✨Excited that the main project of my PhD is now available as a pre-print on #bioRxiv

Here, we used #CryoET to visualise mitochondrial proteostatic stress and together with SPA #CryoEM shed light into the functional cycle of the Hsp60:10 chaperone system. #TeamTomo

Our new preprint is out 🥳🥳🥳

Henipaviruses, like Nipah and Hendra, package their genomes inside helical shells built by thousands of nucleoproteins. These nucleocapsids are essential to protect the viral RNA, but how do they ever let the polymerase in to read the sequence?

Hey #TeamTomo …would you like to try some 🍦ICECREAM!? Our @unibas.ch colleagues over at the @ivandokmanic.bsky.social lab have developed a stunningly effective tool to de-noise and de-wedge your tomograms. The contrast and details will give you brain freeze! 🍨❄️🤯

Please try, we need feedback 🧪🧶🧬🔬

Check out our preprint! With new molecular mechanisms, 140 subtomogram averages, and ~600 annotated cells under different conditions, we @embl.org were able to describe bacterial populations with in-cell #cryoET. And there’s a surprise at the end 🕵️

A molecular-resolution look into the near-native architecture of the spinach chloroplast🌱. This one was a long time in the oven, but we're happy to finally share our "version of record". What long-standing debates did we settle? Check back for a short thread🧵 on Monday. #TeamTomo #PlantScience 🧪🧶🧬🔬🌾
🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture.

In our latest preprint on bioRxiv, we present the in situ structure of
the human gap junction at 14 Å resolution using cryo-ET.

The structure provides a blueprint for investigating how connexin
regulation shapes intercellular communication in health and disease.

Latest preprint from the lab, many years in the making!

By combining #cryoEM with #AlphaFold3 modelling, we propose that norovirus NS3 forms a transmembrane RNA translocase.

This could have big implications for our understanding of viral replication & assembly (🧵)
