This technique involves the use of TolDC from MS patients cultured in the presence of vitamin D3 (VitD3) and pulsed with myelin peptides to induce a stable hyporesponsiveness in myelin-specific autologous T cells. AIM: The purpose of this study was to analyze the in vivo effect of VitD3-TolDC treatment on experimental autoimmune encephalomyelitis, an animal model of MS. METHODS: Bone marrow-derived TolDC cultured in the presence of VitD3 and pulsed with peptide 40-55 of the myelin oligodendrocyte glycoprotein (MOG40-55 ) were administrated preventively, preclinically, and therapeutically to EAE-induced mice. RESULTS: We found that VitD3-TolDC-MOG treatment showed a beneficial effect, not only decreasing the incidence of the disease but also reducing the severity of the clinical signs mediated by induction of regulatory T cells (Treg), as well as IL-10 production and reduction of Ag-specific lymphoproliferati...
