48 (2): 244–52. These antibodies bind to calcium dependent adhesion molecules in cell surface desmosomes, notably desmoglein 1(DSG-1) in pemphigus foliaceus and desmoglein 3 (DSG-3) in pemphigus vulgaris. The identification of the reactive antigens as DSG1 and DSG3 has made it possible to develop highly specific and sensitive enzyme-linked immunosorbent assay methods. (1991) demonstrated that desmoglein-1 is the antigen target in the autoimmune disease of skin, pemphigus foliaceus; DSG3 is the antigen target in pemphigus vulgaris. These desmoglein proteins thus hold cells together, but when the body starts producing antibodies against desmoglein… All Rights Reserved. Antibodies to desmogleins can result in loss of cell adhesion, the primary cause of blister formation in pemphigus. Do not use heat-inactivated serum as this affects test results.

However, in those patients strongly suspected to have pemphigus either by clinical findings or by routine biopsy, and in whom the DSG assay is negative, the indirect immunofluorescence (CIFS / Cutaneous Immunofluorescence Antibodies [IgG], Serum) is recommended. The diagnosis of pemphigus depends on biopsy and serum studies that characterize lesions and detect the autoantibodies that cause them.

Desmoglein 1 and 3 enzyme-linked immunosorbent assay in Iranian patients with pemphigus vulgaris: correlation with phenotype, severity, and disease activity. The 2 main classic types of pemphigus have been identified as pemphigus vulgaris (PV) and pemphigus foliaceus (PF), in which pathogenic IgG autoantibodies are directed against desmosomal transmembrane glycoproteins: desmoglein (Dsg) 3 and Dsg1, respectively. Harman KE, Gratin MJ, Bhogal SJ, et al: The clinical significance of autoantibodies to desmoglein 1 in 78 cases of pemphigus vulgaris. These antibodies bind to calcium dependent adhesion molecules in cell surface desmosomes, notably desmoglein 1(DSG-1) in pemphigus foliaceus and desmoglein 3 (DSG-3) in pemphigus vulgaris. Desmogleins are protein substances located in and on the surface of keratinocytes. Please refer to the original patient report when … A positive result indicates the presence of antibodies to recombinant DSG1 and DSG3 and does not specifically identify a certain type of pemphigus. Desmoglein 1 is a desmosomal cadherin with a molecular weight of 160kD, whereas desmoglein 3 has a molecular weight of 130kD. Avoid using sera exhibiting a high level of lipemia, hemolysis, icterus or microbial growth. A negative result does not rule out the presence of pemphigus. Desmoglein-3 is a protein that in humans is encoded by the DSG3 gene. Desmoglein-3 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).
