Abstract

In this report, the role of nitric oxide synthase (NOS) and IL-12 administration in inhibition of vesicular stomatitis virus (VSV) from infected neuroblastoma cells was examined. We previously have shown that cytokine treatment of cells results in the induction of NOS-1, and this is associated with a 2 log inhibition of VSV production. We performed these studies to examine the mechanism by which viral replication is suppressed. Neuroblastoma cells (NB41A3) were treated with either IL-12 or medium and subsequently infected with VSV. Viral protein and mRNA were isolated from these cells, and their levels were measured by Western or Northern blots, respectively, mRNA levels were decreased modestly, but viral proteins were decreased substantially in cells pretreated with IL-12, suggesting that the inhibitory effect of NO is working at the translational level. Cytokine treatment of cells was not associated with oxidative stress. The vital proteins also were nitrosylated. These data suggest that the mechanism of NO inhibition of vital replication occurs through translational interference and posttranslational modifications of viral components.
