The results showed that this cell death is apoptosis.It was found that Vero cells infected with poliovirus died faster than Vero35 cells,in which the apoptosis inhibiting gene p35 of baculovirus can expess stably.The result suggested that poliovirus could induce ICE like mediated pathway of cell death. 脊髓灰质炎病毒 Vero细胞 感染 细胞凋亡 p35基因 poliovirus Vero cells infection apoptosis P35 gene R373.22 国家教委博士点基金 1997-06-01 2021-04-01 6
