Abstract

Nipah virus (NiV), a highly pathogenic zoonotic paramyxovirus, poses a significant public health threat due to its high mortality rate and potential for human-to-human transmission. The attachment (G) and fusion (F) glycoproteins play pivotal roles in viral entry and host-cell fusion, making them prime targets for therapeutic and vaccine development. Recent advances in structural biology have provided high-resolution insights into the molecular architecture and functional dynamics of these glycoproteins, revealing key epitopes and domains essential for neutralizing antibody responses. The G glycoprotein's head domain and the prefusion F ectodomain have emerged as focal points for vaccine design, with multivalent display strategies showing promise in enhancing immunogenicity and breadth of protection. Structural studies have also informed the development of monoclonal antibodies like m102.4, offering potential post-exposure therapies. Additionally, insights from cryo-electron microscopy and X-ray crystallography have facilitated the design of structure-based inhibitors and next-generation vaccines, including nanoparticle and multi-epitope formulations. This review highlights recent structural findings on the NiV G and F glycoproteins, their implications for therapeutic strategies, and the challenges in developing effective and targeted interventions. A deeper understanding of these glycoproteins will be crucial for advancing NiV-specific therapeutics and vaccines, ultimately enhancing global preparedness against future outbreaks.

摘要

尼帕病毒(NiV)是一种高致病性人畜共患副粘病毒,因其高死亡率和人际传播潜力而对公共卫生构成重大威胁。附着(G)糖蛋白和融合(F)糖蛋白在病毒进入和宿主细胞融合过程中起关键作用,使其成为治疗和疫苗开发的主要靶点。结构生物学的最新进展为这些糖蛋白的分子结构和功能动力学提供了高分辨率的见解,揭示了中和抗体反应所必需的关键表位和结构域。G糖蛋白的头部结构域和融合前F胞外结构域已成为疫苗设计的重点,多价展示策略在增强免疫原性和保护广度方面显示出前景。结构研究也为单克隆抗体(如m102.4)的开发提供了信息,为暴露后治疗提供了潜在选择。此外,冷冻电子显微镜和X射线晶体学的见解促进了基于结构的抑制剂和下一代疫苗的设计,包括纳米颗粒和多表位制剂。本综述重点介绍了关于NiV G和F糖蛋白的最新结构研究结果、它们对治疗策略的影响以及开发有效和靶向干预措施面临的挑战。对这些糖蛋白的更深入理解对于推进NiV特异性治疗和疫苗至关重要,最终增强全球对未来疫情的防范能力。
