CD4⁺ iNKT cells preserve Tcon-mediated GVT reactions against A20 lymphoma cells. (A) Tumor growth of luc⁺ A20 cells was assessed by BLI. Shown are representative bioluminescence images of day +16. (B) Bioluminescence signal intensity and (C) survival of BALB/c mice throughout the whole experiment. Shown is 1 of 2 independent experiments with 5 animals per group except irradiation control (n = 3). †Indicates all animals from the respective group died or needed to be euthanized. Error bars indicate standard error of the mean.
