In this study, we have evaluated our recently developed method for antigen-cell coupling using sulfosuccinimidyl-4-[N-maleimidomethyl]cyclohexane-1-carboxylate (sulfo-SMCC) heterobifunctional crosslinker in prevention and reversal of experimental autoimmune encephalomyelitis (EAE). We demonstrate that infusion of MOG35–55-coupled spleen cells (MOG-SP) significantly prevents and reverses EAE. Further studies show that the protected animals exhibit significantly delayed EAE upon EAE reinduction. Moreover, adoptive transfer of CD4+ T cells from the protected mice to naïve syngeneic mice renders the recipient mice resistant to EAE induction. Unexpectedly, CD4+ T cell proliferation is similar upon ex vivo stimulation by MOG35–55 amongst all groups. However, further analysis of those proliferating CD4+ T cells shows remarkable differences in Foxp3+ regulatory T cells (70% in MOG-SP groups versus 10–25% in control groups) and in IL-17+ cells (2-3% in MOG-SP groups versus 6–9% in control groups). In addition, we discover that MOG-SP treatment also significantly attenuates MOG35–55-responding IFN-γ-producing Th1 cells. These findings suggest that MOG-SP treatment induces EAE protective MOG35–55-specific regulatory T cells and suppresses EAE pathogenic Th17 and Th1 cells. Our study provides a novel approach for antigen-based EAE immunotherapy, which can potentially be translated into clinical application for immunotherapy of multiple sclerosis.
