Regulatory effects of cytokine production in atopic allergic reaction by Gammi-danguieumja

Gammi-danguieumja (GD) is clinically used in South Korea for treating atopic dermatitis. However, its effects in experimental models remain unknown. We investigated a possible effect of GD on cytokines production using human T cell line (MOLT-4) or human mast cell line. As a result, GD (0.01 mg/mL)-containing medium in stimulated culture supernatants increased IL-2 and IFN-γ, and decreased IL-4 secretion in MOLT-4. GD (0.01-1 mg/mL)-containing medium in stimulated culture supernatants dose-dependently and significantly decreased IL-8, IL-13, and tumor necrosis factor-alpha secretion on the phorbol 12-myristate 13-acetate and A23187-stimulated HMC-1. In addition, GD inhibited histamine release from activated mast cells. These results suggest that GD contributes to the regulation of atopic allergic reactions.
