RNAi is a mechanism explaining the production of small RNAs of about twenty one nucleotides derived from the virus, which are then used as guides for targeting very specifically a RNase from the Argonaute family to the viral RNAs, which will be neutralized selectively. We are interested in understanding three main points during viral infection:
How viruses are recognized by the exonuclease Dicer-2?
What are the antiviral complexes in opposite to RNAi pathway?
What are the dynamics of the antiviral innate immunity?
The team is composed of a permanent member from the University of Strasbourg (Carine Meignin, associate professor), working with post-doctoral fellows and technicians supported by grants, PhD and Master students.
In addition, since 2012, a collaboration with the group of J. Marques in Belo-Horizonte (Brazil) allows to extend the work on flies to Aedes vector mosquitoes, which transmit viruses such as Dengue or Chikungunya to humans.
