Identification of pemphigus vulgaris antigen extracted from normal human epidermis and comparison with pemphigus foliaceus antigen.
Immunoprecipitations of cultured keratinocyte extracts have shown that pemphigus vulgaris (PV) sera bind a polypeptide of 210,000 mol wt with disulfide-linked chains of 130,000 and 85,000 mol wt. To identify proteins in normal human skin recognized by PV antibodies, we performed immunoprecipitations of normal human epidermal extracts. All 22 PV sera tested immunoprecipitated a complex of polype...
متن کاملPemphigus 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...
متن کاملIsolation and purification of a pemphigus vulgaris antigen from human epidermis.
Pemphigus vulgaris is an autoimmune disease associated with an autoantibody directed against a keratinocyte membrane antigen. The purpose of this study was to purify the human pemphigus vulgaris antigen, to produce an antibody to this antigen, and to use the antibody to induce pemphigus in newborn mice. Various techniques to extract the membrane-rich pellet from human epidermal homogenate were ...
متن کاملThymoma with pemphigus foliaceus.
A 75-year-old Japanese woman was referred to us because of an anterior mediastinal mass. Crusts and shallow erosions developed 10 months earlier on her upper chest, back, and scalp. Pemphigus foliaceus was diagnosed based on histological examination of skin biopsy specimens and positivity for serum anti-desmoglein 1 antibody by enzyme-linked immunosorbent assay. Neurological examination and ele...
متن کاملAbsence of intercellular antigens in the deep layers of the epidermis in pemphigus foliaceus.
12 patients with pemphigus foliaceus, a form of pemphigus with lesions that arise in the intercellular substance in the superficial layers of the epidermis, and 7 patients with pemphigus vulgaris, where lesions are in the deep layers, were studied by immunofluorescence. Circulating antibodies to intercellular antigens (IC antibodies) were found in 11 pemphigus foliaceus and 5 pemphigus vulgaris...
