The present invention relates to allergy vaccines and methods of treating and / or preventing asthma, and allergic conditions. The invention is based on the discovery that inhibiting the ligand / receptor interactions involving, e.g., IgE, IL-3, IL-4, IL-5, IL-6, IL-10, IL-13, interferon-alpha, histamine, leukotriene, and their respective receptors, inhibits production of IgE thereby treating or preventing such diseases or conditions. Competitive inhibition of such receptor / ligand interactions is accomplished by immunizing a human or veterinary patient with the interleukin, interferon-alpha, histamine, leukotriene, their receptors, in any combination. Also, the invention relates to inhibiting receptor / ligand interactions involved in IgE production by competitively inhibiting such interactions by administering antibodies to the ligands, receptors, or both, as well as by administering analogs of the receptors (e.g., soluble receptors not associated with a cell).

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. High affinity binding of B-cell epitopes selected from the random aptameric library with antibodies to native pre-determined B-cell epitope of a native protein can be optimized by molecular evolution with error-prone RT-PCR by ribosome display.
