Autoimmune blistering diseases are examples of autoantibody-mediated, organ-specific autoimmune disorders. Based on a genetic susceptibility, such as a strong HLA-class II association, as yet unknown triggering factors induce the formation of circulating and tissue-bound autoantibodies that are mainly directed against adhesion structures of the skin and mucous membranes. Compared with other autoimmune diseases, especially systemic disorders, the pathogenicity of autoimmune blistering diseases is relatively well described. Several animal models of autoimmune blistering diseases have been established that helped to uncover the immunological and molecular mechanisms underlying the blistering phenotypes. Each in vivo model focuses on specific aspects of the autoimmune cascade, from loss of immunological tolerance on the level of T and B cells to the pathogenic effects of autoantibodies upon binding to their target autoantigen. We discuss current mouse models of autoimmune blistering diseases, including models of pemphigus vulgaris, bullous pemphigoid, epidermolysis bullosa acquisita, and dermatitis herpetiformis.

自身免疫性水疱病是自身抗体介导的器官特异性自身免疫性疾病的例子。基于遗传易感性,例如强烈的HLA-II类关联,目前尚未发现的触发因素诱导循环和组织结合的自身抗体的形成,这些抗体主要针对皮肤和粘膜的黏附结构。与其他自身免疫性疾病,尤其是全身性疾病相比,自身免疫性水疱病的致病性相对较好地描述。已经建立了几种自身免疫性水疱疾病的动物模型,这些模型有助于揭示水疱表型的免疫学和分子机制。每个体内模型都专注于自身免疫级联反应的特定方面,从T细胞和B细胞水平的免疫耐受性丧失到自身抗体与靶自身抗原结合后的致病作用。我们讨论了自身免疫性水疱疾病的当前小鼠模型,包括寻常性天疱疮,大疱性天疱疮,表皮松解性大疱性水疱病和疱疹样皮炎的模型。
