Group leader at @imbmainz. Excited to study how lipids regulate aging and longevity. Opinions/views are my own. papsdorflab.com

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. 🧵

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. Learn more this week: https://scim.ag/4nFEGO7

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.

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.

Thrilled to see this paper out!! 🧪 Spatial transcriptomics of brain aging and 'spatial aging clocks' identify cells that have pro-aging or pro-rejuvenating effects on their neighbors! Huge CONGRATS to Eric Sun and all authors! Fantastic collaboration with @jameszou.bsky.social! rdcu.be/d33uQ 🧵
