Regarding IgA-class anti-Dsg1 and anti-Dsg3 antibodies, we analyzed these serum samples by ELISA. RHBurton
No serum samples reacted with both. Therefore, immunoblotting cannot detect autoantibodies against the conformationally sensitive epitope. Desmoglein 3 is most highly expressed in the basal layers of the epidermis, while desmoglein 1 is expressed in the differentiated suprabasal layers (Kottke et al., 2006). TShiotani
The pemphigus diseases are caused by pathogenic autoantibodies against desmoglein 1 and desmoglein 3, two adhesion proteins found in keratinocytes. MMKonohana

Methods: Seventy-eight cases of head and neck squamous cell carcinoma were immunohistochemically stained for desmoglein 1, desmoglein 2, desmoglein 3, p53, bcl-2, vimentin, cyclin D1, p16, p21, p27, E-cadherin, and E2F-1 … JR Pemphigus vulgaris antigen (desmoglein 3) is localized in the lower epidermis, the site of blister formation in patients.

Furthermore, in 19 of 20 HP serum samples, immunoreactivity against keratinocyte cell surfaces was completely removed by preincubation with rDsg1 and rDsg3 as shown by indirect immunofluorescence, excluding a possibility that these HP sera contain autoantibodies against other cell surface molecules. Hashimoto
In contrast, the ELISA system with rDsg1 and rDsg3 expressed by baculovirus detects autoantibodies against conformational epitopes on Dsg1 or Dsg3. In contrast, autoantibodies in HP may recognize a functionally less important part of the molecule and therefore are not able to induce loss of cell adhesion. TGreen
Five serum samples recognized a 160-kd polypeptide, which comigrated with the band recognized by PF sera. N

The desmoglein plays an important part in the formation of desmosomes. A herpetiform pemphigus serum sample (sample 2 in Table 1) was incubated with control solution without baculoproteins (top) or a mixture of rDsg1 and rDsg3 baculoproteins (bottom) and subjected to immunofluorescence staining on healthy human skin. FJGrover
A single PF serum sample and PV serum sample were selected as positive control serum samples for Dsg1 and Dsg3 ELISA, respectively. Alternatively, this sample may have autoantibodies against the cytoplasmic portion of Dsg1 or Dsg3 because the recombinant proteins used for ELISA and immunoadsorption assay represent only the extracellular domains.

T Mixed bullous disease. DESMOGLEIN (DSG) 1 AND 3 ANTIBODY Bullous autoimmune dermatoses belong to the organ specific autoimmune diseases. Herpetiform pemphigus showing reactivity with pemphigus vulgaris antigen (desmoglein 3). The purpose of this study was to characterize the autoantigen of HP. From: Current Topics in … Herpetiform pemphigus is a unique form of pemphigus that clinically resembles dermatitis herpetiformis—an IgA-mediated disease—and immunologically has a feature of pemphigus—circulating and in vivo bound IgG autoantibodies against keratinocyte cell surfaces.
