Fabio Lolicato @fabiololicato.com · Apr 21 Cells vs. reconstitution systems: Asymmetric PI(4,5)P₂ distribution in living cells accelerates FGF2 translocation—something symmetric GUVs can’t replicate. But when we enzymatically introduced asymmetry into GUVs, the magic finally happened 🪄🎩🐇

If our hypothesis holds, disrupting PI(4,5)P₂ asymmetry in cells should slow FGF2 translocation. To test this, @manpreet0700.bsky.social introduced PI(4,5)P₂ micelles in the media—enriching the outer leaflet and disturbing the natural asymmetry. And yes, it made a difference.
