NKT cells do not affect tumor clearance by Tcons. To assess tumor clearance by Tcons, recipient mice were engrafted with luc⁺Bcl-1 tumor cells 7 days before transplantation. Tumor burden was then monitored via BLI. (A) BLI at day 9 after transplantation of the luc⁺Bcl-1 lymphoma with TCD-BM alone, Tcons alone, NKT alone, or Tcons + NKT indicated that both groups receiving Tcons were completely cured of their tumors. Shown are 2 representative mice from each group. (B) BLI graph showing tumor load during transplant. Shown is the mean ± SE from one of 2 independent experiments with 5 mice per group. Groups: TCD-BM only (●); Bcl-1 control (◇); Bcl-1 + 5 × 10⁵ Tcons (▿); Bcl-1 + Tcons + 2.5 × 10⁴ NKT (○); and Bcl-1 + 2.5 × 10⁴ NKT (□).
