Aging may feel gradual… but what if it’s not?
In our recent paper, we tracked fish continuously from puberty until death.
This gave us a unique view of how aging unfolds across the adult lifespan.

Ups we did it again! Please mark your calender. EMBO Workshop “Lipid Code to Life”, taking place September 7–11, 2026, in Dresden, organized by Maria Fedorova, @lipid.bsky.social, Valerie O'Donnell, @holthuislab.bsky.social and @molcellbiophys-lab.bsky.social 🥳 Retweets = lipidlove

Lipid droplet growth is orchestrated by the seipin complex, which provides a structural platform for droplet nucleation and expansion. The microprotein adipogenin fine-tunes seipin’s conformation, remodeling its architecture to regulate lipid storage capacity. This modulation results in the formation of fewer but larger lipid droplets, revealing a key mechanism in lipid homeostasis.

Fat storage in the body relies on specialized structures called lipid droplets. In a new Science study, researchers identified the microprotein adipogenin as a regulator of adipocyte lipid droplet size, revealing a key mechanism in lipid homeostasis.

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 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!
