   <mods:abstract>Multiple sclerosis (MS) is a chronic debilitating disease, in which T-cells are&#xd;
considered to play a pivotal role.&#xd;
CD28 is the quintessential costimulatory molecule on T-cells and its expression&#xd;
declines progressively with repeated stimulations, leading to the generation of&#xd;
CD28− T-cells. Our aim was to examine whether CD4+CD28- T cells were&#xd;
enriched in MS patients, and characterize the phenotype of this subset in MS&#xd;
patients and healthy controls (HC).&#xd;
All these changes could provide these CD4+CD28- T cell characteristics that&#xd;
might be involved in the pathogenesis of MS, turning this T-cell subset into a&#xd;
potential target for future therapeutic strategies.</mods:abstract>
