HEK293T Human VTCN1/B7-H4 Stable Cell Line|HEK293T人VTCN1/B7-H4稳定细胞系(靶标：人VTCN1/B7-H4稳定表达细胞系)

V-set domain-containing T-cell activation inhibitor 1 (VTCN1/B7-H4) is a ~30 kDa protein. Negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. Involved in promoting epithelial cell transformation.
