Research Abstract

Monoclonal antibody against glycoprotein H(gH) encoded by varicella-zoster virus(VZV) terminates lytic replication of VZV and induces the quiescently infected cells with dormant but recoverable VZV infectivity. It was demonstrated that autophagic clearance of intracellular gH and shedding microvesicle-mediated VZV virion outside the infected cells.
