Abstract: A method of detecting and isolating cells that produce a secreted protein of interest (POI), for example, an antibody, comprising: a) providing a eukaryotic cell comprising (i) a nucleic acid encoding the POI, and (ii) a nucleic acid encoding a cell surface capture molecule, which comprises a membrane anchor and is capable of binding the POI; (b) culturing the cell under conditions in which the POI and cell surface capture molecule are expressed, and a POI-cell surface capture molecule complex is formed intracellularly and displayed on the cell surface; c) detecting the surface-displayed POI by contacting the cells with a detection molecule, which binds the POI; and d) isolating cells based on the detection molecule.

Abstract: Methods and compositions are provided for integrating coding sequences for antigen-binding proteins such as broadly neutralizing antibodies into a safe harbor locus such as an albumin locus in an animal in vivo.

Abstract: Genetically modified mice comprising a nucleic acid sequence encoding a human M-CSF protein are provided. Also provided are genetically modified mice comprising a nucleic acid sequence encoding a human M-CSF protein that have been engrafted with human cells such as human hematopoietic cells, and methods for making such engrafted mice. These mice find use in a number of applications, such as in modeling human immune disease and pathogen infection; in in vivo screens for agents that modulate hematopoietic cell development and/or activity, e.g. in a healthy or a diseased state; in in vivo screens for agents that are toxic to hematopoietic cells; in in vivo screens for agents that prevent against, mitigate, or reverse the toxic effects of toxic agents on hematopoietic cells; in in vivo screens of human hematopoietic cells from an individual to predict the responsiveness of an individual to a disease therapy, etc.

Abstract: The present invention provides multispecific antibodies that bind to EGFR and CD28 (EGFRxCD28) as well as anti-EGFR antibodies. Such antibodies may be combined with a further therapeutic agent such as an anti-PD1 antibody. Methods for treating cancers (e.g., EGFR-expressing cancer) by administering the antibodies (e.g., and combinations thereof with anti-PD1) are also provided. The EGFRxCD28 antibodies of the present invention embody a tumor-targeted immunotherapeutic modality combined with PD-1 inhibition. These bispecific antibodies bind a tumor-specific antigen (TSA) (EGFR) with one arm and the co-stimulatory receptor, CD28, on T-cells with the other arm. Combination therapy with PD-1 inhibitors specifically potentiated intra-tumoral T cell activation, promoting an effector memory-like T cell phenotype without systemic cytokine secretion in a variety of syngeneic and human tumor xenograft models.

Compositions and methods for generating a genetically modified non-human animal comprising one or more targeted genetic modifications in their germline are also provided.

Abstract: The present invention provides methods for treating an allergy by administering one or more antibodies that bind specifically to the allergen. In certain embodiments, the antibodies useful for treating an allergen, bind specifically to the cat allergen, Fel d1. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to Fel d1. The antibodies of the invention are useful for binding to the Fel d1 allergen in vivo, thus preventing binding of the Fel d1 allergen to pre-formed IgE on the surface of mast cells or basophils. In doing so, the antibodies act to prevent the release of histamine and other inflammatory mediators from mast cells and/or basophils, thus ameliorating the untoward response to the cat allergen in sensitized individuals.

Abstract: The present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD28, and a second antigen-binding molecule that specifically binds human CD-22. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of tumors expressing CD-22, such as B-cell lymphomas. The antibodies and bispecific antigen-binding molecules of the invention are useful for the treatment of diseases and disorders in which an up-regulated or induced targeted immune response is desired and/or therapeutically beneficial.
