Hypothesis

The study aims to uncover the order of events during reovirus membrane penetration.

Conclusion

The high-resolution structure of the aquareovirus virion reveals a defined order of proteolytic cleavages that prime the virus for membrane penetration.

Supporting Evidence

  • The study provides new insights into the order of entry events for reoviruses.
  • High-resolution cryo-EM allows for the observation of protein sidechains.
  • The aquareovirus ISVP structure is the largest atomic structure solved to date.

Takeaway

Scientists used a special imaging technique to see how a virus enters cells, helping us understand how it works.

Methodology

The study utilized high-resolution cryo-electron microscopy to analyze the structure of the aquareovirus virion.

Limitations

The structures of the reovirus ISVP* and post-penetration forms remain undetermined, leaving gaps in understanding the entry mechanism.
