Tumor volumes were monitored on the indicated days (n= 11 mice/1928zT2 and M28zT2 group,n= 10 mice/T28zT2 CD4 group,n= 15 mice/T4M828zT2 group). The majority of mice in all groups exhibited serious symptoms of GVHD, halting animal experiments on day 35 post-injection. Data are shown for 2 independent experiments; displayed as the mean±SEM values; a repeat measures ANOVA with Tukey’s multiple comparisons test; ****p≤0.0001 (T4M28zT2 T cells vs. 1928zT2 T cells on day 35, T4M28zT2 T cells vs. M28zT2 T cells on day 35, and T4M28zT2 T cells vsT28zT2 CD4 T cells on day 35).
