B7-H4 Protein, Human (Biotinylated, HEK293, His-Avi)
Based on 1 Customer Validation
The B7-H4 protein acts as a negative regulator, inhibiting T cell-mediated immune responses, including activation, proliferation, cytokine production, and cytotoxicity. When expressed on tumor macrophages, it cooperates with regulatory T cells to suppress tumor-associated antigen-specific T cell immunity. B7-H4 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived B7-H4 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

B7-H4 protein functions as a negative regulator of the T-cell-mediated immune response, exerting inhibitory effects on T-cell activation, proliferation, cytokine production, and the development of cytotoxicity. Particularly significant when expressed on the cell surface of tumor macrophages, B7-H4, in collaboration with regulatory T-cells (Treg), plays a crucial role in suppressing tumor-associated antigen-specific T-cell immunity. Additionally, B7-H4 is implicated in the promotion of epithelial cell transformation, indicating its multifaceted involvement in modulating immune responses and cellular processes associated with tumor development.
