![]() | ![]() Title: High-resolution in situ structures of hantavirus glycoprotein tetramers. Abstract: New World hantaviruses cause severe infections in humans, with case fatality rates approaching 40%. Previous structural studies have advanced our understanding of hantavirus glycoprotein architecture ...New World hantaviruses cause severe infections in humans, with case fatality rates approaching 40%. Previous structural studies have advanced our understanding of hantavirus glycoprotein architecture and function, however, the lack of high-resolution in situ structures of the glycoprotein tetramer and its lattice organization has limited mechanistic insights into viral assembly, entry, and antigenicity. Here, we leveraged a virus-like particle (VLP) system to establish a cryo-electron microscopy workflow for lattice-forming viral glycoproteins. This enabled the determination of a 2.35 Å resolution structure of the membrane-embedded Andes virus (ANDV) glycoprotein tetramer, as well as structures of dimers of tetramers and a complex with antibody ADI-65534. These structures reveal previously uncharacterized features of glycoprotein organization, stability, and pH-sensing. Immunization of mice with self-amplifying replicon RNA (repRNA) encoding ANDV-VLPs elicited high levels of glycoprotein-binding antibodies but equivalent titers of neutralizing antibodies compared to repRNA-encoded native ANDV glycoprotein complex. Collectively, these findings advance our understanding of hantavirus glycoprotein assemblies and their function, laying a foundation for structure-based vaccine design efforts. | ||||||
