anti-desmoglein 3 and 1 autoantibodies are involved in the pathogenesis of pemphigus diseases. our objective was to assess the value of elisa in the diagnosis of pemphigus and its correlation with the severity of pemphigus vulgaris. based on clinical presentation and histopathologic confirmation for the diagnosis of the pemphigus, 38 patients took part in the study. sera of the patients were te...

AIMS We determined the contribution of the desmosomal cadherin desmoglein-2 to cell-cell cohesion in cardiomyocytes. In the intercalated disc, providing mechanical strength and electrical communication between adjacent cardiomyocytes, desmoglein-2 is closely associated with N-cadherin and gap junctions. METHODS AND RESULTS We studied intercalated discs of HL-1 cardiomyocytes by immunostaining...

The recent availability of cDNA clones for pemphigus antigens has allowed the production of recombinant desmoglein 1 and desmoglein 3 molecules and the development of an ELISA approach in order to determine levels of antibodies to them. The aim of the study was to determine the relationship between autoantibodies levels and the extent of both mucosal and skin lesions in 20 patients with pemphig...

The integrity of cell-cell junctions in epithelial cells depends on functional interactions of both extracellular and intracellular domains of cadherins with other junction proteins. To examine the roles of the different domains of E-cadherin and desmoglein in epithelial junctions, we stably expressed full length desmoglein 1 and chimeras of E-cadherin and desmoglein 1 in A431 epithelial cells....

During development and progression of malignant melanoma, an important role has been attributed to alterations of cell-cell adhesions, in particular, to a "cadherin switch" from E- to N-cadherin. We have previously shown that a subtype of melanoma cells express the desmosomal cadherin desmoglein 2 as non-junction-bound cell surface protein in addition to classical cadherins. To study the role o...

BACKGROUND Pemphigus vulgaris is a chronic inflammatory disease of skin, the etiology of which is not completely known. Despite the latter, anti-desmoglein antibodies play a proven role in the pathogenesis. Recent studies showed an etiologic effect for prolactin in the pemphigus vulgaris. This study aimed to quantify the correlation between serum prolactin levels and anti-desmoglein antibodies ...

Desmosomes are adhesive intercellular junctions that act as cell surface attachment sites for intermediate filaments. The desmosomal glycoproteins, desmogleins and desmocollins, are members of the cadherin family of adhesion molecules. In addition, desmoglein has been shown to coimmunoprecipitate with the junctional protein plakoglobin. To characterize further the interaction between plakoglobi...

Virulent strains of Staphylococcus hyicus can cause exudative epidermitis in pigs. The major symptom of this disease is exfoliation of the skin in the upper stratum spinosum. Exfoliation of the skin is strongly associated with exfoliative toxin including ExhA, ExhB, ExhC, ExhD, SHETA, and SHETB. Recently, genes for ExhA, ExhB, ExhC and ExhD were cloned. Exfoliative toxins produced by S. aureus ...

BACKGROUND Intravenous immunoglobulin rapidly decreases serum levels of intercellular antibodies in patients with pemphigus vulgaris. However, little is known about the effects of this therapy on antibodies directed specifically against desmoglein 1 and desmoglein 3 and on the IgG subclasses of these antibodies. This study was conducted to study the effect of intravenous immunoglobulin therapy ...
