Fig. 6. Expression of PD-L1 and chemokine by cocktail treatment of immuno-DCD[siRNA] and immuno-PCD[SAHA] liposomes.
A549 cells were incubated with immuno-DCD[siRNA] for 24 h and then treated with immuno-PCD[SAHA] (10 μM) for 48 h. The expression levels of (A) PD-L1 and (B) chemokine (CCL5) were determined by ELISA. The data are presented as means ± SD for triplicate experiments. A; *P<0.05 compared with immuno-PCD[SAHA]. B; ***P<0.001 compared with control, *P<0.05 compared with control.
