A polypeptide fragment B (MP-B) has an amino acid sequence shown in SEQ ID NO: 1, in which an amino acid Xaa at position 10 is Arg, Phe, Glu, Thr, or absent, an amino acid Xaa at position 16 is Asn, Val, Leu, Gly, or absent, and an amino acid Xaa at position 25 is Ser, Glu, Met, Arg, or absent. The MP-B can significantly improve the colonic pathologic morphology and decrease a colonic histopathologic score and an expression level of colonic interferon-γ (IFN-γ) in an inflammatory bowel disease (IBD) mouse model, and shows the ability to interfere with the occurrence of IBD in mice.

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 topical composition containing a probiotic and hyaluronic acid or a pharmaceutically acceptable salt thereof, for use in the treatment and/or prevention of inflammatory bowel disease.

The invention provides monoclonal antibodies and antigen-binding fragments thereof specific for TNFR2, and methods of using the same to treat cancer or autoimmune disorder, including combination therapy with antagonists of the PD-1/PD-L1 immune checkpoint.
