Provided are methods of identifying peptide epitopes of an antigen recognized by the non-classical major histocompatibility complex (MHC) molecule designated MHC-E. In some embodiments, the antigen is a tumor antigen, autoimmune antigen or pathogenic antigen. Also provided are methods of identifying peptide binding molecules that bind to a peptide in the context of an MHC-E molecule. In some embodiments, the peptide binding molecule is a T cell receptor (TCR) or antibody, including antigen-binding fragments thereof and chimeric antigen receptors (CAR) thereof. Also provided are methods of genetically engineering cells containing such MHC-E-restricted peptide binding molecules, and such genetically engineered cells, including compositions thereof and uses in adoptive cell therapy. |
