    • A T cell receptor (TCR) having the property of binding to the gp100 YLEPGPVTA peptide-HLA-A2 complex and comprising a TCR alpha variable domain and/or a TCR beta variable domain, characterized in that: (i) said TCR is mutated relative to a TCR having the extracellular alpha and beta chain sequences SEQ ID Nos: 2 and 3 in its alpha chain variable domain amino acids 1 to 109 of SEQ ID No: 2 and/or its beta chain variable domain amino acids 1 to 112 of SEQ ID No: 3; and (ii) said alpha variable domain has at least 90% sequence identity to the amino acid sequence 1 to 109 of SEQ ID No: 2, and/or said beta variable domain has at least 90% sequence identity to the amino acid sequence 1 to 1 12 of SEQ ID No: 3; and (iii) said TCR has a binding affinity for, and/or a binding half-life for, the YLEPGPVTA-HLA-A2 complex at least double that of a reference TCR, the said reference TCR having the extracellular alpha chain sequence SEQ ID No: 45 and the extracellular beta chain sequence SEQ ID No: 46. The use of such TCRs in adoptive therapy, and fusions of such TCRs with therapeutic agents are also described.

    • The present invention provides a dimeric TCR (dTCR) or single-chain TCR (scTCR) associated with selected therapeutic agents, wherein said TCR comprises a first segment constituted by an amino acid sequence corresponding to a TCR a chain variable domain sequence fused to the N terminus of an amino acid sequence corresponding to a TCR a chain constant domain extracellular sequence, a second segment constituted by an amino acid sequence corresponding to a TCR ß chain variable domain fused to the N terminus of an amino acid sequence corresponding to TCR ß chain constant domain extracellular sequence, a disulfide bond between the first and second chains, said disulfide bond being one which has no equivalent in native aß T cell receptors, and in the case of said scTCRs further comprising a linker sequence linking the C terminus of the first segment to the N terminus of the second segment, or vice versa, the length of the linker sequence and the position of the disulfide bond being such that the variable domain sequences of the first and second segments are mutually orientated substantially as in native aß T cell receptors.
