    摘要: Two kinds of antibody antagonists of the binding of human IL-4 to cellular receptors are provided by this invention. Some of the antagonists bind to specific regions of IL-4 which are believed to be involved in interactions between IL-4 and its receptors. Because of this specific binding by the antibodies to the IL-4, the binding of the IL-4 to the receptors is substantially inhibited. The other antibody antagonists of the invention are anti-idiotypic antibodies which, while lacking IL-4 activity, appear to mimic IL-4 and to compete directly with it for binding to the cellular receptors. Polypeptides used to make the antibody antagonists are also provided, together with methods for using the antagonists to inhibit the binding of IL-4 to its cellular receptors.

    摘要: Novel synthetic polypeptides having amino acid sequences corresponding to the sequence of one or more specific regions of human gamma interferon are provided by this invention. These polypeptides specifically inhibit the binding of human gamma interferon to cellular receptors and the biological activity of such interferon. Antibody antagonists of the binding of human gamma interferon to cellular receptors based Upon the use of the polypeptides as antigens are also provided. Some of these antagonists bind to specific regions of gamma interferon which are believed to be involved in interactions between the intefferon and its receptors. Other antibody antagonists are anti-idiotypic antibodies which appear to compete directly with gamma interferon for binding to the cellular receptors. Also provided are methods for the use of the polypeptides and antibodies as inhibitors of the binding of gamma interferon to its cellular receptors.
