Abstract
The high incidence of progressive multifocal leukoencephalopathy (PML) in AIDS patients compared with many other immunosuppressive diseases suggests that HIV‐1 infection is strictly related to the activation of JC virus (JCV) propagation. In this report, propagation of PML‐type JCV in COS‐7‐derived cell lines stably expressing HIV‐1 Tat (COS‐tat cells) has been examined. In COS‐tat cells, production of viral particles and replication of genomic DNA were markedly increased compared to COS‐7 cells, as judged by HA and real‐time PCR analyses. These results demonstrate that COS‐tat cells provide a useful model system for studying HIV‐1 Tat‐mediated propagation of PML‐type JCV.
