Anti-Inflammatory Effects of the Fraction from the Leaves of Pyrus pyrifolia on LPS-Stimulated THP-1 Cells

Figure 4

Effect of PP on the activation of MAPK in THP-1 cells. THP-1 cells were treated with PP (5–20 μg/mL) or DEX (20 μM) for 1 h and maintained with 0.1 μg/mL LPS for 30 min. The protein levels of total or phosphorylated (p) ERK, JNK, and 38 were measured by western blotting (a) and quantified (b–d). Data are expressed as the mean ± SD. versus negative control group; and versus LPS only group.
