The invention relates to non-natural stimulatory primary signalling motifs, which contain the consensus amino acid sequence of Y-X2-L/I-X6-8-Y-X2-L/I. These motifs are extremely efficient at mediating immune cell signal transduction, particularly when incorporated in an intracellular signalling domain of a chimeric receptor. Nucleic acids that encode, and polypeptides that contain, such non-natural stimulatory primary signalling motifs are described, which are suitable for use in medicine. |
