Disclosed are methods for treating a cancer and/or modulating immune CD4+ T cell mediated therapies comprising administering to a subject a fucose. In one aspect, disclosed herein are methods of modulating major histocompatibility complex II human lymphocyte antigen (HLA)-DRB 1 expression on the surface of a cell comprising contacting the cell with an agent that modulates the amount of fucosylation on the cell; wherein an increase in fucosylation increases surface expression of HLA-DRB 1; and wherein a decrease in fucosylation decreases the surface expression of HLA-DRB 1.

Disclosed are compositions and methods for targeted treatment of cancer. The present disclosure provides chimeric antigen receptors and cells expressing such chimeric antigen receptors. In certain embodiments, engineered cells expressing the chimeric antigen receptors are specific for a low density cancer antigen or peptide in groove antigen.

A carrier system that includes a nanocarrier and a peptide non-covalently associated with the nanocarrier. The peptide contains an adaptor peptide sequence fused to the N-terminus of a target peptide, the adaptor peptide sequence being designed to facilitate the association to the nanocarrier. Also disclosed is a method for improving the immunogenicity of a peptide antigen by fusing it to an adaptor peptide sequence to form an immunizing peptide and contacting the immunizing peptide with a compatible nanocarrier. Further, a method is provided for treating a condition by immunization with a target peptide that has been fused to an adaptor peptide sequence and thereby associated with a nanocarrier. The method induces an immune response against the target peptide for treating cancer, viral infection, bacterial infection, parasitic infection, autoimmunity, or undesired immune responses to a biologies treatment.

Disclosed herein are methods for selecting cancer patients for autologous cancer vaccine therapy and methods for predicting survival of cancer patients after autologous cancer vaccine therapy comprising, measuring the level of soluble programmed cell death protein-1 (sPD-1) in the blood of the patient.

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 disclosure relates to a new peptide; a new fusion polypeptide, a polynucleotide or vector encoding same; a pharmaceutical composition or immunogenic composition or vaccine comprising said peptide; use of said peptide, vector, pharmaceutical composition, immunogenic composition or vaccine to treat cancer; a method of treating cancer using said peptide, fusion polypeptide, polynucleotide, vector, pharmaceutical composition, immunogenic composition or vaccine; an ex vivo method of stimulating and/or amplifying T-cells; and a combination therapeutic for the treatment of cancer comprising said peptide fusion polypeptide, polynucleotide, vector, pharmaceutical composition, immunogenic composition or vaccine.

The invention relates to a peptide comprising an amino acid sequence selected from the group consisting of (i) SEQ ID NO: 1 to SEQ ID NO: 216, and (ii) a variant sequence thereof which maintains capacity to bind to MHC molecule(s) and/or induce T cells cross-reacting with said variant peptide, or a pharmaceutically acceptable salt thereof.

The present invention relates to compositions and methods for generating a nucleic acid delivery system comprising a nucleic acid sequence encoding a heterologous protein comprising a canine tumor-specific antigen (canine melanoma polyepitope (K9Melapoly)) and an inhibitor of an immuno-inhibitory pathway (HSV-1 gD). Additionally, the current invention includes compositions and methods of treating and/or preventing or immunizing a canine against melanoma, and methods of inducing an effector and memory T cell immune response in a canine administered the nucleic acid delivery system of the invention. Furthermore, the invention encompasses a pharmaceutical composition for vaccinating a canine as well as a protein expression system.

The present invention relates to neoplasia vaccine or immunogenic composition administered in combination with other agents, such as checkpoint blockade inhibitors for the treatment or prevention of neoplasia in a subject
