To determine the mechanisms of graft-versus-tumor (GVT) activity in the absence of graft-versus-host disease (GVHD) against a solid tumor, we established two allogeneic bone marrow transplantation models with a murine renal cell carcinoma (RENCA). The addition of 0.3 x 10⁶ donor CD8⁺ T cells to the allograft increased the survival of tumor-bearing mice without causing GVHD. The analysis of CD8⁺ T cells deficient in cytotoxic molecules demonstrated that anti-RENCA activity is dependent on IFN- and Fas ligand (FasL), but does not require soluble or membrane-bound TNF-, perforin, or TRAIL. Recipients of IFN-^–/– CD8⁺ T cells are unable to reject RENCA compared with recipients of wild-type CD8⁺ T cells and, importantly, neither group develops severe GVHD. IFN-^–/– CD8⁺ T cells derived from transplanted mice are less able to kill RENCA cells in vitro, while pretreatment of RENCA cells with IFN- enhances class I and FasL expression and rescues the lytic capacity of IFN-^–/– CD8⁺ T cells. These results demonstrate that the addition of low numbers of selected donor CD8⁺ T cells to the allograft can mediate GVT activity without lethal GVHD against murine renal cell carcinoma, and this GVT activity is dependent on IFN- and FasL.
