Abstract: A method is disclosed wherein an antigenic B-cell epitope is discovered by in vitro transcription and translation of pre-determined sequence on thermostable protein scaffolds detected by antibodies to a native protein. Immune reactivities of IgE B-cell epitopes from pre-determined IgE sequences from the constant region, engaged in binding to high affinity IgE Fc receptors, placed in a loop of green fluorescent protein (GFP) were shown immuno-reactive with anti-IgE. Moreover, the antigenic B-cell epitope can be further optimized by molecular evolution, selected by conformer antibody and receptor on solid phase via ribosome display. Alternatively, a random aptameric antigenic sequence inserted into a loop of the protein scaffold, mimicking a pre-determined sequence of a native protein, can be selected by solid phase conformer antibody and receptor via ribosome display.

Abstract: The present invention concerns the prophylaxis or therapy of immunoglobulin E-mediated disease conditions. The present invention discloses methods for identifying peptides that induce a cytotoxic T-lymphocyte response against immunoglobulin E. The present invention further discloses compositions that are able to elicit in a mammal a cytotoxic T-lymphocyte response to naturally processed and presented immunoglobulin E peptides, and methods for their use.
