Anti-Inflammatory Effects of the Fraction from the Leaves of Pyrus pyrifolia on LPS-Stimulated THP-1 Cells
Figure 2
Effects of PP on inhibition of proinflammatory molecules in LPS-stimulated THP-1 cells. THP-1 cells were pretreated with PP (5–20 μg/mL) or DEX (20 μM) for 1 h and maintained with 0.1 μg/mL LPS for 6 h. The expressions of MCP-1 (a), TNF-α (b), IL-8 (c), and IL-6 (d) were measured by ELISA. After treatment for 24 h with (e) or without LPS (f), cell viability was determined. Data are expressed as the mean ± SD. versus negative control group; and versus LPS only group.
