In patients with MS, T cell responses are primarily associated with recognition of the 81–105 region of MBP (QDENPVVHFFKNIVTPRTPPPSQGK) [16], with the MBP83–99 (ENPVVHFFKNIVTPRTP) peptide epitope displaying the strongest binding to HLA-DR2 [17,18], MBP83–96 being the minimal recognized epitope. Here, MBP is linked to myeloid sarcoma.
