血凝素(HA)糖蛋白是流感研究的一个重要焦点,因为它在抗原漂移和转移中的作用,以及它的受体结合和膜融合功能,这是病毒进入所不可或缺的。在过去的四十年中,X射线晶体学极大地促进了我们对HA受体结合、膜融合和抗原性的理解。冷冻电镜的最新进展进一步加深了我们对HA生物学的理解。由于HA流感病毒在自然传播的毒株中不断进化,因此总是有新的问题需要回答。几十年来,HA结构生物学知识的不断积累也促进了新疗法和疫苗的设计和开发。这篇综述描述了HA结构生物学领域的现状,我们是如何到达这里的,以及下一步可能是什么。
Hemagglutinin (HA) glycoprotein is an important focus of influenza research due to its role in antigenic drift and shift, as well as its receptor binding and membrane fusion functions, which are indispensable for viral entry. Over the past four decades, X-ray crystallography has greatly facilitated our understanding of HA receptor binding, membrane fusion, and antigenicity. The recent advances in cryo-EM have further deepened our comprehension of HA biology. Since influenza HA constantly evolves in natural circulating strains, there are always new questions to be answered. The incessant accumulation of knowledge on the structural biology of HA over several decades has also facilitated the design and development of novel therapeutics and vaccines. This review describes the current status of the field of HA structural biology, how we got here, and what the next steps might be.
