Seven protopanaxatriol-type ginsenosides and their aglycones including PPT, PT, -Re, -Rg (1), -F (1), -Rh (1), 20(R)-Rh (1) which are closely related in structure were studied for their effects on type 1 and type 2 cytokines production from murine splenocytes and their related mechanisms were examined. The results indicate that PPT, PT and ginsenoside-Re show hardly any or weak effects on concanavalin A (Con A)-induced production of IFN-gamma and IL-4. Ginsenoside-Rh (1) and 20(R)-Rh (1) induce a Con A-induced type 1 cytokine pattern by increasing the production of interleukin-12 (IL-12), the expression of IFN-gamma, T-bet and enhancing NF-kappaB DNA binding activity. In contrast ginsenosides-Rg (1) and -F (1) cause a Con A-induced type 2 cytokines response by increasing the expression of IL-4, GATA-3 and enhancing NF-kappaB DNA binding activity. Thus, these protopanaxatriol-type ginsenosides have different immunomodulatory effects, which might explain the complex immunomodulatory effect of Panax ginseng.
