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...
Desmogleins are desmosomal cadherins that mediate cell-cell adhesion. In stratified squamous epithelia there are two major isoforms of desmoglein, 1 and 3, with different distributions in epidermis and mucous membrane. Since either desmoglein isoform alone can mediate adhesion, the reason for their differential distribution is not known. To address this issue, we engineered transgenic mice with...
OBJECTIVE Desmosomes are intercellular junctions that confer strong cell-cell adhesion. Two main members of desmosomal cadherins, desmogleins (DSGs) and desmocollins (DSCs), are involved in carcinogenesis. However, their role in human lung cancer remained elusive. The aims of this study were to analyse the expression of DSCs and to evaluate their clinical application in lung cancer. METHODS T...
Pemphigus is a blistering disease characterized by pemphigus autoantibodies (PVIgG) directed mostly against desmogleins (Dsgs), resulting in the loss of keratinocyte adhesion (acantholysis). Yet, the mechanisms underlying blister formation remain to be clarified. We have shown previously that anti-Fas ligand (FasL) antibody (Ab) prevents PVIgG-induced caspase-8 activation and Dsg cleavage in hu...
Pemphigus is an autoimmune disease characterised by anti-desmoglein (Dsg) antibodies in the serum of patients. The disease can be divided into pemphigus foliaceus and pemphigus vulgaris. Anti-Dsg1 antibody is generally related to pemphigus with cutaneous lesion, and the anti-Dsg3 antibody is related to pemphigus with mucosa lesion. Twenty-nine patients with pemphigus vulgaris were selected in t...
Summary Pemphigus vulgaris (PV) is an autoimmune blistering disease produced by IgG autoantibodies against desmoglein (Dsg)3. Lesions on the skin and mucosa can, in rare cases, be induced by radiotherapy. We report a patient with a history of microprolactinoma and PV, who had only oral lesions from the beginning of her illness but 2 months after treatment with radiotherapy for a breast neoplasi...
Desmogleins (Dsgs), cadherin-type cell adhesion molecules, are targeted in skin-blistering diseases such as pemphigus and staphylococcal scalded skin syndrome (SSSS). The role of Dsg4, a new isoform, was investigated in these diseases. Dsg4 was recognized by 30 (77%) of 39 pemphigus sera containing anti-Dsg1 IgG but not by 16 pemphigus sera containing no anti-Dsg1 IgG or by 34 normal control se...
Plakophilin 3 (PKP3) is a recently described armadillo protein of the desmosomal plaque, which is synthesized in simple and stratified epithelia. We investigated the localization pattern of endogenous and exogenous PKP3 and fragments thereof. The desmosomal binding properties of PKP3 were determined using yeast two-hybrid, coimmunoprecipitation and colocalization experiments. To this end, novel...
Pemphigus is a severe autoimmune blistering disorder, in which immunoglobulin G autoantibodies are directed against desmosomal glycoproteins. The antibodies against desmogleine1 are prevalent in normal subjects living in Tunisia, that suggests the role of environment in the pathogenesis of this endemic type of pemphigus and the need for additional factors to switch from a subclinical form to a ...
