Pemphigus IgG Causes Skin Splitting in the Presence of Both Desmoglein 1 and Desmoglein 3

Pemphigus foliaceus IgG causes dissociation of desmoglein 1-containing junctions without blocking desmoglein 1 transinteraction.

Autoantibodies against the epidermal desmosomal cadherins desmoglein 1 (Dsg1) and Dsg3 have been shown to cause severe to lethal skin blistering clinically defined as pemphigus foliaceus (PF) and pemphigus vulgaris (PV). It is unknown whether antibody-induced dissociation of keratinocytes is caused by direct inhibition of Dsg1 transinteraction or by secondary cellular responses. Here we show in...

The effect of aspirin on haemostatic activity in the treatment of chronic venous leg ulceration. Pemphigus foliaceous (PF) is generally a benign autoim-mune blistering disease, but in some patients lesions are severe with serious implic...

Desmoglein 3-Mediated Transinteraction Pemphigus Vulgaris IgG Directly Inhibit

Desmoglein 1 and desmoglein 3 are the target autoantigens in herpetiform pemphigus.

OBJECTIVE To determine the cell surface autoimmune target of herpetiform pemphigus (HP). DESIGN Serum samples of HP were examined by immunoblot studies with human epidermal extracts, enzyme-linked immunosorbent assay with baculovirus-expressed recombinant desmoglein (rDsg) 1 and rDsg3, and immunoadsorption assay with rDsg. PATIENTS Twenty serum samples were obtained from patients with HP wh...

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...
