SUICIDE TETRAMERS COMPRISING MHC CLASS I AND USES THEREOF

摘要

The present invention provides a cytotoxic MHC I conjugate comprising a cytotoxic moiety, biotinylated MHC I monomers which each comprise an antigenic peptide and streptavidin, bound to the cytotoxic moiety or to a biotinylated cytotoxic moiety and to the biotinylated MHC I monomers. Alternative constructs comprising a cytotoxic moiety and biotinylated MHC I monomers where each monomer comprises an antibody fragment also are provided. The cytotoxic moiety may comprise an 225Ac radionuclide or other cytotoxin. Further provided are methods of killing CD8<+> T cell clonal populations.
