ASI decreases the production of TNF-α, IL-1β and IL-6 in LPS-treated CCD-18Co cells in vitro. CCD-18Co cells were pretreated with ASI (0, 10, or 50 µM) for 24 h, following treated LPS (1 µg/ml) for 2 h. (A) The viability of CCD-18Co cells was examined using a CCK-8 assay. (B) The level of TNF-α in the culture media was measured with ELISA. (C) The level of IL-1β in the culture media was measured with ELISA. (D) The level of IL-6 in the culture media was measured. **P<0.01 vs. the control group. #P<0.05 and ##P<0.01 vs. the LPS-treated group. ASI, astragaloside IV; TNF-α, tumor necrosis factor-α; IL, interleukin; LPS, lipopolysaccharide.
