What is the role of formin in actin polymerization?
What is the role of formin in actin polymerization? Formins promote the elongation of pre-existing filaments by removing barbed end capping proteins and forming a sleeve around the actin subunits. Formins are also capable [...]
What is the steady state phase of actin polymerization?
What is the steady state phase of actin polymerization? In the steady state phase, the filament dynamics enter a state of equilibrium where monomer disassembly from the (-) end and polymerization at the (+) [...]
What factors influence actin filament length and treadmilling?
What factors influence actin filament length and treadmilling? Several factors influence actin filament length and treadmilling. ATP binding on G-actin and free ATP-G-actin concentration ATP-binding on actin subunits modulates the dynamics of filament assembly, [...]
What factors regulate actin filament polymerization?
What factors regulate actin filament polymerization? Nucleation Promoting Factors (NPFs) (e.g. WASP, Scar/WAVE) modulate actin filament nucleation by bringing together actin monomers and pre-existing actin filaments, for example, during filopodial initiation where they recruit [...]
Actin Crosslinking
Actin Crosslinking Crosslinking of actin filaments is a critical step in cell motility and is a fundamental process in filopodia protrusion and lamellipodia formation. Smaller cross-linking proteins that are more globular (e.g. fascin) [...]
What are microtubules?
What are microtubules? Microtubules are hollow cylinders [1] that are approximately 25nm in diameter [2] and vary in length from 200 nm to 25 μm. They are formed by the lateral association of between [...]

Research Interests
Our research aims at understanding how living organisms interact with their environment. In particular, we are studying the cooperation between adhesion, biomechanical and biochemical signaling for the adaptation of living organisms to changes in their environment. To probe these questions, our laboratory has developed a repertoire of micro- and nano-fabrication tools to control and measure the chemical and mechanical environment of cells. Our research programme thus focuses on the integration of novel microfabricated devices for the quantitative imaging of living organisms.
Biography
With a background in Physics, Prof Ladoux started his career at Curie Institute working on single molecule biophysics. He worked on two main problems combining statistical physics, microfabrication and molecular biology: 1) chromatin condensation in real time; 2) fluctuations of a single polymer under shear flows. After a post-doc on cell mechanics, he used his knowledge in biophysics and microfabrication to start a new subject on mechanical studies of cell migration and adhesion at the University Paris Diderot. He developed microsystems to characterise the mechanical interactions of cells with their migration support. He is currently working on rigidity sensing, collective cell migration and tissue homeostasis.
