Figure 6. Concomitant tumor immunity induced by administration of MCA-205-E1A-OVA or MCA-205-OVA tumor cells requires T cells.

Figure 6

Mice were injected with PBS or 1×105 live MCA-205-OVA or MCA-205-E1A-OVA tumor cells s.c. in the flank three times, five days apart. Five days after last tumor dose (day 20), mice were challenged with 1×104 MCA-205-OVA tumor cells on the contralateral flank. Mice were administered two injections of 10 μg of anti-CD3 or control IgG before and after MCA-205-OVA tumor challenge on days 17, 19, 22 and 24. Survival curves show the percentage of mice without tumor from MCA-205-OVA cell challenge only. Data was analyzed by the log-rank (Mantel Cox) test. **, p<.01; ***, p<.001.
