Somatic Gene Therapy

We develop new treatment methods for currently incurable disorders. We use and develop techniques for viral and non-viral gene transfer (vectors), which allow to efficiently introduce nucleic acids (DNA, RNA) into body cells. Vector-mediated gene transfer should either help to treat specific diseases (somatic gene therapy) or to prevent them as in the case of infectious diseases (genetic vaccination).

In recent years gene therapy has been very successful in clinical studies not only for several genetic but also for malignant diseases. It can be assumed that these new methods will become very important for the treatment of numerous diseases in the future.

Our current research projects include:

  • Oncolytic viruses for tumor therapy
  • Studying the interaction of viral vectors with cellular and extracellular barriers
  • Production of viral vectors: Adenovirus, Adeno-Associated Virus (AAV)
  • Genetic vaccination
