Happy to share our new paper in @febsj.bsky.social! With @ondrej-kuda.bsky.social & @fedorovalab.bsky.social we show how #LipidDroplets reshape the lipidome of PUFA-exposed cells, but can also shift function within the same cell, revealing a context-dependent role in #ferroptosis. shorturl.at/TyRl1

The lipid code to life
Modern lipid biology has evolved far beyond the traditional view of lipids as simple building blocks or energy substrates. Lipids are now recognised as dynamic regulators of biological structures and…

Excited to share my postdoc work @olzmannlab.bsky.social! We found lipid droplets, the cell’s lipid storage depots, are subject to oxidative damage and are protected by FSP1. Loss of FSP1 triggers droplet peroxidation and cell death, revealing a new layer of lipid quality control! shorturl.at/B5XYD

FSP1-mediated lipid droplet quality control prevents neutral lipid peroxidation and ferroptosis - Nature Cell Biology
Lange et al. identify a lipid droplet quality control pathway in which FSP1 safeguards stored neutral lipids from lipid peroxidation, thereby preventing the induction of ferroptosis.

Excited to share our study out in @natcellbio.nature.com! Led by @mikelangelipid.bsky.social, we identify the first #LipidDroplet lipid quality control pathway: LD-localized FSP1 protects stored lipids from oxidative damage and prevents LD-initiated #ferroptosis. www.nature.com/articles/s41...

Happy to finally share my last contribution of my PhD work on protein carbonylation. These diverse and low abundant non-enzymatic PTMs have strong implications in protein structure. Here we show how we managed to consistently detect them in serum of 68 individuals. pubs.acs.org/doi/10.1021/...

Exciting times indeed! With so many new tools entering the field, we can hope to find the answers to many questions in lipid cell biology! Was happy to contribute to this viewpoint.

It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density, which usually isn’t attainable. Lipid-CLEM brought to you by @mathilda95.bsky.social changes that. www.biorxiv.org/content/10.1...
