Abstract

MCS-18, a natural product isolated from Helleborus purpurascens has been shown to have several beneficial effects in inflammatory and autoimmune disorders. However, very little is known regarding the immuno-modulatory capacity of MCS-18 in respect to murine bone marrow-derived dendritic cells (BM-DC) and B-cells. Thus, in the present study we examined the effect of MCS-18 on murine BM-DC and B-cells. Interestingly MCS-18 inhibited the expression of important DC-specific molecules and lead to an impaired T-cell stimulation capacity. In addition, MCS-18 also reduced B-cell proliferation and immunoglobulin production.
