Hypothesis

COX activity is required for efficient replication of mouse hepatitis virus (MHV) at an early stage of infection.

Conclusion

COX activity is essential for MHV replication, suggesting it could be a target for anti-coronaviral therapy.

Supporting Evidence

  • Blocking COX activity reduced MHV infection by 57% with indomethacin and 95% with curcumine.
  • COX-2 activity was confirmed to be important for MHV replication through RNA interference.
  • Inhibition of COX activity led to a significant decrease in the production of infectious viral progeny.

Takeaway

The study found that certain chemicals that block COX activity can stop a virus from making copies of itself, which could help in treating infections.

Methodology

Caco-2 cells were infected with MHV in the presence of COX inhibitors, and the number of infected cells was measured using immunofluorescence.
