Effect of multiple injections of antigen on prolonged IgE antibody production in hypersensitive mice.

Multiple injections of ovomucoid were given to mice with ongoing prolonged IgE antibody production to that antigen. Two inbred strains and antigen doses ranging from 0.05 to 5 mug each injection, given intradermally and subcutaneously, were used. Mice treated in this manner showed a marked diminution of the Ig E antibody booster response as compared to controls. This decrease in booster response was antigen-specific. In addition, a protective effect from anaphylaxis was indicated. The mouse model continues to be a valuable tool for studies of certain IgE-mediated diseases.
