Frequencies of unselected productive Vγ4 rearrangement are expected to be lower than 33% due to an in-frame TAA STOP codon that has to be removed during the recombination process, and have been estimated experimentally to be 16%-18%11,13 .
Significantly different from the respective values observed for T cells; P = .0472 for NKT cells and P = .0089 for αβCD8ααIELs.
Significantly different from values for αβCD8αβIELs; P = .0141 for NKT cells and P = .0353 for αβCD8ααIELs.
Values represent the number of in-frame junction sequences containing stop codons and (in brackets) the percentages of these among in-frame junction sequences; significantly different from the values for conventional T cells (P = .0470 for NKT cells and P = .0119 for αβCD8ααIELs).
Values represent the number of nonproductive junction sequences containing no germline-encoded TAA codon and (in brackets) the percentages of these among nonproductive junction sequences; significantly different from the values for conventional T cells (P = .0297 for NKT cells, P = .0003 for αβCD8ααIELs, and P < .0001 for αβCD8αβIELs).
