MHC CLASS I H-2DB COMPLEXED WITH A SENDAI VIRUS NUCLEOPROTEIN PEPTIDE
Contents |
Overview
Two synthetic O-GlcNAc-bearing peptides that elicit H-2Db-restricted, glycopeptide-specific cytotoxic T cells (CTL) have been shown to display, nonreciprocal patterns of cross-reactivity. Here, we present the crystal, structures of the H-2Db glycopeptide complexes to 2.85 A resolution or, better. In both cases, the glycan is solvent exposed and available for, direct recognition by the T cell receptor (TCR). We have modeled the, complex formed between the MHC-glycopeptide complexes and their respective, TCRs, showing that a single saccharide residue can be accommodated in the, standard TCR-MHC geometry. The models also reveal a possible molecular, basis for the observed cross-reactivity patterns of the CTL clones, which, appear to be influenced by the length of the CDR3 loop and the nature of, the immunizing ligand.
