Abstract

Epicutaneously administered chemical antigens like 2,4-dinitrofluorobenzene (DNFB), evoke an atopic dermatitis (AD)-like dermatitis reaction in NC/Nga mice under specific pathogen free (SPF) conditions. Astragalus membranaceus (AM), is a popular herbal medicine used to treat allergic diseases in East Asia. In the present study, we examined whether AM suppress AD-like skin lesions in NC/Nga mice treated with DNFB under SPF conditions. Oral administration of AM to DNFB-treated NC/Nga mice was found to inhibit ear thickness increases and the skin lesions induced by DNFB. Moreover, IFN-γ production by CD4 + T cells from the lymph nodes of DNFB-treated NC/Nga mice was significantly inhibited by AM treatment, although levels of IL-4 and total IgE in serum were not. Study findings suggest that AM may suppress the development of AD-like dermatitis in DNFB-treated NC/Nga mice by reducing IFN-γ production.
