The invention provides a human cytotoxic T lymphocyte (CTL) agonist epitope from the C-terminal subunit of mucin 1 (MUC1-C), which can be used as a peptide, polypeptide (protein), and/or in vaccine or other composition for the prevention or therapy of cancer. The invention further provides a nucleic acid encoding the peptide, protein, or polypeptide, a vector comprising the nucleic acid, a cell comprising the peptide, polypeptide, nucleic acid, or vector, and compositions thereof.

The compositions and methods are described for generating an immune response to a tumor associated antigen such as MUC-1. The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens for generating a protective immune response to MUC-1 in the subject to which the vector is administered and boosting the immune response by administering a MUC-1 peptide. The compositions and methods of the present invention are useful both prophylactically and therapeutically and may be used to prevent and/or treat neoplasms and associated diseases.

Provided herein are chimeric antigen receptors (CARs) for cancer therapy, and more particularly, CARs containing a scFv from an anti-MUC16 monoclonal antibody. Provided are immune effector cells containing such CARs, and methods of treating proliferative disorders.

Provided are compositions and methods related to improved mucins, methods of making the improved mucins, and cells and cell cultures that express glycosylated mucins. The compositions and methods provide improved cell cultures, and improved methods of producing co-expressed proteins that are distinct from the mucins.

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 presently described subject matter relates to cancer vaccines composed of the signal peptide domain of tumor associated antigens or proteins. The described peptide vaccines have multiple MHC class I and class II epitopes which are highly abundant in the population. Therefore, these vaccines induce a strong, comprehensive immune response against the target proteins in the majority of the vaccinated population, and thereby induce an immune reaction against tumors expressing such target proteins. Specifically, the presently described subject matter relates to peptide vaccines composed of the signal peptide domain of Mucin (MUC1), BAGE-1 or ARMET, and their use for the treatment of cancers which express Mucin (MUC1), BAGE-1 or ARMET.

The present disclosure provides T-cell modulatory multimeric polypeptides that comprise an immunomodulatory N polypeptide, a MUC1 epitope-presenting peptide, and class I MHC polypeptides. A T-cell modulatory multimeric polypeptide is useful for modulating the activity of a T cell, and for modulating an immune response in an individual. The present disclosure provides a T-cell modulatory multimeric polypeptide (TMMP) comprising: a) a first polypeptide; and b) a second polypeptide, wherein the TMMP comprises a MUC1 peptide; a first major histocompatibility complex (MHC) polypeptide; a second MHC polypeptide; one or more immunomodulatory polypeptides; and optionally an immunoglobulin (Ig) Fc polypeptide or a non-lg scaffold.

The invention disclosed herein relates to a method of producing metal particles of a preselected form in a biological system such a glycoprotein.

Provided herein are recombinant poxviruses that are stable through successive passaging of the recombinant poxviruses. More particularly, the recombinant poxviruses comprise one or more modified nucleic acids encoding MUC1, CEA, and/or TRICOM antigens, wherein the recombinant poxviruses are stable through successive passaging. Also, provided herein are compositions and method related thereto.
