Molecular Cell Biology
The cytoskeleton is responsible for mechanical stabilisation of the cell, for its motility and intracellular transport processes as well as for maintenance and change of its overall shape. The research group Molecular Cell Biology focusses on one specific part of the so called cytoskeleton: the actin cytoskeleton. The dynamics and turnover of filaments of the actin cytoskeleton are particularly relevant for effective immune responses, and are also frequently targeted by pathogens. Understanding the molecular mechanisms mediating assembly and disassembly of this filament system is thus among the main goals of Klemens Rottner and his team.
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.
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.

Neuroinflammation and Neurodegeneration
What kind of role play infections and the associated inflammatory reactions for the progression or even for the onset of neurodegenerative diseases? Recurrent infections and the involved inflammation may trigger a series of processes in the brain that finally lead to neuronal damage due to the immune response. Thus, better understanding of neurodegenerative processes could improve the therapeutic approach in neurodegenerative disease.
Microbial Proteomics
A genome contains all the information that is needed to build an organism like, for instance, a bacterium. One of functional genomics’ central questions is: How are these blueprints implemented so that relatively simple molecular codes ultimately give rise to a microorganism with the potential of getting us sick? What are some of the underlying mechanisms and under what conditions do they become activated?
Microbial Interactions and Processes
Microorganisms in the environment are living in complex and interacting communities. Also the surfaces of the human body are inhabited by microorganisms, where the bacterial cell number significantly exceeds that of the human cells. These communities have co-evolved with the human host and are important for human health. They can, however, also be a reservoir for pathogenic microorganisms.
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.
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.

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.

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.
