JC virus (JCV), the causative agent of a human demyelinating disease, progressive multifocal leukoencephalopathy, has a very narrow host range. Cells permissive for infection by JCV have been essentially limited to primary human fetal glial cells, which are difficult to obtain and maintain. In pilot studies, it was found that JCV can multiply in an established cell line of human neuroblastoma. JCV strains Mad‐1 and Tokyo‐1 were inoculated, respectively, into two cell lines, IMR‐32 (neuroblastoma) and A‐172 (glioblastoma). Viral infection with cytopathic effect was observed only in IMR‐32 cells, and the most efficient viral proliferation was obtained in cells cultured in medium containing 2% fetal calf serum (FCS). Both Mad‐1 and Tokyo‐1 strains propagated well, with the former being more efficient than the latter. Viral replication was confirmed by immunofluorescence, electron microscopy, and a hemagglutination assay. Sodium dodecyl sulfate (SDS)‐polyacrylamide gel electrophore‐sis and Western blot analysis of the purified virus revealed the characteristic JCV protein profile. Thus, IMR‐32 cells have been found to be permissive for JCV, which should provide a useful system for further studies of virus proliferation and viral tissue tropism. © 1994 Wiley‐Liss, Inc.
