UPDATE!: I am absolutely stoked that the second paper of my PhD is now out in @natcellbio.nature.com :D. We combined lipid imaging, STED microscopy, and mathematical modelling in a super cool team effort to quantify lipid partitioning inside clathrin-coated pits. www.nature.com/articles/s41....

Lennartz et al. evaluate lipid enrichment in clathrin-coated pits and observe that the differential lipid partitioning into clathrin-coated pits is largely driven by the lipid asymmetry of the plasma ...

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...
