我们用27例患者的血清对两种不同抗原来源的巴西落叶型天疱疮(BPF)抗原进行了免疫印迹研究。12份血清与人表皮分离液中的150 kD蛋白质发生特异性反应,而18份血清在牛鼻口桥粒制备物中产生类似的蛋白条带。两种样品之间染色强度的多样性表明BPF抗原在表位方面的异质性。日本散发性落叶型天疱疮(Pf)血清的结果相似,但日本寻常型天疱疮(Pv)血清识别130 kD或135 kD的不同抗原,表明BPF与日本Pf相似,但在抗原物质上与Pv不同。此外,本研究表明,免疫印迹分析使用不同的抗原来源应是一个有价值的工具,以确定天疱疮的临床类型。
SummaryWe investigated the Brazilian pemphigus foliaceus (BPf) antigen applying the immunoblotting method to two different antigen sources using 27 patients' sera. Twelve BPf sera reacted specifically with a 150 kD protein in extract of dispase separated human epidermis, while 18 sera yielded a similar protein band in bovine muzzle desmosomal preparation. The diversity of staining intensities between the two samples suggested the heterogeneity of BPf antigens in terms of epitopes. Japanese sporadic pemphigus foliaceus (Pf) sera showed similar results but Japanese pemphigus vulgaris (Pv) sera recognized different antigens of 130 kD or 135 kD, suggesting that BPf is similar to Japanese Pf but is distinct from Pv in respect to the antigenic substance. Furthermore, the present study showed that immunoblot analysis using different antigen sources should be a valuable tool to determine clinical types of pemphigus.
