Hypothesis
The nuclear localization signal (NLS) of capsid protein between PCV1 and PCV2 is functionally exchangeable and affects viral replication.
Conclusion
The nuclear localization signal sequence of capsid protein is functionally exchangeable between PCV1 and PCV2, but it plays an accessory role in viral replication.
Supporting Evidence
- The study confirmed that the DNA clones were infectious in vitro.
- Infectious titers of chimeric viruses were significantly lower than wild type viruses.
- The nuclear localization signal sequence was shown to be functionally exchangeable.
Takeaway
This study found that parts of the virus that help it get into cells can be swapped between two types of viruses, but this doesn't change how well they grow.
Methodology
The study involved constructing DNA clones of PCV1 and PCV2, transfecting them into PK-15 cells, and evaluating their infectivity and growth characteristics.
Limitations
Further studies are required to determine the in vivo viral replication and pathogenicity of the NLS chimeric DNA clones.
