特应性皮炎的部位异质性

特应性皮炎（AD）是一种高度异质性皮肤病，以往在年龄、严重度、炎症模式等方面的分型较为成熟，而对不同部位皮损特征的关注较少。最近发现不同部位AD对度普利尤单抗治疗的应答存在差异，表明不同部位皮损可能具有不同的炎症模式。因此本文提出AD部位异质性的概念，结合生理条件下不同部位皮肤的细胞生物学和微生态特点，分析不同部位AD...

Heterogeneity across skin sites in atopic dermatitis

【Abstract】 Atopic dermatitis （AD） is a highly heterogeneous skin disease. The subtypes of AD classified by age, severity and inflammatory patterns have been widely accepted previously; however, the heterogeneity in skin lesions across different body sites has been rarely addressed. Most recently, it has been found that the efficacy of dupilumab varies across different body sites, suggesting different patterns of inflammation in skin lesions at different body sites. Thus, this article proposes the concept of heterogeneity across body sites in AD, summarizes cell biological features and microbiome at different skin sites under physiological conditions, analyzes clinical manifestations of, multi-omic study results from and treatment response of AD at different sites, and discusses pathogenesis of AD, providing a basis for individualized therapy of AD.
