Epiisopiloturine, an Alkaloid from Pilocarpus microphyllus, Attenuates LPS-Induced Neuroinflammation by Interfering in the TLR4/NF-κB-MAPK Signaling Pathway in Microglial Cells

Figure 4

Effect of EPI in LPS-induced iNOS expression in microglia. BV-2 cells were pretreated with EPI (25 μg/mL) for 1 h before the addition of LPS (0.5 μg/mL). Results are expressed as of iNOS/β-actin band intensity. # vs. vehicle/RPMI; vs. LPS group (—two-way ANOVA and Bonferroni test), .
