  • a KI α/Vβ3 TG B10.BR × CBA/Ca F1 male mouse was mated with B10.BR female mice. Offspring were tested for the expression of KI TCR α-chain and Vβ3 TG and the expression of KI TCR α-chain in CD4 T cell population was monitored at 4 and 8 wk of age. Mice were categorized based on the percentage of KI TCR α-chain-positive CD4 T cells.
