IFIB – Interfakultäres Institut für Biochemie

Gruppen A - F

Dimmer Group – Organelle Biology

Our group focuses on different aspects of mitochondrial function. Especially physical and functional contacts of mitochondria to other organelles, mitochondrial morphogenesis and mitochondrial lipid homeostasis are in the center of our interest.

Dodt group - cell biochemistry

Our work is focused on peroxisomal biogenesis, which includes de novo formation of peroxisomes, peroxisomal protein import, and peroxisomal biogenesis disorders (PBD). Defects in peroxisomal biogenesis can be linked to mutations in so called PEX genes and cause a group of inherited diseases like rhizomelic chondrodysplasia punctata and the different forms of the Zellweger spectrum, which, in severe cases, can be lethal in the first year of life. We use human fibroblasts of PBD patients as model system or in vitro systems and try to elucidate the molecular mechanisms of peroxisomal biogenesis and dynamics by investigating protein interactions, structure, and function of different involved proteins.

  • Peroxisome biogenesis
  • Membrane protein import
  • Matrix protein import
  • Peroxisome maintenance and degradation

Feil group - signal transduction, transgenic models

We study signal transduction in transgenic cell and mouse models by an approach that we call "in vivo biochemistry". To this end, we use state-of-the-art transgenic mouse technology and try to "watch" biochemical processes in real time in living cells, tissues and mice. Specifically, we are interested in the role of the signalling molecule cGMP in health and disease, with a current focus on cell growth and plasticity in the mammalian cardiovascular and nervous system. The projects involve analyses at the whole organism, cellular and molecular level.

Research topics

  • Cardiovascular and neuronal cGMP signaling in health and disease
  • Visualization of cGMP and other signaling molecules with optical imaging (live cell and intravital imaging)
  • Genetic inducible cell fate mapping and cell tracking in animal models of diseases
  • Conditional gene targeting

Filarsky group - biochemistry of cellular systems

In our lab we are fascinated by how the eukaryotic malaria parasite Plasmodium falciparum employs sophisticated networks of interacting proteins and regulatory non-coding RNA molecules to control the organization and expression of its genome. To study these processes, we use a multidisciplinary approach combining genetics, epigenomics, biochemistry and imaging technologies. The ultimate goal of our research is to understand how the parasites can control their cell cycle progression, by translating adaptive signals from their environment into changes of chromatin structure and gene expression. 
To achieve this goal, the biggest asset for our research are postdocs and students. They are the new frontiers and the driving force of innovation and discovery. The vision for my group is therefore, to provide an environment free of barriers—financial, technological, as well as intellectual—where young scientists can develop their ideas, collaborate freely, and learn all the aspects needed for a scientific career.

Research topics

  • How is the expression of lncRNAs controlled?
  • What roles do lncRNAs play in the epigenetic control of gene expression and cell cycle control?
  • What is the molecular machinery governing chromatin dynamics in P. falciparum?
