A new in vitro system for the production of the human polyomavirus JC virus (JCV) was established to circumvent the need for virus growth in primary human fetal glial cells (PHFG). The permanent cell line SVG, transformed by an origin-defective mutant of Simian Virus 40 (SV40) was used to grow JCV. JCV-specific RNA could be detected at day 5 and viral antigen at day 6 post infection (p.i.). Virus production peaked at day 16. Virus could be purified by differential centrifugation. The purified fraction consisted mainly of mature particles but contained also pentamers of the major structural virus protein 1 (VP1). The VP1-pentamers could be purified to near homogeneity. The purified virus particles stimulated a specific T-cell proliferation of peripheral blood monocytes (PBMCs) of a patient with progressive multifocal leukoencephalopathy (PML) and of two healthy individuals. In addition, JCV-particles and VP1-pentamers reacted specifically in an ELISA with a series of five PML-patient sera and four sera of individuals not affected by PML. These results demonstrate that purified whole virus particles are suitable for the analysis of specific cellular and humoral immune responses to JCV.
