Correlations between PD-L1, B7-H3 as well as B7-H4 expression and CD8+ TILs infiltration in PaCa tissues. A Representative microphotographs revealed these molecules expression in PaCa tissues with low and high CD8+ TILs infiltration using IHC staining. Brown, PD-L1, B7-H3, B7-H4, or CD8. Blue, haematoxylin. Bar = 200 μm. Low CD8+ TILs infiltration: proportion < 5%, how CD8+ TILs infiltration: proportion ≥ 5%. B Correlation between PD-L1 expression and CD8+ TILs levels in PaCa tissues. C Correlation between B7-H3 expression and CD8+ TILs levels in PaCa tissues. D Correlation between B7-H4 expression and CD8+ TILs levels in PaCa tissues
