Figure 1. The expression of IL-25 in human skin.
(a) Representative paraffin embedded skin biopsies from normal subjects (n=10) and patients with ADEH− (n=18), ADEH+ (n=7) and psoriasis (n=9) stained for IL-25 (red) are shown. Wheat germ agglutinin-conjugated fluorescein isothiocyanate (green) stained the cytoskeleton. Images were collected at x 400 magnification. Arrows point to IL-25 expression. Bar=50 μm. (b) The mean fluorescent intensity of IL-25 is shown in the epidermis of each biopsy. *P < 0.05, **P < 0.01.
