PD-L1-AAV particles reduced PD-L1 expression in vivo. (4 A) PD-L1 expression in the isolated tumors was measured by western blot analysis (each group, n = 8). GAPDH was used as a loading control. (4B) Western blot results were analyzed using the relative quantification (RQ) value. All values are presented as the mean ± SE (each group, n = 8). Statistical significance was determined using the unpaired Student’s t-test. * p < 0.05
