Desmoglein-3

In Vitro Pathogenicity Assay for Anti-desmoglein Autoantibodies in Pemphigus

Patients with pemphigus have circulating anti-desmoglein (Dsg) 1 and/or Dsg3 autoantibodies that induce blister formation on the skin and mucous membrane. We describe here two assays that measure the pathogenic strength of autoantibodies

RNA Interference in Keratinocytes and an Organotypic Model of Human Epidermis

, namely desmoglein 1, in primary human epidermal keratinocytes maintained as submerged cultures or three-dimensional organotypic raft cultures. As a complement to epidermal-specific gene targeting strategies in mice, these technical approaches permit relatively rapid

完全桥粒(desmosome)

蛋白(desmoglein)和桥粒芯胶粘蛋白(desmocollin)。桥粒连接的细胞质膜的内表面有一致密的细胞质斑,作为锚定细胞骨架中间纤维的位点,锚定是通过细胞质斑中的桥粒斑蛋白(desmoplakin)介导的, 桥粒斑蛋白也属钙粘着蛋白。网状的中间纤维网络不仅提供了将周围细胞连成一体的结构组成,同时还增加了细胞的机械强度。
