Description of Research

The main focus of the laboratory is the molecular and cell biology of virus-host interactions. The Group has a long-standing interest in HIV-1 transcriptional and post-transcriptional nuclear regulation and has recently become interested in hepatitis C virus (HCV) and in vector-borne viruses, such as tick-borne encephalitis virus (TBEV) and Zika virus (ZIKV). To this end, the lab has developed a platform of tools for the study of the virus-host crosstalk: from single protein-protein interactions to the 3D dynamics of host and viral components. Great effort has been devoted to the development of techniques that enable the study of virus-host interactions at high resolution and in living cells. During the past few years, the lab, in addition to photobleaching techniques, has developed a unique method to visualize viral RNAs in real time in living cells.
We are also interested in implementing viral diagnostics for developing countries by technically supporting local scientists and by developing point-of-care portable devices in collaboration with industrial partners.
Finally, chemical compounds synthesized in collaborating laboratories are tested for antiviral activity. Related to the group are the following:
