    摘要: The present invention is directed to a method of inhibiting tumor cell growth. Tumor cells from a pateint are recombinantly engineered to express the B7 surface protein and these cells are then readminsistered to the pateint. The presence of the B7 molecule on the tumor cell surface stimulates a broad immunologic response against both the B7-transfected and non-transfected tumor cells and results in the immunologic killing of localized and metastatic tumor cells. B7 transfection of the tumor cells, or cell membranes, serves as a stimulant to engender a potent immunologic response against the surface antigens present on the tumor cells.

    摘要: Compositions and methods for costimulating T cells (i.e., increasing antigen-specific proliferation of T cells, enhancing cytokine production by T cells, stimulating differentiation ad effector functions of T cells and/or promoting T cell survival) are provided. Suitable compositions include variant B7-DC polypeptides, fragments and fusion proteins thereof. Variant B7-DC polypeptides have reduced binding affinity for the inhibitory PD-1 ligand and substantially retain the ability to costimulate T cells. Methods for using variant B7-DC polypeptides to stimulate immune responses in subjects in need thereof are provided.
