PD‐L1, B7‐H3 and VISTA are highly expressed in gestational trophoblastic neoplasia

Aims The B7 family check‐point molecules are potential therapeutic targets in cancer immunotherapy. However, their expression status in human gestational trophoblastic neoplasia (GTN) remains unknown. We investigated the expression profiles of the B7 family check‐point proteins PD‐L1, PD‐L2, B7‐H3, B7‐H4, VISTA and B7‐H6 in GTN and their clinical significance. Methods and results We identified 112 patients with GTN, including 68 with...
