title: Anti-allergic effects of Artemisia iwayomogi on mast cell-mediated allergy model.
abstract: The discovery of drugs for the treatment of allergic disease is an important subject in human health. The Artemisia iwayomogi (Compositae) (AIE) has been used as a traditional medicine in Korea and is known to have an anti-inflammatory effect. However, its specific mechanism of action is still unknown. In this report, we investigated the effect of AIE on the mast cell-mediated allergy model and studied the possible mechanism of action. AIE inhibited compound 48/80-induced systemic reactions and plasma histamine release in mice. AIE decreased immunoglobulin E (IgE)-mediated local allergic reaction, passive cutaneous anaphylaxis (PCA) reaction. AIE dose dependently attenuated histamine release from rat peritoneal mast cells activated by compound 48/80 or IgE. AIE decreased the compound 48/80-induced intracellular Ca(2+). Furthermore, AIE decreased the phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-stimulated tumor necrosis factor-alpha and interleukin-6 gene expression and production in human mast cells. The inhibitory effect of AIE on the proinflammatory cytokine was p38 mitogen-activated protein kinase (MAPK) and nuclear factor-kappaB (NF-kappaB) dependent. AIE attenuated PMA plus A23187-induced degradation of IkappaBalpha and nuclear translocation of NF-kappaB and specifically blocked activation of p38 MAPK but not that of c-jun N-terminal kinase and extracellular signal-regulated kinase. Our findings provide evidence that AIE inhibits mast cell-derived immediate-type allergic reactions and involvement of intracellular Ca(2+), proinflammatory cytokines, p38 MAPK, and NF-kappaB in these effects.
