Induction of effective and increased levels of antibody production may be major points in vaccine development. This is especially the case when the antigenic sources are carbohydrates. Thus, in our Lab various types of formulations such as liposomal and conjugate vaccines have been researched. However, the fastidious formulation process and high costs are a problem. For this reason, there is currently a focus on utilizing immunoadjuvants. In this present study, we tested whether ginsenosides Re (a panaxdiol) and Rg1 (a panaxtriol) from Panax ginseng have immunoadjuvant activity against the cell wall of Candida albicans (CACW). The resulting data showed that Rd and Rg1 caused LPS-treated B lymphocytes to be proliferative. Rd had greater proliferation activity than that of Rg1. In the murine model of antibody production, CACW combined with Rd [CACW/Rd/IFA] or Rg1 [CACW/Rg1/IFA] increased the production of antibodies specific to C. albicans when compared to the antibody production by [CACW/IFA]-induction, which was used as a negative control (P<0.05). In the case of [CFA/Rd/IFA], the antibody production was almost twice as that of the CFA. In addition, formulations containing either had a prolonged antibody inducing activity as compared to the CFA formula. In conclusion, Rd and Rg1 have an immunologic activity, and yet Rd can be a better candidate than Rg1 for a new immunoadjuvant.
