Atopic dermatitis (AD) may show high, mild or low IgE production. Epidermal cell interleukin (IL)-18 production induced by Staphylococcus aureus protein A causes severe dermatitis, and serum IgE levels are gradually elevated later in AD model mice. The mechanism behind this dermatitis is independent of Th2 or IgE responses and is thus a model of low or mild IgE production AD.
colonisation may contribute to epidermal IL-18 production, especially in the AD group with relatively low IgE production.
This is the first report on the quantification of epidermal IL-18 production in patients with AD. Measurement of IL-18 in the horny layer is useful for evaluating the IL-18 production of epidermal keratinocytes as well as the effects of therapies in patients with AD.
