TFDiaz 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.  KShafran  SChorzelski It consists of erythematous papules, urticarial-like plaques, or vesicles. Staphylococcal exfoliative toxins act as serine proteases with extremely focused molecular specificity to cleave mouse and human desmoglein 1 (Dsg1) once after glutamic acid residue 381 between extracellular domains 3 and 4.  VPOkla  RHBurton  LA Pemphigus herpetiformis is a rare clinical expression of nonendemic pemphigus foliaceus, fogo selvagem, and pemphigus vulgaris. Immunoadsorption assays with recombinant desmoglein (rDsg) 1 and rDsg3 baculoproteins. 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. Briefly, 201-fold diluted serum samples underwent reaction for 1 hour, and then peroxidase-conjugated antihuman IgG antibodies (Medical and Biological Laboratories, Nagoya, Japan) were used as a second antibody. 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. No anticoagulants, or preservatives should be added. The immunoreactivity against keratinocyte cell surfaces at 1:40 dilution of serum samples was judged for immunoadsorption assay.

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. Schiltz Patients  When the autoantibodies bind to the desmoglein 1 and 3 … No serum samples reacted with both.  C A case of herpetiform pemphigus. Autoantibodies in PF and PV recognize functionally important regions on Dsg and inhibit their adhesive function, leading to the loss of cell adhesion. Amagai M, Tsunoda K, Zillikens D, et al: The clinical phenotype of pemphigus is defined by the anti-desmoglein autoantibody profile. 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. Ingber Classic pemphigus consists of 2 major subtypes—pemphigus foliaceus (PF) and pemphigus vulgaris (PV). Amagai Most HP serum samples contained the autoantibodies against Dsg1.  VStanley The Nikolsky sign was negative. Ishii Thiopronine-induced herpetiform pemphigus: report of a case studied by immunoelectron microscopy and immunoblot analysis.
