摘要: 目的:测定HIV调节蛋白Tat在HIV脑病发生中的作用。 方法:应用逆转录聚合酶链反应(RT-PCR)方法检测9例伴有HIV脑病和7例不伴有HIV脑病的艾滋病患者脑组织中tat、env及vif mRNA含量。结果:尽管标本取自患者死后较长时间尸检,提取的脑组织RNA已有明显降解,但在伴有HIV脑病病例中,tat mRNA和env mRNA检出率分别为4/9和5/9,而在7例非伴有HIV脑病的病例中,二项指标均为零;vif mRNA在两组病例的检出率分别为5/9和2/7。 结论:Tat对HIV脑病的神经病理改变起着重要作用

Abstract: Objective To determine the role of Tat in mediating HIV encephalitis (HIVE). Methods The contents of tat mRNA in tissue extracts of 9 AIDS patients with HIVE and 7 AIDS patients without HIVE were measured with RT-PCR. Results Despite long autopsy times and significant degradation of RNA extracted from brain tissue, tat mRNA was detected in 4/9 patients with HIVE but not in any of the 7 patients without HIVE. Similarly, the env mRNA was also detected in 5/9 patients with HIVE but not in the patients without HIVE. However, vif mRNA was detected in both groups of patients with HIVE (5/9) or without HIVE (2/7). Conclusion This result suggests that Tat likely plays an important role in the neuropathogenesis of HIVE.
