What are arboviruses?
Arboviruses are viruses transmitted by arthropods, such as mosquitoes and ticks, that can cause diseases in humans and animals.
Why use lepidopteran cells for this study?
Lepidopteran cells have minimal background replication of arboviruses, making them ideal for studying viral replication conditions.
What is the significance of identifying host factors?
Identifying host factors helps understand how viruses evade immune responses and can lead to the development of targeted therapies.
How do fluorescence and luminescence assays work?
These assays measure the light emitted by fluorescent or luminescent markers, providing quantitative data on viral replication.
What are the implications of this research?
The findings can inform future research on viral pathogenesis and the development of antiviral strategies.
