    摘要: Disclosed are methods for the genetic construction and expression of antibody-based fusion proteins with enhanced circulating half-lives. The fusion proteins of the present invention lack the ability to bind to immunoglobulin Fc receptors, either as a consequence of the antibody isotype used for fusion protein construction, or through directed mutagenesis of antibody isotypes that normally bind Fc receptors. The fusion proteins of the present invention may also contain a functional domain capable of binding an immunoglobulin protection receptor.

    摘要: Disclosed are methods for producing fusion proteins with the heterodimeric cytokine, interleukin-12. In order to insure that the proper ratio of fused and non-fused subunits are obtained in the fusion protein, a specific stepwise approach to genetic engineering is used. This consists of first expressing the non-fused p40 IL-12 subunit in a production cell line, followed by or simultaneously expressing in the same cell, a second recombinant fusion protein consisting of the fused polypeptide linked by a peptide bond to the p35 subunit of IL-12. Molecules containing the p35 fusion protein cannot be secreted from the transfected mammalian cell without first complexing in a one to one ratio with the p40 subunit, thus ensuring the production of active heterodimeric fusion proteins.

    摘要: Methods directed to enhancing the effectiveness of IL-2 in stimulating the immune system is disclosed. According to one method, an antagonist directed against the CD25 subunit of the high-affinity IL-2 receptor complex is administered in conjunction with IL-2. The CD25 antagonist may be an anti-CD25 antibody. According to another method, an anti-IL-2 antibody is administered in conjunction with IL-2. In another method, a mutant IL-2 with diminished ability to bind the CD25 subunit of the high-affinity IL-2 receptor complex is administered. In another method, an CD4 antagonist is administered in conjunction with IL-2 in order to stimulate the immune system.
