Title: Assay for the identification of ige antibody suppressors
Inventor: KATZ DAVID H
IPC: A61P37/06
Filed: 2000-02-15
Abstract: The invention provides an IgE and antigen-specific screening assay for use in identifying agents which suppress the IgE mediated immune response to antigen. The assay is performed in vivo in Animals which hyper respond to antigen by producing exaggerated levels of IgE. The animals are sensitized to an antigen during a specific window of sensitivity which closes a day after the animal has been treated to produce the IgE hyper responsive phenotype.  The screening assay is performed in the animals by treating them with a candidate IgE suppressor agent in conjunction with further immunization made after closure of the window of sensitivity defined by the invention. Positive results (indicating that the candidate agent has IgE suppressive activity) are obtained in the assay through measurement of a decline in antigen-specific IgE in the animal following its treatment with the candidate agent. The screening assay may also be utilized to measure other components of the immune response to antigen, including IgG1 and IgG2a antibody production.
