Meoruh wine suppresses mast cell-mediated allergic inflammation

Abstract

In this study, we investigated the effect of the Meoruh wine (MW), a Korean traditional wine made by the fruits of Vitis amurensis Rupr. (Vitaceae) on the mast cell-mediated allergic inflammation and studied the possible mechanism of action. Mast cell-mediated allergic disease is involved in many diseases such as anaphylaxis, rhinitis, asthma, and atopic dermatitis. MW inhibited compound 48/80-induced systemic anaphylaxis and serum histamine release in a dose-dependent manner in mice. MW decreased immunoglobulin E-mediated local allergic reactions, passive cutaneous anaphylaxis. MW dose-dependently reduced histamine release from human mast cells activated by phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI). The inhibitory effect of MW on histamine release was mediated by suppression of intracellular calcium. In addition, MW attenuated the PMACI-stimulated expression of pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin-1β (IL-1β), IL-6, and IL-8 in human mast cells. The inhibitory effect of MW on these pro-inflammatory cytokines was nuclear factor (NF)-κB dependent. Our findings provide evidence that MW inhibits mast cell-derived allergic inflammatory reactions and involvement of calcium, pro-inflammatory cytokines and NF-κB in these effects.
