Authors: Ilona Rissanen / Robert Stass / Stefanie A Krumm / Jeffrey Seow / Ruben Jg Hulswit / Guido C Paesen / Jussi Hepojoki / Olli Vapalahti / Åke Lundkvist / Olivier Reynard / Viktor Volchkov / ...Authors: Ilona Rissanen / Robert Stass / Stefanie A Krumm / Jeffrey Seow / Ruben Jg Hulswit / Guido C Paesen / Jussi Hepojoki / Olli Vapalahti / Åke Lundkvist / Olivier Reynard / Viktor Volchkov / Katie J Doores / Juha T Huiskonen / Thomas A Bowden / Abstract: The intricate lattice of Gn and Gc glycoprotein spike complexes on the hantavirus envelope facilitates host-cell entry and is the primary target of the neutralizing antibody-mediated immune response. ...The intricate lattice of Gn and Gc glycoprotein spike complexes on the hantavirus envelope facilitates host-cell entry and is the primary target of the neutralizing antibody-mediated immune response. Through study of a neutralizing monoclonal antibody termed mAb P-4G2, which neutralizes the zoonotic pathogen Puumala virus (PUUV), we provide a molecular-level basis for antibody-mediated targeting of the hantaviral glycoprotein lattice. Crystallographic analysis demonstrates that P-4G2 binds to a multi-domain site on PUUV Gc and may preclude fusogenic rearrangements of the glycoprotein that are required for host-cell entry. Furthermore, cryo-electron microscopy of PUUV-like particles in the presence of P-4G2 reveals a lattice-independent configuration of the Gc, demonstrating that P-4G2 perturbs the (Gn-Gc) lattice. This work provides a structure-based blueprint for rationalizing antibody-mediated targeting of hantaviruses. | |||||||||
