| Description | We have examined the immunosuppressive effects of representative ginsenosides $(Rb_{1}$, $Rb_{2}$, Re and $Rg_{1}$) from Panax ginseng C. A. Meyer on CD4+ and CD8+ lymphocyte proliferation. Ginsenosides differentially modulated lymphocyte proliferation induced by concanavalin A (Con A), lipopolysaccharide (LPS), phytohemaglutinin (PHA) and interleukin-2 (IL-2). Thus, $Rb_{1}$ and Re significantly enhanced Con A-induced lymphocyte proliferation, whereas $Rg_{1}$ did not affect the proliferation. Interestingly, however, $Rb_{2}$ strongly blocked Con A, LPS and PHA-induced lymphocyte proliferation with the $IC_{50}$ values of 21.8, 29.0 and 24.0 μM, respectively. Moreover, $Rb_{2}$ inhibited Con A-stimulated IL-2 production with an $IC_{50}$ of 13.3 μM. In the IL-2-stimulated CD8+ T cell (CTLL-2) proliferation assay, Re and $Rg_{1}$ showed strong suppressive effects with $IC_{50}$ values of 57.5 and 64.7 μM, respectively. In contrast, neither $Rb_{1}$ nor $Rb_{2}$ did inhibit CTLL-2 cell proliferation at tested concentrations. These results suggest that ginsenosides from P. ginseng may modulate lymphocyte proliferation in a different manner. |
