Structure and development of viruses as observed in the electron microscope. IX. Entry of parainfluenza I (Sendai)
Journal of Virology
|October 1, 1968
Abstract:
After attachment, the uncoating of Sendai virus, which was accompanied by dissolution of the plasma membrane and fusion of virus to cell, proceeded quickly. Nucleoprotein filaments were found at stages of transit from virus to cytoplasm.
Insights
Sendai virus rapidly uncoats after cell attachment through plasma membrane dissolution and fusion. Researchers observed nucleoprotein filaments moving from the virus into the cytoplasm.
Area of Science:
- Virology
- Cell Biology
Background:
- Sendai virus is a paramyxovirus known for its efficient cell entry.
- Understanding viral uncoating is crucial for developing antiviral strategies.
Purpose of the Study:
- To investigate the kinetics and mechanisms of Sendai virus uncoating.
- To identify the initial steps of viral component release into the host cell.
Main Methods:
- Observation of virus-cell interactions using microscopy.
- Analysis of viral component localization post-entry.
Main Results:
- Sendai virus attachment was followed by rapid plasma membrane dissolution and fusion.
- Nucleoprotein filaments were visualized during their transport from the virus to the cytoplasm.
Conclusions:
- Sendai virus uncoating is a rapid process involving membrane fusion.
- Viral nucleoprotein complexes are released into the cytoplasm shortly after entry.
