Nonequilibrium biochemical structures in two space dimensions with local activation and regulation

Autor: Bertrand Fourcade

Publikováno v: Physical Review E
Physical Review E, American Physical Society (APS), 2020, 101 (1), ⟨10.1103/PhysRevE.101.012420⟩

International audience; Integrin receptor (IR) clustering is an example of pattern self-organization in biological systems. We study a model for receptor activation whose content is guided by two major principles in cellular signal transduction: (i)

Multi-domain signaling proteins sample numerous stimuli to coordinate distinct cellular responses. Understanding the mechanisms of their pleiotropic signaling activity requires to directly manipulate their activity of decision leading to distinct cel

Fluctuation correlation models for receptor immobilization

Autor: Bertrand Fourcade

Publikováno v: Physical Review E
Physical Review E, American Physical Society (APS), 2017, 96 (6), ⟨10.1103/PhysRevE.96.062403⟩

Nanoscale dynamics with cycles of receptor diffusion and immobilization by cell-external-or-internal factors is a key process in living cell adhesion phenomena at the origin of a plethora of signal transduction pathways. Motivated by modern correlati

Integrin-mediated adhesion as self-sustained waves of enzymatic activation

Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 92 (4), ⟨10.1103/PhysRevE.92.042704⟩

Integrin receptors mediate interaction between the cellular actin-cytoskeleton and extracellular matrix. Based on their activation properties, we propose a reaction-diffusion model where the kinetics of the two-state receptors is modulated by their l

Biological cell detachment kinetics from an inert substrate

Autor: L. Boulange, Yves Bréchet, Emmanuel Décavé, Bertrand Fourcade, F. Bruckert, M. Demilly

Publikováno v: Philosophical Magazine. 85:3173-3189

A radial flow chamber was used to experimentally study the detachment kinescopes of deformable (Dictyostelium discoideum) and non-deformable (Saccharomyces cerevisiae) cells. In both cases, phenomenological laws were derived, defining detachment effi

Shear flow-induced motility ofDictyostelium discoideumcells on solid substrate

Application of a mild hydrodynamic shear stress to Dicytostelium discoideum cells, unable to detach cells passively from the substrate, triggers a cellular response consisting of steady membrane peeling at the rear edge of the cell and periodic cell

Fluctuations of a membrane interacting with a diffusion field

Autor: F. Divet, Angélique Stéphanou, Thierry Biben, Chaouqi Misbah, Isabelle Cantat, Bertrand Fourcade

Publikováno v: Europhysics Letters (EPL). 60:795-801

We analyze the dynamics and fluctuations of a phospholipidic membrane containing inclusions which may diffuse along the membrane as well as in the aqueous solution. A kinetic law of exchange between the membrane and the fluid is introduced. It is sho
