What is caveolar endocytosis?
What is caveolar endocytosis? Caveolar endocytosis is a clathrin-independent endocytic process which involves bulb-shaped, 50-60nm plasma membrane invaginations called caveolae (or ‘little caves’). Caveolae formation is driven by integral membrane proteins called caveolins as [...]
What is clathrin-mediated endocytosis?
What is clathrin-mediated endocytosis? Clathrin-mediated endocytosis (CME) is a vesicular transport event that facilitates the internalization and recycling of receptors engaged in a variety of processes, including signal transduction (G-protein and tyrosine kinase receptors), [...]
How is clathrin recruited to the plasma membrane?
How is clathrin recruited to the plasma membrane? Clathrin-mediated endocytosis is triggered by phosphatidylinositol-4,5-bisphosphate (PIP2) accumulation within the plasma membrane. PIP2 accumulates as a result of phosphoinositide catalysis by the lipid kinases, phosphatidylinositol-4-kinase (PI4K) [...]
How does the clathrin coated pit form?
How does the clathrin coated pit form? Adaptor proteins such as AP-2, AP180 and CALM (Clathrin-assembly lymphoid myeloid leukaemia protein), which accumulate within the lipid bilayer, are responsible for the recruitment of the triskelion [...]
How does invagination and maturation of the clathrin-coated vesicle occur?
How does invagination and maturation of the clathrin-coated vesicle occur? Clathrin-coated vesicle maturation incorporates the activities of a range of proteins. Actin, myosin and WASP all have important roles in the formation and stabilization [...]
How does the clathrin-coated vesicle neck narrow?
How does the clathrin-coated vesicle neck narrow? In the final stages of clathrin-coated vesicle (CCV) formation, Phosphatidylinositol-4,5-bisphosphate (PIP2) undergoes a dephosphorylation by phosphatases such as synaptojanin 1 (Synj1) [1]. Not only does this inhibit [...]

Epithelial cell migration; microfabrication for cell mechanics; influence of the mechanical environments on cell functions; mechanotransduction
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.

MBI’s International Conference on Genomes and AI: From Packing to Regulation, October 2-4
MBI's upcoming conference will bring together leading international experts, early-career scientists and students at the intersection of genome biology and machine learning to spur new collaborations across disciplinary boundaries. This is critical for uncovering the mechanogenomic codes that link genome architecture, regulation and function, and ultimately for the development of new biomarkers and therapeutic interventions. The International Conference on Genomes and AI: From Packing to Regulation will cover the following three major themes: 1) Single-cell 1D and 3D Genomics: Experiments and Modeling, 2) Networks: From Expression to Regulatory Modules, and 3) Genome Architecture: Regulation and Biomarkers
