What mechanisms drive retraction of the trailing edge?
What mechanisms drive retraction of the trailing edge? Protrusion at the front and retraction at the rear are key force-generating processes at the cell periphery that culminate in the translocation of the cell. For [...]
What are invadopodia?
What are invadopodia? Invadopodia are actin-rich structures that are present at the basal surfaces of cells that are capable of crossing extracellular barriers, such as cancer cells. The primary function of invadopodia appears to [...]
What are the functions of podosomes?
What are the functions of podosomes? Both focal adhesions and podosomes are intimately involved in cell motility, with podosomes specifically implicated in cell invasion. Invasiveness is achieved through the secretion of matrix metalloproteinases (MMPs) [...]
What are podosomes?
What are podosomes? Podosomes are actin-rich, adhesive structures that are present at the ventral surface of cells of the monocytic myeloid lineage, stimulated endothelial cells [1] and cultured Src-transformed cancer cells. These structures are [...]
What are the first steps in invadopodia assembly and disassembly?
What is the first step in invadopodia assembly? Initiation of invadopdia formation is highly complex, being influenced by various signalling cascades and phosphorylation events that occur following detection of a stimulant. For example, activation [...]
How do invadopodia degrade the extracellular matrix?
How do invadopodia degrade the extracellular matrix? The main function attributed to invadopodia is that of extracellular matrix (ECM) degradation, facilitated by the secretion of proteases. Maintenance of this process requires the delivery of [...]

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.
