Research Abstract

Pemphigus (P) is an autoimmune bullous disease caused by disruption of desmosomes due to autoantibodies against desmosomal adhesion molecules, desmoglein 3 (Dsg3) for P vulgaris (PV) or Dsg1 for P foliaceus (PF). It is yet unknown how blisters are induced after PV-IgG bound to desmogleins. The aim of this study is to elucidate the mechanisms of PV-IgG-induced blistering. We have previously shown that PV-IgG causes phosphorylation of Dsg3 followed by depletion of Dsg3 from desmosomes. However, since PV-IgG contains antibodies against other antigens than Dsg3, it is not yet determined whether Dsg3- depletion activity of PV-IgG is due to only anti-Dsg3 activity. In this study we determined that this is caused by anti-Dsg3 activity by using pathogenic and non-pathogenic monoclonal antibodies against Dsg3 in cultured keratinocytes. We also demonstrated that the depletion activity is proportional to the pathogenicity and exerts a decrease in the cell-cell adhesion strength as examined by pipetting dissociation assay. Besides, Epidemolysis bullosa simplex is caused by mutation of keratin 5 or 14, which are the major keratins in epidermal basal cells. We have found out a new type of EBS, caused by a new mutation (K5 : 1649delG) with a new phonotype showing circulated blistering lesions. We made transgenic mice with this mutation of K5 but resulting in no phenotype.
