Dynamics of the RNAi-mediated antiviral immunity (RNAiMMUNITY)

Date du début: 1 janv. 2015, Date de fin: 31 déc. 2019,

RNA interference (RNAi) is a conserved sequence-specific, gene-silencing mechanism that is induced by double-stranded RNA (dsRNA). Double-stranded RNA is commonly generated during viral replication and is considered to be a molecular pattern associated with viral infection. Our previous work demonstrated that viral infections in the fruit fly Drosophila melanogaster are countered by an antiviral R ...

Genetics of mosquito resistance to pathogens (AnoPath)

Date du début: 1 mars 2013, Date de fin: 28 févr. 2018,

Malaria parasite infection in humans has been called “the strongest known force for evolutionary selection in the recent history of the human genome”, and I hypothesize that a similar statement may apply to the mosquito vector, which is the definitive host of the malaria parasite. We previously discovered efficient malaria-resistance mechanisms in natural populations of the African malaria vector ...

Dynamic Interplay between Eukaryotic Chromosomes: Impact on Genome Stability (DICIG)

Date du début: 1 juin 2011, Date de fin: 31 mai 2017,

The structure and role of the DNA molecule raise fascinating questions regarding its dynamics, i.e. not only the tri-dimensional reorganisation associated with functional events at short time-scale, but also the structural changes, i.e. rearrangements, that occur in the chromosome over generations. It is increasingly obvious that the physical properties of both the chromosomes and their environmen ...
