ABSTRACT:
Disclosed is an antiallergic composition comprising, as an active ingredient, a peptide which is capable of binding to human IgE, more specifically the high-affinity immunoglobulin E receptor .alpha.-chain or a soluble fragment, which is capable of binding to human IgE, or the high-affinity immunoglobulin E receptor .alpha.-chain. The composition is clinically useful for blocking allergic responses. An animal model for use in the screening of prophylactic and therapeutic compositions for IgE-related diseases is also disclosed.
