Provided herein are agents that inhibit the function (e.g., the ability to repress Tsp-1) of Protease, Serine 2 (PRSS2) by inhibiting the binding of PRSS2 to LRP1. Further provided herein are control agents that bind to binding domain I of LRP1 and mimic the activity of prosaposin in stimulating Tsp-1 Methods of using these agents in treating cancer are also provided.

Agents that specifically bind TIGIT are disclosed. The TIGIT-binding agents may include polypeptides, antibodies, and/or bispecific agents. Also disclosed are methods of using the agents for enhancing the immune response and/or treatment of diseases such as cancer.

The present invention provides a heterodimeric protein comprising polypeptides that bind each other containing two CH3 regions, wherein amino acid mutations are introduced into CH3 region of the first polypeptide and CH3 region of the second polypeptide to form pairs of amino acids with polar interactions on their interaction interface, thereby forming a heterodimeric protein specifically. The heterodimeric protein of the present invention can prevent Fc mismatch, avoid homodimer formation, and has high yield and good stability.

The invention is directed to treatment of cancer, infections and various inflammatory and autoimmune conditions by affecting regulatory T cell stability and function via a Neuropilin-1:Semaphorin axis.

The present invention pertains to antigen recognizing constructs against COL6A3 antigens. The invention in particular provides novel T cell receptor (TCR) based molecules which are selective and specific for the tumor expressed antigen COL6A3. The TCR of the invention, and COL6A3 antigen binding fragments derived therefrom, are of use for the diagnosis, treatment and prevention of COL6A3 expressing cancerous diseases. Further provided are nucleic acids encoding the antigen recognizing constructs of the invention, vectors comprising these nucleic acids, recombinant cells expressing the antigen recognizing constructs and pharmaceutical compositions comprising the compounds of the invention.

The invention features multi-specific protein complexes with one domain comprising IL-15 or a functional variant, a cytokine receptor or cytokine ligand, and a binding domain specific to a disease antigen, immune checkpoint or signaling molecule.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.
