Abstract:
A diverse library of nucleoproteins each displaying on its surface a polypeptide comprising a native TCR α variable domain sequence or native TCR ß variable domain sequence, in which library the diversity resides in the variety of native TCR α variable domain or native TCR ß variable domain sequences displayed. Such a library is useful for identifying a ligand or ligands of a target peptide-MHC or CD1-antigen.
Abstract:
A proteinaceous particle, for example a bacteriophage, ribosome or cell, displaying on its surface a T-cell receptor (TCR). The displayed TCR is preferably a heterodimer having a non-native disulfide bond between constant domain residues. Such display particles may be used for the creation of diverse TCR libraries for the identificaton of high affinity TCRs. Several high affinities are disclosed.
Abstract:
The present invention relates to T cell receptors (TCRs) that the property of binding to EVDPIGHLY (SEQ ID No: 1) HLA-A1 complex and comprise a TCR alpha chain variable domain and a TCR beta chain variable domain. The EVDPIGHLY peptide is derived from the MAGE-3 protein which is expressed in many tumour types, including melanomas, and other solid tumours such as Head and Neck Squamous Cell, lung, bladder, gastric, prostate, colorectal and esophageal carcimomas. Also provided are nucleic acids encoding such TCRs, cells presenting such TCRs and pharmaceutical compositions comprising such TCRs.

Abstract:
The present invention provides TCRs having an affinity (K D ) of less than or equal to lµM, and/or an off-rate (k off ) of 1x10 -3 S -1 or slower, for the SLYNTVATL-HLA- A* 0201 complex PROVIDED THAT when the said TCR is presented by cell and comprises SEQ ID NOs: 1 and 2, the cell is not a native T cell. Such TCRs are useful, either alone or associated with a therapeutic agent, for targeting HIV infected cells presenting that complex.
