Research interests

I am interested in the structure and function of surface receptors on T cells and accessory cells (macrophages, dendritic cells) to identify novel targets for influencing abnormal and unwanted immune reactions in immunological disorders and diseases. Internationally well recognized are the investigations, which contribute to the understanding of how glycosylphosphatidylinositol (GPI)-anchored receptor proteins transduce signals across the plasma membrane. These studies were fundamental for the identification and characterization of special membrane microdomains, called lipid rafts, which are more and more characterized to control initiation of signal transduction across the plasma membrane of cells. Currently, I am focusing on three main projects: 1) on the signal transduction mechanism of the T cell antigen receptor (TCR), in particular how Lck, the key signalling kinase, is regulated as well as how positive and negative regulating transmembrane accessory molecules control TCR signalling, 2) to characterize human pathological macrophages in autoimmune diseases and to target them for therapeutic corrections by special nanodevices, 3) to develop novel detection platforms for the diagnosis of bacterial infections.

Techniques, methods & infrastructure

Cell culture, multi-parameter flow cytometry, molecular cloning, shRNA silencing, various immunological techniques (isolation, cultivation and stimulation of immune cells, ELISA, immunofluorescence, immunobiochemistry including immunoprecipitation and multiplex immunoblotting, etc), chromatography, advanced imaging (single molecule analysis).  Top-level infrastructure including tissue culture, HPLC, FPLC, various immunodetection systems including ELISAs and Luminex, super-resolution fluorescence microscope for live cell imaging and two advanced flow cytometers able to analyse up to 18 cellular parameters, that are crucial for multicolour and functional analyses of immune cells.
