  • Title: Isolation of herpes simplex virus-1 by intracellular membranes of BHK tk- cells.
    Author: Dimitriadis VK, Nikolaidis K, Sivropoulou A.
    Journal: Microbios; 1992; 72(291):119-27. PubMed ID: 1337570.
    Abstract:
    Baby hamster kidney (BHK tk-) cells infected with herpes simplex virus-1 (HSV-1) showed a large number of virus particles isolated in vesicles characterized by the presence or the absence of ribosomes or inside cisternae of the rough endoplasmic reticulum or the nuclear envelope. The isolation of the virions by intracellular membranes appeared shortly after infection of the cells by HSV-1. These structures persisted for longer periods where no morphological alterations in the infected cells were noted as well as at periods where expression of the late viral genes and the presence of empty capsids or DNA-containing new capsids in the nucleoplasm of BHK tk- cells were detected. The results suggest that the presence of virions in membranic formations of the infected cells may be an indication of permanent isolation and subsequent deactivation of the viruses rather than an intermediate stage during their transport from the plasma membrane to the nucleus. The possible mechanisms by which the virions are isolated by the intracellular membranes of BHK tk- cells are discussed.
