mortality/aging
• in polivirus-infected mice at low doses
• however, high doses provides the same lethality as in Tg(PVR)1Kkst mice
|
immune system
• following injection of high poliovirus titers, mice fail to exhibit an increase in serum IFN-alpha Tg(PVR)1Kkst mice
|
• mice infected with low doses of poliovirus exhibit increased organ titers, reduced lethality and fail to exhibit an increase in IFN-alpha serum levels compared with Tg(PVR)1Kkst mice
• mouse embryonic fibroblasts are more susceptible to poliovirus-induced cell death compared with cells from Tg(PVR)1Kkst mice
