The 1.5 A crystal structure of a highly selected antiviral T cell receptor provides evidence for a structural basis of immunodominance.
L.Kjer-Nielsen, C.S.Clements, A.G.Brooks, A.W.Purcell, J.McCluskey, J.Rossjohn.
Despite a potential repertoire of >10(15) alphabeta T cell receptors (TcR), the HLA B8-restricted cytolytic T cell response to a latent antigen of Epstein-Barr virus (EBV) is strikingly limited in the TcR sequences that are selected. Even in unrelated individuals this response is dominated by a single highly restricted TcR clonotype that selects identical combinations of hypervariable Valpha, Vbeta, D, J, and N region genes. We have determined the 1.5 A crystal structure of this "public" TcR, revealing that five of the six hypervariable loops adopt novel conformations providing a unique combining site that contains a deep pocket predicted to overlay the HLA B8-peptide complex. The findings suggest a structural basis for the immunodominance of this clonotype in the immune response to EBV.

Figure 8. Ball and Stick Stereo View Representation of the Public Sequences Selected in the LC13 TcR b Chain and the Residues with which They InteractThe CDR3b subdivided into three regions according to the origin of the relevant codons: Vb (red), Db and N (light blue), and Jb (green). The interacting residues are color-coded yellow (Vb) and gray (Va). Structural superposition of a region of the identical Jb segment from LC13 (green) and B7 (yellow) that highlights the conformational differences.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
