a, b Mice (N = 6/group) were immunized with NY-ESO-1 plus various adjuvants on days 0, 14, and 28. The levels of IgG (a), IgG1 and IgG2c (b) specific for NY-ESO-1 were detected by ELISA one week after the third immunization. Bars represent median. c, d The frequencies of IFN-γ-secreting CD4+ and CD8+ T cells were examined by intracellular IFN-γ staining (N = 3/group). e, f The average number of IL-4/IFN-γ-secreting splenocytes was calculated (N = 3/group). Bars represent means and SEM. *P < 0.05, **P < 0.01, ***P < 0.001.
