The morphogenesis of herpes simplex virus type 1 in infected parental mouse L fibroblasts and mutant gro29 cells
Research output: Contribution to journal › Journal article › Research › peer-review
Mutants of cell lines and viruses are important biological tools. The pathway of herpesvirus particle maturation and egress are contentious issues. The mutant gro29 line of mouse L cells is defective for egress of herpes simplex virus type 1 (HSV-1) virions, and a candidate for studies of virus-cell interactions. The properties of uninfected and HSV-1-infected L fibroblasts and gro29 cells investigated by protein assay, immunoblot, titration assay, immunofluorescence light microscopy and immunogold cryosection electron microscopy are reported. The ultrastructure of both HSV-1-infected L and gro29 cells confirmed primary envelopment of virions at the nuclear membranes followed by maturing multiple de-envelopments and re-envelopments in the endoplasmic reticulum and in the Golgi complex. The gro29 cells presented changed cytoskeleton, abolished egress of virions, and were defective in the trafficking of glycoproteins, giving rise to accumulation of viral particles and glycoproteins in the endoplasmic reticulum and the Golgi complex. The results suggest that gro29 cells harbour a causal underlying defect of the cytoskeleton in addition to the HSV-1-induced cytoskeletal changes.
