Abstract

Blister development in bullous pemphigoid (BP) results from destruction of hemidesmosomes and basement membrane components within the dermoepidermal junction by autoantibodies. Adhesion molecules can take part in pathogenesis of this disease. The aim of the study was to determine the localization and expression of L- and E-selectins and beta1, beta3, and beta4 integrins by immunohistochemistry in skin lesions of 21 patients with BP, compared with 10 healthy subjects. Expression of L and E selectins and beta1, beta3 integrins was detected mainly in basal keratinocytes and in inflammatory infiltrates in the dermis, expression of beta4 integrin was irregular and was detected mainly in dermal part of the blister, while in the control group only weak and single expression of the examined molecules was detected in basal keratinocytes and endothelium cells. The obtained results reveal the important role of selected selectins and integrins in development of skin lesions in BP.

摘要

大疱性类天疱疮(BP)中的水疱形成是由自身抗体破坏真皮表皮连接处的半桥粒和基底膜成分所致。黏附分子可参与该疾病的发病机制。本研究的目的是通过免疫组织化学法确定21例BP患者皮肤病变中L-选择素、E-选择素以及β1、β3和β4整合素的定位和表达,并与10名健康受试者进行比较。L-选择素、E-选择素以及β1、β3整合素的表达主要在基底角质形成细胞和真皮中的炎性浸润中检测到,β4整合素的表达不规则,主要在水疱的真皮部分检测到,而在对照组中,仅在基底角质形成细胞和内皮细胞中检测到所检测分子的微弱和单一表达。所得结果揭示了所选选择素和整合素在BP皮肤病变发展中的重要作用。
