Pemphigus vulgaris is a chronic autoimmune blistering disease characterized by antibody production against Desmogleins 3 (Dsg3) and 1 (Dsg1) causing acantholysis. Increased levels of innate cytokines detected in the blister fluid suggest role immune system activity. To elucidate discrepancy between binding pathogenic antibodies lack formation, we focused on cofactors supporting Here, used dispa...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015210433 DESCRIPTION A 54-year-old man with thymoma (figure 1A, arrow) diagnosed 8 months previously was referred to our hospital because of a 5-month history of painful oral ulcer and odynophagia. Physical examination showed erosion of the lips, pharynx, tongue and ...

Mutations in sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2) underlie Darier disease (DD), a dominantly inherited skin disorder characterized by loss of keratinocyte adhesion (acantholysis) and abnormal keratinization (dyskeratosis) resulting in characteristic mucocutaneous abnormalities. However, the molecular pathogenic mechanism by which these changes influence keratinocyte adhe...

BACKGROUND Cantharidin is a topical vesicant that causes intraepidermal acantholysis with clinical application that includes the removal of warts, molluscum contagiosum (MC), calluses, and acquired perforating dermatoses. OBJECTIVE To provide a comprehensive literature review of the efficacy and safety of cantharidin in the management of various cutaneous conditions. METHODS A PubMed search...

Pemphigus consists of a group of chronic blistering skin diseases mediated by autoantibodies (autoAbs). The dogma that pemphigus is caused by keratinocyte dissociation (acantholysis) as a distinctive and direct consequence of the presence of autoAb targeting two main proteins of the desmosome-desmoglein (DSG) 1 and/or DSG3-has been put to the test. Several outside-in signaling events elicited b...

Pemphigus vulgaris (PV) is an autoimmune bullous skin disease characterized by Abs to the desmosomal cadherin desmoglein-3. Although the autoantibodies have been shown to be pathogenic, the role of the cellular immune system in the pathology of pemphigus-induced acantholysis is unclear. To further delineate the potential role of T cell-signaling pathways in the pathogenesis of PV, we performed ...

Alterations of the p53 gene are the most frequently documented genetic abnormalities in human cancer. The aim of the present study was to analyse if this alteration is an early event in oral tumorigenesis and if the suprabasal expression of p53 is a marker of the presence and severity of epithelial dysplasia. Immunohistochemical p53 expression in 78 specimens of oral squamous cell carcinoma and...

A previous paper (Mahler, M. 1978 J. Gen. Physiol. 71:559--580) describes the time-course of the suprabasal rate of oxygen consumption (delta QO2) in the sartorius muscle of R. pipiens after isometric tetani of 0.1--1.0 s at 20 degrees C. To test whether these were the responses to impulse changes in the rate of ATP hydrolysis, we compared the total suprabasal oxygen consumption during recovery...

Aural cholesteatoma is characterized by invading squamous epithelia with altered growth properties. Cytokeratin (CK) expression is affected in epidermal proliferative diseases and represents the alterations of keratinocyte proliferation, differentiation, and migration. In the present study, the intensity of CK immuno-expression was determined, using densitometry at various sites in experimental...

Mouse polyclonal antisera were raised to the Mr 130,000 and Mr 115,000 cell surface glycoproteins, desmocollins, of desmosomes from bovine nasal epithelium. Immunoblotting confirmed that the antisera were specific for the desmocollins. An immunofluorescence study showed that the antisera distinguished between the basal and suprabasal layers of bovine and human epidermis. The antibodies reacted ...
