Provided herein are cell penetrating conjugates. The conjugates include non-cell penetrating proteins connected through a phosphorothioate nucleic acid, wherein the phosphorothioate nucleic acid enhances intracellular delivery of the non-cell penetrating proteins. Also provided are methods and kits including the conjugates provided herein.

Provided are methods for efficiently and comprehensively screening antibody repertoires from B cells to obtain and produce molecules with binding characteristics and functional activities for use in human therapy.

The present invention relates to bispecific antibodies which bind to CD3 and EGFR simultaneously. This class of antibody has been demonstrated by the inventors to be useful in the treatment of EGFR tumors by redirecting T cells and forming an immune synapse between activated T cells and EGFR expressing tumor cells, leading to increased levels of killing of EGFR expressing tumor cells. In particular the present invention relates to CD3×EGFR bispecific antibodies selected from the group comprising CD3×EGFR_SF1 (SEQ ID NO: 4, 5 and 6), CD3×EGFR_SF3 (SEQ ID NO: 7, 2 and 8), CD3×EGFR_SF4 (SEQ ID NO: 4, 5 and 9), CD3×EGFR_SD1 (SEQ ID 10 NO: 1, 2 and 10) and CD3×EGFR_SD2 (SEQ ID NO: 11, 10 and 2).

An object of the present invention is to provide an antibody composition, which exhibits an effector function more specifically for a target cell coexpressing two types of antigens that are different from each other and damages the target cell, and also can maintain affinity for the individual target antigens sufficiently high. The present invention relates to an antibody composition against a first antigen and a second antigen that are different from each other, including a first IgG half-molecule and a second IgG half-molecule and relates to the first IgG half-molecule and the second IgG half-molecule constituting the antibody composition.

Disclosed herein are bispecific antibodies comprising a first targeting moiety that specifically binds to CD47 and a second targeting moiety that specifically binds to EpCAM or EGFR and, pharmaceutical compositions and methods comprising the bispecific antibodies.

The present invention provides compositions and methods which involve specifically antagonizing GDF8 and Activin A. In certain embodiments, compositions are provided which comprise a GDF8-specific binding protein and an Activin A-specific binding protein. For example, the invention includes compositions comprising an anti-GDF8 antibody and an anti-Activin A antibody. In other embodiments, antigen-binding molecules are provided which comprise a GDF8-specific binding domain and an Activin A-specific binding domain. For example, the invention includes bispecific antibodies that bind GDF8 and Activin A. The compositions of the present invention are useful for the treatment of diseases and conditions characterized by reduced muscle mass or strength, as well as other conditions which are treatable by antagonizing GDF8 and/or Activin A activity.

Proteins that bind IL-1α and IL-1β are described along with their use in compositions and methods for treating, preventing, and diagnosing IL-1-related disorders and for detecting IL-1α and IL-1β in cells, tissues, samples, and compositions.

The present invention relates to polypeptides directed against or specifically binding to C—X—C Motif chemokine receptor 2 (CXCR2) and in particular to polypeptides capable of modulating signal transduction from CXCR2. The invention also relates to nucleic acids, vectors and host cells capable of expressing the polypeptides of the invention, pharmaceutical compositions comprising the polypeptides and uses of said polypeptides and compositions for treatment of diseases involving aberrant functioning of CXCR2.

The present application is directed to heterodimeric antibodies and methods of use.

Provide herein are variant-Fc-region fusion proteins, variant-Fc-region-antibodies and/or heterodimeric-variant-Fc-region-bispecific-antibodies optionally produced by a host cell line, nucleic acids encoding the variant-Fc-region fusion proteins, variant-Fc-region-antibodies and/or heterodimeric-variant-Fc-region-bispecific-antibodies, host cells containing such nucleic acids, and methods of treatment using the variant-Fc-region fusion proteins, variant-Fc-region-antibodies and/or heterodimeric-variant-Fc-region-bispecific-antibodies, or nucleic acids encoding the variant-Fc-region fusion proteins, variant-Fc-region-antibodies and/or heterodimeric-variant-Fc-region-bispecific-antibodies described herein. Also described are methods of producing the variant-Fc-region fusion proteins, variant-Fc-region-antibodies and/or heterodimeric-variant-Fc-region-bispecific-antibodies in host cells.
