The world has lost a true great. 😞

A cell nucleus reconstituted in vitro in Xenopus laevis (African clawed frog) egg extract. Left image shows a fluorescence image where DNA has been stained and right image shows a density map of the same nucleus aquired using Optical Diffraction Tomography (ODT).

Researchers from #MPZPM and @mpiib-berlin.mpg.de have now compared the ratio of nuclear and cytoplasmic density in different organisms and come to a surprising conclusion: the cell nucleus in eukaryotes is less dense than the rest of the cell.

Myeloperoxidase transforms chromatin into neutrophil extracellular traps - Nature Myeloperoxidase, a highly expressed neutrophil protein, disassembles nucleosomes, facilitating neutrophil extracellular trap (NET) formation, and binds stably to NETs extracellularly.

📃 New paper alert!
The Zychlinsky Lab and @raunser-lab.bsky.social identified the first protein that converts chromatin into an immune effector: Myeloperoxidase transforms chromatin into neutrophil extracellular traps. Now published in @nature.com:

📢 Voices in Infection Biology
☀️ We're back from summer break with a talk by Jan Skotheim from @stanford.edu, kindly hosted by @simonereber.bsky.social.

🗓️ Wednesday, September 10
🕓 4 pm
📍 on-site seminar (Berlin)

Event info: www.mpiib-berlin.mpg.de/events/42144...

Patrick's paper is finally out, a label-free method to measure the composition of multicomponent biomolecular condensates!

🚨 Paper alert!
Check out the latest work from the Reber Lab 📌 New research by @simonereber.bsky.social and @biswashere.bsky.social, now published in @natcomms.nature.com 🥳

It's here! It's out! AND It's become better 🐸

Our fundamental work on intracellular density distributions, how it influences cellular organisation & how deviations occur during pathophysiological states like senescence is out in @natcomms.nature.com

Congratulations & thank you to the entire team!

🚨 New paper alert: cytoplasm density controls spindle architecture and size. This shows for the first time that a physical property of the cytoplasm regulates the spindle. Congrats to @simonereber.bsky.social, @tobiaskletter.bsky.social and everyone who contributed.
