0.01; p-values in the interval 0.05 to 0.1 indicate tendencies; p > 0.1 for comparison of responses to RT205–220 wt and RT205–220 dr (d). Statistical comparisons were performed using Mann-Whitney tests.
