Great new study from Veijo! Using cryoET, cell biology and molecular dynamics simulations to show how seipin switches from a closed to an open conformation that defines the ER–lipid droplet connection and drives lipid droplet growth.

How does a cell remodel the ER membrane into a lipid droplet? Excited to share our new bioRxiv preprint, where we find that regulated opening of the seipin ring defines a functional ER–lipid droplet interface — and identify SMLR1 as a regulator of this transition. www.biorxiv.org/content/10.6...

Combining proteomics, structure prediction, bioinformatics and cryoET to discover non-canonical bacterial protein translocation-folding complex doi.org/10.1101/2025...

Excited to share that as my group launches across Karolinska Institutet and the University of Helsinki, we’re recruiting postdocs and research assistants to study the nanoscale architecture of lipid flux using in-cell structural biology approaches, including cryo-ET and cryo-CLEM

In another inspiring talk at #EMBOComp3D, Julia Mahamid spoke about recent in-cell cryo-ET results www.biorxiv.org/content/10.1...

Tired of knowing what you are looking for in your tomograms? Why not try bluesky-less Frosina's new self-supervised algorithm for semantic segmentation and particle picking for #teamtomo (includes a new denoiser without the need for odd/even tomos) Code is on GitHub if you want to try it out

Missed this at the time, super cool. Domes & capsules everywhere it seems..

Thanks! The dome is definitely intriguing, and happily I can point you to this nice recent preprint by my colleague @rasmusjensen.bsky.social about that exactly www.biorxiv.org/content/10.1...

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 🕵️ www.biorxiv.org/content/10.1... #teamtomo

Repost appreciated: Open #PhDposition in structural virology in my group! Join us in Umeå, Sweden to uncover how arboviruses remodel infected cells. In situ #cryoET and #cryoEM combined with #virology, #cellbiology, and #biophysics. Deadline 7 September. More info: www.carlsonlab.se/join/

Very nice and generous summary of our recent preprint by @ewanbirney.bsky.social #cryoem #cryoet #proteinfolding #translocation

This is just an excellent preprint by Rasmus Jensen and colleagues from Julia Mahamid's lab @embl.org - a tour de force of Cryogenic electron tomography to do in cell structural biology in which they discover a new complex and solve its structure and function! www.biorxiv.org/content/10.1...
