T cells recognizing tetanus toxin peptide 'p2' (sequence 830-844) raised in HLA DR6 individuals preferentially express V beta 2 in the TCR. A p2-specific T cell line (60% V beta 2+) was used to compare peptide and superantigen [toxic shock syndrome toxin-1 (TSST-1)]-induced clonal anergy. Many experiments consistently revealed that the degree of 'tolerance' or 'clonal anergy' induced by peptide was greater than with the superantigen TSST-1. These results are of interest in a number of context...Expand abstract
