Synergy among non-desmoglein antibodies contributes to the immunopathology of desmoglein antibody–negative pemphigus vulgaris

IgA pemphigus showing IgA antibodies to desmoglein 1 and 3

BACKGROUND IgA pemphigus is a rare autoimmune vesiculo-pustular skin disease. Only approximately 70 cases have been reported to date. We report a case of IgA pemphigus with IgA antibodies to desmoglein 1 (Dsg1) and desmoglein 3 (Dsg3). CASE REPORT We report the case of an 60-year-old man with intraepidermal neutrophilic IgA pemphigus with IgA antibodies to Dsg1 and Dsg3. Histologic examinatio...

Desmoglein 3-ELISA: a pemphigus vulgaris-specific diagnostic tool.

BACKGROUND Pemphigus vulgaris (PV) is an autoimmune-blistering disease of the skin and mucous membranes caused by autoantibodies against desmoglein 3 (Dsg3), an epidermal desmosomal adhesion protein of the cadherin family. Cloning of the Dsg3 gene and expression of the protein in a native conformation enabled the recent development of a specific and sensitive enzyme-linked immunosorbent assay (...

Desmoglein 3-Mediated Transinteraction Pemphigus Vulgaris IgG Directly Inhibit

A comparison of anti-desmoglein antibodies and indirect immunofluorescence in the serodiagnosis of pemphigus vulgaris.

BACKGROUND Indirect immunofluorescence (IIF) is the standard method for the detection of pemphigus autoantibodies. Commercially available enzyme-linked immunosorbent assays (ELISAs) have recently become available to measure serum antibodies (Abs) against desmoglein1 (Dsg1) and desmoglein3 (Dsg3). It has been suggested that patients with mucosal-dominant pemphigus vulgaris (PV) have serum Abs ag...

Desmoglein ELISA in the diagnosis of pemphigus and its correlation with the severity of pemphigus vulgaris.

Anti-desmoglein 3 and 1 autoantibodies are involved in the pathogenesis of pemphigus diseases. Our objective was to assess the value of ELISA in the diagnosis of pemphigus and its correlation with the severity of pemphigus vulgaris. Based on clinical presentation and histopathologic confirmation for the diagnosis of the pemphigus, 38 patients took part in the study. Sera of the patients were te...
