Pemphigus vulgaris (PV) is an autoimmune epidermal blistering disease in which autoantibodies (IgG) are directed against the desmosomal cadherin desmoglein 3. To better understand how PV IgG alters desmosome morphology and function in vivo, biopsies from patients with PV were analyzed by structured illumination microscopy, a form of superresolution fluorescence microscopy. In patient tissue, de...

There has been no previous clinical-immunological study of pemphigus in Spain. The aim of this study was to perform a retrospective analysis of pemphigus patients who had been followed for a period of 18 years in our centre. We characterized the autoantibody response, compared diagnostic assays and correlated the immunobiological data with phenotype and prognosis. Clinical, epidemiological and ...

Depletion of Ca(2+) ions from epithelial cell cultures has been shown to result in the rapid destruction of intercellular junctions. To understand the mechanism of this effect we have examined how removal of calcium ions from the culture medium of A-431 epithelial cells affects complexes incorporating the cell-cell adhesive receptors, E-cadherin, desmoglein or desmocollin. Sedimentation and bio...

Non-small cell lung cancer can be classified into several histologic subtypes, most commonly lung adenocarcinoma (LADC) or squamous cell carcinoma (SqCC). With the introduction of targeted therapies that can result in dramatically different outcomes based on subtype, the importance of accurate classification has been amplified. Six antibodies (Napsin A, Desmoglein 3, TTF-1, CK5, p63, and tripar...

Recent studies of human disease and transgenic animal experiments have clearly demonstrated the importance of desmosomes in normal tissue architecture. Furthermore, desmosomal components are down-regulated in certain types of carcinomas, suggesting a possible role for desmosomes in suppression of invasion and metastasis. However, there is no functional evidence to support such a hypothesis. To ...

This data article contains extended, complementary analysis related to the research articles entitled "Desmoglein 3, via an interaction with E-cadherin, is associated with activation of Src" (Tsang et al., 2010) [1] and figures related to the review article entitled "Desmoglein 3: a help or a hindrance in cancer progression?" (Brown et al., 2014) [2]. We show here that both Src and caveolin-1 (...

AIMS Arrhythmogenic right ventricular Dysplasia/cardiomyopathy (ARVD/C) is an autosomal dominant inherited cardiomyopathy associated with ventricular arrhythmia, heart failure and sudden death. Genetic studies have demonstrated the central role of desmosomal proteins in this disease, where 50% of patients harbor a mutation in a desmosmal gene. However, clinical diagnosis of the disease remains ...
