10 days before the deadline for this funded PhD opportunity! If you have a bio/neuro/microscopy background and interested in validating new methods, please apply

fabulous work by Christophe Leterrier and Steph Vassilopoulos about exocytosis in between axonal rings. is that the actual function of rings? making sure secretion is reduced along the axon shaft and favoured where it connects to other neurons?

New study out on bioRxiv! We have studied how resources are shared between actin networks competing for a limited pool of components. biorxiv.org/content/10.110…

4. We studied cases in which many beads were in microwells. We first looked at conditions without turnover and saw that when the number of beads increases in the microwell, the size of each structure diminishes.

5. Interestingly, whatever the number of beads in the microwell, there is always the same quantity of actin that is polymerized in comet tails. Thus, without turnover, the actin monomer pool is limiting and the structures share the pool of available monomers equally.

6. We then studied the same situation, in presence of turnover and we saw that the size of the structures has a weak dependence with the number of beads in the microwell.

7. We then looked at structures with various densities in competition for limiting ressources. For that, we prepared "weak" and "strong" beads. Without turnover, when the two beads are in competition in the same microwell , the weak bead never start to grow.

Guerin Alvéole 10. We then demonstrated that when there is turnover, weak structures (from beads or micropatterns) can grow when they are in competition with strong networks. Turnover enables the weakest to exist!

Guerin Alvéole To challenge the limits of the system, we studied conditions with many beads in the microwells. We then looked at the fraction of weak beads moving, as a function of competition strength (defined by the number of strong beads).
