In the skin epidermis Desmoglein-3 is expressed in the basal lower layers of the epidermis, and dominates in terms of expression on mucosal surfaces compared to Desmoglein-1. In the palate, the staining for Dsg1 was throughout the epithelium, however much more intense in the superficial layers (Fig. Conclusion: The concluded data suggest that antibodies against desmoglein 1 and desmoglein 3 seem to play a key role in the pathogenesis of oral lichen planus. Titers are expected to decrease with clinical improvement. Furthermore, both of the genes were localized on a 320-kb genomic fragment … them. There was a significant decrease in the levels of anti-Dsg1 and anti-Dsg3, during the follow-up period (p < 0.05). The currently known target antigens are desmoglein 1 (Dsg1), desmoglein 3 (Dsg3), and plakin protein, which act as adhesion molecules between keratinocytes in the epidermis. Diseases associated with DSG3 include Pemphigus and Pemphigus Vulgaris, Familial.Among its related pathways are Keratinization and Apoptotic execution phase.Gene Ontology (GO) annotations related to this gene include calcium ion binding.An important paralog of this gene is DSG4. Two cases of erosive oral lichen planus with autoantibodies to desmoglein 3. Both pemphigus vulgaris antigen (PVA; Dsg3) and pemphigus foliaceus antigen (PFA; Dsg1) are members of the desmoglein subfamily of the cadherin supergene family. of stratified epithelia or mucous membranes and skin. clinical findings or by routine biopsy, and in whom the DSG assay Patients with severe disease can Also, there is a significant decrease in the level of anti-Dsgl and anti-Dsg3 autoantibodies with topical tacrolimus 0.1% ointment. Another desmosomal cadherin, desmocollin, is occasionally recognized by certain pemphigus sera. Despite the commercial availability and less cost of enzyme-linked immunosorbent assays (ELISAs) to detect antidesmoglein 1 (Dsg1) and anti-Dsg3, immunofluorescence is still widely used for confirmation of diagnosis. Harman KE, Gratin MJ, Bhogal SJ, et al: The clinical The identification of significance of autoantibodies to desmoglein 1 in 78 cases of diseases characterized by intraepithelial lesions. Epub 2017 Jul 3. phenotype of pemphigus is defined by the anti-desmoglein DSG3/1-CAART is being designed to target DSG3 and/or DSG1 autoantibodies on pathogenic B cells that cause mcPV. Prussmann W, Prussmann J, Koga H, et al: Prevalence of Many patients antibodies to the major pemphigus antigens, desmoglein 1 and 3. 1b). 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. (d) Acantholysis is widespread n the presence of autoantibodies against both Dsg1 and Dsg3. However, some evidence implies that anti-Dsg1 might be even more representative of the clinical course [ 8 , 15 , 19 ].
