Endogenous Regulators of Gamma-Secretase and Amyloid-Beta Production, and Engineering of Alzheimer's Disease Therapeutic Tools

Sébastien Mosser

Alzheimer s disease (AD) is a devastating neurodegenerative disease characterized by strong cognitive impairment and memory loss. These symptoms are caused by neuronal death, induced by two pathological hallmarks: extracellular senile plaques composed of a ...

Contact Angle at the Leading Edge Controls Cell Protrusion Rate

László Forró, Jean-Jacques Meister, Niccolo Piacentini, Chiara Gabella, Alexander Verkhovskiy, Sylvia Jeney, Elena Bertseva, Alicia Carine Bornert

Plasma membrane tension and the pressure generated by actin polymerization are two antagonistic forces believed to define the protrusion rate at the leading edge of migrating cells [1-5]. Quantitatively, resistance to actin protrusion is a product of membr ...

Interplay between cytoskeletal forces, membrane tension and shape in rapidly migrating cells

Chiara Gabella

Cell migration is a fundamental process in all animal cells. The ability of cell to migrate is crucial for many pathological and physiological conditions such as morphogenesis, the immune response to inflammatory or vascular diseases and cancer metastasis. ...

Self-organization is a dynamic and lineage-intrinsic property of mammary epithelial cells

Léa Chanson

Loss of organization is a principle feature of cancers; therefore it is important to understand how normal adult multilineage tissues, such as bilayered secretory epithelia, establish and maintain their architectures. The self-organization process that dri ...

Regulation of cortical contractility and spindle positioning by the protein phosphatase 6 PPH-6 in one-cell stage C. elegans embryos

Pierre Gönczy

Modulation of the microtubule and the actin cytoskeleton is crucial for proper cell division. Protein phosphorylation is known to be an important regulatory mechanism modulating these cytoskeletal networks. By contrast, there is a relative paucity of infor ...

Force transmission in migrating cells

Jean-Jacques Meister, Alexander Verkhovskiy, Roger Sauser, Maxime Fred Maurice Fournier

During cell migration, forces generated by the actin cytoskeleton are transmitted through adhesion complexes to the substrate. To investigate the mechanism of force generation and transmission, we analyzed the relationship between actin network velocity an ...

Role of Bicaudal-C in Left-Right Axis Formation and Kidney Morphogenesis

Charlotte Maisonneuve

The KH domain RNA binding protein Bicaudal-C is known to play a role in anterior-posterior (AP) patterning in Drosophila by acting on oskar mRNA. In mammals, its expression is induced at late gastrulation in the mesodermal layer of the ventral node. Renal ...

Role of focal adhesions and mechanical stresses in the formation and progression of the lamellum interface

Alexander Verkhovskiy

Actin network in the front part of a moving cell is organized into a lamellipodium and a lamellum. A distinct lamellipodium-lamellum interface is associated with focal adhesions and consists of a series of arclike segments linking neighboring focal adhesio ...

Bicaudal C, a novel regulator of Dvl signaling abutting RNA-processing bodies, controls cilia orientation and leftward flow

Daniel Constam, Thomas Alois Weber, Charlotte Maisonneuve

Polycystic diseases and left-right (LR) axis malformations are frequently linked to cilia defects. Renal cysts also arise in mice and frogs lacking Bicaudal C (BicC), a conserved RNA-binding protein containing K-homology (KH) domains and a sterile alpha mo ...

Comparative dynamics of retrograde actin flow and focal adhesions: formation of nascent adhesions triggers transition from fast to slow flow

Jean-Jacques Meister, Alexander Verkhovskiy, Sébastien Schaub

Dynamic actin network at the leading edge of the cell is linked to the extracellular matrix through focal adhesions (FAs), and at the same time it undergoes retrograde flow with different dynamics in two distinct zones: the lamellipodium (peripheral zone o ...
