摘要:
The invention provides novel polypeptides useful for co-stimulating T cells, isolated nucleic acid molecules encoding them, vectors containing the nucleic acid molecules, and cells containing the vectors. Also included are methods of making and using these co-stimulatory polypeptides.
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.

The invention provides novel B7-H3 and B7-H4 polypeptides useful for co-stimulating T cells, isolated nucleic acid molecules encoding them, vectors containing the nucleic acid molecules, and cells containing the vectors. Also included are methods of making and using these co-stimulatory polypeptides.
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.
摘要:
B7-HS costimulatory polypeptides, nucleic acids encoding such polypeptides, and methods for using the polypeptides and nucleic acids to enhance a T cell response are provided herein.

摘要:
Described are uses of an agent that reduces B7-H1 interaction with PD-1, and particularly monoclonal antibodies that bind to B7-H1 and interfere with B7-H1 interaction with PD-1 in combination with a vaccine to provide synergistic effects. The application provides methods of treatment and vaccination based on the combination of these compounds on T cell responses.
