This particular serum sample may contain autoantibodies against molecules other than Dsg3 in addition to antibodies against Dsg3. Based on its clinical features, some researchers8,9 reported the disease as a distinct entity and consider it to be different from classic pemphigus because of its clinical peculiarity and benign course.  MMita Hashimoto Accessibility Statement, Immunologic Characteristics of Sera of Patients With Herpetiform Pemphigus*. anti-desmoglein 3; anti-desmoglein 1; Histology acantholysis . Desmoglein-1 is a calcium-binding transmembrane glycoprotein component of desmosomes in vertebrate epithelial cells. 2007 Nov;21(10):1319-24.  KMWebber  E This antibody was isolated as a human IgG1 from a patient with … Classic pemphigus consists of 2 major subtypes—pemphigus foliaceus (PF) and pemphigus vulgaris (PV). Desmoglein 1 … Ship refrigerated or frozen. Do not use heat-inactivated serum as this affects test results. Currently, four desmoglein subfamily members have been identified and all are members of the cadherin cell adhesion molecule superfamily.  T The immunoreactivity against keratinocyte cell surfaces at 1:40 dilution of serum samples was judged for immunoadsorption assay. Terms of Use| "Desmoglein 1" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables … The purpose of this study was to characterize the autoantigen of HP. Serum samples from patients with HP were analyzed by immunoblotting, ELISA with rDsg1 and rDsg3, and immunoadsorption assay.  EJablonska to download free article PDFs, After incubation at 4°C overnight, the diluted serum samples were subjected to indirect immunofluorescence on cryosectioned healthy human skin using 1:100 dilution of fluorescein isothiocyanate–conjugated antihuman IgG antibodies (Dako, Copenhagen, Denmark).  RP  LA Pemphigus herpetiformis is a rare clinical expression of nonendemic pemphigus foliaceus, fogo selvagem, and pemphigus vulgaris. 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). Avoid using sera exhibiting a high level of lipemia, hemolysis, icterus or microbial growth. doi:10.1001/archderm.135.8.943.  TOgawa Several sporadic studies characterize the target antigens of HP by immunochemical analyses such as immunoblotting or immunoprecipitation. Daneshpazhooh M(1… Herpetiform pemphigus has some clinical and histological features in common with IgA pemphigus. Ishii K, Amagai M, Komai A, et al. Results of enzyme-linked immunosorbent assays with rDsg1 and rDsg3 demonstrated that of 20 HP serum samples, 16 were positive against Dsg1 and 4 were positive against Dsg3. © 2021 American Medical Association. Therefore, the target molecules of HP remain unclear. Clinical pictures of HP consist of erythematous, urticarial plaques with occasional vesicles in herpetiform arrangement. However, a large-scale study has not been done to determine the autoimmune target for HP. 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).  N All serum samples showed positive staining against keratinocyte cell surfaces by indirect immunofluorescence studies with healthy human skin. Conclusions  To detect IgA-class autoantibodies against Dsg1 and Dsg3, we modified the ELISA by using peroxidase-conjugated antihuman IgA antibodies (Medical and Biological Laboratories) as second antibodies.  MMKonohana sign up for alerts, and more, to access your subscriptions, sign up for alerts, and more, to download free article PDFs, sign up for alerts, customize your interests, and more, to make a comment, download free article PDFs, sign up for alerts and more, Archives of Neurology & Psychiatry (1919-1959), Subscribe to the JAMA Dermatology journal, FDA Approval and Regulation of Pharmaceuticals, 1983-2018, Global Burden of Skin Diseases, 1990-2017, Health Care Spending in the US and Other High-Income Countries, Life Expectancy and Mortality Rates in the United States, 1959-2017, Medical Marketing in the United States, 1997-2016, Practices to Foster Physician Presence and Connection With Patients in the Clinical Encounter, US Burden of Cardiovascular Disease, 1990-2016, US Burden of Neurological Disease, 1990-2017, Waste in the US Health Care System: Estimated Costs and Potential for Savings, Register for email alerts with links to free full-text articles.  EADiaz Immunoadsorption assays with recombinant desmoglein (rDsg) 1 and rDsg3 baculoproteins. Desmoglein 1 (Desmoglein 1, DSG1) Short Description: Component of intercellular desmosome junctions.  PSLazarus  MNishikawa Background: Desmoglein-3.

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.  TKiyokawa 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.  MHall Characterization of autoantibodies in pemphigus using antigen-specific enzyme-linked immunosorbent assays with baculovirus-expressed recombinant desmogleins. Presented in part at International Investigative Dermatology 1998, Cologne, Germany, May 10, 1998. It is predominantly … Koch et al.

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.  B Production of epidermal acantholysis in normal human skin in vitro by the IgG fraction from pemphigus serum. Ishii Results of this study demonstrate that Dsg1 and Dsg3 are the target cell surface antigens of HP. They are characterized by formation of autoantibodies against structural …  KHashimoto They are characterized by formation of autoantibodies against structural proteins of the skin. 1999;135(8):943–947. When the immunoreactivity was not removed even after preincubation with rDsg1 and rDsg3, it indicates that they contain antibodies against the cytoplasmic domain of Dsg1 or Dsg3 or other components of keratinocyte cell surfaces.
