We demonstrated that HP serum samples contain IgG against either Dsg1 or Dsg3 and that in most HP serum samples there were no antibodies directed against cell surface molecules other than Dsg1 or Dsg3. Direct immunofluorescence stainings revealed the deposition of IgG on keratinocyte cell surfaces in all samples. Pemphigus controlled by sulphapyridine. 1. However, others described it as a variant of PF10 or PV.11. Four HP serum samples showed slightly higher OD values compared with those of control serum samples (samples 5 and 6 for Dsg1 ELISA and samples 18 and 19 for Dsg3 ELISA). Reactivity of IgA-class antibodies was indicated with OD and compared with those of control serum samples. IMMUNOADSORPTION ASSAYS WITH rDsg1 AND rDsg3 BACULOPROTEINS, HP SERA DO NOT CONTAIN IgG AGAINST CELL SURFACE MOLECULES OTHER THAN Dsg1 OR Dsg3. 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. First, IgG fractions prepared from patients with PF and PV can induce blisters in skin organ culture and in neonatal mice.25-27 Second, removal of anti-Dsg1 or anti-Dsg3 autoantibodies from PF or PV sera, respectively, abolished the ability of the sera to induce blister formation in neonatal mice.18,19 Third, Dsg1 and Dsg3 are expressed in the epidermis, where blister formation occurs in PF and PV, respectively.21 At present, the distinct pathophysiological events responsible for these differences are unknown. The desmoglein plays an important part in the formation of desmosomes. 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.

In Pemphigus disease the blisters are formed intraepidermally whereas in Bullous autoimmune dermatoses they occur subepidermally. However, the meaning of reactivities against Dsg1 and Dsg3 was unclear because indirect immunofluorescence showed no staining on keratinocyte cell surfaces for IgA antibodies (data not shown). Dsg1 and Dsg3 are the major cell surface target molecules of HP, suggesting that most cases of HP are clinical variants of pemphigus foliaceus and that the rest might be variants of pemphigus vulgaris. Immunofluorescence staining of this serum showed a unique pattern with coarse dotlike staining along the cell-cell contact sites (data not shown), which favors the former possibility. Amagai
Some studies12-14 claimed that HP sera recognized the 160-kd Dsg1, and another15 claimed that HP serum recognized the 130-kd Dsg3. However, it can be speculated that the phenotype differences may be caused by differences of epitopes recognized by autoantibodies. The ELISA analysis demonstrated that of 20 HP serum samples, 16 had anti-Dsg1 IgG autoantibodies and 4 had anti-Dsg3 IgG autoantibodies. Scores on ELISA against Dsg1 and Dsg3 were obtained as previously reported with a slight modification. NNishikawa
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. et al.

B Production of epidermal acantholysis in normal human skin in vitro by the IgG fraction from pemphigus serum. Characterization of autoantibodies in pemphigus using antigen-specific enzyme-linked immunosorbent assays with baculovirus-expressed recombinant desmogleins. Desmoglein-1 is a calcium-binding transmembrane glycoprotein component of desmosomes in vertebrate epithelial cells. The absorbance was measured at 450 nm by an ELISA reader (Bio-Rad Laboratories, Hercules, Calif). A more intriguing question is why the clinical presentations of HP and classic pemphigus are so different despite the common presence of anti-Dsg1 or anti-Dsg3 IgG autoantibodies. The immunoreactivity against keratinocyte cell surfaces at 1:40 dilution of serum samples was judged for immunoadsorption assay. Serum samples were obtained from 20 patients with HP whose clinical manifestations resemble those of dermatitis herpetiformis in the form of the eruption, its symmetrical distribution, and pruritus. doi:10.1001/archderm.135.8.943.

Typically, annular erythematous plaques with vesicles and erosions on their margins were seen on the trunk and extremities (Figure 1). Dsg1 and Dsg3 are the major cell surface target molecules of HP, suggesting that most cases of HP are clinical variants of pemphigus foliaceus and that the rest might be variants of pemphigus vulgaris. Therefore, immunoblotting cannot detect autoantibodies against the conformationally sensitive epitope. The pemphigus diseases are caused by pathogenic autoantibodies against desmoglein 1 and desmoglein 3, two adhesion proteins found in keratinocytes. Desmoglein proteins are a type of cadherin, which is a transmembrane protein that binds with other cadherins to form junctions known as desmosomes between cells. Niizeki
