Production of anti-epithelial antibodies and acantholysis by vaccination with an anti-idiotypic antibody, mimicking desmoglein 1.

Theoretically, the immunization of experimental animals with an anti-idiotype antibody may elicit antibodies that recognize epitopes like the original idiotype; this is archived via internal images. Using this strategy, we attempted to produce anti-epithelial antibodies in Balb/c mice immunized with a pemphigus anti-idiotypic determinant. First, when an anti-idiotype antibody was produced in rabbits by immunization with pemphigus immunoglobulin G (IgG), the anti-idiotypic activity was tested successfully.
