Main Research Focus
The major aim of our research is the use of medical biotechnology methods including antibody technologies, protein engineering & expression, to develop and evaluate knowledge-based innovative recombinant immunodiagnostics and therapeutics. The main characteristics of these novel agents are: a) disease-specific activities, b) reduced unspecific side effects, and c) reduced immunogenicity. Novel methods for selection of antibodies are developed in close collaboration with a) Dr. Mehmet K. Tur, Experimental Pathology and Immunotherapy, Institute for Pathology, University Hospital Giessen and Marburg, Germany. Novel fusion proteins will be designed using advanced supercomputing tools to model dynamic 1 interactions of proteins, in close collaboration with Prof. Dr. Paolo Carloni, Institute for Advanced Simulation, Forschungszentrum Jülich, Germany. Recombinant fusion proteins are mainly expressed in bacterial or mammalian cells and subsequently characterised in experimental settings, both in vitro on cell lines or primary material of patients and in vivo in transgenic/tumor-bearing mouse models.

This publication is based on a collaboration with Prof Huining He from Tianjin Medical University initially supported by the NRF SA / China Joint Research Programme on "Targeted delivery of siRNAs using recombinant SNAP tag-based antibodies to treat leukemia. The original paper is describing a nanoassembly for targeted delivery of a checkpoint inhibiting siRNA for the treatment of AML. Publications on further results of this highly successful collaboration are in preparation.
