OPN deficiency impaired DCs maturation and function after HBV antigenic stimulation in vitro.
Notes: DCs derived from BM of the WT and OPN−/− mice were stimulated by HBV antigens. The histograms (A) and percentages (B–D) of CD80, CD86, and MHC-II molecules on the DC surface were detected by flow cytometry. Overlay plots are representative and show isotype control (shadow) and the expressions of the indicated molecules on DCs from WT mice (green line) or OPN−/− mice (red line) in each group. (E) Levels of IL-12 in the BMDC culture supernatants following different stimulations were measured by ELISA. *P<0.05; **P<0.01.
