Not just another Fab: the crystal structure of a TcR-MHC-peptide complex

Structure. 1997 Feb 15;5(2):159-63. doi: 10.1016/s0969-2126(97)00175-5.


The structure of a ternary complex formed between a T-cell receptor, a major histocompatibility complex (MHC) protein and a viral peptide provides new insights into the cellular immune response. The results provide a molecular basis for understanding the development of T cells and the reactions leading to transplant rejection and autoimmunity.
