^*Peripheral blood mononuclear cells were cultured in the presence of IL-2 as detailed in the Materials and Methods section before culture in the presence or absence of Caki-1 RCC cells.

^†t test: CD16⁺ versus CD16⁺/Caki-1, P = .02; CD16⁺/Caki-1 versus CD16^-/Caki-1, P = .007; bolded numbers, statistically significant differences.
