| Objective: human cytomegalovirus can infect neonatal mouse's cerebral cortex cells in vitro.Virus which were latency in the mouse's cerebral cortex cells can be reactivated in vivo.Methods:In vitro:Make sure of dose of virus to infect neonatal mouse's cerebral cortex cells by TCID50 .Take HCMV AD169 and three strain HCMV wilds as objects,inactive virus which were deal with high temperature be used control. Virus were put into Balb/c neonatal mouse's cerebral cortex cells and HF cells.Observing HCMV specific CPE by microscope and detecting HCMV specific early gene IE and UL83 by PCR RT-PCR.In the 1 2 3 4 5, we collected cells in the culture of neonatal mouse's cerebral cortex cells with virus. Detecting HCMV special early and later gene and UL83 by PCR RT-PCR indirect immunofluorescent; determining virus titer of cultured supernatantof neonatal mouse's cerebral cortex nerve cells;observing HCMV particles in nerve cells by Electron microscopy. In vivo:Choiced randomly five mice in the modle of human cytomegalovirus congenital latent infection There were three groups: mouse of human cytomegalovirus congenital latent infection,mouse of human cytomegalovirus congenital latent infection be reactivated ,mouse of HF cells. Put the mouse's cerebral cortex cells with HF cells by co-culture and detected HCMV specific early gene IE and UL83 by PCR RT-PCR and HCMV pp65 by indirect immunofluorescent. Observing HCMV particles in nerve cells by Electron microscopy.Result:In the vitro:In the second day,we can find the nerve cells happened shape changes in the culture of neonatal mouse's cerebral cortex nerve cells which were... |
