Our aim was to examine whether CD4+CD28- T cells wereenriched in MS patients, and characterize the phenotype of this subset in MSpatients and healthy controls (HC).All these changes could provide these CD4+CD28- T cell characteristics thatmight be involved in the pathogenesis of MS, turning this T-cell subset into apotential target for future therapeutic strategies.
