背景信息

B7-H4, also known as V-set domain containing T cell activation inhibitor 1 (VTCN1/B7x/B7 homolog4/B7S1), belongs to the coinhibitory B7 family ligands. B7-H4 is a type I transmembrane protein and is thought to be an immune checkpoint molecule in the context of tumor immunity. B7-H4 is nominally expressed in normal tissues yet is highly expressed in many types of cancer, including breast cancer, cholangiocarcinoma, endometrial carcinoma, non-small cell and squamous cell lung carcinoma, and ovarian carcinoma. High B7-H4 expression often correlates with shorter cancer patient survival.
