Antigen presentation stimulates naïve T cells to become either cytotoxic CD8⁺ cells or helper CD4⁺ cells. CD4⁺ and CD8⁺ are receptors that assist the binding of T cell receptors with an antigen presenting cell. The inflammatory sequelae associated with MS may be triggered by an antigen with some epitope homology with one or more myelin-associated protein
