Th-1 responsiveness of tumor-specific T cells directly correlates with sustained tumor remission post-BMT.

γ-IFN production in individual samples as related to tumor burden. The samples were obtained from the experiment described in Figure 6. Shown are the values for γ-IFN production in response to HA peptide from T cells obtained from individual mice in each group 42 days post-BMT. Treatment group and relative tumor burden observed at autopsy are as indicated. 0 = no tumor, 1+ = 1 to 4 nodules, 2+ = 5 to 10 nodules less than 1 cm, 3+ = more than 10 nodules or any nodule more than 1 cm, 4+ = confluent tumor + ascites.
