Research Abstract

We identified novel 3 escape mutations from HIV-1-specific CTLs. We analyzed one escape mutation of them, RT 135 mutation, and found that this mutation accumulated in 9 cohorts. In addition, we showed the accumulation of other 13 escape mutations in these cohorts. These findings demonstrated strong evidence of HIV adaptation to HLA at a population level.
