Research Abstract

In this study, we characterized the effects of anti-mouse IL-17A, anti-mouse IL-12/ 23p40, and anti-mouse IL-23p19 Abs on the development of psoriasis-like lesions in K5. Stat3C transgenic mice. Treatment with anti-IL-12/ 23p40 or anti-IL-23p19 Abs greatly inhibited 12-O-tetradecanoylphorbol-13-acetate-induced epidermal hyperplasia in the ears of K5. Stat3C mice, whereas the inhibitory effect of an anti-IL-17A Ab was relatively less prominent. Taken together, this system provides a useful mouse model for psoriasis and demonstrates distinct roles for IL-23 and IL-17.
