New preprint from the lab!

We developed a new tool to identify prokaryotic species (down to the strain level) directly from mass spectrometry-based bottom up proteomics data.

Deltaviruses spread through a viral Trojan Horse Hepatitis D-like satellite viruses, known as deltaviruses, have been recently discovered in a wide range of animals. These viruses are thought to expr…

We found a viral Trojan Horse: a virus can hide inside another virus.This one surprised us: deltaviruses don’t just borrow a helper virus. They can travel inside it.
A literal Trojan Horse “virus-in-a-virus” route into cells. 🤯 Kudos to 1st author @viroscope.bsky.social and co-authors !

Mosquitoes like Aedes aegypti spread viruses that cause major global diseases. We decided to have a closer look at a family of mosquito carbohydrate-binding proteins involved in infecting these vector species. We found some unexpected things 😁

Pre-assembly of biomolecular condensate seeds drives RSV replication Nature - Viral ribonucleoprotein–viral protein networks form pre-replication centres that nucleate viral factories and drive respiratory syncytial virus replication.

Now out in Nature! We visualize infection of the RNA virus RSV in real-time with single-vRNP resolution to understand how RSV establishes viral factories, biomolecular condensates that act as sites of viral replication. A huge collaborative effort led by Dhanushika Ratnayake!

Our paper is finally out!
I’m proud to share this collaborative work using FIB milling and cryo-electron tomography to study tick-borne flavivirus replication. Thanks to all co-authors and collaborators — great teamwork #CryoET #ElectronTomography #Virology #Flavivirus #Microscopy #StructuralBiology

Cryo-electron tomography reveals coupled flavivirus replication, budding and maturation - Nature Communications In this study, Dahmane et al use a method called cryo-electron tomography to uncover new details of how tick-borne flaviviruses transform cells into virus factories.

I am super happy to share this paper in its final form. We used FIB milling to "dig in to" cell lines and mouse brains infected with tick-borne flaviviruses, followed by cryo-ET to study the virus replication. It's open access, so have a look!

Systematic profiling of growth interactions in human gut microbiome species Microbial interactions shape the composition and stability of the human gut microbiome. Yet, the molecular mechanisms underlying these relationships remain poorly understood. Here, we systematically p...

New preprint from the lab is out! 🥳

We systematically profiled all pairwise growth interactions between 36 representative human gut microbiome strains, and delved deeper into the molecular mechanisms behind specific growth interactions.
