A method for producing an examination reagent includes adding a helper ligand to a receptor protein which is unfolded in an initial solution so as to provide a pre-solution of the examination reagent with a receptor protein which is folded. The receptor protein which is folded comprises a bonded helper ligand which can be exchanged with an examination peptide.

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.

This disclosure provides methods and compositions for detecting Tph cells and/or reducing the number (or frequency) and/or activity of such cells in order to provide therapeutic benefit to a subject having or at risk of developing an autoantibody-associated condition such as an autoantibody-associated autoimmune disease.

Provided herein, inter alia, are methods and compositions for identifying major histocompatibility class II (MEW II) complex binding peptides.

The present invention relates to CTL peptide epitopes, high-throughput methods for their identification, and their uses. In particular, the present invention relates to peptide epitopes for cancer immunotherapy and Hepatitis C Virus vaccines. The present invention also relates to methods and systems for identifying antigen-specific CTLs.

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 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 invention relates to a method for providing a neopeptide-specific T cell, wherein the neopeptide-specific T cell forms a complex having a half-life (T½) of at least 50 s with a neopeptide-MHC monomer. The present invention further relates to a T cell obtainable by the method as well as a pharmaceutical composition comprising such T cells.

A pharmaceutical product containing β2-microglobulin or a functional variant thereof as an active ingredient in the form of liposomes is provided. The product can increase the concentration of β2-microglobulin in the blood, and can also restore a normal HC/β2-microglobulin molar ratio within membrane MHC-I complexes, or prevent a β2-microglobulin deficit from occurring in the MHC-I complexes, of patients suffering from autoimmune diseases. Methods of treating patients with the pharmaceutical product are also presented.

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.
