Computational Biology for Individualised Medicine
Infections are among the biggest threats to health and the most significant causes of death worldwide. Our aim is to reveal the host genetic risk factors and their downstream molecular pathways, which are crucial to make progress in understanding and treating infectious diseases in an individualised manner as well as to improve the identification of patients at risk. The department is part of the developing CiiM and currently housed at the TWINCORE in Hannover.
Experimental Immunology
Immune cell populations are characterized by a high degree of heterogeneity to enable efficient and specialized responses to the diverse set of pathogens. This is particularly true for cells of the adaptive immune system, but also innate immune cell populations are heterogeneous and can adapt to different environmental conditions. Adaptation of immune cells is often associated with epigenetic alterations that lead to the fixation of gene expression patterns, finally resulting in cells with highly specialized fates, phenotypes and functional properties.
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 .
Pathogen Evolution
Ecological interactions that underpin human life are highly dynamic, and changes in complex ecosystems can have far-reaching consequences on human health. Therefore, One Health also has a very strong evolutionary component. Over the last decades, evolutionary biology concepts have provided a major contribution towards unveiling the short- and long-term dynamics of pathogen emergence and spread. The importance of evolutionary approaches has become particularly evident during the COVID-19 pandemic. Both the initial emergence event and the later spread and evolution of SARS-CoV-2 have been investigated using evolutionary genomics – with the rise of variants of concern (VOC) being pointed out in the first place by observational data and inferential statistics. The Department of Pathogen Evolution studies both current and historical samples and uses them to make targeted predictions about the potential spread of important pathogens, thus providing important contributions to public health. The department is located at the Helmholtz Institute for One Health .
Biosafety Level 3 Laboratory
Biological agents of risk group 3 (RG3) pose a constant global as well as national challenge because they cause severe illnesses in humans against which there are usually no effective preventive or treatment measures. Since these pathogens can only be handled in special biosafety level 3 (BSL3) laboratories, the modern BSL3 laboratories at the HZI provide a technology platform that is indispensable in today's infection research - only in this way can our scientists develop new therapies, prevention measures or diagnostic procedures against these pathogens.
Clinical Bioinformatics
The Department “Clinical Bioinformatics” is concerned with analyzing molecular information using computer-based methods such as machine learning, artificial intelligence, or other algorithms. Its focus lies on spatially and temporally resolved processes to help understand how bacteria, as producers of natural products, interact with humans and can trigger or even protect against disease. This department is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Integrative Informatics for Infection Biology
Recent years have seen accelerating development of high-throughput technologies in infection biology. Now, thousands of genetic loci can be simultaneously interrogated in a single experiment, providing an array of measurements of transcription, translation, regulatory interactions, and fitness effects. The bottleneck in advancing our understanding of pathogens now lies in moving from hypothesis-free screening through data integration to hypothesis generation. We develop new statistical, computational, and visualization approaches to overcome this bottleneck in the interpretation of complex post-genomic data. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
Innovative Organoid Research
Organoids are miniature models of human organs cultivated from stem cells in laboratory settings. These delicate tissue structures mimic the three-dimensional architecture and function of real organs, offering researchers a unique opportunity to enhance their understanding of biological processes. Our aim is to advance the development of highly complex organoids incorporating immune cells and vessels. By doing so, we establish a platform, especially for investigating infections, conducting vaccine tests, and innovating therapeutic approaches.
Infection Immunology
An infection can be seen as a fight between a microbe and our body’s defence mechanisms. The microbe is trying to multiply and disseminate, while the different components of our immune system will work together trying to stop this process. This is not an easy mission for our body because microbes have learned how to hide, evade or even destroy some of the components of the immune system as well as how to resist antibiotic treatment. The focus of our research is to understand the battle between microbes and our immune defences. If we know the different tricks and mechanisms employed by the microbes to breach our defences we will be able to design new strategies to counteract and disarm the attacking microorganisms.
Immune Regulation
Due to their physiological functions our mucosal surfaces are in direct contact to the environment and thus represent the major port of entry for pathogens. To protect the body from severe infections an effective mucosal immune system is indispensable. We are studying respiratory tract infections with the focus on influenza and pneumococci, which represent the most frequent viral and bacterial infectious agents for pneumonia in humans. A major focus of our research is to study molecular and cellular processes during coinfection with influenza and pneumococci and here in particular the immunological functions of the alveolar epithelium in host defense.
