Abstract
Herpesviruses are large and complex viruses, and have a long evolutionary history with their host species. One poorly understood, but important, area in virus-host interaction is the extensive remodelling of intracellular organelles and morphology that occurs during active viral replication. We have constructed a recombinant reporter virus that allowed us to classify four distinct stages in the infection cycle of herpes simplex virus 1. Single-cell analysis of the impact of the viral load on replication dynamics demonstrates the utility of this times-tamping method for tracking the infection cycle. High-resolution microscopy analysis of cellular structures in live and fixed cells in concert with our dual-fluorescent reporter virus have enabled us to generate a detailed overview over the spatial and temporal organisation of the cytoskeleton and organelles during viral replication. This provides the first systems-level analysis of the morphological changes involved in viral replication.
