Research interests

My research interest is the study of autoantibodies in myasthenia gravis. Myasthenia gravis is an autoimmune disease of the neuromuscular junction. In my previous work I focussed on the pathogenic mechanisms of MuSK autoantibodies of the IgG4 subclass, which block interaction between key signalling molecules at the muscle side of the neuromuscular junction, and the relevance of Fab-arm exchange for this process.  My ongoing research interest is the discovery of novel autoantibodies that cause myasthenia gravis or autoimmune myositis and the development of new diagnostic assays.

To this end I was awarded with a Herta-Firnberg Postdoctoral Fellowship by the Austrian Science Fund.

Techniques, methods & infrastructure

Tissue- and cell-based assays as well as primary cell cultures are used to screen patient serum for the presence of autoantibodies against the neuromuscular junction. Immunoprecipitation and mass spectrometry are then used to identify the precise antigenic target of the antibodies.
