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.

Generation and identification of highly effective immune effector cell in terms of target cell-killing activity can be enhanced by optimizing the proximity between a target cell and the immune effector cell. The cancer-killing T cells described herein can provide highly effective therapies for diverse cancer types, e.g., solid cancers, hematological cancers, and metastatic forms thereof. Provided herein are ex-vivo methods of generating cancer-killing T cells, compositions comprising such immune cells; methods of using the cells, methods of selecting optimal agents for enhancing the target cell killing activity, methods of selecting an optimized immune cell and methods of using this approach to evaluate patient responsiveness to other cancer therapies.

The present disclosure provides novel cell compositions engineered to express at least a chimeric antigen receptor and a survival factor. Methods of using such cell compositions are also described.

A set of target peptides are presented by HLA A*0101, A*0201, A*0301, B*4402, B*2705, B*1402, and B*0702 on the surface of disease cells. They are envisioned to among other things (a) stimulate an immune response to the proliferative disease, e.g., cancer, (b) to function as immunotherapeutics in adoptive T cell therapy or as a vaccine, (c) facilitate antibody recognition of tumor boundaries in surgical pathology samples, (d) act as biomarkers for early detection and/or diagnosis of the disease, and (e) act as targets in the generation antibody-like molecules which recognize the target-peptide/MHC complex.

Provided are compositions that include one or more peptides, wherein each peptide is at least 8 amino acids long and has an amino acid sequence as set forth in any of SEQ ID NOs: 1-45. Also provided are in vitro populations of dendritic cells that include the disclosed compositions, in vitro populations of CD8.sup.+ T cells capable of being activated upon being brought into contact with the disclosed populations of dendritic cells, antibodies or antibody-like molecules that specifically bind to complexes of MHC class I molecules and the disclosed peptides, methods for treating and/or preventing cancer such as leukemia using the disclosed compositions and/or populations, methods for making cancer vaccines using the disclosed compositions, methods for screening target peptides for inclusion in an immunotherapy composition, methods for determining a prognosis of a leukemia patient, and kits that include at least one of the disclosed peptides.

Provided herein are nucleic acids, recombinant adeno-associated virus (rAAV) particles, and compositions, as well as methods of use thereof for inducing immune responses, including protective immune responses for preventing or treating cancer. In some aspects, the rAAV particle includes a nucleic acid that expresses a cancer associated antigen. In some aspects, the rAAV particle is a rAAV particle having a mutation in a surface-exposed amino acid, such as tyrosine, threonine, or serine, that enhances transduction of dendritic cells.

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. In particular, the present invention relates to several novel peptide sequences and their variants derived from HLA class I and class II molecules of human tumor cells that can be used in vaccine compositions for eliciting anti-tumor immune responses or as targets for the development of pharmaceutically/immunologically active compounds and cells.

A peptide consists of the amino acid sequence IYVTSIEQI (SEQ ID NO: 214) in the form of a pharmaceutically acceptable salt, in which the peptide has the ability to bind to an MHC class-I molecule and, when bound to MHC, is capable of being recognized by CD8+ T cells. A composition contains a peptide consisting of the amino acid sequence IYVTSIEQI (SEQ ID NO: 214), an adjuvant, and a pharmaceutically acceptable carrier.
