About the conference

CNET 2019 gathers researchers with interests on topics related to transposable element biology, including molecular, cellular mechanisms, physiological impact on organisms, comparative genomics, population evolution, and ecology.

This is the 22nd annual meeting organized by the French research community working on transposable elements and will take place this year in Lyon, in the Rhone valley of France.

We invite interdisciplinary contributions including molecular, genetics and cellular studies, as well as  bioinformatics and mathematical modelling approaches, applied to a wide range of model organisms (prokaryotes, plants, yeast, insects, ciliates, vertebrates,...). The programme will include invited talks, selected talks and ample time for poster presentation and discussions. Junior researchers are encouraged to apply for oral presentations.

The rapid evolution of small RNA pathways and DNA methylation targeting transposons in arthropods

In the Drosophila germline, small RNA molecules termed PIWI-interacting RNAs (piRNAs) silence transposable elements (TEs), protecting the germline from genomic instability and mutation. In the soma, TEs are silenced by another class of small RNAs called siRNAs. We have found that this difference between the germline and soma is a recent evolutionary quirk of Drosophila, and analysis of 20 species across the arthropod phylum suggests that somatic piRNAs targeting TEs and messenger RNAs are common among arthropods. The presence of an RNA-dependent RNA polymerase in chelicerates (horseshoe crabs, spiders and scorpions) suggests that arthropods originally used a plant-like RNA interference mechanism to silence TEs. In mammals and plants, cytosine methylation plays an important role in silencing TEs. This DNA methylation machinery is missing from Drosophila, but in other arthropods TEs are targeted by methylation.

Living with a million-year long infection

Despite eliciting host immunity, several viruses establish chronic, often life-long infection in humans that can affect immune function. The ultimate form of parasitism and evasion of host immunity is for the virus genome to enter the germ line of the host. Retroviruses have invaded the host germ line on the grandest scale, and this is evident in the extraordinary abundance of endogenous retroelements in the genome of all vertebrate species that have been studied. Recent studies suggests that such viral endogenisation events continue to shape host immunity over long evolutionary times and through diverse mechanisms, including triggering host innate and adaptive immune responses or regulating immune gene expression or function. Although recent integrations may be more detrimental to host immunity, evidence will be presented that integrations acquired millions of years ago were positively selected and continue to shape host immunity in humans.
