PG - 229-31 AB - In an attempt to determine the regions responsible for type I immediate hypersensitivity, a total of 42 peptide fragments, which cover the CH3-CH4 domains in human immunoglobulin E (IgE), were chemically synthesized. Several peptide fragments located in the amino acid sequences Ala329-Thr357 and Arg419-Ala463, inhibited passive cutaneous anaphylaxis (PCA) in vivo. In order to pinpoint the sites responsible for the inhibition of the PCA reaction, various fragment peptides in these two regions were synthesized. As a result, residues Pro343-Leu348, Pro426-Thr433, and Ser456-Thr461 were suggested to be involved in type I immediate hypersensitivity.
