Stability of neurotropic mouse hepatitis virus (JHM strain) during chronic infection of neuroblastoma cells. 1978

S A Stohlman, and L P Weiner

A line of mouse neuroblastoma cells which was chronically infected with the neurotropic strain (JHM) of MHV, a member of the coronavirus group, was established. These cells, designated NJ, exhibited typical MHV cytopathic effects (CPE) at all passage levels along with the continual production of infectious virus. Most cells were positive for viral antigen by immunoflourescence. Viral particles consistent with the morphology of MHV were found by electron microscopy. The uninfected neuroblastoma cell line did not contain a detectable population of cells resistant to JHM, and persistence did not elicit the production of interferon. No plaque morphology or temperature sensitive mutants were selected for in the NJ culture, and we were unable to detect the presence of either a defective or defective interfering virus population. The addition of low concentration antiviral antibody modulated the infection to a carrier culture with viral antigen in the cytoplasm of the cells, but no infectious virus was produced, and the cells lacked both surface viral antigen and CPE. Possible mechanisms of viral persistence in vitro are discussed.

UI	MeSH Term	Description	Entries
D009447	Neuroblastoma	A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.

D002460	Cell Line	Established cell cultures that have the potential to propagate indefinitely.	Cell Lines,Line, Cell,Lines, Cell
D003588	Cytopathogenic Effect, Viral	Visible morphologic changes in cells infected with viruses. It includes shutdown of cellular RNA and protein synthesis, cell fusion, release of lysosomal enzymes, changes in cell membrane permeability, diffuse changes in intracellular structures, presence of viral inclusion bodies, and chromosomal aberrations. It excludes malignant transformation, which is CELL TRANSFORMATION, VIRAL. Viral cytopathogenic effects provide a valuable method for identifying and classifying the infecting viruses.

D006517	Murine hepatitis virus	A species of the CORONAVIRUS genus causing hepatitis in mice. Four strains have been identified as MHV 1, MHV 2, MHV 3, and MHV 4 (also known as MHV-JHM, which is neurotropic and causes disseminated encephalomyelitis with demyelination as well as focal liver necrosis).
