This peptide fragment is widely utilized in research focused on understanding the immune response in autoimmune diseases, particularly multiple sclerosis (MS). It serves as a key antigen in experimental models to study the mechanisms of demyelination and the role of T-cell activation in autoimmune reactions. Researchers use it to investigate the pathogenesis of MS and to develop potential therapeutic strategies targeting the immune system. Additionally, it is employed in immunological assays to evaluate the specificity and reactivity of antibodies or T-cells associated with autoimmune disorders. Its application extends to screening and testing novel compounds or biologics aimed at modulating immune responses in autoimmune conditions.
