The present invention relates to T cell receptors (TCRs) which bind the HLA-A0201 restricted peptide GVYDGREHTV (SEQ ID NO : 1) derived from the MAGE-A4 protein. The TCRs of the invention demonstrate excellent specificity profiles for this MAGE epitope. Also provided are nucleic acids encoding the TCRs cells engineered to present the TCRs cells harbouring expression vectors encoding the TCRs and pharmaceutical compositions comprising the TCRs nucleic acids or cells of the invention.
