Myelin peptides in multiple sclerosis

The development of specific therapies for organ-specific autoimmune diseases requires the identification of relevant immunogenic epitopes, recognized by both pathogenic T cells and autoantibodies. Here, we review the most relevant studies focused in the identification of peptides in multiple sclerosis (MS) and the distinct T cell reactivity induced in patients compared to controls. Only a few studies reported significant differences in terms of T cell reactivity to them. The current knowledge on this issue, and the diagnostic and therapeutic possibilities opened by the identification of pathogenic MS epitopes are discussed in this paper. © 2009 Elsevier B.V.
