Hypothesis
PRRSV infection spreads by cell-to-cell transfer in cultured MARC-145 cells and is dependent on an intact cytoskeleton.
Conclusion
The study shows that PRRSV infection involves primary infection of a small number of cells followed by secondary spread to neighboring cells, highlighting the importance of the cytoskeleton in this process.
Supporting Evidence
- PRRSV infection was shown to spread from a small number of permissive cells to surrounding cells.
- An intact cytoskeleton was found to be critical for both PRRSV infection and transmission.
- Drugs like AK-2 and IFN-γ were effective in suppressing PRRSV infection.
Takeaway
PRRSV can move from one cell to another, and it needs the cell's structure to do this. If we can block this movement, we might be able to stop the virus.
Methodology
Flow cytometric and fluorescence antibody analyses were used to study PRRSV infection dynamics in MARC-145 cells.
