Avoid using sera exhibiting a high level of lipemia, hemolysis, icterus or microbial growth. Desmoglein-3 is a protein that in humans is encoded by the DSG3 gene. Aseptically collect 5-8 mL of blood by approved venipuncture procedures. Tunisian endemic pemphigus foliaceus is associated with desmoglein 1 gene polymorphism. 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). These conditions may cause aberrant test results. Epub 2016 Jun 20. Desmogleins are protein substances located in and on the surface of keratinocytes. 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.

Amagai M, Tsunoda K, Zillikens D, et al: The clinical phenotype of pemphigus is defined by the anti-desmoglein autoantibody profile. No anticoagulants, or preservatives should be added. Pemphigus foliaceus is an autoimmune skin disease mediated by autoantibodies against desmoglein-1… Performance of these assays in the pediatric population has not been established. 2. Patients with severe disease can usually be expected to have high titers of antibodies to DSG. 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. Monitoring disease activity in pemphigus with enzyme-linked immunosorbent assay using recombinant desmoglein 1 and 3. Adequate sensitivities and specificity for disease are documented.

These molecules are involved in the normal … These desmoglein proteins thus hold cells together, but when the body starts producing antibodies against desmoglein… 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. Do not use heat-inactivated serum as this affects test results. Desmoglein 1 and 3 enzyme-linked immunosorbent assay in Iranian patients with pemphigus vulgaris: correlation with phenotype, severity, and disease activity. Desmoglein Antibodies (1 and 3) Test Resources. 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 results should be interpreted in conjunction with clinical evaluation of the patient along with other diagnostic procedures. Pemphigus foliaceous and variants present with skin lesions alone. Pemphigus vulgaris and its variants may present with oral or mucosal lesions alone or with mucosal plus skin lesions. The diagnosis of pemphigus depends on biopsy and serum studies that characterize lesions and detect the autoantibodies that cause them. • Amagai M (February 2003). PMID 12582396.
