Abstract: Described herein are compositions and kits that comprise an engineered TL1A ligand that displays high stability, minimal binding to decoy receptor DcR3 while retaining functional activity via binding to its cell surface receptor, DR3, and the ability to activate T cells in vitro and in vivo. Methods of making an engineered TL1A ligand and methods of treating a disease or disorder in a subject by administering an engineered TL1A ligand are also provided.

Abstract: Antibodies and antigen binding regions that bind delta-like protein 3 (DLL3) are described. Multispecific antigen-binding constructs, such as bispecific antibodies, containing the antigen-binding regions that bind to DLL3 are also described. The application also describes methods of treatment or detection using the anti-DLL3 antibodies, antigen-binding fragments or multispecific antigen-binding constructs thereof, and related molecules, compositions and methods.

Abstract: The invention provides antigen binding domains that bind human leukocyte antigen G (HLA-G) protein comprising the antigen binding domains that bind HLA-G, polynucleotides encoding them, vectors, host cells, methods of making and using them.

Abstract: Provided herein are novel anti-CD28×anti-PSMA antibodies and methods of using such antibodies for the treatment of PSMA-associated cancers. Subject anti-CD28×anti-PSMA antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and PSMA on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful in combination with other anti-cancer therapies (e.g., anti-CD3×anti-PSMA antibodies) for the treatment of prostate cancers.

Abstract: The disclosure provides antigen binding domains that bind cluster of differentiation 3 (CD3) protein, comprising the antigen binding domains that bind CD3?, polynucleotides encoding them, vectors, host cells, methods of making and using them.

Abstract: VHH domains that bind to p1gR are described. The VHH domain may compete with IgA binding to p1gR, or alternatively, the VHH domain may compete with IgA binding to p1gR. The VHH domains may be coupled to therapeutic agents so as to facilitate delivery of the therapeutic agent to the mucosal layer via p1gR-mediated transcytosis. The therapeutic agent can be a small molecule, large molecule, or even an antibody.

Abstract: A population of antibodies, wherein less than 80% of the oligosaccharides covalently attached to the population of the antibodies via N297 residues thereof comprise a core fucose residue; and wherein the population of the antibodies comprises an antibody which Fc region comprises K338A and T437R mutations, or K248E and T437R mutations.

Abstract: A method is described for delivering a single domain antibody or a therapeutic molecule from an apical surface of a polymeric immunoglobulin receptor (pIgR)-expressing cell to a basolateral surface of the pIgR-expressing cell comprising contacting the pIgR-expressing cell with the single domain antibody or the therapeutic molecule, wherein the single domain antibody binds to pIgR, and the therapeutic molecule comprises an agent and the single domain antibody. A method is also described for transporting such a therapeutic molecule to systemic circulation or lamina propria or gastrointestinal tract of a subject comprising administering the therapeutic molecule to the subject via oral delivery, buccal delivery, nasal delivery or inhalation delivery.
