摘要 |
Two-domain MHC polypeptides are useful for modulating activities of antigen- specific T-cells, including for modulating pathogenic potential and effects of antigen- specific T-cells. Exemplary MHC class II-based recombinant T-cell ligands (RTLs) of the invention include covalently linked ßl and al domains, and MHC class I-based molecules that comprise covalently linked al and a2 domains. These polypeptides may also include covalently linked antigenic determinants, toxic moieties, and/or detectable labels. The disclosed polypeptides can be used to target antigen-specific T-cells, and are useful, among other things, to detect and purify antigen-specific T-cells, to induce or activate T-cells, to modulate T-cell activity, including by regulatory switching of T-cell cytokine and adhesion molecule expression, to treat conditions mediated by antigen- specific T-cells, to treat or prevent autoimmune or neurodegenerative diseases, to protect axons, and to prevent or reverse demyelination. |
