The present invention provides methods which use induction phenomenon of production of interleukin 18 (IL-18) from keratinocyte (KC), and their usages. The methods are preferably applicable for understanding of pathogenic mechanisms of atopic dermatitis (AD) and AD-like symptoms, and for development of therapeutic drugs for AD and AD-like symptoms. For example, by applying, on skin of mice or the like, protein A (SpA) derived from, or transplanting, on mice, a skin graft which has developed an inflammatory skin disease like AD, it is possible to reproduce elevation of IgE to high level in serum, which elevation is generated in an AD-like lesion. As a result, it is possible, for example, to screen for an inhibitor which inhibits induction of production of IL-18 from KC.

Inhibitor screening method and atopic dermatitis like symptom inducing method which utilizes induction of production of interleukin 18 by keratinocyte and utilization of same
