Altered peptide ligands that alter immune responses are a promising approach to the immunotherapy of multiple sclerosis. Cyclic peptides are of interest because the limited stability of linear peptides restricts their use in vivo. We designed and synthesized a cyclic double mutant peptide from MBP87−99-[cyclo(87−99)[A91,A96]MBP87−99]. Immunization of mice, in CFA reduced Th1 responses. However, when conjugated to reduced mannan, a significant further reduction of Th1 responses and moderate Th2 responses were induced.
