Cytoskeletal remodelling and slow dynamics in the living cell

…, B Fabry, M Oliver, DA Weitz, V Viasnoff… - Nature materials, 2005 - nature.com
The cytoskeleton (CSK) is a crowded network of structural proteins that stabilizes cell shape
and drives cell motions. Recent studies on the dynamics of the CSK have established that a …

3D high-and super-resolution imaging using single-objective SPIM

R Galland, G Grenci, A Aravind, V Viasnoff, V Studer… - Nature …, 2015 - nature.com
Single-objective selective-plane illumination microscopy (soSPIM) is achieved with
micromirrored cavities combined with a laser beam–steering unit installed on a standard inverted …

A mechano-signalling network linking microtubules, myosin IIA filaments and integrin-based adhesions

…, Z Zhang, S Shi, M Natarajan, V Viasnoff… - Nature materials, 2019 - nature.com
The interrelationship between microtubules and the actin cytoskeleton in mechanoregulation
of integrin-mediated adhesions is poorly understood. Here, we show that the effects of …

Plasma membrane tension orchestrates membrane trafficking, cytoskeletal remodeling, and biochemical signaling during phagocytosis

TA Masters, B Pontes, V Viasnoff… - Proceedings of the …, 2013 - National Acad Sciences
Phagocytes clear the body of undesirable particles such as infectious agents and debris. To
extend pseudopods over the surface of targeted particles during engulfment, cells must …

Biomimetic emulsions reveal the effect of mechanical forces on cell–cell adhesion

LL Pontani, I Jorjadze, V Viasnoff… - Proceedings of the …, 2012 - National Acad Sciences
Cell–cell contacts in tissues are continuously subject to mechanical forces due to homeostatic
pressure and active cytoskeleton dynamics. In the process of cellular adhesion, the …

Rectification of the current in α-hemolysin pore depends on the cation type: the alkali series probed by molecular dynamics simulations and experiments

…, U Bockelmann, A Aksimentiev, V Viasnoff - The Journal of …, 2011 - ACS Publications
A striking feature of the α-hemolysin channela prime candidate for biotechnological
applicationsis the dependence of its ionic conductance on the magnitude and direction of the …

Extracellular matrix scaffolding guides lumen elongation by inducing anisotropic intercellular mechanical tension

…, K Herr, M Mercade, JP Thiery, H Yu, V Viasnoff - Nature cell …, 2016 - nature.com
The de novo formation of secretory lumens plays an important role during organogenesis. It
involves the establishment of a cellular apical pole 1 and the elongation of luminal cavities 2 …

[PDF][PDF] Unzipping DNA with optical tweezers: high sequence sensitivity and force flips

…, P Thomen, B Essevaz-Roulet, V Viasnoff… - Biophysical journal, 2002 - cell.com
Force measurements are performed on single DNA molecules with an optical trapping
interferometer that combines subpiconewton force resolution and millisecond time resolution. A …

[HTML][HTML] Nanopore unzipping of individual DNA hairpin molecules

J Mathé, H Visram, V Viasnoff, Y Rabin, A Meller - Biophysical Journal, 2004 - cell.com
We have used the nanometer scale α-Hemolysin pore to study the unzipping kinetics of
individual DNA hairpins under constant force or constant loading rate. Using a dynamic voltage …

Rejuvenation and overaging in a colloidal glass under shear

V Viasnoff, F Lequeux - Physical Review Letters, 2002 - APS
We report the modifications of the microscopic dynamics of a colloidal glass submitted to
shear. We use multispeckle diffusing wave spectroscopy to monitor the evolution of the …
