Attenuation of virulence in Yersinia pestis across three plague pandemics Yersinia pestis has spilled over from wild rodent reservoirs to commensal rodents and humans, causing three historically recorded pandemics. Depletion in the copy number of the plasmid-encoded virulen...

La peste sait mettre la pédale douce CARTE BLANCHE. Une collaboration internationale a mis le doigt sur une modalité génétique d’atténuation de la virulence commune aux trois pandémies de pestes historiques, explique Alice Lebreton, dans...

Après que la peste a tout dévasté sur son passage, que devient-elle?
Lors de chacune des trois pandémies historiques, un même mécanisme a conduit à la mise en sourdine de sa virulence, ce qui favoriserait sa persistence dans des populations de rongeurs fragmentées.

Sequence-dependent activity and compartmentalization of foreign DNA in a eukaryotic nucleus In eukaryotes, DNA-associated protein complexes coevolve with genomic sequences to orchestrate chromatin folding. We investigate the relationship between DNA sequence and the spontaneous loading and a...

Our latest work: how can compartmentalization emerge in a eukaryotic genome lacking canonical heterochromatin?
By investigating bacterial genomes put in yeast, we show that the presence or absence of transcription is sufficient!

We are very excited to announce a new @events.embl.org conference with a general focus on all infections with the goal to foster discussions across researchers working on multiple pathogens. We couldn't find a conference as such in Europe, so we decided to organize it 😊

Bacteria are so extra. Not only do they produce chemicals to kill their rivals, but some also create metabolites that call in phage reinforcements to finish the job. It's like microbial warfare with backup plans and secret weapons. #CoolBacteria #PhageParty #MicroSky
