摘要

The conventional approach to cytotoxic T- lymphocyte (CTL) induction uses maximal antigen concen- tration with the intent of eliciting more CTL. However, the efficacy of this approach has not been systematically explored with regard to the quality of the CTLs elicited or their in vivo functionality. Here, we show that a diametrically opposite approach elicits CTLs that are much more effective at clearing virus. CTLs specific for a defined peptide epitope were selec- tively expanded with various concentrations of peptide antigen.
