title: Immunodominant-peptide recognition: beta testing TCRalphabeta.
abstract: In this issue, Ishizuka et al. (2008) define human T cell-receptor recognition of an immunodominant influenza A matrix peptide bound to human leukocyte antigen HLA-A*0201 in atomic detail, raising provocative questions about beta chain function.
