The expression levels of CD80 (A), CD86 (B) and HLA-DR (C) on various regimens treated iDCs.

<p>The iDCs were treated with mock, BCG-CS-NPs, UVI-DENV (1, 3 and 10 μg) and DNV (1, 3 and 10 μg) for 24, 48 and 72 h. The expressions of CD80, CD86 and HLA-DR were determined as the mean fluorescence intensity (MFI) by flow cytometry. ^a indicates significant difference between mock- and adjuvant-treated culture. *,** and *** indicate significant difference in MFI level of CD80, CD86 and HLA-DR between DNV and UVI-DENV antigen at 1 μg, 3 μg and 10 μg, respectively.
