SE derived from 0.141 g (low dose) or 0.562 g (high dose) of the leaves was administered orally for 15 days. High dose of SE suppressed ear swelling response induced by repeated 2,4-dinitrofluorobenzene (DNFB) paintings, and both low and high doses of SE reduced infiltration of immune cells into the ear dermis. Although the number of T cells, Treg, CD4+T cells and CD8+T cells in draining lymph nodes (dLNs) was not changed by SE, IFN- secretion from dLN induced by concanavalin A or 2,4-dinitrobenzenesulfonic acid was suppressed by a high dose of SE while IL-10 levels remained unchanged. These results suggest that SE suppresses allergic skin inflammation via reducing IFN- secreted from immune cells, especially T cells.", }
