The present invention relates to a bispecific antibody construct comprising a first binding domain which binds to human DLL3 on the surface of a target cell and a second binding domain which binds to human CD3 on the surface of a T cell. Moreover, the invention provides a polynucleotide encoding the antibody construct, a vector comprising said polynucleotide and a host cell transformed or transfected with said polynucleotide or vector. Furthermore, the invention provides a process for the production of the antibody construct of the invention, a medical use of said antibody construct and a kit comprising said antibody construct.

The methods and uses described herein relate to the treatment of age-related conditions, e.g. by administering an agent that inhibits the interaction of GDF11 and follistatin. In some embodiments, the agent can bind to an epitope of GDF11 as described herein.

Disclosed herein is a system that engages skin-resident APCs by directly delivering a vaccine composition, and a system that turns skin cells into a vaccine dispatch center to amplify immunity via the production of engineered extracellular vesicles (EVs) functionalized with targeting ligands and loaded with the vaccine composition that can be targeted to extracutaneous APCs. In particular, disclosed herein is a vaccine composition that involves a first polynucleotide encoding or comprising a viral, bacterial, or tumor antigen, and a second polynucleotide encoding a fusion protein comprising an APC-targeting ligand and an exosomal or lysosomal transmembrane protein. Also disclosed is a method of vaccinating a subject that involves transfecting skin cells of the subject with the disclosed vaccine composition. Also disclosed herein is a method of vaccinating a subject that involves administering to the subject the disclosed EV vaccine.

The methods and uses described herein relate to the treatment of age-related conditions, e.g. by administering an agent that inhibits the interaction of GDF11 and follistatin. In some embodiments, the agent can bind to an epitope of GDF11 as described herein.

In some aspects, the invention relates to compositions and methods of generating antigens, wherein the antigen is a biomolecule that is modified by a reactive oxygen species or a reactive nitrogen species. In some aspects, the invention relates to compositions and methods of generating antibodies that bind to biomolecules that have been modified by a reactive oxygen species or a reactive nitrogen species. In some aspects, the invention relates to compositions and methods of generating antibodies that bind to novel epitopes on unmodified biomolecules. In some aspects, the invention relates to the induction of active immunotherapeutic processes (e.g., using preventive or therapeutic vaccines), which may comprise administering neo-antigens generated through methods and compositions described herein.

A fusion polypeptide is disclosed, which includes: (a) a mucosa targeting polypeptide; (b) a translocating peptide for translocation; and (c) a antigenic epitope. In addition, a method for enhancing a stimulation of an immune response using the aforementioned fusion polypeptide is also disclosed.

The present disclosure relates to compositions and methods for treating disease. More particularly, the disclosure relates to synthetic proteins and their use for treating cancer.

Embodiments of the invention are described, including materials and methods for making molecules and materials that have a specific binding domain of a PlGF2. Embodiments include, for instance, medicaments, biomaterials, biomolecules, molecular fusions, and vaccines.

Disclosed herein are methods and compositions dock and lock (DNL) complexes comprising an AD moiety selected from an AKAP protein and a DDD moiety selected from a protein kinase A regulatory subunit. Also disclosed are fusion proteins comprising an AD moiety or DDD moiety attached to an effector moiety. The DDD moieties form dimers that bind to the AD moiety to form the DNL complexes. The effector moieties may be selected from a wide range of known effector moieties that produce one or more physiological effects, including but not limited to cell death. The DNL complexes may further comprise one or more diagnostic and/or therapeutic agents. The DNL complexes are of use for treating and/or diagnosing a variety of diseases or conditions.
