  • Patent number: 11976103
    Abstract: Provided herein are IL-2 muteins, IL-2 mutein Fc-fusion molecules, anti-IL-2 antibodies, and complexes comprising an anti IL-2 antibody bound to an IL-2 cytokine that preferentially expand and activate T regulatory cells and are amenable to large scale production. Also provided herein are variant human IgG1 Fc molecules lacking or with highly reduced effector function and high stability despite lacking glycosylation at N297. Also provided herein are linker peptides that are glycosylated when expressed in mammalian cells. Also provided herein are methods of making and using the compositions of the present invention.

  • Patent number: 11858999
    Abstract: The present invention relates to IL-17 Receptor A (IL-17RA or IL-17R) antigen binding proteins, such as antibodies, polynucleotide sequences encoding said antigen binding proteins, and compositions and methods for diagnosing and treating diseases mediated by IL-17 Receptor A activation by one or more IL-17 ligands. The present invention relates to the identification of neutralizing determinants on IL-17 Receptor A (IL-17RA or IL-17R) and antibodies that bind thereto. Aspects of the invention also include antibodies that compete for binding with the IL-17RA neutralizing antibodies described herein.

  • Publication number: 20220056144
    Abstract: The invention provides anti-oncostatin M receptor-? (OSMR) antigen binding proteins, e.g., antibodies and functional fragments, derivatives, muteins, and variants thereof. OSMR antigen binding proteins interfere with binding of OSM and/or IL-31 to OSMR. In some embodiments, anti-OSMR antigen binding proteins are useful tools in studying diseases and disorders associated with OSMR and are particularly useful in methods of treating diseases and disorders associated with OSMR and binding of OSM and/or IL-31 to OSMR.
