Isolated IMP-3-derived epitope peptides having Th1 cell inducibility are disclosed herein. In preferred embodiments, such a peptide of the present invention can promiscuously bind to MHC class II molecules and induce IMP-3-specific cytotoxic T lymphocytes (CTLs) in addition to Th1 cells. Such peptides are thus suitable for use in enhancing immune response in a subject, and accordingly find use in cancer immunotherapy, in particular, as cancer vaccines. Also disclosed herein are polynucleotides that encode any of the aforementioned peptides, APCs and Th1 cells induced by such peptides and methods of induction associated therewith. Pharmaceutical compositions that comprise any of the aforementioned components as active ingredients find use in the treatment and/or prevention of cancers or tumors.

The present disclosure relates to methods for profiling subject specific and personalized T cell receptor (TCR) repertoires using a single-cell sequencing method. More particularly, disclosed are methods for determining binding of T cell receptors to subject specific neoantigens. In addition, the techniques herein may identify the antigenic targets of T cell receptors in the context of tumor neoantigens. Moreover, the present disclosure enables the discovery of T cell targets in numerous diseases, with implications for understanding the basic mechanisms of the mammalian immune response and for developing antigen-specific diagnostic markers and therapies. Finally, cloned TCRs can be used to formulate personalized immunotherapies for those inflicted with a disease, such as cancer.

The present disclosure provides methods for inducing an immune response to hepatitis C virus (HCV) in an individual. The present disclosure provides methods for treating an HCV infection in an individual.

Autologous anti-cancer vaccines and methods of manufacture and treatment are provided, including expansion of individual patient-derived tumor cells in an immune-compromised animal(s) to attain, quantitatively and qualitatively, sufficient material for efficacious vaccine production and utilization, to elicit an immune response against micrometastases and/or recurrence in the individual patient following tumor excision.

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 provides nucleic acids, vectors, host cells, methods and compositions to confer and/or augment immune responses mediated by cellular immunotherapy, such as by adoptively transferring CD8+ central memory T cells or combinations of central memory T cells with CD4+ T cells that are genetically modified to express a chimeric receptor. In some alternatives the genetically modified host cell comprises a nucleic acid comprising a polynucleotide coding for a ligand binding domain, a poly nucleotide comprising a customized spacer region, a polynucleotide comprising a transmembrane domain, and a polynucleotide comprising an intracellular signaling domain. In some alternatives, the ligand binding domains binds to CD171.

The present specification discloses a pharmaceutical composition comprising an active agent that causes reduction of the level of systemic immunosuppression in an individual for use in treating a disease, disorder, condition or injury of the CNS. The pharmaceutical composition is administered by a dosage regimen comprising at least one course of therapy, each course of therapy comprising in sequence a treatment session followed by an interval session of non-treatment.

Provided are methods and compositions for enhancing treatment of a cancer by administering a therapeutic agent for the treatment of a cancer together with a second agent that elevates the level of protein p53. The second agent generates in the tumor a population of dendritic cells expressing at least one of Batf3, IRF5, CD103, and XCR1. The second therapeutic agent can also suppress an autoimmune response to non-cancerous tissue in the patient if generated by an immunotherapeutic agent. The method can further comprise administering a PTEN phosphatase inhibitor.

The present specification discloses recombinant nucleic acid constructs encoding an immunogenic multiepitope polypeptide comprising two or more polypeptides, recombinant nucleic acid constructs encoding at least two epitopes from two or more internal proteins of influenza virus, compositions comprising such recombinant nucleic acid constructs and methods of eliciting a T cell immune response against an influenza virus in a vertebrate using such recombinant nucleic acid constructs and compositions.

The invention relates to the field of prophylaxis and therapy of cancer. Provided is a Indoleamine 2,3-dioxygenase (IDO) or peptide fragments hereof that are capable of eliciting anti-cancer immune responses. Specifically, the invention relates to the use of IDO or peptides derived herefrom or IDO specific T-cells for treatment of cancer. The invention thus relates to an anti-cancer vaccine which optionally may be used in combination with other immunotherapies and to IDO specific T-cells adoptively transferred or induced in vivo by vaccination as a treatment of cancer. The invention also provides that the medicaments herein provided may be used in combination with cancer chemotherapy treatment. The invention further provides the prophylaxis and therapy of infections by the same means as described above. The use of IDO and immunogenic peptide fragments hereof in cancer and infection treatment, diagnosis and prognosis is also provided.
