Adaptive immunity is predicated on the ability of the T cell repertoire to have
pre-existing specificity for the universe of potential pathogens. Recent findings
suggest that T cell receptor (TCR)-self-major histocompatibility protein (pMHC)
interactions limit autoimmune responses while enhancing T cell response to
foreign antigens. We review these findings here, placing them in context of the
current understanding of how TCR-self-pMHC interactions regulate T cell
activation thresholds, and suggest that TCR-self-pMHC interactions increase the
efficiency of the T cell repertoire by giving a competitive advantage to peptide
cross-reactive T cells. We propose that self-reactivity and peptide
cross-reactivity are controlled by particular CDR3 sequence motifs, which would
allow thymic selection to contribute to solving the feat of broad pathogen
specificity by exporting T cells that are pre-screened by positive and negative
selection for the ability to be 'moderately' peptide cross-reactive.
