Neurodegeneration, including loss of neurons and axons, is a feature of progressive forms of multiple sclerosis (MS). The mechanisms underlying neurodegeneration are mostly unknown. Research implicates autoimmunity to nonmyelin self-antigens as important contributors to disease pathogenesis. Data from our lab
