| 摘要 |
The present invention relates to a method for eliciting the production in healthy mammals, including humans, of high titer antibodies specific for sites on the extracellular segment of the anchor domain of the membrane-bound .epsilon. heavy chain of B cell-expressed humain IgE by the use of a composition comprising a synthetic peptide immunogen containing extracellular membrane anchor sites, to reduce IgE-secreting B leukocytes and allergeninduced IgE production. It also relates to the use of optimally designed, carrier protein free, IgE .epsilon.-chain related immunogens as key components in a synthetic vaccine to provide an immunotherapy for the treatment of allergy. The subject peptides contain immune stimulator sequences, including a tandemly linked helper T cell epitope, to aid in stimulating the immune response towards the mIgE membrane anchor domain.
