Two HIV-1 isolates were obtained from a patient receiving long-term treatment with zidovudine (ZDV). The in vitro sensitivity to ZDV triphosphate of the reverse transcriptase (RT) from both isolates appeared to be unchanged compared to that of the LAV-Bru HIV-1 reference strain. When isolates were grown in CEM cells (a T-lymphoblastoid tumor cell line) and their RT activity and core antigen (p24) production were determined, the level of p24 production compared to RT activity was high; in infected CEM cells treated with ZDV, RT activity was at background level while the p24 production was still significant, thus indicating a dissociation of RT activity and core antigen production.
从一名接受齐多夫定(ZDV)长期治疗的患者身上获得了两株HIV-1分离株。与LAV-Bru HIV-1参考菌株相比,这两株分离株的逆转录酶(RT)对三磷酸齐多夫定的体外敏感性似乎没有变化。当分离株在CEM细胞(一种T淋巴细胞样肿瘤细胞系)中生长并测定其RT活性和核心抗原(p24)产量时,与RT活性相比,p24产量水平较高;在用ZDV处理的受感染CEM细胞中,RT活性处于背景水平,而p24产量仍然很高,因此表明RT活性与核心抗原产生解离。
