Fig. 2.
WV vaccine stimulates the expression of MHC class II, CD54, CD80 and CD86 on DC. Immunofluorescence staining of purified DC incubated for 24 h with either WV (left panels) or v-SU (right panels) vaccine. The Figure shows one of 12 identical experiments. WV vaccine is more efficient in stimulating MHC class II, CD54, CD80 and CD86 expression than subunit vaccines. Similar results were obtained when c-SU vaccine was used instead of v-SU vaccine. c, Control; u, unstimulated control.
