Herpes simplex virus type 1 (HSV-1) is a common human pathogen of skin and mucous membranes and is potentially dangerous when the infection is disseminated. Viral morphogenesis, especially the mechanism of viral envelopment and the exact pathway for processing and transport of HSV-1 glycoproteins, is still unclear. We report the results of optimized immunogold-labeled cryosection electron microscopy of HSV-1-infected cultured human fibroblasts (MRC-5). The simplified method presented has proved necessary to obtain reproducible results on cellular distribution of viral glycoproteins. It is now possible to demonstrate the viral glycoprotein gD-1, but not gC-1, in the nuclear membranes and to demonstrate gD-1- and gC-1-labeled viral particles in the perinuclear space, and to show the fate of the viral particles in the endoplasmic reticulum and Golgi area in infected cells.
