== Publication Abstract from PubMed ==

A keystone of antiviral immunity is CD8+ T cell recognition of viral peptides bound to MHC-I proteins. The recognition modes of individual T cell receptors (TCRs) have been studied in some detail, but the role of TCR variation in providing a robust response to viral antigens is unclear. The influenza M1 epitope is an immunodominant target of CD8+ T cells that help to control influenza in HLA-A2+ individuals. Here we show that CD8+ T cells use many distinct TCRs to recognize HLA-A2-M1, which enables the use of different structural solutions to the problem of specifically recognizing a relatively featureless peptide antigen. The vast majority of responding TCRs target a small cleft between HLA-A2 and the bound M1 peptide. These broad repertoires lead to plasticity in antigen recognition and protection against T cell clonal loss and viral escape.

Broad TCR repertoire and diverse structural solutions for recognition of an immunodominant CD8+ T cell epitope.,Song I, Gil A, Mishra R, Ghersi D, Selin LK, Stern LJ Nat Struct Mol Biol. 2017 Feb 27. doi: 10.1038/nsmb.3383. PMID:28250417<ref>PMID:28250417</ref>
