The actin-spectrin submembrane scaffold restricts endocytosis along proximal axons

F. Wernert, S. B. Moparthi, J. Laine, G. Moulay, F. Boroni-Rueda, F. Pelletier, N. Jullien, S. Benkhelifa-Ziyat, M.-J. Papandreou, C. Leterrier, S. Vassilopoulos

The paper investigates how the actin-spectrin scaffold in axons regulates clathrin-mediated endocytosis, finding that spectrin clearings restrict pit formation and endocytic activity.

Caveolin-1 protects endothelial cells from extensive expansion of transcellular tunnel by stiffening the plasma membrane

C. Morel, E. Lemerle, F.-C. Tsai, T. Obadia, N. Srivastava, M. Marechal, A. Salles, M. Albert, C. Stefani, Y. Benito, F. Vandenesch, C. Lamaze, S. Vassilopoulos, M. Piel, P. Bassereau, , E. Lemichez

This study shows caveolin-1 reduces TEM tunnel size by stiffening the membrane, and its depletion increases TEM number and size, leading to higher lethality in mice during infection.

A mechano-osmotic feedback couples cell volume to the rate of cell deformation

L. Venkova, A. S. Vishen, S. Lembo, N. Srivastava, B. Duchamp, A. Ruppel, S. Vassilopoulos, A. Deslys, J. M. Garcia Arcos, A. Diz-Munoz, m. Balland, J.-F. Joanny, D. Cuvelier, P. Sens, M. Piel

The paper shows that cell volume depends on the rate of deformation, proposing a mechano-osmotic coupling model involving actin cortex and ion fluxes.

Ultrastructure of the axonal periodic scaffold reveals a braid-like organization of actin rings

S. Vassilopoulos, S. Gibaud, A. Jimenez, G. Caillol, C. Leterrier

The paper uses advanced microscopy techniques to reveal the ultrastructure of axonal actin rings, showing they are braided structures composed of intertwined actin filaments and spectrins.
