Distinction between epidermal antigens binding pemphigus vulgaris and pemphigus foliaceus autoantibodies.

Distinction between epidermal antigens binding pemphigus vulgaris and pemphigus foliaceus autoantibodies.

Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are autoimmune blistering diseases in which antibodies develop to the cell surface of epidermal cells. In this study we sought to determine the antigenic specificity of antibodies in the sera of patients with PV and PF. Sera from 12 patients with PV were used to immunoprecipitate extracts of cultured human epidermal cells that were radiolabel...

Pemphigus Vulgaris and Pemphigus Foliaceus

The word “pemphigus” is derived from the Greek term "pemphix” meaning bubble or blister. Pemphigus is a group of autoimmune diseases (see Table 4) characterized by intra-epithelial blistering, resulting in superficial vesicles or bullae that easily rupture, resulting in ulceration of mucosal and/or cutaneous sites. Although rare, pemphigus causes significant morbidity and potential mortality fo...

Treatment of pemphigus vulgaris and pemphigus foliaceus with mycophenolate mofetil.

BACKGROUND Mycophenolate mofetil is increasingly being used as a corticosteroid-sparing agent in immunosuppressive regimens. OBJECTIVE To elucidate the effectiveness of mycophenolate as adjuvant therapy in the treatment of both pemphigus vulgaris and pemphigus foliaceus. DESIGN Historical prospective study. SETTING University hospital. PATIENTS The study included 42 consecutive patients...

Pemphigus vulgaris autoantibodies induce apoptosis

Pemphigus vulgaris (PV) is an autoimmune disease characterized by binding of IgG autoantibodies to epidermal keratinocyte desmosomes. IgG autoantibodies obtained from a patient with mucocutaneous PV reacted with plakoglobin (Plkg) in addition to desmoglein-3 (Dsg3) and Dsg1. Immunofluorescence analysis confirmed that IgG autoantibodies, unlike antibodies from a healthy volunteer, caused disrupt...
