Recent achievements

  • Our studies on hepatitis C virus (HCV) assembly have led to the identification of p7 and NS2 HCV non-structural proteins as key determinants governing in concert the subcellular localization of HCV core and required for initiation of the early steps of virus assembly.
  • We revealed a previously unsuspected mechanism of innate immunity in which exosomal export of viral RNA from infected cells serves as a host strategy to induce an innate response in cells whose innate signaling pathways are unopposed because they are not infected.
  • We have invented lentiviral vectors pseudotyped with the glycoproteins from measles virus that allow for the first time robust transduction of resting T and B lymphocytes, which opens numerous applications in the field of cell and gene therapy.
  • Our development of viral-like particle platforms, combining high bio-safety and strong immunogenicity features, has yielded proofs of concept for novel vaccine candidates against HCV and respiratory viruses such as avian influenza viruses and human metapneumovirus.
