Recoding Mechanisms in Infections
Many important viruses such as Ebola, Influenza, and HIV use RNA as genetic material. These viruses have an extremely small genome size compared to the eukaryotic host genomes, and therefore employ various alternative translation strategies such as stop codon read through, leaky scanning, non-IRES initiation and ribosome frameshifting to express their genes by the host translation machinery. Interestingly, the same strategies are also used in the host’s cellular gene expression. With our research we aim to understand how translational recoding changes the rules of standard decoding, allows simultaneous encoding of multiple proteins from the same mRNA and regulates gene expression in time and space. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
Drug Design and Optimization
In order to combat the increasing number of resistant pathogens, the development of new anti-infective drugs is an important goal for pharmaceutical research. Efficient medications with novel modes-of-action to fight infectious diseases are urgently needed. Below, you may read more about the design, identification and optimisation of new drug candidates. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Drug Bioinformatics
Bioinformatics is instrumental in all areas of molecular biology, from analysis of genome sequences towards predicting three-dimensional structure of drug-target complexes. We apply cutting-edge bioinformatics and computer science techniques for discovery of novel resistance mechanisms and predicting mode-of-action of bioactive compounds. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS)
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) .
Clinical Bioinformatics
The Department of Clinical Bioinformatics group 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) .
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.
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.
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.
Flow Cytometry and Cell Sorting
Our organism is made of many different cells that are specialized to perform specific tasks. As long as they work together in the collective, we will stay healthy – do they change or are they changed by pathogens, we become unbalanced and sick. The Flow Cytometry and Cell Sorting platform provides the instrumentation and expert knowledge for the phenotypic identification and functional analysis of cells at the single cell level.
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.
