Abstract excerpt
To investigate possible mechanisms behind HIV-1 escape from CTL, we performed detailed longitudinal analysis of Gag (SLYNTVATL)- and RT (ILKEPVHGV)-specific CTL responses and plasma epitope sequences in five individuals. Among those with CTL against consensus epitope sequences, epitope mutations developed over several years, invariably followed by decay of the CTL targeting the consensus epitopes. The maturation...
