1.MECHANISM OF ACTION
[Arg91, Ala96] - MBP (87-99) functions as a modified autoantigen that interacts with MHC class II molecules on antigen-presenting cells, forming peptide-MHC complexes recognized by CD4⁺ T cell receptors. The Arg91 and Ala96 substitutions alter the peptide's binding affinity for MHC molecules and its interaction with T cell receptors, potentially modulating the activation threshold of autoreactive T cells. This modified epitope can induce differential T cell responses compared to the wild-type sequence, leading to altered cytokine profiles (Th1/Th2/Th17 polarization) and modified encephalitogenic potential. The peptide serves as a valuable tool for studying how specific amino acid changes in autoantigens influence immune recognition, T cell activation kinetics, and the development of autoimmune pathology in neuroinflammatory models.
