“…A topic dermatitis (AD) is a chronic relapsing skin disease characterized by eczematous skin lesions typically distributed at the predilection sites with lichenification, pruritic excoriations, and susceptibility to cutaneous infections associated with pruritic dry skin changes observable even in non‐lesional skin (1–3). In recent years, the number of AD patients has greatly increased in Japan as well as in other industrialized countries (4–7). To investigate the mechanisms of AD pathogenesis, different mouse models have been developed, e.g., Balb/C mouse repeatedly treated with 2,4,6‐trinitro‐1‐chrolobenzene (TNCB) (8, 9) and the NC/Nga mouse (10, 11).…”
