The aim of this study was to assess the correlation between the levels of anti-desmoglein 1 and 3 … Int J Dermatol 2016;55:e184-190. (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. 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. 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. Amagai M, Komai A, Hashimoto T, et al: Usefulness of enzyme linked immunoabsorbent assay using recombinant desmogleins 1 and 3 for sero-diagnosis of pemphigus. Adequate sensitivities and specificity for disease are documented. From: Current … Pemphigus includes a group of often fatal autoimmune blistering diseases characterized by intraepithelial lesions.

Pemphigus vulgaris (PV) is the most common form of pemphigus. Our experience demonstrates a very good correlation between DSG1 and DSG3 results and the presence of pemphigus. 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. 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). Dsg1 and Dsg3 are usually restricted to the stratified squamous epithelia, where blister formation is located in pemphigus. These conditions may cause aberrant test results.
