Notoginseng inhibits the expression of costimulatory molecules on DC2.4 cells following stimulation with TLR ligands. Cells were unstimulated (dashed line) or stimulated (black line) with LPS, CpG or poly(I:C) and concomitantly treated with 50 µg/ml notoginseng (gray histogram) for 24 hours. Representative histograms demonstrating the cell surface expression of CD40 (A) and CD86 (B) on activated DC2.4 cells were determined by FACS analysis. Data are representative of three independent experiments, each consisting of a minimum of three samples per treatment group.
