Molecular Principles of RNA Phages
The research group led by Jens Hör investigates the dynamics of infection, host takeover, and anti-phage defense during the interaction between RNA phages and their hosts. They seek to understand the molecular principles underlying these processes to develop new and improved antibacterial strategies such as phage therapy.
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.
Core Facility of Comparative Medicine
To be able to investigate diseases, understand the relationships between pathogens and their host and to develop novel strategies against pathogens, the scientists at the HZI depend on experiments that involve the use of laboratory animals. For this purpose, the HZI operates a central animal facility on campus. The primary task of this service unit is the breeding and keeping of laboratory mice as well as provision of services for the scientists of the HZI, centered around laboratory animal science.
Transgenic Mice
Genetically modified mice can provide information about the function of particular genes or individual genetic elements. Further, they can be specifically designed to mimic certain physiologic or pathologic conditions. The Service Unit "Transgenic Mice" (TGSM) creates such genetically modified mice for researchers of the center.
Recombinant Protein Expression
Proteins play an important role in infectious diseases. They not only take over central functions in the invasion and replication of pathogens, but also in the defensive reaction of our body or as a drug. For a detailed investigation of proteins, scientists often require them in large amounts and extremely pure state. Read more about how proteins are artificially produced and purified.
Proteome Analytics
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.
Microbial Drugs
The majority of the medically important antibiotic drugs are derived from secondary metabolites, which are produced by bacteria and filamentous fungi. Despite intensive world-wide efforts using alternative approaches, no other concept could so far surpass the historically successful strategy to exploit biologically active natural products as candidates for anti-infective drugs. The recently observed, increasing resistance of the human pathogens against antibiotics has prompted us to intensify our search for novel lead structures from microorganisms and fungi, which can be used as anti-infective drugs.
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.
Biostatistics
High-Throughput-technologies generate large amounts of data. The drawback: these biological and medical data must be processed to results with statistical methods and models. Concepts from robust and computational statistics as well as visualisation techniques help to better understand, estimate and cope with the uncertainty and strong variation that are often inherent in biological and medical data. The project group „Biostatistics“ is part of the research group „Cellular Proteome Research” which is led by Lothar Jänsch.
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 .
