基于腺相关病毒(AAV)的病毒载体是治疗性基因传递的主要候选者。了解AAV载体进入的限速步骤可用于合理的方法,以提高转导的效率和特异性。这篇综述描述了我们目前对AAV进入的理解,这是感染过程中的关键步骤。我们讨论了AAV受体和附着因子的身份和功能,包括最近发现的多血清型受体AAVR。我们进一步概述了在AAV载体转导的运输阶段起作用的其他宿主因子。特别地,我们关注与从内体到反式高尔基网络的逆行运输相关的细胞蛋白复合物。遗传筛选方法的技术进步促进了AAV-宿主相互作用的新见解,使我们更深入地了解AAV载体如何利用宿主因子将其遗传货物运送到细胞核。
Viral vectors based on adeno-associated virus (AAV) are leading candidates for therapeutic gene delivery. Understanding rate-limiting steps in the entry of AAV vectors may be used in a rational approach to improve efficiency and specificity of transduction. This review describes our current understanding of AAV entry, a key step during infection. We discuss the identity and functions of AAV receptors and attachment factors, including the recently discovered multi-serotype receptor AAVR. We further provide an overview of other host factors that act during the trafficking stage of AAV vector transduction. In particular, we focus on cellular protein complexes associated with retrograde transport from endosomes to the trans-Golgi network. The novel insights in AAV-host interactions facilitated by technological advances in genetic screening approaches provide a greater depth in our understanding how AAV vectors exploit host factors to deliver its genetic cargo to the nucleus.
