摘要: During the assembly of vaccinia virus, intracellular mature virus becomes enwrapped by a cellular cisterna to form enveloped (IEV), precursor extracellular (EEV). In this study, we have characterized origin wrapping electron microscopic immunocytochemistry using lectins, antibodies against endocytic organelles, and recombinant viruses expressing proteins which behave as Golgi resident proteins. No labelling for marker could be detected on membrane. However, membrane labelled significantly trans network (TGN) protein. The recycling pathway from endosomes TGN appears greatly increased following infection, since significant amounts fluid-phase tracers were found in lumen TGN, complex, cisternae. Using immunoelectron microscopy, localized VV-p37, VV-p42, VV-p21, VV-hemagglutinin (VV-HA) large cisternae, outer membranes IEV, outermost EEV. bulk VV-p42 whereas VV-HA was also plasma endosomes. Collectively, these data argue that enriched facilitate event responsible formation IEV.
