Pathogenic activity of circulating anti-desmoglein-3 autoantibodies isolated from pemphigus vulgaris patients
INTRODUCTION There are scarce data on immunochemical properties of pemphigus antibodies detected in clinical remission in pemphigus vulgaris (PV) patients. The aim of the study was to compare biological activity of anti-Dsg3 autoantibodies purified from the sera of PV patients in active stage and in clinical remission. MATERIAL AND METHODS The effect of purified antibodies on expression of pr...
متن کاملDesmoglein 3-ELISA: a pemphigus vulgaris-specific diagnostic tool.
BACKGROUND Pemphigus vulgaris (PV) is an autoimmune-blistering disease of the skin and mucous membranes caused by autoantibodies against desmoglein 3 (Dsg3), an epidermal desmosomal adhesion protein of the cadherin family. Cloning of the Dsg3 gene and expression of the protein in a native conformation enabled the recent development of a specific and sensitive enzyme-linked immunosorbent assay (...
متن کاملLoss of correlation between intensities of desmoglein 2 and desmoglein 3 expression in basal cell carcinomas.
Desmosomal cadherins in humans involve three isoforms, each in two splicing variants, of desmocollin (DSC1-3) and four isoforms of desmoglein (DSG1-4). DSGs are transmembranous desmosomal adhesive glycoproteins, which are generally expressed in a differentiation-specific manner. The aim of this study was to measure intensities of expression of both DSG2 and DSG3 in basal cell carcinoma (BCC) an...
متن کاملPrognostic significance of desmoglein 2 and desmoglein 3 in esophageal squamous cell carcinoma.
OBJECTIVE Desmogleins (DSGs) are major members among the desmosomal cadherins critically involved in cell-cell adhesion and the maintenance of normal tissue architecture in epithelia. Reports exploring links of DSG family member expression with cancers are few and vary. The aim of this study was to investigate the ratio of DSG2 and DSG3 mRNA expression in esophageal squamous cell carcinoma (ESC...
متن کاملA Case of Exfoliation of Oral Mucosal Epithelium in a Patient with Anti-Desmoglein 1 Antibody-Positive and Anti-Desmoglein 3 Equivocal Antibody
Pemphigus is an autoimmune bullous disease observed with lesions in the skin and mucosa. Pemphigus is classified by antibodies against desmogleins, which is cadherin type intercellular adhesion factors involved in adhesion between epidermal cells. In this case, because erosion of the oral mucosa was the primary symptom, a relationship with membrane-dominant pemphigus vulgaris was strongly suspe...
