高活性抗逆转录病毒疗法(HAART)是主要的抗HIV-1疗法,因为它延长了生存期,并将HIV-1感染从致命疾病转变为一种慢性但可控的疾病。不幸的是,在接受长期治疗的患者中,药物毒性和耐药突变株的出现意味着仍然需要持续开发针对HIV-1生命周期中替代分子的新药。HIV-1 Gag前体蛋白是一种多结构域多蛋白,被蛋白水解裂解为主要的成熟衣壳蛋白;CA在HIV-1的形态发生过程中具有多方面的作用,因此被认为是未来抗病毒干预的一个有希望的靶点。在这篇综述中,我们描述了我们在理解HIV-1衣壳结构和核心组装过程中涉及的关键相互作用方面取得的进展,并讨论了这一知识和未来的知识将如何为抗病毒设计提供重要的结构见解。
Highly active anti-retroviral therapy (HAART) is the mainstay anti-HIV-1 therapy as it prolongs survival and switches HIV-1 infection from a fatal disease to a chronic yet manageable one. Unfortunately, drug toxicity and the emergence of drug-resistant mutant strains in patients undergoing long-term therapy have meant that there is still a continual need for novel drugs that target alternative molecules in the HIV-1 life cycle. The HIV-1 Gag precursor protein is a multidomain polyprotein that is proteolytically cleaved into the main, mature capsid protein; CA. CA has multifaceted roles during HIV-1 morphogenesis and is thus regarded as a promising target for future antiviral intervention. In this review, we describe the advances made in our understanding of the HIV-1 capsid structure and the key interactions involved during core assembly, and discuss how this and future knowledge will provide important structural insight for antiviral design.
