This edited volume provides insights about the molecular virology, pathoenesis of infection and host responses to varicella-zoster virus, which is a medically important human herpesvirus. The chapters not only discuss genetics and molecular evolution of the virus, but also new structure-based knowledge on the functions of viral glycoproteins. Further, the authors illustrate how mechanisms from the virus are used to take over and remodel host cells during pathogeneis. These mechanisms also enable viral modulation of host cells and evasion of the host immune response. Part of these evasion and survival strategies, is the reaction to triggered host cell responses like autophagy, the stress response, modulation of apoptosis and other cell death pathways.
