Uncoupling microtubule lifetime, stability and post-translational modifications.

Tanguy Chocat, Benoît Vianay, Flora Silberzan, Jérémie Gaillard, Louise Bonnemay, Alexandre Schaeffer, Laurent Blanchoin, Manuel Théry

The paper measures microtubule turnover and PTMs in mouse cells, finding that PTMs do not accumulate with age or correlate with stability.

Contractile forces direct the chiral swirling of minimal cell collectives

Ghina Badih, Alexandre Schaeffer, Benoît Vianay, Pauline Smilovici, Laurent Blanchoin, Manuel Théry, Laëtitia Kurzawa

This study shows that contractile forces in endothelial cell pairs determine the direction and strength of chiral swirling in minimal cell collectives.

Centrosome positioning independently of microtubule-based forces

Alexandre Schaeffer, Simona Buracco, Morgan Gazzola, Matthieu Gélin, Benoît Vianay, Chiara De Pascalis, Laurent Blanchoin, Manuel Théry

The paper shows centrosome positioning is driven by actomyosin contractile networks and cell shape remodeling, not microtubule-based forces.
