Molecular heterogeneity of the bullous pemphigoid antigens as detected by immunoblotting.

Journal of Immunology 1986 Februrary 16
Sera from 28 patients with bullous pemphigoid (BP), four patients with cicatricial pemphigoid (CP), and 24 controls (normal volunteers and patients with pemphigus, systemic lupus erythematosus, or other skin diseases) were tested against extracts of human epidermis by immunoblotting techniques. The extraction buffer included 1% SDS, 5% beta-mercaptoethanol, and six protease inhibitors with various specificities. BP sera from individual patients showed different patterns of reactivity with the same epidermal extract, and each pattern consisted of one or more bands. A total of five bands of 240 kD, 200 kD, 180 kD, 97 kD, and 77 kD reacted with BP sera; the 240-kD band reacted with one CP sera, and none of these bands was detected by the control sera. The 240-kD and 180-kD bands reacted very strongly with some sera and were most frequently observed (43% and 29%, respectively). The 200-kD, 97-kD, and 77-kD bands were less frequently observed (25%, 7%, and 7%, respectively), but when present, their reactions were usually strong. Eleven percent of the BP sera did not react with any bands. Contrary to previous reports, this study shows that BP autoantibodies react with several protein bands, as detected by immunoblotting. We have recently shown by immunoelectron microscopy that BP autoantibodies bind to the basal cell hemidesmosomes. It remains to be determined which of these protein bands represent specific hemidesmosomal proteins and which antibody-antigen interactions are relevant to the pathogenesis of this disease.
