Despite the high diversity of the TCR repertoire, a high degree of cross-reactivity has been reported that could be explained by the "natural" ability of TCR to interact with MHC molecules (MHC focus model) as well as the interaction of TCR to a limited number of amino acids of the peptide bound to the MHC peptide groove. Cross-reactivity can be defined by the ability of a given TCR to interact with more than one pMHC complex with different presented peptides or MHC molecules. Before presenting the experimental approach aiming to quantify the number of peptides recognized by a single TCR, we would like to present clear evidences of the cross-reactivity involving memory T cells without previous antigen encounter. ./cache/cord-352150-ey9kc7zj.txt ./txt/cord-352150-ey9kc7zj.txt
