特应性皮炎(AD)的特征是过敏性皮肤炎症。AD的一个标志是皮肤干燥瘙痒,至少部分原因是皮肤基因缺陷,这些基因对维持皮肤屏障功能很重要。AD的发病机制仍不完全清楚。自从将Nc/Nga小鼠描述为自发发生的AD模型以来,已经开发了许多AD小鼠模型。它们可以分为三组:1)通过表皮应用致敏剂诱导的模型; 2)过度表达或缺乏选择性分子的转基因小鼠; 3)自发发展AD样皮肤病变的小鼠。这些模型使我们对AD的发病机制有了更好的了解。本文综述了这些模型,并强调机械性皮肤损伤和皮肤屏障功能障碍在引发过敏性皮肤炎症中的作用。
Atopic Dermatitis (AD) is characterized by allergic skin inflammation. A hallmark of AD is a dry itchy skin, due at least in part, to defects in skin genes that are important for maintaning skin barrier function. The pathogenesis of AD remains incompletely understood. Since the description of the Nc/Nga mouse as a spontaneously occurring model of AD, a number of mouse models of AD have been developed. They can be categorized into three groups: 1) Models induced by epicutaneous application of sensitizers; 2) Transgenic mice that either over-express or lack selective molecules; 3) Mice that spontaneously develop AD-like skin lesions. These models have resulted in a better understanding of the pathogenesis of AD. This review discusses these models and emphasizes the role of mechanical skin injury and skin barrier dysfunction in eliciting allergic skin inflammation.
