Interestingly, influenza-specific (M158–66) CD8+ T cells in HLA-A2+ RR-MS patients were significantly increased compared to HLA-allele matched healthy controls, but no significant difference was observed in influenza-specific CD8+ T cells (NP265–273) in HLA-A3+ individuals (Fig. 2 B and C). The gene discussed is CD8A; the disease is myeloid sarcoma.
