Research Topics

Cell adhesion receptors play an essential role for multicellular organisms. Members of different protein families such as integrins and immunoglobulin superfamily cell adhesion molecules (IgCAMs) not only support the structural integrity of cells and tissues, but also contribute to signal transduction. We are interested in elucidating the role of these receptors and their associated signalling enzymes in physiological processes such as cell adhesion and migration, but also aim at understanding the role of these proteins in disease settings involving wound healing, tumor cell survival and metastasis, as well as inflammation.

Cell adhesion receptors are also prime targets for bacterial pathogens trying to establish tight contact with host tissues. Therefore, we are currently analyzing selected human pathogenic microbes with regard to adhesin-receptor interactions and their role in the course of infection.

Supported by tight collaborations with chemists and molecular biologists alike we utilize a wide spectrum of methodological approaches ranging from genetic manipulation of bacterial and mammalian cells, advanced light and electron microscopy, flow cytometry and protein biochemistry to sophisticated spectrometrical techniques such as FLIM-FRET measurements, screening and chemical optimization of small compounds, as well as rational design of synthetic nucleotide analogues for enzyme analysis.

It is our ultimate goal to attain a deepened molecular understanding of cell adhesion receptors and to open up new avenues for modulating their contribution to pathological processes.
