Background

B7-H3 (CD276) is a type I transmembrane protein that belongs to the B7 immunoregulatory family. B7-H3 participates in the regulation of T-cell-mediated immune response probably by functioning as both a T cell costimulator and coinhibitor. B7-H3 plays an essential role in cell proliferation, invasion, and migration in malignancies. Overexpressed in different types of human cancers, B7-H3 has been implicated in cancer progression and metastasis and becomes an attractive target for cancer immunotherapy.
