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.
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.
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.
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.
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)
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.
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.
Genome Architecture and Evolution of RNA Viruses
RNA viruses are a major threat to human health and responsible for millions of deaths each year. Their replication is orchestrated by the RNA genome, which encodes for viral proteins needed to hijack the host cell. Traditionally, infectious disease research has focused on blocking viral replication by inhibiting these proteins. However, we now appreciate that the genomes of RNA viruses are not just passive carriers of protein coding information, but active participants in the viral infection process through the action of non-coding RNA. We study the structure and function of viral non-coding RNA, with the goal of harnessing the resulting knowledge in the design of next generation RNA-based therapies. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI) .
Single-cell Analysis
Pathogenic bacteria can reside in a mammalian host for a life-long period and chronic carriers form a reservoir leading to recurrent infections. Despite the importance of chronic infections for public health, how a subset of pathogens escape the host’s immune surveillance and how the host contains the spread of bacteria are still poorly understood. Scientists within the Single-Cell Analysis group develop and use single-cell transcriptomics and computational approaches to decipher the microenvironments of individual pathogens and ultimately their functional consequences on infection outcome. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
