  • Publication number: 20240034759
    Abstract: The present invention provides novel peptides and homologues thereof. The peptides of the invention comprise (i) a T-cell epitope of an antigen (self or non-self) with a potential to trigger an immune reaction presented by a class II major histocompatibility complex (MHC) determinant and recognised by CD4+ T cell more specifically of an allergen or auto-antigen, coupled, optionally through the use of a linker to (ii) an amino acid sequence having a reducing activity, such as a thioreductase sequence. The peptides of the invention have been shown to be useful a medicine, more in particular for the prevention or treatment of immune disorders, more specifically of allergic disorders or autoimmune diseases. The present invention thus provides for the use of said peptides for the manufacture of a medicament for the prevention or treatment of an immune disorder and further provides for methods of treatment or preventing immune disorders by using said peptides.

  • Patent number: 11226332
    Abstract: The present invention relates an in vitro method for detecting class II restricted CD4+ T cells in a sample. Herein a sample is contacted with an isolated complex of an MHC class II molecule and a peptide. This peptide comprises an MHC class II restricted T cell epitope of an antigenic protein and immediately adjacent thereof, or separated by a linker of at most 7 amino acids a sequence with a [CST]-xx-C or C-xx-[CST] motif. CD4+ T cells are detected by measuring the binding of the complex with cells in the sample, wherein the binding of the complex to a cell is indicative for the presence of CD4+ T cells in the sample. The present invention further relates to an isolated complex of an MHC Class II molecule and a peptide comprising an MHC class II restricted T cell epitope of an antigenic protein and immediately adjacent thereof, or separated by a linker of at most 7 amino acids a sequence with a [CST]-xx-C or C-xx-[CST] motif.

  • Publication number: 20210188913
    Abstract: The present invention relates to immunogenic peptides comprising a T-cell epitope. Said peptides are modified such that CD4+ T-cell responses are obtainable that arc much stronger than the CD4+ T-cell responses obtained with the same peptides not comprising said modification. In particular, the modification is the addition of a cysteine, insertion of a cysteine or mutation into a cysteine of a residue at a position adjacent to but outside the MIIC-binding site of the peptide. Further disclosed are the use of such modified peptides in treating, suppressing or preventing diseases such as infectious or allergic diseases and autoimmune diseases, in preventing or suppressing graft rejection, or in the eradication of tumor cells.
