Experimental Virology
Viruses are tiny vehicles that transport biological information to reprogram the functions of human, animal, or plant cells in order to replicate. So-called "enveloped" viruses consist of only one layer of proteins, are filled with genetic material, and are surrounded by a thin shell of lipids in which viral proteins are embedded. Even though viruses are tiny and have a simple build, viral pathogens such as the hepatitis C virus (HCV), respiratory syncytial virus (RSV), and SARS-CoV-2 have the potential to threaten the health of millions of people. Here at the Institute for Experimental Virology, we focus on fundamental and translational RNA virus research. Our research groups combine the expertise of molecular and cell biological approaches with computational methods to help elucidate viral replication mechanisms to develop new therapeutic and preventive strategies.
Experimental Infection Research
If we are attacked by a virus, the immune system reacts within a matter of hours. Highly specialized immune cells recognise the pathogen and release highly efficient messengers, which activate the immune system. These messengers include the interferons, which ensure that individual host cells are mildly infected . At the same time, interferons can also influence the course of the immune response and the memory of the immune system. Without these messengers virus infections - which we normally overcome almost unnoticeably - become fatal within just a few days. The group Experimental Infection Research is based at the TWINCORE in Hannover.
Genome Architecture and Evolution of RNA Viruses
RNA viruses are a major threat to human health and responsible for millions of deaths each year. Their replication is orchestrated by the RNA genome, which encodes for viral proteins needed to hijack the host cell. Traditionally, infectious disease research has focused on blocking viral replication by inhibiting these proteins. However, we now appreciate that the genomes of RNA viruses are not just passive carriers of protein coding information, but active participants in the viral infection process through the action of non-coding RNA. We study the structure and function of viral non-coding RNA, with the goal of harnessing the resulting knowledge in the design of next generation RNA-based therapies. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI) .
Genome Mining for Secondary Metabolites
The misuse of antibiotics on a global scale has led to an ever-growing antibiotic resistance crisis. Novel antimicrobial compounds are urgently needed. Microorganisms are considered to be one of the most prolific sources for natural product drugs including antibiotics. Developing novel genome mining approaches to harness the potential of the underexplored biosynthetic gene pathways and discover novel microbial natural products, is a potential antibiotic resistance crisis mitigation path. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
