Effects of DPL extract on LPS-induced pro-inflammatory cytokine production in RAW264.7 cells. RAW264.7 cells were treated with LPS (1 µg/ml) in the presence or absence of DPL extract at the indicated concentrations for 24 h. (A) TNF-α and (B) IL-6 in the culture supernatant were measured by ELISA. Each bar represents the mean ± standard deviation calculated from three independent experiments. *P<0.05 vs. LPS only treatment. DPL, Dendropanax morbifera leaf; LPS, lipopolysaccharide; TNF-α, tumor necrosis factor-α; IL, interleukin.
