Epitopes related to coeliac disease
The invention herein disclosed is related to epitopes useful in methods of diagnosing, treating, and preventing coeliac disease. Therapeutic compositions which comprise at least one epitope are provided.
1. An isolated peptide comprising an amino acid sequence representing a glutamine-deamidated counterpart of SEQ ID NO: 1787, wherein:
the glutamine-deamidated counterpart of SEQ ID NO: 1787 is Glu Gln Pro Ile Pro Glu Gln Pro Gln Pro Tyr (SEQ ID NO: 1941); and
the peptide is 15 amino acid residues in length and further comprises a non-natural amino acid added to the N-terminus and/or C-terminus of the peptide.
2. The isolated peptide of claim 1 , wherein the non-natural amino acid is added to the N-terminus of the peptide.
3. The isolated peptide of claim 1 , wherein the non-natural amino acid is added to the C-terminus of the peptide.
4. The isolated peptide of claim 1 , wherein a non-natural amino acid is added both to the C-terminus and to the N-terminus of the peptide.
