Atopic dermatitis-like pruritic skin inflammation caused by feeding a special diet to HR-1 hairless mice.
Dry skin/barrier dysfunction is considered to be one of the characteristic features of atopic dermatitis (AD). When HR-1 hairless mice are fed a special diet, HR-AD, dry red skin is induced. We examined whether HR-AD-fed mouse could be used as a model for AD by showing itch-associated scratching behaviour and by analysing the immunological change. ⋯ The skin barrier dysfunction in HR-AD-fed mice is closely associated with the development of AD-like pruritus. Changes in the immunological parameters observed may be the consequence of skin barrier dysfunction. Our findings suggest that HR-AD-fed mouse could be used as a dry skin-based experimental model for AD.
