Structural Infection Biology
To understand and eventually manipulate pathways that control the interaction of pathogens (e.g. bacteria, virus, parasite) with their hosts (e.g. human, plants) requires an interdisciplinary research approach, which often combines different fields of research such as cell biology and microbiology. In our laboratory, however, we take a closer look at the processes occurring during an infection at the cellular and atomic level by harnessing a variety of modern biophysical methods that allow addressing the spatio-temporal dynamics of an infectious disease at a high resolution. The department is located at the Center for Structural Systems Biology ( CSSB ) at the heart of the Germany’s largest accelerator center DESY (Deutsches Elektronen-Synchrotron) in Hamburg.
Virology and Innate Immunity
Pathogens (germs) infiltrate our bodies daily but do not remain undetected. They encounter the strong defenses of our immune system, which recognizes invaders and promptly takes appropriate measures. However, many pathogens can produce life-long infections even with an intact immune system. The herpesvirus family is one such group of pathogens. Upon infection, herpesviruses establish a chronic infection and become lifelong companions.
Viral Immunology
“Back then, I wasn’t ill so often”: With advancing age not only the skin loses its elasticity – many organs lose their functions. So does the immune system: Defense cells do not react promptly anymore, and immunological memory is not established. As a result, we are poorly protected by vaccines and more susceptible to infections, but at the same time suffer from inflammatory disease. While the mechanisms of immune aging remain unknown, chronic viral infections are environmental factors that may accelerate the age-related changes of the immune system. Read more about how pathogens may have an impact on the real age of our immune system.
Synthetic biology of microbial natural products
The Bozhüyük group focuses on bacterial natural products, with unique structures and bioactive properties. The group studies modular assembly lines like polyketide synthases (PKSs) and non-ribosomal peptide synthetases (NRPSs), which produce many essential clinical agents – but are especially valuable to develop new anti-infectives. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Structure and Function of Proteins
Structural biology is a powerful method to derive an understanding of the molecular basis of biological phenomena by visualizing the involved biomacromolecules at atomic resolution. The Department Structure and Function of Proteins uses protein crystallography to investigate proteins that play a role in infectious disease, e.g. by controlling the production of toxic molecules or by acting as toxins themselves. Our research in structural biology is complemented by biochemical and biophysical methods, and we employ all of these technologies to also aid drug discovery projects at the HZI.
Cellular Proteome Research
Pathogenic bacteria and viruses utilize and manipulate cellular processes of our immune system. The identification of protein functions in the human immune system that decisively control the progression of infections constitutes the central aim of the research group Cellular Proteomics at the HZI.

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.
Central Facility for Microscopy
Light microscopy and electron microscopy are excellent high resolution tools to investigate the adhesion and invasion mechanisms of pathogenic bacteria. High resolution electron microscopy permits to examine and unravel pathogenicity mechanisms on a morphological basis. ZEIM offers equipment and highly sophisticated expertise for the preparation and observation of biological samples.
