A peptide vaccine complexed so that the peptide vaccine can be delivered specifically to the surface of specific immune cells and a method for delivering a peptide vaccine specifically to the surface of specific immune cells. The peptide vaccine is combined with an IgG binding peptide capable of binding to an IgG that is an agonist against molecules on the surface of specific immune cells such as dendritic cells.

Provided are a tumor antigen polypeptide having the amino acid sequence as shown in SEQ ID NO: 2 or a variant thereof; a nucleic acid encoding the same; a nucleic acid construct, an expression vector, and a host cell containing the encoding nucleic acid; and an antigen presenting cell presenting the tumor antigen polypeptide on the cell surface and an immune effector cell thereof. Also provided is the use of the polypeptide, nucleic acid, antigen presenting cell or immune effector cell in the diagnosis, prevention and treatment of cancers.

The present invention relates to immunogenic immune complexes, related compositions, and related methods.

The present disclosure provides compositions and methods of use to inhibit the interaction of menin with MLL1, MLL2 and MLL-fusion oncoproteins. The compositions and methods of use are useful for the treatment of leukemia, solid cancers, diabetes and other diseases dependent on activity of MLL1, MLL2, MLL fusion proteins, and/or menin.

Antigenic compositions comprising one or more labyrinthin-derived peptides are described herein. In some embodiment, each peptide of the antigenic composition comprises a T-cell epitope and/or a B-cell epitope. In other aspects, the present disclosure provides, e.g., vaccine compositions comprising tin antigenic composition disclosed herein, including kits, medicines, and compositions (such as pharmaceutical compositions and unit dosages) thereof. Also provided are methods of using the compositions disclosed herein, such as methods of treatment thereof and methods of producing antibodies, and antibody compositions thereof, against the one or more labyrinthin-derived peptides or a portion thereof.

The present disclosure provides binding proteins specific for human Wilms tumor protein 1 (WT-1) epitopes, as well as host cells that express the binding proteins. Also provided are polynucleotides that encode a binding protein and vectors that comprise a polynucleotide. Related methods and uses of the presently disclosed compositions are provided for treating diseases or disorders associated with WT-1 expression, such as various cancers.

Provided are T cell receptors (TCR) and TCR variable regions that can selectively bind a Hormad1 peptide/MHC complex. The TCR may be utilized in various therapies, such as autologous Hormad1-TCR adoptive T cell therapy to treat a cancer, such as a solid tumor expressing Hormad1. Methods for expanding related populations of T cells are provided.

The present disclosure relates to a tumor specific neoantigenic peptide, wherein said peptide (i) is encoded by a part of an (ORF) sequence from an unannotated transcript which transcription is positively regulated by an aberrant fusion protein, and (ii) is expressed at a higher level or frequency in a sample from said tumor compared to normal tissue sample. The present disclosure also relates to vaccine or immunogenic composition, antibodies and immune cells derived thereof and their use in therapy of cancer.

The present disclosure provides T-cell modulatory multimeric polypeptides that comprise an immunomodulatory polypeptide, an 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.

Described are means of generating immunological compositions that are universally applicable for induction of immunity to neoplasia regardless of histological origin of tissue. Certain methods concern fibroblasts that are manipulated or dedifferentiated in a manner to induce expression of tumor associated antigens including cancer testis antigens. These cells are used as a source of antigenic stimuli for creation of a cellular vaccine, and/or an exosome vaccine, and/or a lysate-based vaccine.
