Resveratrol Inhibits Allergic Reactions in Mice

Editor's Note: Resveratrol, a compound found in grapes and other plants, has been widely studied for its therapeutic effects, including the reduction of oxidative stress, weight loss,and anti-tumor  as well as anti-inflammatory and anti-microbial effects. 

Resveratrol Inhibits IgE-Mediated Basophilic Mast Cell Degranulation and Passive Cutaneous Anaphylaxis in Mice

By Seon-Young Han et al.

Abstract

Resveratrol is a phytoalexin abundantly found in red grape skin and is effective in antitumor and antiinflammation associated with immune responses. This study investigated whether resveratrol suppressed immunoglobulin (Ig)E-mediated allergic responses and passive cutaneous anaphylaxis (PCA) in rat RBL-2H3 mast cells and in BALB/c mice.

The release of B-hexosaminidase and histamine was enhanced in mast cells sensitized with anti-dinitrophenyl (DNP)-IgE and subsequently stimulated by DNP-human serum albumin (HSA), indicative of mast cell degranulation. When mast cells were pretreated with nontoxic resveratrol at 1–25 umol/L, such induction was dose dependently diminished. Spleen tyrosine kinase (Syk) and phospholipase Cgamma (PLCgamma) of sensitized mast cells were activated by stimulation with DNP-HSA antigen, which was dampened by > or equal to 5 umol/L resveratrol. The phosphorylation of protein kinase C (PKC)u and PKCtheta was attenuated by administering resveratrol to DNP-HSA–exposed mast cells, whereas quiescent PKCzeta/lambda in sensitized cells was dose-dependently activated by resveratrol. Male BALB/c mice were sensitized for 24 h with DNP-IgE and orally administered with resveratrol 1 h before the DNP-HSA challenge.

The histamine concentration was enhanced in sensitized mice challenged to DNP-HSA, which was reversed by administration of 10 mg/kg resveratrol. Additionally, it encumbered the tissue activation of Syk, PLCgamma, and PKCu in antigen-exposed mice. Resveratrol decreased IgE-mediated PCA and alleviated allergic edema of mouse ear and dorsal skin. Mast cell degranulation and allergic inflammation, accompanying the induction of monocyte chemotactic protein-1 and macrophage inflammatory protein-2, were inhibited by supplementing resveratrol to antigen-challenged mice.

Resveratrol inhibited mast cell-derived, immediate-type allergic reactions, and these responses of resveratrol suggest possible therapeutic strategies in preventing allergic inflammatory diseases.
