| Research Abstract |
To improve clinical outcomes of DC-based tumor immune therapy, we carried out basic study for combination with gene therapy. In this study 1) we cloned canine genes of cytokine which activate cancer immunity, such as IFNγ, and certified that cloned genes produce functional cytokines ; 2) we succeeded to obtain significant clinical responses, including complete healing of malignant tumors by inoculation of DCs with injection of IFNγ into tumors exerted ; 3) we found that DCs inhibited in vitro tumor growth more significantly when tumor cells were transfected with IFNγ gene. These results suggest that transfection of IFNγ gene into tumor cells in vivo may significantly enhance the effect of DC-based tumor immune therapy.
