Andrographolide Inhibits Inflammatory Cytokines Secretion in LPS-Stimulated RAW264.7 Cells through Suppression of NF-κB/MAPK Signaling Pathway

Figure 2

Effect of Andrographolide on morphologic changes and viability of RAW264.7 cells. (a) represents cells in control group; (b) represents cells treated by LPS; (c)–(e) represent cells treated with different concentration Andrographolide (6.25, 12.5, and 25 μg/ml) for 1 h and LPS for another 18 h, respectively; (f) represents the effect of Andrographolide on the cell viability of RAW264.7 cells in control, LPS, and Andrographolide treated groups. Results are representative of three (f) independent experiments.
