Prof. Dr. Winfried Römer

Field of research

The Römer lab is mainly focused on host-pathogen interactions; in particular, we are interested in understanding the impact of bacterial lectins on host cell physiology in single cells, tissues and model organisms in molecular detail by using a combination of analytical and synthetic approaches. For instance, we investigate the effects of the P. aeruginosa lectins LecA and LecB on wound healing processes (e.g. cell adhesion and migration, and cell proliferation). Moreover, based on principal findings we develop alternative strategies to fight bacterial infections, e.g. divalent lectin inhibitors that fully block host cell invasion when applied in nano-molar concentrations.The Rising Star could study the impact of the P. aeruginosa lectins on integrin signaling and cytoskeleton dynamics.
