Excited to share our new paper in @FEBSJournal! With @OndrejKuda & @FedorovaLab we show how LDs reshape the lipidome of PUFA-exposed cells & shift function within the same cell, revealing a context-dependent role in ferroptosis. Congrats Ana & @Lejaperne! shorturl.at/TyRl1

Great to see this Spotlight article in Trends in Cell Biology highlighting our recent identification of a lipid droplet quality control pathway in which FSP1 protects PUFA-rich neutral lipids from peroxidation, thereby suppressing ferroptosis. cell.com/trends/cell-bi…

You do not want to miss the 2026 FASEB #LipidDroplet conference! Abstracts are due May 31. Travel awards are available for trainees 👇

We are looking forward to this presentation by our colleague Dr Duško Lainšček as part of the #symposium we are organising in collaboration with the #CFGBC. Don't miss it Link: cfgbc.mf.uni-lj.si/events/2026cfg…

Thanks to @NatureSMB for publishing a "Research Briefing" on our recent work, highlighting the discoveries and providing context on the story behind our research into how vitamin B2 metabolism regulates FSP1 stability to suppress ferroptosis.

1/3 Thrilled to see our paper led by Kirandeep Deol is out! We used CRISPR screens to uncover regulators of the ferroptosis suppressor FSP1. key discovery: vitamin B2 metabolism stabilizes FSP1 via FAD, revealing a new way vitamins regulate ferroptosis. nature.com/articles/s4159…

"Short-term fasting induces intratumoral accumulation of isoleucine, which reconfigures CD8+ T cell epigenetic programs and phospholipid remodeling, thereby licensing enhanced anti-tumor capacity."

@OlzmannLab Thanks, James!!

Very nice work on lipid droplets, FSP1, and ferroptosis in cancer cells from @PetanLab and colleagues. 👏 🤩

@OlzmannLab @FEBSJournal @OndrejKuda @FedorovaLab @Lejaperne Thank you, James!!
