HIV-1潜伏期被认为是在抗逆转录病毒治疗存在下根除病毒的最后障碍。体内病毒潜伏期的研究由于在HIV-1患者中发现的潜伏感染细胞的低频率而变得复杂。为了能够研究潜伏期和再活化的信号通路和病毒决定因素,我们开发了一种新的方法,该方法产生大量潜伏的HIV-1感染细胞,这些细胞来自人的初级CD 4 + T淋巴细胞。这种方法允许研究HIV-1潜伏期的不同方面,例如病毒再活化所需的转录因子和所涉及的信号通路。在这篇综述中,我们详细描述了一个实验方案的产生HIV-1潜伏期使用人的原代CD 4 + T细胞。我们还介绍了该领域其他潜伏期模型的要点,沿着每个模型的关键发现。
HIV-1 latency is considered the last hurdle toward viral eradication in the presence of antiretroviral therapy. Studies of viral latency in vivo are complicated by the low frequency of latently infected cells found in HIV-1 patients. To be able to study the signaling pathways and viral determinants of latency and reactivation, we have developed a novel method that generates high numbers of latently HIV-1 infected cells, which are derived from human primary CD4+ T lymphocytes. This method allows for the study of different aspects of HIV-1 latency, such as the transcription factors needed for viral reactivation and the signaling pathways involved. In this review, we describe in detail an experimental protocol for the generation of HIV-1 latency using human primary CD4+ T cells. We also present the salient points of other latency models in the field, along with key findings arising from each model.
