Multiplexed autoantigen microarrays identify HLA as a key driver of anti-desmoglein and -non-desmoglein reactivities in pemphigus.
Patients with pemphigus vulgaris (PV) harbor antibodies reactive against self-antigens expressed at the surface of keratinocytes, primarily desmoglein (Dsg) 3 and, to a lesser extent, Dsg1. Conventionally, only antibodies targeting these molecules have been thought to contribute to disease pathogenesis. This notion has been challenged by a growing pool of evidence that suggests that antibodies ...
متن کاملA simple epithelial cell line (MDCK) shows heterogeneity of desmoglein isoforms, one resembling pemphigus vulgaris antigen.
The epidermal blistering disease, pemphigus vulgaris (PV), is caused by circulating autoantibodies that react with a desmosomal glycoprotein desmoglein (Dsg3). This antigen is expressed only in stratified epithelial tissues. Here we show that the simple epithelial canine kidney cell line, MDCK, expresses at least two desmoglein isoforms recognised by different monoclonal antibodies. One of thes...
متن کاملPemphigus vulgaris antigen, a desmoglein type of cadherin, is localized within keratinocyte desmosomes
Pemphigus vulgaris antigen (PVA) is a member of the desmoglein subfamily of cadherin cell adhesion molecules. Because autoantibodies in this disease cause blisters due to loss of epidermal cell adhesion, and because desmoglein is found in the desmosome cell adhesion junction, we wanted to determine if PVA is also found in desmosomes. By immunofluorescence, PV IgG bound, in a dotted pattern, to ...
متن کاملDesmoglein 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...
متن کاملRadioiodine as a possible triggering agent for pemphigus foliaceus
Pemphigus foliaceus (PF) is an autoimmune blistering disease presenting in endemic and sporadic forms. The typical presentation is recurrent shallow erosions in a seborrheic distribution. PF has also been found in association with autoimmune diseases such as autoimmune thyroid disease (e.g. toxic nodular goiter and Hashimoto’s thyroiditis). In some patients, PF appears to be triggered by radioi...
