Dengue fever is the most common infectious disease transmitted by mosquitoes – some 100 million people around the world are infected. Researchers at the Hygiene Institute at Heidelberg University Hospital were the first to present a three-dimensional model of the location in the human cell where the virus is reproduced. Their research provides an insight into the exact process of viral replication and serves as a model for other viruses whose replication is still unclear, such as the hepatitis C virus. In addition, it offers new approaches for developing measures to prevent or treat dengue fever. Up to now, neither a vaccine nor a specific antiviral therapy exists.
Professor Dr. Ralf Bartenschlager, director of the Department of Molecular Virology at the Heidelberg Hygiene Institute and his team, working in cooperation with colleagues from the European Molecular Biology Laboratory (EMBL) have published their study in the latest issue of the prestigious journal Cell Host & Microbes.
Viruses do not have a metabolism and cannot produce proteins from their genetic material (RNA or DNA) on their own. They can replicate only inside a host cell – but where and how exactly does this take place? The answer to this question is crucial for developing therapy.
