Abstract

Twelve clones derived from the cells persistently infected with the JHM strain (JHMV) of mouse hepatitis virus (MHV) were established from mouse astrocytoma-derived DBT cells and characterized. All the cell clones were resistant to superinfection with MHV. Only one of the persistently infected cell clone synthesized viral RNA and proteins and produced virus particles. Viral RNA was detectable in some other cell clones without production of viral protein nor the virus. No cell clones exhibited contact fusion activity. The results suggested that such variety of cell clones might have resulted from persistent infection with JHMV.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
