Ex vivo expanded regulatory T cells CD4CD25FoxP3CD127 develop strong immunosuppressive activity in patients with remitting-relapsing multiple sclerosis.

Multiple sclerosis (MS) is an autoimmune disease characterized by defect in regulatory function of CD4CD25 T cells. We demonstrated difference in proportion of regulatory T cells CD4CD25FoxP3CD127 (Tregs) within the same patients' relapse and remission. Proportion of peripheral Tregs (pTregs) dropped almost two times in the relapse compare to remission.
