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.
Molecular Bacteriology
Hospital-acquired infections are a major challenge and cause suffering, incapacity and death. In many cases the pathogens are resistant to antibiotics and, therefore, very difficult to combat. Read more about how bacteria join forces and what the researchers can do to avoid that. The group Molecular Bacteriology is based at the HZI and the TWINCORE in Hannover.
Host-Pathogen-Microbiota Interactions
The importance of RNA in maintaining cellular physiology by controlling gene expression in response to intrinsic and external cues has long been underestimated. Now, numerous human diseases have been linked to RNA functioning. Likewise, we now know that bacterial pathogens harness a large suite of noncoding RNA molecules to adapt to environmental stress and to precisely regulate their virulence programs. In an era of antibiotic crisis, it is essential to discover alternative combat strategies against pathogenic bacteria — ideally ones that spare the beneficial microbial species. The high specificity of RNA molecules provides great potential for achieving these goals. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
Cell Biology
Recent reports published by the World Health Organization (WHO) entitled "The Global Burden of Disease" (GBD) highlights the importance of research on host-pathogen interactions. Evolution is an ongoing process driving the development of highly virulent and multi-resistant bacteria strains or so called “emerging pathogens“. A deeper understanding of the complex interaction between pathogenic bacteria and their host is inevitable to face these problems in the future. As Cell biologists, we address host-pathogen interaction on the level of single cells, embodying the smallest living unit on both sides. Upon contact, pathogens need to manipulate the normal behavior of host cells in order to establish a niche for survival and to evade the hosts defense mechanisms. We study these induced changes on the cellular and molecular level, in order to exactly understand which host process is targeted by a given virulence mechanism an why.
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.
RNA Synthetic Biology
RNA is a ubiquitous molecule of life that plays intimate roles in how cells function and make decisions. These same properties can be harnessed to create a new generation of engineering tools to further interrogate the properties of biology and control how cells behave. The RNA synthetic biology group aims to better understand the roles RNA plays in biology and to exploit these roles to improve how we study, diagnose, and treat infectious diseases in humans. This department is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
Personalised Immunotherapy
Our motivation is to address fundamental questions of human immunology and translate them into personalized therapies and diagnostics. Specifically, our laboratory discovers new applications of antibodies and B cells to treat and prevent human infectious diseases. Effective vaccines against some viruses that escape antibody responses remain elusive. To tackle this challenge, we develop methods to better understand B cell responses, the cells that produce antibodies. We design tailored vaccines and provide novel solutions for infection diagnostics. This Department is located at the Centre for Individualised Infection Medicine ( CiiM ).

Innate Immunity and Infection
The moment a pathogen, which has successfully entered the body, is recognized, the body quickly mobilizes its defenses. Interferons are molecules that are counted among the body’s first line of defense. They prevent proliferation and the spread of viruses in the body and serve to alert the immune system. Read here about the different ways we use to try and decode this system, all in an effort to find new approaches to infectious disease prevention and therapy.
Computational Biology for Infection Research
The Department of “Computational Biology for Infection Research” studies the human microbiome, viral and bacterial pathogens, and human cell lineages within individual patients by analysis of large-scale biological and epidemiological data sets with computational techniques. Focusing on high throughput meta’omics, population genomic and single cell sequencing data, we produce testable hypotheses, such as sets of key sites or relevant genes associated with the presence of a disease, of antibiotic resistance or pathogenic evasion of immune defense. We interact with experimental collaborators to verify our findings and to promote their translation into medical treatment or diagnosis procedures. To achieve its research goals, the department also develops novel algorithms and software.
