  • Publication number: 20240018239
    Abstract: The present disclosure provides binding proteins, such as antibodies and antigen-binding fragments, which specifically bind to human CD200R1 receptor protein (hu-CD200R1) and are capable of decreasing, inhibiting, and/or fully-blocking immune regulatory effects mediated by hu-CD200R1. The present disclosure also provides methods of using the antibodies (and compositions thereof) to treat diseases and conditions responsive to decreasing, inhibiting and/or blocking immune regulatory function or activity mediated by CD200 binding to CD200R1.

  • Publication number: 20220106395
    Abstract: The present invention provides binding proteins, such as antibodies and antigen-binding fragments, which specifically bind to human interleukin-1 receptor accessory protein (hu-IL1RAP) and fully block the IL-1, IL-33, and IL-36 intracellular signaling pathways. Compositions comprising such binding proteins and methods of making and using such binding proteins are also provided.

  • Patent number: 8252727
    Abstract: Methods for improving antibodies by a variety of DNA diversification and selection procedures are provided. Improvements include increases in affinity, alterations in specificity and effector function, as well as reduced antigenicity, e.g. humanization. Libraries of recombinant antibody sequences are provided, as are cells expressing members of such libraries. Novel phage display vectors are provided. Methods for the coevolution of an antibody and its cognate antigen are provided. Coevolution is used to evolve HIV envelope proteins with increased antigenicity and broadly neutralizing antibodies that interact therewith. Methods of improving antibodies for use in the detection of biological warfare agents are provided.
