RSPO surrogates of the invention comprise (i) a specific binding domain for Ring Finger Protein 43 (RNF43) or Zinc and Ring Finger Protein 3 (ZNRF3) and (ii) a cell targeting domain More specifically, wherein the specific binding domain for RNF43 or ZNRF3 is an antibody fragment, and wherein the cell targeting domain is a cytokine.

Abstract: Compositions and methods are provided for peptide sequences that are ligands for a T cell receptor (TCR) of interest, in a given MHC context.

Abstract: De novo designed polypeptides that bind to IL-2 receptor ??cheterodimer (IL-2R??c), IL-4 receptor ??cheterodimer (IL-4R??c), or IL-13 receptor ? subunit (IL-13R?) are disclosed, as are methods for using and designing the polypeptides.

Abstract: This disclosure provides compositions and related methods providing targeted cell-specific inhibition of Notch receptor signaling. The disclosure provides a bi-specific molecule with separate domains that target the intended cell-type and the Notch receptor on that cell-type. The disclosure also provides for nucleic acids, vectors, and cells allowing for the expression of the bi-specific fusion molecules. The disclosure also provides related methods of making and using the bi-specific fusion molecule to inhibit Notch signaling in target cells of interest, including for the treatment of diseases characterized by a dysregulation of Notch signaling.

Abstract: Novel human interleukin-2 (IL-2) muteins or variants thereof, and nucleic acid molecules and variants thereof are provided. Methods for producing these muteins as well as methods for stimulating the immune system of an animal are also disclosed. In addition, the invention provides recombinant expression vectors comprising the nucleic acid molecules of this invention and host cells into which expression vectors have been introduced. Pharmaceutical compositions are included comprising a therapeutically effective amount of a human IL-2 mutein of the invention and a pharmaceutically acceptable carrier. The IL-2 muteins can be used in pharmaceutical compositions for use in treatment of cancer and in stimulating the immune response.

Abstract: Compositions and methods are provided relating to Type III interferons.

Abstract: High affinity CD47 reagents are provided, which (i) comprise at least one amino acid change relative to the wild-type protein; and (ii) have an increased affinity for a SIRP? relative to the wild-type protein. Compositions and methods are provided for modulating phagocytosis in a mammal by administering a therapeutic dose of a pharmaceutical composition comprising a high affinity CD47 reagent, which blocks the physiological binding interaction between SIRP? and a ligand, e.g., native CD47.

Abstract: Engineered orthogonal cytokine receptor/ligand pairs, and methods of use thereof, are provided.

Abstract: Variant IL-13 polypeptides are provided, which are engineered to have one or more of the following properties: (a) altered affinity for IL-13R?2, relative to the native human IL-13 protein; (b) altered affinity for IL-13R?1 relative to the native human IL-13 protein; (c) a disruption in the binding site for IL-4R? relative to the native human IL-13 protein.
