To assess for … Journal of the American Academy of Dermatology. These antibodies bind to calcium-dependent adhesion molecules in cell surface desmosomes, notably desmoglein 1 (DSG1) in pemphigus foliaceus and desmoglein 3 (DSG3) and/or DSG1 in pemphigus vulgaris. Avoid using sera exhibiting a high level of lipemia, hemolysis, icterus or microbial growth. Indirect immunofluorescence (IIF) studies reveal that both forms of pemphigus are caused by autoantibodies to cell surface antigens of stratified epithelia or mucous membranes and skin. There are three isotypes of desmoglein: Dsg1, Dsg2 and Dsg3. 1 The autoimmune response in the mucosal type of PV is directed against Dsg3, whereas both Dsg1 and Dsg3 … Patients with severe disease can usually be expected to have high titers of antibodies to DSG. If an interpretive report is provided, the reference value field will state this. Monitoring disease activity in pemphigus with enzyme-linked immunosorbent assay using recombinant desmoglein 1 and 3. A positive result indicates the presence of antibodies to recombinant DSG1 and DSG3 and does not specifically identify a certain type of pemphigus. [23].

The identification of desmogleins 1 and 3, desmosomal adhesion glycoproteins, as targets in pemphigus, a fatal autoimmune blistering disease of the skin and mucous membranes, provided the … For initial diagnosis, the preferred test is Pemphigus Antibody Panel - Epithelial Cell Surface Antibodies and Desmoglein 1 and Desmoglein 3 Antibodies, IgG (0090650) or Immunobullous … Desmoglein 1 is a desmosomal cadherin with a molecular weight of 160kD, whereas desmoglein 3 has a molecular weight of 130kD.
