Little is known of the changes in human immunodeficiency virus type 1 (HIV-1)-specific effector cytotoxic T lymphocytes (CTL) after potent antiretroviral therapy. Using HLA/peptide tetrameric complexes, we show that after starting treatment, there are early rapid fluctuations in the HIV-1-specific CTL response which last 1 to 2 weeks. These fluctuations are followed by an exponential decay (median half-life, 45 days) of HIV-1-specific CTL which continues while viremia remains undetectable. These data have implications for the immunological control of drug-resistant virus.
对于高效抗逆转录病毒治疗后1型人类免疫缺陷病毒(HIV-1)特异性效应细胞毒性T淋巴细胞(CTL)的变化,人们了解甚少。利用HLA/肽四聚体复合物,我们发现开始治疗后,HIV-1特异性CTL反应会出现持续1至2周的早期快速波动。这些波动之后是HIV-1特异性CTL的指数衰减(中位半衰期为45天),在病毒血症仍检测不到时这种衰减仍在继续。这些数据对耐药病毒的免疫控制具有重要意义。
