Giannone Lab

Studying the forces and the dynamics behind cell motility and adhesion. We dabble a lot with super-resolution microscopy and single particle tracking.

Here is a Share Link to our recent review @TrendsCellBio focusing on Novel imaging methods and force probes for molecular mechanobiology of cytoskeleton and adhesion. Nice to share beautiful studies from wonderful labs. https://t.co/bdQ59Q3a9R

The @GiannoneLab and the Nassoy Lab have open positions for postdocs at the University of Bordeaux. The goal of the project is to understand at the molecular level integrin adhesions and actin protrusions in cancer cells migrating in 3D cellular assemblies: organoids, spheroids.

11/n - Our results thus indicate that forces exerted by elongation of individual actin filaments on WRC increase its turnover, operating as a mechanical negative feedback on Arp2/3 activation and thus cell migration.

Read the full article https://t.co/v5GINA63LD of our new study @NatureCellBio showing how forces generated by actin filaments regulate the WAVE complex to control new actin generation at the leading edge of migrating cells. Check out the following thread as a summary:

10/n – WRC crosslinking, using the extracellular handle, reduces the ability of actin elongation forces to remove WRC from the lamellipodium tip, resulting in an increased WRC dwell time and higher Arp2/3 activity, enhanced polymerization and more effective migration.

Please check out our recent study @NatureCellBio. Using single protein tracking and optical tweezers to show that actin elongation forces control actin regulator dynamics and functions at the leading edge of membrane protrusions during cell migration.
