Fig. 7. Antigen uptake by BMDCs (A) and co-stimulation marker expression on BMDCs (B and C) after co-culture with antigen alone, aluminum-binding antigen or DDAB/PLA-binding antigen. Cell membranes were stained red, and green fluorescence represents HBsAg. Data are expressed as the mean ± SEM (n = 3). *p < 0.05; **p < 0.001; ***p < 0.0001.
