A cool hybrid approach to the herpesvirus 'life' cycle.
Zeev-Ben-Mordehai T., Hagen C., Grünewald K.
Electron cryo tomography (cryoET) is an ideal technique to study virus-host interactions at molecular resolution. Imaging of biological specimens in a frozen-hydrated state assures a close to native environment. Various virus-host cell interactions have been analysed in this way, with the herpesvirus 'life' cycle being the most comprehensively studied. The data obtained were further integrated with fluorescence and soft X-ray cryo microscopy data applied on experimental systems covering a wide range of biological complexity. This hybrid approach combines dynamic with static imaging and spans a resolution range from micrometres to angstroms. Along selected aspects of the herpesvirus replication cycle, we describe dedicated combinations of approaches and how subsequent data integration enables insights towards a functional understanding of the underlying processes.
