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! https://t.co/sZlckc7fmt

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.

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.

[James Olzmann @OlzmannLab]

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.

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