From: Morphine suppresses the immune function of lung cancer by up-regulating MAEL expression
Morphine regulates immune factor expression and reduces LDH release. A The expression of PD-L1, TGF-β, IL-2, and IL-10 was detected by ELISA assay in A549 cells. B The expression of PD-L1, TGF-β, IL-2, and IL-10 was detected by western blot. C The expression of PD-L1, TGF-β, IL-2, and IL-10 was detected by ELISA assay in H460 cells. D The LDH release was detected using the LDH kit.*P < 0.05, **P < 0.01 versus control
