The present disclosure provides variant immunomodulatory polypeptides, and fusion polypeptides comprising the variant immunomodulatory peptides. The present disclosure provides T-cell modulatory multimeric polypeptides, and compositions comprising same, where the T-cell modulatory multimeric polypeptides comprise a variant immunomodulatory polypeptide of the present disclosure. The present disclosure provides nucleic acids comprising nucleotide sequences encoding the T-cell modulatory multimeric polypeptides, and host cells comprising the nucleic acids. The present disclosure provides methods of modulating the activity of a T cell; the methods comprise contacting the T cell with a T-cell modulatory multimeric polypeptide of the present disclosure.

A therapeutic vaccine and a method of cancer treatment by inducing humoral and cellular immune responses against malignant cells is provided. The vaccine comprises a delivery system that incorporates at least one peptide whose sequence encompasses a genetic mutation associated with a malignancy (neoantigen), at least one immunostimulant, and at least one type of lipid molecule.

Disclosed herein are nucleic acid molecules comprising one or more nucleic acid sequences that encode a mutated consensus PRAME antigen. Vectors, compositions, and vaccines comprising one or more nucleic acid sequences that encode a mutated consensus PRAME antigen are disclosed. Methods of treating a subject with a PRAME-expressing tumor and methods of preventing a PRAME-expressing tumor are disclosed. Mutated consensus PRAME antigen is disclosed.

The present invention relates to compositions, methods, and kits for eliciting an immune response to at least one CMV antigen expressed by a cancer cell, in particular for treating and preventing cancer. CMV determination methods, compositions, and kits also are provided.

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.

Methods and compositions using artificial antigen presenting cells in immunotherapy. The artificial antigen presenting cells comprise substrate particles bound to endogenous MHC-peptide complexes obtained from one or more cells. Methods include administering the artificial antigen presenting cells to a patient to activate antigen-specific T cells.

Methods for producing an antibody or an antigen-binding fragment thereof specifically binding to an antigen of interest, methods for inducing proliferation of PBMCs, B cell activation and differentiation, B cell maturation, and/or promoting class switch in an antibody-producing PBMC to produce IgG, compositions for the in vitro immunization and methods for identifying an antibody-enhancing factor for in vitro immunization.

The present invention provides improved and/or shortened methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for expanding TIL populations in a closed system that lead to improved efficacy, improved phenotype, and increased metabolic health of the TILs in a shorter time period, while allowing for reduced microbial contamination as well as decreased costs. Such TILs find use in therapeutic treatment regimens.
