Figure 7. Absence of T-bet and ROR[gamma]t does not alter donor antitumor (p815) response. Lethally irradiated (1200 cGy) B6D2F1 mice were transplanted with grafts from WT or RORγt−/−/T-bet−/− donors, containing 5 × 106 TCD-BM cells and 2-4 × 106 T cells from WT, T-bet−/−/RORγt−/− donors. No (A) or 4 × 103 P815 tumor cells (B-C) were added into donor graft. Survival by Kaplan-Meier analysis of B6D2F1 recipients (A-B) and mortality because of tumor relapse (C) are shown. Data are combined from 2 separate experiments (n = 13, TCD-BM + T-cell groups; n = 4, TCD-BM control group). Asterisk indicates statistical significance: *P < .05 and **P < .01.
