Imperatorin Suppresses Anaphylactic Reaction and IgE-Mediated Allergic Responses by Inhibiting Multiple Steps of FceRI Signaling in Mast Cells: IMP Alleviates Allergic Responses in PCA

Figure 7

Effects of IMP on activation of Nrf2 and HO-1 signaling pathways. RBL-2H3 cells were stimulated with 10 μg/ml anti-DNP IgE for 6 h and challenged with 100 ng/ml DNP-HAS, in the absence or presence of IMP (10, 20, and 40 μM, respectively). (a-b) Nrf2 (a) and HO-1 (b) levels were detected by Western blot analysis. Compared with the Con group, P<0.05, ∗∗P<0.01; compared with the IgE+Ag group, #P<0.05, ##P<0.01.
