Effects of PD-1 depends on PD-L1. (A–C) Relative PDCD1 mRNA expression (A), relative cell proliferation (B), and immunoblot analysis of the indicated proteins (C) of cells expressing the indicated plasmids. (D–I) Relative cell proliferation (D, F, and H) and immunoblot analysis of the indicated proteins (E, G, and I) of cells expressing the indicated plasmids. (J and K) Relative cell proliferation (J) and immunoblot analysis of the indicated proteins (K) of cells expressing the indicated plasmids and/or treated with control Ig and/or PD-L1 Ig. Three independent experiments were performed for each analysis. Data represent the mean ± SEM (SEM). NS, no significance. *P < 0.05, **P < 0.01, ***P < 0.001.
