The present invention provides a medicine comprising a Toll-like receptor agonist, LAG-3 protein, a variant or derivative thereof.

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.

The present invention relates to a novel immunity-inducing agent for treatment and/or prevention of cancer. Specifically, the present invention relates to an immunity-inducing agent comprising, as an active ingredient, at least one polypeptide having immunity-inducing activity and selected from polypeptides derived from MRAP2 and modified forms thereof, or a recombinant vector comprising a polynucleotide encoding the polypeptide and capable of expressing the polypeptide in vivo, and a method for inducing immunity, comprising administering the immunity-inducing agent to a subject.

Several embodiments disclosed herein relate to the treatment of a tumor using immunotherapy. Several embodiments relate to the treatment of a liver tumor, such as hepatocellular carcinoma or a metastasis from another tumor location. Additional embodiments relate to combination therapies that employ Natural Killer (NK) cells engineered to express cytotoxic receptor complexes and additional anti-cancer agents to treat tumors.

An immune enhancer comprising at least an interferon and a granulocyte-macrophage colony-stimulating factor, and an immunotherapeutic phar-maceutical composition comprising at least an antigen and the above-mentioned immune enhancers is disclosed. A preparation method of the immunotherapeutic pharmaceutical composition, the use of the immune enhancer and the immunotherapeutic pharmaceutical composition are also disclosed. The immune enhancer can be applied to disease and tumor treatments caused by viruses, bacteria, and other microorganisms.

Chimeric antigen receptor T cell (CARTs) compositions and methods of their use are provided. One embodiment provides a chimeric antigen receptor T cell composition including 8F8 chimeric antigen receptor T cells. Another embodiment provides a chimeric antigen receptor T cell composition including 6G11 chimeric antigen receptor T cells. Still another embodiment provide a chimeric antigen receptor T cell composition including 12D7 chimeric antigen receptor T cells. The disclosed CARTs can be used to treat cancer, for example hepatocellular carcinoma.

The present invention belongs to the field of biotechnology and pharmaceuticals. The present inventors found a sequence motif for identifying potent RIG-I agonists. Accordingly, the present invention is directed to a method for producing RIG-I agonists, the RIG-I agonists produced by said methods, and uses of said RIG-I agonists, as defined in the claims.

A vector harboring nucleic acids encoding a recombinant T cell receptor having antigenic specificity for a DnaJ heat shock protein family member B1-protein kinase cAMP-activated catalytic subunit alpha (DNAJB1-PRKACA) fusion protein is provided, as are host cells and a method for treating fibrolamellar hepatocellular carcinoma with the vector.

The present invention provides a medicine comprising a Toll-like receptor agonist, LAG-3 protein, a variant or derivative thereof.
