T Cell Costimulatory Molecule B7x
T-Cell Costimulatory Molecule B7x
V Set Domain Containing T Cell Activation Inhibitor 1
A B7 antigen subtype that inhibits the costimulation of T-cell activation, proliferation, cytokine production and development of cytotoxicity. The over expression of this protein in a variety of tumor cell types suggests its role in TUMOR IMMUNE EVASION.
