Research Abstract

TNF-alpha and IL-17A significantly up-regulated the expression of LEKTI, SLPI, and elafin in cultured normal human epidermal keratinocytes. Immunohistochemical analysis confirmed LEKTI expression in atopic dermatitis lesions was almost same as in normal skin, but it was significantly higher in psoriasis lesions than in atopic dermatitis lesions.
Topical application of serine protease inhibitors such as benzamidine did not significantly improve the skin lesions in a mouse model of Th2-dependent dermatitis.
