Oxidative stress in Vero cells infected with vesicular stomatitis virus
Viral-induced apoptosis might be mediated by oxidative stress. It has already been described that cell death in vesicular stomatitis virus (VSV)-infected cells occurs by apoptosis. In this study, oxidative stress parameters present in VSV-infected Vero cells were analyzed. Lipid peroxides (LP) were...
