  • Patent number: 7459158
    Abstract: The invention relates to methods and materials involved in the treatment and prevention of various diseases such as infections and IgE-related diseases. Specifically, the invention relates to methods and materials that can be used to vaccinate a mammal against specific self or non-self antigens. For example, the methods and materials described herein can be used to reduce the effects of IgE antibodies within a mammal by reducing the amount of total and receptor bound IgE antibodies in the mammal. In addition, the invention provides vaccine conjugates, immunogenic polypeptides, nucleic acid molecules that encode immunogenic polypeptides, host cells containing the nucleic acid molecules that encode immunogenic polypeptides, and methods for making vaccine conjugates and immunogenic polypeptides as well as nucleic acid molecules that encode immunogenic polypeptides. Further, the invention provides an IgE vaccine that induces an anti-self IgE response in a mammal.

  • Patent number: 5653980
    Abstract: The invention relates to a vaccine, preferably for human use, against IgE-mediated allergic reactions. The vaccine contains a protein having the entire amino acid sequence of the constant CH2-CH3 domains of the epsilon chain of the IgE molecule or a structurally stable unit of said amino acid sequence, the protein optionally being coupled to one or more heterologous carrier proteins, and optionally containing an adjuvant. The vaccine is injected, with or without adjuvant, to raise the concentration of endogenous anti-IgE antibodies in the plasma of allergy subjects. In practice, the vaccine can be used against all types of IgE-mediated allergies since the antibodies are not dependent of the antigen specificity of the IgE molecule but will reduce the total IgE pool of the subject. Therefore, the vaccine is aimed at being used for treatment of subjects having different types of IgE-mediated allergies.
