研究显示，2型炎症及其相关细胞因子白细胞介素4、13等在特应性皮炎（AD）中起关键作用。Th2细胞及2型细胞因子是2型炎症反应的核心驱动因素，主要通过3条路径参与AD发病：加重皮肤屏障缺陷；激活和强化瘙痒反应；调节性T细胞（Treg）病理性重编程为Th2样Treg细胞，从而放大2型炎症反应。本综述探讨2型炎症与AD的关系，希望有助于优化治疗方案，为AD患者提供新的治疗选择。“,”Studies have shown that the type 2 inflammatory response and related cytokines such as interleukin-4 and -13, play a key role in atopic dermatitis (AD) . Th2 cells and type 2 cytokines are the core factors in the type 2 inflammatory response, which is mainly involved in the pathogenesis of AD through 3 pathways: aggravating skin barrier defects; activating and strengthening the itching response; pathologically reprograming regulatory T cells into Th2-like regulatory T cells to amplify the type 2 inflammatory response. This review explores the relationship between the type 2 inflammatory response and AD, aiming to help optimize treatment regimens and provide new treatment options for patients with AD.
