Peptide design and Elispot assay

49 patients

218 peptides

140 pairs (WT Vs. DR)

Protease and Reverse Transcriptase

Epitopes overlapping DR mutations sites were selected.

SummaryPeptides including DR mutations could be considered as immunogens in therapeutic CTL vaccines directed towards immunological-pharmacological strategies to control HIV.

Therapeutic CTL vaccines could prevent selection of DR variants in places where continuous medication supply has not been achieved.

Therapeutic CTL vaccines could control viremia in patients with failure to multiple ART schemes.
