Magnolin Inhibits IgE/Ag-induced Allergy in Vivo and in Vitro.
International immunopharmacology(2019)
摘要
Mast cells (MCs) play critical roles in allergic reactions and modulating the activation of MCs could be an effective strategy to treat allergic diseases, which cause a rapidly increasing threat to the public health. Herein, we described that Magnolin, a major component from Flos magnoliae could inhibit IgE-dependent MCs activation. We found Magnolin inhibited IgE/Ag-induced calcium mobilization, degranulation, and cytokines release in LAD2 cells. Magnolin was also found to attenuate IgE/Ag-induced mice paw swelling in a dose-dependent manner. Further mechanistic studies suggested a possible anti-allergic and anti-inflammatory effects of Magnolin in IgE/Ag-induced anaphylactic reactions. Thereby, Magnolin could be a potential therapeutic agent for preventing mast cell-related immediate and delayed allergic diseases.
