Desmogleins are adhesive glycoproteins that form part of the desmosomal cell junctions.
These proteins are responsible for maintaining the structural integrity of tissues by promoting cell-cell adhesion. Desmogleins are primarily found in epithelial tissues, including the skin, where they help form a barrier against environmental insults.
Desmoglein 1 - DSG1 is predominantly expressed in the upper layers of the epidermis, playing a key role in the adhesion of keratinocytes (skin cells). Its proper function is essential for the maintenance of the skin's barrier, preventing water loss and protecting against pathogens.
Desmoglein 3 - DSG3, on the other hand, is mainly found in the lower layers of the epidermis and is critical for the adhesion of basal and suprabasal keratinocytes. It is particularly important in areas where the skin experiences more mechanical stress, such as the oral mucosa and the scalp.
Purpose of Testing - The primary purpose of testing for desmoglein antibodies is to aid in the diagnosis of pemphigus vulgaris and pemphigus foliaceus. The presence of these antibodies in the blood can confirm the autoimmune nature of the disease and help differentiate between different forms of pemphigus.
1] Blood Sample Collection: A healthcare provider draws a blood sample from a vein, usually in the arm.
2] Laboratory Analysis: The blood sample is sent to a laboratory where it is analyzed for the presence of desmoglein 1 and 3 antibodies. Enzyme-linked immunosorbent assay (ELISA) is commonly used for this purpose.
3] Interpreting Results: Results are generally available within a few days. A positive desmoglein 1 and 3 antibodies test indicates the presence of autoantibodies, supporting a diagnosis of pemphigus.
1] Positive Desmoglein 3 Antibodies: Suggests pemphigus vulgaris.
2] Positive Desmoglein 1 Antibodies: Indicates pemphigus foliaceus.
3] Negative Results: Do not completely rule out pemphigus, as some patients may have negative antibody tests.

The test is performed to help diagnose pemphigus disorders. A positive result can indicate an autoimmune response leading to blister formation in the skin and mucous membranes.
The risks are minimal but may include minor discomfort, bruising, or bleeding at the site where the blood was drawn. There is also a slight risk of infection.
Generally, no special preparation is needed for the blood test. However, inform your healthcare provider about any medications or supplements you are currently taking.
Yes, in addition to the desmoglein antibody test, a skin biopsy and direct immunofluorescence testing can be performed to confirm the diagnosis.
