Provided herein are novels systems and methods for the identification of peptides that bind to MHC-I molecules using peptide receptive MHC-I complexes.

The present disclosure provides a chimeric molecule comprising: a) a T-cell modulatory multimeric polypeptide (TMMP); and b) a nucleic acid component, where the nucleic acid component comprises a nucleic acid comprising a nucleotide sequence encoding a chimeric antigen receptor (CAR) comprising an antibody that binds a cancer-associated antigen. The TMMP binds to and activates a target T cell; the nucleic acid component is taken up by the target T cell such that the target T cell expresses the CAR on its surface. The present disclosure provides methods of making the chimeric molecule. The present disclosure provides treatment methods comprising administering the chimeric molecule.

The present invention relates to peptides, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer.

The present invention relates to 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.

The present invention relates to a method for producing a medicament for the treatment or prevention of a tumor in a subject or a diagnostic agent for the detection of a tumor in a subject comprising (A) determining the expression of at least one nucleic acid molecule and/or at least one protein or peptide in a sample obtained from said subject, wherein the at least one nucleic acid molecule is selected from nucleic acid molecules (a) encoding a polypeptide comprising or consisting of the amino acid sequence of any one of SEQ ID NOs 1 to 5, (b) comprising or consisting of the nucleotide sequence of any one of SEQ ID NOs 6 to 10, (c) encoding a polypeptide which is at least 85% identical, preferably at least 90% identical, and most preferred at least 95% identical to the amino acid sequence of (a), (d) consisting of a nucleotide sequence which is at least 95% identical, preferably at least 96% identical, and most preferred at least 98% identical to the nucleotide sequence of (b), (e) consisting of a nucleotide sequence which is degenerate with respect to the nucleic acid molecule of (d), (f) consisting of a fragment of the nucleic acid molecule of any one of (a) to (e), said fragment comprising at least 150 nucleotides, preferably at least 300 nucleotides, more preferably at least 450 nucleotides, and most preferably at least 600 nucleotides, and (g) corresponding to the nucleic acid molecule of any one of (a) to (f), wherein T is replaced by U, and wherein the at least one protein or peptide is selected from proteins or peptides being encoded by the nucleic acid molecule of any one of (a) to (g); and (B) producing a medicament capable of inhibiting the expression of the at least nucleic acid molecule and/or the at least one protein or peptide in the subject, if the at least one nucleic acid molecule and/or at least one protein or peptide is expressed in (A), and/or (B′) producing a diagnostic agent capable of detecting in vivo the sites of expression of the at least nucleic acid molecule and/or the at least one protein or peptide in the subject, if the at least one nucleic acid molecule and/or at least one protein or peptide is expressed in (A).

The present invention relates to a methods for high throughput screening of epitopes that are involved in T cell activation.

The disclosure provides compositions comprising at least one assembly comprising a peptide and a major histocompatibility complex (MHC), wherein the peptide is an integral component of the MHC, wherein the peptide is attached to a surface at its C-terminus through a linker and wherein the peptide is synthesized on the surface. In certain embodiments, the compositions comprise a plurality of assemblies in a spatially-ordered array. The disclosure provides methods for making and using these compositions.

The present application provides inter alia a fusion protein comprising a polypeptide wherein the polypeptide consists of a fragment of invariant chain which is operably linked to an antigenic sequence and wherein the fragment of invariant chain consists of a portion of residues 17-97 of SEQ ID NO: 1, wherein the portion comprises at least 5 contiguous residues from residues 77-92 of SEQ ID NO: 1.

Methods and systems for the efficient and systematic identification of the repertoire of T-cell epitopes.

The present invention relates, inter alia, to compositions and methods, including chimeric proteins comprising an extracellular domain of a Type I transmembrane protein or a portion of a membrane-anchored extracellular protein and a portion of the extracellular domain of a Type II transmembrane protein, wherein the Type II transmembrane protein is naturally expressed on the surface of a Natural Killer (NK) cell that find use in the treatment of disease, such as cancer and viral infections.

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.
