Olivier Duss

Travel’s got me wiped, but catching up with @colindascheele.bsky.social, @pierresantucci.bsky.social & @olivierduss.bsky.social at #FEBS2025 made it totally worth it. Huge thanks to Pelin Telkoparan and Dilek Cevik for the wonderful hospitality—what a time in Istanbul!

Molecular basis of influenza ribonucleoprotein complex assembly and processive RNA synthesis Influenza viruses replicate and transcribe their genome in the context of a conserved ribonucleoprotein (RNP) complex. By integrating cryo–electron microscopy single-particle analysis and cryo–electro...

Excited to share our new @science.org paper! Led by postdocs Ruchao Peng and Xin Xu, we used cryo-EM/ET to reveal the influenza ribonucleoprotein complex structure and its strand-sliding mechanism for RNA synthesis, paving the way for new antivirals.

Single-molecule multimodal timing of in vivo mRNA synthesis mRNA synthesis requires extensive pre-mRNA maturation, the organisation of which remains unclear. Here, we directly sequence pre-mRNA without metabolic labelling or amplification to resolve transcript...

The timeline of co-transcriptional #mRNA processing and #modification may have to be revised: cleavage, termination, and #m6A deposition may occur earlier than most #splicing! Potential textbook changing study in bioRxiv by edueyras.bsky.social & Rippei Hayashi labs!

Novel color via stimulation of individual photoreceptors at population scale Image display by cell-by-cell retina stimulation, enabling colors impossible to see under natural viewing.

Five people have seen a color never before visible to the naked human eye, thanks to a new retinal stimulation technique called Oz.

Thanks a lot for hosting me! Was very cool to talk to all of you!

Check out our preprint at BioRxiv revealing mechanisms of mRNP assembly during translation repression: (www.biorxiv.org/content/10.1...). Great collaboration with Olivier Duss (@olivierduss.bsky.social). Great Work Marco Payr (@marcopayr.bsky.social) and thanks for the video, explaining our paper.

Ever wondered how several individual RBPs cooperate to repress translation?

Lead by @marcopayr.bsky.social and in great collaboration with @hennig-lab.bsky.social, we simultaneously tracked the binding of several proteins to single mRNA molecules in real-time!

Snapshot of in-cell protein contact sites reveals new host factors and hijacking of paraspeckles during influenza A virus infection Influenza A virus (IAV) exploits the host cellular machinery to facilitate its replication, yet many host-IAV interactions remain unexplored in the cellular context. Detailed information about interac...

Great work led by our PhD student Iuliia Kotova in collaboration with Fan Liu @fan-liu.bsky.social, Boris Bogdanow, Lars Mühlberg, and Olivier Duss @olivierduss.bsky.social and Guelsah Gabriel labs. Structural analysis by our PhD student Konstantin Gilep.

A subcellular map of translational machinery composition and regulation at the single-molecule level Millions of ribosomes are packed within mammalian cells, yet we lack tools to visualize them in toto and characterize their subcellular composition. In this study, we present ribosome expansion micros...

Tour de force by Barna Lab

The RNA helicase HrpA rescues collided ribosomes in E. coli Antibiotics that inhibit ribosomes lead to collisions on mRNAs when upstream ribosomes catch up with stalled ones. Campbell et al. show that the HrpA protein in E. coli senses ribosome collisions and removes the stalled ribosome, helping cells survive in…
