    ..Functional analyses would discern if these allelic differences in the cytoplasmic domain are of functional significance. ..
  2. Okiyama N, Hasegawa H, Oida T, Hirata S, Yokozeki H, Fujimoto M, et al. Experimental myositis inducible with transfer of dendritic cells presenting a skeletal muscle C protein-derived CD8 epitope peptide. Int Immunol. 2015;27:327-32 pubmed publisher
    ..Because this myositis model is mediated by CD8 T cells independently of CD4 T cells, it should be a useful tool to investigate pathology of polymyositis and develop therapies targeting CD8 T cells. ..

    ..Our findings suggest that IL-23 should mediate positive feedback loop from the muscle damage to the T cell activation and be a promising therapeutic target for autoimmune myositis. ..
