What is Dsg1 and Dsg3?
Abstract. Pemphigus is an autoimmune dermatosis in which mucocutaneous blisters are induced primarily by autoantibodies against Desmoglein (Dsg) 1 and 3. Pemphigus vulgaris (PV) usually is associated with autoantibodies against Dsg3 whereas pemphigus foliaceus (PF) patients present autoantibodies against Dsg1.
Where is desmoglein 3 found?
Pemphigus vulgaris antigen (desmoglein 3) is localized in the lower epidermis, the site of blister formation in patients.
What antibodies are found in epidermis for pemphigus vulgaris?
Pemphigus vulgaris This form is associated with the presence of IgG antibodies against desmoglein 3, with or without antidesmoglein 1 antibodies. Patients with both antibodies tend to have more severe or active disease;11 desmoglein 1 antibodies tend to decrease more rapidly on treatment than desmoglein 3 antibodies.
What is pemphigus antibody?
Description: Several blistering skin diseases are associated with specific autoantibodies. Pemphigus, a rare, but serious autoimmune skin disease is associated with serum antibodies directed against the cell surface of epidermal keratinocytes in 90% of patients.
What is Penthagus?
Pemphigus vulgaris (PV) is a rare and serious (potentially life-threatening) condition that causes painful blisters to develop on the skin and lining of the mouth, nose, throat and genitals.
What do desmogleins do?
Desmoglein (Dsg) is a cadherin-like adhesion molecule that functions to maintain tissue integrity and facilitates cell–cell communication. These proteins are the target antigens in epidermal blistering diseases such as pemphigus, caused by autoantibody-mediated acantholysis (disruption of keratinocyte adhesion).
Where are desmogleins located on the desmosome?
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. Desmogleins are protein substances located in and on the surface of keratinocytes.
What kind of disease is backgroundpemphigus vulgaris ( PV )?
BackgroundPemphigus vulgaris (PV) is an autoimmune-blistering disease of the skin and mucous membranes caused by autoantibodies against desmoglein 3 (Dsg3), an Our website uses cookies to enhance your experience.

Can a pemphigus have antibodies to Dsg1?
Many patients with pemphigus foliaceus, a superficial form of pemphigus have antibodies to DSG1. Patients with pemphigus vulgaris, a deeper form of pemphigus, have antibodies to DSG3 and sometimes DSG1 as well.
When to use desmoglein 1 ( Dsg1 ) and 3?
The desmoglein 1 (DSG1) and desmoglein 3 (DSG3) results serve only as an aid to diagnosis and should not be interpreted as diagnostic by themselves. The results should be interpreted in conjunction with clinical evaluation of the patient along with other diagnostic procedures.
