Multiple sclerosis (MS), a neuroinflammatory disease that affects millions worldwide, is widely thought to be autoimmune in etiology. Historically, research into MS pathogenesis has focused on autoreactive CD4 T cells, due to their critical role in the animal model, experimental autoimmune encephalomyelitis (EAE), and the association between MS susceptibility and single nucleotide polymorphisms in the MHC II region. However, recent studies have revealed prominent clonal expansions of CD8 T cells within the central nervous system (CNS) during MS. Here we review the literature on CD8 T cells in MS, with an emphasis on their potential effector and regulatory properties. We discuss the impact of disease modifying therapies, currently prescribed to reduce MS relapse rates, on CD8 T cell frequency and function. A deeper understanding of the role of CD8 T cells in MS may lead to the development of more effective and selective immunomodulatory drugs for particular subsets of patients.
