This peptide fragment is primarily used in research to study autoimmune diseases, particularly multiple sclerosis (MS). It is employed to induce experimental autoimmune encephalomyelitis (EAE) in rodent models, which mimics the inflammatory and demyelinating aspects of MS. Researchers utilize this model to investigate the mechanisms of neuroinflammation, immune system responses, and potential therapeutic interventions. The peptide helps in understanding the role of myelin-specific T cells in the pathogenesis of demyelinating diseases and in testing the efficacy of new drugs or treatments aimed at modulating the immune response or promoting remyelination.
