Shift-Invariant Spaces from Rotation-Covariant Functions

Michaël Unser, Dimitri Nestor Alice Van De Ville, Thierry Blu

We consider shift-invariant multiresolution spaces generated by rotation-covariant functions ρ in

\mathbb{R}^{ 2 }

. To construct corresponding scaling and wavelet functions, ρ has to be localized with an appropriate multiplier, such that the localized ...

Analysis of actin filament network organization in lamellipodia by comparing experimental and simulated images

Jean-Jacques Meister, Sébastien Schaub

Protrusion of lamellipodia during cell migration depends on the assembly of actin network. The assembly mechanism, based on dendritic filament branching, has been investigated in reconstituted in vitro systems, but little is known about the dynamical and s ...

Dynamics of actin and myosin II during cell polarization and directional locomotion

Sophie Bohnet

Crawling cell motility is characteristic of most animal cells and is involved in many important biological processes such as embryogenesis, immune response, and wound healing. It involves several steps: protrusion (dynamic surface extension) at the front o ...

Structure and dynamics of actin network at the leading edge of migrating cells

Sébastien Schaub

Crawling motion is characteristic of most animal cells and is principally based on actin-myosin II cytoskeletal system. The major components and reactions contributing to motility have been identified, but the overall picture of how these molecular events ...

The N-terminal Ac-EEED sequence plays a role in alpha-smooth-muscle actin incorporation into stress fibers

Boris Hinz

We have previously shown that the N-terminal sequence AcEEED of alpha-smooth-muscle actin causes the loss of alpha-smooth-muscle actin from stress fibers and a decrease in cell contractility when introduced in myofibroblasts as a cell-penetrating fusion pe ...

Gradient of Rigidity in the Lamellipodia of Migrating Cells Revealed by Atomic Force Microscopy

Giovanni Dietler, Jean-Jacques Meister, Sandor Kasas, Alexandre Yersin

Changes in mechanical properties of the cytoplasm have been implicated in cell motility, but there is little information about these properties in specific regions of the cell at specific stages of the cell migration process. Fish epidermal keratocytes wit ...

Gelsolin superfamily proteins: key regulators of cellular functions

Nikolaos Stergiopoulos, Paolo Silacci

Cytoskeletal rearrangement occurs in a variety of cellular processes and involves a wide spectrum of proteins. Among these, the gelsolin superfamily proteins control actin organization by severing filaments, capping filament ends and nucleating actin assem ...

Model of coupled transient changes of Rac, Rho, adhesions and stress fibers alignment in endothelial cells responding to shear stress

Jean-Jacques Meister, Alex Mogilner

Interactions of cell adhesions, Rho GTPases and actin in the endothelial cells' response to external forces are complex and not fully understood, but a qualitative understanding of the mechanosensory response begins to emerge. Here, we formulate a mathemat ...

Orientational order of the lamellipodial actin network as demonstrated in living motile cells

Jean-Jacques Meister, Sébastien Schaub

Lamellipodia of crawling cells represent both the motor for cell advance and the primary building site for the actin cytoskeleton. The organization of actin in the lamellipodium reflects actin dynamics and is of critical importance for the mechanism of cel ...

Analysis of actin dynamics at the leading edge of crawling cells: implications for the shape of keratocyte lamellipodia

Jean-Jacques Meister, Alex Mogilner

Leading edge protrusion is one of the critical events in the cell motility cycle and it is believed to be driven by the assembly of the actin network. The concept of dendritic nucleation of actin filaments provides a basis for understanding the organizatio ...
