"HIV epitopes may have developed to be poor immunogens. As a counterapproach HIV vaccine strategy, we used epitope enhancement of a conserved HIV reverse transcriptase (RT) epitope for induction of antiviral protection in HLA-A2-transgenic mice mediated by human HLA-A2-restricted CTLs," investigators in the United States and France report.

"We designed two epitope-enhanced peptides based on affinity for HLA-A2, one substituted in anchor residues (RT-2L9V) and the other also with tyrosine at position 1 (RT-1Y2L9V), and examined the...
