As part of their investigations, the team led by Professor Michael Schindler, head of the working group at the Institute of Virology, applied the FACS-FRET* technique, which Schindler had developed at the Heinrich Pette Institute in Hamburg. With the aid of FACS-FRET, protein interactions in living cells can be characterized. Furthermore, it allows to unravel the relevance of certain protein interactions for replication. This method also enables screening for antiviral substances.
Finding new antiviral substances with few adverse effects "Our results show how viral proteins interact within human cells. This provides a basis for identifying new antiviral substances. We propose by specifically targeting virus-virus interactions to find drugs with low cellular toxicity. This hypothesis was already confirmed in first screenings approaches," Schindler explains. "Since our method can be applied in an interdisciplinary manner, we are also aiming to elucidate the networks of other human pathogenic viruses. For instance hepatitis B virus (HBV) or the human immunodeficiency virus (HIV)."
Infections with HCV lead to inflammation of the liver, and in up to 80 percent of cases the inflammation becomes chronic. Hepatitis C is a risk factor for the development of liver cirrhosis and liver cancer.
