From: Clinical significance and correlation of PD-L1, B7-H3, B7-H4, and TILs in pancreatic cancer
Expression levels of PD-L1, B7-H3, and B7-H4 in PaCa tissues. A Representative microphotographs revealed these molecules expression in para-tumor tissues and tumor tissues using IHC staining. Brown, PD-L1, B7-H3, or B7-H4. Blue, haematoxylin. Bar = 200 μm. B The expression of PD-L1 in tumor (n = 78) and para-tumor (n = 72) tissues. C The expression of B7-H3 in tumor (n = 78) and para-tumor (n = 72) tissues. D The expression of B7-H4 in tumor (n = 78) and para-tumor (n = 72) tissues
