SKOV3 cells were injected into nude mice, and the tumor cells were allowed to grow out and engraft for one week before the mice received twice-weekly i.v. injections with human Vγ2Vδ2 T cells, followed by twice-weekly i.p. injections with either 8 mg/kg Vγ2 x PD-L1 or Vγ2 x Null, or PBS. This evidence concerns the gene CD274 and neoplasm.
