  • Publication number: 20220280599
    Abstract: The present invention relates to HLA-DR/CII peptide complexes comprising a chondroitinbinding peptide at the C-terminal end of the polypeptide comprising the H LA-DR alpha chain and/or the H LA-DR beta chain, wherein the CII peptide is fused to the N-terminus of the H LA-DR alpha chain or the H LA-DR beta chain by a linker peptide, for use in treating chronic inflammatory disease, such as arthritis, in human patients.
