DS-Nh mice and WBN/Kob-Ht rats are spontaneous hairless mutant rodent strains. These animals develop spontaneous dermatitis under normal conditions. The non-hair Nh and Ht phenotypes are inherited in an autosomal dominant fashion, and the Nh mutation possesses a high potency for penetration. We previously reported that genes involved in dermatitis and(More)
We reported that the Gly573Ser substitution in transient receptor potential vanilloid 3 (TRPV3) led to increased ion channel activity in keratinocytes and caused spontaneous hairlessness in DS-Nh mice. DS-Nh mice also develop allergic and pruritic dermatitis. As the hairless and dermatitis phenotypes were both inherited in an autosomal dominant fashion and(More)
WBN/Kob-Ht rats (Ht-rats) raised under conventional conditions spontaneously developed dermatitis. In this study, we carried out histopathological analysis to elucidate the pathological features of the dermatitis in Ht-rats. We then tried to detect Staphylococcus species recovered from the skin lesions of Ht-rats. We also measured the serum levels of total(More)
DS-Nh mice raised under conventional conditions spontaneously develop dermatitis similar to human atopic dermatitis (AD), which is associated with staphylococcal infection. In the present study, we show that Staphylococcus aureus producing staphylococcus exotoxin C (SEC) was recovered from the culture of the skin lesions of DS-Nh mice with AD-like(More)
Itching is one of the major clinical symptoms in atopic dermatitis (AD) and complicates the management of this pathological condition. An animal model of AD-like pruritus would contribute to a better understanding of AD and could lead to the development of safe and effective antipruritic agents. DS non-hair (DS-Nh) mice raised under conventional conditions(More)
The herbal medicine "Sho-saiko-to (Xiao-Chai-Hu-Tang)" has been used in China for about 3000 years for the treatment of pyretic diseases. This medicine is now available as one of the prescribing drugs approved by the Ministry of Health and Welfare of Japan, and has also been widely used for patients with chronic viral liver disease as one of biological(More)
