  • Publication number: 20140328868
    Abstract: A first or second polypeptide for use in a method of treating or preventing a disorder by tolerisation, wherein said method comprises administration of the first and second polypeptide; and wherein both first and second polypeptides: i) are of 7 to 30 amino acids in length; ii) comprise at least one MHC Class II-binding T cell epitope; and iii) are a fragment of a protein allergen or a homologous variant of said fragment; wherein said first polypeptide induces the release of an amount of IL-10 that is greater than the amount of IL-10 released in response to the whole protein allergen from which the first polypeptide derives; wherein said disorder is characterised by an inappropriate immune response to the protein allergen from which the second polypeptide derives.
