Ebola virus VP40 drives the formation of virus-like filamentous particles along with GP.
Using biochemical assays, it has been demonstrated that expression of Ebola virus VP40 alone in mammalian cells induced production of particles with a density similar to that of virions. To determine the morphological properties of these particles, cells expressing VP40 and the particles released from the cells were examined by electron microscopy. VP40 induced budding from the plasma membrane ...
متن کاملCryo-EM near-atomic structure of a dsRNA fungal virus shows ancient structural motifs preserved in the dsRNA viral lineage.
Viruses evolve so rapidly that sequence-based comparison is not suitable for detecting relatedness among distant viruses. Structure-based comparisons suggest that evolution led to a small number of viral classes or lineages that can be grouped by capsid protein (CP) folds. Here, we report that the CP structure of the fungal dsRNA Penicillium chrysogenum virus (PcV) shows the progenitor fold of ...
متن کاملTargeting viral dsRNA for antiviral prophylaxis.
Double-stranded (ds)RNA in the infected cells is a trait shared by most if not all viruses. While humans have developed variable immune responses, viruses have also developed countermeasures to defeat dsRNA-induced antiviral strategies. Thus, we proposed a broad antiviral strategy to antagonize the countermeasures of viruses and bypass the dsRNA-induced signals that are readily defeated by viru...
متن کاملEnhanced light microscopy visualization of virus particles from Zika virus to filamentous ebolaviruses
Light microscopy is a powerful tool in the detection and analysis of parasites, fungi, and prokaryotes, but has been challenging to use for the detection of individual virus particles. Unlabeled virus particles are too small to be visualized using standard visible light microscopy. Characterization of virus particles is typically performed using higher resolution approaches such as electron mic...
متن کاملThe dsRNA of Trichomonas vaginalis is associated with virus-like particles and does not correlate with metronidazole resistance.
Twelve metronidazole-resistant and twelve metronidazole-susceptible strains of Trichomonas vaginalis were tested for the presence of dsRNA. Three resistant and five susceptible strains were found to contain dsRNA which indicated that metronidazole resistance does not correlate with the absence of dsRNA. Electron microscopy showed the homogenates of all dsRNA-positive strains to contain virus-li...
