摘要: 【摘要】 大疱性类天疱疮(BP)是最常见的自身免疫性表皮下水疱病,皮损真皮内有大量嗜酸性粒细胞(EOS)浸润。此外,在BP患者的水疱和外周血中,也发现有大量EOS及其活化的细胞因子和趋化因子,而且EOS被证实可导致真表皮分离。BP 患者的血清及疱液中白细胞介素 5 水平明显增高,该因子由 Th2 细胞及 EOS 分泌,具有调节 EOS 分化、活化和存活的作用 。以上证据均表明 EOS 与 BP 发病有一定的相关性。针对EOS及其细胞因子的研究,将开启BP靶向治疗的新领域。

Abstract: 【Abstract】 Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering skin disease, and a large number of eosinophils (EOS) obviously infiltrate the dermis of BP lesions. Additionally, EOS and their activated cytokines and chemokines are abundantly present in blisters and peripheral blood of BP patients. It is also proved that EOS can induce the dermal-epidermal separation. The level of interleukin (IL)-5 is markedly increased in the sera and blister fluids of BP patients, and IL-5 secreted by Th2 cells and EOS can regulate the differentiation, activation and survival of EOS. All the above evidence indicates that EOS are associated with the occurrence of BP. Researches on EOS and their cytokines will develop a new field of targeted therapy for BP.
