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

However, when conjugated to reduced mannan, a significant further reduction of Th1 responses and moderate Th2 responses were induced.
