La crosse virus production and export have a colchicine-sensitive step
Cell Biology International Reports
|December 1, 1980
Summary
Colchicine treatment reduced La Crosse virus production and release in infected cells. This suggests a colchicine-sensitive step, potentially involving microtubules, is crucial for virus export.
Area of Science:
- Virology
- Cell Biology
- Microbiology
Background:
- La Crosse virus is a significant human pathogen.
- Understanding virus production and export mechanisms is vital for developing antiviral strategies.
Purpose of the Study:
- To investigate the impact of colchicine on La Crosse virus production and release.
- To identify potential cellular components involved in La Crosse virus export.
Main Methods:
- Infection of cultured cells with La Crosse virus.
- Treatment of infected cells with colchicine.
- Quantification of intracellular and extracellular virus titers.
Main Results:
- Colchicine-treated cells exhibited significantly lower mean virus titers compared to control cells.
- The ratio of released to cell-associated virus was drastically reduced in colchicine-treated cells (1-1.9) versus control cells (13).
Conclusions:
- A colchicine-sensitive cellular process is implicated in La Crosse virus production and/or release.
- Microtubules may play a role in the export of La Crosse virus from infected cells.
