Evolutionary Community Ecology
Humans are increasingly part of these interaction networks and pathogen transmission from animals to humans is occurring at increasing rates. Indeed, emerging zoonotic disease are an increasing threat to human health and most of these diseases have their origins in wildlife. Microorganisms and their associated diseases also influence animal populations’ persistence and conservation, with some spilling over to animals from humans as well. The research group ‘evolutionary community ecology’ explores how the changing composition of animal communities has cascading impacts on their microbial communities, diseases, and rates of transmission, including to humans. The department is located at the Helmholtz Institute for One Health .
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) .
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.
Human-Microbe Systems Bioinformatics
The human body encompasses fewer human cells than microbes. They constantly interact with each other and the host and greatly affect an individual's health and well-being. In our group, we develop and apply state-of-the-art bioinformatics software to study the human-microbe systems and aim to discover natural products involved in communication between the two realms. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Genome Analytics
The Genome Analytics (GMAK) facility provides next-generation sequencing (NGS) technology to the HZI. External users may also have access to the technology, e.g. upon collaborative arrangements. In addition to sample DNA/RNA quality check, library preparation and sequencing, the facility provides primary data processing, data quality check and analysis. A number of pipelines for secondary data processing are established.
Microbial Natural Products
Even today efficient drugs against many diseases are missing but finding new active substances is very complex. Support comes out of the ground. Myxobacteria are soil-living microorganisms that produce many active agents. Here you learn more about the search for new compounds with biological activity. This department is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Neuroinflammation and Neurodegeneration
What kind of role play infections and the associated inflammatory reactions for the progression or even for the onset of neurodegenerative diseases? Recurrent infections and the involved inflammation may trigger a series of processes in the brain that finally lead to neuronal damage due to the immune response. Thus, better understanding of neurodegenerative processes could improve the therapeutic approach in neurodegenerative disease.
Vaccinology and Applied Microbiology
Vaccination is the most efficient strategy to prevent infectious diseases. The art of the vaccine researcher lies in finding substances that prevent us from falling ill with diseases such as influenza or viral hepatitis. But what makes a vaccine successful and ensures effective protection? Our scientists study the reaction of the immune system to answer that question – and to develop better vaccination strategies.
Laboratory of Transmission Immunology
Transmission of viruses is only possible during a specific time frame after infection: we can call this the “window of transmission”. A major gap in mitigating (e.g., airborne) transmission and closing this window quickly is the lack of understanding of critical immune determinants of efficient transmission. To be able to close the window of transmission through the design of better mitigation strategies, we develop a mechanistic understanding of the spatial and longitudinal interplay between virus tropism, innate and adaptive immune responses, changes in host physiology, and exhalation or shedding of infectious virus in droplets or fluids.
Systems Immunology
To see the immune system with the eyes of mathematics – that is the guiding principle of the department Systems Immunology. Mathematical models help to faster and better understand diseases that are associated with immune functions. Read here how scientists use mathematics to investigate chronic inflammatory diseases, the regulation of adaptive immune responses, and the interaction between the nervous, the endocrine and the immune system.
