The present invention relates to T cell receptors (TCRs) which bind the HLA-A2 restricted CLGGLLTMV peptide (SEQ ID NO: 1) derived from the LMP2A protein from Epstein Barr Virus (EBY). TCRs of the invention comprise a TCR alpha chain variable domain and/or a TCR beta variable domain. Certain preferred TCRs also bind the natural peptide variants SLGGLLTMV (SEQ ID NO: 17) and CLGGLITMV (SEQ ID NO: 18) presented as a peptide-HLA-A2 complex. The TCRs of the invention demonstrate excellent specificity profiles for those LMP2A epitopes and have binding affinities for the complex which result in an enhanced ability to recognize the complex compared to a soluble reference TCR having the extracellular sequence of the native EBY LMP2A TCR alpha chain given in FIG. 3 (SEQ ID No: 4) and the extracellular sequence of the native EBY LMP2A TCR beta chain given in FIG. 4 (SEQ ID No: 5).
