🧠 The Lipid
#Brain
Atlas is out now! If you think
#lipids
are boring and membranes are all the same, prepare to be surprised. Led by
@lucafusarbassini.bsky.social
with Giovanni D'Angelo's lab, we mapped membrane lipids in the mouse brain at high resolution.

Lipid imaging on the cover of

🌶️ Lipids bring the heat 🔥 Lipids don’t just shape membranes, they influence cellular metabolism. We show that tuning lipidome composition strongly alters metabolic heat flow in the minimal cell JCVI-Syn3B 🦠 Fantastic collaboration with Karim Fahmy’s lab (HZDR) 🎉

Happy to share our work on uMAIA, a framework for building metabolomic atlases from mass spectrometry imaging. With uMAIA, we mapped the lipidome of zebrafish development, uncovering spatially organized metabolic programs .

Out today in
@nature.com
: Together with the Honigmann, Shevchenko, Drobot and Hof labs, we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism.

Why are biological membranes asymmetric, with different lipids in the two bilayer leaflets? Discovered in the 70s, lipid asymmetry is linked to many cellular processes, but why the cell needs it is largely unclear.
